Operating Results

Net Income and Earnings Per Common Share

Net income totaled $22.0 million for the second quarter of 2026, compared to $16.4 million for the first quarter of 2026 and $16.7 million for the second quarter of 2025. Net income available to common shareholders totaled $20.8 million for the second quarter of 2026, compared to $15.2 million for the first quarter of 2026 and $15.6 million for the second quarter of 2025. The quarter-over-quarter increase from the first quarter of 2026 was primarily due to an increase in net interest income and the gain on sale of factored receivables. Dividends on our Series A Convertible Non-Cumulative Preferred Stock (“Series A Preferred Stock”) totaled $1.2 million for each of the quarters ended June 30, 2026, March 31, 2026 and June 30, 2025.

Basic and diluted earnings per common share were $1.25 per share and $1.08 per share, respectively, in the second quarter of 2026, compared to $1.03 per share and $0.88 per share, respectively, in the first quarter of 2026 and $1.12 per share and $0.96 per share, respectively, in the second quarter of 2025.

Net Interest Margin and Net Interest Income

The net interest margin for the second quarter of 2026 was 3.83%, compared to 3.67% for the first quarter of 2026 and 4.22% for the second quarter of 2025. The yield on loans for the second quarter of 2026 was 7.06%, compared to 7.01% for the first quarter of 2026 and 7.95% for the second quarter of 2025. The cost of interest-bearing deposits for the second quarter of 2026 was 3.41%, compared to 3.53% for the first quarter of 2026 and 4.00% for the second quarter of 2025.

Net interest income totaled $60.3 million for the second quarter of 2026, an increase of 12.4% from $53.6 million for the first quarter of 2026 and an increase of 22.1% from $49.4 million for the second quarter of 2025. Interest income totaled $106.0 million for the second quarter of 2026, an increase of 8.8% from $97.4 million for the first quarter of 2026 and an increase of 19.5% from $88.7 million for the second quarter of 2025. The quarter-over-quarter increase from the first quarter of 2026 in interest income primarily resulted from an increase in loans. Interest expense was $45.7 million for the second quarter of 2026, an increase of $2.0 million, or 4.5%, from $43.7 million for the first quarter of 2026 and an increase of $6.4 million, or 16.4%, from $39.3 million for the second quarter of 2025, primarily resulting from an increase in interest-bearing demand deposits slightly offset by a reduction in rates paid on interest-bearing demand deposits.

Noninterest Income and Noninterest Expense

Noninterest income totaled $7.7 million for the second quarter of 2026, compared to $4.0 million for the first quarter of 2026 and $2.7 million for the second quarter of 2025. The quarter-over-quarter increase from the first quarter of 2026 in noninterest income was primarily due to the gain on sale of factored receivables during the second quarter of 2026.

Noninterest expense remained flat at $38.4 million for the second quarter of 2026, compared to $38.1 million for the first quarter of 2026 and $28.8 million for the second quarter of 2025. At June 30, 2026, the number of employees decreased to 504, compared to 514 at March 31, 2026.

The efficiency ratio was 56.51% for the second quarter of 2026, compared to 66.06% for the first quarter of 2026 and 55.45% for the second quarter of 2025.

Balance Sheet Highlights

Loan Portfolio and Composition

For the quarter ended June 30, 2026, gross loans increased to $5.44 billion, an increase of $185.0 million, or 3.5%, from $5.25 billion as of March 31, 2026, and an increase of $1.36 billion, or 33.3%, from $4.08 billion as of June 30, 2025. Commercial and industrial loans accounted for the majority of the loan growth for the second quarter of 2026, with commercial and industrial loans increasing $186.7 million from the first quarter of 2026.

Asset Quality

Nonperforming loans at June 30, 2026 were $30.0 million, compared to $35.6 million at March 31, 2026 and $20.1 million at June 30, 2025. The decrease in nonperforming loans during the second quarter of 2026 was primarily due to the transfer of a $17.1 million loan to other real estate owned, offset by the placement on nonaccrual of three relationships totaling $10.1 million and an increase of $2.1 million in loans over 90 days past due and still accruing. As of June 30, 2026, the nonperforming loans to total loans ratio was 0.55%, compared to 0.68% as of March 31, 2026 and 0.49% as of June 30, 2025.

The provision for credit loss recorded for the second quarter of 2026 was $2.1 million, and the allowance for credit losses of $53.6 million represented 0.99% of the $5.44 billion in gross loans outstanding as of June 30, 2026. The provision for credit loss recorded for the first quarter of 2026 was $580,000, and the allowance for credit losses of $51.5 million represented 0.98% of the $5.25 billion in gross loans outstanding as of March 31, 2026.

The Company recorded net recoveries of $150,000 and net charge-offs of $2.4 million for the three months ended June 30, 2026 and June 30, 2025, respectively.

Deposits and Composition

Deposits totaled $5.86 billion as of June 30, 2026, an increase of 2.5% from $5.72 billion as of March 31, 2026, and an increase of 36.8% from $4.28 billion as of June 30, 2025. Noninterest-bearing demand deposits increased from $577.2 million as of March 31, 2026, to $642.7 million as of June 30, 2026 and represented 11.0% and 10.1% of total deposits as of June 30, 2026 and March 31, 2026, respectively. As of June 30, 2026, interest-bearing demand deposits increased $44.2 million, or 1.0%, time deposits increased $28.1 million, or 3.4%, and savings accounts increased $2.5 million, or 9.9%, respectively, from March 31, 2026.

The average cost of deposits was 3.05% for the second quarter of 2026, representing a 12-basis point decrease from the first quarter of 2026 and a 54-basis point decrease from the second quarter of 2025. The decreases were primarily due to the reduction in rates paid on interest-bearing demand deposits.

This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that are subject to risks and uncertainties and are made pursuant to the safe harbor provisions of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements reflect our current views with respect to, among other things, future events and our financial performance. These statements are often, but not always, made through the use of words or phrases such as

3

“may,” “should,” “could,” “predict,” “potential,” “believe,” “looking ahead,” “will likely result,” “expect,” “continue,” “will,” “anticipate,” “seek,” “estimate,” “intend,” “plan,” “projection,” “would” and “outlook,” or the negative version of those words or other comparable words or phrases of a future or forward-looking nature. These forward-looking statements are not historical facts, and are based on current expectations, estimates and projections about our industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions and uncertainties that are difficult to predict. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. There are or will be important factors that could cause our actual results to differ materially from those indicated in these forward-looking statements, including, but not limited to, the following: interest rate risk and fluctuations in interest rates; market conditions and economic trends generally and in the banking industry; our ability to maintain important deposit relationships; our ability to grow or maintain our deposit base; our ability to implement our expansion strategy; our ability to pay dividends on our Series A Preferred Stock; credit risk associated with our business; economic conditions affecting the real estate market; prepayment risks associated with commercial real estate loans; liquidity risks in the securitization market; operational risks related to the administration of securitized assets; changes in key management personnel; the risk that the benefits from the transaction between Third Coast and Keystone Bancshares, Inc. (“Keystone”) may not be fully realized or may take longer to realize than expected, including as a result of changes in, or problems arising from, general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which Third Coast and Keystone operate; the risk that the integration of each party’s operations will be materially delayed or will be more costly or difficult than expected or that the parties are otherwise unable to successfully integrate each party’s businesses into the other’s businesses; the possibility that the completion of the transaction may be more expensive than anticipated, including as a result of unexpected factors or events; reputational risk and potential adverse reactions of Third Coast’s or Keystone’s customers, suppliers, employees or other business partners, including those resulting from the completion of the transaction; the dilution caused by Third Coast’s issuance of additional shares of its common stock in connection with the transaction; and other factors that may affect future results of Third Coast and Keystone including changes in asset quality and credit risk, the inability to sustain revenue and earnings growth, changes in interest rates and capital markets, inflation, customer borrowing, repayment, investment and deposit practices, the impact, extent and timing of technological changes, capital management activities and other actions of the Board of Governors of the Federal Reserve System and legislative and regulatory actions and reforms. For a discussion of additional factors that could cause our actual results to differ materially from those described in the forward-looking statements, please see the risk factors discussed in our Annual Report on Form 10-K for the year ended December 31, 2025 filed with the U.S. Securities and Exchange Commission (the “SEC”), and our other filings with the SEC.

The foregoing factors should not be construed as exhaustive and should be read together with the other cautionary statements included in this press release. If one or more events related to these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may differ materially from what we anticipate. Accordingly, you should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made, and we do not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise. New factors emerge from time to time, and it is not possible for us to predict which will arise. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

Third Coast Bancshares, Inc. and Subsidiary

GAAP Reconciliation and Management's Explanation of Non-GAAP Financial Measures

(unaudited)

Our accounting and reporting policies conform to GAAP (generally accepted accounting principles) and the prevailing practices in the banking industry. However, we also evaluate our performance based on certain additional financial measures discussed in this earnings release as being non-GAAP financial measures. Specifically, we review Tangible Common Equity, Tangible Book Value Per Common Share, Tangible Common Equity to Tangible Assets, and Return on Average Tangible Common Equity for internal planning and forecasting purposes. We classify a financial measure as a non-GAAP financial measure if that financial measure excludes or includes amounts, or is subject to adjustments that have the effect of excluding or including amounts, that are not included or excluded, as the case may be, in the most directly comparable measure calculated and presented in accordance with GAAP as in effect from time to time in the United States in our statements of income, balance sheets or statements of cash flows. Non-GAAP financial measures do not include operating and other statistical measures or ratios, or statistical measures calculated using exclusively financial measures calculated in accordance with GAAP.

The non-GAAP financial measures that we discuss in this earnings release should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Moreover, the manner in which we calculate the non-GAAP financial measures that we discuss in this earnings release may differ from that of other companies reporting measures with similar names. It is important to understand how other banking organizations calculate their financial measures with names similar to the non-GAAP financial measures we have discussed in this earnings release when comparing such non-GAAP financial measures.

Management believes the following non-GAAP financial measures assist investors in understanding the financial condition of the company:

•

Tangible Common Equity. The most directly comparable GAAP financial measure for tangible common equity is total shareholders’ equity. We believe that this measure is important to many investors in the marketplace who are interested in the relative changes from period to period of tangible common equity.

•

Tangible Book Value Per Common Share. The most directly comparable GAAP financial measure for tangible book value per common share is book value per common share. We believe that the tangible book value per common share measure is important to many investors in the marketplace who are interested in changes from period to period in book value per common share exclusive of changes in intangible assets. Goodwill and other intangible assets have the effect of increasing total book value while not increasing our tangible book value.

•

Tangible Common Equity to Tangible Assets. The most directly comparable GAAP financial measure for tangible common equity is total shareholders’ equity, the most directly comparable GAAP financial measure for tangible assets is total assets, and the most directly comparable GAAP financial measure for tangible common equity to tangible assets is total shareholders’ equity to total assets. We believe that this measure is important to many investors in the marketplace who are interested in the relative changes from period to period of tangible common equity to tangible assets, each exclusive of changes in intangible assets. Goodwill and other intangible assets have the effect of increasing both total shareholders’ equity and assets while not increasing our tangible common equity or tangible assets.

•

Return on Average Tangible Common Equity. The most directly comparable GAAP financial measure for average tangible common equity is average shareholders' equity, and the most directly comparable GAAP financial measure for return on average tangible common equity is return on average common equity. We believe that this measure is important to many investors in the marketplace who are interested in the relative changes from period to period of return on average tangible common equity, exclusive of changes in intangible assets. Goodwill and other intangible assets have the effect of increasing average shareholders’ equity while not increasing our tangible common equity.

The calculations of these non-GAAP financial measures are as follows:

THIRD COASTBANCSHARES, INC. NYSE & NYSE Texas: TCBX Investor Presentation July 2026 © 2026 Third Coast Bancshares, Inc. Exhibit 99.2

02 DISCLAIMER Forward-Looking Statements This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that are subject to risks and uncertainties and are made pursuant to the safe harbor provisions of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements reflect the current views of Third Coast Bancshares, Inc. (the “Company,” “Third Coast,” “we,” “us,” or “our”) with respect to, among other things, future events and our financial performance. These statements are often, but not always, made through the use of words or phrases such as “may,” “should,” “could,” “predict,” “potential,” “believe,” “looking ahead,” “will likely result,” “expect,” “continue,” “will,” “anticipate,” “seek,” “estimate,” “intend,” “plan,” “projection,” “would” and “outlook,” or the negative version of those words or other comparable words or phrases of a future or forward-looking nature. These forward-looking statements are not historical facts, and are based on current expectations, estimates and projections about our industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions and uncertainties that are difficult to predict. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. There are or will be important factors that could cause our actual results to differ materially from those indicated in these forward-looking statements, including, but not limited to, the following: interest rate risk and fluctuations in interest rates; market conditions and economic trends generally and in the banking industry; our ability to maintain important deposit relationships; our ability to grow or maintain our deposit base; our ability to implement our expansion strategy; our ability to pay dividends on our Series A Preferred Stock; credit risk associated with our business; economic conditions affecting the real estate market; prepayment risks associated with commercial real estate loans; liquidity risks in the securitization market; operational risks related to the administration of securitized assets; changes in key management personnel; the risk that the benefits from the transaction between Third Coast and Keystone Bancshares, Inc (“Keystone”) may not be fully realized or may take longer to realize than expected, including as a result of changes in, or problems arising from, general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which Third Coast and Keystone operate; the risk that the integration of each party’s operations will be materially delayed or will be more costly or difficult than expected or that the parties are otherwise unable to successfully integrate each party’s businesses into the other’s businesses; the possibility that the completion of the transaction may be more expensive than anticipated, including as a result of unexpected factors or events; reputational risk and potential adverse reactions of Third Coast’s or Keystone’s customers, suppliers, employees or other business partners, including those resulting from the announcement or completion of the transaction; the dilution caused by Third Coast’s issuance of additional shares of its common stock in connection with the transaction; and other factors that may affect future results of Third Coast and Keystone including changes in asset quality and credit risk, the inability to sustain revenue and earnings growth, changes in interest rates and capital markets, inflation, customer borrowing, repayment, investment and deposit practices, the impact, extent and timing of technological changes, capital management activities and other actions of the Board of Governors of the Federal Reserve System and legislative and regulatory actions and reforms. For a discussion of additional factors that could cause our actual results to differ materially from those described in the forward-looking statements, please see the risk factors discussed in our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the U.S. Securities and Exchange Commission (the “SEC”), and our other filings with the SEC. The foregoing factors should not be construed as exhaustive and should be read together with the other cautionary statements included in this presentation. If one or more events related to these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may differ materially from what we anticipate. Accordingly, you should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made, and we do not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise. New factors emerge from time to time, and it is not possible for us to predict which will arise. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. NON-GAAP FINANCIAL MEASURES This presentation contains non-GAAP financial measures, including Tangible Common Equity, Tangible Book Value Per Common Share, Tangible Common Equity to Tangible Assets and Return on Average Tangible Common Equity. The non-GAAP financial measures that we discuss in this presentation should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. A reconciliation of the non-GAAP financial measures used in this presentation to the most directly comparable GAAP measures is provided in the Appendix to this presentation. 
