• There was a $75 thousand provision for credit losses on loans in the first quarter of 2025 and no provision in the previous quarter. The allowance for credit losses was 1.44% of total loans at March 31, 2025 compared to 1.47% at December 31, 2024.

• Classified loans were 2.77% of total loans compared to 2.17% last quarter largely due to downgrades in one commercial relationship and one commercial real estate relationship during the quarter totaling $13.5 million.

• Non-accrual loans were 1.59% of total loans at quarter-end, down from 1.63% at December 31, 2024. The reduction in non-accrual balances included a $2.1 million non-owner occupied real estate loan sale that included a charge-off of $809 thousand.

• Total deposits of $3.302 billion as of March 31, 2025 were up $82.0 million compared to $3.220 billion as of December 31, 2024, mostly due to seasonal inflows and new deposit accounts added in the quarter.

• Capital was above well-capitalized regulatory thresholds with total risk-based capital ratios of 16.69% and 16.45% as of March 31, 2025 for Bancorp and the Bank, respectively, compared to 16.54% and 16.13% as of December 31, 2024. Bancorp's tangible common equity to tangible assets ("TCE ratio") was 9.82% as of March 31, 2025, and the Bank's TCE ratio was 9.66%. The Bancorp's TCE ratio net of after-tax unrealized losses on held-to-maturity securities as if the losses were realized¹ was 8.08% as of March 31, 2025.

• The Board of Directors declared a cash dividend of $0.25 per share on April 24, 2025, which represents the 80^th consecutive quarterly dividend paid by Bancorp. The dividend is payable on May 15, 2025, to shareholders of record at the close of business on May 8, 2025.

"The first quarter performance was negatively impacted by the proactive non-accrual note sale of a rapidly deteriorating acquired loan as well an increase in contributions expense from our annual grant program, the bulk of which has shifted from the second quarter into the first quarter," said Dave Bonaccorso, Executive Vice President and Chief Financial Officer. "Salaries and related benefits expense increased from the prior quarter due to fourth quarter incentive compensation accrual adjustments and reductions and customary first quarter increases for items including payroll taxes and 401k matching. Excluding charitable contributions and salaries and related benefits, our first quarter non-interest expense declined almost 1% compared to the fourth quarter of 2024 and almost 3% compared to the first quarter of 2024. We expect that 2025 will be a year of prudent expense management with targeted investments in people and technology made to scale our growth."

Loans and Credit Quality

Despite improved originations, loans decreased by $9.7 million for the first quarter of 2025 and totaled $2.074 billion as of March 31, 2025, compared to $2.083 billion as of December 31, 2024. Loan originations for the first quarter were $63.6 million ($47.4 million funded) including $50.2 million ($43.2 million funded) in commercial loans, which includes commercial and industrial, commercial real estate and construction. Funded commercial loans were more than five times those funded in the first quarter of prior year. The fourth quarter of 2024 included originations of $69.4 million ($47.1 million funded) and the first quarter of the prior year included total originations of $25.3 million ($12.4 million funded).

Loan payoffs were $25.5 million for the first quarter of 2025, compared to $36.7 million for the fourth quarter of 2024 and $21.8 million in the first quarter of the prior year. The decrease quarter over quarter was mostly within the commercial sector. Payoffs included $7.6 million in residential real estate loans. In addition, $31.8 million of loan amortization from scheduled repayments, including a net decrease of $9.5 million in credit line utilization, predominantly construction, contributed to the decline in loan balances for the quarter ended March 31, 2025.

Accruing loans past due 30 to 89 days totaled $6.0 million as of March 31, 2025, compared to $2.2 million as of December 31, 2024. Within the additions were two commercial loan maturities totaling $4.4 million that have since been approved to extend.

Non-accrual loans totaled $32.9 million, or 1.59% of the loan portfolio, at March 31, 2025, compared to $33.9 million, or 1.63% at December 31, 2024. The $1.0 million decrease resulted from the sale of one $2.1 million commercial real estate loan related to the $809 thousand charge-off discussed below, net paydowns of $370 thousand, one payoff of $100 thousand and two charged off loans totaling $16 thousand, partially offset by the addition of four loans totaling $1.7 million. Of the total non-accrual loans as of March 31, 2025, approximately 57% were paying as agreed, 90% were real estate secured, and all are being closely managed and monitored.

The Bank continues to uphold its conservative underwriting standards. In response to current market conditions, we continue to closely monitor our portfolio for signs of potential weakness to ensure proactive risk management and actively work towards a resolution on our classified loans. Classified loans increased by $12.3 million to $57.4 million as of March 31, 2025, from $45.1 million as of December 31, 2024. The increase was largely due to downgrades of one $7.1 million commercial relationship and two non-owner occupied real estate relationships totaling $7.2 million, partially offset by the sale of a $2.1 million non-owner occupied real estate loan.

Loans designated special mention, which are not considered adversely classified, decreased by $20.0 million to $88.9 million as of March 31, 2025, from $108.9 million as of December 31, 2024. The decrease was largely due to $14.2 million in downgrades to substandard risk rating and contractual paydowns and payoffs totaling $6.0 million.

There were $825 thousand in net charge-offs for the first quarter of 2025, including the $809 thousand charge-off of an acquired commercial non-owner occupied real estate loan the Bank had previously reserved $449 thousand for as of December 31, 2024. There was an additional decline in the financial condition of the borrower and guarantor and the value of the collateral during the first quarter that led to the Bank proactively selling the note in March rather than pursuing the additional costly steps of liquidating after foreclosure. It had been on non-accrual since late 2023. This compared to net charge-offs of $19 thousand for the fourth quarter of 2024.

There was a $75 thousand provision for credit losses on loans in the first quarter of 2025 and no provision in the fourth quarter of 2024. Modest deterioration in economic forecast, effects from the noted charge-offs, and the pooled and individual total loan balance declines this quarter contributed to the provision. The ratio of allowance for credit losses to total loans was 1.44% at March 31, 2025, compared to 1.47% at December 31, 2024. There was no provision for credit losses on unfunded loan commitments in the first quarter of 2025 or in the fourth quarter of 2024.

Cash, Cash Equivalents and Restricted Cash

Total cash, cash equivalents and restricted cash were $259.9 million at March 31, 2025, an increase of $122.6 million compared to $137.3 million at December 31, 2024 largely due to the $82.0 million growth in deposits and the paydowns of investment securities and loans.

Investments

The investment securities portfolio totaled $1.241 billion at March 31, 2025, a decrease of $26.1 million from December 31, 2024. The decrease was primarily the result of principal repayments and maturities totaling $63.0 million, offset by $33.6 million available-for-sale securities purchases and a $3.3 million improvement in unrealized losses on available for sale securities. Both the available-for-sale and held-to-maturity portfolios are eligible for pledging to FHLB or the Federal Reserve as collateral for borrowing. The portfolios are comprised of high credit quality investments with average effective durations of 3.27 on available-for-sale securities and 5.61 on held-to-maturity securities. Both portfolios generate cash flows monthly from interest, principal amortization and payoffs, which supports the Bank's liquidity. Those cash flows totaled $72.8 million and $22.2 million in the first and fourth quarters of 2025 and 2024, respectively.

Deposits

Deposits increased $82.0 million to $3.302 billion at March 31, 2025, compared to $3.220 billion at December 31, 2024. Non-interest bearing deposits made up 43.2% of total deposits at March 31, 2025, compared to 43.5% at December 31, 2024. The Bank's competitive and balanced approach to relationship management and focused outreach to customers seeking alternative options for banking solutions generated over 1,000 new accounts during the first quarter, 44% of which were new relationships (excluding new reciprocal accounts).

Borrowings and Liquidity

At March 31, 2025, the Bank had no outstanding borrowings, consistent with December 31, 2024. While available as a liquidity source, we have not utilized brokered deposits. Net available funding sources, including unrestricted cash, unencumbered available-for-sale securities and total available borrowing capacity totaled $1.917 billion, or 58% of total deposits and 203% of estimated uninsured and/or uncollateralized deposits as of March 31, 2025.

The following table details the components of our contingent liquidity sources as of March 31, 2025.

Capital Resources

The total risk-based capital ratio for Bancorp was 16.69% at March 31, 2025, compared to 16.54% at December 31, 2024. The increase was largely due to a $3.3 million improvement in unrealized losses on available for sale securities. The total risk-based capital ratio for the Bank was 16.45% at March 31, 2025, compared to 16.13% at December 31, 2024.

Bancorp's tangible common equity to tangible assets ("TCE ratio") was 9.82% at March 31, 2025, compared to 9.93% at December 31, 2024. The TCE ratio decreased slightly quarter over quarter due mainly to the increase in tangible total assets. The capital plan and point-in-time capital stress tests indicate that Bank of Marin and Bancorp capital ratios will remain above regulatory well-capitalized and internal policy minimums throughout a five-year forecast horizon and across stress scenarios such as additional unrealized losses on the investment portfolio, additional deposit growth or decline, loan credit quality deterioration, and potential share repurchases.

Earnings

Net Interest Income

Net interest income totaled $24.9 million for the first quarter of 2025, a $284 thousand decrease from the prior quarter related to the decrease of $36.3 million in average earning assets including a $8.0 million decrease in average loan balances over the quarter, reducing interest income by $1.2 million. This was significantly offset by the reduction of interest expense of $1.0 million despite average interest-bearing deposit growth of $7.2 million over the quarter. Average money market balances increased by 2.20% and average time deposits decreased by 11.31% while the average cost of those deposits decreased by 17 and 31 basis points, respectively, due to relationship-focused rate management, contributing to the reduced costs.

The tax-equivalent net interest margin was 2.86% for the first quarter of 2025, compared to 2.80% for the prior quarter. Lower cost of funds, as referenced above, contributed 7 basis points, while lower average interest-earning deposit balances with banks and the December fed funds rate cut of 25 basis points, reducing the earning power on those deposits, reduced the margin by 5 basis points. Minor changes in the loan and investment mix contributed to the margin by 2 basis points each, resulting in the 6 basis point margin expansion.

Non-Interest Income

Non-interest income was $2.9 million for the first quarter of 2025, compared to $2.8 million for the prior quarter. The increase from the prior quarter was primarily attributed to a $71 thousand death benefit received on bank owned life insurance.

Non-Interest Expense

Non-interest expense totaled $21.3 million for the first quarter of 2025, compared to $18.3 million for the prior quarter, an increase of $2.9 million. Salaries and related benefits increased $2.6 million, due to various factors, both in prior and current quarter. Last quarter, incentive, stock-based compensation and profit sharing accrual adjustments reduced expenses. In the first quarter of 2025, there was an increase to the 401(k) contribution matching associated with the usual reset, lower deferred loan origination costs, bonus accruals based on budget, stock-based compensation grants and increased salary costs due to new talent acquisition. In order to better serve the timing needs of our non-profit communities, the bulk of our charitable contributions were pulled forward into the first quarter from the second quarter. In the first quarter, we incurred $403 thousand of contributions expense which compares to $30 thousand in the fourth quarter of 2024 and $12 thousand in the first quarter of 2024.

Statement Regarding use of Non-GAAP Financial Measures

Financial results are presented in accordance with GAAP and with reference to certain non-GAAP financial measures. Management believes that, given industry turmoil that largely began in the first quarter of 2023, the presentation of Bancorp's non-GAAP TCE ratio reflecting the after tax impact of unrealized losses on held-to-maturity securities provides useful supplemental information to investors because it reflects the level of capital remaining after a hypothetical liquidation of the entire securities portfolio. In addition, management believes that providing selected financial measures excluding the loss on sale of securities discussed above is useful to investors as the strategic short-term loss taken for long-term profitability makes the operational performance difficult to compare to other periods. Because there are limits to the usefulness of this or any other non-GAAP measure to investors, Bancorp encourages readers to consider its annual and quarterly consolidated financial statements and notes related thereto for their entirety, as filed with the Securities and Exchange Commission, and not to rely on any single financial measure. A reconciliation of the GAAP financial measures to comparable non-GAAP financial measures is presented below.

Reconciliation of GAAP and Non-GAAP Financial Measures

Share Repurchase Program

On July 21, 2023, the Board of Directors approved the adoption of Bancorp's share repurchase program for up to $25.0 million and expiring on July 31, 2025. There were no repurchases in the first quarter of 2025 or in the fourth quarter of 2024.
