The complaint asserts that Coastal Financial failed to disclose the material deterioration of its CCBX partner loan portfolio, which accounted for approximately $500 million in assets. Despite repeated assurances regarding the strength of its credit protections, the company allegedly maintained inadequate risk management and monitoring practices. These oversights left Coastal exposed to significant credit losses that were hidden from the market.

The consequences of these omissions surfaced on July 30, 2026, when the firm reported a $42.1 million GAAP net loss. This shortfall was driven by a $68.8 million credit expense tied to a single CCBX partnership. Following the disclosure, Coastal stock plummeted $30.75 per share, representing a 43.5% decline in a single trading session. Investors seeking to participate in the class action must file as lead plaintiffs by December 1, 2026.
