Coastal Financial Investigated After 43% Stock Plunge

The scrutiny centers on Coastal Financial’s transparency following a disastrous second-quarter financial report released on July 30, 2026. The company posted a net loss of $42.1 million, a figure that fell significantly short of profit estimates. These losses were primarily tied to a single partnership within the CCBX segment, resulting in $68.8 million in pre-tax charges, including a $46 million valuation adjustment and a $22.8 million spike in credit loss provisions.

Hagens Berman partner Reed Kathrein is questioning when the company first identified issues with the partner relationship and whether executives accurately described their underwriting standards to shareholders. Before the market crash, Coastal Financial had maintained that its internal safeguards and third-party reviews were sufficient to protect its balance sheet. The instability was further exacerbated by the sudden departure of the company's Chief Financial Officer just before the earnings disclosure. Investors who suffered losses are now being urged to provide trading information, while the firm seeks potential whistleblowers with non-public knowledge of the company's internal controls.
