United cuts its 2026 profit forecast by about a third: the $4.80 fuel assumption behind it

United Airlines reported record third-quarter revenue on Tuesday and, in the same filing, told investors that fuel will take most of the profit out of the fourth quarter. It guided adjusted earnings to $0.50 to $1.50 a share for October through December. CNBC reported that analysts had expected $1.76. In July United had said it expected $9 to $11 for the full year; with nine months of earnings already booked, the high end of the new range works out to no more than $7.22.

The number behind the number: one fuel assumption

The headline cut is easy to find. The more useful figure sits in the Investor Update that United furnished with the results (Form 8-K on SEC EDGAR). United assumes fuel will average about $4.80 a gallon in the fourth quarter, based on the Gulf Coast jet fuel forward curve as of October 16. It says every one-cent change in the fuel price moves quarterly earnings by about 2.5 cents a share.

It then does something airlines rarely put in writing: it compares itself to the analysts. Consensus, United says, assumes about $4.35 a gallon, roughly 45 cents lower, and that difference is worth about $1.00 a share. Put simply, if you believed the $4.35 figure, United's guidance would sit near the old consensus. The disagreement is about jet fuel, not about demand.

The arithmetic is United's own. A move from $3.90 to $4.80 is 90 cents, or about 23%. At 2.5 cents of earnings per share for each cent of fuel, a 45-cent gap is 112 cents, which the company rounds to "approximately $1.00".

Demand is not the problem

Third-quarter revenue was $17.9 billion, up 17.4% and an all-time record, with unit revenue up 15.9%. Passengers carried hit a record 49.5 million. Capacity grew only 1.3%, so nearly all of the revenue growth is price and mix: premium revenue rose 17%, Basic Economy 16% and cargo 23%. Fuel expense rose about 62% from a year earlier to $4.84 billion, up $1.8 billion. Adjusted earnings per share of $2.54 were just under the $2.57 expected, according to the CNBC report, which cites LSEG.

United says fourth-quarter revenue growth will accelerate to over 20%. That is consistent with what we have tracked on fares: see Delta's cut to Main Cabin seats for winter and TSA screenings running 2% below last year. Airlines are passing fuel through in fares, but not all of it.

Who it hits

• A travel agency or corporate-travel manager: United reports contracted business revenue up 26%, so companies are paying more for the same seats. Budgets set in the spring are now short.
• A holiday traveler: with capacity nearly flat and revenue growth heading above 20%, the room for discounting is small. See our travel section for fare checks.
• A regional supplier or contractor serving airports: United has 10 new international routes planned for summer 2027, subject to government approval, and a larger Houston and Dulles build-out, and the Investor Update puts 2026 capital spending at about $7.5 billion, so the expansion is going ahead alongside the profit cut.

What to watch

Management discusses the guidance on its earnings call on October 21. The questions that matter are whether the jet fuel curve moves from its October 16 level, and whether United's fare increases hold through the holiday peak. United shares closed Tuesday at $97.77, up 2.27%, and traded at $96.61 in after-hours trading at 6:51 PM ET, according to Nasdaq.com.
