Key Highlights

● Full-year Earnings Per Share guidance moved higher while Revenue growth guidance stayed near 10%.

● A large gain on the GBTG stake lifted reported earnings per share.

● Adjusted earnings per share rose by a bit more than a tenth.

● Card member spending grew 8% and a reserve release helped provisions fall.

American Express (NYSE:AXP) raised its full-year earnings-per-share guidance when it reported third-quarter results in late October, citing strong year-to-date performance. The new generally accepted accounting range sits between $18.30 and $18.60, while the adjusted range, which strips out one-time items, is $17.60 to $17.90.

The gap between those two ranges is the heart of the story. The quarter included a large pre-tax gain from the disposal of the company's Equity stake in the Business travel firm GBTG, partly offset by a restructuring charge. Reported earnings per share rose by nearly a third, but the adjusted measure rose by a bit more than a tenth, which is the cleaner read on underlying momentum.

Revenue growth was a bit under 10% and billed business, the measure of spending on the company's cards, rose 8%.

What exactly did American Express raise?

The change was to earnings-per-share guidance, the figure management uses to frame the year. The full-year generally accepted accounting range now spans $18.30 to $18.60, compared with $15.38 in the prior full year, which implies growth of about a fifth. The adjusted range of $17.60 to $17.90 implies growth in the mid teens.

Revenue guidance did not change. Chief executive Stephen Squeri said the company is on track to deliver another year of revenue growth of about 10%, and he tied the earnings increase to performance so far this year.

The guidance matters because Amex has a record of setting ranges that it then meets or exceeds. Raising the range after nine months of results narrows the remaining uncertainty to the fourth quarter, which is typically the seasonally strongest period for card spending.

The release was published in the morning before the market opened, and management discussed it on a call that same morning. Nothing in the release itself describes the fourth quarter in detail, so readers must infer what the range implies for the final three months of the year.

Arithmetic on the ranges shows that the nine-month earnings per share of $14.22 on the reported basis leave room of roughly $4.08 to $4.38 for the fourth quarter, and the adjusted nine-month figure of $13.49 leaves a similar remainder. That is a useful sanity check on how demanding the new range is.

How large was the one-time gain, and why is it excluded?

The company recorded a pre-tax gain of $982 million, about $750 million after tax, from disposing of its equity interest in GBTG, the corporate travel management company. That gain is excluded from adjusted results, as is a restructuring charge of $336 million before tax, about $250 million after tax.

Net of those two items the sum is still a substantial positive, and it explains why reported net earnings rose 28% to about $3.7 billion while adjusted net earnings, at about $3.2 billion, rose 11%. Diluted per-share earnings were $5.42 on the reported basis and $4.68 on the adjusted basis.

Excluding one-time gains and charges is a standard practice, but readers should keep both measures in view. The adjusted figure shows operating momentum, whereas the reported figure shows what actually flowed into the bottom line.

For nine months, reported net earnings were about $9.8 billion, up 17%, with Diluted Earnings per Share of $14.22, up a fifth. Adjusted per-share earnings for the nine months were $13.49, up 14%.

The effect of the gain on the quarter is large enough that comparing the third quarter alone with earlier periods can mislead. The nine-month view, which smooths out some of the noise, shows that adjusted growth has been running in the low to mid teens throughout the year.

What did card spending show?

Billed business, the total Volume spent on American Express cards, reached about $454 billion, up 8% from a year earlier on both a reported and a foreign-exchange-adjusted basis. Over nine months, billed business was about $1.3 trillion, up 9%.

The consistency between the two growth rates indicates that currency was not distorting the picture. It also indicates that the pace of spending has been steady rather than accelerating or decelerating sharply through the year.

Spending drives most of the company's revenue, from discount revenue paid by merchants to the fees and interest connected with card membership. When spending grows at a stable rate, management can plan expenses, including variable customer engagement costs, with fewer surprises.

The release does not give separate figures here for new card accounts or Loan growth, so the spending line is the best indicator of volume in the document. The release does say that net interest revenue grew with card balances, which implies lending to card members is expanding.

Growth of 8% in billed business is solid for a base of this size, and it was achieved without a currency tailwind. That is relevant because a weaker dollar can flatter reported spending for a company with a large international business.

Where did revenue growth come from?

Revenue net of interest expense was about $20 billion, up 9%. Net interest revenue rose 10% to about $4.9 billion on growth in card balances, and non-interest revenue rose 8% to about $15 billion, which comprises discount revenue, card fees and other items.

The company's growth over the nine months was a little faster, with revenue up 10% to about $58.5 billion. Management's statement of an approximate 10-percent annual pace therefore reflects roughly the year-to-date experience.

One outside review pointed out that third-quarter revenue came in a hair below the consensus estimate even as adjusted earnings beat it. The miss was small, but it illustrates that the earnings beat leaned on Credit and tax lines more than on revenue.

Discount revenue is the fee charged to merchants on each transaction, and it tracks spending. Card fees come from annual membership charges and are more stable. Net interest revenue depends on balances and on the rate environment, and its 10% rise shows that card members carried larger balances.

The mix is what distinguishes the company from a conventional bank, since about three-quarters of revenue is non-interest in nature. That makes earnings more sensitive to spending and less sensitive to rate changes than at a traditional lender.

Why did credit costs fall?

Provisions for credit losses were about $1 billion, down from $1.3 billion in the year-ago quarter. The company attributed the decline to a reserve release this quarter compared with a reserve build in the prior-year quarter, partly offset by higher net write-offs.

The net write-off rate on principal was 1.8%, slightly lower than the year before. In other words, actual credit performance was stable to slightly better, and the reserve release reflects management's assessment of the loan book and the economy.

Reserve releases boost reported earnings but can reverse if conditions deteriorate. That is why many readers look at both the provision line and the write-off rate when judging credit quality, and why Squeri's reference to excellent credit quality is a statement about current data.

The year-ago provision included a reserve build, so the comparison is easy. The write-off rate was only a tenth of a percentage point lower, so most of the swing in provisions came from the reserve line.

A reserve release means management believes it set aside more than needed in earlier periods. The size of the release is not itemized in the headline figures, so outside readers usually rely on the allowance and delinquency data in the full filing.

How did the tax rate and share count affect per-share results?

The effective tax rate fell to about 18% from about 24% a year earlier. A lower tax rate lifts net earnings without any change in operating results, and it accounts for some of the divergence between pre-tax and after-tax growth. Pre-tax earnings rose 18% to about $4.5 billion.

Average diluted shares fell by about 3% to roughly 674 million. A smaller share count raises earnings per share even when total earnings are unchanged, and it follows from the company's ongoing program of retiring stock.

Put together, lower taxes, fewer shares and an easing credit line all helped per-share growth outpace revenue growth. These are legitimate contributors but they are of a different character than growth in spending, and they may not repeat at the same scale.

Management also noted that the lower tax rate and the reserve release were both favorable items in the quarter, so a clean comparison with later periods should account for them. Neither is guaranteed to recur.

What did expenses look like?

Consolidated expenses were about $14.5 billion, up 9%. Management attributed the increase mainly to higher variable customer engagement costs, which include rewards, card member services and business development payments, partly offset by lower operating expenses.

That mix is typical for a premium card issuer: when spending rises, rewards and engagement costs rise with it. The restructuring charge in the quarter was excluded from adjusted results and is separate from those variable costs.

Expense growth equal to revenue growth means little Operating Leverage on a pre-tax basis in the quarter, which is why the earnings gains are traced to credit, tax and share count rather than to efficiency gains.

Variable customer engagement costs are the part of the cost base that expands automatically when members spend more. The remainder, operating expenses, fell in the quarter according to the release, which is the portion management can control directly.

Restructuring charges, in contrast, signal that the company is reorganizing some functions. The release lists the charge as an adjustment but does not itemize where it falls.

What growth initiatives did the company point to?

Coverage of the results highlighted several commercial moves, including an exclusive Partnership with a large home-sharing platform that places more than a million listings on the company's travel booking service, an extended co-brand agreement with a major hotel group, and new airport lounges in Amsterdam and Newark.

Those moves fit the company's strategy of offering premium benefits, such as travel perks and lounge access, to justify annual fees. Fees are a significant part of non-interest revenue, and the model depends on cardholders continuing to see value in the benefits.

Readers following Financial Stocks will also see that payment networks and card issuers are competing on perks as well as price, which raises the stakes for each new partnership and for the cost of delivering them.

What uncertainties did the company flag?

The coverage of the report listed macroeconomic and geopolitical pressures, regulation of pricing, and competition from newer technologies and alternative payment methods. These items are part of the standard warning language in the company's filings and are not new.

Pricing regulation deserves special mention for card issuers. Any rule that limits the fees merchants pay or caps card pricing could change the Economics of rewards programs, which is why the company lists pricing regulation among its stated uncertainties.

Alternative payments, including account-to-account transfers and technology-enabled checkout tools, are a longer-term competitive theme rather than a quarter-specific one.

Because these are general statements, they do not point to a specific event on the calendar. Readers who want to judge their relevance should compare the language with earlier filings to see whether the wording has changed, since a new sentence or a removed one is often the most informative signal in a discussion of uncertainties.

How did the market react on report day?

On the regular session after the report, the stock closed lower by under 2%, according to a financial news service summary. Pre-market trading had also dipped on the small revenue miss, though some retail commentators highlighted the guidance raise.

A one-day move says little about the substance of a quarter. The comparison between the guidance change and the revenue figure is more informative, because it shows where the company is getting its earnings growth.

For context, the stock is a component of the S&P 500 and the Dow Jones Industrial Average, and large-cap financial names have reacted to earnings releases with a wide range of price moves this season.

What should readers watch next for American Express?

The first item is the fourth quarter, when holiday spending typically lifts billed business. The company has set its full-year ranges with that period in mind, so the final quarter will test how conservative or ambitious they were.

The second is credit. If the reserve release proves a one-time event, provisions could rise in subsequent periods even with stable write-offs. The third is expense discipline, because variable engagement costs have been growing as fast as revenue.

Finally, regulatory and competitive news could shift the picture without notice.

Another item is Capital deployment. The lower share count shows that the company has been retiring stock, and quarterly dividends continue, but the release did not provide figures on either, so those details will come from the quarterly filing.
