Bank of Marin Q3 2026 Profit Rises as Margin Expands

Bank of Marin Bancorp reported higher third-quarter earnings as an expanding net interest margin, loan growth and increased fee income outweighed a modest rise in credit provisions. Classified loans increased during the quarter, largely because of a single commercial real estate relationship, though the company said it expects no loss from that exposure.

The Novato, California-based parent of Bank of Marin posted third-quarter 2026 net income of $9.9 million, or $0.62 per diluted share, compared with $9.2 million, or $0.58 per share, in the second quarter and $7.5 million, or $0.47 per share, a year earlier. Return on average assets rose to 1.05% from 0.96% sequentially, while return on average tangible common equity increased to 12.26% from 11.56%.

For the first nine months of 2026, comparable diluted earnings per share increased 62% to $1.73 from $1.07 a year earlier. The prior-year non-GAAP figure excludes an after-tax loss tied to investment securities portfolio repositioning.

Margin and revenue strengthen

Net interest income increased to $31.4 million from $30.8 million in the previous quarter and $27.2 million a year earlier. The net interest margin widened by 10 basis points sequentially to 3.48%, primarily reflecting an 11-basis-point increase in average loan yields, a four-basis-point decline in deposit costs and the use of one-way deposit sales to improve the balance-sheet mix.

The tax-equivalent yield on interest-earning assets rose six basis points from the second quarter. New loans carried a weighted-average rate of 6.65%, above the 5.93% weighted-average rate on loan payoffs, supporting further improvement in portfolio yields.

Non-interest income rose 15.8% from the prior quarter to $3.7 million, including a $251,000 increase in service charges on business deposit accounts. Non-interest expense declined by about $1 million to $20.6 million after seasonally higher second-quarter costs, mainly in salaries and employee benefits. The efficiency ratio improved to 58.65% from 63.62%.

Loan growth supported by mortgage-pool purchase

Gross loans increased $43.4 million, or 2.1%, during the quarter to $2.14 billion. The expansion included $63.6 million of new loan fundings and the purchase of a $31.1 million California residential mortgage pool using excess liquidity. New loan commitments totaled $102.4 million, while year-to-date commitments increased 21% to $281.3 million.

Non-owner-occupied commercial real estate remained the largest portfolio category, accounting for 65% of total loans, followed by owner-occupied commercial real estate at 13%. The company said the portfolio was diversified across property types and counties. Its $41.5 million of non-owner-occupied office exposure in the city of San Francisco represented 2% of total loans and had a weighted-average loan-to-value ratio of 60%.

Deposits increased by $25.3 million during the quarter, including a $45 million rise in noninterest-bearing balances. Noninterest-bearing deposits reached 37.8% of total deposits, up from 36.7%, helping reduce the quarterly cost of deposits to 1.24% from 1.28%. Business customers accounted for 63.2% of deposit balances.

The loan-to-deposit ratio was 63.16%, and the bank reported $2.16 billion of net available liquidity, equal to 1.8 times estimated uninsured and uncollateralized deposits. Available sources included cash, unencumbered securities and unused borrowing capacity.

Credit metrics show a limited deterioration

Classified loans rose to 1.63% of total loans from 0.95% in the second quarter. The increase was driven mainly by the downgrade of a $14.1 million owner-occupied commercial real estate relationship facing what the company described as a borrower-specific challenge. The relationship was paying as agreed, and management said it saw no expected loss potential.

Non-accrual loans increased by $1.2 million to 0.45% of total loans from 0.40%, while the allowance for credit losses remained stable at 1.07% of loans. Bank of Marin recorded a $500,000 provision for loan losses and a $325,000 provision for unfunded commitments, both associated with loan growth. There were no net charge-offs in the quarter.

Capital ratios remained above regulatory well-capitalized thresholds. Bancorp’s total risk-based capital ratio increased to 15.59%, and its Tier 1 leverage ratio rose to 9.04%. However, rising market interest rates reduced the tangible common equity-to-assets ratio to 8.05% and lowered tangible book value per share to $18.81. The available-for-sale securities portfolio carried $74 million of net pretax unrealized losses at quarter-end.

Management’s stated priorities remain high-quality loan growth, additional non-interest income, efficiency gains, selective acquisitions and investment in talent and technology. The company also said its capital stress testing indicates that regulatory ratios would remain above well-capitalized and internal minimum levels across its five-year forecast horizon under the scenarios tested.

Interest-rate movements remain a material uncertainty. The bank’s simulation estimated that an immediate 100-basis-point decline in rates would reduce net interest income by 2.6% in the first year and 5.4% in the second year. Other disclosed risks include economic uncertainty, deposit flows, commercial real estate values, inflation, tariffs and trade policy, regulation, cybersecurity threats, natural disasters and potential deterioration in loan credit quality.
