INVESTMENT SECURITIES AND OTHER SECURITIES

Debt securities are classified as held-to-maturity when Huntington has the intent and ability to hold the

securities to their maturity. All other debt and equity securities are classified as either available-for-sale or other

securities. The following tables provide amortized cost, fair value, and gross unrealized gains and losses by

investment category.

At March 31, 2026, substantially all HTM debt securities are comprised of securities issued by government-

sponsored entities or are explicitly guaranteed by the U.S. government. In addition, there were no HTM debt

securities considered past due at March 31, 2026. Based on an evaluation of available information as of March 31,

2026, including security type, counterparty credit quality, past events, current conditions, and reasonable and

supportable forecasts that are relevant to collectability of cash flows, Huntington does not expect to incur credit

losses on any security held in its AFS and HTM debt securities portfolio. There was no allowance related to securities

as of March 31, 2026 or December 31, 2025.

The carrying value of investment securities pledged to secure public and trust deposits, trading account

liabilities, U.S. Treasury demand notes, and security repurchase agreements, and to support borrowing capacity,

totaled $36.5 billion at March 31, 2026 and $29.7 billion at December 31, 2025.
