Pomerantz LLP has opened an investigation into Coastal Financial Corp., adding to legal scrutiny already disclosed by Hagens Berman and Bleichmar Fonti & Auld after the bank's 43.5% one-day share-price drop on July 30, 2026. Coastal reported a GAAP net loss of $42.1 million, or $2.76 per diluted share, for the second quarter, which CEO Eric Sprink said was driven almost entirely by $68.8 million in pre-tax accounting adjustments associated with a defined CCBX portfolio company and its consumer loan portfolio. The stock fell $30.75 to close at $39.91 that day. Earlier law-firm announcements said they were examining whether Coastal and certain executives adequately disclosed the credit quality, risk profile and underwriting oversight of loans tied to its CCBX banking-as-a-service business, including charges they said consisted of a $46 million valuation adjustment to credit enhancement assets and a $22.8 million increase in credit loss provisions. Hagens Berman also cited Coastal's announcement of the impending departure of its Chief Financial Officer as an additional source of market concern. Pomerantz said it is investigating whether Coastal and certain officers or directors engaged in securities fraud or other unlawful business practices.
