OP Bancorp

Note 12 —Regulatory Capital Matters

The Bank is subject to certain risk-based capital and leverage ratio requirements under the U.S. Basel III capital rules administered by the federal and state banking agencies. Failure to be well-capitalized or to meet minimum capital requirements could result in certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have an adverse material effect on the Company's operations or financial condition. The Basel III capital rules also require the Bank to maintain a capital conservation buffer of 2.50% above the minimum risk-based capital ratios in order to absorb losses during periods of economic stress. Banking institutions with a ratio of common equity tier 1 capital to risk-weighted assets above the minimum but below the capital conservation buffer will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall. As of both June 30, 2026 and December 31, 2025, the Bank met all applicable capital adequacy requirements.

The following table presents the regulatory capital amounts and ratios for the Company and the Bank as of dates indicated:
