Business Context and Reporting Period
Company: Bank of Marin Bancorp (BMRC)
Filing Type: Form 8-K (Current Report)
Date of Report: February 23, 2026
Subject: Non-reliance on previously issued financial statements and announcement of a restatement for the years ended December 31, 2023 and 2024, and interim periods through September 30, 2025.
Key Financial Metrics and Adjustments
The filing details a material reclassification of reciprocal network deposits and related interest expense. While total deposits, net income, and earnings per share remain unchanged, the composition of deposits and expense categories requires adjustment.
| Metric | Impact Direction | Notes |
|---|---|---|
| Non-Interest Bearing Deposits | Decrease | Reclassified to interest-bearing; significant reduction in reported balances (e.g., FY 2025 end-of-period decreased by $237.8 million). |
| Interest-Bearing Deposits | Increase | Corresponding increase to offset non-interest bearing reduction. |
| Interest Expense | Increase | Previously recorded as non-interest expense (deposit network fees). |
| Non-Interest Expense | Decrease | Reduced by the amount reclassified to interest expense. |
| Net Interest Income | Decrease | Reduced due to higher interest expense; no impact on Net Income. |
| Net Interest Margin (NIM) | Decrease | Reported NIM reduced (e.g., FY 2025 adjusted from 3.04% to 2.92%). |
| Cost of Deposits | Increase | Reflects higher interest expense relative to total deposits. |
| Efficiency Ratio (GAAP) | Variable | Impacted by changes in both non-interest expense and net interest income. |
Material Changes Versus Prior Periods
The filing does not report operational changes in business performance but rather corrects historical accounting errors. The material changes are strictly reclassifications:
- Deposit Mix: The percentage of non-interest bearing deposits to total deposits is significantly lower in the adjusted figures (e.g., FY 2025 adjusted to 36.7% from 43.7% as reported).
- Expense Classification: Interest expense is higher, and non-interest expense is lower in all affected periods compared to previously reported figures.
- Profitability Metrics: Net Interest Margin and Cost of Deposits metrics are adjusted downward and upward respectively, though Net Income remains constant.
Guidance, Outlook, Risks, and Contingencies
Management Commentary: The Board concluded that previously issued financial statements should no longer be relied upon. The errors were identified during the annual review for the year ended December 31, 2025.
Next Steps: The Company plans to restate consolidated financial statements for all affected periods and file them with the SEC as soon as practicable.
Risks and Controls:
- Internal Controls: Management is evaluating Internal Control over Financial Reporting (ICFR) as of December 31, 2025. A material weakness may be identified and disclosed in the upcoming 10-K.
- Forward-Looking Statements: The summary of adjustments is preliminary; final restatement figures may differ materially.
Investor Verification Checklist
- Verify the final restated financial statements once filed to confirm the exact impact on Net Interest Margin and Cost of Deposits.
- Monitor the upcoming Form 10-K for the year ended December 31, 2025, for disclosure of any material weakness in Internal Controls over Financial Reporting (ICFR).
- Review the reclassified deposit mix to assess the true cost of funds and liquidity profile.
- Confirm that the reclassification of expenses does not alter the Company's regulatory capital ratios or compliance status.
