This prospectus supplement supplements the prospectus dated March 23, 2020 (the “Prospectus”), which forms a part of our registration statement on Form S-1 (No. 333-236011). This prospectus supplement is being filed to update and supplement certain information in the table in the section entitled “Selling Securityholders” in the Prospectus to reflect the exchange (the “Exchange”) on June 24, 2020 by Deerfield Private Design Fund IV, L.P. of 15,810,547 shares of Class A Common Stock for 158,105.47 shares of a new series of preferred stock of the Company designated as “Series B-1 Convertible Preferred Stock,” par value $0.0001 per share (“Series B-1 Preferred Stock”), which is convertible into 15,810,547 shares of Class A Common Stock.

The Prospectus and this prospectus supplement relate to (i) the issuance by us of up to 9,601,909 shares of our Class A Common Stock, par value $0.0001 per share (“Class A Common Stock”), which consists of (A) 5,268,576 shares issuable upon the exercise of warrants that were issued in our initial public offering pursuant to the registration statement declared effective on February 15, 2018 (the “public warrants”) and (B) 4,333,333 shares issuable upon the exercise of warrants initially issued to Deerfield/RAB Ventures LLC (our “Sponsor”) in a private placement that occurred simultaneously with our initial public offering (the “private placement warrants” and collectively with the public warrants, the “warrants”), which private placement warrants have been distributed from the Sponsor to its members, and (ii) the offer and sale from time to time in one or more offerings by the selling securityholders identified in the Prospectus of up to 75,053,512 shares of our Class A Common Stock and up to 4,333,333 private placement warrants.

Our Class A Common Stock is listed on the Nasdaq Capital Market (“Nasdaq”) and trades under the symbol “AHCO”. On June 26, 2020, the closing price of our Class A Common Stock was $16.85. Our public warrants were formerly listed on Nasdaq under the symbol “AHCOW” and were suspended from trading on Nasdaq on December 6, 2019 because the public warrants did not satisfy the minimum 300 round lot holder requirement for listing, at which time the warrants became eligible to trade “over-the-counter” under the trading symbol “AHCOW”. A Form 25-NSE with respect to the public warrants was filed by Nasdaq on January 21, 2020, and the formal delisting of the public warrants became effective ten days thereafter. The private placement warrants are not listed on any exchange.

This prospectus supplement should be read in conjunction with the Prospectus, which is to be delivered with this prospectus supplement. This prospectus supplement is qualified by reference to the Prospectus, except to the extent that the information in this prospectus supplement updates and supersedes the information contained in the Prospectus.
