Bank of Marin Bancorp Executive Vice President Expands Stock Holdings Through ESOP Allocations and Options

Executive Vice President's Growing Equity Position in Bank of Marin

Brandi Campbell, serving as Executive Vice President at Bank of Marin Bancorp, has systematically increased her beneficial ownership stake in the company through multiple channels over an eighteen-month period. The disclosure, filed on July 28, 2026, details transactions beginning December 31, 2024, and continuing through May 14, 2026. Campbell's equity accumulation reflects participation in the company's ESOP program as well as the vesting and holding of stock options granted under the company's equity compensation structure. These transactions demonstrate Campbell's direct financial interest in the performance and long-term value of the bank.

The reporting person's address is listed as 504 Redwood Boulevard, Suite 100, in Novato, California, which aligns with Bank of Marin Bancorp's operational footprint in the North Bay region. Campbell filed the disclosure as a single reporting person with direct and indirect beneficial ownership across multiple security classifications. The transactions were reported by Krissy Meyer, Attorney-in-Fact, on behalf of Campbell, underscoring the routine nature of insider reporting compliance at the institution.

ESOP Allocations Drive Majority of Share Accumulation

The Employee Stock Ownership Plan represents the primary mechanism through which Campbell has accumulated additional shares during the reporting period. The first ESOP allocation of 770.54 shares was posted to Campbell's account on December 31, 2024, reflecting the 2024 annual allocation. This allocation carried a zero exercise price and was classified as an indirect beneficial ownership held through the ESOP vehicle. The cumulative beneficial ownership following this transaction reached 3,096.6039 shares held indirectly through the ESOP structure.

Additional ESOP activity occurred on December 31, 2025, when Campbell's account was credited with two separate allocations. The first represented the 2025 ESOP allocation of 838.32 shares, bringing total indirect holdings to 3,934.9239 shares. The second allocation, consisting of 123.7 shares, resulted from dividend reinvestment activity within the ESOP during 2025, further increasing Campbell's position to 4,058.6239 shares. A fourth allocation of 68.88 shares was posted on May 14, 2026, attributable to dividend reinvestment in the first portion of 2026. These ESOP transactions indicate that Campbell's compensation structure includes retirement and benefit accumulation through company stock ownership.

Stock Option Holdings Provide Additional Upside Exposure

Beyond ESOP participation, Campbell holds significant stock option positions that provide exposure to Bank of Marin Bancorp's future stock price appreciation. The disclosure reveals four distinct stock option grants held directly by Campbell. The options feature varying strike prices and vesting schedules, with exercise prices ranging from $34.03 to $40.10 per share. The earliest options, with an exercise price of $38.11 per share, are exercisable immediately with an expiration date of October 29, 2031, and represent 1,829 shares. These options appear to have vested over a period following their grant date of October 29, 2021.

Three additional option grants feature a vesting schedule of 33 percent per year beginning on the first anniversary of the grant date, as noted in the explanation of responses section. These grants include 300 shares at $40.10 per share (exercisable and expiring March 2, 2030); 926 shares at $38.25 per share (exercisable and expiring March 1, 2031); and 1,709 shares at $34.03 per share (exercisable and expiring March 1, 2032). The cumulative option holdings total 4,764 shares across these four grants, providing Campbell with substantial leverage to any appreciation in Bank of Marin Bancorp's stock price above the respective strike prices. The mix of older and newer grants suggests ongoing equity compensation as part of her executive compensation package.

Direct and Indirect Beneficial Ownership Structure

The disclosure distinguishes between Campbell's direct and indirect beneficial ownership across the various security classes. Direct ownership consists entirely of the stock options detailed in Table II, where Campbell holds individual option grants in her own name or under her direct control. These direct option holdings total 4,764 shares of common stock underlying the various option agreements. All ESOP-related share accumulations are classified as indirect beneficial ownership, meaning Campbell benefits from these shares through the ESOP trust structure rather than holding them in registered form.

The company also disclosed that Campbell holds 22,540 shares of common stock directly, as shown in the final line of Table I. This figure represents a substantial direct equity position independent of the ESOP and option holdings. The combination of direct common stock ownership, ESOP indirect holdings, and option positions demonstrates a multi-layered equity stake in Bank of Marin Bancorp. This diversified ownership structure is typical for senior executives at publicly traded financial institutions and aligns Campbell's personal financial interests with shareholder value creation.

Timing and Sequence of ESOP Allocations

The pattern of ESOP allocations disclosed in the filing follows a predictable annual cycle supplemented by ongoing dividend reinvestment. The year-end allocations on December 31 for both 2024 and 2025 represent standard employer contributions to the ESOP, a tax-advantaged retirement benefit vehicle commonly used by banks and other corporations. These allocations typically reflect a portion of the company's profits or a percentage of employee compensation, though the specific formula or contribution percentage is not disclosed in this filing. The zero-dollar transaction price associated with ESOP allocations is standard, as these shares are contributed by the employer rather than purchased by the employee.

Dividend reinvestment activity during 2025 and early 2026 indicates that Bank of Marin Bancorp pays regular dividends on its common stock, and that the ESOP automatically reinvests these distributions to purchase additional shares. The May 14, 2026, allocation of 68.88 shares from dividend reinvestment suggests that quarterly or semi-annual dividend payments during early 2026 were sufficient to accumulate this fractional share quantity within the ESOP account. This reinvestment mechanism compounds Campbell's equity stake over time without requiring any cash outlay on her part, demonstrating the benefit of the ESOP as an employee wealth-building tool.

Regulatory Compliance and Insider Reporting Obligations

The Form 4 filing represents Campbell's compliance with Section 16(a) of the Securities Exchange Act of 1934, which requires officers, directors, and significant shareholders of publicly traded companies to report changes in their beneficial ownership. Campbell's position as Executive Vice President triggers these reporting obligations, ensuring transparency regarding insider holdings and transactions. The filing was submitted on July 28, 2026, and covers transactions occurring over an extended period, with the earliest dated December 31, 2024. The inclusion of historical transactions from December 2024 and throughout 2025 and early 2026 in a single filing may represent an amended or consolidated disclosure.

The disclosure includes standard regulatory language warning that intentional misstatements or omissions of facts in insider reporting constitute federal criminal violations under 18 U.S.C. Section 1001 and 15 U.S.C. Section 78ff(a). The filing was executed by Krissy Meyer, Attorney-in-Fact, on Campbell's behalf, indicating that corporate counsel or a designated representative authenticated the disclosure. This procedural compliance underscores the seriousness with which Bank of Marin Bancorp and its executives treat securities law obligations, a factor that may be relevant to investor confidence in the institution's governance practices.

Implications for Shareholder Monitoring and Corporate Governance

Insider transactions reported through Form 4 filings provide investors with direct evidence of how company executives are allocating their personal wealth relative to their employer's stock. Campbell's substantial accumulation of shares through both ESOP participation and the exercise or retention of options signals confidence in Bank of Marin Bancorp's financial position and growth prospects. An executive's willingness to hold significant equity stakes suggests belief in the company's strategic direction and future profitability. Conversely, unusual patterns of option exercise or share sales can trigger investigation by analyst and investor communities seeking to understand management's confidence levels.

The disclosure of Campbell's holdings also enables institutional investors and shareholder advocacy groups to monitor whether executive compensation structures align management interests with long-term shareholder value. The combination of ESOP participation, which creates retirement security, and appreciating options, which reward stock price growth, represents a balanced approach to executive incentive design. Investors monitoring Bank of Marin Bancorp may review Form 4 filings periodically to assess whether senior management is expanding or contracting its holdings, as these patterns can reflect broader confidence or uncertainty about the company's prospects within the banking sector.

Bank of Marin Bancorp's Equity Compensation Framework

Bank of Marin Bancorp's use of ESOP, stock options, and potentially other equity vehicles as part of its executive compensation structure reflects contemporary best practices in financial services compensation design. ESOP programs serve both to align employee interests with shareholder returns and to provide tax-advantaged retirement savings. The vesting schedules noted in the option grants, with a 33 percent annual vesting formula, are standard in the banking industry and encourage retention of key personnel by spreading the value realization over multiple years. The range of strike prices from $34.03 to $40.10 per share may reflect different grant periods and market conditions at the time of grant.

The diversity of compensation elements disclosed in Campbell's holdings—ESOP allocations, dividend reinvestment, multiple option tranches at different strike prices, and direct common stock ownership—creates a comprehensive equity stake that would benefit from sustained stock price appreciation and consistent dividend payments. This structure is typical of regional and community banks seeking to attract and retain experienced executives capable of navigating competitive market dynamics and regulatory requirements. Investors evaluating Bank of Marin Bancorp's management quality and incentive alignment may reference these insider holdings as one factor among many in assessing governance quality and executive motivation.

No Dilution or Market Impact Disclosure

The filing does not disclose any immediate market impact or share price movement related to these transactions. The ESOP allocations and option vesting represent internal equity restructuring within Campbell's personal holdings rather than open-market transactions that would directly affect Bank of Marin Bancorp's outstanding share count or trading activity. The ESOP allocations are funded through employer contributions and dividend reinvestment, both of which are ordinary business activities. No cash exercise of options is reported in this filing; the disclosure simply tracks the options held and their current status relative to vesting and expiration schedules.

The immediate share price impact was not clear from available public information at the time of this filing's release. Bank of Marin Bancorp's stock trades on the NASDAQ exchange under the ticker BMRC, and investors interested in understanding the market's reaction to insider holdings and transactions should consult real-time trading data, analyst reports, and the company's ongoing disclosure documents. The Form 4 filing itself does not constitute an event expected to trigger automatic price movement, as such filings are routine regulatory disclosures rather than announcements of material corporate developments or earnings news.
