CoStar Group Lifts 2026 EBITDA Guidance Amid Sustained Revenue Growth

CoStar Group (CSGP) has reported a strong start to 2026, highlighted by a significant upward revision of its full-year financial outlook. The company announced it has raised its adjusted EBITDA guidance for 2026 to a range of $780 million to $820 million, signaling confidence in its operational trajectory. This guidance update follows a period of exceptional performance, with the firm marking its 60th consecutive quarter of double-digit revenue growth. Management noted that adjusted EBITDA doubled during the first quarter, positioning the company for what is expected to be its highest full-year adjusted EBITDA to date.
