Organization, Consolidation and Presentation of Financial Statements	1. Organization and Description of Business 23andMe Holding Co. (the “Company”) is dedicated to helping people access, understand, and benefit from the human genome. The Company pioneered direct-to-consumer genetic testing through its Personal Genome Service® (“PGS”) products and services. Customers receive reports that provide them with information on their genetic health risks, their ancestry, and their traits, based on genetic testing of a saliva sample they send to the Company in an easy-to-use “spit kit” provided by the Company. Customers have the option to participate in the Company’s research programs. The Company analyzes consenting customers’ genotypic and phenotypic data to discover new insights into genetics. The Company uses these insights to generate new PGS reports, and, through its therapeutics business and collaborations with pharmaceutical companies, nonprofit institutions and universities, to discover and advance new therapies for unmet medical needs. The Company acquired Lemonaid Health, Inc. (“Lemonaid” or “Lemonaid Health”) in November 2021 (the “Lemonaid Acquisition”), which offers patients affordable and direct online access to medical care, from consultation through treatment, for a number of common conditions, using evidence-based guidelines and up-to-date clinical protocols to deliver quality patient care. Lemonaid Health’s telehealth platform provides patients with easy access to medical consultation and treatment, which enhances the Company’s ability to bring better healthcare and wellness offerings to patients. 23andMe, Inc., the Company’s accounting predecessor, was incorporated in Delaware in 2006.

On June 16, 2021 (the “Closing Date”), VGAC and Chrome Merger Sub, Inc., a Delaware corporation and wholly owned direct subsidiary of VGAC (“Merger Sub”), consummated a merger with 23andMe, Inc. (the “Merger”), whereby Merger Sub merged with and into 23andMe, Inc., with 23andMe, Inc. being the surviving corporation and a wholly owned subsidiary of the Company. In connection with the Merger, VGAC changed its jurisdiction of incorporation from the Cayman Islands to the State of Delaware and changed its name to 23andMe Holding Co. (the “Domestication” and, together with the Merger, the “Business Combination”). The Company has evaluated how it is organized and managed and has identified two reporting segments: Consumer and Research Services, and Therapeutics.
