COSTAR GROUP, INC. 8-K

What Happened
CoStar Group, Inc. (CSGP) announced on May 29, 2026 (filed via Form 8-K) that its wholly owned subsidiary, CoStar Realty Information, Inc., entered into a Stock Purchase Agreement on May 28, 2026 to acquire Zonda (Bora, Inc. and subsidiaries) for $800 million in cash at closing. The transaction is subject to customary closing conditions, including expiration or termination of applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act and other foreign regulatory approvals.

Key Details

• Purchase price: $800 million in cash at closing.
• Parties/dates: Purchase Agreement dated May 28, 2026 among CoStar Realty Information, Inc., Bora Holdings Group, L.P., and Bora, Inc.; 8-K filed May 29, 2026.
• Closing conditions: regulatory clearances (HSR and certain foreign laws), accuracy of each party’s reps and warranties, compliance with covenants, and absence of a material adverse effect related to Zonda.
• Other terms: Transaction does not require CoStar stockholder approval and has no financing condition; either party may terminate if not consummated by May 28, 2027 (subject to certain extensions). The Purchase Agreement and a company press release are attached as exhibits.

Why It Matters
This acquisition expands CoStar’s offerings into new-home construction data, homebuilder software, and residential real estate marketplace solutions through Zonda, a leading provider in that space. For investors, the deal could broaden CoStar’s product set and addressable market, but it remains subject to regulatory approval and customary closing risks (including a material adverse effect clause). The absence of a financing condition and no required shareholder vote may speed completion once approvals are obtained.
