Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Description of Business Ouster, Inc. (“Ouster” or the “Company”) was incorporated in the Cayman Islands on June 4, 2020 as “Colonnade Acquisition Corp.” Following the closing of a business combination between the Company and Ouster Technologies, Inc. (formerly, Ouster, Inc.) in March 2021, the Company domesticated as a Delaware corporation and changed its name to “Ouster, Inc.” Ouster is a leader in sensing and perception for Physical Artificial Intelligence (Physical AI). Ouster’s product offerings enable machines to “Sense, Think, Act, and Learn” and independently execute tasks without human intervention. Physical AI allows machines to move beyond fixed, preprogrammed behavior into adaptive, intelligent action by focusing on perception, understanding, and learning from the physical world. Ouster offers a unified sensing and perception platform that combines high-performance digital lidar, cameras, AI compute, sensor fusion and perception software, and cutting-edge AI models to our customers. On February 4, 2026 (“Closing Date”), the Company completed the acquisition of Stereolabs SAS (“Stereolabs”), accounted for as a business combination. See Note 3. Basis of Presentation and Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries (all of which are wholly owned) and have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) applicable to interim periods. All intercompany balances and transactions have been eliminated in consolidation. The presentation of certain prior period amounts has been reclassified to conform with current period presentation. The unaudited condensed consolidated financial statements include all adjustments (consisting of only normal recurring adjustments) necessary for a fair statement of the results of operations for the periods shown. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of and for the year ended December 31, 2025 and the notes related thereto, included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 2, 2026. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. Certain information and note disclosures normally included in the audited financial statements prepared in accordance with U.S. GAAP have been condensed or omitted from this report, as is permitted by applicable rules and regulations. The results of operations for any interim period are not necessarily indicative of the results to be expected for the year ending December 31, 2026 or for any other future years or interim periods. Liquidity The Company’s principal sources of liquidity are its cash and cash equivalents, short-term investments, cash generated from sales of the Company’s products, sales of common stock under its at-the-market equity offering program and debt financing. The accompanying unaudited condensed consolidated financial statements have been prepared on a going concern basis. The Company has experienced recurring losses from operations, and negative cash flows from operations. As of March 31, 2026, the Company’s existing sources of liquidity included cash, cash equivalents, restricted cash and short-term investments of $174.9 million. The Company has incurred losses and negative cash flows from operations since inception. If the Company continues to incur losses in the future, it may need to improve liquidity and raise additional capital through the issuance of equity and/or debt. There can be no assurance that the Company would be able to raise such capital. However, management believes that the Company’s existing sources of liquidity are adequate to fund its operations for at least twelve months from the date the unaudited condensed consolidated financial statements were available for issuance.
