Coastal Financial shares plunged 43.5% on July 30 after the Everett, Washington-based bank posted a $42.1 million quarterly net loss tied to its CCBX Banking-as-a-Service segment.
"We're focused on when Coastal first detected this single partner problem and whether it may have misled investors about the effectiveness of its initial underwriting and ongoing credit risk management," Reed Kathrein, the Hagens Berman partner leading the firm's investigation, said.
The Q2 2026 loss of $2.76 per diluted share reversed net income of $12 million, or $0.78 a share, a year earlier. The swing was driven by $68.8 million in pre-tax charges tied to one CCBX partner relationship, including a $46 million valuation adjustment to credit enhancement assets and a $22.8 million spike in credit loss provisions. The company also disclosed the impending departure of its chief financial officer ahead of the release.
CCB shares fell $30.75, or 43.5%, to close at $39.91 on heavy volume, down from a $70.66 close the prior session. Hagens Berman opened its investigation Aug. 26, and Bleichmar Fonti & Auld has launched a separate probe into whether Coastal misled investors about the credit quality of its BaaS partner relationships.
Coastal enables digital financial service providers, brands, and fintech partners to offer banking services through its CCBX platform, which has been the bank's primary growth engine. The company had repeatedly assured investors that internal safeguards protected its balance sheet, requiring partner institutions to submit all lending policies, scorecards, and models for approval before launching products, with independent firms conducting regular loan reviews.
The investigation centers on whether those public filings overstated the strength of that partner screening and third-party oversight, and whether executives issued materially false statements about the true credit quality and underwriting of loans originated through CCBX.
The collapse has drawn scrutiny to the BaaS model, where banks rely on fintech partners to originate consumer loans, and raises questions about risk controls across the sector. Coastal's next catalyst is any restatement, regulatory action, or further disclosure tied to the CCBX partner relationship, which the company has not yet named. Whistleblowers with non-public information about the bank's loan underwriting or partner oversight can qualify for SEC rewards of up to 30 percent of any successful recovery.
