Third Quarter 2024 Asset Quality Non-Performing Assets ($MM) Decrease in NPAs was primarily attributed to an $8.2 million sale of a nonaccrual C&I loan in the Puerto Rico region Inflows to nonaccrual loans held for investment were $38.7 million, a decrease of $5.3 million when compared to the prior quarter, mostly related to decreases in inflows to nonaccrual commercial and construction loans of $17.1 million primarily related to the $16.5 million Puerto Rico commercial relationship that migrated to nonaccrual in 2Q 2024, partially offset by an increase in nonaccrual consumer loans inflows of $10.5 million Loans in early delinquency (i.e., 30-89 days past due accruing loans) amounted to $143.4 million, a decrease of $4.0 million vs. 2Q 2024, mostly related to a $7.9 million decrease in consumer loans, mainly in the auto loans and finance leases portfolio, partially offset by an increase of $4.3 million in commercial and construction loans Total non-performing assets decreased by $7.8 million to $119.1 million or 0.63% of total assets 0.70% 3Q23 0.67% 4Q23 0.69% 1Q24 0.67% 2Q24 $89 0.63% 3Q24 $130 $126 $130 $127 $119 Repossessed Assets and Other Loans HFI NPAs/Assets $2 3Q23 $2 4Q23 $1 1Q24 $5 2Q24 $4 3Q24 $130 $126 $130 $127 $119 Repossessed Assets and Other Consumer Residential Construction Commercial 10

Third Quarter 2024 Appendix - Use of Non-GAAP Financial Measures Basis of Presentation: Use of Non-GAAP Financial Measures This presentation contains non-GAAP financial measures. Non-GAAP financial measures are used when management believes that the presentation of these non-GAAP financial measures enhances the ability of analysts and investors to analyze trends in the Corporation’s business and understand the performance of the Corporation. Where non-GAAP financial measures are used, the most comparable GAAP financial measure, as well as the reconciliation of the non-GAAP financial measure to the most comparable GAAP financial measure, can be found in the text or in the attached tables to this earnings presentation. Any analysis of these non-GAAP financial measures should be used only in conjunction with results presented in accordance with GAAP. Tangible Common Equity Ratio and Tangible Book Value per Common Share The tangible common equity ratio and tangible book value per common share are non-GAAP financial measures that management believes are generally used by the financial community to evaluate capital adequacy. Tangible common equity is total common equity less goodwill and other intangibles. Tangible assets are total assets less goodwill and other intangibles. Management and many stock analysts use the tangible common equity ratio and tangible book value per common share in conjunction with more traditional bank capital ratios to compare the capital adequacy of banking organizations with significant amounts of goodwill or other intangible assets, typically stemming from the use of the purchase method of accounting for mergers and acquisitions. Accordingly, the Corporation believes that disclosure of these financial measures may be useful to investors. Neither tangible common equity nor tangible assets, or the related measures, should be considered in isolation or as a substitute for stockholders’ equity, total assets, or any other measure calculated in accordance with GAAP. Moreover, the way the Corporation calculates its tangible common equity, tangible assets, and any other related measures may differ from that of other companies reporting measures with similar names. 16

Adjusted Pre-Tax, Pre-Provision Income Adjusted pre-tax, pre-provision income is a non-GAAP performance metric that management uses and believes that investors may find useful in analyzing underlying performance trends, particularly in times of economic stress, including as a result of natural catastrophes or health epidemies. Adjusted pre-tax, pre-provision income, as defined by management, represents income before income taxes adjusted to exclude the provision for credit losses expense, as well as certain items that management believes are not reflective of core operating performance. 17

Adjusted Return on Average Common Equity Ratio Net income divided by adjusted average common equity, which is average total common equity, after exclusion of average net unrealized losses on available-for-sale debt securities recognized as part of accumulated other comprehensive loss. 18
