Summary
Summary of the 8-K filed October 6, 2025. Cited figures are marked; the original filing is the authoritative source.
On October 6, 2025, Fifth Third Bancorp (FITB) and Comerica Incorporated (CMA) announced a definitive merger agreement under which Comerica will merge into Fifth Third Financial Corporation, a wholly-owned subsidiary of Fifth Third.
The all-stock transaction is valued at approximately $10.9 billiona. Comerica stockholders will receive 1.8663 Fifth Third shares per Comerica share, implying $82.88 per share based on Fifth Third's October 3, 2025 closing price and a 20% premium to Comerica's 10-day VWAP. Pro forma ownership will be roughly 73% Fifth Third and 27% Comerica, and the combined company would be the 9th largest U.S. bank with about $288 billion in assets.
Management projects the deal to be immediately accretive, with 2027E EPS accretion of roughly 9% ($4.89b pro forma versus $4.50 consensus), a 19%+ return on tangible common equity, and an efficiency ratio in the low-to-mid 50s. The key earnings driver is $850 million of pre-tax expense synergies, equal to about 35% of Comerica's projected noninterest expense base. Costs to achieve are estimated at $1.3 billion pre-tax (1.5x synergies), recognized at close.
The company cites a 22% IRR, a price/tangible book value of 1.73x, and a price/2026E earnings multiple of 15.4x (7.9x including synergies). Credit and rate purchase accounting marks total roughly $806 millionc gross credit mark and a $1.7 billion after-tax AFS securities rate mark. The transaction is expected to close at the end of Q1 2026 (presentation assumes March 31, 2026), subject to shareholder approvals at both companies and customary regulatory approvals.
Strategically, the deal expands Fifth Third's presence in high-growth Southeast, Texas, and California markets, adds a larger middle-market commercial franchise, and builds two $1Bd+ fee businesses (Commercial Payments and Wealth and Asset Management). Investors should weigh the expected accretion and synergy case against integration execution risk, regulatory timing, dilution to existing Fifth Third shareholders (about 27% of the combined company goes to Comerica holders), and the typical risks associated with large bank combinations. Note that the filing itself is a Regulation FD disclosure and the investor materials contain forward-looking projections not guaranteed to be achieved.

03—Questions
Frequently Asked Questions
What will Comerica shareholders receive in the transaction?
Comerica stockholders will receive 1.8663 shares of Fifth Third common stock for each Comerica share. Based on Fifth Third's October 3, 2025 closing price, this equals $82.88 per Comerica share, a 20% premium to Comerica's 10-day volume-weighted average price. The consideration is 100% stock.
Is the deal expected to be accretive to Fifth Third shareholders?
Management expects the transaction to be immediately accretive. The investor presentation projects 2027E EPS of $4.89 pro forma versus $4.50 consensus for Fifth Third standalone, or about 9% accretion. Tangible book value per share is projected to be roughly neutral at close, with about 4.7% accretion excluding the one-time charge under certain timing assumptions. These are management projections and depend on achieving synergies and integration.
What are the main risks to completing the deal?
Key risks include failure to obtain regulatory or shareholder approvals (or approvals with adverse conditions), delays from government actions such as a shutdown, difficulty realizing the $850 million cost synergies, integration challenges, customer and employee attrition, credit quality deterioration in the combined loan book, and possible higher-than-expected costs. The filing also flags the dilution from issuing new Fifth Third shares.
What does the deal mean for Fifth Third's geographic footprint and business mix?
The combination adds Comerica's middle-market franchise and presence in Texas, California, Arizona, and Florida, which management says positions the combined company in 17 of the 20 fastest-growing large U.S. metros. By 2030, over half of Fifth Third's branches are expected to be in the Southeast, Texas, Arizona, and California. The company also highlights two $1B+ recurring fee businesses: Commercial Payments and Wealth and Asset Management.
When is the transaction expected to close and what approvals are needed?
The transaction is expected to close at the end of the first quarter of 2026. Closing requires approval from shareholders of both Fifth Third and Comerica, customary regulatory approvals, and satisfaction of other closing conditions. Fifth Third plans to file a Form S-4 registration statement that includes a joint proxy statement/prospectus.
