Booking's Operations Re-Accelerated While Its Stock Fell 25%: Upgrading to Outperform Through a $1 Billion FTC Charge and a Flat Fourth Quarter

Results vs. Consensus

Q3 2026 Scorecard

Consensus revenue is set on the adjusted basis, which excludes the FTC reduction. Several early headlines compared the $9.55 billion Street figure with GAAP revenue of $8,893 million and called the quarter a revenue miss. On a like-for-like basis it was a 2.5% beat.

Versus the Company's Own Guidance

The guided range of 4% to 6% revenue growth implied $9,368 million to $9,548 million, and the Street sat at its very top. Booking cleared it by about $245 million. This is now four quarters out of five in which every guided line has landed above the high end.

Year-Over-Year Comparisons

The GAAP lines carry two large items that point in opposite directions. Q3 2026 absorbed the $1.0 billion FTC charge, $900 million in revenue and $100 million in general and administrative expense. Q3 2025 had absorbed the $457 million KAYAK impairment and $105 million of transformation costs. That is why GAAP operating income fell 1.9% while adjusted EBITDA rose 8.9%. The adjusted figures are the right read of the operating quarter. The FTC charge is the right read of a liability that management has stopped contesting, and we treat it as a real cost below.

Growth Trajectory: Five Quarters

Booking's quarters are too seasonal for a sequential comparison to mean much, so the table below tracks year-over-year growth by quarter. Q3 2026 is the only quarter of the five in which room nights, constant-currency gross bookings, constant-currency revenue and flights all accelerated together.

First Nine Months of 2026

Revenue

Adjusted revenue of $9,793 million grew 8.7%, or about 10% in constant currency, and exceeded the high end of guidance by about 2.7 points. Gross bookings grew 9.6% and adjusted revenue grew a little slower. Management attributed the gap to a higher mix of flight bookings, which carry a lower take rate, and to the timing of bookings versus travel, partly offset by payments revenue.

"Adjusted revenue as a percentage of gross bookings was about 15 basis points lower year-over-year due to a higher mix of flight bookings and the timing of bookings versus travel, partially offset by higher revenues from facilitating payments." — Ewout Steenbergen, CFO

Constant-currency ADRs rose about 3%, the best pricing reading in our coverage, led by Europe and supported by the U.S. and Asia. Alternative accommodations recovered to 7% growth from 4%. Higher ADRs and flights, which grew 19.4% in units and 21% in gross bookings, explain the four-point wedge between constant-currency gross bookings and room nights.

Assessment: Constant-currency revenue growth of about 10% answers the question we left open in August, when 7% was the first print below the company's own "at least 8%" floor. One quarter at 10% does not establish a trend, and the Q4 guide of 2% to 4% in constant currency will interrupt it. But it shows the Q2 slowdown came from the Middle East conflict and flight capacity, not from the core.

Margins

Adjusted EBITDA margin held at 47.0%, up 7 basis points. Adjusted fixed operating expenses grew 6.4%, with personnel slightly down year over year, and adjusted sales and other expenses fell to 2.0% of gross bookings from 2.1%. Third-party customer service costs declined on AI-assisted tools despite higher volumes. Marketing rose 10.6% against 9.6% gross bookings growth, so the total ratio rose to 4.8% from 4.7%. Information technology grew 24.8% on cloud computing, software licenses and generative AI costs.

"Excluding our B2B affiliate business, our B2C business had marketing leverage in the quarter as we continue to aim to grow our topline metrics faster than marketing investments." — Ewout Steenbergen, CFO

Assessment: B2C marketing leverage arrived nine months after management promised it, and that matters for the bear case on customer acquisition costs. The offset is that the savings are being reinvested: Q4 EBITDA is guided flat on "increased planned investments," and the full-year margin is guided stable rather than higher. The margin is holding, not expanding.

EPS and Cash Flow

Adjusted EPS of $4.66 grew 17.1% and beat consensus by $0.17. The average diluted share count fell 7.5% to 753 million, the largest reduction in our coverage window, and that carried roughly nine of the seventeen points of growth. GAAP EPS of $3.61 grew 6.8% despite the FTC charge, because net income was nearly flat and the share count fell.

Free cash flow of $1,069 million fell 22.0%. The third quarter is when deferred merchant bookings unwind after the summer, and the unwind was $3.6 billion this year. Nine-month free cash flow of $7,820 million grew 2.0%. Cash and investments ended at $16.2 billion against $17.7 billion at the end of June. The $1.0 billion FTC liability sits in accrued expenses and has not been paid.

Assessment: The per-share algorithm is now about half buyback. That is a legitimate source of return, but adjusted net income growth of 8.3% is the true operating growth rate. The FTC payment, about 11% of FY2025 free cash flow, will reduce repurchase capacity when it is paid.

Segment Performance

Revenue by Type

Merchant and Payments

Merchant gross bookings of $40.7 billion grew 13.9% and reached about 75% of total gross bookings, up about three points. The growth rate was essentially unchanged from Q2's 14.5% after falling from the mid-20s, which is the arithmetic of a high base. Management positioned the payments platform as the enabler of the Connected Trip, since one checkout across verticals requires Booking to hold the payment.

"Our merchant payments platform is a key enabler of our Connected Trip vision, providing travelers with a more seamless and flexible booking experience, helping partners accept customers' preferred payment methods, and generating incremental contribution margin dollars for our business." — Ewout Steenbergen, CFO

Assessment: At 75% the merchant migration has about a quarter of the book left to convert. The ceiling we flagged in August is holding, but merchant revenue still grew 14.1% and is doing most of the work in adjusted revenue growth. We continue to model the payments tailwind to take rate fading over roughly two years.

Agency

Agency revenues fell 4.1%, narrowing from Q2's 6.9% decline, and agency gross bookings fell 1.3% against a 3.3% decline in Q2. In August we flagged that agency revenue was falling faster than agency bookings, a possible sign of commission compression. The gap narrowed this quarter but did not close.

Assessment: A modest improvement. The decline remains consistent with mix migration to merchant rather than with pricing pressure, and we no longer treat it as a watch item.

Advertising and Other

Advertising and other revenues grew 7.8% to $332 million, in line with Q2's 8.4%. The line holds KAYAK's search advertising and OpenTable, and OpenTable now had the most visible AI news of the quarter: its native OpenAI integration is "one of the brand's fastest growing channels," with 190,000 seated covers in September, and it was the first dining partner on Meta's Muse.

Assessment: Steady growth from the portfolio's most search-exposed assets in a year of falling SEO traffic is an acceptable result. KAYAK has now gone four quarters without a word since the $457 million impairment, which makes the silence a disclosure in its own right.

Key KPIs

Assessment: In August every vertical attached to the accommodation core had slowed at once. This quarter every one of them re-accelerated, and rental cars, the one we said had no explanation, narrowed its decline to under 1%. The release also added a second direct-mix figure. The mid-fifties figure includes B2B room nights and was the same a year ago, while the B2C figure the company has always cited held in the mid-60s. Neither shows erosion.

Geography and the Domestic/International Split

The international recovery we expected in August arrived, though only part of the way. International room nights grew mid-single digits after growing only slightly in Q2. Domestic room nights grew high single digits, unchanged. By booker region, Europe grew high single digits with domestic high single digits, Asia grew high single digits with domestic low double digits, and Rest of World grew mid-single digits, stable with Q2 as Middle East bookers kept growing.

The United States grew mid-single digits, led by domestic travel, with another quarter of direct-channel growth. That is a second consecutive step down, from low teens in Q1 and high single digits in Q2. The booking window contracted modestly in the U.S. while it lengthened slightly in Europe and globally.

Assessment: Europe and Asia did the work this quarter, which fits a business recovering from a long-haul aviation shock. The U.S. is now the soft spot. Management repeated that it has outgrown the U.S. market for three years, but it gave no explanation for a two-quarter slide from low teens to mid-single digits in its most important growth market. We would want that explained by February.

Key Topics & Management Commentary

Overall Management Tone: Management was confident on the quarter, cautious on the near term, and expansive on AI, which took up most of both the prepared remarks and the Q&A. The tone on the fourth quarter was more guarded than in August: the planning assumption moved from a fading conflict to one that persists through year-end, and the investment step-up was framed as discipline rather than explained in size. The least convincing part of the call was what it left out. A $1 billion charge in the release drew no comment from management and no question from the analysts.

1. A $1 Billion FTC Charge, Disclosed Only in the Filings

In July the FTC staff told Priceline they intended to recommend a complaint against Priceline and one of its B2B affiliate partners, asserting unfair or deceptive practices on disclosures, fees, customer support and billing. In the August 10-Q Booking wrote that Priceline "does not agree with the FTC's position." The November 10-Q drops that sentence. Booking now expects a negotiated resolution and has reduced Q3 revenue by $900 million and accrued a $100 million loss.

"Although a settlement has not been agreed and litigation remains possible, a negotiated resolution would be likely to include an agreement by Priceline to pay a certain amount to the FTC directly as well as to provide monetary restitution to certain U.S. consumers, in addition to a commitment by Priceline to change certain of its business practices." — Booking Holdings, Q3 2026 Form 10-Q

The accounting tells its own story. Booking booked the $900 million as a reduction of revenue, the treatment for money returned to customers, and the $100 million as an expense. The filing adds that the FTC "may seek monetary penalties and restitution in excess of these amounts," and that similar claims could follow in other jurisdictions. For scale, $900 million equals 3.3% of FY2025 revenue for the whole group. Our August note did not flag the July notice, and it should have.

Assessment: The amount is affordable. It equals about 11% of FY2025 free cash flow and comes out of a $16.2 billion cash balance. What we cannot yet size is the commitment to change business practices. If the practices at issue produced fee revenue, Priceline's revenue line will be lower after settlement, and management has not said whether the guide reflects that. We add a regulatory bear point this quarter. This is the main reason we trim the valuation multiple rather than hold it.

2. The Fourth Quarter Is Guided Close to Flat

Management guided Q4 room nights to grow 1% to 3%, gross bookings 2% to 4% (4% to 6% in constant currency), adjusted revenue 0% to 2% (2% to 4% in constant currency) and adjusted EBITDA about flat. Three things drive it. Demand moderated late in Q3 on international travel. October brought disruption to travel to and from the Middle East, higher airfares, and unrest in some European cities. And Q4 laps the toughest comparison of the year, room nights +9.0% in Q4 2025.

"Moving to our thoughts for the fourth quarter, the travel environment is mixed. As I mentioned earlier, we saw some moderation in global demand trends toward the end of the third quarter, driven by international travel. Domestic travel continues to hold up as we are seeing travelers take shorter trips and choose destinations closer to home." — Ewout Steenbergen, CFO

The planning assumption changed. In August the guide assumed the indirect effects of the conflict would persist through Q3. The new guide assumes "both the direct and indirect impacts of the Middle East conflict on travel persist through the end of the year." Currency adds a two-point drag on reported growth, with the euro assumed at $1.12 against $1.15 in August.

Assessment: The guide is weak, and it reflects real events rather than caution alone. A roughly four-point miss against the Street at the midpoint is large for a company that has beaten its high end four times in five quarters. We still read most of it as exogenous: currency is two points, the comparison is the hardest of the year, and October's disruptions are tied to specific events. The pattern of guiding low and beating high should also continue. A Q4 room-night print below 1% would change our read.

3. The Investment Step-Up Behind a Flat EBITDA Guide

The fourth-quarter EBITDA guide is weaker than the revenue guide. With adjusted revenue up 0% to 2%, EBITDA is guided about flat because Q4 carries more planned spending on non-accommodation verticals, AI and technology infrastructure.

"We currently expect adjusted EBITDA to be about flat year-over-year, or up about 2% on a constant currency basis, and to be impacted by increased planned investments behind our long-term strategic priorities, including expanding capabilities across non-accommodation verticals such as flights, attractions, and dining; advancing our AI capabilities; and enhancing our underlying technology infrastructure and platforms." — Ewout Steenbergen, CFO

The full-year EBITDA margin is guided "stable," which our arithmetic confirms at about 36.9%. In February the plan had been about 50 basis points of expansion, cut to 0 to 25 basis points in April. Asked about 2027 investment, management deferred to February and stressed it would "stay disciplined." It did not size the Q4 step-up, and it did not say whether the spending continues into 2027.

Assessment: This is the item most likely to move 2027 numbers. Transformation savings of about $650 million and B2C marketing leverage are being reinvested, not dropped to EBITDA. We assume part of the Q4 run-rate carries into 2027, and that is one reason our FY2027 estimate falls.

4. Room Nights Re-Accelerated on International Travel

Room nights grew 6.7%, up from 5.3%, and cleared the high end of guidance by about 1.7 points. The improvement came from international travel by European and Asian bookers. Domestic room nights grew high single digits, unchanged from Q2.

"Room nights grew 7%, up from the 5% in the second quarter, driven by an improvement in international travel from bookers in Europe and Asia, while domestic room night growth was stable at a higher level." — Ewout Steenbergen, CFO

Average length of stay rose outside Asia, and Asian domestic travel outgrew Asian international travel by the widest margin of any region. Booking.com had about 4.7 million properties at quarter-end, up from 4.4 million a year earlier.

Assessment: The core accommodation engine was never the problem in Q2, and it confirmed that in Q3. The U.S. slowdown to mid-single digits is the exception and is discussed above. Q4's 1% to 3% guide is the low point of the year by design.

5. Every Connected Trip Vertical Sped Up

In August we scored the Connected Trip pillar AT RISK, because flights, rental cars, attractions and alternative accommodations had all slowed at once. This quarter they all turned. Flight tickets grew 19.4% from 3.7%, attraction tickets 24% from double digits, alternative accommodation room nights 7% from 4% with listings up 9%, and rental car days declined 0.7% against 6.5%.

"Importantly, Connected Trip transactions' growth accelerated to almost 20% year-over-year, and represented a low double-digit mix of Booking.com's total transactions." — Ewout Steenbergen, CFO

Flights grew "ahead of the broader market" despite high fares and reduced capacity on some routes, and the 10-Q credits the expansion of Booking's flight offering. Rental cars were not discussed. The 10-Q attributes the decline to "lower partner volume" plus higher daily rates and the conflict.

Assessment: The pillar moves from AT RISK back to ON TRACK in one quarter, the same one-step move Bull #1 made in August. We said in August that only one of the four slowdowns had a satisfying explanation. The rebound across all four suggests more of the slowdown was exogenous than we allowed. Connected Trip growing about three times faster than Booking.com transactions, at a low double-digit mix, is the frequency engine the bull case requires.

6. LLM Referrals Accelerated, and Still Arrive at Booking

The number we asked management to track every quarter moved for the first time. Referrals from large language models "accelerated over the last several weeks," with organic referrals rising after new ChatGPT models improved citation rates and paid referrals growing as Booking expands its OpenAI partnership into more markets. The share is still "significantly less than 1%" of Booking.com's room nights.

"LLM referrals have accelerated over the last several weeks but still account for significantly less than 1% of Booking.com's room nights. Organic referrals increased following the release of the latest ChatGPT models, which improved citation rates and drove more traffic to our platforms." — Ewout Steenbergen, CFO

In Q&A management added that the newer agents show no divergence in growth, and that third-party data show the "vast majority" of LLM travel traffic reaching Booking.

Assessment: This fires one of the Underperform triggers we set in August, evidence that the LLM referral share has begun to inflect, and we treat it seriously. We explain how it nets in the valuation section. The direction of the traffic matters, though. These referrals send users to Booking rather than keep them inside the model, and they come from a base still well below 1%. The risk is not that the number is growing. The risk is that agents start to complete bookings themselves, and that is the next topic.

7. Booking Joins Meta's Muse Through Agoda and OpenTable

The sharpest leg of the stock's decline came in September. The shares fell 7.5% over September 22 and 23, including 5.1% on the 23rd, as two events landed together. Expedia announced a partnership that lets users of Meta's Muse assistant plan and book through Expedia without leaving the assistant, and the EU General Court upheld the block on Booking's acquisition of ETraveli. Booking answered on this call. Agoda is live on Muse as a launch partner in Asia, OpenTable is Muse's first dining partner, and Booking named Meta, OpenAI, Google and Amazon among its AI partners.

"OpenTable's native integration with OpenAI has become one of the brand's fastest growing channels, from a small base, and OpenTable recently debuted as the first dining partner with Meta's Muse personal agent. And Agoda is live on Muse as a launch partner in Asia, connecting Muse directly with Agoda's new AI assistant." — Glenn Fogel, CEO

Booking also launched two AI-native experiments outside its main brands: Lola, a conversational travel, dining and events service with a membership model, and Vayo, a proactive AI travel agent that imports past reservations from a user's email. Management called both "testing grounds" and gave no metrics.

Assessment: Booking is now on both sides of the agent question: it supplies inventory to horizontal agents and builds its own. The strongest argument for the supplier role is economic. An agent that wants real-time price and availability for 4.7 million properties is cheaper to connect through an aggregator than property by property. The unanswered question is the take rate on an agent-completed booking, and no company in the industry has yet disclosed one.

8. The First Top-Line Evidence From AI

After four quarters of declining to quantify AI's revenue effect, management gave four indicators: daily AI search visitors at Booking.com up 10 times quarter over quarter, AI-assistant users at Priceline and Agoda converting at about twice the rate of non-users, Agoda AI-assistant users booking about 20% more value, and new customers arriving through OpenTable's agent integrations.

"Second area is higher conversion. So a couple of examples, again, Priceline's Penny and Agoda's AI Assistant users have converted at approximately twice the rate of non-users. Third area, higher booking value. We see Agoda's AI Assistant users have an average booking value of approximately 20% higher than non-users." — Ewout Steenbergen, CFO

On costs, Agoda's blended cost per million AI tokens fell more than 25% between June and September through price caps and model routing. Company-wide cost per merge request fell by double digits, and customer service costs declined despite higher volumes.

Assessment: These are the first numbers on the revenue side, and they come with a caveat. Users who choose an AI assistant are likely to be more engaged travelers, so a twofold conversion gap is partly self-selection. The cost evidence is stronger, because it shows up in reported lines: sales and other expenses levered and personnel was flat.

9. B2C Marketing Leverage, Nine Months Late

In February management committed to marketing leverage in 2026, and it missed in Q1 and Q2. In Q3 the B2C business delivered it. The total ratio still rose, to 4.8% of gross bookings from 4.7%, because B2B affiliate commissions grew faster. The 10-Q also cites "declines in SEO" and warns that SEO traffic will keep falling "in the short to medium term, which may lead to increased spend in paid marketing channels."

"We see 2 advantages there flowing through. One is we're always trying to drive up higher ROIs in our paid channels. And then also what we are seeing is that the direct traffic is up at the same time. So both in combination are helping us to achieve B2C marketing leverage in the third quarter." — Ewout Steenbergen, CFO

Assessment: The commitment was met in the part of the business it was meant for. The B2B deleverage is benign if the affiliate revenue it pays for grows as fast, which management says it does. The SEO warning in the filing is the more durable concern. It is the clearest written statement yet that organic search is shrinking and paid spend may have to replace it.

10. B2B Will Be Combined on January 1, and Probably Disclosed

The B2B consolidation announced in August launches on January 1. Management said the combined unit will "most likely" be reported separately. That would give investors the first sizing of a business that has been credited with U.S. growth for several quarters.

"I think you know about our plans that we're launching on January 1, a combined B2B business. So you will also see then more details about the numbers because most likely, we will break that out going forward." — Ewout Steenbergen, CFO

Assessment: A breakout would answer a question we have raised for three quarters. It would also let investors separate B2C margins from B2B, which pays affiliates through the marketing line. We expect the disclosure to show B2C margins higher than the consolidated figure.

11. The Buyback Slowed as the Stock Fell

Booking repurchased $2.1 billion in Q3, down from a record $3.7 billion in Q2, and returned $2.4 billion in total. The 10-Q shows 11.5 million shares bought at an average of about $182: $181 in July, $205 in August and $175 in September. Nine-month repurchases reached $9.5 billion, and $12.4 billion of authorization remains. The average diluted share count fell 7.5%.

"During the first nine months of 2026, we returned $10.5 billion of capital to shareholders, including $9.5 billion of share repurchases." — Ewout Steenbergen, CFO

Assessment: The slower pace is a puzzle. The company bought less stock in a quarter when its shares fell sharply, and September's purchases, at about $175, were the cheapest of the quarter. Seasonal cash timing and the pending FTC payment are plausible reasons, but management gave none. Even at the slower rate, the share count is falling fast enough to add roughly six points or more to EPS growth.

12. An Early, Positive Read on 2027

Management will give its 2027 framework in February. Asked about it, the CFO volunteered one forward datapoint, explicitly subject to cancellations: bookings already on the books for the first half of 2027 look "healthy." The long-term ambition of at least 8% constant-currency growth in gross bookings and revenue and 15% in adjusted EPS was reaffirmed, and the full-year 2026 guide is "broadly in line" with it at the high end.

"Maybe one thing to throw out for 2027, and this is not related to cost, but more on the commercial side. It's a very early directional indicator. So it's still subject to change, like cancellations and others. But if you look at our on-the-book statistics for the first half of 2027, that actually looks healthy. So that gives us confidence in the outlook for next year." — Ewout Steenbergen, CFO

Assessment: Volunteering an on-the-books read signals that management sees Q4 as an air pocket rather than a new trend. We give it modest weight because it was hedged and not quantified, and because the investment question for 2027 is still open.

Guidance & Outlook

The full year was held on every line except constant-currency revenue, which was narrowed to the top: high single digits, from mid to high single digits. The fourth quarter absorbs the difference. On the Q4 2025 base of $6,349 million, the adjusted revenue guide implies $6,349 million to $6,476 million, and flat EBITDA implies about $2,195 million.

Implied Q4 ramp: Nine-month adjusted revenue of $22,677 million plus the Q4 range gives $29.0 billion to $29.2 billion for the year, growth of 7.8% to 8.3%, inside "high single digits." Adjusted EBITDA of about $10.7 billion would be up about 8.1%, with a margin near 36.9%, the same as FY2025. Full-year room nights would grow about 5%.

Street at: Before the print the Street expected Q4 gross bookings growth of about 7%. Single-source estimates put Q4 room nights at about 5.9%, revenue near $6.80 billion and adjusted EPS at about $2.31. The guide sits about four points below on volume, and the revenue midpoint of $6,412 million is about 5.7% below. Q4 estimates will come down. Full-year estimates should move much less, because the Q3 beat offsets most of the cut.

Guidance style: Conservative, with a record to match: every guided line has cleared its high end in four of the last five quarters. That record is the best argument that Q4 lands above 0% to 2%. It does not cover the investment step-up, which is a decision rather than a forecast.

Analyst Q&A Highlights

Whether AI Has Produced Any Measurable Top-Line Benefit

The call opened with the question management has declined for four quarters: is there quantitative evidence that AI improves conversion or frequency? This time the CFO answered with four categories of indicators, from engagement to incrementality, each with an example.

Q: "Just first on the tangible AI progress that you're seeing in brands. Obviously, good to see the customer service cost efficiencies. Is there anything that you can share in terms of some of the top line benefits perhaps that you're seeing around either conversion rates or frequencies or just other ways to quantify?"
— Douglas Anmuth, JPMorgan

A: "So 4 key areas where we see improvements and really positive indicators, higher engagement, higher conversion, higher booking value and incrementality. It's early days, but we're encouraged by the momentum, and we really think these are really nice positive uplifts on these metrics."
— Ewout Steenbergen, CFO

Assessment: A real change in disclosure. The numbers are cohort comparisons rather than controlled tests, so they overstate the causal effect, but management has moved from declining to give percentages in August to giving them.

Whether the Newer Agents Behave Differently From Earlier Models

The follow-up asked whether the acceleration in referrals came from the new personal agents rather than the established chatbots. Management said no agent stands out, repeated that the total is below 1%, and stressed that most of the traffic comes to Booking.

Q: "And then on those accelerating AI referrals in recent weeks, are you seeing any differences in some of the newer agents like Muse and Grok Bot relative to what you saw previously with kind of the other LLMs?"
— Douglas Anmuth, JPMorgan

A: "So nothing is really jumping out there in terms of one that is growing faster than another. So it's still very small. Yes, we have seen some acceleration in the recent weeks, but it's still significantly below 1%. I also would like to point out that the vast majority of that traffic is coming to us, and that is based on third-party data sources."
— Ewout Steenbergen, CFO

Assessment: The answer is reassuring on share and silent on economics. The statement that "the vast majority of that traffic is coming to us" means Booking is winning the channel. It does not tell us what the channel will cost once the agents decide how to monetise it.

Whether Agents Favour Hotels' Direct Sites Over OTAs

A question raised the concern that agents might route travelers to hotel websites rather than to intermediaries. The CEO said he sees evidence pointing the other way, and argued that independent properties, which supply most of Booking.com's room nights, need an intermediary to be visible to an agent.

Q: "A couple on agentic. I think in addition to economics, one of the concerns is they might be preferencing direct sites versus OTAs. Are you seeing any evidence of that?"
— Justin Post, Bank of America

A: "So it's interesting you say that because I haven't -- I've heard some of that, but I see other things, too, where the OTAs are actually getting a greater advantage right now."
— Glenn Fogel, CEO

Assessment: An assertion without data, but the structural point behind it is sound. The ten largest hotel chains account for only a low double-digit share of Booking.com's room nights, and the long tail of independents is exactly the supply an agent cannot aggregate on its own.

What the Fourth-Quarter Cost Increase Means for 2027

The same questioner asked how the Q4 investment step-up should be read for 2027 and the long-term algorithm. The CFO defended fully loaded margins, deferred 2027 to February, and then volunteered the on-the-books datapoint for the first half of 2027.

Q: "And then second, just thinking about the cost increases in Q4. I think there's some questions on how you're thinking about investment in '27 and what that could do to your algorithm. Any help with that would be very helpful."
— Justin Post, Bank of America

A: "So with respect to 2027, it's a bit too early to provide commentary. We'll do that in February with our fourth quarter results. But what I can say is that we remain confident with respect to our long-term growth outlook, and we will stay disciplined how we are planning to invest in the business also next year and in the future."
— Ewout Steenbergen, CFO

Assessment: The question went unanswered on cost, the part that matters for 2027 margins. The positive bookings read was offered in its place. We take both at face value: demand into 2027 looks fine, and the spending level is undecided.

What Is Driving B2B Marketing Deleverage

A question on B2B marketing deleverage, now visible for several quarters, produced the most useful structural disclosure of the call: the combined B2B unit launches January 1 and will most likely be reported separately. The CFO explained the deleverage as revenue-share commissions to affiliates rising with volume.

Q: "And then the marketing deleverage in B2B. And I think that's been the case for a quarter or 2 or 3. I think you're leaning into this as a channel. Could you talk about any signs of traction, success, more momentum you're getting just in the B2B segment?"
— Mark Mahaney, Evercore ISI

A: "What is happening there is if the business is growing and they are reporting more revenues, usually the commission structures are based on a rev share. So therefore, also the rev share and the commissions are going up, and that is flowing through the marketing line."
— Ewout Steenbergen, CFO

Assessment: The explanation is mechanically correct and makes the total marketing ratio a poor guide to customer acquisition costs. It also means the FTC matter, which involves a B2B affiliate partner of Priceline, sits inside the channel the company is about to expand.

Why Booking Shows Up Inside the Agents

A question noted that Booking appears consistently in Muse search results and asked why. The CEO said there is "no handbook" for agent visibility and credited content quality. The CFO gave the economic answer.

Q: "So in other words, when we do our searches on Muse, we see Booking show up, whether we're looking for a hotel in Panama City, Panama or in Paris, for example. And so Booking inherently is always there. And I think that's because of the supply, but I wanted to get your thoughts there."
— Ron Josey, Citi

A: "As I said before, they like to partner with aggregators. It's going to be very expensive for them to connect to 4.7 million properties directly and get all the information about real-time data, pricing, availability, so they can get that through us and immediately have also the possibility in the future of a potential monetization model with us."
— Ewout Steenbergen, CFO

Assessment: This is the core of the bull case on agents, stated plainly. It argues that agents need Booking's supply. It does not settle who keeps the margin, and the CEO's follow-up, that an agent monetisation model like Booking's own would leave Booking "even in a better position," remains a hope, not a contract.

Whether European Regulation Changes the Agent Picture

A question on the Digital Markets Act's effect on Google's travel results drew a short answer, no visible benefit yet, and then an unprompted argument: European rules may slow the adoption of horizontal personal agents more than investors expect.

Q: "And then sat over here in Europe, we have obviously and specifically Continental Europe, seen the DMA impact on Google's search results, which have thrown a bit of a spanner on what they can display when people search for travel. I wonder if you could give us some thoughts on that and how it might affect your numbers."
— Alex Brignall, Redburn Atlantic

A: "I think there's parts of the world where the adoption of these horizontal personal agents may be much slower than is anticipated. And we'll see what that may mean. For ourselves, we don't know, but it is interesting that I don't see a lot of people talking about that."
— Glenn Fogel, CEO

Assessment: A fair point and an under-discussed one, since Europe is Booking's largest region. It also cuts both ways. The same body of European law opened a Digital Services Act investigation into Booking.com in October, which the CEO did not mention.

Whether AI Efficiency Could Lift the 15% EPS Ambition

The second-to-last question asked whether AI-driven cost savings could push EPS growth above the long-term 15% ambition without faster revenue growth. Management declined to change the framework.

Q: "As AI begins to drive real efficiencies across customer service, across engineering, across other parts of the cost base, does 15% still seem like the right long-term sort of EPS algorithm?"
— Benjamin Black, Deutsche Bank

A: "I think it is a little bit too early to tell you exactly how we will see that changing our long-term algorithm. But what I can say is that we're already moving from experimentation to measurable operating value across the company coming from AI."
— Ewout Steenbergen, CFO

Assessment: The right answer in a quarter guided to flat EBITDA. The savings are real, but management is reinvesting them, and that choice is why the algorithm is not moving up.

What They're NOT Saying

1. The FTC matter, at all: A $1.0 billion charge, the largest item in the release, drew no comment from management and no question in Q&A. The terms are in the 10-Q only.
2. What Priceline's practice changes will cost: A settlement is expected to include "a commitment by Priceline to change certain of its business practices" on disclosures, fees and billing. If those practices generated fee revenue, management did not size the run-rate effect or say whether the guide includes it.
3. The EU's Digital Services Act investigation: Opened in October into Booking.com's platform disclosures and security, and disclosed in the 10-Q. The CEO cited European digital rules as a brake on horizontal agents but did not mention the case against his own platform.
4. The size of the Q4 investment step-up: It moves Q4 EBITDA from growing with revenue to flat. Management named the categories but gave no dollar amount and said nothing on whether it continues into 2027.
5. October in numbers: In April management quantified March precisely. This time October's disruptions were listed but not measured, and the Q4 guide cannot be decomposed into conflict, unrest, currency and comparison effects.
6. Why the U.S. slowed again: U.S. room nights went from low teens in Q1 to high single digits in Q2 to mid-single digits in Q3. The prepared remarks stressed three years of outperforming the market and did not explain the trend.
7. Why the buyback slowed: Repurchases fell to $2.1 billion from $3.7 billion in a quarter when the shares fell sharply, with $12.4 billion of authorization remaining. No reason was given.
8. KAYAK, four quarters after the impairment: Still no update, in a year when the 10-Q says SEO traffic will keep declining. No analyst has asked in five calls.
9. Rental cars: A third consecutive decline, attributed in the 10-Q to "lower partner volume." It was not discussed on the call, and that phrase suggests a supplier relationship has changed.

Market Reaction

• Pre-print setup: BKNG closed at $155.67 on November 3 ahead of the after-market release, down 27.3% year to date against a 10.6% gain for the S&P 500, down 22.6% over the trailing twelve months and down 2.1% over the trailing 30 days. The pre-print 52-week closing range was $147.94 to $219.68, and the low was set on October 28. The stock had fallen 24.8% since our August 5 note at $207.02.
• After-hours move: Shares traded roughly 1% to 2% lower after hours as the Q4 guide and the FTC charge registered first.
• Reaction session: The stock opened at $160.39, a 3.0% gap up, traded between $160.00 and $174.09, and closed at $170.97, up 9.8% or $15.30. The close was in the upper quarter of the day's range.
• Volume: 14.6 million shares against a 7.6 million 30-day average, or 1.9 times normal.
• Benchmark and peer: The S&P 500 rose 1.6% and Expedia rose 10.5% in the same session.

Braced for Worse

The overnight dip and the next-day rally read the same disclosure in opposite ways. The after-hours trade priced the headline items: a flat Q4 guide and a $1 billion charge. The regular session priced the rest: B2C marketing leverage, LLM referrals still below 1% with most of the traffic arriving at Booking, Agoda and OpenTable inside Meta's Muse, and a healthy first-half 2027 order book. For a stock that had lost a quarter of its value in three months, largely on agent fear, that was enough.

A Sector Move as Much as a Stock Move

Some of the move was not about Booking. Expedia rose 10.5% in the same session and the S&P 500 rose 1.6%. The online travel group had sold off together in September and October on the agent question, and it re-rated together once the largest company in the group described the agent channel as additive. The rally recovered less than half the decline since August. Even at $170.97 the stock is 17.4% below where we downgraded it.

What the Price Now Discounts

At $170.97 the market pays 14.6x our FY2027 estimate. In August it paid 17.0x on a higher estimate. The multiple has compressed while constant-currency revenue growth went from 7% to 10%. The market is now pricing a structural risk to the take rate from agents. That risk is real, but it has not yet appeared in a single reported number.

Street Perspective

Debate: Is the Q4 guide an air pocket or the start of a slowdown?

Bull view: The optimists argue that the guide stacks four separate headwinds on one quarter: a two-point currency drag, the toughest comparison of the year, October's Middle East and European disruptions, and a deliberate investment step-up. The full-year guide was held, Q3 cleared every high end, and the first-half 2027 order book is healthy. On this view Q4 is a trough, not a trend.

Bear view: The skeptics note that demand "moderated" before October's events, that U.S. growth has slowed for two quarters running, and that the Middle East assumption has now been extended twice. A company that guides 1% to 3% room nights in a quarter when it said international travel was recovering may be seeing a broader consumer slowdown.

Our take: Mostly air pocket. The late-Q3 moderation is the one bear point we cannot dismiss. Currency explains about half of the gross-bookings gap to the Street but none of the room-night gap, and the room-night print is the number to watch. We would change our view on a Q4 room-night print below 1% or a 2027 framework below 8% in constant currency.

Debate: Does the agent era make Booking a supplier or a casualty?

Bull view: The bull case holds that horizontal agents need real-time inventory, payments and customer service across millions of independent properties, and that only aggregators can supply it. Booking already receives the vast majority of LLM referral traffic, is live on Muse through Agoda and OpenTable, and has its own agent products. More fragmented discovery means cheaper customer acquisition.

Bear view: The bear camp contends that the agent that owns the user will own the margin. When the booking is completed inside Muse or a similar assistant, Booking becomes a wholesale supplier, the Genius and app flywheel loses its point of contact, and take rates compress. Expedia's head start inside Muse showed the market how fast that can be priced.

Our take: The supplier argument is stronger today, and the casualty argument is about economics no one has yet disclosed. Every number Booking reports, from direct mix to app mix and referral share, still points to a business holding its customer relationships. We would move toward the bear view on the first evidence of agent-completed bookings at a lower take rate, or of B2C marketing deleverage returning.

Debate: Is the FTC charge a one-off or a business-model problem?

Bull view: The optimists see a single brand, a single affiliate relationship and a resolvable consumer-protection case, sized and accrued before settlement. The cash is about 11% of one year's free cash flow, and the adjusted numbers properly exclude it.

Bear view: The skeptics point out that the charge reduced revenue, that the FTC may seek more, that claims in other jurisdictions are possible, and that the EU opened a separate Digital Services Act investigation into Booking.com in October. Fee and disclosure practices are core to how online travel monetises, and a settlement that changes them at Priceline sets a template for the rest of the group.

Our take: The cost is one-off and the risk is not. We accept the exclusion from adjusted earnings but treat regulatory exposure as a standing bear point from this quarter, and it is the reason we trim the fair-value multiple by one turn.

Debate: Is 14x to 15x next year's earnings the floor?

Bull view: The bull case holds that a business with 47% third-quarter EBITDA margins, 10% constant-currency growth, a share count falling 7.5% a year and 4.7 million properties on Booking.com alone should not trade near the low end of its historical range. Most of the Street kept positive ratings while cutting targets.

Bear view: The bears argue that the multiple should fall when the terminal value is in question, that EPS growth is now half buyback, and that the investment step-up may keep 2027 EBITDA growth below revenue growth.

Our take: The bulls have the better case at this price. A business compounding operating earnings at high single digits and shrinking its share count by more than 5% a year earns a mid-teens multiple even with an agent discount. At 14.6x FY2027E, the price assumes more damage than the reported numbers show.

Model Update & Valuation Framework

Valuation. At the November 4 close of $170.97, BKNG trades at about 18.7 times FY2025 adjusted EPS of $9.12, 16.4 times our FY2026 estimate of about $10.40, and 14.6 times our FY2027 estimate of about $11.75. In August, at $207.02, it traded at 20.1 times FY2026 and 17.0 times FY2027. The FY2026 multiple has compressed by about 18% while the operating evidence improved.

Fair value framework. We continue to anchor on FY2027, since 2026 carries a conflict-depressed fourth quarter and an investment step-up. Applying 16 to 18 times our FY2027 estimate of about $11.75 gives a fair value range of about $188 to $212, with a midpoint near $200. Against $170.97 that implies about 10% to 24% upside, with a midpoint of about 17%. Holding the August range of 17 to 19 times would have put the midpoint near $211. The $207.02 price we called full in August now sits inside the new range, at about 17.6 times $11.75 and about 2% below the $212 top.

Why the multiple range came down one turn. Two things are new and negative: a regulatory bear point that did not exist in our framework in August, and a sharper version of the agent risk, booking inside the assistant rather than referral from it. Against them, constant-currency growth returned to 10% and every Connected Trip vertical re-accelerated. We net them by trimming the range one turn rather than two, and the upgrade holds on the trimmed range.

Our August triggers, graded. In August we wrote: "Returning to Outperform requires either a pullback toward the high teens times FY2027, or evidence that constant-currency revenue growth is back above 8% with the Connected Trip verticals re-accelerating." Both fired. The stock trades at 14.1 times the August FY2027 estimate of $12.15, and constant-currency revenue grew about 10% with every vertical re-accelerating. We also wrote: "We would move to Underperform only on evidence that the LLM referral share has begun to inflect, that the direct channel is shrinking in absolute terms, or that the accommodation core has joined the verticals in decelerating." The first of these fired as written. Referrals "accelerated over the last several weeks," where in August management said the share "hasn't moved so much recently." The second did not fire, because direct room nights grew in line with the rest of the business. The third did not fire on Q3 actuals, with room nights accelerating to 6.7% from 5.3%, but the Q4 guide of 1% to 3% puts it on course, and it stays live as written.

How the fired triggers net. We did not say in August how an upgrade trigger and a downgrade trigger would net if both fired, so we state the netting here rather than in advance. The word "only" made the referral trigger a necessary condition for a downgrade, not a sufficient one, and both upgrade triggers fired in the same quarter. The upgrade holds for four reasons. The referrals send users to Booking rather than keep them inside the model, the share is still significantly below 1%, B2C marketing levered in the same quarter, and there is no evidence yet of agent-completed bookings at a lower take rate. The fired trigger moves Bear #1 back to EMERGING. It does not outweigh a 17% fall in price against better operations.

What would change the rating. We would return to Hold if the stock reaches the top of our range, about $212, without an estimate increase, or if the FTC resolution materially exceeds the $1.0 billion accrual or extends to Booking.com. The August direct-channel and accommodation-core Underperform triggers stay live as written. We add three Underperform triggers, which do not replace the August ones: evidence that agents are completing bookings at a lower take rate, that B2C marketing deleverage has returned, or that Q4 room nights fall below the 1% low end and the February framework sits below 8% in constant currency.

Thesis Scorecard Post-Earnings

Scored against the six pillars established at initiation and carried through four quarters, plus one regulatory bear point added this quarter.

Overall: The operating thesis strengthened and the risk list grew. All three bull pillars are now on track, with Connected Trip restored a quarter after we scored it AT RISK, and constant-currency growth is back above the company's 8% floor. Against that, the AI risk took a sharper form, the earnings line is now half buyback, and a regulatory risk we had not scored has produced a $1 billion charge. The stock has fallen 17% since our Hold, to a multiple that prices the risks and not the operations.

Action: Buy. We downgraded on price in August and upgrade on price now. We would add on a Q4 print that clears its range, and we would reassess on agent-completed bookings at a lower take rate or on an FTC resolution well above the accrual.
