Expedia Group, Inc.

▲ Bull Case

• ◆B2B platform reaches 46%+ of revenue by FY2027E ($9.1B), driving a re-rating toward software/platform multiples; API-level integrations with banks, airlines, and TMCs are structurally immune to Google AI Mode disruption, and at 50%+ revenue share, EXPE deserves a materially higher blended multiple than the current 10.9x FY2026E adj P/E.
• ◆Google AI Mode disruption plays out over 5–7 years (65% base+bull probability), giving B2B time to compensate for consumer OTA erosion; One Key loyalty program data confirms repeat booking rates +10–15%, validating the customer acquisition cost narrative and preserving consumer OTA economics longer than feared.
• ◆Extraordinary FCF generation ($3.11B FY2025; 11.7% yield) funds aggressive buybacks (~7–8% annual yield) and a growing dividend, compounding per-share value while management executes the B2B pivot; adj EBITDA margins expanding toward 25%+ narrows the gap to Booking Holdings and supports partial multiple re-rating toward the 14x sector fair value floor.

▼ Bear Case

• ◆Google AI Mode accelerates beyond consensus expectations — at 56% of tracked travel queries already routed directly to suppliers, measurable OTA booking declines could materialize within 2–4 quarters, compressing consumer OTA revenue (62% of total) before B2B scale compensates; the 25% bear + 10% severe scenario (35% combined probability) implies a 2yr price of $84–$166.
• ◆Management credibility and execution risk: three CFOs in under two years signals organizational instability at a critical AI adaptation window; if Andersen departs before May 2027, institutional investors are unlikely to underwrite a fourth CFO rotation, and the stock would suffer a multiple de-rating independent of operational results.
• ◆A US macro recession collapses leisure travel demand — Consumer OTA is first-category discretionary spend to contract, operating leverage means adj EBITDA falls faster than revenue, the FCF/buyback narrative stalls, and Diller's governance structure prevents activist intervention or a strategic takeout that could otherwise set a floor.

“The central Wall Street debate is the pace and severity of Google AI Mode disruption to consumer OTA discovery and booking. Bulls argue the 5–7 year disruption timeline gives B2B sufficient runway to reach 50%+ of revenue, transforming EXPE's multiple and justifying accumulation at current prices given the extraordinary FCF yield (11.7%) and 35–40% P/E discount to Booking Holdings. Bears contend the disruption is already measurable (56% of tracked travel queries routed to suppliers), that 62% consumer OTA exposure is too large to hedge near-term, and that governance (Diller control + CFO instability) creates a permanent discount that prevents the re-rating bulls require. A secondary debate concerns whether the current 30% YTD drawdown represents a buying opportunity (guidance conservatism) or a justified derating (structural disintermediation beginning). The resolution depends on Q2–Q3 2026 gross bookings data and independent Google AI Mode traffic research — neither of which is yet conclusive.”

• ◆Q1–Q2 2026 earnings confirm +10–12% gross bookings growth, stabilizing the stock post-30% YTD drawdown and restoring management credibility
• ◆B2B revenue crosses 42% of total revenue milestone, triggering institutional recognition of the platform quality shift and partial multiple re-rating
• ◆One Key loyalty program discloses repeat booking rate improvement of +10–15%, validating lower customer acquisition costs and demonstrating consumer OTA durability
• ◆Adj EBITDA margin reaches 25%+, narrowing the gap to Booking Holdings and supporting upward multiple revision
• ◆Diller succession signal or Class B structure change, removing the governance discount that caps the P/E multiple relative to peers

• ◆Google AI Mode adoption accelerates beyond consensus — independent data showing >15% reduction in consumer OTA-driven bookings for 2 consecutive quarters triggers the primary kill switch (reduce 30%) and raises bear/severe scenario probabilities
• ◆Q2 gross bookings miss below +5% vs. +6–8% guidance — a second consecutive guidance reduction destroys management credibility and removes the 'guidance conservatism' defense following the already-absorbed 30% YTD decline
• ◆B2B revenue growth decelerates to <10% for 2 consecutive quarters, eliminating the core bull thesis that B2B is AI-immune and will reach 50%+ of revenue before consumer OTA erosion becomes material
• ◆Fourth CFO departure within 3 years — disqualifying for institutional investors underwriting the AI adaptation strategy; triggers 15% reduction per kill switch framework
• ◆US macro recession collapses leisure travel demand, compressing consumer OTA revenue (62% of total) with operating leverage amplifying EBITDA impact and stalling the FCF/buyback narrative that underpins intrinsic value
