These forward-looking statements are predicated on the beliefs and assumptions of Comerica's management based on information known to Comerica's management as of the date of this presentation and do not purport to speak as of any other date.

Such statements reflect the view of Comerica's management as of the date of this presentation with respect to future events and are subject to risks and uncertainties. Should one or more of these risks materialize or should underlying beliefs or assumptions prove incorrect, Comerica's actual results could differ materially from those discussed. Factors that could cause or contribute to such differences include credit risks (changes in customer behavior; unfavorable developments concerning credit quality; and declines or other changes in the businesses or industries of Comerica's customers); market risks (changes in monetary and fiscal policies; fluctuations in interest rates and their impact on deposit pricing; and transitions away from LIBOR towards new interest rate benchmarks); liquidity risks (Comerica's ability to maintain adequate sources of funding and liquidity; reductions in Comerica's credit rating; and the interdependence of financial service companies); technology risks (cybersecurity risks and heightened legislative and regulatory focus on cybersecurity and data privacy); operational risks (operational, systems or infrastructure failures; reliance on other companies to provide certain key components of business infrastructure; the impact of legal and regulatory proceedings or determinations; losses due to fraud; and controls and procedures failures); compliance risks (changes in regulation or oversight, or changes in Comerica’s status with respect to existing regulations or oversight; the effects of stringent capital requirements; and the impacts of future legislative, administrative or judicial changes to tax regulations); strategic risks (damage to Comerica's reputation; Comerica's ability to utilize technology to efficiently and effectively develop, market and deliver new products and services; competitive product and pricing pressures among financial institutions within Comerica's markets; the implementation of Comerica's strategies and business initiatives; management's ability to maintain and expand customer relationships; management's ability to retain key officers and employees; and any future strategic acquisitions or divestitures); and other general risks (changes in general economic, political or industry conditions; negative effects from inflation; the effectiveness of methods of reducing risk exposures; the effects of catastrophic events, including pandemics; physical or transition risks related to climate change; changes in accounting standards; the critical nature of Comerica's accounting policies; and the volatility of Comerica’s stock price). Comerica cautions that the foregoing list of factors is not all-inclusive. For discussion of factors that may cause actual results to differ from expectations, please refer to our filings with the Securities and Exchange Commission. In particular, please refer to “Item 1A.

41©2023, Comerica Inc. All rights reserved. Direct Express An important program for CMA & the customers we serve 1Apple App Store as of 10/9/23 • Summary: Comerica is the exclusive issuer of the Direct Express debit card for 4.5 million federal benefit recipients. • Driving Financial Inclusion: Helping the U.S. Treasury provide recipients ready, safe access to their government benefits was the founding mission of the Direct Express Program. Not only does the innovative prepaid card program deliver benefits more cost effectively and securely, it is an on- ramp to financial inclusion for millions of unbanked Americans - giving recipients the tools they need to participate fully in the economy. • Renewal History: In 2008, 2014 and again in 2020, Comerica was selected by the U.S. Treasury as the Financial Agent for their Direct Express Debit MasterCard Program. Comerica’s contract with the U.S. Treasury expires early 2025. • Strong Customer Satisfaction: Comerica has achieved a 90% (or better) cardholder satisfaction rating • Prioritizing Security: Since 2013, the U.S. Treasury has required all federal benefit recipients (with a few grandfathered exceptions) to receive their monthly benefits electronically, either by direct deposit or through the Direct Express debit card. With 100% of cardholders using EMV chip and PIN, it can be considered one of the most secure prepaid cards in the industry. • Unique Skill-set: We have developed the unique infrastructure, compliance and operations to administer this important program. Program Overview Deposit Trends Investments • Balances: ~$3B in 3Q23 average deposit balances (large fluctuations throughout the quarter due to timing cause ending balances to vary) • Intra-month patterns: Comerica receives most of the deposit balances on the 1st and 3rd days of each month (subject to change based on weekends or holidays) • Peaks & troughs: In September 2023, highest balance of $5.4B on 1st business day, lowest balance of $2.7B • Enhanced Digital Experience: Developed a new Direct Express mobile application with a 4.7-star rating and over 101,000 reviews on the Apple App Store; over 1 million mobile app users1 • Meeting Cardholders Where They Are: Unique partnership with Walmart that allows cardholders to withdraw the full balance on their card (up to $1,000) at less than half the cost that Walmart charges other customers for the same service. Since 90 percent of Direct Express cardholders visit a Walmart at least once a year, this has proven to be a very popular service. 4.7 Stars1 ©2023, Comerica Inc. All rights reserved.

Uninsured Deposits Comerica believes that the presentation of uninsured deposits adjusted for the impact of affiliate deposits provides enhanced clarity of uninsured deposits at risk. Total uninsured deposits as calculated per regulatory guidance and reported on schedule RC-O of Comerica Bank’s Call Report include affiliate deposits, which by definition have a different risk profile than other uninsured deposits.
