Words such as “achieve, anticipate, aspire, assume, believe, can, commit, confident, continue, could, designed, enhances, estimate, expect, feel, forecast, forward, future, goal, grow, guidance, guide, initiative, intend, look forward, maintain, may, might, mission, model, objective, opportunity, outcome, on track, outlook, plan, position, potential, project, propose, remain, risk, seek, should, signs, strategy, strive, target, trajectory, trend, until, well-positioned, will, would” or similar expressions, as they relate to Comerica, or to economic, market or other environmental conditions or its management, are intended to identify forward-looking statements. 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. Forward-looking statements may include descriptions of plans and objectives of Comerica's management for future or past operations, products or services, and forecasts of Comerica's revenue, earnings or other measures of economic performance, including statements of profitability, business segments and subsidiaries as well as estimates of credit trends and global stability. Such statements reflect the view of Comerica's management as of this date 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 the Bloomberg Short-Term Bank Yield Index 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 and their soundness); 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, processes and management estimates; the volatility of Comerica’s stock price; and that an investment in Comerica’s equity securities is not insured or guaranteed by the FDIC). 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. Risk Factors” beginning on page 14 of Comerica's Annual Report on Form 10-K for the year ended December 31, 2023. Forward-looking statements speak only as of the date they are made. Comerica does not undertake to update forward-looking statements to reflect facts, circumstances, assumptions or events that occur after the date the forward-looking statements are made. For any forward-looking statements made in this presentation or in any documents, Comerica claims the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

Direct Express Program update provided at 2Q24 earnings: Preliminary notification of non-selection • Summary: Comerica Bank is the exclusive issuer of the Direct Express debit card for approximately 4.5 million federal benefit recipients as of June 30, 2024. • Driving Financial Inclusion: Helping the U.S. Department of the Treasury, Bureau of the Fiscal Service (U.S. Treasury) provide recipients ready, safe access to their government benefits was the founding mission of the Direct Express Program. The prepaid card program is intended to deliver benefits more cost effectively and securely and to be an on- ramp to financial inclusion for millions of unbanked Americans, providing recipients the tools they need to participate fully in the economy. • Renewal History: In 2008, 2014 and again in 2020, Comerica Bank was selected by the U.S. Treasury as the Financial Agent for their Direct Express Debit MasterCard Program. Comerica Bank’s contract with the U.S. Treasury expires in early 2025. • Strong Customer Satisfaction: Since inception of the program, 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. Program Overview Financial Metrics Program Status • Balances: ~$3.3B in 2Q24 average deposit balances (large fluctuations throughout the quarter due to timing cause ending balances to vary). • Intra-month Patterns: Comerica Bank 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 June 2024, highest balance was $4.8B & lowest balance was $2.8B. • Income Statement: • $137MM FY23 & $29MM 2Q24 noninterest income (card fees) • $138MM FY23 & $29MM 2Q24 direct expenses primarily in outside processing fees, but also includes professional fees, operational losses, staff expenses & other fees • Re-Bid: We received a preliminary notification that Comerica Bank has not been selected to continue serving as the Financial Agent to support the program following contract expiration. • Transition Plan: If the preliminary non-selection of Comerica Bank remains the final disposition, we expect the formal transition plan for managing accounts & deposits to be agreed upon once contract negotiations are finalized with the new provider. We do not currently expect this transition to impact 2024 deposits, noninterest income or noninterest expenses. • Next Steps: We intend to continue to support our customers through the transition & prioritize efforts to drive deposits. 4.8 Stars1 1Apple App Store as of 7/11/24

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.
