**Report of Independent Registered Public Accounting Firm**

To the Administrator and Plan Participants of Assurant 401(k) Plan

***Opinion on the Financial Statements***

We have audited the accompanying statements of net assets available for benefits of Assurant 401(k) Plan (the "Plan") as of December 31, 2025 and 2024 and the related statement of changes in net assets available for benefits for the year ended December 31, 2025, including the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2025 and 2024, and the changes in net assets available for benefits for the year ended December 31, 2025 in conformity with accounting principles generally accepted in the United States of America.

***Basis for Opinion***

These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on the Plan's financial statements 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 Plan 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 of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

***Supplemental Information***

The supplemental Schedule H, Line 4(i) – Schedule of Assets (Held at End of Year) as of December 31, 2025 ("supplemental schedule") has been subjected to audit procedures performed in conjunction with the audit of the Plan's financial statements. The supplemental schedule is the responsibility of the Plan's management. Our audit procedures included determining whether the supplemental schedule reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental schedule. In forming our opinion on the supplemental schedule, we evaluated whether the supplemental schedule, including its form and content, is presented in conformity with the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental schedule is fairly stated, in all material respects, in relation to the financial statements as a whole.

**Assurant 401(k) Plan**

**Notes to Financial Statements**

**December 31, 2025 and 2024**

**1. Description of the Plan**

The following description of the Assurant 401(k) Plan ("the Plan") provides general information only. Participants should refer to the Plan document for a more complete description of the Plan's provisions. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA").

a.*General*. The Plan is a defined contribution retirement plan covering all eligible employees of Assurant, Inc. (the "Company", "Employer" or "Plan Sponsor") and its subsidiaries. The Plan became effective June 21, 1983. The Plan Administrator is the Employer's Benefit Plans Committee.

The Vanguard Fiduciary Trust Company ("Vanguard") acts as the recordkeeper and Trustee of the Plan. The investments are held in a nondiscretionary trust (the "Trust").

b.*Contributions.* Participants direct the investment of all contributions into various investment options offered by the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;i.Employee Contributions - Eligible employees are allowed to participate in the Plan 30 days after beginning employment. Eligible employees are automatically enrolled at a 3% pre-tax contribution rate. Employees have the option to elect a different contribution rate or to opt out of the automatic contributions. Additionally, employees who are contributing less than 15% to the Plan on a pre-tax basis are automatically enrolled in the annual increase program, which increases their pre-tax contribution rate in March of each year by one percent until their pre-tax contribution rate reaches 15%. Employees have the option to opt out of the automatic annual increase program. Each participant may elect to make contributions to the Plan on a pre-tax and/or Roth basis through payroll deductions from 1% through 50% of such participant's eligible compensation for each pay period up to an annual maximum of $23.5 thousand for 2025. In addition, participants who are age 50 or older and have made the maximum contribution to the Plan could make an additional catch-up contribution to the Plan. For 2025, participants age 50-59 or age 64 or older may contribute up to an additional $7.5 thousand, while participants age 60-63 may contribute up to an additional $11.25 thousand. Participants can change the rate at which they contribute at any time during the year. Participants may also make rollover contributions from other eligible qualified plans, including former employer plans and individual retirement account or annuity, to the extent permitted under the Plan and applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;ii.Employer Contributions - Participants are immediately eligible for the Employer matching contribution, which is based on a uniform calculation of 100% of employee deferrals up to 6% of eligible pay contributed by the participant on a pre-tax basis and/or Roth basis. These contributions are made through the bi-weekly payroll process. To ensure that each eligible employee receives the maximum eligible Company match, a true-up Employer matching contribution is made as of year-end for 2025.

&nbsp;&nbsp;&nbsp;&nbsp;iii.Profit-Sharing Contributions - The Plan was amended in 2016 to allow the grant of discretionary profit-sharing contributions.

c.*Participant Accounts*. Individual accounts are maintained for each Plan participant. Each participant's account is credited with employee contributions, Employer contributions and investment earnings and charged with the allocation of investment losses and an allocation of administrative and investment management expenses.

d.*Vesting*. A participant becomes 100% vested in their Employer contribution account upon two years of vesting service. In addition, a participant becomes 100% vested when they reach normal or early retirement date, terminate by reason of total disability or if they die while employed by the Employer.

e.*Participant Loans.* Participants may borrow a minimum of $500 up to a maximum equal to the lesser of $50 thousand from their fund accounts, reduced by the highest outstanding balance of loans taken in the previous 12 months, and 50% of their vested account balance. Loans must generally be repaid within 5 years or up to 10 years for the purchase of a primary residence. The loans are collateralized by the balance in the participant's account and bear interest at a rate of 1.0% above the prime rate (as reported by Reuters) in effect when the participant applies for the loan. At December 31, 2025, outstanding participant loans had interest rates ranging from 4.25% to 9.50%. Principal and interest are paid ratably through payroll deductions. Loan origination and annual maintenance fees on loans are paid by the loan participants. The maximum number of loans a participant is permitted to have outstanding at one time is two loans. Effective January 1, 2025, participants who are on an authorized leave of absence or are disabled shall not be able to request a loan from the

**Notes to Financial Statements**

**December 31, 2025 and 2024**

Plan while absent.

f.*Payment of Benefits*. Upon retirement, death or disability, Plan participants or their beneficiaries are entitled to receive the total amount in the participant's account. Upon termination of employment for other than the aforementioned reasons, Plan participants are eligible to receive their contributions and their vested share of Employer contributions plus income (loss) accrued thereon, if any.

g.*In-Service Withdrawals.* Both hardship and non-hardship withdrawals are permitted under a variety of circumstances as approved by the Plan Administrator.

h.*Forfeitures*. Forfeited balances of terminated participants' non-vested accounts shall be first applied to reduce employer contributions. Next, forfeitures may be used to restore previously forfeited amounts of rehired participants. Any remaining forfeitures may be applied to pay the Plan's administrative expenses. For the year ended December 31, 2025, the amount of forfeitures used to reduce administrative expenses and Employer contributions was $2.0 million. As of December 31, 2025, the remaining forfeitures balance was $1.4 million.

**2. Significant Accounting Policies**

*Basis of Accounting* 

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The financial statements of the Plan have been prepared under the accrual basis of accounting.

*Use of Estimates* 

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

*Investment Valuation* 

The Plan uses an exit price for its fair value measurements. An exit price is defined as the amount received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In measuring fair value, the Plan gives the highest priority to unadjusted quoted prices in active markets for identical assets and the lowest priority to unobservable inputs.

Investment securities are stated at fair value. Such investment securities are composed of shares of mutual funds, collective investment trusts and money market funds, all of which are valued at their year-end net asset value, and Assurant, Inc. common stock, which is valued at its year-end closing price. The net asset value is based on the closing market prices of the securities in the investment vehicle's portfolio.

*Participant Loans* 

Notes receivable from participants are related to participant loans and are stated at their unpaid principal balances plus any accrued but unpaid interest. Interest income is recorded on an accrual basis. Delinquent notes receivable are considered to be deemed distributions and reclassified as participant withdrawals based upon the terms of the Plan document.

*Income Recognition* 

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded as earned on an accrual basis. Dividends are recorded on the ex-dividend date.

Net appreciation in the fair value of investments includes realized gains/losses for securities sold as well as the change in unrealized gains/losses for securities held at year-end. Realized gains/losses from security transactions are recorded on the average cost method.

*Payment of Benefits* 

Benefit payments are recorded when paid to participants. There were no amounts allocated to accounts of persons who have elected to withdraw from the Plan but have not yet been paid at December 31, 2025.

**Notes to Financial Statements**

**December 31, 2025 and 2024**

**3. Fair Value Measurements** 

The fair value measurements and disclosures guidance defines fair value and establishes a framework for measuring fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In accordance with this guidance, the Plan has categorized its recurring fair value basis financial assets into a three-level fair value hierarchy based on the priority of the inputs to the valuation technique.

The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets (Level 1) and the lowest priority to unobservable inputs (Level 3). The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Plan's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and takes into account factors specific to the asset.

The levels of the fair value hierarchy are described below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets that the Plan can access.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2 inputs utilize other than quoted prices included in Level 1 that are observable for the asset, either directly or indirectly, for substantially the full term of the asset. Level 2 inputs include quoted prices for similar assets in active markets, quoted prices for identical or similar assets in markets that are not active and inputs other than quoted prices that are observable in the marketplace for the asset. The observable inputs are used in valuation models to calculate the fair value for the asset.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3 inputs are unobservable but are significant to the fair value measurement for the asset and include situations where there is little, if any, market activity for the asset. These inputs reflect the Plan's own assumptions about the assumptions a market participant would use in pricing the asset.

A review of the fair value hierarchy classifications is conducted on an annual basis. Changes in the observability of valuation inputs may result in a reclassification of levels for certain assets within the fair value hierarchy. In such instances, the transfer between levels is reported at the beginning of the reporting period.

The following table presents the Plan's fair value hierarchy for assets measured at fair value on a recurring basis as of December 31, 2025.

**Assurant 401(k) Plan**

**Notes to Financial Statements**

**December 31, 2025 and 2024**

Three different valuation techniques can be used in determining fair value for financial assets: the market, income or cost approaches. The three valuation techniques described in the fair value measurements and disclosures guidance are consistent with generally accepted valuation methodologies. For all the classes of financial assets included in the above hierarchy, the Plan uses the market approach. The market approach valuation techniques use prices and other relevant information generated by market transactions involving identical or comparable assets. When possible, quoted prices (unadjusted) in active markets are used as of the period-end date (such as for mutual funds, money market funds and common stock).

While not all three approaches are applicable to all financial assets, where appropriate, the Plan may use one or more valuation techniques. For the years ended December 31, 2025 and 2024, the application of the valuation technique applied to the Plan's classes of financial assets has been consistent.

<u>Level 1 Assets</u>:

The Plan's assets classified as Level 1 as of December 31, 2025 and 2024 consisted of mutual funds, money market funds and common stock that are publicly listed and/or actively traded in an established market.

<u>Level 2 Assets</u>:

The Plan's assets classified as Level 2 as of December 31, 2025 and 2024 consisted of collective investment trusts established for employee benefit plans. Plan management has determined that the trusts have a readily determinable fair value because the trusts' fair values are based on the end of day net asset value per unit which is published daily and observable to the Plan and its Participants through Vanguard's online portal and is the basis for current transactions. The units of the trusts may be redeemed daily and there are no restrictions on redemptions.

The Plan Sponsor evaluates the following factors in order to determine whether the market for a financial asset is inactive. The factors include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether there are few recent transactions,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether little information is released publicly,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the available prices vary significantly over time or among market participants,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the prices are stale (i.e., not current), and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the magnitude of the bid-ask spread.

Illiquidity did not have an impact in the fair value determination of the Plan's financial assets as of December 31, 2025 and 2024.

The Plan Sponsor obtains one price for each investment. The Plan Sponsor reviews the month-end prices received from the Plan administrator for the Plan's investments to validate that the month-end net asset value was used to price each investment. As a result of this analysis, if the Plan Sponsor determines that the month-end net asset value was not used by the Plan administrator to price the Plan's investments based upon available market data, which happens infrequently, the price of the investment would be adjusted accordingly.

**4. Income Tax Status** 

The Plan has received a determination letter from the Internal Revenue Service dated October 16, 2014, stating that the Plan is qualified under section 401(a) of the Internal Revenue Code (the "Code") and, therefore, the related trust is exempt from taxation. Once qualified, a plan is required to operate in conformity with the Code to maintain its qualification.

The Plan has been amended since receiving this determination letter. However, the Plan Sponsor believes that the Plan is designed and is currently being operated in compliance with applicable requirements of the Code and that the Plan is qualified, and the related trust is therefore tax exempt. Since the trust is exempt from taxation, there are no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements.

The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan Sponsor believes it is no longer subject to income tax examinations for years prior to 2022.

**December 31, 2025 and 2024**

**5. Plan Termination** 

The Company reserves the right to terminate the Plan at any time, subject to Plan provisions, though no such termination is planned. Upon such termination of the Plan, the interest of each participant in the Trust will be distributed to such participant or his or her beneficiary at the time prescribed by the Plan terms and the Code. Upon termination of the Plan, the Benefit Plans Committee shall direct the Trustee to pay all liabilities and expenses of the Trust. In the event of Plan termination, all participants would become 100% vested in all of their accounts.

**6. Related Parties** 

Certain Plan investments are shares of collective investment trusts, mutual funds and money market funds managed by the Trustee and, therefore, the buying and selling of such investments would qualify as party-in-interest transactions. The total market value of the Plan's allocated portion of the investments managed by the Trustee was $1,855.6 million, or 78%, and $1,619.9 million, or 76%, at December 31, 2025 and 2024, respectively. During 2025, the Plan's allocated portion of interest and dividend income, realized gains (losses) and unrealized gains (losses) from investments managed by the Trustee was $21.0 million, $65.6 million and $181.9 million, respectively.

The Northern Trust Company, a Custodian of the Plan, manages a short-term collective investment trust fund held by the Plan and, therefore, the buying and selling of such investments would qualify as party-in-interest transactions. The total market value of the Plan's allocated portion of the investments managed by the Custodian was $226 thousand and $228 thousand at December 31, 2025 and 2024, respectively. During 2025, the Plan's allocated portion of interest and dividends from investments managed by the Custodian was not material.

For the year ended December 31, 2025, maintenance fees paid to Vanguard by Plan participants totaled $875 thousand. This amount is included as part of administrative expenses on the Statement of Changes in Net Assets Available for Benefits.

The Plan Sponsor pays for certain expenses related to the Plan, including asset management fees to registered investment companies other than Vanguard, audit fees and legal fees. Expenses that are paid by the Plan Sponsor are excluded from these financial statements.

A participant may change the investment of any portion of the participant's account that is invested in Assurant, Inc. common stock into one or more other investment funds at any time in accordance with Plan rules. Participants of the Plan may transfer up to 25% of their current account balance into Assurant, Inc. common stock as well as allocate up to 25% of future contributions to Assurant, Inc. common stock.

Each participant who has any portion of their account invested in Assurant, Inc. common stock may elect to have dividends paid on Assurant, Inc. common stock held in their account either paid directly to the participant in cash or to have such dividends reinvested in Assurant, Inc. common stock. Each participant will always be 100% vested in any cash dividends that the participant elects to have either reinvested in Assurant, Inc. common stock or paid in cash to the participant. If a participant fails to make such an election, dividends paid on the Assurant, Inc. common stock will be reinvested in Assurant, Inc. common stock.

At December 31, 2025 and 2024, the Plan held 208,201 shares and 221,470 shares, respectively, of Assurant, Inc. common stock, with a fair value of $50.1 million and $47.2 million, respectively.

**7. Risks and Uncertainties**

Investment securities are exposed to various risks, such as interest rate fluctuations, market volatility and credit quality. The market, credit, investment and liquidity risks associated with each of the investment securities in which the Plan invests are described in the prospectus and statements of additional information for each of the mutual funds and collective investment trusts (together, the "funds/trusts"). The Plan is subject to such risks as a result of its investment in the funds/trusts. It is reasonably possible that real, threatened or perceived changes to these risks could materially affect the account balances of participants and the amounts reported in the Statements of Net Assets Available for Benefits and the Statement of Changes in Net Assets Available for Benefits.

The price of securities held by the funds/trusts may decline in response to certain events, including those directly involving the companies whose securities are owned by the funds/trusts; conditions affecting the general economy; overall

market changes; local, regional or global political, social or economic instability; cyber incidents; and currency, interest rate and commodity price fluctuations. The growth-oriented, equity-type securities generally purchased by the funds/trusts may involve large price swings and potential for loss.

Investments in securities issued by entities based outside the United States may be subject to the risks described above and may also be affected by foreign exchange; different accounting, auditing, financial reporting and legal standards and practices in some countries; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. These risks may be heightened in connection with investments in developing countries.
