Business Description

1. Description of Business Definitive Healthcare Corp. (together with its subsidiaries, “Definitive Healthcare” or the “Company”), through its operating subsidiary, Definitive OpCo, provides comprehensive and up-to-date hospital and healthcare-related information and insight across the entire healthcare continuum via a multi-tenant database platform which combines proprietary and public sources to deliver insights. Unless otherwise stated or the context otherwise indicates, references to “we,” “us,” “our,” “Definitive Healthcare,” and the “Company” refer (1) prior to the consummation of the Reorganization Transactions, to Definitive OpCo and its consolidated subsidiaries, and (2) after consummation of the Reorganization Transactions, to Definitive Healthcare Corp. and its consolidated subsidiaries. Organization Definitive Healthcare LLC, a subsidiary of Definitive Healthcare Holdings, LLC (“Definitive Holdco”), was founded in 2011 for the purpose of providing healthcare commercial intelligence that enables all companies that compete within or sell into the healthcare ecosystem to be more successful. AIDH TopCo, LLC (“Definitive OpCo”) is a Delaware limited liability company that was formed by investment funds affiliated with Advent International for the purposes of acquiring Definitive HoldCo. In July 2019, Definitive OpCo acquired a majority of the issued and outstanding units of Definitive HoldCo. In May 2021 , Definitive Healthcare Corp. was formed as a Delaware corporation for the purposes of facilitating an initial public offering ( “IPO”) and other related transactions in order to carry on the business of Definitive OpCo. Following consummation of the Reorganization Transactions, Definitive OpCo became a subsidiary of Definitive Healthcare Corp. The Company is headquartered in Framingham, Massachusetts. Reorganization Transactions In connection with its IPO in September 2021, the Company completed the following transactions (the “Reorganization Transactions”). Definitive OpCo entered into an amended and restated limited liability company agreement (the “Amended LLC Agreement”) pursuant to which members of Definitive OpCo prior to the IPO who continued to hold LLC Units following the consummation of the Reorganization Transactions acquired the right to require Definitive OpCo to redeem all or a portion of their LLC Units for newly issued shares of Class A common stock on a one-for-one basis. Until redeemed or exchanged, each LLC Unit is paired with one share of Definitive Healthcare Corp. Class B common stock. The total shares of Class B common stock outstanding is equal to the number of vested LLC Units outstanding, excluding LLC Units held by the Company. Unvested LLC Units are paired with Class B common stock, which are issued but do not have voting rights and are deemed not outstanding until the corresponding LLC Units have vested. Certain entities treated as corporations for U.S. federal income tax purposes that held LLC Units (individually, a “Blocker Company” and collectively, the “Blocker Companies”) each merged with a merger subsidiary of Definitive Healthcare Corp., and subsequently merged into Definitive Healthcare Corp. (the “Mergers”). The former shareholders of the Blocker Companies collectively received a number of shares of Class A common stock in the Mergers equal to the number of LLC Units held by the Blocker Companies prior to the Mergers. Following the Reorganization Transactions, Definitive Healthcare Corp. became a holding company, with its sole material asset being a controlling equity interest in Definitive OpCo. Definitive Healthcare Corp. operates and controls all of the business and affairs of Definitive OpCo, and through Definitive OpCo and its subsidiaries, conducts its business. Accordingly, Definitive Healthcare Corp. consolidates the financial results of Definitive OpCo, and reports the noncontrolling interests of unexchanged LLC Unit holders on its consolidated financial statements. In connection with the Reorganization Transactions and the IPO, Definitive Healthcare Corp entered into a tax receivable agreement (“TRA”). See Note 20. Income Taxes .
