Regulatory Capital [Abstract] |
Regulatory Capital | Note 10 -- Regulatory Capital The Company is subject to various regulatory capital requirements administered by the federal banking agencies. Bank holding companies follow minimum regulatory requirements established by the Board of Governors of the Federal Reserve System (“Federal Reserve System”), First Mid Bank follows similar minimum regulatory requirements established for banks by the Office of the Comptroller of the Currency (“OCC”) and the Federal Deposit Insurance Corporation, as applicable. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary action by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Quantitative measures established by regulatory capital standards to ensure capital adequacy require the Company and its subsidiary bank to maintain minimum capital amounts and ratios (set forth in the table below). Management believes that, as of September 30, 2025 and December 31, 2024, the Company and First Mid Bank, as applicable, met all capital adequacy requirements. To be categorized as well-capitalized, total risk-based capital, Tier 1 risk-based capital, common equity Tier 1 risk-based capital and Tier 1 leverage ratios must be maintained as set forth in the following table (dollars in thousands):
