Comerica Bank, a subsidiary of the Corporation, provides the Plan with certain accounting and administrative services for which no fees are charged. Certain of the Plan's assets are invested in funds managed by Fidelity Investments, an affiliate of the Plan's recordkeeper. These transactions qualify as party-in-interest transactions; however, they are exempt from the prohibited transaction rules under ERISA.

On December 31, 2024 and 2023, the Plan held approximately 1.1 million and 1.2 million shares of Comerica Incorporated common stock with fair values of $71 million and $70 million, respectively. During the years ended December 31, 2024 and 2023, the Plan recorded dividend income from Comerica Incorporated common stock of $3 million and $4 million, respectively.

#### 6. Tax Status
