Item 3. Source and Amount of Funds or Other Consideration

Pursuant to a letter agreement, dated as of February 14, 2020 (the “Founder Shares Transfer Letter”), Boxwood Sponsor, LLC transferred to GSO COF III, for no consideration, 1,200,000 shares of Class F common stock of the Issuer (“Founder Shares”), which converted automatically into 1,200,000 shares of Class A Common Stock pursuant to the terms and conditions of the Issuer’s amended and restated certificate of incorporation at the time of the closing of the acquisition of all of the outstanding equity interests of Atlas Intermediate Holdings LLC by Atlas TC Buyer LLC, an indirect wholly-owned subsidiary of the Issuer, from Atlas Technical Consultants Holdings LP, which closing occurred on February 14, 2020 (the “Business Combination”).

Such transfer of Founder Shares constituted payment-in-kind of a portion of a fee owing to the Reporting Persons pursuant to a payment letter, dated as of January 23, 2020 (“Payment Letter”), from GSO Capital Partners LP, on behalf of its affiliates and funds and accounts managed or advised by it (“GSO”), addressed to the Issuer and its wholly-owned subsidiary, Atlas TC Holdings LLC, a Delaware limited liability company (“Holdings”), in exchange for GSO’s commitment to fund a portion of the amounts needed to consummate the Business Combination and the costs and expenses incurred in connection therewith, which commitment is set forth in a commitment letter, dated as of January 23, 2020, by and among GSO, the Issuer and Holdings (the “Commitment Letter”).

Pursuant to the Commitment Letter, GSO committed, on the terms and subject to the conditions set forth therein, on the closing date of the Business Combination, to purchase (i) up to 145,000 units of a new class of Series A Senior Preferred Units of Holdings (the “Preferred Units”) at a price per Preferred Unit of $980, reflecting a 2% original issue discount to the amount of the liquidation preference of $1,000 per Preferred Unit (“OID”) in accordance with the terms of the Payment Letter (the “Preferred Commitment”), and (ii) 1,000,000 shares of Class A Common Stock (the “Common Commitment”).

Pursuant to a subscription agreement, dated as of February 14, 2020 (“Subscription Agreement”), between GSO COF III AIV-2 LP, an affiliate of GSO (“GSO COF III AIV-2”), and Holdings, GSO COF III AIV-2 acquired 145,000 Preferred Units for an aggregate purchase price of $141.84 million reflecting a 2.179% OID in satisfaction of the Preferred Commitment. Simultaneously therewith, GSO COF III AIV-2 was admitted as a member of Holdings and became bound by the Amended and Restated Operating Agreement of Holdings, dated as of February 14, 2020 (the “Holdings LLC Agreement”). The acquisition of the Preferred Units was funded by capital contributions of the limited partners and general partner of GSO COF III AIV-2.

The Reporting Persons acquired 1,000,000 shares of Class A Common Stock for $10.26 per share for an aggregate purchase price of $10.26 million, in satisfaction of the Common Commitment (the “Stock Purchase”). The acquisition of such shares of Class A Common Stock was funded by capital contributions of the limited partners and general partner of GSO COF III.

The foregoing descriptions of the Founder Shares Transfer Letter, the Payment Letter, the Commitment Letter and the Subscription Agreement do not purport to be complete and are qualified in their entirety by reference to such agreements which are each filed herewith as Exhibits B, C, D and E, respectively, to this Statement and incorporated by reference herein.

Item 4. Purpose of Transaction.

The Reporting Persons acquired the securities reported herein for investment purposes, subject to the following:

The information in Items 3 and 6 of this Schedule 13D is incorporated herein by reference.

The Reporting Persons, through GSO COF III AIV-2’s ownership of Preferred Units, have negative control rights over certain aspects of the business and affairs of Holdings and its subsidiaries. Under the Holdings LLC Agreement, the prior written consent of GSO COF III AIV-2, as the holder of Preferred Units constituting at least a majority of the outstanding Preferred Units in the aggregate, is required before Holdings or its subsidiaries are permitted to, among other things, incur additional indebtedness in excess of a specified leverage ratio, dispose of assets, transact with affiliates, make certain dividend payments, or make changes to Holdings’ organizational documents in a manner adverse to the Reporting Persons, in each case, subject to the exceptions and limitations described therein. The foregoing description of the Holdings LLC Agreement does not purport to be complete and is qualified in its entirety by reference to such agreement, which is filed herewith as Exhibit F and is incorporated by reference in its entirety.

The Reporting Persons intend to review their investment in the Issuer on an ongoing basis and, in the course of their review, may take actions (including through their affiliates) with respect to their investment or the Issuer, including communicating with the board of directors of the Issuer (the “Board”), members of management or other security-holders of the Issuer, or other third parties from time to time, taking steps to implement a course of action, including, without limitation, engaging advisors, including legal, financial, regulatory, technical and/or industry advisors, to assist in any review, and evaluating strategic alternatives as they may become available. Such discussions and other actions may relate to, subject to the terms and conditions of the documents described herein to which the Reporting Persons are a party, various alternative courses of action, including, without limitation, those related to an extraordinary corporate transaction (including, but not limited to a merger, reorganization or liquidation) involving the Issuer or any of its subsidiaries; business combinations involving the Issuer or any of its subsidiaries, a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; material asset purchases; the formation of joint ventures with the Issuer or any of its subsidiaries or the entry into other material projects; changes in the present business, operations, strategy, future plans or prospects of the Issuer, financial or governance matters; changes to the Board (including board composition) or management of the Issuer; acting as a participant in debt financings of the Issuer or any of its subsidiaries, changes to the capitalization, ownership structure, dividend policy, business or corporate structure or governance documents of the Issuer; de-listing or de-registration of the Issuer’s securities, or any action similar to those enumerated above.

Such discussions and actions may be preliminary and exploratory in nature, and not rise to the level of a plan or proposal. Subject to the terms and conditions of the documents described herein to which the Reporting Persons are a party, the Reporting Persons or their affiliates may seek to acquire securities of the Issuer, including Class A Common Stock and/or other equity, debt, notes or other financial instruments related to the Issuer or the Class A Common Stock (which may include rights or securities exercisable or convertible into securities of the Issuer), and/or sell or otherwise dispose of some or all of such Issuer securities or financial instruments (which may include distributing some or all of such securities to such Reporting Person’s respective partners or beneficiaries, as applicable) from time to time, in each case, in open market or private transactions, block sales or otherwise. Any transaction that any of the Reporting Persons or their affiliates may pursue, subject to the terms and conditions of the documents described herein to which the Reporting Persons are a party, may be made at any time and from time to time without prior notice and will depend on a variety of factors, including, without limitation, the price and availability of the Issuer’s securities or other financial instruments, the Reporting Persons’ or such affiliates’ trading and investment strategies, subsequent developments affecting the Issuer, the Issuer’s business and the Issuer’s prospects, other investment and business opportunities available to such Reporting Persons and their affiliates, general industry and economic conditions, the securities markets in general, tax considerations and other factors deemed relevant by such Reporting Persons and such affiliates.

Except as described in this Schedule 13D, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D, although, subject to the agreements described herein, the Reporting Persons, at any time and from time to time, may review, reconsider and change their position and/or change their purpose and/or develop such plans and may seek to influence management or the Board of the Issuer with respect to the business and affairs of the Issuer, and may from time to time consider pursuing or proposing such matters with advisors, the Issuer or other persons.

Item 5. Interest in Securities of the Issuer.

(a) and (b) Calculations of the percentage of common stock beneficially owned assumes 29,740,330 shares of common stock outstanding as of February 14, 2020, of which 5,827,342 shares are Class A common stock and 23,912,988 shares are Class B common stock, as reported in the Issuer’s Current Report on Form 8-K, filed on February 14, 2020.

Each such Reporting Person may be deemed to beneficially own the shares of Class A Common Stock beneficially owned by GSO COF III, but neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that any Reporting Person (other than GSO COF III to the extent it directly holds Issuer securities reported herein) is the beneficial owner of the shares of Class A Common Stock referred to herein for purposes of Section 13(d) of the Exchange Act, or for any other purpose, and each of the Reporting Persons (other than GSO COF III to the extent it directly holds Issuer securities reported herein) expressly disclaims beneficial ownership of such shares of Class A Common Stock.

Any beneficial ownership of shares of Class A Common Stock by any of the persons listed on Schedule I is set forth on Schedule I attached hereto.

(c) Other than as reported in Item 3 of this Schedule 13D, none of the Reporting Persons or, to the best knowledge of the Reporting Persons, any other person named in Schedule I, has effected any transaction in the past 60 days in shares of Class A Common Stock.

(d) To the best knowledge of the Reporting Persons, no person other than the Reporting Persons, or the partners, members, affiliates or shareholders of the Reporting Persons, has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the securities beneficially owned by the Reporting Persons identified in this Item 5.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

The information contained in Items 3, 4 and 5 is incorporated by reference herein, as applicable.

The Founder Shares obtained pursuant to the Founder Shares Transfer Letter are subject to the same lock-up provisions as set forth in the Letter Agreement dated November 15, 2018, among the Issuer, Boxwood Sponsor, LLC and the other signatories thereto (the “Letter Agreement”), namely that GSO COF III may not transfer any

Founder Shares until the earlier of (i) one year after the completion of the Business Combination and (B) subsequent to the Business Combination, (x) if the last reported sale price of the Class A Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Business Combination or (y) the date on which the Issuer completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of the Issuer’s stockholders having the right to exchange their shares of Common Stock for cash, securities or other property.

Pursuant to a Registration Rights Agreement, dated as of February 14, 2020, between the Issuer and GSO COF III, GSO COF III is entitled to (i) make up to two demands of the Issuer to register in an underwritten offering any registrable shares of Class A Common Stock held by GSO COF III, and (ii) customary piggyback registration rights, in each case, subject to certain limitations described therein. The Issuer filed a Registration Statement on Form S-3 (Registration No. 333–236470) on February 14, 2020 and, in accordance with the terms of the Registration Rights Agreement, the shares of Class A Common Stock acquired pursuant to the Stock Purchase were included in such registration statement.
