There are no rights of appraisal or similar rights of dissenters arising from matters to be acted on at the meeting.

WHO IS PAYING THE SOLICITATION COST

The expense of preparing, posting online, and printing and mailing any requested hard copies of proxy solicitation materials will be borne by the Company.

NOTICE OF INTERNET AVAILABILITY OF PROXY MATERIALS

Pursuant to rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to provide our stockholders access to our proxy materials via the internet. Accordingly, we are sending a Notice of Internet Availability of Proxy Materials (the “Notice”) to our stockholders. All stockholders will have the ability to access the proxy materials on the website referenced in the Notice or request to receive a printed set of the proxy materials. The Notice contains instructions on how to access the proxy materials over the internet, how to vote online, and how to request a printed copy of the materials. We encourage you to take advantage of the proxy materials on the internet. By opting to access your proxy materials online, you will save us the cost of producing and mailing documents, reduce the amount of mail you receive, and allow us to conserve natural resources.

WHO CAN VOTE

Only stockholders of record holding shares of the Company’s Class A Common Stock and stockholders of record holding shares of the Company’s Class C common stock, par value $0.0001 per share (“Class C Common Stock” and, together with Class A Common Stock, the “common stock”), at the close of business on the record date, March 23, 2020, are entitled to receive notice of the annual meeting and to vote the shares of common stock they held on that date.

1

As of February 29, 2020, there were 324,929,305 shares of Altus common stock issued and outstanding, including 74,929,305 shares of Class A Common Stock and 250,000,000 shares of Class C Common Stock. Holders of Altus common stock are entitled to one vote per share, voting together as a single class, and are not allowed to cumulate votes in the election of directors.

The Company’s stock transfer books will not be closed. A complete list of stockholders entitled to vote at the annual meeting will be available for examination by any Altus stockholder at One Post Oak Central, 2000 Post Oak Boulevard, Suite 100, Houston, Texas 77056-4400, for purposes relating to the annual meeting, during normal business hours for a period of ten days before the meeting.

HOW TO VOTE

If your shares of Altus common stock are held by a broker, bank, or other nominee (in “street name”), you will receive instructions from them on how to vote your shares. If your shares are held by a broker and you do not give the broker specific instructions on how to vote your shares, your broker may vote your shares at its discretion on “routine” matters to be acted upon at the annual meeting. However, your shares will not be voted on any of the “non-routine” matters described below. An absence of voting instructions on any “non-routine” matters will result in a “broker non-vote.”

The only “routine” matters to be acted upon at the annual meeting are:

• Proposal 2: Ratification of the appointment of EY as the Company’s independent auditor for fiscal year 2020; and

• Proposal 4: Approval of the Reverse Stock Split Proposal.

All other matters to be acted upon at the annual meeting are “non-routine” matters. As such, if you hold all or any portion of your shares in street name and you do not give your broker or bank specific instructions on how to vote your shares, your shares will not be voted on any of the following “non-routine” matters:

• Proposal 1: Election of the eleven directors named in this proxy statement; and

• Proposal 3: Approval of the Share Issuance Proposal.

If you hold shares of Altus common stock in your own name (as a “stockholder of record”), you may instruct the Company on how to vote your shares:

• over the internet, by following the instructions provided in the Notice; or

• if you requested to receive printed proxy materials:

• by scanning the QR code on the enclosed proxy card with your mobile device (specific directions for using the mobile voting system are shown on the proxy card);

• by using the toll-free telephone number listed on the enclosed proxy card (specific directions for using the telephone voting system are included on the proxy card); or

• by marking, signing, dating, and returning the enclosed proxy card in the postage-paid envelope provided.

When using internet, mobile device, or telephone voting, the voting systems will verify that you are a stockholder through the use of a “company number” for Altus and a unique “control number” for you.

Whichever method you use to transmit your instructions, your shares of Altus common stock will be voted as you direct. If you designate the proxies named on the proxy card to vote on your behalf, but do not specify how to vote your shares, they will be voted as follows:

• Proposal 1: FOR ALL NOMINEES for the election of directors;

2

• Proposal 2: FOR the ratification of the appointment of EY as the Company’s independent auditor for fiscal year 2020;

• Proposal 3: FOR the approval of the Share Issuance Proposal;

• Proposal 4: FOR the approval of the Reverse Stock Split Proposal; and

• In accordance with the judgment of the persons voting the proxy on any other matter properly brought before the meeting.

If you vote in advance using one of the methods described above, then you may still attend and vote at the meeting. Please see Revoking a Proxy below for additional details.

We take the health and welfare of our stockholders, directors, officers, and employees seriously. As part of our precautions regarding COVID-19, we are planning for the possibility that the annual meeting may be postponed or held by means of remote communication. If alternative arrangements are implemented, then the Company will issue a press release detailing such changes. The press release will be posted on the Company’s website and filed with the SEC as additional proxy materials. A remote meeting will have no impact on your ability to submit your proxy by internet or, if you requested to receive printed proxy materials, by telephone, by scanning the QR code on your proxy card with your mobile device, or by marking, signing, dating, and returning your proxy card, each as explained in more detail above. If you are planning to attend the annual meeting, please check the Company’s website prior to the meeting date. As always, you are encouraged to vote your shares prior to the annual meeting date.

REVOKING A PROXY

You may revoke a proxy before it is voted by submitting a new proxy with a later date by internet, mobile device, telephone, or mail (if applicable), by voting at the meeting, or by filing a written revocation with the Company’s corporate secretary. Your attendance at the annual meeting alone will not automatically revoke your proxy.

QUORUM

The presence at the annual meeting, in person or by proxy, of the holders of a majority of the shares of Altus common stock outstanding on the record date entitled to vote at the annual meeting will constitute a quorum, permitting the business of the meeting to be conducted.

VOTES NEEDED

Election of Directors

The election of directors will be determined by a plurality of the votes cast by the stockholders present in person or represented by proxy at the annual meeting and entitled to vote thereon. This means that a director nominee will be elected if the nominee receives more FOR votes than any other nominee for the same director position. You may vote FOR ALL NOMINEES, you may WITHHOLD AUTHORITY FOR ALL NOMINEES, or you may vote FOR ALL EXCEPT one or more nominees. Only votes FOR the election of a director nominee will be counted. Abstentions and broker non-votes count for quorum purposes but not for purposes of the election of directors. Cumulative voting is not permitted in the election of directors.

Ratification of the Appointment of Independent Auditor

The affirmative vote of a majority of the votes cast by the stockholders present in person or represented by proxy at the annual meeting and entitled to vote thereon is required for the ratification of the appointment of EY as the Company’s independent auditor. This means that the proposal will be approved only if the shares voted FOR the proposal exceed the number voted AGAINST the proposal. You may vote FOR or AGAINST the proposal or you may ABSTAIN. Votes cast FOR or AGAINST approval of this matter will be counted as shares entitled to vote on the matter. Broker non-votes will also be counted as shares entitled to vote on this matter. Abstentions will count for quorum purposes but will not count as shares entitled to vote on this matter.

3

Approval of the Share Issuance Proposal

The affirmative vote of a majority of the votes cast by the stockholders present in person or represented by proxy at the annual meeting and entitled to vote thereon is required for approval of the Share Issuance Proposal. This means that the proposal will be approved only if the shares voted FOR the proposal exceed the number voted AGAINST the proposal. You may vote FOR or AGAINST the proposal or you may ABSTAIN. Only votes cast FOR or AGAINST approval of this matter will be counted as shares entitled to vote on the matter. Abstentions and broker non-votes will count for quorum purposes but will not count as shares entitled to vote on this matter.

Approval of the Reverse Stock Split Proposal

The affirmative vote of a majority of the votes cast by the stockholders present in person or represented by proxy at the annual meeting and entitled to vote thereon is required for approval of the Reverse Stock Split Proposal. This means that the proposal will be approved only if the shares voted FOR the proposal exceed the number voted AGAINST the proposal. You may vote FOR or AGAINST the proposal or you may ABSTAIN. Votes cast FOR or AGAINST approval of this matter will be counted as shares entitled to vote on the matter. Broker non-votes will also be counted as shares entitled to vote on this matter. Abstentions will count for quorum purposes but will not count as shares entitled to vote on this matter.

Notwithstanding approval of the Reverse Stock Split Proposal by our stockholders, the Board reserves its right to elect not to proceed with the reverse stock split at any time prior to the date on which the amendment to the Company’s Second Amended and Restated Certificate of Incorporation becomes effective pursuant to the General Corporation Law of the State of Delaware (the “DGCL”), if it determines, in its sole discretion, that the reverse stock split is no longer necessary to maintain the listing of the Company’s Class A Common Stock on the Nasdaq or is no longer in the best interests of the Company or its stockholders. Subject to receipt of stockholder approval of the Reverse Stock Split Proposal, the Board currently expects and intends to implement the reverse stock split following the annual meeting.

Other Business

The affirmative vote of a majority of the votes cast by the stockholders present in person or represented by proxy at the annual meeting and entitled to vote thereon is required for approval of any other business that may properly come before the meeting or any adjournment thereof. Only votes FOR or AGAINST approval of any other business will be counted as shares entitled to vote on such matters. Abstentions and broker non-votes will count for quorum purposes but will not count as shares entitled to vote on such matters.

WHO COUNTS THE VOTES

Representatives of American Stock Transfer & Trust Company, LLC will tabulate the votes. The Company will appoint representatives to act as inspectors of the election.

PROPOSAL 1. ELECTION OF DIRECTORS

General Information

Our second amended and restated certificate of incorporation provides that the number of directors serving on our Board shall be fixed from time to time by majority approval of our Board. Our Board has set the number of directors at eleven. The current terms of directors Mark Borer, Clay Bretches, Staci L. Burns, C. Doug Johnson, D. Mark Leland, Kevin S. McCarthy, Christopher J. Monk, Stephen P. Noe, Robert S. Purgason, Ben C. Rodgers, and Jon W. Sauer will expire at the annual meeting. Each of the current directors has been nominated for election to our Board at the annual meeting. As such, if each of the nominees named below is elected to our Board, there will be no vacancies on our Board following the annual meeting. Each director shall be elected for a one-year term and hold office until the next annual meeting and until his or her successor has been elected and qualified, subject, however, to such director’s earlier death, resignation, retirement, disqualification, or removal.

In connection with the closing of our initial business combination, on November 9, 2018, we entered into a stockholders agreement (the “Stockholders Agreement”) with Apache Midstream LLC (“Apache Midstream”) and Kayne Anderson Sponsor, LLC (“Kayne Anderson Sponsor”) to set forth certain corporate governance rights of Apache Midstream and Kayne Anderson Sponsor. Pursuant to the Stockholders Agreement, Kayne Anderson Sponsor is entitled to nominate two directors to our Board to serve until the earlier of the time that Kayne Anderson Sponsor and its affiliates own less than 1% of our outstanding voting common stock or the second anniversary of the date of the Stockholders Agreement and until their successors have been elected and qualified, subject, however, to each such director’s earlier death, resignation, retirement, disqualification, or removal. Additionally, under the Stockholders Agreement, Apache Midstream is entitled to nominate a certain number of directors to our Board based on its and its affiliates’ ownership of our outstanding voting common stock as follows:

Apache Midstream Ownership Threshold	Number of Directors
50% or more		7
40% or more but less than 50%		6
30% or more but less than 40%		5
20% or more but less than 30%		4
10% or more but less than 20%		3
5% or more but less than 10%		2
1% or more but less than 5%		1

For so long as Kayne Anderson Sponsor is entitled to nominate directors as provided above and Apache Midstream and its affiliates own 50% or more of our outstanding voting common stock, at least one of the directors nominated by Apache Midstream will be an “independent director” in accordance with applicable listing rules of the Nasdaq Stock Market (“Nasdaq”). Further, we have agreed to include at least one director nominated by Apache Midstream on each committee of our Board, unless such inclusion would violate applicable securities laws or stock exchange or stock market rules.

Pursuant to the Stockholders Agreement, Apache Midstream may nominate six non-independent directors and one independent director for election at the annual meeting, and it has nominated each of Mr. Bretches, Ms. Burns, Mr. Johnson, Mr. Monk, Mr. Noe, Mr. Rodgers, and Mr. Sauer. Pursuant to the Stockholders Agreement and certain conditions, Kayne Anderson Sponsor may nominate two directors for election at the annual meeting, and it has nominated each of Mr. McCarthy and Mr. Purgason. In addition, our Board has nominated each of Mr. Borer and Mr. Leland for election at the annual meeting.

5

Unless otherwise instructed, all proxies will be voted in favor of these nominees. If one or more of the nominees is unwilling or unable to serve, the proxies will be voted only for the remaining named nominees. Proxies cannot be voted for more than eleven nominees. Each director nominee has consented to be named in this proxy statement, and the Board knows of no nominee for director who is unwilling or unable to serve.

THE BOARD RECOMMENDS THAT YOU VOTE “FOR ALL NOMINEES” FOR THE ELECTION OF DIRECTORS.

Director Independence

Apache Midstream beneficially owns a majority of our outstanding voting common stock. As a result, we qualify as a “controlled company” within the meaning set forth in the Nasdaq listing rules and may elect not to comply with certain Nasdaq corporate governance requirements, including the requirements that our Board consist of a majority of independent directors and that our compensation committee and nominating and governance committee (if such a committee is established) be composed entirely of independent directors. We have elected to utilize these exemptions, and as a result, our Board is not comprised of a majority of independent directors, and we have individuals serving on our Compensation Committee (as defined below) that are not considered independent under the Nasdaq listing rules and the rules and regulations of the SEC. These independence requirements will not apply to us as long as we remain a controlled company.

Our Board has determined that Messrs. Borer, Leland, and Johnson are independent within the meaning of Nasdaq Rule 5605(a)(2).

Reporting of Concerns to Independent Directors

Anyone who has concerns about the Company may communicate those concerns to the independent directors. Such communication should be mailed to the Company’s corporate secretary at One Post Oak Central, 2000 Post Oak Boulevard, Suite 100, Houston, Texas 77056-4400, and the corporate secretary will forward such communications to the independent directors.

Board Leadership Structure and Role in Risk Oversight

Board Leadership Structure

Our Board does not have a formal policy with respect to whether the position of Chairman of the Board may be filled by the Company’s Chief Executive Officer. Instead, our Board has adopted a fluid approach to the Board’s leadership structure that allows for variations depending on the circumstances and changing needs of the Company over time. While our Board has previously separated the roles of Board Chairman and Chief Executive Officer, on April 2, 2020, our Board unanimously appointed Mr. Bretches, the Company’s Chief Executive Officer and President, to serve as Chairman of the Board.

Our Board believes that this combined structure will help to ensure clarity regarding leadership of the Company, will allow the Company to speak with one voice and will provide for efficient coordination of board action, particularly in times of change. The combination of the Board Chairman’s ability to call board meetings and the Chief Executive Officer’s intimate knowledge of our business, including our risk management framework, provides a strong structure for the efficient operation of our Board process and effective leadership of our Board overall. This structure also avoids potential confusion as to leadership roles and duplication of efforts that can result from the roles being separated. It also assists our Chief Executive Officer in managing the Company and dealing with third parties more effectively on a day-to-day basis.

Our Board does not currently have a lead director. However, our Board regularly reviews all aspects of its governance profile, including the role of lead director, and will make changes as circumstances warrant.

Board Role in Risk Oversight

The goal of the Company’s risk management process is to understand and manage risk; management is responsible for identifying and managing the risks, while directors provide oversight to management in this process. Our Audit Committee, as further described below, is primarily responsible for overseeing the Company’s financial risk management processes on behalf of the Board. The Audit Committee charter provides that the Audit Committee should review, assess, and discuss with management (and, if appropriate, the independent auditor) major financial risk exposures and the manner in which such risks are being monitored and

12

controlled. In addition, the Audit Committee reports to the Board with respect to the committee’s activities, and based on the information provided by the committee, the Board also considers the Company’s entire risk profile.

The Audit Committee and the Board endeavor to ensure that the risks undertaken are consistent with the Board’s tolerance for risk. While the Board is responsible for setting, monitoring, and maintaining the Company’s risk management processes, the Company’s executive officers and members of our management team are responsible for implementing and overseeing our day-to-day risk management. Additionally, the Company’s management participate in Apache’s Corporate Risk Management Committee. The Corporate Risk Management Committee monitors and manages risks and is tasked with, among other things, ensuring sound policies, procedures, and practices are in place to address corporate-wide management of risks, including those of its controlled subsidiaries, such as the Company. The Company believes that this division of responsibility is the most effective way to monitor and control risk.

In addition to the oversight provided by our full Board, Audit Committee, executive officers, and the members of our management team, our independent directors hold regularly-scheduled executive sessions as often as they deem appropriate. These executive sessions provide an additional avenue through which we monitor the Company’s risk exposure and processes regarding risk management.

Standing Committees and Meetings of the Board

Our Board has an Audit Committee, a Conflicts Committee, and a Compensation Committee. Actions taken by these committees are reported to our Board at the next regularly scheduled Board meeting. During 2019, each of the Company’s continuing directors attended or participated in at least 75 percent of all meetings of our Board and the committees of which he or she was a member that were held following the date of his or her appointment. All then-current directors attended the Company’s 2019 annual meeting of stockholders held on May 30, 2019.

Chairman of the Board

Committee Chairman

Audit Committee

We have established an Audit Committee of our Board. Messrs. Borer, Johnson, and Leland are members of our Audit Committee, with Mr. Johnson serving as chair. Under the Nasdaq listing rules and applicable SEC rules, we are required to have three members of the Audit Committee, all of whom must be independent. Messrs. Borer, Johnson, and Leland meet the independent director standard under Nasdaq listing rules and under Rule 10A-3(b)(1) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Board has determined that Mr. Johnson qualifies as a financial expert, as defined in Item 407 of Regulation S-K under the Securities Act of 1933, as amended (the “Securities Act”).

13

We have adopted an Audit Committee charter, which provides that the principal function of the Audit Committee is to oversee our accounting and financial reporting processes and the audit of our financial statements, including:

• the integrity of our financial statements;

• our compliance with legal and regulatory requirements;

• the qualifications, performance, and independence of the independent auditor engaged by us for the purpose of preparing or issuing an audit report or performing other audit, review, or attest services;

• the performance of our internal audit function;

• the preparation of the Audit Committee report required by the SEC, as included in this proxy statement; and

• the fulfillment of the other responsibilities set out in the charter.

As described more fully in Board Role in Risk Oversight above, the Audit Committee is also tasked with reviewing the guidelines and policies governing the process by which our senior management and our relevant departments assess and manage our exposure to risk. In addition, the Audit Committee oversees our major financial risk exposures and the steps management has taken to monitor and control such exposures.

Compensation Committee

We have established a Compensation Committee of our Board. The Nasdaq corporate governance requirement that listed companies have a compensation committee composed entirely of independent directors will not apply to us as long as we remain a controlled company. As such, Messrs. Purgason and Sauer serve as members of our Compensation Committee, with Mr. Sauer serving as chair.

We have adopted a Compensation Committee charter, which details the principal functions of the Compensation Committee, including:

• reviewing and approving on an annual basis the corporate goals and objectives relevant to our Chief Executive Officer’s compensation, if any is paid by us, evaluating our Chief Executive Officer’s performance in light of such goals and objectives, and determining and approving the remuneration (if any) of our Chief Executive Officer based on such evaluation;

• reviewing and approving on an annual basis the compensation, if any is paid by us, of all of our other officers;

• reviewing on an annual basis our executive compensation policies and plans;

• implementing and administering our incentive compensation equity-based remuneration plans;

• assisting management in complying with our proxy statement and annual report disclosure requirements;

• approving all special perquisites, special cash payments, and other special compensation and benefit arrangements for our officers and employees;

• if required, producing a report on executive compensation to be included in our annual proxy statement; and

• reviewing, evaluating, and recommending changes, if appropriate, to the remuneration for directors.

The Compensation Committee charter also provides that the Compensation Committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, legal counsel, or other adviser and will be directly responsible for the appointment, compensation, and oversight of the work of any such adviser. However, before engaging or receiving advice from a compensation consultant, external legal counsel, or any other adviser, the Compensation Committee will consider the independence of each such adviser, including the factors required by Nasdaq and the SEC.

14

The Compensation Committee may form subcommittees for any purpose that the Compensation Committee deems appropriate and may delegate to such subcommittees such power and authority as the Compensation Committee deems appropriate; provided, however, that no subcommittee shall consist of fewer than two members; and provided further that the Compensation Committee shall not delegate to a subcommittee any power or authority required by any law, regulation, or listing standard to be exercised by the Compensation Committee as a whole.

The Chief Executive Officer may make, and the Compensation Committee may consider, recommendations to the Compensation Committee regarding the Company’s compensation and employee benefit plans and practices, including its executive compensation plans, its incentive-compensation and equity-based plans with respect to executive officers (other than the Chief Executive Officer), and the Company’s director compensation arrangements.

Conflicts Committee

We have established a Conflicts Committee of our Board. Messrs. Borer, Johnson, and Leland serve as members of our Conflicts Committee, with Mr. Leland serving as chair. The primary purpose of the Conflicts Committee is to resolve potential conflicts of interest in connection with certain related-party transactions between the Company or any of its subsidiaries, on the one hand, and Apache or any of its subsidiaries other than the Company and its subsidiaries, on the other hand. In accordance with the related-party transaction policy adopted by our Board on the consummation of our initial business combination, our management team is required to present the following transactions to the Conflicts Committee for review and approval:

• related-party transactions that are not pre-approved under the related-party transaction policy and involve an aggregate amount paid to or by the Company or its subsidiaries of more than $20 million over the life of the transaction or more than $5 million per calendar year (a “Material Amount”);

• any amendment of, or waiver of any right or remedy under, certain agreements involving the Company, the Company’s subsidiaries, Apache, Apache’s subsidiaries, or certain third parties by the Company or its subsidiaries or any related party acting on behalf of such persons (as opposed to a related party acting on its own behalf), which amendment or waiver involves a Material Amount or, if the amount involved cannot be quantified, would be material and adverse to the Company and its subsidiaries, taken as a whole;

• the enforcement, or the failure to enforce, by the Company or its subsidiaries or a related party acting on behalf of the Company or its subsidiaries (as opposed to a related party acting on its own behalf) of any rights or remedies of the Company or its subsidiaries against a related party under any of the agreements described in the immediately preceding bullet that involves a Material Amount or, if the amount involved cannot be quantified, would be material and adverse to the Company and its subsidiaries, taken as a whole; provided that budgeting, contracting, and other operational matters under any such agreements will not be subject to the provisions of this bullet and the immediately preceding bullet; and

• the entry into any gas processing agreement or gas gathering agreement between the Company or any of its subsidiaries and any person other than a related party, or the amendment of any such agreement, that causes a related party to have a right to cause certain amendments to our gas processing agreement or gas gathering agreement with Apache, the effect of which would involve a reduction in the amounts payable by such related party to the Company or its subsidiaries under such gas processing agreement or gas gathering agreement, respectively, by a Material Amount.

Agreements entered into in connection with the initial business combination have not been and will not be subject to the review and approval of the Conflicts Committee. In addition, except as provided above, the exercise or waiver of any rights or remedies by the applicable related party (acting on its own behalf and/or acting on behalf of us or our subsidiaries) under any agreement entered into in connection with the initial

15

business combination, including with respect to budgets, contracting, and/or other operational matters, are deemed to be pre-approved transactions under the related party transactions policy.

Director Nominations

We do not have a standing nominating committee. In accordance with Rule 5605(e)(1)(A) of the Nasdaq listing rules, a majority of the independent directors may recommend a director nominee for selection by the Board. Our Board believes that the independent directors can satisfactorily carry out the responsibility of properly selecting or approving director nominees without the formation of a standing nominating committee. As there is no standing nominating committee, we do not have a nominating committee charter in place.

The Board also will consider director candidates recommended for nomination by our stockholders during such times as they are seeking proposed nominees to stand for election at the next annual meeting of stockholders, or, if applicable, a special meeting of stockholders. Our stockholders that wish to nominate a director for election to our Board should follow the procedures set forth in our bylaws.

We have not formally established any specific, minimum qualifications that must be met or skills that are necessary for directors to possess. In general, in identifying and evaluating nominees for director, our Board considers educational background, diversity of professional experience, knowledge of our business, integrity, professional reputation, independence, wisdom, and the ability to represent the best interests of our stockholders.

Committee Charters

You can access electronic copies of the charters of the Audit Committee and Compensation Committee of the Board, each as amended from time to time, on the Company’s website, www.altusmidstream.com. Our Code of Business Conduct, which meets the requirements of a code of ethics under applicable SEC regulations and Nasdaq corporate governance requirements, also is available on the Company’s website. You may request printed copies of any of these documents by writing to the Company’s corporate secretary at One Post Oak Central, 2000 Post Oak Boulevard, Suite 100, Houston, Texas 77056-4400.

Compensation Committee Interlocks and Insider Participation

During 2019, W. Mark Meyer, who resigned as a director and the Chairman of our Board on March 31, 2020, and Messrs. Purgason and Sauer served on the Compensation Committee of the Company’s Board.

No executive officer of the Company serves, or in the past year has served, as a member of the compensation (or similar) committee or on the board of directors of another entity, one of whose executive officers served on the Company’s Compensation Committee or as a member of the Company’s Board. During fiscal year 2019, Messrs. Meyer and Sauer served as officers of the Company, with Mr. Meyer having served as the Company’s Senior Vice President, Energy Technology, Data Analytics & Commercial Intelligence and Mr. Sauer having served as the Company’s Senior Vice President. During fiscal year 2019, no member of the Compensation Committee had any business relationship or conducted any business with the Company other than as an officer or director of the Company.

Report of the Audit Committee

The following report of the Audit Committee shall not be deemed to be “soliciting material” or to be “filed” with the SEC, nor shall this report be incorporated by reference into any filing made by the Company under the Securities Act or the Exchange Act.

The Audit Committee is operated under a charter that specifies the scope of the Committee’s responsibilities. The charter, which is reviewed annually and available on the Company’s website, www.altusmidstream.com, was last amended and restated effective February 11, 2020.

The Board has determined that all three members of the Committee are independent based upon the standards adopted by the Board, which incorporate the independence requirements under applicable laws, rules, and regulations, including standards of the Nasdaq and Rule 10A-3 of the Exchange Act.

The Company’s management has the primary responsibility for preparing the Company’s financial statements, managing the accounting and financial reporting processes, devising and maintaining the systems of internal controls over financial reporting, and assessing the effectiveness of internal controls over financial reporting. Ernst & Young LLP, the Company’s independent registered public accounting firm (the “independent auditor”), is responsible for the audit of the consolidated financial statements. The Company qualifies as an “emerging growth company” as defined in the Jumpstart Our Business Startups (JOBS) Act and is therefore exempt from the independent auditor attestation requirement in the assessment of the Company’s internal controls over financial reporting pursuant to the Sarbanes-Oxley Act of 2002. As a result, the independent auditor did not issue a report on the Company’s internal controls over financial reporting for the year ended December 31, 2019. The Committee’s responsibility is to monitor and oversee these processes and procedures on behalf of the Board.

The Audit Committee held nine meetings during fiscal year 2019, including four in-person meetings. The Audit Committee also held three meetings, including one in person, in early 2020 pertinent to the fiscal year 2019 audit procedures. The meetings of the Audit Committee are designed to facilitate and encourage communication among the Audit Committee, the Company, the Company’s internal audit function, and the Company’s independent auditor. Meeting agendas are set based upon the Audit Committee charter and also include suggested topics from Committee members and/or other relevant topics. At some of the in-person Audit Committee meetings, the Committee met with the internal auditors and the independent auditor, with and without management present, to discuss the results of their examinations, their evaluations of the Company’s internal controls, including internal controls over financial reporting, and the overall quality of the Company’s financial reporting.

The Committee is responsible for oversight of the qualifications, independence, and performance of the Company’s independent auditor and annually determines whether to retain the Company’s current independent auditor or retain another auditor. In doing so, the Audit Committee also considers whether, in order to assure continuing auditor independence, there should be regular rotation of the independent auditor, which includes consideration of the advisability and potential impact of selecting a different independent auditor.

In its determination to retain the current independent auditor in 2019, the Audit Committee took into consideration a number of factors, including the historical and recent performance of the independent auditor and lead partner, its knowledge of the Company’s operations and industry, external data relating to audit quality and performance, including recent Public Company Accounting Oversight Board (“PCAOB”) reports, and independence. The Audit Committee recognizes the importance of maintaining the independence of the Company’s independent auditor, in both fact and appearance.

The Audit Committee discussed with the Company’s internal auditors and the independent auditor the overall scope and plans for their respective audits. In addition, the Audit Committee reviewed with the independent auditor, which is responsible for expressing an opinion on the conformity of the Company’s audited consolidated

17

financial statements with U.S. generally accepted accounting principles, its judgments as to the quality, not just the acceptability, of the Company’s accounting principles and such other matters as are required to be discussed with the Audit Committee by the applicable requirements of the PCAOB, including PCAOB Auditing Standard No. 1301, Communications with Audit Committees, the rules of the SEC, and other applicable regulations. In addition, the Audit Committee has discussed with the independent auditor the firm’s independence from Company management and the Company, including the written disclosures and the letter received from the firm as required by PCAOB Rule 3526, Communication with Audit Committees Concerning Independence, and considered the compatibility of non-audit services with the independent auditor’s independence.

The Audit Committee also reviewed and discussed together with management, the internal auditors, and the independent auditor the Company’s audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2019 (the “2019 Annual Report”), including the clarity of disclosures in the financial statements, the results of management’s assessment of the effectiveness of the Company’s internal controls over financial reporting, and the Company’s internal auditors’ audit of the Company’s internal controls over financial reporting.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board that the audited consolidated financial statements be included in the 2019 Annual Report, filed by the Company with the SEC.

Certain Business Relationships and Transactions

The Company’s Board has adopted a Code of Business Conduct, which was last revised in September 2019. The Code of Business Conduct prohibits conflicts of interest between any of our directors, officers, or employees and the Company. The Code of Business Conduct requires our directors, officers, and employees to inform the Company of any transaction that involves related parties and that may give rise to a conflict of interest. The Board reviews transactions to determine whether a transaction impairs the independence of a director and such determination is documented in the Board’s minutes. The Code of Business Conduct is available on the Company’s website, www.altusmidstream.com.

Midstream Service Agreements

Apache has been our primary and most significant customer since operations commenced in the second quarter of 2017, although we are pursuing additional third-party business, which could be accommodated by existing and planned capacity. We have contracted to provide gas gathering, compression, processing, transmission, and natural gas liquids transmission services pursuant to acreage dedications provided by Apache. Revenues under these contracts are 100 percent fee-based, resulting in no direct commodity price exposure attributable to these contracts.

In addition, Apache agreed that any gas produced from Apache-operated wells located within the dedication area that is owned by other working interest owners and royalty owners is dedicated to us, so long as Apache has the right to market such gas. The agreements are effective for primary terms beginning on July 1, 2018 and ending March 31, 2032. The primary term will automatically extend for two five-year periods unless Apache provides at least nine months’ prior written notice of its election not to extend the primary term. The covenants under the agreements are intended to run with the land and will be binding on any transferee of the interests within the dedicated area.

Construction, Operations and Maintenance Agreement

In connection with the closing of our initial business combination, we entered into the Construction, Operations and Maintenance Agreement (the “COMA”) with Apache, pursuant to which Apache provides certain services

23

related to the design, development, construction, operation, management, and maintenance of our assets, on our behalf. We do not have any employees and, pursuant to the COMA, rely on Apache’s employees for the conduct of our business and operations.

Under the COMA, we paid or will pay fees to Apache of (i) $3.0 million from November 9, 2018 through December 31, 2019, (ii) $5.0 million for the period of January 1, 2020 through December 31, 2020, (iii) $7.0 million for the period of January 1, 2021 through December 31, 2021, and (iv) $9.0 million annually thereafter, adjusted based on actual internal overhead and general and administrative costs incurred, until terminated. In addition, Apache may be reimbursed for certain internal costs and third-party costs incurred in connection with its role as service provider under the COMA.

The COMA will continue to be effective until terminated (i) upon the mutual consent of Apache and us, (ii) by either of Apache or us, at our respective options, upon 30 days’ prior written notice in the event Apache or an affiliate of Apache no longer owns a direct or indirect interest in at least 50% of our voting or other equity securities, or (iii) by us if Apache fails to perform any of its covenants or obligations due to willful misconduct of certain key personnel specified in the COMA and such failure has a material adverse financial impact on us. If the COMA is terminated by Apache or us, then we will be required to attract and hire employees to perform the services currently performed by Apache’s employees under the COMA or otherwise contract with third parties for the provision of such services.

During the period beginning on January 1, 2019 and ending on December 31, 2019, we paid Apache an aggregate of $2,627,737.22 for the services provided under the COMA.

Stockholders Agreement

In connection with the closing of our initial business combination, we entered into the Stockholders Agreement with Apache Midstream and Kayne Anderson Sponsor to set forth certain corporate governance rights of Apache Midstream and Kayne Anderson Sponsor. For a description of the Stockholders Agreement, please see the General Information section above.

Lease Agreement

In connection with the closing of our initial business combination, we entered into an operating lease agreement with Apache, relating to the use of certain office buildings and warehouse and storage facilities located in Reeves County, Texas (the “Lease Agreement”). Under the terms of the Lease Agreement, we will pay to Apache on a monthly basis the sum of (i) a base rental charge of $44,500 and (ii) an amount based on Apache’s estimate of the annual costs it incurs in connection with the ownership, operation, repair, and/or maintenance of the facilities. Unpaid amounts accrue interest until settled. The initial term of the Lease Agreement is four years and may be extended by us for three additional, consecutive periods of twenty-four months.

EXECUTIVE COMPENSATION

Executive Compensation Overview

We are managed by Apache, and all of our executive officers are employees of Apache and perform responsibilities for Apache and its affiliates that are unrelated to our business. Because our executive officers are employed by Apache, compensation of our executive officers will be set and paid by Apache under its compensation programs.

While Apache is not party to any employment agreements with any of our executive officers, in connection with the closing of our initial business combination, we entered into the COMA with Apache, pursuant to which, among other matters:

• Apache makes available to us the services of the Apache employees who act as our executive officers;

• we reimburse Apache for the costs associated with the salary, benefits, and other compensation of those Apache employees who allocate substantially all or a proportional part of their time to the management and operation of our business and assets; and

• we pay Apache an escalating annual fee to cover the services provided to us by Apache’s employees who provide services to or on behalf of us, as described under Proposal 1. Election of Directors — Certain Business Relationships and Transactions above, which includes an allocation of overhead costs, including an allocation of salary, benefits, and all other forms of compensation of Apache’s employees who are not included in the reimbursement described in the bullet point above.

Except with respect to any awards that may be granted from time to time under our 2019 Plan and our RSU Plan, our executive officers will not receive any additional compensation directly from us for the services they provide to us.

Once Apache has established the total amount to be paid or awarded to an executive officer regarding services rendered to both the Company and Apache, such total amount is multiplied by a percentage (an “Allocation Percentage”) based on a periodic, good-faith estimate made by Apache’s management of the amount of time that each executive officer devoted to the business of the Company relative to the total time that he or she devoted to the businesses of the Company and Apache. The results of such calculations are presented in this proxy as the executive officers’ compensation, even though the escalating annual fee described above includes the compensation of our executive officers and is less than the total compensation described below. During the fiscal year ended December 31, 2019, the costs associated with the salary, benefits, and other compensation of our Chief Executive Officer and Chief Financial Officer were included in the escalating annual fee and were not separately reimbursed to Apache.

Named Executive Officers

Our “named executive officers” (the “NEOs”) for 2019 were only those two individuals who served as our Chief Executive Officer and the one other individual who served as an executive officer of the Company during 2019 with compensation (calculated using the Allocation Percentage described above) in excess of $100,000. Therefore, our NEOs for 2019 were:

• Clay Bretches, who has served as our Chief Executive Officer and President since January 16, 2019;

• Brian W. Freed, who served as our Chief Executive Officer and President until January 15, 2019; and

• Ben C. Rodgers, who has served as our Chief Financial Officer and Treasurer since November 9, 2018.

26

The following table sets forth each NEO’s Allocation Percentage for 2019:

NEOs	Allocation Percentage
Clay Bretches		100	%
Brian W. Freed		10	%
Ben C. Rodgers		50	%

NEO Compensation Program and Objectives

Given that our NEOs are compensated by Apache under the terms of the COMA as described above, the compensation program and objectives for our NEOs are generally consistent with those for Apache’s named executive officers. The following material elements of Apache’s compensation program are based on information provided to the Company by Apache and do not purport to be a complete discussion and analysis of Apache’s compensation objectives, programs, or practices. For a more complete analysis of the compensation programs at Apache, please review the Compensation Discussion and Analysis section in Apache’s proxy statement for its 2020 annual meeting of shareholders, which is expected to be filed with the SEC on or about April 3, 2020.

The elements of compensation discussed below and Apache’s decisions with respect to the amounts paid or awarded to the Company’s NEOs are not subject to approval by our Board or our Compensation Committee.

The compensation program primarily includes the following elements:

• Base salaries are established to recruit and retain executive talent with experience in oil and gas companies operating in the United States, with a target at peer median and reviewed annually.

• Annual incentive compensation is designed to motivate and reward NEOs to create long-term value by achieving key business objectives, with achievement measured against pre-determined corporate objectives established at the beginning of each year.

• Long-term incentive compensation aligns the long-term interests of NEOs with the long-term interests of stockholders, with awards based on performance shares and restricted stock units (“RSUs”) incorporating relative and absolute metrics, to provide a balanced assessment of long-term performance.

NEOs also receive health, welfare, retirement, and similar benefits applicable to other employees of Apache.

27

Summary Compensation Table

The table below summarizes the compensation for the NEOs for all services rendered to the Company and its subsidiaries during fiscal year 2019. As none of our executive officers were compensated for their services to the Company during fiscal year 2018, no compensation information is provided for such fiscal year. As described above, because the Company does not directly employ or compensate the NEOs, the amounts specified in the table reflect the applicable Allocation Percentage applied to each NEO’s compensation from Apache.

(1) The amount for Mr. Freed reflects salary compensation earned and allocated through January 15, 2019. The amount for Mr. Bretches reflects salary compensation earned and allocated since joining the Company on January 16, 2019.

(2) These amounts reflect the value of RSU awards made during the fiscal year, based upon the aggregate grant date fair value determined in accordance with applicable FASB ASC Topic 718. The RSU awards were granted pursuant to Apache’s 2016 Omnibus Compensation Plan. The discussion of the assumptions used in calculating the aggregate grant date fair value of the RSU awards can be found in Note 14 of the Notes to Consolidated Financial Statements included in Apache’s Annual Report on Form 10-K for the year ended December 31, 2019 (which is not and shall not be deemed to be incorporated by reference herein).

(3) These amounts are paid under Apache’s incentive compensation plan as described under NEO Compensation Program and Objectives above. The amounts for 2019 represent compensation that was earned in 2019 but paid in early 2020.

(4) For additional information on All Other Compensation, see the table and footnotes below.

(5) On January 15, 2019, Mr. Freed resigned as Chief Executive Officer and President of the Company and as a member of the Company’s Board.

All Other Compensation

As described above, because the Company does not directly employ or compensate the NEOs, the amounts specified in the table below reflect the applicable Allocation Percentage applied to each NEO’s compensation from Apache.

Ben C. Rodgers		2019		17,900		9,390		2,057		4,009		—		33,356

(1) Officers, as employees of Apache, participate in two qualified retirement plans. The Apache 401(k) Savings Plan provides a match up to the first eight percent of base pay and incentive bonus, and the Apache Money Purchase Retirement Plan provides an annual six percent contribution by Apache. Additionally, officers can elect to participate in the Apache Non-Qualified Retirement/Savings Plan to defer beyond the limits in the Apache 401(k) Savings Plan and continue contributions by Apache, which exceed the limits in the qualified plans.

(2) Apache provides its U.S. employees with two times their base salary under group term life insurance. Executives receive the first $50,000 of coverage under the same group term life insurance plan, and the remaining amount to bring them up to two times salary is provided in the form of universal life insurance policies.

(3) In addition to the benefits for which all Apache employees are eligible, Apache also covers the cost of a comprehensive annual physical and the full cost of enhanced long-term disability coverage for executive officers.

(4) For executive officers, Apache makes available the services of a financial counseling service provider. If the officer elects to enroll in such services, Apache pays the costs charged by the service provider.

If achievement warrants, 50% of the adjusted RSUs vest upon certification of the performance results and 50% of the adjusted RSUs vest on the first anniversary of the first day following the end of the performance period. As of 12/31/2019, one-year results would have resulted in an 87.5% payout under Apache’s 2019 Performance Share Program had it vested; therefore, the value and amount in the table assumes that target levels of performance are achieved. These units may be paid only in cash.

(7) Vests ratably on 02/01/2020, 01/03/2021, and 01/03/2022. These units may be paid only in cash.

(8) Vests on 12/11/2021.

(9) Vests ratably on 05/23/2020 and 05/23/2021.

(10) Vests ratably on 02/01/2020, 01/03/2021, and 01/03/2022.

(11) Vests ratably on 02/01/2020, 01/03/2021, and 01/03/2022. These units are based on the per-share closing price of Altus’ Class A Common Stock of $2.86 on 12/31/2019 and may be paid only in cash.

PROPOSAL 2. RATIFICATION OF THE APPOINTMENT OF INDEPENDENT AUDITOR

General Information

The Audit Committee has exclusive authority with respect to the appointment, compensation, retention, and oversight of the independent auditor employed by the Company. In performing these responsibilities, among other things, the Audit Committee (i) reviews the qualifications, performance, and independence of the independent auditor, (ii) reviews and evaluates the lead partner of the independent auditor having primary responsibility for the Company’s audit, and (iii) considers whether the accounting firm chosen as the independent auditor should be rotated in order to maintain the independence between the independent auditor and the Company.

The Audit Committee has appointed Ernst & Young LLP (“EY”), an independent registered public accounting firm (the “independent auditor”), to audit the Company’s financial statements for fiscal year 2020. EY served as the Company’s independent auditor for fiscal year 2019 and reported on the Company’s consolidated financial statements for that year. EY has served as the Company’s independent auditor since 2018. The Board believes that the continued retention of EY to serve as the Company’s independent auditor is in the best interests of the Company and its stockholders and, at the request of the Audit Committee, is asking its stockholders to ratify such appointment.

Representatives of EY will be present at the annual meeting and will have an opportunity to make a statement, if they desire to do so, and to respond to appropriate questions regarding the Company’s business.

Although stockholder ratification is not required, the appointment of EY as the Company’s independent auditor for fiscal year 2020 is being submitted for ratification at the annual meeting because the Board believes doing so is a good corporate governance practice. Furthermore, the Audit Committee will take stockholders’ opinions regarding the appointment of EY into consideration in future deliberations. If EY’s appointment is not ratified at the annual meeting, the Audit Committee will consider the engagement of other independent auditors. The Audit Committee may terminate EY’s engagement as the Company’s independent auditor without the approval of the Company’s stockholders whenever the Audit Committee deems appropriate.

Information Regarding Prior Independent Auditor

On December 17, 2018, the Board, upon the recommendation of the Audit Committee, unanimously resolved (i) to dismiss WithumSmith+Brown, PC (“Withum”) as the Company’s independent auditor and (ii) to engage EY to serve as the Company’s independent auditor for the fiscal year ending December 31, 2018. This decision followed the consummation of the Company’s initial business combination on November 9, 2018.

The audit report of Withum on the consolidated financial statements of the Company as of and for the fiscal year ended December 31, 2017 did not contain any adverse opinion or disclaimer of opinion, nor was it qualified or modified as to uncertainty, audit scope, or accounting principles.

During the period from January 1 through December 19, 2018, there were no disagreements between the Company and Withum on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to Withum’s satisfaction, would have caused Withum to make reference to the subject matter of the disagreements in connection with their report, and there were no reportable events as described in Item 304(a)(1)(v) of Regulation S-K under the Exchange Act.

The Company previously provided Withum with a copy of disclosures consistent with the information above. A letter dated December 19, 2018, from Withum stating its agreement with such statements is listed under Item 9 as Exhibit 16.1 and is incorporated by reference in the Company’s Current Report on Form 8-K filed with the SEC on December 19, 2018.

32

During the period from January 1 through December 19, 2018, the Company did not consult EY with respect to (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements, and no written report or oral advice was provided to the Company by EY that EY concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing, or financial reporting issue, or (ii) any matter that was either the subject of a disagreement, as that term is described in Item 304(a)(1)(iv) of Regulation S-K under the Exchange Act and the related instructions thereto, or a reportable event, as that term is described in Item 304(a)(1)(v) of Regulation S-K under the Exchange Act.

Fees Paid for 2019 and 2018

The fees paid to the Company’s independent auditors for 2019 and 2018 were as follows:

Description	2019 ($)		2018 ($)
Audit Fees (1)		1,513,452		680,500
Audit-Related Fees (2)		—		8,000
Tax Fees (3)		—		3,000
All Other Fees		—		—

(1) Audit Fees were for professional services rendered for the annual audit of the Company’s consolidated financial statements included in the Form 10-K, the reviews of the Company’s financial statements included in the Forms 10-Q, and other procedures required to be performed by the independent auditor to be able to form an opinion on the Company’s consolidated financial statements. The Audit Fees for 2019 include EY’s annual audit of the Company’s consolidated financial statements for the 2019 fiscal year, the reviews of the financial statements included in the Forms 10-Q, and assistance with and review of documents filed with the SEC. The Audit Fees for 2019 were higher as a result of increased activity associated with the Company’s equity method interests in four pipeline joint ventures, the issuance of preferred units, and long-lived asset impairments. The Audit Fees for 2018 include $585,000 for the engagement of EY’s annual audit of the Company’s consolidated financial statements for the 2018 fiscal year and $95,500 for services provided by Withum for the 2018 fiscal year prior to their dismissal as discussed in the section above.

(2) Audit-Related Fees were for assurance and related services that are reasonably related to the performance of the audit or review of the Company’s financial statements or that are traditionally performed by the independent auditor and do not include amounts reported under Audit Fees. Audit-related services include consultations related to accounting, financial reporting, or disclosure matters not classified as “audit services” and agreed-upon or expanded audit procedures. All Audit-Related Fees in 2018 were associated with services provided by Withum.

(3) Tax Fees were for professional services related to tax planning and compliance, tax-related and structuring-related consultation, and tax services related to potential acquisitions or dispositions. All Tax Fees in 2018 were associated with services provided by Withum.

All audit, audit-related, tax, and other services were pre-approved by the Audit Committee, which concluded that the provision of such services by EY or Withum, as applicable, was compatible with that firm’s independence in the conduct of its auditing functions. The Audit Committee has taken into consideration whether the provision of non-audit services by EY or Withum, as applicable, is compatible with maintaining auditor independence.

None of the services described above were approved pursuant to the de minimis exception provided in Rule 2-01(c)(7)(i)(C) of Regulation S-X promulgated by the SEC.

Pre-Approval of Independent Auditor Services and Fees

To ensure the independence of our independent auditor and to comply with the applicable securities laws, the listing standards of the Nasdaq, and the Audit Committee charter, the Audit Committee has established a policy

33

and related procedures with respect to services that may be performed by the Company’s independent auditor (the “Pre-Approval Policy”).

The Pre-Approval Policy provides that the Company’s independent auditor may not perform any service for the Company, subject to those exceptions that may be permitted by applicable law, unless (i) the service has been pre-approved by the Audit Committee or (ii) the Company engaged the independent auditor to perform the service pursuant to the pre-approval provisions of the Pre-Approval Policy. In addition, the Pre-Approval Policy prohibits the Audit Committee from pre-approving certain non-audit services that are prohibited from being performed by the Company’s independent auditor by applicable securities laws.

Pursuant to the Pre-Approval Policy, the Audit Committee has pre-approved certain categories of services to be performed by the independent auditor and a maximum amount of fees for each category. The Audit Committee reassesses these service categories and the associated maximum fee limits annually. Individual projects within the approved service categories have been pre-approved only to the extent that the fees for each individual project do not exceed a specified dollar limit, which amount is reassessed annually. The Committee also considers on a case-by-case basis specific engagements that are not otherwise pre-approved or that exceed pre-approved fee amounts. The Audit Committee grants pre-approval, subject to fee limits, for services that fall within the “All Other Fees” category on an engagement-by-engagement basis.

The Audit Committee has delegated to the chair of the Audit Committee its pre-approval responsibilities. The chair has the authority to approve interim requests to pre-approve services and maximum fee limits, provided that the chair informs the Audit Committee of any such decisions at the Audit Committee’s next scheduled meeting.

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” RATIFICATION OF THE APPOINTMENT OF EY AS THE COMPANY’S INDEPENDENT AUDITOR FOR FISCAL YEAR 2020.

PROPOSAL 3. APPROVAL OF THE SHARE ISSUANCE PROPOSAL

General Information

The Company’s Class A Common Stock is listed on the Nasdaq, and we are subject to the Nasdaq listing rules. Nasdaq Marketplace Rule 5635(d) (the “Nasdaq 20% Rule”) requires stockholder approval prior to the issuance of securities in connection with transactions, other than public offerings, where the common stock to be issued equals 20% or more of the common stock or 20% or more of the voting power outstanding before the issuance. In accordance with the Nasdaq 20% Rule, the Company’s stockholders are being asked to approve the issuance of a number of shares of the Company’s Class A Common Stock upon the potential exchange of certain preferred units issued by one of our subsidiaries, which, if exercised, may result in the issuance by the Company of more than 20% of the Company’s outstanding Class A Common Stock. This proposal is referred to as the “Share Issuance Proposal.”

Background

On May 8, 2019, the Company’s subsidiary, Altus Midstream LP, a Delaware limited partnership (the “Partnership”), and the Company entered into a Preferred Unit Purchase Agreement (the “Purchase Agreement”) among the Partnership, the Company, and the purchasers party thereto (the “Purchasers”) to provide for the sale by the Partnership to the Purchasers of $625 million in aggregate issue price of the Partnership’s Series A Cumulative Redeemable Preferred Units (the “Preferred Units”) in a private offering exempt from the registration requirements of the Securities Act pursuant to Section 4(a)(2) thereof. On June 12, 2019, a total of 625,000 Preferred Units were issued and sold at a price of $1,000 per Preferred Unit (the “Closing”). Pursuant to the Purchase Agreement, the Company agreed to submit this Share Issuance Proposal to obtain stockholder approval of the potential exchange of the Preferred Units into a number of shares of Class A Common Stock.

In connection with the Closing, Apache, the Company, and certain Purchasers of the Preferred Units entered into a voting agreement (the “Voting Agreement”), pursuant to which Apache has agreed to vote all shares of the Company’s common stock over which Apache has beneficial ownership in favor of the Share Issuance Proposal. At the Closing, the partners of the Partnership entered into the Second Amended and Restated Agreement of Limited Partnership of Altus Midstream (the “Amended LPA”), which sets forth the terms of the Preferred Units.

Description of the Preferred Unit Exchange Right

The Preferred Units will be exchangeable for shares of the Company’s Class A Common Stock at the option of the Preferred Unit holders after the seventh anniversary of Closing or upon the occurrence of specified events. Each Preferred Unit will be exchangeable for a number of shares of Class A Common Stock equal to the Redemption Price divided by the volume-weighted average trading price of the Class A Common Stock on the Nasdaq for the 20 trading days immediately preceding the second trading day prior to the applicable exchange date, less a 6% discount. The “Redemption Price” is equal to (a) the greater of (i) an 11.5% internal rate of return (increasing to 13.75% after the fifth anniversary of Closing), and (ii) a 1.3x multiple of invested capital plus (b) if applicable, the value of any accrued and unpaid distributions.

Effect of Failure to Obtain Stockholder Approval

If the stockholders do not approve the Share Issuance Proposal, the Company has agreed to submit the terms of the Share Issuance Proposal to the stockholders at the subsequent annual or a special meeting. Unless the Share Issuance Proposal is approved, the Preferred Units will not be exchangeable into more than 19.5% of the outstanding voting power of the Company.

We are not seeking stockholder approval to authorize the offering of the Preferred Units, the entry into or the Closing of the transaction, or the execution of the related transaction documents, including the Purchase Agreement, the Voting Agreement, or the Amended LPA, as we have already entered into and closed the

35

transaction and executed the related transaction documents, which are binding obligations on the Partnership and the Company. If the Share Issuance Proposal is not approved by our stockholders, it will not negate the existing terms of such documents or any other documents relating to the transaction.

Effect of Stockholder Approval

If the stockholders approve the Share Issuance Proposal, the Preferred Units may be exchanged into a number of shares of Class A Common Stock pursuant to their terms as summarized above. The exchange, if exercised, would result in an increase in the number of shares of Class A Common Stock outstanding and dilution of current equity ownership of the Company held by stockholders who are not also holders of Preferred Units. Such stockholders would have reduced voting power, liquidation value, and book value of the Company and therefore have less ability to influence corporate decisions requiring stockholder approval. Dilution of equity interests would reduce such stockholders’ interests in the Company’s future earnings and could also cause prevailing market prices for our Class A Common Stock to decline.

Because the timing and price may vary at which shares of Class A Common Stock may be issued in exchange for the Preferred Units and because of the number of shares to be issued is dependent upon the share price, the exact magnitude of the dilutive effect of the potential exchange cannot be determined. However, the dilutive effect may be material to current stockholders of the Company.

Additional Information Regarding the Preferred Units

The Amended LPA provides the terms of the Preferred Units, including the distribution rate, redemption rights, and rights to exchange the Preferred Units for shares of the Company’s Class A Common Stock, as well as rights of holders of the Preferred Units to approve certain Partnership business and financial and governance-related matters.

The material terms of the Preferred Units, including copies of the Purchase Agreement and the Amended LPA, can be found in the Company’s Current Reports on Form 8-K filed with the SEC on May 13, 2019 and June 14, 2019.

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” APPROVAL OF THE SHARE ISSUANCE PROPOSAL.

PROPOSAL 4. APPROVAL OF THE REVERSE STOCK SPLIT PROPOSAL

General Information

The Board has unanimously approved a reverse stock split of all outstanding shares of the Company’s common stock, by a ratio of one-for-twenty (the “Reverse Stock Split”). At the annual meeting, the Board is asking the Company’s stockholders to approve an amendment to the Company’s Second Amended and Restated Certificate of Incorporation (the “Amendment”) to effect the Reverse Stock Split (the “Reverse Stock Split Proposal”). The full text of the Amendment is attached to this proxy statement as Appendix A.

The Reverse Stock Split Proposal provides that the Board shall have sole discretion pursuant to Section 242(c) of the Delaware General Corporation Law (the “DGCL”) to elect, as it determines to be in the best interests of the Company and its stockholders, for the purpose of maintaining the listing of the Company’s Class A Common Stock on the Nasdaq, whether or not to effect the Reverse Stock Split on or before December 31, 2020. In determining whether to implement the Reverse Stock Split following the receipt of stockholder approval of the Reverse Stock Split Proposal, the Board may consider, among other things, factors such as:

• the historical trading price and trading volume of the Class A Common Stock;

• the then prevailing trading price and trading volume of the Class A Common Stock and the anticipated impact of the Reverse Stock Split on the Class A Common Stock;

• the trading market for the Class A Common Stock;

• the Company’s ability to maintain listing of the Class A Common Stock on the Nasdaq;

• the anticipated impact of the Reverse Stock Split on the Company’s ability to raise additional financing; and

• prevailing general market and economic conditions.

If the Reverse Stock Split Proposal is approved by the Company’s stockholders at the annual meeting and the Board determines, in its sole discretion, that effecting the Reverse Stock Split is necessary to maintain the listing of the Class A Common Stock on the Nasdaq and is also in the best interests of the Company and its stockholders, then the Reverse Stock Split will become effective as of 5:30 p.m. Eastern Time on the date that the Amendment is filed with the Secretary of State of the State of Delaware (the “Effective Date”). Except as explained below with respect to fractional shares, each issued share of common stock outstanding immediately prior to the Effective Date will automatically be changed, as of the Effective Date, into a fraction of a share of common stock based on the one-for-twenty reverse stock split ratio.

All holders of the Company’s common stock will be affected proportionally by the Reverse Stock Split. Except for adjustments that may result from the treatment of fractional shares as described below, each stockholder will hold the same percentage of our outstanding common stock immediately following the Reverse Stock Split as such stockholder holds immediately prior to the Reverse Stock Split.

As of February 29, 2020, there were 324,929,305 shares of the Company’s common stock issued and outstanding, including 74,929,305 shares of Class A Common Stock and 250,000,000 shares of Class C Common Stock. Based on such number of shares of common stock issued and outstanding, immediately following the Reverse Stock Split (and without giving any effect to fractional shares), the Company would have 16,246,465 shares of common stock issued and outstanding, including 3,746,465 shares of Class A Common Stock and 12,500,000 shares of Class C Common Stock.

The Board believes that approval of the Amendment to effect the Reverse Stock Split is in the best interests of the Company and its stockholders and has unanimously recommended that the Reverse Stock Split Proposal be presented to the Company’s stockholders for approval at the annual meeting.

37

Board Discretion to Implement the Reverse Stock Split

The Reverse Stock Split will be effected, if at all, only upon a determination by the Board that the Reverse Stock Split is necessary to maintain the listing of the Class A Common Stock on the Nasdaq and is also in the best interests of the Company and its stockholders. Such determination shall be based upon certain factors, including, but not limited to, the historical trading price and trading volume of the Class A Common Stock; the then prevailing trading price and trading volume of the Class A Common Stock and the anticipated impact of the Reverse Stock Split on the trading market for the Class A Common Stock; the Company’s ability to maintain listing of the Class A Common Stock on the Nasdaq; the anticipated impact of the Reverse Stock Split on the Company’s ability to raise additional financing; and prevailing general market and economic conditions. No further action on the part of the Company’s stockholders would be required to either implement or not implement the Reverse Stock Split.

If the Reverse Stock Split Proposal is approved by the Company’s stockholders, but the Effective Date of the Reverse Stock Split does not occur on or prior to December 31, 2020, then the Board’s authority to implement the Reverse Stock Split will terminate. The Board’s principal purpose for authorizing the Reverse Stock Split is to keep the Class A Common Stock listed for trading on the Nasdaq. As such, the Board reserves its right to elect not to proceed with the Reverse Stock Split if it determines, in its sole discretion, that the Reverse Stock Split is no longer necessary to maintain the listing of the Class A Common Stock on the Nasdaq or is no longer in the best interests of the Company or its stockholders.

Reasons for the Reverse Stock Split

The Board unanimously approved the Reverse Stock Split Proposal because it believes that effecting the Reverse Stock Split may be an effective means of maintaining compliance with Nasdaq’s continued listing requirements for the Company’s Class A Common Stock. In the event that the Board, in its sole discretion determines to implement the Reverse Stock Split for such purpose, the Board believes that the Reverse Stock Split could also improve the marketability and liquidity of the Class A Common Stock.

Maintaining listing of the Class A Common Stock on the Nasdaq. In order for the Company’s Class A Common Stock to remain listed for trading on the Nasdaq, the Company is required to comply with the Nasdaq’s continued listing requirements, including that the Class A Common Stock maintain a minimum bid price of $1.00 per share (the “Minimum Bid Price Requirement”). On March 31, 2020, the closing price of the Company’s Class A Common Stock, as reported by Nasdaq, was $0.75 per share and had been below the $1.00 Minimum Bid Price Requirement for ten consecutive business days. If the Class A Common Stock were to remain below the Minimum Bid Price Requirement for 30 consecutive business days, then Nasdaq would send a deficiency notice to the Company, advising the Company that it has 180 calendar days to regain compliance with the Minimum Bid Price Requirement. If the Company were unable to regain compliance during the allotted compliance period, subject to certain extensions, then the Class A Common Stock would be subject to delisting by the Nasdaq.

The Board has considered the potential harm to the Company and its stockholders should the Nasdaq delist the Class A Common Stock. Delisting the Class A Common Stock could adversely affect the liquidity of the Class A Common Stock because alternatives, such as the OTC Bulletin Board and the pink sheets, are generally considered to be less efficient markets. An investor likely would find it less convenient to sell, or to obtain accurate quotations in seeking to buy, the Class A Common Stock on an over-the-counter market. Many investors likely would not buy or sell the Class A Common Stock due to difficulty in accessing over-the-counter markets, policies preventing them from trading in securities not listed on a national exchange, or other reasons.

The Board believes that the Reverse Stock Split is a potentially effective means for the Company to maintain compliance with the Nasdaq continued listing requirements and to avoid the potentially adverse consequences of the Class A Common Stock being delisted from the Nasdaq by producing the immediate effect of increasing the bid price of the Class A Common Stock.

38

Improving the marketability and liquidity of the Class A Common Stock. If the Reverse Stock Split Proposal is approved by the Company’s stockholders at the annual meeting and the Board determines to effect the Reverse Stock Split in order to avoid delisting of the Class A Common Stock from the Nasdaq, then the Board also believes that the increased market price of the Class A Common Stock expected as a result of implementing the Reverse Stock Split will improve the marketability and liquidity of the Class A Common Stock and will encourage interest and trading in the Class A Common Stock.

The Board believes that a higher stock price may help to maintain investor interest in the Company, including interest among institutional investors (including funds that are prohibited from buying stocks whose price is below a certain threshold). Because of the trading volatility often associated with low-priced stocks, many brokerage houses and institutional investors have internal policies and practices that either prohibit them from investing in low-priced stocks or tend to discourage individual brokers from recommending low-priced stocks to their customers. Some of those policies and practices may function to make the processing of trades in low-priced stocks economically unattractive to brokers. Additionally, because brokers’ commissions on low-priced stocks generally represent a higher percentage of the stock price than commissions on higher-priced stocks, the current average price per share of the Class A Common Stock can result in individual stockholders paying transaction costs representing a higher percentage of their total share value than would be the case if the share price were substantially higher.

If the Reverse Stock Split successfully increases the price per share of the Company’s Class A Common Stock and facilitates the continued listing of the Class A Common Stock on the Nasdaq, then the Board believes this increase may also help the Company to facilitate future financings, enhance the Company’s ability to engage in transactions using or that involve the Company’s Class A Common Stock, and increase the appetite of third parties with whom the Company may negotiate for purposes of evaluating potential strategic alternatives.

For the above reasons, the Board believes that the Reverse Stock Split will help the Company regain and maintain compliance with the Nasdaq continued listing requirements and may also improve the marketability and liquidity of the Class A Common Stock, and as such, the Board believes that the Reverse Stock Split is in the best interests of the Company and its stockholders.

Certain Risks Associated with the Reverse Stock Split

The Reverse Stock Split may not increase the market price of the Class A Common Stock.

The Board expects that the Reverse Stock Split will increase the market price of the Class A Common Stock so that the Company is able to regain and maintain compliance with the Nasdaq’s Minimum Bid Price Requirement. However, the effect of the Reverse Stock Split upon the market price of the Class A Common Stock cannot be predicted with any certainty, and the history of similar reverse stock splits for companies in like circumstances is varied. Accordingly, there is no assurance that the Company will be able to maintain listing of the Class A Common Stock on the Nasdaq after the Reverse Stock Split is effected or that the market price per share of the Class A Common Stock after the Reverse Stock Split will exceed or remain in excess of the $1.00 Minimum Bid Price Requirement for a sustained period of time.

It is possible that the per share price of the Class A Common Stock after the Reverse Stock Split will not rise in proportion to the reduction in the number of shares of the Class A Common Stock outstanding resulting from the Reverse Stock Split, and there is no assurance that the Reverse Stock Split will lead to a sustained increase in the trading price of the Company’s Class A Common Stock. The market price per post-Reverse Stock Split share may not exceed or remain in excess of the $1.00 Minimum Bid Price Requirement for a sustained period of time. Even if the Reverse Stock Split is effected, the market price of the Class A Common Stock may decrease due to factors unrelated to the Reverse Stock Split, including the Company’s ability to successfully accomplish its business goals, market conditions, and the market perception of the Company’s business.

Stockholders should also keep in mind that the implementation of the Reverse Stock Split does not have an effect on the actual or intrinsic value of the Company’s business or a stockholder’s proportional ownership in the

39

Company. However, should the overall value of the Class A Common Stock decline after the proposed Reverse Stock Split, then the actual or intrinsic value of the shares of Class A Common Stock held by each of the Company’s stockholders will also proportionately decrease as a result of the overall decline in value.

There can be no assurance that the total market capitalization of the Company’s Class A Common Stock after the implementation of the Reverse Stock Split will be equal to or greater than the total market capitalization before the Reverse Stock Split. If the Reverse Stock Split is consummated and the trading price of the Common Stock declines, the percentage decline as an absolute number and as a percentage of our overall market capitalization may be greater than would occur in the absence of the Reverse Stock Split. Additionally, even if the market price per post-Reverse Stock Split share of the Class A Common Stock remains in excess of $1.00 per share, we may be delisted due to a failure to meet other continued listing requirements, including Nasdaq requirements related to the minimum stockholders’ equity, the minimum number of shares that must be in the public float, the minimum market value of the public float, and the minimum number of round lot holders.

The Reverse Stock Split may decrease the liquidity of the Class A Common Stock.

The liquidity of the Class A Common Stock may be harmed by the proposed Reverse Stock Split given the reduced number of shares of Common Stock that would be outstanding after the Reverse Stock Split, particularly if the stock price does not increase as a result of the Reverse Stock Split. In addition, investors might consider the increased proportion of unissued authorized shares of common stock to issued shares to have an anti-takeover effect under certain circumstances, because the proportion allows for dilutive issuances which could prevent certain stockholders from changing the composition of the Board or render tender offers for a combination with another entity more difficult to successfully complete. The Board does not intend for the Reverse Stock Split to have any anti-takeover effects.

Principal Effects of the Reverse Stock Split

Effect on the Company’s Common Stock. If the Reverse Stock Split Proposal is approved by the stockholders at the annual meeting and the Board determines to effect the Reverse Stock Split, then the Company will file an Amendment to the Second Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware. Except for adjustments that may result from the treatment of fractional shares as described below, each issued share of common stock outstanding immediately prior to the Effective Date will automatically be changed, as of the Effective Date, into a fraction of a share of Common Stock based on the one-for-twenty reverse stock split ratio. As a result, each stockholder will own a reduced number of shares of common stock. The principal effect of the Reverse Stock Split will be to proportionately decrease the number of outstanding shares of the Company’s outstanding common stock based on the one-for-twenty reverse stock split ratio.

Except for adjustments that may result from the treatment of fractional shares of Common Stock as described below, because the Reverse Stock Split will apply to all issued and outstanding shares of our Common Stock, the Reverse Stock Split will not alter the relative rights and preferences of our existing stockholders nor affect any stockholder’s proportionate equity interest in the Company. For example, a holder of two percent (2%) of the voting power of the outstanding shares of the Company’s common stock immediately prior to the effectiveness of the Reverse Stock Split will generally continue to hold two percent (2%) of the voting power of the outstanding shares of the Company’s common stock immediately after the Reverse Stock Split. Moreover, the number of stockholders of record will not be affected by the Reverse Stock Split.

While the Amendment to the Second Amended and Restated Certificate of Incorporation will not change the number of authorized shares of the Company’s common stock, the Reverse Stock Split will have the effect of creating additional unreserved shares of the Company’s authorized common stock. Although at present the Company has no current arrangements or understandings providing for the issuance of the additional shares of common stock that would be made available for issuance upon effectiveness of the Reverse Stock Split, other than as described in the Share Issuance Proposal above, such additional shares may be used by the Company for various purposes in the future without further stockholder approval.

40

Effect on the Company’s Warrants. As of February 29, 2020, the Company had 18,941,631 warrants outstanding. Each warrant entitles the holder to purchase one share of the Company’s Class A Common Stock at a price of $11.50 per share. If the Reverse Stock Split Proposal is approved by the Company’s stockholders and effected by the Board, then proportional adjustments will be made to the number of shares of Class A Common Stock issuable under, and the exercise price of, the outstanding warrants.

Effect on Altus Midstream LP’s Common Units and Series A Cumulative Redeemable Preferred Units. Pursuant to the Second Amended and Restated Agreement of Limited Partnership of Altus Midstream LP (“Altus Midstream”), the Company cannot effect the Reverse Stock Split unless Altus Midstream’s outstanding common units (the “Common Units”) are combined on an identical basis, with corresponding changes made with respect to any other exchangeable or convertible securities, including Altus Midstream’s Series A Cumulative Redeemable Preferred Units (the “Preferred Units”). As of February 29, 2020, Altus Midstream had issued and outstanding 324,929,305 Common Units and 625,000 Preferred Units. Apache has the ability to redeem or exchange its 250,000,000 Common Units for shares of the Company’s Class A Common Stock on a one-for-one basis, subject to adjustments, provided that the Company has the ability to settle such redemption in cash. The Preferred Units will be exchangeable for shares of the Company’s Class A Common Stock at the option of the Preferred Unit holders after the seventh anniversary of the closing of the Preferred Unit offering or upon the occurrence of specified events. The number of shares of Class A Common Stock issued in any exchange would be based on the then-current trading price of the Class A Common Stock. In accordance with the terms of the Second Amended and Restated Agreement of Limited Partnership of Altus Midstream, if the Reverse Stock Split Proposal is approved by the Company’s stockholders and effected by the Board, then proportional adjustments will be made to Altus Midstream’s outstanding Common Units.

Effect on the Company’s Equity Compensation Plans. Pursuant to the terms of the Company’s 2019 Omnibus Compensation Plan and Restricted Stock Units Plan (collectively, the “Plans”), if the Reverse Stock Split Proposal is approved by the Company’s stockholders and effected by the Board, then the Board or a committee thereof, as applicable, will adjust the number of shares of Common Stock or restricted stock units available for future grant under the Plans, the number of shares of Common Stock or restricted stock units underlying outstanding awards, the exercise price, grant price or purchase price applicable to any award, and other terms of outstanding awards issued pursuant to the Plans to equitably reflect the effects of the Reverse Stock Split.

Listing. The Class A Common Stock is currently listed for trading on the Nasdaq Global Select Market under the symbol “ALTM.” The Reverse Stock Split will not directly affect the listing of the Class A Common Stock on the Nasdaq, although the Board believes that the Reverse Stock Split could potentially increase the price of the Class A Common Stock, thereby facilitating compliance with the Nasdaq’s Minimum Bid Price Requirement. Following the Reverse Stock Split, the Class A Common Stock will continue to be listed on the Nasdaq Global Select Market under the symbol “ALTM,” but as of the Effective Date of the Reverse Stock Split, the Class A Common Stock will have a new committee on uniform securities identification procedures (“CUSIP”) number, which is a number used to identify the Class A Common Stock.

“Public Company” Status. The Class A Common Stock is currently registered under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the Company is subject to the “public company” periodic reporting and other requirements of the Exchange Act. The Reverse Stock Split will not affect the Company’s status as a public company or the registration of the Class A Common Stock under the Exchange Act. The Reverse Stock Split is not intended as, and will not have the effect of, a “going private transaction” covered by Rule 13e-3 under the Exchange Act.

Odd Lot Transactions. It is likely that some of the Company’s stockholders will own “odd-lots” of less than 100 shares of Class A Common Stock following the Reverse Stock Split. A purchase or sale of less than 100 shares of Class A Common Stock (an “odd lot” transaction) may result in incrementally higher trading costs through certain brokers, particularly “full service” brokers, and generally may be more difficult than a “round lot” sale. Therefore, those stockholders who own less than 100 shares of Class A Common Stock following the Reverse

41

Stock Split may be required to pay somewhat higher transaction costs and may experience some difficulties or delays should they then determine to sell their shares of Class A Common Stock.

Authorized but Unissued Shares; Potential Anti-Takeover Effects. The Company’s Second Amended and Restated Certificate of Incorporation presently authorizes the Company to issue 3,000,000,000 shares of common stock, including 1,500,000,000 shares of Class A Common Stock and 1,500,000,000 shares of Class C Common Stock, and 50,000,000 shares of preferred stock. The Reverse Stock Split will not change the number of authorized shares of common stock or preferred stock as designated. Therefore, because the number of issued and outstanding shares of common stock will decrease, the number of shares of common stock remaining available for issuance by us in the future will increase.

Such additional shares will be available for issuance from time to time for corporate purposes such as issuances of Class A Common Stock in connection with capital-raising transactions and acquisitions of companies or other assets, as well as for issuance upon conversion or exercise of securities such as the warrants and Preferred Units. The Board believes that the availability of the additional shares of common stock will provide the Company with the flexibility to meet business needs as they arise, to take advantage of favorable opportunities and to respond effectively in a changing corporate environment. For example, the Company may elect to issue shares of Class A Common Stock to raise equity capital, to make acquisitions through the use of stock, to establish strategic relationships with other companies, to adopt additional employee benefit plans or reserve additional shares of Common Stock for issuance under such plans, where the Board determines it advisable to do so, without the necessity of soliciting further stockholder approval, subject to applicable stockholder vote requirements under the DGCL and the Nasdaq listing rules. If we issue additional shares of common stock for any of these purposes, the aggregate ownership interest of our current stockholders, and the interest of each such existing stockholder, will be diluted, possibly substantially.

The additional shares of common stock that will become available for issuance upon an effective Reverse Stock Split could also be used by us to oppose a hostile takeover attempt or delay or prevent a change of control or changes in or removal of our management, including any transaction that may be favored by our stockholders or in which our stockholders might otherwise receive a premium for their shares of common stock over then-current market prices or benefit in some other manner. Although the increased proportion of authorized but unissued shares of common stock to issued shares of common stock could, under certain circumstances, have an anti-takeover effect, the Reverse Stock Split is not being proposed in order to respond to a hostile takeover attempt or to an attempt to obtain control of the Company.

Fractional Shares

No fractional shares will be issued in connection with the Reverse Stock Split. Each stockholder that otherwise would be entitled to receive a fractional share as a result of the Reverse Stock Split will be entitled to receive, upon surrender to the exchange agent of certificates representing such pre-Reverse Stock Split shares, if applicable, payment of cash in lieu of such fractional share. Such cash payment in lieu of a fractional share will be calculated by multiplying such fractional interest in one share of the Company’s common stock by the volume-weighted average trading price of the Class A Common Stock on the Nasdaq for the twenty consecutive trading days ending on the trading day immediately preceding the Effective Date (as adjusted to give effect to the Reverse Stock Split). After the Reverse Stock Split, a stockholder otherwise entitled to a fractional share of the Company’s common stock will not have any voting, dividend, or other rights with respect to such fractional share except to receive payment as described above. Stockholders will not be entitled to receive interest for the period of time between the Effective Date and the date payment is made for their fractional share interest.

At the Effective Date, stockholders owning, prior to the Reverse Stock Split, less than twenty whole shares of the Company’s common stock will no longer be stockholders of the Company. For example, if a stockholder held ten shares of Class A Common Stock immediately prior to the Reverse Stock Split, then based on the one-for-twenty reverse stock split ratio, such stockholder would cease to be a stockholder of the Company following the Reverse Stock Split and would not have any voting, dividend, or other rights except the right to receive payment for the

42

fractional share as described above. Shares of the Company’s common stock held in registered form and shares of the Company’s common stock held in “street name” (that is, through a broker, bank, or other holder of record) for the same stockholder will be considered held in separate accounts and will not be aggregated when effecting the Reverse Stock Split.

On February 29, 2020, there were 115 holders of record of the Company’s Class A Common Stock and one holder of the Company’s Class C Common Stock. Based on the one-for-twenty reverse stock split ratio, the Company does not expect that cashing out fractional stockholders will reduce the number of holders of record of the Company’s common stock.

Shares Held in Book-Entry

Stockholders who hold registered shares of the Company’s common stock in a book-entry form do not need to take any action to receive their post-Reverse Stock Split shares of the Company’s common stock in registered book-entry form. If you are entitled to post-Reverse Stock Split shares of the Company’s common stock, then a transaction statement will automatically be sent to your address of record by the Company’s transfer agent as soon as practicable after the Effective Date indicating the number of shares of the Company’s common stock you hold. In addition, if you are entitled to a payment of cash in lieu of fractional shares, a check will be mailed to you at your registered address as soon as practicable after the Effective Date. By signing and cashing that check, you will warrant that you owned the shares of the Company’s common stock for which you received a cash payment.

As of the Effective Date, the Company intends to treat stockholders holding shares of the Company’s common stock in “street name” (that is, through a broker, bank, or other holder of record) in the same manner as registered stockholders whose shares of the Company’s common stock are registered in their names. Brokers, banks, or other holders of record will be instructed to effect the Reverse Stock Split for their beneficial holders holding shares of the Company’s common stock in “street name.” However, such brokers, banks or other holders of record may apply their own specific procedures for processing the Reverse Stock Split. If you hold your shares of our common stock with a broker, bank, or other holder of record, and you have any questions in this regard, the Company encourages you to contact your holder of record.

Exchange of Stock Certificates

Certain stockholders may hold some or all of their shares of the Company’s common stock in certificated form. As of the Effective Date, each certificate representing shares of the Company’s common stock outstanding before the Reverse Stock Split will be deemed, for all corporate purposes, to evidence ownership of the reduced number of shares of the Company’s common stock resulting from the Reverse Stock Split.

The Company’s transfer agent, American Stock Transfer & Trust Company, LLC, will act as the exchange agent for purposes of exchanging stock certificates subsequent to the Reverse Stock Split. Shortly after the Effective Date, stockholders of record that hold shares in certificated form will receive written instructions requesting them to complete and return a letter of transmittal and surrender their old stock certificates for new stock certificates reflecting the adjusted number of shares as a result of the Reverse Stock Split and payment in lieu of fractional shares (if any). Certificates representing shares of the Company’s common stock issued in connection with the Reverse Stock Split will continue to bear the same restrictive legends, if any, that were borne by the surrendered certificates representing the shares of the Company’s common stock outstanding prior to the Reverse Stock Split. No new certificates will be issued until such stockholder has surrendered any outstanding certificates, together with the properly completed and executed letter of transmittal, to the exchange agent. Until surrendered, each certificate representing shares of the Company’s common stock outstanding before the Reverse Stock Split will continue to be valid and will represent the adjusted number of shares of the Company’s common stock, based on the one-for-twenty reverse stock split ratio.

Any stockholder whose stock certificates are lost, destroyed, or stolen will be entitled to a new certificate or certificates representing post-Reverse Stock Split shares of the Company’s common stock upon compliance with

43

the requirements that the Company and the Company’s transfer agent customarily apply in connection with lost, destroyed, or stolen certificates. Instructions as to lost, destroyed, or stolen certificates will be included in the letter of instructions from the exchange agent.

YOU SHOULD NOT DESTROY YOUR STOCK CERTIFICATES, AND YOU SHOULD NOT SEND THEM NOW. YOU SHOULD SEND YOUR STOCK CERTIFICATES ONLY AFTER YOU HAVE RECEIVED INSTRUCTIONS FROM THE EXCHANGE AGENT AND IN ACCORDANCE WITH THOSE INSTRUCTIONS.

If any certificates for shares of the Company’s common stock are to be issued in a name other than that in which the certificates for shares of the Company’s common stock surrendered are registered, the stockholder requesting the reissuance will be required to pay to us any transfer taxes or establish to our satisfaction that such taxes have been paid or are not payable and, in addition, (a) the transfer must comply with all applicable federal and state securities laws, and (b) the surrendered certificate must be properly endorsed and otherwise be in proper form for transfer.

No Dissenters’ Rights

Under Delaware law, the Company’s stockholders would not be entitled to dissenters’ rights or rights of appraisal in connection with the implementation of the Reverse Stock Split, and the Company will not independently provide our stockholders with any such rights.

Certain U.S. Federal Income Tax Consequences of the Reverse Stock Split

The following is a summary of certain United States federal income tax consequences of the Reverse Stock Split. It does not address any state, local, or foreign income or other tax consequences, which, depending upon the jurisdiction and the status of the stockholder/taxpayer, may vary from the United States federal income tax consequences. It applies to you only if you held pre-Reverse Stock Split shares of common stock as capital assets for United States federal income tax purposes. This discussion does not apply to you if you are a member of a class of our stockholders subject to special rules, such as a (a) dealer in securities or currencies, (b) trader in securities that elects to use a mark-to-market method of accounting for your securities holdings, (c) bank, (d) life insurance company, (e) tax-exempt organization, (f) person that owns shares of common stock that are a hedge, or that are hedged, against interest rate risks, (g) person who owns shares of common stock as part of a straddle or conversion transaction for tax purposes, or (h) person whose functional currency for tax purposes is not the U.S. dollar. The discussion is based on the Internal Revenue Code of 1986, as amended (the “Code”), its legislative history, existing, temporary, and proposed regulations under the Code, published rulings, and court decisions, all as of the date hereof. These laws, regulations, and other guidance are subject to change, possibly on a retroactive basis. We have not sought and will not seek an opinion of counsel or a ruling from the Internal Revenue Service regarding the United States federal income tax consequences of the Reverse Stock Split.

PLEASE CONSULT YOUR OWN TAX ADVISOR CONCERNING THE CONSEQUENCES OF THE REVERSE STOCK SPLIT IN YOUR PARTICULAR CIRCUMSTANCES UNDER THE CODE AND THE LAWS OF ANY OTHER TAXING JURISDICTION.

Tax Consequences to United States Holders of Common Stock. A United States holder, as used herein, is a stockholder who or that is, for United States federal income tax purposes: (a) a citizen or individual resident of the United States, (b) a domestic corporation, (c) an estate whose income is subject to United States federal income tax regardless of its source, or (d) a trust, if a United States court can exercise primary supervision over the trust’s administration and one or more United States persons are authorized to control all substantial decisions of the trust. This discussion applies only to United States holders.

No gain or loss should be recognized by a stockholder upon such stockholder’s exchange of pre-Reverse Stock Split shares of common stock for post-Reverse Stock Split shares of common stock pursuant to the Reverse Stock

44

Split, except in respect of cash, if any, received in lieu of a fractional share. In general, the aggregate adjusted basis of the post-Reverse Stock Split shares of common stock received will be the same as the aggregate adjusted basis of the common stock exchanged for such new shares (excluding any portion of the stockholder’s basis allocated to a fractional share), and the stockholder’s holding period for the post-Reverse Stock Split shares of common stock will include the period during which the stockholder held the pre-Reverse Stock Split shares of common stock surrendered. Treasury regulations provide detailed rules for allocating the tax basis and holding period of the shares of common stock surrendered to the shares of common stock received pursuant to the Reverse Stock Split. Stockholders of shares of common stock acquired on different dates and at different prices should consult their tax advisors regarding the allocation of the tax basis and holding period of such shares.

Generally, the receipt of cash in lieu of a fractional share will be treated as though such fractional share had been redeemed by us in exchange for the cash payment. The cash payment will be taxed either as a dividend to the extent of the stockholder’s ratable share of our earnings and profits (as that term is used in Section 316 of the Code), if any, or as capital gain or loss. Gain, if any, realized by a stockholder on the transaction will be recognized in an amount not in excess of the cash received. The determination whether the receipt of cash has the effect of the distribution of a dividend is made by applying the rules under Section 302 of the Code. Stockholders should consult their tax advisor regarding the U.S. federal income tax consequences of the receipt of cash in lieu of fractional shares.

Accounting Consequences of the Reverse Stock Split

Following the Effective Date of the Reverse Stock Split, if any, the net income or loss and net book value per share of common stock will be increased because there will be fewer shares of the common stock outstanding. The Company does not anticipate that any other accounting consequences would arise as a result of the Reverse Stock Split.

Interests of Directors and Executive Officers

The directors and officers of the Company have no substantial interests, directly or indirectly, in the Reverse Stock Split Proposal, except to the extent of their ownership of the Company’s Class A Common Stock.

Vote Required and Recommendation

The affirmative vote of a majority of the votes cast by the stockholders present in person or represented by proxy at the annual meeting and entitled to vote thereon is required for approval of the Reverse Stock Split Proposal. This means that the proposal will be approved only if the shares voted FOR the proposal exceed the number voted AGAINST the proposal. You may vote FOR or AGAINST the proposal or you may ABSTAIN. Votes cast FOR or AGAINST approval of this matter will be counted as shares entitled to vote on the matter. Broker non-votes will also be counted as shares entitled to vote on this matter. Abstentions will count for quorum purposes but will not count as shares entitled to vote on this matter.

THE BOARD RECOMMENDS THAT YOU VOTE “FOR” APPROVAL OF THE REVERSE STOCK SPLIT PROPOSAL.

STOCKHOLDERS WITH THE SAME LAST NAME AND ADDRESS

The SEC rules permit companies and intermediaries (such as brokers) to implement a delivery procedure known as “householding.” Under this procedure, multiple Altus stockholders who reside at the same address may receive a single set of proxy materials, unless one or more of the stockholders has provided contrary instructions. This procedure reduces printing costs and postage fees and saves natural resources.

If you hold your shares in “street name” (your shares are held in a brokerage account or by a bank or other nominee), you may revoke your consent to householding at any time by writing to Broadridge, Householding

46

Department, 51 Mercedes Way, Edgewood, New York 11717 or calling Broadridge at 1-866-540-7095. You can also request information about householding from your broker or bank.

If you are a stockholder of record (your shares are held in your own name and not held in a brokerage account) who received a household mailing this year, and you would like to have additional copies of proxy materials promptly mailed to you or if you would like to opt out of householding for future mailings, please send your written request to American Stock Transfer & Trust Company, LLC, ATTN: AST Mail Services, 6201 15th Avenue, Brooklyn, New York 11219 or call 718-921-8124.

SOLICITATION OF PROXIES

This proxy is solicited by the Board for use at the annual meeting and any adjournment thereof. Solicitation of proxies for use at the annual meeting may be made in person or by mail, telephone, or other electronic means by directors, officers, and regular employees, if any, of the Company. These persons will receive no special compensation for any solicitation activities. The Company has requested banking institutions, brokerage firms, custodians, trustees, nominees, and fiduciaries to forward solicitation materials to the beneficial owners of shares of the Company’s common stock for whom they are record holder, and the Company will, upon request, reimburse reasonable forwarding expenses.

INCORPORATION OF CERTAIN INFORMATION BY REFERENCE

Appendix A

Amendment to Second Amended and Restated

Certificate of Incorporation of Kayne Anderson Acquisition Corp.

Under Section 242 of the Delaware General Corporation Law, Altus Midstream Company, a corporation organized and existing under the laws of the State of Delaware (the “Corporation”), hereby certifies as follows:

FIRST: The Second Amended and Restated Certificate of Incorporation of the Corporation is hereby amended by replacing Section 4.1 in its entirety as follows:

Section 4.1 Authorized Capital Stock.

(a)    The total number of shares of all classes of capital stock, each with a par value of $0.0001 per share, which the Corporation is authorized to issue is 3,050,000,000 shares, consisting of (i) 3,000,000,000 shares of common stock (the “Common Stock”), consisting of (x) 1,500,000,000 shares of Class A Common Stock (the “Class A Common Stock”) and (y) 1,500,000,000 shares of Class C Common Stock (the “Class C Common Stock”), and (ii) 50,000,000 shares of preferred stock, par value $0.0001 per share (the “Preferred Stock”).

(b)    Reverse Stock Split.

(i)    Effective as of 5:30 p.m., Eastern Time, on                 , 2020 (the “Effective Time”), every twenty (20) shares of the Corporation’s Common Stock (the “Old Common Stock”), issued and outstanding immediately prior to the Effective Time, will be automatically reclassified as and converted into one (1) share of Common Stock of the Corporation (the “New Common Stock”) (such formula herein, the “Determined Ratio”). Further, every right, option and warrant to acquire shares of Old Common Stock outstanding immediately prior to the Effective Time shall, as of the Effective Time and without any further action, automatically be reclassified into the right to acquire one (1) share of New Common Stock based on the Determined Ratio of shares of Old Common Stock to shares of New Common Stock, but otherwise upon the terms of such right, option or warrant (except that the exercise or purchase price of such right, option or warrant shall be proportionately adjusted).

(ii)    Notwithstanding the immediately preceding paragraph, the Corporation shall not be required to issue or deliver any fractional shares of New Common Stock. At the Effective Time any such fractional interest in such shares of New Common Stock shall be converted into the right to receive an amount in cash, without interest, determined by multiplying (1) the volume-weighted average trading price of the Common Stock (on a post-reverse-split basis as adjusted for the amendment effected hereby) as reported on the Nasdaq Global Select Market for the twenty consecutive trading days ending on the trading day immediately preceding the Effective Time by (2) such fractional share interest to which the holder would otherwise be entitled. Shares of Common Stock that were outstanding immediately prior to the Effective Time and that are not outstanding immediately after the Effective Time shall resume the status of authorized but unissued shares of Common Stock.

(iii)    Each stock certificate that, immediately prior to the Effective Time, represented shares of Old Common Stock shall, from and after the Effective Time, represent that number of whole shares of New Common Stock into which the shares of Old Common Stock represented by such certificate shall have been reclassified (as well as the right to receive cash in lieu of any fractional shares of New Common Stock as set forth above); provided, however, that each holder of record of a certificate that represented shares of Old Common Stock shall receive, upon surrender of such certificate, a new certificate representing the number of whole shares of New Common Stock into which the shares of Old Common Stock represented by such certificate shall have been reclassified, as well as any cash in lieu of fractional shares of New Common Stock to which such holder may be entitled pursuant to the immediately preceding paragraph.

SECOND: The foregoing amendment has been duly adopted in accordance with the provisions of Section 242 of the General Corporation law of the State of Delaware by the vote of a majority of the outstanding common stock of the Corporation entitled to vote thereon.

A-1

THIRD: This Certificate shall be effective as of 5:30 p.m., Eastern Time, on the date this Certificate is filed with the Secretary of State of the State of Delaware.

IN WITNESS WHEREOF, I have signed this Certificate this          day of                 , 2020.
