Bank of Marin Bancorp

2 serious warning signs in Bank of Marin Bancorp’s filings.

We look for five warning signs: doubt it can keep going, weak checks on its own accounts, a notice that its past accounts can't be relied on, a change of auditor, and one customer bringing in a big share of sales. We don't check lawsuits, investigations or debt yet.

We checked the auditor's report, internal controls, restatement notices, auditor changes and big customers in the 10-K filed 13 Mar 2026, plus the 10-Q filed 6 Aug 2026 and 7 later 8-Ks.
