Third Coast Bancshares, Inc. and Keystone Bancshares, Inc. are proposing a strategic bank merger in Texas. Arch Merger Sub, a Third Coast subsidiary, will merge into Keystone, which will then be combined into Third Coast, leaving Third Coast as the surviving company. Each Keystone common share will convert at closing into either 0.45925 shares of Third Coast common stock or a cash amount equal to 0.45925 multiplied by the volume‑weighted average price of Third Coast shares over a specified 20‑day trading period, at each holder’s election, subject to a total cash cap of $20,000,000. If cash elections exceed that cap, payments will be prorated.
The exchange ratio may be reduced if Keystone’s adjusted equity is below $94,576,000 at a defined calculation date. Based on recent examples in the document, the implied value of the per‑share merger consideration has generally been in the high‑$17 to low‑$18 range, assuming no downward adjustment. Using current share counts and the cash cap, former Third Coast shareholders are expected to own approximately 84% of the combined company and former Keystone shareholders approximately 16% after closing.
On a pro forma basis as of September 30, 2025, the combined company would have total assets of about $6.11 billion, loans of about $5.01 billion, deposits of about $5.27 billion and shareholders’ equity of about $606 million. Pro forma net income available to common shareholders is shown as $52.1 million for the nine months ended September 30, 2025 and $39.9 million for 2024, with basic pro forma earnings per share of $3.07 and $2.38, respectively.
