Stockholders' Equity | Stockholders' Equity AdaptHealth, f/k/a DFB Healthcare Acquisitions Corp. ("DFB"), 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 Business Combination closed on November 8, 2019. In connection with the Business Combination, the name of the combined company was changed to AdaptHealth Corp. Following the closing of the Business Combination, AdaptHealth Corp. owned 56% of the combined company with the remaining 44% owned by the former owners of AdaptHealth Holdings in the form of common units representing limited liability company interests in AdaptHealth Holdings from and after the closing of the Business Combination ("New AdaptHealth Units"). The former owners of AdaptHealth Holdings held New AdaptHealth Units and a corresponding number of non-economic Class B Common stock, which enabled the holder to one vote per share, and were exchangeable on a one-to-one basis for shares of Class A Common Stock. Subsequent to the Business Combination, all of the common unit interests of AdaptHealth Holdings and a corresponding number of shares of Class B Common Stock were exchanged for shares of Class A Common Stock, of which the final 13,218,758 of the exchanges occurred on January 1, 2021. As a result, the prior holders of the common unit interests of AdaptHealth Holdings no longer own a direct noncontrolling economic interest in AdaptHealth Holdings. In connection with the January 2021 exchanges, the Company recorded a decrease to the Noncontrolling interest in subsidiaries of $77.9 million in the accompanying consolidated statements of stockholders’ equity. The Company filed its Third Amended and Restated Certificate of Incorporation (the "Certificate of Incorporation") on July 28, 2021. Among other things, the Certificate of Incorporation (x) increased the authorized number of shares of Common Stock from 245,000,000 shares of Common Stock to 300,000,000 shares of Common Stock and (y) (i) deleted provisions no longer applicable following the exchange of all outstanding New AdaptHealth Units and shares of Class B Common Stock for shares of Class A Common Stock and (ii) renamed the Company’s Class A Common Stock to Common Stock. Holders of Common Stock are entitled to one vote for each share. The shares of Preferred Stock (see below) shall be issued with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. Common Stock In January 2021, the Company issued 8,450,000 shares of Class A Common Stock at a price of $33.00 per share pursuant to an underwritten public offering (the 2021 Stock Offering) for gross proceeds of $278.9 million. In connection with the 2021 Stock Offering, the Company received proceeds of $265.0 million, which is net of the underwriting discount. A portion of the proceeds from the 2021 Stock Offering were used to partially finance the cash portion of the purchase price for the acquisition of AeroCare, and to pay related fees and expenses. In connection with the 2021 Stock Offering, the Company paid offering costs, inclusive of the underwriting discount, of $13.8 million. Preferred Stock In June 2020, the Company entered into an exchange agreement ("the Exchange Agreement") with an investor pursuant to which the investor exchanged 15,810,547 shares of the Company’s Class A Common Stock for 158,105.47 shares of Series B-1 Preferred Stock, par value $0.0001 per share. The Series B-1 Preferred Stock liquidation preference is limited to its par value of $0.0001 per share. The Series B-1 Preferred Stock will participate equally and ratably on an as-converted basis with the holders of Common Stock in all cash dividends paid on the Common Stock. The Series B-1 Preferred Stock is non-voting. The holder may convert each share of Series B-1 Preferred Stock into 100 shares of Common Stock (subject to certain anti-dilution adjustments) at its election, except to the extent that following such conversion, the number of shares of Common Stock held by such holder and its affiliates exceed 4.9% of the outstanding Common Stock of the Company. During the year ended December 31, 2021, 39,500 shares of Series B-1 Preferred Stock were converted into 3,950,000 shares of Common Stock. There were no such conversions during the years ended December 31, 2023 and 2022. As discussed in Note 3, Acquisitions , the Company issued 130,474.73 shares of Series C Convertible Preferred Stock in connection with the acquisition of AeroCare. The Series C Convertible Preferred Stock liquidation preference was limited to its par value of $0.0001 per share. The Series C Convertible Preferred Stock participated equally and ratably on an as-converted basis with the holders of Common Stock in all potential cash dividends paid on the Common Stock. The Series C Convertible Preferred Stock was non-voting. On March 3, 2021, the Company’s stockholders approved, for purposes of complying with Nasdaq Listing Rule 5635, the issuance of shares of the Company’s Common Stock, representing equal to or greater than 20% of the outstanding common stock or voting power of the Company issuable upon conversion of the Series C Convertible Preferred Stock issued to the former equity holders of AeroCare, by removal of the conversion restriction that prohibits such conversion of Series C Convertible Preferred Stock. Following the receipt of the approval of the Company’s stockholders, the holders were able to elect to convert, and the Company was able to elect to effect a mandatory conversion of, each share of Series C Convertible Preferred Stock into 100 shares of Common Stock (subject to certain anti-dilution adjustments). The Company elected to effect a mandatory conversion of the Series C Convertible Preferred Stock, and the conversion of 130,474.73 shares of Series C Convertible Preferred Stock to 13,047,473 shares of Common Stock occurred on March 18, 2021. Treasury Stock In May 2022, the Company's board of directors authorized a share repurchase program for up to $200.0 million of the Company's Common Stock, which expired on December 31, 2023 (the "Share Repurchase Program"). The timing and actual number of shares repurchased depended upon market conditions and other factors. Shares of the Company's Common Stock were repurchased from time to time on the open market, through privately negotiated transactions or otherwise. During the years ended December 31, 2023 and 2022, the Company purchased 3,184,200 and 750,835 shares of the Company's Common Stock, respectively, for $29.3 million and $14.0 million, respectively, under the Share Repurchase Program, which is reflected in Treasury Stock in the accompanying consolidated statements of stockholders' equity. Warrants At the closing of the Business Combination, the Company had 12,666,666 warrants outstanding. Each warrant is exercisable into one share of Common Stock at a price of $11.50 per share. The exercise price and number of shares of Common Stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a share dividend, or recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for the issuance of common stock at a price below its exercise price. There were no warrants exercised during the year ended December 31, 2023. During the year ended December 31, 2022, 184,870 warrants were exercised in cashless transactions resulting in the issuance of 87,553 shares of Common Stock. During the year ended December 31, 2021, 224,121 warrants were exercised in a cashless transaction resulting in the issuance of 118,379 shares of Common Stock. As of December 31, 2023, the Company had 3,871,557 warrants outstanding, which have an expiration date of November 20, 2024. The Company classifies its warrants as a liability in its consolidated balance sheets because of certain terms included in the corresponding warrant agreement. The estimated fair value of the warrants is recorded as a liability, with such fair value reclassified to stockholders’ equity upon the exercise of such warrants. Prior to exercise, the change in the estimated fair value of such warrants each period is recognized as a non-cash charge or gain in the Company’s consolidated statements of operations. A reconciliation of the changes in the warrant liability during the years ended December 31, 2023, 2022 and 2021 was as follows (in thousands): Estimated fair value of warrant liability at December 31, 2020 $ 113,905 Change in estimated fair value of the warrant liability (53,181) Reclassification of warrant liability to equity for exercised warrants (2,960) Estimated fair value of warrant liability at December 31, 2021 57,764 Change in estimated fair value of the warrant liability (17,158) Reclassification of warrant liability to equity for exercised warrants (2,103) Estimated fair value of warrant liability at December 31, 2022 38,503 Change in estimated fair value of the warrant liability (34,482) Estimated fair value of warrant liability at December 31, 2023 $ 4,021 The warrant liability is classified as a current liability at December 31, 2023 in the accompanying consolidated balance sheets since the expiration date of the warrants is less than one year as of such date. Contingent Consideration Common Shares Pursuant to the Merger Agreement, the former owners of AdaptHealth Holdings who received Class A Common Stock and Class B Common Stock in connection with the Business Combination were entitled to receive earn-out consideration to be paid in the form of Common Stock, if the average price of the Company’s Common Stock for the month of December prior to each measurement date equaled or exceeded certain hurdles set forth in the Merger Agreement (Contingent Consideration Common Shares). The former owners of AdaptHealth Holdings were entitled to receive 1,000,000 shares of Common Stock on each of December 31, 2022, 2021, and 2020 based on an average stock price hurdle of $22, $18 and $15, respectively, during the applicable measurement period. The average stock price hurdle was achieved for the applicable measurement periods as of the December 31, 2021 and 2020 measurement dates, which triggered the issuance of 1,000,000 shares of Common Stock on such dates. The average stock price hurdle was not achieved for the applicable measurement period as of the December 31, 2022 measurement date; as such no shares of Common Stock were issued on such date. The Contingent Consideration Common Shares would have been issued immediately in the event of a change of control as defined in the Merger Agreement. The estimated fair value of the Contingent Consideration Common Shares was recorded as a liability in the Company’s consolidated balance sheets, with such fair value reclassified to stockholders’ equity upon the issuance of any shares that were earned. Prior to issuance, the change in the estimated fair value of such shares each period was recognized as a non-cash charge or gain in the Company’s consolidated statements of operations. The Company estimated the fair value of the contingent consideration common shares liability using a Monte-Carlo simulation analysis. A Monte-Carlo simulation is a tool used to project asset prices based on a widely accepted drift calculation, the volatility of the asset, incremental time-steps and a random component known as a Weiner process that introduces the dynamic behavior in the asset price. In this framework, asset prices follow a log-normal distribution as they fluctuate through time, which the simulation process captures. A specific model can be developed around the projected stock price to capture the effects of any market performance conditions on value. Price path specific conditions can be captured in this type of open form model. The Monte-Carlo process expresses potential future scenarios that when simulated thousands of times can be viewed statistically to ascertain fair value. The contingent consideration common shares contain market conditions to determine whether the shares are earned based on the Company’s Common Stock price during specified measurement periods. Given the path-dependent nature of the requirement in which the shares are earned, a Monte-Carlo simulation was used to estimate the fair value of the liability. The Company’s Common Stock price was simulated to each measurement period based on the methodology described above. In each iteration, the simulated stock price was compared to the conditions under which the shares are earned. In iterations where the stock price corresponded to shares being earned, the future value of the earned shares was discounted back to present value. The fair value of the liability was estimated based on the average of all iterations of the simulation. As discussed above, on each of December 31, 2021 and 2020, 1,000,000 shares of Common Stock were issued in connection with the portion of the Contingent Consideration Common Shares which were earned as of such dates. As a result, the estimated fair value related to such shares was reclassified to stockholders’ equity in the periods in which they were earned, with such shares reflected as issued and outstanding Common Stock. In accordance with U.S. GAAP, the estimated fair value related to the remaining 1,000,000 Contingent Consideration Common Shares was reclassified to stockholders’ equity at December 31, 2021. Since the fair value of these shares was reclassified to stockholders’ equity on December 31, 2021, these shares were no longer liability classified as of such date and therefore the changes in the estimated fair value of such shares were not recognized in the Company’s consolidated statements of operations subsequent to December 31, 2021. As of December 31, 2021, the Company recorded a deferred tax asset of $1.6 million in connection with the accounting for the Contingent Consideration Common Shares. As discussed above, the estimated fair value related to the unearned Contingent Consideration Common Shares was reclassified to stockholders’ equity as of December 31, 2021 and was settled without share issuance as of December 31, 2022 . Correspondingly, the Company reversed the $1.6 million deferred tax asset for the Contingent Consideration Common Shares through a reduction to Additional-paid-in capital during the year ended December 31, 2022. A reconciliation of the changes in the contingent consideration common shares liability related to the Contingent Consideration Common Shares during the year ended December 31, 2021 was as follows (in thousands): Estimated fair value of contingent consideration common shares liability at December 31, 2020 $ 70,477 Change in estimated fair value of the contingent consideration common shares liability (29,389) Reclassification of contingent consideration common shares liability to equity (41,088) Estimated fair value of contingent consideration common shares liability at December 31, 2021 $ — Equity-based Compensation In connection with the Company’s 2019 Stock Incentive Plan (the "2019 Plan"), the Company provides equity-based compensation to attract and retain employees while also aligning employees’ interest with the interests of its stockholders. The 2019 Plan permits the grant of various equity-based awards to selected employees and non-employee directors. The 2019 Plan permits the grant of up to 10,000,000 shares of Common Stock, subject to certain adjustments and limitations. At December 31, 2023, 1,039,484 shares of the Company’s Common Stock were available for issuance under the 2019 Plan. Stock Options In January 2021, the Company granted 703,170 options to purchase shares of the Company’s Common Stock to certain senior executives of the Company. The options vest ratably over a three-year period from the date of grant based on a service condition and have a contractual exercise period of five years from the date of grant. The total grant-date fair value of the options granted, using a Black-Scholes option pricing model, was $6.9 million. During the year ended December 31, 2021, 234,390 of the options from this grant were forfeited as a result of the resignation of the Company’s former Co-CEO (see discussion below). In November 2019, the Company granted 3,416,666 options to purchase shares of Common Stock of the Company to certain senior management employees that have an exercise price of $11.50 per share and a contractual exercise period of ten years from the date of grant. The grant-date fair value of the awards, using a Black-Scholes option pricing model, was $7.2 million. In April 2020, the Company granted 47,335 options to purchase shares of Common Stock of the Company to an employee that had an exercise price of $16.25 per share. The grant-date fair value of the awards, using a Black-Scholes option pricing model, was $0.3 million. The vesting conditions relating to the total 3,464,001 options included a defined performance condition with a measurement period during the year ended December 31, 2020 which was satisfied, and also a service condition. In June 2021, in connection with the resignation of the Company’s former Co-CEO (see discussion below), the Company accelerated the vesting of 184,932 options. In connection with the accelerated vesting, the Company recognized $1.9 million of equity-based compensation expense, which is included in general and administrative expenses during the year ended December 31, 2021 in the accompanying consolidated statements of operations. Of the total options granted, 722,222, 722,222 and 1,154,667 options vested on December 31, 2022, 2021 and 2020 respectively. In addition, 679,958 options were forfeited during the year ended December 31, 2021, primarily relating to the resignation of the Company’s former Co-CEO. On April 13, 2021, the Company placed its then Co-Chief Executive Officer, Luke McGee, on unpaid leave while a matter relating to his past private activity was pending. On April 20, 2021, the Company’s board of directors unanimously approved the formation of a Special Committee of Board members to conduct a full investigation of Mr. McGee’s alleged personal conduct. In addition, the Company’s board of directors also approved the retention of an independent law firm to assist the Special Committee in facilitating the investigation. Mr. McGee had no role in, and was entirely recused from, the investigation. On June 11, 2021, the independent law firm reported to the Special Committee that the investigation was substantially complete and that they could state with a high degree of confidence that the Company had no involvement in, or connection to, Mr. McGee’s alleged conduct. The investigation was completed in October 2021 resulting in no changes to the findings communicated in June 2021. On June 14, 2021, the Company and Mr. McGee agreed that Mr. McGee would resign from his positions as Co-CEO and a Director of the Company effective as of June 11, 2021. In connection with Mr. McGee’s resignation, the Company accelerated the vesting of certain unvested stock options as discussed above, and also accelerated the vesting of certain unvested shares of restricted stock (see discussion below). Other than the accelerated vesting of the stock options and shares of restricted stock, and back pay paid to Mr. McGee relating to his unpaid base wages from April 13, 2021 to June 11, 2021, no other compensation was paid to Mr. McGee in connection with his resignation.
