Allowance for Credit Losses The allowance for credit losses is maintained at a level that management considers appropriate to provide for the Company’s current estimate of expected lifetime credit losses on loans measured at amortized cost. The allowance is increased by providing for credit losses through a charge to expense and by credits for recoveries of loans previously charged-off and is reduced by loans being charged-off.

In accordance with its Allowance for Credit Losses Program, the Company uses the Current Expected Credit Losses (or “CECL”) model methodology to estimate credit losses for financial assets on a collective basis for loans sharing similar risk characteristics using a quantitative model combined with an assessment of certain qualitative factors designed to address forecast risk and model risk inherent in the quantitative model output. The model estimates expected credit losses using loan level data over the contractual life of the exposure, which is adjusted for estimated prepayments. Economic forecasts are incorporated into the estimate over a reasonable and supportable forecast period of 12 months, beyond which is a reversion to the Company’s historical long-run average over a period of six months. The Company’s qualitative assessment is structured based upon nine qualitative risk factors impacting the expected risk of loss within the loan portfolio, with an additional factor designed to capture model imprecision. Loans that do not share similar risk characteristics with any pools of assets are subject to individual assessment and are removed from the collectively assessed pools to avoid double counting. For the loans that will be individually assessed, the Company uses either a discounted cash flow approach or a fair value of collateral approach. The latter approach is used for loans deemed to be collateral dependent or when foreclosure is probable.

Management’s allowance for credit loss estimate inco rporates an economic forecast over a reasonable and supportable period of 12 months. As of September 30, 2025, management utilized the Moody’s Baseline forecast to estimate the effect of anticipated current and future economic conditions on the Company’s allowance for credit losses. This scenario selected by management assumes that general economic conditions will reflect a slight increase in momentum in the near term, that monetary policy will be impacted by a gradual reduction in Federal Reserve policy rates, and that progress toward inflation will be slowed as a result of changes in international trade policies. Additionally, the allowance for credit losses is qualitatively adjusted on a quarterly basis in order to ensure coverage for relationships that are deemed to be more at risk within certain industries, specific collateral types, or other specific characteristics that may be highly impacted by the current economic environment.

The allowance for credit losses of $190.5 million at September 30,2025 represents an increase of $20.5 million, or 12.1% compared to December 31, 2024, driven primarily by $43.5 million in initial allowance reserves recorded on the acquired Enterprise loan portfolio, including $34.5 million and $9.0 million attributable to non-PCD and PCD loans, respectively.
