Additional paid-in capital represents contributed capital in excess of par value of common stock, net of the costs of issuance. At both March 31, 2026 and December 31, 2025, accumulated common stock issuance costs charged against additional paid-in capital amounted to $13.6 million.

The Banking Act requires that a minimum of 10% of the Bank’s net income for the year be transferred to a reserve fund until such fund (legal surplus) equals the total paid-in capital on common and preferred stock. At March 31, 2026 and December 31, 2025, the Bank’s legal surplus amounted to $193.8 million and $188.5 million, respectively. During the quarters ended March 31, 2026 and 2025, OFG transferred $5.3 million and $4.4 million, respectively, to the legal surplus account. The amount transferred to the legal surplus account is not available for the payment of dividends to shareholders.

In January 2026, OFG's Board of Directors (the “Board”) approved a new $200.0 million stock repurchase program in addition to the $100.0 million stock repurchase program approved in April 2025 (the “Existing Repurchase Programs”). The shares of

common stock repurchased are held by OFG as treasury shares. OFG records treasury stock purchases under the cost method whereby the entire cost of the acquired stock is recorded as treasury stock.

During the quarters ended March 31, 2026 and 2025, OFG repurchased 1,097,953 and 582,399 shares, respectively, for a total of $44.5 million and $23.4 million, at an average price of $40.51 and $40.17 per share, under the approved stock repurchase programs for such periods.

At March 31, 2026, the estimated remaining number of shares that may be purchased under the Existing Repurchase Programs is 4,785,159 and was calculated by dividing the remaining balance of $193.6 million by $40.46 (closing price of OFG’s common stock at March 31, 2026).

OFG did not repurchase any shares of its common stock during the quarters ended March 31, 2026 and 2025, other than through its publicly announced stock repurchase programs.

The activity in connection with common shares held in treasury by OFG for the quarters ended March 31, 2026 and 2025, is set forth below:
