We manage our business by product portfolios in two operating segments, with the primary areas of measurement and decision-making being Commercial Real Estate and Residential Real Estate. Segment reporting is based on the management approach, whereby external segment reporting is aligned with the internal reporting used by the CODM, which is the Company’s Chief Executive Officer. The CODM relies on an internal management reporting process that provides operating segment revenue, EBITDA, and Adjusted EBITDA for making decisions and assessing performance as the source of the Company’s reportable segments. Adjusted EBITDA is used by management internally to measure operating and management performance and to evaluate the performance of the business. Operating results by segment include items that are directly attributable to each segment and also include shared expenses such as legal, including settlements and fines, corporate infrastructure and support costs, facilities, and IT expenses from our integrated platform. Shared expenses are primarily allocated based on revenue or headcount. There are no intersegment transactions. Refer to Note 2 and Note 12 of the Notes to the Condensed Consolidated Financial Statements included in Part I of this Report for additional information. See “Non-GAAP Financial Measures” for further information regarding our segment operating results.

However, this measure should be considered in addition to, not as a substitute for or superior to, (loss) income from operations or other measures of financial performance prepared in accordance with GAAP.

For the trailing 12 months ended September 30, 2025 and 2024, our contract renewal rates for existing company-wide CoStar Group subscription-based services for contracts with a term of at least one year were approximately 89% for each year, and, therefore, our cancellation rates for those services during the same periods were approximately 11%. Contract renewal rates are calculated on all subscription-based contracts with a term of at least one year. Our contract renewal rate is a quantitative measurement that is typically closely correlated with our revenue results. As a result, we believe that the rate may be a reliable indicator of short-term and long-term performance absent extraordinary circumstances. Our trailing 12-month contract renewal rate may decline as a result of negative economic conditions, consolidations among our customers, reductions in customer spending or decreases in our customer base. Revenues from our subscription-based contracts with a term of at least one year were approximately 75% and 80% of total revenues for three months ended September 30, 2025 and 2024, respectively. The decrease in the percentage of revenues from our subscription-based contracts with a term of at least one year is primarily due to Domain, which sells listings on its platforms on a transactional basis, as well as the transactional products and services sold by Matterport.

We expect our investment in the sales force will increase our selling and marketing expenses (excluding customer base amortization) for the year ending December 31, 2025 compared to the year ended December 31, 2024. We intend to continue to assess the need for additional investments in our business in order to develop and distribute new services and functionality within our current platform or expand the reach of, or otherwise improve, our current service offerings. Any future product development or expansion of services, combination and coordination of services, or elimination of services or corporate expansion, development, or restructuring efforts could reduce our profitability and increase our capital expenditures. Any new investments, changes to our service offerings, or other unforeseen events could cause us to experience reduced revenues or generate losses and negative cash flow from operations in the future. Any development efforts must comply with our credit facility, which contains restrictive covenants that restrict our operations and use of our cash flow and may prevent us from taking certain actions that we believe could increase our profitability or otherwise enhance our business.

We prepare and publicly release quarterly unaudited financial statements prepared in accordance with GAAP. We also disclose and discuss certain non-GAAP financial measures in our public releases, investor conference calls, and filings with the SEC. The non-GAAP financial measures that we may disclose include EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, and non-GAAP net income per diluted share. EBITDA is our net income (loss) before interest income or expense, net, other expense or income, net, loss on debt extinguishment, income taxes, depreciation, and amortization. We typically disclose EBITDA on a consolidated and an operating segment basis in our earnings releases, investor conference calls, and filings with the SEC. Adjusted EBITDA is different from EBITDA because we further adjust EBITDA for stock-based compensation expense; acquisition- and integration-related costs; restructuring and related costs, including certain advisory fees; and settlements and impairments incurred outside our ordinary course of business. Adjusted EBITDA margin represents adjusted EBITDA divided by revenues for the period. Non-GAAP net income is determined by adjusting our net income (loss) for stock-based compensation expense, acquisition- and integration-related costs, including gains or losses on equity investments acquired in prospective targets and related to deal-contingent financial instruments; restructuring costs, settlement and impairment costs incurred outside our ordinary course of business, and loss on debt extinguishment, as well as amortization of acquired intangible assets and other related costs, and then subtracting an assumed provision for income taxes. Non-GAAP net income per diluted share is a non-GAAP financial measure that represents non-GAAP net income divided by the number of diluted shares outstanding for the period used in the calculation of GAAP net income per diluted share.

Previous wording

We view EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, and non-GAAP net income per diluted share as operating performance measures. We believe that the most directly comparable GAAP financial measure to EBITDA, adjusted EBITDA, and non-GAAP net income is net income (loss). We believe the most directly comparable GAAP financial measure to non-GAAP net income per diluted share and adjusted EBITDA margin are net income (loss) per diluted share and net income (loss) divided by revenues, respectively. In calculating EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, and non-GAAP net income per diluted share, we exclude from net income (loss) the financial items that we believe should be separately identified to provide additional analysis of the financial components of the day-to-day operation of our business. We have outlined below the type and scope of these exclusions and the material limitations on the use of these non-GAAP financial measures as a result of these exclusions. EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, and non-GAAP net income per diluted share are not measurements of financial performance under GAAP and should not be considered as a measure of liquidity, as an alternative to net income (loss), or as an indicator of any other measure of performance derived in accordance with GAAP. Investors and potential investors in our securities should not rely on EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, and non-GAAP net income per diluted share as a substitute for any GAAP financial measure, including net income (loss) and net income (loss) per diluted share. In addition, we urge investors and potential investors in our securities to carefully review the GAAP financial information included as part of our Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q that are filed with the SEC, as well as our quarterly earnings releases, and compare the GAAP financial information with our EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, and non-GAAP net income per diluted share.

Previous wording

EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, and non-GAAP net income per diluted share may be used by management to internally measure our operating and management performance and may be used by investors as supplemental financial measures to evaluate the performance of our business. We believe that these non-GAAP measures, when viewed with our GAAP results and accompanying reconciliations, provide additional information to investors that is useful to understand the factors and trends affecting our business without the impact of certain acquisition-related items. We have spent more than 30 years building our database of commercial real estate information and expanding our markets and services partially through acquisitions of complementary businesses. Due to these acquisitions, our net income (loss) has included significant charges for amortization of acquired intangible assets; depreciation and other amortization; acquisition- and integration-related costs, including gains or losses on equity investments acquired in prospective targets and related to deal-contingent financial instruments; restructuring and related costs, including certain advisory fees; and loss on debt extinguishment. Adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, and non-GAAP net income per diluted share exclude these charges and provide meaningful information about the operating performance of our business, apart from charges for amortization of acquired intangible assets; depreciation and other amortization; acquisition- and integration-related costs; restructuring and related costs, including certain advisory fees; settlement and impairment costs incurred outside our ordinary course of business. We believe the disclosure of non-GAAP measures can help investors meaningfully evaluate and compare our performance from quarter to quarter and from year to year without the impact of these items. We also believe the non-GAAP measures we disclose are measures of our ongoing operating performance because the isolation of non-cash charges, such as amortization and depreciation, and other items, such as interest income or expense, net; other expense or income, net; income taxes; stock-based compensation expenses; acquisition- and integration-related costs; restructuring and related costs, including certain advisory fees; loss on debt extinguishment; and settlement and impairment costs incurred outside our ordinary course of business, provides additional information about our cost structure, and, over time, helps track our operating progress. In addition, investors, securities analysts, and others have regularly relied on EBITDA and may rely on adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, or non-GAAP net income per diluted share to provide a financial measure by which to compare our operating performance against that of other companies in our industry.

These items are discussed above with respect to the calculation of adjusted EBITDA together with the material limitations associated with using non-GAAP financial measures as compared to net income (loss). In addition to these exclusions from net income, we subtract an assumed provision for income taxes to calculate non-GAAP net income. In both 2025 and 2024, we assume a 26.0% tax rate, which approximates our historical long-term statutory corporate tax rate, excluding the impact of discrete items.
