REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Plan Administrator and Plan Participants

Brunswick Retirement Savings Plan

Opinion on the financial statements

We have audited the accompanying statements of net assets available for benefits of Brunswick Retirement Savings 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. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion.

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 schedule of assets (held at end of year) as of December 31, 2025 (“supplemental information”) has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental information 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 information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, 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 information is fairly stated, in all material respects, in relation to the financial statements as a whole.

Brunswick Retirement Savings Plan

Notes to Financial Statements

December 31, 2025 and 2024

1. Description of the Plan

The following description of the Brunswick Retirement Savings Plan (the "Plan") provides only general information. Brunswick Corporation (the "Company" or "Employer") is the Plan's sponsor. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.

General

The Plan, established by the Company effective January 1, 1986, is a defined-contribution plan subject to the requirements of the Employee Retirement Income Security Act of 1974 ("ERISA"), as amended. Any related company, as defined in the Plan, may, with the Company’s consent, adopt the Plan. The Plan is administered by the Benefits Administration Committee, consisting of at least three members appointed for indefinite terms by the Company’s Board of Directors. Certain investment assets of the Plan are held in the Brunswick Corporation Master Trust (the "Master Trust") at Vanguard Fiduciary Trust Company (the "Trustee"). Vanguard Fiduciary Trust Company is the Trustee of the Plan for all investment assets under an agreement with the Company.

Participation

Eligible employees include all groups under the terms of the Plan.

Eligible employees under the terms of the Plan, who are not eligible to participate in the Brunswick Rewards Plan, a separate plan sponsored by the Company, must be at least 18 years of age and employed by the Company or a related company to which the Plan has been extended. Prior to January 1, 2025, eligible participants in the IBB Union in Lowell, Michigan had to be at least 21 years of age to participate in the Plan.

Employees are immediately eligible to participate in the Plan upon reaching the age requirement. Prior to January 1, 2025, eligible participants in the IBB Union in Lowell, Michigan and IAM Union employees in Brookfield, Wisconsin, working at least 30 hours per week were eligible to participate in the Plan on the first day of the month following or coinciding with 60 days of employment. Employees working less than 30 hours per week are eligible to participate on the first day of the month following or coinciding with 12 months of employment. Employees can generally increase, decrease, or cancel their deferrals at any time.

Participant Accounts

Each participant’s account is credited with the participant’s contributions and allocations of: (a) the Company’s contributions, (b) the Plan’s earnings (losses), and (c) charged with an allocation of administrative expenses and, where applicable, specific transaction-based fees to participants who incur such transactions. Allocations are based on participant earnings or account balances, as defined in the Plan. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s account balances.

Participants may direct their own contributions and related Company contributions into any of the Plan’s fund options. Participants may generally change their elections and transfer balances between funds at any time.

Contributions

Participants may make pre-tax or Roth contributions from 1% to 40% of compensation as defined in the Plan. Contributions are made via payroll deductions and are remitted to the Trustee on the earliest date on which funds can be segregated from the Company’s funds. Participants who have attained age 50 before the end of the Plan year are eligible to make catch-up contributions. In 2025, pre-tax and Roth contributions were subject to the Internal Revenue Service ("IRS") limit of $23,500 and catch-up contributions were subject to the IRS limit of $7,500. Effective January 1, 2025, catch-up contributions for participants ages 60 through 63 were subject to the IRS limit of $11,250.

Brunswick Retirement Savings Plan

Notes to Financial Statements

December 31, 2025 and 2024

Subject to certain limitations, the Company makes matching contributions on a per-pay check basis equal to 100% of the first 3% of participant contributions plus 50% of the next 2% of contributions. Prior to January 1, 2025, eligible participants in the IAM Union in Brookfield, Wisconsin received Company matching contributions of 50% of participant deferrals, up to 6% of eligible compensation. These contributions are invested in accordance with the participant’s investment elections.

The Plan provides a true-up feature, which allows the Company to make up for any missed match resulting from the difference between the per payroll calculation performed throughout the year and the annualized amount due under the terms of the Plan. The true-up is performed during the first quarter of the following plan year and takes into account the maximum matching contribution that could have been received and makes up for any difference in comparison to the matching contributions that were actually made. For the years ended December 31, 2025 and 2024, the Company contributed $46,345 and $51,990 to the Plan, respectively, relating to the true-ups of certain participant accounts. These amounts are included as Employer contributions receivable (net of forfeitures) in the accompanying Statements of Net Assets Available for Benefits.

Forfeited balances of participants' nonvested accounts are used to reduce future Company contributions or to pay administrative expenses incurred by the Plan. At December 31, 2025 and 2024, forfeited nonvested accounts totaled $3,824 and $13,352, respectively. All of the forfeited nonvested accounts at December 31, 2024 were used to reduce employer contributions or pay Plan administrative expenses during 2025.

Vesting

Participants are required to complete two years of service to become fully vested in employer matching contributions. Eligible participants in the IAM Union in Fond du Lac, Wisconsin hired before January 1, 2019; the IBB Union in Lowell, Michigan hired before July 1, 2024; and the IAM Union in Brookfield, Wisconsin hired before January 1, 2025, are fully vested in their accounts at all times.

Notes Receivable from Participants

Active participants may borrow from their interest in the funds held by the Trustee. The minimum loan amount is $1,000. The maximum loan amount is the lesser of half of the participant's account balance or $50,000 less the largest balance of all loans in the prior 12 months, limited to participant contributions and rollovers only. Generally, a participant is not permitted to have more than one loan outstanding at any one time.

Participant loans bear interest, are secured by the participants’ accounts, and are payable over a period not to exceed five years unless the loan is for the purchase of a primary home, in which case, the loan term may be up to 10 years. The interest rate on loans is fixed at the prime rate on the date the loan was initiated.

If a participant's employment with the Company terminates and the loan balance is not paid in full by the termination date, the participant may make manual payments directly to the Trustee to avoid default. Loans will be subject to default if a payment has not been made for a period of time as outlined by the Plan document or if the participant takes a distribution of their account balance.

Payment of Benefits

In-service distributions are allowed for certain cases of financial hardship, upon the participant's attainment of age 59-1/2 or if the participant is still employed after age 73.

Upon termination of employment, participants may elect to roll over account balances into another qualified retirement vehicle, receive a lump-sum or partial lump-sum distribution, or receive installment payments. Terminated participants with balances exceeding $1,000 may elect to remain in the Plan and defer payment until such time the participant attains age 73 and becomes subject to required minimum distributions. Account balances less than $1,000 are distributed as soon as administratively possible following termination of employment.

December 31, 2025 and 2024

Administrative Expenses

Administrative expenses of the Plan may be paid either by the Plan or the Company, as provided in the Plan document. Expenses paid by the Company are excluded from these financial statements. Certain fees are charged directly to participant accounts and are included in administrative expenses in the accompanying statement of changes in net assets available for benefits. Investment expenses are included in net appreciation of the fair value of investments.

Transfers to and from Other Plans

Transfers of assets between plans generally occur if a change in the employment status of an employee, who participates in a Company-sponsored plan, causes the employee to change plans due to eligibility requirements. During the year ended December 31, 2025, $1,164,144 was transferred from the Plan into the Brunswick Rewards Plan, while $3,870 was transferred into the Plan from the Brunswick Rewards Plan.

Plan Termination

Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event that the Plan is terminated, the Benefits Administration Committee can direct that all accounts be distributed to its participants or continued in trust for their benefit. Participants will also become 100% vested at this time.

2. Significant Accounting Policies

Basis of Accounting

The accompanying financial statements of the Plan have been prepared under the accrual basis of accounting.

Payment of Benefits

Benefits are recorded when paid.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Investment Valuation and Income Recognition

Investments held by the Plan are stated at 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 (an exit price). See Note 4 - Fair Value Measurements for further discussion of fair value measurements.

The Brunswick ESOP Company Stock Fund is a fund composed principally of Brunswick Corporation common stock. Dividends received on shares held in the Brunswick ESOP Company Stock Fund may be reinvested in the Plan or, if elected by the participant, received as cash.

Purchases and sales of investments are recorded on a trade-date basis. Interest income is accrued when earned. Dividend income is recorded on the ex-dividend date. Capital gain distributions are included in dividend income. Net appreciation includes plan gains and losses on investments bought and sold as well as held during the year.

Brunswick Retirement Savings Plan

Notes to Financial Statements

December 31, 2025 and 2024

Notes Receivable from Participants

Notes receivable from participants represent participant loans that are recorded at their unpaid principal balance plus any accrued but unpaid interest. Interest income on notes receivable from participants is recorded when it is earned. Related fees are recorded as administrative expenses and are expensed when they are incurred. If a participant ceases to make loan repayments and the Plan administrator deems the participant loan to be a distribution, the participant loan balance is reduced and a benefit payment is recorded.

Recent Accounting Pronouncements

The Company evaluates the pronouncements of various authoritative accounting organizations, primarily the Financial Accounting Standards Board ("FASB"), the Securities and Exchange Commission ("SEC"), and the Emerging Issues Task Force ("EITF"), to determine the impact of new pronouncements on U.S. GAAP and the impact on the Plan. There were no material impacts to the Plan in 2025, or that are expected to impact the Plan in the future.

3. Interest in Brunswick Corporation Master Trust

The Master Trust agreement includes Separately Managed Accounts (SMAs) which hold certain investment assets of both the Plan and the Brunswick Rewards Plan. An SMA is an investment account composed of individually selected securities—such as stocks, mutual funds, and collective trusts, which are all selected and managed by the designated investment manager per the mandate of their fund. Certain investment options offered to participants are structured as SMAs and are held within the Master Trust. Each participating plan has a divided interest in the Master Trust. Plan investments and investment income reported in the Plan’s financial statements include the Plan’s interest in the Master Trust's net assets and investment gains and losses.

The net assets in the Master Trust and the Plan's interest in the Master Trust as of December 31, 2025 and December 31, 2024 are as follows:

4. Fair Value Measurements

Fair value is defined as the exchange price that would be received for 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 on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. There is a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable.

Level 1 - Quoted prices in active markets for identical assets or liabilities. These are typically obtained from real-time quotes for transactions in active exchange markets involving identical assets or liabilities.

Level 2 - Inputs, other than quoted prices included within Level 1, which are observable for the asset or liability, either directly or indirectly. These are typically obtained from readily available pricing sources for comparable instruments.

Level 3 - Unobservable inputs for which there is little or no market activity for the asset or liability. These inputs reflect the reporting entity's own assumptions of the data that market participants would use in pricing the asset or liability, based on the best information available in the circumstances.

The level in the fair value hierarchy within which the fair value measurement is classified is determined based on the lowest level of input that is significant to the fair value measurement in its entirety.

The following is a description of the valuation techniques and inputs used for assets measured at fair value:

Common stock: Valued at the quoted market price of shares held by the Plan at year-end.

Target date retirement collective trust funds: The fair values of investments in target date retirement collective trusts are valued as determined by fund managers based on their net asset values ("NAV") and recent transaction prices. There are target date collective trust funds ranging from 2020 through 2070, in five-year increments, and an income fund. The asset allocation of each target date retirement collective trust fund (except for the income fund) gradually changes over time according to a targeted retirement year until the fund merges with the income fund. The trusts invest in mutual funds at varying asset allocations as appropriate to adjust to a more conservative mix over time as participants approach their target retirement age. Each collective trust provides for daily redemptions by the Plan at reported net asset values per share, with no advance notification requirement. There are no unfunded commitments associated with these funds.

Mutual funds: Valued at quoted market prices.

Stable value collective trust: The fair value of investments in the stable value retirement savings collective trust are valued as determined by fund managers based on their NAV. This fund invests largely in investment contracts backed by high-quality, shorter-term securities. There are no restrictions on participant redemptions of the stable value retirement savings collective trust. There are no unfunded commitments associated with this fund. The fund is subject to a 12‑month withdrawal restriction for employer‑initiated events, including plan termination or transfers to competing investment options.

Brunswick Retirement Savings Plan

Notes to Financial Statements

December 31, 2025 and 2024

Collective trusts: The fair values of participation units held in the collective trust fund are based on the net asset values per unit as reported by the fund managers. The collective trust fund provides for daily redemptions by the participants at reported net asset values per share, with no advance notice requirement. There are no unfunded commitments associated with this fund.

Net assets available for benefits per the financial statements	$	178,219,524	$	162,530,168

Net assets per Form 5500	$	178,214,585	$	162,525,231

6. Risks and Uncertainties

The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market, liquidity, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the fair value of certain investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the Statements of Net Assets Available for Benefits.

7. Related Party and Party-In-Interest Transactions

Parties-in-interest are defined under Department of Labor regulations as any fiduciary of the Plan, any party rendering service to the Plan, the employer, and certain others. The Plan holds units of mutual funds managed by The Vanguard Group, Inc. The Vanguard Group, Inc. is an affiliate of Vanguard Fiduciary Trust Company, the Plan Trustee; therefore, these transactions and the Plan's payment of trustee fees to Vanguard qualify as party-in-interest transactions. The Plan also holds units of the Vanguard mutual funds and collective funds which are issued by Vanguard Fiduciary Trust Company or an affiliate thereof. The Plan also holds shares of Brunswick Corporation common stock. These shares appreciated in fair value by $1,127,416 and recognized dividend income of $181,788 during 2025. At December 31, 2025 and 2024, the Plan held 101,930 and 100,061 shares of Brunswick Corporation common stock. Notes receivable from participants also reflect party-in-interest transactions. Certain administrative functions are performed by officers or employees of the Company. No such officer or employee receives compensation from the Plan.

Notes to Financial Statements

December 31, 2025 and 2024

8. Income Tax Status

The IRS has determined and informed the Company by a letter dated July 27, 2017 that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code ("IRC"). Although the Plan has been amended since receiving the determination letter, Plan management believes that the Plan is designed and being operated in compliance with the applicable requirements of the IRC. Therefore, Plan management believes that the Plan was qualified and the related trust was tax-exempt as of the financial statement date.

U.S. GAAP requires the management of the Plan to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by applicable taxing authorities. Management of the Plan has analyzed tax positions taken by the Plan and has concluded that, as of December 31, 2025 and December 31, 2024, there were 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.

9. Subsequent Events

The Plan evaluated subsequent events through June 25, 2026, the date the financial statements were issued, and no events were identified requiring adjustment to or disclosure in the financial statements.

Brunswick Rewards Plan

Notes to Financial Statements

December 31, 2025 and 2024

1. Description of the Plan

The following description of the Brunswick Rewards Plan (the "Plan") provides only general information. Brunswick Corporation (the "Company" or "Employer") is the Plan's sponsor. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.

General

The Plan, established by the Company effective April 1, 1999, is a defined-contribution plan subject to the requirements of the Employee Retirement Income Security Act of 1974 ("ERISA"), as amended. Any related company, as defined in the Plan, may, with the Company’s consent, adopt the Plan. The Plan is administered by the Benefits Administration Committee, consisting of at least three members appointed for indefinite terms by the Company’s Board of Directors. Certain of the investment assets of the Plan are held in the Brunswick Corporation Master Trust (the "Master Trust") at Vanguard Fiduciary Trust Company (the "Trustee"). Vanguard Fiduciary Trust Company is the Trustee of the Plan for all investment assets under an agreement with the Company.

Participation

Eligible employees include all groups under the terms of the Plan.

Eligible employees under the terms of the Plan, who are not eligible to participate in the Brunswick Retirement Savings Plan, a separate plan sponsored by the Company, must be at least 18 years of age and employed by the Company or a related company to which the Plan has been extended. Employees are immediately eligible to participate in the Plan and are automatically enrolled in the Plan at a deferral rate of 3% of eligible compensation. Employees have a window of 60 days from the date their demographic data is received at the Trustee in which to opt out of the Plan before automatic enrollment. Employees can generally increase, decrease, or cancel their deferrals at any time.

Participant Accounts

Each participant’s account is credited with the participant’s contributions and allocations of: (a) the Company’s contributions, (b) the Plan’s earnings (losses), and (c) charged with an allocation of administrative expenses and, where applicable, specific transaction-based fees to participants who incur such transactions. Allocations are based on participant earnings or account balances as defined in the Plan. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s account balances.

Contributions

Brunswick Rewards Plan

Notes to Financial Statements

December 31, 2025 and 2024

The Company may make an annual retirement profit sharing contribution of up to 9% of compensation as defined by the Plan to the accounts of participants employed by the Company as of December 31 of the current plan year. The Company may also make an annual retirement profit sharing contribution to participants that were terminated during the plan year due to death, disability, layoffs, or retirement. Retirement profit sharing contributions are invested in accordance with the participant’s investment elections. As of December 31, 2025 and 2024, retirement profit sharing contributions of $20,814,244 and $3,352,527, respectively, are included as Employer contributions receivable (net of forfeitures) in the accompanying Statements of Net Assets Available for Benefits.

The Plan provides a true-up feature, which allows the Company to make up for any missed match resulting from the difference between the per payroll calculation performed throughout the year and the annualized amount due under the terms of the Plan. The true-up is performed during the first quarter of the following plan year and takes into account the maximum matching contribution that could have been received and makes up for any difference in comparison to the matching contributions that were actually made. True-ups of certain participant accounts were $665,366 and $954,374 for the years ended December 31, 2025 and 2024, respectively. These amounts are included as Employer contributions receivable (net of forfeitures) in the accompanying Statements of Net Assets Available for Benefits.

Forfeited balances of participants' nonvested accounts are used to reduce future Company contributions or to pay administrative expenses incurred by the Plan. At December 31, 2025 and 2024, forfeited nonvested accounts totaled $1,101,371 and $2,351,688, respectively. All of the forfeited nonvested accounts at December 31, 2024 were used to reduce employer contributions or pay Plan administrative expenses during 2025.

Vesting

Participants are required to complete two years of service to become fully vested in employer matching contributions and employer retirement profit sharing contributions.

Notes Receivable from Participants

Payment of Benefits

In-service distributions are allowed for certain cases of financial hardship, upon the participant's attainment of age 59-1/2 or if the participant is still employed after age 73.

Administrative Expenses

Transfers to and from Other Plans

Transfers of assets generally occur if a change in the employment status of an employee, who participates in a Brunswick-sponsored plan, causes the employee to change plans due to eligibility requirements. During the year ended December 31, 2025, $3,870 was transferred from the Plan into the Brunswick Retirement Savings Plan, while $1,164,144 was transferred into the Plan from the Brunswick Retirement Savings Plan.

3. Interest in Brunswick Corporation Master Trust

The Master Trust agreement includes Separately Managed Accounts (SMAs) which hold certain investment assets of both the Plan and the Brunswick Retirement Savings Plan. An SMA is an investment account composed of individually selected securities—such as stocks, mutual funds, and collective trusts, which are all selected and managed by the designated investment manager per the mandate of their fund. Certain investment options offered to participants are structured as SMAs and are held within the Master Trust. Each participating plan has a divided interest in the Master Trust. Plan investments and investment income reported in the Plan’s financial statements include the Plan’s interest in the Master Trust's net assets and investment gains and losses.

The net assets in the Master Trust and the Plan's interest in the Master Trust as of December 31, 2025 and December 31, 2024 are as follows:

6. Risks and Uncertainties

7. Related Party and Party-In-Interest Transactions

Parties-in-interest are defined under Department of Labor regulations as any fiduciary of the Plan, any party rendering service to the Plan, the employer, and certain others. The Plan holds units of mutual funds managed by The Vanguard Group, Inc. The Vanguard Group, Inc. is an affiliate of Vanguard Fiduciary Trust Company, the Plan Trustee; therefore, these transactions and the Plan's payment of trustee fees to Vanguard qualify as party-in-interest transactions. The Plan also holds units of the Vanguard mutual funds and collective funds which are issued by Vanguard Fiduciary Trust Company or an affiliate thereof. The Plan also holds shares of Brunswick Corporation common stock. These shares appreciated in fair value by $4,720,237 and recognized dividend income of $813,790 during 2025. At December 31, 2025 and 2024, the Plan held 436,128 and 422,468 shares of Brunswick Corporation common stock. Notes receivable from participants also reflect party-in-interest transactions. Certain administrative functions are performed by officers or employees of the Company. No such officer or employee receives compensation from the Plan.

December 31, 2025 and 2024

8. Income Tax Status

The IRS has determined and informed the Company by a letter dated August 24, 2017 that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code ("IRC"). Although the Plan has been amended since receiving the determination letter, Plan management believes that the Plan is designed and being operated in compliance with the applicable requirements of the IRC. Therefore, Plan management believes that the Plan was qualified and the related trust was tax-exempt as of the financial statement date.
