Marriott Q3 2026: RevPAR surges 6.5%, but co-brand fee confirmation still missing

What happened

Marriott reported Q3 2026 results showing strong RevPAR growth of 6.5% worldwide, with U.S. & Canada up 7.4% and international up 4.4%, marking a significant acceleration from earlier 2026 expectations. Adjusted diluted EPS of $3.02 and adjusted EBITDA of $1,512 million reflect solid fee-driven profitability, while net rooms grew 4.6% year over year to reach a record development pipeline of over 634,000 rooms, 44% under construction. The company repurchased 3.5 million shares for $1.3 billion in the quarter, bringing year-to-date shareholder returns to $4.0 billion, underscoring management's confidence in cash generation. However, the press release omits any detail on co-branded credit card fee growth, which was a key swing factor in the prior investment thesis, and the strong RevPAR may reflect one-time demand or pricing gains that are not guaranteed to persist. While net room additions and pipeline conversion remain on track, valuation remains demanding at roughly 36 times trailing earnings, and the stock's reaction to these results will depend on whether investors believe the RevPAR strength is sustainable and whether co-brand fees are accelerating as planned.

Implication

If subsequent quarters confirm co-brand fee acceleration and RevPAR strength persists, the bear case recedes and fair value moves toward $390; however, until then, the WAIT rating remains appropriate given high valuation and unresolved estimate risks.

Thesis delta

The evidence shifts the probability weight toward the bull/base scenarios by addressing the earlier concern about weak RevPAR, but the core uncertainty around co-brand fee recognition and accounting estimates remains. Net rooms growth is in line but not ahead of plan, and the strong RevPAR may be cyclical rather than structural, so the thesis is only partially confirmed. The rating stays WAIT, but the reassessment window may shorten if co-brand data is disclosed in the next earnings call.
