OP Bancorp

We are subject to various regulatory capital requirements administered by the federal and state banking regulators, although, as a “smaller bank holding company,” we are not subject to most of these standards at the holding company level. These standards are, however, applicable to the Bank, and failure to meet regulatory capital requirements may result in certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our Consolidated Financial Statements. Under capital adequacy guidelines and the regulatory framework for “prompt corrective action”, the Bank must meet specific capital guidelines that involve quantitative measures of our assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting policies. The capital amounts and classifications are subject to qualitative judgments by the federal banking regulators regarding components, risk weightings and other factors. Qualitative measures established by regulation to ensure capital adequacy required us to maintain minimum amounts and various ratios of CET1 capital, Tier 1 capital and total capital to risk-weighted assets and of Tier 1 capital to average consolidated assets, referred to as the “leverage ratio.”

The table below summarizes the capital requirements applicable to us and the Bank in order to be considered “well-capitalized” from a regulatory perspective, as well as our and the Bank’s capital ratios as of March 31, 2026 and December 31, 2025. The Bank exceeded all regulatory capital requirements under the Basel III Capital Rules and were considered to be “well-capitalized” as of the dates reflected in the table below. As of March 31, 2026, the FDIC categorized us as well-capitalized under the prompt corrective action framework. There have been no conditions or events since March 31, 2026 that management believes would change this classification.
