MANAGEMENT’S DISCUSSION AND ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with our accompanying consolidated financial statements and notes thereto, which appear elsewhere in this document. In this discussion, all dollar amounts are presented in thousands, except share and per share data.

The following discussion contains forward-looking statements. We intend statements which are not historical in nature to be, and are hereby identified as “forward-looking statements” to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. In addition, the Company’s senior management may make forward-looking statements orally to analysts, investors, the media and others. This safe harbor requires that we specify important factors that could cause actual results to differ materially from those contained in forward-looking statements made by or on behalf of us. We cannot promise that our expectations in such forward-looking statements will turn out to be correct. Our actual results could be materially different from and worse than our expectations. See “Forward-Looking Statements” below for specific important factors that could cause actual results to differ materially from those contained in forward-looking statements.

Executive Summary and Overview

In this discussion, “Safety” refers to Safety Insurance Group, Inc. and “our Company,” “the Company,” “we,” “us” and “our” refer to Safety Insurance Group, Inc. and its consolidated subsidiaries. Our subsidiaries consist of Safety Insurance Company (“Safety Insurance”), Safety Indemnity Insurance Company (“Safety Indemnity”), Safety Property and Casualty Insurance Company (“Safety P&C”), Safety Northeast Insurance Company (“Safety Northeast”), Safety Northeast Insurance Agency, Inc. (“SNIA”), and Safety Management Corporation, which is SNIA’s holding company.

We are a leading provider of private passenger automobile, commercial automobile, homeowners and commercial other-than-auto insurance in Massachusetts. In addition to private passenger automobile insurance (which represented 54.9% of our direct written premiums in 2025), we offer a portfolio of other insurance products, including commercial automobile (15.2% of 2025 direct written premiums), homeowners (25.2% of 2025 direct written premiums) and dwelling fire, umbrella and business owner policies (totaling 4.7% of 2025 direct written premiums).  Operating exclusively in Massachusetts, New Hampshire, and Maine through our insurance company subsidiaries, Safety Insurance, Safety Indemnity, Safety P&C, and Safety Northeast (together referred to as the “Insurance Subsidiaries”), we have established strong relationships with independent insurance agents, who numbered 797 in 1,063 locations throughout these three states at December 31, 2025. We have used these relationships and our extensive knowledge of the Massachusetts market to become the third largest private passenger automobile carrier and the second largest commercial automobile insurance carrier in Massachusetts, capturing an approximate 9.4% and 13.0% share, respectively, of the Massachusetts private passenger and commercial automobile markets in 2025, according to statistics compiled by the Commonwealth Automobile Reinsurers (“CAR”) based on automobile exposures. We are also the third largest homeowners insurance carrier in Massachusetts with a 7.0% share of the Massachusetts homeowners insurance market in 2024.

A.M. Best, which rates insurance companies based on factors of concern to policyholders, currently assigns Safety Insurance an "A (Excellent)" rating. Our "A" rating was reaffirmed by A.M. Best on June 20, 2025.

Beginning on February 22, 2026, the Northeast region experienced a severe winter weather event (“February Winter Storm”), which produced record-breaking snowfall and hurricane-force wind gusts. Areas in the region received up to 36 inches of snowfall and wind gusts exceeding 80 miles per hour. As a result of the February Winter Storm, the Company received approximately 450 reported claims totaling $10,163 of losses and loss adjustment expenses for the three months ended March 31, 2026.

Direct and Net Written Premiums. For the three months ended March 31, 2026, direct written premium growth and net written premium growth were 0.3% and 0.2%, respectively. The increase in premium is driven by rate increases. For the three months ended March 31, 2026, average written premium per policy increased 4.0%, 6.1% and 9.9% in Private Passenger Automobile, Commercial Automobile and Homeowners lines, respectively, compared to the same period in 2025.

Losses and Loss Adjustment Expenses.  Losses and loss adjustment expenses incurred for the three months ended March 31, 2026 increased by $57,200 or 30.1%, to $247,490 from $190,290 for the comparable period. Our losses and loss adjustment expenses ratio for the three months ended March 31, 2026 increased to 85.1% from 69.8% for the comparable 2025 period. The increase in losses is primarily due to the impact of the Winter Storms.

Insurance Ratios

The property and casualty insurance industry uses the combined ratio as a measure of underwriting profitability. The combined ratio is the sum of the loss ratio (losses and loss adjustment expenses incurred as a percent of net earned premiums) plus the expense ratio (underwriting and other expenses as a percent of net earned premiums, calculated on a Generally Accepted Accounting Principles (“GAAP”) basis).  The combined ratio reflects only underwriting results and does not include income from investments or finance and other service income.  Underwriting profitability is subject to significant fluctuations due to competition, catastrophic events, weather, economic and social conditions, and other factors.

Our GAAP insurance ratios are outlined in the following table.

Share-Based Compensation

On March 24, 2022, the Company’s Board of Directors adopted the Amended and Restated Safety Insurance Group, Inc. 2018 Long-Term Incentive Plan (the “Amended 2018 Plan”), which was subsequently approved by our shareholders at the 2022 Annual Meeting of Shareholders. The Amended 2018 Plan increases the share pool limit by adding 350,000 common shares to the previously adopted Safety Insurance Group, Inc. 2018 Long-Term Incentive Plan. The Amended 2018 Plan enables the grant of stock awards, performance shares, cash-based performance units, other stock-based awards, stock options, stock appreciation rights, and stock unit awards, each of which may be granted separately or in tandem with other awards. Eligibility to participate includes officers, directors, employees and other individuals who provide bona fide services to the Company. The Amended 2018 Plan supersedes the Company’s 2002 Management Omnibus Incentive Plan (“the 2002 Incentive Plan”).

The Amended 2018 Plan establishes a pool of 700,000 shares of common stock available for issuance to our employees and other eligible participants. The Board of Directors and the Compensation Committee intend to issue awards under the Amended 2018 Plan in the future.

The maximum number of shares of common stock between both the Amended 2018 Plan and 2002 Incentive Plan with respect to which awards may be granted is 3,200,000. No further grants will be allowed under the 2002 Incentive Plan. At March 31, 2026, there were 160,334 shares available for future grant.

A summary of share based awards granted under the Incentive Plan during the three months ended March 31, 2026 is as follows:

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with our accompanying consolidated financial statements and notes thereto, which appear elsewhere in this document. In this discussion, all dollar amounts are presented in thousands, except share and per share data.

The following discussion contains forward-looking statements. We intend statements which are not historical in nature to be and are hereby identified as “forward-looking statements” to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. In addition, the Company’s senior management may make forward-looking statements orally to analysts, investors, the media and others. This safe harbor requires that we specify important factors that could cause actual results to differ materially from those contained in forward-looking statements made by or on behalf of us. We cannot promise that our expectations in such forward-looking statements will turn out to be correct. Our actual results could be materially different from and worse than our expectations. See “Forward-Looking Statements” below for specific important factors that could cause actual results to differ materially from those contained in forward-looking statements.

Executive Summary and Overview

In this discussion, “Safety” refers to Safety Insurance Group, Inc. and “our Company,” “we,” “us” and “our” refer to Safety Insurance Group, Inc. and its consolidated subsidiaries. Our subsidiaries consist of Safety Insurance Company (“Safety Insurance”), Safety Indemnity Insurance Company (“Safety Indemnity”), Safety Property and Casualty Insurance Company (“Safety P&C”), Safety Northeast Insurance Company (“Safety Northeast”), Safety Northeast Insurance Agency, Inc. (“SNIA”), and Safety Management Corporation (“SMC”), which is SNIA’s holding company.

We are a leading provider of private passenger automobile (54.9% of our direct written premiums in 2025), commercial automobile, (15.2% of 2025 direct written premiums), and homeowners (25.2% of 2025 direct written premiums) insurance. In addition to these coverages, we offer a portfolio of other insurance products, including dwelling fire, umbrella and business owner policies (totaling 4.7% of 2025 direct written premiums). Operating exclusively in Massachusetts, New Hampshire and Maine through our insurance company subsidiaries, Safety Insurance, Safety Indemnity, Safety P&C, and Safety Northeast (together referred to as the “Insurance Subsidiaries”), we have established strong relationships with independent insurance agents, who numbered 797 in 1,063 locations throughout these three states during 2025. We have used these relationships and our extensive knowledge of the market to become the fourth largest private passenger automobile carrier and the largest commercial automobile carrier in Massachusetts, capturing an approximate 9.4% and 13.0% share, respectively, of the Massachusetts private passenger and commercial automobile markets in 2025, according to statistics compiled by the Commonwealth Automobile Reinsurers (“CAR”) based on automobile exposures. We are the third largest homeowners insurance carrier in Massachusetts, with a market share of 7.0% in 2024.

A.M. Best, which rates insurance companies based on factors of concern to policyholders, currently assigns Safety Insurance an “A (Excellent)” rating. Our “A” rating was reaffirmed by A.M. Best on June 20, 2025.

Our Insurance Subsidiaries began writing insurance in New Hampshire during 2008 and Maine in 2016. In November 2020, we formed a fourth insurance subsidiary, Safety Northeast, which became licensed to write insurance products in Massachusetts. The table below shows the amount of direct written premiums in each state during the years ended December 31, 2025, 2024, and 2023.

Losses and Loss Adjustment Expenses. Losses and loss adjustment expenses incurred for the three months ended December 31, 2025 increased by $14,671, or 7.6%, to $207,678 from $193,007 for the comparable 2024 period. Losses and loss adjustment expenses incurred for the year ended December 31, 2025 increased by $80,545, or 11.2%, to $797,182 from $716,637 for the comparable 2024 period. The increase in losses for both periods ended December 31, 2025 is primarily driven by our larger policy counts and current market conditions, specifically inflationary impacts on our Private Passenger Automobile book of business.

Loss, expense, and combined ratios calculated under U.S. generally accepted accounting principles (“GAAP”) for the quarter ended December 31, 2025 were 70.8%, 28.6%, and 99.4%, respectively, compared to 71.7%, 30.2%, and 101.9%, respectively, for the comparable 2024 period. Loss, expense, and combined ratios calculated under U.S. GAAP for the year ended December 31, 2025 were 70.0%, 29.0%, and 99.0%, respectively, compared to 70.9%, 30.2%, and 101.1%, respectively, for the comparable 2024 period. The 2025 decrease in the loss ratios is due to growth in earned premiums, slightly offset by increased loss severity. The decrease in the expense ratios in both periods is primarily driven by growth in earned premiums.

We define a “catastrophe” as an event that produces pre-tax losses before reinsurance in excess of $1,000 and involves multiple first-party policyholders, or an event that produces a number of claims in excess of a preset, per-event threshold of average claims in a specific area, occurring within a certain amount of time following the event. Catastrophes are caused by various natural events including high winds, winter storms, tornadoes, hailstorms, and hurricanes. The nature and level of catastrophes in any period cannot be reliably predicted.

Catastrophe losses incurred by the type of event are shown in the following table.

Statutory Accounting Principles

Our results are reported in accordance with GAAP, which differ from amounts reported in accordance with statutory accounting principles ("SAP") as prescribed by insurance regulatory authorities, which in general reflect a liquidating, rather than going concern concept of accounting. Specifically, under GAAP:

Column 1Column 2Column 3
Policy acquisition costs such as commissions, premium taxes and other variable costs incurred which are directly related to the successful acquisition of a new or renewal insurance contract are capitalized and amortized on a pro rata basis over the period in which the related premiums are earned, rather than expensed as incurred, as required by SAP.

Column 1Column 2Column 3
Certain assets are included in the consolidated balance sheets whereas, under SAP, such assets are designated as "nonadmitted assets," and charged directly against statutory surplus. These assets consist primarily of premium receivables that are outstanding over ninety days, federal deferred tax assets in excess of statutory limitations, furniture, equipment, leasehold improvements and prepaid expenses.

Column 1Column 2Column 3
Amounts related to ceded reinsurance are shown gross of ceded unearned premiums and reinsurance recoverables, rather than netted against unearned premium reserves and loss and loss adjustment expense reserves, respectively, as required by SAP.

Column 1Column 2Column 3
Fixed maturities securities, which are classified as available-for-sale, are reported at current fair values, rather than at amortized cost, or the lower of amortized cost or market, depending on the specific type of security, as required by SAP.

Column 1Column 2Column 3
The differing treatment of income and expense items results in a corresponding difference in federal income tax expense. Changes in deferred income taxes are reflected as an item of income tax benefit or expense, rather than recorded directly to surplus as regards policyholders, as required by SAP. Admittance testing may result in a charge to unassigned surplus for non-admitted portions of deferred tax assets. Under GAAP reporting, a valuation allowance may be recorded against the deferred tax asset and reflected as an expense.

Insurance Ratios

The property and casualty insurance industry uses the combined ratio as a measure of underwriting profitability. The combined ratio is the sum of the loss ratio (losses and loss adjustment expenses incurred as a percent of net earned premiums) plus the expense ratio (underwriting and other expenses as a percent of net earned premiums, calculated on a GAAP basis). The combined ratio reflects only underwriting results and does not include income from

investments or finance and other service income. Underwriting profitability is subject to significant fluctuations due to competition, catastrophic events, weather, economic and social conditions, and other factors.

Share-Based Compensation

On March 24, 2022, the Company’s Board of Directors adopted the Amended and Restated Safety Insurance Group, Inc. 2018 Long-Term Incentive Plan (the “Amended 2018 Plan”), which was subsequently approved by our shareholders at the 2022 Annual Meeting of Shareholders. The Amended 2018 Plan increases the share pool limit by adding 350,000 common shares to the previously adopted Safety Insurance Group, Inc. 2018 Long-Term Incentive Plan. The Amended 2018 Plan enables the grant of stock awards, performance shares, cash-based performance units, other stock-based awards, stock options, stock appreciation rights, and stock unit awards, each of which may be granted separately or in tandem with other awards. Eligibility to participate includes officers, directors, employees and other individuals who provide bona fide services to the Company. The Amended 2018 Plan supersedes the Company’s 2002 Management Omnibus Incentive Plan (“the 2002 Incentive Plan”).

The Amended 2018 Plan establishes a pool of 700,000 shares of common stock available for issuance to our employees and other eligible participants. The Board of Directors and the Compensation Committee intend to issue awards under the Amended 2018 Plan in the future.

The maximum number of shares of common stock between both the 2018 Amended Plan and 2002 Incentive Plan with respect to which awards may be granted is 3,200,000. No further grants will be allowed under the 2002 Incentive Plan. At December 31, 2025, there were 235,663 shares available for future grant. Grants outstanding under the plans as of December 31, 2025, were comprised of 148,902 restricted shares.

(1)  The fair value per share of the restricted stock grant is equal to the closing price of our common stock on the grant date.

(2) Board of Director members must maintain stock ownership equal to at least four times their annual cash retainer. This requirement must be met within five years of becoming a director.

(3) The shares represent performance-based restricted shares award. Vesting of these shares is dependent upon the attainment of pre-established performance objectives, and any difference between shares granted and shares earned at the end of the performance period will be reported at the conclusion of the performance period.

(4) The shares represent a true-up of previously awarded performance-based restricted share awards. The updated shares were calculated based on the attainment of pre-established performance objectives and granted under the Amended 2018 Plan.

Reinsurance

We reinsure with other insurance companies a portion of our potential liability under the policies we have underwritten, thereby protecting us against an unexpectedly large loss or a catastrophic occurrence that could produce large losses, primarily in our homeowners line of business. We use various software products to measure our exposure to catastrophe losses and the probable maximum loss to us for catastrophe losses such as hurricanes. The reinsurance market has seen from the various software modelers, increases in the estimate of damage from hurricanes in the southern and northeast portions of the United States due to revised estimations of increased hurricane activity and increases in the estimation of demand surge in the periods following a significant event. We continue to manage and model our exposure and adjust our reinsurance programs as a result of the changes to the models. As of January 1, 2025, we purchased three layers of excess catastrophe reinsurance providing $675,000 of coverage for property losses in excess of $75,000 up to a maximum of $750,000. Our reinsurers’ co-participation is 85.0% of $75,000 for the 1st layer, 85.0% of $250,000 for the 2nd layer, and 85.0% of $350,000 for the 3rd layer. As a result of the changes to the models, our catastrophe reinsurance in 2025 protects us in the event of a “138-year storm” (that is, a storm of a severity expected to occur once in a 138-year period). Most of our reinsurers have an A.M. Best rating of “A+” (Superior) or “A” (Excellent).

We are a participant in CAR, a state-established body that runs the residual market reinsurance programs for commercial automobile insurance in Massachusetts under which premiums, expenses, losses and loss adjustment expenses on ceded business are shared by all insurers writing commercial automobile insurance in Massachusetts.

We also had $169,596 due from CAR comprising of loss and loss adjustment expense reserves, unearned premiums and reinsurance recoverables.

Non-GAAP Measures

Management has included certain non-generally accepted accounting principles (“non-GAAP”) financial measures in presenting the Company’s results. Management believes that these non-GAAP measures better explain the

44

Table of Contents

Company’s results of operations and allow for a more complete understanding of the underlying trends in the Company’s business. These measures should not be viewed as a substitute for those determined in accordance with GAAP. In addition, our definitions of these items may not be comparable to the definitions used by other companies.

Non-GAAP operating income and non-GAAP operating income per diluted share consist of our GAAP net income adjusted by the net realized gains on investments, net impairment losses on investments, changes in net unrealized gains on equity securities, credit loss benefit (expense) and taxes related thereto. Net income and earnings per diluted share are the GAAP financial measures that are most directly comparable to non-GAAP operating income and non-GAAP operating income per diluted share, respectively. A reconciliation of the GAAP financial measures to these non-GAAP measures is included in the financial highlights below.

Net Investment Income.  Net investment income for the year ended December 31, 2025 increased by $7,012, or 12.6%, to $62,732 from $55,720 for the comparable 2024 period. The increase was primarily driven by higher assets under management, reinvestment rates that exceeded the yields on maturing securities, and strong alternative asset returns. Net effective annual yield on the investment portfolio was 4.0% for the year ended December 31, 2025, compared to 3.9% for comparable 2024 period. Our duration was 3.9 years at December 31, 2025, compared to 3.5 years at December 31, 2024.

Earnings from Partnership Investments. Earnings from partnership investments were $8,461 for the year ended December 31, 2025 compared to $10,271 for the year ended December 31, 2024. The 2025 earnings reflect a decrease in investment appreciation and distribution of investment returns compared to the prior year. Timing and generation of these returns on capital can vary based on the results and transactions of the underlying partnerships.

Net Realized Gains on Investments.  Net realized gains on investments were $17,982 for the year ended December 31, 2025 compared to $7,720 for the comparable 2024 period. The increase was primarily driven by gains realized from the sale of mutual fund holdings within our equity security portfolio.

The gross unrealized gains and losses on investments in fixed maturity securities, equity securities, including interests in mutual funds, and other invested assets were as follows:

As of December 31, 2025, the fixed maturity portfolio was primarily composed of investment‑grade corporate securities, U.S. government and agency securities, asset‑backed securities, and investment‑grade collateralized loan obligations (“CLOs”). During the year, management undertook a strategic repositioning that reduced exposure to below‑investment‑grade senior secured bank loans and increased allocations to investment‑grade CLOs. These actions resulted in an improvement in the overall credit quality of the portfolio. The portion of our non‑investment‑grade fixed maturity portfolio is primarily comprised of high‑yield bonds.

The following table illustrates the gross unrealized losses included in our investment portfolio and the fair value of those securities, aggregated by investment category. The table also presents the length of time that they have been in a continuous unrealized loss position of December 31, 2025.

The Company’s analysis of its fixed maturity portfolio as of December 31, 2025 concluded that none of the unrealized losses in the fixed maturity portfolio were due to credit factors; therefore, no allowance for credit losses was recorded compared to an allowance of $1,198 as of December 31, 2024. The Company concluded that, other than securities previously identified as credit-impaired, the unrealized losses recorded on the fixed maturity portfolio at December 31, 2025 and 2024 were driven by changes in market interest rates and other temporary market conditions as opposed to fundamental changes in the credit quality of the issuers of such securities. Based upon the analysis performed, the Company’s decision to hold these securities, the Company’s current level of liquidity and our history of positive operating cash flows, management believes it is more likely than not that it will not be required to sell any of its securities before the anticipated recovery in the fair value to its amortized cost basis.

Specific qualitative analysis was also performed for securities appearing on our “Watch List,” if any. Qualitative analysis considered such factors as the financial condition and the near term prospects of the issuer, whether the debtor is current on its contractually obligated interest and principal payments, changes to the rating of the security by a rating agency and the historical volatility of the fair value of the security.

Commission Income: Commission income includes revenues from new and renewal commissions paid by insurance carriers, which we recognize when earned. Commission income was $9,498 and $7,942 for the years ended December 31, 2025 and 2024, respectively. The year-over-year change is driven by policy count growth and increased premium rates across the property and casualty insurance market.

Finance and Other Service Income.  Finance and other service income includes revenues from premium installment charges, which we recognize when earned, and other miscellaneous income and fees. Finance and other service income increased by $1,952, or 8.2%, to $25,652 for the year ended December 31, 2025 from $23,700 for the comparable 2024 period. The increase is primarily driven by the increase in policy counts and changes to our fee assessment policies.

Losses and Loss Adjustment Expenses.  Losses and loss adjustment expenses incurred for the year ended December 31, 2025 increased by $80,545, or 11.2%, to $797,182 from $716,637 for the comparable 2024 period.

Our GAAP loss ratio for the years ended December 31, 2025 and 2024 were 70.0% and 70.9%, respectively. Our GAAP loss ratio excluding loss adjustment expenses was 62.3% and 62.6% for the years ended December 31, 2025 and 2024, respectively. Total prior year favorable development included in the pre-tax results for the year ended December 31, 2025 was $44,552, compared to $51,894 for the comparable 2024 period. The decrease in favorable prior year development in 2025 is primarily attributable to the inclusion of $8,644 of FAIR Plan development in the prior year.

Underwriting, Operating and Related Expenses.  Underwriting, operating and related expenses for the year ended December 31, 2025 increased by $25,074, or 8.2%, to $330,396 from $305,322 for the comparable 2024 period. The increase is driven by an increase in base commissions resulting from the increase in written premiums. Our GAAP

48

Table of Contents

expense ratio for the year ended December 31, 2025 decreased to 29.0% from 30.2% for the comparable 2024 period due to higher earned premium.

Other Expense: Other expense includes the operating and related expenses associated with SNIA.

Interest Expense.  Interest expense was $1,530 and $509 for the years ended December 31, 2025 and 2024, respectively. The credit facility commitment fee included in interest expense was $14 and $60 for the years ended December 31, 2025 and 2024, respectively. The increase in interest expense during the current year is primarily due to the new borrowings under the Company’s existing Credit Agreement with Citizens Bank on March 27, 2025, which carries an interest rate of SOFR rate plus 1.25%, compared to the repaid FHLB loan that had a fixed rate of 1.42%. Additionally, the Company no longer incurs a credit facility commitment fee as of March 27, 2025, since a loan is currently outstanding under the facility. For further information, refer to Item 8 – Financial Statements and Supplementary Data, Note 10, Debt, of this Form 10‑K.

Income Tax Expense.  Our effective tax rates were 21.7% and 21.3% for the years ended December 31, 2025 and 2024, respectively. The effective rates for the year ended December 31, 2025 and 2024 were higher than the statutory rate primary due to the impact of stock-based and executive compensation.

The comparison of results for the year ended December 31, 2024 compared to the year ended December 31, 2023 can be found in the Company’s 2024 Annual Report on Form 10-K filed with the SEC on February 27, 2025.

Liquidity and Capital Resources

As a holding company, Safety’s assets consist primarily of the stock of our direct and indirect subsidiaries. Our principal source of funds to meet our obligations and pay dividends to shareholders, therefore, is dividends and other permitted payments from our subsidiaries, principally Safety Insurance. Safety is the borrower under our credit facility.

Safety Insurance’s sources of funds primarily include premiums received, investment income and proceeds from sales and redemptions of investments. Safety Insurance’s principal uses of cash are the payment of claims, operating expenses and taxes, the purchase of investments and payment of dividends to Safety.

Net cash provided by operating activities was $194,498, $128,688, and $52,114 during the years ended December 31, 2025, 2024, and 2023, respectively. Our operations typically generate positive cash flows from operations as most premiums are received in advance of the time when claim and benefit payments are required. These positive operating cash flows are expected to continue to meet our liquidity requirements.

Net cash used for investing activities was $125,706 and $54,541 during the years ended December 31, 2025 and 2024, respectively. Net cash provided by investing activities was $24,269 for the year ended December 31, 2023. This fluctuation was driven by purchases exceeding proceeds from sales, paydowns, calls and maturities of fixed maturity and equity securities in 2025.

Net cash used for financing activities was $53,865, $53,325, and $63,531 during the years ended December 31, 2025, 2024 and 2023, respectively. Net cash used for financing activities during the year ended December 31, 2025 consisted of dividend payments to shareholders, the acquisition of treasury stock and payments on a loan that matured during the year, partially offset by proceeds from a new loan.

The Insurance Subsidiaries maintain a high degree of liquidity within their respective investment portfolios in fixed maturity and short-term investments. We do not anticipate the need to sell these securities to meet the Insurance Subsidiaries cash requirements. We expect the Insurance Subsidiaries to generate sufficient operating cash to meet all short-term and long-term cash requirements. However, there can be no assurance that unforeseen business needs or other items will not occur causing us to have to sell securities before their values fully recover; thereby causing us to recognize additional impairment charges in that time period.

Regulatory Matters

Our insurance company’s subsidiaries are subject to various regulatory restrictions that limit the maximum amount of dividends available to be paid to their parent without prior approval of the Commissioner. The Massachusetts statute limits the dividends an insurer may pay in any twelve-month period, without the prior permission of the Commissioner, to the greater of (i) 10% of the insurer’s surplus as of the preceding December 31 or (ii) the insurer’s net income for the twelve-month period ending the preceding December 31, in each case determined in accordance with statutory accounting practices. Our Insurance Subsidiaries may not declare an “extraordinary dividend” (defined as any dividend or distribution that, together with other distributions made within the preceding twelve months, exceeds the limits established by Massachusetts statute) until thirty days after the Commissioner has received notice of the intended dividend and has not objected. As historically administered by the Commissioner, this provision requires the Commissioner’s prior approval of an extraordinary dividend. Under Massachusetts law, an insurer may pay cash dividends only from its unassigned funds, also known as earned surplus, and the insurer’s remaining surplus must be both reasonable in relation to its outstanding liabilities and adequate to its financial needs. At year-end 2025, the statutory surplus of Safety Insurance was $833,432, and its net income for 2025 was $83,092. As a result, a maximum of $83,343 is available in 2026 for such dividends without prior approval of the Commissioner. As a result of this Massachusetts statute, the Insurance Subsidiaries had restricted net assets in the amount of $750,089 at December 31, 2025. During the twelve months ended December 31, 2025, Safety Insurance paid dividends to Safety of $51,993.

The maximum dividend permitted by law is not indicative of an insurer’s actual ability to pay dividends, which may be constrained by business and regulatory considerations, such as the impact of dividends on surplus, which could affect an insurer’s ratings or competitive position, the amount of premiums that can be written and the ability to pay future dividends.

Since the initial public offering of its common stock in November 2002, the Company has paid regular quarterly dividends to shareholders of its common stock. Quarterly dividends paid during 2025 and 2024 were as follows:

On February 13, 2026, our Board approved and declared a quarterly cash dividend on our common stock of $0.92 per share to be paid on March 13, 2026 to shareholders of record on March 2, 2026. We plan to continue to declare and pay quarterly cash dividends in 2026, depending on our financial position and the regularity of our cash flows.

On February 23, 2022, the Board approved a share repurchase program of up to $50,000 of the Company’s outstanding common shares. The Board of Directors had cumulatively authorized increases to the existing share repurchase program of up to $200,000 of its outstanding common shares. Under the program, the Company may repurchase shares of its common stock for cash in public or private transactions, in the open market or otherwise. The timing of such repurchases and actual number of shares repurchased will depend on a variety of factors including price, market conditions and applicable regulatory and corporate requirements. The program does not require the Company to repurchase any specific number of shares and may be modified, suspended or terminated at any time without prior notice.

During the three months ended December 31, 2025, the Company purchased 262,370 shares at a cost of $20,000. No share purchases were made by the Company during the three months ended December 31, 2024. For the year ended December 31, 2025, the Company purchased 262,370 shares at a cost of $20,000. No shares were purchased by the Company during the year ended December 31, 2024. Included in the cost of treasury stock acquired during 2025, in the consolidated statement of shareholders’ equity, is the one percent excise tax imposed as part of the Inflation Reduction Act, which became effective January 1, 2023. As of December 31, 2025 and 2024, the Company had purchased 3,478,060 and 3,215,690 shares at cost of $175,240 and $155,240, respectively

Management believes that the current level of cash flow from operations provides us with sufficient liquidity to meet our operating needs over the next 12 months. We expect to be able to continue to meet our operating needs after the next 12 months from internally generated funds. Since our ability to meet our obligations in the long term (beyond such twelve-month period) is dependent upon such factors as market changes, insurance regulatory changes and economic conditions, no assurance can be given that the available net cash flow will be sufficient to meet our operating needs. We expect that we would need to borrow or issue capital stock if we needed additional funds, for example, to pay for an acquisition or a significant expansion of our operations. There can be no assurance that sufficient funds for any of the foregoing purposes would be available to us at such time.

Contractual Obligations

We have obligations to make future payments under contracts and credit-related financial instruments and commitments.

As of December 31, 2025, the Company had loss and LAE reserves of $761,739, unpaid reinsurance recoverables of $149,441 and net loss and LAE reserves of $612,298. Our loss and LAE reserves are estimates as described in more detail under Critical Accounting Policies and Estimates. The specific amounts and timing of obligations related to case reserves, IBNR reserves and related LAE reserves are not set contractually, and the amounts and timing of these obligations are unknown. While management believes that historical performance of loss payment patterns is a reasonable source for projecting future claims payments, there is inherent uncertainty in this estimated projected settlement of loss and LAE reserves, and as a result these estimates will differ, perhaps significantly, from actual future payments.

As part of the Company’s investment activity, we have committed $170,000 to investments in limited partnerships. The Company has contributed $152,626 to these commitments as of December 31, 2025. As of December 31, 2025, the remaining committed capital that could be called is $29,112, which includes potential recallable capital distributions.

Critical Accounting Policies and Estimates

Loss and Loss Adjustment Expense Reserves

Significant periods of time can elapse between the occurrence of an insured loss, the reporting to us of that loss and our final payment of that loss. To recognize liabilities for unpaid losses, we establish reserves as balance sheet

51

Table of Contents

liabilities. Our reserves represent estimates of amounts needed to pay reported and estimated losses incurred but not yet reported (“IBNR”) and the expenses of investigating and paying those losses, or loss adjustment expenses. Every quarter, we review our previously established reserves and adjust them, if necessary.

When a claim is reported, claims personnel establish a “case reserve” for the estimated amount of the ultimate payment. The amount of the reserve is primarily based upon an evaluation of the type of claim involved, the circumstances surrounding each claim and the policy provisions relating to the loss. The estimate reflects the informed judgment of such personnel based on general insurance reserving practices and on the experience and knowledge of the claims professional. During the loss adjustment period, these estimates are revised as deemed necessary by our claims department based on subsequent developments and periodic reviews of the cases. When a claim is closed with or without a payment, the difference between the case reserve and the settlement amount creates a reserve deficiency if the payment exceeds the case reserve or a reserve redundancy if the payment is less than the case reserve.

In accordance with industry practice, we also maintain reserves for IBNR. IBNR reserves are determined in accordance with commonly accepted actuarial reserving techniques on the basis of our historical information and experience. We review and make adjustments to incurred but not yet reported reserves quarterly. In addition, IBNR reserves can also be expressed as the total loss reserves required less the case reserves on reported claims.

When reviewing reserves, we analyze historical data and estimate the impact of various loss development factors, such as our historical loss experience and that of the industry, trends in claims frequency and severity, our mix of business, our claims processing procedures, legislative enactments, judicial decisions, legal developments in imposition of damages, and changes and trends in general economic conditions, including the effects of inflation. A change in any of these factors from the assumption implicit in our estimate can cause our actual loss experience to be better or worse than our reserves, and the difference can be material. There is no precise method, however, for evaluating the impact of any specific factor on the adequacy of reserves, because the eventual development of reserves is affected by many factors.

In estimating all our loss reserves, we follow the guidance prescribed by ASC 944, Financial Services – Insurance.

Management determines our loss and loss adjustment expense reserves estimate based upon the analysis of our actuaries. A reasonable estimate is derived by selecting a point estimate within a range of indications as calculated by our actuaries using generally accepted actuarial techniques. The key assumption in most actuarial analysis is that past patterns of frequency and severity will repeat in the future, unless a significant change in the factors described above takes place. Our key factors and resulting assumptions are the ultimate frequency and severity of claims, based upon the most recent ten years of claims reported to the Company, and the data CAR reports to us to calculate our share of the residual market, as of the date of the applicable balance sheet. For each accident year and each coverage within a line of business our actuaries calculate the ultimate losses incurred. Our total reserves are the difference between the ultimate losses incurred and the cumulative loss and loss adjustment payments made to date. Our IBNR reserves are calculated as the difference between our total reserves and the outstanding case reserves at the end of the accounting period. To determine ultimate losses, our actuaries calculate a range of indications and select a point estimation using such actuarial techniques as:

Column 1Column 2Column 3
Paid Loss Indications: This method projects ultimate loss estimates based upon extrapolations of historic paid loss trends. This method tends to be used on short tail lines such as automobile physical damage.
Column 1Column 2Column 3
Incurred Loss Indications: This method projects ultimate loss estimates based upon extrapolations of historic incurred loss trends. This method tends to be used on long tail lines of business such as automobile liability and homeowner’s liability.
Column 1Column 2Column 3
Bornhuetter-Ferguson Indications: This method projects ultimate loss estimates based upon extrapolations of an expected amount of IBNR, which is added to current incurred losses or paid losses. This method tends to be used on small, immature, or volatile lines of business, such as our BOP and umbrella lines of business.

Column 1Column 2Column 3
Bodily Injury Code Indications: This method projects ultimate loss estimates for our private passenger and commercial automobile bodily injury coverage based upon extrapolations of the historic number of accidents and the historic number of bodily injury claims per accident. Projected ultimate bodily injury claims are then segregated into expected claims by type of injury (e.g. soft tissue injury vs. hard tissue injury) based on past experience. An ultimate severity, or average paid loss amounts, is estimated based upon extrapolating historic trends. Projected ultimate loss estimates using this method are the aggregate of estimated losses by injury type.

Such techniques assume that past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate basis for predicting our ultimate losses, total reserves and resulting IBNR reserves. It is possible that the final outcome may fall above or below these amounts as a result of a number of factors, including immature data, sparse data, or significant growth in a line of business. Using these methodologies our actuaries established a range of reasonably possible estimations for net reserves of approximately $573,526 to $640,415 as of December 31, 2025 compared to a range of $497,512 to $566,772 as of December 31, 2024. In general, the low and high values of the ranges represent reasonable minimum and maximum values of the indications based on the techniques described above. Our selected point estimate of net loss and loss adjustment expense reserves based upon the analysis of our actuaries was $612,298 as of December 31, 2025 compared to $540,877 as of December 31, 2024.

The following table presents the point estimation of the recorded reserves and the range of estimations by line of business for net loss and LAE reserves as of December 31, 2025.

At December 31, 2025 and 2024, our total IBNR reserves for our private passenger automobile line of business were comprised of ($90,414) and ($98,528) related to estimated ultimate decreases in the case reserves, including anticipated recoveries (i.e. salvage and subrogation), and $43,297 and $41,462 related to our estimation for not yet reported losses, respectively.

Our IBNR reserves consist of our estimate of the total loss reserves required less our case reserves. The IBNR reserves for CAR assumed commercial automobile business are 40.6% of our total reserves for CAR assumed commercial automobile business as of December 31, 2025 due to the reporting delays in the information we receive from CAR, as described further in the section on Residual Market Loss and Loss Adjustment Expense Reserves.

Residual Market Loss and Loss Adjustment Expense Reserves

We are a participant in CAR and other various residual markets and assume a portion of losses and LAE on business ceded by the industry participants to the residual markets. We were a participant in the FAIR Plan until the recent FAIR Plan Restructuring in 2024. We estimate reserves for assumed losses and LAE that have not yet been reported to us by the residual markets. Our estimations are based upon the same factors we use for our own reserves, plus additional factors due to the nature of and the information we receive.

Residual market deficits consist of premium ceded to the various residual markets less losses and LAE and is allocated among insurance companies based on a various formulas (the “Participation Ratio”) that take into consideration a company’s voluntary market share.

Because of the lag in the various residual market estimations, and in order to try to validate to the extent possible the information provided, we estimate the effects of the actions of our competitors in order to establish our Participation Ratio.

Although we rely to a significant extent in setting our reserves on the information the various residual markets provide, we are cautious in our use of that information, because of the delays in receiving data from the various residual markets. As a result, we have to estimate our Participation Ratio and these reserves are subject to significant judgments and estimates.

Sensitivity Analysis

Establishment of appropriate reserves is an inherently uncertain process. There can be no certainty that currently established reserves based on our key assumptions regarding frequency and severity in our lines of business, or our assumptions regarding our share of the CAR loss will prove adequate in light of subsequent actual experience. To the extent that reserves are inadequate and are strengthened, the amount of such increase is treated as a charge to earnings in the period that the deficiency is recognized. To the extent that reserves are redundant and are released, the amount of the release is a credit to earnings in the period the redundancy is recognized. For the twelve months ended December 31, 2025, a 1 percentage-point change in the loss and LAE ratio would result in a change in reserves of $11,391. Each 1 percentage-point change in the loss and loss expense ratio would have had a $8,999 effect on net income, or $0.61 per diluted share.

Our assumptions consider that past experience, adjusted for the effects of current developments and anticipated trends, are an appropriate basis for establishing our reserves. Our individual key assumptions could each have a reasonable possible range of plus or minus 5 percentage-points for each estimation, although there is no guarantee that our assumptions will not have more than a 5 percentage point variation. The following sensitivity tables present information for each of our primary lines of business on the effect each 1 percentage-point change in each of our key assumptions on unpaid frequency and severity could have on our retained (i.e., direct minus ceded) loss and LAE reserves and net income for the twelve months ended December 31, 2025. In evaluating the information in the table, it should be noted that a 1 percentage-point change in a single assumption would change estimated reserves by 1 percentage-point. A 1 percentage-point change in both our key assumptions would change estimated reserves within a range of plus or minus 2 percentage-points.

Our estimated share of CAR loss and LAE reserves is based on assumptions about our Participation Ratio, the size of CAR, and the resulting deficit. Our assumptions consider that past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate basis for establishing our CAR reserves. Each of our assumptions could have a reasonably possible range of plus or minus 5 percentage-points for each estimation.

The following sensitivity table presents information of the effect each 1 percentage-point change in our assumptions on our share of reserves for CAR and other residual markets could have on our assumed loss and LAE reserves and net income for the year ended December 31, 2025. In evaluating the information in the table, it should be noted that a 1 percentage-point change in our assumptions would change estimated reserves by 1 percentage-point.

Reserve Development Summary

The changes we have recorded in our reserves in the past illustrate the uncertainty of estimating reserves. Our prior year reserves decreased by $44,552, $51,894 and $47,381 during the years ended December 31, 2025, 2024, and 2023, respectively.

The following table presents a comparison of prior year development of our net reserves for losses and LAE for the years ended December 31, 2025, 2024 and 2023, respectively. Each accident year represents all claims for an annual accounting period in which loss events occurred, regardless of when the losses are actually reported, booked or paid. Our financial statements reflect the aggregate results of the current and all prior accident years.

At the end of each period, the reserves were re-estimated for all prior accident years. Our prior year reserves decreased by $44,552, $51,894, and $47,381 for the years ended 2025, 2024, and 2023, respectively. The decreases in prior year reserves in 2025 resulted from re-estimations of prior years’ ultimate loss and LAE liabilities and are primarily composed of reductions of $13,732 in our retained automobile reserves and $28,809 in our retained other than auto and homeowner’s reserves. The decreases in prior year reserves in 2024 resulted from re-estimations of prior year’s ultimate loss and LAE liabilities and are primarily composed of reductions of $12,742 in our retained automobile reserves and $29,286 in our retained other than auto and homeowner reserves. The decrease in prior year reserves during 2023 are primarily composed of reductions of $15,451 in our retained automobile reserves and $29,782 in our retained homeowners reserves. It is not appropriate to extrapolate future favorable or unfavorable development of reserves from this past experience.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with our accompanying consolidated financial statements and notes thereto, which appear elsewhere in this document. In this discussion, all dollar amounts are presented in thousands, except share and per share data.

The following discussion contains forward-looking statements. We intend statements which are not historical in nature to be, and are hereby identified as “forward-looking statements” to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. In addition, the Company’s senior management may make forward-looking statements orally to analysts, investors, the media and others. This safe harbor requires that we specify important factors that could cause actual results to differ materially from those contained in forward-looking statements made by or on behalf of us. We cannot promise that our expectations in such forward-looking statements will turn out to be correct. Our actual results could be materially different from and worse than our expectations. See “Forward-Looking Statements” below for specific important factors that could cause actual results to differ materially from those contained in forward-looking statements.

Executive Summary and Overview

In this discussion, “Safety” refers to Safety Insurance Group, Inc. and “our Company,” “we,” “us” and “our” refer to Safety Insurance Group, Inc. and its consolidated subsidiaries. Our subsidiaries consist of Safety Insurance Company (“Safety Insurance”), Safety Indemnity Insurance Company (“Safety Indemnity”), Safety Property and Casualty Insurance Company (“Safety P&C”), Safety Northeast Insurance Company (“Safety Northeast”), Safety Northeast Insurance Agency, Inc. (“SNIA”), and Safety Management Corporation (“SMC”), which is SNIA’s holding company.

We are a leading provider of private passenger automobile (55.8% of our direct written premiums in 2024), commercial automobile, (15.2% of 2024 direct written premiums), and homeowners (24.3% of 2024 direct written premiums) insurance. In addition to these coverages, we offer a portfolio of other insurance products, including dwelling fire, umbrella and business owner policies (totaling 4.7% of 2024 direct written premiums).  Operating exclusively in Massachusetts, New Hampshire and Maine through our insurance company subsidiaries, Safety Insurance, Safety Indemnity, Safety P&C, and Safety Northeast (together referred to as the “Insurance Subsidiaries”), we have established strong relationships with independent insurance agents, who numbered 828 in 1,079 locations throughout these three states during 2024. We have used these relationships and our extensive knowledge of the market to become the third largest private passenger automobile carrier and the second largest commercial automobile carrier in Massachusetts, capturing an approximate 9.7% and 12.9% share, respectively, of the Massachusetts private passenger and commercial automobile markets in 2024, according to statistics compiled by the Commonwealth Automobile Reinsurers (“CAR”) based on automobile exposures. We are the third largest homeowners insurance carrier in Massachusetts, with a market share of 6.3% in 2023.

A.M. Best, which rates insurance companies based on factors of concern to policyholders, currently assigns Safety Insurance an “A (Excellent)” rating. Our “A” rating was reaffirmed by A.M. Best on June 18, 2024.

Our Insurance Subsidiaries began writing insurance in New Hampshire during 2008 and Maine in 2016. In November 2020, we formed a fourth insurance subsidiary, Safety Northeast, which became licensed to write insurance products in Massachusetts. The table below shows the amount of direct written premiums in each state during the years ended December 31, 2024, 2023, and 2022.

Recent Trends and Events

Direct and Net Written Premiums. For the quarter ended December 31, 2024, the Company achieved its ninth consecutive quarter of double-digit growth in direct and net written premiums. For the three months ended December 31, 2024, direct written premium growth and net written premium growth were 18.7% and 12.9%, respectively. For the year ended December 31, 2024, direct written premium growth and net written premium growth were 20.4% and 18.2%, respectively. The increase in premium is driven by new business production, improved retention, and rate increases. For the year ended December 31, 2024, the Company achieved policy count growth across all lines of business, including 10.0%, 4.5% and 8.7% in Private Passenger Automobile, Commercial Automobile and Homeowners lines, respectively, compared to the same period in 2023. Additionally, for the year ended December 31, 2024, average written premium per policy increased 14.1%, 10.7% and 8.9% in Private Passenger Automobile, Commercial Automobile and Homeowners lines, respectively, compared to the same period in 2023.

The following rate changes have been filed and approved by the insurance regulators of Massachusetts, New Hampshire and Maine in 2025, 2024 and 2023.

Losses and Loss Adjustment Expenses. Losses and loss adjustment expenses incurred for the three months ended December 31, 2024 increased by $20,902, or 12.1%, to $193,007 from $172,105 for the comparable 2023 period. Losses and loss adjustment expenses incurred for the year ended December 31, 2024 increased by $74,335, or 11.6%, to $716,637 from $642,302 for the comparable 2023 period. The increase in losses for the three months ended and year ended December 31, 2024 is primarily driven by larger policy counts.

Loss, expense, and combined ratios calculated under U.S. generally accepted accounting principles for the quarter ended December 31, 2024 were 71.7%, 30.2%, and 101.9%, respectively, compared to 76.1%, 30.4%, and 106.5%, respectively, for the comparable 2023 period. Loss, expense, and combined ratios calculated under U.S. generally accepted accounting principles for the year ended December 31, 2024 were 70.9%, 30.2%, and 101.1%, respectively, compared to 77.0%, 30.7%, and 107.7%, respectively, for the comparable 2023 period. The 2024 decrease

40

Table of Contents

in loss ratio is primarily due to the moderation of loss severity in Private Passenger Automobile, growth in earned premiums, and favorable prior year development. Additionally, the prior year loss ratio for the year ended December 31, 2023 was impacted by two severe weather events, totaling $41,178. The 2024 decrease in the expense ratios in both periods is primarily driven by the increase in net earned premium.

We define a “catastrophe” as an event that produces pre-tax losses before reinsurance in excess of $1,000 and involves multiple first-party policyholders, or an event that produces a number of claims in excess of a preset, per-event threshold of average claims in a specific area, occurring within a certain amount of time following the event. Catastrophes are caused by various natural events including high winds, winter storms, tornadoes, hailstorms, and hurricanes. The nature and level of catastrophes in any period cannot be reliably predicted.

Catastrophe losses incurred by the type of event are shown in the following table.

Statutory Accounting Principles

Our results are reported in accordance with generally accepted accounting principles (“GAAP”), which differ from amounts reported in accordance with statutory accounting principles ("SAP") as prescribed by insurance regulatory authorities, which in general reflect a liquidating, rather than going concern concept of accounting. Specifically, under GAAP:

Column 1Column 2Column 3
Policy acquisition costs such as commissions, premium taxes and other variable costs incurred which are directly related to the successful acquisition of a new or renewal insurance contract are capitalized and amortized on a pro rata basis over the period in which the related premiums are earned, rather than expensed as incurred, as required by SAP.

Column 1Column 2Column 3
Certain assets are included in the consolidated balance sheets whereas, under SAP, such assets are designated as "nonadmitted assets," and charged directly against statutory surplus. These assets consist primarily of premium receivables that are outstanding over ninety days, federal deferred tax assets in excess of statutory limitations, furniture, equipment, leasehold improvements and prepaid expenses.

Column 1Column 2Column 3
Amounts related to ceded reinsurance are shown gross of ceded unearned premiums and reinsurance recoverables, rather than netted against unearned premium reserves and loss and loss adjustment expense reserves, respectively, as required by SAP.

Column 1Column 2Column 3
Fixed maturities securities, which are classified as available-for-sale, are reported at current fair values, rather than at amortized cost, or the lower of amortized cost or market, depending on the specific type of security, as required by SAP.

Column 1Column 2Column 3
The differing treatment of income and expense items results in a corresponding difference in federal income tax expense. Changes in deferred income taxes are reflected as an item of income tax benefit or expense, rather than recorded directly to surplus as regards policyholders, as required by SAP. Admittance testing may result in a charge to unassigned surplus for non-admitted portions of deferred tax assets. Under GAAP reporting, a valuation allowance may be recorded against the deferred tax asset and reflected as an expense.

Insurance Ratios

The property and casualty insurance industry uses the combined ratio as a measure of underwriting profitability.  The combined ratio is the sum of the loss ratio (losses and loss adjustment expenses incurred as a percent of net earned premiums) plus the expense ratio (underwriting and other expenses as a percent of net earned premiums, calculated on a GAAP basis).  The combined ratio reflects only underwriting results and does not include income from investments or finance and other service income.  Underwriting profitability is subject to significant fluctuations due to competition, catastrophic events, weather, economic and social conditions, and other factors.

Our GAAP insurance ratios are presented in the following table for the periods indicated.

Share-Based Compensation

On March 24, 2022, the Company’s Board of Directors adopted the Amended and Restated Safety Insurance Group, Inc. 2018 Long-Term Incentive Plan (the “Amended 2018 Plan”), which was subsequently approved by our shareholders at the 2022 Annual Meeting of Shareholders. The Amended 2018 Plan increases the share pool limit by adding 350,000 common shares to the previously adopted Safety Insurance Group, Inc. 2018 Long-Term Incentive Plan. The Amended 2018 Plan enables the grant of stock awards, performance shares, cash-based performance units, other stock-based awards, stock options, stock appreciation rights, and stock unit awards, each of which may be granted separately or in tandem with other awards. Eligibility to participate includes officers, directors, employees and other individuals who provide bona fide services to the Company. The Amended 2018 Plan supersedes the Company’s 2002 Management Omnibus Incentive Plan (“the 2002 Incentive Plan”).

The Amended 2018 Plan establishes a pool of 700,000 shares of common stock available for issuance to our employees and other eligible participants. The Board of Directors and the Compensation Committee intend to issue awards under the Amended 2018 Plan in the future.

The maximum number of shares of common stock between both the 2018 Amended Plan and 2002 Incentive Plan with respect to which awards may be granted is 3,200,000. No further grants will be allowed under the 2002 Incentive Plan. At December 31, 2024, there were 364,912 shares available for future grant. Grants outstanding under the plans as of December 31, 2024, were comprised of 136,754 restricted shares.

Vesting of these shares is dependent upon the attainment of pre-established performance objectives, and any difference between shares granted and shares earned at the end of the performance period will be reported at the conclusion of the performance period.

(4) The shares represent a true-up of previously awarded performance-based restricted share awards. The updated shares were calculated based on the attainment of pre-established performance objectives and granted under the Amended 2018 Plan.

Reinsurance

We reinsure with other insurance companies a portion of our potential liability under the policies we have underwritten, thereby protecting us against an unexpectedly large loss or a catastrophic occurrence that could produce large losses, primarily in our homeowners line of business. We use various software products to measure our exposure to catastrophe losses and the probable maximum loss to us for catastrophe losses such as hurricanes. The reinsurance market has seen from the various software modelers, increases in the estimate of damage from hurricanes in the southern and northeast portions of the United States due to revised estimations of increased hurricane activity and increases in the estimation of demand surge in the periods following a significant event. We continue to manage and model our exposure and adjust our reinsurance programs as a result of the changes to the models. As of January 1, 2024, we purchased three layers of excess catastrophe reinsurance providing $615,000 of coverage for property losses in excess of $75,000 up to a maximum of $690,000. Our reinsurers’ co-participation is 80.0% of $75,000 for the 1st layer, 80.0% of $250,000 for the 2nd layer, and 80.0% of $290,000 for the 3rd layer. As a result of the changes to the models, our catastrophe reinsurance in 2024 protects us in the event of a “121-year storm” (that is, a storm of a severity expected to occur once in a 121-year period). Most of our reinsurers have an A.M. Best rating of “A+” (Superior) or “A” (Excellent).

We are a participant in CAR, a state-established body that runs the residual market reinsurance programs for commercial automobile insurance in Massachusetts under which premiums, expenses, losses and loss adjustment expenses on ceded business are shared by all insurers writing commercial automobile insurance in Massachusetts.

We also had $168,538 due from CAR comprising of loss and loss adjustment expense reserves, unearned premiums and reinsurance recoverables.

Non-GAAP Measures

Management has included certain non-generally accepted accounting principles (“non-GAAP”) financial measures in presenting the Company’s results. Management believes that these non-GAAP measures better explain the

Table of Contents

Company’s results of operations and allow for a more complete understanding of the underlying trends in the Company’s business. These measures should not be viewed as a substitute for those determined in accordance with GAAP. In addition, our definitions of these items may not be comparable to the definitions used by other companies.

Non-GAAP operating income and non-GAAP operating income per diluted share consist of our GAAP net income adjusted by the net realized gains on investments, net impairment losses on investments, changes in net unrealized gains on equity securities, credit loss benefit (expense) and taxes related thereto. Net income and earnings per diluted share are the GAAP financial measures that are most directly comparable to non-GAAP operating income and non-GAAP operating income per diluted share, respectively. A reconciliation of the GAAP financial measures to these non-GAAP measures is included in the financial highlights below.

YEAR ENDED DECEMBER 31, 2024 COMPARED TO YEAR ENDED DECEMBER 31, 2023

Direct Written Premiums.  Direct written premiums for the year ended December 31, 2024 increased by $201,833, or 20.4%, to $1,193,057 from $991,224 for the comparable 2023 period. The increase in direct written premium is the result of new business production, improved retention, and rate increases. For the year ended December 31, 2024, the Company achieved policy count growth across all lines of business, including 10.0%, 4.5% and 8.7% in Private Passenger Automobile, Commercial Automobile and Homeowners lines, respectively, compared to the same period in 2023. Additionally, for the year ended December 31, 2024, average written premium per policy increased 14.1%, 10.7% and 8.9% in Private Passenger Automobile, Commercial Automobile and Homeowners lines, respectively, compared to the same period in 2023.

Net Written Premiums.  Net written premiums for the year ended December 31, 2024 increased by $168,110, or 18.2%, to $1,093,405 from $925,295 for the comparable 2023 period. The 2024 increase was primarily due to the factors that increased direct written premiums.

Net Earned Premiums.  Net earned premiums for the year ended December 31, 2024 increased by $176,290, or 21.1%, to $1,010,704 from $834,414 for the comparable 2023 period. The 2024 increase was primarily due to the factors that increased direct written premiums.

The effect of reinsurance on net written and net earned premiums is presented in the following table.

Net Investment Income.  Net investment income for the year ended December 31, 2024 decreased by $657, or 1.2%, to $55,720 from $56,377 for the comparable 2023 period. The decrease is a result of decreases due to the earned interest from our higher yield bonds and variable rate secured and senior bank loans. Net effective annual yield on the investment portfolio was 3.9% for the year ended December 31, 2024, compared to 4.0% for comparable 2023 period. Our duration was 3.5 years at December 31, 2024, compared to 3.6 years at December 31, 2023.

Earnings from Partnership Investments. Earnings from partnership investments were $10,271 for the year ended December 31, 2024 compared to $5,540 for the year ended December 31, 2023. The 2024 earnings reflect an increase in investment appreciation and distribution of investment returns compared to the prior year. Timing and generation of these returns on capital can vary based on the results and transactions of the underlying partnerships.

Net Realized Gains on Investments.  Net realized gains on investments were $7,720 for the year ended December 31, 2024 compared to $1,327 for the comparable 2023 period. The increase is driven by higher realized gains from the sale of equity securities compared to prior years.

The gross unrealized gains and losses on investments in fixed maturity securities, including redeemable preferred stocks that have characteristics of fixed maturities, equity securities, including interests in mutual funds, and other invested assets were as follows:

The Company’s analysis of its fixed maturity portfolio at December 31, 2024 concluded that $1,198 of unrealized losses were due to credit factors and were recorded as an allowance for expected credit losses at December 31, 2024, compared to $1,208 at December 31, 2023. The Company concluded that outside of the securities that were recognized as credit impaired, the unrealized losses recorded on the fixed maturity portfolio at December 31, 2024 and 2023 resulted from fluctuations in market interest rates and other temporary market conditions as opposed to fundamental changes in the credit quality of the issuers of such securities. Based upon the analysis performed, the Company’s decision to hold these securities, the Company’s current level of liquidity and our history of positive operating cash flows, management believes it is more likely than not that it will not be required to sell any of its securities before the anticipated recovery in the fair value to its amortized cost basis.

Specific qualitative analysis was also performed for securities appearing on our “Watch List,” if any.

Qualitative analysis considered such factors as the financial condition and the near term prospects of the issuer, whether the debtor is current on its contractually obligated interest and principal payments, changes to the rating of the security by a rating agency and the historical volatility of the fair value of the security.

The majority of unrealized losses recorded on the investment portfolio at December 31, 2024 resulted from fluctuations in market interest rates and other temporary market conditions as opposed to fundamental changes in the credit quality of the issuers of such securities. Given our current level of liquidity, the fact that we do not intend to sell these securities, and that it is more likely than not that we will not be required to sell these securities prior to recovery of the cost basis of these securities, these decreases in values are viewed as being temporary.

For information regarding fair value measurements of our investment portfolio, refer to Item 8—Financial Statements and Supplementary Data, Note 16, Fair Value of Financial Instruments, of this Form 10-K.

Commission Income: Commission income includes revenues from new and renewal commissions paid by insurance carriers, which we recognize when earned. Commission income was $7,942 and $6,932 for the years ended December 31, 2024 and 2023, respectively.

Finance and Other Service Income.  Finance and other service income includes revenues from premium installment charges, which we recognize when earned, and other miscellaneous income and fees. Finance and other service income increased by $4,306, or 22.2%, to $23,700 for the year ended December 31, 2024 from $19,394 for the comparable 2023 period. The increase is primarily driven by the increase in policy counts and changes to our fee assessment policies.

Losses and Loss Adjustment Expenses.  Losses and loss adjustment expenses incurred for the year ended December 31, 2024 increased by $74,335, or 11.6%, to $716,637 from $642,302 for the comparable 2023 period.

Our GAAP loss ratio for the years ended December 31, 2024 and 2023 were 70.9% and 77.0%, respectively. Our GAAP loss ratio excluding loss adjustment expenses was 62.6% and 67.9% for the years ended December 31, 2024 and 2023, respectively. Total prior year favorable development included in the pre-tax results for the year ended December 31, 2024 was $51,894, compared to $47,381 for the comparable 2023 period.

Underwriting, Operating and Related Expenses.  Underwriting, operating and related expenses for the year ended December 31, 2024 increased by $48,742, or 19.0%, to $305,322 from $256,580 for the comparable 2023 period. The increase is driven by an increase in base commissions resulting from the increase in written premiums, offset by a decrease in contingent commission expense. Our GAAP expense ratio for the year ended December 31, 2024 decreased to 30.2% from 30.7% for the comparable 2023 period.

Other Expense: Other expense includes the operating and related expenses associated with SNIA.

Interest Expense.  Interest expense was $509 and $818 for the years ended December 31, 2024 and 2023, respectively. Interest expense primarily relates to the borrowing from the FHLB as noted within Item 8 – Financial Statements and Supplementary Data, Note 10, Debt, of this Form 10-K. The credit facility commitment fee included in interest expense was $60 and $75 for the years ended December 31, 2024 and 2023, respectively.

Income Tax Expense.  Our effective tax rates were 21.3% and 22.7% for the years ended December 31, 2024 and 2023, respectively. The effective rates for the year ended December 31, 2024 and 2023 were higher than the statutory rate primary due to the impact of stock-based and executive compensation.

The comparison of results for the year ended December 31, 2023 compared to the year ended December 31, 2022 can be found in the Company’s 2023 Annual Report on Form 10-K filed with the SEC on February 28, 2024.

Liquidity and Capital Resources

As a holding company, Safety’s assets consist primarily of the stock of our direct and indirect subsidiaries. Our principal source of funds to meet our obligations and pay dividends to shareholders, therefore, is dividends and other permitted payments from our subsidiaries, principally Safety Insurance. Safety is the borrower under our credit facility.

Safety Insurance’s sources of funds primarily include premiums received, investment income and proceeds from sales and redemptions of investments. Safety Insurance’s principal uses of cash are the payment of claims, operating expenses and taxes, the purchase of investments and payment of dividends to Safety.

Net cash provided by operating activities was $128,688, $52,114, and $44,326 during the years ended December 31, 2024, 2023, and 2022, respectively.  Our operations typically generate positive cash flows from operations as most premiums are received in advance of the time when claim and benefit payments are required. These positive operating cash flows are expected to continue to meet our liquidity requirements.

Net cash used for investing activities was $54,541 during the year ended December 31, 2024 compared to net cash provided by investing activities of $24,269 for December 31, 2023, and net cash used for investing activities of $19,988 for the year ended December 31, 2022. This fluctuation was driven by purchases exceeding proceeds from sales, paydowns, calls and maturities of fixed maturity and equity securities in 2024.

Net cash used for financing activities was $53,325, $63,531, and $62,641 during the years ended December 31, 2024, 2023 and 2022, respectively. Net cash used for financing activities during the year ended December 31, 2024 consisted of dividend payments to shareholders.

The Insurance Subsidiaries maintain a high degree of liquidity within their respective investment portfolios in fixed maturity and short-term investments. We do not anticipate the need to sell these securities to meet the Insurance Subsidiaries cash requirements. We expect the Insurance Subsidiaries to generate sufficient operating cash to meet all short-term and long-term cash requirements. However, there can be no assurance that unforeseen business needs or other items will not occur causing us to have to sell securities before their values fully recover; thereby causing us to recognize additional impairment charges in that time period.

Regulatory Matters

Our insurance company’s subsidiaries are subject to various regulatory restrictions that limit the maximum amount of dividends available to be paid to their parent without prior approval of the Commissioner. The Massachusetts statute limits the dividends an insurer may pay in any twelve-month period, without the prior permission of the Commissioner, to the greater of (i) 10% of the insurer’s surplus as of the preceding December 31 or (ii) the insurer’s net income for the twelve-month period ending the preceding December 31, in each case determined in accordance with statutory accounting practices. Our Insurance Subsidiaries may not declare an “extraordinary dividend” (defined as any dividend or distribution that, together with other distributions made within the preceding twelve months, exceeds the limits established by Massachusetts statute) until thirty days after the Commissioner has received notice of the intended dividend and has not objected. As historically administered by the Commissioner, this provision requires the Commissioner’s prior approval of an extraordinary dividend. Under Massachusetts law, an insurer may pay cash dividends only from its unassigned funds, also known as earned surplus, and the insurer’s remaining surplus must be both reasonable in relation to its outstanding liabilities and adequate to its financial needs. At year-end 2024, the statutory surplus of Safety Insurance was $758,789, and its net income for 2024 was $43,387. As a result, a maximum of $75,879 is available in 2024 for such dividends without prior approval of the Commissioner. As a result of this Massachusetts statute, the Insurance Subsidiaries had restricted net assets in the amount of $682,910 at December 31, 2024. During the twelve months ended December 31, 2024, Safety Insurance recorded dividends to Safety of $51,123.

The maximum dividend permitted by law is not indicative of an insurer’s actual ability to pay dividends, which may be constrained by business and regulatory considerations, such as the impact of dividends on surplus, which could affect an insurer’s ratings or competitive position, the amount of premiums that can be written and the ability to pay future dividends.

Since the initial public offering of its common stock in November 2002, the Company has paid regular quarterly dividends to shareholders of its common stock. Quarterly dividends paid during 2024 and 2023 were as follows:

On February 14, 2025, our Board approved and declared a quarterly cash dividend on our common stock of $0.90 per share to be paid on March 14, 2025 to shareholders of record on March 3, 2025. We plan to continue to declare and pay quarterly cash dividends in 2025, depending on our financial position and the regularity of our cash flows.

On February 23, 2022, the Board approved a share repurchase program of up to $50,000 of the Company’s outstanding common shares.  The Board of Directors had cumulatively authorized increases to the existing share repurchase program of up to $200,000 of its outstanding common shares.  Under the program, the Company may repurchase shares of its common stock for cash in public or private transactions, in the open market or otherwise.  The timing of such repurchases and actual number of shares repurchased will depend on a variety of factors including price, market conditions and applicable regulatory and corporate requirements.  The program does not require the Company to repurchase any specific number of shares and may be modified, suspended or terminated at any time without prior notice.

No share purchases were made by the Company during the year ended December 31, 2024. During the year ended December 31, 2023, the Company purchased 74,213 shares at a cost of $5,240. As of December 31, 2024 and 2023, the Company had purchased 3,215,690 shares on the open market at a cost of $155,240.

Management believes that the current level of cash flow from operations provides us with sufficient liquidity to meet our operating needs over the next 12 months. We expect to be able to continue to meet our operating needs after the next 12 months from internally generated funds. Since our ability to meet our obligations in the long term (beyond such twelve-month period) is dependent upon such factors as market changes, insurance regulatory changes and economic conditions, no assurance can be given that the available net cash flow will be sufficient to meet our operating needs. We expect that we would need to borrow or issue capital stock if we needed additional funds, for example, to pay for an acquisition or a significant expansion of our operations. There can be no assurance that sufficient funds for any of the foregoing purposes would be available to us at such time.

Contractual Obligations

We have obligations to make future payments under contracts and credit-related financial instruments and commitments.

As of December 31, 2024, the Company had loss and LAE reserves of $671,669, unpaid reinsurance recoverables of $130,792 and net loss and LAE reserves of $540,877. Our loss and LAE reserves are estimates as described in more detail under Critical Accounting Policies and Estimates. The specific amounts and timing of obligations related to case reserves, IBNR reserves and related LAE reserves are not set contractually, and the amounts and timing of these obligations are unknown. While management believes that historical performance of loss payment patterns is a reasonable source for projecting future claims payments, there is inherent uncertainty in this estimated projected settlement of loss and LAE reserves, and as a result these estimates will differ, perhaps significantly, from actual future payments.

As part of the Company’s investment activity, we have committed $170,000 to investments in limited partnerships.  The Company has contributed $144,682 to these commitments as of December 31, 2024.  As of December 31, 2024, the remaining committed capital that could be called is $34,033, which includes potential recallable capital distributions.

Critical Accounting Policies and Estimates

Loss and Loss Adjustment Expense Reserves

Significant periods of time can elapse between the occurrence of an insured loss, the reporting to us of that loss and our final payment of that loss. To recognize liabilities for unpaid losses, we establish reserves as balance sheet liabilities. Our reserves represent estimates of amounts needed to pay reported and estimated losses incurred but not yet reported (“IBNR”) and the expenses of investigating and paying those losses, or loss adjustment expenses. Every quarter, we review our previously established reserves and adjust them, if necessary.

When a claim is reported, claims personnel establish a “case reserve” for the estimated amount of the ultimate payment. The amount of the reserve is primarily based upon an evaluation of the type of claim involved, the circumstances surrounding each claim and the policy provisions relating to the loss. The estimate reflects the informed

50

Table of Contents

judgment of such personnel based on general insurance reserving practices and on the experience and knowledge of the claims professional. During the loss adjustment period, these estimates are revised as deemed necessary by our claims department based on subsequent developments and periodic reviews of the cases. When a claim is closed with or without a payment, the difference between the case reserve and the settlement amount creates a reserve deficiency if the payment exceeds the case reserve or a reserve redundancy if the payment is less than the case reserve.

In accordance with industry practice, we also maintain reserves for IBNR. IBNR reserves are determined in accordance with commonly accepted actuarial reserving techniques on the basis of our historical information and experience. We review and make adjustments to incurred but not yet reported reserves quarterly. In addition, IBNR reserves can also be expressed as the total loss reserves required less the case reserves on reported claims.

When reviewing reserves, we analyze historical data and estimate the impact of various loss development factors, such as our historical loss experience and that of the industry, trends in claims frequency and severity, our mix of business, our claims processing procedures, legislative enactments, judicial decisions, legal developments in imposition of damages, and changes and trends in general economic conditions, including the effects of inflation. A change in any of these factors from the assumption implicit in our estimate can cause our actual loss experience to be better or worse than our reserves, and the difference can be material. There is no precise method, however, for evaluating the impact of any specific factor on the adequacy of reserves, because the eventual development of reserves is affected by many factors.

In estimating all our loss reserves, we follow the guidance prescribed by ASC 944, Financial Services – Insurance.

Management determines our loss and loss adjustment expense reserves estimate based upon the analysis of our actuaries. A reasonable estimate is derived by selecting a point estimate within a range of indications as calculated by our actuaries using generally accepted actuarial techniques. The key assumption in most actuarial analysis is that past patterns of frequency and severity will repeat in the future, unless a significant change in the factors described above takes place. Our key factors and resulting assumptions are the ultimate frequency and severity of claims, based upon the most recent ten years of claims reported to the Company, and the data CAR reports to us to calculate our share of the residual market, as of the date of the applicable balance sheet. For each accident year and each coverage within a line of business our actuaries calculate the ultimate losses incurred. Our total reserves are the difference between the ultimate losses incurred and the cumulative loss and loss adjustment payments made to date. Our IBNR reserves are calculated as the difference between our total reserves and the outstanding case reserves at the end of the accounting period. To determine ultimate losses, our actuaries calculate a range of indications and select a point estimation using such actuarial techniques as:

Column 1Column 2Column 3
Paid Loss Indications: This method projects ultimate loss estimates based upon extrapolations of historic paid loss trends. This method tends to be used on short tail lines such as automobile physical damage.
Column 1Column 2Column 3
Incurred Loss Indications: This method projects ultimate loss estimates based upon extrapolations of historic incurred loss trends. This method tends to be used on long tail lines of business such as automobile liability and homeowner’s liability.
Column 1Column 2Column 3
Bornhuetter-Ferguson Indications: This method projects ultimate loss estimates based upon extrapolations of an expected amount of IBNR, which is added to current incurred losses or paid losses. This method tends to be used on small, immature, or volatile lines of business, such as our BOP and umbrella lines of business.
Column 1Column 2Column 3
Bodily Injury Code Indications: This method projects ultimate loss estimates for our private passenger and commercial automobile bodily injury coverage based upon extrapolations of the historic number of accidents and the historic number of bodily injury claims per accident. Projected ultimate bodily injury claims are then segregated into expected claims by type of injury (e.g. soft tissue injury vs. hard tissue injury) based on past experience. An ultimate severity, or average paid loss amounts, is estimated based upon extrapolating historic trends. Projected ultimate loss estimates using this method are the aggregate of estimated losses by injury type.

Such techniques assume that past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate basis for predicting our ultimate losses, total reserves and resulting IBNR reserves. It is possible that the final outcome may fall above or below these amounts as a result of a number of factors, including immature data, sparse data, or significant growth in a line of business. Using these methodologies our actuaries established a range of reasonably possible estimations for net reserves of approximately $497,512 to $566,772 as of December 31, 2024 compared to a range of $449,272 to $511,724 as of December 31, 2023. In general, the low and high values of the ranges represent reasonable minimum and maximum values of the indications based on the techniques described above. Our selected point estimate of net loss and loss adjustment expense reserves based upon the analysis of our actuaries was $540,877 as of December 31, 2024 compared to $490,458 as of December 31, 2023.

Residual Market Loss and Loss Adjustment Expense Reserves

We are a participant in CAR and other various residual markets and assume a portion of losses and LAE on business ceded by the industry participants to the residual markets. We were a participant in the FAIR Plan until the recent FAIR Plan Restructuring.  We estimate reserves for assumed losses and LAE that have not yet been reported to us by the residual markets.  Our estimations are based upon the same factors we use for our own reserves, plus additional factors due to the nature of and the information we receive.

Residual market deficits consist of premium ceded to the various residual markets less losses and LAE and is allocated among insurance companies based on a various formulas (the “Participation Ratio”) that take into consideration a company’s voluntary market share.

Because of the lag in the various residual market estimations, and in order to try to validate to the extent possible the information provided, we estimate the effects of the actions of our competitors in order to establish our Participation Ratio.

Although we rely to a significant extent in setting our reserves on the information the various residual markets provide, we are cautious in our use of that information, because of the delays in receiving data from the various residual markets.  As a result, we have to estimate our Participation Ratio and these reserves are subject to significant judgments and estimates.

Sensitivity Analysis

Establishment of appropriate reserves is an inherently uncertain process. There can be no certainty that currently established reserves based on our key assumptions regarding frequency and severity in our lines of business, or our assumptions regarding our share of the CAR loss will prove adequate in light of subsequent actual experience. To the extent that reserves are inadequate and are strengthened, the amount of such increase is treated as a charge to earnings in the period that the deficiency is recognized. To the extent that reserves are redundant and are released, the amount of the release is a credit to earnings in the period the redundancy is recognized.  For the twelve months ended December 31, 2024, a 1 percentage-point change in the loss and LAE ratio would result in a change in reserves of $10,110. Each 1 percentage-point change in the loss and loss expense ratio would have had a $7,987 effect on net income, or $0.54 per diluted share.

Our assumptions consider that past experience, adjusted for the effects of current developments and anticipated trends, are an appropriate basis for establishing our reserves. Our individual key assumptions could each have a reasonable possible range of plus or minus 5 percentage-points for each estimation, although there is no guarantee that our assumptions will not have more than a 5 percentage point variation.  The following sensitivity tables present information for each of our primary lines of business on the effect each 1 percentage-point change in each of our key assumptions on unpaid frequency and severity could have on our retained (i.e., direct minus ceded) loss and LAE reserves and net income for the twelve months ended December 31, 2024. In evaluating the information in the table, it should be noted that a 1 percentage-point change in a single assumption would change estimated reserves by 1

Our estimated share of CAR loss and LAE reserves is based on assumptions about our Participation Ratio, the size of CAR, and the resulting deficit.  Our assumptions consider that past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate basis for establishing our CAR reserves. Each of our assumptions could have a reasonably possible range of plus or minus 5 percentage-points for each estimation.

The following sensitivity table presents information of the effect each 1 percentage-point change in our assumptions on our share of reserves for CAR and other residual markets could have on our assumed loss and LAE reserves and net income for the year ended December 31, 2024. In evaluating the information in the table, it should be noted that a 1 percentage-point change in our assumptions would change estimated reserves by 1 percentage-point.

Reserve Development Summary

The changes we have recorded in our reserves in the past illustrate the uncertainty of estimating reserves. Our prior year reserves decreased by $51,894, $47,381 and $57,279 during the years ended December 31, 2024, 2023, and 2022, respectively.

The following table presents a comparison of prior year development of our net reserves for losses and LAE for the years ended December 31, 2024, 2023 and 2022, respectively. Each accident year represents all claims for an annual accounting period in which loss events occurred, regardless of when the losses are actually reported, booked or paid.  Our financial statements reflect the aggregate results of the current and all prior accident years.

At the end of each period, the reserves were re-estimated for all prior accident years. Our prior year reserves decreased by $51,894, $47,381, and $57,279 for the years ended 2024, 2023, and 2022, respectively. The decreases in prior year reserves in 2024 resulted from re-estimations of prior years’ ultimate loss and LAE liabilities and are primarily composed of reductions of $12,742 in our retained automobile reserves and $29,286 in our retained other than auto and homeowner’s reserves. The decreases in prior year reserves in 2023 resulted from re-estimations of prior year’s ultimate loss and LAE liabilities and are primarily composed of reductions of $15,451 in our retained automobile reserves and $29,782 in our retained other than auto and homeowner reserves. The decrease in prior year reserves during 2022 are primarily composed of reductions of $20,241 in our retained automobile reserves and $32,963 in our retained homeowners reserves. It is not appropriate to extrapolate future favorable or unfavorable development of reserves from this past experience.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with our accompanying consolidated financial statements and notes thereto, which appear elsewhere in this document. In this discussion, all dollar amounts are presented in thousands, except share and per share data.

The following discussion contains forward-looking statements. We intend statements which are not historical in nature to be, and are hereby identified as “forward-looking statements” to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. In addition, the Company’s senior management may make forward-looking statements orally to analysts, investors, the media and others. This safe harbor requires that we specify important factors that could cause actual results to differ materially from those contained in forward-looking statements made by or on behalf of us. We cannot promise that our expectations in such forward-looking statements will turn out to be correct. Our actual results could be materially different from and worse than our expectations. See “Forward-Looking Statements” below for specific important factors that could cause actual results to differ materially from those contained in forward-looking statements.

Executive Summary and Overview

In this discussion, “Safety” refers to Safety Insurance Group, Inc. and “our Company,” “we,” “us” and “our” refer to Safety Insurance Group, Inc. and its consolidated subsidiaries. Our subsidiaries consist of Safety Insurance Company (“Safety Insurance”), Safety Indemnity Insurance Company (“Safety Indemnity”), Safety Property and Casualty Insurance Company (“Safety P&C”), Safety Northeast Insurance Company (“Safety Northeast”), Safety Northeast Insurance Agency, Inc. (“SNIA”), and Safety Management Corporation (“SMC”), which is SNIA’s holding company.

We are a leading provider of private passenger automobile (54.7% of our direct written premiums in 2023), commercial automobile, (15.9% of 2023 direct written premiums), and homeowners (24.5% of 2023 direct written premiums) insurance. In addition to these coverages, we offer a portfolio of other insurance products, including dwelling fire, umbrella and business owner policies (totaling 4.9% of 2023 direct written premiums).  Operating exclusively in Massachusetts, New Hampshire and Maine through our insurance company subsidiaries, Safety Insurance, Safety Indemnity, Safety P&C, and Safety Northeast (together referred to as the “Insurance Subsidiaries”), we have established strong relationships with independent insurance agents, who numbered 834 in 1,090 locations throughout these three states during 2023. We have used these relationships and our extensive knowledge of the market to become the third largest private passenger automobile carrier and the second largest commercial automobile carrier in Massachusetts, capturing an approximate 8.7% and 12.7% share, respectively, of the Massachusetts private passenger and commercial automobile markets in 2023, according to statistics compiled by the Commonwealth Automobile Reinsurers (“CAR”) based on automobile exposures. We are the fourth largest homeowners insurance carrier in Massachusetts, with a market share of 6.2% in 2022.

A.M. Best, which rates insurance companies based on factors of concern to policyholders, currently assigns Safety Insurance an “A (Excellent)” rating. Our “A” rating was reaffirmed by A.M. Best on June 15, 2023.

Our Insurance Subsidiaries began writing insurance in New Hampshire during 2008 and Maine in 2016. In November 2020, we formed a fourth insurance subsidiary, Safety Northeast, which became licensed to write insurance products in Massachusetts. The table below shows the amount of direct written premiums in each state during the years ended December 31, 2023, 2022, and 2021.

Recent Events

Beginning on February 2, 2023 and through February 5, 2023, the Northeast region experienced a severe winter weather event (“February Winter Freeze”) over a thirty-six hour period, whereby temperatures reached lows of negative 40 degrees Fahrenheit, including windchill. As a result of the February Winter Freeze, the Company received approximately 800 claims totaling $29,543 of losses and loss adjustment expenses for the year ended December 31, 2023.

On the morning of December 18, 2023, the Northeast region experienced a severe weather event (“December Wind Storm”) comprising heavy rain and hurricane-strength winds. This event broke forty-five-year-old wind gust records, with wind gusts reaching 90 miles per hour. As a result of the December Wind Event, the Company received approximately 1,000 claims totaling $11,635 of losses and loss adjustment expenses for the year ended December 31, 2023.

Losses and Loss Adjustment Expenses

Losses and loss adjustment expenses incurred for the three months ended December 31, 2023 increased by $40,076, or 30.4%, to $172,105 from $132,029 for the comparable 2022 period. Losses and loss adjustment expenses incurred for the year ended December 31, 2023 increased by $150,323, or 30.6%, to $642,302 from $491,979 for the comparable 2022 period. The increase in losses for the three months ended December 31, 2023 is due to continued inflationary impacts on our Private Passenger Automobile line of business and the December Wind Storm. The increase in losses for the year ended December 31, 2023 also included the February Winter Freeze and increased total automobile losses due to multiple flood events, and a separate high wind event that impacted our Homeowners line of business.

Loss, expense, and combined ratios calculated under U.S. generally accepted accounting principles for the quarter ended December 31, 2023 were 76.1%, 30.4%, and 106.5%, respectively, compared to 68.4%, 32.3%, and 100.7%, respectively, for the comparable 2022 period. Loss, expense, and combined ratios calculated under U.S. generally accepted accounting principles for the year ended December 31, 2023 were 77.0%, 30.7%, and 107.7%, respectively, compared to 64.9%, 32.3%, and 97.2%, respectively, for the comparable 2022 period. The 2023 increase in loss ratio is primarily due to the factors that increased losses and loss adjustment expenses. The 2023 decrease in the expense ratios in both periods is primarily driven by a decrease in contingent commission expense.

We define a “catastrophe” as an event that produces pre-tax losses before reinsurance in excess of $1,000 and involves multiple first-party policyholders, or an event that produces a number of claims in excess of a preset, per-event threshold of average claims in a specific area, occurring within a certain amount of time following the event. Catastrophes are caused by various natural events including high winds, winter storms, tornadoes, hailstorms, and hurricanes. The nature and level of catastrophes in any period cannot be reliably predicted.

Direct and Net Written Premiums

For the quarter ended December 31, 2023, the Company achieved its fifth consecutive quarter of double-digit growth in direct and net written premiums. For the three months ended December 31, 2023, direct written premium growth and net written premium growth were 22.2% and 20.7%, respectively. For the year ended December 31, 2023, direct written premium growth and net written premium growth were 20.4% and 19.6%, respectively. The increase in premium is driven by new business production, improved retention, and rate increases. For the year ended December 31, 2023, the Company achieved exposure count growth across all lines of business, including 14.7%, 5.4% and 11.2% in Private Passenger Automobile, Commercial Automobile and Homeowners lines, respectively, compared to the same period in 2022. Additionally, for the year ended December 31, 2023, average written premium per exposure increased 10.8%, 3.8% and 4.5% in Private Passenger Automobile, Commercial Automobile and Homeowners lines, respectively, compared to the same period in 2022.

Statutory Accounting Principles

Our results are reported in accordance with generally accepted accounting principles (“GAAP”), which differ from amounts reported in accordance with statutory accounting principles ("SAP") as prescribed by insurance regulatory authorities, which in general reflect a liquidating, rather than going concern concept of accounting. Specifically, under GAAP:

Column 1Column 2Column 3
Policy acquisition costs such as commissions, premium taxes and other variable costs incurred which are directly related to the successful acquisition of a new or renewal insurance contract are capitalized and amortized on a pro rata basis over the period in which the related premiums are earned, rather than expensed as incurred, as required by SAP.

41

Table of Contents

Column 1Column 2Column 3
Certain assets are included in the consolidated balance sheets whereas, under SAP, such assets are designated as "nonadmitted assets," and charged directly against statutory surplus. These assets consist primarily of premium receivables that are outstanding over ninety days, federal deferred tax assets in excess of statutory limitations, furniture, equipment, leasehold improvements and prepaid expenses.

Column 1Column 2Column 3
Amounts related to ceded reinsurance are shown gross of ceded unearned premiums and reinsurance recoverables, rather than netted against unearned premium reserves and loss and loss adjustment expense reserves, respectively, as required by SAP.

Column 1Column 2Column 3
Fixed maturities securities, which are classified as available-for-sale, are reported at current fair values, rather than at amortized cost, or the lower of amortized cost or market, depending on the specific type of security, as required by SAP.

Column 1Column 2Column 3
The differing treatment of income and expense items results in a corresponding difference in federal income tax expense. Changes in deferred income taxes are reflected as an item of income tax benefit or expense, rather than recorded directly to surplus as regards policyholders, as required by SAP. Admittance testing may result in a charge to unassigned surplus for non-admitted portions of deferred tax assets. Under GAAP reporting, a valuation allowance may be recorded against the deferred tax asset and reflected as an expense.

Insurance Ratios

The property and casualty insurance industry uses the combined ratio as a measure of underwriting profitability.  The combined ratio is the sum of the loss ratio (losses and loss adjustment expenses incurred as a percent of net earned premiums) plus the expense ratio (underwriting and other expenses as a percent of net earned premiums, calculated on a GAAP basis).  The combined ratio reflects only underwriting results and does not include income from investments or finance and other service income.  Underwriting profitability is subject to significant fluctuations due to competition, catastrophic events, weather, economic and social conditions, and other factors.

Our GAAP insurance ratios are presented in the following table for the periods indicated.

Share-Based Compensation

On March 24, 2022, the Company’s Board of Directors adopted the Amended and Restated Safety Insurance Group, Inc. 2018 Long-Term Incentive Plan (the “Amended 2018 Plan”), which was subsequently approved by our shareholders at the 2022 Annual Meeting of Shareholders. The Amended 2018 Plan increases the share pool limit by adding 350,000 common shares to the previously adopted Safety Insurance Group, Inc. 2018 Long-Term Incentive Plan. The Amended 2018 Plan enables the grant of stock awards, performance shares, cash-based performance units, other stock-based awards, stock options, stock appreciation rights, and stock unit awards, each of which may be granted separately or in tandem with other awards. Eligibility to participate includes officers, directors, employees and other individuals who provide bona fide services to the Company. The Amended 2018 Plan supersedes the Company’s 2002 Management Omnibus Incentive Plan (“the 2002 Incentive Plan”).

The Amended 2018 Plan establishes a pool of 700,000 shares of common stock available for issuance to our employees and other eligible participants. The Board of Directors and the Compensation Committee intend to issue awards under the Amended 2018 Plan in the future.

The maximum number of shares of common stock between both the 2018 Amended Plan and 2002 Incentive Plan with respect to which awards may be granted is 3,200,000. No further grants will be allowed under the 2002 Incentive Plan. At December 31, 2023, there were 373,422 shares available for future grant. Grants outstanding under the plans as of December 31, 2023, were comprised of 145,920 restricted shares.

(1)  The fair value per share of the restricted stock grant is equal to the closing price of our common stock on the grant date.

(2) Board of Director members must maintain stock ownership equal to at least four times their annual cash retainer. This requirement must be met within five years of becoming a director.

(3) The shares represent performance-based restricted shares award. Vesting of these shares is dependent upon the attainment of pre-established performance objectives, and any difference between shares granted and shares earned at the end of the performance period will be reported at the conclusion of the performance period.

(4) The shares represent a true-up of previously awarded performance-based restricted share awards. The updated shares were calculated based on the attainment of pre-established performance objectives and granted under the Amended 2018 Plan.

Reinsurance

We reinsure with other insurance companies a portion of our potential liability under the policies we have underwritten, thereby protecting us against an unexpectedly large loss or a catastrophic occurrence that could produce large losses, primarily in our homeowners line of business. We use various software products to measure our exposure to catastrophe losses and the probable maximum loss to us for catastrophe losses such as hurricanes. The models include estimates for our share of the catastrophe losses generated in the residual market for property insurance by the FAIR Plan. The reinsurance market has seen from the various software modelers, increases in the estimate of damage from hurricanes in the southern and northeast portions of the United States due to revised estimations of increased hurricane activity and increases in the estimation of demand surge in the periods following a significant event. We continue to manage and model our exposure and adjust our reinsurance programs as a result of the changes to the models. As of January 1, 2023, we purchased three layers of excess catastrophe reinsurance providing $590,000 of coverage for property losses in excess of $75,000 up to a maximum of $665,000. Our reinsurers’ co-participation is 75.0% of $75,000 for the 1st layer, 75.0% of $250,000 for the 2nd layer, and 75.0% of $265,000 for the 3rd layer. As a result of the changes to the models, our catastrophe reinsurance in 2023 protects us in the event of a “121-year storm” (that is, a storm of a severity expected to occur once in a 121-year period). Most of our reinsurers have an A.M. Best rating of “A+” (Superior) or “A” (Excellent).

We are a participant in CAR, a state-established body that runs the residual market reinsurance programs for commercial automobile insurance in Massachusetts under which premiums, expenses, losses and loss adjustment expenses on ceded business are shared by all insurers writing commercial automobile insurance in Massachusetts. We also participate in the Massachusetts Property Insurance Underwriting Association (“FAIR Plan”), in which premiums,

43

Table of Contents

expenses, losses and loss adjustment expenses on homeowners business that cannot be placed in the voluntary market are shared by all insurers writing homeowners insurance in Massachusetts. The FAIR Plan buys reinsurance to reduce their exposure to catastrophe losses. On July 1, 2023, the FAIR Plan purchased $1,600,000 of catastrophe reinsurance for property losses with retention of $100,000.

We also had $133,551 due from CAR comprising of loss and loss adjustment expense reserves, unearned premiums and reinsurance recoverables.

Non-GAAP Measures

Management has included certain non-generally accepted accounting principles (“non-GAAP”) financial measures in presenting the Company’s results. Management believes that these non-GAAP measures better explain the Company’s results of operations and allow for a more complete understanding of the underlying trends in the Company’s business. These measures should not be viewed as a substitute for those determined in accordance with GAAP. In addition, our definitions of these items may not be comparable to the definitions used by other companies.

Non-GAAP operating income and non-GAAP operating income per diluted share consist of our GAAP net income adjusted by the net realized gains on investments, net impairment losses on investments, changes in net unrealized gains on equity securities, credit loss benefit (expense) and taxes related thereto. Net income and earnings per diluted share are the GAAP financial measures that are most directly comparable to non-GAAP operating income and non-GAAP operating income per diluted share, respectively. A reconciliation of the GAAP financial measures to these non-GAAP measures is included in the financial highlights below.

The increase in direct written premium is the result of new business production, improved retention, and rate increases. For the year ended December 31, 2023, the Company achieved exposure count growth across all lines of business, including 14.7%, 5.4% and 11.2% in Private Passenger Automobile, Commercial Automobile and Homeowners lines, respectively, compared to the same period in 2022. Additionally, for the year ended December 31, 2023, average written premium per exposure increased 10.8%, 3.8% and 4.5% in Private Passenger Automobile, Commercial Automobile and Homeowners lines, respectively, compared to the same period in 2022.

Net Written Premiums.  Net written premiums for the year ended December 31, 2023 increased by $151,560, or 19.6%, to $925,295 from $773,735 for the comparable 2022 period. The 2023 increase was primarily due to the factors

that increased direct written premiums.

Net Earned Premiums.  Net earned premiums for the year ended December 31, 2023 increased by $75,909, or 10.0%, to $834,414 from $758,505 for the comparable 2022 period.

4.0% for the year ended December 31, 2023, compared to 3.2% for comparable 2022 period. Our duration was 3.6 years at December 31, 2023, compared to 3.8 years at December 31, 2022.

Earnings from Partnership Investments. Earnings from partnership investments were $5,540 for the year ended December 31, 2023 compared to $12,484 for the year ended December 31, 2022. The 2023 earnings reflect a decrease in investment appreciation and timing of cash proceeds received compared to the prior year. Timing and generation of these returns on capital can vary based on the results and transactions of the underlying partnerships.

Net Realized Gains on Investments.  Net realized gains on investments were $1,327 for the year ended December 31, 2023 compared to $9,190 for the comparable 2022 period.

The Company’s analysis of its fixed maturity portfolio at December 31, 2023 concluded that $1,208 of unrealized losses were due to credit factors and were recorded as an allowance for expected credit losses at December 31, 2023, compared to $678 at December 31, 2022. The Company concluded that outside of the securities that were recognized as credit impaired, the unrealized losses recorded on the fixed maturity portfolio at December 31, 2023 and 2022 resulted from fluctuations in market interest rates and other temporary market conditions as opposed to fundamental changes in the credit quality of the issuers of such securities. Based upon the analysis performed, the Company’s decision to hold these securities, the Company’s current level of liquidity and our history of positive operating cash flows, management believes it is more likely than not that it will not be required to sell any of its securities before the anticipated recovery in the fair value to its amortized cost basis.

Specific qualitative analysis was also performed for securities appearing on our “Watch List,” if any.

Qualitative analysis considered such factors as the financial condition and the near term prospects of the issuer, whether the debtor is current on its contractually obligated interest and principal payments, changes to the rating of the security by a rating agency and the historical volatility of the fair value of the security.

The majority of unrealized losses recorded on the investment portfolio at December 31, 2023 resulted from fluctuations in market interest rates and other temporary market conditions as opposed to fundamental changes in the credit quality of the issuers of such securities. Given our current level of liquidity, the fact that we do not intend to sell these securities, and that it is more likely than not that we will not be required to sell these securities prior to recovery of the cost basis of these securities, these decreases in values are viewed as being temporary.

For information regarding fair value measurements of our investment portfolio, refer to Item 8—Financial Statements and Supplementary Data, Note 16, Fair Value of Financial Instruments, of this Form 10-K.

Commission Income: Commission income includes revenues from new and renewal commissions paid by insurance carriers, which we recognize when earned. Commission Income was $6,932 and $566 for the years ended December 31, 2023 and 2022, respectively.

Finance and Other Service Income.  Finance and other service income includes revenues from premium

installment charges, which we recognize when earned, and other miscellaneous income and fees. Finance and other service income increased by $4,933, or 34.1%, to $19,394 for the year ended December 31, 2023 from $14,461 for the comparable 2022 period. The increase is primarily driven by the increase in policy counts and changes to our fee assessment policies.

Losses and Loss Adjustment Expenses.  Losses and loss adjustment expenses incurred for the year ended December 31, 2023 increased by $150,323, or 30.6%, to $642,302 from $491,979 for the comparable 2022 period. The increase in losses is due to continued inflationary impacts on our Private Passenger Automobile line of business, and impacts from weather related events including February Winter Freeze and December Wind Storm.

Our GAAP loss ratio for the years ended December 31, 2023 and 2022 were 77.0% and 64.9%, respectively. Our GAAP loss ratio excluding loss adjustment expenses was 67.9% and 56.0% for the years ended December 31, 2023 and 2022, respectively. Total prior year favorable development included in the pre-tax results for the year ended December 31, 2023 was $47,381, compared to $57,279, for the comparable 2022 period. Prior year favorable development in 2022 benefitted from the reversal of $6,500 legal expense reserve during the second quarter of 2022.

Underwriting, Operating and Related Expenses.  Underwriting, operating and related expenses for the year ended December 31, 2023 increased by $11,435, or 4.7%, to $256,580 from $245,145 for the comparable 2022 period. The increase is driven by an increase in base commissions resulting from the increase in written premiums, offset by a decrease in contingent commission expense. Our GAAP expense ratio for the year ended December 31, 2023 decreased to 30.7% from 32.3% for the comparable 2022 period.

Other Expense: Other expense includes the operating and related expenses associated with SNIA.

Interest Expense.  Interest expense was $818 and $524 for the years ended December 31, 2023 and 2022, respectively. Interest expense primarily relates to the borrowing from the FHLB as noted within Item 8 – Financial Statements and Supplementary Data, Note 10, Debt, of this Form 10-K. The credit facility commitment fee included in interest expense was $75 for each of the years ended December 31, 2023 and 2022.

Income Tax Expense.  Our effective tax rates were 22.7% and 21.9% for the years ended December 31, 2023 and 2022, respectively. The effective rates for the year ended December 31, 2023 and 2022 were higher than the statutory rate primary due to the impact of stock-based and executive compensation.

The comparison of results for the year ended December 31, 2022 compared to the year ended December 31, 2021 can be found in the Company’s 2022 Annual Report on Form 10-K filed with the SEC on February 28, 2023.

Liquidity and Capital Resources

As a holding company, Safety’s assets consist primarily of the stock of our direct and indirect subsidiaries. Our principal source of funds to meet our obligations and pay dividends to shareholders, therefore, is dividends and other permitted payments from our subsidiaries, principally Safety Insurance. Safety is the borrower under our credit facility.

Safety Insurance’s sources of funds primarily include premiums received, investment income and proceeds from sales and redemptions of investments. Safety Insurance’s principal uses of cash are the payment of claims, operating expenses and taxes, the purchase of investments and payment of dividends to Safety.

Net cash provided by operating activities was $52,114, $44,326, and $141,394 during the years ended December 31, 2023, 2022, and 2021, respectively.  Our operations typically generate positive cash flows from operations as most premiums are received in advance of the time when claim and benefit payments are required. These positive operating cash flows are expected to continue to meet our liquidity requirements.

Net cash provided by investing activities was $24,269 during the year ended December 31, 2023 compared to net cash used for investing activities was $19,988, and $65,989 for the years ended December 31, 2022, and 2021,

respectively, as proceeds from the sales, paydowns, calls and maturities of fixed maturity and equity securities exceeded purchases.

Net cash used for financing activities was $63,531, $62,641, and $65,571 during the years ended December 31, 2023, 2022 and 2021, respectively. Net cash used for financing activities during the year ended December 31, 2023 comprised dividend payments to shareholders and the acquisition of treasury stock.

The Insurance Subsidiaries maintain a high degree of liquidity within their respective investment portfolios in fixed maturity and short-term investments. We do not anticipate the need to sell these securities to meet the Insurance Subsidiaries cash requirements. We expect the Insurance Subsidiaries to generate sufficient operating cash to meet all short-term and long-term cash requirements. However, there can be no assurance that unforeseen business needs or other items will not occur causing us to have to sell securities before their values fully recover; thereby causing us to recognize additional impairment charges in that time period.

Regulatory Matters

Our insurance company’s subsidiaries are subject to various regulatory restrictions that limit the maximum amount of dividends available to be paid to their parent without prior approval of the Commissioner. The Massachusetts statute limits the dividends an insurer may pay in any twelve-month period, without the prior permission of the Commissioner, to the greater of (i) 10% of the insurer’s surplus as of the preceding December 31 or (ii) the insurer’s net income for the twelve-month period ending the preceding December 31, in each case determined in accordance with statutory accounting practices. Our Insurance Subsidiaries may not declare an “extraordinary dividend” (defined as any dividend or distribution that, together with other distributions made within the preceding twelve months, exceeds the limits established by Massachusetts statute) until thirty days after the Commissioner has received notice of the intended dividend and has not objected. As historically administered by the Commissioner, this provision requires the Commissioner’s prior approval of an extraordinary dividend. Under Massachusetts law, an insurer may pay cash dividends only from its unassigned funds, also known as earned surplus, and the insurer’s remaining surplus must be both reasonable in relation to its outstanding liabilities and adequate to its financial needs. At year-end 2023, the statutory surplus of Safety Insurance was $744,904, and its net loss for 2023 was $4,022. As a result, a maximum of $74,490 is available in 2023 for such dividends without prior approval of the Commissioner. As a result of this Massachusetts statute, the Insurance Subsidiaries had restricted net assets in the amount of $670,414 at December 31, 2023. During the twelve months ended December 31, 2023, Safety Insurance recorded dividends to Safety of $56,329.

The maximum dividend permitted by law is not indicative of an insurer’s actual ability to pay dividends, which may be constrained by business and regulatory considerations, such as the impact of dividends on surplus, which could affect an insurer’s ratings or competitive position, the amount of premiums that can be written and the ability to pay future dividends.

Since the initial public offering of its common stock in November 2002, the Company has paid regular quarterly dividends to shareholders of its common stock. Quarterly dividends paid during 2023 and 2022 were as follows:

On February 15, 2024, our Board approved and declared a quarterly cash dividend on our common stock of $0.90 per share to be paid on March 15, 2024 to shareholders of record on March 1, 2024. We plan to continue to declare and pay quarterly cash dividends in 2024, depending on our financial position and the regularity of our cash flows.

On February 23, 2022, the Board approved a share repurchase program of up to $50,000 of the Company’s outstanding common shares.  The Board of Directors had cumulatively authorized increases to the existing share repurchase program of up to $200,000 of its outstanding common shares.  Under the program, the Company may repurchase shares of its common stock for cash in public or private transactions, in the open market or otherwise.  The timing of such repurchases and actual number of shares repurchased will depend on a variety of factors including price, market conditions and applicable regulatory and corporate requirements.  The program does not require the Company to repurchase any specific number of shares and may be modified, suspended or terminated at any time without prior notice.

No share purchases were made by the Company during the three months ended December 31, 2023. During the year ended December 31, 2023, the Company purchased 74,213 shares at a cost of $5,240. As of December 31, 2023, the Company had purchased 3,215,690 shares on the open market at a cost $155,240. As of December 31, 2022, the Company had purchased 3,141,477 shares on the open market at a cost of $150,000.

Management believes that the current level of cash flow from operations provides us with sufficient liquidity to meet our operating needs over the next 12 months. We expect to be able to continue to meet our operating needs after the next 12 months from internally generated funds. Since our ability to meet our obligations in the long term (beyond such twelve-month period) is dependent upon such factors as market changes, insurance regulatory changes and economic conditions, no assurance can be given that the available net cash flow will be sufficient to meet our operating needs. We expect that we would need to borrow or issue capital stock if we needed additional funds, for example, to pay for an acquisition or a significant expansion of our operations. There can be no assurance that sufficient funds for any of the foregoing purposes would be available to us at such time.

Contractual Obligations

We have obligations to make future payments under contracts and credit-related financial instruments and commitments.

As of December 31, 2023, the Company had loss and LAE reserves of $603,081, unpaid reinsurance recoverables of $112,623 and net loss and LAE reserves of $490,458. Our loss and LAE reserves are estimates as described in more detail under Critical Accounting Policies and Estimates. The specific amounts and timing of obligations related to case reserves, IBNR reserves and related LAE reserves are not set contractually, and the amounts and timing of these obligations are unknown. While management believes that historical performance of loss payment patterns is a reasonable source for projecting future claims payments, there is inherent uncertainty in this estimated projected settlement of loss and LAE reserves, and as a result these estimates will differ, perhaps significantly, from actual future payments.

As part of the Company’s investment activity, we have committed $170,000 to investments in limited partnerships.  The Company has contributed $133,330 to these commitments as of December 31, 2023.  As of December 31, 2023, the remaining committed capital that could be called is $42,043, which includes potential recallable capital distributions.

Critical Accounting Policies and Estimates

Loss and Loss Adjustment Expense Reserves

Significant periods of time can elapse between the occurrence of an insured loss, the reporting to us of that loss and our final payment of that loss. To recognize liabilities for unpaid losses, we establish reserves as balance sheet liabilities. Our reserves represent estimates of amounts needed to pay reported and estimated losses incurred but not yet reported (“IBNR”) and the expenses of investigating and paying those losses, or loss adjustment expenses. Every quarter, we review our previously established reserves and adjust them, if necessary.

When a claim is reported, claims personnel establish a “case reserve” for the estimated amount of the ultimate payment. The amount of the reserve is primarily based upon an evaluation of the type of claim involved, the circumstances surrounding each claim and the policy provisions relating to the loss. The estimate reflects the informed judgment of such personnel based on general insurance reserving practices and on the experience and knowledge of the claims professional. During the loss adjustment period, these estimates are revised as deemed necessary by our claims department based on subsequent developments and periodic reviews of the cases. When a claim is closed with or without a payment, the difference between the case reserve and the settlement amount creates a reserve deficiency if the payment exceeds the case reserve or a reserve redundancy if the payment is less than the case reserve.

In accordance with industry practice, we also maintain reserves for IBNR. IBNR reserves are determined in accordance with commonly accepted actuarial reserving techniques on the basis of our historical information and experience. We review and make adjustments to incurred but not yet reported reserves quarterly. In addition, IBNR reserves can also be expressed as the total loss reserves required less the case reserves on reported claims.

When reviewing reserves, we analyze historical data and estimate the impact of various loss development factors, such as our historical loss experience and that of the industry, trends in claims frequency and severity, our mix of business, our claims processing procedures, legislative enactments, judicial decisions, legal developments in imposition of damages, and changes and trends in general economic conditions, including the effects of inflation. A change in any of these factors from the assumption implicit in our estimate can cause our actual loss experience to be better or worse than our reserves, and the difference can be material. There is no precise method, however, for evaluating the impact of any specific factor on the adequacy of reserves, because the eventual development of reserves is affected by many factors.

In estimating all our loss reserves, we follow the guidance prescribed by ASC 944, Financial Services – Insurance.

Management determines our loss and loss adjustment expense reserves estimate based upon the analysis of our actuaries. A reasonable estimate is derived by selecting a point estimate within a range of indications as calculated by our actuaries using generally accepted actuarial techniques. The key assumption in most actuarial analysis is that past patterns of frequency and severity will repeat in the future, unless a significant change in the factors described above takes place. Our key factors and resulting assumptions are the ultimate frequency and severity of claims, based upon the most recent ten years of claims reported to the Company, and the data CAR reports to us to calculate our share of the residual market, as of the date of the applicable balance sheet. For each accident year and each coverage within a line of business our actuaries calculate the ultimate losses incurred. Our total reserves are the difference between the ultimate losses incurred and the cumulative loss and loss adjustment payments made to date. Our IBNR reserves are calculated as the difference between our total reserves and the outstanding case reserves at the end of the accounting period. To determine ultimate losses, our actuaries calculate a range of indications and select a point estimation using such actuarial techniques as:

Bornhuetter-Ferguson Indications: This method projects ultimate loss estimates based upon extrapolations of an expected amount of IBNR, which is added to current incurred losses or paid losses. This method tends to be used on small, immature, or volatile lines of business, such as our BOP and umbrella lines of business.
Column 1Column 2Column 3
Bodily Injury Code Indications: This method projects ultimate loss estimates for our private passenger and commercial automobile bodily injury coverage based upon extrapolations of the historic number of accidents and the historic number of bodily injury claims per accident. Projected ultimate bodily injury claims are then segregated into expected claims by type of injury (e.g. soft tissue injury vs. hard tissue injury) based on past experience. An ultimate severity, or average paid loss amounts, is estimated based upon extrapolating historic trends. Projected ultimate loss estimates using this method are the aggregate of estimated losses by injury type.

Such techniques assume that past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate basis for predicting our ultimate losses, total reserves and resulting IBNR reserves. It is possible that the final outcome may fall above or below these amounts as a result of a number of factors, including immature data, sparse data, or significant growth in a line of business. Using these methodologies our actuaries established a range of reasonably possible estimations for net reserves of approximately $449,272 to $511,724 as of December 31, 2023 compared to a range of $423,452 to $481,902 as of December 31, 2022. In general, the low and high values of the ranges represent reasonable minimum and maximum values of the indications based on the techniques described above. Our selected point estimate of net loss and loss adjustment expense reserves based upon the analysis of our actuaries was $490,458 as of December 31, 2023 compared to $456,204 as of December 31, 2022.

At December 31, 2023 and 2022, our total IBNR reserves for our private passenger automobile line of business were comprised of $(87,456) and $(67,848) related to estimated ultimate decreases in the case reserves, including anticipated recoveries (i.e. salvage and subrogation), and $34,170 and $24,320 related to our estimation for not yet reported losses, respectively.

Our IBNR reserves consist of our estimate of the total loss reserves required less our case reserves.  The IBNR reserves for CAR assumed commercial automobile business are 64.4% of our total reserves for CAR assumed commercial automobile business as of December 31, 2023 due to the reporting delays in the information we receive from CAR, as described further in the section on Residual Market Loss and Loss Adjustment Expense Reserves.  Our IBNR reserves for FAIR Plan assumed homeowners are 57.5% of our total reserves for FAIR Plan assumed homeowners at December 31, 2023 due to similar reporting delays in the information we receive from FAIR Plan.

The following table presents information by line of business for our total net reserves and the corresponding retained (i.e. direct less ceded) reserves and assumed reserves as of December 31, 2023.

Residual Market Loss and Loss Adjustment Expense Reserves

We are a participant in CAR, the FAIR Plan and other various residual markets and assume a portion of losses and LAE on business ceded by the industry participants to the residual markets.  We estimate reserves for assumed losses and LAE that have not yet been reported to us by the residual markets.  Our estimations are based upon the same factors we use for our own reserves, plus additional factors due to the nature of and the information we receive.

Residual market deficits consist of premium ceded to the various residual markets less losses and LAE and is allocated among insurance companies based on a various formulas (the “Participation Ratio”) that take into consideration a company’s voluntary market share.

Because of the lag in the various residual market estimations, and in order to try to validate to the extent possible the information provided, we estimate the effects of the actions of our competitors in order to establish our Participation Ratio.

Although we rely to a significant extent in setting our reserves on the information the various residual markets provide, we are cautious in our use of that information, because of the delays in receiving data from the various residual markets.  As a result, we have to estimate our Participation Ratio and these reserves are subject to significant judgments and estimates.

Sensitivity Analysis

Establishment of appropriate reserves is an inherently uncertain process. There can be no certainty that currently established reserves based on our key assumptions regarding frequency and severity in our lines of business, or our assumptions regarding our share of the CAR loss will prove adequate in light of subsequent actual experience. To the extent that reserves are inadequate and are strengthened, the amount of such increase is treated as a charge to

53

Table of Contents

earnings in the period that the deficiency is recognized. To the extent that reserves are redundant and are released, the amount of the release is a credit to earnings in the period the redundancy is recognized.  For the twelve months ended December 31, 2023, a 1 percentage-point change in the loss and LAE ratio would result in a change in reserves of $8,341. Each 1 percentage-point change in the loss and loss expense ratio would have had a $6,589 effect on net income, or $0.45 per diluted share.

Our assumptions consider that past experience, adjusted for the effects of current developments and anticipated trends, are an appropriate basis for establishing our reserves. Our individual key assumptions could each have a reasonable possible range of plus or minus 5 percentage-points for each estimation, although there is no guarantee that our assumptions will not have more than a 5 percentage point variation.  The following sensitivity tables present information for each of our primary lines of business on the effect each 1 percentage-point change in each of our key assumptions on unpaid frequency and severity could have on our retained (i.e., direct minus ceded) loss and LAE reserves and net income for the twelve months ended December 31, 2023. In evaluating the information in the table, it should be noted that a 1 percentage-point change in a single assumption would change estimated reserves by 1 percentage-point.  A 1 percentage-point change in both our key assumptions would change estimated reserves within a range of plus or minus 2 percentage-points.

Our estimated share of CAR loss and LAE reserves is based on assumptions about our Participation Ratio, the size of CAR, and the resulting deficit (similar assumptions apply with respect to the FAIR Plan).  Our assumptions consider that past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate basis for establishing our CAR reserves. Each of our assumptions could have a reasonably possible range of plus or minus 5 percentage-points for each estimation.

The following sensitivity table presents information of the effect each 1 percentage-point change in our assumptions on our share of reserves for CAR and other residual markets could have on our assumed loss and LAE reserves and net income for the year ended December 31, 2023. In evaluating the information in the table, it should be noted that a 1 percentage-point change in our assumptions would change estimated reserves by 1 percentage-point.

Reserve Development Summary

The changes we have recorded in our reserves in the past illustrate the uncertainty of estimating reserves. Our prior year reserves decreased by $47,381, $57,279 and $53,673 during the years ended December 31, 2023, 2022, and 2021, respectively.

The following table presents a comparison of prior year development of our net reserves for losses and LAE for the years ended December 31, 2023, 2022 and 2021, respectively. Each accident year represents all claims for an annual accounting period in which loss events occurred, regardless of when the losses are actually reported, booked or paid.  Our financial statements reflect the aggregate results of the current and all prior accident years.

At the end of each period, the reserves were re-estimated for all prior accident years. Our prior year reserves decreased by $47,381, $57,279, and $53,673 for the years ended 2023, 2022, and 2021, respectively. The decreases in prior year reserves in 2023 resulted from re-estimations of prior year’s ultimate loss and LAE liabilities and are primarily composed of reductions of $15,451 in our retained automobile reserves and $29,782 in our retained other than auto and homeowner’s reserves. The decreases in prior year reserves in 2022 resulted from re-estimations of prior year’s ultimate loss and LAE liabilities and are primarily composed of reductions of $20,241 in our retained automobile reserves and $32,963 in our retained other than auto and homeowner reserves. The decrease in prior year reserves during 2021 are primarily composed of reductions of $22,313 in our retained automobile reserves and $26,220 in our retained homeowners reserves. It is not appropriate to extrapolate future favorable or unfavorable development of reserves from this past experience.

The improved retained private passenger and commercial automobile results were primarily due to fewer IBNR claims than previously estimated and better than previously estimated severity on our established bodily injury and property damage case reserves.  Our retained other than auto and homeowners line of business prior year reserves decreased, due primarily to fewer IBNR claims than previously estimated.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with our accompanying consolidated financial statements and notes thereto, which appear elsewhere in this document. In this discussion, all dollar amounts are presented in thousands, except share and per share data.

The following discussion contains forward-looking statements. We intend statements which are not historical in nature to be, and are hereby identified as “forward-looking statements” to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. In addition, the Company’s senior management may make forward-looking statements orally to analysts, investors, the media and others. This safe harbor requires that we specify important factors that could cause actual results to differ materially from those contained in forward-looking statements made by or on behalf of us. We cannot promise that our expectations in such forward-looking statements will turn out to be correct. Our actual results could be materially different from and worse than our expectations. See “Forward-Looking Statements” below for specific important factors that could cause actual results to differ materially from those contained in forward-looking statements.

Executive Summary and Overview

In this discussion, “Safety” refers to Safety Insurance Group, Inc. and “our Company,” “we,” “us” and “our” refer to Safety Insurance Group, Inc. and its consolidated subsidiaries. Our subsidiaries consist of Safety Insurance Company (“Safety Insurance”), Safety Indemnity Insurance Company (“Safety Indemnity”), Safety Property and Casualty Insurance Company (“Safety P&C”), Safety Northeast Insurance Company (“Safety Northeast”), Safety Northeast Insurance Agency, Inc. (“SNIA”), and Safety Management Corporation (“SMC”), which is SNIA’s holding company.

We are a leading provider of private passenger automobile (52.0% of our direct written premiums in 2022), commercial automobile, (17.4% of 2022 direct written premiums), and homeowners (25.3% of 2022 direct written premiums) insurance. In addition to these coverages, we offer a portfolio of other insurance products, including dwelling fire, umbrella and business owner policies (totaling 5.3% of 2022 direct written premiums).  Operating exclusively in Massachusetts, New Hampshire and Maine through our insurance company subsidiaries, Safety Insurance, Safety Indemnity, Safety P&C, and Safety Northeast (together referred to as the “Insurance Subsidiaries”), we have established strong relationships with independent insurance agents, who numbered 843 in 1,071 locations throughout these three states during 2022. We have used these relationships and our extensive knowledge of the market to become the fifth largest private passenger automobile carrier and the second largest commercial automobile carrier in Massachusetts, capturing an approximate 7.7% and 12.6% share, respectively, of the Massachusetts private passenger and commercial automobile markets in 2022, according to statistics compiled by the Commonwealth Automobile Reinsurers (“CAR”) based on automobile exposures. We are the third largest homeowners insurance carrier in Massachusetts, with a market share of 6.5% in 2021.

A.M. Best, which rates insurance companies based on factors of concern to policyholders, currently assigns Safety Insurance an “A (Excellent)” rating. Our “A” rating was reaffirmed by A.M. Best on May 26, 2022.

Our Insurance Subsidiaries began writing insurance in New Hampshire during 2008 and Maine in 2016. In November 2020, we formed a fourth insurance subsidiary, Safety Northeast, which became licensed to write insurance products in Massachusetts. The table below shows the amount of direct written premiums in each state during the years ended December 31, 2022, 2021, and 2020.

Recent Events

On December 1, 2022, SNIA was established when the Company acquired the assets and operations of Northeast Metrowest Insurance Agency, Inc. (“Northeast / Metrowest”), an independent insurance agency, through its wholly-owned subsidiary, SMC. Since 1989, Northeast / Metrowest had provided personal and commercial insurance to properly protect its customers by determining the best coverage to suit their unique needs. Over time, Northeast / Metrowest had grown to include over $40 million in policy premiums. SNIA will operate as a stand-alone business operation, providing personal and commercial property and casualty insurance products to customers on behalf of the Insurance Subsidiaries and third-party insurance carriers.

The Company had been named in a lawsuit alleging that the Company improperly denied coverage to commercial insureds for loss of business income resulting from the COVID-19 pandemic. Our position is that no coverage existed for this peril. As a result of the lawsuit, the Company accrued a reserve of $6,500 for legal defense costs included in the loss and loss adjustment expenses during the year ended December 31, 2021. During the year ended December 31, 2022, the claim against the Company was closed and the accrual of $6,500 was reversed.

Losses and Loss Adjustment Expenses

Losses and loss adjustment expenses incurred for the year ended December 31, 2022 increased by $30,252, or 6.6%, to $491,979 from $461,727 for the comparable 2021 period. The increase in losses is due to a return of pre-pandemic frequency in our private passenger automobile line of business and current market conditions including inflation and supply chain delays.

Loss, expense, and combined ratios calculated under U.S. generally accepted accounting principles for the quarter ended December 31, 2022 were 68.4%, 32.3%, and 100.7%, respectively, compared to 62.7%, 33.7%, and 96.4%, respectively, for the comparable 2021 period. Loss, expense, and combined ratios calculated under U.S. generally accepted accounting principles for the year ended December 31, 2022 were 64.9%, 32.3%, and 97.2%, respectively, compared to 59.6%, 33.4%, and 93.0%, respectively, for the comparable 2021 period. The 2022 decrease in the expense ratios in both periods is primarily driven by a decrease in contingent commission expense.

We define a “catastrophe” as an event that produces pre-tax losses before reinsurance in excess of $1,000 and involves multiple first-party policyholders, or an event that produces a number of claims in excess of a preset, per-event threshold of average claims in a specific area, occurring within a certain amount of time following the event. Catastrophes are caused by various natural events including high winds, winter storms, tornadoes, hailstorms, and hurricanes. The nature and level of catastrophes in any period cannot be reliably predicted.

Catastrophe losses incurred by the type of event are shown in the following table.

Statutory Accounting Principles

Our results are reported in accordance with generally accepted accounting principles (“GAAP”), which differ from amounts reported in accordance with statutory accounting principles ("SAP") as prescribed by insurance regulatory authorities, which in general reflect a liquidating, rather than going concern concept of accounting. Specifically, under GAAP:

Column 1Column 2Column 3
Policy acquisition costs such as commissions, premium taxes and other variable costs incurred which are directly related to the successful acquisition of a new or renewal insurance contract are capitalized and amortized on a pro rata basis over the period in which the related premiums are earned, rather than expensed as incurred, as required by SAP.

Column 1Column 2Column 3
Certain assets are included in the consolidated balance sheets whereas, under SAP, such assets are designated as "nonadmitted assets," and charged directly against statutory surplus. These assets consist primarily of premium receivables that are outstanding over ninety days, federal deferred tax assets in excess of statutory limitations, furniture, equipment, leasehold improvements and prepaid expenses.

Column 1Column 2Column 3
Amounts related to ceded reinsurance are shown gross of ceded unearned premiums and reinsurance recoverables, rather than netted against unearned premium reserves and loss and loss adjustment expense reserves, respectively, as required by SAP.

Column 1Column 2Column 3
Fixed maturities securities, which are classified as available-for-sale, are reported at current fair values, rather than at amortized cost, or the lower of amortized cost or market, depending on the specific type of security, as required by SAP.

Column 1Column 2Column 3
The differing treatment of income and expense items results in a corresponding difference in federal income tax expense. Changes in deferred income taxes are reflected as an item of income tax benefit or expense, rather than recorded directly to surplus as regards policyholders, as required by SAP. Admittance testing may result in a charge to unassigned surplus for non-admitted portions of deferred tax assets. Under GAAP reporting, a valuation allowance may be recorded against the deferred tax asset and reflected as an expense.

Insurance Ratios

The property and casualty insurance industry uses the combined ratio as a measure of underwriting profitability.  The combined ratio is the sum of the loss ratio (losses and loss adjustment expenses incurred as a percent of net earned premiums) plus the expense ratio (underwriting and other expenses as a percent of net earned premiums, calculated on a GAAP basis).  The combined ratio reflects only underwriting results and does not include income from

investments or finance and other service income.  Underwriting profitability is subject to significant fluctuations due to competition, catastrophic events, weather, economic and social conditions, and other factors.

Our GAAP insurance ratios are presented in the following table for the periods indicated.

Share-Based Compensation

On March 24, 2022, the Company’s Board of Directors adopted the Amended and Restated Safety Insurance Group, Inc. 2018 Long-Term Incentive Plan (the “Amended 2018 Plan”), which was subsequently approved by our shareholders at the 2022 Annual Meeting of Shareholders. The Amended 2018 Plan increases the share pool limit by adding 350,000 common shares to the previously adopted Safety Insurance Group, Inc. 2018 Long-Term Incentive Plan. The Amended 2018 Plan enables the grant of stock awards, performance shares, cash-based performance units, other stock-based awards, stock options, stock appreciation rights, and stock unit awards, each of which may be granted separately or in tandem with other awards. Eligibility to participate includes officers, directors, employees and other individuals who provide bona fide services to the Company. The Amended 2018 Plan supersedes the Company’s 2002 Management Omnibus Incentive Plan (“the 2002 Incentive Plan”).

The Amended 2018 Plan establishes a pool of 700,000 shares of common stock available for issuance to our employees and other eligible participants. The Board of Directors and the Compensation Committee intend to issue awards under the Amended 2018 Plan in the future.

The maximum number of shares of common stock between both the 2018 Amended Plan and 2002 Incentive Plan with respect to which awards may be granted is 3,200,000. No further grants will be allowed under the 2002 Incentive Plan. At December 31, 2022, there were 444,216 shares available for future grant. Grants outstanding under the plans as of December 31, 2022, were comprised of 138,482 restricted shares.

Grants made under the Incentive Plan during the years 2020 through 2022 were as follows.

Vesting of these shares is dependent upon the attainment of pre-established performance objectives, and any difference between shares granted and shares earned at the end of the performance period will be reported at the conclusion of the performance period.

(4) The shares represent a true-up of previously awarded performance-based restricted share awards. The updated shares were calculated based on the attainment of pre-established performance objectives.

Reinsurance

We reinsure with other insurance companies a portion of our potential liability under the policies we have underwritten, thereby protecting us against an unexpectedly large loss or a catastrophic occurrence that could produce large losses, primarily in our homeowners line of business. We use various software products to measure our exposure to catastrophe losses and the probable maximum loss to us for catastrophe losses such as hurricanes. The models include estimates for our share of the catastrophe losses generated in the residual market for property insurance by the FAIR Plan. The reinsurance market has seen from the various software modelers, increases in the estimate of damage from hurricanes in the southern and northeast portions of the United States due to revised estimations of increased hurricane activity and increases in the estimation of demand surge in the periods following a significant event. We continue to manage and model our exposure and adjust our reinsurance programs as a result of the changes to the models. As of January 1, 2022, we purchased three layers of excess catastrophe reinsurance providing $590,000 of coverage for property losses in excess of $75,000 up to a maximum of $665,000. Our reinsurers’ co-participation is 80.0% of $75,000 for the 1st layer, 80.0% of $250,000 for the 2nd layer, and 80.0% of $265,000 for the 3rd layer. As a result of the changes to the models, our catastrophe reinsurance in 2022 protects us in the event of a “135-year storm” (that is, a storm of a severity expected to occur once in a 135-year period). Most of our reinsurers have an A.M. Best rating of “A+” (Superior) or “A” (Excellent).

We are a participant in CAR, a state-established body that runs the residual market reinsurance programs for commercial automobile insurance in Massachusetts under which premiums, expenses, losses and loss adjustment expenses on ceded business are shared by all insurers writing commercial automobile insurance in Massachusetts. We also participate in the Massachusetts Property Insurance Underwriting Association (“FAIR Plan”), in which premiums, expenses, losses and loss adjustment expenses on homeowners business that cannot be placed in the voluntary market are shared by all insurers writing homeowners insurance in Massachusetts. The FAIR Plan buys reinsurance to reduce their exposure to catastrophe losses. On July 1, 2022, the FAIR Plan purchased $1,800,000 of catastrophe reinsurance for property losses with retention of $100,000.

We also had $115,058 due from CAR comprising of loss and loss adjustment expense reserves, unearned premiums and reinsurance recoverables.

Non-GAAP Measures

Management has included certain non-generally accepted accounting principles (“non-GAAP”) financial measures in presenting the Company’s results. Management believes that these non-GAAP measures better explain the Company’s results of operations and allow for a more complete understanding of the underlying trends in the Company’s business. These measures should not be viewed as a substitute for those determined in accordance with GAAP. In addition, our definitions of these items may not be comparable to the definitions used by other companies.

Non-GAAP operating income and non-GAAP operating income per diluted share consist of our GAAP net income adjusted by the net realized gains on investments, net impairment losses on investments, changes in net unrealized gains on equity securities, credit loss benefit (expense) and taxes related thereto. Net income and earnings per diluted share are the GAAP financial measures that are most directly comparable to non-GAAP operating income and non-GAAP operating income per diluted share, respectively. A reconciliation of the GAAP financial measures to these non-GAAP measures is included in the financial highlights below.

Earnings from Partnership Investments. Earnings from partnership investments were $12,484 for the year ended December 31, 2022 compared to $19,829 for the year ended December 31, 2021. The 2022 earnings reflect a decrease in investment appreciation and timing of cash proceeds received compared to the prior year. Timing and generation of these returns on capital can vary based on the results and transactions of the underlying partnerships.

Net Realized Gains on Investments.  Net realized gains on investments were $9,190 for the year ended December 31, 2022 compared to $14,885 for the comparable 2021 period.

The gross unrealized gains and losses on investments in fixed maturity securities, including redeemable preferred stocks that have characteristics of fixed maturities, equity securities, including interests in mutual funds, and other invested assets were as follows:

The Company’s analysis of its fixed maturity portfolio at December 31, 2022 concluded that $678 of unrealized losses were due to credit factors and were recorded as an allowance for expected credit losses at December 31, 2022, compared to $691 at December 31, 2021. The Company concluded that outside of the securities that were recognized as credit impaired, the unrealized losses recorded on the fixed maturity portfolio at December 31, 2022 and December 31, 2021 resulted from fluctuations in market interest rates and other temporary market conditions as opposed to fundamental changes in the credit quality of the issuers of such securities. Based upon the analysis performed, the Company’s decision to hold these securities, the Company’s current level of liquidity and our history of positive operating cash flows, management believes it is more likely than not that it will not be required to sell any of its securities before the anticipated recovery in the fair value to its amortized cost basis.

Specific qualitative analysis was also performed for securities appearing on our “Watch List,” if any.

Qualitative analysis considered such factors as the financial condition and the near term prospects of the issuer, whether the debtor is current on its contractually obligated interest and principal payments, changes to the rating of the security by a rating agency and the historical volatility of the fair value of the security.

The majority of unrealized losses recorded on the investment portfolio at December 31, 2022 resulted from fluctuations in market interest rates and other temporary market conditions as opposed to fundamental changes in the credit quality of the issuers of such securities. Given our current level of liquidity, the fact that we do not intend to sell these securities, and that it is more likely than not that we will not be required to sell these securities prior to recovery of the cost basis of these securities, these decreases in values are viewed as being temporary.

For information regarding fair value measurements of our investment portfolio, refer to Item 8—Financial Statements and Supplementary Data, Note 16, Fair Value of Financial Instruments, of this Form 10-K.

Commission Income: Commission income includes revenues from new and renewal commissions paid by insurance carriers, which we recognize when earned.

Finance and Other Service Income.  Finance and other service income includes revenues from premium installment charges, which we recognize when earned, and other miscellaneous income and fees. Finance and other service income decreased by $780, or 5.1%, to $14,461 for the year ended December 31, 2022 from $15,241 for the comparable 2021 period. The decrease is primarily driven by a change in our late fee assessment policy.

Losses and Loss Adjustment Expenses.  Losses and loss adjustment expenses incurred for the year ended December 31, 2022 increased by $30,252, or 6.6%, to $491,979 from $461,727 for the comparable 2021 period. The increase in losses is due to a return of pre-pandemic frequency in our private passenger automobile line of business and current market conditions including inflation and supply chain delays.

Our GAAP loss ratio for the years ended December 31, 2022 and 2021 were 64.9% and 59.6%, respectively. Our GAAP loss ratio excluding loss adjustment expenses was 56.0% and 50.0% for the years ended December 31, 2022 and 2021, respectively. Total prior year favorable development included in the pre-tax results for the year ended December 31, 2022 was $57,279, compared to $53,673, for the comparable 2021 period. The increase in the prior year favorable development in 2022 is primarily related to the reversal of $6,500 legal expense reserve during the second quarter of 2022.

Underwriting, Operating and Related Expenses.  Underwriting, operating and related expenses for the year ended December 31, 2022 decreased by $13,247, or 5.1%, to $245,145 from $258,392 for the comparable 2021 period. Our GAAP expense ratio for the year ended December 31, 2022 decreased to 32.3% from 33.4% for the comparable 2021 period. The 2022 decrease is driven by a decrease in contingent commission expense.

Other Expense: Other expense includes the operating and related expenses associated with SNIA.

Interest Expense.  Interest expense was $524 and $522 for the years ended December 31, 2022 and 2021, respectively. Interest expense primarily relates to the borrowing from the FHLB as noted within Item 8 – Financial Statements and Supplementary Data, Note 10, Debt, of this Form 10-K. The credit facility commitment fee included in interest expense was $75 for each of the years ended December 31, 2022 and 2021.

Income Tax Expense.  Our effective tax rates were 21.9% and 20.4% for the years ended December 31, 2022 and 2021, respectively. The effective rates for the year ended December 31, 2022 was higher than the statutory rate primary due to the impact of stock-based and executive compensation. The effective tax rates for the year end December 31, 2021 were lower than the statutory rates primarily due to the effects of tax-exempt investment income and the impact of stock-based compensation.

The comparison of results for the year ended December 31, 2021 compared to the year ended December 31, 2020 can be found in the Company’s 2021 Annual Report on Form 10-K filed with the SEC on February 28, 2022.

Liquidity and Capital Resources

As a holding company, Safety’s assets consist primarily of the stock of our direct and indirect subsidiaries. Our principal source of funds to meet our obligations and pay dividends to shareholders, therefore, is dividends and other permitted payments from our subsidiaries, principally Safety Insurance. Safety is the borrower under our credit facility.

Safety Insurance’s sources of funds primarily include premiums received, investment income and proceeds from sales and redemptions of investments. Safety Insurance’s principal uses of cash are the payment of claims, operating expenses and taxes, the purchase of investments and payment of dividends to Safety.

Net cash provided by operating activities was $44,326, $141,394, and $109,460 during the years ended December 31, 2022, 2021, and 2020, respectively.  Our operations typically generate positive cash flows from operations as most premiums are received in advance of the time when claim and benefit payments are required. These positive operating cash flows are expected to continue to meet our liquidity requirements.

Net cash used for investing activities was $19,988, $65,989, and $35,524 for the years ended December 31, 2022, 2021, and 2020, respectively, as purchases of fixed maturity and equity securities exceeded proceeds from the sales, paydowns, calls and maturities of fixed maturity and equity securities.

Net cash used for financing activities was $62,641, $65,571, and $64,574 during the years ended December 31, 2022, 2021 and 2020, respectively. Net cash used for financing activities during the year ended December 31, 2022 and December 31, 2021 is comprised of dividend payments to shareholders and share buybacks, partially offset by the proceeds from a $5,000 borrowing from the FHLB-Boston on December 29, 2022. The borrowing was for a term of one-month, bearing interest at a rate of 4.34%, and was repaid on January 27, 2023. Net cash used for financing activities during the year ended December 31, 2020 is comprised of dividend payments to shareholders and share buybacks, partially offset by the proceeds from a $30,000 borrowing from the FHLB-Boston on March 17, 2020. The borrowing is for a term of five years, bearing interest at a rate of 1.42%. Interest is payable monthly, and the principal is due on the maturity date of March 17, 2025 but may be prepaid in whole or in part by the Company in advance.

The Insurance Subsidiaries maintain a high degree of liquidity within their respective investment portfolios in fixed maturity and short-term investments. We do not anticipate the need to sell these securities to meet the Insurance Subsidiaries cash requirements. We expect the Insurance Subsidiaries to generate sufficient operating cash to meet all short-term and long-term cash requirements. However, there can be no assurance that unforeseen business needs or other items will not occur causing us to have to sell securities before their values fully recover; thereby causing us to recognize additional impairment charges in that time period.

Regulatory Matters

Our insurance company’s subsidiaries are subject to various regulatory restrictions that limit the maximum amount of dividends available to be paid to their parent without prior approval of the Commissioner. The Massachusetts statute limits the dividends an insurer may pay in any twelve-month period, without the prior permission of the

45

Table of Contents

Commissioner, to the greater of (i) 10% of the insurer’s surplus as of the preceding December 31 or (ii) the insurer’s net income for the twelve-month period ending the preceding December 31, in each case determined in accordance with statutory accounting practices. Our Insurance Subsidiaries may not declare an “extraordinary dividend” (defined as any dividend or distribution that, together with other distributions made within the preceding twelve months, exceeds the limits established by Massachusetts statute) until thirty days after the Commissioner has received notice of the intended dividend and has not objected. As historically administered by the Commissioner, this provision requires the Commissioner’s prior approval of an extraordinary dividend. Under Massachusetts law, an insurer may pay cash dividends only from its unassigned funds, also known as earned surplus, and the insurer’s remaining surplus must be both reasonable in relation to its outstanding liabilities and adequate to its financial needs. At year-end 2022, the statutory surplus of Safety Insurance was $782,200, and its net income for 2022 was $66,197. As a result, a maximum of $78,220 is available in 2022 for such dividends without prior approval of the Commissioner. As a result of this Massachusetts statute, the Insurance Subsidiaries had restricted net assets in the amount of $703,980 at December 31, 2022. During the twelve months ended December 31, 2022, Safety Insurance recorded dividends to Safety of $94,260.

The maximum dividend permitted by law is not indicative of an insurer’s actual ability to pay dividends, which may be constrained by business and regulatory considerations, such as the impact of dividends on surplus, which could affect an insurer’s ratings or competitive position, the amount of premiums that can be written and the ability to pay future dividends.

Since the initial public offering of its common stock in November 2002, the Company has paid regular quarterly dividends to shareholders of its common stock. Quarterly dividends paid during 2022 and 2021 were as follows:

November 2, 2022December 1, 2022December 15, 2022$0.90$13,207

On February 15, 2023, our Board approved and declared a quarterly cash dividend on our common stock of $0.90 per share to be paid on March 15, 2023 to shareholders of record on March 1, 2023. We plan to continue to declare and pay quarterly cash dividends in 2023, depending on our financial position and the regularity of our cash flows.

On February 23, 2022, the Board approved a share repurchase program of up to $50,000 of the Company’s outstanding common shares.  The Board of Directors had cumulatively authorized increases to the existing share repurchase program of up to $200,000 of its outstanding common shares.  Under the program, the Company may repurchase shares of its common stock for cash in public or private transactions, in the open market or otherwise.  The timing of such repurchases and actual number of shares repurchased will depend on a variety of factors including price, market conditions and applicable regulatory and corporate requirements.  The program does not require the Company to repurchase any specific number of shares and may be modified, suspended or terminated at any time without prior notice. As of December 31, 2022, the Company had purchased 3,141,477 shares on the open market at a cost $150,000. As of December 31, 2021, the Company had purchased 2,970,573 shares on the open market at a cost of $135,397. In connection with the acquisition of Northeast / Metrowest, the Company reissued 58,113 shares valued at $5,000.

The Company purchased an additional 170,904 shares on the open market at a cost of $14,603 through February 23, 2022. As of that date, the previously authorized share repurchase program in the amount of $150 million has been utilized.

Management believes that the current level of cash flow from operations provides us with sufficient liquidity to meet our operating needs over the next 12 months. We expect to be able to continue to meet our operating needs after

46

Table of Contents

the next 12 months from internally generated funds. Since our ability to meet our obligations in the long term (beyond such twelve-month period) is dependent upon such factors as market changes, insurance regulatory changes and economic conditions, no assurance can be given that the available net cash flow will be sufficient to meet our operating needs. We expect that we would need to borrow or issue capital stock if we needed additional funds, for example, to pay for an acquisition or a significant expansion of our operations. There can be no assurance that sufficient funds for any of the foregoing purposes would be available to us at such time.

Contractual Obligations

We have obligations to make future payments under contracts and credit-related financial instruments and commitments.

As of December 31, 2022, the Company had loss and LAE reserves of $549,598, unpaid reinsurance recoverables of $93,394 and net loss and LAE reserves of $456,204. Our loss and LAE reserves are estimates as described in more detail under Critical Accounting Policies and Estimates. The specific amounts and timing of obligations related to case reserves, IBNR reserves and related LAE reserves are not set contractually, and the amounts and timing of these obligations are unknown. While management believes that historical performance of loss payment patterns is a reasonable source for projecting future claims payments, there is inherent uncertainty in this estimated projected settlement of loss and LAE reserves, and as a result these estimates will differ, perhaps significantly, from actual future payments.

As part of the Company’s investment activity, we have committed $160,000 to investments in limited partnerships.  The Company has contributed $114,418 to these commitments as of December 31, 2022.  As of December 31, 2022, the remaining committed capital that could be called is $52,000, which includes potential recallable capital distributions.

Critical Accounting Policies and Estimates

Loss and Loss Adjustment Expense Reserves

Significant periods of time can elapse between the occurrence of an insured loss, the reporting to us of that loss and our final payment of that loss. To recognize liabilities for unpaid losses, we establish reserves as balance sheet liabilities. Our reserves represent estimates of amounts needed to pay reported and estimated losses incurred but not yet reported (“IBNR”) and the expenses of investigating and paying those losses, or loss adjustment expenses. Every quarter, we review our previously established reserves and adjust them, if necessary.

When a claim is reported, claims personnel establish a “case reserve” for the estimated amount of the ultimate payment. The amount of the reserve is primarily based upon an evaluation of the type of claim involved, the circumstances surrounding each claim and the policy provisions relating to the loss. The estimate reflects the informed judgment of such personnel based on general insurance reserving practices and on the experience and knowledge of the claims person. During the loss adjustment period, these estimates are revised as deemed necessary by our claims department based on subsequent developments and periodic reviews of the cases. When a claim is closed with or without a payment, the difference between the case reserve and the settlement amount creates a reserve deficiency if the payment exceeds the case reserve or a reserve redundancy if the payment is less than the case reserve.

In accordance with industry practice, we also maintain reserves for IBNR. IBNR reserves are determined in accordance with commonly accepted actuarial reserving techniques on the basis of our historical information and experience. We review and make adjustments to incurred but not yet reported reserves quarterly. In addition, IBNR reserves can also be expressed as the total loss reserves required less the case reserves on reported claims.

47

Table of Contents

When reviewing reserves, we analyze historical data and estimate the impact of various loss development factors, such as our historical loss experience and that of the industry, trends in claims frequency and severity, our mix of business, our claims processing procedures, legislative enactments, judicial decisions, legal developments in imposition of damages, and changes and trends in general economic conditions, including the effects of inflation. A change in any of these factors from the assumption implicit in our estimate can cause our actual loss experience to be better or worse than our reserves, and the difference can be material. There is no precise method, however, for evaluating the impact of any specific factor on the adequacy of reserves, because the eventual development of reserves is affected by many factors.

In estimating all our loss reserves, we follow the guidance prescribed by ASC 944, Financial Services – Insurance.

Management determines our loss and loss adjustment expense reserves estimate based upon the analysis of our actuaries. A reasonable estimate is derived by selecting a point estimate within a range of indications as calculated by our actuaries using generally accepted actuarial techniques. The key assumption in most actuarial analysis is that past patterns of frequency and severity will repeat in the future, unless a significant change in the factors described above takes place. Our key factors and resulting assumptions are the ultimate frequency and severity of claims, based upon the most recent ten years of claims reported to the Company, and the data CAR reports to us to calculate our share of the residual market, as of the date of the applicable balance sheet. For each accident year and each coverage within a line of business our actuaries calculate the ultimate losses incurred. Our total reserves are the difference between the ultimate losses incurred and the cumulative loss and loss adjustment payments made to date. Our IBNR reserves are calculated as the difference between our total reserves and the outstanding case reserves at the end of the accounting period. To determine ultimate losses, our actuaries calculate a range of indications and select a point estimation using such actuarial techniques as:

Column 1Column 2Column 3
Paid Loss Indications: This method projects ultimate loss estimates based upon extrapolations of historic paid loss trends. This method tends to be used on short tail lines such as automobile physical damage.
Column 1Column 2Column 3
Incurred Loss Indications: This method projects ultimate loss estimates based upon extrapolations of historic incurred loss trends. This method tends to be used on long tail lines of business such as automobile liability and homeowner’s liability.
Column 1Column 2Column 3
Bornhuetter-Ferguson Indications: This method projects ultimate loss estimates based upon extrapolations of an expected amount of IBNR, which is added to current incurred losses or paid losses. This method tends to be used on small, immature, or volatile lines of business, such as our BOP and umbrella lines of business.
Column 1Column 2Column 3
Bodily Injury Code Indications: This method projects ultimate loss estimates for our private passenger and commercial automobile bodily injury coverage based upon extrapolations of the historic number of accidents and the historic number of bodily injury claims per accident. Projected ultimate bodily injury claims are then segregated into expected claims by type of injury (e.g. soft tissue injury vs. hard tissue injury) based on past experience. An ultimate severity, or average paid loss amounts, is estimated based upon extrapolating historic trends. Projected ultimate loss estimates using this method are the aggregate of estimated losses by injury type.

Such techniques assume that past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate basis for predicting our ultimate losses, total reserves and resulting IBNR reserves. It is possible that the final outcome may fall above or below these amounts as a result of a number of factors, including immature data, sparse data, or significant growth in a line of business. Using these methodologies our actuaries established a range of reasonably possible estimations for net reserves of approximately $423,452 to $481,902 as of December 31, 2022 compared to a range of $445,511 to $504,580 as of December 31, 2021. In general, the low and high values of the ranges represent reasonable minimum and maximum values of the indications based on the techniques described above. Our selected point estimate of net loss and loss adjustment expense reserves based upon the analysis of our actuaries was $456,204 as of December 31, 2022 compared to $479,984 as of December 31, 2021.

At December 31, 2022 and 2021, our total IBNR reserves for our private passenger automobile line of business were comprised of $(67,848) and $(60,228) related to estimated ultimate decreases in the case reserves, including anticipated recoveries (i.e. salvage and subrogation), and $24,320 and $17,352 related to our estimation for not yet reported losses, respectively.

Our IBNR reserves consist of our estimate of the total loss reserves required less our case reserves.  The IBNR reserves for CAR assumed commercial automobile business are 40.3% of our total reserves for CAR assumed commercial automobile business as of December 31, 2022 due to the reporting delays in the information we receive from CAR, as described further in the section on Residual Market Loss and Loss Adjustment Expense Reserves.  Our IBNR reserves for FAIR Plan assumed homeowners are 58.9% of our total reserves for FAIR Plan assumed homeowners at December 31, 2022 due to similar reporting delays in the information we receive from FAIR Plan.

Residual Market Loss and Loss Adjustment Expense Reserves

We are a participant in CAR, the FAIR Plan and other various residual markets and assume a portion of losses and LAE on business ceded by the industry participants to the residual markets.  We estimate reserves for assumed losses and LAE that have not yet been reported to us by the residual markets.  Our estimations are based upon the same factors we use for our own reserves, plus additional factors due to the nature of and the information we receive.

Residual market deficits consist of premium ceded to the various residual markets less losses and LAE and is allocated among insurance companies based on a various formulas (the “Participation Ratio”) that take into consideration a company’s voluntary market share.

Because of the lag in the various residual market estimations, and in order to try to validate to the extent possible the information provided, we estimate the effects of the actions of our competitors in order to establish our Participation Ratio.

Although we rely to a significant extent in setting our reserves on the information the various residual markets provide, we are cautious in our use of that information, because of the delays in receiving data from the various residual markets.  As a result, we have to estimate our Participation Ratio and these reserves are subject to significant judgments and estimates.

Sensitivity Analysis

Establishment of appropriate reserves is an inherently uncertain process. There can be no certainty that currently established reserves based on our key assumptions regarding frequency and severity in our lines of business, or our assumptions regarding our share of the CAR loss will prove adequate in light of subsequent actual experience. To the extent that reserves are inadequate and are strengthened, the amount of such increase is treated as a charge to earnings in the period that the deficiency is recognized. To the extent that reserves are redundant and are released, the amount of the release is a credit to earnings in the period the redundancy is recognized.  For the twelve months ended December 31, 2022, a 1 percentage-point change in the loss and LAE ratio would result in a change in reserves of $7,588. Each 1 percentage-point change in the loss and loss expense ratio would have had a $5,995 effect on net income, or $0.41 per diluted share.

Our assumptions consider that past experience, adjusted for the effects of current developments and anticipated trends, are an appropriate basis for establishing our reserves. Our individual key assumptions could each have a reasonable possible range of plus or minus 5 percentage-points for each estimation, although there is no guarantee that our assumptions will not have more than a 5 percentage point variation.  The following sensitivity tables present information for each of our primary lines of business on the effect each 1 percentage-point change in each of our key assumptions on unpaid frequency and severity could have on our retained (i.e., direct minus ceded) loss and LAE reserves and net income for the twelve months ended December 31, 2022. In evaluating the information in the table, it should be noted that a 1 percentage-point change in a single assumption would change estimated reserves by 1 percentage-point.  A 1 percentage-point change in both our key assumptions would change estimated reserves within a range of plus or minus 2 percentage-points.

Our estimated share of CAR loss and LAE reserves is based on assumptions about our Participation Ratio, the size of CAR, and the resulting deficit (similar assumptions apply with respect to the FAIR Plan).  Our assumptions consider that past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate basis for establishing our CAR reserves. Each of our assumptions could have a reasonably possible range of plus or minus 5 percentage-points for each estimation.

The following sensitivity table presents information of the effect each 1 percentage-point change in our assumptions on our share of reserves for CAR and other residual markets could have on our assumed loss and LAE reserves and net income for the year ended December 31, 2022. In evaluating the information in the table, it should be noted that a 1 percentage-point change in our assumptions would change estimated reserves by 1 percentage-point.

Reserve Development Summary

The changes we have recorded in our reserves in the past illustrate the uncertainty of estimating reserves. Our prior year reserves decreased by $57,279, $53,673 and $54,844 during the years ended December 31, 2022, 2021, and 2020, respectively.

The following table presents a comparison of prior year development of our net reserves for losses and LAE for the years ended December 31, 2022, 2021 and 2020, respectively. Each accident year represents all claims for an annual accounting period in which loss events occurred, regardless of when the losses are actually reported, booked or paid.  Our financial statements reflect the aggregate results of the current and all prior accident years.

All prior years$(57,279)$(53,673)$(54,844)

At the end of each period, the reserves were re-estimated for all prior accident years. Our prior year reserves decreased by $57,279, $53,673, and $54,844 for the years ended 2022, 2021, and 2020, respectively. The decreases in prior year reserves in 2022 resulted from re-estimations of prior year’s ultimate loss and LAE liabilities and are primarily composed of reductions of $20,241 in our retained automobile reserves and $32,963 in our retained other than auto and homeowner’s reserves. The decreases in prior year reserves in 2021 resulted from re-estimations of prior year’s ultimate loss and LAE liabilities and are primarily composed of reductions of $22,313 in our retained automobile reserves and $26,220 in our retained other than auto and homeowner reserves. The decrease in prior year reserves during 2020 are primarily composed of reductions of $26,902 in our retained automobile reserves and $21,717 in our retained homeowners reserves. It is not appropriate to extrapolate future favorable or unfavorable development of reserves from this past experience.

The improved retained private passenger and commercial automobile results were primarily due to fewer IBNR claims than previously estimated and better than previously estimated severity on our established bodily injury and property damage case reserves.  Our retained other than auto and homeowners line of business prior year reserves decreased, due primarily to fewer IBNR claims than previously estimated.

In estimating all our loss reserves, we follow the guidance prescribed by ASC 944, Financial Services-Insurance.

Investment Impairments

The Company uses a systematic methodology to evaluate declines in fair values below cost or amortized cost of our investments. Some of the factors considered in assessing impairment of fixed maturities due to credit losses include the extent to which the fair value is less than amortized cost, the financial condition of and the near and long-term prospects of the issuer, whether the debtor is current on its contractually obligated interest and principal payments, changes to the rating of the security by a rating agency, the historical volatility of the fair value of the security and whether it is more like than not that the Company will be required to sell the investment prior to an anticipated recovery in value. This methodology ensures that we evaluate available evidence concerning any declines in a disciplined manner.

For fixed maturities that the Company does not intend to sell or for which it is more likely than not that the Company would not be required to sell before an anticipated recovery in value, the Company separates the expected credit loss component of the impairment from the amount related to all other factors. The expected credit loss component is recognized as an allowance for expected credit losses. The allowance is adjusted for any additional credit losses and subsequent recoveries, which are booked in income as either credit loss expense or credit loss benefit, respectively. Upon recognizing a credit loss, the cost basis is not adjusted. The impairment related to all other factors (non-credit factors) is reported in other comprehensive income.

For further information, see “Results of Operations: Credit Loss Benefit (Expense).”

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with our accompanying consolidated financial statements and notes thereto, which appear elsewhere in this document. In this discussion, all dollar amounts are presented in thousands, except share and per share data.

The following discussion contains forward-looking statements. We intend statements which are not historical in nature to be, and are hereby identified as “forward-looking statements” to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. In addition, the Company’s senior management may make forward-looking statements orally to analysts, investors, the media and others. This safe harbor requires that we specify important factors that could cause actual results to differ materially from those contained in forward-looking statements made by or on behalf of us. We cannot promise that our expectations in such forward-looking statements will turn out to be correct. Our actual results could be materially different from and worse than our expectations. See “Forward-Looking Statements” below for specific important factors that could cause actual results to differ materially from those contained in forward-looking statements.

Executive Summary and Overview

In this discussion, “Safety” refers to Safety Insurance Group, Inc. and “our Company,” “we,” “us” and “our” refer to Safety Insurance Group, Inc. and its consolidated subsidiaries. Our subsidiaries consist of Safety Insurance Company (“Safety Insurance”), Safety Indemnity Insurance Company (“Safety Indemnity”), Safety Property and Casualty Insurance Company (“Safety P&C”), Safety Northeast Insurance Company (“Safety Northeast”), Safety Asset Management Corporation (“SAMC”), and Safety Management Corporation, which is SAMC’s holding company.

We are a leading provider of private passenger automobile (53.6% of our direct written premiums in 2021), commercial automobile, (16.2% of 2021 direct written premiums), and homeowners (24.9% of 2021 direct written premiums) insurance. In addition to these coverages, we offer a portfolio of other insurance products, including dwelling fire, umbrella and business owner policies (totaling 5.3% of 2021 direct written premiums).  Operating exclusively in Massachusetts, New Hampshire and Maine through our insurance company subsidiaries, Safety Insurance, Safety Indemnity, Safety P&C, and Safety Northeast (together referred to as the “Insurance Subsidiaries”), we have established strong relationships with independent insurance agents, who numbered 856 in 1,088 locations throughout these three states during 2021. We have used these relationships and our extensive knowledge of the market to become the fourth largest private passenger automobile carrier and the second largest commercial automobile carrier in Massachusetts, capturing an approximate 7.9% and 12.0% share, respectively, of the Massachusetts private passenger and commercial automobile markets in 2021, according to statistics compiled by CAR based on automobile exposures. We are the third largest homeowners insurance carrier in Massachusetts, with a market share of 6.8% in 2020. Our principal competitors within the Massachusetts homeowners insurance market are MAPFRE SA, Liberty Mutual Insurance and The Andover Companies, which held 12.5%, 9.1% and 6.2% market shares respectively in 2020 (according to S&P Global Market Intelligence).

Our Insurance Subsidiaries began writing insurance in New Hampshire during 2008 and Maine in 2016. In November 2020, we formed a fourth insurance subsidiary, Safety Northeast, which became licensed to write insurance products in Massachusetts in January of 2021. The table below shows the amount of direct written premiums in each state during the years ended December 31, 2021, 2020, and 2019.

Recent Trends and Events

Beginning in March 2020, the global pandemic associated with the novel coronavirus COVID-19 (“COVID-19”) and related economic conditions caused significant economic effects including temporary closures of many businesses and reduced consumer activity due to shelter-in-place, stay-at-home and other governmental actions. The Company has continued to take many actions that address the health and well-being of our employees while still serving the needs of our agents and insureds.

There are many uncertainties with respect to COVID-19. For further discussion regarding the potential impacts of COVID-19 and related economic conditions on the Company, see "Part I—Item 1A—Risk Factors." These risks include legal challenges or legislative actions that extend business interruption coverage outside of our policy terms for business owner policies, which require direct physical loss or damage to property. As discussed in Note 8 – Commitments and Contingencies, the Company has been named in a lawsuit alleging that the Company improperly denied coverage to commercial insureds for loss of business income resulting from the COVID-19 pandemic. Our business owner policies serve eligible small and medium sized commercial accounts including but not limited to apartments and condominiums; mercantile establishments; limited cooking restaurants; offices; and special trade contractors. The majority of these business owner policies do not contain a specific exclusion for viruses. However, as viruses do not produce direct physical damage or loss to property, our position is that no coverage exists for this peril. As result, the Company accrued a reserve of $6,500 for legal defense costs in 2020. This amount is still accrued as of December 31, 2021. While we continue to evaluate each claim based on the specific facts and circumstances involved, our business owner policies do not provide coverage for business interruption claims unless there is direct physical damage or loss to property.

Losses and Loss Adjustment Expenses.  Losses and loss adjustment expenses incurred for the year ended December 31, 2021 increased by $57,171, or 14.1%, to $461,727 from $404,556 for the comparable 2020 period. The 2020 losses and loss adjustment expenses reflected a decrease in frequency, primarily in our private passenger automobile line of business as a result of the COVID-19 pandemic.

Loss, expense, and combined ratios calculated under U.S. generally accepted accounting principles for the quarter ended December 31, 2021 were 62.7%, 33.7%, and 96.4%, respectively, compared to 48.8%, 36.3%, and 85.1%, respectively, for the comparable 2020 period. Loss, expense, and combined ratios calculated under U.S. generally accepted accounting principles for the year ended December 31, 2021 were 59.6%, 33.4%, and 93.0%, respectively, compared to 52.5%, 34.6%, and 87.1%, respectively, for the comparable 2020 period. The 2021 decrease in the expense ratios in both periods is driven by a decrease in contingent commission expense.

We define a “catastrophe” as an event that produces pre-tax losses before reinsurance in excess of $1,000 and involves multiple first-party policyholders, or an event that produces a number of claims in excess of a preset, per-event threshold of average claims in a specific area, occurring within a certain amount of time following the event. Catastrophes are caused by various natural events including high winds, winter storms, tornadoes, hailstorms, and hurricanes. The nature and level of catastrophes in any period cannot be reliably predicted.

Catastrophe losses incurred by the type of event are shown in the following table.

Statutory Accounting Principles

Our results are reported in accordance with GAAP, which differ from amounts reported in accordance with statutory accounting principles ("SAP") as prescribed by insurance regulatory authorities, which in general reflect a liquidating, rather than going concern concept of accounting. Specifically, under GAAP:

Column 1Column 2Column 3
Policy acquisition costs such as commissions, premium taxes and other variable costs incurred which are directly related to the successful acquisition of a new or renewal insurance contract are capitalized and amortized on a pro rata basis over the period in which the related premiums are earned, rather than expensed as incurred, as required by SAP.

Column 1Column 2Column 3
Certain assets are included in the consolidated balance sheets whereas, under SAP, such assets are designated as "nonadmitted assets," and charged directly against statutory surplus. These assets consist primarily of premium receivables that are outstanding over ninety days, federal deferred tax assets in excess of statutory limitations, furniture, equipment, leasehold improvements and prepaid expenses.

Column 1Column 2Column 3
Amounts related to ceded reinsurance are shown gross of ceded unearned premiums and reinsurance recoverables, rather than netted against unearned premium reserves and loss and loss adjustment expense reserves, respectively, as required by SAP.

Column 1Column 2Column 3
Fixed maturities securities, which are classified as available-for-sale, are reported at current fair values, rather than at amortized cost, or the lower of amortized cost or market, depending on the specific type of security, as required by SAP.

Column 1Column 2Column 3
The differing treatment of income and expense items results in a corresponding difference in federal income tax expense. Changes in deferred income taxes are reflected as an item of income tax benefit or expense, rather than recorded directly to surplus as regards policyholders, as required by SAP. Admittance testing may result in a charge to unassigned surplus for non-admitted portions of deferred tax assets. Under GAAP reporting, a valuation allowance may be recorded against the deferred tax asset and reflected as an expense.

Insurance Ratios

The property and casualty insurance industry uses the combined ratio as a measure of underwriting profitability.  The combined ratio is the sum of the loss ratio (losses and loss adjustment expenses incurred as a percent of net earned premiums) plus the expense ratio (underwriting and other expenses as a percent of net earned premiums, calculated on a GAAP basis).  The combined ratio reflects only underwriting results and does not include income from

investments or finance and other service income.  Underwriting profitability is subject to significant fluctuations due to competition, catastrophic events, weather, economic and social conditions, and other factors.

Our GAAP insurance ratios are presented in the following table for the periods indicated.

Share-Based Compensation

On April 2, 2018, the Company’s Board of Directors adopted the Safety Insurance Group, Inc. 2018 Long-Term Incentive Plan (“the 2018 Plan”), which was subsequently approved by our shareholders at the 2018 Annual Meeting of Shareholders. The 2018 Plan enables the grant of stock awards, performance shares, cash-based performance units, other stock-based awards, stock options, stock appreciation rights, and stock unit awards, each of which may be granted separately or in tandem with other awards. Eligibility to participate includes officers, directors, employees and other individuals who provide bona fide services to the Company. The 2018 Plan supersedes the Company’s 2002 Management Omnibus Incentive Plan (“the 2002 Incentive Plan”).

The 2018 Plan establishes an initial pool of 350,000 shares of common stock available for issuance to our employees and other eligible participants.

The maximum number of shares of common stock between both the 2018 Plan and 2002 Incentive Plan with respect to which awards may be granted is 2,850,000. No further grants will be allowed under the 2002 Incentive Plan. At December 31, 2021, there were 164,908 shares available for future grant. Grants outstanding under the Plans as of December 31, 2021, were comprised of 137,589 restricted shares.

Grants made under the Incentive Plan during the years 2019 through 2021 were as follows.

Reinsurance

We reinsure with other insurance companies a portion of our potential liability under the policies we have underwritten, thereby protecting us against an unexpectedly large loss or a catastrophic occurrence that could produce large losses, primarily in our homeowners line of business. We use various software products to measure our exposure to catastrophe losses and the probable maximum loss to us for catastrophe losses such as hurricanes. The models include estimates for our share of the catastrophe losses generated in the residual market for property insurance by the FAIR Plan. The reinsurance market has seen from the various software modelers, increases in the estimate of damage from hurricanes in the southern and northeast portions of the United States due to revised estimations of increased hurricane activity and increases in the estimation of demand surge in the periods following a significant event. We continue to manage and model our exposure and adjust our reinsurance programs as a result of the changes to the models. As of January 1, 2021, we have purchased four layers of excess catastrophe reinsurance providing $615,000 of coverage for property losses in excess of $50,000 up to a maximum of $665,000. Our reinsurers’ co-participation is 50.0% of $50,000 for the 1st layer, 80.0% of $50,000 for the 2nd layer, 80.0% of $250,000 for the 3rd layer and 80.0% of $265,000 for the 4th layer. As a result of the changes to the models, our catastrophe reinsurance in 2021 protects us in the event of a “135-year storm” (that is, a storm of a severity expected to occur once in a 135-year period). Most of our reinsurers have an A.M. Best rating of “A+” (Superior) or “A” (Excellent).

We are a participant in CAR, a state-established body that runs the residual market reinsurance programs for commercial automobile insurance in Massachusetts under which premiums, expenses, losses and loss adjustment expenses on ceded business are shared by all insurers writing commercial automobile insurance in Massachusetts. We also participate in the FAIR Plan in which premiums, expenses, losses and loss adjustment expenses on homeowners business that cannot be placed in the voluntary market are shared by all insurers writing homeowners insurance in Massachusetts. The FAIR Plan buys reinsurance to reduce their exposure to catastrophe losses. On July 1, 2021, the FAIR Plan purchased $1,800,000 of catastrophe reinsurance for property losses with retention of $100,000.

We also had $119,122 due from CAR comprising of loss and loss adjustment expense reserves, unearned premiums and reinsurance recoverables.

Effects of Inflation

We do not believe that inflation has had a material effect on our consolidated results of operations, except insofar as inflation may affect interest rates.

Non-GAAP Measures

Management has included certain non-generally accepted accounting principles (“non-GAAP”) financial measures in presenting the Company’s results. Management believes that these non-GAAP measures better explain the Company’s results of operations and allow for a more complete understanding of the underlying trends in the Company’s business. These measures should not be viewed as a substitute for those determined in accordance with generally accepted accounting principles (“GAAP”). In addition, our definitions of these items may not be comparable to the definitions used by other companies.

Non-GAAP operating income and non-GAAP operating income per diluted share consist of our GAAP net income adjusted by the net realized gains on investments, net impairment losses on investments, changes in net unrealized gains on equity securities, credit loss benefit (expense) and taxes related thereto. Net income and earnings per diluted share are the GAAP financial measures that are most directly comparable to non-GAAP operating income and non-GAAP operating income per diluted share, respectively. A reconciliation of the GAAP financial measures to these non-GAAP measures is included in the financial highlights below.

YEAR ENDED DECEMBER 31, 2021 COMPARED TO YEAR ENDED DECEMBER 31, 2020

Direct Written Premiums.  Direct written premiums for the year ended December 31, 2021 increased by $3,427, or 0.4%, to $802,139 from $798,712 for the comparable 2020 period. The 2020 period reflects the Safety Personal Auto Relief Credit, a 15% policyholder credit, representing $17,711 in total premium which was applied to personal auto policies for the months of April, May and June 2020 as well as changes made by CAR to eligibility requirements which impacted the number of commercial automobile policies that we handle as a Servicing Carrier to the ceded pool. This results in a commensurate decrease in ceded written premium to and assumed from these programs.

Net Written Premiums.  Net written premiums for the year ended December 31, 2021 increased by $989, or 0.1%, to $764,526 from $763,537 for the comparable 2020 period. The 2021 increase was primarily due to the factors

that increased direct written premiums.

Net Earned Premiums.  Net earned premiums for the year ended December 31, 2021 increased by $3,250, or 0.4%, to $774,328 from $771,078 for the comparable 2020 period. The 2021 increase was primarily due to the factors that increased direct written premiums.

The effect of reinsurance on net written and net earned premiums is presented in the following table.

Net Investment Income.  Net investment income for the year ended December 31, 2021 increased by $3,090, or 7.5%, to $44,135 from $41,045 for the comparable 2020 period. The increase is a result of an increase in the average invested asset balance and an increase in the equity in earnings of other invested assets compared to the prior year. Net effective annual yield on the investment portfolio was 3.0% for the year ended December 31, 2021 compared to 2.9% for the year ended December 31, 2020. Our duration was 3.6 years at December 31, 2021, compared to 3.2 years at December 31, 2020.

Earnings from Partnership Investments. Earnings from partnership investments were $19,829 for the year ended December 31, 2021 compared to $6,901 for the year ended December 31, 2020. The 2021 earnings reflects an increase in investment appreciation and distribution of investment returns compared to the prior year. Timing and generation of these returns on capital can vary based on the results and transactions of the underlying partnerships.

Net Realized Gains on Investments.  Net realized gains on investments were $14,885 for the year ended December 31, 2021 compared to $957 for the comparable 2020 period. The increase is a result of an increase in realized gains on the sale of equity securities compared to the prior year.

The Company’s analysis of its fixed maturity portfolio at December 31, 2021 concluded that $691 of unrealized losses were due to credit factors and were recorded as an allowance for expected credit losses at December 31, 2021, compared to $1,054 at December 31, 2020. The Company concluded that outside of the securities that were recognized as credit impaired, the unrealized losses recorded on the fixed maturity portfolio at December 31, 2021 and December 31, 2020 resulted from fluctuations in market interest rates and other temporary market conditions as opposed to fundamental changes in the credit quality of the issuers of such securities. Based upon the analysis performed, the Company’s decision to hold these securities, the Company’s current level of liquidity and our history of positive operating cash flows, management believes it is more likely than not that it will not be required to sell any of its securities before the anticipated recovery in the fair value to its amortized cost basis.

Specific qualitative analysis was also performed for securities appearing on our “Watch List,” if any.

Qualitative analysis considered such factors as the financial condition and the near term prospects of the issuer, whether the debtor is current on its contractually obligated interest and principal payments, changes to the rating of the security by a rating agency and the historical volatility of the fair value of the security.

The majority of unrealized losses recorded on the investment portfolio at December 31, 2021 resulted from fluctuations in market interest rates and other temporary market conditions as opposed to fundamental changes in the credit quality of the issuers of such securities. Given our current level of liquidity, the fact that we do not intend to sell these securities, and that it is more likely than not that we will not be required to sell these securities prior to recovery of the cost basis of these securities, these decreases in values are viewed as being temporary.

For information regarding fair value measurements of our investment portfolio, refer to Item 8—Financial Statements and Supplementary Data, Note 16, Fair Value of Financial Instruments, of this Form 10-K.

Finance and Other Service Income.  Finance and other service income includes revenues from premium installment charges, which we recognize when earned, and other miscellaneous income and fees. Finance and other service income decreased by $1,631, or 9.7%, to $15,241 for the year ended December 31, 2021 from $16,872 for the comparable 2020 period. The decrease is primarily driven by a change in our late fee assessment policy. The 2020 period also reflects a moratorium on certain policy cancellations and fees that were in place during 2020 as a result of the COVID-19 pandemic.

Losses and Loss Adjustment Expenses.  Losses and loss adjustment expenses incurred for the year ended December 31, 2021 increased by $57,171, or 14.1%, to $461,727 from $404,556 for the comparable 2020 period. The 2020 losses and loss adjustment expenses reflected a decrease in frequency, primarily in our private passenger automobile line of business as a result of the COVID-19 pandemic.

Our GAAP loss ratio for the years ended December 31, 2021 and 2020 were 59.6% and 52.5%, respectively. Our GAAP loss ratio excluding loss adjustment expenses was 50.0% and 43.7% for the years ended December 31, 2021 and 2020, respectively. Total prior year favorable development included in the pre-tax results for the year ended December 31, 2021 was $53,673, compared to $54,844, for the comparable 2020 period.

Underwriting, Operating and Related Expenses.  Underwriting, operating and related expenses for the year ended December 31, 2021 decreased by $8,090, or 3.0%, to $258,392 from $266,482 for the comparable 2020 period.

Table of Contents

Our GAAP expense ratio for the year ended December 31, 2021 decreased to 33.4% from 34.6% for the comparable 2020 period. The 2021 decrease is driven by a decrease in contingent commission expense.

Interest Expense.  Interest expense was $522 and $440 for the years ended December 31, 2021 and 2020, respectively. Interest expense primarily relates to the borrowing from the FHLB as noted within Item 8 – Financial Statements and Supplementary Data, Note 10, Debt, of this Form 10-K. The credit facility commitment fee included in interest expense was $75 for each of the years ended December 31, 2021 and 2020.

Income Tax Expense   Our effective tax rates were 20.4% and 20.9% for the years ended December 31, 2021 and 2020, respectively. The effective rates for the years ended December 31, 2021 and 2020 were lower than the statutory rates primarily due to the effects of tax-exempt investment income and the impact of stock-based compensation.

The comparison of results for the year ended December 31, 2020 compared to the year ended December 31, 2019 can be found in the Company’s 2020 Annual Report on Form 10-K filed with the SEC on February 26, 2021.

Liquidity and Capital Resources

As a holding company, Safety’s assets consist primarily of the stock of our direct and indirect subsidiaries. Our principal source of funds to meet our obligations and pay dividends to shareholders, therefore, is dividends and other permitted payments from our subsidiaries, principally Safety Insurance. Safety is the borrower under our credit facility.

Safety Insurance’s sources of funds primarily include premiums received, investment income and proceeds from sales and redemptions of investments. Safety Insurance’s principal uses of cash are the payment of claims, operating expenses and taxes, the purchase of investments and payment of dividends to Safety.

Net cash provided by operating activities was $141,394, $109,460, and $112,456 during the years ended December 31, 2021, 2020, and 2019, respectively.  Our operations typically generate positive cash flows from operations as most premiums are received in advance of the time when claim and benefit payments are required. These positive operating cash flows are expected to continue to meet our liquidity requirements.

Net cash used for investing activities was $65,989, $35,524, and $52,964 for the years ended December 31, 2021, 2020, and 2019, respectively, as purchases of fixed maturity and equity securities exceeded proceeds from the sales, paydowns, calls and maturities of fixed maturity and equity securities.

Net cash used for financing activities was $65,571, $64,574, and $52,667 during the years ended December 31, 2021, 2020 and 2019, respectively. Net cash used for financing activities during the year ended December 31, 2021 is comprised of dividend payments to shareholders and share buybacks. Net cash used for financing activities during the year ended December 31, 2020 is comprised of dividend payments to shareholders and share buybacks, partially offset by the proceeds from a $30,000 borrowing from the FHLB-Boston on March 17, 2020. The borrowing is for a term of five years, bearing interest at a rate of 1.42%. Interest is payable monthly, and the principal is due on the maturity date of March 17, 2025 but may be prepaid in whole or in part by the Company in advance. Net cash used for financing activities during the years ended December 31, 2019 is comprised of dividend payments to shareholders.

The Insurance Subsidiaries maintain a high degree of liquidity within their respective investment portfolios in fixed maturity and short-term investments. We do not anticipate the need to sell these securities to meet the Insurance Subsidiaries cash requirements. We expect the Insurance Subsidiaries to generate sufficient operating cash to meet all short-term and long-term cash requirements. However, there can be no assurance that unforeseen business needs or other items will not occur causing us to have to sell securities before their values fully recover; thereby causing us to recognize additional impairment charges in that time period.

Regulatory Matters

Our insurance company’s subsidiaries are subject to various regulatory restrictions that limit the maximum amount of dividends available to be paid to their parent without prior approval of the Commissioner. The Massachusetts statute limits the dividends an insurer may pay in any twelve-month period, without the prior permission of the Commissioner, to the greater of (i) 10% of the insurer’s surplus as of the preceding December 31 or (ii) the insurer’s net income for the twelve-month period ending the preceding December 31, in each case determined in accordance with statutory accounting practices. Our Insurance Subsidiaries may not declare an “extraordinary dividend” (defined as any dividend or distribution that, together with other distributions made within the preceding twelve months, exceeds the limits established by Massachusetts statute) until thirty days after the Commissioner has received notice of the intended dividend and has not objected. As historically administered by the Commissioner, this provision requires the Commissioner’s prior approval of an extraordinary dividend. Under Massachusetts law, an insurer may pay cash dividends only from its unassigned funds, also known as earned surplus, and the insurer’s remaining surplus must be both reasonable in relation to its outstanding liabilities and adequate to its financial needs. At year-end 2021, the statutory surplus of Safety Insurance was $826,979, and its net income for 2021 was $97,169. As a result, a maximum of $97,169 is available in 2021 for such dividends without prior approval of the Commissioner. As a result of this Massachusetts statute, the Insurance Subsidiaries had restricted net assets in the amount of $729,810 at December 31, 2021. During the twelve months ended December 31, 2021, Safety Insurance recorded dividends to Safety of $49,488.

The maximum dividend permitted by law is not indicative of an insurer’s actual ability to pay dividends, which may be constrained by business and regulatory considerations, such as the impact of dividends on surplus, which could affect an insurer’s ratings or competitive position, the amount of premiums that can be written and the ability to pay future dividends.

Since the initial public offering of its common stock in November 2002, the Company has paid regular quarterly dividends to shareholders of its common stock. Quarterly dividends paid during 2021 and 2020 were as follows:

On February 15, 2022, our Board approved and declared a quarterly cash dividend on our common stock of $0.90 per share to be paid on March 15, 2022 to shareholders of record on March 1, 2022. We plan to continue to declare and pay quarterly cash dividends in 2022, depending on our financial position and the regularity of our cash flows.

On August 3, 2007, the Board of Directors approved a share repurchase program of up to $30,000 of the Company’s outstanding common shares.  The Board of Directors had cumulatively authorized increases to the existing share repurchase program of up to $150,000 of its outstanding common shares.  Under the program, the Company may repurchase shares of its common stock for cash in public or private transactions, in the open market or otherwise.  The timing of such repurchases and actual number of shares repurchased will depend on a variety of factors including price, market conditions and applicable regulatory and corporate requirements.  The program does not require the Company to repurchase any specific number of shares and may be modified, suspended or terminated at any time without prior notice. As of December 31, 2021, the Company had purchased 2,970,573 shares on the open market at a cost $135,397. As of December 31, 2020, the Company had purchased 2,831,168 shares on the open market at a cost of $123,834. The Company purchased an additional 170,904 shares on the open market at a cost of $14,603 through February 23, 2022. As of that date, the previously authorized share repurchase program in the amount of $150 million has been utilized. On February 23, 2022, the Board approved an increase to the Company’s share repurchase program of up to $50,000 of the Company’s outstanding common shares. Under the program, the Company may repurchase shares of its common stock for cash in public or private transactions, in the open market or otherwise, at management’s discretion. The timing of such repurchases and actual number of shares repurchased will depend on a variety of factors including price, market conditions and applicable regulatory and corporate requirements. The program does not require the Company to repurchase any specific number of shares and may be modified, suspended or terminated at any time without prior notice.

Management believes that the current level of cash flow from operations provides us with sufficient liquidity to meet our operating needs over the next 12 months. We expect to be able to continue to meet our operating needs after the next 12 months from internally generated funds. Since our ability to meet our obligations in the long term (beyond such twelve-month period) is dependent upon such factors as market changes, insurance regulatory changes and economic conditions, no assurance can be given that the available net cash flow will be sufficient to meet our operating needs. We expect that we would need to borrow or issue capital stock if we needed additional funds, for example, to pay for an acquisition or a significant expansion of our operations. There can be no assurance that sufficient funds for any of the foregoing purposes would be available to us at such time.

Contractual Obligations

We have obligations to make future payments under contracts and credit-related financial instruments and commitments.

As of December 31, 2021, the Company had loss and LAE reserves of $570,651, unpaid reinsurance recoverables of $90,667 and net loss and LAE reserves of $479,984. Our loss and LAE reserves are estimates as described in more detail under Critical Accounting Policies and Estimates. The specific amounts and timing of obligations related to case reserves, IBNR reserves and related LAE reserves are not set contractually, and the amounts and timing of these obligations are unknown. While management believes that historical performance of loss payment patterns is a reasonable source for projecting future claims payments, there is inherent uncertainty in this estimated projected settlement of loss and LAE reserves, and as a result these estimates will differ, perhaps significantly, from actual future payments. Our operations typically generate substantial positive cash flows from operations as most premiums are received in advance of the time when claim and benefit payments are required. These positive operating cash flows are expected to continue to meet our liquidity requirements, including any unexpected variations in the timing of claim settlements.

As part of the Company’s investment activity, we have committed $145,000 to investments in limited partnerships.  The Company has contributed $94,269 to these commitments as of December 31, 2021.  As of December 31, 2021, the remaining committed capital that could be called is $54,516, which includes potential recallable capital distributions.

Critical Accounting Policies and Estimates

Loss and Loss Adjustment Expense Reserves

Significant periods of time can elapse between the occurrence of an insured loss, the reporting to us of that loss and our final payment of that loss. To recognize liabilities for unpaid losses, we establish reserves as balance sheet liabilities. Our reserves represent estimates of amounts needed to pay reported and unreported losses and the expenses of investigating and paying those losses, or loss adjustment expenses. Every quarter, we review our previously established reserves and adjust them, if necessary.

When a claim is reported, claims personnel establish a “case reserve” for the estimated amount of the ultimate payment. The amount of the reserve is primarily based upon an evaluation of the type of claim involved, the circumstances surrounding each claim and the policy provisions relating to the loss. The estimate reflects the informed judgment of such personnel based on general insurance reserving practices and on the experience and knowledge of the claims person. During the loss adjustment period, these estimates are revised as deemed necessary by our claims department based on subsequent developments and periodic reviews of the cases. When a claim is closed with or without a payment, the difference between the case reserve and the settlement amount creates a reserve deficiency if the payment exceeds the case reserve or a reserve redundancy if the payment is less than the case reserve.

In accordance with industry practice, we also maintain reserves for IBNR. IBNR reserves are determined in accordance with commonly accepted actuarial reserving techniques on the basis of our historical information and experience. We review and make adjustments to incurred but not yet reported reserves quarterly. In addition, IBNR reserves can also be expressed as the total loss reserves required less the case reserves on reported claims.

When reviewing reserves, we analyze historical data and estimate the impact of various loss development factors, such as our historical loss experience and that of the industry, trends in claims frequency and severity, our mix of business, our claims processing procedures, legislative enactments, judicial decisions, legal developments in imposition of damages, and changes and trends in general economic conditions, including the effects of inflation. A change in any of these factors from the assumption implicit in our estimate can cause our actual loss experience to be better or worse than our reserves, and the difference can be material. There is no precise method, however, for evaluating the impact of any specific factor on the adequacy of reserves, because the eventual development of reserves is affected by many factors.

In estimating all our loss reserves, we follow the guidance prescribed by ASC 944, Financial Services – Insurance.

Management determines our loss and LAE reserves estimate based upon the analysis of our actuaries. A reasonable estimate is derived by selecting a point estimate within a range of indications as calculated by our actuaries using generally accepted actuarial techniques. The key assumption in most actuarial analysis is that past patterns of frequency and severity will repeat in the future, unless a significant change in the factors described above takes place. Our key factors and resulting assumptions are the ultimate frequency and severity of claims, based upon the most recent ten years of claims reported to the Company, and the data CAR reports to us to calculate our share of the residual market, as of the date of the applicable balance sheet. For each accident year and each coverage within a line of business our actuaries calculate the ultimate losses incurred. Our total reserves are the difference between the ultimate losses incurred and the cumulative loss and loss adjustment payments made to date. Our IBNR reserves are calculated as the difference between our total reserves and the outstanding case reserves at the end of the accounting period. To determine ultimate losses, our actuaries calculate a range of indications and select a point estimation using such actuarial techniques as:

Column 1Column 2Column 3
Paid Loss Indications: This method projects ultimate loss estimates based upon extrapolations of historic paid loss trends. This method tends to be used on short tail lines such as automobile physical damage.
Column 1Column 2Column 3
Incurred Loss Indications: This method projects ultimate loss estimates based upon extrapolations of historic incurred loss trends. This method tends to be used on long tail lines of business such as automobile liability and homeowner’s liability.

Table of Contents

Column 1Column 2Column 3
Bornhuetter-Ferguson Indications: This method projects ultimate loss estimates based upon extrapolations of an expected amount of IBNR, which is added to current incurred losses or paid losses. This method tends to be used on small, immature, or volatile lines of business, such as our BOP and umbrella lines of business.
Column 1Column 2Column 3
Bodily Injury Code Indications: This method projects ultimate loss estimates for our private passenger and commercial automobile bodily injury coverage based upon extrapolations of the historic number of accidents and the historic number of bodily injury claims per accident. Projected ultimate bodily injury claims are then segregated into expected claims by type of injury (e.g. soft tissue injury vs. hard tissue injury) based on past experience. An ultimate severity, or average paid loss amounts, is estimated based upon extrapolating historic trends. Projected ultimate loss estimates using this method are the aggregate of estimated losses by injury type.

Such techniques assume that past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate basis for predicting our ultimate losses, total reserves and resulting IBNR reserves. It is possible that the final outcome may fall above or below these amounts as a result of a number of factors, including immature data, sparse data, or significant growth in a line of business. Using these methodologies our actuaries established a range of reasonably possible estimations for net reserves of approximately $445,511 to $504,580 as of December 31, 2021 compared to a range of $424,437 to $478,251 as of December 31, 2020. In general, the low and high values of the ranges represent reasonable minimum and maximum values of the indications based on the techniques described above. Our selected point estimate of net loss and LAE reserves based upon the analysis of our actuaries was $479,984 as of December 31, 2021 compared to $461,270 as of December 31, 2020.

The following tables present the point estimation of the recorded reserves and the range of estimations by line of business for net loss and LAE reserves as of December 31, 2021 and December 31, 2020.

At December 31, 2021 and 2020, our total IBNR reserves for our private passenger automobile line of business were comprised of $(60,228) and $(45,308) related to estimated ultimate decreases in the case reserves, including anticipated recoveries (i.e. salvage and subrogation), and $17,352 and $15,901 related to our estimation for not yet reported losses, respectively.

Our IBNR reserves consist of our estimate of the total loss reserves required less our case reserves.  The IBNR reserves for CAR assumed commercial automobile business are 42.8% of our total reserves for CAR assumed commercial automobile business as of December 31, 2021 due to the reporting delays in the information we receive from CAR, as described further in the section on Residual Market Loss and Loss Adjustment Expense Reserves.  Our IBNR reserves for FAIR Plan assumed homeowners are 66.0% of our total reserves for FAIR Plan assumed homeowners at December 31, 2021 due to similar reporting delays in the information we receive from FAIR Plan.

Residual Market Loss and Loss Adjustment Expense Reserves

We are a participant in CAR, the FAIR Plan and other various residual markets and assume a portion of losses and LAE on business ceded by the industry participants to the residual markets.  We estimate reserves for assumed losses and LAE that have not yet been reported to us by the residual markets.  Our estimations are based upon the same factors we use for our own reserves, plus additional factors due to the nature of and the information we receive.

Residual market deficits consist of premium ceded to the various residual markets less losses and LAE and is allocated among insurance companies based on a various formulas (the “Participation Ratio”) that take into consideration a company’s voluntary market share.

Because of the lag in the various residual market estimations, and in order to try to validate to the extent possible the information provided, we estimate the effects of the actions of our competitors in order to establish our Participation Ratio.

Although we rely to a significant extent in setting our reserves on the information the various residual markets provide, we are cautious in our use of that information, because of the delays in receiving data from the various residual markets.  As a result, we have to estimate our Participation Ratio and these reserves are subject to significant judgments and estimates.

Sensitivity Analysis

Establishment of appropriate reserves is an inherently uncertain process. There can be no certainty that currently established reserves based on our key assumptions regarding frequency and severity in our lines of business, or our assumptions regarding our share of the CAR loss will prove adequate in light of subsequent actual experience. To the extent that reserves are inadequate and are strengthened, the amount of such increase is treated as a charge to earnings in the period that the deficiency is recognized. To the extent that reserves are redundant and are released, the amount of the release is a credit to earnings in the period the redundancy is recognized.  For the twelve months ended December 31, 2021, a 1 percentage-point change in the loss and LAE ratio would result in a change in reserves of $7,743. Each 1 percentage-point change in the loss and loss expense ratio would have had a $6,117 effect on net income, or $0.41 per diluted share.

Our assumptions consider that past experience, adjusted for the effects of current developments and anticipated trends, are an appropriate basis for establishing our reserves. Our individual key assumptions could each have a reasonable possible range of plus or minus 5 percentage-points for each estimation, although there is no guarantee that our assumptions will not have more than a 5 percentage point variation.  The following sensitivity tables present information for each of our primary lines of business on the effect each 1 percentage-point change in each of our key assumptions on unpaid frequency and severity could have on our retained (i.e., direct minus ceded) loss and LAE reserves and net income for the twelve months ended December 31, 2021. In evaluating the information in the table, it should be noted that a 1 percentage-point change in a single assumption would change estimated reserves by 1 percentage-point.  A 1 percentage-point change in both our key assumptions would change estimated reserves within a range of plus or minus 2 percentage-points.

Our estimated share of CAR loss and LAE reserves is based on assumptions about our Participation Ratio, the size of CAR, and the resulting deficit (similar assumptions apply with respect to the FAIR Plan).  Our assumptions consider that past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate basis for establishing our CAR reserves. Each of our assumptions could have a reasonably possible range of plus or minus 5 percentage-points for each estimation.

The following sensitivity table presents information of the effect each 1 percentage-point change in our assumptions on our share of reserves for CAR and other residual markets could have on our assumed loss and LAE reserves and net income for the year ended December 31, 2021. In evaluating the information in the table, it should be noted that a 1 percentage-point change in our assumptions would change estimated reserves by 1 percentage-point.

Reserve Development Summary

The changes we have recorded in our reserves in the past illustrate the uncertainty of estimating reserves. Our prior year reserves decreased by $53,673, $54,844 and $42,049 during the years ended December 31, 2021, 2020, and 2019, respectively.

The following table presents a comparison of prior year development of our net reserves for losses and LAE for the years ended December 31, 2021, 2020 and 2019, respectively. Each accident year represents all claims for an annual accounting period in which loss events occurred, regardless of when the losses are actually reported, booked or paid.  Our financial statements reflect the aggregate results of the current and all prior accident years.

At the end of each period, the reserves were re-estimated for all prior accident years. Our prior year reserves decreased by $53,673, $54,844, and $42,049 for the years ended 2021, 2020, and 2019, respectively. The decreases in prior year reserves in 2021 resulted from re-estimations of prior year’s ultimate loss and LAE liabilities and are primarily composed of reductions of $22,313 in our retained automobile reserves and $26,220 in our retained other than auto and homeowner’s reserves. The decreases in prior year reserves in 2020 resulted from re-estimations of prior year’s ultimate loss and LAE liabilities and are primarily composed of reductions of $26,902 in our retained automobile reserves and $21,717 in our retained other than auto and homeowner reserves. The decrease in prior year reserves during 2019 resulted from re-estimations of prior year's ultimate loss and LAE liabilities and are primarily composed of reductions of $25,623 in our retained automobile reserves and $14,182 in our retained homeowners reserves. It is not appropriate to extrapolate future favorable or unfavorable development of reserves from this past experience.

In estimating all our loss reserves, including CAR, we follow the guidance prescribed by ASC 944, Financial Services-Insurance.

For further information, see “Results of Operations: Losses and Loss Adjustment Expenses.”

Investment Impairments

The Company uses a systematic methodology to evaluate declines in fair values below cost or amortized cost of our investments. Some of the factors considered in assessing impairment of fixed maturities due to credit losses include the extent to which the fair value is less than amortized cost, the financial condition of and the near and long-term prospects of the issuer, whether the debtor is current on its contractually obligated interest and principal payments, changes to the rating of the security by a rating agency, the historical volatility of the fair value of the security and whether it is more like than not that the Company will be required to sell the investment prior to an anticipated recovery in value. This methodology ensures that we evaluate available evidence concerning any declines in a disciplined manner.

For fixed maturities that the Company does not intend to sell or for which it is more likely than not that the Company would not be required to sell before an anticipated recovery in value, the Company separates the expected credit loss component of the impairment from the amount related to all other factors. The expected credit loss component is recognized as an allowance for expected credit losses. The allowance is adjusted for any additional credit losses and subsequent recoveries, which are booked in income as either credit loss expense or credit loss benefit, respectively. Upon recognizing a credit loss, the cost basis is not adjusted. The impairment related to all other factors (non-credit factors) is reported in other comprehensive income.

For further information, see “Results of Operations: Credit Loss Benefit (Expense).”
