Business and Basis of Presentation	Business and Basis of Presentation Description of the Business Compass, Inc. (the “Company”) was incorporated in Delaware on October 4, 2012 under the name Urban Compass, Inc. On January 8, 2021, the board of directors approved a change to the Company’s name from Urban Compass, Inc. to Compass, Inc. On April 6, 2021, the Company completed its initial public offering (“IPO”) and the Company’s Class A common stock began trading on the New York Stock Exchange on April 1, 2021 under the symbol “COMP”. The Company provides an end-to-end platform that empowers its residential real estate agents to deliver exceptional service to seller and buyer clients. The Company’s platform includes an integrated suite of cloud-based software for customer relationship management, marketing, client service and other critical functionality, all custom-built for the real estate industry, which enables the Company’s core brokerage services. The platform also uses proprietary data, analytics, artificial intelligence, and machine learning to deliver high value recommendations and outcomes for Compass agents and their clients. The Company’s agents are independent contractors who affiliate their real estate licenses with the Company, operating their businesses on the Company’s platform and under the Compass brand. The Company generates revenue from clients through its agents by assisting home sellers and buyers in listing, marketing, selling and finding homes as well as through the provision of services adjacent to the transaction, like title and escrow services, which comprise a smaller portion of the Company’s revenue to date. The Company currently generates substantially all of its revenue from commissions paid by clients at the time that a home is transacted. Basis of Presentation The condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company’s condensed consolidated financial statements were prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and include the assets, liabilities, revenues and expenses of all controlled subsidiaries. The condensed consolidated statements of operations include the results of entities acquired from the date of each respective acquisition. Interests held by third parties in consolidated subsidiaries are presented as non-controlling interests, which represents the non-controlling stockholders’ interests in the underlying net assets of the Company’s consolidated subsidiaries. For entities where the Company does not have a controlling interest (financial or operating), the investments in such entities are accounted for using the equity method. The Company applies the equity method of accounting when it has the ability to exercise significant influence over the operating and financial policies of an investee. The Company measures all other investments at fair value with changes in fair value recognized in net income or in the case that an equity investment does not have readily determinable fair values, at cost minus impairment (if any) plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment. The unaudited interim condensed consolidated financial statements and related disclosures have been prepared by management on a basis consistent with the annual consolidated financial statements and, in the opinion of management, include all adjustments necessary for a fair statement of the interim periods presented. The results of the interim periods presented are not necessarily indicative of the results expected for the full year. Certain information and notes normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted under the SEC’s rules and regulations. Accordingly, the unaudited condensed consolidated financial statements and notes included herein should be read in conjunction with the Company’s audited consolidated financial statements and the related notes for the year ended December 31, 2022 included in the 2022 Form 10-K. Liquidity Since inception, the Company has primarily generated negative cash flows from operations and has primarily financed operations from net proceeds from the issuance of convertible preferred stock and common stock. In addition, a number of macroeconomic conditions, including rising inflation and rapidly rising mortgage interest rates, have contributed to a slowdown in the U.S. residential real estate market, which has had an adverse impact on the Company’s business and may continue to adversely impact the Company’s business in the future. During the year ended December 31, 2022 and the six months ended June 30, 2023, the Company enacted various restructuring actions to improve the alignment between the Company’s organizational structure and its long-term business strategy, drive cost efficiencies enabled by the Company’s technology and other competitive advantages and continue to drive toward profitability and positive free cash flow. The Company will continue to assess the impact that changing macroeconomic factors and the slowdown of the U.S. residential real estate market will have on its business and will adjust its operations as necessary. As of June 30, 2023 and December 31, 2022, the Company held cash and cash equivalents of approximately $335.4 million and $361.9 million, respectively. Additionally, the Company has a Revolving Credit Facility, which it can draw upon provided it maintains continued compliance with certain financial and non-financial covenants. In July 2023, the Company repaid the $150.0 million outstanding as of June 30, 2023 under its Revolving Credit Facility. As a result, the Company has in excess of $300.0 million available to be drawn under the Revolving Credit Facility. Further, the Company is in compliance with each of the financial and non-financial covenants. See Note 5 — "Debt" for further details. The Company believes that it will have sufficient liquidity from cash on hand, its Revolving Credit Facility and future operations to sustain its business operations for the next twelve months and beyond.
