**Report of Independent Registered Public Accounting Firm**

To the Plan Participants and Plan Administrator of

Sleep Number Profit Sharing and 401(k) Plan

**Opinion on the Financial Statements**

We have audited the accompanying statements of net assets available for benefits of Sleep Number Profit Sharing and 401(k) Plan (the "Plan") as of December 31, 2025 and 2024, the related statement of changes in net assets available for benefits for the year ended December 31, 2025, and 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 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.

**Report on Supplemental Schedule** 

The supplemental schedule of assets (held at end of year) as of December 31, 2025 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 compliance 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, such schedule is fairly stated, in all material respects, in relation to the financial statements as a whole.

**PROFIT SHARING AND 401(k) PLAN**

Notes to Financial Statements

As of December 31, 2025 and 2024 and for the Year Ended December 31, 2025

**(1) DESCRIPTION OF THE PLAN**

The following brief description of the Sleep Number Profit Sharing and 401(k) Plan (Plan), sponsored by Sleep Number Corporation (Plan Sponsor or the Company) provides only general information. Participants should refer to the Plan's summary plan description or official Plan documents for more complete information regarding the Plan's provisions.

***General*** – The Plan is a tax-qualified defined contribution plan covering all employees. The Plan is available to all common law employees of the Company who are eligible to enroll in the Plan on their date of hire. The Plan is subject to the provisions of the Internal Revenue Code and the Employee Retirement Income Security Act of 1974 (ERISA). The Plan's original effective date was January 1, 1994.

***Custodian and Recordkeeper*** – Plan assets are held by Charles Schwab Bank (Trustee, Custodian or Schwab). The Plan's third-party recordkeeper is Milliman, Inc. (Recordkeeper).

***Plan Administrator*** - The general administration of the Plan and the duty to carry out its provisions is vested in the Plan Administrator. The Audit Committee of the Plan Sponsor has delegated the governance powers and responsibilities with respect to the Plan to the Plan Administrator who also serves as the Senior Director, Total Rewards of the Plan Sponsor.

***Contributions*** – Each year, participants may contribute up to a maximum of 50% of eligible earnings on a pre-tax and/or after-tax Roth basis, as defined by the Plan. Participants who have attained age 50 before the end of the calendar year are eligible to make catch-up contributions (pre-tax or after-tax Roth). Participants may also make rollover contributions to the Plan of distributions they received from other employers' tax-qualified retirement plans. Beginning in 2022 through October 9, 2025, the Company's matching contributions were changed to comply with Internal Revenue Service (IRS) requirements for safe harbor 401(k) plans. As of October 10, 2025, the Company amended the Plan to remove the safe harbor designation and also suspended the Company's matching contribution of participants' eligible earnings. Between January 1, 2025 and October 9, 2025, the Company matched 100% of the first 4% of participants' eligible earnings. Company matching contributions for 2025, net of forfeitures, were $5,293,825 prior to the suspension of the company match. The Company may also make additional profit-sharing contributions at the discretion of the Company's Board of Directors. No profit-sharing contributions were made in 2025.

***Participant Accounts*** – Individual accounts are maintained for each Plan participant. Each participant's account is credited with the participant's contributions, the Company's matching contributions, if applicable, and Plan earnings.

***Vesting*** – Participants are immediately vested in their own contributions to the Plan plus actual earnings thereon. For participant contributions made beginning in 2022, the Company's matching contributions are immediately vested. The vesting on the Company's matching contributions on participant contributions prior to 2022 plus actual earnings thereon is based on years of service. Participants are vested 25% upon the completion of one year, 50% after two years, 75% after three years, and fully vested after completion of four years of service, upon death or disability, or upon termination of employment after reaching the Plan's normal retirement age (65).

***Forfeitures*** – Forfeitures from non-vested accounts are used to either reduce Company matching contributions or to pay Plan administrative expenses. The forfeiture balances as of December 31, 2025 and 2024 were $256,253 and $123,913, respectively. Forfeitures were used to pay administrative expenses of $139,377 in 2025.

***Notes Receivable*** *–* ***Participants*** – A participant who is employed with the Company may borrow from their vested Plan accounts, a minimum loan amount of $1,000 up to a maximum loan equal to the lesser of $50,000, or 50% of the participant's vested account balance. Loans are made on a pro-rata basis from all investment funds in which a participant's account is invested. Loan terms range from one to five years or up to 15 years for the purchase of the participant's primary residence. The loans are secured by the participant's account. Loans bear interest at the prime rate plus one percentage point (ranging from 4.25% to 9.50% at both December 31, 2025 and 2024). Principal and interest are paid ratably through payroll deductions each payroll period.

Notes receivable from participants are measured at their unpaid principal balances plus any accrued unpaid interest. Delinquent notes receivable from participants are reclassified as distributions based upon the terms of the plan document. Notes receivable from participants are valued at amortized cost, which approximates fair value. No allowance for credit losses has been recorded as of December 31, 2025 or 2024.

As of December 31, 2025 and 2024 and for the Year Ended December 31, 2025

***Investment Options*** – Participants may direct investment of their account balances in any of the Plan's designated investment fund options (which also includes Company common stock) or a self-directed brokerage account. Participants may modify their investment fund elections daily.

***Payment of Benefits*** – Upon termination of employment (including due to death, disability or retirement), a participant may receive a distribution of their vested account balance in the form of a single lump-sum payment, installment payments or non-periodic payments, subject to certain Plan restrictions. A participant may elect to rollover that distribution into another employers' tax-qualified retirement plan or the participant's individual retirement account. A participant may also elect to withdraw some or all of their vested account balances prior to termination of employment under certain Plan in-service withdrawal provisions. Amounts allocated to accounts of persons who have elected to withdraw from the Plan, but have not yet been paid, were $106,637 and $57,108 as of December 31, 2025 and 2024, respectively, and are included in accrued expenses in the Statements of Net Assets Available for Benefits.

***Administrative Expenses*** – Certain expenses of maintaining the Plan are paid by the Plan, unless otherwise paid by the Company. Expenses that are paid by the Company are excluded from these financial statements. Fees related to the administration of notes receivable from participants and fees paid related to benefits paid to participants are charged directly to the participant's account and are included in administrative expenses. Recordkeeping fees, legal fees, audit fees, trustee fees and other reasonable costs of administering the Plan may be paid with Plan assets. Investment related expenses are included in net appreciation (depreciation) of fair value of investments in the Statement of Changes in Net Assets Available for Benefits.

***Legislation*** - In December 2022, Securing a Strong Retirement Act (SECURE 2.0) was passed into law. This package of laws builds on the Setting Every Community Up for Retirement Enhancement (SECURE) Act of 2019. SECURE Act 2.0 covers numerous changes to retirement provisions designed to increase retirement savings, facilitate access to retirement savings, encourage employees to save for retirement, and lower employers' cost of offering and funding retirement savings plans. The provisions include both required and optional elements and the Plan Administrator will determine the optional provisions to elect. The United States Department of the Treasury and the Internal Revenue Service continue to issue guidance and regulations implementing provisions of SECURE 2.0. The deadline for amending plan documents has been extended to December 31, 2026, as such, the Plan sponsor is currently evaluating the provisions of SECURE 2.0 and related guidance to determine the full impact to the Plan and participants.

**(2) SIGNIFICANT ACCOUNTING POLICIES**

***Basis of Presentation*** – The accompanying financial statements of the Plan are prepared under the accrual method of accounting in accordance with United States generally accepted accounting principles (GAAP).

The preparation of financial statements in conformity with United States GAAP requires management to make estimates and assumptions that affect the reported amounts of net assets available for benefits and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of changes in net assets available for benefits during the reporting period. Predicting future events is inherently an imprecise activity and as such requires the use of judgment. Future results could be materially affected if actual results differ from these estimates and assumptions.

***Investment Valuation and Income Recognition*** – The Plan's investments are stated at fair value, which is the price that would be received to sell an asset in an orderly transaction between market participants at the measurement date. See [Note 4,](#i979f3d14f7b94c1a9be2acc2e6d0ee1f_31)*[Fair Value Measurements](#i979f3d14f7b94c1a9be2acc2e6d0ee1f_31)*, for the disclosure of the Plan's fair value measurements.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Net appreciation (depreciation) includes the Plan's gains and losses on investments bought and sold, as well as held during the year.

***Payment of Benefits*** – Benefit payments are recorded upon distribution.

***Risks and Uncertainties*** – The Plan provides for investment, at the participant's option, in any combination of the Company's common stock, investment funds, collective trusts or a self-directed brokerage account which enables participants to invest in mutual funds or publicly traded stocks with a share value of greater than $5.00. Investment securities are exposed to various risks, such as interest rate, credit and overall market volatility. Market risks include global events, such as a pandemic, or international conflict, which could impact the value of investment securities. Due to

Notes to Financial Statements

As of December 31, 2025 and 2024 and for the Year Ended December 31, 2025

the level of risk and uncertainty, it is reasonably possible that changes in the values of the investments will occur in the near term, and such changes could materially affect participants' account balances and the amounts reported in the statements of net assets available for benefits and the statement of changes in net assets available for benefits.

***Concentration of Market Risk*** – As of both December 31, 2025 and 2024, approximately 1% of the Plan's net assets available for benefits were invested in the common stock of the Company. The Plan purchased $2.6 million and sold $0.8 million of the Company's common stock during 2025. As of December 31, 2025 and 2024, the Plan held 423,865 and 303,939 shares of the Company's common stock with a cost basis of $9,980,612 and $11,240,967, respectively. The underlying value of the Company's common stock is dependent upon the performance of the Company and the market's evaluation of such performance.

During the year ended December 31, 2025, the Plan's investment in the Company Stock Fund experienced a significant decrease in fair value due to a decline in the market price of the Company's common stock. The Company's stock price decreased 44% during 2025.

Subsequent to December 31, 2025, the market price of the Company's common stock declined materially. From January 1, 2026 through June 15, 2026, the stock price decreased 95%. Had this decline occurred as of year end, the fair value of the Plan's investment in Company stock would have decreased by $3.4 million. Management evaluated this event and determined that disclosure was appropriate; however, no adjustment to the accompanying financial statements has been made as the event occurred after the balance sheet date.

As of December 31, 2025 and 2024, the Plan also had $65.3 million and $63.3 million, respectively, invested in one fund that represented 10% or more of the Plan's net assets available for benefits. This fund, Fidelity 500 Index Fund, represented 24% and 25% of the Plan's net assets available for benefits as of December 31, 2025 and 2024, respectively.

***Plan Termination*** *– A*lthough it has not expressed any intent to do so, the Company has the right under the Plan to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100% vested in their accounts.

***Subsequent Events*** *–* Events that have occurred subsequent to December 31, 2025 have been evaluated through the date these financial statements were issued.

On June 12, 2026, Sleep Number Corporation and its subsidiaries (together with Sleep Number, the "Debtors"), filed voluntary petitions for relief under Chapter 11 of title 11 of the U.S. Bankruptcy Code in the United States Bankruptcy Court for the Southern District of New York. Management evaluated this event and determined that it represents a nonrecognized subsequent event. The Plan has not been amended as a result of the filing, and, as of the date the financial statements were available to be issued, no changes to Plan benefits, eligibility, or administrative processes had been made. Management is evaluating the effect of the bankruptcy filing on the Plan, including any impact on amounts due from the plan sponsor or sponsor-related matters. Management does not believe the filing has had a material effect on the Plan.

**(3) INCOME TAX STATUS**

The Plan has received a favorable determination letter from the Internal Revenue Service dated October 30, 2017 indicating that the Plan is designed in accordance with applicable sections of the Internal Revenue Code (Code). The Plan has been amended since receiving the determination letter. However, the Plan Administrator believes that the Plan is currently designed and being operated in compliance with the applicable requirements of the Code. Therefore, no provisions for income taxes have been made.

United States GAAP requires plan management to evaluate uncertain tax positions taken by the Plan. The financial statement effects of a tax position are recognized when the position is more likely than not, based on the technical merits, to be sustained upon examination by the Internal Revenue Service. The Plan Administrator has analyzed the tax positions taken by the Plan and has concluded that, as of December 31, 2025 and 2024, there are no uncertain tax positions taken or expected to be taken. The Plan has not recognized any interest or penalties related to uncertain tax positions. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan is currently open to audit under the statute of limitations by the IRS for the 2022 through 2024 tax years.

**(4) FAIR VALUE MEASUREMENTS**

The Financial Accounting Standards Board's (FASB's) guidance for fair value measurements establishes the authoritative definition of fair value, sets out a framework for measuring fair value and outlines the required disclosures regarding fair value measurements. Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Plan management uses a three-tier fair value hierarchy based upon observable and non-observable inputs as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1 – observable inputs such as quoted prices in active markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2 – inputs, other than the quoted prices in active markets, that are observable either directly or indirectly, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Quoted prices for similar assets or liabilities in active markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Quoted prices for identical or similar assets in nonactive markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Inputs other than quoted prices that are observable for the asset or liability;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Inputs that are derived principally from or corroborated by other observable market data; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3 – unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Outlined below are descriptions of the valuation methodologies used to measure assets at fair value. There have been no changes in the methodologies used as of December 31, 2025 compared with the prior year.

**Mutual Funds** – The fair value of mutual funds are determined by net asset value (NAV) of shares held by the Plan on the last trading day of the Plan year based on quoted market prices.

**Collective Investment Trusts (CIT)** –The Plan uses NAV per share of the funds provided by the Trustees of each respective fund as a practical expedient to estimate fair value. The practical expedient would not be used if it is determined to be probable that the fund would sell the investment for an amount different from the reported NAV. Participant transactions (purchases and sales) may occur daily. If the Plan initiates a full redemption of the fund, the trustee reserves the right to require 12 months' notification in order to ensure that securities liquidations will be carried out in an orderly business manner. The fund's units are issued and redeemed daily at the constant NAV of $1 per unit.

**Sleep Number Corporation Common Stock** – Sleep Number Corporation common stock is valued at the quoted market price on the last trading day of the Plan year.

**Self-Directed Brokerage Account** – The fair value of the individual investments are valued at the NAV of shares held by the Plan on the last trading day of the Plan year based on quoted market prices.

The valuation methods described could result in fair values that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Plan Administrator believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.
