The Company cautions readers not to place undue reliance on any forward-looking statements, which speak only as of the date on which they are made, and advises readers that various factors,
including, but not limited to, those described above and other factors discussed in the Company’s annual and quarterly reports previously filed with the SEC, could affect the Company’s financial performance and could cause the Company’s actual
results or circumstances for future periods to differ materially from those anticipated or projected.

Unless required by law, the Company does not undertake, and specifically disclaims any obligations to, publicly release any revisions that may be made to any forward-looking statements to
reflect the occurrence of anticipated or unanticipated events or circumstances after the date of such statements.

Non-GAAP Measures

This Quarterly Report on Form 10-Q contains financial information determined by methods other than in accordance with GAAP. Where non-GAAP disclosures are used in this Form 10-Q, the comparable GAAP
measure, as well as a reconciliation to the comparable GAAP measure, is provided in the accompanying tables. Management believes that these non-GAAP measures provide useful information that is important to an understanding of the results of the
Company’s core business as well as provide information standard in the financial institution industry. Non-GAAP measures should not be considered a substitute for financial measures determined in accordance with GAAP and investors should consider
the Company’s performance and financial condition as reported under GAAP and all other relevant information when assessing the performance or financial condition of the Company. Amounts previously reported in the consolidated financial statements
are reclassified whenever necessary to conform to current period presentation.

Critical Accounting Estimates

SEC guidance requires disclosure of “critical accounting estimates.” The SEC defines “critical accounting estimates” as those estimates made in accordance with GAAP that involve a significant level
of estimation uncertainty and have had or are reasonably likely to have a material impact on the financial condition or results of operations of the registrant. The Company follows financial accounting and reporting policies that are in
accordance with GAAP. The more significant of these policies are summarized in Note 1 to the consolidated financial statements presented in our 2025 Annual Report on Form 10-K. Management has reviewed the application of these estimates with the
Audit Committee of NBT’s Board of Directors. The allowance for credit losses and unfunded commitments policies are deemed to meet the SEC’s definition of a critical accounting estimate.

Allowance for Credit Losses and Unfunded Commitments

The allowance for credit losses consists of the allowance for credit losses and the allowance for losses on unfunded commitments. The measurement of CECL on financial instruments requires an
estimate of the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses under the CECL methodology is based on relevant information about past events, current conditions, and reasonable
and supportable forecasts that affect the collectability of the reported amounts. Historical loss experience is generally the starting point for estimating expected credit losses. The Company then considers whether the historical loss experience
should be adjusted for asset-specific risk characteristics or current conditions at the reporting date that did not exist over the period from which historical experience was used. Finally, the Company considers forecasts about future economic
conditions that are reasonable and supportable. The allowance for credit losses for loans, as reported in our consolidated statements of financial condition, is adjusted by an expense for credit losses, which is recognized in earnings, and
reduced by the charge-off of loan amounts, net of recoveries. The allowance for losses on unfunded commitments represents the expected credit losses on off-balance sheet commitments such as unfunded commitments to extend credit and standby
letters of credit. However, a liability is not recognized for commitments unconditionally cancellable by the Company. The allowance for losses on unfunded commitments is determined by estimating future draws and applying the expected loss rates
on those draws.

Table of Contents

Management of the Company considers the accounting policy relating to the allowance for credit losses to be a critical accounting estimate given the uncertainty in evaluating the level of the
allowance required to cover management’s estimate of all expected credit losses over the expected contractual life of our loan portfolio. Determining the appropriateness of the allowance is complex and requires judgment by management about the
effect of matters that are inherently uncertain. Subsequent evaluations of the then-existing loan portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for credit losses in those future periods.
While management’s current evaluation of the allowance for credit losses indicates that the allowance is appropriate, the allowance may need to be increased under adversely different conditions or assumptions. The impact of utilizing the CECL
methodology to calculate the reserve for credit losses will be significantly influenced by the composition, characteristics and quality of our loan portfolio, as well as the prevailing economic conditions and forecasts utilized. Material changes
to these and other relevant factors may result in greater volatility to the reserve for credit losses, and therefore, greater volatility to our reported earnings.

One of the most significant judgments involved in estimating the Company’s allowance for credit losses relates to the macroeconomic forecasts used to estimate expected credit losses over the
forecast period. As of March 31, 2026, the weightings were 60%, 5%, and 35% for the baseline, upside and downside economic forecast scenarios, respectively. The baseline outlook reflected an economic environment where the northeast unemployment
rate decreases from 4.6% in the second quarter of 2026 to 4.56% by the end of the forecast period, with a peak northeast unemployment rate of 4.6% in the third quarter of 2026. National GDP annualized growth (on a quarterly basis) is expected to
start the second quarter of 2026 at approximately 2.75% and decrease to 1.72% by the end of the forecast period. Key assumptions in the baseline economic outlook included the Federal Reserve cutting rates with two 25 basis point cuts at the June
and September meetings and the economy remaining at full employment. The alternative upside scenario assumes improved economic conditions from the baseline outlook. Under this scenario, northeast unemployment falls from 4.6% in the first quarter
of 2026 to 3.

General

NBT Bancorp Inc. is a registered financial holding company headquartered in Norwich, NY, with total assets of $16.00 billion at December 31, 2025. The Company’s business, primarily conducted through
the Bank and its full-service retirement plan administration and recordkeeping subsidiary and full-service regional insurance agency subsidiary, consists of providing commercial banking, retail banking and wealth management services primarily to
customers in its market area, which includes upstate New York, northeastern Pennsylvania, southern New Hampshire, western Massachusetts, Vermont, southern Maine and central and northwestern Connecticut. The Company has been, and intends to
continue to be, a community-oriented financial institution offering a variety of financial services. The Company’s business philosophy is to operate as a community bank with local decision-making, providing a broad array of banking and financial
services to retail, commercial and municipal customers. The financial review that follows focuses on the factors affecting the consolidated financial condition and results of operations of the Company and its wholly-owned subsidiaries, the Bank,
NBT Financial and NBT Holdings during 2025 and, in summary form, the preceding two years. NIM is presented in this discussion on an FTE basis. Average balances discussed are daily averages unless otherwise described. The audited consolidated
financial statements and related notes as of December 31, 2025 and 2024 and for each of the years in the three-year period ended December 31, 2025 should be read in conjunction with this review.

Critical Accounting Policies

The SEC defines critical accounting policies as accounting policies that are most important to a company’s financial results and condition. These policies are often subjective and require management to make
estimates about uncertain matters. The accounting and reporting policies followed by the Company conform, in all material respects, to accounting principles in accordance with GAAP and to general practices within the financial services industry.
In the course of normal business activity, management must select and apply many accounting policies and methodologies and make estimates and assumptions that lead to the financial results presented in the Company’s consolidated financial
statements and accompanying notes. There are uncertainties inherent in making these estimates and assumptions, which could materially affect the Company’s results of operations and financial position.

Table of Contents

Management considers accounting estimates to be critical to reported financial results if (i) the accounting estimates require management to make assumptions about matters that are highly uncertain,
and (ii) different estimates that management reasonably could have used for the accounting estimate in the current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, could have a material
impact on the Company’s financial statements. Management considers the accounting policies relating to the allowance for credit losses (“allowance”, or “ACL”) and the determination of fair values for acquired assets and assumed liabilities in a
business combination, including intangible assets such as goodwill, to be critical accounting policies because of the uncertainty and subjectivity involved in these policies and the material effect that estimates related to these areas can have
on the Company’s results of operations.

The Company’s methodology for estimating the allowance considers available relevant information about the collectability of cash flows, including information about past events, current conditions,
and reasonable and supportable forecasts. Refer to Note 1 and Note 6 to the consolidated financial statements included elsewhere in this report.

Goodwill represents the cost of the acquired business in excess of the fair value of the related net assets acquired. Following a merger, the determination of fair values for acquired assets and
assumed liabilities, including intangible assets such as goodwill, becomes critical. All acquired assets, including goodwill and other intangible assets, and assumed liabilities in purchase acquisitions are recorded at fair value as of the
acquisition date. The Company expenses all acquisition-related costs as incurred as required by ASC Topic 805, “Business Combinations.”

The determination of fair values for acquired loans in a business combination is a significant aspect of our financial reporting process. The valuation of acquired loans relied on a discounted cash
flow approach applied on a pooled basis, utilizing a forecast of principal and interest payments. This methodology segmented the acquired loan portfolio by loan type, term, interest rate, payment frequency and payment, and incorporated specific
key valuation assumptions, encompassing prepayment speeds, PD, LGD, and the discount rate to ascertain the fair value of these assets. Given the inherent subjectivity and reliance on future cash flows and market conditions, this process involves
considerable judgment and estimation uncertainty.

The Company conducts an annual review of goodwill impairment and conducts quarterly analyses to identify any events that may necessitate an interim assessment. The Company initially undertakes a
qualitative evaluation of goodwill to ascertain whether certain events or circumstances indicate a likelihood that the fair value of a reporting unit is less than its carrying amount. This qualitative evaluation demands considerable managerial
discretion, and if it suggests that the fair value of a reporting unit is unlikely to be less than the carrying value, no quantitative analysis is required. Inputs for this qualitative analysis requiring managerial judgment encompass
macroeconomic conditions, industry and market conditions, the financial performance of the reporting unit, and other pertinent events influencing the fair value of the reporting unit.

For information on the Company’s significant accounting policies and to gain a greater understanding of how the Company’s financial performance is reported, refer to Note 1 to the consolidated
financial statements included elsewhere in this report.

to these and other relevant factors may result in greater volatility to the reserve for credit losses, and therefore, greater volatility to our reported earnings.

One of the most significant judgments involved in estimating the Company’s allowance for credit losses relates to the macroeconomic forecasts used to estimate expected credit losses over the
forecast period. As of December 31, 2025, the quantitative model incorporated a baseline economic outlook along with an alternative upside scenario and two equally weighted downside scenarios, recessionary conditions and stagflation, sourced from
a reputable third-party to accommodate other potential economic conditions in the model. At December 31, 2025, the weightings were 65%, 5% and 30% for the baseline, upside and downside economic forecast scenarios, respectively. The baseline
outlook reflected an economic environment where the northeast unemployment rate increases from 4.5% in the first quarter of 2026 to 4.8% by the end of the forecast period, with a peak northeast unemployment rate of 4.9% in the fourth quarter of
2026. National GDP annualized growth (on a quarterly basis) is expected to start the first quarter of 2026 at approximately 2.55% and decrease to 1.8% by the end of the forecast period. Key assumptions in the baseline economic outlook included
the Federal Reserve cutting rates with one 25 basis point cut at the December meeting and the economy remaining at full employment. The alternative upside scenario assumes improved economic conditions from the baseline outlook. Under this
scenario, northeast unemployment falls from 4.4% in the fourth quarter of 2025 to 4.0% in the second quarter of 2026 and eventually settles at 4.1% by the end of the forecast period. The alternative downside scenario with recessionary conditions
assumes deteriorated economic conditions from the baseline outlook. Under this scenario, northeast unemployment rises from 4.4% in the fourth quarter of 2025 to a peak of 7.8% in the first quarter of 2027. The alternative downside stagflation
scenario assumes deteriorated economic conditions from the baseline outlook. Under this scenario, northeast unemployment rises from 4.4% in the fourth quarter of 2025 to 6% by the end of the forecast period in the second quarter of 2027, with a
peak northeast unemployment rate of 8.2% in the first quarter of 2028. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of December 31, 2025. Additional qualitative
adjustments were made for factors not incorporated in the forecasts or the model, such as loss rate expectations for certain loan pools, reversion adjustments for the stagflation scenario and recent trends in asset value indices. Additional
monitoring for industry concentrations, loan growth and policy exceptions was also conducted.

To demonstrate the sensitivity of the allowance for credit losses estimate to macroeconomic forecast weightings assumptions as of December 31, 2025, the Company changed the scenario weightings, with
a 10% increase to the downside scenarios, equally weighted, and a 10% decrease to the baseline scenario causing a 4% increase in the overall estimated allowance for credit losses. If instead the upside scenario was increased 10% and the baseline
scenario was decreased 10%, the overall estimated allowance for credit losses decreased 1%. To further demonstrate the sensitivity of the allowance for credit losses estimate to macroeconomic forecast weightings assumptions as of December 31,
2025, the Company increased the downside scenarios, equally weighted, to 100% which resulted in a 24% increase in the overall estimated allowance for credit losses.

2026 Outlook

The Company’s 2025 earnings reflected its continued ability to invest in the future while managing continued volatility in the current interest rate environment and overall economic conditions,
which have presented challenges across the financial services industry. 2025 was marked by resilient economic growth and while improving modestly, persistent inflation.

In 2025, the FOMC continued the easing cycle, which commenced in 2024, cutting the federal funds rate three times (September, October and December) by 25 bps each. Bringing the target range down
from 4.25%-4.50% towards a more neutral stance of 3.50%-3.75% as inflation pressures eased but growth softened. Actions included rate cuts, open market operations to manage liquidity and adjustments to reinvestment policies for Treasury and
mortgage-backed securities. The FOMC remained committed to its 2% inflation target and maximum employment goals, adjusting policy as economic data evolved. The cuts responded to a softening labor market and slowing economic growth, with rising
tariffs posing inflationary risks that the FOMC aimed to manage.

Deposit costs declined in 2025, but inversion in the midpoint of the yield curve continues to challenge interest rates for 2- to 5-year Treasuries and bank net interest margins. The good news is
the long end of the Treasury maturities is currently higher than short-term rates. It is hoped that further monetary policy easing will cut short-term interest rates further. This is an encouraging sign that the interest rate environment may be
finally returning to a “normal,” positively sloped yield curve.

The rate environment in 2026 is expected to improve but remain challenging. The monetary policy pivot has begun and should continue throughout the year. Interest rates continue to normalize, and
the return to a positively sloped yield curve is an encouraging sign. Deposit competition will remain fierce. The risk of recession is low. Overall, the rate environment is improving and is expected to benefit the banking industry. Future
decreases in rates by the Fed will be determined by labor market conditions and the levels of inflation.

The economic outlook for 2026 is generally positive with GDP growth in 2026 expected to be in the 2%-2.5% range driven by AI investment, strong consumer spending and potential tailwinds from
loosened monetary policy. Continued heavy investment in AI and related infrastructure is expected to be a primary driver of business investment and overall growth. Despite previous headwinds, consumer spending remains strong, supported by a
healthy labor market.

The Company continues to focus on long-term strategies including growth in its markets, diversification of revenue sources, improving operating efficiencies and investing in technology.

The Company’s 2026 outlook is subject to factors in addition to those identified above and those risks and uncertainties that could impact the Company’s future results are explained in Item 1A.
Risk Factors.

Asset/Liability Management

The Company attempts to maximize net interest income and net income, while actively managing its liquidity and interest rate sensitivity through the mix of various core deposit products and other
sources of funds, which in turn fund an appropriate mix of earning assets. The changes in the Company’s asset mix and sources of funds, and the resulting impact on net interest income, on an FTE basis, are discussed below. The following table
includes the condensed consolidated average balance sheet, an analysis of interest income/expense and average yield/rate for each major category of earning assets and interest-bearing liabilities on a taxable equivalent basis.

2025 OPERATING RESULTS AS COMPARED TO 2024 OPERATING RESULTS

Net Interest Income

Net interest income for the year ended December 31, 2025 was $501.5 million, up $101.4 million, or 25.3%, from 2024. The FTE NIM was 3.59% for the year ended December 31,
2025, an increase of 36 bps from 2024. Interest income increased $99.3 million, or 16.2%, as the yield on average interest-earning assets increased 16 bps from 2024 to 5.09%. Average interest-earning assets of $14.03 billion increased $1.58
billion primarily due to the addition of $1.95 billion in interest-earning assets in May 2025 from the Evans acquisition and organic earning asset growth. Interest expense decreased $2.1 million, or 1.0%, for the year ended December 31, 2025 as
compared to the year ended December 31, 2024 driven by interest-bearing deposit costs decreasing 27 bps, lower average balances of short-term borrowings and lower average balances of subordinated debt. The decrease in interest expense was
partially offset by the addition of $1.62 billion in interest-bearing liabilities in May 2025 from the Evans acquisition and organic growth. Included in net interest income was $21.0 million and $10.4 million for the years ended December 31,
2025 and 2024, respectively, of acquisition-related net accretion.

Loans and Corresponding Interest and Fees on Loans

The average balance of loans increased by approximately $1.24 billion, or 12.6%, from 2024 to 2025 driven by the Evans acquisition. Excluding the loans acquired from Evans, the increases in
C&I and indirect auto were offset by a reduction in the average balance of residential solar and other consumer loans. The yield on average loans increased from 5.64% in 2024 to 5.73% in 2025, as loans re-priced upward due to the interest
rate environment in 2025. FTE interest income from loans increased 14.3%, from $553.8 million in 2024 to $633.2 million in 2025. This increase was due to the improvement in asset yields and an increase in the average balance of earning assets.

Loans are summarized by business line which do not align to how the Company assesses credit risk in the allowance for credit losses under CECL.

Total loans were $11.60 billion and $9.97 billion at December 31, 2025 and 2024, respectively. Period end loans increased by $1.63 billion from December 31, 2024 to December 31, 2025, which included
$1.67 billion of loans acquired from Evans. Excluding the other consumer and residential solar portfolios, which are in a planned run-off status and the loans acquired from Evans, period end loans increased $68.1 million, or 0.7%, from December
31, 2024. From December 31, 2024 to December 31, 2025 C&I loans increased $245.5 million to $1.67 billion; CRE loans increased $922.3 million to $4.80 billion; and total consumer loans increased $460.5 million to $5.13 billion. Total loans
represent approximately 72.5% of assets as of December 31, 2025, as compared to 72.3% as of December 31, 2024.

Table of Contents

Loans in the C&I and CRE portfolios consist primarily of loans extended to small and medium-sized entities. The Company offers a variety of loan products tailored to meet the needs of commercial
customers including term loans, time notes and lines of credit. Such loans are made available to businesses for working capital needs such as inventory and receivables, business expansion, equipment purchases, livestock purchases and seasonal
crop expenses. These loans are typically collateralized by business assets such as equipment, accounts receivable and perishable agricultural products, which are inherently subject to industry price volatility. The Company extends CRE loans to
support real estate transactions, including acquisitions, refinancings, expansions and property improvements to both commercial and agricultural properties. These loans are secured by liens on real estate assets, covering a spectrum of properties
including apartments, commercial structures, healthcare facilities and others, whether occupied by owners or non-owners. Risks associated with the CRE portfolio pertain to the borrowers’ ability to meet interest and principal payments over the
life of the loan, as well as their ability to secure financing upon the loan’s maturity. The Company has a risk management framework that includes rigorous underwriting standards, targeted portfolio stress testing, interest rate sensitivities on
commercial borrowers and comprehensive credit risk monitoring mechanisms. The Company remains vigilant in monitoring market trends, economic indicators and regulatory developments to promptly adapt our risk management strategies as needed.

Within the CRE portfolio, approximately 78% are comprised of Non-Owner Occupied CRE, with the remaining 22% being Owner-Occupied CRE. Non-Owner Occupied CRE includes diverse sectors across the
Company’s markets such as residential rental properties (45%) and office spaces (13%), along with retail, manufacturing, mixed use, hotels and others. As of December 31, 2025 and December 31, 2024, the total CRE construction and development
loans amounted to $405.3 million and $314.8 million, respectively.

Residential mortgage loans consist primarily of loans secured by a first or second mortgage on primary residences. The Company originates both adjustable-rate and fixed-rate, one-to-four-family
residential loans for the construction or purchase of a residential property or refinancing of a mortgage. These loans are collateralized by properties located in the Company’s market area. The Company has never actively participated in
subprime mortgage lending, which has historically been one of the riskiest sectors in the residential housing market. Given the absence of a universally accepted definition of what constitutes “subprime” lending, the Company follows guidance
from the Office of Thrift Supervision and other federal bank regulators (the “Agencies”), as outlined in the “Expanded Guidance for Subprime Lending Programs,” or the Expanded Guidance, issued by the Agencies by press release dated January 31,
2001. As of December 31, 2025, there were $34.1 million in residential construction and development loans included in total loans.

The Company participated in the Small Business Administration’s (“SBA”) Paycheck Protection Program (“PPP”), a guaranteed, forgivable loan program created under the Coronavirus Aid, Relief and
Economic Security Act (“CARES Act”) and the Consolidated Appropriation Act targeted to provide small businesses with support to cover payroll and certain other expenses. Loans made under the PPP are fully guaranteed by the SBA, the guarantee is
backed by the full faith and credit of the United States government. PPP covered loans also afford borrowers forgiveness up to the principal amount of the PPP covered loan, plus accrued interest, if the loan proceeds are used to retain workers
and maintain payroll or to make certain mortgage interest, lease and utility payments, and certain other criteria are satisfied. The SBA will reimburse PPP lenders for any amount of a PPP covered loan that is forgiven, and PPP lenders will not
be held liable for any representations made by PPP borrowers in connection with their requests for loan forgiveness. Lenders receive pre-determined fees for processing and servicing PPP loans. In addition, PPP loans are risk-weighted at zero
percent under the generally applicable Standardized Approach used to calculate risk-weighted assets for regulatory capital purposes.

In 2017, the Company partnered with Sungage Financial, LLC. to offer financing to consumers for solar ownership with the program tailored for delivery through solar installers. Advances of credit
through this business line are to prime borrowers and are subject to the Company’s underwriting standards. Typically, the Company collects fees at origination that are deferred and recognized into interest income over the estimated life of the
loan. Residential solar loans are in a planned-run off status.

The Company offers a variety of consumer loan products including indirect auto, home equity and other consumer loans. Indirect auto loans include indirect installment loans to individuals, which
are primarily secured by automobiles. Although automobile loans have generally been originated through dealers, all applications submitted through dealers are subject to the Company’s normal underwriting and loan approval procedures. Other
consumer loans consist of direct installment loans to individuals most secured by automobiles and other personal property and unsecured consumer loans across a national footprint originated through our relationship with national
technology-driven consumer lending companies that began over 10 years ago beginning with our investment in Springstone Financial LLC (“Springstone”) which was subsequently acquired by LendingClub in 2014. Springstone and LendingClub loans are
in a planned run-off status. In addition to installment loans, the Company also offers personal lines of credit, overdraft protection, home equity lines of credit and second mortgage loans (loans secured by a lien position on one-to-four family
residential mortgage) to finance home improvements, debt consolidation, education and other uses. For home equity loans, consumers are able to borrow up to 85% of the equity in their homes, and are generally tied to Prime with a ten year draw
followed by a fifteen year amortization.

Loans by Maturity and Interest Rate Sensitivity

The following table presents the maturity distribution and an analysis of loans that have predetermined and floating interest rates. Scheduled repayments are reported in the maturity category in
which the contractual maturity is due. For loans without contractual maturities, classification of maturity is consistent with the policy elections to measure the allowance for credit losses. Specifically, C&I and CRE lines of credit assume
one year maturity for relationships over $1.0 million and five year maturity for relationships under $1.0 million, while home equity line of credits maturities are classified based on their fixed rate conversion date plus five years. C&I
includes PPP and other consumer includes home equity and other consumer loans.

Table of Contents

The following table sets forth information with regard to contractual maturities of debt securities shown in amortized cost ($) and weighted average yield (%) at December 31, 2025.
Weighted-average yields are an arithmetic computation of income (not FTE adjusted) divided by amortized cost. Maturities of mortgage-backed, collateralized mortgage obligations and asset-backed securities are stated based on their estimated
average lives. Actual maturities may differ from estimated average lives or contractual maturities because, in certain cases, borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

Funding Sources and Corresponding Interest Expense

The Company utilizes traditional deposit products such as time, savings, interest-bearing checking, money market and demand deposits as its primary source for funding. Other sources, such as
short-term FHLB advances, federal funds purchased, securities sold under agreements to repurchase, brokered time deposits and long-term FHLB borrowings are utilized as necessary to support the Company’s growth in assets and to achieve interest
rate sensitivity objectives. The average balance of interest-bearing liabilities totaled $9.57 billion in 2025 and increased $1.19 billion from 2024. The increase was primarily driven by the interest-bearing deposits acquired from Evans
partially offset by a decrease in short-term borrowings and subordinated debt. The rate paid on interest-bearing liabilities decreased from 2.52% in 2024 to 2.19% in 2025. This decrease in rates caused a decrease in interest expense of $2.1
million, or 1.0%, from $211.5 million in 2024 to $209.4 million in 2025.

Deposits

Average interest-bearing deposits increased $1.30 billion, or 16.5%, from 2024 to 2025. Average money market deposits increased $595.2 million, or 18.0%, during 2025 compared to 2024. Average
interest-bearing checking deposits increased $318.5 million, or 19.7%, during 2025 as compared to 2024. The average balance of savings accounts increased $243.4 million, or 15.4%, during 2025 compared to 2024. The average balance of time
deposits increased $146.6 million, or 10.4%, from 2024 to 2025. The average balance of demand deposits increased $303.8 million, or 9.0%, during 2025 compared to 2024. The increase in average balances was primarily due to the $1.86 billion in
deposits acquired from Evans in the second quarter of 2025. The Company’s composition of total deposits is diverse and granular with over 613,000 accounts with an average per account balance of $22,014 as of December 31, 2025.

The rate paid on average interest-bearing deposits was down 27 bps to 2.09% for 2025. The rate paid for MMDA decreased 59 bps to 2.95% from 2024 to 2025. The rate paid for interest-bearing
checking deposits increased from 0.83% in 2024 to 1.02% in 2025. The rate paid for savings deposits increased from 0.05% in 2024 to 0.33% in 2025. The rate paid for time deposits decreased from 3.96% during 2024 to 3.30% during 2025.

Borrowings

Average federal funds purchased decreased to $4.1 million in 2025. The rate paid on federal funds purchased was 4.50% in 2025. Average repurchase agreements increased to $114.8 million in 2025
from $95.9 million in 2024. The average rate paid on repurchase agreements increased from 2.35% in 2024 to 2.66% in 2025. Average short-term borrowings decreased to $8.7 million in 2025 from $104.0 million in 2024. The average rate paid on
short-term borrowings decreased from 5.48% in 2024 to 4.62% in 2025. Average long-term debt increased from $29.7 million in 2024 to $36.9 million in 2025. The average balance of junior subordinated debt increased from $101.2 million in 2024 to
$108.1 million in 2025. The average rate paid for junior subordinated debt in 2025 was 6.59%, down from 7.44% in 2024.

Total short-term borrowings consist of federal funds purchased, securities sold under repurchase agreements, which generally represent overnight borrowing transactions and other short-term
borrowings, primarily FHLB advances, with original maturities of one year or less. The Company has unused lines of credit with the FHLB and access to brokered deposits available for short-term financing. Those sources totaled approximately
$4.38 billion and $3.46 billion at December 31, 2025 and 2024, respectively. Securities collateralizing repurchase agreements are held in safekeeping by nonaffiliated financial institutions and are under the Company’s control. Long-term debt,
which is comprised primarily of FHLB advances, are collateralized by the FHLB stock owned by the Company, certain of its mortgage-backed securities and a blanket lien on its residential mortgage loans.

On June 23, 2020, the Company issued $100.0 million of 5.00% fixed-to-floating rate subordinated notes due 2030. The subordinated notes, which qualified as Tier 2 capital, bore interest at an annual
rate of 5.00%, payable semi-annually in arrears commencing on January 1, 2021, and a floating rate of interest equivalent to the three-month SOFR plus a spread of 4.85%, payable quarterly in arrears commencing on October 1, 2025. The subordinated
notes issuance costs of $2.2 million were amortized on a straight-line basis into interest expense over five years. The Company repurchased $2.0 million of the subordinated notes in 2022 at a discount of $0.1 million. On July 1, 2025, the Company
redeemed these subordinated notes in full using existing liquidity sources.

The subordinated notes assumed in connection with the Salisbury acquisition included $25.0 million of 3.50% fixed-to-floating rate subordinated notes due 2031. The subordinated notes, which
qualified as Tier 2 capital, bore interest at an annual rate of 3.50%, payable quarterly in arrears commencing on June 30, 2021, and a floating rate of interest equivalent to the three-month SOFR plus a spread of 2.80%, payable quarterly in
arrears commencing on June 30, 2026. As of the acquisition date, the fair value discount was $3.0 million, which will be amortized into interest expense over the expected call or maturity date.

Subordinated notes assumed in connection with the Evans acquisition included $20.0 million of 6.00% fixed-to-floating rate subordinated notes due 2030. The subordinated notes, which qualified as
Tier 2 capital, bore interest at an annual rate of 6.00%, payable semi-annually in arrears commencing on January 15, 2021, and a floating rate of interest equivalent to the three-month SOFR plus a spread of 5.90%, payable quarterly in arrears
commencing on July 15, 2025. On July 15, 2025, the Company redeemed these subordinated notes in full using existing liquidity sources.

As of December 31, 2025 and December 31, 2024 the subordinated debt net of unamortized issuance costs and fair value discount was $24.5 million and $121.2 million, respectively.

Noninterest income for the year ended December 31, 2025 was $195.5 million, up $18.7 million, or 10.6%, from the year ended December 31, 2024. Excluding net securities gains (losses), noninterest income for the
year ended December 31, 2025 was $195.3 million, up $21.3 million, or 12.2%, from the year ended December 31, 2024. The increase from the prior year was primarily due to an increase in retirement plan administration
fees, wealth management fees and bank owned life insurance income. The increase in retirement plan administration fees was driven by higher market values of assets under administration, organic growth and the acquisition of a small TPA business
in the fourth quarter of 2024. The increase in wealth management fees was driven by market performance and growth in new customer accounts. Bank owned life insurance income increased due to $2.7 million in additional gains recognized in 2025.
Service charges on deposit accounts, card services income and other noninterest income increased from 2024 primarily due to the Evans acquisition. Included in other noninterest income for the year ended December 31, 2025 was a $0.6 million gain
related to the finalization of a third-party contractual arrangement.

In the first quarter of 2023, the Company incurred a $5.0 million securities loss on the write-off of an AFS subordinated debt investment of a failed financial institution. In the first quarter of
2024, the Company sold the previously written-off subordinated debt security and recognized a gain of $2.3 million. In the second quarter of 2023, the Company incurred a $4.5 million securities loss on the sale of two subordinated debt securities
held in the AFS portfolio. In the fourth quarter of 2023 the Company recorded a full $4.8 million impairment of its minority interest equity investment in a provider of financial and technology services to residential solar equipment installers
due to the uncertainty in the realizability of the investment in other noninterest expense in the consolidated statements of income.

for the year ended December 31, 2025 was $425.8 million, up $49.5 million, or 13.1%, from the year ended December 31, 2024. The increase from the prior year was driven by higher salaries and employee benefits due to the Evans acquisition, merit
pay increases, higher incentive compensation expenses and higher medical expenses and other benefit costs. The increase in technology and data services was driven by the Evans acquisition and ongoing investment in enterprise technology
initiatives. Occupancy expense was impacted by additional expenses from the Evans acquisition, higher utilities and higher facilities costs related to new branch banking locations. Professional fees and outside services increased from the prior
year primarily due to the Evans acquisition. In addition, the increase in amortization of intangible assets was due to the amortization of the core deposit intangible asset related to the Evans acquisition.

Income Taxes

We calculate our current and deferred tax provision based on estimates and assumptions that could differ from the actual results reflected in income tax returns filed during the subsequent year.
Adjustments based on filed returns are recorded when identified, which is generally in the fourth quarter of the subsequent year for U.S. federal and state provisions.

The amount of income taxes the Company pays is subject at times to ongoing audits by U.S. federal and state tax authorities, which may result in proposed assessments. Future results may include
favorable or unfavorable adjustments to the estimated tax liabilities in the period the assessments are proposed or resolved or when statutes of limitations on potential assessments expire. As a result, the Company’s effective tax rate may
fluctuate significantly on a quarterly or annual basis.

Income tax expense for the year ended December 31, 2025 was $50.2 million, up $11.4 million, or 29.3%, from the year ended December 31, 2024. The effective tax rate was 22.9% in 2025 and was 21.6% in 2024. The
increase in the effective tax rate from 2024 was primarily due to the higher level of pretax income and the impact of certain nondeductible acquisition expenses related to the Evans acquisition.

On July 4, 2025, the One Big Beautiful Bill Act (the “Bill”) was enacted into law. The significant provisions of the Bill include the permanent extension and modification of certain provisions of
the Tax Cuts and Jobs Act, including international tax provisions. The Bill also imposes a floor on tax deductions taken on charitable contributions. The legislation has multiple effective dates, with certain provisions effective in 2025 and
others implemented in later years. The provisions of the Bill are not expected to have a material impact on our consolidated financial statements.

Risk Management – Credit Risk

Credit risk is managed through a network of loan officers, credit committees, loan policies and oversight from senior credit officers and the Board. Management follows a policy of continually
identifying, analyzing and grading credit risk inherent in each loan portfolio. An ongoing independent review of individual credits in the commercial loan portfolio is performed by the independent loan review function. These components of the
Company’s underwriting and monitoring functions are critical to the timely identification, classification and resolution of problem credits.

Allowance for Credit Losses

Management considers the accounting policy relating to the allowance for credit losses to be a critical estimate given the degree of judgment exercised in evaluating the level of the allowance
required to estimate expected credit losses over the expected contractual life of our loan portfolio and the material effect that such judgments can have on the consolidated results of operations.

The CECL methodology requires an estimate of the credit losses expected over the life of a loan (or pool of loans). The allowance for credit losses is a valuation account that is deducted from, or
added to, the loans’ amortized cost basis to present the net, lifetime amount expected to be collected on the loans. Loan losses are charged off against the allowance when management believes a loan balance is confirmed to be uncollectible.
Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off.

Required additions or reductions to the allowance for credit losses are made periodically by charges or credits to the provision for loan losses. These are necessary to maintain the allowance at a
level which management believes is reasonably reflective of the overall loss expected over the contractual life of the loan portfolio, adjusted for expected prepayments and curtailments. While management uses available information to recognize
losses on loans, additions or reductions to the allowance may fluctuate from one reporting period to another. These fluctuations are reflective of changes in risk associated with portfolio content and/or changes in management’s assessment of
any or all of the determining factors discussed above. Management considers the allowance for credit losses to be appropriate based on evaluation and analysis of the loan portfolio.

Management estimates the allowance for credit losses using relevant available information, from internal and external sources, related to past events, current conditions, and reasonable and
supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Company historical loss experience was supplemented with peer information when there was insufficient loss data for the
Company. Significant management judgment is required at each point in the measurement process.

Table of Contents

The allowance for credit losses is measured on a collective (pool) basis, with both a quantitative and qualitative analysis that is applied on a quarterly basis, when similar risk characteristics
exist. The respective quantitative allowance for each segment is measured using an econometric, discounted PD and LGD modeling methodology in which distinct, segment-specific multi-variate regression models are applied to multiple,
probabilistically weighted external economic forecasts. Under the discounted cash flows methodology, expected credit losses are estimated over the effective life of the loans by measuring the difference between the net present value of modeled
cash flows and amortized cost basis. After quantitative considerations, management applies additional qualitative adjustments so that the allowance for credit loss is reflective of the estimate of lifetime losses that exist in the loan
portfolio as of the balance sheet date.

Portfolio segment is defined as the level at which an entity develops and documents a systematic methodology to determine its allowance for credit losses. Consistent with CECL guidance, management
has pooled loans with similar risk characteristics and identified segments for estimating loss based on type of borrower and collateral which is generally based upon federal call report segmentation and have been combined or subsegmented as
needed to ensure loans of similar risk profiles are appropriately pooled.

During the first quarter of 2025, the Company performed an annual update to its econometric, PD/LGD models. Segment specific, multi-variate regression model inputs and assumptions were updated and
recent period observed losses and behavior were incorporated into the models (“model refreshment”). The incorporation of recent observations did not have a material impact on most loan class segments except for the Auto class segment which
resulted in an improvement in PD/LGD outcomes. The total allowance decreased by approximately 3% as of March 31, 2025 due to the model refreshment. Starting in the second quarter of 2025, the Company included an additional downside scenario with
stagflation conditions, which is characterized as an economic environment where inflation rises alongside unemployment. Stagflation was identified as an emerging risk as tariff policies impacted the economy.

Additional information about our Allowance for Credit Losses is included in Notes 1 and 6 to the consolidated financial statements as well as in the “Critical Accounting Estimates” section of the
Management’s Discussion and Analysis of Financial Condition and Results of Operations. The Company’s management considers the allowance for credit losses to be appropriate based on evaluation and analysis of the loan portfolio.

Beginning January 1, 2023, the Company adopted ASU 2022-02 Financial Instruments - CECL Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”), which resulted in
an insignificant change to the Company’s methodology for estimating the allowance for credit losses on TDRs since December 31, 2022. The January 1, 2023 decrease in allowance for credit loss on TDR loans relating to adoption of ASU 2022-02 was
$0.6 million, which increased retained earnings by $0.5 million and decreased the deferred tax asset by $0.1 million.

The allowance for credit losses totaled $138.0 million at December 31, 2025, compared to $116.0 million at December 31, 2024. The allowance for credit losses as a percentage of loans was 1.19% at
December 31, 2025, compared to 1.16% at December 31, 2024. The increase in the allowance for credit losses from December 31, 2024 to December 31, 2025 was primarily due to the recording of $20.7 million of allowance for acquired Evans loans as of
the acquisition date, which included both $13.0 million of non-PCD allowance recognized through the provision for loan losses and the $7.7 million of PCD allowance reclassified from loans. In addition, the allowance for credit losses increased
due to deterioration in the economic forecast including the change in the forecast scenarios and weightings, partially offset by the shift in loan composition driven by other consumer and residential solar portfolios that are in a planned run-off
status.

The allowance for credit losses as of December 31, 2023 incorporates the recording of $14.5 million of allowance for acquired Salisbury loans as of the acquisition date, which included both the
$8.8 million of non-PCD allowance recognized through the provision for loan losses and the $5.8 million of PCD allowance reclassified from loans.

The allowance for credit losses was 266.81% of nonperforming loans at December 31, 2025 as compared to 224.73% at December 31, 2024.

The provision for loan losses was $32.3 million for the year ended December 31, 2025, compared to $19.6 million for the year ended December 31, 2024. Provision expense increased from the prior year
primarily due to the $13.0 million of acquisition-related provision for loan losses for non-PCD loans acquired from Evans and a deterioration in economic forecasts. Net charge-offs totaled $18.0 million for 2025 and 2024. Net charge-offs to
average loans was 16 bps for 2025 compared to 18 bps for 2024.

Nonperforming Assets

Nonperforming assets consist of nonaccrual loans, loans over 90 days past due and still accruing, troubled loans modifications, OREO and nonperforming securities. Loans are generally placed on
nonaccrual when principal or interest payments become 90 days past due, unless the loan is well secured and in the process of collection. Loans may also be placed on nonaccrual when circumstances indicate that the borrower may be unable to meet
the contractual principal or interest payments. The threshold for evaluating commercial loans risk graded substandard or doubtful, and nonperforming loans specifically evaluated for individual credit loss is $1.0 million. OREO represents
property acquired through foreclosure and is valued at the lower of the carrying amount or fair value, less any estimated disposal costs.

TDRs prior to adoption of ASU 2022-02.

Total nonperforming assets were $52.1 million at December 31, 2025, compared to $51.8 million at December 31, 2024. Nonperforming loans at December 31, 2025 were $51.7 million or 0.45% of total
loans, compared with $51.6 million or 0.52% of total loans at December 31, 2024. The increase in nonperforming assets from the prior year was primarily attributable to the addition of nonperforming loans acquired from the Evans acquisition, an
increase in loans 90 days or more past due and an increase in OREO, partially offset by a decrease in nonaccrual loans. Total nonaccrual loans were $44.6 million or 0.38% of total loans at December 31, 2025, compared to $45.8 million or 0.46%
of total loans at December 31, 2024. Past due loans as a percentage of total loans was 0.38% at December 31, 2025, up from 0.34% of total loans at December 31, 2024.

Table of Contents

In addition to nonperforming loans discussed above, the Company has also identified approximately $271.8 million in potential problem loans at December 31, 2025, as compared to $116.1 million at
December 31, 2024. Potential problem loans are loans that are currently performing, with a possibility of loss if weaknesses are not corrected. Such loans may need to be disclosed as nonperforming at some time in the future. Potential problem
loans are classified by the Company’s loan rating system as “substandard.” The increase in potential problem loans at December 31, 2025, compared to December 31, 2024 is primarily due to the addition of $60.5 million in acquired commercial
loans from Evans during the second quarter of 2025 and the net migration of commercial loan balances to substandard, the majority of which are adequately secured by the underlying real estate collateral. The increase in potential problem loans
is due to a convergence of macroeconomic pressures, post-pandemic credit normalization, higher interest rate repricing, and structural shifts in key industries. Management cannot predict the extent to which economic conditions may worsen or
other factors, which may impact borrowers and the potential problem loans. Accordingly, there can be no assurance that other loans will not become over 90 days past due, be placed on nonaccrual, become troubled loans modifications or require
increased allowance coverage and provision for loan losses. To mitigate this risk the Company maintains a diversified loan portfolio, has no significant concentration in any particular industry and originates loans primarily within its
footprint.

Allowance for Credit Losses on Off-Balance Sheet Credit Exposures

The Company estimates expected credit losses over the contractual period in which the Company has exposure to credit risk via a contractual obligation to extend credit, unless that obligation is
unconditionally cancellable by the Company. The allowance for losses on off-balance sheet credit exposures is adjusted as an expense in other noninterest expense. The estimate includes consideration of the likelihood that funding will occur and
an estimate of expected credit losses on commitments expected to be funded over their estimated lives. The allowance for credit losses on unfunded commitments totaled $5.8 million as of December 31, 2025, compared to $4.4 million as of December
31, 2024. December 31, 2025 included $0.5 million of acquisition-related provision for unfunded loan commitments. The increase from prior year was primarily related to increases in pipeline exposure and the Evans acquisition.

Liquidity Risk

Liquidity risk arises from the possibility that the Company may not be able to satisfy current or future financial commitments or may become unduly reliant on alternate funding sources. The
objective of liquidity management is to ensure the Company can fund balance sheet growth, meet the cash flow requirements of depositors wanting to withdraw funds or borrowers needing assurance that sufficient funds will be available to meet
their credit needs. ALCO is responsible for liquidity management and has developed guidelines, which cover all assets and liabilities, as well as off-balance sheet items that are potential sources or uses of liquidity. Liquidity policies must
also provide the flexibility to implement appropriate strategies, along with regular monitoring of liquidity and testing of the contingent liquidity plan. Requirements change as loans grow, deposits and securities mature and payments on
borrowings are made. Liquidity management includes a focus on interest rate sensitivity management with a goal of avoiding widely fluctuating net interest margins through periods of changing economic conditions. Loan repayments and maturing
investment securities are a relatively predictable source of funds. However, deposit flows, calls of investment securities and prepayments of loans and mortgage-related securities are strongly influenced by interest rates, the housing market,
general and local economic conditions, and competition in the marketplace. Management continually monitors marketplace trends to identify patterns that might improve the predictability of the timing of deposit flows or asset prepayments.

The primary liquidity measurement the Company utilizes is called “Basic Surplus,” which captures the adequacy of its access to reliable sources of cash relative to the stability of its funding mix
of average liabilities. This approach recognizes the importance of balancing levels of cash flow liquidity from short and long-term securities with the availability of dependable borrowing sources, which can be accessed when necessary. At
December 31, 2025, the Company’s Basic Surplus measurement was 18.7% of total assets, or $2.98 billion, as compared to the December 31, 2024 Basic Surplus of 17.0%, or $2.34 billion, and was above the Company’s minimum of 5% (calculated at
$799.8 million and $689.3 million of period end total assets as of December 31, 2025 and December 31, 2024, respectively) set forth in its liquidity policies.

respectively, of collateral encumbered by municipal letters of credit. The Bank is a member of the FHLB system and had additional borrowing capacity from the FHLB of approximately $2.10 billion at December 31, 2025 and $1.71 billion at December
31, 2024. In addition, unpledged securities could have been used to increase borrowing capacity at the FHLB by an additional $1.11 billion and $957.3 million at December 31, 2025 and 2024, respectively, or used to collateralize other
borrowings, such as repurchase agreements. The Company also has the ability to issue brokered time deposits and to borrow against established borrowing facilities with other banks (federal funds), which could provide additional liquidity of
$2.53 billion and $2.01 billion at December 31, 2025 and December 31, 2024, respectively. In addition, the Bank has a “Borrower-in-Custody” program with the FRB with the addition of the ability to pledge automobile and residential solar loans
as collateral. At December 31, 2025 and 2024, the Bank had the capacity to borrow $1.18 billion and $1.13 billion, respectively, from this program. The Company’s internal policies authorize borrowing up to 25% of assets. Under this policy,
remaining available borrowing capacity totaled $3.94 billion at December 31, 2025 and $3.38 billion at December 31, 2024.

This Basic Surplus approach enables the Company to appropriately manage liquidity from both operational and contingency perspectives. By tempering the need for cash flow liquidity with reliable
borrowing facilities, the Company is able to operate with a more fully invested and, therefore, higher interest income generating securities portfolio. The makeup and term structure of the securities portfolio is, in part, impacted by the
overall interest rate sensitivity of the balance sheet. Investment decisions and deposit pricing strategies are impacted by the liquidity position. The Company considers its Basic Surplus position to be strong. However, certain events may
adversely impact the Company’s liquidity position in 2026. While short-term interest rates have declined, they remain elevated relative to recent history, which could result in deposit declines as depositors have alternative opportunities for
yield on their excess funds. In the current economic environment, draws against lines of credit could drive asset growth higher. Disruptions in wholesale funding markets could spark increased competition for deposits. These scenarios could lead
to a decrease in the Company’s Basic Surplus measure below the minimum policy level of 5%. Note, enhanced liquidity monitoring was put in place to quickly respond to the changing environment during the pandemic including increasing the
frequency of monitoring and adding additional sources of liquidity. While the pandemic has come to an end, this enhanced monitoring continues as elevated interest rates and the bank failures of 2023 have led to a deposit decline in the banking
system and increased volatility to liquidity risk.

At December 31, 2025, a portion of the Company’s loans and securities were pledged as collateral on borrowings. Therefore, once on-balance sheet liquidity is reduced, future growth of earning
assets will depend upon the Company’s ability to obtain additional funding, through growth of core deposits and collateral management and may require further use of brokered time deposits or other higher cost borrowing arrangements.

Net cash flows provided by operating activities totaled $235.2 million and $188.6 million in 2025 and 2024, respectively. The critical elements of net operating cash flows include net income,
adjusted for non-cash income and expense items such as the provision for loan losses, deferred income tax expense, depreciation and amortization and cash flows generated through changes in other assets and liabilities.

Net cash flows provided by investing activities totaled $169.1 million in 2025 and net cash flows used in investing activities totaled $399.2 million in 2024. Critical elements of investing
activities are loan and investment securities transactions.

Net cash flows used in financing activities totaled $201.2 million in 2025 and net cash flows provided by financing activities totaled $289.5 million in 2024. The critical elements of financing
activities are proceeds from deposits, borrowings and stock issuance. In addition, financing activities are impacted by dividends and treasury stock transactions.

Commitments to Extend Credit

The Company makes contractual commitments to extend credit, which include unused lines of credit, which are subject to the Company’s credit approval and monitoring procedures. At December 31, 2025
and 2024, commitments to extend credit in the form of loans, including unused lines of credit, amounted to $3.40 billion and $2.84 billion, respectively. In the opinion of management, there are no material commitments to extend credit,
including unused lines of credit that represent unusual risks. All commitments to extend credit in the form of loans, including unused lines of credit, expire within one year.

Standby Letters of Credit

The Company does not issue any guarantees that would require liability-recognition or disclosure, other than its standby letters of credit. The Company guarantees the obligations or performance of
customers by issuing standby letters of credit to third-parties. These standby letters of credit are generally issued in support of third-party debt, such as corporate debt issuances, industrial revenue bonds and municipal securities. The risk
involved in issuing standby letters of credit is essentially the same as the credit risk involved in extending loan facilities to customers and letters of credit are subject to the same credit origination, portfolio maintenance and management
procedures in effect to monitor other credit and off-balance sheet products. Typically, these instruments have one year expirations with an option to renew upon annual review; therefore, the total amounts do not necessarily represent future
cash requirements. At December 31, 2025 and 2024, standby letters of credit were $58.5 million and $50.8 million, respectively. As of December 31, 2025 and 2024, the fair value of the Company’s standby letters of credit was not significant. The
following table sets forth the commitment expiration period for standby letters of credit at:

Interest Rate Swaps

The Company records all derivatives on the consolidated balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative,
whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting.

When the Company purchases or sells a portion of a commercial loan that has an existing interest rate swap, it may enter into a risk participation agreement to provide credit protection to the
financial institution that originated the swap transaction should the borrower fail to perform on its obligation. The Company enters into both risk participation agreements in which it purchases credit protection from other financial
institutions and those in which it provides credit protection to other financial institutions. Any fee paid to the Company under a risk participation agreement is in consideration of the credit risk of the counterparties and is recognized in
the income statement. Credit risk on the risk participation agreements is determined after considering the risk rating, PD and LGD of the counterparties.

Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk, such as interest rate risk,
are considered fair value hedges. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or if the Company elects not to apply hedge accounting.

For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings.

Loans Serviced for Others and Loans Sold with Recourse

The total amount of loans serviced by the Company for unrelated third parties was $1.28 billion and $982.5 million at December 31, 2025 and 2024, respectively. At December 31, 2025 and 2024, the
Company had $2.1 million and $0.9 million, respectively, of mortgage servicing rights.

At December 31, 2025 and 2024, the Company serviced $23.2 million and $24.7 million, respectively, of agricultural loans sold with recourse. Due to sufficient collateral on these loans and
government guarantees, no reserve is considered necessary at December 31, 2025 and 2024.

Capital Resources

Consistent with its goal to operate a sound and profitable financial institution, the Company actively seeks to maintain a “well capitalized” institution in accordance with regulatory standards.
The principal source of capital to the Company is earnings retention. Capital measurements are well in excess of regulatory minimum guidelines and meet the requirements to be considered well capitalized.

The Company’s primary source of funds is dividends from its subsidiaries. Various laws and regulations restrict the ability of banks to pay dividends to their stockholders. Generally, the payment
of dividends by the Company in the future as well as the payment of interest on the capital securities will require the generation of sufficient future earnings by its subsidiaries.

Certain restrictions exist regarding the ability of the Bank to transfer funds to the Company in the form of cash dividends. The approval of the OCC is required to pay dividends when a bank fails
to meet certain minimum regulatory capital standards or when such dividends are in excess of a subsidiary bank’s earnings retained in the current year plus retained net profits for the preceding two years as specified in applicable OCC
regulations. At December 31, 2025 and 2024, approximately $115.9 million and $107.6 million, respectively, of the total stockholders’ equity of the Bank was available for payment of dividends to the Company without approval by the OCC. The
Bank’s ability to pay dividends is also subject to the Bank being in compliance with regulatory capital requirements. The Bank is currently in compliance with these requirements. Under the State of Delaware General Corporation Law, the Company
may declare and pay dividends either out of accumulated net retained earnings or capital surplus.

Stock Repurchase Plan

On October 27, 2025, the Company’s Board of Directors authorized and approved an amendment to the Company’s stock repurchase program. Pursuant to the amended stock repurchase program, the Company
may repurchase up to 2,000,000 shares of the Company’s common stock with all repurchases under the stock repurchase program to be made by December 31, 2027. The Company may repurchase shares of its common stock from time to time to mitigate the
potential dilutive effects of stock-based incentive plans and other potential uses of common stock for corporate purposes.

The Company purchased 250,000 shares of its common stock during the year ended December 31, 2025, for a total of $10.2 million at an average price of $40.74 per share under its previously announced
share repurchase program. As of December 31, 2025, there were 1,750,000 shares available for repurchase under this plan authorized on October 27, 2025 which is set to expire on December 31, 2027.
