Enact Holdings, Inc. (ACT) Business

Item 1. Business

Overview

We are a leading private mortgage insurance company serving the United States housing finance market since 1981 with a mission to help people buy a house and keep it their home. We operate in all 50 states and the District of Columbia. Our principal mortgage insurance customers are originators of residential mortgage loans who typically determine which mortgage insurer or insurers they will use for the placement of mortgage insurance written on loans they originate.

As a private mortgage insurer, we play a critical role in the United States housing finance system. We are engaged in the business of writing and assuming residential mortgage guaranty insurance. The insurance covers a portion of the unpaid principal balance of Low Down Payment Loans (mortgage loans where the loan amount exceeds 80% of the value of the home) and protects lenders and investors against certain losses resulting from nonpayment of loans secured by mortgages, deeds of trust, or other instruments constituting a first lien on residential real estate. We facilitate the sale of mortgages to the secondary market, including to private investors as well as the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). Fannie Mae and Freddie Mac are government-sponsored enterprises (collectively referred to as the “GSEs”). Credit protection and liquidity through secondary market sales allow mortgage lenders to increase their lending capacity, manage risk and expand financing access to prospective homeowners, many of whom are first time home buyers (“FTHBs”).

We have a large and diverse customer base and maintain enduring relationships across the mortgage origination market, including with national banks, non-bank mortgage lenders, local mortgage bankers, community banks and credit unions. In 2025, we provided new insurance coverage to approximately 1,600 customers. For the full years ended December 31, 2025, 2024 and 2023 we generated new insurance written (“NIW”) of $51.5 billion, $51.0 billion and $53.1 billion, respectively. Net income was $674 million, $688 million and $666 million in 2025, 2024 and 2023, respectively. Adjusted operating income was $688 million, $718 million and $676 million for 2025, 2024 and 2023, respectively.

We have a rigorous approach to writing new insurance risk based on decades of loan-level data and experience in the mortgage insurance industry. Our balance sheet is well capitalized to manage through macroeconomic uncertainty and maintain compliance with private mortgage insurer eligibility requirements (“PMIERs”) and state regulatory standards of compliance. We utilize our credit risk transfer (“CRT”) program to mitigate future loss volatility and drive efficient capital management. Our CRT program is a material component of our strategy, and we believe it helps to protect future business performance and stockholder capital under stress scenarios by transferring risk from our balance sheet to highly rated counterparties or to investors through collateralized transactions.

Our Industry

United States Mortgage Market

The United States residential mortgage market is one of the largest in the world and includes a range of private and government-sponsored participants. Private industry participants include mortgage banks, mortgage brokers, commercial, regional and investment banks, savings institutions, credit unions, real estate investment trusts, mortgage insurers and the GSEs. The overall United States residential mortgage market encompasses both primary and secondary markets. The primary market consists of lenders originating home loans to borrowers to support home purchases, which are referred to as purchase originations, and loans made to refinance existing mortgages, which are referred to as refinancing originations. The secondary market includes institutions buying and selling mortgages in the form of whole loans or securitized assets, such as mortgage-backed securities (“MBS”).

GSEs

The GSEs are the largest participants in the secondary mortgage market, buying residential mortgages from banks and other primary lenders as part of their government mandate to provide access, liquidity and stability in the United States housing finance system. According to the earnings reports of the GSEs, the GSEs held or guaranteed approximately $7.8 trillion as of September 30, 2025, or around 53%, of total United States 1-4 family residential mortgage debt according to most recent data from the Federal Reserve. The GSE charters generally require credit enhancement for Low Down Payment Loans to be eligible for purchase by the GSEs. Such credit enhancement can be satisfied if a loan is insured by a GSE-qualified insurer, the mortgage seller retains at least a 10% participation in the loan, or the seller agrees to repurchase or replace the loan in the event of a default. Private mortgage insurance satisfies the GSEs’ credit enhancement requirement and, historically, has been the preferred method lenders have utilized to meet this GSE charter requirement. As a result, the nature of the private mortgage insurance

5

industry in the United States is driven in large part by the business practices and mortgage insurance requirements of the GSEs. In furtherance of their respective charter requirements, each GSE maintains private mortgage insurer eligibility criteria, known as PMIERs, to establish when a mortgage insurer is qualified to issue coverage that will be acceptable to the GSEs for their portfolio. For more information about the financial and other requirements of the GSEs, see “Item 1A. Risk Factors—Risks Relating to Our Business—If we are unable to continue to meet the requirements mandated by PMIERs, or any additional restrictions which may be imposed on us by the GSEs, we may not be eligible to write new insurance on loans acquired by the GSEs, which would have a material adverse effect on our business, results of operations and financial condition.”

Private Mortgage Insurance

Private mortgage insurance plays a critical role in the United States residential mortgage market by facilitating secondary market sales, particularly for Low Down Payment Loans. This credit protection and the resulting liquidity it provides through secondary market sales allows mortgage lenders to increase their lending capacity, manage risk and expand prospective homeowners’ access to financing, many of whom are FTHBs. Mortgage insurance also provides lenders and investors a means to diversify their exposures, mitigate mortgage credit risk and may offer credit against regulatory capital requirements to certain financial institutions that portfolio Low Down Payment Loans. Today, mortgage insurance products are primarily geared towards GSE secondary market sales. The increase in penetration of private mortgage insurance in the mortgage market can be attributed to both the introduction of new GSE products designed to serve Low Down Payment Loan borrowers and more competitive pricing by private mortgage insurers relative to the Federal Housing Administration (“FHA”). In addition, there are potential opportunities for the demand for and use of mortgage insurance to the extent that the private label securitization market expands in the future.

The overall new business opportunity in the private mortgage insurance market is also reflective of the mix between purchase and refinancing originations. Historically, due to the higher prevalence of Low Down Payment Loans in purchase originations, mortgage insurance utilization has been meaningfully higher for purchase originations than for refinances.

Competition

Our principal sources of competition are government (federal, state and local) agencies, such as the FHA and the United States Department of Veterans Affairs (“VA”) and other private mortgage insurers. We also compete with mortgage lenders and other investors, the GSEs, portfolio lenders who self-insure, reinsurers and other capital markets participants who may utilize financial instruments designed to mitigate risk.

Federal, State and Local Government Agencies

Private mortgage insurers, including the Company, compete for mortgage insurance business directly with federal government agencies, principally the FHA and the VA, and, to a lesser extent, state and local housing finance agencies. According to Inside Mortgage Finance, for the first three quarters of 2025, the FHA had a 35% share, and the VA a 26% share, of the mortgage insurance market. Our competition with government agencies is principally on the basis of price and underwriting guidelines. In contrast to private mortgage insurers, government agencies generally have less restrictive guidelines and apply a flat pricing structure regardless of an individual borrower’s credit profile. As a result, we believe borrowers with lower Fair Isaac Company (“FICO”) scores are more likely to secure mortgage loans with coverage by public agencies and borrowers with higher FICO scores are more likely to secure mortgage loans with coverage by private mortgage insurers. Mortgage insurance policies from government agencies are also generally non-cancellable, meaning that borrowers are obligated to pay for coverage through the life of their loan, whereas policies from private mortgage insurers are cancellable in certain circumstances as provided by the Homeowners Protection Act of 1998 (“HOPA”), and under GSE guidelines when the loan-to-value

6

(“LTV”) ratio of an underlying mortgage falls below 80%. Private mortgage insurers also face limited competition from certain local and state housing finance agencies.

Private Mortgage Insurers

The United States private mortgage insurance industry is highly competitive. We compete on pricing, underwriting guidelines, customer relationships, service levels, policy terms, loss mitigation practices, perceived financial strength (including comparative credit ratings), reputation, strength of management, product features and effective use and ease of technology. There are currently six active private mortgage insurers, including us. Private mortgage insurance competitors include Arch Capital Group Ltd., Essent Group Ltd., MGIC Investment Corporation, NMI Holdings, Inc. and Radian Group Inc. (public holding companies of competitors listed). Since 2012, we have maintained between a 12.0% and 20.4% per quarter share of the private mortgage insurance market by per annum NIW, based on data from Inside Mortgage Finance.

GSEs, Portfolio Lenders, Reinsurers and Other Capital Markets Participants

We have also experienced competition from various participants in the mortgage finance industry including the GSEs, portfolio lenders, reinsurers and other participants in the capital markets. We compete with these participants primarily based on pricing, policy terms and perceived financial strength. The GSEs enter into risk sharing transactions with financial institutions designed to reduce the risk of their mortgage portfolios. Competition also comes from portfolio lenders that are willing to hold credit risk on their balance sheets without credit enhancement. In addition, investors can make use of risk-sharing structures designed to mitigate the impact of mortgage defaults in place of private mortgage insurance. Finally, although their presence is a fraction of what it was in the past, there are products designed to eliminate the need for private mortgage insurance, such as “simultaneous seconds,” which combine a first lien loan with a second lien loan in order to meet the 80% LTV threshold required for sale to the GSEs without certain credit protections.

Our Products and Services

In general, there are two types of private mortgage insurance: primary and pool.

Primary Mortgage Insurance

Substantially all of our policies are primary mortgage insurance, which provides protection on individual loans at specified coverage percentages. Primary mortgage insurance is placed on individual loans at the time of origination and are typically delivered to us on a loan-by-loan basis. Primary mortgage insurance can also be delivered to us on an aggregated basis, whereby each mortgage in a given loan portfolio is insured in a single transaction after the point of origination.

Customers who purchase our primary mortgage insurance select a specific coverage level for each insured loan. To be eligible for purchase by a GSE, a Low Down Payment Loan must comply with the coverage percentages established by that particular GSE. For loans not sold to the GSEs, the customer determines its desired coverage percentage. Generally, our risk across all policies written is approximately 25% of the underlying primary insurance in-force (“IIF”), but may vary from policy to policy, typically between 6% and 35% coverage.

We file our premium rates, as required, with insurance departments of U.S. States and the District of Columbia. Premium rates cannot be changed after the issuance of coverage. Premium payments for primary mortgage insurance coverage are typically made by the borrower and are referred to as borrower-paid mortgage insurance. Loans for which premiums are paid by the lender are referred to as lender-paid mortgage insurance. In either case, the payment of premium to us is generally the responsibility of the insured.

7

Premiums are generally calculated as a percentage of the original principal balance and may be paid as follows:

•Monthly, where premiums are paid on a monthly basis over the life of the policy;

•Single, where the entire premium is paid upfront at the time the mortgage loan is originated;

•Annually, where premiums are paid annually in advance for the subsequent 12 months; or

•Split, where an initial lump sum premium is paid upfront at the time the mortgage is originated along with subsequent monthly payments.

In general, we may not terminate mortgage insurance coverage except in the event of non-payment of premiums or certain material violations of our mortgage insurance policies. The insured may cancel mortgage insurance coverage at any time at their option or upon mortgage repayment, which is accelerated in the event of a refinancing. However, in the case of loans sold to the GSEs, lender cancellation of a policy not eligible for cancellation under GSE guidelines may be in violation of the GSEs’ respective charters. GSE guidelines generally provide that a borrower meeting certain conditions may require the mortgage servicer to cancel mortgage insurance coverage upon the borrower’s request when the principal balance of the loan is 80% or less of the property’s current value. In addition to the GSE guidelines, HOPA provides an obligation for lenders to automatically terminate a borrower’s obligation to pay for mortgage insurance coverage once the LTV ratio reaches 78% of the original value, and also provides that a borrower may request cancellation of their obligation to pay for mortgage insurance when the LTV ratio reaches 80% of the original value. In addition, some states impose their own mortgage insurance notice and cancellation requirements on mortgage loan servicers.

Pool Mortgage Insurance

Pool mortgage insurance transactions provide coverage on a finite set of individual loans identified by the pool policy. Pool policies contain coverage percentages and provisions limiting the insurer’s obligation to pay claims until a threshold amount is reached (known as a “deductible”) or capping the insurer’s potential aggregate liability for claims payments (known as a “stop loss”) or a combination of both provisions. Pool mortgage insurance is typically used to provide additional credit enhancement for certain secondary market mortgage transactions. Pool insurance generally covers the excess of the loss on a defaulted mortgage loan that exceeds the claim payment under the primary coverage, if such loan has primary coverage, as well as the total loss on a defaulted mortgage loan that did not have primary coverage. In another variation, generally referred to as modified pool insurance, policies are structured to include both an exposure limit for each individual loan, as well as an aggregate loss limit or a deductible for the entire pool. Currently, we have an insignificant amount of pool IIF.

Contract Underwriting Services

We also perform fee-based contract underwriting services for our customers. Contract underwriting provides our customers outsourced scalable capacity to underwrite mortgage loans. Our underwriters can underwrite the loan on behalf of our customers for both investor compliance and mortgage insurance, thus reducing duplicative activities and increasing our ability to write mortgage insurance for these loans. Under the terms of our contract underwriting agreements, we indemnify our customer against losses incurred in the event we make material errors in determining whether loans underwritten by our contract underwriters meet specified underwriting or purchase criteria, subject to contractual limitations on liability.

Our Mortgage Insurance Portfolio

We believe that our portfolio is of significant scale and aligns with our appetite for risk and return. The majority of our in-force exposures and all of our NIW is considered primary insurance, meaning we insure the loss on each loan up to the coverage amount without any stop loss or deductible for that loss. Our remaining pool exposures are significantly seasoned and represent only 0.1% of total risk in-force (“RIF”).

8

Our primary insurance portfolio is diversified through time. The distribution of our exposure by book year is influenced by market size opportunities, our commercial strategies and the persistency of our in-force policies. In 2021 and 2020, our portfolio was impacted by low persistency, a large origination market and commercial success in the market. A period of higher persistency followed, leading to a more balanced concentration of IIF in recent years. Our primary exposures from legacy books originated prior to 2009 continue to resolve in an orderly fashion and represented 2% of both our primary IIF and primary RIF as of December 31, 2025.

We measure the credit characteristics of our portfolio as represented in the original commitment for insurance. We support a growing FTHB segment that generally has little down payment saved for their first home and therefore higher LTV ratios. Generally, a higher LTV ratio has a higher likelihood of claim than a lower LTV loan, absent other mitigating loan characteristics, which we consider in our underwriting and pricing. The weighted average LTV of our IIF as of December 31, 2025 was 93% and the weighted average LTV of our NIW was 92% in 2025 and 93% in 2024.

The credit profile of our portfolio as represented by FICO score remains strong. Generally, a borrower with a higher FICO score has a lower likelihood of claim than one with a lower FICO score. The weighted average FICO score of our IIF as of December 31, 2025 was 746 and the weighted average FICO score of our NIW was 753 in 2025 and 751 in 2024.

Our portfolio is diverse and representative of the United States origination market. We actively monitor our portfolio for concentrations at the state, metropolitan statistical area and metropolitan division level in addition to economic and performance trends in these markets. As of December 31, 2025, our largest state concentration was in California, which represented 12% of primary RIF. Our largest Metropolitan Statistical Area (“MSA”) or Metro Division (“MD”) is the Phoenix, AZ, MSA, which represents 3% of primary RIF.

Customers

Our long-standing industry presence has enabled us to build active customer relationships with approximately 1,600 mortgage lenders across the United States. Our customers are broadly diversified by size, type and geography and include large money center banks, non-bank lenders, national and local mortgage bankers, community banks and credit unions. Our largest customer accounted for 22% of total NIW and 12% of our total revenues for the year ended December 31, 2025, 20% of total NIW and 11% of our total revenues for the year ended December 31, 2024, and 19% of total NIW and 10% of our total revenues for the year ended December 31, 2023. No other customer accounted for 10% or more of total revenues or NIW for the years ended December 31, 2025, 2024 or 2023. Our top five customers generated 33% of our NIW in 2025.

We believe that our success in establishing strong, sustained relationships and our ability to capture new customers is attributable to our comprehensive value proposition. We offer customers a competitive price along with differentiated offerings and services. Additionally, by maintaining an ongoing dialogue with our customers, we are able to develop an understanding of their needs, offer customized solutions for their challenges, advise them on portfolio composition and trends, share market perspectives and industry best practices and provide product development support and training as necessary.

Sales and Marketing

Our sales and marketing efforts are designed to help us establish and maintain in-depth, quality customer relationships. We distribute our mortgage insurance products through a dedicated sales force located throughout the United States, our inside sales representatives and a digital marketing program designed to expand our reach beyond our sales force. The breadth and depth of relationships across all areas of our customers’ operations serves as a differentiator for our mortgage insurance platform and also enables us to form strategic partnerships with other mortgage service providers seeking to expand their distribution reach.

9

We support our sales force and improve their effectiveness in acquiring new customers by raising our brand awareness through advertising and marketing campaigns, website enhancements, digital communication strategies and sponsorship of industry and educational events. Our digital marketing capabilities position us to serve our decentralized market with targeted, personalized messages that help drive a preference for our offering.

We also offer a separate mortgage insurance policy underwritten by our wholly owned subsidiary, Enact Mortgage Insurance Corporation of North Carolina (“EMIC-NC”), to insure primary individually underwritten residential mortgage loans as well as portfolios of residential mortgage loans at or after origination that are not intended for sale to the GSEs. As EMIC-NC is not a GSE approved insurer, it is not subject to the requirements mandated by PMIERs, providing us operating flexibility and strategic optionality if the private label MBS market increases.

Technology that supports connectivity with our customers is critical and we focus on our customer technology processes and integrations. We have long-standing relationships with the mortgage industry’s technology platforms and service providers, along with a technology integration team that allows us to quickly customize loan delivery solutions for our customers. Our customer technology program enables Enact to provide customers an easy way to quote and order our mortgage insurance products, either through our ordering and rate quote website or directly with their preferred systems.

Risk Management and Oversight

Strong risk management is a critical part of our business. The Risk Committee of our Board of Directors is responsible for oversight and review of our enterprise risk management policies and related risk profile. We believe our risk management framework is appropriately designed to manage volatility in our business performance and protect our balance sheet. We believe this framework encompasses all major risks to which we are exposed, including credit risk, market risk, insurance risk, housing risk, operational risk, model risk, IT risk, including cybersecurity risk, and any other risk that poses a material threat to the viability of the Company.

Our risk management philosophy is designed to ensure all relevant risks are routinely identified, assessed, managed, monitored and addressed. We rely upon a strong organizational risk culture and governance process, supporting that the risks we take are transparent and quantifiable, and that we can monitor the changing nature of those risks over time. We proactively work towards mitigating exposures outside of the risk appetite, limits and tolerances that we set and review annually. Our risk profile, top risks and any emerging risks are regularly reviewed in our senior management risk committee, chaired by our Chief Risk Officer who has direct reporting obligations to the Risk Committee of our Board.

Modeling and Analytics

We use our proprietary risk modeling platform to evaluate returns and volatility through both an external regulatory lens and an economic capital framework that is sensitive to the economic cycle and current housing market conditions. This risk model utilizes numerous predictive variables and leverages our unique data set, which contains experience of over two decades of mortgage performance across all market conditions, to develop quantitative assessments of default probability, severity of loss, prepayment and expected volatility on each insured loan. Our model is used to assess the performance of new business and our in-force portfolio under expected and stress scenarios. The results of these analyses inform our risk appetite, credit policy, pricing and targeted risk selection strategies. In addition, the results of these stress tests and our desire to reduce loss volatility inform our CRT strategy.

Customer Qualification

Customers applying for a new master policy undergo a process that reviews their business and financial profile, licensing, management experience and track record of originating quality mortgages. Customers applying for delegated underwriting authority receive training and are reviewed on initial and ongoing submissions for compliance with our guidelines.

10

Policy Acquisition

Loans delivered to us for insurance must meet our underwriting and eligibility guidelines. Our underwriting principles require borrowers to have a verified capacity and willingness to support the obligation and a well-supported valuation of the collateral. Loans are underwritten on either a delegated or non-delegated basis, but all loans pass through our eligibility rules engine to screen out those outside of our guidelines. We regularly monitor national and local market conditions, the performance of our products and the performance of our customers against our expectations for mix and profitability. We adjust our underwriting, pricing and risk selection strategies on a regular basis so that our products remain competitive and consistent with our risk and profitability objectives.

Quality Assurance

We have an independent quality assurance function that conducts pre- and post-closing underwriting reviews. We review statistically significant samples of loan files from individual customers and across our delegated and non-delegated underwriting channels to identify adverse trends and provide our underwriters and customers with timely feedback and training that fosters high quality loan production. Within our delegated channel, the frequency of our lender specific reviews is directly related to an account’s activity, that is, larger accounts will receive more frequent reviews. The results of these reviews also allow for adjustments to underwriting processes and credit policy. Finally, our quality assurance team conducts independent reviews on key operational processes and critically important vendor activities.

Portfolio Management

We regularly monitor the characteristics and performance of our overall mortgage insurance portfolio. We monitor concentrations across a range of metrics including lender, geography and policy year. Through stress testing, we evaluate the performance of the portfolio and identify risks to our strategic plan caused by its makeup in adverse economic scenarios. We also monitor performance against expected loss development from time of origination. Variations identified by product, performance, geography or otherwise inform adjustments to our guidelines and pricing strategies.

Business Continuity

We have a robust business continuity program to prepare for and manage through business interruptions. Maintenance and execution of our plan is led by a crisis management leader reporting to our Chief Risk Officer. We update our plan no less than annually to accommodate changes in business processes and third-party providers and test the plan regularly through tabletop exercises. We have used a decentralized team of underwriters and other key functional employees for many years and all employees are capable and equipped to work remotely so that we can continue providing service to our customers through prolonged absences from the office.

Underwriting

We establish and maintain underwriting guidelines based on our risk appetite. Our guidelines require borrowers to have a verified capacity and willingness to support their obligation and a well-supported valuation of the collateral. Our underwriting guidelines incorporate credit eligibility requirements that, among other things, limit our coverage to mortgages that meet our thresholds with respect to borrower FICO scores, maximum LTVs, documentation requirements and maximum Debt-to-Income (“DTI”) Ratios. All loans must pass through our eligibility rules engine to screen out those outside of our guidelines.

At present, our underwriting guidelines are largely consistent with those of the GSEs. Many of our customers use the GSEs’ automated loan underwriting systems, Desktop Underwriter and Loan Product Advisor, for making credit determinations. We generally accept the underwriting decisions and documentation requirements made by the GSEs’ underwriting systems, subject to our review as well as certain limitations and requirements.

11

Our policies are issued through one of two underwriting programs:

Non-Delegated Underwriting

For non-delegated underwriting, customers submit loan files to us, and we individually underwrite each application to determine whether we will insure the loan. We use our mortgage insurance underwriting system to perform our non-delegated underwriting evaluations. Our underwriting staff is dispersed throughout the United States, and we believe this allows us to make prompt, geographically based underwriting determinations across different time zones in a timely manner to best serve our diverse customer base. In addition to our employees, we use contract underwriters, as needed, to assist with underwriting capacity and drive efficiency.

Delegated Underwriting

We delegate to eligible lender customers the ability to underwrite mortgage insurance based on our delegated underwriting guidelines. To perform delegated underwriting, customers must be approved by our risk management team. Some customers prefer to assume underwriting responsibility because it is more efficient within their loan origination process, and they are comfortable attesting that the data they submit to us is true and correct when we make our insurance decision. We regularly perform quality assurance reviews on a statistically significant sample of delegated loans to assess compliance with our guidelines.

We also offer a post-closing underwriting review when requested by customers for both non-delegated and delegated loans. Upon satisfactory completion of this review, we agree to waive our right to rescind coverage under certain circumstances. For the years ended December 31, 2025 and 2024, approximately 73% and 71%, respectively, of our NIW by loan count went through our delegated underwriting services.

Pricing

Pricing is highly competitive in the mortgage insurance industry, with industry participants competing for market share, customer relationships and overall value. To appropriately align price and risk, dynamic pricing engines utilize granular pricing models based on a number of loan, borrower, lender and property risk attributes. Our risk-based pricing engine was developed to evaluate returns and volatility under both the PMIERs capital framework and our internal economic capital framework, which is sensitive to economic cycles and current housing market conditions. The model assesses the performance of new business under expected and stress scenarios on an individualized loan basis, which is used to determine pricing and inform our risk selection strategy that optimizes economic value by balancing return and volatility.

Our policy has been to set and charge premium rates commensurate with the underlying risk of each loan we insure. Our proprietary pricing platform, however, provides us with a more flexible, granular and analytical approach to selecting and pricing risk. Using our platform, we can quickly change price to modify our risk selection levels in response to changing economic conditions, new analytical insights or industry pricing trends.

Credit Risk Transfer

Our risk management framework and analytics inform our CRT strategy, which is designed to reduce the loss volatility of our in-force portfolio during stress scenarios by transferring risk from our balance sheet to highly rated counterparties or to investors through collateralized transactions. Our CRT program also provides capital relief under PMIERs and state insurance capital requirements. In normal market conditions, we believe our CRT program also enhances our return profile. Given the volatility protection and capital relief at attractive terms, CRT enables us to employ an “acquire, manage and distribute” strategy. We believe our CRT program is a material component of our strategy and helps to protect future business performance and stockholder capital under stress scenarios.

12

Our CRT program distributes risk to both highly rated counterparties through our traditional reinsurance program, as well as to insurance-linked note (“ILN”) investors via fully collateralized special purpose reinsurance vehicles. Our traditional reinsurance program utilizes excess-of-loss (“XOL”) and quota share insurance coverage.

Our XOL reinsurance transactions generally cover a subset of loans in a given book year where typically both the attachment and detachment points of the ceded risk tier are within the PMIERs capital requirements at inception, providing both loss volatility protection and PMIERs capital credit. Each reinsurance treaty has a term of ten years or more and provides a unilateral right to commute prior to the full term, subject to certain performance triggers. We select the type and structure of our CRT transactions based on a variety of factors including, but not limited to, capacity, cost, flexibility, sustainability and diversification. Under our quota share reinsurance agreements, the reinsurer receives a premium in exchange for covering an agreed-upon portion of incurred losses.

The Company’s traditional reinsurance coverage is provided by a panel of reinsurance partners each currently rated “A-” or better by Standard & Poor’s (“S&P”) or A.M. Best Company, Inc., or “A3” or better by Moody’s. These reinsurers are contractually required to collateralize a portion (typically 20 to 30%) of the reinsurance exposures consistent with PMIERs.

Delinquencies, Loss Management and Claims

The delinquency and claim cycle generally begins with our receipt of a delinquency notice on an insured loan from the related servicer. We consider a loan to be delinquent when it is two or more mortgage payments past due. The incidence of delinquency is affected by a variety of factors, including housing price appreciation or depreciation, unemployment, the level of borrower income, divorce, illness, interest rate levels, general borrower creditworthiness and macroeconomic conditions. See “1A. Risk Factors—Risks Relating to Our Business—A deterioration in economic conditions, a severe recession or a decline in home prices may adversely affect our loss experience.” Delinquencies that are not cured may result in a claim.

Our loss mitigation and claims area is led by seasoned personnel who are supported by default tracking and claims processing capabilities within our integrated platform. Our loss mitigation staff is also actively engaged with the GSEs and servicers regarding appropriate servicing and loss mitigation practices. We have granted loss mitigation delegation to the GSEs and servicers, whereby they perform certain loss mitigation efforts on our behalf. Moreover, the Consumer Financial Protection Bureau (“CFPB”) servicing rule obligates servicers to engage in early intervention and loss mitigation efforts with a borrower prior to foreclosure. These efforts have traditionally involved loan modifications intended to enable qualified borrowers to make restructured loan payments or efforts to sell the property, thereby potentially reducing claim amounts. Historically, the use of forbearance plans was limited to 12 months and primarily used for a natural disaster that impacted a region of the country. At the conclusion of the forbearance term, a borrower could either bring the loan current, defer any missed payments until the end of their loan, pay missed payments through a repayment plan or have one or more terms of the original note modified via a loan modification. In the years impacted by COVID 19, we experienced increased use of forbearance plans to assist borrowers. Given the relative recent success, the industry continues to use forbearance as a loss mitigation strategy.

Our goal is to keep borrowers in their homes. If a loan becomes delinquent, we work closely with customers, investors and servicers to attempt to cure the delinquency and allow the homeowner to retain ownership of their property.

Claims result from delinquencies that are not cured, or from losses on short sales, other third-party sales or deeds-in-lieu of foreclosure that we approve. Various factors affect the frequency and severity of claims, including LTV at the time of foreclosure, size and coverage percentage of a loan, property values, employment levels and interest rates. Any delays in foreclosure, including foreclosure moratoriums imposed by state and local governments and the GSEs, could cause our losses to increase as expenses

13

accrue for longer periods or if the value of foreclosed homes decline during such foreclosure delays. For loans insured on or after October 1, 2014, our mortgage insurance policies limit the number of months of unpaid interest and associated expenses that are included in the mortgage insurance claim amount to a maximum of 36 months.

Under the terms of our primary insurance master policy, customers are required to file claims within 60 days of the earliest of (i) the date they have acquired title to the underlying property (typically through foreclosure), (ii) the date of an approved short sale or other third-party sale of the underlying property or (iii) the date a request is made by us to file a claim.

Upon review and determination that a filed claim is valid, we generally have the following three settlement options:

•Percentage option—determined by multiplying the claim amount by the applicable coverage percentage, with the customer retaining title to the property. The claim amount generally consists of the unpaid loan principal as of the date of default, plus delinquent interest and certain expenses associated with the default;

•Third-party sale option—pay the amount of the claim required to make the customer whole, commonly referred to as the “actual loss amount,” following an approved sale; or

•Acquisition option—pay the full claim amount and acquire title to the property.

Claim activity is not evenly spread across the coverage period of loans we insure. The number of delinquencies may not correlate directly with the number of claims received because the rate at which delinquencies are cured is influenced by borrowers’ financial resources and circumstances, as well as regional economic differences. For those loans that fail to cure, whether delinquency leads to a claim principally depends upon the borrower’s equity at the time of delinquency and the borrower’s or the insured’s ability to sell the home for an amount sufficient to satisfy all amounts due under the mortgage loan.

When claim notices are received, we review loan and servicing files to determine the appropriateness of a claim amount. Failure to deliver required documentation or our review of such documentation may result in rescission, cancellation or claims denial. Our insurance policies provide that we can reduce or deny claims if the servicer does not materially comply with its obligations under our policies, including the requirement to pursue reasonable loss mitigation actions. We also periodically receive claim notices that request coverage for costs and expenses associated with items not covered under our policies, such as losses resulting from property damage to a covered home. We actively review claim notices in an effort to ensure we pay only for covered expenses. We deem a reduction in the claim amount paid relative to the amount requested in the claim notice to be a curtailment.

When reviewing loan and servicing files in connection with the delinquency or claims process, we may also decide to rescind coverage of the underlying mortgages or deny payment of claims. Our ability to rescind coverage is limited by the terms of our master policies. We may rescind coverage in situations where, among other things, (i) fraudulent misrepresentations were made or materially inaccurate information was provided regarding a borrower’s income, debts, intention to occupy a property or property value or (ii) a loan was originated in material violation of our underwriting guidelines.

We will consider an insured’s appeal of our decision and, if we agree with the appeal, we take the necessary steps to reinstate our insurance coverage and reactivate the loan certificate or otherwise address the issues raised in the appeal. If the parties are unable to agree on the outcome of the appeal, the insured may choose to pursue arbitration or litigation under the terms of the applicable master policy and challenge the results. Subject to applicable limitations in our policies and state law, legal challenges to our actions may be brought several years after we dispose of a claim.

14

From time to time, we enter into agreements with policyholders to accelerate claims and negotiate an agreed-upon payment amount for claims on an identified group of delinquent loans. In exchange for our accelerated claim payment, mortgage insurance is canceled, and we are discharged from any further liability on the identified loans.

Information Technology

We develop and invest in technology in order to drive operational excellence, promote a superior customer experience and support our overall business objectives. Our business heavily relies upon information technology and a number of critical aspects are highly automated. We accept insurance applications, issue approvals, process claims and reconcile premium remittance through electronic submission. In order to facilitate these processes, we have established direct connections to many industry leading origination and servicing systems so that our customers and servicers can select our mortgage insurance products and communicate with us directly from within their own technology platform. We also provide our customers secure access to our web-based portals to facilitate transactions and provide customers with access to their account information.

We are regularly upgrading and enhancing our systems and technology, with an eye towards expanding our capabilities, improving productivity and enhancing our customer experience, including:

•Policy administration, billing, delinquency and claims processes and systems;

•Enhancing the speed and efficiency of our pricing and auto-decisioning capabilities;

•Ensuring optimal integration capabilities to our customers’ loan origination and mortgage insurance ordering and rate quoting processes; and

•Artificial intelligence and machine learning in the areas of risk and portfolio management.

We have also implemented an overarching technology strategy that utilizes Cloud, Software as a Service, commercial software and in some cases proprietary technology to provide scalability, flexibility and an enhanced security posture. Technology costs are managed by the continued automation of key business processes, reducing our application portfolio and using contract employees to scale resource capacity as needed.

Ratings

Ratings with respect to the financial strength of operating subsidiaries are an important factor in establishing the competitive position of insurance companies. Ratings are important to maintaining public confidence in us and our ability to market our products. Rating organizations review the financial performance and condition of most insurers and provide opinions regarding financial strength, operating performance and ability to meet obligations to policyholders.

To review our current ratings, see “Item 7. Management Discussion and Analysis of Financial Condition and Results of Operations - Financial Strength Ratings.”

Investment Portfolio

The investment portfolios of our insurance subsidiaries are directed by the Enact Investment Committee, a management-level committee, with Genworth serving as the primary investment manager. Under the terms of our investment management agreement, the Company is charged an investment management fee by Genworth. See Note 11 to our audited consolidated financial statements for further information.

The investment portfolio of EHI is directed by a separate management-level EHI Investment Committee with a third-party investment manager. In addition, for certain asset classes, we utilize external asset management. In the future, we may choose to more broadly engage external asset managers. Our

15

senior management team, along with our board of directors, reviews investment performance and strategy on a periodic basis. As of December 31, 2025, the fair value of our investment portfolio was $6.1 billion of fixed maturity assets, of which 99% was rated as investment grade. We also had an additional $582 million of cash and cash equivalents as of December 31, 2025. The primary objectives of managing the investment portfolio are to preserve capital, generate investment income and maintain sufficient liquidity to cover our operating expenses and pay future insurance claims. Investment strategies are implemented emphasizing fixed income, low volatility, highly liquid assets to meet expected and unexpected financial obligations while enhancing risk adjusted, after-tax yields. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Investment Portfolio.”

Our board-approved investment policy utilizes defined investment guidelines such as, but not limited to, asset sector, single issuer concentration and credit ratings to maintain compliance with risk management limits, regulatory requirements and applicable laws. Asset class mix and risks are regularly evaluated in the context of current and future capital market conditions, liability profiles and return objectives. The investment portfolio is regularly stress tested to evaluate its ability to meet unexpected liquidity needs due to elevated liabilities. Our investment policies and strategies are subject to change depending on regulatory, economic and market conditions, as well as our prevailing operating objectives.

For more information regarding our investment portfolio, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations and Key Metrics—Investment Portfolio.”

Human Capital Management and Employees

We take a holistic approach to human capital management, including attracting and retaining talent with comprehensive benefits and compensation packages, providing professional development and learning opportunities, facilitating access to dedicated resources that foster an equitable and inclusive environment and encouraging a sincere commitment to community service and involvement. As of December 31, 2025, we had 419 full-time employees, all of whom work in the United States. Of our employees, 51% work in our Raleigh, North Carolina office and the remaining 49% are in the field, predominantly working in sales and underwriting. We supplement our workforce, as needed, with independent contractors. Our employees and contractors are all equipped to work on a remote basis. None of our employees are represented by a union or subject to a collective servicing agreement and management believes that our relationship with our employees is good.

Some of our key areas of focus include:

•Our compensation package, including salary, incentive bonus and long-term incentives, aligns employee and stockholder interests, as well as rewards our employees for serving all our current and future customers.

•In addition to a competitive compensation program, we offer our employees benefits such as life and health insurance, paid time off, paid parental leave, childcare subsidies, retirement savings plans, financial planning services, an Employee Assistance Program and a broad fitness reimbursement program to support physical and mental health. Our office building also houses an employee fitness center providing equipment, virtual classes, and massage therapy options on-site.

•We offer a multitude of professional development and career enrichment opportunities, including in the areas of leadership, professional skills, and industry-specific matters, as well as a mentor program and bespoke training for future senior leaders. We also offer tuition reimbursement benefits and student loan repayment options to aid career progression. We routinely assess talent, engage in deep succession planning at all levels of the organization and provide feedback to our employees through a formal annual performance review process.

16

•Our employee-led council focused on our employee population helps to build an inclusive culture through company-wide events and by educating our employees on the experiences and perspectives of others.

•We champion civic engagement through paid volunteer time for employees, event sponsorship programs, employee-directed charitable gifts with a 100% company match, the Enact Foundation, and through our commitment to environmental sustainability.

•We empower employees to share their unique perspectives by promoting initiatives that increase access to our Senior Leadership Team and encouraging open-door policies. We value the voice of our employees and use a best-in-class third party approach to gather employee feedback.

•We celebrate our talent by showcasing employee achievements and expertise in industry and local publications, at events and conferences, and through our online presence. Enact was recognized as an award winner by external organizations on four occasions throughout 2025.

Regulation

General

Our insurance operations are generally subject to extensive oversight and a wide variety of laws and regulations. State insurance laws and regulations govern most aspects of our insurance business and are enforced by the insurance departments of each jurisdiction in which our insurers are licensed, with the North Carolina Department of Insurance (“NCDOI”) being the lead regulator for our North Carolina domiciled insurers. Our insurance products and business also are affected by federal, state and local laws, including tax laws. Our Bermuda domiciled insurer, Enact Re, is subject to Bermuda law and is subject to regulation by the Bermuda Monetary Authority (“BMA”).

The primary purpose of the U.S. and Bermudian insurance laws and regulations regulating our insurance business is to protect our insureds. These laws and regulations are regularly re-examined by insurance regulators and any changes to these laws or new laws may be more restrictive or otherwise adversely affect our operations.

Insurance and other regulatory authorities (including state law enforcement agencies and attorneys general and the BMA) may make inquiries regarding compliance with insurance, securities and other laws and regulations, and we cooperate with such inquiries and take corrective action when warranted.

Insurance Company Regulation

Our insurance subsidiaries are licensed and regulated in all jurisdictions in which they conduct insurance business. The extent of this regulation varies, but state insurance laws and regulations generally grant both broad and specific regulatory powers to agencies or officials to examine the affairs of our insurance subsidiaries and to enforce statutes and administrative rules or exercise discretion affecting almost every aspect of their businesses. For example, state insurance laws and regulations typically govern the financial condition of insurers, including standards for solvency, types and concentrations of permissible investments, establishment and maintenance of reserves, credit for reinsurance, requirements for capital adequacy, and the business conduct of insurers, including marketing, sales practices and claims handling. State insurance laws and regulations also usually require the licensing of insurers and agents, and the approval of policy forms and rates. In addition, states may require actuarial justification of rates on the basis of the insurer’s loss experience, expenses and future projections. Enact Re is subject to a similar Bermudian regulatory regime.

Mortgage guaranty insurance premium rates and policy forms are subject to regulation in every jurisdiction in which our insurance subsidiaries are licensed to transact business in order to protect policyholders against the adverse effects of excessive, inadequate or unfairly discriminatory rates. In most

17

jurisdictions, premium rates and policy forms must be filed prior to their use. In some states, such rates and forms must also be approved prior to use. Changes in premium rates are often subject to justification, generally on the basis of loss experience, expenses and future trend analysis. In addition, jurisdictions may consider general default experience in the mortgage insurance industry in assessing the premium rates charged by mortgage guaranty insurers. Applicable state insurance laws and regulations, along with certain additional state insurance laws and regulations specific to mortgage guaranty insurers, are described below.

Insurance Holding Company Regulation

Certain of our insurance subsidiaries are subject to the Insurance Holding Company Act in North Carolina and are required to furnish various types of information concerning the operations of, and the interrelationships and transactions among, companies within our holding company system that may affect the operations, management or financial condition of the insurers within such holding company system. Under state insurance laws and regulations, our insurance subsidiaries must file reports, including detailed annual and quarterly financial statements, with the insurance regulator in North Carolina and the National Association of Insurance Commissioners (“NAIC”), and our operations and accounts are subject to periodic or target examination by any insurance regulator of a jurisdiction in which we conduct business. Mortgage guaranty insurers generally are limited by state insurance laws and regulations to directly writing only mortgage guaranty insurance business to the exclusion of other types of insurance.

State insurance laws and regulations also regulate transactions between insurers and their affiliates, sometimes mandating prior notice to the regulator and/or regulatory approval. Generally, state insurance laws and regulations require that all transactions between an insurer and an affiliate be fair and reasonable, and that the insurer’s statutory surplus following such transaction be reasonable in relation to its outstanding liabilities and adequate for its financial needs. Certain transactions may not be entered into unless the applicable regulator is given 30 days’ prior notification and does not disapprove the transaction during such 30-day period.

State insurance laws and regulations also require that an insurance holding company system’s ultimate controlling person submit annually to its lead state insurance regulator an “enterprise risk report” that identifies activities, circumstances or events involving one or more affiliates of an insurer that, if not remedied properly, are likely to have a material adverse effect upon the financial condition or liquidity of the insurer or its insurance holding company system as a whole. Finally, most jurisdictions have adopted insurance laws or regulations setting forth detailed requirements for cost sharing and management agreements between an insurer and its affiliates.

State insurance laws and regulations require that a person obtain the approval of the insurance commissioner of an insurer’s domiciliary jurisdiction prior to acquiring control of such insurer. Control of an insurer is generally presumed to exist if any person, directly or indirectly, owns, controls, holds with the power to vote, or holds proxies representing, 10% or more of the voting securities of the insurer or any parent entity; although such presumption may be rebutted. In considering an application to acquire control of an insurer, the insurance commissioner generally considers factors such as the experience, competence and financial strength of the applicant, the integrity of the applicant’s board of directors and executive officers, the acquirer’s plans for the management and operation of the insurer, and any anti-competitive results that may arise from the acquisition. Most jurisdictions also require a person seeking to acquire control of an insurer licensed but not domiciled in that jurisdiction to make a filing prior to completing an acquisition if the acquirer and its affiliates and the target insurer and its affiliates have specified market shares in the same lines of insurance in that jurisdiction. These provisions may not require acquisition approval but can lead to imposition of conditions on an acquisition that could delay or prevent its consummation. In certain situations, state insurance laws and regulations also require that a controlling person of an insurer submit prior notice to the insurer’s domiciliary insurance regulator of a divestiture of control. Similarly, with respect to our contract underwriting entity, Enact Financial Services, Inc., prior approval from state banking commissioners is required in some jurisdictions prior to acquiring

18

control of our contract underwriting entity, which is licensed or has an approved license exemption in most states.

Our U.S. domiciled insurance subsidiaries’ payment of dividends or other distributions to our holding company is regulated by the state insurance laws and regulations of their respective domiciliary states. Our insurance subsidiaries must deliver notice to the Commissioner of any dividend or distribution within 5 business days after declaration of the dividend or distribution, and at least 30 days before payment thereof. Any distribution, regardless of amount, requires that same 30-day notice to the Commissioner, but also requires the Commissioner’s affirmative approval before being paid.

Under the insurance laws of the State of North Carolina, an “extraordinary” dividend or distribution is defined as a dividend or distribution that, together with other dividends and distributions made within the preceding 12 months, exceeds the greater of: (i) 10% of the insurer’s statutory surplus as of the immediately prior year end; or (ii) the statutory net income (loss) during the prior calendar year.

In addition, insurance regulators may prohibit the payment of ordinary dividends and distributions or other payments by our insurers (such as a payment under a tax sharing agreement, for employment or other services) if they determine that such payment could be adverse to our policyholders or would not be fair and reasonable to the insurer.

Enact Re’s payment of dividends and distributions is subject to Bermudian law and oversight by the BMA.

National Association of Insurance Commissioners

The NAIC’s mandate is to benefit state insurance regulatory authorities and consumers by promulgating model insurance laws and regulations for adoption by the states. The NAIC also provides standardized insurance industry accounting and reporting guidance through the NAIC Accounting Manual. However, model insurance laws and regulations are only effective when adopted by the states, and NAIC Statutory Accounting Principles (“SAP”) may be superseded by individual state laws, regulations and permitted practices. Changes to the NAIC Accounting Manual or modifications by the various state insurance departments may affect the statutory capital and surplus of our insurance subsidiaries.

The NAIC adopted the Risk Management and Own Risk and Solvency Assessment Model Act (the “ORSA Model Act”). The ORSA Model Act requires an insurance holding company to regularly, and no less than annually, assess the adequacy of our insurance subsidiaries’ risk management framework and current and estimated projected future solvency position; internally document the process and results of the assessment; and provide a confidential high-level report annually to the lead state commissioner. We comply by participating in Genworth’s ORSA reporting.

Examinations

State insurance laws and regulations govern the marketplace for U.S. domiciled insurers, affecting the form and content of disclosure to insureds, advertising, sales and underwriting practices and complaint and claims handling, and these provisions are generally enforced through periodic or target market conduct examinations. State insurance departments may conduct periodic or target detailed examinations of the books, records, accounts and business practices of insurers licensed in their states. These examinations are sometimes conducted in cooperation with insurance departments of multiple other states or jurisdictions representing each of the NAIC zones, under guidelines promulgated by the NAIC.

Accounting Principles

State insurance regulators developed SAP as a basis of accounting used to monitor and regulate the solvency of insurers. Since insurance regulators are primarily concerned with ensuring an insurer’s ability

19

to pay its current and future obligations to policyholders, statutory accounting conservatively values the assets and liabilities of insurers, generally in accordance with standards specified by such insurer’s domiciliary jurisdiction. Uniform statutory accounting practices are established by the NAIC and are generally adopted by regulators in the various state jurisdictions. Due to differences in methodology between SAP and United States generally accepted accounting principles (“U.S. GAAP”), the values for assets, liabilities and equity reflected in financial statements prepared in accordance with U.S. GAAP are often materially different from those reflected in financial statements prepared under SAP. Enact Re abides by Bermudian statutory accounting.

Market Conduct

State insurance laws and regulations govern the marketplace activities of insurers, affecting the form and content of disclosure to consumers, advertising, product replacement, sales and underwriting practices and complaint and claims handling, and these provisions are generally enforced through periodic market conduct examinations. Our insurance subsidiaries are not currently undergoing market conduct reviews in any states or other jurisdictions.

Investments

State insurance laws and regulations require diversification of our insurance subsidiaries’ investment portfolio and limit the proportion of, or in some cases totally prohibit, investments our insurance subsidiaries may hold in different asset categories. Assets invested contrary to such regulatory limitations must be treated as non-admitted assets for assessing an insurer’s solvency unless a waiver is given by the insurer’s domestic insurance regulator, and, in some instances, regulations require divestiture of such non-complying investments. We believe our insurance subsidiaries’ investments are in compliance with these state insurance laws and regulations or are subject to any applicable waivers. Enact Re’s investments are governed by, and in compliance with, Bermudian law.

Capital and Surplus Requirements

Insurance regulators have discretionary authority, in connection with the licensing of our insurance subsidiaries, to limit or restrict insurers from issuing new policies, or to take other actions, if, in the regulators’ judgment, the insurer is not maintaining a sufficient amount of surplus or reserves, or is in a hazardous financial condition. We seek to maintain new business and capital management strategies to support meeting related regulatory requirements. Enact Re is subject to Bermuda’s capital regime.

Mortgage Guaranty Insurance Capital and Surplus Requirements. Mortgage guaranty insurers are not subject to the NAIC’s risk-based capital (“RBC”) requirements, but certain states impose other forms of capital requirements on mortgage guaranty insurers, requiring maintenance of a risk-to-capital (“RTC”) ratio not to exceed 25:1. Statutory capital for purposes of the 25:1 1 RTC ratio limit is defined as surplus as regards policyholders plus contingency reserves, less ceded reinsurance.

In August 2023, the NAIC adopted amendments to the Mortgage Guaranty Insurance Model Act (the “MGI Model”) and is in the process of making conforming revisions to Statement of Statutory Accounting Principles No. 58—Mortgage Guaranty Insurance. The revisions to the MGI Model are extensive, including with respect to the risk concentration limits, capital and reserve requirements, reinsurance, underwriting practices and quality assurance. At this time, we cannot predict (i) which states, if any, may adopt the MGI Model; (ii) the effect changes in the MGI Model may have on the mortgage guaranty insurance market generally, or on our business specifically; (iii) the additional costs associated with compliance with any such changes; or (iv) any changes to our operations that may be necessary to comply, any of which could have a material adverse effect on our business, results of operations and financial condition. We also cannot predict whether other regulatory initiatives will be adopted and what impact, if any, such initiatives, if adopted as laws, may have on our business, results of operations and financial condition.

20

Group Capital Requirements. The NAIC has developed and implemented a group capital calculation (“GCC”) tool using an RBC aggregation methodology for all entities within the insurance holding company system, including non-U.S. entities. The GCC provides regulators with an additional tool for conducting group-wide supervision and enhances transparency into how capital is allocated. We submit the required GCC filing annually to Virginia, our insurance holding company group’s lead state. It is unclear how the development of group capital measures by the NAIC will interact with existing capital requirements for U.S. insurance companies.

Reserves

State insurance laws and regulations require our U.S. mortgage insurance subsidiaries to establish a special statutory contingency reserve reflected in their statutory financial statements to provide for payable claims and other expenses and purposes in the event of significant economic declines. Annual additions to the statutory contingency reserve must be at least 50% of net earned premiums as defined by state insurance laws and regulations. These contingency reserves generally are held until the earlier of (i) 10 years after which such amounts can be released into surplus or (ii) when loss ratios exceed 35% in which case, the amount above 35% can be released under certain circumstances, although regulators have granted discretionary releases from time to time. However, approval by the NCDOI is required for contingency reserve releases when loss ratios exceed 35%. The establishment of the statutory contingency reserve is funded by premiums that would otherwise generate net earnings that would be reflected in policyholder surplus. This deferral of premiums into the contingency reserve limits our mortgage insurance subsidiaries’ ability to pay dividends to stockholders until those contingency reserves are released back into surplus. Our mortgage insurance subsidiaries’ statutory contingency reserve was approximately $4,513 million and $4,336 million as of December 31, 2025 and 2024, respectively.

Dodd-Frank Act

Although the federal government generally does not directly regulate the insurance business, federal initiatives often have an impact on our business in a variety of ways. From time to time, federal measures are proposed that may significantly affect the insurance business. These areas include financial services regulation, securities regulation, derivatives regulation, money laundering, privacy regulation and taxation. In addition, various forms of direct federal regulation of insurance have been proposed in recent years.

The Dodd-Frank Act made extensive changes to the laws regulating financial services firms and required various federal agencies to adopt a broad range of new implementing rules and regulations.

The Dodd-Frank Act prohibits a creditor from making a residential mortgage loan unless the creditor makes a reasonable and good faith determination that, at the time the loan is consummated, the consumer has a reasonable ability to repay the loan. In addition, the Dodd-Frank Act created the CFPB, which regulates certain aspects of the offering and provision of consumer financial products or services but not the business of insurance. Certain rules and regulations established by the CFPB require mortgage lenders to demonstrate that they have effectively considered the consumer’s ability to repay a mortgage loan, establish when a mortgage may be classified as a Qualified Mortgage (“QM”) and determine when a lender is eligible for a safe harbor as a presumption that the lender has complied with the ability-to-repay requirements.

Agency Qualification Requirements

As the largest purchasers of conventional mortgage loans, and therefore, the main beneficiaries of private mortgage insurance, the GSEs impose eligibility requirements that private mortgage insurers must satisfy in order to be approved to insure loans purchased by the GSEs. Initially effective December 31, 2015, each GSE adopted the original PMIERs, which set forth operational and financial requirements that mortgage insurers must meet in order to remain eligible. PMIERs, which has had multiple subsequent updates, aims to ensure that approved insurers possess the financial and operational capacity to serve as strong counterparties to the GSEs throughout various market conditions. PMIERs is comprehensive, covering virtually all aspects of the business and operations of a private mortgage insurer of GSE loans,

21

including internal risk management and quality controls, underwriting, claim processing and loss mitigation, among others. In addition, PMIERs require private mortgage insurers to obtain the prior consent of the GSEs before taking certain actions, which may include entering into various intercompany agreements and commuting or reinsuring risk, among others. As of December 31, 2025, we met the PMIERs financial and operational requirements and currently hold capital in excess of the financial requirements.

PMIERs includes financial requirements for mortgage insurers under which a mortgage insurer’s “Available Assets” (generally only the most liquid assets of an insurer) must meet or exceed “Minimum Required Assets” (which are based on an insurer’s RIF and are calculated from tables of factors with several risk dimensions and are subject to a floor amount) and otherwise generally establish when a mortgage insurer is qualified to issue coverage that will be acceptable to the respective GSE for acquisition of high LTV mortgages. The GSEs may amend or waive PMIERs at their discretion, impose additional conditions or restrictions on us and also have broad discretion to interpret PMIERs, which could impact the calculation of our “Available Assets” and/or “Minimum Required Assets.”

The operational PMIERs requirements include standards that govern the relationship between the GSEs and approved insurers and are designed to ensure that approved insurers operate under uniform guidelines, such as claim processing timelines. They include quality control requirements that are designed to ensure that approved insurers have a strong internal risk management infrastructure and senior management oversight.

Under PMIERs, we are subject to these operational and financial requirements. Each approved mortgage insurer is required to provide the GSEs with an annual certification and a quarterly report as to its compliance with PMIERs.

In their respective letters approving credit for reinsurance against PMIERs financial requirements, the GSEs require our mortgage insurance subsidiary not to exceed a maximum statutory RTC ratio of 18:1 or they reserve the right to reevaluate the amount of PMIERs credit for reinsurance and other CRT transactions available under PMIERs indicated in their approval letters. Freddie Mac has also imposed additional requirements on our option to commute these reinsurance agreements. Both GSEs reserved the right to periodically review the reinsurance transactions for treatment under PMIERs.

As of December 31, 2025, we had estimated available assets of $5,015 million against $3,096 million net required assets under PMIERs compared to available assets of $5,095 million against $3,043 million net required assets as of December 31, 2024. The sufficiency ratio as of December 31, 2025, was 162% or $1,919 million above the PMIERs requirements, compared to 167% or $2,052 million above the PMIERs requirements as of December 31, 2024.

In addition, our PMIERs required assets as of December 31, 2024, benefited from the application of a 0.30 multiplier applied to the risk-based required asset amount factor for certain non-performing loans. Per guidance released by the GSEs, use of the multiplier was discontinued effective March 31, 2025.

On August 21, 2024, the GSEs and the FHFA released updated PMIERs requirements phasing in a revision to the available assets standards between March 31, 2025 and September 30, 2026. The updated standards differentiate between bonds based on credit quality and liquidity. The updates also established limits for assets backed by residential mortgages or commercial real estate to mitigate the impact if such assets lose value during periods of housing stress. We expect to hold capital sufficiency well in excess of these requirements and do not expect the impact of these updates to be material to our sufficiency. The ultimate impact of the PMIERs changes will be influenced by investment portfolio maturities, dispositions, reinvestments, and overall business and economic performance through the phase-in dates.

22

Other Federal Regulation

We and other private mortgage insurers are impacted by federal regulation of residential mortgage transactions with respect to mortgage originators and lenders, purchasers of mortgage loans such as Fannie Mae and Freddie Mac and governmental insurers such as the FHA and the VA. Mortgage origination and servicing transactions are subject to compliance with various state and federal laws, including but not limited to the Real Estate Settlement Procedures Act of 1974 (“RESPA”), HOPA, Fair Credit Reporting Act (“FCRA”), the Fair Housing Act, the Truth In Lending Act, the Gramm-Leach-Bliley Act of 1999 (the “GLB Act”) and the Dodd-Frank Act. Among other things, these laws and their implementing regulations prohibit payments for referrals of settlement service business, require fairness and non-discrimination in granting or facilitating the granting of insurance, govern the circumstances under which companies may obtain and use consumer credit information and provide for other consumer protections. Additionally, changes in federal housing legislation and other laws and regulations that affect the demand for private mortgage insurance may have a material effect on private mortgage insurers. For example, in December 2020, the Federal Housing Finance Agency (“FHFA”) promulgated the Enterprise Capital Framework that imposes a new capital framework on the GSEs, including risk-based and leverage capital requirements and buffers in excess of regulatory minimums that can be drawn down in periods of financial stress. This rule is part of the process to potentially end the conservatorships of the GSEs. The final rule could cause the GSEs to increase their guarantee pricing in order to meet the new capital requirements.

Federal Laws

RESPA applies to most residential mortgages insured by private mortgage insurers. Mortgage insurance is considered a “settlement service” for purposes of loans subject to RESPA. Subject to limited exceptions, RESPA precludes us from providing services to mortgage lenders or other settlement service providers free of charge, charging fees for services that are lower than their reasonable or fair market value and paying fees for services that others provide that are higher than their reasonable or fair market value. In addition, RESPA prohibits persons from giving or accepting any portion or percentage of a charge for a real estate settlement service, other than for services actually performed. Although many states prohibit mortgage insurers from giving rebates, RESPA has been interpreted to cover many non-fee services as well. Mortgage insurers and their customers are subject to the potential sanctions of this law, which may be enforced by the CFPB, state insurance departments, state attorneys general and other enforcement authorities.

HOPA provides for the automatic termination, or cancellation upon a borrower’s request, of the borrower’s obligation to pay for private mortgage insurance upon satisfaction of certain conditions. HOPA applies to owner-occupied residential mortgage loans regardless of lien priority and to borrower-paid mortgage insurance closed after July 29, 1999. HOPA requires lenders to automatically terminate a borrower’s obligation to pay for mortgage insurance coverage once the LTV ratio reaches 78% of the original value. A borrower generally may also request cancellation of mortgage insurance from their lender once the actual payments reduce the loan balance to 80% of the home’s original value. For borrower-initiated cancellation of mortgage insurance, the borrower must have a “good payment history” as defined by HOPA.

FCRA imposes restrictions on the permissible use of credit report information and requires mortgage insurance companies to provide “adverse action” notices to consumers in the event an application for mortgage insurance is declined or offered at less than the best available rate for the loan program applied for due to information contained in a consumer’s credit report.

The Fair Housing Act generally prohibits discrimination in the terms, conditions or privileges in residential real estate-related transactions on the basis of race, color, religion, sex, familial status or national origin. Numerous courts have held that the Fair Housing Act prohibits discriminatory insurance practices. In addition, both the Department of Justice (the “DOJ”) and the CFPB have pursued claims under the Fair Housing Act on a disparate impact theory as well.

23

Mortgage Servicing Rules

The CFPB Servicing Rule established servicer requirements for handling loans that are in default, handling escrow accounts, responding to borrower assertions of error and loss mitigation in the event that a borrower defaults. A provision of the required loss mitigation procedures prohibits a loan holder or servicers from commencing foreclosure until 120 days after the borrower’s delinquency. Since 2014, the CFPB has clarified those rules through subsequent rule makings and provided guidance on how servicers must apply them in certain circumstances.

Regulation of Mortgage Origination

Private mortgage insurers are also indirectly impacted by federal laws and regulations affecting mortgage originators and lenders, purchasers of mortgage loans and governmental insurers. Among the most significant of these laws and regulations are the Dodd-Frank Act QM and the ability-to-repay (“ATR”) requirement and the qualified residential mortgage (“QRM”) securitization risk retention provisions.

ATR and QM Rules

In addition to the QM rules discussed above, the Dodd-Frank Act separately granted statutory authority to the United States Department of Housing and Urban Development (“HUD”) (for FHA-insured loans), the VA (for VA-guaranteed loans), the United States Department of Agriculture (“USDA”) and Rural Housing Service (“RHS”) to develop their own definitions of a QM in consultation with the CFPB. In December 2013, HUD adopted a separate definition of a QM for loans insured by the FHA. HUD’s QM definition is less restrictive than the CFPB QM Rule in certain respects. To the extent that other government agencies guaranteeing residential mortgage loans may adopt definitions of a QM that are more favorable to lenders and mortgage holders than the CFPB QM Rule, our mortgage insurance business could also be negatively impacted.

The Dodd-Frank Act requires an originator or issuer to retain a specified percentage of the credit risk exposure on securitized mortgages that do not meet the definition of a QRM. As required by the Dodd-Frank Act, in 2015 the Federal Banking Agencies, the FHFA, the U.S. Securities and Exchange Commission (“SEC”) and HUD adopted a joint final rule implementing the QRM rules that aligns the definition of a QRM with that of a QM. In December 2019, the Federal Banking Agencies initiated a review of certain provisions of the risk retention rule, including the QRM definition. Among other things, the review allows the Federal Banking Agencies to consider the QRM definition in light of any changes to the QM definition under the QM Rule adopted by the CFPB, which would include the final rule promulgated by the CFPB on December 29, 2020. If the QRM definition is changed in a manner that is unfavorable to us, such as to require a large down payment for a loan to qualify as a QRM, without giving consideration to mortgage insurance in computing LTV ratios, the attractiveness of originating and securitizing loans with lower down payments may be reduced, which may adversely affect the future demand for mortgage insurance.

Basel III

Since 1988, the Basel Committee has worked to develop international benchmarks for assessing banks’ capital adequacy requirements. In 2005, the Basel Committee issued Basel II, which, among other things, sets forth capital treatment of mortgage insurance purchased and held on balance sheet by banks in respect of their origination and securitization activities (including in bank regulation, the standards for a prudentially underwritten mortgage, with 50% risk weighting for high loan-to-value mortgages covered with mortgage insurance). Following the financial crisis of 2008, the Basel Committee issued Basel III that established RBC and leverage capital requirements for most United States banking organizations (although banking organizations with less than $10 billion in total assets may now choose to comply with

24

an alternative community bank leverage ratio framework established by the Federal Banking Agencies in 2019).

In 2013, the U.S. federal banking regulators confirmed the role of mortgage insurance as a component of prudential bank regulation for high loan to value mortgages. More recently, in July of 2023, the Federal Reserve, the Federal Deposit Insurance Corporation and the Office of the Comptroller of the Currency proposed for comment the Basel III Endgame rule. As originally proposed, the rule would have eliminated the 50% risk‑based capital benefit for high‑LTV portfolio mortgages with private mortgage insurance for banking organizations with $100 billion or more in total assets, which, if adopted, could reduce demand for mortgage insurance. Since the Basel III Endgame proposal was issued, U.S. banking regulators have since withdrawn that proposal and indicated that the standard will be re-proposed with significant revisions. As a result, the timing, substance, and ultimate impact of the Basel III Endgame on financial institutions, and the mortgage insurance market, remains uncertain.

Privacy of Consumer Information and Cybersecurity

Federal and state laws and regulations require financial institutions, including insurance companies, to protect the security and confidentiality of consumer financial information and to notify consumers about policies and practices relating to the collection, use, disclosure, security, and confidentiality of their personally identifiable information. Additionally, there are federal and state obligations to notify regulators and consumers in the event of certain data breaches affecting personal information.

Federal and state lawmakers and regulatory bodies may consider additional or more detailed regulations regarding these subjects and the privacy and security of nonpublic personal information, confidential business information, information security systems, and vendors and other third parties that may have access to sensitive data or systems. Furthermore, the issues surrounding data security and the safeguarding of consumers’ protected information are under increasing regulatory scrutiny by state and federal regulators, particularly in light of the number and severity of recent United States companies’ data breaches. Several states have enacted privacy and information security requirements and insurance laws that require certain regulated entities to implement and maintain comprehensive information security programs to safeguard the personal information of insureds and enrollees.

The GLB Act and the FCRA impose privacy and information security requirements on financial institutions, including obligations to protect and safeguard consumers’ nonpublic personal information and creditworthiness information, respectively, and limitations on the use and sharing of such information. The GLB Act requires administrative, technical, and physical safeguards to ensure the security, confidentiality, integrity, and the proper disposal of nonpublic personal information, and the FCRA imposes similar information security requirements regarding the protection of creditworthiness information. The FCRA limits an entity’s ability to disclose creditworthiness information to affiliates and nonaffiliates unless certain notice requirements are met and the consumer does not elect to prevent or “opt out” of the disclosure, and it limits an entity’s ability to use creditworthiness information except for certain authorized purposes. The GLB Act limits a financial institution’s disclosure of nonpublic personal information to unaffiliated third parties unless certain notice requirements are met, and the consumer does not elect to prevent or “opt out” of the disclosure. The GLB Act requires that financial institutions provide privacy notices to their customers. With respect to our business, the GLB Act is enforced by the CFPB and state insurance regulators, and the FCRA is enforced by the CFPB. CFPB regulations implement certain sections of the GLB Act regarding privacy and information security, and state insurance regulations also implement certain sections of the GLB Act regarding privacy and information security, including requirements to notify individuals regarding certain data security incidents that affect their nonpublic personal information. Certain states have implemented certain requirements of the GLB Act, including North Carolina through the Consumer and Customer Information Privacy Act.

Many states have enacted privacy and data security laws that impose compliance obligations beyond those imposed by the GLB Act, including obligations to protect sensitive personal information. All fifty states also require entities to provide notification to affected state residents and, in certain instances,

25

state regulators, such as state attorneys general or state insurance commissions, in the event of certain security breaches affecting personal information, though some of these laws include exemptions for entities regulated by the GLB Act.

The California Consumer Privacy Act of 2018 (the “CCPA”) was amended significantly by the California Privacy Rights Act of 2020 (“CPRA”) and again amended in 2025 by the California Privacy Protection Agency (CalPrivacy). The CCPA and its amendments grant California residents the right to know what information a business has collected about them and the sourcing and sharing of that information, as well as the right to access and correct their personal information, and (subject to certain exemptions) the right to have a business delete their personal information. The CPRA created the California Privacy Protection Agency to enforce the CCPA and to promulgate regulations thereunder, imposed additional obligations regarding the privacy notice and service provider contracts, created new requirements around the protection of sensitive personal information and eliminated certain exemptions for personal information collected in employment or business-to-business contexts. Failure to comply with the CCPA risks regulatory fines, and the law grants a private right of action for any unauthorized disclosure of certain personal information not subject to an exemption as a result of failure to maintain reasonable security procedures and practices.

Many states have enacted comprehensive data privacy laws in the past few years. These laws generally impose similar requirements as the CCPA but most do not apply to employee or contractor data or business-to-business information. Each of these laws has either entity-wide or data-specific exemptions for financial institutions subject to the GLB Act. Adapting our data privacy practices to forthcoming applicable laws and regulations may increase our compliance costs and increase the risk of noncompliance.

Cybersecurity continues to be an area of significant and increasing focus of legislatures and regulators. The New York Department of Financial Services (“NYDFS”) amended its cybersecurity regulation which, along with subsequent guidance, requires all banks, insurance companies, and other financial services institutions and licensees regulated by the NYDFS, including several of our subsidiaries, to establish a cybersecurity program. The NYDFS cybersecurity regulation includes specific technical safeguards as well as requirements regarding governance, incident planning, training, encryption of nonpublic information, data management, system testing and regulator notification in the event of certain cybersecurity events. The amendments expand requirements for notification to the NYDFS of cybersecurity events and expand technical requirements around system penetration testing, vulnerability assessments, risk assessments and audits. The amendments also add new requirements related to cybersecurity plans and expand cybersecurity governance requirements, among other things. We are required to file an annual certification of compliance with the NYDFS regarding our cybersecurity program.

In addition, the NAIC’s Insurance Data Security Model Law establishes model standards for states to adopt regarding data security and notification of data breaches applicable to insurance licensees in states adopting such law, with provisions that are generally consistent with the NYDFS cybersecurity regulation discussed above. As with all NAIC model laws, this Insurance Data Security Model Law must be adopted by a state before becoming law in such state. A version of the Insurance Data Security Model Law has been adopted by over twenty states. North Carolina has not adopted a version of the Insurance Data Security Model Law. We anticipate that more states will begin adopting the Insurance Data Security Model Law, sometimes with state-specific modifications, in the near term, although it is not yet an accreditation standard. The NAIC has also adopted a guidance document that sets forth twelve principles for effective insurance regulation of cybersecurity risks based on similar regulatory guidance adopted by the Securities Industry and Financial Markets Association and the “Roadmap for Cybersecurity Consumer Protections,” which describes the protections to which the NAIC believes consumers should be entitled from their insurance companies, agents and other businesses concerning the collection and maintenance of consumers’ personal information, as well as what consumers should expect when such information has been involved in a data breach. We expect cybersecurity risk management, prioritization and reporting to

26

continue to be an area of significant regulatory focus by such regulatory bodies and self-regulatory organizations.

As noted above, state governments, Congress, and federal and state agencies may consider and enact additional legislation or promulgate regulations governing privacy, cybersecurity, and data breach reporting requirements. We cannot predict whether such legislation will be enacted, or what impact, if any, such legislation may have on our business practices, results of operations or financial condition.
