Michael Burdiek FirstName LastNameMichael Burdiek Motion Acquisition Corp. Comapany August 31, NameMotion 2021 Acquisition Corp. August Page 2 31, 2021 Page 2 FirstName LastName Proposal No. 1 - The Business Combination Proposal Motion's Board of Directors' Reasons for Approval of the Business Combination, page 114 2. We note your revised disclosure in response to prior comment 19 and reissue it in part. We note your disclosure on page 110 that Motion's management had several calls with Barclays to validate and modify the proposed set of publicly listed comparable companies that was initially provided by DocGo. We also note your disclosure here that in valuing DocGo's business, Motion's Board gave considerable weight to the valuations experienced by comparable publicly traded companies in the telehealth and associated sectors of the healthcare industry. Please revise your disclosure to disclose the set of comparable publicly traded companies initially provided by DocGo and discuss the rationale for modifying such list, including the reasons any companies were excluded or additional companies included in the modified list. Background of the Proposed Transaction Certain Forecasted Financial Information for DocGo, page 117 3. The revised disclosure provided in response to prior comment 20 addresses changes that have occurred since the forecasts were developed for the Mobile Health segment. Revise this disclosure to also address any changes that have affected the Transportation Services segment. 4. Disclosure on page 118 states that the revenues from leased hour contracts will be driven by the number of markets in which DocGo operates and how successful DocGo is in obtaining such contracts. Clarify the assumptions that were used to derive the projections for revenues from leased hour contracts. U.S. Federal Income Tax Considerations, page 145 5. We note your response to prior comment 38 and reissue the comment in part. Please revise your disclosure to clearly express an opinion on the tax treatment of the merger and the related transactions. If the merger is not taxable to shareholders, please also file a tax opinion with your registration statement. If there is uncertainty regarding the tax treatment, counsel may issue a "should" or "more likely than not" opinion to make clear that the opinion is subject to a degree of uncertainty, and explain why it cannot give a firm opinion. In that regard, we note that Section 1.14 of the merger agreement provides that the parties intend that the merger qualifies as a "reorganization" within the meaning of Section 368(a) of the Code and your revised disclosure on page 147 that the parties have agreed to report the merger in a manner consistent with such tax treatment so that the merger may qualify as a "reorganization" within the meaning of Section 368 of the Code. Refer to Item 601(b)(8) of Regulation S-K. Michael Burdiek Motion Acquisition Corp. August 31, 2021 Page 3 DocGo's Management's Discussion and Analysis of Financial Condition and Results of Operations Critical Accounting Policies and Significant Judgments and Estimates Stock-Based Compensation, page 204 6. Based on the revised disclosure in response to prior comment 36, it is not clear what supporting factors you believe are relevant in explaining differences between the values of recently granted stock-based awards compared to the fair value implied by the proposed business combination. Provide us with a more comprehensive explanation of the factors you believe support these differences. In addition, provide us with information necessary to compare the weighted average grant date fair value per share for stock options granted during the periods ended June 30, 2021 and December 31, 2020 to their equivalent fair value as implied by the proposed business combination. 7. It does not appear that the expanded disclosure in response to prior comment 37 adequately describes the nature of the material assumptions used to calculate the fair value of DocGo s stock-based awards. Please revise to provide this type of information. Audited Financial Statements of Ambulnz, Inc. and Subsidiaries Notes to Condensed Consolidated Financial Statements Note 2. Summary of Significant Accounting Policies Revenue Recognition, page F-77 8. We note the disclosure added in response to prior comment 45 indicating that all transaction prices are fixed and determinable. We also note the accounting policy description retains the disclosure regarding estimated contractual allowances for claims subject to contracts with responsible paying entities. Please revise your disclosure further to provide a clearer explanation of the nature of these contractual allowances based on their typical characterization in DocGo s contracts with its customers.
