Third Coast Bancshares, Inc. filed an update providing supplemental disclosures about its planned merger with Keystone Bancshares, Inc. after receiving four demand letters claiming the original joint proxy statement/prospectus omitted material information. The company and Keystone deny these allegations but are adding details without changing the merger consideration or the timing of their shareholder meetings.
The new disclosures expand on Raymond James’ valuation work, including discounted cash flow assumptions, updated peer and transaction comparison tables, and additional fee information. Third Coast now shares unaudited financial projections for both banks through 2030, which Raymond James used in its fairness opinion. A pro forma analysis indicates the merger could be 1.9% dilutive to Third Coast’s estimated tangible book value per share and 0.4% dilutive on a fully diluted basis at March 31, 2026, but 5.2% and 5.3% accretive to estimated EPS in 2027 and 2028.

Pro forma analysis shows the merger is estimated to be 1.9% dilutive to tangible book value per share at March 31, 2026, but 5.2% and 5.3% accretive to Third Coast’s projected 2027 and 2028 EPS.
