Insights

Corporate Filings Analyst

TL;DR: The 8-K links a joint press release and investor presentation dated October 6, 2025 but contains no standalone financial metrics.

The filing primarily references external documents — including Fifth Third's Form 10-K (Dec 31, 2024) and proxy filings (filed Mar 4, 2025) — rather than presenting new financial figures within the 8-K itself.

This means investors must review the linked press release and investor presentation to assess material financial or strategic details; the 8-K functions as a notification and access point rather than a self-contained disclosure.

Legal/Compliance Analyst

TL;DR: The filing includes standard forward-looking statements and a disclaimer of update obligations.

The 8-K reiterates customary cautionary language that forward-looking statements are subject to risks and refers readers to prior SEC filings for additional risk factors.

From a compliance standpoint, the document identifies the sources of relevant disclosures and the authorized signatory (Bryan D. Preston), supporting traceability and regulatory formality.

FORWARD-LOOKING STATEMENTS

This Current Report on Form 8-K contains statements that constitute “forward-looking statements” within the meaning of, and subject to the protections of, Section 27A of the Securities Act, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as “achieve,” “anticipate,” “assume,” “believe,” “could,” “deliver,” “drive,” “enhance,” “estimate,” “expect,” “focus,” “future,” “goal,” “grow,” “guidance,” “intend,” “may,” “might,” “plan,” “position,” “potential,” “predict,” “project,” “opportunity,” “outlook,” “should,” “strategy,” “target,” “trajectory,” “trend,” “will,” “would,” and other similar words and expressions or the negative of such terms or other comparable terminology. Forward-looking statements include, but are not limited to, statements about our business strategy, goals and objectives, projected financial and operating results, including outlook for future growth, and future common share dividends, common share repurchases and other uses of capital. These statements are not historical facts, but instead represent our beliefs regarding future events, many of which, by their nature, are inherently uncertain and outside of our control.

Comerica Incorporated’s (“Comerica”) and Fifth Third Bancorp’s (“Fifth Third”) actual results and financial condition may differ materially from those indicated in these forward-looking statements. Important factors that could cause Comerica’s and Fifth Third’s actual results, financial condition and predictions to differ materially from those indicated in such forward-looking statements include, in addition to those set forth in our and Fifth Third’s filings with the U.S. Securities and Exchange Commission (the “SEC”): (1) the risk that the cost savings and synergies from the merger of Comerica with Fifth Third (the “Transaction”) may not be fully realized or may take longer than anticipated to be realized; (2) the failure of the closing conditions in the merger agreement between Comerica and Fifth Third providing for the Transaction to be satisfied, or any unexpected delay in closing the Transaction or the occurrence of any event, change or other circumstances, including the impact and timing of any government

shutdown, that could delay the Transaction or could give rise to the termination of the merger agreement; (3) the outcome of any legal or regulatory proceedings or governmental inquiries or investigations that may be currently pending or later instituted against Comerica, Fifth Third or the combined company; (4) the possibility that the Transaction does not close when expected or at all because required regulatory, stockholder or other approvals and other conditions to closing are not received or satisfied on a timely basis or at all (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed Transaction); (5) the risk that the benefits from the Transaction may not be fully realized or may take longer to realize than expected, including as a result of changes in, or problems arising from, general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which Comerica and Fifth Third operate; (6) disruption to the parties’ businesses as a result of the announcement and pendency of the Transaction; (7) the costs associated with the anticipated length of time of the pendency of the Transaction, including the restrictions contained in the definitive merger agreement on the ability of Comerica or Fifth Third to operate its business outside the ordinary course during the pendency of the Transaction; (8) risks related to management and oversight of the expanded business and operations of the combined company following the closing of the proposed Transaction; (9) the risk that the integration of each party’s operations will be materially delayed or will be more costly or difficult than expected or that the parties are otherwise unable to successfully integrate each party’s businesses into the other’s businesses; (10) the possibility that the Transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; (11) reputational risk and potential adverse reactions of Comerica or Fifth Third customers, employees, vendors, contractors or other business partners, including those resulting from the announcement or completion of the Transaction; (12) the dilution caused by Fifth Third’s issuance of additional shares of its common stock in connection with the Transaction; (13) a material adverse change in the condition of Comerica or Fifth Third; (14) the extent to which Comerica’s or Fifth Third’s businesses perform consistent with management’s expectations; (15) Comerica’s and Fifth Third’s ability to take advantage of growth opportunities and implement targeted initiatives in the timeframe and on the terms currently expected; (16) the inability to sustain revenue and earnings growth; (17) the execution and efficacy of recent strategic investments; (18) the timing and impact of Comerica’s Direct Express transition; (19) the impact of macroeconomic factors, such as changes in general economic conditions and monetary and fiscal policy, particularly on interest rates; (20) changes in customer behavior; (21) unfavorable developments concerning credit quality; (22) declines in the businesses or industries of Comerica’s or Fifth Third’s customers; (23) the possibility that the combined company is subject to additional regulatory requirements as a result of the proposed Transaction of expansion of the combined company’s business operations following the proposed Transaction; (24) general competitive, political and market conditions and other factors that may affect future results of Comerica and Fifth Third including changes in asset quality and credit risk; (25) security risks, including cybersecurity and data privacy risks, and capital markets; (26) inflation; (27) the impact, extent and timing of technological changes; (28) capital management activities; (29) competitive product and pricing pressures; (30) the outcomes of legal and regulatory proceedings and related financial services industry matters; and (31) compliance with regulatory requirements.

undertake no obligation to publicly update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise, except to the extent required by law.
