CoStar EBITDA doubles in Q3 as bookings miss expectations
CoStar’s third-quarter slides showed EBITDA doubling, but bookings fell short of expectations. The split leaves the next earnings update to clarify whether profitability can offset weaker demand conversion.
STOCK PHOTO · LUKE MILLERThe story
CoStar’s third-quarter presentation showed EBITDA doubling, while bookings disappointed relative to expectations. The figures came from slides highlighted on Oct. 27, framing the quarter as a strong profitability result alongside a weaker bookings outcome.
The contrast is between earnings growth and demand execution: EBITDA improved sharply, but bookings did not meet expectations. No further quarterly figures or management commentary are established here.
CoStar Group’s latest annual company figures provide broader context: FY 2025 revenue was $3.2B, up 18.7% year over year, with a 78.9% gross margin, 0.2% net margin and $0.02 diluted EPS. Those annual figures are separate from the Q3 2026 slide update.
The unresolved point is whether the bookings shortfall is temporary or signals slower conversion into future revenue. The next quarterly results and updated bookings figures should provide the clearest evidence.
Our read · Tue, Oct 27
CoStar (CSGP) doubled EBITDA in Q3 2026 as bookings came in below expectations.
Why. The quarter creates a two-sided setup: sharply higher EBITDA supports the earnings profile, but weaker bookings challenge the durability of future revenue conversion. CoStar’s FY 2025 revenue was $3.2B, up 18.7% year over year, while its 0.2% net margin leaves execution on demand growth important to the broader profit story.
Both cases
What could change this view: A further bookings slowdown or weaker conversion into revenue would undercut the EBITDA improvement; sustained bookings recovery would weaken the concern.
