HERITAGE FINANCIAL CORP /WA/

Regulatory Requirements

The Company is a bank holding company under the supervision of the Federal Reserve. Bank holding companies are subject to capital adequacy requirements of the Federal Reserve under the Bank Holding Company Act of 1956, as amended, and the regulations of the Federal Reserve. The Bank is a federally insured institution and thereby is subject to the capital requirements established by the FDIC. The Federal Reserve capital requirements generally parallel the FDIC requirements. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect in the unaudited Condensed Consolidated Financial Statements and operations. Additionally, the Company and the Bank are required to maintain a capital conservation buffer of common equity Tier 1 capital above 2.5% to avoid restrictions on certain activities including payment of dividends, stock repurchases and discretionary bonuses to executive officers. Management believes that, as of September 30, 2025, the Company and the Bank met all capital adequacy requirements to which they are subject.

As of September 30, 2025 and December 31, 2024, the most recent regulatory notifications categorized the Bank as well-capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bank's categories.

The following table summarizes the Company's consolidated and the Bank's actual capital ratios compared to the regulatory "adequately capitalized" capital ratio and the regulatory minimum capital ratio needed to qualify as a "well capitalized" institution, as calculated under regulatory guideline at the dates presented:

(1)The ratios to meet the requirements to be deemed “well-capitalized” under prompt corrective action regulations are only applicable to the Bank. However, the Company manages its capital position as if the requirements apply to the consolidated Company and has presented the ratios as if they also applied on a consolidated basis.
