Delta cuts its 2026 guidance: how to read the numbers

Delta Air Lines lowered its profit and cash flow forecasts for 2026 because jet fuel has become much more expensive, CNBC reported. At the same time, its CEO said travelers are still booking. This article uses Delta's release to show how to read three numbers that often move a stock on results day: guidance, adjusted EPS and free cash flow.

The headline in plain words

On Friday Delta said it now expects full-year adjusted earnings per share of $5.10 to $5.60. In July, when fuel was cheaper, it had guided to $6.50 to $7.50. In July it had expected free cash flow of up to $4 billion for the year; the new figure is $2.5 billion. Its forecast for the fourth quarter came in below what analysts expected.

In short, the company expects to earn less this year than it said three months ago. The reason it gives is cost, not a lack of customers.

The number behind it: guidance

Guidance is a company's own forecast for a future period, usually given as a range. It is not an audited figure. It is management's best estimate, and it can be changed at any time. When a company moves its range, the size and direction of the change often matter more to the market than the quarter that just ended.

To read a guidance change, put the old and new ranges side by side. For Delta, the old range was $6.50 to $7.50 per share and the new one is $5.10 to $5.60. The whole new range sits below the bottom of the old one. That is a clearer signal than a range that only moves at one end.

Three other figures sit next to guidance in most releases:

• Net income and EPS: the profit under standard accounting rules, divided by the number of shares for EPS. In the third quarter Delta earned $756 million in net income, which is $1.15 per share, a 47% fall. A year earlier the figures were $1.42 billion and $2.17 per share.
• Adjusted EPS: the same idea, but with one-time items removed. CNBC corrected its story to give Delta's adjusted EPS as $1.76. Companies choose what to adjust, so always check what was left out.
• Free cash flow: cash from operations minus spending on equipment and other long-term assets. It shows how much cash the business actually produces, which is why a cut from up to $4 billion to $2.5 billion stands out.

What Delta and the report said

Delta's fuel costs are up $6 billion this year. FactSet data show US Gulf of Mexico jet fuel at $4.34 on Thursday, compared with $2.19 a year earlier. CNBC said the spike began with the Iran war in February. CEO Ed Bastian said Delta is passing much of the extra cost on through higher fares, and that bookings continue. "The consumer response continues to be quite strong."

The revenue lines support that. Operating revenue rose 21% to $20.19 billion. Excluding refinery sales, the maintenance business and profit-sharing, revenue grew 16% to $17.59 billion. Premium revenue rose 18%, reaching $6.82 billion. Main cabin sales grew 12%, reaching $6.8 billion. Delta also guided to fourth-quarter revenue growth of 20%, adjusted for its refinery, faster than the third quarter's 16%. Delta owns a refinery in Trainer, Pennsylvania, which turns crude into jet fuel and other products.

So revenue is growing while profit falls. That gap is the story: costs are rising faster than sales. Based on LSEG consensus figures, it was Delta's first miss against analyst estimates in two years. As the most profitable US airline and the first to report third-quarter results, Delta's results are an early look at the sector, though each airline has its own costs.

Reading revenue and profit together

A common beginner mistake is to look at one line only. Rising revenue can hide falling profit, and a profit drop can hide healthy demand. Reading the two together tells you where the pressure comes from. Here, the higher fares and premium sales show demand, while the fuel bill shows the cost side. Neither line alone tells you what the stock will do next.

How to check this yourself next time

You can repeat this reading with any company's quarterly release.

• Find the guidance table and write the old range next to the new one. Note whether the whole range moved or only one end.
• Compare net income with adjusted EPS, then read the footnotes to see which items the company removed.
• Look at revenue growth and profit change side by side, and check whether the company names a cost, such as fuel, as the reason for any gap.
