At September 30, 2026, and December 31, 2025, no ACL was established for AFS or HTM securities. Substantially all of the unrealized losses on the securities portfolio were the result of changes in market interest rates compared to the date the securities were acquired rather than the credit quality of the issuers or underlying loans. The Company does not expect to incur any credit losses on investment securities.

In the third quarter of 2026, Truist executed a strategic balance sheet repositioning of a portion of its AFS securities portfolio by selling $8.6 billion of longer-duration, lower-yielding agency MBS and purchasing $7.2 billion of shorter-duration, higher-yielding agency MBS and U.S. Treasury securities.
