### **Leadership Transition** 
Pursuant to our previously announced leadership transition plan, Travis D. Stice stepped down as Chief Executive Officer at the conclusion of the Company's 2025 Annual Meeting of stockholders (the "2025 Annual Meeting"), after leading the Company as Chief Executive Officer since January 2012 and joining the board of directors in November 2012 following the Company's initial public offering. Mr. Stice transitioned to Executive Chairman of the Board at that time, and Kaes Van't Hof, then President of the Company, succeeded Mr. Stice as Chief Executive Officer. In accordance with the letter agreement with Mr. Stice specifying the terms on which he will serve as Executive Chairman, Mr. Stice will transition to non-executive Chairman of the Board at the conclusion of the Company's 2026 Annual Meeting of stockholders (the "2026 Annual Meeting").

### **Endeavor Merger and Stephens Stockholders Agreement** 
In February 2024, the Company announced its transformative, $26 billion merger with Endeavor Energy Resources, L.P. ("Endeavor" and such transaction, the "Endeavor Merger"). The Endeavor Merger closed on September 10, 2024. At closing, the Company entered into a Stockholders Agreement (the "Stephens Stockholders Agreement") with the former holders of all the issued and outstanding equity interests in Endeavor who received Company common stock in the Endeavor Merger as consideration (such stockholders, the "Stephens Stockholders").

Pursuant to the terms of the Stephens Stockholders Agreement, the Stephens Stockholders have the right to designate four individuals to serve on our board of directors. The number of individuals that the Stephens Stockholders are entitled to designate to serve on our board of directors will be permanently reduced to (i) two directors, if, at any time, the Stephens Stockholders beneficially own at least 20% of the Company's outstanding common stock, but less than 25% of the Company's outstanding common stock, (ii) one director, if, at any time, the Stephens Stockholders beneficially own at least 10% of the Company's outstanding common stock, but less than 20% of the Company's outstanding common stock and (iii) no directors, if, at any time, the Stephens Stockholders beneficially own less than 10% of the Company's outstanding common stock. The foregoing description of the certain provisions of the Stephens Stockholders Agreement does not purport to be complete and is qualified in its entirety by reference to the actual terms of the Stephens Stockholders Agreement, a copy of which is attached as Exhibit 10.1 to the Form 8-K filed by the Company with the Securities and Exchange Commission on September 10, 2024.

***DIAMONDBACK ENERGY, INC.*** • 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **6**

[Back to Contents](#toc)

Diamondback appreciates our social and environmental license to operate as a public oil and gas company in the United States and acknowledges that such license will continue to be influenced by our stockholders and the alignment of our sustainability and governance approach with their expectations. We regularly engage with our stockholders on these matters to ensure alignment. At its core, our sustainability and environmental strategy reflects our principled stakeholder-driven approach, focusing on ethics, integrity, risk management, regulatory compliance, protection of our environment and communities and feedback received from our stakeholders. The foremost authorities on energy demand continue to forecast that oil and gas will account for a substantial portion of global energy demand well into the future, in even the most carbon constrained projections. However, we continue to integrate sustainability into our core, thus allowing for our continued future success.

As Diamondback's sustainability strategy evolves, management regularly interacts with the board and its committees regarding such matters, including its audit committee, compensation committee, nominating and corporate governance committee and safety, sustainability and corporate responsibility committee. The safety, sustainability and corporate responsibility committee was formed in 2019 to (i) review Diamondback's policies and performance regarding, and provide guidance on, environmental and safety matters, (ii) advise the board of directors and management on significant public issues that are pertinent to the Company and (iii) assist management in setting strategy, establishing goals and integrating sustainability and prudent governance into strategic and tactical business activities across the Company.

In 2025, Diamondback continued to include specific, measurable environmental and safety performance metrics in our short-term incentive compensation program that incentivize performance on key metrics, including flaring, greenhouse gas (GHG) emissions, non-fresh water usage, fluid spill control and safety.

Diamondback also released its eighth annual Corporate Sustainability Report in September 2025, which included content aligned to voluntary frameworks and standards maintained by the Sustainability Accounting Standards Board (SASB), Task Force on Climate-Related Financial Disclosures (TCFD), Global Reporting Initiative (GRI), International Petroleum Industry Environmental Conservation Association (IPIECA) and the American Exploration and Production Council (AXPC). Our 2025 Corporate Sustainability Report also included:

&nbsp;&nbsp;&nbsp;&nbsp;• our Scope 1 and Scope 2 GHG emissions;

• a calculation of our Scope 3 GHG emissions;

• an assessment of our portfolio under various low carbon scenarios as outlined by the International
 Energy Agency;

• our 2024 EEO-1 data; and

• a limited assurance
 attestation from our independent auditor.

Further, Diamondback completed CDP Global's (CDP) 2025 Corporate Questionnaire. Both the 2025 Corporate Sustainability Report and a link to our CDP Corporate Questionnaire can be found on our website under the tab "Sustainability."

Diamondback remains committed to conducting its business in a manner that respects and promotes the fundamental rights and dignity of all people in accordance with its robust Human Rights Policy. A copy of Diamondback's Human Rights Policy can be found on our website under the tab "Investors—Corporate Governance."

For additional information regarding our commitment to environmental and safety matters, please see "Corporate Responsibility and Sustainability" beginning on page 33.

---

## **—** **DIRECTOR NOMINATIONS** 
The board is committed to recruiting and nominating directors for election who will collectively provide the board with the necessary diversity of skills, backgrounds and experiences to meet the Company's ongoing needs and support oversight of our business strategy and priorities, while maintaining institutional knowledge. In recommending candidates for election to the board, the nominating and corporate governance committee evaluates a candidate's character, judgment, skill set, experience, independence, other time commitments and any other factors that the nominating and corporate governance committee deems relevant in light of the current needs of the board. The board believes it is important to have board membership reflecting a range of backgrounds, skills, and experiences and as a result, has an experienced and diverse nominee slate.

To reflect the determination to keep our board diverse, the nominating and corporate governance committee seeks to include a broad pool of candidates in all current or future director searches, including by affirmatively instructing any search firms retained to assist the committee in identifying director candidates to seek to include candidates with varied backgrounds and experiences. In addition, in determining whether to recommend incumbent directors for re-election to the board, the nominating and corporate governance committee also reviews and considers the director's board and committee meeting attendance, the level of support that the director's nomination received at the most recent annual stockholders' meeting, director tenure and the well-roundedness of the board as a whole.

As described above, pursuant to the terms of the Stephens Stockholders Agreement, the Stephens Stockholders currently have the right to designate four individuals to serve on our board of directors. The Stephens Stockholders have designated Darin G. Holderness, Charles A. Meloy, Robert K. Reeves and Lance W. Robertson to serve on our board of directors.

In 2026, the nominating and corporate governance committee recommended to the board, and the board approved, the nomination of Travis D. Stice, Kaes Van't Hof, Vincent K. Brooks, Darin G. Holderness, Rebecca A. Klein, Stephanie K. Mains, Charles A. Meloy, Mark L. Plaumann, Robert K. Reeves, Lance W. Robertson, Melanie M. Trent, Frank D. Tsuru and Steven E. West to serve for a one-year term ending at the 2027 Annual Meeting, but in any event, until his or her successor is elected and qualified, unless ended earlier due to his or her death, resignation, disqualification or removal from office. All of the director nominees, except for Messrs. Meloy, Stice and Van't Hof, are independent under The Nasdaq Stock Market LLC (Nasdaq) listing standards and the applicable SEC rules, and assuming all of these director nominees are elected by the stockholders at the 2026 Annual Meeting, approximately 77% of our board of directors will consist of independent directors.

### **About Director Nominees** 
Members of our board of directors are elected annually. In the event any nominee should be unavailable to serve at the time of the meeting, the proxies may be voted for a substitute nominee selected by the board.

Biographical information with respect to each of the 13 director nominees, together with a list of competencies that contributed to the conclusion that such person should serve as a director, are presented below. An overview of the core competencies of each director nominee is featured in a skills matrix on page 19. Ages are as of April 9, 2026.

### **Limits on Board Service and Audit Committee Service** 
Our Corporate Governance Guidelines establish the following limits on our directors serving on public company boards and audit committees:

---

| | |
|:---|:---|
| **Director Category** | **Limits on Public Company Boards and<br> Audit Committee Service, including Diamondback** |
| All Directors | Four Boards |
| Directors Who Serve as CEO of a Public Company | Two Boards |
| Directors Who Serve on Audit Committees | Three Audit Committees |

---

Our Corporate Governance Guidelines provide that prior to accepting an invitation to serve on the board of another public company or other for-profit entity or accepting membership of the audit committee of the board of another public company or other for-profit entity, a director must (i) provide timely notice to the chair of the nominating and corporate governance committee, with a copy to the Chairman of the Board, the Lead Independent Director and the Corporate Secretary, and (ii) obtain approval from the nominating and corporate governance committee based upon its review of the opportunity in light of factors it deems relevant, including possible conflicts of interest, whether the opportunity would create any legal or regulatory issues, or conflict with any of our corporate governance policies, the director's status as an independent director and any constraints on the director's time that would detract from the director's ability to serve the Company. The nominating and corporate governance committee reviews compliance with our director overboarding policy on an annual basis. All directors are currently in compliance with our director overboarding policy related to limits on board service and audit committee service.

## **—** **DIRECTOR QUALIFICATIONS AND NOMINATION PROCESS** 

### **Skills and Qualifications We Seek in Directors** 
As provided by the nominating and corporate governance committee's charter and our Corporate Governance Guidelines, our nominating and corporate governance committee identifies, evaluates and recommends to our board of directors candidates with the goal of creating a balance of knowledge, experience and diversity.

It is our policy that potential directors should possess the highest personal and professional ethics, integrity and values, and be committed to representing the interests of our stockholders. We also require that the members of our board of directors be able to dedicate the time and resources sufficient to ensure the diligent performance of their duties on our behalf, including attending all meetings of the board of directors and applicable committee meetings. We also require that at least a majority of our directors meet the standards of independence promulgated by Nasdaq and the SEC. For a discussion of the core competencies that each director brings to our board, see "Summary of Director Nominee Core Competencies" above on page 19.

### **Board Refreshment and Diversity** 
Our nominating and corporate governance committee is committed to continuous improvement and employs a rigorous process to ensure that the composition of the board is diverse, balanced and aligned with the evolving needs of the Company. The board ensures refreshment and continued effectiveness by evaluating the composition of the board on a periodic basis to ensure its composition reflects a range of talents, skills and expertise sufficient to provide sound and prudent guidance with respect to our operations and the interests of our stockholders. In particular, the board seeks to maintain a balance of experience in the areas of accounting and finance, management, leadership and oil and gas related industries as well as other core competencies discussed under "Summary of Director Nominee Core Competencies."

Additionally, it is our policy that our nominating and corporate governance committee consider diversity in its evaluation of candidates for board membership. To this end, our board believes that diversity with respect to viewpoint, including such that is held by candidates of different background, thought and tenure on our board (in connection with the consideration of the renomination of an existing director), should be an important factor in board composition. To reflect this policy and to ensure a competitive recruitment process, our nominating and corporate governance committee, in accordance with its charter, seeks to include diverse candidates in all director searches, taking into account diversity of background, thought and tenure on our board (in connection with the consideration of the renomination of an existing director), including by affirmatively instructing any search firm retained to assist the nominating and corporate governance committee in identifying director candidates to seek to include diverse candidates from

***DIAMONDBACK ENERGY, INC.*** • 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **22**

[Back to Contents](#toc)

traditional and nontraditional candidate groups. In accordance with its charter, our nominating and corporate governance committee also ensures that diversity considerations are discussed in connection with each potential nominee, as well as on a periodic basis in connection with its periodic review of the composition of the board and the size of the board as a whole.

As part of our ongoing commitment to expand the range of talents, skills, expertise and backgrounds on our board, we have increased the size of our board of directors to 13 and otherwise engaged in significant board refreshment efforts, enhancing and diversifying the skill set of our board of directors in the areas of risk management across energy and other industries and the government sector, national security and cybersecurity, sustainability and governance, regulatory and legal compliance.

**How We Select our Director Nominees**

The board is responsible for nominating directors and filling vacancies that may occur between annual meetings, based upon the recommendation of our nominating and corporate governance committee. The nominating and corporate governance committee considers the Company's current needs and long-term and strategic plans to determine the skills, experience and characteristics needed by our board. The nominating and corporate governance committee then identifies, considers and recommends director candidates to the board in light of its commitment to board improvement, refreshment and diversity discussed above. Generally, the committee identifies candidates through the business and organizational contacts of our advisors, directors and management team and through the use of third-party search firms.

The nominating and corporate governance committee, in accordance with its charter and our Corporate Governance Guidelines, takes into consideration the key qualifications and skills described above when evaluating candidates. The nominating and corporate governance committee also considers whether potential candidates will likely satisfy independence standards for service on the board and its committees and the number of public boards on which the candidate already serves.

As described above, pursuant to the terms of the Stephens Stockholders Agreement, the Stephens Stockholders currently have the right to designate four individuals to serve on our board of directors. The Stephens Stockholders have designated Darin G. Holderness, Charles A. Meloy, Robert K. Reeves and Lance W. Robertson to serve on our board of directors. These directors were elected at the 2025 Annual Meeting and have been nominated to continue to serve if elected at the 2026 Annual Meeting.

### **Stockholder Nomination of Candidates and Proxy Access** 
Under the Company's bylaws, we provide proxy access, permitting a stockholder, or a group of up to 20 eligible stockholders, that has continuously owned for no less than three years at least 3% of our outstanding common stock, to nominate and include in our proxy materials up to the greater of two directors and 20% of the number of directors currently serving on the Company's board, provided that the stockholder(s) and the nominee(s) satisfy the requirements specified in our bylaws.

Stockholders who wish to submit a director nomination proposal, but who do not wish to have such nomination included in the Company's proxy materials, must notify the Company in writing of the information required by the provisions of our bylaws dealing with such stockholder proposals.

See "Submission of Future Stockholder Proposals" on page 99 for additional detail and deadlines regarding submitting director nominees.

### **Majority Voting** 
To be elected in uncontested elections such as this one, a director must receive a majority of the votes cast with respect to that director at the meeting. Our bylaws and Corporate Governance Guidelines provide that if the number of shares voted "**FOR**" a nominee who is serving as a director (an incumbent) does not exceed the votes cast "**AGAINST**" that director, he or she will tender his or her resignation to the board. The board will evaluate whether to accept or reject such resignation, or whether other action should be taken. Within 90 days of the certification of the stockholder vote, the board is required to decide whether to accept the resignation and publicly disclose its decision, and if applicable, the rationale for the decision.

[Back to Contents](#toc)

## **—** **DIRECTOR INDEPENDENCE** 
Our Corporate Governance Guidelines provide that a majority of the board of directors must be "independent" in accordance with Nasdaq listing standards. Our board of directors has determined that each of our director nominees, except for Travis D. Stice, Charles A. Meloy and Kaes Van't Hof, meets the standards regarding independence set forth in the Nasdaq listing standards and the applicable SEC rules and is free of any relationship which, in the opinion of our board of directors, would interfere with the exercise of independent judgment in carrying out their responsibilities as directors of the Company. As a result, 10 out of 13 of our director nominees are independent under the Nasdaq listing standards.

Our board of directors has determined that each current member of the audit committee is independent for purposes of serving on such committee under the Nasdaq listing standards and the applicable SEC rules. In addition, our board of directors has determined that each current member of the audit committee is financially literate under the Nasdaq listing standards and that each of Mr. Plaumann, Mr. Holderness, and Ms. Mains qualifies as an "audit committee financial expert," as such term is defined in Item 407(d) of Regulation S-K. The audit committee consists of five independent directors and has three audit committee financial experts.

Our board of directors has also determined that each member of the compensation committee and the nominating and corporate governance committee meets the independence requirements applicable to those committees under the Nasdaq rules. In addition, our board of directors determined that each member of our compensation committee is a "non-employee director" in accordance with Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act").

Although Nasdaq does not set independence standards for the safety, sustainability and corporate responsibility committee, our board of directors values the importance of independence of each board committee, and 3 of the 4 directors who serve on our safety, sustainability and corporate responsibility committee are independent directors.

### **Executive Sessions of Independent Directors** 
Our independent directors have the opportunity to meet in an executive session following each regularly scheduled meeting of the board of directors and its committees. Ms. Trent, our Lead Independent Director, presides over executive sessions of the board of directors, and the committee chairs, each of whom is independent, preside over executive sessions of the committees. Our independent directors met in an executive session twelve times in 2025.

## **—** **BOARD LEADERSHIP STRUCTURE** 
In February 2022, Mr. Stice assumed the role of Chairman of the Board. In February 2025, the Company announced a leadership transition plan, pursuant to which Mr. Stice stepped down as Chief Executive Officer at the conclusion of the 2025 Annual Meeting, after leading the Company as Chief Executive Officer since January 2012 and joining the board of directors in November 2012 following the Company's initial public offering. Mr. Stice transitioned to Executive Chairman of the Board, and Kaes Van't Hof, then President of the Company, succeeded Mr. Stice as Chief Executive Officer. Following the 2026 Annual Meeting, Mr. Stice will transition from the Executive Chairman of the Board to the non-executive Chairman of the Board. In accordance with our Corporate Governance Guidelines, if the Chairman of the Board is otherwise not independent under Nasdaq listing standards, our board of directors is required to designate a Lead Independent Director to complement the Chairman of the Board's role and to serve as the principal liaison between our independent directors and the Chairman of the Board. In February 2022, our board of directors enhanced the role of our current Lead Independent Director, Ms. Trent, to provide effective independent leadership to our board of directors through her clearly defined and robust set of responsibilities, which include the following:

&nbsp;&nbsp;&nbsp;&nbsp;• the authority to preside at all meetings of our board at which the Chairman of the Board is not present;

• the authority to call meetings of the independent directors, and chair all meetings of the independent directors, including executive sessions;

• serving as the primary liaison between the Chairman of the Board and our independent directors;

• coordinating the annual performance reviews of the Chairman of the Board and Chief Executive Officer;

• providing input with respect to meeting schedules, agendas and the information furnished to our board to ensure our board has adequate time and information for discussion;

• being available for consultation and direct communication with major stockholders, as appropriate; and

• having such other duties as may be from time to time designated by our board.

***DIAMONDBACK ENERGY, INC.*** • 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **24**

[Back to Contents](#toc)

Our board of directors believes that its current leadership structure, as well as the leadership structure that will be in place immediately following the 2026 Annual Meeting, best serves the interests of our stockholders because it provides an appropriate balance between strategy development and independent oversight of management. Our board of directors regularly reevaluates the board's leadership structure as part of its evaluation and refreshment process and also considers stockholder feedback on the topic.

We believe that our directors bring a broad range of leadership experience to the boardroom and regularly contribute to the thoughtful discussion involved in effectively overseeing the business and affairs of the Company. In addition, we believe that the atmosphere of our board is collegial, that all board members are well engaged in their responsibilities and that all board members express their views and consider the opinions expressed by other directors.

We also believe that all of our independent directors have demonstrated leadership in business enterprises and other large organizations and are familiar with board processes. Our independent directors are involved in the leadership structure of our board by serving on our audit, compensation, nominating and corporate governance, or safety, sustainability and corporate responsibility committees, each having a separate independent chair. Specifically, the chair of our audit committee oversees the accounting and financial reporting processes, compliance with legal and regulatory requirements and our cybersecurity strategy. The chair of our compensation committee oversees the annual performance evaluation of our Chief Executive Officer and our compensation policies and practices and their impact on risk and risk management. The chair of our nominating and corporate governance committee monitors matters such as the composition of the board and its committees, board performance and best practices in corporate governance. The chair of our safety, sustainability and corporate responsibility committee provides leadership with respect to best practices in the areas of environmental, safety, human capital, sustainability and corporate and social responsibility. As such, each committee chair provides independent leadership for purposes of many important functions delegated by our board of directors to such committee.

## **—** **BOARD MEETINGS, COMMITTEES AND MEMBERSHIP** 
In 2025, our board of directors met 11 times, in person or, remotely via electronic or telephonic means. In addition to these meetings, the board of directors adopted resolutions by unanimous written consent. In 2025, each director attended at least 90% of the meetings of the board of directors and the meetings of the committees on which he or she served. To the extent a director was unable to attend a meeting in 2025, he or she met telephonically with members of senior management to receive a report regarding the materials reviewed at the meeting.

Recognizing that director attendance at our annual meeting can provide our stockholders with an opportunity to communicate with directors about issues affecting the Company, we actively encourage our directors to attend the annual meeting of stockholders. All then-director nominees attended our 2025 Annual Meeting in person.

## **—** **THE BOARD'S ROLE IN RISK OVERSIGHT** 
As an exploration and production company, we face a number of risks, including, but not limited to, risks associated with supply of and demand for oil and natural gas, volatility of oil and natural gas prices, exploring for, developing, producing and delivering oil and natural gas, declining production, environmental and other government regulations and taxes, weather conditions that can affect oil and natural gas operations over a wide area, adequacy of our insurance coverage, political instability or armed conflict in oil and natural gas producing regions, changes in trade policies and the impacts of tariffs, cybersecurity and data privacy, access to water and regulation of produced water, and the overall economic environment. Management is responsible for the day-to-day management of risks we face as a company, while our board of directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our board of directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

Our board of directors believes that full and open communication between management and the board of directors is essential for effective risk management and oversight. Our board of directors meets regularly with our executive officers to discuss strategy and risks facing the Company. Our executive officers regularly attend our board meetings and are available to address any questions or concerns raised by the board on risk management-related and any other matters. Other members of our management team periodically attend the board meetings or are otherwise available to confer with our board to the extent their expertise is required to address risk management matters. Periodically, our board of directors receives presentations from senior management on strategic matters involving our operations. During such meetings, our board of directors also discusses strategies, key challenges, and risks and opportunities for the Company with senior management.

### **Committee Risk Oversight Responsibilities** 
While our board of directors is ultimately responsible for enterprise-wide risk oversight, the board's four committees assist the board in fulfilling its oversight responsibilities in certain areas of risk.

The audit committee assists the board in fulfilling its oversight responsibilities with respect to risk management in the areas of financial reporting, internal controls and compliance with legal and regulatory requirements, and discusses policies with respect to risk assessment and risk management, including with respect to cybersecurity, which plays an integral role in our risk management strategy and continues to be an area of increasing focus for our board, the audit committee and our management team. For additional information, see "Cybersecurity Risk Management and Governance" on page 36.

The compensation committee assists the board in fulfilling its oversight responsibilities with respect to the management of risks arising from our compensation policies and programs.

The nominating and corporate governance committee assists the board in fulfilling its oversight responsibilities with respect to the management of risks associated with the board's organization, membership and structure and corporate governance.

The safety, sustainability and corporate responsibility committee assists the board in fulfilling its oversight responsibility over management's monitoring and adherence to the Company's policies on sustainability and governance matters and the quality of the Company's procedures for identifying, assessing, monitoring and managing the principal environmental, health, climate change, human capital, safety and social risks in the Company's business.

## **—** **STOCKHOLDER ENGAGEMENT** 
We value the views of our stockholders and embrace active stockholder engagement as an important tenet of good governance. Because positive and ongoing dialogue builds informed relationships that promote transparency and accountability, members of senior management engage with our stockholders on a year-round basis, including proactive outreach as well as responsiveness to specific areas of focus. Information and feedback received through our engagement activities is shared with our board, which helps inform its decisions. In response to feedback obtained during our stockholder outreach efforts, the following past actions, some of which have already been independently considered for implementation by our board of directors or committees, were undertaken:

&nbsp;&nbsp;&nbsp;&nbsp;• Our board of directors amended our bylaws to provide our stockholders with proxy access;

• Our board of directors also amended our bylaws to provide for the majority vote requirement to elect directors to our board, which replaced the prior plurality voting standard applicable to our director election;

• Amended our charter to eliminate the 66 2/3% supermajority vote requirements;

• Amended our governing documents to provide stockholders with the right to call a special meeting;

***DIAMONDBACK ENERGY, INC.*** • 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **30**

[Back to Contents](#toc)

&nbsp;&nbsp;&nbsp;&nbsp;• Our board of directors and the nominating and corporate governance committee approved enhancements to the nominating committee charter and director nomination process that focused on increasing the size of the board and number of independent directors, with a supermajority of the board currently being independent;

• Our board of directors created the safety, sustainability and corporate responsibility committee focused on sound strategy and best policies and practices regarding environmental, safety, human capital and social responsibility matters;

• Our board of directors adopted and annually evaluates Corporate Governance Guidelines as an additional step to reinforce our commitment to prudent corporate governance practices and policies;

• The compensation committee eliminated single-trigger change of control provisions in all Company equity awards granted since the beginning of 2018;

• The compensation committee enhanced the disclosure of targets and goals for performance-based awards, the discussion of equity award process for our named executive officers and the underlying rationale for such awards;

• The compensation committee added return on average capital employed and environmental and safety goals among metrics for determining cash performance awards beginning in 2020 and maintained the weighting attributable to the environmental and safety component of our annual incentive metrics at 25% for 2025;

• Our board of directors implemented and maintains rigorous stock ownership and retention guidelines for our executive officers and non-employee directors;

• Our board of directors adopted a comprehensive executive incentive compensation clawback policy compliant with Nasdaq listing standards and implementing Rule 10D-1 of the Exchange Act;

• Our Lead Independent Director participated in an investor outreach call with one of our large stockholders;

• Our board of directors adopted a Human Rights Policy; and

• Our safety, sustainability and corporate responsibility committee adopted a Policy Governing Corporate Political Contributions.

During 2025 and through the first quarter of 2026, we continued our stockholder outreach efforts and solicited feedback on our executive compensation programs, corporate governance, human capital programs and strategies, corporate responsibility, environmental and sustainability matters and other important issues. We initiated contact with stockholders representing approximately 77% of our outstanding shares as of June 30, 2025. One or more of our Executive Chairman, Lead Independent Director and Chief Executive Officer and other key members of Company senior management spoke with stockholders representing approximately 49% of our outstanding shares as of June 30, 2025, including five of our 10 largest stockholders. In addition, members of Company senior management attended approximately 19 virtual or in person investor conferences and hosted approximately six virtual or in person bus tours. We also discussed certain topics noted above with other investors during investor presentation events and earnings and other investor calls throughout the year.

These discussions have provided us with an opportunity to further explore issues important to us and our stockholders, including corporate governance policies, human capital programs and strategies, executive compensation and corporate sustainability and environmental policies. In 2025, approximately 97.2% of votes cast by our stockholders were in favor of our say-on-pay proposal. Although this vote demonstrates substantial support for our executive compensation programs, representatives of our board and management team continued to undertake stockholder engagement efforts to, among other things, solicit stockholder input on our executive compensation program and ensure ongoing stockholder support of our executive compensation programs. We look forward to continued engagement with stockholders throughout the year so that we can incorporate their ideas to further strengthen our executive compensation programs, continue our commitment to environmental and sustainability matters, improve our disclosure practices and enhance our governance practices.

## **—** **TRADING IN COMPANY SECURITIES** 
We have adopted general and supplemental insider trading policies that govern transactions in securities by our directors, executive officers and other employees. We believe these policies are reasonably designed to promote compliance with applicable insider trading laws, rules and regulations, and Nasdaq listing standards. Our general insider trading policy prohibits our directors, officers and employees from engaging in hedging transactions, trading in puts or calls or engaging in short sales with respect to Company securities and securities of the Company's publicly traded subsidiary Viper Energy, Inc. ("Viper"). Under our supplemental insider trading policy, directors, executive officers and certain "designated persons" are also prohibited from holding such securities in a margin account or otherwise pledging such securities as collateral for a loan. Additionally, directors, executive officers and certain other "designated persons" are only allowed to trade in, donate or otherwise gift Company or Viper securities, as applicable, during the applicable designated trading windows, and must obtain approval from our compliance officer prior to any such trade, donation or gift, except such restrictions do not generally apply to transactions under any pre-arranged trading plans meeting the requirements of SEC Rule 10b5-1(c). Our general and supplemental insider trading policies were included as Exhibit 19.1 and 19.2, respectively, to our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

## **—** **COMMUNICATIONS WITH THE BOARD** 
Individuals may communicate with our board of directors or individual directors by writing to Corporate Secretary, Diamondback Energy, Inc., 500 West Texas Ave, Suite 100, Midland, TX 79701. Our Corporate Secretary will review all such correspondence and forward to our board of directors a summary of all such correspondence and copies of all correspondence that, in the opinion of our Corporate Secretary, relates to the functions of our board of directors or any committee thereof or that he otherwise determines requires their attention. Directors may review a log of all such correspondence received by us and request copies. Concerns relating to accounting, internal control over financial reporting or auditing matters will be immediately brought to the attention of the chair of the audit committee and handled in accordance with the audit committee procedures established with respect to such matters.

## **—** **DIRECTOR COMPENSATION** 
Members of our board of directors who are also officers or employees of the Company do not receive compensation for their services as directors. Further details regarding our director compensation in 2025 are set forth under the heading "Compensation Tables—2025 Director Compensation."

## **—** **CORPORATE RESPONSIBILITY AND SUSTAINABILITY** 
As an oil and gas company, we understand that we have the potential to make a uniquely positive impact on the world. We provide affordable, domestically produced energy that helps run our homes, businesses, transportation networks and other key components of our economy. As we continue to provide a critical product that contributes to economic growth and society, we view the connection between responsible operations and business success a fundamental necessity. We are committed to the safe and responsible development of our resources in the Permian Basin. We operate in the same areas in which the overwhelming majority of our employees and their families live and are dedicated to preserving and protecting the environment for the benefit of our stockholders, employees, our community and other stakeholders.

We have identified key areas of focus, including energy, emissions, waste and spills, water use, compliance, health and safety, training and education, human capital and community, and have described below certain of our efforts relating to these areas. We have also established the safety, sustainability and corporate responsibility committee of our board of directors that oversees, among other things, our management's monitoring and adherence to our policies on environmental responsibility and sustainability matters and the quality of our procedures for identifying, assessing, monitoring and managing the principal environmental, health, climate change, human capital, safety and social risks in our business. Our safety, sustainability and corporate responsibility committee also provides leadership with respect to best practices in environmental responsibility, sustainability and corporate and social responsibility.

In 2019, Diamondback set ambitious medium-term environmental targets with respect to reduction of Scope 1 GHG intensity and methane intensity. At the time, we set these goals with what we believed to be an informed view of our future operations and regulatory framework. Since the time the Company set these goals, we have completed multiple, large acquisitions that have added significant new assets to our operations, and the Company was historically able to maintain a path toward achieving these targets. Recently, regulatory frameworks for environmental reporting standards have evolved in the jurisdictions where we operate. Under the new reporting framework, certain emissions factors were significantly increased, and such new factors result in emissions outcomes being recalculated at higher levels that do not align with the assumptions underlying the targets the Company set in 2019. These regulatory framework changes, as well as the significant impact of the Endeavor Merger on our asset base, impacted our ability to achieve the medium-term targets we established in 2019.

To underscore our commitment to carbon neutrality, we have maintained our "Net Zero Now" initiative under which we strive to produce every hydrocarbon molecule with zero net Scope 1 emissions. We have also maintained our target to reduce combined Scope 1 and 2 GHG intensity by at least 50% from 2020 levels by 2030. In addition, as detailed in our 2025 Corporate Sustainability Report published in September 2025, we established new medium-term environmental targets to (i) reduce methane intensity by at least 20% from 2024 levels by 2030 and (ii) maintain peer leading Scope 1 GHG intensity at 2024 levels. We are proud of the progress we have made in the past six years.

### **Commitment to Environmental Responsibility** 
We are committed to the exploration, exploitation, acquisition and production of oil, natural gas and natural gas liquids in an environmentally responsible manner and in compliance with applicable federal, state and local laws, including laws regulating emissions of greenhouse gases, such as methane. We take actions beyond those required by law to reduce methane emissions, use an increasing percentage of non-potable water and make significant investments in infrastructure to reduce environmental impact.

In keeping with that commitment, our overall approach includes these key activities:

&nbsp;&nbsp;&nbsp;&nbsp;• Investing in and implementing the best available control technology (BACT) and
 innovative methods for drilling and completing wells, which has allowed us to achieve the same or improved results with less
 proppant, fewer wells and a greatly reduced environmental footprint;

• Minimizing our environmental impact and improving safety for all stakeholders;

• Implementing our "Net Zero Now" initiative under which, effective January 1, 2021,
 every hydrocarbon molecule we produce is anticipated to be produced with zero net Scope 1 GHG emissions;

***DIAMONDBACK ENERGY, INC.*** • 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **33**

[Back to Contents](#toc)

&nbsp;&nbsp;&nbsp;&nbsp;• Purchasing carbon credits to offset the remaining emissions to the extent our
 GHG and methane intensity reduction efforts do not eliminate our Scope 1 GHG emissions;

• Achieving and exceeding our 2025 goal to source over 65% of our water used for drilling and
 completion operations from recycled sources in both 2023 and 2024;

• Maintaining the commitment to reduce combined Scope 1 and Scope 2 GHG intensity by at least
 50% from 2020 levels by 2030;

• Achieving goal to Eliminate routine flaring (as defined by the World Bank) by 2025;

• Motivating our executive team, senior management and all of our employees to strive to achieve
 measurable targets and goals with respect to flaring associated with the Company's operations, non-fresh water use,
 GHG emission intensity and produced liquids spills; the weighting of current environmental and safety performance metrics
 in the 2025 short-term annual incentive compensation plan is 25%;

• Minimizing use of potable water in our operations;

• Safely transporting oil and gas and minimizing impacts from air emissions, flared gas and
 spills;

• Maximizing fluid transportation via pipelines rather than diesel powered trucks;

• As part of our flare reduction and mitigation strategy for non-routine flaring, we (i) include
 performance-based incentives and penalties related to flaring in our midstream contracts and (ii) negotiated downstream commitments
 and other offload arrangements;

• Hosting bi-annual in-person meetings with major midstream partners to improve operational
 collaboration and mitigate flaring;

• Replacing natural gas-controlled pneumatic devices on some of our older tank batteries with
 air-controlled pneumatic devices when operationally feasible and pursuing initiatives to install air-controlled pneumatic
 devices on new tank batteries;

• Achieving over 90% of oil production monitored by Continuous Emissions Methane Systems (CEMS);

• Adding Gas Mapping LiDAR (GML) systems mounted on aircraft to our methane monitoring strategy
 providing primary coverage for "final 10%" of facilities and quarterly supplemental monitoring for OOOOa/b assets;

• Actively working to obtain multiple gas sales connections at our larger gas-producing batteries
 wherever possible, allowing us to sell gas to the secondary outlet and minimize flaring in the event a third-party gatherer
 and processor has planned maintenance or experiences an unplanned event that prevents them from taking our gas;

• Continuing to electrify many of our gas compression services and equipment;

• Constructing and operating company-owned electric substations to maintain better control and
 limit use of local generation;

• Continuing efforts to tie-in flare monitoring to our tank battery SCADA systems; and

• Continued to grow our inventory of wells drilled by rigs on electricity supplied directly
 from utility power.

### **Commitment to Human Capital** 
Our strategy of operational excellence is achieved by our people through our disciplined culture grounded in clarity, efficiency and inclusion. We are extremely committed to our culture which is built upon the solid foundation of our five core values: leadership, integrity, excellence, people and teamwork, which guide how we operate and interact across our organization. We understand our success is based upon not just what we do, but how we do it. Therefore, we set a high bar for all of our employees in terms of how they operate and interact, both in the office and in the field. We challenge our workforce to ensure all people are treated with dignity and respect. The key elements of our human capital programs and strategies are described below.

#### **Oversight by Board of Directors** 
Our board of directors provides oversight of our human capital strategies with the assistance of its board committees, specifically the safety, sustainability, and corporate responsibility committee and the compensation committee. Our safety, sustainability, and corporate responsibility committee is responsible for the oversight of our human capital programs related to recruiting, retention, training, and development. The safety, sustainability, and corporate responsibility committee receives regular updates from our executive leadership, senior management and third-party consultants on human capital trends and other key human capital matters impacting our business. We believe our board's oversight of these matters helps the Company identify and mitigate exposure to human capital risks.

***DIAMONDBACK ENERGY, INC.*** • 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **34**

[Back to Contents](#toc)

#### **Commitment to Protecting People** 
Our organizational culture fosters teamwork and open dialogues about work practices, which includes putting safety first. Whether it is minimizing workplace incidents or preparing for the unexpected, we continue to make protecting our people a fundamental component of our corporate responsibility efforts. We maintain a formal health and safety program that includes employee training, new hire orientation, and ongoing education on a variety of environmental and safety topics, including proper reporting procedures. We also ensure our employees have all necessary equipment to operate safely. Employees undergo significant training and education each year to become knowledgeable on regulatory compliance, industry standards and innovative opportunities to effectively manage the challenges of developing our resources. In light of the nature of our work and the locations of some sites in and near communities, we also proactively prepare for the unexpected by developing emergency response plans designed to address potentially hazardous situations.

For 2025, we also continued to demonstrate our commitment to safety by maintaining a performance metric in our annual incentive compensation scorecard that measures our total recordable incident rate. Our health, safety and environmental organization includes full-time, field-dedicated coordinators to monitor facilities and proactively help prevent potential issues.

#### **Equal Opportunity, Recruiting and Retention** 
Fair, consistent and equitable treatment of our employees is core to how we manage our dedicated workforce. Our employment decisions are based on merit, qualifications, competencies, and demonstrated contributions. We actively seek to attract and retain top talent and continue to cultivate a respectful work environment. We value the perspectives, experiences and ideas contributed by our employees from a wide range of backgrounds. As of December 31, 2025, over 25% of our employees were women, and more than 40% of our employees self-identified as ethnic minorities. We publicly disclosed our 2024 Equal Employment Opportunity (EEO-1) data as of December 31, 2024 in our 2025 Corporate Sustainability Report published in September 2025.

In 2025, we expanded our recruitment efforts, particularly in our college recruitment and internship programs. We collaborated with several student organizations to reinforce this inclusive initiative, which will continue in the future. In addition, we targeted experienced hires to attract and retain top industry talent.

#### **Total Reward – Performance Based Compensation** 
We value results and believe in recognizing and rewarding performance. Our comprehensive total reward compensation philosophy is rooted in a real-time market-based approach, where we reward and recognize value creation and cultural alignment. We participate in industry-specific benchmarking surveys ensuring comparison points against local markets in a comprehensive manner. Overall, our employee compensation programs consist of an annual base salary, a discretionary performance-based annual cash incentive award and a discretionary long-term equity incentive award. All of our employees are eligible for the discretionary long-term equity incentive awards and discretionary short-term cash incentive awards based on both specific Company performance metrics tied to the same scorecard as the executive annual incentive awards and individual performance outcomes. These awards are a central part of ensuring that we competitively reward our employees in order to attract and retain top talent, as well as ensuring that their work efforts align with our stockholders by providing stock ownership opportunities for 100% of our employees.

#### **Health and Wellness** 
We recognize that a strong health and wellness culture is important to our employees and positively impacts their engagement in their jobs and communities. We offer our employees robust health and wellness benefits, and employees do not pay any health insurance premiums for core coverage such as medical, dental, vision, long-term disability and life insurance, resulting in a high level of enrollment by our employees. Further, we offer a competitive Company match on 401(k) retirement savings, and employees are immediately vested in their contributions as well as the Company matching dollars. Our retirement savings plan allows employees to choose between pre-tax or post-tax (ROTH) contributions, allowing them to plan for retirement in the format which best meets individual financial objectives.

Our benefits program also includes health savings and flexible spending accounts, a private family clinic, a child learning center, paid time off, education assistance, gym reimbursement, volunteer time off, extended time off, and paid maternity and paternity leave. We also offer our employees the opportunity to work a flexible work schedule under which, during the standard two week pay period, an employee works a minimum of eight 9-hour days and two 4-hour days (Fridays). We continue with our commitment to a flexible work life balance by offering a work from home policy which provides office-based employees with a bank of days that they may utilize to work remotely.

#### **Training and Development** 
Our training and development opportunities are designed to expand the professional knowledge of our team. Most offerings are provided across the organization to all employees at any level. We also supplement formal training with on-the-job learning opportunities that allow employees to apply new knowledge, practice work activities and develop a broad range of skills. Our internal course offerings in 2025 and through the first quarter of 2026 included a wide array of topics such as extensive cybersecurity, safety and other compliance training sessions. Additionally, our new hires undergo training and education on our Code of Business Conduct and Ethics. Our employees also receive training on regulatory compliance, industry standards and innovative opportunities to effectively manage the challenges of developing our oil and gas resources and related environmental and social responsibility. We have also implemented development programs that are designed to support learning, collaboration, and leadership capabilities at all levels of the organization. Looking ahead, in 2026, we will continue to enhance job-specific competencies, enabling us to identify opportunities for more targeted training and development for our employees. We remain committed to providing training for supervisors to ensure they are equipped with the skills and knowledge needed to succeed in their roles, further strengthening our leadership development efforts.

### **Cybersecurity Risk Management and Governance** 
We have implemented and invested in, and will continue to implement and invest in, controls, procedures and protections (including internal and external personnel) that are designed to protect our systems, identify and remediate on a regular basis vulnerabilities in our systems and related infrastructure and monitor and mitigate the risk of data loss and other cybersecurity threats. We have engaged third-party consultants to conduct penetration testing and risk assessments. Our cybersecurity program is informed by the National Institute of Standards and Technology ("NIST") Cybersecurity Framework and measured by the Maturity and Risk Assessment Ratings associated with the NIST Cybersecurity Framework and the Capability Maturity Model Integration. Our cybersecurity risk management program is integrated into our overall enterprise risk management program, and shares common methodologies, reporting channels and governance processes that apply across the enterprise risk management program to other legal, compliance, strategic, operational, and financial risk areas.

Our cybersecurity risk management program includes:

&nbsp;&nbsp;&nbsp;&nbsp;• risk assessments designed to help identify material cybersecurity risks to our
 critical systems, information, products, services, and our broader enterprise IT and operational technology, or OT, environments;

• a security team principally responsible for managing (i) our cybersecurity risk assessment
 processes, (ii) our security controls, and (iii) our response to cybersecurity incidents;

• the use of external service providers, where appropriate, to assess, test, train or otherwise
 assist with aspects of our security controls;

• security tools deployed in the IT and OT environments for protection against, and monitoring
 for, suspicious activity;

• cybersecurity awareness training of our employees, including incident response personnel and
 senior management;

• cybersecurity tabletop exercises for members of our cybersecurity incident response team and
 legal department;

• a cybersecurity incident response plan that includes procedures for responding to cybersecurity
 incidents; and

• third-party risk management process for service providers, which may include diligence, assessments
 and/or contractual requirements, depending on each service provider's operational criticality and relative risk profile.

Our cybersecurity governance program is led by the Senior Vice President and Chief Information Officer, with support from the internal information technology department. The Senior Vice President and Chief Information Officer has over 20 years of technological leadership experience in the oil and gas industry, providing oversight of all information technology disciplines, including cybersecurity, networking, infrastructure, applications, and data management and protection. The Senior Vice President and Chief Information Officer and his team, which consists of individuals who hold designations as Certified Information Systems Security Professionals (CISSP), Certified Information Systems Auditors (CISA) and CompTIA Security+, are responsible for leading enterprise-wide cybersecurity strategy, policy, standards, architecture and processes. In addition, our cybersecurity incident response team is responsible for responding to cybersecurity incidents and is guided by our Computer Security Incident Response Plan. Progress and developments in our cybersecurity governance program are communicated to members of the executive team. Our management team takes steps to remain informed about and monitor efforts to prevent, detect, mitigate and remediate cybersecurity risks and incidents through various means, which may include briefings from internal security personnel; threat intelligence and other information obtained from governmental, public or private sources, including third-party consultants engaged by us; alerts and reports produced by security tools deployed in our IT and OT environments; and through reporting by employees and service providers. While our board of directors is ultimately responsible for enterprise-wide risk oversight, the board's committees assist the board in fulfilling its oversight responsibilities in certain areas of risk. In particular, the board's audit committee is responsible, among other things, for risk management relating to legal and regulatory requirements, including cybersecurity, which plays an integral role in our risk management strategy and continues to be an area of increasing focus for our board, the audit committee and our management team.

The audit committee of the board of directors receives quarterly updates from our Senior Vice President and Chief Information Officer on the status of our cybersecurity governance program, including as related to new or developing initiatives and any significant security incidents that may occur. Board members also receive presentations on cybersecurity topics from the Senior Vice President and Chief Information Officer as part of the board's continuing education on topics that impact public companies. Our cybersecurity governance program also includes processes to assess cybersecurity risks related to third-party services providers, suppliers and vendors.

### **Commitment to Community** 
Giving back to the communities where our employees live and in which we operate is part of our identity. We strongly believe these investments of time, money and compassion allow our employees to both experience and demonstrate the core values of our Company. We sponsor improvements in public education, participate in, and support, many community and national organizations and actively promote local groups who focus on the underserved and underprivileged. Below are a few examples of investments of time and money that we made in our Midland and Oklahoma City communities during 2025:

&nbsp;&nbsp;&nbsp;&nbsp;• Over 650 company employees volunteered a total of 5,739 hours.

• 140 company employees served as student mentors in our community throughout the year.

• Planted 200 trees in Midland public parks in underserved areas with irrigation for long-term
 support.

 the labs previously established at Legacy High School and Young Women's Leadership Academy, expanding the immersive
 (Virtual Reality) instruction method for students taking Anatomy and Physiology, Environmental Science and Neuroscience. Students
 learn from professors at prestigious universities in the multi-player room while also contributing to research and development
 on a collegiate level. Through this STEM Network, Diamondback has opened up 77 dual credit seats and has 287 students learning
 in an exciting, new educational space.

• Partnered with Midland Independent School District and their special services department to
 implement the Diamondback Rolling Baristas Program, aimed at providing valuable opportunities for students with disabilities
 to develop their work-readiness skills. Students come to Fasken Towers twice a week to serve coffee and refreshments while
 engaging with visitors and employees at our headquarters. This is our third year of implementation, and we have empowered
 150 students across our Midland community.

• Through our Diamondback Reading Buddy Program, Diamondback has partnered with three Midland
 elementary schools (including a bilingual campus) to read to 105 students that struggle with low literacy skills and/or language
 acquisition skills. We have over 50 volunteers who meet with students every other week to develop relationships and create
 a safe space where students can explore various books and experience the fun of reading.

• The Diamondback Robotics Mentorship Program is a partnership with a local secondary campus
 that focuses on building strong, collaborative robotics teams aligned with the FIRST Tech Challenge (FTC), and also help students
 strengthen teamwork and presentation skills critical for future leadership. Our teams have advanced to the Area Championship
 and State Championship and have won multiple awards at district and area competitions. Over 90% of participating students
 report increased confidence in pursuing STEM careers and alumni have returned as mentors in other Diamondback education programs,
 demonstrating the program's lasting impact.

• The Diamondback STEM Camp is a three-week camp held during the summer that served 77 young
 girls from 24 campuses across Midland. We had 89 Diamondback volunteers who contributed 1,346 hours of service to ensure the
 effectiveness of outreach, deepen a passion of STEM in our students and increase organizational pride.

• For the sixth year, donated "back to school" kits and more than 300 winter coats
 for every student at an underserved Oklahoma City Elementary School.

• Diamondback Energy volunteers in Oklahoma City partnered with the local education foundation
 in the spring semester to read to 50 students weekly in their local school district.

 secondary school for career mentorship. 60 volunteers from Diamondback provided year long career mentorship to students with
 a focus on college/ career readiness.

• Hosted the seventh annual First Responders Appreciation Luncheon for over 500 first responders.

• Donated approximately $3.6 million to local charities and philanthropic endeavors.

• Donated approximately $2.6 million through the Permian Strategic Partnership (PSP). The PSP
 was formed over five years ago by 17 (now 28) oil and gas companies to focus on making investments to help build superior
 educational programs, accessible housing, a supportive healthcare system, safer roads and a more skilled workforce throughout
 the Permian Basin.

&nbsp;&nbsp;&nbsp;&nbsp;• Partnered for the third year with the Midland Education Foundation to host the
 Teacher Winter Wishes Spectacular. During this event, 53 Diamondback volunteers were able to serve over 1,000 educators.

• Donated $5 million to the Midland Athletic Syndicate (MAS) for the construction of the MAS
 Sports Complex, a multi-purpose youth sports complex that will include an indoor field and courts used primarily for local
 sports and tournaments for youth.

• Donated $300,000 to the Texas A&M Engineering Academy at Midland College (MC). As a result
 of this investment, we have created the Diamondback DNA Mentorship Program which is a partnership with Texas A&M Engineering
 Academy and Midland College. We have 20 Diamondback mentors that meet with students in the academy every other week throughout
 the school year which supports student retention and determination of their engineering pathway.

• Donated $2.9 million to international non-profits and philanthropy to support Ukraine humanitarian
 needs. In 2022, Diamondback made a commitment to stand with the Ukrainian people by contributing $10 million toward humanitarian
 relief; the Company has achieved this commitment.

### **Political Contributions and Activities** 
We are committed to transparency about the Company's public policy advocacy efforts, political contributions and related activities. The safety, sustainability and corporate responsibility committee is responsible for reviewing and discussing with Company management our public policy advocacy efforts and annually reviews the activities of our political action committees (each, a "PAC"), all political contributions made with corporate funds and membership dues paid to 501(c)(6) U.S. based trade associations (including any portion of dues used for lobbying activities). In an effort to encourage employee participation, we have initiated a matching program whereby eligible employees, in the case of the Company's sponsored state PAC, and eligible employees and their spouses, in the case of the Company's sponsored federal PAC and a Company chosen PAC sponsored by a 501(c)(6) U.S. based federal trade association, who are contributing to the specified PAC can request that that Company make a matching donation in accordance with the Company's matching guidelines and subject to the limits thereof for an aggregate match not to exceed $30,000 per employee per year. The matching program is broadly available to all eligible employees, including executive officers, on the same terms. All employee contributions to these PACs are not tax deductible and are not reimbursed by the Company.

We published our 2025 Corporate Political Contributions Disclosure Report in February 2026 on our website. In 2025, the Center for Political Accountability assessed our political contribution disclosures for its annual CPA-Zicklin Index of Corporate Political Disclosure and Accountability and designated the Company a trendsetter score of 90.0%.

The Company evaluates its Corporate Political Contribution Disclosure Report annually, and we encourage you to review our 2025 Corporate Political Contributions Report and our Policy Governing Political Contributions and Activities, which are both available on our website under the "Investors—Corporate Governance" caption.

### **Moving Forward** 
We are proud of what we have been able to accomplish as a company and believe our achievements show a serious and growing commitment, to our evolving corporate responsibility. We are resolved to live our core values of leadership, integrity, excellence, people and teamwork and we will continue to strive for continuous improvement in the years ahead.

### **Stockholder Outreach and 2025 "Say-On-Pay" Advisory Vote** 
The compensation committee carefully reviews our executive pay programs and focuses on emphasizing pay for performance in making annual compensation decisions. The compensation committee values the insight we receive from our stockholder outreach and from our annual say-on-pay advisory vote on executive compensation. In 2025, approximately 97% of votes cast by our stockholders were in favor of our say-on-pay proposal. Although this vote demonstrates substantial support of our executive compensation programs, representatives of our board and management team continued to undertake stockholder engagement efforts to, among other things, solicit stockholder input on our executive compensation program and ensure ongoing stockholder support of our executive compensation programs. However, no specific changes were made to our executive compensation program as a result of the 2025 say-on-pay vote. During 2025, we solicited feedback on our executive compensation programs, environmental and safety matters and other important corporate governance issues. For a discussion of our stockholder engagement and actions that we have taken in response to stockholder feedback, see "Corporate Governance Matters—Stockholder Engagement" on page 31.

## **—** **EXECUTIVE COMPENSATION POLICY AND OBJECTIVES** 

### **Executive Compensation Objectives** 
Our executive compensation philosophy is guided by several key principles described below:

---

| | | |
|:---|:---|:---|
| **Our Goals** | • | Our goals are to attract, retain, and motivate our executive team and our organization to deliver results against our short-term and long-term objectives in a principled way, with prudent risk-taking, and alignment with our stockholders. |
| **Pay for Performance** | • | A majority of total compensation to our executive officers is at-risk, performance-based compensation, including both long-term performance-based equity awards and short-term performance-based cash incentive awards. |
|  | • | Our long-term equity awards include performance-based awards based on relative TSR, as modified by an absolute TSR modifier. For awards made in 2025, the Company's TSR performance peer group included the S&P 500 and XOP Index (weighted twice) to account for performance against the broader market and industry (in addition to a limited set of similarly situated upstream oil and gas companies). |
|  | • | Annual cash incentive awards are based on rigorous operational, financial and environmental and safety performance metrics that align with our strategic priorities and are entirely quantitative. |
|  | • | Our compensation structure motivates executives and our employees to deliver outstanding financial performance and meet or exceed general and specific business, operational and individual objectives, and progress towards our long-term strategic goals. |
| **Alignment with Stockholder Interests** | • | We provide a majority of the total compensation to our executive officers in Company equity, thus ensuring alignment of interests between our executives and our stockholders, and driving alignment of goals, efforts, and results throughout the organization. |
| **Market-Based Competitive Compensation that Attracts, Motivates and Retains Talent** | • | Our compensation programs are competitive, with compensation and incentive levels that are relevant to the market and our industry, which enhances our ability to attract, motivate and retain knowledgeable and experienced senior management talent necessary to manage our complex organization and responsibly deliver energy to the marketplace. |
| **Risk Management Principles** | • | Our compensation committee consists entirely of independent directors who engage an external, independent compensation consultant to assist in constructing an executive compensation program that aligns with good governance practices and prevailing market trends. |

---

### **The Role of the Compensation Committee** 
Our compensation committee oversees and approves our executive compensation program and establishes our overall compensation philosophy and strategy. The compensation committee, with the assistance of its external, independent compensation consultant, determines the mix of compensation, both among short-term and long-term components and cash and equity components, to establish compensation that it believes is appropriate for each of our NEOs. Representatives of the compensation committee may also participate in the Company's stockholder engagement efforts to, among other things, solicit stockholder input on our executive compensation program and ensure ongoing stockholder support of our executive compensation programs. In making compensation decisions with respect to each element of compensation, the compensation committee considers numerous factors, including:

&nbsp;&nbsp;&nbsp;&nbsp;• aligning the compensation of our executives with the performance of the Company
 on both a short-term and long-term basis;

• achievement of individual and Company performance goals and other expectations relating to
 the executive's position;

• a comparison of the individual to other executives within the Company with similar levels
 of expertise and experience;

• the individual's role with us and the compensation paid to similar executives at comparable
 companies;

• the individual's particular background and circumstances, including training and prior
 relevant work experience and unique industry skills;

• the demand for the individual's specific expertise and experience;

• succession planning and retention considerations; and

• recommendations from Messrs. Stice and Van't Hof (but not with respect to their own
 compensation).

***DIAMONDBACK ENERGY, INC.*** • 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **47**

[Back to Contents](#toc)

The compensation committee seeks to design a total compensation package for our NEOs that drives performance, rewards contributions in support of our business strategies and attracts, motivates and retains high quality talent with the skills and competencies our industry requires. The compensation committee seeks to balance these goals by designing our compensation policies and programs to encourage and reward prudent business judgment over the long-term by offering both time-based and performance-based long-term incentive (LTI) awards, setting meaningful performance criteria and targets for incentive compensation, and offering competitive base salaries. The compensation committee believes that this combination promotes performance and retention while also mitigating the risk of executives and management-level employees engaging in excessive risk-taking.

### **The Role of Management** 
In 2025, Messrs. Stice and Van't Hof evaluated executive and Company performance for the prior year and made recommendations to the compensation committee regarding the annual base salaries, annual incentive compensation plan target award percentages and LTI awards under the Equity Incentive Plan for the executive officers, including the NEOs (other than with respect to their own compensation). Mr. Stice also made recommendations to the compensation committee regarding the annual base salary, annual incentive compensation plan target award percentage and LTI award under the Equity Incentive Plan for Mr. Van't Hof. The Company's Human Resources and Legal departments also assist the compensation committee and its independent compensation consultant in gathering the information needed for their respective reviews of the Company's executive compensation program. While the compensation committee considers Messrs. Stice and Van't Hof's evaluation of the other executive officers and their recommendations as to compensation for the other executive officers, the compensation committee ultimately determines the compensation of each executive officer, including each NEO. No member of the management team has a role in determining his or her own compensation.

The compensation committee evaluates Mr. Van't Hof's performance and compensation based on his leadership role, his individual performance and the Company's performance measured against the metrics described in this compensation discussion and analysis, and his total compensation package is ultimately determined by the compensation committee.

### **The Role of the Compensation Consultant** 
Our compensation committee annually retains, at the Company's expense, an external, independent compensation consultant to assist with executive and non-employee director compensation matters. The compensation committee retained Meridian as its independent compensation consultant in connection with its evaluation of executive compensation for 2025.

The compensation committee reviewed the independence of Meridian during the applicable engagement period and determined that there were no conflicts of interest as a result of the compensation committee's engagement of such consultant. The compensation committee continues to evaluate the independence of its compensation consultant on an ongoing basis. Meridian did not provide any services to the Company during 2025 other than related to executive and director compensation.

The compensation committee has sole authority to hire and terminate its independent compensation consultant, and the independent compensation consultant reports only to the compensation committee. From time to time, Meridian contacts the Company's executive officers for information necessary to fulfill its assignment and prepares reports for and on behalf of the compensation committee that certain executive officers also receive.

## **—** **COMPETITIVE BENCHMARKING** 

### **Role of Benchmarking in Determining Executive Compensation for 2025** 
In general, the compensation committee uses competitive market compensation data provided by Meridian, information gathered from Meridian's proprietary E&P Compensation Survey, public filings of peer companies, supplemental general industry reference data for cross-industry roles and discussions with Messrs. Stice and Van't Hof to inform its decisions about overall compensation opportunities and specific compensation elements. The compensation committee considers these compensation elements and total compensation benchmarks of peer companies and the broader U.S. market. Next, the compensation committee applies judgment and discretion in establishing targeted pay levels, taking into account not only competitive market data, but also factors such as Company and individual performance, scope of responsibility, critical needs, skill sets, leadership potential, and succession planning.

***DIAMONDBACK ENERGY, INC.*** • 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **48**

[Back to Contents](#toc)

Further, in considering changes to the 2025 executive compensation packages, the compensation committee evaluated, among other things, aspects of executive compensation in general, market data and competitive analysis provided by Meridian, the Company's 2025 and multi-year performance and growth, our executives' individual contributions to such performance and growth, compensation alignment with future performance and stockholder value creation, performance-qualified equity awards, retention considerations, market alternatives for our executives, input obtained from our stockholder outreach efforts and the recommendations of Messrs. Stice and Van't Hof (other than with respect to their own compensation).

### **Our 2025 Benchmarking Compensation Peer Group** 
In structuring our compensation policies and programs, the compensation committee considers the compensation practices of peer companies consisting of independent oil and gas E&P companies and may also review compensation data from the oil and natural gas industry, any relevant compensation surveys and guidance from the compensation consultant. The compensation committee considers and may make changes to the companies included in our compensation peer group, primarily based on industry segment, and measures of size such as enterprise value, market capitalization and assets, after discussing such considerations with management and Meridian. The compensation committee worked closely with Meridian to construct a sufficiently sized peer group that accounted for the Company's recent growth, including its recent acquisition of Endeavor, and the significant industry M&A activity in 2023 and 2024. In doing so, the compensation committee elected to expand the Company's peer group to include similarly sized companies from other sectors within the oil and gas industry and remove peers that were acquired or whose relative size no longer sufficiently aligned with the Company.

In its review of the compensation peer group for 2025, the compensation committee considered pertinent financial measures for each company as provided by Meridian, including enterprise value and market capitalization as of November 7, 2024, and assets as of the quarter ended September 30, 2024, as shown (in millions) in the table below:

---

| | | | |
|:---|:---|:---|:---|
|  | **Enterprise Value** | **Market Capitalization** | **Assets** |
| **Peer Group 50<sup>th</sup> Percentile** | $69119 | $45319 | $43075 |
| **Diamondback Energy, Inc.** | $70300 | $56496 | $65747 |

---

The benchmarking compensation peer group used in Meridian's study, which served as reference for making compensation decisions for 2025, consisted of the following 13 companies.

---

| | |
|:---|:---|
| APA Corporation | Expand Energy Corporation |
| Cheniere Energy, Inc. | Occidental Petroleum Corporation |
| ConocoPhillips Company | Ovintiv Inc. |
| Coterra Energy Inc. | Phillips 66 |
| Devon Energy Corporation | SLB Limited |
| EOG Resources | The Williams Companies |
| EQT Corporation |  |

---

Meridian provided competitive data for similarly situated executives at these compensation peer group companies, focusing on salary, annual incentive opportunity and LTI opportunity, and analyzing how these elements of compensation compare to the elements of compensation afforded to our executive officers, including the NEOs.

For cross-industry roles (i.e., CFO, General Counsel), Meridian also provided the compensation committee with supplemental data from a private survey of large, cross-industry companies for consideration.

As described below, to assess our relative TSR performance in the performance-based restricted stock unit awards granted to our NEOs, the compensation committee utilizes a peer group that is limited to similarly sized upstream oil and gas companies and also includes the S&P 500 (weighted once) and XOP Index (weighted twice).

## **—** **2025 COMPENSATION PROGRAM DESIGN AND STRUCTURE** 
During 2025, the Company's executive compensation program consisted of four primary components including both fixed and variable, at-risk elements, as shown below.

---

| | | | |
|:---|:---|:---|:---|
|  | **Direct**<br> **Compensation Element** | **Form of Compensation** | **Purposes and Alignment**<br> **with Long-Term Stockholder Interests** |

## **—** **EXECUTIVE COMPENSATION PROGRAM ELEMENTS** 
Our compensation committee determines the mix of compensation, both among short-term and long-term compensation and cash and non-cash compensation, to establish total compensation packages that it believes are appropriate for each of our NEOs. While emphasizing pay for performance, the compensation committee believes that the mix of base salary, performance-based annual incentive bonus awards based on pre-established financial, operational and environmental and safety performance targets, performance-based LTI equity awards, time-based LTI equity awards, and the other benefits that are available to our NEOs will accomplish our overall compensation objectives. We believe that these elements of compensation create competitive, retentive and compelling compensation opportunities and also align our NEO's interests with long-term stockholder interests.

![](lfang2026_def14ax54x1.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *CEO compensation in this graph is for Mr. Stice, who served as our CEO until May 2025. Each of these pay mix illustrations consists of the annual base salary, annual incentive bonus earned and the grant date fair value of the performance-based and time-based equity awards granted in 2025. These pay mix illustrations exclude amounts listed in the column titled "All Other Compensation" in the Summary Compensation Table set forth on page 66.* 

**LETTER AGREEMENT WITH EXECUTIVE CHAIRMAN**

On February 20, 2025, the Company and Mr. Stice entered into a letter agreement specifying the terms on which he will serve as Executive Chairman. The letter agreement provides, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;• Mr. Stice will serve as Executive Chairman until the Company's 2026 Annual Meeting.

• Mr. Stice's annual base salary was adjusted down to $900,000 and his target annual bonus opportunity for 2025 was
 set at 150%.

For further information on the Letter Agreement with Mr. Stice, see page 64.

### **Pay for Performance Driven Compensation Structure** 
The following describes each element of our executive compensation program, which we use to meet our compensation objectives discussed above.

#### **Base Salary** 
The compensation committee evaluates our NEOs' base salaries together with other components of their compensation to ensure equitable total compensation in line with our overall compensation philosophy and market practices in our compensation peer group, our industry in general, and considering other general industry benchmarks for executive roles which are not industry specific. In setting our NEOs' base salaries and incentive targets for 2025, the compensation committee considered, among other factors:

&nbsp;&nbsp;&nbsp;&nbsp;• the market and compensation peer group data included in the study conducted by
 Meridian, the compensation committee's independent compensation consultant for 2025, discussed above;

• the recommendations of Messrs. Stice and Van't Hof with respect to the base salaries
 for other NEOs;

• the complexity of the individual's role within the Company;

• the individuals' expertise, experience, rarity of skill, and potential for advancement;

• if the executive was promoted or identified in our succession planning; and

• individual performance, leadership and contribution toward the Company's achievement
 of certain financial, operational and environmental and safety metrics discussed in this compensation discussion and analysis.

The compensation committee approved an increase to our other NEOs' annual base salaries for 2025 as compared to 2024 based on Company and individual performance and competitive benchmarks for their respective roles and responsibilities. Based on the foregoing considerations, the compensation committee set the following annual base salaries for our NEOs effective as of February 23, 2025:

---

| | | |
|:---|:---|:---|
| **Name** | **2025 Base Salary** | **2024 Base Salary** |
| **Travis D. Stice<sup>(1)</sup>** | $1500000 | $1400000 |
| **Kaes Van't Hof<sup>(2)</sup>** | $800000 | $700000 |
| **Jere W. Thompson III** | $550000 | $500000 |
| **Teresa L. Dick** | $550000 | $525000 |
| **Daniel N. Wesson** | $700000 | $650000 |
| **Matt Zmigrosky** | $700000 | $630000 |

---

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *In accordance with the letter agreement with Mr. Stice, effective as of the Company's 2025 Annual Meeting in May 2025, Mr. Stice's base salary was adjusted to be $900,000.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(2)* *Effective as of Mr. Van't Hof's promotion to Chief Executive Officer as of the Company's 2025 Annual Meeting in May 2025, Mr. Van't Hof's base salary was adjusted to be $1,300,000.* 

#### **Performance-Based Annual Incentive Bonus** 
**2025 PERFORMANCE BONUS**

Performance bonuses to our NEOs for 2025 were granted under our Executive Annual Incentive Compensation Plan (the Annual Incentive Plan). The Annual Incentive Plan is designed to provide an incentive to our executive officers to contribute to the growth, profitability and increased value of the Company. The Annual Incentive Plan is focused on achievement of annual objectives and goals, determined at the beginning of each calendar year. Participants may earn a pre-determined percentage of base salary for the achievement of specified goals (performance targets). The payout opportunity varies for performance above and below the pre-established target performance levels. For a more detailed description of the Annual Incentive Plan, see "Other Significant Compensation and Benefit Plans, Policies and Practices—Annual Incentive Plan" beginning on page 62 of this proxy statement.

With respect to each annual performance period, the compensation committee specifies the performance factors and the performance target levels applicable to each award. Performance targets may include a level of performance below which no payment will be made and levels of performance at which specified percentages of the award will be paid as well as a maximum level of performance above which no additional award will be paid.

[Back to Contents](#toc)

Below is a simple illustration of the design of Diamondback's 2025 Performance Bonus:

![](lfang2026_def14ax56x1.jpg)

For 2025, the compensation committee did not change the annual incentive target percentages for Ms. Dick or Messrs. Stice, Wesson or Zmigrosky. The compensation committee increased the annual incentive target percentage from 80% to 90% for Mr. Thompson in connection with his promotion to Executive Vice President and Chief Financial Officer in February 2025. In connection with Mr. Van't Hof's promotion to Chief Executive Officer as of the Company's 2025 Annual Meeting, Mr. Van't Hof's annual incentive target percentage increased from 100% to 150%.

Each year, the compensation committee, advised by its independent compensation consultant and informed by feedback received during the Company's substantial stockholder engagement efforts, undertakes a thorough and rigorous process to review each element of the Company's Annual Incentive Plan scorecard. The compensation committee's desire to be proactive in implementing thoughtful changes to our compensation practices has allowed the compensation committee to continually construct a scorecard that is directly responsive to stockholder feedback and is intended to incentivize our management team in ways that translate to stockholder value creation and encourage responsible governance practices. This strategy is reflected in the evolution of the scorecard over the last decade during which the compensation committee proactively:

&nbsp;&nbsp;&nbsp;&nbsp;**(i)** eliminated production and reserves growth metrics;

**(ii)** added a return on average capital employed metric to our performance factors;

**(iii)** added specific, measurable environmental and safety performance targets; and

**(iv)** included more performance factors focused on financial returns and increased the weighting of such performance factors while reducing
the weighting of performance factors related to costs and capital efficiency.

When constructing the Annual Incentive Plan scorecard for 2025, the compensation committee again reviewed significant data from its independent compensation consultant, incorporated stockholder feedback and reviewed the performance factors in light of the Company's strategic objectives for 2025. The compensation committee also observed the positive trend of consistent stockholder support for the Company's executive compensation programs, with stockholders voting to approve the Company's say-on-pay proposal at a rate of at least 95% for each of the past 4 years. Accordingly, the framework for the 2025 Annual Incentive Plan scorecard was largely unchanged. The compensation committee elected to maintain the same categories of performance factors and the same weightings for each performance factor, with the few adjustments described below.

First, the compensation committee removed the total gas flaring performance factor from the scorecard (previously weighted at 2.5%) and maintained the gas flaring related to Company operations performance factor and increased the weighting from 2.5% to 5%. Upon further evaluation by the compensation committee, total gas flaring comprises the majority of the Company's Scope 1 GHG intensity outcome and is largely driven by the actions of third parties that are out of the Company's control. As Scope 1 GHG intensity is separately measured in the current scorecard framework, the compensation committee elected to narrow the gas flaring performance factor to Company operations and set rigorous performance targets for 2025 that account for the integration of the Endeavor assets.

Second, the compensation committee approved slight modifications to its water usage performance factor given the Company met and exceeded its prior water recycling target. For 2025, the performance factor was calculated by taking total barrels of non-fresh water used, divided by total barrels of water used in operations.

When establishing the 2025 performance levels for each performance factor under the Annual Incentive Plan, the compensation committee reviewed, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;• our performance trends over a multi-year period;

• our capital budget, business plan and annual guidance;

• execution challenges expected due to perceived inflationary pressures;

• the effects of the ongoing integration of the Endeavor assets following the closing of the Endeavor Merger in September
 2024;

• capital requirements; and

• the appropriateness and rigorousness of the target, threshold and maximum performance levels for each performance factor.

 

***DIAMONDBACK ENERGY, INC.*** • 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **53**

[Back to Contents](#toc)

Specifically with respect to the performance targets for each metric comprising the environmental and safety performance factor, such performance targets were set for each metric taking into account multiple considerations, including a review of our performance trends over a multi-year period, benchmarking considerations relative to peer performance over a multi-year period and the significant increase in the scope of consolidated assets and employees following the Endeavor Merger.

Taking the foregoing into account, the performance factors and levels listed in the table below were established by the compensation committee in February 2025. Considering the Company's capital budget, business plan and annual guidance for 2025, the compensation committee set target performance levels that the compensation committee believed were rigorous and appropriate based on the Company's expected plans for 2025. Additionally, the compensation committee intended to set target performance levels that were competitive with the metrics of the best operators in our compensation peer group in each respective category and were responsive to feedback from our stockholders.

The performance goals shown below align with how management views our success and how stockholders evaluate our financial, operating and environmental and safety performance, both on a standalone basis and relative to our peers and the broader energy industry.

In February 2026, the compensation committee reviewed and certified the Company's performance in relation to the pre-established performance goals and targets for 2025, which are set forth below:

#### **Long-Term Equity Incentive Compensation** 
We believe providing our NEOs the opportunity to be awarded stock and stock-based awards offers the best approach to achieving our compensation goals and aligns the interests of our executive officers with those of our stockholders. To achieve this purpose, our board of directors adopted, and our stockholders approved, the 2021 Amended and Restated Equity Incentive Plan (Equity Incentive Plan). The purpose of the Equity Incentive Plan is to enable us, and our affiliates, to attract and retain the services of the types of executives, employees, consultants and directors who will contribute to our long-term success and to provide incentives that will be linked directly to increases in share value that will benefit our stockholders. The Equity Incentive Plan provides a means by which eligible recipients of awards may be given an opportunity to benefit from increases in value of our common stock through the granting of equity awards. The terms of awards granted in 2025 to our NEOs under the Equity Incentive Plan are described in more detail below.

**MARCH 2025 AND MAY 2025 DIAMONDBACK PERFORMANCE-BASED AND TIME-BASED AWARDS**

In March 2025, the compensation committee granted our NEOs three-year performance-based restricted stock units and time-based restricted stock units, in each case under the Equity Incentive Plan, in the amounts shown below. In 2025, the compensation committee established 2025 Target LTI awards based on a review of market data from its independent compensation consultant, Company and individual performance, and the prevailing industry environment. Consistent with the compensation committee's focus on giving more weight to the performance component of our executive compensation, the 2025 performance-based equity award granted to each NEO represented 60% of the total 2025 LTI award, with the time-based component of such award representing 40% of the total 2025 LTI award. In May 2025, the compensation committee granted a supplemental award to Mr. Van't Hof in connection with his promotion to Chief Executive Officer as detailed below.

| **Travis D. Stice** | 50564 | 60% | 33709 | 40% | $13000000 |
| **Kaes Van't Hof<sup>(4)</sup>** | 31412 | 60% | 20941 | 40% | $7750000 |

| **Matt Zmigrosky** | 11085 | 60% | 7390 | 40% | $2850000 |

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *The three-year performance-based restricted stock units are for the performance period from January 1, 2025 through December 31, 2027. Each NEO is also entitled to dividend equivalent rights on such NEO's unvested performance-based restricted stock units at target.* 

*(2)* *Subject to footnote 4 below, time-based restricted stock units of which one-third of the award vested on March 1, 2025, with the remaining time-based restricted stock units vesting in two substantially equal annual installments beginning on March 1, 2026. Each NEO is also entitled to dividend equivalent rights on such NEO's unvested time-based restricted stock units.* 

*(3)* *Subject to footnote 4 below, the aggregate number of performance-based and time-based restricted stock units for each NEO for 2025 was calculated by dividing the targeted value of the total LTI award for each NEO indicated in the table by $154.26 per share, representing the average closing price per share of our common stock on The Nasdaq Global Select Market for the five trading days immediately preceding the last trading day in February 2025, and allocated 60% to the performance-based restricted stock units and 40% to the time-based restricted stock units.* 

*(4)* *On March 1, 2025, Mr. Van't Hof was granted 11,020 time-based restricted stock units and 16,531 performance-based stock units with an aggregate targeted value of $4,250,000. One-third of the time-based restricted stock units vested on March 1, 2025, with the remaining time-based restricted stock units vesting in two substantially equal installments beginning on March 1, 2026. On May 21, 2025, in connection with his promotion to Chief Executive Officer, Mr. Van't Hof was granted an additional equity award consisting of 9,921 time-based restricted stock units and 14,881 performance-based stock units with an aggregate targeted value of $3,500,000. The aggregate number of performance-based and time-based restricted stock units for this grant was calculated by dividing the targeted value of the total LTI award by the average closing price per share of our common stock on The Nasdaq Global Select Market for the five trading days immediately preceding the effective date of Mr. Van't Hof's promotion to Chief Executive Officer. One-third of the time-based restricted stock units vested on May 21, 2025, with the remaining time-based restricted stock units vesting in two substantially equal installments on each of March 1, 2026 and March 1, 2027. The three-year performance-based restricted stock units are for the performance period from January 1, 2025 through December 31, 2027.* 

The performance-based restricted stock units are subject to the performance of our total stockholder return relative to our TSR performance peer group set forth in the table below for the applicable performance period. Additionally, the number of performance-based restricted stock units that would otherwise vest is further adjusted by the absolute TSR modifier illustrated below that reduces payouts upon negative absolute TSR, and increases payouts when the absolute TSR is greater than 15%. No awards vest if the relative total stockholder return (prior to any adjustment required by application of the absolute TSR modifier) falls below the 25<sup>th</sup> percentile. The performance-based restricted stock units are also subject to satisfaction of continuous service requirements.

Target grant vesting percentage is expressed as a percentage of the target number of performance-based restricted stock units granted and, after being adjusted by the applicable absolute TSR modifier, may result in a settlement up to a maximum grant equal to 250% of the target number of performance-based restricted stock units granted.

These awards were designed to incentivize our NEOs to continue to contribute to the Company's performance at the top of its TSR performance peer group, similar to the Company's performance in prior periods. In addition, the time-based restricted stock unit awards were designed to promote retention of our NEOs who are frequently pursued by industry competitors and private equity groups.

**2025 TSR PERFORMANCE PEER GROUP**

The 2025 TSR performance peer group, which was approved by the compensation committee and will be used to determine the total stockholder return percentile in the 2025 performance-based restricted stock unit awards granted in March 2025 to the NEOs, consisted of the following nine members in addition to the Company.

**MARCH 2025 VIPER PERFORMANCE-BASED AWARDS**

Under the terms and conditions of Viper's 2024 Long-Term Incentive Plan (the "Viper LTIP"), Viper's board of directors or its compensation committee, established in March 2024, may, from time to time, grant equity awards under the Viper LTIP to our executive officers and other employees who perform services for Viper. In order to motivate and incentivize our executive officers who perform such services for Viper under the Services and Secondment Agreement and further align their interests with those of Viper's stockholders, in March 2025, Viper's board of directors and compensation committee granted performance-based restricted stock unit awards to our NEOs other than Mr. Stice under the Viper LTIP in the amounts shown below.

*(2)* *The aggregate number of performance-based and time-based restricted stock units for each NEO for 2025 was calculated by dividing the targeted value of the total LTI award for each NEO indicated in the table by $46.17 per share, representing the average closing price per share of Viper's common stock on The Nasdaq Global Select Market for the five trading days immediately preceding the last trading day in February 2025.*

The performance-based restricted stock units are subject to the performance of our total stockholder return relative to Viper's TSR performance peer group for the applicable performance period. Additionally, the number of performance-based restricted stock units that would otherwise vest is further adjusted by an absolute TSR modifier that reduces payouts upon negative absolute TSR, and increases payouts when the absolute TSR is greater than 15%. No awards vest if the relative total stockholder return (prior to any adjustment required by application of the absolute TSR modifier) falls below the 25<sup>th</sup> percentile. The performance-based restricted stock units are also subject to satisfaction of continuous service requirements. For more information regarding these performance-based restricted stock unit awards, please see Viper's proxy statement filed with the SEC in connection with its 2026 annual meeting of stockholders.

**VESTING OF 2023 PERFORMANCE-BASED AWARDS**

In February 2026, the compensation committee certified the attainment of the pre-established performance goals with respect to performance-based restricted stock units granted to our NEOs in March 2023, which awards were subject to the satisfaction of certain total stockholder return performance conditions relative to our TSR performance peer group for the performance period commencing on January 1, 2023 and ending on December 31, 2025, and continuous service requirements.

The compensation committee certified that, based on publicly available information:

&nbsp;&nbsp;&nbsp;&nbsp;**(i)** our total stockholder return for the above-referenced performance period
 was in the 82<sup>nd</sup>percentile of the applicable TSR performance peer group resulting in a target vesting percentage
 of 200%;

**(ii)** the cumulative absolute total stockholder return percentage for the above-referenced
 performance period was approximately 27% (approximately 8% on an annualized basis), resulting in no further adjustment by
 the absolute TSR modifier and a resulting vesting percentage of 200% of the target number of restricted stock units granted
 to the NEOs; and

**(iii)** the applicable performance target and other material terms of such performance-based restricted
 stock unit awards were achieved at such levels for the above-referenced performance period.

Acquired companies were not excluded from the relative comparison during the performance period, and the total stockholder return for such companies was measured assuming the performance period ended for each such company at the announcement of the applicable acquisition.

In connection with reaching these performance goals, each of the 2023 performance-based restricted stock unit awards received by Messrs. Stice, Van't Hof, Thompson, Wesson and Zmigrosky and Ms. Dick vested at 200% of the target, resulting in the issuance of the shares of the Company's common stock underlying the 2023 performance-based restricted stock units to these NEOs in March 2026 as follows:

## **OTHER SIGNIFICANT COMPENSATION AND BENEFIT PLANS, POLICIES AND PRACTICES** 

### **Senior Management Severance Plan** 
Effective February 20, 2020, we adopted the Diamondback Energy, Inc. Senior Management Severance Plan, which was (i) amended and restated effective February 21, 2022, to provide for adjustments to severance benefits in connection with certain executive promotions and related title changes and (ii) revised to provide for certain clarifying amendments effective February 11, 2024 and effective April 6, 2025 (as so amended and restated, the severance plan). We entered into a participation agreement thereunder with each of our NEOs. Pursuant to the participation agreements, the benefits under the severance plan replace any prior employment agreement with each of our NEOs. The severance plan also covers other eligible executives who are selected to participate and replaces any employment agreement they may have had. The severance plan provides a uniform framework for certain severance and change in control benefits that are consistent with market practices and is described in more detail below.

#### **Payments and Benefits Unrelated to a Change in Control** 
In the event that the employment of a participating executive is terminated by us other than for "cause" (and not by reason of death or disability) or if the participant terminates his or her employment for "good reason" (in each case as defined in the severance plan), in addition to any accrued but unpaid base salary or unreimbursed business expenses payable in accordance with the requirements of applicable law, the participant is entitled to receive severance benefits consisting of:

&nbsp;&nbsp;&nbsp;&nbsp;**(i)** an amount, if any, equal to the bonus that would be payable for services attributable
 to a completed prior year performance period that has not been paid under the terms of the Annual Incentive Plan or any successor annual
 cash incentive plan or program;

**(ii)** base salary continuation for a specified number of months: 24 months of base salary
 for the Chief Executive Officer; 18 months for Executive Vice Presidents; 15 months for Senior Vice Presidents and 12 months for
 Vice Presidents;

**(iii)** a pro-rated target annual cash bonus for the year of termination (based on the
 number of days employed during the year of termination);

**(iv)** reimbursements for the cost of up to 18 months of premiums for COBRA group health
 continuation coverage; and

**(v)** the vesting or forfeiture, as applicable, of each outstanding unvested equity-based compensation award
 granted by us or our affiliates in accordance with the terms of the applicable equity award agreement.

Mr. Stice's participation agreement includes terms that are intended to maintain certain benefits under his prior employment agreement and are consistent with prior public disclosure that require each equity award granted to Mr. Stice to become 100% vested upon an eligible termination, and in the case of outstanding performance-based equity awards to vest at the maximum level under the equity award agreement, and be settled within ten business days.

#### **Severance Benefits Related to a Change in Control** 
In the event that employment of a participant is terminated by us other than for "cause" (and not by reason of death or disability) or if the participant terminates his or her employment for "good reason," in either case within the two year period (protection period) immediately following the consummation of a change in control (as defined in the severance plan), the participant will be entitled to the benefits described above, except that the salary continuation described in clause (ii) will be replaced by a lump sum cash payment equal to a multiple of the participant's annual base salary plus the greater of such participant's target bonus and the participant's average bonus for the preceding three years (3.0x for the Chief Executive Officer, 2.5x for Executive Vice-Presidents, 2.25x for Senior Vice-Presidents and 2.0x for Vice-Presidents).

#### **Severance Benefits Related to Death or Disability** 
The severance plan also provides the same benefits described in clauses (i), (ii), (iii) and (v) above (but not clause (iv)) in the event that a participant dies or becomes disabled (as defined in the severance plan) while employed by us. Mr. Stice's participation agreement includes terms that are intended to maintain certain benefits under his prior employment agreement and are consistent with prior public disclosure that require the Company to pay 100% of the premiums to continue the group health plan continuation coverage under COBRA for Mr. Stice (in the event of his disability) and his spouse's and any of his eligible dependents (in the event of his death or disability).

#### **Release and Restrictive Covenants** 
The payment of any benefits under the severance plan is conditioned on the participant's (or if applicable, the participant's personal representative's or estate's) execution of a waiver and general release of claims. The severance plan also includes certain covenants restricting (i) competition with Diamondback and its subsidiaries, (ii) solicitation or hire of employees or agents of Diamondback and its subsidiaries and (iii) interference with business relationships of Diamondback and its subsidiaries with third parties, which covenants apply, in each case, during the period of the participant's employment with the Company and for a period of one year (or such shorter period described below) following termination of employment (collectively, the restricted period). The severance plan also includes indefinite confidential information and non-disparagement covenants in favor of Diamondback. If a participating executive resigns employment on a basis that is not eligible for severance benefits, the Company can elect to apply these restrictive covenants for a monthly period selected by the Company not to exceed 12 months and receive a waiver and release by payment of an amount equal to one-twelfth of the participant's annualized base salary plus target annual bonus for each month the restrictive covenants will apply, and such amount will be paid on a pro-rated basis on a regularly scheduled payroll date during such restricted period following the termination date. Notwithstanding the foregoing restrictions, in the event the participant's employment is terminated by the Company without cause or by the participant for good reason during the protection period or due to the participant's death or disability, the restrictions on competition with Diamondback and its subsidiaries and on interference with their business relationships with third parties will end on the date of such participant's termination of employment.

We believe that these severance benefits provide the same type of income transition protections that were provided to our executives under their prior employment agreements, offer letters or similar agreements. The severance plan's provisions are intended to attract and retain qualified executives that could have job alternatives that may appear to them to be less risky absent these arrangements. We believe that the enhanced severance benefits resulting from terminations related to a change in control transaction are in the interest of our stockholders because they provide an incentive for executives to continue to help successfully execute such a transaction from its early stages through consummation. We also believe that these benefits provide important protection to our NEOs, are consistent with the prior employment protections and the practices of peer group companies and are appropriate for the attraction and retention of executive talent.

### **Viper Energy, Inc. 2024 Amended and Restated Long-Term Incentive Plan** 
We provide personnel and general and administrative services to our publicly traded subsidiary Viper, including the services of the executive officers and other employees, pursuant to the Services and Secondment Agreement, dated as of November 2, 2023, and effective as of November 13, 2023. Under the terms and conditions of the Viper LTIP adopted by the stockholders of Viper, Viper's board of directors or its compensation committee, established in March 2024, may, from time to time, grant equity awards under the Viper LTIP to our executive officers and other employees who perform services for Viper. Similar to the Viper LTIP 2024 awards, to motivate and incentivize our executive officers who perform such services for Viper under the Services and Secondment Agreement and further align their interests with those of Viper's stockholders, in March 2025, Viper's compensation committee granted performance-based restricted stock unit awards to Viper's executive officers under the Viper LTIP that are subject to the satisfaction of certain Viper stockholder return performance conditions relative to Viper's TSR performance peer group during the three-year performance period. For additional information regarding such performance-based awards under the Viper LTIP, see "Stock Ownership—Holdings of Officers and Directors" and related footnotes beginning on page 85.

### **Benefits and Perquisites** 
Consistent with our compensation philosophy, our compensation committee provides benefits to our executives that are substantially the same as those currently being offered to our other employees, including health insurance, life and disability insurance and a 401(k) plan.

Under our 401(k) Plan, all employees and officers are eligible to participate and may elect to defer a portion of their compensation up to the statutorily prescribed limit. Each pay period we make a matching contribution to each employee's deferral, not to exceed 10 percent of compensation. An employee's interests in his or her deferrals and our matching contributions are, in each case, 100% vested when contributed. The 401(k) Plan is intended to qualify under Section 401(a) of the Internal Revenue Code (Code). As such, matching contributions to the 401(k) Plan and earnings on those contributions are not taxable to the employee until distributed from the 401(k) Plan, and all timely made contributions are deductible by us for the year in which they are allocable.

The Company purchases flight time through a private charter aircraft company. Access to private aircraft is made available for business use to our executive officers and employees in accordance with the Company's Aircraft Use Policy. The Company's Aircraft Use Policy does not permit employees, including executive officers, to use these hours for personal use. In limited occasions when a personal guest accompanies an employee on a business-related flight, the Company follows the Internal Revenue Service rules and, where required, will impute income to the employee based on applicable Standard Industry Fare Level rates.

The Company covers the cost of a comprehensive annual physical for its NEOs.

***DIAMONDBACK ENERGY, INC.* •** 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **60**

### **Clawback Policy** 
The Company maintains a "clawback" policy that complies with Listing Standard 5608 adopted by Nasdaq to implement Rule 10D-1 under the Exchange Act. Under the clawback policy, the Company will recoup any excess incentive-based compensation earned by an executive officer (including each of our NEOs), on or after October 2, 2023 and during a three fiscal year lookback period, in the event of a financial restatement if a lesser amount of incentive-based compensation would have been earned had such incentive-based compensation been determined based on the restated results. For purposes of the clawback policy, incentive-based compensation includes any compensation granted, earned or vested based in whole or in part on the Company's attainment of a financial reporting measure.

### **Anti-Hedging and Anti-Pledging Policies** 
We have a policy prohibiting directors, executive officers and certain other designated employees from speculative trading in our securities, including hedging transactions, short selling, and trading in put options, call options, swaps or collars. In addition, we prohibit our directors and executive officers from holding our common stock in a margin account. To our knowledge, all such individuals are in compliance with the policy. Our policy is to also prohibit all other employees from engaging in hedging activities in our stock. We also have a policy prohibiting our directors, executive officers and certain other designated employees from pledging our securities as collateral for a loan.

### **Timing of Equity Awards** 
Grants of equity awards are within the discretion of the compensation committee and are generally made to our named executive officers on March 1 of each year, approximately two weeks after our earnings are announced for the preceding quarter and full fiscal year and following the filing of our Annual Report on Form 10-K for that year. On occasion, the compensation committee may grant equity awards outside of our annual grant cycle for new hires, promotions, recognition, retention or other purposes. We do not currently grant, and have not in recent years granted, stock options, stock appreciation rights (SARs) or other instruments with option-like features to our named executive officers or other employees. The compensation committee did not take material nonpublic information into account when determining the timing and terms of equity awards granted in 2025, and the Company does not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation.

### **Stock Ownership and Retention Guidelines for Non-Employee Directors and Executive Officers** 
The compensation committee has adopted stock ownership and retention guidelines for our non-employee directors and executive officers who are classified as Vice President and above. These guidelines were adopted to encourage our non-employee directors and executives to have a meaningful stake in the Company, which encourages a focus on our long-term success, aligns directors' and executives' interests with the interests of our stockholders and further promotes our commitment to sound corporate governance.

Under the stock ownership and retention guidelines, each of our non-employee directors must own an amount of our common stock equal in value to a multiple of the base annual retainer and our executive officers must own an amount of our and Viper's common stock equal in value to a multiple of his or her annual base salary, as set forth in the table below.

---

| |
|:---|
| **Position** |
| Non-Employee Directors 5x |
| Chief Executive Officer 6x |
| President 4x |
| Executive Vice Presidents 3x |
| Senior Vice Presidents and Vice Presidents 2x |

As of December 31, 2025, the table below provides the minimum value of stock that each of our NEOs (other than Mr. Stice, who will be subject to the stock ownership and retention guidelines in his capacity as a non-employee director (rather than as an executive officer) after the date of the 2026 Annual Meeting) who currently serve as our executive officers must retain under our stock ownership and retention guidelines.

The compensation committee reviews compliance with the stock ownership and retention guidelines on an annual basis. As of December 31, 2025, all NEOs were in compliance with the stock ownership and retention guidelines.

Any participant who acquires shares of our and Viper's common stock via the exercise of options or the vesting of restricted stock or restricted stock units that is granted after the effective date of the guidelines must retain 50% of the net shares acquired until the earlier of (i) the date such participant is determined to be in full compliance with the guidelines and (ii) the date such individual ceases to be a participant subject to the guidelines. Once the ownership requirement is met, the participant must continue to maintain the value amount in accordance with the guidelines.

Any participant subject to the guidelines who is not in compliance with the applicable guideline (after taking into account any compliance transition period) may be required to retain up to 100% of the net shares of our and Viper's common stock acquired via the exercise of options or the vesting of restricted stock unit awards granted under our and Viper's equity incentive programs until the applicable guideline has been met.

Participants generally are given a five-year transition period to come into full compliance with the guidelines. Participants are expected to make steady progress towards meeting the ownership levels specified in the guidelines with any stock awards or stock purchases made on or after the effective date of the guidelines. If an individual becomes subject to a greater ownership amount, due to a promotion, an increase in base salary or an increase in the base retainer, as applicable, the individual is expected to meet the higher ownership amount by the latest to occur of (i) the end of the original period; (ii) three years from the effective date of the promotion, increase in base salary or increase in base retainer, as applicable; and (iii) such date as may be specified by the compensation committee. The compensation committee will evaluate whether exceptions should be made for any participant who, due to his or her unique financial circumstances, would incur a hardship by complying with the guidelines.

"Net shares" means the net number of shares received by the participant upon settlement after taking into account the sale or withholding of shares to pay any applicable taxes and/or option exercise price.

In addition to shares held outright, shares held directly or indirectly in trust, shares held by immediate family members residing in the same household, shares held in qualified plans (e.g., in a 401(k) plan), vested shares held in non-qualified plans, and unvested restricted stock or restricted stock units subject to time-based (but not performance-based) vesting are all counted toward satisfaction of the ownership requirement. Restricted stock units that have vested, but not yet settled, shall be included as long as they do not remain subject to achievement of any performance goals. Stock options (whether vested or unvested) and unvested performance-based awards are not counted as shares owned for the purpose of calculating stock ownership under the guidelines.

### **Annual Incentive Plan** 
In February 2021, the compensation committee of our board of directors adopted the Executive Annual Incentive Compensation Plan (Annual Incentive Plan), replacing our prior 2014 Executive Annual Incentive Compensation Plan. The purpose of the Annual Incentive Plan is to provide an incentive to our executive officers and other selected employees to contribute to the growth, profitability and increased value of the Company. The Annual Incentive Plan is designed to focus on achievement of annual objectives and goals, determined at the beginning of each calendar year. Participants may earn a pre-determined percentage of base salary for the achievement of specified goals (performance targets). The payout opportunity varies for performance above and below the pre-established target performance levels. Performance factors for each award under the Annual Incentive Plan include criteria and objectives determined by the plan administrator used to measure the performance targets during the applicable performance period as a condition to the participant's receipt of payment with respect to an award.

***DIAMONDBACK ENERGY, INC.* •** 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **62**

[Back to Contents](#toc)

All payments in respect of awards granted under the Annual Incentive Plan are made in cash, paid within a reasonable period after the end of the performance period and designed not to be deferred compensation within the meaning of Section 409A of the Internal Revenue Code (Code).

Unless otherwise provided by the compensation committee in connection with a specific termination of employment, if the employment of an NEO or other participant terminates for any reason prior to the payment of any award for any reason other than death or disability, no award will be payable to such participant for that performance period.

In the event of a change in control, as such term is defined in the Annual Incentive Plan, each NEO or other participant will be paid the target award amount (the mid-point of any specified range of potential award payment amounts or performance targets), based on the assumption that the performance target was attained at the target level for the entire performance period, payable within a specified period following the consummation of the change in control transaction.

### **Equity Incentive Plan** 
On April 6, 2021, our board of directors unanimously adopted, subject to stockholder approval, our 2021 Amended and Restated Equity Incentive Plan, amending and restating our 2019 Amended and Restated Equity Incentive Plan. On June 3, 2021, our stockholders approved the 2021 Amended and Restated Equity Incentive Plan. Effective February 11, 2024, the 2021 Amended and Restated Equity Incentive Plan was further revised pursuant to certain clarifying amendments effective February 11, 2024. The 2021 Amended and Restated Equity Incentive Plan, as amended and restated as of the date hereof is referred to as the Equity Incentive Plan.

The Equity Incentive Plan became effective as of April 6, 2021, the date adopted by the compensation committee of our board of directors, and will remain in effect until April 6, 2031, unless otherwise terminated earlier by the board of directors.

The compensation committee may grant awards under the Equity Incentive Plan, which may include restricted awards, performance awards, stock options and stock appreciation rights, to employees, consultants and directors of our Company and its affiliates; however, incentive stock options may be granted only to employees of our Company and its subsidiary corporations. Consultants do not receive awards pursuant to our current equity compensation program.

In the event of certain corporate events or changes in our common stock, the compensation committee will proportionally adjust awards, the number and class of shares available under the Equity Incentive Plan and the maximum number of shares that may be granted under awards to any participant in a calendar year as it determines to be appropriate.

In the event of a change in control transaction or other corporate transaction such as a dissolution or liquidation of our Company, or any corporate separation or division, the Equity Incentive Plan provides that all outstanding awards under the Equity Incentive Plan may be assumed, continued or substituted for by any surviving or acquiring entity (or its parent company), or may be cancelled either with or without consideration for the vested portion of the awards, all as determined by the compensation committee. If an award would be cancelled without payment of consideration to the extent vested, the participant may exercise the award in full or in part for a period of ten days.

Awards granted under the Equity Incentive Plan are subject to the Company's clawback policy, compliant with the Nasdaq listing standards and Rule 10D-1 under the Exchange Act, which allows us to recoup paid incentive compensation from current and former executive officers in certain instances.

### **Effect of Our Compensation Policies and Practices on Risk and Risk Management** 
The compensation committee reviews the risks and rewards associated with our compensation policies and programs. We believe that such policies and programs encourage and reward prudent business judgment and avoid encouraging excessive risk-taking over the long-term. With respect to specific elements of compensation:

&nbsp;&nbsp;&nbsp;&nbsp;• We believe that our programs balance short- and long-term incentives for our
 executive officers providing for an appropriate mix of fixed, discretionary and equity compensation that overall encourages long-term
 performance.

• We believe that annual base salaries for our NEOs do not encourage excessive risk-taking as they
 are fixed amounts that are subject to discretionary increases by our compensation committee, based, among other factors, on annual
 performance evaluations. We also believe that such annual base salaries are set at reasonable levels, as compared to the base salaries
 of similarly situated individuals at our compensation peer group companies. The base salary represents a portion of our NEOs'
 overall compensation potential and is balanced by the other elements of their overall compensation potential, which are tied to both
 performance and long-term service.

***DIAMONDBACK ENERGY, INC.* •** 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **63**

[Back to Contents](#toc)

&nbsp;&nbsp;&nbsp;&nbsp;• Our annual incentive bonuses are designed to award achievement of short-term performance-driven
 results. The payment and amounts of the 2025 annual incentive bonuses were based, in part, upon meeting of certain performance criteria
 and targets established by the compensation committee for 2025, as disclosed in more detail above. We believe the performance criteria
 and applicable targets were set at meaningful levels and do not encourage excessive risk taking.

• Restricted stock units granted to our NEOs are subject to performance-based and time-based provisions.
 We award restricted stock units to promote performance and ensure that our executives have a continuing stake in the long-term success
 of the Company as the value of the award will depend on the stock price at and after the time of vesting. We believe that a mixture
 of performance-based and time-based equity awards represent a balanced approach to long-term equity compensation and do not encourage
 excessive risk taking that may be associated with the compensation approach focused solely on equity awards that vest strictly based
 on achieving certain targets. We also believe that the weight given by our compensation committee to performance-based equity awards,
 as compared to time-based equity awards, provide incentive to our NEOs to take appropriate amount of risk to drive the Company's
 performance and enhance stockholder value.

• Our NEOs are entitled to certain benefits that are payable upon the occurrence of their termination
 without "cause," resignation for "good reason" or certain change in control transactions. See "Potential
 Payments upon Termination, Resignation or Change of Control for Fiscal Year 2025" and "Other Significant Compensation
 and Benefit Plans, Policies and Practices—Senior Management Severance Plan" for more information.

Based on the foregoing, the compensation committee believes that the Company does not utilize compensation policies and programs creating risks that are reasonably likely to have a material adverse impact on the Company.

### **Letter Agreement with Executive Chairman** 
On February 20, 2025, the Company and Mr. Stice entered into a letter agreement specifying the terms on which he will serve as Executive Chairman. The letter agreement provides:

&nbsp;&nbsp;&nbsp;&nbsp;• Mr. Stice will serve as Executive Chairman from the Company's 2025 Annual Meeting
 until the Company's 2026 Annual Meeting, at which point Mr. Stice will transition to non-executive Chairman of the Board.

• Effective as of the Company's 2025 Annual Meeting, Mr. Stice's annual base salary was
 adjusted to $900,000 and his target annual bonus opportunity for 2025 was set at 150%, and, as further detailed below, Mr. Stice's
 2025 payment under the Company's Annual Incentive Plan is based on the blended base salary earned by Mr. Stice before and after
 the effective date of his appointment to Executive Chairman.

• As Executive Chairman, Mr. Stice remains a participant in the Company's Amended and Restated
 Senior Management Severance Plan, except his cash severance benefits not in connection with a change in control were reduced to 24
 months of base salary continuation.

• From Mr. Stice's transition to non-executive Chairman of the Board through December 31, 2026,
 the Company will reimburse the cost of premiums for COBRA group health continuation coverage.

&nbsp;&nbsp;&nbsp;&nbsp;*(2)* *Represents the grant date fair value (calculated as discussed in Note 1 above) of the performance-based restricted stock units for each NEO granted under Diamondback's Equity Incentive Plan and the Viper LTIP for the applicable performance period, subject to the Company's attainment of certain pre-established performance targets and the NEO's continuous employment. The Company utilized a Monte Carlo simulation to value the performance-based restricted stock units granted in 2025 based on the probable performance outcome for the target amount of units on the grant date, consistent with the estimate of aggregate compensation cost to be recognized over the service period. Actual payouts for the performance-based restricted stock units granted in 2025 can range from zero percent up to a maximum equal to 250% of the target number of performance-based restricted stock units granted.* 

*(3)* *The aggregate grant date fair values for 2025, 2024 and 2023 for each NEO are attributable to the time-based restricted stock units granted to such NEO under Diamondback's Equity Incentive Plan on March 1, 2025, May 21, 2025, March 1, 2024, September 10, 2024, and March 1, 2023, respectively, in each case vesting in three substantially equal annual installments beginning on the date of grant.* 

*(4)* *The amounts shown reflect performance-based annual incentive bonuses granted under the Annual Incentive Plan.* 

*(5)* *The following provides a detailed breakdown of the amounts for 2025 under "All Other Compensation" in the Summary Compensation Table:*

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *Reflects performance-based annual incentive cash bonuses granted under the Annual Incentive Plan for 2025. No non-equity incentive plan awards are paid under the Annual Incentive Plan for performance below the pre-determined thresholds.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(2)* *For each NEO, these amounts represent the performance-based restricted stock units granted under the Equity Incentive Plan, which awards are subject to the satisfaction of certain relative TSR performance conditions compared to the Company's TSR performance peer group for the three-year performance period commencing on January 1, 2025 and ending on December 31, 2027, as certified by the compensation committee, and continuous service requirements. The number of restricted stock units that will vest is based on the achievement of a pre-established threshold, target or maximum relative TSR goal, as compared to the Company's peers, as modified by the absolute TSR modifier. The TSR is calculated over the performance period by dividing (1) the sum of (a) the cumulative value of dividends received during the performance period, assuming reinvestment, plus (b) the difference between the average stock price for the month of December 2027 compared to the average stock price for the month of December 2024; by (2) the average stock price for the month of December 2024 ending immediately prior to the beginning of the performance period. No awards vest if the relative TSR for the applicable performance period is below the threshold percentile. The absolute TSR modifier reduces payouts upon negative performance period TSR, pays at target upon achieving a performance period annual TSR of zero to 15%, and increases payouts upon achieving a performance period annual TSR of greater than 15%.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(3)* *Represents the time-based restricted stock units granted to (i) each NEO under the Equity Incentive Plan on March 1, 2025, vesting in three equal annual installments beginning on the date of grant, and (ii) Mr. Van't Hof on May 21, 2025, vesting in three equal annual installments beginning on May 21, 2025. All of these awards are subject to continuous service requirements.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(4)* *The amounts shown reflect the grant date fair value of restricted stock units granted, determined in accordance with FASB ASC Topic 718. See Note 10 to our consolidated financial statements for the fiscal year ended December 31, 2025, included in our Annual Report on Form 10-K, filed with the SEC on February 25, 2026, regarding assumptions underlying valuations of equity awards for 2025.*

The number of restricted stock units that will vest is based on the achievement of a pre-established threshold, target or maximum relative TSR goal, as compared to the Company's peers, as modified by the absolute TSR modifier.

No awards vest if the relative TSR for the applicable performance period is below the threshold percentile. The absolute TSR modifier reduces payouts upon negative performance period TSR, pays at target upon achieving a performance period annual TSR of zero to 15%, and increases payouts upon achieving a performance period annual TSR of greater than 15%.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(3)* *Reflects the target number of performance-based restricted stock units granted based on the performance of the awards from the grant date through December 31, 2025. These performance-based restricted stock units were granted under the LTIP subject to the satisfaction of certain relative TSR performance conditions as compared to our TSR performance peer group for the performance period commencing on January 1, 2025 and ending on December 31, 2027, as certified by the compensation committee, and continuous service requirements. The number of restricted stock units that will vest is based on the achievement of a pre-established threshold, target or maximum relative TSR goal, as compared to the Company's peers, as modified by the absolute TSR modifier. The TSR is calculated over the performance period by dividing (1) the sum of (a) the cumulative value of dividends received during the performance period, assuming reinvestment, plus (b) the difference between the average stock price for the month of December 2027 compared to the average stock price for the month of December 2024; by (2) the average stock price for the month of December 2024. No awards vest if the relative TSR for the applicable performance period is below the threshold percentile. The absolute TSR modifier reduces payouts upon negative performance period TSR, pays at target upon achieving a performance period annual TSR of zero to 15%, and increases payouts upon achieving a performance period annual TSR of greater than 15%.*

&nbsp;&nbsp;&nbsp;&nbsp;*(3)* *The value of restricted stock units was calculated based on the closing price of our common stock of $150.33 per share on December 31, 2025, which is the last trading day of 2025.*

&nbsp;&nbsp;&nbsp;&nbsp;*(9)* *Mr. Stice's participation agreement includes terms that are intended to maintain certain benefits under his prior employment agreement and require each equity award granted to Mr. Stice to become 100% vested upon an eligible termination, and in the case of outstanding performance-based equity awards to vest at the maximum level under the equity award agreement and be settled within ten business days.*

For ease of calculation, the Company assumed the performance conditions were satisfied at target to determine the number of performance-based restricted stock units that such NEO would be entitled to upon a change of control. However, in accordance with the terms of the applicable equity award agreement, actual payouts of the performance-based restricted stock units may be between zero percent up to a maximum equal to 250% of the target number of performance-based restricted stock units granted based on the Company's performance during the relevant performance periods.*

&nbsp;&nbsp;&nbsp;&nbsp;*(12)* *Represents a lump sum cash payment equal to 3x Mr. Stice's base salary plus Mr. Stice's average bonus for the preceding three years ended December 31, 2025 and a target annual cash bonus for the year of termination.*

&nbsp;&nbsp;&nbsp;&nbsp;*(17)* *Under the terms of the applicable award agreement, upon such NEO's death or disability the number of performance-based restricted stock units the officer is entitled to is not determined until the end of the performance period and is settled at the same time it would have had the officer remained employed. For purposes of calculating the number of performance-based restricted stock units that such NEO would be entitled to upon his or her death or disability, the Company assumed that the performance conditions were satisfied at target.*

## **—** **PAY RATIO DISCLOSURE** 
Pursuant to Item 402(u) of Regulation S-K, we are disclosing the pay ratio and supporting information comparing the median of the annual total compensation of our employees (including full-time, part-time, seasonal and temporary employees) other than our principal executive officer ("Chief Executive Officer"), and the annual total compensation of our Chief Executive Officer. The pay ratio is calculated in a manner consistent with Item 402(u) of Regulation S-K. For the year ended December 31, 2025, our last completed fiscal year:

&nbsp;&nbsp;&nbsp;&nbsp;• The median of the annual total compensation of all of our employees, other than
 our Chief Executive Officer, is $168,095.

• The annual total compensation of our Chief Executive Officer serving on December 31, 2025
 is $14,931,423.

• The ratio of the annual total compensation of our Chief Executive Officer to the median of
 the annual total compensation of all other employees is 89 to 1.

To identify the median employee for 2025 (the 2025 Median Employee), we reviewed our employee population as of December 31, 2025. For 2025, we used wages reported in Box 1 of IRS Form W-2 during the 12-month period ending on December 31, 2025, as a consistently applied compensation measure. We did not annualize the wages for new employees or employees on unpaid leave of absence who were employed for less than the full fiscal year, or make cost of living adjustments. Based on this methodology, we identified an employee whose compensation was at the median of the employee data.

Once we identified the 2025 Median Employee, we calculated the annual total compensation using the rules applicable to the Summary Compensation Table. With respect to the annual total compensation of our Chief Executive Officer serving on December 31, 2025, we used the amount reported in the "Total" column for 2025 in the Summary Compensation Table on page 66.

The pay ratio rules provide companies with flexibility to select the methodology and assumptions used to identify the median employee, calculate the median employee's compensation and estimate the pay ratio. As a result, our methodology may differ from those used by other companies, including those within our industry, and may not be comparable to pay ratios reported by other companies.

&nbsp;&nbsp;&nbsp;&nbsp;*(6)* *Represents the weighted peer group TSR, weighted according to the respective companies' stock market capitalization at December 31, 2020. The peer group used for this purpose in 2024 consisted of the following companies: APA Corporation, Coterra Energy, Inc., Devon Energy Corporation, EOG Resources, Inc., Marathon Oil Corporation, Ovintiv Inc. and Permian Resources Corporation. The peer group used for this purpose in 2023 consists of the following companies: APA Corporation, Coterra Energy, Inc., Devon Energy Corporation, EOG Resources, Inc., Hess Corporation, Marathon Oil Corporation, Ovintiv Inc. and Pioneer Natural Resources Company. The peer group used for this purpose in 2022 consisted of the following companies: APA Corporation, Continental Resources, Inc., Coterra Energy, Inc., Devon Energy Corporation, EOG Resources, Inc., Hess Corporation, Marathon Oil Corporation, Ovintiv Inc. and Pioneer Natural Resources Company. In 2025, Marathon Oil Corporation was removed from the 2025 peer group due to its acquisition by ConocoPhillips in November 2024. ConocoPhillips and Occidental Petroleum Corp were added to the 2025 peer group. After the removal of Marathon Oil Corporation, Continental Resources, Inc., Hess Corporation and Pioneer Natural Resources Company, and the addition of ConocoPhillips, Occidental Petroleum Corp and Permian Resources Corporation, the 2022 peer group, 2023 peer group, 2024 peer group and 2025 peer group are made up of the same companies.*

### **Financial Performance Measure** 
As described in greater detail in "Compensation – Compensation Discussion and Analysis," the Company's executive compensation program reflects a variable pay-for-performance philosophy. The metrics that the Company uses for both our long-term and short-term incentive awards are selected based on an objective of incentivizing our NEOs to increase the value of our enterprise for our stockholders. The most important financial performance measures used by the Company to link executive compensation actually paid to the Company's NEOs, for the most recently completed fiscal year, to the Company's performance are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ROACE;

• Free Cash Flow (as defined and reconciled in Schedule A to this proxy statement);

• PDP F&D Cost (as defined in "Compensation Discussion and Analysis – Performance-Based
 Annual Incentive Bonus" above); and

• Relative Total Stockholder Return (as modified by an absolute TSR modifier) (as discussed in "Compensation
 Discussion and Analysis—Long-Term Equity Incentive Compensation—2025 Performance-Based and Time-Based Awards").

### **Analysis of the Information Presented in the Pay Versus Performance Table** 
As described in more detail in the section "Compensation Discussion and Analysis," the Company's executive compensation program reflects a variable pay-for-performance philosophy. While the Company utilizes several performance measures to align executive compensation with Company performance, not all of those Company measures are presented in the Pay versus Performance table consistent with SEC rules. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company's performance measures with compensation that is actually paid (as computed in accordance with SEC rules) for a particular year. In accordance with SEC rules, the Company is providing the following descriptions of the relationships between information presented in the Pay versus Performance table.

## **—** **2025 DIRECTOR COMPENSATION** 
Our non-employee directors receive a combination of cash and equity compensation designed to attract and retain qualified candidates to serve on our board of directors. In setting non-employee director compensation, our board of directors considers the significant amount of time that directors spend in fulfilling their duties to the Company and our stockholders as well as the skill level required by our non-employee directors. The compensation committee is responsible for determining the type and amount of compensation for our non-employee directors. The compensation committee engaged Meridian, as its independent compensation consultant, to assist in the annual review of non-employee director compensation with a view to provide a pay program that compensates non-employee directors near the median of our peers by providing benchmark compensation data and recommendations for non-employee director compensation program design. Employee directors are not separately compensated for their service on the Board.

### **Director Compensation** 
The table below describes the non-employee director compensation program for 2025. The annual retainers for director, Lead Independent Director, committee chair and committee member are payable quarterly in advance to each non-employee director. Under our director compensation program, our non-employee directors may annually elect to defer payment of up to 100% of his or her annual grant of restricted stock units and any related dividend equivalent rights until separation from service as a non-employee director of the Company. A deferral election may be made on a form provided by the compensation committee during the election period established by the compensation committee, which shall end no later than December 31 of the calendar year prior to the award date. Our non-employee directors are also reimbursed for customary expenses incurred while attending meetings of the Board and its committees.

| **Type of Fee** | **Amount<br> ($)** |

| **Annual Other Committee Member Retainer** | $5000 |
| **Annual Restricted Stock Unit Award<sup>(1)</sup>** | $200000 |

---

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *During 2025, we provided our non-employee directors with equity compensation under our equity incentive plan valued at $200,000. The number of restricted stock units awarded to each non-employee director in 2025 equaled $200,000 divided by $141.12 (the average closing price of a share of our common stock for the five trading days immediately preceding the date of grant). The annual grant of restricted stock units is generally made to our non-employee directors at the close of business on the date of each annual meeting of our stockholders. On May 21, 2025, each non-employee director was granted 1,417 restricted stock units which will vest on the earlier of May 21, 2026 and the date of the 2026 Annual Meeting. Non-employee directors that joined the board subsequent to May 21, 2025 received a prorated grant of restricted stock units with the same vesting terms as the annual non-employee director grant.*

See Note 10 to our consolidated financial statements for the fiscal year ended December 31, 2025, included in our Annual Report on Form 10-K, filed with the SEC on February 25, 2026, regarding assumptions underlying valuations of equity awards for 2025. Each non-employee director serving on the Board after the 2025 Annual Meeting on May 21, 2025 was awarded 1,417 restricted stock units on May 21, 2025, which will vest on the earlier of the one-year anniversary of the date of grant and the date of the 2026 Annual Meeting. Except for General Brooks, Mr. Holderness, Mr. Meloy, Mr. Plaumann, Mr. Reeves, Mr. Robertson and Mr. West, each of the other non-employee directors elected to defer the receipt of the vested restricted stock units granted in 2025 until separation from service as a non-employee director of the Company. No additional equity awards were received by our non-employee directors to date in 2026. Dividend equivalent rights are not reflected in the aggregate grant date fair value of the restricted stock unit awards.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(3)* *Mr. Houston did not stand for reelection at the 2025 Annual Meeting.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(4)* *Excludes the compensation awarded to Mr. West for his services as (i) a director and Chairman of the Board of Viper in 2025, which consisted of (a) $75,000 in cash and (b) a grant of 4,173 phantom units on May 20, 2025, with the grant date fair value of $172,595, and a vesting date of May 20, 2026.* 

### **Director Stock Ownership Guidelines** 
The compensation committee has adopted stock ownership and retention guidelines for our non-employee directors. The stock ownership guidelines for our executive officers who are classified as Vice President and above and described in the "Compensation Discussion and Analysis" above. The stock ownership guidelines for our non-employee directors were adopted to encourage our non-employee directors to have a meaningful stake in the Company, which encourages a focus on our long-term success, aligns directors' interests with the interests of our stockholders and further promotes our commitment to sound corporate governance.

Under their stock ownership guidelines, each of our non-employee directors must own an amount of our common stock equal in value to five times of the base annual retainer for non-employee directors. Stock options (whether vested or unvested) and unvested performance-based awards are not counted as shares owned for the purpose of calculating stock ownership under the guidelines.

The determination of a non-employee director's stock ownership requirement will be calculated on an annual measurement date specified by the compensation committee based on the current base retainer of such non-employee director on the measurement date. For purposes of the stock ownership and retention guidelines, the term "base retainer" means the base annual cash retainer that each non-employee director receives for his or her service on our board of directors, which does not include any fees that any non-employee director receives for his or her service as a chair of our board of directors, Chairman Emeritus (or similar role or title), Lead Independent Director, a member of a committee of our board of directors or a chair of a committee of our board of directors.

The compensation committee reviews compliance with the stock ownership and retention guidelines on an annual basis. As of December 31, 2025, all non-employee directors were in compliance with the stock ownership and retention guidelines.

Since our initial public offering in October of 2012, our executive management has been focused not only on achieving peer-leading operational performance and cost structure in the Permian Basin, but also on creating superior stockholder value. The following performance graph includes a comparison of our cumulative total stockholder return from the first trading date following our IPO and for selected years thereafter through December 31, 2025, with the average performance of (i) our 2026 proxy peer group identified in the "Compensation Discussion and Analysis," (ii) the subset of energy companies within our 2026 proxy peer group, (iii) the Standard & Poor's 500 Stock Index, a broad market index, or the S&P 500 Index, and (iv) the SPDR S&P Oil & Gas Exploration and Production ETF, or XOP Index. The graph assumes an investment of $100 on such date, and that all dividends were reinvested.

---

## **—** **REVIEW AND APPROVAL OF RELATED PARTY TRANSACTIONS** 
Our board of directors has adopted a written policy regarding related party transactions. Under the policy, the audit committee reviews and approves all relationships and transactions in which we and our directors, director nominees and executive officers and their immediate family members, as well as holders of more than 5% of any class of our voting securities and their immediate family members, have a direct or indirect material interest. The policy provides that, the following do not create a material direct or indirect interest on behalf of the related party and are therefore not related party transactions:

&nbsp;&nbsp;&nbsp;&nbsp;• a transaction involving compensation of directors;

• a transaction involving compensation of an executive officer or involving an employment agreement, severance arrangement, change
 in control provision or agreement or special supplemental benefit of an executive officer;

• a transaction with a related party involving less than $120,000;

• a transaction in which the interest of the related party arises solely from the ownership of a class of our equity securities
 and all holders of that class receive the same benefit on a pro rata basis;

• a transaction involving indemnification payments and payments under directors and officers indemnification insurance policies
 made pursuant to our certificate of incorporation or bylaws or pursuant to any policy, agreement or instrument of the Company or
 to which the Company is bound; and

• a transaction in which the interest of the related party arises solely from indebtedness of a 5% stockholder or an "immediate
 family member" of a 5% stockholder.

The policy supplements the conflict of interest provisions in our Code of Business Conduct and Ethics.

### **Stephens Stockholders Agreement** 
As discussed elsewhere in this proxy statement, at closing of the Endeavor Merger on September 10, 2024, we entered into the Stephens Stockholders Agreement with the former holders of all the issued and outstanding equity interests in Endeavor Energy Resources, L.P. who received shares of our common stock as consideration for the Endeavor Merger (the "Stephens Stockholders"). The Stephens Stockholders Agreement provides the Stephens Stockholders (through approval of holders of a majority of the total number of shares of common stock held by the Stephens Stockholders) with the right to propose for nomination four directors for election to our board of directors if the Stephens Stockholders beneficially own at least 25% of the outstanding shares of our common stock, two directors if they beneficially own at least 20% but less than 25% of the outstanding shares of our common stock, and one director if they beneficially own at least 10% but less than 20% of the outstanding shares of our common stock, in each case subject to certain qualification requirements for such directors. The Stephens Stockholders are subject to certain transfer, standstill and voting restrictions under the Stephens Stockholders Agreement, and we are restricted from taking certain limited actions without the consent of the holders of a majority of the shares of our common stock held by the Stephens Stockholders.

Under the Stephens Stockholders Agreement, the Stephens Stockholders also have certain registration rights. In particular, the Stephens Stockholders are entitled to make up to three registration demands for an underwritten shelf take-down to sell all or a portion of their registrable securities in any calendar year for so long as they beneficially own registrable securities having a value, in the aggregate, of more than $2,000,000,000 and the gross proceeds from such registration are reasonably expected to be more than $500 million. In addition, the Stephens Stockholders have "piggy-back" registration rights to include their registrable securities in other registration statements filed and other underwritten offerings conducted by us.

***DIAMONDBACK ENERGY, INC.*** • 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **89**

[Back to Contents](#toc)

To satisfy certain of our registration obligations under the Stephens Stockholders Agreement, on September 19, 2024, we filed our registration statement on Form S-3ASR with the SEC, registering under the Securities Act the resale, from time to time, of the registerable securities received by the Stephens Stockholders as merger consideration in the Endeavor Merger, which registration statement became automatically effective upon filing.

Pursuant to the terms of the Stephens Stockholders Agreement, we will generally pay all expenses relating to the registration, offering and listing of these shares, except that any Stephens Stockholders acting as selling stockholders under the registration statement will pay any underwriting fees, discounts and commissions, placement fees of underwriters, broker commissions, transfer taxes and certain attorney's fees. We have also agreed to indemnify the Stephens Stockholders against certain liabilities, including liabilities under the Securities Act, based upon, arising out of, related to or resulting from any untrue or alleged untrue statement of a material fact contained in any registration statement or prospectus filed by us.

The foregoing description of the Stephens Stockholders Agreement does not purport to be complete and is qualified in its entirety by reference to the actual terms of the Stephens Stockholders Agreement, a copy of which is attached as Exhibit 10.1 to our Current Report on Form 8-K filed with the SEC on September 10, 2024.

### **SGF Letter Agreement** 
We entered into a letter agreement with SGF, dated November 28, 2025, which provides SGF with the right, but not the obligation, to sell up to 3,000,000 shares of Diamondback common stock to Diamondback per calendar quarter through December 31, 2026 at the most recent Nasdaq closing price prior to any such transaction, subject to certain terms and conditions set forth in the letter agreement. Pursuant to the letter agreement, on November 28, 2025, Diamondback repurchased 2,000,000 shares of its common stock held by SGF at the most recent Nasdaq closing price of $152.59 per share. Repurchases under the letter agreement are pursuant to Diamondback's existing share repurchase program, and have been approved by the audit committee of Diamondback's Board of Directors. As of March 30, 2026, we have repurchased a total of 5,000,000 shares from SGF for a total cost of $814 million. The letter agreement does not affect SGF's ability to dispose of its Diamondback shares through other means, including registered offerings and open market sales, to the extent permitted under its stockholder agreement with Diamondback.

### **SGF Secondary Offering** 
On March 10, 2026, the Company entered into an underwriting agreement with SGF (the "Selling Stockholder") and Evercore Group L.L.C., Citigroup Global Markets Inc. and J.P. Morgan Securities LLC, as representatives of the several underwriters named therein (the "Underwriters"), pursuant to which, among other things, the Selling Stockholder agreed to sell to the Underwriters, and the Underwriters agreed to purchase from the Selling Stockholder, shares of the Company's common stock (the "Shares") in a registered public offering (the "Secondary Offering"), subject to and upon the terms and conditions set forth therein.

On March 12, 2026, the Company and the Selling Stockholder completed the Secondary Offering of 12,650,000 Shares, which includes 1,650,000 Shares that were purchased by the Underwriters pursuant to a 30-day option that the Selling Stockholder had granted to the Underwriters, which such option was exercised by the Underwriters in full.

Pursuant to the Stephens Stockholders Agreement, we paid all expenses relating to the registration, offering and listing of the shares sold in the Secondary Offering, except that the Selling Stockholder paid the discounts and commissions of the Underwriters, any transfer taxes and certain attorney's fees. Our estimated expenses in connection with the Secondary Offering were approximately $1,020,000.

### **Certain Other Transactions** 
The son of Charles A. Meloy, one of our current directors and director nominees at the 2026 Annual Meeting, owns Oak Prairie Oil & Gas LLC through a trust, of which Mr. Meloy and his spouse are the trustees. Mr. Meloy serves as a director of Oak Prairie Oil & Gas LLC and his son serves as an executive officer of that entity. Oak Prairie Oil & Gas LLC received payments of $2.2 million from Diamondback and/or its subsidiaries during the year ended December 31, 2025, for revenue associated with working interests held in oil and gas properties operated by Diamondback.

| ![](lfang2026_def14ax94x1.jpg) | &nbsp;&nbsp;&nbsp;**PROPOSAL 2** **APPROVE, ON AN ADVISORY BASIS, THE COMPANY'S EXECUTIVE COMPENSATION** |

---

In accordance with Section 14A of the Exchange Act, our board of directors is providing our stockholders with a non-binding advisory vote on the Company's executive compensation as reported in this proxy statement, or "say on pay" vote. The Company's stockholders are being asked to vote on the following resolution:

"RESOLVED, that the compensation paid to the Company's named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby approved."

While the vote on executive compensation is non-binding and solely advisory in nature, our board of directors and the compensation committee will review and consider the "say on pay" voting results when making future decisions regarding our executive compensation program. Our stockholders have a "say on pay" vote each year. The next "say on pay" vote will take place at our 2027 Annual Meeting.

Stockholders are encouraged to carefully review the "Compensation Discussion and Analysis" section of this proxy statement, which discusses in detail the Company's compensation policy and compensation arrangements which the Company believes are appropriate and reasonably consistent with market practice and with the long-term interests of the Company and its stockholders. In furtherance of the Company's goals and objectives, the compensation committee, among other things, ensures that the Company's executive compensation arrangements (i) do not incentivize executives to take unnecessary risks, (ii) do not include excessive change in control provisions, (iii) offer performance-based compensation, consisting of cash compensation with performance goals tied to our Company's performance and performance-based equity awards, based on total stockholder return relative to the peer group and (iv) include long-term vesting provisions in the awards of time-based restricted stock units retain key executive talent and to encourage executives to focus on long-term performance, in each case to motivate our executives to contribute to the growth, profitability and increased value of the Company.

---

## **—** **WHAT AM I VOTING ON?** 
In accordance with Section 14A of the Exchange Act, our board of directors is also providing our stockholders with a non-binding advisory vote on whether future advisory votes on executive compensation of the nature reflected in Proposal 2 should be held every year, every two years or every three years. While this vote is non-binding and solely advisory in nature, our board of directors and the compensation committee will carefully review and consider the voting results when determining the frequency of future advisory votes on executive compensation.

Our board of directors believes that a frequency of "every year" for the advisory vote on executive compensation is an appropriate interval for conducting and responding to a "say on pay" vote. An annual approach provides regular input by stockholders and allows the Company to evaluate the effects of such input on executive compensation on a consistent basis.

The enclosed proxy card gives stockholders four choices for voting on this item. Stockholders can choose whether the advisory vote on executive compensation should be conducted every year, every two years or every three years. Stockholders may also abstain from voting on this item. Stockholders are not voting to approve or disapprove the board of directors' recommendation on this item.

## **—** **WHAT VOTE IS REQUIRED FOR THIS PROPOSAL?** 
With respect to this proposal, stockholders will be able to choose among four options, namely whether future stockholder votes to approve executive compensation should occur every year, every two years or every three years, or whether the stockholder abstains from voting. 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, in favor of one of the voting options contemplated by this proposal is required to approve, on an advisory basis, this proposal. If none of the three voting options is adopted by the required vote of the stockholders, our board of directors will evaluate the votes cast for each of the voting options and will deem the voting option receiving the greatest number of votes to be the voting option approved by the stockholders.

Only votes in favor of one of the voting options contemplated by this proposal will be counted as votes cast and abstentions and broker non-votes will not be counted for voting purposes.

### **Who is soliciting my vote?** 
The board of directors of Diamondback Energy, Inc., which we refer to as "Diamondback," the "Company" and "we" in this proxy statement, is soliciting your vote at the 2026 Annual Meeting of Stockholders.

### **What am I voting on, what are the voting options and how does the board of directors recommend that I vote my shares?**

---

### **Who is entitled to vote?** 
You may vote if you were the record owner of our common stock as of the close of business on March 30, 2026. Each share of common stock is entitled to one vote. As of March 30, 2026, we had 281,311,730 shares of common stock outstanding and entitled to vote. There is no cumulative voting.

### **How many votes must be present to hold the meeting?** 
Your shares are counted as present at the 2026 Annual Meeting if you attend the meeting and vote in person or if you properly grant your proxy by telephone, Internet or mail. In order for us to hold our meeting, holders of a majority of the voting power of our outstanding shares of common stock entitled to vote at the 2026 Annual Meeting must be present in person or by proxy at the meeting. This is referred to as a quorum. Abstentions and broker non-votes will be counted for purposes of establishing a quorum at the meeting.

### **What is a broker non-vote?** 
If a broker does not have discretion to vote shares held in street name on a particular proposal and does not receive instructions from the beneficial owner on how to vote those shares, the broker may not vote on that proposal. This is known as a broker non-vote. No broker may vote your shares without your specific instructions on any of the proposals to be considered at the 2026 Annual Meeting other than on the proposals that are considered to be "routine." Under the rules of the New York Stock Exchange (NYSE), which apply to brokers regardless of whether an issuer is listed on the NYSE or Nasdaq, Proposal 4 relating to the ratification of our independent auditor is considered to be a "routine" matter. Accordingly, brokers will have discretionary authority to vote on Proposal 4 but will not have discretionary authority to vote on Proposal 1, Proposal 2 or Proposal 3 at the 2026 Annual Meeting without your specific instructions.

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *If any incumbent director is not elected because he or she does not receive a majority of the votes cast, he or she is required to immediately tender his or her resignation for consideration by our board of directors. Our board of directors will evaluate whether to accept or reject such resignation, or whether other action should be taken; provided, however, that the board will act on such resignation and publicly disclose its decision to accept or reject such resignation and the rationale behind such decision within 90 days from the date of the certification of the director election results.* 

### **How do I vote?** 
You can vote either in person at the meeting or by proxy without attending the meeting.

To vote by proxy, you may vote by telephone or through the Internet by following the instructions included on the Notice of Internet Availability of Proxy Materials or proxy card, or, if you request to receive a paper copy of the proxy card, by returning a signed, dated and marked proxy card. If you are a registered holder or hold your shares in street name, votes submitted by Internet or telephone must be received by 1:00 a.m., Central Time, on May 20, 2026.

Even if you plan to attend the meeting, we encourage you to vote your shares by proxy. If you plan to vote in person at the 2026 Annual Meeting, and you hold your stock in street name, you must obtain a proxy from your broker and bring that proxy to the meeting. See also "How to attend the Annual Meeting?" below.

### **May I change my vote?** 
Yes, if you are a registered stockholder. You may change or revoke your vote at any time before the polls close at the 2026 Annual Meeting. You may do this by:

&nbsp;&nbsp;&nbsp;&nbsp;• If you voted by telephone or the internet, access the method you used and follow the instructions
 given for revoking a proxy;

• If you mailed a signed proxy card, then mail a new valid proxy card bearing a later date and return
 it to us prior to the 2026 Annual Meeting;

• Submitting another valid proxy bearing a later date and returning it to us prior to the meeting;

• Sending our Corporate Secretary a written document revoking your earlier proxy; or

• Voting again at the 2026 Annual Meeting.

However, if you are a beneficial owner and your shares are held in street name by a broker or other nominee, you must contact your broker or such other nominee to change or revoke your proxy.

***DIAMONDBACK ENERGY, INC.*** • 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **96**

[Back to Contents](#toc)

### **Who counts the votes?** 
We have engaged Computershare Trust Company, N.A., our transfer agent, to count the votes represented by proxies cast by telephone, Internet, mail or ballot. An employee of Computershare Trust Company, N.A. will act as our Inspector of Elections.

### **How are proxies being solicited and who pays the related expenses?** 
Our board of directors has sent you this proxy statement. Our directors, officers and employees may solicit proxies by mail, by telephone or in person. Those persons will receive no additional compensation for any solicitation activities. We will request banking institutions, brokerage firms, custodians, trustees, nominees and fiduciaries to forward solicitation materials to the beneficial owners of common stock held of record by those entities, and we will, upon the request of those record holders, reimburse reasonable forwarding expenses. We have engaged Georgeson LLC ("Georgeson") to assist in the distribution of proxy materials and solicitation of votes. The Company will pay Georgeson a base fee of $23,000, plus customary costs and expenses, for these services and has agreed to indemnify Georgeson against certain liabilities in connection with its engagement. We will pay the costs of preparing, printing, assembling and mailing the proxy material used in the solicitation of proxies.

### **Will my vote be confidential?** 
Yes. As a matter of Company policy, proxies, ballots and voting tabulations that identify individual stockholders are treated as confidential. Only the tabulation agent and the inspector of elections have access to your vote. Directors and employees of the Company may see your vote only if there is a contested proxy solicitation, as required by law or in certain other special circumstances.

### **Where can I find the voting results of the Annual Meeting?** 
We will report the voting results on a Current Report on Form 8-K which will be filed with the SEC no later than four business days after the 2026 Annual Meeting.

### **Will my shares be voted if I don't provide my proxy and don't attend the Annual Meeting?** 
If you do not provide a proxy or vote your shares held in your name, your shares will not be voted.

If you hold your shares in street name, your broker may be able to vote your shares for certain "routine" matters even if you do not provide the broker with voting instructions. As discussed above, Proposal 4 relating to the ratification of Grant Thornton LLP as our independent auditor for 2026 is considered routine. For matters not considered "routine", if you do not give your broker instructions on how to vote your shares, the broker may not vote on that proposal. This is a broker non-vote.

Proposals 1, 2 and 3 are not considered routine. As a result, no broker may vote your shares on these proposals without your specific instructions.

### **Could other matters be decided at the Annual Meeting?** 
We are not aware of any other matters that will be considered at the 2026 Annual Meeting. If any other matters are properly presented to be considered and voted on at the 2026 Annual Meeting, the persons named in your proxies will vote in accordance with their best judgment. Discretionary authority to vote on other matters is included in the proxy.

### **Who can attend the meeting?** 
The 2026 Annual Meeting is only open to holders of our common stock as of the record date, March 30, 2026.

### **What do I need to bring to attend the Annual Meeting?** 
You will need proof of ownership of our common stock to attend the meeting in person. If your shares are in the name of your broker or bank or other nominee, you will need to bring evidence of your stock ownership, such as your most recent brokerage statement. All stockholders will be required to present valid picture identification. IF YOU DO NOT HAVE VALID PICTURE IDENTIFICATION AND PROOF THAT YOU OWN SHARES OF OUR STOCK AS OF THE RECORD DATE, YOU MAY NOT BE ADMITTED INTO THE MEETING.

### **How to attend the Annual Meeting?** 
The 2026 Annual Meeting will be held at our headquarters at 500 West Texas Avenue, Midland, TX 79701. From Midland International Air & Space Port located at 9506 La Force Blvd., keep left on La Force Blvd., turn right on West Highway 80 East toward Odessa, Texas, keep right onto West Highway 80 East, turn left on West Country Road 117, turn left on US-80, continue toward Midland, Texas, then turn left onto North A Street, turn right onto West Texas Avenue and Fasken Tower will be on the left.

### **How can I access the Company's proxy materials and annual report electronically?** 
This proxy statement and the Company's 2025 Annual Report on Form 10-K are available at www.envisionreports.com/FANG.

### **Why did I receive a Notice of Internet Availability of Proxy Materials instead of a paper copy of the proxy materials?** 
We are providing access to our proxy materials, including this proxy statement and our 2025 Annual Report on Form 10-K, over the Internet in accordance with the rules of the Securities and Exchange Commission, or the SEC. As a result, we are mailing to our stockholders a Notice of Internet Availability instead of a paper copy of our proxy materials. Your Notice of Internet Availability contains instructions on how to access our proxy materials over the Internet, as well as instructions on how to request a paper copy of our proxy materials by mail.

Our proxy materials are also available at www.envisionreports.com/FANG.

### **How can I request a full set of proxy materials?** 
You may request, without charge, a full set of our proxy materials, including our 2025 Annual Report on Form 10-K, for one year following the annual meeting of stockholders, by following the instructions contained in the Notice of Internet Availability that you received.

### **What is householding?** 
The SEC permits a single set of Notice of Internet Availability or annual reports and proxy statements to be sent to any household at which two or more stockholders reside if they appear to be members of the same family. Each stockholder continues to receive a separate proxy card, if a proxy card is provided. This procedure, referred to as householding, reduces the volume of duplicate information stockholders receive and reduces our mailing and printing expenses.

If you and other residents at your mailing address own shares of our common stock, you may have only received one Notice of Internet Availability or annual report and proxy statement, unless we have received contrary instructions from you. If you would like to receive your own set of Notice of Internet Availability or the annual report and proxy statement this year or in future years, follow the instructions described below. We will promptly send a separate copy of the Notice of Internet Availability or annual report and proxy statement, as applicable. Similarly, if you share an address with another Diamondback stockholder and together both of you would like to receive in the future only a single Notice of Internet Availability or annual report and proxy statement, follow these instructions:

&nbsp;&nbsp;&nbsp;&nbsp;• If your shares of our common stock are registered in your own name, please contact our transfer agent, Computershare
 Trust Company, N.A., and inform them of your request by calling their toll-free number: (800) 962-4284 or by mail: Computershare
 Trust Company, N.A., 250 Royall Street, Canton, MA 02021.

• If a broker or other nominee holds your shares, please contact your broker or nominee.

### **Availability of Annual Report on Form 10-K**

### **Forward-Looking Statements** 
This proxy statement contains "forward-looking statements" within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act, which involve risks, uncertainties, and assumptions. All statements, other than statements of historical fact, including statements regarding Diamondback's: future performance; business strategy; future operations and plans and objectives of management (including plans for future cash flow from operations and for executing environmental strategies) are forward-looking statements. When used in this proxy statement, the words "aim," "anticipate," "believe," "continue," "could," "estimate," "expect," "forecast," "future," "guidance," "intend," "may," "model," "outlook," "plan," "positioned," "potential," "predict," "project," "seek," "should," "target," "will," "would," and similar expressions (including the negative of such terms) as they relate to Diamondback are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. Although Diamondback believes that the expectations and assumptions reflected in its forward-looking statements are reasonable as and when made, they involve risks and uncertainties that are difficult to predict and, in many cases, beyond Diamondback's control. In addition, some of our sustainability goals, in particular those related to environmental matters, are based on our current expectations that may turn out to be inaccurate. Accordingly, forward-looking statements are not guarantees of future performance and Diamondback's actual outcomes could differ materially from what Diamondback has expressed in its forward-looking statements.

Factors that could cause the outcomes to differ materially include (but are not limited to) the following: geopolitics and market conditions, including, changes in supply and demand levels for oil, natural gas, and natural gas liquids, and the resulting impact on the price for those commodities; changes in U.S. energy, environmental, monetary and trade policies, including with respect to tariffs or other trade barriers and any resulting trade tensions; actions taken by the members of OPEC and its non OPEC allies ("OPEC+") affecting the production and pricing of oil, as well as other domestic and global political, economic, or diplomatic developments, changes in general economic, business or industry conditions, including changes in foreign currency exchange rates, interest rates, inflation rates, and instability in the financial sector; regional supply and demand factors, including delays, curtailment delays or interruptions of production, or governmental orders, rules or regulations that impose production limits; federal and state legislative and regulatory initiatives relating to hydraulic fracturing, including the effect of existing and future laws and governmental regulations; physical and transitional risks relating to climate change; changing political and social perspectives on climate change and other environmental, social and governance factors, and risks from our publicly disclosed targets related to sustainability and emissions reduction initiatives; challenges in developing our existing leasehold acreage and finding, developing or acquiring additional reserves; restrictions on the use of water, including limits on the use of produced water and a moratorium on new produced water disposal well permits recently imposed by the Texas Railroad Commission in an effort to control induced seismicity in the Permian Basin; significant declines in prices for oil, natural gas, or natural gas liquids, which could require recognition of significant impairment charges; conditions in the capital, financial and credit markets, including the availability and pricing of capital for acquisitions, exploration and development operations; challenges with employee retention and an increasingly competitive labor market; changes in availability or cost of rigs, equipment, raw materials, supplies and oilfield services; changes in safety, health, environmental, tax and other regulations or requirements (including those addressing air emissions, water management, or the impact of global climate change); security threats, including cybersecurity threats and disruptions to our business and operations from breaches of our information technology systems, or from breaches of information technology systems of third parties with whom we transact business; lack of, or disruption in, access to adequate and reliable electrical power, internet and telecommunication infrastructure, information and computer systems, transportation, processing, storage and other facilities for our oil, natural gas and natural gas liquids; failures or delays in achieving expected reserve or production levels from existing and future oil and natural gas developments, including due to operating hazards, drilling risks, or the inherent uncertainties in predicting reserve and reservoir performance; inability to keep pace with technological developments in our industry; failure to meet our obligations under our oil purchase contracts; loss of one or more customers or their inability to meet their obligations; geographical concentration of our primary operations; risks from our return of capital commitment, and uncertainties over our future dividends and share repurchases; difficulty in obtaining necessary approvals and permits; severe weather conditions and natural disasters; changes in the financial strength of counterparties to our credit facilities and hedging contracts; our substantial indebtedness and restrictions to

***DIAMONDBACK ENERGY, INC.*** • 2026 PROXY STATEMENT&nbsp;&nbsp;&nbsp;&nbsp; **100**

[Back to Contents](#toc)

our operating and financial flexibility; changes in our credit rating; failure to identify, complete and successfully integrate acquisitions, including the recently completed Double Eagle Acquisition and Viper's Sitio Acquisition; the Endeavor equityholders' ability to significantly influence our business and potential conflicts of interest; and other; and the risks and other factors disclosed in Diamondback's filings with the Securities and Exchange Commission, including on our latest annual report on Form 10-K, subsequent reports on Forms 10-Q and 8-K, which can be obtained free of charge on the Securities and Exchange Commission's web site at http://www.sec.gov. Given these risks and uncertainties, investors are cautioned not to place undue reliance on such forward-looking statements.

In light of these factors, the events anticipated by Diamondback's forward-looking statements may not occur at the time anticipated or at all. Moreover, Diamondback operates in a very competitive and rapidly changing environment and new risks emerge from time to time. Diamondback cannot predict all risks, nor can it assess the impact of all factors on its business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those anticipated by any forward-looking statements it may make. Accordingly, you should not place undue reliance on any forward-looking statements made in this proxy statement. All forward-looking statements speak only as of the date of this proxy statement or, if earlier, as of the date they were made. Diamondback does not intend to, and disclaims any obligation to, update or revise any forward-looking statements unless required by applicable law.

No reports, documents or websites that are cited or referred to in this proxy statement shall be deemed to form part of, or to be incorporated by reference into, this proxy statement.

## — **OPERATING CASH FLOW BEFORE WORKING CAPITAL CHANGES; FREE CASH FLOW AND ADJUSTED FREE CASH FLOW** 
Operating cash flow before working capital changes, which is a non-GAAP financial measure, represents net cash provided by operating activities as determined under GAAP without regard to changes in working capital. The Company believes operating cash flow before working capital changes is a useful measure of an oil and natural gas company's ability to generate cash used to fund exploration, development and acquisition activities and service debt or pay dividends. The Company also uses this measure because changes in working capital relate to the timing of cash receipts and disbursements that the Company may not control and may not relate to the period in which the operating activities occurred. This allows the Company to compare its operating performance with that of other companies without regard to financing methods and capital structure.

The Company defines Free Cash Flow, which is a non-GAAP financial measure, as cash flow from operating activities before changes in working capital in excess of cash capital expenditures. The Company defines Adjusted Free Cash Flow, which is a non-GAAP financial measure, as Free Cash Flow before the tax impact from divestitures, merger and transaction expenses, costs of early termination of derivatives and settlements of any treasury locks. The Company believes that Free Cash Flow and Adjusted Free Cash Flow are useful to investors as they provide a measure to compare both cash flow from operating activities and additions to oil and natural gas properties across periods on a consistent basis, adjusted, as applicable, for non- recurring impacts from divestitures, merger and transaction expenses, the early termination of derivative contracts and settlements of treasury locks. These measures should not be considered as an alternative to, or more meaningful than, net cash provided by operating activities as an indicator of liquidity. The Company's computation of Free Cash Flow may not be comparable to other similarly titled measures of other companies.

These measures should not be considered as an alternative to, or more meaningful than, net cash provided by operating activities as an indicator of operating performance. The Company's computation of operating cash flow before working capital changes and Free Cash Flow may not be comparable to other similarly titled measures of other companies.

The following table presents a non-GAAP reconciliation of net cash provided by operating activities, a GAAP financial measure, to Free Cash Flow, a non-GAAP financial measure.

## **—** **ADJUSTED EBITDA AND RETURN ON AVERAGE CAPITAL EMPLOYED** 
Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. The Company defines Adjusted EBITDA as net income (loss) attributable to Diamondback Energy, Inc., plus net income (loss) attributable to non-controlling interest ("net income (loss)") before non-cash (gain) loss on derivative instruments, net, interest expense, net, depreciation, depletion, amortization and accretion, depreciation and interest expense related to equity method investments, (gain) loss on extinguishment of debt, impairment of oil and natural gas properties, non-cash equity-based compensation expense, capitalized equity-based compensation expense, other non-cash transactions and provision for (benefit from) income taxes. Adjusted EBITDA is not a measure of net income as determined by United States generally accepted accounting principles ("GAAP"). Management believes Adjusted EBITDA is useful because the measure allows it to evaluate the Company's operating performance and compare the results of its operations from period to period without regard to its financing methods or capital structure. The Company excludes the items listed above from net income (loss) to determine Adjusted EBITDA because these amounts can vary substantially from company to company within its industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Further, the Company excludes the effects of significant transactions that may affect earnings but are unpredictable in nature, timing and amount, although they may recur in different reporting periods. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP or as an indicator of the Company's operating performance. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company's financial performance, such as a company's cost of capital and tax structure, as well as the historic costs of depreciable assets. The Company's computation of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies or to such measure in our credit facility or any of our other contracts.

Return on Average Capital Employed, or ROACE, is a supplemental non-GAAP financial measure that is used by management to measure profitability after factoring in the amount of capital used in the Company's operations. The Company defines ROACE as consolidated Adjusted EBITDA less depreciation, depletion, amortization and accretion ("Adjusted EBIT"), divided by the sum of the average total assets less average current liabilities ("capital employed") for the current year and prior year. ROACE should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP or as an indicator of the Company's operating performance or liquidity. For 2024, management made further adjustments to (i) Adjusted EBIT to remove the net effect of the EBIT attributable to the Endeavor Merger for the period from September 10, 2024 through December 31, 2024, and (ii) average capital employed to remove the net average capital employed for the Endeavor Merger, ("Adjusted ROACE").

The following table presents a non-GAAP reconciliation of Net income (loss) attributable to Diamondback Energy, Inc., a GAAP measure, to Adjusted EBITDA, a non-GAAP financial measure, and the further reconciliation to ROACE, an additional non-GAAP financial measure (in millions).
