PART I

Assurant, Inc. was incorporated as a Delaware corporation in 2004.

We are a premier global protection company that partners with the world’s leading brands to safeguard and service connected devices, homes and automobiles. We leverage data-driven technology solutions to provide exceptional customer experiences. We operate in North America, Latin America, Europe and Asia Pacific through two operating segments: Global Lifestyle and Global Housing. Through our Global Lifestyle segment, we provide mobile device solutions, extended service contracts and related services for consumer electronics and appliances, and credit and other insurance products (referred to as “Connected Living”); and vehicle protection services, commercial equipment protection and other related services (referred to as “Global Automotive”). Through our Global Housing segment, we provide lender-placed homeowners, manufactured housing and flood insurance, as well as voluntary manufactured housing, condominium and homeowners insurance (referred to as “Homeowners”); and renters insurance and other products (referred to as “Renters and Other”).

Our Competitive Strengths

Our financial strength and capabilities across our businesses create competitive advantages that we believe allow us to support our clients, deliver a superior experience for their customers and drive sustainable profitable growth over the long term.

Our financial strength and business model. We believe we have a strong balance sheet and operating cash flows. As of December 31, 2025, we had $36.29 billion in total assets and our debt to total capital was 27.3%. Our business model in our Global Lifestyle and Global Housing segments focuses on business-to-business-to-consumer (B2B2C) distribution, partnered with some of the world’s leading brands. Our business model creates earnings and capital diversification, and generates significant operating cash flows, which provide us with the flexibility to make investments to strengthen our strategic capabilities and enhance our partnerships with our clients.

Insights and capabilities enable innovation and solutions to meet evolving consumer needs. We have deep partnerships with and an understanding of our clients and the consumer markets they serve. We seek to leverage consumer insights, together with extensive capabilities, to identify and anticipate the needs of our clients and the consumers they serve. We leverage those insights to invest in emerging technologies and operations, including digital capabilities supported by artificial intelligence (“AI”), to introduce innovative products and services and continuously adapt those offerings to the changing needs of consumers. Investments and innovation enable services that complement our protection and specialty insurance products, creating customized solutions for clients and customers.

Value chain and technology integration and customer experience. We own or manage multiple pieces of the value chain, which enables us to create products and service offerings based on client and consumer needs and provide a seamless customer experience. Offering end-to-end solutions allows us to provide additional value for consumers and adapt more quickly and efficiently to their needs. Visibility across the value chain and integrating our technology with clients helps us further improve the customer experience and our offerings. Our ability to introduce value-added services and capabilities across the value chain, integrate our technology and provide a superior customer experience allows us to strengthen our partnerships and our competitive position.

Our Strategy for Profitable Growth

As we focus on executing our strategy, we believe we are positioned for continued long-term profitable growth by:

Growing our portfolio of market-leading businesses. Our businesses represent a group of leading, protection and service-oriented offerings focused on compelling growth opportunities in specialized markets. We intend to grow our businesses by strengthening our partnerships with major clients and prospects globally, through expanded offerings and attachment with clients and by winning new clients, and by entering into attractive adjacent markets (such as home warranty), while continuing to invest in talent, capabilities and technology to enable us to deliver a superior customer experience.

Providing integrated offerings to deliver additional value for a superior customer experience. We provide customized solutions supported by integrated technology platforms to create a superior customer experience. As we continue to evolve our product and service capabilities and respond to client and consumer needs, we expect ongoing innovation of our integrated offerings, leveraging data-driven insights, technology, robotics and AI to deliver additional value for our clients and their customers.

Deploying our capital strategically. Our strong financial position provides us with flexibility to strategically deploy our capital. We generally deploy capital to support business growth by funding investments and through acquisitions, to pay dividends and to repurchase shares. We target new businesses and capabilities, organically and through acquisitions, that complement or accelerate our strategy, including in adjacent markets. Our approach to acquisitions and other growth opportunities reflects our strategic and disciplined approach to capital management.

Investing in talent and technology. Our employees play a critical role in contributing to our success and supporting our business strategy. We believe in fostering an inclusive culture to drive sustainable profitable growth over the long term. We are focused on strategically attracting, developing, retaining and motivating our talent, as we prioritize programs and initiatives aimed at investing in their growth, skills and wellbeing. We continue to invest in technology, including digital, robotics and AI, and seek to integrate technology platforms with our clients, to create superior customer experiences.

2025 Highlights

In 2025, we delivered another year of profitable growth and reinforced our solid foundation for the future by prioritizing disciplined investments in innovation across our diversified Global Lifestyle and Global Housing businesses.

In Global Lifestyle, growth was driven by new client programs and the continued expansion of our partnerships and capabilities, supported by our investments. In Connected Living, we made progress in expanding and supporting partnerships across mobile, extended service contracts and financial services. In mobile, subscriber growth remained strong, supported by the expansion of device protection programs globally, and we deepened key carrier relationships, including by signing a new agreement with a large U.S. mobile carrier. We expanded our reverse logistics business in mobile through a multi-year reverse logistics agreement and a dedicated logistics facility. In retail extended service contracts, we continued to build momentum across appliances and consumer electronics, and we saw strong progress in financial services as we scaled our card benefits business. In Global Automotive, we continue to expand and protect our position through new and renewed partnerships across distribution channels, including large dealer groups. We are also accelerating progress in heavy equipment and our leased and financed business. In Global Housing, we continued to outperform through policy growth in lender-placed, supported by a hardened voluntary homeowners’ insurance market and our success renewing key clients and winning new partnerships. Across the businesses, we are investing in technology, including AI, to transform our operations, support our clients and improve the customer experience.

In 2025, we made a series of strategic leadership appointments that leverage the strength of our executive bench and position us for continued long-term success. Effectiv

We face a multitude of cybersecurity threats from a range of adversaries. Our vendors, clients, distributors and other third parties with whom we work face similar cybersecurity threats, and a cybersecurity incident impacting us or any of these entities could materially adversely affect our business, operations, financial condition and results of operations.

Board Oversight

The Board has ultimate oversight of cybersecurity risk. The Board reviews and approves our ERM Framework and risk appetite annually, including the appropriate risk appetite with respect to cybersecurity. The Information Technology Committee of the Board reviews the effectiveness of our cybersecurity policies, controls, training, technology and procedures, including procedures to identify and assess internal and external risks from cybersecurity threats; controls to prevent and protect from cyberattacks, unauthorized access or other malicious acts and risks; procedures to detect, respond to, mitigate negative effects from and remediate cybersecurity attacks; and controls and procedures for fulfilling applicable regulatory reporting and disclosure obligations related to cybersecurity incidents, risks and costs. Our Chief Information Security Officer (“CISO”) briefs or provides a report to the Information Technology Committee on our cybersecurity and information security posture and program at least quarterly, including penetration test results and related remediation and significant cybersecurity incidents. Our CISO also provides an annual cybersecurity update to the full Board.

Role of Management

Cybersecurity risk is integrated into our Global Risk Management process. Cybersecurity risk continues to be identified as one of our key enterprise risks. Risk owners from the Management Committee, senior leadership and the Global Risk Management function have been assigned to develop risk mitigation plans, which are tracked and reported at least quarterly to the Finance and Risk Committee of the Board and annually to the full Board. See “Item 1 – Business – Global Risk Management” for more information on the Global Risk Management function.

Our CISO, who reports to our Chief Technology Officer on the Management Committee, has over 20 years of information technology and security program management experience, holds a Certified Information Security Manager certification and has led our information security team, including information technology compliance and risk management, since 2009. Our Chief Technology Officer has over 30 years of information technology experience, including leading global digital, security, infrastructure, cloud services and application teams. Prior to joining the Company in 2016, our Chief Technology Officer was chief information officer at a large, publicly-traded energy company.

Our CISO has implemented a management-level governance structure and process to assess, identify, manage and report cybersecurity risks, and to manage our overall information security program. The Information Security Board, led by our CISO and comprised of leaders from all of our lines of business and key functional areas such as Global Risk Management, Privacy and Compliance, as well as members of our information security team, meets quarterly, and is responsible for overseeing our information security program, including our information security strategy and related policies and standards. The information security team manages cybersecurity risks and controls, and continually enhances a global security control framework with the ultimate goal of preventing cybersecurity incidents to the extent feasible, while simultaneously minimizing the business impact should an incident occur.

Risk Management Policies and Procedures

We have implemented cybersecurity policies and standards based on leading industry frameworks, including the ISO 27001 standard and the National Institute of Standards and Technology Cybersecurity Framework, and we regularly assess our policies and practices, including through tabletop exercises with senior management (and periodically with members of the Board), aimed at mitigating cybersecurity risks. In the event of a cybersecurity incident, we follow our Enterprise Information Security Incident Response Plan (the “IRP”), which outlines steps from incident detection to assessment, response, mitigation, recovery and notification, including to key functional areas such as Global Risk Management, Corporate Law, Privacy and Compliance, senior leadership, and the Information Technology Committee of the Board and the full Board, as appropriate. The IRP includes quantitative and qualitative incident assessment guidance and promotes engagement with multidisciplinary teams across the enterprise to facilitate real-time information-sharing during a cybersecurity incident.

Employees outside of our information security team as well as third-party cybersecurity experts have an important role in our cybersecurity defenses. We require employees to participate in annual cybersecurity training and provide them with additional optional training and awareness materials, and we regularly engage our employees in phishing exercises, reporting results to the Information Technology Committee. In addition, we regularly engage assessors, consultants, auditors and other

third parties in our management of cybersecurity risk. For example, third parties are engaged to conduct evaluations of the maturity and effectiveness of our security program, including testing the design and operational effectiveness of security controls, penetration testing, engaging in independent audits, reviewing our policies and standards, and consulting on best practices to address new challenges. We also receive threat intelligence from government agencies, information sharing and analysis centers, and cybersecurity associations.

We assess third-party cybersecurity controls through a cybersecurity questionnaire and a review of independent cybersecurity rating assessments. Our vendor risk management process includes a review of the information security policies of our key vendors against our standards, and ongoing monitoring for compliance. Our contracts with third parties generally include security and privacy addendums where applicable and require counterparties to meet a specific standard of data security and to report cybersecurity incidents to us.

Risks from Cybersecurity Threats

While we have not experienced a cybersecurity incident that resulted in a material adverse effect on our business, operations, financial condition or results of operations, there can be no guarantee that we will not experience such an incident in the future. See “Item 1A – Risk Factors – Technology, Cybersecurity and Privacy Risks – The failure to effectively maintain and modernize our technology systems and infrastructure and integrate those of acquired businesses could adversely affect our business,” “ – Technology, Cybersecurity and Privacy Risks – We could incur significant liability if our technology systems or those of third parties are breached or we or third parties otherwise fail to protect the security of data residing on our respective systems, which could adversely affect our business and results of operations,” “ – Business Strategic and Operational Risks – Our inability to successfully recover should we experience a business continuity event could have a material adverse effect on our business, financial condition and results of operations” and “– Failure to successfully manage vendors and other third parties could adversely affect our business” for more information.

We own three properties. We have a shared headquarters building in Atlanta, Georgia, which serves as our corporate headquarters, as well as the headquarters for our Global Lifestyle and Global Housing businesses. In 2025, we entered into an agreement to sell our office in Miami, Florida, which had served as a shared office space supporting our Global Lifestyle and Global Housing businesses. Also in 2025, we sold one of our Global Housing operations centers located in Florence, South Carolina, and we started marketing for sale another operations center located in Springfield, Ohio. We lease office space and device care centers globally, with terms ranging from month-to-month to ten years. We believe that our owned and leased properties are sufficient to support our current business operations. See Notes 13 and 26 to the Consolidated Financial Statements included elsewhere in this Report for additional information about our properties. For more information on the Miami sale, see “Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources.”

For a description of any material pending legal proceedings in which we are involved, see “Commitments and Contingencies – Legal and Regulatory Matters” in Note 26 to the Consolidated Financial Statements included elsewhere in this Report, which is hereby incorporated by reference.

PART II

Our common stock is listed on the NYSE under the symbol “AIZ.” On February 13, 2026, there were approximately 221 registered holders of record of our common stock.

Stock Performance Graph

The following graph compares the cumulative total return (stock price increase plus reinvestment of dividends paid) on our common stock from December 31, 2020 through December 31, 2025 with the cumulative total returns for the S&P 400 MidCap Index and the S&P 500 Index, as the broad equity market indexes, and the S&P Composite 1500 Property & Casualty Insurance Index (“S&P 1500 P&C Index”), as the published industry index. The graph assumes that the value of the investment in our common stock and each index was $100 on December 31, 2020 and that all dividends were reinvested.

Total Values/Annual Return Percentages

(Includes reinvestment of dividends)

Issuer Purchases of Equity Securities

The table below provides information regarding purchases of our common stock during the fourth quarter of 2025.

(1)Shares purchased pursuant to the November 2023 publicly announced share repurchase authorization of up to $600.0 million aggregate cost at purchase of outstanding common stock. In November 2025, the Board authorized an additional share repurchase program for up to $700.0 million aggregate cost at purchase of outstanding common stock. As of December 31, 2025, $774.6 million aggregate cost at purchase remained unused under the repurchase authorizations.

Dividend Policy

Any determination to declare and pay future dividends will be at the sole discretion of the Board and will be dependent upon various factors, including: our subsidiaries’ payments of dividends and other statutorily permissible payments to us; our results of operations and cash flows; our financial condition and capital requirements; general business conditions and growth prospects; any legal, tax, regulatory and contractual restrictions on the payment of dividends; and any other factors the Board deems relevant. The Credit Facility also contains limitations on our ability to pay dividends to our stockholders and repurchase capital stock if we are in default, or such dividend payments or repurchases would cause us to be in default, of our obligations thereunder. In addition, if we elect to defer the payment of interest on our subordinated notes (refer to “— Senior and Subordinated Notes” below), we generally may not make payments on or repurchase any shares of our capital stock.

We are a holding company and, therefore, our ability to pay dividends on our common stock, repurchase shares or debt, service our debt and meet our other obligations depends primarily on the ability of our subsidiaries to pay dividends and make other statutorily permissible payments to us. Our insurance subsidiaries are subject to significant regulatory and other restrictions limiting their ability to pay dividends. See “Item 1A – Risk Factors – Financial Risks – Our subsidiaries’ inability to pay us sufficient dividends could prevent us from meeting our obligations and paying future stockholder dividends.” For the year ending December 31, 2026, the maximum amount of dividends our regulated U.S. domiciled insurance subsidiaries could pay us under applicable laws and regulations, without prior regulatory approval, is approximately $791.9 million. We may seek approval of regulators to pay dividends in excess of any amounts that would be permitted without such approval. There can be

no assurance that we would obtain such approval if sought. Our international and non-insurance subsidiaries provide additional sources of dividends. Dividends or returns of capital paid by our subsidiaries, net of infusions of liquid assets and excluding amounts used for acquisitions or received from dispositions, was approximately $925.1 million for the year ended December 31, 2025, of which $751.9 million was generated by our U.S. domiciled insurance subsidiaries.

Payments of dividends on shares of common stock are restricted if an event of default has occurred or if the proposed common stock dividend payment would cause an event of default under the Credit Facility; or if we defer the payment of interest on our Subordinated Notes. For more information, see “Item 1A – Risk Factors – Financial Risks – Our ability to declare and pay dividends on our capital stock may be limited” and “Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources.”

Securities Authorized for Issuance Under Equity Compensation Plans

See Item 12 of this Report for information about securities authorized for issuance under our equity compensation plans.

Not applicable.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our Consolidated Financial Statements and accompanying notes included elsewhere in this Report. It contains forward-looking statements that involve risks and uncertainties. Our actual results might differ materially from those projected in these forward-looking statements as a result of various factors, including those discussed below and elsewhere in this Report, particularly under the headings “Item 1A – Risk Factors” and “Forward-Looking Statements.”

General

Segment Information

As of December 31, 2025, we had two reportable operating segments which are defined based on the manner in which the Company’s chief operating decision maker, our CEO, reviews the business to assess performance and allocate resources, and which align to the nature of the products and services offered:

• Global Lifestyle: includes mobile device solutions (including extended service contracts, insurance policies and related services), extended service contracts and related services for consumer electronics and appliances, and financial services and other insurance products (referred to as “Connected Living”); and vehicle protection services, commercial equipment protection and other related services (referred to as “Global Automotive”); and

• Global Housing: includes lender-placed homeowners, manufactured housing and flood insurance, as well as voluntary manufactured housing, condominium and homeowners insurance (referred to as “Homeowners”); and renters insurance and other products (referred to as “Renters and Other”).

In addition, we report the Corporate and Other segment, which includes corporate employee-related expenses, activities of the holding company and investments in our home warranty business.

We define Adjusted EBITDA, our segment measure of profitability, as net income, excluding net realized gains (losses) on investments and fair value changes to equity securities, interest expense, benefit (provision) for income taxes, depreciation expense, amortization of purchased intangible assets, as well as other highly variable or unusual items (including restructuring costs, the loss on the pending subsidiary sale and non-core operations, each as described below).

The following discussion covers the year ended December 31, 2025 (“Twelve Months 2025”) and the year ended December 31, 2024 (“Twelve Months 2024”). For a more detailed comparative analysis, see the discussion that follows. Our comparative analysis of Twelve Months 2024 and the year ended December 31, 2023 is included under the heading “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 filed with the SEC on February 20, 2025.

Executive Summary

Summary of Financial Results

Consolidated net income increased $112.5 million, or 15%, to $872.7 million for Twelve Months 2025 from $760.2 million for Twelve Months 2024, primarily due to higher segment earnings in Global Housing, lower reportable catastrophes and growth in Global Lifestyle, partially offset by a higher effective tax rate and restructuring costs.

Global Lifestyle Adjusted EBITDA increased $27.9 million, or 4%, to $801.3 million for Twelve Months 2025 from $773.4 million for Twelve Months 2024, primarily driven by Connected Living growth from global mobile programs and higher contributions from financial services. In Global Automotive, improved loss experience led to increased profitability.

Global Lifestyle net earned premiums, fees and other income increased $615.2 million, or 7%, to $9.58 billion for the Twelve Months 2025 from $8.97 billion for Twelve Months 2024, primarily due to global mobile programs and from a new program in financial services within Connected Living and modest growth in Global Automotive.

Global Housing Adjusted EBITDA increased $187.5 million, or 28%, to $858.7 million for Twelve Months 2025 from $671.2 million for Twelve Months 2024, including $46.4 million of lower pre-tax reportable catastrophes. Excluding reportable catastrophes, Adjusted EBITDA increased 15% mainly due to top-line growth in lender-placed insurance and favorable non-catastrophe loss experience.

Global Housing net earned premiums, fees and other income increased $311.8 million, or 13%, to $2.77 billion for Twelve Months 2025 from $2.46 billion for Twelve Months 2024, primarily due to growth in policies in-force and higher average premiums within lender-placed insurance, as well as growth in various specialty products. Renters and Other also increased, led by contributions from a new book of business previously disclosed.

Corporate and Other Adjusted EBITDA was $(123.8) million for Twelve Months 2025 compared to $(122.2) million for Twelve Months 2024, primarily driven by lower investment income.

Critical Factors Affecting Results

Our results depend on, among other things, the appropriateness of our product pricing, underwriting, the accuracy of our reserving methodology for future policyholder benefits and claims, the frequency and severity of reportable and non-reportable catastrophes, returns on and values of invested assets, our investment income, and our ability to enhance operational efficiencies and manage our expenses. Our results also depend on our ability to profitably grow our businesses, including our Connected Living, Global Automotive and Renters businesses, and the performance of our Homeowners business, which will be impacted by our ability to provide a superior customer experience, including from our investments in technology and digital initiatives. Factors affecting these items, including conditions in the financial markets, the global economy, political conditions and the markets in which we operate, fluctuations in exchange rates, interest rates and inflation, and tariffs and global supply chain disruptions may have a material adverse effect on our results of operations or financial condition.

Our results may also be impacted by our ability to capitalize on opportunities for further growth, including within adjacent markets such as home warranty. Our mobile business is subject to volatility in mobile device trade-in volumes and margins based on the actual and anticipated timing of the release of new devices, carrier promotional programs and sales prices for used devices, as well as to changes in consumer preferences and client forecasts and demands. Our Homeowners revenue is impacted by changes in the housing market, as well as the voluntary insurance market. Variability in insurance claims, including changes in frequency and severity, and the impact of inflation, also contribute to fluctuations in our business performance. In addition, across many of our businesses, we must respond to competitive pressures, including the threat of disruption and competition for talent. For more information on these and other factors that could affect our results, see “Item 1A – Risk Factors,” including “ – Business, Strategic and Operational Risks – Significant competitive pressures, changes in customer preferences and disruption could adversely affect our results of operations,” “ – Our mobile business is subject to the risk of declines in the value and availability of mobile devices, and to regulatory compliance and other risks” and “ – The success of our business depends on the execution of our strategy, including through organic growth and the continuing service of key executives, senior leaders, highly-skilled personnel and a high-performing workforce.”

For Twelve Months 2025, net cash provided by operating activities was $1.83 billion; net cash used in investing activities was $1.46 billion; and net cash used in financing activities was $364.2 million. We had $1.83 billion in cash and cash equivalents as of December 31, 2025. See “ – Liquidity a

The following is a discussion of our primary market risk exposures and management of such exposures as of December 31, 2025. There were no other significant changes in our primary market risk exposures or in how those exposures were managed for the year ended December 31, 2025, compared to the year ended December 31, 2024. We do not currently anticipate significant changes in our primary market risk exposures or in how those exposures are managed in future reporting periods based upon what is known or expected to be in effect in future reporting periods.

Market risk is the risk of loss from changes in the fair value of our financial instruments, including due to interest rates (including impacts of changes in credit spreads), foreign currency exchange rates and credit risk from counterparties. Market risk is dependent on the volatility and liquidity in the underlying markets in which these assets are traded.

Our investment portfolio consists primarily of fixed maturity securities, denominated in both U.S. dollars and foreign currencies, which are sensitive to changes in interest rates, including impacts of changes in credit spreads, foreign currency exchange rates and credit risk from counterparties. The majority of our fixed income portfolio is classified as available for sale. The carrying value of our investment portfolio at December 31, 2025 and 2024 was $10.06 billion and $8.54 billion, respectively, of which 85% and 84% was invested in fixed maturity securities, respectively.

Interest Rate Risk

Interest rate risk is the possibility that the fair value of liabilities will change more or less than the market value of investments in response to changes in interest rates, including changes in investment yields and changes in spreads due to credit risks and other factors.

Our investment portfolio, including our fixed maturity portfolio, has exposure to interest rate risk. Changes in investment values attributable to interest rate changes are mitigated by corresponding and partially offsetting changes in the economic value of our liabilities. We monitor this exposure through periodic reviews of our asset and liability positions and we manage interest rate risk by selecting investments with characteristics such as duration, yield, currency and liquidity tailored to the anticipated cash outflow characteristics of our insurance and reinsurance liabilities. Portfolio duration is primarily managed through cash market transactions. For additional information, see Notes 7 and 9 to the Consolidated Financial Statements included elsewhere in this Report and “Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Investments”.

The interest rate sensitivity relating to changes in fair value in our fixed maturity portfolio is assessed using hypothetical scenarios that assume parallel shifts of the yield curves. Our actual experience may differ from the results indicated below, particularly due to the assumptions reflected or if events occur that were not included in the methodology. For more information, see “Item 1A – Risk Factors – Financial Risks – Actual results may differ materially from the analytical models we use to assist in our decision-making in key areas such as pricing, catastrophe risks, reserving and capital management.”

Our sensitivity analysis model produces a loss in fair value in the fixed maturity portfolio of (i) $216.5 million and $173.2 million as of December 31, 2025 and 2024, respectively, based on a hypothetical and instantaneous 50 basis point parallel increase in interest rates (including impacts of changes in credit spreads), and (ii) $428.5 million and $340.0 million as of December 31, 2025 and 2024, respectively, based on a hypothetical and instantaneous 100 basis point parallel increase in interest rates (including impacts of changes in credit spreads).

Our debt obligations also have exposure to interest rate risk, primarily at the time of refinancing. We monitor market interest rates and evaluate refinancing opportunities for our debt obligations as maturity dates approach. We stagger the maturity dates of our debt to mitigate the interest rate risk in any given year. For additional information, see Note 18 to the Consolidated Financial Statements included elsewhere in this Report and “Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources”.

Our sensitivity analysis model produces a loss in fair value of our debt obligations of (i) $52.2 million and $48.4 million as of December 31, 2025 and 2024, respectively, based on a hypothetical and instantaneous 50 basis point parallel increase in interest rates, and (ii) $102.7 million and $95.3 million as of December 31, 2025 and 2024, respectively, based on a hypothetical and instantaneous 100 basis point parallel increase in interest rates.

Foreign Exchange Risk

We are exposed to foreign exchange risk arising from our investments in foreign subsidiaries. Foreign exchange risk is the possibility that changes in exchange rates produce an adverse effect on earnings and equity when measured in domestic currency. This risk is largest when assets backing liabilities payable in one currency are invested in financial instruments of another currency. To manage foreign exchange risk, our general principle is to invest in assets that match the currency in which we expect liabilities to be paid. Foreign exchange risk is mitigated by matching our liabilities under insurance policies that are payable in foreign currencies with investments that are denominated in such currencies.

The foreign exchange risk sensitivity of the fair value of our investments in foreign subsidiaries is assessed using a hypothetical 10% immediate change in each of the foreign currency exchange rates to which we are exposed. The modeling technique we use to report our currency exposure does not take into account correlation among foreign currency exchange rates. Our actual experience may differ from the results indicated below, particularly due to the assumptions reflected or if events occur that were not included in the methodology. For more information, see “Item 1A – Risk Factors – Financial Risks – Actual results may differ materially from the analytical models we use to assist in our decision-making in key areas such as pricing, catastrophe risks, reserving and capital management” and “– Fluctuations in the exchange rate of the U.S. Dollar and other foreign currencies may materially and adversely affect our results of operations.”

The following table summarizes the net assets (liabilities) denominated in foreign currencies as of December 31, 2025 and 2024 and the sensitivity to a hypothetical strengthening of the U.S. dollar.

Credit Risk

Credit risk is the possibility that counterparties may not be able to meet payment obligations when they become due. A counterparty is any person or entity from which cash or other forms of consideration are expected to extinguish a liability or obligation to us. With respect to our market risk sensitive instruments, we have exposure to credit risk as a holder of fixed maturity securities.

Our risk management strategy and investment policy is to invest in securities from a diversified pool of issuers and to limit the amount of credit exposure with respect to any one issuer. We attempt to limit our credit exposure by imposing fixed maturity portfolio limits on individual issuers based upon credit quality, among other strategies. For additional information, refer to “Item 1A – Risk Factors – Financial Risks – Our investment portfolio is subject to credit, liquidity and other risks that may adversely affect our results of operations and financial condition,” “Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Investments” and Notes 4 and 7 to the Consolidated Financial Statements included elsewhere in this Report.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our CEO and our CFO, has evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15(b) or 15d-15(b) under the Exchange Act as of December 31, 2025. Based on such evaluation, management, including our CEO and CFO, has concluded that as of December 31, 2025, our disclosure controls and procedures were effective and provide reasonable assurance that information we are required to disclose in our reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms. Our CEO and CFO also have concluded that as of December 31, 2025, information that we are required to disclose in our reports under the Exchange Act is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for us as defined in Rule 13a-15(f) or 15d-15(f) under the Exchange Act.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. A company’s internal control over financial reporting includes policies and procedures that: (1) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management, with the participation of our CEO and CFO, evaluated the effectiveness of our internal control over financial reporting as of December 31, 2025 using criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Management, including our CEO and CFO, based on its evaluation of our internal control over financial reporting, has concluded that our internal control over financial reporting was effective as of December 31, 2025.

The effectiveness of our internal control over financial reporting as of December 31, 2025 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting during the quarterly period ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Assurant, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Assurant, Inc. and its subsidiaries (the "Company") as of December 31, 2025 and 2024, and the related consolidated statements of operations, of comprehensive income, of changes in stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2025, including the related notes and financial statement schedules listed in the index appearing under Item 15(a)(2) (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Annual Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevent
