This Amendment No. 11 amends and supplements the Schedule 13D filed with the Securities and Exchange Commission (the “SEC”) on November 20, 2006, as amended by Amendment No. 1 thereto, filed with the SEC on September 24, 2007, Amendment No. 2 thereto, filed with the SEC on February 7, 2008, Amendment No. 3 thereto, filed with the SEC on December 3, 2008, Amendment No. 4 thereto, filed with the SEC on January 6, 2009, Amendment No. 5 thereto, filed with the SEC on February 3, 2009, Amendment No. 6 thereto, filed with the SEC on May 26, 2009, Amendment No. 7 thereto, filed with the SEC on June 1, 2009, Amendment No. 8 thereto, filed with the SEC on August 29, 2011, Amendment No. 9 thereto, filed with the SEC on June 18, 2012, and Amendment No. 10 thereto, filed with the SEC on August 14, 2012 (together, this “Schedule 13D”), by (i) Red Mountain Capital Partners LLC, a Delaware limited liability company (“RMCP LLC”), (ii) Red Mountain Capital Partners II, L.P., a Delaware limited partnership (“RMCP II”), (iii) Red Mountain Capital Partners III, L.P., a Delaware limited partnership (“RMCP III”), (iv) RMCP GP LLC, a Delaware limited liability company (“RMCP GP”), (v) Red Mountain Capital Management, Inc., a Delaware corporation (“RMCM”), and (vi) Willem Mesdag, a natural person and citizen of the United States of America, with respect to the common stock, par value $0.01 per share (the “Common Stock”), of Air Transport Services Group, Inc., a Delaware corporation (“ATSG”), formerly known as ABX Holdings, Inc. and ABX Air, Inc. Through this Amendment No. 11, Red Mountain Partners, L.P., a Delaware limited partnership (“RMP”), joins as a filer of this Schedule 13D. In addition, this Amendment No. 11 will constitute an exit filing for RMCP II and RMCP III. RMCP LLC, RMCP II, RMCP III, RMP and RMCP GP are sometimes collectively referred to herein as “Red Mountain.” Red Mountain, RMCM and Mr. Mesdag are sometimes collectively referred to herein as the “Reporting Persons.” The filing of any amendment to this Schedule 13D (including the filing of this Amendment No. 11) shall not be construed to be an admission by the Reporting Persons that a material change has occurred in the facts set forth in this Schedule 13D or that such amendment is required under Rule 13d-2 of the Securities Exchange Act of 1934, as amended.

Item 2 of this Schedule 13D is hereby amended to include the following information:

Red Mountain Partners, L.P., a Delaware limited partnership (“RMP”), joins as a filer of this Schedule 13D. RMCP GP is the general partner of RMP and thus may be deemed to control RMP. The principal executive offices of RMP are located at 10100 Santa Monica Boulevard, Suite 925, Los Angeles, California 90067. The principal business of RMP is investment. RMP was not formed for the specific purpose of investing in the securities of ATSG.

During the last five years, RMP has not been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which RMP was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3 of this Schedule 13D is hereby amended to include the following information:

Amendment No. 10 to this Schedule 13D, which was filed with the SEC on August 14, 2012, reported that RMCP II and RMCP III held in the aggregate 10,550,425 shares of Common Stock. Between August 14, 2012 and August 16, 2012, RMCP II acquired an additional 602,000 shares of Common Stock using its own working capital increasing the aggregate Common Stock held by RMCP II and RMCP III to 11,152,425 shares.

Prior to December 31, 2012, RMP was the sole limited partner of each of RMCP II and RMCP III, and RMCP GP was the sole general partner of each of RMP, RMCP II and RMCP III. On December 31, 2012 as part of an internal restructuring, RMCP II and RMCP III distributed all Common Stock held by them to RMP in a transaction that resulted in a change in the form of ownership of such Common Stock by RMP but not in a change in pecuniary interest in such Common Stock by RMP or a change in the control over such Common Stock by RMCP GP and RMCP LLC. As a result of such internal restructuring, RMP became the direct holder of these shares of Common Stock, and RMCP II and RMCP III ceased to beneficially own any Common Stock. Each of RMCP II and RMCP III was subsequently dissolved.

In connection with Mr. Teets’ service on the Board of ATSG since 2009, ATSG has issued Mr. Teets, in the aggregate, 77,929 restricted stock units for a zero purchase price (the “RSUs”) as part of his director compensation, all of which RSUs are fully vested. Mr. Teets has transferred beneficial ownership of all such RSUs to RMCP LLC.

Items 5(a) and 5(b) of this Schedule 13D are hereby amended and restated as follows:

RMP beneficially owns, in the aggregate, 11,152,425 shares of Common Stock, which represent approximately 17.3% of the outstanding Common Stock⁽¹⁾. RMP has the sole power to vote or direct the vote, and the sole power to dispose or direct the disposition, of all such 11,152,425 shares of Common Stock.

Due to its ownership of the RSUs, RMCP LLC may be deemed to beneficially own directly 77,929 shares of Common Stock underlying the RSUs (the “RSU Shares”), representing approximately 0.1% of the outstanding Common Stock (after giving effect to the RSU Shares). RMCP LLC has the sole power to vote or direct the vote, and the sole power to dispose or direct the disposition, of the RSU Shares.

Because each of RMCP GP, RMCP LLC, RMCM and Mr. Mesdag may be deemed to control RMP, each of RMCP GP, RMCP LLC, RMCM and Mr. Mesdag may be deemed to beneficially own, and to have the power to vote or direct the vote, or dispose or direct the disposition of, all of the Common Stock beneficially owned by RMP. As a result, RMCP LLC may be deemed to beneficially own, in the aggregate, 11,230,354 shares of Common Stock, representing 17.4% of the outstanding Common Stock after giving effect to the RSU Shares. In addition, because each of RMCM and Mr. Mesdag may be deemed to control RMCP LLC, RMCM and Mr. Mesdag may be deemed to beneficially own, and to have the power to vote or direct the vote, or dispose or direct the disposition of, all of the RSU Shares beneficially owned by RMCP LLC, as well as all of the shares of Common Stock beneficially owned by RMP. Therefore, each of Mr. Mesdag and RMCM may be deemed to beneficially own, in the aggregate, 11,230,354 shares of Common Stock, representing 17.4% of the outstanding Common Stock after giving effect to the RSU Shares.

Other than shares of Common Stock beneficially owned by RMP and RMCP LLC, none of the Reporting Persons or Mr. Teets may be deemed to beneficially own any shares of Common Stock.

Each of RMCP LLC, RMP and RMCP GP affirms membership in a group with each other but disclaims membership in a group with RMCM or Mr. Mesdag. Each of RMCM and Mr. Mesdag disclaims membership in a group with any person.

The filing of this Schedule 13D shall not be construed as an admission that any Reporting Person is the beneficial owner of any of the shares of Common Stock that such Reporting Person may be deemed to beneficially own. Without limiting the foregoing sentence, each of RMCM and Mr. Mesdag disclaims beneficial ownership of all shares of Common Stock reported in this Schedule 13D. In addition, the filing of this Schedule 13D shall not be construed as an admission that any partner, member, director, officer or affiliate of any Reporting Person is the beneficial owner of any of the shares of Common Stock that such partner, member, director, officer or affiliate may be deemed to beneficially own. Without limiting the foregoing sentence, Mr. Teets disclaims beneficial ownership of all shares of Common Stock reported in this Schedule 13D.

Item 5(e) of this Schedule 13D is hereby amended to include the following information:

Item 6 of this Schedule 13D is hereby amended to include the following information:

On March 8, 2016, RMP entered into a voting agreement with Amazon.com, Inc. (“Amazon”) and ATSG (the “Voting Agreement”), pursuant to which RMP has agreed to vote all of its shares of Common Stock in favor of, among other things, an amendment to ATSG’s certificate of incorporation that would authorize a sufficient number of shares to permit the exercise in full of certain warrants granted to Amazon in connection with commercial agreements whereby ATSG agreed to operate an air cargo network to serve Amazon customers in the United States. The Voting Agreement also contains a restriction on RMP’s ability to sell its shares of Common Stock until immediately following ATSG’s annual meeting of stockholders to be held in the 2016 calendar year.

The Voting Agreement will terminate upon the earliest to occur of several events, but no later than immediately following ATSG’s annual meeting of stockholders to be held in the 2017 calendar year; provided that the restrictions on RMP’s ability to sell its shares of Common Stock shall terminate immediately after ATSG’s annual meeting of stockholders to be held in the 2016 calendar year.

The foregoing references to and description of the Voting Agreement do not purport to be complete and are subject, and are qualified in their entirety by reference, to the full text of the Voting Agreement, which is incorporated by reference in this Item 6.

Item 7 of this Schedule 13D is hereby amended to include the following information:

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein, and intending to be legally bound hereby, the parties hereby agree, severally and not jointly, as follows:

1. Voting of Shares. During the period from the date of this Agreement through the Expiration Date, at every meeting of the stockholders of the Company called with respect to any of the following, each Stockholder shall vote or cause to be voted the Subject Shares then owned by such Stockholder that such Stockholder is entitled to vote at such meeting (a) for the approval of (i) an amendment to the certificate of incorporation of the Company authorizing a sufficient number of Shares to permit the exercise in full of the Warrants and (ii) the authorization of such exercise in full under the rules of The NASDAQ Global Select Market, in each case, for the avoidance of doubt, without giving effect to any “cashless” or “net” exercise provisions therein and (b) against any other action or agreement that would reasonably be expected to impede, frustrate, interfere with, delay, postpone or adversely affect the transactions contemplated by the Investment Agreement.

2. Transfer of Shares. During the period from the date of this Agreement until the date of the Company’s annual stockholders’ meeting to be held in 2016 (the “2016 Annual Meeting”), each Stockholder will not, directly or indirectly, (a) transfer, assign, sell, pledge, encumber, hypothecate or otherwise dispose (whether by sale, liquidation, dissolution, dividend or distribution) of or consent to any of the foregoing (“Transfer”), or cause to be Transferred, any of the Subject Shares; provided, that nothing in this clause (a) shall prohibit Transfers from any Stockholder(s) to any other Stockholder(s), (b) deposit any of the Subject Shares into a voting trust or enter into a voting agreement or arrangement with respect to the Subject Shares or grant any proxy or power of attorney with respect thereto that is inconsistent with this Agreement, (c) enter into any contract, option or other arrangement or undertaking with respect to the Transfer of any Shares (except as permitted by the proviso in clause (a)) or (d) take any other action, that would materially restrict, limit or interfere with the performance of such Stockholder’s obligations hereunder.

The execution, delivery and performance by such Stockholder of this Agreement does not require any consent, approval, authorization or permit of, action by, filing with or notification to any Governmental Entity, other than (i) filings under the Securities Exchange Act, as amended and (ii) any consent, approval, authorization, permit, action, filing or notification the failure of which to make or obtain would not, individually or in the aggregate, be reasonably expected to prevent or materially delay such Stockholder’s ability to observe and perform such Stockholder’s material obligations hereunder.

(b) No Conflicts. Neither the execution and delivery of this Agreement, nor the performance of such Stockholder’s obligations hereunder, nor compliance with the terms hereof, will violate, conflict with or result in a breach of, or constitute a default (with or without notice or lapse of time or both) under any provision of, any trust agreement, loan or credit agreement, note, bond, mortgage, indenture, lease or other agreement, instrument, permit, concession, franchise, license, judgment, order, notice,

2

decree, statute, law, ordinance, rule or regulation applicable to such Stockholder or to such Stockholder’s property or assets, except where any such breach or default would not, individually or in the aggregate, be reasonably expected to prevent or materially delay such Stockholder’s ability to observe and perform such Stockholder’s material obligations hereunder.

(c) The Subject Shares. As of the date hereof, such Stockholder is the record and beneficial owner of the Subject Shares set forth opposite such Stockholder’s name on Schedule A hereto, free and clear of any and all security interests, liens, changes, encumbrances, equities, claims, options or limitations of whatever nature and free of any other limitation or restriction (including any restriction on the right to vote, sell or otherwise dispose of such Subject Shares), other than any of the foregoing that would not prevent or delay such Stockholder’s ability to perform such Stockholders obligations hereunder. As of the date hereof, such Stockholder does not own, of record or beneficially, any shares of capital stock of the Company other than the Subject Shares set forth opposite such Stockholder’s name on Schedule A hereto. The Stockholders have, or will have at the time of the applicable stockholders’ meeting, the sole right to vote or direct the vote of, or to dispose of or direct the disposition of, the Subject Shares set forth opposite such Stockholder’s name on Schedule A hereto to the extent then owned by such Stockholder, and none of the Subject Shares set forth opposite such Stockholder’s name on Schedule A hereto is subject to any agreement, arrangement or restriction with respect to the voting of such Subject Shares that would prevent or delay a Stockholder’s ability to perform its obligations hereunder.

5. Representations and Warranties of the Company. The Company represents and warrants to the Stockholders as follows: The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware and has full corporate power and authority to execute and deliver this Agreement and to perform its obligations hereunder. The execution and delivery of this Agreement by the Company and the performance of its obligations hereunder have been duly and validly authorized by the Board of Directors of the Company, and no other corporate proceedings on the part of the Company are necessary to authorize the execution, delivery and performance of this Agreement and the performance of its obligations hereunder. The Company has duly and validly executed this Agreement, and

3

this Agreement constitutes a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization or other similar laws affecting creditors’ rights generally and by general equitable principles (regardless of whether enforceability is considered in a proceeding in equity or at law).

6. Stockholder Capacity. No Person executing this Agreement who is or becomes during the term hereof a director or officer of the Company shall be deemed to make any agreement or understanding in this Agreement in such Person’s capacity as a director or officer. Each Stockholder is entering into this Agreement solely in such Stockholder’s capacity as the record holder or beneficial owner of Subject Shares and nothing herein shall limit or affect any actions taken (or any failures to act) by a Stockholder in such Stockholder’s capacity as a director or officer of the Company or by any other director or officer of the Company acting in such Person’s capacity as a director or officer of the Company. The taking of any actions (or any failures to act) by a Stockholder in such Stockholder’s capacity as a director or officer of the Company (or by any other director or officer of the Company acting in such Person’s capacity as such) shall not be deemed to constitute a breach of this Agreement, regardless of the circumstances related thereto.

7. Termination. This Agreement shall automatically terminate without further action by any party hereto upon the earliest to occur (the “Expiration Date”) of (a) the approval by the requisite number of the Company’s stockholders at an annual or special meeting of the matters described in Section 1(a), (b) the termination of the Investment Agreement in accordance with its terms, (c) the written agreement of the Stockholders, the Company and Amazon to terminate this Agreement, and (d) immediately after the Company’s annual stockholders’ meeting to be held in calendar year 2017.

8. Specific Performance. Each Stockholder acknowledges and agrees that (a) the covenants, obligations and agreements applicable to it contained in this Agreement relate to special, unique and extraordinary matters, (b) Amazon is relying on such covenants in connection with entering into the Investment Agreement and (c) a violation of any of the terms of such covenants, obligations or agreements will cause Amazon irreparable injury for which adequate remedies are not available at law and for which monetary damages are not readily ascertainable. Therefore, each Stockholder agrees that Amazon shall be entitled to an injunction, restraining order or such other equitable relief (without the requirement to post bond) as a court of competent jurisdiction may deem necessary or appropriate to restrain such Stockholder from committing any violation of such covenants, obligations or agreements. These injunctive remedies are cumulative and shall be Amazon’s sole remedy under this Agreement unless Amazon shall have sought and been denied injunctive remedies, and such denial is other than by reason of the absence of violation of such covenants, obligations or agreements.

4

9. Governing Law; Jurisdiction. This Agreement shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. In addition, each of the parties (a) submits to the personal jurisdiction of the Delaware Court of Chancery in and for New Castle County, or in the event (but only in the event) that such Delaware Court of Chancery does not have subject matter jurisdiction over such dispute, the United States District Court for the District of Delaware, or in the event (but only in the event) that such United States District Court also does not have jurisdiction over such dispute, any Delaware State court sitting in New Castle County, in the event any dispute (whether in contract, tort or otherwise) arises out of this Agreement or the transactions contemplated hereby, (b) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, and (c) agrees that it shall not bring any claim, action or proceeding relating to this Agreement or the transactions contemplated hereby in any court other than the Delaware Court of Chancery in and for New Castle County, or in the event (but only in the event) that such Delaware Court of Chancery does not have subject matter jurisdiction over such claim, action or proceeding, the United States District Court for the District of Delaware, or in the event (but only in the event) that such United States District Court also does not have jurisdiction over such claim, action or proceeding, any Delaware State court sitting in New Castle County. Each party agrees that service of process upon such party in any such claim, action or proceeding shall be effective if notice is given in accordance with the provisions of this Agreement.

10. WAIVER OF JURY TRIAL. EACH PARTY HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM, ACTION OR PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.

11. Amendment. No amendment of any provision of this Agreement shall be effective unless made in writing and signed by Amazon, the Company and each of the Stockholders.

12. Waivers, etc. No waiver shall be effective unless it is in writing signed by the waiving party that makes express reference to the provision or provisions subject to such waiver.

5

13. Assignment. Neither this Agreement nor any right, remedy, obligation nor liability arising hereunder or by reason hereof shall be assignable by any party without the prior written consent of the other parties, and any attempt to assign any right, remedy, obligation or liability hereunder without such consent shall be void, except that Amazon may transfer or assign, in whole or from time to time in part, to one or more of its direct or indirect wholly owned subsidiaries, its rights and/or obligations under this Agreement, but any such transfer or assignment shall not relieve Amazon of its obligations hereunder. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.
