Note 17 – Shareholders’ Equity

Regulatory Capital

Trustmark and TNB are subject to minimum risk-based capital and leverage capital requirements, as described in the section captioned “Capital Adequacy” included in Part I. Item 1. – Business of this report, which are administered by the federal bank regulatory agencies. These capital requirements, as defined by federal regulations, involve quantitative and qualitative measures of assets, liabilities and

certain off-balance sheet instruments. Trustmark’s and TNB’s minimum risk-based capital requirements include a capital conservation buffer of 2.5%. Accumulated other comprehensive income (loss), net of tax, is not included in computing regulatory capital. Trustmark elected the five-year phase-in transition period (through December 31, 2024) related to adopting FASB ASU 2016-13 for regulatory capital purposes. Failure to meet minimum capital requirements can result in certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the financial statements of Trustmark and TNB and limit Trustmark’s and TNB’s ability to pay dividends. At December 31, 2023, Trustmark and TNB exceeded all applicable minimum capital standards. In addition, Trustmark and TNB met applicable regulatory guidelines to be considered well-capitalized at December 31, 2023. To be categorized in this manner, Trustmark and TNB maintained minimum common equity Tier 1 risk-based capital, Tier 1 risk-based capital, total risk-based capital and Tier 1 leverage ratios as set forth in the accompanying table, and were not subject to any written agreement, order or capital directive, or prompt corrective action directive issued by their primary federal regulators to meet and maintain a specific capital level for any capital measures. There are no significant conditions or events that have occurred since December 31, 2023, which Management believes have affected Trustmark’s or TNB’s present classification.

The following table provides Trustmark’s and TNB’s actual regulatory capital amounts and ratios under regulatory capital standards in effect at December 31, 2023 and 2022 ($ in thousands):
