Organization and Business Description | 1. Organization and Business Description CarGurus, Inc. (the “Company”) is a multinational, online automotive platform for buying and selling vehicles that is building upon its industry-leading listings marketplace with digital retail solutions. The CarGurus platform gives consumers the confidence to purchase and/or sell a vehicle either online or in person, and it gives dealerships the power to accurately price, effectively market, instantly acquire, and quickly sell vehicles, all with a nationwide reach. The Company uses proprietary technology, search algorithms, and data analytics to bring trust, transparency, and competitive pricing to the automotive shopping experience. On August 6, 2025, the Board of Directors of the Company determined, after considering all reasonably available options and a broader strategic reassessment, that it is in the best interests of its stockholders to wind down CarOffer, LLC (“CarOffer”), including the Dealer-to-Dealer and Instant Max Cash Offer products (the “CarOffer Transactions Business”). Following the broader strategic reassessment, the Company concluded that the CarOffer Transactions Business has proven less effective in today’s more volatile and unpredictable pricing environment, where dealers require more flexibility and broader automation to streamline fulfillment than the model could provide. Following the wind-down, the Company will continue to deliver AI-powered inventory intelligence through its insights platform and enable consumer vehicle sourcing at scale through Sell My Car - Top Dealer Offers and will focus on technology and analytics that will enable smarter sourcing and pricing decisions rather than facilitating the transactions themselves. Refer to Note 14 of the Unaudited Condensed Consolidated Financial Statements (as defined below) for further information. The Company operates principally in the U.S., where it also operates the Autolist online marketplace and the CarOffer online wholesale platform as independent brands. The Company also operates online marketplaces under the CarGurus brand in Canada and the U.K. In the U.K. it also operates the PistonHeads online marketplace as an independent brand. The Company has subsidiaries in the U.S., Canada, Ireland, and the U.K. and it has two reportable segments, U.S. Marketplace and Digital Wholesale. Refer to Note 13 of the Unaudited Condensed Consolidated Financial Statements for further segment reporting and geographic information. The Company is subject to a number of risks and uncertainties common to companies in its and similar industries and stages of development including but not limited to rapid technological changes, competition from substitute products and services from larger companies, management of international activities, protection of proprietary rights, patent litigation, and dependence on key individuals.
