Further Improvements in Net Interest Margin and Asset Quality

Bank of Marin Bancorp, "Bancorp" (NASDAQ:BMRC), parent company of Bank of Marin, "Bank," announced net income of $8.5 million for the first quarter of 2026, compared to a net loss of $39.5 million due to the impact of its balance sheet restructuring (net income of $9.4 million, non-GAAP) for the fourth quarter of 2025. Largely as a result of continued net interest margin expansion, net income increased 75% year over year from $4.9 million for the same period in the prior year. Notably, the Bank showed continued seasonal improvement in loan originations and demonstrated significant improvement in credit quality as evidenced by a substantial decline in its non-accrual and classified loans, while deposit balances increased with flat cost of deposits. Diluted income per share was $0.53 for the first quarter, compared to diluted loss per share of $2.49 (diluted earnings per share of $0.59, non-GAAP) for the prior quarter. Results for the prior quarter include pre-tax losses on the sale of securities of $69.5 million, incurred as part of the repositioning to improve the bank's future earnings.

Concurrent with this release, Bancorp issued presentation slides providing supplemental information, some of which will be discussed during the first quarter 2026 earnings call. The earnings release and presentation slides are intended to be reviewed together and can be found online on Bank of Marin's website at www.bankofmarin.com. under "Investor Relations."

"During the first quarter, we remained focused on continued improvement in core banking fundamentals. We followed a strong fourth quarter with a seasonally high level of new loan originations and grew our deposits without increasing their total cost," said President and CEO Tim Myers. "At the same time, we sold our largest non-performing assets with no further impact to net income and showed notable improvement across key credit risk metrics."

Bancorp also provided the following highlights for the first quarter of 2026:

The first quarter tax-equivalent net interest margin improved 6 basis points over the preceding quarter to 3.24% from 3.18%, largely due to the effects of the securities repositioning in the fourth quarter of 2025, which provided a 21 basis point increase in annualized net interest margin for the first quarter over the prior quarter. The tax-equivalent net interest margin for the three months ended March 31, 2026 improved 47 basis points over the same period of the prior year due to the increase in deposits at a decreased average cost, higher average loan balances and rates, and the favorable impact of the securities repositioned in the second and fourth quarters of 2025, which resulted in higher yielding assets during the three months ended March 31, 2026.
During the quarter, we worked diligently to improve our credit quality. We sold our longest tenured classified and non-accrual loans totaling $16.3 million, which were downgraded to substandard in 2021, and moved to non-accrual in 2024. At that time, we recorded specific reserves of $7.3 million based on property valuations. The note sales proceeds validated our reserve assumptions, with the charge-offs equaling the specific amounts reserved in our allowance for credit losses. While other workouts were offset by new downgrades, the impact of the note sales on credit metrics was substantial: Non-accrual loans declined from 1.27% of assets to 0.41%, and the ratio of classified to total loans decreased from 1.51% to 0.85%. Notably, following the note sales virtually all remaining non-accrual balances are comprised of one non-owner occupied commercial real estate loan that has no loss expectations based on underlying valuation and cash flow.
There was no provision for credit losses on loans in the first quarter of 2026 compared to a provision of $300 thousand in the prior quarter. The allowance for credit losses was 1.08% and 1.42% of total loans at March 31, 2026 and December 31, 2025, respectively due to the $7.2 million of charge-offs taken against the specific reserves on the two loans sold, noted above. The charge-offs were fully offset by specific reserves already in place.
Return on average assets ("ROA") and return on average equity ("ROE") increased on a GAAP basis from the prior quarter, as shown below, primarily due to the increased net income compared to the prior quarter which included losses from the sale of securities from the balance sheet repositioning. ROA and ROE on a non-GAAP basis both decreased from the prior quarter mainly due to decreased non-GAAP income quarter over quarter. Income was impacted by a lower day count, quarter over quarter, as well as an interest recovery on a loan in the fourth quarter of $667 thousand that was not repeated in the first quarter. The efficiency ratio on a non-GAAP basis also worsened from last quarter. Both the efficiency ratio and the returns on average assets and equity were affected by increased non-interest expense in the first quarter, mainly within salaries and related benefits and due to the annual charitable contributions made in the first quarter of 2026. Non-GAAP ratios for the prior quarter exclude the loss on security sales in the prior quarter, all other factors unchanged, and with adjustments made based on our blended statutory tax rate of 29.56%.

Despite a reduction in the average cost of interest bearing deposits from 2.16% to 2.10% in the first quarter of 2026 compared to the prior quarter, the average cost of total deposits remained flat at 1.35% due to a reduction in non-interest bearing deposits. Non-interest bearing deposits continued to make up a strong portion of total deposits at 35.9% as of March 31, 2026, compared to 36.7% last quarter.
Total deposits increased 0.37% to $3.428 billion as of March 31, 2026 compared to $3.416 billion as of December 31, 2025 due largely to inflows from existing customers as well as new relationships to the Bank in the quarter.
Capital was above well-capitalized regulatory thresholds. Total risk-based capital was 15.26% as of March 31, 2026 for Bancorp compared to 15.25% as of December 31, 2025. Bancorp's tangible common equity to tangible assets ("TCE ratio") was 8.33% as of March 31, 2026.
The Board of Directors declared a cash dividend of $0.25 per share on April 23, 2026, which was the 84th consecutive quarterly dividend paid by Bancorp. The dividend is payable on May 14, 2026 to shareholders of record at the close of business on May 7, 2026.

"Our fourth quarter balance sheet repositioning drove a reported 6 basis point expansion of net income during the quarter, or 14 basis points when adjusting for the fourth quarter recovery of non-accrual loan interest and fees," said Chief Financial Officer Dave Bonaccorso. "While our cost of deposits was unchanged this quarter at 1.35% due to some changes in mix, our spot cost of deposits improved to 1.31% as of March 31st and we continue to believe that deposit and loan repricing benefits will allow us to further expand net interest margin during the remainder of 2026."

Loans and Credit Quality

Loans decreased by $5.1 million for the first quarter and totaled $2.116 billion as of March 31, 2026 compared to $2.121 billion as of December 31, 2025. First quarter 2026 new fundings were $60.8 million compared to $47.4 million in the first quarter of 2025.

As discussed above, our continued discipline in credit management led to significant improvements in our credit quality this quarter including non-accrual balances, classified loan balances and past due loan balances. Non-accrual loans declined by $18.3 million during the quarter to $8.6 million, or 0.41% of total loans, compared to $26.9 million, or 1.27%, at December 31, 2025. The reduction was driven primarily by the sale of the two non-owner occupied commercial real estate loans totaling $16.3 million discussed above. The remaining $8.6 million of non-accrual loans consists primarily of one $8.2 million non-owner occupied commercial real estate relationship which continues to exhibit conforming loan-to-value and debt service coverage metrics but remains on non-accrual due to an ongoing dispute related to extension terms following its late 2023 maturity.

Classified loans declined by $14.2 million during the first quarter to $17.9 million, down from $32.1 million at December 31, 2025. The improvement was driven primarily by the sale of the two non-owner occupied commercial real estate loans previously discussed, along with payoffs totaling $2.4 million on two additional loans. These positive trends were partially offset by the downgrade of two non-owner occupied commercial real estate loans totaling $5.7 million into the classified category. Overall, asset quality metrics improved during the quarter, and we remain disciplined and proactive in our credit management approach with close monitoring and active resolution efforts across the portfolio.

Accruing loans past due 30 to 89 days totaled $683 thousand at March 31, 2026, down from $2.8 million at December 31, 2025.

Loans designated as special mention, which are not considered adversely classified, remained relatively stable at $119.4 million at March 31, 2026 compared to $118.0 million at December 31, 2025.

Net charge-offs totaled $7.3 million in the first quarter of 2026 compared to $64 thousand in the prior quarter. Approximately $7.2 million of the charge-offs were related to the two non-accrual loans that were sold, as previously discussed. These charge-offs were fully offset by specific reserves that were already in place for the two loans.

There was no provision for credit losses on loans recorded in the first quarter of 2026 compared to a provision of $300 thousand in the prior quarter. The ratio of allowance for credit losses to total loans declined to 1.08% at March 31, 2026 from 1.42% at December 31, 2025 due to the charge-offs taken and the related decrease in specific reserves required.

There was no provision for credit losses on unfunded loan commitments in the first quarter of 2026 compared to a provision of $185 thousand in the prior quarter.

Cash, Cash Equivalents and Restricted Cash

Total cash, cash equivalents and restricted cash were $236.6 million at March 31, 2026, an increase of $11.3 million compared to $225.3 million at December 31, 2025 largely due to a $12.6 million increase in deposits.

Investments

The investment securities portfolio totaled $1.326 billion at March 31, 2026, a decrease of $1.6 million from December 31, 2025. The decrease in the portfolio was primarily due to principal repayments and calls/maturities totaling $54.5 million and $4.7 million, respectively, and an increase of $7.6 million in unrealized losses on available-for-sale ("AFS") securities, partially offset by purchases of AFS securities of $65.2 million. The portfolio is eligible for pledging to FHLB or the Federal Reserve as collateral for borrowing, and is comprised of high credit quality investments with an average effective duration of 2.90. The portfolio generates cash flows monthly from interest, principal amortization and payoffs, which supports the Bank's liquidity. Those cash flows totaled $73.4 million and $84.2 million in the first quarter of 2026 and the fourth quarter of 2025, respectively.

Deposits

Deposits increased $12.6 million, or 0.4%, to $3.428 billion at March 31, 2026, compared to $3.416 billion at December 31, 2025 primarily due to inflows from existing relationships as well as new relationships. The majority of this increase was due to an increase of $58.3 million in interest bearing transaction accounts, partially offset by a decrease of $22.2 million in non-interest bearing deposits and a decrease of $25.6 million in time accounts. This growth excludes the additional $27.3 million in deposits the Bank maintains off balance sheet as one-way sales. As of March 31, 2026, total one-way sales increased from $51.2 million to $78.5 million. The majority of the decrease in non-interest bearing deposits aligns with one anticipated client event while the decrease in time accounts reflects prudent management of the Bank's cost of deposits. Non-interest bearing deposits continued to make up a strong 35.9% of total deposits at March 31, 2026, compared to 36.7% at December 31, 2025. The Bank's competitive and balanced approach to relationship management and focused outreach to customers seeking alternative options for banking solutions generated nearly 1,000 new accounts during the first quarter, 42% of which were new relationships.

Borrowings and Liquidity

At March 31, 2026, the Bank had no outstanding short-term borrowings, consistent with December 31, 2025. Net available funding sources, including unrestricted cash, unencumbered available-for-sale securities and total available borrowing capacity totaled $2.185 billion, or 64% of total deposits and 221% of estimated uninsured and/or uncollateralized deposits as of March 31, 2026. Additionally, as part of our active balance sheet management, the Bank maintained $78.5 million in deposits off-balance sheet with deposit networks at March 31, 2026, compared to $51.2 million at December 31, 2025.

The following table details the components of our contingent liquidity sources as of March 31, 2026.

Subordinated Notes

During the fourth quarter of 2025, Bancorp issued Fixed-to-Floating Subordinated Notes of $45.0 million with a final maturity date of December 1, 2035, to certain investors in a private placement to strengthen capital ratios as part of the balance sheet repositioning. The interest rate of the Bank's subordinated notes is 6.75%, payable semi-annually in arrears on June 1 and December 1 of each year, commencing on June 1, 2026. After December 1, 2030, the interest rate will be variable and equal Three-Month Term SOFR plus 335 basis points, resetting quarterly. Subordinated notes outstanding were $43.9 million, net of issuance costs, at March 31, 2026.

Capital Resources

Our capital ratios are summarized in the table below.

Capital Ratios	March 31, 2026				December 31, 2025				March 31, 2025
(dollars in thousands)	Bancorp		Bank		Bancorp		Bank		Bancorp		Bank
Common Equity Tier 1 to RWA	12.61	%	13.17	%	12.34	%	12.69	%	16.69	%	16.54	%
Total Tier I to RWA	12.61	%	13.17	%	12.34	%	12.69	%	15.49	%	15.32	%
Total Capital to RWA	15.26	%	14.09	%	15.25	%	13.90	%	10.62	%	10.46	%
Tier I Leverage Ratio to Avg Assets	8.23	%	8.59	%	8.26	%	8.49	%	15.49	%	15.32	%
Tangible Common Equity to TA	8.33	%	8.70	%	8.35	%	8.59	%	8.35	%	8.59	%

Bancorp's tangible common equity to tangible assets ("TCE ratio") was 8.33% at March 31, 2026, compared to 8.35% at December 31, 2025. The Bank's capital plan and point-in-time capital stress tests indicate that 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 $30.3 million for the first quarter of 2026, a $521 thousand increase from the prior quarter. This was driven by an increase of $63.4 million in average earning assets including a $42.5 million increase in average investment securities, combined with a 45 basis point increase in average yield on investment securities, resulting in a $1.9 million increase in investment securities interest income.

The tax-equivalent net interest margin increased 6 basis points to 3.24% for the first quarter of 2026, compared to 3.18% for the prior quarter. The repositioning of securities added 21 basis points to the margin during the first quarter. This was partially offset by lower average interest-earning deposit balances at the Federal Reserve Bank and lower rates due to Federal Reserve rate cuts of 25 basis points in both October and December of 2025, that decreased the margin by 4 basis points, lower average loan yields during the quarter impacted by an interest recovery in the fourth quarter of $667 thousand and by approximately $195 million in loans tied to prime or SOFR whose rates declined quarter over quarter that decreased the margin by 5 basis points, and average subordinated note costs for the full quarter that decreased the margin by 5 basis points.

Non-Interest Income (Loss)

Non-interest income was $3.8 million for the first quarter of 2026, compared to a net non-interest loss of $66.6 million for the prior quarter. The increase of $70.5 million from the prior quarter was primarily attributable to a loss of $69.5 million on the sale of available-for-sale investment securities during the prior quarter. Excluding the loss on sale, prior quarter non-interest income was $2.8 million. The $1.0 million increase in the first quarter of 2026 on a non-GAAP basis was primarily attributed to an increase of $484 thousand in dividend income on FHLB stock which included a $479 thousand special dividend and a $479 thousand death benefit on bank owned life insurance.

Non-Interest Expense

Non-interest expense totaled $22.5 million for the first quarter of 2026, compared to $20.0 million for the prior quarter, an increase of $2.5 million, primarily driven by an increase of $2.0 million in salaries and related benefits expense in the first quarter of 2026. Consistent with annual adjustments and our compensation cycle, expense increases included updated incentive bonus accruals, 401(k) contribution matching, profit sharing accruals, payroll taxes, and stock-based compensation grants, in addition to lower deferred loan origination costs in the quarter. Additionally, the bank completed the bulk of its anticipated 2026 charitable giving during the first quarter resulting in $437 thousand in expense.

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 providing selected financial measures that exclude the loss on sale of securities 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.

Forward-Looking Statements

This release may contain certain forward-looking statements that are based on management's current expectations regarding economic, legislative, and regulatory issues that may impact Bancorp's earnings in future periods. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts. They often include the words "believe," "expect," "intend," "estimate" or words of similar meaning, or future or conditional verbs such as "will," "would," "should," "could" or "may." Factors that could cause future results to vary materially from current management expectations include, but are not limited to, general economic conditions and the economic uncertainty in the United States and abroad, including economic or other disruptions to financial markets caused by the Trump administration's approach to tariffs and trade and the military action in Iran, acts of terrorism, war or other conflicts, impacts from inflation, supply chain disruptions, changes in interest rates (including the actions taken by the Federal Reserve to control inflation), California's unemployment rate, deposit flows, real estate values, and expected future cash flows on loans and securities; the impact of adverse developments at other banks, including bank failures, that impact general sentiment regarding the stability and liquidity of banks; costs or effects of acquisitions; competition; changes in accounting principles, policies or guidelines; changes in legislation or regulation; natural disasters (such as wildfires and earthquakes in our area); adverse weather conditions; interruptions of utility service in our markets for sustained periods; and other economic, competitive, governmental, regulatory and technological factors (including external fraud and cybersecurity threats) affecting our operations, pricing, products and services; and successful integration of acquisitions. These and other important factors are detailed in various securities law filings made periodically by Bancorp, copies of which are available from Bancorp without charge. Bancorp undertakes no obligation to release publicly the result of any revisions to these forward-looking statements that may be made to reflect events or circumstances after the date of this press release or to reflect the occurrence of unanticipated events.

¹Interest income/expense is divided by actual number of days in the period times 360 days to correspond to stated interest rate terms, where applicable.
²Yields on available-for-sale securities are calculated based on amortized cost balances rather than fair value, as changes in fair value are reflected as a component of stockholders' equity. Investment security interest is earned on 30/360 day basis monthly.
³Yields and interest income on tax-exempt securities and loans are presented on a taxable-equivalent basis using the Federal statutory rate of 21 percent.
⁴Average balances on loans outstanding include non-performing loans. The amortized portion of net loan origination fees is included in interest income on loans, representing an adjustment to the yield.
⁵Net loan origination costs in interest income totaled $398 thousand, $452 thousand, and $364 thousand for the three months ended March 31, 2026, December 31, 2025, and March 31, 2025, respectively.
