Is Booking’s Slowdown A Pause Or Its New Pace

Booking (BKNG) turns 35% of its sales into operating profit, against 18.6% for the S&P 500. Yet its stock lost 29% in the year to September 23, 2026, while the index returned 13%. Booking expects third-quarter 2026 revenue to grow just 4% to 6%. The question you face is whether that slower growth is a pause or Booking's new pace. Start with what the current price already asks you to pay.

What Are You Paying For Booking's Profits?

You pay 16.6 times Booking's yearly profit, well below the 22.4 times for the S&P 500. This ratio is called the P/E. It is the share price divided by one year of profit per share. So it shows what each dollar of earnings costs you.

That multiple did not come from a shrinking business. Its sales over the past twelve months were $28.2 billion, against $25.0 billion a year earlier. That is a rise of about 13%, in a year when the stock fell.

Booking's Quarterly Revenue Growth Has Slowed To Single Digits

Booking's revenue grew 13.5% a year on average over the past three years, against 5.8% for the S&P 500. In the latest quarter, revenue grew 8.1% from a year earlier. Management said elevated cancellations in March affected second-quarter revenue and held back its growth. Booking's third-quarter guidance of 4% to 6% would be slower again.

Management tied the weaker outlook to the conflict in the Middle East. Higher airline prices and fewer flights on some routes have held back long-haul international travel. The guidance assumes those effects last through the third quarter.

Booking also lowered its full-year expectation for gross bookings, the total value of trips booked through its sites. The main reason was lower flight ticket growth. Its accommodation outlook stayed largely unchanged. If flights are the main drag, the next question is what Booking can do on its own while it waits.

Booking Is Buying Back Its Own Shares Fast

Booking spent $7.4 billion buying its own stock in the first half of 2026. It paid about $173 a share on average. The latest price of $155.9 is below that level. In the second quarter, Booking also raised $3 billion of debt and paid down $1 billion.

When a company retires shares, each remaining share owns a bigger slice of the profit. In the second quarter of 2026, the average share count was 6% lower than a year earlier. That helped adjusted earnings per share rise 15%, faster than the 9% rise in adjusted EBITDA, a broad profit measure. So even with slower growth, each share you hold claims more of Booking's profit. Those buybacks pay off only if Booking keeps winning travelers without paying much more to reach them.

Is Booking Paying More For Its Web Traffic?

Yes, a little more. Booking's marketing expense rose 11% in the second quarter of 2026, modestly faster than gross bookings. Management said the cause was changes in where its traffic comes from.

On the same call, management said changes in Google's display have pressured free search traffic. In management's view, Google's AI overview probably played a part. Free search traffic means visitors who arrive from unpaid search results. Management added that unpaid search is only a small part of Booking's traffic, and its direct traffic has held steady. If more visitors must be paid for, marketing costs could keep growing faster than bookings.

The thing to watch is Booking's next report, for the third quarter of 2026. Growth near the top of the 4% to 6% range, with accommodation holding up, would suggest flights caused the slowdown. Marketing expense growing no faster than gross bookings would ease the traffic worry. Revenue growth below 4%, with accommodation weakening too, would point to a slowdown that runs deeper than air travel.
