AXP — Q3 2026 Financial Report Analysis

A 31% EPS jump that is mostly a one-off sale, a lower tax bill and buybacks

American Express reported third-quarter 2026 revenue (total revenues net of interest expense) of $20.06 billion, up 9% from $18.43 billion, and diluted earnings per share of $5.42, up 31% from $4.14. Cardholder spending (billed business) rose 8% to $454.0 billion, and the company raised its full-year EPS guidance to $18.30–$18.60.

Almost none of that 31% came from the card business earning more. The quarter includes a $982 million pre-tax gain from selling Amex's stake in Global Business Travel Group (GBTG), partly used to pay for a $336 million restructuring charge. Amex's own adjusted figures strip both out: adjusted EPS was $4.68, up 13%. Even that 13% leans on a tax rate that fell to 18.1% from 24.1% and on 3% fewer shares outstanding. On our arithmetic from the release, adjusted pretax income rose just 1.6%, and the operating business before credit costs earned about 5% less than a year ago.

This report is written from the earnings release and statistical tables (Exhibits 99.1 and 99.2 to the 8-K filed 2026-10-23). The full 10-Q, with the cash flow statement and management's line-by-line commentary, has not been filed yet.

Headline metrics

A few terms. Net interest income is the interest Amex earns on card balances minus what it pays on deposits and debt. Amex does not publish a bank-style net interest margin; the closest figure it gives is the net interest yield (net interest income divided by average card balances and other loans, annualized), which is what the figures above and the site's NIM column use. The net write-off rate is the share of balances Amex gave up on as uncollectible, annualized; we use the principal-only version Amex calls "consistent with industry convention". CET1 is the core capital regulators require a bank to hold against its risk-weighted assets. Amex states no efficiency ratio or return on tangible common equity, so those are left out.

What the headline numbers hide

The one-off sale. "Other, net" expense swung to a $218 million credit from a $406 million charge a year ago, because the $982 million GBTG gain is booked inside that expense line. Amex used part of it to fund restructuring "related to efficiency initiatives", and the release says operating expenses also carried "an increase in legal reserves for previously-disclosed matters". The release does not say how large the legal-reserve increase was. Net of tax, the gain added $1.11 per share and the restructuring took off $0.37.

Strip both out and pretax income barely grew. Pretax income less the gain plus the restructuring charge is $3,885 million, against $3,825 million a year ago: +1.6%. Pre-provision profit (revenue minus expenses, before credit-loss charges), on the same adjusted basis, was about $4.87 billion, down from $5.11 billion, roughly −5%. Three things outran 9% revenue growth:

• Customer-engagement costs (rewards, business development and Card Member services together) rose 16% to $8.89 billion, taking 44.3% of revenue against 41.8% a year ago.
• Marketing rose 11% to $1.77 billion.
• Operating expenses (salaries, professional services, technology and other), once the gain and restructuring are taken out, rose about 13%, with salaries and benefits alone up 15% to $2.57 billion. The undisclosed legal-reserve increase sits in this bucket.

The credit line covered the gap. Provisions fell $302 million, more than the entire $60 million rise in adjusted pretax income. Most of it was a reserve release, not lower write-offs: the reserve against card balances fell by $232 million in the quarter (from $5,866 million to $5,634 million) while a year ago it grew by $108 million. Actual net write-offs on card balances rose 2% to $1,130 million. With delinquencies at 1.2% the release is consistent with the data, but it is a drawdown of a cushion, not a recurring source of profit.

Where adjusted EPS growth came from. Holding the tax rate at last year's 24.1% and the share count at 693 million, adjusted EPS would have been about $4.16. The buyback (674 million average diluted shares against 693 million) adds about $0.12, and the lower tax rate, which Amex attributes to "discrete tax benefits... related to the resolution of certain prior-period tax items", adds about $0.40. The adjusted tax rate works out to roughly 17.3%. Neither the tax benefit nor the reserve release is a steady part of earnings.

Not checkable yet: cash conversion (operating cash flow against net income) and receivables quality beyond the delinquency figures need the 10-Q's cash flow statement, which isn't out.

Takeaway: Amex's customers are spending and paying more, and paying back reliably, but in Q3 that did not turn into higher operating profit. Strip out the one-off sale and restructuring and pretax income grew 1.6%; take away a $300 million drop in credit-loss charges, mostly a reserve release, and it fell. Adjusted EPS grew 13% because of a lower tax rate and buybacks, not because the business earned more.

The Platinum cost curve is flattening

Last quarter's central issue was that the refreshed U.S. Platinum card's benefits were costing more than its higher fees brought in. That gap is narrowing:

In Q2, services expense grew $266 million more than card fees; in Q3 the gap was $111 million. The quarterly figures show why: services expense jumped from $1,477 million in Q3 2025 to $1,951 million in Q4 2025 and has been flat at about $1.95–2.0 billion since. Once Q4 2026 laps that step-up, the year-on-year growth rate should fall sharply, while fees keep compounding: the average fee per card rose 14% while proprietary basic cards grew 2%. Fee growth here is mostly price, not more customers; new proprietary cards acquired were 3.1 million against 3.2 million a year ago.

Interest income: cheaper funding, not just bigger balances

Net interest income grew 10% while interest income grew only 4%. The difference is the cost side: interest expense fell 10% to $1,918 million, including 9% less paid on deposits ($1,242 million) even as deposits grew 3%. Card balances grew 7% to $221.1 billion. That pushed the net interest yield to 8.5% from 8.2%. Lower rates also cut what Amex earns on its own cash (interest on deposits with banks fell 33% to $426 million), so the benefit is net of that.

Segments

U.S. Consumer again looks strongest, and again the provision did much of the work: of the $443 million pretax increase, $240 million came from lower credit charges (provisions fell 33% to $494 million). Its principal-only write-off rate fell to 1.6% from 1.8%.

Commercial Services profit fell 6% as expenses rose 14% (marketing +29%) against 3% spending growth. Its card count dropped 11% to 13.7 million because Amex sold small-business cobrand portfolios it had classified as held for sale, the "moderation in spend growth" management warned of in Q2.

International grew spending 11% (also 11% excluding currency moves) but earned slightly less, with expenses up 14%. Two quarters running, its volume growth has not reached the bottom line.

Spending in goods and services slowed to +7% from +9% in Q2; travel and entertainment held at +10% and is now 29% of billed business.

Capital and returns

CET1 rose to 10.9% from 10.4% at the end of Q2, helped by the gain and a slower buyback: Amex repurchased about 5 million shares in Q3 against 7 million in Q2. Return on average equity of 42.4% is inflated by the gain; the year-to-date figure is 38.0%. Book value per share rose 14% to $51.02. Amex also refinanced $1.6 billion of preferred shares at 6.450% (replacing a 3.550% series), which cut income available to common shareholders by $16 million this quarter and raises preferred dividends going forward.

Did last time's read hold up?

Our Q2 report flagged three things to watch:

• "The provision comparison gets harder... limited room for further release." Wrong so far. Amex released reserves again, taking the reserve ratio down to 2.5% from 2.7% and coverage of past-due balances to 231% from 248%, and that release again carried pretax growth.
• Whether services expense growth decelerates. It did: +36% against +50% in Q2, and the gap between new services cost and new fee revenue shrank from $266 million to $111 million.
• A sizable one-off GBTG gain, which we said would give management room to absorb spending without missing guidance. That is what happened: $982 million booked, $336 million of it spent on restructuring.

Guidance and outlook

Management raised full-year 2026 EPS guidance to $18.30–$18.60 GAAP, or $17.60–$17.90 adjusted, and says it is "on track to deliver another year of 10 percent revenue growth" (year-to-date revenue is +10%). Against the previous $17.30–$17.90 range, the underlying raise is only to the bottom end: the top is unchanged and the midpoint moves from $17.60 to $17.75. The rest of the gap between the GAAP and adjusted ranges, about $0.70 a share, is the net effect of the GBTG gain and restructuring.

Year-to-date adjusted EPS of $13.49 implies $4.11–$4.41 in Q4, against $3.53 in Q4 2025, a quarter that carried $1.41 billion of credit provisions. That is 16–25% growth against an easy comparison.

Our read: the demand side is in good shape. Spending is up 8%, fees per card 14%, write-offs are falling, and the Platinum cost step-up laps in Q4. But for a second straight quarter, profit growth has come from places that don't repeat: a reserve release in both quarters, plus a lower tax rate and a one-off sale this time. Q4 is the test. With the services-expense comparison easing and a weak Q4 2025 as the base, the operating business should show growth without help from reserves. If it doesn't, the 2026 numbers will have been built more on credit and tax than on the card franchise. Also watch the size of the legal-reserve increase and where the restructuring savings show up, both of which should be in the 10-Q.
