The document, submitted as Exhibit 99.2 to a Form 8-K, outlines the proposed acquisition of Great Plains by Third Coast and includes forward-looking statements regarding the expected completion date and financial benefits of the transaction.

The presentation identifies the deal as a move to create a premier Southwestern franchise. It provides combined financial highlights for the two institutions, listing Third Coast with 20 assets and 44 gross loans, while Great Plains is noted with 23 assets and 40 gross loans. The combined entity is projected to have approximately $9.0 billion in assets, $7.3 billion in gross loans, and $7.8 billion in held-for-investment deposits.

Key financial ratios cited in the presentation include a 9.0% CET1 ratio, a 9.8% TRBC ratio, and an 11.5% TCE/TA ratio for the combined entity. Third Coast projects a 2027 return on average assets of approximately 1.3%, a return on average tangible common equity of approximately 15%, and an efficiency ratio of approximately 56%. These figures are presented as estimates for 2027 and are subject to the risks and uncertainties outlined in the filing.

The document contains extensive forward-looking statements protected by the safe harbor provisions of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Third Coast cautions that these statements are not guarantees of future performance and are based on current expectations and assumptions that are inherently uncertain. Factors that could cause actual results to differ materially include the potential for termination of the definitive merger agreement, the outcome of legal proceedings, and the possibility that regulatory or shareholder approvals are not received on time.

Additional risks cited include the potential for integration delays or increased costs, reputational risk among customers and employees, and dilution from the issuance of additional common stock by Third Coast. The filing also notes general competitive, economic, and market conditions, as well as major catastrophes such as natural disasters or infectious disease outbreaks, as factors that may affect future results. Third Coast directs investors to its Annual Report on Form 10-K for the year ended December 31, 2025, for a discussion of additional risk factors.

The presentation also references non-GAAP financial measures, including Tangible Common Equity and Return on Average Tangible Common Equity. Management advises that these measures should not be considered in isolation or as a substitute for GAAP-compliant financial measures. The company states it does not undertake any obligation to update forward-looking statements publicly, whether due to new information or future developments.
