Third Quarter 2025 Profitability Dynamics Net Interest Income ($MM) 4.25% 3Q24 4.33% 4Q24 4.52% 1Q25 4.56% 2Q25 4.57% 3Q25 Net Interest Income ($) Net Interest Margin (GAAP %) Net interest income amounted to $217.9 million, an increase of $2.0 million vs. the prior quarter, which includes $1.3 million associated with the effect of one additional day in the quarter. The increase primarily reflects: A $4.6 million increase in interest income on total loans due to higher average balances and the effect of one additional day in the quarter and a $2.1 million increase in interest income from investment securities resulting from an improvement in yields which was offset by a $2.2 million decrease in interest income from a reduction in cash balances A $2.5 million increase in interest expense mostly due to higher average balances of both brokered and non-brokered time deposits, an increase of 6 basis points in the cost of funds and the effect of one additional day in the quarter Net interest margin increased during the quarter by 1 basis point to 4.57%, mostly reflecting the change in asset mix associated to the deployment of cash flows from lower yielding securities to higher yielding interest-earning assets which was almost entirely offset by the increase in the cost of funds of non-maturity public funds and higher balances of time deposits Key Highlights Evolution of Loan Yields and Cost of Funds(1) (1) Cost of funds include cost of all interest-bearing deposits, non-interest-bearing deposits, and wholesale funding 3Q24 4Q24 1Q25 2Q25 3Q25 6.14% 6.10% 6.22% 6.18% 6.11% Loan Yields Cost of Funds

Third Quarter 2025 Asset Quality Non-Performing Assets ($MM) Decrease in non-performing assets was driven by a $3.8 million decrease in nonaccrual loans and a $5.1 million reduction in OREO balances mainly due to the $2.8 million valuation adjustment recorded in a commercial OREO in the Virgin Islands Inflows to non-accrual loans held for investment were $32.2 million, a decrease of $2.2 million when compared to the prior quarter, mostly related to a decrease of $4.9 million in inflows of commercial and construction loans and a reduction of $1.8 million in inflows of nonaccrual residential loans, partially offset by a $4.5 million increase in consumer inflows to nonaccrual Loans in early delinquency (i.e., 30-89 days past due accruing loans) amounted to $142.9 million, an increase of $8.9 million vs. 2Q 2025, mostly related to a net increase of $7.6 million in commercial loans, particularly a $6.0 million past due C&I loan in Florida Total non-performing assets decreased by $8.6 million to $119.4 million or 0.62% of total assets 0.63% 3Q24 0.61% 4Q24 0.68% 1Q25 0.68% 2Q25 $119.1 $118.3 $129.4 $128.0 3Q25 $119.4 0.62% Repossessed Assets and Other Loans HFI NPAs/Assets $4.0 3Q24 $1.4 4Q24 $1.4 1Q25 $5.7 2Q25 $119.0 $118.3 $129.4 $128.0 3Q25 $119.4 $5.6 Repossessed Assets and Other Consumer Residential Construction Commercial

Third Quarter 2025 ACL and Capital Total stockholders’ equity amounted to $1.9 billion, an increase of $72.6 million vs. the prior quarter, driven by a $48.8 million increase in the fair value of available-for-sale debt securities due to changes in market rates recognized as part of accumulated other comprehensive loss and the earnings generated during the quarter Partially offset by $28.7 million in common stock dividends declared during the quarter and $50.0 million in common stock repurchases All regulatory ratios remain significantly above “well-capitalized” levels Evolution of ACL ($MM) and ACL on Loans to Total Loans (%) Capital Ratios (%) The allowance for credit losses (ACL) on loans and leases was $247.0 million, down $1.6 million vs. prior quarter; the ratio of the ACL on loans and finance leases to total loans held for investment decreased to 1.89% Reduction was mainly related to a $2.1 million decrease in the mortgage ACL based on updated historical loss experience and a $1.4 million decrease in the consumer ACL associated with better unemployment rate projections and lower portfolio balances Net charge-offs of $19.9 million, 0.62% of average loans, compared to $19.1 million or 0.60% in prior quarter, increase mostly driven by lower commercial loan recoveries and slightly higher consumer charge-offs Key Highlights Key Highlights $0.0 1.72% 2019 2.61% Day-1 CECL 1.98% 3Q24 1.93% 2Q25 1.89% 3Q25 $155.0 $248.0 $252.1 $253.2 $251.0 Off-BS Credit Exposure & Debt Securities Loans ACL on Loans/Loans 16.2 3Q24 4Q24 1Q25 2Q25 3Q25 Total Risk-Based Capital Tier-1 Capital Tier-1 Common Leverage Tangible Common

Third Quarter 2025 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.

Third Quarter 2025 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. 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.

Third Quarter 2025 Appendix - Use of Non-GAAP Financial Measures Special Items Certain non-GAAP financial measures, such as adjusted non-interest expenses, adjusted income tax expense, adjusted net income, adjusted earnings per share, adjusted return on average assets, adjusted return on average equity, and adjusted pre-tax, pre-provision income, exclude the effect of items that management believes are not reflective of core operating performance (the “Special Items”). The financial results for the quarter ended September 30, 2025, included the following Special Items: Enactment of Act 65-2025 - On July 17, 2025, the Government of Puerto Rico enacted Act 65-2025 which, among other things, allows domestic limited liability companies owned by legal entities to elect to be treated as disregarded entities for tax purposes. As a result of this change, during the third quarter of 2025, the Corporation reversed approximately $16.6 million in valuation allowance related to deferred tax assets primarily associated with NOL carryforwards at the holding company level. This reversal reflects the Corporation’s expectation of realizing these tax benefits under the new election established by the Act. As of September 30, 2025, the remaining valuation allowance related to deferred tax assets associated with NOL carryforwards at the holding company level was approximately $1.0 million. Employee Retention Credit (“ERC”) - During the third quarter of 2025, the Corporation recognized a $2.3 million ERC, net of $0.3 million in related commissions. This amount is reflected in the condensed consolidated statements of income as part of “employees’ compensation and benefits” expenses. This credit was established under the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act to support businesses that retained employees during the COVID-19 pandemic. The credit recorded during the third quarter of 2025 is tax exempt for Puerto Rico tax purposes.

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. Adjusted Tangible Common Equity Ratio Adjusted tangible common equity, which is total common equity less goodwill and other intangibles, after exclusion of net unrealized losses on available-for-sale debt securities recognized as part of accumulated other comprehensive loss and Special Items, divided by adjusted tangible assets, which are total assets less goodwill and other intangible assets, after exclusion of the net unrealized losses on available-for- sale debt securities. Adjusted Tangible Book Value Per Share Adjusted tangible common equity, which is total common equity less goodwill and other intangibles, after exclusion of net unrealized losses on available-for-sale debt securities recognized as part of accumulated other comprehensive loss and Special Items, divided by common shares outstanding. Adjusted Return on Average Common Equity Ratio Adjusted 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 and Special Items.
