### Dear Fellow Shareholders,
Thank you for your continued confidence and support. The past year brought its share of economic uncertainty, yet 2025 proved to be another strong year for our company. Improving loan growth, disciplined risk management, and thoughtful deposit pricing helped us remain on track. Growth in our deposit base came from delivering an exceptional banking experience—one built on trust, service, and relationships—not from competing on the highest rates. In addition, the strength of our balance sheet allowed us to take advantage of securities repositioning opportunities that improved our net interest margin and contributed meaningfully to core profitability. Asset quality improved throughout the year, and careful expense management allowed us to continue investing in the talent and technology that position us well for long-term success.

Looking ahead to 2026, the path forward appears promising. Economic conditions across our markets remain generally healthy, and the ongoing improvement in credit quality reinforces the strength of our lending practices. A strong loan pipeline, supported by healthy demand, gives us confidence in our ability to continue to improve loan growth in the coming year. We expect to build on our enviable deposit base as we deepen existing client relationships and cultivate new ones.

The momentum built in 2025 sets the stage for further progress in 2026. Continued net interest margin expansion, balance sheet growth, and increasing profitability enhance our capacity to invest strategically in both people and initiatives that drive the future of our franchise. These efforts aim to create lasting value for you—our shareholders—while ensuring we remain a trusted financial partner in our communities.

Thank you for your ongoing trust and support. We remain committed to prudent decision making, operational discipline, and creating sustainable value for all shareholders.

Sincerely,

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) During 2025, each member serving on the Bancorp Board and the Company's Bank Board, who is not also an officer or employee of the Company received an aggregate director fee of $94,100; paid approximately $47,050 in Company stock and approximately $47,050 in cash. Compensation for service for incumbent directors is paid semi-annually in arrears in July and January. The stock-based compensation to each director was paid in Company common stock with a market value at the time of grant, with fractional shares being paid in cash. The Chairs of the Bank's Wealth Management and Trust Services Committee and the Company's Compensation Committee and Nominating and Governance Committee received an additional annual cash payment of $6,200. The Chairs of the Audit Committee and the Bank's Asset/Liability Committee received an additional annual cash payment of $7,800. The Board approved an additional annual cash payment of $26,300 to the Chairman of the Board. The Compensation Committee has reviewed the additional cash payments paid to the Chairman of the Board and the committee chairs relative to the Company's peer group, discussed further in the Compensation Discussion and Analysis. Upon this review, the Compensation Committee affirmed the annual cash payments for these services. The stock portion of the fees awarded were from the 2020 Director Stock Plan approved by shareholders at the 2020 Annual Meeting. If a director retires from the Board before earned director compensation is paid, that individual receives payment in cash rather than in stock. A Director Deferred Fee Plan, which allows members of the Board of Directors to defer the cash portion of their director compensation, went into effect on January 1, 2021, and the first deferral of their fees was in July 2021.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Mr. Kennedy elected to defer $27,368 of his cash compensation, and Mr. Hale elected to defer $49,277 of his cash compensation.

&nbsp;&nbsp;&nbsp;&nbsp;(3) As of December 31, 2025, from previous non-qualified stock option awards, Mr. Hale had 29,395 exercisable shares and Mr. Kennedy had 16,286 exercisable shares. Mr. Colombo had 64,323 exercisable shares from awards granted during his employment with the Company.

&nbsp;&nbsp;&nbsp;&nbsp;(4) Mr. McDevitt and Mr. Sanghvi retired from the Board in May 2025.

Corporate Governance

#### Indebtedness and Other Transactions with Directors and Executive Officers
In accordance with the Nominating and Governance Committee Charter, the Nominating and Governance Committee is responsible for reviewing and acting upon all related party transactions required to be disclosed by Item 404 of Regulation S-K for potential conflicts of interest. Additionally, the Company's Code of Ethical Conduct provides rules that restrict transactions with affiliated persons.

Prior to engaging in any related party transaction, a completed questionnaire describing the nature and structure of the transaction, along with any necessary supporting documentation, is submitted to the Nominating and Governance Committee. In determining whether to approve a related party transaction, the Nominating and Governance Committee will consider, among other things, the following:

● Whether the terms of the transaction are fair to the Company;

● Whether the transaction is material to the Company;

● The importance of the related person to the transaction;

● The role the related person has played in arranging the transaction;

● The structure of the transaction; and,

● The interests of all related persons in the transaction.

The Company will only enter into a related party transaction if the Nominating and Governance Committee determines that any interested director has abstained from voting on the matter and that the transaction is beneficial to the Company, and the terms of the transaction are fair to the Company.

The Company is not currently engaged in any related party transactions.

The Company's subsidiary, Bank of Marin, has had and expects to have banking transactions in the ordinary course of business with some of the directors and executive officers of the Bank (and their associates), on substantially the same terms (including interest rates, collateral and repayment terms) as those prevailing at the time for comparable loans with persons not related to the Company. During 2025 no loan to any director or executive officer of the Company (or their associates) has involved more than normal risk of collectability or presented other unfavorable features. All loans to directors or executive officers would be subject to the limitations prescribed by California Financial Code Section 1360, et seq. and applicable federal law and regulations.

#### Board Leadership Structure
It is the role of the Nominating and Governance Committee to annually review, and when appropriate make recommendations to the Board of Directors concerning board composition, structure, and functions. The Board has deemed it appropriate to have two separate individuals serve as Chairman of the Board and Chief Executive Officer. According to the Company's bylaws, the Chairman of the Board shall preside at meetings of the Board of Directors and shareholders and exercise and perform such other powers and duties as may be from time to time assigned to him/her by the Board of Directors. The bylaws further provide that the President of the Company shall, subject to the control of the Board of Directors, have general supervision, direction, and control of the business and the officers of the Company. As the oversight responsibilities of the Board of Directors grows, the Board believes it is beneficial to have an independent Chairman with the sole job of leading the Board, while allowing the President to focus his efforts on the day-to-day management of the Company and the Bank. The Board does believe that it is important to have the President as a director. The Company aims to foster an appropriate level of separation between these two distinct levels of leadership of the Company. In addition to the Chairman, leadership is also provided through the respective chairs of the Board's various committees.

Corporate Governance

#### Board's Role in Risk Oversight
It is a fundamental part of the Board's responsibility to understand the risks the Company faces and what steps management is taking to manage those risks. It is also important that the Board understands what level of risk is appropriate for the Company. The Board fulfills its oversight responsibility with respect to compliance and operational risk, by working with the Company's Compliance Manager to understand regulatory and legislative issues and the Company's projects and systems. While the Board of Directors has the ultimate oversight responsibility for the risk management process, various committees of the Board also have responsibility for risk management. In particular, the Audit Committee focuses on risk assessment and risk management as they relate to financial reporting, including appropriate guidelines and policies to govern the process, as well as the Company's major financial reporting risks and the steps management has taken to monitor and control them, and the Committee receives an annual risk assessment report from the Company's independent auditor In setting compensation, the Compensation Committee strives to create incentives that do not encourage excessive risk-taking beyond the Company's ability to effectively identify and manage risk. The Bank's Asse/Liability Committee functions as a directors' loan committee, oversees the Bank's balance sheet, liquidity and capital management, as well as the management of credit, interest rate, and market risk within the context of the risk tolerance established by the Board of Directors, and receives monthly reports from the Chief Credit Officer and Chief Financial Officer. Additionally, on a quarterly basis, the Board of Directors and various committees (Compensation Committee, the Bank's Wealth Management and Trust Services Committee and the Bank's Asset Liability Management Committee) receive and review reports from the Company's consolidated enterprise risk management program. In general, that program is designed to ensure the adequacy of policies, procedures, tolerance levels, risk measurement systems, monitoring processes, management information systems and internal controls. Board and committee review of quarterly reporting is an important component of the overall enterprise risk management system. The Board of Directors is also provided physical and information security risk assessments by management on an annual basis.

#### Insider Trading Policies and Procedures
The Company has adopted an insider trading policy (the "Insider Trading Policy") that applies to all (i) directors, (ii) executive officers, and (iii) employees who are exposed to insider information (together, the "Covered Persons"). The Insider Trading Policy prohibits the use of material non-public information obtained by Covered Persons through their involvement with the Company when making decisions to purchase, sell, give away, or otherwise trade in the Company's securities or to provide such information to others outside the organization. Further, we have established black-out periods to which all Covered Persons are subject, including quarterly black-out periods which commence fourteen (14) days before the end of the quarter and continue until the close of the second trading day after quarterly earnings results are disclosed on Form 8-K. The Company may impose black-out periods from time to time as other types of material non-public information occur or when material non-public events or disclosures are pending. If the Company imposes a special black-out period, the Company will notify Covered Persons accordingly.

#### Stock Option Grant Timing Policy
The Company has not granted stock options since 2022. Accordingly, the Company has not adopted policies and practices on the timing of awards of stock options in relation to the disclosure of material non-public information of the Company, as contemplated by Item 402(x)(2) of Regulation S-K.

Executive Compensation

#### Compensation Discussion and Analysis
This section addresses the compensation programs, philosophy and objectives, of Bank of Marin Bancorp and its banking subsidiary, Bank of Marin (collectively in this section, the "Company"), including the process for making compensation decisions, the roles of the Board of Directors, the Compensation Committee (in this section, the "Committee"), and management in the design of such programs, and its 2025 executive compensation components. This section also addresses the factors most relevant to understanding the Company's compensation programs and what they are designed to reward, including the essential elements of compensation, the reasons for determining payment of each element of compensation, and how each compensation element fits into the Company's overall compensation objectives and affects decisions regarding other compensation elements.

Executive Summary

The Committee of the Board of Directors establishes and administers the compensation and benefit programs for Named Executive Officers, the persons identified in the Summary Compensation Table which follows. In addition, the Committee is responsible for administering other company-wide compensation and benefits plans for all employees. The Committee consists entirely of independent directors. The Committee carefully considers the components of the executive compensation programs to attract and retain high quality Named Executive Officers and to incent the behavior of Named Executive Officers to create shareholder value and accomplish the Company's strategic goals. The Committee engages independent consultants from time to time and considers the compensation programs of peer financial institutions to ensure that the Company's compensation programs are competitive with market practices.

The Committee's philosophy, practices and policies have been developed over a number of years and have not historically been subject to sweeping, material changes. At the 2025 annual meeting of shareholders, the Company included an advisory vote to approve executive compensation, providing shareholders with an opportunity to communicate their views on the Company's executive compensation program. The Company's executive compensation was approved by approximately 80% of the shares voted. The Committee considered the results of this vote in setting executive compensation for 2026 and concluded that the support of the Company's compensation program indicates that shareholders generally concur with the Company's alignment of compensation and performance. At the 2023 Annual Meeting of Shareholders, the shareholders held, by majority vote, for a one-year frequency of the non-binding, advisory vote on executive compensation. While the frequency vote was non-binding, the Board of Directors has made the decision to continue to include the advisory vote to approve executive compensation annually.

Shareholder outreach and feedback is a critical component of our investor relations philosophy, and, in 2025, we continued to maintain a regular dialogue with our shareholders. Throughout the year, we engaged in conversations and meetings, including sell-side conferences, non-deal road shows and in-person or telephonic one-on-one meetings with our shareholder base.

Philosophy

The Company's executive compensation programs are designed to attract and retain high quality officers that are critical to its long-term success. The Company's Board of Directors and management believe that the most effective executive compensation program is one that is designed to reward the achievement of specific annual, long-term and strategic goals, which aligns Named Executive Officers' interests with those of the shareholders by rewarding performance above established goals, with the ultimate goal of improving shareholder value without rewarding undue short-term risk-taking. This is achieved by utilizing a combination of short-term cash incentives, paid annually, and long-term equity incentives, which vest over a three-year period and include performance-based vesting metrics. The Committee engages independent national human resources consulting firms to periodically conduct a review of the Company's total compensation programs. During these periodic reviews, each component of total compensation is compared against a peer group that is similar to the Company in asset size, geography and performance. (For details, see "Compensation Consultants" and "Peer Group Review" herein.) In 2025, the Committee adopted a new peer group to be used in 2025. The 2025 peer group was made up generally of major exchange publicly traded banks in the Western states, including Hawaii, with total assets between $2 billion and $10 billion.

26 Bank of Marin Bancorp 2026 Proxy Statement

[**Table of Contents**](#TOC)

Executive Compensation

The Committee's compensation philosophy is to target base salaries at or near the median (50<sup>th</sup> percentile) and to pay total compensation (including annual cash incentives, long-term equity incentives, and benefits) at the 50<sup>th</sup> percentile of the regional peer group, with variation based on individual experience and individual and Company performance. The Company believes paying total compensation between the 50<sup>th</sup> and 75<sup>th</sup> percentile for above-average performance is critical for attracting and retaining the qualified executives it needs to achieve its business objectives. Overall, compensation paid to Company executives is believed to be competitive with market practices.

Base compensation levels for Named Executive Officers are established based on market data and are adjusted based on individual performance and experience. Annual incentives, including performance-based bonuses and long-term equity awards, are based on both Company and/or individual performance objectives, which include asset and revenue growth targets, deposit growth targets, profitability targets, credit quality metrics, identification and execution of strategic opportunities, and core earnings performance. It is the Committee's desire to remove as much discretion as possible from the incentive-based compensation in favor of a metrics-based program.

Business Highlights

Results for 2025 were significantly impacted by the Company's strategic balance sheet repositioning which included the sale of available-for-sale ("AFS") securities with a book value of $185.8 million, resulting in a pre-tax loss of $18.7 million in the second quarter of 2025, the sale of AFS securities of $593.2 million in low yielding investment securities at a $69.5 million pre-tax loss in the fourth quarter of 2025, the purchase and origination of higher yielding loans and securities and the replenishment of capital ratios through the issuance of $45.0 million of subordinated debt. The Company continues to proactively identify and manage credit risk within the loan portfolio, reflected in the percentage of non-accrual loans which decreased from the prior year, and improvements in credit quality trends during the fourth quarter. The Company believes the strength of the balance sheet, higher level of loan origination productivity that is being seen from banking teams, and positive trends in net interest margin and operating leverage are key factors that should help mitigate any unforeseen credit quality deterioration that may arise and drive further improvement in financial performance in the year ahead.

On a non-GAAP basis, excluding the losses on sale of securities noted above, net income was $9.4 million for the fourth quarter, a 25% increase over the third quarter, and diluted earnings per share was $0.59, a 26% increase compared to the prior quarter. Non-GAAP net income for the year was $26.5 million, compared to net income of $14.5 million in the prior year, an 82% increase. Securities loss-adjusted metrics including pre-tax pre-provision net income, net income, and return on assets improved during 2025.

Process for Making Compensation Decisions

*Role of the Chief Executive Officer* 

Shortly following the conclusion of each calendar year, the Company's Chief Executive Officer (the "CEO"), assisted by the Director of Human Resources, conducts an annual performance evaluation process for all Named Executive Officers, other than for himself, as well as for other members of senior management who are not Named Executive Officers. As part of each annual performance evaluation, the CEO considers, among other key factors, i) the executive's performance of job responsibilities and achievement of individual and/or departmental objectives and ii) management and leadership skills, such as effective communication, problem solving, business development and community involvement. In addition, the executive's contributions to the Company's overall financial goals are indirectly considered. Based on this evaluation, the CEO determines, for each of the Named Executive Officers (other than himself), recommendations for salary adjustments, including merit increases, and annual performance-based bonus amounts to be made to the Committee for its approval. The Named Executive Officer's performance-based bonus is determined by the Company's financial performance relative to that year's financial performance goals and individual performance goals.

Executive Compensation

In addition, recommendations by the CEO and the Director of Human Resources for the grant of equity awards to Named Executive Officers under the Company's equity compensation plan are submitted to the Committee for approval and are based on Named Executives Incentive Equity opportunity and the Company's financial performance relative to that year's financial performance goals.

*Role of the Compensation Committee* 

The Committee periodically reviews the compensation levels of the Board of Directors. In its review, the Committee looks to ensure that the compensation is fair, reasonably competitive and commensurate to the responsibilities of both the individual directors as well as the Board in the aggregate. Additionally, the Committee specifically takes into consideration the Directors' adherence to the Company's Director Stock Ownership Guidelines when reviewing compensation.

The Committee has responsibility for establishing, implementing and continually monitoring adherence with the Company's compensation philosophy. The Committee ensures that the total compensation paid to Named Executive Officers is fair, reasonable and competitive and that the types of compensation and benefits provided to the Named Executive Officers are similar to comparable executives within an established peer group. The Committee is also responsible for the review and approval of Company goals and objectives relevant to the compensation, including the incentive awards, of the Company's CEO, to evaluate the performance of the CEO in light of the goals and objectives and to determine and approve the CEO's compensation levels based on this evaluation. The Committee reviews compensation levels for the other Named Executive Officers, including the CEO's recommendations on annual bonus and salary increases for Named Executive Officers and makes final determinations and approvals. Additionally, the Committee reviews and approves the grant of equity awards to assure that the Committee considers all elements of proposed compensation.

To achieve these goals and objectives, the Committee expects to maintain compensation plans that create an executive compensation program that is set at competitive levels of comparable public financial services institutions with comparable performance. The Committee has followed certain fundamental objectives to ensure the effectiveness of the Company's compensation strategy. These objectives include the following:

*Internal and external fairness*. The Committee recognizes the importance of perceived fairness both internally and externally of compensation practices. The Committee has evaluated the overall economic impact of the Company's compensation practices and, when deemed necessary, has consulted with independent outside advisors in the evaluation of contractual obligations and compensation levels.

*Performance-based incentives*. The Company has established financial incentives for executives who meet certain objectives, which thereby assist the Company in meeting its long-term growth and financial goals.

*Shareholder value and long-term incentives*. The Committee believes that the long-term success of the Company and its ability to consistently increase shareholder value is dependent on its ability to attract and retain skilled executives. The Company's compensation strategy encourages equity-based compensation to align the interests of management and shareholders.

*Full disclosure*. The Committee seeks to provide full disclosure to the members of the Board of Directors of the Company of the compensation practices and issues to ensure that all directors understand the implications of the Committee's decisions.

The Committee has reviewed the compensation practices of peers and considered management's individual efforts for the benefit of the Company and has reviewed various subjective measures in determining the adequacy and appropriateness of the compensation of Named Executive Officers. The Committee takes into account the performance of the Named Executive Officers and recognizes that the competition among financial institutions for attracting and retaining executives has become more intense in the past few years. The Committee takes such market considerations into account to ensure that the Company is providing appropriate long-term equity incentives to enable it to continue to attract new executives and to retain the ones it already employs. General economic conditions and the past practice of the Company are also factors that are considered by the Committee. Further, the Committee specifically takes into consideration:

● Double-trigger Change in Control Severance Payments

[**Table of Contents**](#TOC)

Executive Compensation

● Absence of any gross-ups in any of the incentive programs

● Clawback Policy covering our performance-based incentive plan

● Executive Stock Ownership Guidelines

The Committee has established various processes to assist in ensuring that the Company's compensation program is achieving its objectives. Among these are:

*Assessment of Company Performance*. In establishing total compensation ranges, the Committee uses company performance measures, including net income, asset growth, earnings per share, return on assets, asset quality, and efficiency ratio in two ways: to gauge generally the overall Company performance relative to peer companies and to gauge generally the overall Company performance against the Company's own strategic objectives. These specific performance targets provide guidance for a view of general Company performance, which is then utilized as one element in determining overall compensation ranges.

*Assessment of Individual Performance*. Individual performance has a strong impact on the compensation of all employees, including the CEO and the other Named Executive Officers. For the Named Executive Officers, the Committee receives a performance assessment and compensation recommendation from the CEO, other than for himself, and also exercises its judgment based on the Board's interactions with its Named Executive Officers. As with the CEO, the performance evaluation of these Named Executive Officers is based on his or her contribution to the Company's performance, and other leadership accomplishments.

*Total Compensation Review*. The Committee reviews each Named Executive Officer's base pay, bonus, and equity award compensation annually. In addition to these primary compensation elements, the Committee reviews the perquisites and other compensation and payments that would be required under various severance and change-in-control scenarios. Following the 2025 review, the Committee determined that these elements of compensation were reasonable in the aggregate.

Compensation Consultants

Pearl Meyer & Partners ("Pearl Meyer"), a large independent compensation consulting firm, has been engaged by the Committee as its independent advisor on compensation matters. After the Committee's review of applicable rules for independence, the Committee determined that there are no known conflicts of interest between Pearl Meyer and its affiliates and the Company and its affiliates. Pearl Meyer reports directly to the Committee and does not provide services to, or on behalf of, any other part of the Company's business.

The major services provided by Pearl Meyer include: 1) review of the Company's then current peer group, 2) recommendations to the Committee to refine the peer group based on the Company's and peers' size, 3) comprehensive review of the Company's executive compensation programs, 4) comprehensive review of the Company's non-employee director compensation program, and 5) review of the Company's 2025 target total direct compensation levels provided to the Company's Named Executive Officers and non-employee directors, as well as the Company's financial performance relative to the selected peer group to make recommendations to the Committee. The analysis and review performed by Pearl Meyer in 2025 were used in 2025 in setting executive compensation programs.

During 2025, Pearl Meyer provided minor, additional consulting activities, including reviewing the Company's performance relative to peers, incentive metrics and executive retirement plan options.

Peer Group Review and Market Study

When reviewing each compensation component for the Named Executive Officers, the Committee considers the compensation practices of specific peer companies whose asset size, geography and performance are comparable to the Company. In 2025, the Committee adopted an updated peer group to be used for informing compensation decisions in 2025. The 2025 peer group was established by prioritizing Western U.S.-based commercial banks that are publicly traded, and similar to BMRC in size – particularly in assets ($1.8B - $10B), revenue, and market capitalization, as of November 7, 2024. Additional emphasis is placed on comparable business models, including loan mix, number of offices, and employees.

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Heritage Commerce Corporation  | ● TriCo Bancshares |

---

The median assets at 2025 fiscal year end for the peer group was $3.93 billion as compared to Bank of Marin's $3.90 billion. Comparisons to the Peer Banks in this discussion are based on the 2025 Peer Banks.

The Committee evaluated executive compensation to like positions in the 2025 Peer Banks in setting 2025 compensation. Based on this evaluation and Pearl Meyer's analysis of the Company's compensation programs relative to the peer group, the Committee approved the following executive compensation structure:

● Target executive base compensation near the 50 <sup>th</sup> percentile of the peer group, as established in 2025, which reflects a minor de-emphasis on base compensation with more focus on incentive opportunity.

● Maximum incentive opportunity in 2025 was placed at 200% of the target incentive for both short term and long-term performance incentives and 50% for threshold performance.

Executive Compensation Components

For the fiscal year ended December 31, 2025, the principal components of compensation for Named Executive Officers were i) base salary, ii) performance-based bonuses, iii) equity awards and iv) perquisites and other plans and benefits. The Company's policies and practices for each of the principal compensation components are explained in the following paragraphs.

*Base Salary*

Base salary is established based on market data and is adjusted based on individual performance and experience.

*Performance-Based Incentives*

The Company provides annual cash incentive award opportunities for eligible employees, through the use of the Annual Individual Incentive Compensation Plan (the "Incentive Plan"). The Incentive Plan allows for performance-based bonuses for Named Executive Officers that are based on the overall performance of the Company and on goals specific to the executive's area of responsibility. The following table shows the bonus potential expressed as a percentage of base salary that may be earned in the Incentive Plan under three scenarios: Threshold Performance, Target Performance and Maximum Performance, and then shows the relative split between Bankwide performance goals versus individual performance metrics by Named Executive Officer that must be met under the Incentive Plan.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Effective January 2, 2025, David Bonaccorso assumed the role of Chief Financial Officer.

Overall Company performance comprises at least 75% of the CEO's and at least 50% of the other Named Executive Officers' cash incentive potential, with the remaining percentage based on achievement of individual goals.

Based on the annual operating plan, the Committee approved five Bankwide metrics for each of the NEOs and each NEO was given a specific weighting for the five goals. The Committee approved the use of Core Return on Assets, Annual Loan Growth, Annual Deposit Growth, Core Pre-tax, Pre-provision Net Income, and Core Non-Interest Expense. The plan also provides that for the Incentive Plan to be funded and "activated" for a Plan Year, the Company must achieve a threshold performance level calculated as a percentage of the Company's budgeted net income.

Individual Named Executive Officer goals are either independent from the five Company metrics or may be used to give greater weighting to one of the five Company goals within the executive's specific area of responsibility. The allocation between company goals and individual goals varies from year to year. For 2025 the weights of each metric as a percent of the total incentive compensation opportunity for the Named Executive Officers were:

---

|:---|:---|:---|:---|:---|:---|
| **Company Metrics** | **Myers** | **Bonaccorso** | **Bloom** | **Campbell** | **Stewart** |
| Core Pre-tax Pre-provision Net Income | 22.50% | 15.00% | 15.00% | 15.00% | 15.00% |
| Core Return on Assets | 15.00% | 10.00% | 10.00% | 10.00% | 10.00% |
| Core Non-Interest Expense | 7.50% | 5.00% | 5.00% | 5.00% | 5.00% |
| Annual Loan Growth | 15.00% | 10.00% | 10.00% | 10.00% | 10.00% |
| Annual Deposit Growth | 15.00% | 10.00% | 10.00% | 10.00% | 10.00% |

---

The Committee also approved specific individual metrics which were either one of the five core metrics used to give greater weighting to one of the five Company goals within the executive's specific area of responsibility, or independent from the five Company metrics.

The specific corporate goal for 2025 included the following:

---

In addition to the bonuses earned from the plan by each NEO, the Committee awarded a discretionary bonus to Ms. Stewart for exceptional work that was not fully reflected in the performance metrics. Specifically, Ms. Stewart directly impacted the overall improvement of the underlying credit risk in the bank's loan portfolio, particularly with the portfolio of non-performing assets.

After determining the payouts under the annual incentive, including the discretionary amounts, the average total payout for the NEOs was 112.32% of the target annual incentive awards.

*Clawback Policy for Performance-Based Incentives*

The Clawback Policy, consistent with Nasdaq and SEC requirements, provides that if financial results are significantly restated due to negligence, fraud or intentional misconduct, there will be recoupment of the amounts paid in excess of amounts otherwise earned.

*Recovery of Erroneously Awarded Compensation*

On February 24, 2026, the Company filed a Form 8-K disclosing an accounting misclassification related to a specific type of reciprocal network deposit account resulting in a restatement of financial statements for 2024 and 2023. This resulted in a reclassification of certain deposits from non-interest bearing to interest bearing deposits. Additionally, the related expense was included in deposit network fees within non-interest expense instead of interest expense but had no impact on net income or earnings per share.

In accordance with SEC rules and Nasdaq listing standards, the Clawback Policy applies to incentive-based compensation received on or after October 2, 2023. Any incentive-based compensation received prior to that date is not subject to recovery under the Clawback Policy. The Company performed an analysis of (i) the impact of the revision to the financial statements for 2023 and 2024 on incentive-based compensation received by its officers covered by the Clawback Policy related to such years year, which officers included Timothy D. Myers, Brandi Campbell, Tani Girton, Nicolette Sloan, and Misako Stewart (collectively, the "Covered Officers"), and (ii) whether recovery of any incentive-based compensation related to such years was required under the Clawback Policy.

Based on the Company's review of incentive-based compensation received by the Covered Officers on or after October 2, 2023, the Company determined that the deposit reclassification resulted in no change in awarded performance-based compensation, and therefore no clawback was required for either of the affected fiscal years. Of the performance metrics utilized for determining incentive-based compensation for 2023 and 2024, the only three that were potentially impacted by the revision to the financial statements were, Net Interest Margin ("NIM"), efficiency ratio and non-interest expense. However, the payout threshold for the affected metrics generally was not met for those years, and no incentive compensation was paid to the Covered Officers for such metrics. In the two instances where a payout was earned, the metric was improved and would have triggered a larger incentive payment. Given these results the Company determined that no clawback was required.

*Equity Awards*

The purposes of equity awards are to allow executives to share in the growth and prosperity of the Company, to retain executives over the long term and to maintain competitive levels of total compensation.

For 2025, the Committee determined to grant a blend of 50% performance-based restricted stock (Performance Shares) and 50% time-vested restricted stock (Restricted Shares) for NEOs other than the CEO. For the CEO the split was 62.5% performance-based restricted stock (Performance Shares) and 37.5% time-vested restricted stock (Restricted Shares). This reflects the Committee's commitment to focusing on pay for

For the 2025 performance equity award, metrics are based on a comparison of relative performance to peers, based on the ending percentile ranking of the Company and absolute metrics based on bank performance. For 2025, the relative to peers measure required at median performance to earn the target number of shares. Achievement at maximum performance results in 200% of target shares earned for each metric after application of the metric weighting, and achievement at threshold performance results in 50% of target shares earned for each metric.

*Perquisites and Other Plans and Benefits*

Consistent with the Company's compensation objectives, Named Executive Officers are provided perquisites and other benefits that management believes are reasonable and consistent with the Company's overall compensation program and which keep the Company competitive in the marketplace. The Company periodically reviews the level of perquisites and other benefits provided to the Named Executive Officers for suitability with the program objectives.

The Company is competitive with market practices by providing medical, dental, vision and life insurance, a 401(k) employer matching contribution up to $5,000 annually, and an Employee Stock Purchase Plan (the "ESPP"). The Company also offers key management, including the Named Executive Officers, a monthly auto allowance that is based on position and his/her contact with clients.

Executive Compensation

Employee Stock Ownership Plan

The Company also provides an Employee Stock Ownership Plan (the "ESOP"). Annually, the Company may make discretionary contributions of shares of common stock to the ESOP. The decision normally is based on the Company's financial performance and condition. The purposes of the ESOP are to include all eligible employees in the ownership of the Company, to provide them with compensation that is free from current income tax and to accumulate benefits for retirement. Stock is awarded as a percentage of eligible cash compensation. Executives receive the same percentage as all other employees, up to the IRS limits.

Deferred Compensation Plan

The Company sponsors an unsecured, non-qualified plan known as the Deferred Compensation Plan, which allows Named Executive Officers and certain other highly compensated employees to defer all or a portion of their base salary and/or bonus. Balances in the plan receive earnings, all of which are described in the "Nonqualified Deferred Compensation" table of this Proxy Statement. Other than earnings accruals, all credits to the Deferred Compensation Plan represent a Named Executive Officer's compensation previously earned and deferred; the Company does not provide any matching or similar credits. The plan was designed to allow Named Executive Officers to defer some of their current income to help them with tax planning, and to assist the Company in attracting and retaining top executives by providing retirement benefits that are competitive within the Company's peer group.

Supplemental Executive Retirement Plan

The Company also sponsors the Bank of Marin Supplemental Executive Retirement Plan. This plan allows named executives with the title of Executive Vice President and above who contribute materially to the continued growth, development and future business success of the Company, to receive a supplemental income at retirement. As this type of plan is commonly offered among the Company's peers, the inclusion of this benefit enhances the Company's compensation program allowing the Company to recruit, retain and reward key decision makers of the Company. See "Supplemental Retirement Plan for Named Executive Officers" herein for more information on this plan.

Change in Control Agreements

The Company provides Named Executive Officers and other senior officers with agreements that provide for certain specified benefits upon a change in control of the Company. These agreements are very useful tools that help the Company retain its key employees, including the Named Executive Officers, by providing those executives some certainty in compensation in the event the Company were to be sold, and also helps to ensure that the Company will have the benefit of their services through the pendency of any merger. Such agreements are particularly necessary in an industry such as ours, where there has been considerable consolidation over the last ten years. See "Potential Payments upon Termination or Change in Control" herein for detailed information about these agreements, including a description of payout amounts under a hypothetical change in control of the Company as of the last business day of 2025.

Compensation Risk Assessment

In determining the level of risk arising from the Company's compensation policies and practices, a thorough review and risk assessment evaluation of the Company's compensation plans for all employees, as well as the overall compensation philosophy was conducted. The Committee evaluated the form and mix of compensation, controls and process, and the Company's business strategies. The Committee has concluded that the Company's compensation arrangements do not encourage employees to take unnecessary and excessive risks.

&nbsp;&nbsp;&nbsp;&nbsp;(1) The "Other" column includes perquisites and personal benefits, such as car allowances, provided to the Named Executive Officers. Each of the above Named Executive Officers received less than $11,000 of aggregate perquisites and personal benefits, except Mr. Myers who received an auto allowance of $14,400. The "Other" column also includes special bonuses, matching contributions to the 401(k) Plan, profit sharing contributions to the Employee Stock Ownership Plan, imputed income on life insurance paid by the Company, imputed income on long term care insurance paid by the Company, dividends paid on unvested restricted stock, interest paid on the Deferred Compensation Plan and the prorated account value increase attributable to the Supplemental Executive Retirement Plan. Of those, Mr. Myers received $5,000 of matching 401(k) contributions, $18,392.98 of profit-sharing contributions to the Employee Stock Ownership Plan, $70,682.25 of unvested restricted stock dividends, and $94,671 of the pro-rated account value increase attributable to the Supplemental Executive Retirement Plan. Mr. Bonaccorso received $5,000 of matching 401(k) contributions, $18,392.98 of profit-sharing contributions to the Employee Stock Ownership Plan, $8,539.50 of unvested restricted stock dividends, and $59,593 of the pro-rated account value increase attributable to the Supplemental Executive Retirement Plan.

#### CEO Pay Ratio
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we have calculated the pay ratio between Chief Executive Officer ("CEO"), Timothy D. Myers, and the median annual total compensation of our employees. The Company believes that the ratio of pay included in this information is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K.

As of December 31, 2025:

The median annual total compensation of all employees of our company (other than the CEO) was $117,806; and the annual total compensation of our CEO was $1,961,189, including non-discriminatory benefits.

Based on this information, for 2025 the ratio of the annual total compensation for our CEO to the median of the annual total compensation of our employees was 17 to 1.

Methodology

This pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and the methodology described below. The SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices. Therefore, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

38 Bank of Marin Bancorp 2026 Proxy Statement

[**Table of Contents**](#TOC)

Executive Compensation

Median Employee Identification and Compensation Calculation

For purposes of determining the compensation paid to the employees under consideration, we used earnings subject to Medicare tax as reported in Box 5, ''Medicare wages and tips'' on each employee's 2025 Form W 2. This group includes full-time, part-time and temporary workers. We did annualize the compensation of anyone who was employed by us for only part of the year.

SEC rules permit determination of the median employee once every three years. The median employee was determined in 2025. December 31, 2025 was the date selected to identify the "median employee" because our employee base does not materially change at any point during the year.

Once we identified our median employee, we identified and calculated the elements of such employee's compensation for 2025 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K. The median employee's total compensation for 2025 consisted of the following elements: base wages plus overtime, an annual cash incentive earned in 2025 and paid in February 2026, change in pension SERP value, contributions to the Employee Stock Ownership Plan and matching contributions into the 401(k) plan. We also include the value of any non-discriminatory benefit plans in the total compensation amount.

CEO Compensation Calculation

We then calculated our CEO's annual total compensation using the same approach to determine the pay ratio shown above.

As stated earlier in this discussion, we believe compensation must be competitive to attract and retain essential talent, to reward high performance, and to be internally equitable. Our expected total compensation opportunities for our employees are specific to the role they hold at the Company and generally reflect market median pay levels for our broader base of employees and median pay levels of our peer group for our executives, with variations based on specific talent needs, experience, and other internal factors. We believe that actual total compensation should vary with the performance of the organization, such that outstanding performance results in above-market compensation.

The tax reform legislation passed in December 2017, generally referred to as The Tax Cuts and Jobs Act, substantially modifies Section 162(m) and, among other things, eliminates the "performance based" exception to the $1 million deduction limit with respect to taxable years beginning after December 31, 2017. Effective for the fiscal year beginning January 1, 2018, compensation paid to our Named Executive Officers (including our Chief Financial Officer), will be subject to the limitations on deductibility under Section 162(m), and we will not be able to deduct performance based compensation to our Named Executive Officers (including our Chief Financial Officer) who receive annual compensation in excess of $1 million.

We invest in our employees at all levels in the Company by rewarding performance that balances risk and reward, empowering professional growth and development, and by offering affordable benefits and programs that meet the diverse needs of our employees and their families.

Executive Compensation

The Bank of Marin 1999 Stock Option Plan (the "1999 Plan") was adopted by the Board of Directors and approved by the Bank's shareholders in 1999, and subsequently adopted by the Company in 2007 through its holding company reorganization. The 1999 Plan was replaced by the 2007 Equity Plan (the "2007 Plan"), which was adopted by the Board of Directors and approved by the shareholders in 2007. No options have been granted from the 1999 Plan since April 2007. In 2017, the Board of Directors adopted and shareholders approved the 2017 Equity Plan (the "2017 Plan"), which replaced the 2007 Plan. No options have been granted from the 2007 Plan since March 2017. No options have been granted from the 2017 Plan since March 2022.

&nbsp;&nbsp;&nbsp;&nbsp;(1) The stock option awards granted from 2015 through 2022 vest by approximately 33% on each anniversary of the grant date for three years.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The time-based restricted stock awards granted from 2015 through 2025 vest by approximately 33% on each anniversary of the grant date for three years. The performance-based restricted stock awards added in 2015 are granted at two times the target and are contingent upon the achievement of pre-established long-term performance goals. Performance is measured over a three-year period and cliff vested. Further discussion regarding restricted stock awards can be found in the Equity Awards section in the Compensation Discussion and Analysis of this proxy statement.

&nbsp;&nbsp;&nbsp;&nbsp;(3) The market value of the restricted stock awards that have not vested was determined by multiplying the closing market price of the Company's Common stock on December 31, 2025 ($26.01) by the number of restricted shares.

#### Supplemental Executive Retirement Plan
The Company has established a Supplemental Executive Retirement Plan (the "SERP" or the "Plan") covering officers in business lines of the Company with the title of Executive Vice President and above. The SERP is an unsecured non-qualified defined benefit plan that is unfunded and has no plan assets. Under the Plan, the participant's benefit payment is valued at 25% of his or her final salary. Most participants will be required to participate in the Plan for five years before vesting begins and after five years, the participant will vest ratably in the benefit over the remaining period until age 65. The payout duration for eligible employees will be a minimum of five years and a maximum of fifteen years and each benefit contract is set up to provide one year of benefit payout per year of participation in the plan subject to the minimum and maximum durations.

See "Potential Payments upon Termination or Change of Control" herein for a description of the events that will result in payout of the benefit payment and the terms for each event under this Plan.

The following table shows the present value of the accumulated benefit payable to each of the Named Executive Officers that participate in the SERP as of December 31, 2025:

Executive Compensation

#### Nonqualified Deferred Compensation for 2025
The Nonqualified Deferred Compensation Plan is intended for a select group of employees of the Company who are in the highest salary band. Employees can defer up to 80% of their base salary and up to 100% of bonus compensation into the plan. These are considered irrevocable elections and stay in place for the entire calendar year. The Company does not make any employer contributions to this plan, and employees are always 100% vested in their contributions. Named Executive Officers also make an election for distributions from the plan at termination.

The following table sets forth the plan contributions and earnings during 2025 and the aggregate balances at December 31, 2025:

#### Potential Payments upon Termination or Change in Control
Set forth below is a description of the plans and agreements that could result in potential payments to Named Executive Officers in the case of their termination of employment and/or a change in control.

Employment Agreement and Termination without Cause

Mr. Myers' employment agreement provides that upon a termination of his employment without cause, as severance he will be paid twelve months' salary in effect at the date of termination, an amount equal to his pro rata bonus earned up to the date of the termination, plus eighteen months' COBRA payments for health premiums and dental/vision premiums. Assuming Mr. Myers was terminated without cause on December 31, 2025, his estimated severance payment would have been $1,444,551.

Change in Control Agreements

Each Named Executive Officer has signed a Change in Control Agreement. The circumstances that would trigger payment(s) or the provision of other benefits, including perquisites and health care benefits under the Change in Control Agreement are: i) a Change in Control (defined in accordance with Section 409A of the Internal Revenue Code) followed by, ii) the occurrence within one year after the Change in Control of either termination of employment or a subsequent "Good Reason," including:

Without the executive's express written consent, an adverse change in executive's position or title, the assignment to the executive of any duties or responsibilities inconsistent with the executive's position or removal of the executive from or any failure to re-elect the executive to any of such positions;

● A reduction of the executive's base salary;

● A 20% or greater reduction in non-salary benefits;

● Failure of the Company to obtain the assumption of the Change in Control Agreement by any successor; or

● Requirement by the Company that the executive be based anywhere other than within 40 miles of the Company's current headquarters located in Novato, California.

Stock Options and Restricted Stock Awards

In the event of a change in control in which the Company is not the surviving corporation, unvested options and restricted stock awards immediately vest.

Executive Compensation

Supplemental Executive Retirement Plan

A participant whose employment terminates due to a change in control will be vested in 100% of the amount that the Company has accrued to that point to pay their retirement benefit. This accrued benefit will be paid out in a one-time payment.

Other Payments and Benefits

The Company shall pay to the executive as severance pay (and without regard to the provisions of any benefit plan) in a lump sum on the fifth day following the date of termination, the average salary of the executive for the last three full years of service multiplied by the executive's Seniority Factor (CEO 1.50 times; EVP 1.50 times), the executive's annual bonus for the previous year, and the executive's health premiums under COBRA for eighteen months and Dental/Vision premiums under COBRA for twelve months. All Change in Control Agreements contain a clause that limits payments to an executive to the lesser of (i) the payment provided for in the agreement, or (ii) the largest payment allowable without the imposition of an excise tax due to an "excess parachute payment" under Internal Revenue Code section 280(g). Such clauses are commonly referred to as "280(g) cutback" clauses.

Estimated Total Benefit*s*

The table below quantifies the estimated payments and benefits that would be provided to our Named Executive Officers in connection with the termination of his or her employment under the provisions of the Change in Control Agreements.

In all cases, the information assumes that the triggering event occurred on the last day of fiscal year 2025, and the price per share of the Company's common stock is the closing market price as of that date (which was $26.01).

Executive Compensation

Retirement

Unvested options and restricted stock awards will be cancelled, unless it is a qualifying retirement and the relevant award was made after 2017. In the event of a qualifying retirement for an award made after 2017, unvested options fully vest and all restrictions on restricted stock awards will lapse. Vested options may be exercised within ninety days of separation, unless it is a qualifying retirement and the relevant award was made after 2019. In the event of a qualifying retirement for an award made after 2019, vested options may be exercised at any time before the expiration date of the award. Deferred compensation account balances will be distributed six months after separation, following the executive's distribution elections. The executive whose employment terminates after the normal retirement age of sixty-five will receive 100% of his or her supplemental retirement benefit, payable monthly. The annual benefit payment will be equal to 25% of his or her final salary and will be distributed subject to the minimum and maximum durations noted above.

Disability

Unvested options fully vest and all restrictions on restricted stock awards will lapse. Vested options shall remain exercisable upon the earlier of (a) expiration of the twelve-month period commencing with the date of such cessation of employment status or (b) the expiration date of the option term. Deferred compensation account balances will be distributed six months after separation, following the executive's distribution elections. The executive will receive 100% of the supplemental retirement benefit that the Company has accrued to that point. Payments will begin immediately and will be paid monthly for the same duration as the normal retirement benefit was to be paid.

Death

Unvested options fully vest and all restrictions on restricted stock awards will lapse in the event of death of an award recipient. Vested options shall remain exercisable until the earlier of (a) expiration of the twelve-month period measured from the date of the executive's death or (b) the expiration date of the option term. Deferred compensation account balances will be distributed six months after the executive's death, following the executive's distribution elections. Benefits of 1.5 times the executive's salary (at the time of death) will be payable to the beneficiary of record. If the executive is employed by the Company at the time of his or her death, the beneficiary of the executive will be paid the value of the executive's projected supplemental retirement account balance at the normal retirement age. The balance will be paid to the beneficiary in a one-time payment. The Company has an appropriate amount of life insurance in force on the life of each participant to properly fund for this contingency.

The Compensation Committee Sets the Terms and Conditions for Equity Awards

The Compensation Committee or the Board, as the case may be, may accelerate (i) the date on which any option award may be exercised or (ii) the date of termination of the restrictions applicable to a restricted stock award, if the Committee or the Board, as appropriate, determines that to do so will be in the best interests of the Company and the participants in the plan.

#### Employment Contracts
There are currently no employment contracts between the Company or the Bank and their executive officers except the Company and the Bank have an employment agreement with Timothy D. Myers, their President and Chief Executive Officer. The agreement was for an initial two-year term commencing on November 1, 2021, but renews annually on November 1st of each year unless a party gives written notice to the other within certain time periods. The agreement established a base salary of $475,000 and allows for an increase annually. For 2025, Mr. Myers' annual base salary was $693,250. While the agreement provides the potential to earn an annual incentive payment of up to sixty-five percent (65%), of the executive's salary, the Compensation Committee has approved the potential to earn an annual incentive payment of up to 100% of the executive's salary. The agreement also provides participation in the Company's reimbursement policy and participation in the Company's benefit plans that are available to senior executives and employees generally. Additionally, the agreement provides for payment of an automobile allowance of $1,200 per month, and reimbursement for necessary air travel expenses for Mr. Myers' spouse up to a maximum of $2,000 per year. If the agreement were terminated without cause, Mr. Myers would receive severance pay equal to one year's annual base salary

Executive Compensation

in effect at the date of termination, an amount equal to his pro rata bonus earned up to the date of the termination, plus six months' COBRA payments for health premiums and eighteen months' COBRA payments for dental/vision premiums.

#### Employee Stock Ownership Plan and 401(k) Plan
An employee becomes a participant in the 401(k) Plan as of the first day of the quarter following the date on which he/she attains age eighteen and has completed three months of employment. A participant may elect to defer a portion of his/her salary, not to exceed limitations set by the IRS, into the plan. Distributions from the 401(k) Plan are not permitted before age 59 1/2 except in the event of death, disability, termination of employment or IRS permitted hardships. As determined by the Board of Directors, the Company may make discretionary matching contributions to the 401(k) Plan. In 2025 and 2024 the Company made matching contributions of $957 thousand and $951 thousand, respectively.

An employee becomes a participant in the Employee Stock Ownership Plan ("ESOP") as of the first day of the quarter following the date on which he/she attains age eighteen and has completed three months of employment. A participant will have a non-forfeitable right to 100% of his/her ESOP account balance upon disability or upon his/her normal retirement date or completion of at least five years of service, whichever is later. Distributions from the plan are not permitted before age 59 1/2 except in the event of death, disability, termination of employment or IRS permitted diversification. The Company's contributions of $1,587 thousand in 2025 and $1,237 thousand in 2024 were used to purchase shares of Company stock for the ESOP.

#### Incentive Bonus Plan
Bank of Marin has incentive bonus programs for the Bank's executive officers, and for the non-executive officers and staff pursuant to the Bank of Marin Individual Incentive Plan (discussed elsewhere herein). Contributions by the Bank to both programs are based upon the Bank's achievement of specified levels of financial performance as determined by the Board of Directors. In 2025 the Bank expensed $4,800 thousand for these programs and bonus payments were made in the first quarter of 2026.

| &nbsp;&nbsp;**Proposal Number 2**<br>**Advisory Vote to Approve Executive Compensation**<br>The Company seeks a non-binding advisory vote from shareholders to approve the compensation of the Named Executive Officers, as described in detail under the Executive Compensation section of this proxy statement. | &nbsp;&nbsp;✓ The Board recommends a vote **FOR** this proposal |

---

In 2025, the Company included an advisory vote to approve executive compensation, providing shareholders with an opportunity to communicate their views on the Company's executive compensation program. The Company's executive compensation was approved by approximately 80% of the shares voted. The Committee considered the results of this vote in setting executive compensation for 2026 and concluded that the strong support of the Company's compensation program indicates that shareholders generally concur with the Company's alignment of compensation and performance. At the 2023 Annual Meeting of Shareholders the shareholders held, by majority vote, for a one-year frequency of the non-binding, advisory vote on executive compensation. While the frequency vote was non-binding, the Board of Directors has made the decision to include the advisory vote to approve executive compensation annually.

As discussed in the Compensation Discussion and Analysis, the Company's Board of Directors and management believe that the most effective executive compensation program is one that is designed to reward the achievement of specific annual, long-term and strategic goals. The Company believes that this philosophy aligns the interests of executive officers with those of the shareholders by rewarding performance above established goals.

The Company's compensation programs are designed to attract and retain high quality executive officers that are critical to long-term success. There are four components to the compensation of Named Executive Officers:

Base salary, which is established based on market data and adjusted on individual performance and experience.

Performance-based incentives, which are based on the overall performance of the Company and on individual goals specific to the executive's area of responsibility.

Equity incentives, which allow the executives to share in the growth and prosperity of the Company.

Perquisites and other benefits that management believes are reasonable and consistent with the Company's overall compensation program and will keep the Company competitive in the marketplace.

This proposal gives you as a shareholder of the Company the opportunity to make a non-binding advisory basis vote on the Company's overall executive compensation of the Named Executive Officers as disclosed in this proxy statement. Accordingly, you may vote on the following resolution:

**"RESOLVED, that the shareholders approve the compensation of the Company's Named Executive Officers as disclosed in this proxy statement pursuant to the compensation disclosure rules of the Securities and Exchange Commission (which includes the Compensation Discussion and Analysis, the compensation tables and related narrative discussion)."**

The Board of Directors and the Compensation Committee value the opinions of shareholders and will take into account the outcome of the vote when considering future executive compensation arrangements.

**THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE APPROVAL, ON AN ADVISORY BASIS, OF THE EXECUTIVE OFFICER COMPENSATION AS DESCRIBED IN THE COMPENSATION DISCUSSION AND ANALYSIS AND THE ACCOMPANYING COMPENSATION TABLES CONTAINED IN THE PROXY STATEMENT.**

| &nbsp;&nbsp;**Proposal Number 3**<br>**Independent Auditor**<br>Appointment of Independent Auditor | &nbsp;&nbsp;✓ The Board recommends a vote **FOR** this proposal |

---

Baker Tilly US ("Baker Tilly") is currently serving as the Company's independent registered public accounting firm. The Audit Committee of the Board of Directors selected Baker Tilly to perform audit services for the Company and its subsidiary, Bank of Marin, for the year ending December 31, 2026. This selection has been approved by unanimous resolution of the Board of Directors.

In accordance with our long-standing tradition, the shareholders are hereby asked to ratify the Audit Committee's recommendation of the Company's independent auditor, Baker Tilly. The approval of a majority of the shares represented at the Annual Meeting is required to ratify the selection of Baker Tilly. A Baker Tilly representative will be available to answer questions at the Annual Meeting and will have an opportunity to make a statement if they desire to do so.

Baker Tilly has served as the Company's independent auditor since 2004, formerly under the name Moss Adams LLP, as they were acquired and merged in 2025. There are no affiliations between the Company and Baker Tilly, its partners, associates or employees other than those which pertain to the engagement of Baker Tilly in the previous year as independent auditor for the Company and for certain permitted consulting services.

The audit reports on the financial statements of Bank of Marin Bancorp and subsidiary as of and for the fiscal years ended December 31, 2025 and 2024 were issued by Baker Tilly and Moss Adams (now Baker Tilly), respectively, and did not contain an adverse opinion or disclaimer of opinion, nor were the reports qualified or modified as to uncertainty, audit scope, or accounting principles.

The Audit Committee carefully considers the qualifications of the audit firm's lead partner when approving his or her appointment to serve a five-year rotation with the Company. Baker Tilly has appointed Gabe Nachand to lead the audit engagement with the Company.

#### Independent Auditor Fees
Fees incurred for professional services provided by Moss Adams for 2025 and 2024 are shown in the following table.

---

| | | |
|:---|:---|:---|
| **($ in thousands)** | **2025** | **2024** |
| Audit Fees<sup>(1)(2)</sup> | $790000 | $739000 |
| All Other Fees | $— | $— |
| Total Fees | $790000 | $739000 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) Audit Fees are the aggregate fees billed for professional services in the fiscal year 2025 and 2024 by Baker Tilly (formerly Moss Adams) for the audit of the annual financial statements, review of the quarterly financial statements and work related to compliance with the Sarbanes-Oxley Act of 2002

&nbsp;&nbsp;&nbsp;&nbsp;(2) 2025 fees include amounts paid and estimated fees expected to be billed for the audit of the Company's 2025 financial statements. 2024 fees reflect actual fees related to the 2024 audit.

The Audit Committee discussed these fees and services with the independent auditor and Company management and determined that they are permitted under the rules and regulations concerning auditor independence promulgated by the SEC to implement the Sarbanes-Oxley Act of 2002, Nasdaq and the American Institute of Certified Public Accountant.

Proposal Number 3: Independent Auditor

#### Pre-Approval of Independent Auditor Fees and Services
It is the policy of the Audit Committee that all engagements for audit, audit-related, tax, and other non- audit services provided by the independent auditor be pre-approved by the Audit Committee and cannot commence until such approval has been granted. The pre-approval includes a review of the services to be undertaken, consideration of potential for conflicts of interest, and the estimated fees. The services performed by Baker Tilly for the 2025 audit engagement were pre-approved by the Audit Committee, in accordance with the Audit Committee's procedures. In granting pre-approval requests for non-audit services, the Audit Committee considers whether the provision of non-audit services by Baker Tilly is compatible with maintaining auditor independence.

Requests for pre-approval are discussed at regularly scheduled Audit Committee meetings. The authority to grant specific pre-approval between meetings, as necessary, has been delegated to the Chair of the Audit Committee. The Chair must inform the Committee at the next regularly scheduled meeting of any services that were granted specific pre-approval.

### AUDIT COMMITTEE REPORT
The Audit Committee (the "Committee") of the Board of Directors (the "Board") oversees the accounting and financial reporting processes of the Company, the audits of the Company's financial statements, the qualifications of the public accounting firm engaged as the Company's independent auditor and the performance of the Company's internal and independent auditors. The Committee's function is more fully described in the Board approved Audit Committee charter, available through the Company's investor relations website at www.bankofmarin.com. The charter specifies the scope of the Committee's responsibilities and the framework within which it carries out those responsibilities. The Committee reviews its charter every year, and any proposed changes are reviewed and approved by the full Board.

The Committee consists of no fewer than three (3) members of the Board, each of whom is independent under the Nasdaq listing standards, SEC rules and other regulations applicable to audit committees.

The Company's Board has determined that all Committee members satisfy the financial literacy requirements in the Nasdaq listing standards and that the Committee has at least one "audit committee financial expert" as defined by the SEC rules. However, Committee members are not professional accountants or auditors, are not experts under the Securities Act of 1933 in these fields, and their functions are not intended to duplicate or to certify the activities of management and the independent audit firm. Members of the Committee are expected to participate in continuing education relating to the duties and requirements of audit committees. The Committee serves a Board-level oversight role in which it provides advice, counsel, and direction to management and to the auditors.

The Committee assembles information from a range of sources, including discussions with management, independent auditors, internal audit personnel, and the experience of the Committee's members in business, financial, and accounting matters.

The Committee meets as needed but at least quarterly. There were eight (8) meetings in 2025 (four general meetings and four meetings to review financial report filings). The Committee schedules its meetings with a view to ensuring that it devotes appropriate attention to all of its tasks. These meetings include, whenever appropriate, executive sessions in which the Committee meets separately with the independent auditors, internal audit personnel and management to determine if there are any concerns regarding the Company's accounting or financial practices.

The Committee has the authority to engage its own outside advisors, including experts in particular areas of accounting, as it determines appropriate. These advisors are apart from counsel or advisors hired by management. The Company's Internal Audit department reports directly to the Committee and is responsible for objectively reviewing and evaluating the adequacy, effectiveness, and quality of the Company's system of internal controls related to the reliability and integrity of its financial information and the safeguarding of its assets. In 2025 Baker Tilly, the Company's independent registered public accounting firm, was responsible for performing an independent audit of the Company's consolidated financial statements in accordance with generally accepted auditing standards and expressing an opinion on the effectiveness of the Company's internal controls over financial reporting.

Baker Tilly has provided the Committee with the written disclosures and management letter required by the Public Company Accounting Oversight Board ("PCAOB") regarding the independent accountant's communications with the Committee concerning independence, and the Committee has discussed with the audit firm and management the information provided regarding that independence. During this process nothing came to the attention of the Committee which suggested that Baker Tilly is not independent; however, the Committee is not required (and does not certify) that the independent audit firm is independent under applicable rules.

The Committee meets with the independent auditor, Bank of Marin management and the Internal Audit Manager to review interim financial results before publication of quarterly earnings results. Discussions cover topics and events that may have a significant financial impact. The Committee also reviews and discusses with management steps taken to identify, monitor and control significant financial reporting risks.

[**Table of Contents**](#TOC)

Audit Committee Report

In accordance with law, the Committee has ultimate authority and responsibility for selecting, compensating, evaluating, and, when appropriate, replacing the Company's independent audit firm. Although the Committee has the sole authority to appoint the independent audit firm, the Committee will continue its longstanding practice of recommending that the Board ask the shareholders to ratify the appointment of the independent accountants at the Annual Meeting.

The Committee annually reviews the independent Auditor performance. In conducting these reviews, the Committee considers, among other factors:

● Historical and recent performance of the audit, including the extent and quality of its communications with the Committee

● Data relating to audit quality and performance, including recent PCAOB reports

● The appropriateness of proposed fees, both on an absolute basis and as compared with its peer firms

● Tenure as the Company's independent auditor and its depth of understanding of the Company's business, accounting policies and practices, including the potential effect on the financial statements of the major risks facing the Company and internal control over financial reporting

● The independent auditor's professional skepticism and objectivity, including perspectives brought through periodic required rotation of the lead audit partner, quality review partner and other engagement team partners, and

● The advisability and potential impact of selecting a different independent public accounting firm

The Committee agenda for a given year includes reviewing Bank of Marin's interim financial results, earnings and financial statements, internal controls over financial reporting, and all audit-related activities, including approval of the annual audit schedule, auditor reports and management responses to findings. The Committee reviews and discusses with management and the independent auditor the Company's major financial reporting risks and the steps that management has taken to monitor and control such risks. The Committee also reviews and approves the engagement and funding for supplementary internal auditing services.

The Committee is responsible for establishing and monitoring procedures for the receipt, retention and disposition of complaints received by the Bank regarding accounting, financial reporting, internal accounting and financial controls, and auditing concerns (also known as the "Alert Line" policy and procedures). This responsibility includes ensuring that there is a means for the confidential submission by employees of the Company, or of third parties that provide services to the Company, of any concerns regarding potentially questionable accounting or auditing matters. The Committee is committed to ensuring that these submissions can be made anonymously while meeting all regulatory requirements**.**

The Committee has reviewed and discussed with management its assessment and report on the effectiveness of the Company's internal controls over financial reporting as of December 31, 2025. The Committee also has reviewed and discussed with Baker Tilly its review and report on the Company's internal control over financial reporting.

The Committee has reviewed and discussed the audited financial statements for fiscal year 2025 with management and Baker Tilly. Management represented to the Committee that the Company's audited financial statements were prepared in accordance with U.S. generally accepted accounting principles, and Baker Tilly represented that its presentations to the Committee included the matters required to be discussed with the independent registered public accounting firm by applicable PCAOB rules regarding "Communication with Audit Committees." This review included a discussion with management of the quality and acceptability of the Company's accounting principles, the reasonableness of significant estimates and judgments, and the clarity of disclosure in the Company's financial statements, including the disclosures related to critical accounting estimates.

**QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING**

#### General Proxy Statement Information
Bank of Marin Bancorp, a corporation existing and organized under the laws of the State of California, is authorized to issue up to 30,000,000 shares of common stock and 5,000,000 shares of preferred stock. All of the outstanding shares are voting common shares and are entitled to vote at the Annual Meeting. Only those common shareholders of record as of April 8, 2026 (the "Record Date") will be entitled to notice of, and to vote at, the meeting. On that date,16,189,707 shares of common stock were outstanding. The determination of shareholders entitled to vote at the meeting and the number of votes to which they are entitled was made on the basis of the Company's records as of the Record Date. The presence in person or by proxy (including internet and telephone voting) of a majority of the outstanding shares of stock entitled to vote at the Annual Meeting will constitute a quorum for the purpose of transacting business at the meeting. Abstentions, shares as to which voting authority has been withheld from any nominee and "broker non-votes" (as defined below), will be counted for purposes of determining the presence or absence of a quorum.

A broker or nominee holding shares for beneficial owners may vote on certain matters at the meeting pursuant to discretionary authority or instructions from the beneficial owners, but with respect to other matters for which the broker or nominee may not have received instructions from the beneficial owners and may not have discretionary voting power under the applicable rule of the New York Stock Exchange or other self-regulatory organizations to which the broker or nominee is a member, the shares held by the broker or nominee may not be voted. Such un-voted shares are called "broker non-votes." The rules of the New York Stock Exchange and other self-regulatory organizations generally permit a broker or nominee, in the absence of instructions, to deliver a proxy to vote for routine items, such as the ratification of independent auditors. Consequently, shares held by a broker or nominee will constitute "broker non-votes" regarding non-routine items, such as the election of directors and the advisory vote on executive compensation.

If your shares of common stock are held in a brokerage account or by a bank, trustee or other nominee (i.e., your shares are held in "street name"), you will receive a Voting Instruction Form from that nominee. You must provide voting instructions by completing the Voting Instruction Form and returning it to your broker, bank, trustee or other nominee for your shares to be voted. We recommend that you instruct your broker, bank, trustee or other nominee to vote your shares on the Voting Instruction Form provided. The proxy is revocable and will not affect your right to vote in person if you attend the 2026 Annual Meeting.

Anyone acting as proxy agent for a shareholder must present a proxy card that has been properly executed by the shareholder, which authorizes the agent to so act, and that is in form and substance satisfactory to the Inspector of Election and consistent with the Bylaws.

#### Revocability of Proxies
A proxy for use at the meeting is enclosed. Any shareholder who executes and delivers such proxy has the right to revoke it at any time before it is exercised by filing with the Corporate Secretary of the Company an instrument revoking it or by filing a duly executed proxy bearing a later date. In addition, the powers of the proxy holder will be revoked if the person executing the proxy is present at the meeting, revokes such proxy and elects to vote in person. Subject to such revocation, all shares represented by a properly executed proxy received in time for the meeting will be voted by the proxy holders in accordance with the instructions on the proxy.

**IF NO INSTRUCTION IS SPECIFIED WITH REGARD TO A MATTER TO BE ACTED UPON, THE SHARES REPRESENTED BY THE PROXY WILL BE VOTED IN ACCORDANCE WITH THE RECOMMENDATIONS OF THE BOARD OF DIRECTORS "FOR" THE ELECTION OF ALL NOMINEES FOR DIRECTOR LISTED HEREIN, "FOR" THE APPROVAL OF THE COMPANY'S EXECUTIVE COMPENSATION, AND "FOR" RATIFICATION OF THE SELECTION OF INDEPENDENT AUDITOR.**

Questions and Answers

#### Person Making the Solicitation
This solicitation of proxies is being made by the Board of Directors of the Company. The expense of preparing, assembling, printing, and mailing this proxy statement and the material used in the solicitation of proxies for the meeting will be borne by the Company. It is contemplated that proxies will be solicited principally through the use of the mail, but officers, directors, and employees of the Company and Bank of Marin may solicit proxies personally or by telephone, without receiving special compensation therefor. Although there is no formal agreement to do so, the Company may reimburse banks, brokerage houses, and other custodians, nominees, and fiduciaries for their reasonable expense in forwarding these proxy materials to their principals.

#### Voting Rights
In connection with the election of directors, in accordance with California law, each shareholder entitled to vote may vote the shares owned by such shareholder as of the Record Date cumulatively if a shareholder present at the meeting has given notice at the meeting, prior to the voting, of his or her intention to vote cumulatively. If any shareholder has given such notice, then all shareholders entitled to vote for the election of directors may cumulate their votes for candidates properly nominated. Under cumulative voting, each share carries as many votes as the number of directors to be elected, and the shareholder may cast all of such votes for a single nominee or may distribute them in any manner among as many nominees as desired. Shares represented by proxies that are marked with instructions to "withhold authority" for the election of one or more director nominees or that are not voted (whether by abstention, broker non-vote or otherwise) will not be counted in determining the number of votes cast for those persons. In the election of directors, the ten nominees receiving the highest number of votes will be elected.

On all other matters submitted to the vote of the shareholders, each shareholder is entitled to one vote for each share of common stock owned on the books of the Company as of the Record Date and a majority of the votes cast shall decide the outcome of each such matter. Abstentions will be included in the vote totals and, as such, will have the same effect on proposals as a negative vote. Broker non-votes, if any, will not be included in vote totals and, as such, will have no effect on any proposal.
