American Express Q3 2026 Earnings: Record $20.1B Revenue and the $982M GBTG Gain

On October 23, 2026, American Express reported record third-quarter revenue of $20.1 billion, up 9%, and EPS of $5.42, up 31%. But $1.11 of that $5.42 came from selling the company's stake in Global Business Travel Group — a one-time gain that did more for EPS growth than the entire card business. Strip it out, and the quarter is still good: adjusted EPS up 13% on genuine spend momentum and excellent credit. This post separates the two stories, line by line, in a ledger you can audit.

The Headline Numbers​

Every figure below comes from the Form 10-Q and the earnings release, with segment detail from the financial supplement. The quarter ended September 30, 2026:

Read the rows in pairs and the quarter decomposes cleanly. Revenue grew 9% on real drivers — higher Card Member spending, net interest income supported by growth in card balances, and strong card fee growth, per the release. Provisions fell 24% because the company released reserves this quarter against a build last year. Then the GBTG sale dropped $982 million of pre-tax gain into operating expenses, and a discrete tax benefit pushed the effective rate down to 18.1% from 24.1%. Revenue up 9%, net income up 28%, EPS up 31%: each step down the income statement adds leverage, and only the first step is pure operations.

Revenue Deep Dive: Four Engines, One Flywheel​

Start with the revenue lines, because they show what American Express actually sells — and it is not credit:

Discount revenue — the toll on every swipe — is still half the top line and grew 8% on billed business of $454 billion. Net interest income grew 10% as interest expense fell 10% (funding costs easing) while the card book kept growing. But the standout is card fees at +16% — the fastest line in the model, growing at twice the pace of spending itself. Squeri's comment that "our business momentum continues, with strength in billings, new acquisitions and Card Member retention" is the demand signal behind it, with the U.S. Platinum Card refresh driving engagement (and, on the cost side, the services bill discussed below). Card fees are the purest pricing-power line in the model — members paying more per year for the right to spend — and it is growing at twice the pace of spending itself.

Service fees look flat at +0.4%, but the comparison is dirty in a way the 10-Q discloses: the year-ago quarter included a gain on an equity transaction by GBTG, then an equity-method investee, from its acquisition of CWT. The amount is not quantified, so the underlying growth in network partnership revenue, foreign-exchange fees on cross-currency spending, and merchant service fees is hidden inside a flat print. Note the irony for the One Big Question below: GBTG flattered both this quarter (the sale gain) and the comparison quarter (the CWT gain).

The segment cut shows where the growth lives:

U.S. Consumer is the engine: 49% of revenue, 11% growth, pretax up 24% as provisions in the segment fell 33%. Commercial Services is the puzzle — revenue up 6% but pretax down 6%, as rewards and engagement costs (+14%) plus a 29% jump in marketing outran the top line. International grew revenue 10% on billed business up 11%, yet pretax slipped 2% on the same engagement-cost pressure. And GMNS, the network toll booth, printed a 52% pretax margin ($1,082 million on $2,082 million) on network volumes of $518 billion, up 8%. When half your segments grow pretax double-digits and the other half shrink it on rising engagement costs, the margin story writes itself.

The Margin Story: Reported Expansion, Underlying Compression​

The reported margin expanded 180 basis points. The adjusted margin — pretax income less the $982 million gain plus the $336 million restructuring charge, over revenue — compressed 140 basis points to 19.4%. That compression has a mechanical cause: variable customer engagement costs (rewards, business development, card services) rose 16% to $8,891 million against 9% revenue growth, "due to increased Card Member spending and the U.S. Platinum Card refresh," per the release. Card Member services alone jumped 36% to $2,006 million. This is the Membership Model's treadmill: the spending growth that drives discount revenue simultaneously triggers the rewards and perks that cost against it, and the Platinum refresh steepened the trade this quarter.

Two cushions softened the landing. Provisions fell $302 million year over year — a reserve release versus a prior-year build — though the release notes net write-offs rose in dollars even as the write-off rate ticked down to 1.8% from 1.9% (the denominator grew faster than the losses). And the tax rate dropped six full points on discrete benefits from resolving prior-period items, contributing roughly $270 million of the $810 million net-income increase. Neither cushion is recurring operating leverage; both are timing. The bull case is that engagement spending buys retention Squeri keeps citing; the bear case is that 16% cost growth against 9% revenue growth is a mix shift, not an investment blip. Watch the services line — it has now outgrown revenue in every comparison this ledger covers, from +21% in FY2024 to +36% this quarter.

The One Big Question: What Does the Guide Imply for Q4?​

The release raises full-year EPS guidance to $18.30–$18.60 on a GAAP basis ($17.60–$17.90 adjusted) and says the company is "on track to deliver another year of 10 percent revenue growth." Sounds unambiguous — until you do the subtraction. Start with the bridge the release itself provides:

Now extend it to the guide. Nine-month GAAP EPS stands at $14.22, so the $18.30–$18.60 range implies Q4 GAAP EPS of $4.08–$4.38. Nine-month adjusted EPS is $13.49, so the $17.60–$17.90 range implies Q4 adjusted EPS of $4.11–$4.41 — below Q3's $4.68 on either basis. Some of that is mechanical: Q3 held the $1.11 gain, and Q4 carries seasonal marketing weight. But it means the "raise" prices in a sequential step-down, and the full-year beat now depends on the fourth quarter landing a number lower than the third — a bar constructed to be cleared, not a forecast of acceleration.

The credit side deserves the same bridge treatment. Provisions of $985 million look 24% better than last year, but the release says the decrease "reflected a reserve release during the quarter compared to a reserve build in the prior year, partially offset by higher net write-offs." The allowance on Card balances fell to $5,634 million from $6,089 million at year-end while the balances themselves grew to $215,440 million — coverage thinning from 2.85% to 2.55% as the book expands. That is exactly what "excellent credit performance" licenses management to do, and the 1.8% write-off rate supports it. It also means next quarter's provision compares against a release, not a build. The question for Q4 is not whether credit is good — it is — but whether the P&L gets another reserve tailwind after this one.

Tracking a $310 Billion Balance Sheet in Plain Text​

A card network is the ideal subject for double-entry modeling: every dollar of Card Member spending becomes discount revenue, a receivable, a reward liability, and eventually cash — and Beancount forces each of those transformations to reconcile.

Income posts negative (credit), expenses positive (debit), and the transaction sums to zero. The balance-sheet number that tells the Amex story is Card balances at $215,440 million — up from $207,774 million at year-end, the asset the entire revenue model rents out. Its mirror is Other assets, which quietly holds a $1.5 billion receivable for the GBTG sale proceeds that arrived after quarter-end: the gain is in this quarter's earnings, but the cash lands in Q4's. Customer deposits of $155,019 million fund most of the book, which is how a 10% drop in interest expense handed net interest income its double-digit growth.

The Multi-Year Arc: The Toll Booth Keeps Widening​

This ledger opens at FY2024 with two audited annuals and the latest quarter — the full span:

Three things compound here. First, the fee franchise: net card fees grew 18% in FY2025 and are running 17% ahead year-to-date — the fastest line in the model two years running, and the one most insulated from credit cycles. Second, the balance sheet: the card book added $22 billion since the end of FY2024 while customer deposits added $15.6 billion, keeping the funding mix deposit-led as net interest income scaled. Third, the share count: $17.6 billion of repurchases across these six quarters retired 31 million shares, so 7% net-income growth in FY2025 became 10% EPS growth. Nine-month EPS of $14.22 already exceeds all of FY2024's $14.01 — with the seasonally strongest spending quarter still to come.

The Verdict: Bull vs. Bear​

Bull Case

• Billed business of $454 billion (+8%) with "strength in billings, new acquisitions and Card Member retention" (Squeri) — the spend flywheel is intact and management's demand language matches the ledger.
• Card fees +16% show pricing power: fee income growing at twice the pace of spending while U.S. Consumer cards-in-force grew 4% and International 6%.
• Credit is genuinely excellent — 1.8% write-off rate, down from 1.9% — which licenses both the reserve release and continued book growth at a 2.55% coverage ratio.
• Net interest income +10% with interest expense −10%: the deposit-funded balance sheet turns every rate cut into margin, no action required.
• The raised adjusted guide ($17.60–$17.90, +14–16% on FY2025's $15.38) is beatable on run-rate alone: Q4 merely matching Q3's $4.68 would land FY2026 at $18.17.

Bear Case

• $1.11 of $5.42 EPS is a non-recurring sale gain; the "31% EPS growth" headline is 13% on an adjusted basis, and Q3 2025's comparison was itself flattered by an unquantified GBTG-related gain.
• Engagement costs (+16%) structurally outrun revenue (+9%): rewards, services, and refresh spending grow with every swipe, compressing the adjusted pretax margin 140bps this quarter.
• Provisions got a one-way tailwind — a release versus a prior-year build — while net write-offs rose in dollars; coverage thinned to 2.55% as the book grew.
• A $400 million legal-reserve increase for the OCC penalty plus the $185 million IRS transfer-pricing dispute (with $50 million in asserted penalties) show regulatory costs compounding alongside the business.
• The guide's implied Q4 ($4.11–$4.41 adjusted) sits below Q3's $4.68 — the raise is a lowered bar for the seasonally strongest quarter, which reads as caution, not confidence.

Our Take: Buy the flywheel, discount the print. The 9% revenue growth, 16% card-fee growth, and 1.8% write-off rate are the real American Express — a premium-spend franchise with underwriting most lenders would pay up for. But nearly a fifth of this quarter's EPS is a stock sale, the margin expanded only on paper, and the guide quietly concedes the fourth quarter steps down. Value this company on the $4.68, not the $5.42 — and on that basis, it still earns its multiple.
