(1) Nature of Business AdaptHealth Corp. and subsidiaries (AdaptHealth or the Company), f/k/a DFB Healthcare Acquisitions Corp. (DFB), a Delaware corporation, was originally formed in November 2017 as a publicly traded special purpose acquisition company for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar business combination involving one or more businesses. On July 8, 2019, AdaptHealth Holdings LLC (AdaptHealth Holdings) entered into an Agreement and Plan of Merger (the Merger Agreement), as amended on October 15, 2019, with DFB, pursuant to which AdaptHealth Holdings combined with DFB (the Business Combination). The merger was approved by DFBs stockholders, and the Business Combination closed on November 8, 2019. AdaptHealth Holdings was the accounting acquirer in the merger, which was treated as a reverse recapitalization. Accordingly, for accounting purposes, the merger was treated as the equivalent of AdaptHealth Holdings issuing stock for the net assets of DFB, accompanied by a recapitalization. The net assets of DFB were stated at historical costs in the Companys consolidated financial statements, with no goodwill or intangible assets recorded. In connection with the Business Combination, the name of the combined company was changed to AdaptHealth Corp. Pursuant to the Merger Agreement, on the closing date, the Company contributed cash to AdaptHealth Holdings in exchange for AdaptHealth Holdings common unit interests equal to the number of shares of the Companys Class A Common Stock outstanding on the closing date. In connection with the Business Combination, the Company also issued and sold in a private placement an aggregate of 12,500,000 shares of Class A Common Stock for aggregate consideration of $125,000,000. In addition, the Company (1) issued 17,386,201 shares of Class A Common Stock to certain members of AdaptHealth Holdings in exchange for their interests in AdaptHealth Holdings, and (2) issued 32,113,799 shares of Class B Common Stock to certain members of AdaptHealth Holdings who retained their common unit interests in AdaptHealth Holdings.
