Non-GAAP Financial Measures

Management has presented non-GAAP financial measures in this discussion and analysis because it believes that they provide useful information to assess trends in our core operations and to facilitate the comparison of our performance with our peers. However, these non-GAAP financial measures are supplemental to, and not a substitute for, any analysis based on GAAP. The most directly comparable GAAP financial measures are presented with equal or greater prominence. For a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP measures, see the tables below. Because not all companies use the same calculations, our presentation may not be comparable to other similarly titled measures as calculated by other companies.

Adjusted revenue, diluted adjusted earnings per share and adjusted efficiency ratio are non-GAAP financial measures. To calculate adjusted revenue, diluted adjusted earnings per share and adjusted efficiency ratio, we make adjustments to our GAAP revenues and expenses as reported on our Consolidated Statements of Operations. Management believes that these non-GAAP financial measures provide information to investors that is useful in evaluating the operating performance and trends of financial services companies, including the Company, by excluding certain items that Management considers not reflective of core operating performance. The following tables set forth reconciliations of these non-GAAP financial measures (dollars in thousands, except share and per share data):

The ratio of tangible common shareholders’ equity to tangible assets is a non-GAAP financial measure. We calculate tangible common equity by excluding goodwill and other intangible assets from shareholders’ equity. We calculate tangible assets by excluding the balance of goodwill and other intangible assets from total assets. Bank regulatory capital measures also exclude goodwill and certain intangible assets; however, tangible common equity and tangible assets as presented here are non-GAAP financial measures and should not be considered substitutes for regulatory capital ratios. The following table sets forth the reconciliation of tangible equity and tangible assets (dollars in thousands, except share and per share data).

Critical Accounting Estimates

The preparation of financial statements in conformity with GAAP requires Management to make estimates, assumptions and judgments that affect amounts reported in the consolidated financial statements. These estimates, assumptions, and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, actual results could differ from the estimates, assumptions, and judgments reflected in the financial statements. Management believes the following estimates require difficult, subjective or complex judgments and, therefore, Management considers the following to be critical accounting estimates.

Allowance for Credit Losses: The allowance for credit losses reflects Management’s evaluation of our loans and unfunded loan commitments along with their estimated loss potential, as well as the risk inherent in various components of the portfolio. Significant judgments and assumptions are applied in estimating the allowance for credit losses. These judgments, assumptions and estimates are susceptible to significant changes based on the current environment. Among the material estimates required to establish the allowance for credit losses are a reasonable and supportable forecast; a reasonable and supportable forecast period and the reversion period; value of collateral; strength of guarantors; the amount and timing of future cash flows for loans individually evaluated; and determination of the qualitative loss factors.

Management estimates the allowance for credit losses using relevant information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The allowance for credit losses is maintained at a level sufficient to provide for expected credit losses over the life of the asset based on evaluating historical credit loss experience and making adjustments to historical loss information for differences in the specific risk characteristics in the current portfolio. These factors include, among others, changes in the size and composition of the portfolio, differences in underwriting standards, delinquency rates, actual loss experience and current economic conditions.

Management considers various economic scenarios and forecasts to arrive at the estimate that most reflects Management’s expectations of future conditions. As of December 31, 2025, Management used a baseline forecast to estimate the allowance for credit losses. The selection of a more optimistic or pessimistic economic forecast would result in a lower or higher allowance for credit losses. While there are multiple economic forecast scenarios available, the use of a protracted slump economic forecast would have increased the allowance for credit losses - loans by approximately 10% as of December 31, 2025, where the use of a stronger near-term growth economic forecast would have resulted in a negligible decrease in the allowance for credit losses - loans as of December 31, 2025.

Management uses a scale to assign qualitative and environmental (QE) factor adjustments based on the level of estimated impact which requires a significant amount of judgment. Some QE factors impact all loan segments equally while others may impact some loan segments more or less than others. If Management’s judgment was different for a QE factor that impacts all loan segments equally, a five basis-point change in this QE factor would increase or decrease the allowance for credit losses by approximately 4% as of December 31, 2025.

Fair Value Accounting and Measurement: We use fair value measurements to record certain financial assets and liabilities at their estimated fair value. A hierarchical disclosure framework associated with the level of pricing observability is utilized in measuring financial instruments at fair value. The degree of judgment utilized in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Financial instruments with readily available active quoted prices or for which fair value can be measured from actively quoted prices generally will have a higher degree of pricing observability and a lesser degree of judgment utilized in measuring fair value. Conversely, financial instruments rarely traded or not quoted will generally have little or no pricing observability and a higher degree of judgment utilized in measuring fair value. Determining the fair value of financial instruments with unobservable inputs requires a significant amount of judgment. This includes the discount rate used to fair value our trust preferred securities and junior subordinated debentures. A 25 basis-point increase or decrease in the discount rate used to calculate the fair value of our trust preferred securities would result in a $628,000 decrease or increase in the reported fair value as of December 31, 2025, with an offsetting adjustment to our accumulated other comprehensive income. A 25 basis-point increase or decrease in the discount rate used to calculate the fair value of our junior subordinated debentures would result in a $1.6 million decrease or increase in the reported fair value as of December 31, 2025, with an offsetting adjustment to our accumulated other comprehensive income.
