FITB — Q3 2026 Financial Report Analysis

Comerica is now fully inside Fifth Third, and the combined bank earned more per share than last quarter

Fifth Third Bancorp earned $828 million for common shareholders in the third quarter of 2026, or $0.90 per diluted share, up from $0.83 in the second quarter and almost level with $0.91 a year ago. The year-ago comparison is distorted by the Comerica acquisition, which closed on February 1, 2026: profit is 36% higher than a year ago, but the share count is also about 37% higher because the deal was paid for in stock. The more useful comparison is with last quarter. Net interest income rose 3%, underlying costs fell 2%, and the bank finished converting Comerica's systems and customers. One-off charges, mostly merger costs, still took $0.23 off EPS. Fifth Third's adjusted EPS, which excludes them, was $1.13.

This analysis is based on the earnings release (8-K Exhibit 99.1, filed October 19, 2026) and the investor presentation filed with it. The full 10-Q has not been filed yet, so the cash flow statement and detailed management discussion are not available.

The numbers

*Year-ago adjusted EPS is our calculation from the release's reconciliation: $608 million of net income available to common plus $16 million of after-tax adjustments, divided by 670.9 million diluted shares.

A few definitions. Net interest income is what the bank earns on loans and securities minus what it pays depositors and lenders. Net interest margin (NIM) is that spread as a percentage of the bank's interest-earning assets. Fifth Third reports both on a "fully taxable-equivalent" (FTE) basis, which adds back about $5 million a quarter so tax-exempt loans can be compared with taxable ones. The NIM and efficiency ratio above are the company's FTE figures. The efficiency ratio is expenses as a share of revenue, so lower is better.

Nearly every year-over-year change in the table reflects the addition of Comerica, not organic growth. The release says so directly: net interest income rose 49% "primarily reflecting the addition of Comerica." That is why the rest of this report compares mostly with Q2, the first full quarter the two banks were combined.

Quarter on quarter: what actually moved

Lending income grew while the margin edged down. Net interest income (FTE) rose $56 million to $2,276 million. The bank attributes this to "higher market rates, continued fixed-rate asset repricing, active investment portfolio management, and loan growth." Repricing means older, low-rate loans and bonds rolling over into higher-rate ones. Two things worked against it: higher deposit costs, and Comerica customers' money moving out of off-balance-sheet investment sweep accounts into interest-bearing deposits that Fifth Third has to pay interest on. The yield on assets rose 4 basis points (a basis point is 0.01 percentage point) to 5.15%, but the rate paid on interest-bearing funding rose 6 bps to 2.50%. As a result, NIM slipped 2 bps to 3.34%. Net interest income still grew because the balance sheet was larger: average interest-earning assets rose 2% to $270 billion.

Loans grew slowly. Average portfolio loans rose 1% to $179.2 billion. That came from about $1.5 billion of commercial loan growth, while consumer loans were "broadly stable." Commercial originations were led by construction and C&I (commercial and industrial) loans, "partly offset by elevated payoffs." Solar installation loans continue to run off as planned, down 3% to $4.2 billion on average.

Deposits were the strongest line, but part of the growth came from the sweep migration. Average core deposits rose 3% to $235.6 billion. Period-end deposits rose 2% to $239.5 billion. The release cites three reasons: "operational deposit growth, the Southwest retail deposit campaign," and the sweep migration. It does not say how much each contributed. The extra deposits let Fifth Third cut average wholesale funding (borrowed money that costs more than deposits) by 10% to $23.3 billion, including $1.3 billion less long-term debt and $1.1 billion less in Federal Home Loan Bank advances. The loan-to-core-deposit ratio improved to 76% from 77%.

Fee income was flat once one-offs are removed. Reported fee income fell 5% to $1,008 million. Excluding interchange-litigation charges, merger charges and securities gains or losses, it rose 1% to $1,052 million. Mortgage banking (up 21% to $47 million), commercial banking and wealth management (up 1% to $259 million) grew. Capital markets fees fell 5% to $147 million because "late-quarter market volatility slowed M&A advisory and loan syndication activity."

Expenses fell. Reported noninterest expense fell 3% to $2,049 million, "driven primarily by lower compensation and benefits expense." That line fell $147 million to $982 million. Excluding merger charges, impairments, litigation and the mark-to-market on deferred-compensation plans, expenses fell 2% to $1,816 million. Technology and communications costs rose 20% to $300 million in the conversion quarter.

What the headline numbers hide

• Large one-off charges again, so GAAP and adjusted results are far apart. After tax, the items Fifth Third excludes totaled $211 million, or $0.23 per share. Merger-related charges were $171 million ($215 million pre-tax in expenses plus $10 million less fee income). Interchange-litigation matters were $26 million and technology asset impairments $14 million. Merger charges in expenses have reached about $1.04 billion so far this year. These costs should drop sharply now that the conversion is complete, but they are real cash costs of the deal, not accounting noise.
• The bond portfolio cost shareholders equity this quarter. Accumulated other comprehensive loss, which mainly tracks unrealized losses on bonds and hedges as rates change, widened to $4.92 billion from $3.29 billion. As a result, book value per share fell to $34.31 from $35.63 and tangible book value per share to $22.01 from $23.22. This is the main thing the higher EPS figure doesn't show. Regulatory CET1 capital excludes these losses, so it still rose. The TCE ratio that includes them fell to 6.88% from 7.29%.
• No help from buybacks or a share-count drop. Fifth Third "did not repurchase common shares during the quarter or year-to-date." Diluted shares were essentially flat from Q2 (917.1 million versus 916.0 million), so the 8% sequential EPS gain came from higher earnings. The effective tax rate fell to 21.8% from 22.7%, worth roughly $10 million, a small tailwind.
• The year-ago credit comparison is distorted. The net charge-off ratio improved from 1.09% to 0.31%. Net charge-offs are loans written off as uncollectable, net of recoveries. Most of the improvement is because Q3 2025 included a $178 million charge-off on a single asset-backed finance credit. Excluding it, the year-ago ratio was 0.52%. Compared with Q2, credit was stable: commercial charge-offs were 0.22% and consumer 0.52%.
• Nonperforming assets rose, but mostly from closed branches. Nonperforming assets rose to $1,160 million from $1,075 million. Of that increase, $57 million is foreclosed or surplus property (OREO), which jumped to $81 million and includes $74 million of "branch-related real estate no longer intended to be used for banking purposes," mostly from Comerica. Nonaccrual loans rose more modestly, to $1,070 million from $1,041 million. The provision ($122 million) was below net charge-offs ($139 million), so the loan-loss reserve fell slightly to 1.74% of loans from 1.76%. The release attributes that to "improvement in the commercial risk profile."
• Cash flow can't be checked yet. Earnings releases do not include a cash flow statement. That comparison waits for the 10-Q.

Takeaway: The deal is now showing up in per-share profit. Adjusted pre-provision earnings, which are revenue minus expenses before setting aside money for bad loans, rose 8% in one quarter to $1.51 billion. Adjusted ROTCE (return on tangible common equity) reached 20.6%, and Q4 guidance points higher. The weak spot is the balance sheet: rising unrealized bond losses cut tangible book value per share by 5% in the same quarter. With CET1 at 10.02% and no buybacks this year, capital is what limits how fast the earnings gains reach shareholders.

Did last time's read hold up?

Our Q2 report pointed to deposit growth as the number to watch, after legacy core deposits shrank in the first half. Core deposits did grow 3% on average in Q3, though some of that came from Comerica's sweep balances moving onto the balance sheet. The company met or beat every line of its Q3 guidance:

• Net interest income rose 2.5%, at the top of the 2–2.5% range.
• Noninterest expense, measured on the guidance basis, fell 2.4%, better than the guided 1–2% decline.
• Fee income rose 1.2%, at the low end of the 1–3% range.
• The net charge-off ratio was 0.31%, inside the 30–35 bps range.

We also flagged whether the margin would hold as purchase-accounting accretion fades. It slipped 2 bps, which is not a meaningful break. CET1 is being rebuilt, up 9 bps to 10.02%, and buybacks have not resumed.

Outlook

Management's Q4 2026 guidance (investor presentation, October 19), measured against Q3 baselines:

• Average loans and leases (including held for sale): up 1–2%
• Net interest income (FTE): up 2.5–3.5% from $2.28 billion. This assumes the fed funds rate is 4.25% at December 31 and includes purchase-accounting accretion.
• Fee income excluding securities gains and losses: up 2–4% from $1.05 billion
• Noninterest expense: down 2–3% from $1.82 billion. This includes about $60 million of amortization of the value assigned to Comerica's deposits and excludes acquisition charges.
• Net charge-off ratio: 30–35 bps. Effective tax rate: 22.5%.

If those ranges hold, adjusted pre-provision earnings would be roughly $1.6–1.7 billion in Q4, up from $1.51 billion, by our arithmetic from the midpoints. That would be the first quarter with the full cost savings and no conversion spending. The risks are in funding. CEO Tim Spence said "competition for deposits is heating up," and the sweep migration is already raising deposit costs, so the NIM could keep slipping even as net interest income grows. In our view, the Q4 test has two parts: whether loan growth reaches the guided 1–2% after 0.7% this quarter, and whether capital rises fast enough to restart buybacks, given that unrealized bond losses grew this quarter.
