As of March 31, 2026 and December 31, 2025, the amortized cost of investment securities excludes accrued interest receivable, included in the accrued interest receivable line in OFG’s consolidated statements of financial condition. Refer to Note 9 – Accrued Interest Receivable and Other Assets

Securities not due on a single contractual maturity date, such as collateralized mortgage obligations, are classified in the period of final contractual maturity. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

Investment securities as of March 31, 2026, include $1.310 billion pledged to secure government deposits, regulatory collateral, and borrowings, of which $1.200 billion serve as collateral for public funds. Investment securities as of December 31, 2025, include $1.724 billion pledged to secure government deposits, regulatory collateral, and borrowings, of which $1.614 billion serve as collateral for public funds. For regulatory collateral, the secured parties are not permitted to sell or repledge the collateral.

The Bank’s IBEs, OIB and Oriental Overseas, each held short-term US Treasury securities in the amount of $1.0 million and $775 thousand at March 31, 2026 and December 31, 2025, respectively, as the legal reserve required for international banking entities under Puerto Rico law. These instruments cannot be withdrawn or transferred without the prior written approval of the Office Commissioner of Financial Institutions.

The unrealized losses on OFG’s investment in federal agency mortgage-backed securities were caused by market volatility related to market uncertainty tied to interest rate fluctuations. OFG purchased those investments at a discount relative to their face amount, and the contractual cash flows of those investments are guaranteed by an agency of the U.S. government or by a government-sponsored enterprise. Accordingly, it is expected that the securities would not be settled at a price that is less than the amortized cost basis of OFG’s investments. OFG does not intend to sell the investments, and it is not more likely than not that OFG will be required to sell the investments before recovery of their amortized cost basis.
