The Company and Bank are subject to various regulatory capital requirements administered by the FRB and the OCC. Failure to meet minimum capital requirements can result in mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements.

The Company and Bank are required to maintain certain levels of capital based on risk-adjusted assets. These capital requirements represent quantitative measures of their assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Company and Bank's capital classification is also subject to qualitative judgments by our regulators about components, risk weightings and other factors. The quantitative measures established to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios of total capital, Tier 1 capital, and common equity Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets, or the leverage ratio. These requirements apply to the Company on a consolidated basis.

Under the current requirements, banking organizations must have a minimum total risk-based capital ratio of 8.0%, a minimum Tier 1 risk-based capital ratio of 6.0%, a minimum common equity Tier 1 risk-based capital ratio of 4.5%, and a minimum leverage ratio of 4.0% in order to be "adequately capitalized." In addition to these requirements, banking organizations must maintain a capital conservation buffer consisting of common Tier 1 equity in an amount above the minimum risk-based capital requirements for "adequately capitalized" institutions equal to 2.5% of total risk-weighted assets, resulting in a requirement for the Company and the Bank effectively to maintain common equity Tier 1, Tier 1 and total capital ratios of 7.0%, 8.5% and 10.5%, respectively. The Company and the Bank must maintain the capital conservation buffer to avoid restrictions on the ability to pay dividends, pay discretionary bonuses and to engage in share repurchases based on the amount of the shortfall and the institution's "eligible retained income" (that is, the greater of (i) net income for the preceding four quarters, net of distributions and associated tax effects not reflected in net income and (ii) average net income over the preceding four quarters).

The Company and Bank's risk-based capital ratios exceeded regulatory requirements, including the capital conservation buffer, as of June 30, 2025 and December 31, 2024, and the Bank's capital ratios met the requirements for it to be considered "well capitalized" under prompt corrective action provisions for each period. There were no changes to the Company or Bank's capital ratios that occurred subsequent to June 30, 2025 that would change the Company or Bank's regulatory capital categorization. The following table presents the Company and Bank's regulatory capital ratios at the periods indicated:

In 2006 and 2008, the Company issued $44.3 million of junior subordinated debentures in connection with the issuance of trust preferred securities. In the first quarter of 2025, the Company assumed, as part of the Northway acquisition, two additional tranches of junior subordinated debentures totaling $20.6 million, which were subject to fair value purchase accounting at the acquisition date. Refer to Note 7 for additional information regarding the junior subordinated debentures assumed in connection with the Northway acquisition. Although the junior subordinated debentures are recorded as liabilities on the Company's

consolidated statements of condition, the Company is permitted, in accordance with applicable regulation, to include the debentures within its calculation of risk-based capital, subject to certain limits. As of June 30, 2025 and December 31, 2024, $63.0 million and $43.0 million, respectively, of the junior subordinated debentures were included in Tier 1 and total risk-based capital for the Company.

The Company and Bank's regulatory capital and risk-weighted assets fluctuate due to normal business, including profits and losses generated by the Company and Bank as well as changes to their asset mix. Of particular significance are changes within the Company and Bank's loan portfolio mix due to the differences in regulatory risk-weighting between retail and commercial loans. Furthermore, the Company and Bank's regulatory capital and risk-weighted assets are subject to change due to changes in GAAP and regulatory capital standards. The Company and Bank proactively monitor their regulatory capital and risk-weighted assets, and the impact of changes to their asset mix, and the impact of proposed and pending changes as a result of new and/or amended GAAP standards and regulatory changes.
