Earnings results
- EPS beat +12.8%
Actual: $0.38 · Cons.: $0.3369 (adjusted diluted EPS)
- Revenue beat +0.7%
Actual: $0.952B · Cons.: $0.94582B (GAAP revenue)
- Guidance
Raised FY2026 adjusted EPS to $1.38–$1.41 from $1.32–$1.39; sales outlook excluding Zonda is $35 million below July.

Earnings and the stock move
CoStar reported third-quarter earnings on October 27, but net new bookings dropped to $37 million from $84 million. Management said its higher headline revenue outlook includes roughly $60 million from Zonda; without that contribution, expected revenue is $35 million below July. Our analysis: weaker future business can outweigh better current profit because subscriptions need a healthy sales pipeline to sustain growth.
Q3 2026 earnings recap
CoStar fell 12.62% to $27.97 during trading on October 28, 2026 after its earnings report revealed weaker new business. Higher current profit did not settle concerns about future growth.
- Net new bookings fell to $37 million from $84 million a year earlier. This tracks changes in subscription contracts after cancellations, making the slowdown a warning for future revenue.
- Quarterly revenue rose 14% to $952 million. Adjusted EPS, or profit per share excluding specified costs, was $0.38; reported GAAP profit per share was $0.18.
- CoStar raised its full-year revenue forecast to $3.75–$3.77 billion, but that includes about $60 million from Zonda. Excluding that addition, management said the outlook is $35 million below July.
- The company still raised its adjusted profit forecast to $1.38–$1.41 per share from $1.32–$1.39. Cost savings support earnings, but stronger sales are needed to make the recovery more durable.
- CoStar earns money from property-data subscriptions and paid marketplace listings, including Apartments.com and Homes.com. Management linked weaker residential bookings to economic pressure and insufficient sales capacity.
- The selloff breaks the recent October recovery. Late-September lows near $26.5–$27.2 are a support area to watch; recovering $29–$30.2 would help repair the chart.
Watch for a rebound in bookings and evidence that added sales capacity improves growth. Property-market weakness, spending needs and another break below support remain risks.
