The announcement was made through an official press release that accompanied the company's disclosure filing. The timing of this announcement aligns with the company's standard quarterly reporting practices, providing shareholders and market participants with updated information regarding operational performance and financial condition during the second quarter of 2026.

The company filed a Current Report on Form 8-K with the Securities and Exchange Commission to formally disclose the announcement of its quarterly results. This filing serves as the official notification to the investing public that the company has released its quarterly financial and operational data. Christian M.

Press Release Contents and Financial Details

The press release issued by CoStar Group on July 28, 2026 constitutes the primary source document containing the company's second quarter results and supporting commentary. The full text of this press release was furnished as an exhibit to the company's Current Report filing with the SEC. Investors seeking specific financial figures, including revenue, earnings per share, operating margins, or other quantitative metrics should consult the press release directly, as these detailed figures are contained within that supplementary disclosure document.

The designation of the press release as "furnished" rather than "filed" with the SEC means that while the document is officially submitted to the Commission as part of the company's disclosure obligations, it is not subject to the same legal liabilities that apply to statements deemed "filed" under securities laws. This distinction reflects standard SEC practices regarding the treatment of earnings announcements and press releases accompanying quarterly results disclosures. Investors should note that the press release contains the operational and financial details that accompany the company's earnings announcement.

Quarterly Reporting Framework and Disclosure Obligations

CoStar Group's announcement and filing follow the established framework of quarterly reporting requirements for publicly traded companies on the NASDAQ exchange. Companies trading on NASDAQ are required to disclose material information regarding their financial condition and operating results on a periodic basis, typically through quarterly filings and earnings announcements. The July 28, 2026 announcement represents CoStar Group's formal notification to the market of its second quarter performance and financial status.

The Current Report filing that accompanies earnings announcements serves as the official vehicle through which companies notify the SEC and investing public of material developments. CoStar Group's filing was completed in compliance with Section 13 or 15(d) of the Securities Exchange Act of 1934, which establishes the legal framework for periodic disclosures by publicly traded companies. The filing was made on July 28, 2026, the same date as the earnings announcement, maintaining consistency with standard disclosure practices in the investment community.

Exhibit and Documentation Structure

The Current Report filing includes two primary exhibits as part of its official submission to the SEC. Exhibit 99.1 consists of the CoStar Group, Inc. press release dated July 28, 2026, which furnishes the detailed announcement of the company's second quarter results. This press release represents the substantive disclosure document that communicates the company's financial and operational information to shareholders and the broader investment community. The exhibit structure ensures that all material information disclosed through the earnings announcement is officially registered with the SEC as part of the company's periodic disclosure obligations.

Exhibit 104 contains the Cover Page Interactive Data File, formatted as inline XBRL (eXtensible Business Reporting Language).

Legal Treatment and Incorporation Framework

CoStar Group's disclosure of its second quarter results through the Current Report mechanism establishes that the information is "furnished" to the SEC rather than "filed." This distinction carries specific legal implications under the Securities Exchange Act of 1934. Information that is furnished rather than filed is not deemed subject to the liabilities set forth in Section 18 of the Securities Exchange Act, nor is it considered incorporated by reference into any other reports or regulatory filings unless expressly referenced in a subsequent document. This treatment is standard for earnings announcements and accompanying press releases provided by public companies.

The furnishing of the press release means that while the document is officially submitted to the SEC as part of the company's disclosure obligations, investors should understand that different legal standards may apply compared to statements that are directly filed. CoStar Group explicitly notes in its Current Report that the information contained in the disclosure shall not be deemed incorporated by reference into future filings unless specifically identified and referenced. This legal framework protects the company while ensuring that material information regarding quarterly results reaches the investing public through official SEC channels.

This document provides the specific figures and commentary necessary for investors to understand the company's quarterly performance and financial condition during the period ended June 30, 2026.

The press release, as submitted to the SEC, remains publicly accessible through the SEC's EDGAR database (Electronic Data Gathering, Electronic Retrieval system) and through CoStar Group's investor relations channels. Investors may also access the full filing through major financial data providers and brokerage platforms. The availability of these resources ensures that shareholders and prospective investors can review the complete disclosure package accompanying the company's earnings announcement. Those seeking detailed financial metrics, forward-looking guidance, or management commentary should refer directly to the press release rather than relying solely on summary information.
