CoStar Group Gains as Investors Reassess Growth Story Ahead of Earnings

Investivoq PriceTracker

CoStar Group (CSGP) is up 7.7% today. Here is some analysis on what might have caused this price movement.

Analysis: There does not appear to be one clear, same-day company announcement driving the rally. This could be because investors are repositioning ahead of CoStar Group’s October 27, 2026 earnings report while continuing to digest several recent positives, including stronger profitability trends in residential, the completed Zonda acquisition, and leadership moves at Homes.com.

Details:

  • CoStar Group said on October 1 that it will report third-quarter 2026 results after the market closes on October 27, giving investors a near-term catalyst to reassess the business.
  • In its July 28 earnings release filed with the SEC, the company reported second-quarter revenue of $925 million, up 18% year over year, while adjusted EBITDA more than doubled to $184 million and the residential segment turned adjusted EBITDA positive.
  • That same filing also showed a mixed setup: full-year adjusted EBITDA guidance was affirmed, but full-year revenue guidance was revised to $3.715 billion to $3.755 billion, which had previously weighed on sentiment and may now be setting up a rebound from depressed levels.
  • CoStar completed its $800 million acquisition of Zonda on August 21, adding a profitable new-home data and software platform with more than 3,000 customers, and later named Felix Kusch president of Homes.com as it pushes to scale that marketplace.
