The litigation centers on claims that Coastal Financial failed to disclose significant deterioration within its CCBX partner loan portfolio. According to the filing, the company allegedly misrepresented the adequacy of risk management practices and the protection offered by partner indemnification agreements, despite the portfolio holding roughly $500 million in loans.

Market confidence fractured on July 30, 2026, when the company revealed a $42.1 million GAAP net loss. This shortfall was driven by a $68.8 million credit expense linked to a single partner relationship, including a $48 million valuation adjustment. Following the disclosure, Coastal shares plummeted by $30.75, effectively wiping out approximately $470 million in market capitalization in a single session. Shareholders interested in serving as lead plaintiff in the ongoing action have been advised to contact the law firm Robbins LLP, which is managing the case on a contingency fee basis.
