The Board of Directors of the Company (the “Board of Directors” or “Board”) is providing the information in this proxy statement to you in connection with the solicitation of proxies for the matters to be voted on at the Annual Meeting of Stockholders (the “Annual Meeting”) that will be held May 21, 2026, at 8:00 a.m. Central Time, at 811 Louisiana Street, Suite 2100, Houston, TX 77002. By submitting your proxy card, you authorize the persons named on the proxy card to represent you and vote your shares at the Annual Meeting. Those persons will also be authorized to vote your shares to adjourn the Annual Meeting from time to time and to vote your shares at any adjournments or postponements of the Annual Meeting.

We encourage you to vote your shares prior to the Annual Meeting. If you attend the Annual Meeting, you may vote in person. Only stockholders of the Company (or their authorized representatives) and the Company’s invited guests may attend the Annual Meeting. All attendees should be prepared to present government-issued photo identification (such as a driver’s license or passport) for admittance. If you are not present at the Annual Meeting, your shares may be voted only by a person to whom you have given a proper proxy. You may revoke your proxy in writing at any time before it is exercised at the Annual Meeting by delivering to the Secretary of the Company a written notice of the revocation, by submitting your vote electronically through the internet or by phone after the grant of your proxy, or by signing and delivering to the Secretary of the Company a proxy card with a later date. Your attendance at the Annual Meeting will not revoke your proxy unless you give written notice of revocation to the Secretary of the Company before your proxy is exercised or unless you vote your shares in person at the Annual Meeting.

Electronic Availability of Proxy Statement and Annual Report

As permitted under the rules of the Securities and Exchange Commission (the “SEC”), the Company is making this proxy statement and its Annual Report on Form 10-K available to its stockholders electronically via the internet. On or about March 26, 2026, the Company is sending a Notice Regarding the Availability of Proxy Materials (the “Notice”) to its stockholders of record as of the close of business on March 24, 2026, which Notice will include (i) instructions on how to access the Company’s proxy materials electronically, (ii) the date, time and location of the Annual Meeting, (iii) a description of the matters intended to be acted upon at the Annual Meeting, (iv) a list of the materials being made available electronically, (v) instructions on how a stockholder can request to receive paper or e-mail copies of the Company’s proxy materials, (vi) any control/identification numbers that a stockholder needs to access his or her proxy card and instructions on how to access the proxy card, and (vii) information about attending the Annual Meeting and voting in person.

Stockholders of Record and Beneficial Owners

Most of the Company’s stockholders hold their shares through a broker, bank or other nominee rather than directly in their own name. As summarized below, there are some distinctions between shares held of record and those owned beneficially.

Stockholders of Record. If your shares are registered directly in your name with the Company’s transfer agent, you are considered the stockholder of record with respect to those shares, and the Notice is being sent directly to you by our agent. As a stockholder of record, you have the right to vote by proxy or to vote in person at the Annual Meeting. If you received a paper copy of the proxy materials by mail instead of the Notice, the proxy materials include a proxy card for the Annual Meeting.

Beneficial Owners. If your shares are held in a brokerage account or by a bank or other nominee, you are considered the beneficial owner of shares held in “street name,” and the Notice will be forwarded to you by your bank, broker or nominee. The bank, broker or nominee is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker how to vote. Beneficial owners that receive the Notice by mail from the stockholder of record should follow the instructions included in the Notice to view the proxy statement and transmit voting instructions. If you received a paper copy of the proxy materials by mail instead of the Notice, the proxy materials include a voting instruction card for the Annual Meeting. To vote electronically over the internet or by telephone, you should follow the instructions provided to you by your bank, broker or other nominee.

If you are a beneficial owner and want to vote your shares at the Annual Meeting, you will need to ask your bank, broker or other nominee to furnish you with a legal proxy. You will not be able to vote your shares at the Annual Meeting without a legal proxy provided by your bank, broker or other nominee.

If you are a beneficial owner, you must follow the instructions provided to you by your bank, broker or other nominee to revoke prior voting instructions. Your attendance at the Annual Meeting will not revoke your vote unless you obtain a legal proxy from your bank, broker or other nominee and you vote your shares in person at the Annual Meeting.

QUORUM AND VOTING

Voting Stock. The Company’s common stock, par value $0.001 per share (“common stock”), is the only class of securities that entitles holders to vote generally at meetings of the Company’s stockholders. Each share of common stock outstanding on the record date is entitled to one vote. Following the Annual Meeting, voting results will be tabulated and certified by the inspector of elections appointed by the Board and timely announced by the Company.

Record Date. The record date for stockholders entitled to notice of and to vote at the Annual Meeting is the close of business on March 24, 2026. As of the record date, there were a total of 214,801,969 shares of common stock outstanding and entitled to be voted at the Annual Meeting.

Quorum and Adjournments. The presence, in person or by proxy, of the holders of a majority of the outstanding shares entitled to vote generally in the election of directors at the Annual Meeting is necessary to constitute a quorum at the Annual Meeting.

If a quorum is not present, a majority of the stockholders who are present in person or by proxy at the Annual Meeting have the power to adjourn the Annual Meeting from time to time, without notice other than as required by applicable law, until a quorum is present. At any adjourned Annual Meeting at which a quorum is present, any business may be transacted that might have been transacted at the Annual Meeting as originally notified.

Vote Required. The votes required to pass each proposal is as follows:

If your shares of common stock are held in the name of a bank, broker or other holder of record, you will receive instructions from that holder of record that you must follow in order for your shares to be voted at the Annual Meeting. Brokers who hold shares in street name for customers are required to vote shares in accordance with instructions received from the beneficial owners.

Default Voting. A proxy card that is properly completed and submitted will be voted at the Annual Meeting in accordance with the instructions on the proxy card. If you properly complete and submit a proxy card, but do not indicate any contrary voting instructions, your shares will be voted consistent with the Board of Directors’ recommendation as follows:

If any other business properly comes before the stockholders for a vote at the meeting, your shares will be voted in accordance with the discretion of the holders of your proxy. The Board of Directors knows of no matters, other than those previously stated, to be presented for consideration at the Annual Meeting.

To provide these services, we operate in two primary segments: (i) Gathering and Processing, and (ii) Logistics and Transportation (also referred to as our Downstream Business).

Our Gathering and Processing segment includes assets used in the gathering and/or purchase and sale of natural gas produced from oil and gas wells, removing impurities and processing this raw natural gas into merchantable natural gas by extracting NGLs; and assets used for the gathering and terminaling and/or purchase and sale of crude oil. The Gathering and Processing segment’s assets are located in the Permian Basin of West Texas and Southeast New Mexico (including the Midland, Central and Delaware Basins); the Eagle Ford Shale in South Texas; the Barnett Shale in North Texas; the Anadarko, Ardmore, and Arkoma Basins in Oklahoma (including the SCOOP and STACK) and South Central Kansas; the Williston Basin in North Dakota (including the Bakken and Three Forks plays); and the onshore and near offshore regions of the Louisiana Gulf Coast.

SUSTAINABILITY AT TARGA

As part of our Board of Directors’ continued commitment to sustainability, our Sustainability Committee oversees sustainability matters, including governance in relation to such matters. This includes overseeing management’s process for establishing and implementing a strategy to integrate sustainability into various business activities of the Company, with the goal of creating long-term stakeholder benefits. The full Board of Directors also reviews the Company’s progress at each quarterly board meeting. Our CEO and Executive Management team oversee the development, implementation, and reporting of our sustainability practices, and facilitate our enterprise risk management process with participation and oversight from the Board of Directors.

Our Performance

We continue to engage with our stakeholders regarding our sustainability efforts and are proud of the progress we have made. Our sustainability initiatives and priorities are driven by what is best for long-term sustainable value creation and stakeholder feedback helps inform our efforts.

Prioritizing the health and safety of our people is embedded in everything we do. Our multiyear investment in and implementation of standardized processes and digital systems, training programs, and proactive work practices has seen record levels of success. Since 2021, we have achieved a 22% reduction in our Total Recordable Incident Rate. In 2024, we completed approximately 74,000 total safety and environmental training hours. We also introduced a new contractor-specific Learning Management System, which offers position-specific safety training. We are focused on continuing to champion a culture of safety and on advancing programs that protect our employees, contractors and the communities we serve.

We continue to make progress on key strategic initiatives including avoided emissions through continued investment in electric compression, the implementation of new advanced monitoring technologies, and ongoing optimization across our systems, as well as an on-going commitment to and leadership in methane management and limiting methane loss in our systems. Key achievements in 2024 included:

Despite growing our asset footprint significantly, which has resulted in record volumes, our GHG intensity has decreased over the last five years. We remain committed to our continued efforts to optimize operations, utilize data and advance monitoring and abatement technology to manage emissions.

As we look forward, we will continue to strive to improve our performance, conduct our business safely and with integrity, and create lasting benefits for all of our stakeholders.

We invite you to review our 2024 Sustainability Report, which is available on the Company’s website at https://www.targaresources.com/sustainability. However, please note that the content of that report, and other materials on our website, are not incorporated into this proxy statement by reference. Additionally, we may provide information in this proxy statement that is not necessarily “material” under the federal securities laws for SEC reporting purposes, but that is informed by various sustainability standards and frameworks (including standards for the measurement of underlying data), and the interests of various stakeholders, which may be impacted by matters outside of our control. This proxy statement also contains forward-looking statements, which may be impacted by many risks, including those identified in our most recently filed Annual Report on Form 10-K. Accordingly, the actual conduct of our activities, including the setting and pursuit of any goals, strategies, priorities, and initiatives discussed and forecasted in this proxy statement, may differ materially in the future. We may set, measure and report on various emissions metrics, including emissions-related goals, which are generally aspirational in nature and often reliant on estimated information, complex assumptions and hypothetical scenarios, all of which are inherently imprecise. The setting, achievement or progress against such metrics or goals may change in the future as methodologies for such activities continue to evolve. Moreover, under current or future approaches to setting, measuring or reporting on various emissions metrics, we may not be able to meet our goals and targets for various technical, logistical, financial or other reasons.

PROPOSAL ONE

ELECTION OF DIRECTORS

The Board of Directors has nominated the following individuals for election as Class I Directors of the Company to serve for a three-year term to expire at the 2029 annual meeting of stockholders:

Ms. Fulton and Messrs. Chung, Crisp and Teague are currently serving as directors of the Company. Their biographical information is contained in the “Directors and Executive Officers” section below.

The Board currently consists of eleven directors. As part of our ongoing Board succession, Director Rene R. Joyce announced his retirement from the Board effective as of the date of the Annual Meeting. Mr. Joyce’s decision to retire was not the result of any disagreement with the Company or any of its affiliates on any matter relating to the Company’s operations, policies or practices. Our bylaws provide that the number of directors will be determined by the Board of Directors, and the number of directors is currently set at eleven. We will reduce the number of directors to ten following the Annual Meeting.

The Board of Directors has no reason to believe that any of its nominees will be unable or unwilling to serve if elected. If a nominee becomes unable or unwilling to accept nomination or election, either the number of the Company’s directors will be reduced or the persons acting via proxy will vote for the election of a substitute nominee that the Board of Directors recommends.

Our bylaws provide that in an uncontested election, each director will be elected by the affirmative vote of a majority of the votes cast by the holders of shares entitled to vote with respect to that director’s election (meaning that the number of votes cast “for” a director’s election must exceed the number of votes cast “against” that director’s election). Under our bylaws, each incumbent director nominated for election must submit an irrevocable resignation, contingent on (i) not receiving a majority of the votes cast in an uncontested election, and (ii) acceptance of that proffered resignation by the Board of Directors in accordance with the following policies and procedures. In the event an incumbent director fails to receive a majority of the votes cast in an uncontested election, the Nominating and Governance Committee, or such other committee designated by the Board, will make a recommendation to the Board of Directors as to whether to accept or reject the resignation of such incumbent director, or whether other action should be taken. The Board of Directors will act on the proffered resignation, taking into account such committee’s recommendation, and publicly disclose its decision regarding the resignation and, if such resignation is rejected, the rationale behind the decision within ninety days following certification of the election results. Such committee, in making its recommendation, and the Board of Directors, in making its decision, each may consider any factors and other information that they consider appropriate and relevant. The director whose resignation is being considered will not participate in the deliberations of such committee or the Board of Directors with respect to whether to accept such director’s resignation. If the director’s resignation is not accepted by the Board of Directors, such director will continue to serve until his or her successor is duly elected, or until his or her earlier resignation or removal.

Vote Required

The affirmative vote of a majority of the votes cast by the holders of shares entitled to vote with respect to each director’s election is required to elect that director (meaning that the number of votes cast “for” a director’s election must exceed the number of votes cast “against” that director’s election). If you own shares through a bank, broker or other holder of record, you must instruct your bank, broker or other holder of record how to vote in order for them to vote your shares so that your vote can be counted on this proposal. Please see “Quorum and Voting—Vote Required” for further information regarding the impact of abstentions and broker non-votes.

Summary of Director Qualifications and Experience

This table provides a summary view of the qualifications and attributes of each director and director nominee.

Board Composition and Governance Highlights(1)

BOARD OF DIRECTORS AND COMMITTEES

Board of Directors

Our Board of Directors currently consists of eleven members. The Board of Directors reviewed the independence of our directors using the independence standards of the New York Stock Exchange (“NYSE”) and various other factors discussed under “Director Independence” and, based on this review, determined that Mses. Bowman, Cooksen, Fulton and Lawhorn and Messrs. Chung, Crisp, Davis, Joyce, Perkins and Teague are independent within the meaning of the NYSE listing standards currently in effect. Mr. Joyce is retiring from the Board, effective as of the date of the Annual Meeting. The Board held ten meetings during 2025. In addition, the independent members of the Board of Directors meet in executive session without the presence of the CEO or other members of management at least once annually. During 2025, each of the directors that served on the Board of Directors attended 99% of the aggregate of the total number of meetings of the Board and the total number of meetings of all committees of the Board on which that director served.

Our directors are divided into three classes serving staggered three-year terms. Class I, Class II and Class III directors will serve until our annual meetings of stockholders in 2026, 2027 and 2028, respectively. The Class I directors are Messrs. Chung, Crisp and Teague and Ms. Fulton, the Class II directors are Mr. Perkins and Mses. Bowman and Cooksen and the Class III directors are Messrs. Davis, Joyce (who is retiring from the Board) and Meloy and Ms. Lawhorn. At each annual meeting of stockholders, directors will be elected to succeed the class of directors whose terms have expired. This classification of our Board of Directors could have the effect of increasing the length of time necessary to change the composition of a majority of the Board of Directors. In general, at least two annual meetings of stockholders will be necessary for stockholders to effect a change in a majority of the members of the Board of Directors.

Our Board regularly reviews our corporate governance structure, including our classified Board. Our industry is a cyclical one that we believe rewards long-term outlook by management and directors. To that end, we believe our current structure of a classified Board with staggered terms allows us to focus on managing our business for greater returns to shareholders over the long-term rather than short-term trends that can be encouraged by annual elections. Despite having three-year terms, the Board has remained focused on refreshment and bringing new perspectives to the Board. As of the date of the Annual Meeting, since 2024 we will have had (i) three directors retire or choose not to stand for reelection; and (ii) we will have added two accomplished, independent directors.

Committees of the Board of Directors

Our Board of Directors has a standing Audit Committee, Compensation Committee, Nominating and Governance Committee, Risk Management Committee and Sustainability Committee, and may have such other committees as the Board of Directors shall determine from time to time. Each of the standing committees of the Board of Directors has the composition and responsibilities described below.

Audit Committee

The members of our Audit Committee are Ms. Lawhorn and Messrs. Davis and Teague. Ms. Lawhorn is the Chairman of this committee. Our Board of Directors has affirmatively determined that each of the members of the Audit Committee is independent as described in the rules of the NYSE and the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Our Board of Directors has also determined that, based upon relevant experience, Ms. Lawhorn is an “audit committee financial expert” as defined in Item 407 of Regulation S-K.

The Audit Committee:

We have adopted an Audit Committee charter defining the committee’s primary duties in a manner consistent with the rules of the SEC and NYSE that is posted on the Company’s website at www.targaresources.com/investors/corporate-governance. The Audit Committee held four meetings during 2025.

Compensation Committee

The members of our Compensation Committee are Mr. Teague and Mses. Cooksen and Bowman. Ms. Bowman is the Chairman of this committee. This committee establishes salaries, incentives and other forms of compensation for officers, directors and other employees. This includes establishing the portion of our compensation program that aligns executive compensation with strategic sustainability goals and targets that are core to our business. Our goals and targets are directly tied to variables that are essential to Targa’s strategy, such as safety and our methane management practices. Our Compensation Committee also administers our incentive compensation and benefit plans, and oversees our clawback policy. We have adopted a Compensation Committee charter defining the committee’s primary duties in a manner consistent with the rules of the SEC and NYSE that is posted on the Company’s website at www.targaresources.com/investors/corporate-governance. The Compensation Committee held five meetings during 2025. Our Board of Directors has determined that each of the members of the Compensation Committee is (i) independent under the NYSE’s rules governing Compensation Committee membership; and (ii) a “non-employee director” under Rule 16b-3 of the Exchange Act.

The Compensation Committee has the authority to retain, compensate, direct, oversee and terminate outside counsel, compensation consultants and other advisors hired to assist the Compensation Committee. In May 2025, the Compensation Committee retained Meridian Compensation Partners, LLC (the “Compensation Consultant” or “Meridian”) as its independent compensation consultant for matters related to executive and non-management director compensation. The Compensation Consultant reports to the Compensation Committee and does not provide any additional services to us.

In May 2025, the Compensation Committee considered the independence of Meridian in light of SEC rules and the NYSE listing standards. The Compensation Committee requested and received a letter from Meridian addressing the consulting firm’s independence, including the following factors:

The Compensation Committee discussed these considerations and concluded that the work of Meridian did not raise any conflict of interest.

Nominating and Governance Committee

The members of our Nominating and Governance Committee are Mr. Crisp and Mses. Cooksen and Fulton. Ms. Fulton is the Chairman of this committee. This committee identifies, evaluates and recommends qualified nominees to serve on our Board of Directors, develops and oversees our internal corporate governance processes and maintains a management succession plan. We have adopted a Nominating and Governance Committee charter defining the committee’s primary duties in a manner consistent with the rules of the SEC and NYSE that is posted on the Company’s website at www.targaresources.com/investors/corporate-governance. The Nominating and Governance Committee held two meetings during 2025. Our Board of Directors has determined that each of the members of the Nominating and Governance Committee is independent under the NYSE’s rules governing board membership.

In evaluating director candidates, the Nominating and Governance Committee assesses whether a candidate possesses the integrity, judgment, knowledge, experience, skills and expertise that are likely to enhance the Board’s ability to manage and direct the affairs and business of the Company, including, when applicable, to enhance the ability of committees of the Board to fulfill their duties.

Risk Management Committee

The members of our Risk Management Committee are Messrs. Joyce (who is retiring from the Board as of the Annual Meeting), Perkins, Davis and Ms. Lawhorn. Mr. Perkins is the Chairman of this committee. This committee oversees our commodity price and commodity basis risk management and hedging activity.

The primary purpose of our commodity risk management activities is to hedge our exposure to price risk and to mitigate the impact of fluctuations in commodity prices on cash flow.

We have adopted a Risk Management Committee charter defining the committee’s primary duties that is posted on the Company’s website at www.targaresources.com/investors/corporate-governance. The Risk Management Committee held four meetings during 2025.

Sustainability Committee

The members of our Sustainability Committee are Ms. Bowman and Messrs. Chung, Crisp and Joyce. Mr. Chung is the Chairman of this committee. This committee oversees the Company’s sustainability matters, including governance in relation to such matters.

The primary purpose of our Sustainability Committee is to assist the Board in overseeing our compliance with all laws, regulations and Company policies and procedures related to sustainability matters, including our stakeholder engagement program as it relates to sustainability and the establishment and retention of a varied workforce. Our Sustainability Committee also oversees management’s process for establishing and implementing a strategy to integrate sustainability into various business activities of the Company to create long-term stakeholder benefits, including disclosures related thereto.

We have adopted a Sustainability Committee charter defining the committee’s primary duties that is posted on the Company’s website at www.targaresources.com/investors/corporate-governance. The Sustainability Committee held four meetings during 2025.

CORPORATE GOVERNANCE

Corporate Governance Guidelines

The Board of Directors believes that sound governance practices and policies provide an important framework to assist it in fulfilling its duty to stockholders. The Company’s “Corporate Governance Guidelines” cover the following principal subjects:

The Corporate Governance Guidelines are posted on the Company’s website at www.targaresources.com/investors/corporate-governance. The Corporate Governance Guidelines will be reviewed periodically, and any proposed additions to or amendments of the Corporate Governance Guidelines will be presented to the Board of Directors for its approval.

The NYSE has adopted rules that require listed companies to adopt governance guidelines covering certain matters. The Company believes that the Corporate Governance Guidelines comply with the NYSE rules.

Board Leadership

Mr. Chung has served as Chairman of the Board of the Company’s Board of Directors since January 1, 2021 and served as Executive Vice President and Senior Legal Advisor of the Company between March 1, 2020 and December 31, 2020. Mr. Meloy has served as Chief Executive Officer and as a director of the Company since March 1, 2020. Although the positions of Chief Executive Officer and Chairman of the Board of Directors are held currently by different individuals, our bylaws allow the same individual to hold the position of Chief Executive Officer and Chairman of the Board of Directors.

To further ensure a strong and independent board, the Board appointed Ms. Fulton as Lead Independent Director, and all directors of the Company, other than Mr. Meloy, are independent. Given the strong leadership of the Company’s CEO, the effective counterbalancing role of the Chairman, the strong Lead Independent Director, and a Board comprised of strong and independent directors, the Board believes that, at the present time, the current structure of the Board best serves the interests of the Company and its stockholders.

In his capacity as chair of the meetings of non-management directors, Mr. Chung provides, in conjunction with the CEO, leadership and guidance to the Board of Directors. He also (i) establishes the agenda for each meeting of the non-management directors and (ii) provides the Board’s guidance and feedback to the CEO and the Company’s management team. All directors are encouraged to suggest the inclusion of agenda items or revisions to meeting materials, and any director is free to raise at any Board meeting items that are not on the agenda for that meeting.

In her capacity as the Lead Independent Director, Ms. Fulton (i) presides at executive sessions of the independent directors and has the authority to call additional executive sessions or meetings of the independent directors and (ii) presides at Board meetings of the non-management directors in the Chairman’s absence. The Lead Independent Director is available for consultation and direct communication with major stockholders, if requested.

The non-management members of the Board of Directors regularly meet in executive session without the presence of the CEO or other members of management. In addition, the independent members of the Board of Directors meet in executive session without the presence of the CEO or other members of management at least once annually. Mr. Chung is chair of meetings of the non-management directors and Ms. Fulton chairs the meetings of the independent directors.

Board Composition

It is the responsibility of the Nominating and Governance Committee to identify, evaluate and recommend to the Board of Directors nominees for election at the annual meeting of stockholders, as well as to fill vacancies or additions on the Board of Directors that may occur between annual meetings. The Committee considers a varied pool of candidates for new member election to the Board of Directors, considering each candidate’s individual business and professional experience, demonstrated leadership ability, diversity of experience, and acumen (financial, industry, technology, investor, and other specialized skills). In assessing the composition of the Board of Directors, the Board and the Nominating and Governance Committee strive to achieve an overall balance and variety of backgrounds and experience with a complementary mix of skills, viewpoints, and professional experience in areas relevant to the Company’s business and strategy.

When recommending director candidates, the Nominating and Governance Committee also considers and reviews each candidate’s business judgment, service on boards of directors of other companies and other time commitments, personal and professional integrity, including commitment to the Company’s core values, openness and ability to work as part of a team and willingness to commit the required time to serve as a board member and familiarity with the Company and its industry. The Board has a policy limiting the number of public company boards a director may serve on. The policy, which can be found in our Corporate Governance Guidelines, states that Directors should not serve on more than three other boards of public companies in addition to the Company’s Board. The Chief Executive Officer should not serve on the boards of more than two other public companies in addition to the Company’s Board. Any exception requires a determination by the Board or the Nominating and Governance Committee that such service does not impair the director’s ability to effectively serve as a member of the Board. The Nominating and Governance Committee has determined that, in its view, no director on the Board currently has time commitments that would prevent such director from properly discharging his or her duties as a director.

Our Nominating and Governance Committee remains focused on broadening the mix of skills, expertise, and viewpoints considered in deliberations on potential appointments and succession planning. This approach is embedded in our Board’s refreshment plans and our annual evaluation of Board effectiveness and composition.

When identifying potential director candidates, the Nominating and Governance Committee relies on a variety of sources available for the identification and recommendation of candidates, including current directors and officers and stockholders. In addition, the Nominating and Governance Committee from time to time may engage a third party search firm to identify or evaluate, or assist in identifying or evaluating potential candidates, for which the third party search firm will be paid a fee.

Communications with the Board of Directors

Stockholders or other interested parties can contact any director (including the Chairman of the Board, Mr. Chung, or the Lead Independent Director, Ms. Fulton), any committee of the Board of Directors, or our non-management directors as a group, by writing to them at Targa Resources Corp., 811 Louisiana Street, Suite 2100, Houston, Texas 77002, Attention: Secretary. Comments or complaints relating to the Company’s accounting, internal accounting controls or auditing matters will also be referred to members of the Audit Committee. The Secretary will review these communications and will forward any communications that they determine bears substantively on the business, management, or governance of the Company.

Director Independence

The Company’s standards for determining director independence require the assessment of directors’ independence each year. A director cannot be considered independent unless the Board of Directors affirmatively determines that he or she does not have any relationship with management or the Company that may interfere with the exercise of his or her independent judgment, including any of the relationships that would disqualify the director from being independent under the rules of the NYSE.

The Board of Directors has assessed the independence of each director and each nominee for director under the Company’s guidelines and the independence standards of the NYSE. The Board of Directors affirmatively determined that Mses. Bowman, Cooksen, Fulton and Lawhorn and Messrs. Chung, Crisp, Davis, Joyce, Perkins, and Teague are independent. Mr. Joyce is retiring from the Board, effective as of the date of the Annual Meeting.

Insider Trading Policy

The Company has adopted an insider trading policy (the “Insider Trading Policy”) governing transactions in its securities and the securities of its subsidiaries by its directors, officers and employees (“Insiders”), in an effort to promote compliance with insider trading laws, rules and regulations, and the exchange listing standards applicable to the Company.

All Insiders are prohibited from (i) transacting or tipping others who may trade in any of the Company’s securities while aware of material nonpublic information about the Company, (ii) transacting or tipping others who may trade in securities of another company while aware of material nonpublic information regarding such company that he or she obtained in the course of his/her employment with the Company and (iii) transacting in the Company’s securities during defined window periods that precede and follow the end of each fiscal quarter or year. Certain Insiders are also prohibited from (a) purchasing the Company’s common stock on margin, (b) selling the Company’s common stock short, (c) purchasing or selling options of any kind, or other derivative securities relating to the Company’s common stock, (d) entering into pledges of the Company’s securities as collateral and (e) engaging in certain hedging transactions. While the Company is not subject to the Insider Trading Policy, the Company’s policy is to comply with applicable law when transacting in its securities.

A copy of the Insider Trading Policy is included as Exhibit 19.1 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

Financial Literacy of Audit Committee and Designation of Financial Experts

The Board of Directors has determined that each of the Audit Committee members is financially literate and that the Chairman of the Audit Committee, Ms. Lawhorn, is an audit committee financial expert as defined by the SEC.

Oversight of Risk Management

Except for the responsibilities of the Audit Committee, Risk Management Committee and Sustainability Committee discussed below, the Board of Directors as a whole (including the committees of the Board of Directors) oversees the assessment of major risks that the Company faces in the short-, intermediate- and long-term timeframe, and the management of such risks. For example, at least annually, the Board of Directors, including the committees of the Board of Directors:

The Company’s Audit Committee oversees the assessment and management of financial reporting and internal control risks, as well as other risks such as credit risk exposure to counterparties. The Audit Committee also oversees the Company’s data privacy, cybersecurity and information technology risks, including key initiatives

and action plans in those areas. Management and the Company’s external auditors provide regular reports to the Audit Committee on these matters. The Company’s Sustainability Committee assists the Board of Directors in overseeing our sustainability-related risks and environmental and safety performance. The Company’s Risk Management Committee monitors our commodity price and commodity basis risk management and hedging activity. Given the strong leadership of the Company’s CEO, the effective counterbalancing role of the Chairman and a Board comprised of strong and independent directors, the Board believes that, at the present time, the current structure of the Board best serves the interests of the Company and its stockholders in overseeing and managing the Company’s major risks.

Attendance at Annual Meetings

While there is no formal attendance policy, the Board of Directors encourages all directors to attend the annual meetings of stockholders, if practicable. We anticipate that the majority of our directors will attend the Annual Meeting. All eleven directors serving at the time attended the annual meeting of stockholders in 2025.  

Shareholder Engagement

At Targa, we value robust engagement with our shareholders. We communicate with our shareholders through various platforms, including SEC filings, quarterly earnings calls and press releases, investor conferences, our sustainability report, written correspondence and regular shareholder meetings and calls. We also have dedicated governance, strategy and sustainability-oriented engagement each fall. These engagements provide an important platform for Targa’s management team and Board of Directors to communicate business, governance, sustainability, and other updates to shareholders and to receive feedback on key topics. We have an established track record of engaging with our shareholders and updating our disclosures or practices by incorporating shareholder feedback into our ongoing practices. Below are just some examples of actions we have taken across these topics in the past four years in light of shareholder feedback:

In the fall of 2025, we reached out to our top 30 shareholders, which represented approximately 58% of shares outstanding.

Our engagements with shareholders cover a variety of topics, including business strategy and performance, corporate governance, executive compensation, and sustainability-related matters. These discussions typically include some combination of our President, Chief Financial Officer, Investor Relations Department, VP – Sustainability, and General Counsel and Secretary. Overall, shareholders were positive in their feedback, specifically regarding:

We view the disclosures within our report as responsive to our shareholders’ feedback at this time and remain committed to further regular engagement with shareholders to understand their views across a variety of topics. For additional information, we invite you to visit our most recent sustainability report which is available on the Company’s website at https://www.targaresources.com/sustainability. However, please note that the content of that report, and other materials on our website, are not incorporated into this proxy statement by reference. Additionally, we may provide information in this proxy statement that is not necessarily “material” under the federal securities laws for SEC reporting purposes, but that is informed by various sustainability standards and frameworks (including standards for the measurement of underlying data), and the interests of various stakeholders, which may be impacted by matters outside of our control. This proxy statement also contains forward-looking statements, which may be impacted by many risks, including those identified on our most recently filed Annual Report on Form 10-K.

We encourage you to read this CD&A in combination with the compensation tables that follow for context regarding the Compensation Committee’s 2025 decisions on compensation for our Named Executive Officers (NEOs), as listed below.

Our Compensation Committee will continue to consider improvements to our programs in light of shareholder feedback, changing industry conditions, and evolving best practices.

2025 EXECUTIVE COMPENSATION PROGRAM SNAPSHOT

Compensation Philosophy and Guiding Principles

The philosophy underlying our executive compensation program is to employ the best leaders in our industry to ensure we execute on our business goals, promote both short-and long-term profitable growth of the Company and create long-term shareholder value. As such, our program is grounded in the following principles:

Good Governance Foundation

The following practices and policies in our executive compensation program promote sound compensation governance and align the interests of our shareholders and executives:

Elements of Pay

The following principle pay elements support the grounding principles of our program:

Pay Mix

Emphasis on at-risk variable compensation. We remain committed to our emphasis on at-risk, incentive-based pay – with payouts tied to our performance through several strategic and financial objectives including relative TSR, and realizable pay heavily dependent upon our ability to grow shareholder value. The charts below show the mix of total direct compensation of our CEO and our other NEOs for 2025. These charts illustrate that a majority of NEO total direct compensation is at-risk (91% for our CEO and an average of 84% for our other NEOs).

Target Total Direct Compensation Mix(1)

CEO Pay at a Glance

Realizable pay aligned with performance. Our emphasis on at-risk, variable and performance-based pay elements, particularly equity incentives, helps to ensure actual compensation realized by our NEOs aligns with returns to our shareholders. As shown in the charts below, CEO realizable pay over the past three- and five-year periods has aligned closely with our TSR performance.

Granted compensation is the sum of base salary, target bonus opportunity, and reported grant-date value of equity awards in each year. Realizable compensation includes base salary, actual annual cash incentive earned,

and the value of any equity incentive grants valued based upon the period-ending stock price and target PSU payouts based upon relative performance. For our annual comparison of realizable pay to TSR performance, the applicable stock price is calculated as of December 31st of each year. For our three-year cumulative summary, the applicable stock price is the closing price on December 31, 2025. Any performance award granted and settled within the five-year or three-year period covered has been adjusted for actual payout percent. Awards that are still outstanding have been adjusted to reflect absolute and relative performance through the end of 2025. Note that the “realizable pay” calculations within this CD&A are not intended to be calculated in accordance with the SEC’s rules regarding “compensation actually paid” within the section below titled “Pay versus Performance.”

OUR DECISION-MAKING PROCESS

The Role of Market References in Setting Compensation

For purposes of setting compensation levels for 2025, the Compensation Committee worked with its independent compensation consultant to review market data from our peers and from broader market survey sources to provide a reference and framework for decisions about the base salary and target annual and long-term incentives for each NEO. The Compensation Committee considers this information carefully and generally desires to be competitive approximately within the median range factoring in performance and experience for total compensation opportunities, although we do not formally benchmark any item of compensation to a specific level compared to our peers. Consequently, in setting pay levels of our NEOs, the Committee considers a variety of additional factors, including individual performance, competencies, skills, potential, prior experience, scope of responsibility and accountability within the organization.

Compensation Peer Group

For purposes of setting compensation levels for 2025, the Compensation Committee worked closely with its independent compensation consultant and senior management to develop a representative peer group. The 2025 compensation peer group consisted of a mix of 15 midstream and exploration and production companies of similar financial size that we believe are a reasonable reflection of the market in which we compete for executive talent. Our 2025 peer group included several changes to reflect the impact of M&A activity:

The Compensation Committee reviews the composition of our peer group every year with its independent consultant in order to ensure that the companies in the group continue to reflect an appropriate reference point for NEO compensation at Targa.

The Role of the Compensation Committee

The Compensation Committee oversees the executive compensation program for our NEOs. The Compensation Committee is comprised of independent, non-employee members of the Board. The Compensation Committee works very closely with its independent consultant and senior management to examine the effectiveness of the Company’s executive compensation program throughout the year. Details of the Compensation Committee’s authority and responsibilities are specified in the Compensation Committee’s charter, which may be accessed at our website, www.targaresources.com, by clicking “Investors,” and then “Corporate Governance.”

The Role of Senior Management

Members of our senior management team attend regular meetings where executive compensation, Company and individual performance, and competitive compensation levels and practices are discussed and evaluated. Our CEO reviews his recommendations pertaining to NEO pay with the Compensation Committee, providing transparency and oversight. The CEO does not participate in the deliberations of the Compensation Committee regarding his own compensation. The members of the Compensation Committee make all final determinations regarding CEO and NEO compensation.

The Role of the Independent Consultant

The Compensation Committee has the authority to engage and retain an independent compensation consultant to provide independent counsel and advice. At least annually, the Compensation Committee formally conducts an evaluation as to the effectiveness of the independent compensation consultant and periodically requests proposals from other potential consulting firms to ensure the independent compensation consultant is meeting the Compensation Committee’s needs. During 2025, the Compensation Committee retained the services of Meridian Compensation Partners (Meridian) as its independent compensation consultant for matters related to executive and non-management director compensation.

The Compensation Committee assessed the independence of Meridian as required under NYSE listing rules. The Compensation Committee has also considered and assessed all relevant factors, including but not limited to those set forth in Rule 10C-1(b)(4)(i) through (vi) under the Exchange Act, that could give rise to a potential conflict of interest with respect to Meridian. Based on this review, we are not aware of any conflicts of interest raised by the work performed by Meridian that would prevent the consultant from serving as an independent advisor to the Compensation Committee.

2025 EXECUTIVE COMPENSATION PROGRAM IN DETAIL

Base Salary

The Compensation Committee approved adjustments to base salaries for the NEOs for 2025 based on its assessment of the competitive market, expected salary increases across the midstream sector, and projected salary adjustments for other employees within Targa.

The 2025 base salary rates for our NEOs were as follows:

Annual Incentives

For 2025, our NEOs were eligible to receive annual incentive awards under the 2025 Annual Incentive Compensation Program (the “2025 Bonus Plan”) which was approved by the Compensation Committee in March 2025 and consists of cash awards under the Second Amended and Restated 2010 Stock Incentive Plan (the “Stock Incentive Plan”).

Target Bonus Amounts. Target bonus opportunities are expressed as a percentage of base salary and were established based on the NEO’s level of responsibility and ability to impact overall results. The Compensation Committee also considered market data in setting target bonus amounts. The 2025 target bonus opportunities were as follows:

2025 Bonus Plan Funding Levels. Annual bonus awards are based upon a rigorous evaluation of results across a variety of financial, operational and strategic categories. Performance is measured against a combination of:

∎ Pre-established financial and operational goals; and

∎ Key strategic business priorities.

Plan funding incorporates formulaic quantitative evaluation and qualitative evaluation based on a holistic evaluation by the Compensation Committee. We believe this balance of formulaic and qualitative evaluation is critical, reflecting the complexity of our business and our desire to ensure that decision-making over the short-term remains focused on producing sustainable growth over the long term.

Evaluation of 2025 Performance. Our evaluation of performance in the annual incentive program includes consideration of performance on multiple factors within three general categories and with a safety category overlay:

The table below provides the more specific items within the first three general categories that our Compensation Committee used when determining the 2025 bonuses. Financial performance metrics have a maximum payout factor of 2.5 and operational performance metrics and sustainability metrics have a maximum payout factor of 2.0. The total plan is capped at a factor of 2.0 regardless of scoring for the individual components.

* Note: Adjusted EBITDA is a non-GAAP measure. Please see the section of this proxy statement entitled “Non-GAAP Financial Measures” for a discussion of adjusted EBITDA and a reconciliation of such measure to its most directly comparable GAAP financial measure. 3-Year ROIC is calculated as (2025 adjusted EBITDA less 2022 adjusted EBITDA) divided by (50% of 2022 growth capital plus FY 2023 growth capital plus 2024 growth capital plus 50% of 2025 growth capital less adjustments for major growth capital projects not yet contributing to earnings).

2025 Bonus Plan Payouts. The Compensation Committee separately reviewed our safety performance for 2025, which included improved safety statistics with severity rate and total recordable injuries. The Compensation Committee did not apply any adjustment to the pool to reflect safety performance.

Based on the Company’s strong financial and operational performance during 2025, our calculated payout under the plan was 1.9x target.

Individual Performance Multiplier. The Compensation Committee also evaluated the executive group and each officer’s individual performance for the year and determined that there were no special circumstances that would result in adjustment to any NEO’s performance factor for 2025. As a result, the Compensation Committee determined a performance multiplier of 1.0x should be applied to each NEO for 2025 based on the officer’s individual performance and performance as part of the executive team.

Settlement of 2025 Bonus Awards. The following table reflects the actual awards received by our NEOs under the 2025 Bonus Plan:

2026 Annual Incentive Cash Compensation Program. For 2026, our NEOs are eligible to receive annual cash awards under the 2026 Annual Incentive Cash Compensation Program (the “2026 Bonus Plan”), which was approved by the Compensation Committee in March 2026. The payments under the 2026 Bonus Plan consist of cash awards that may be made under the Stock Incentive Plan. Our evaluation of performance in the 2026 Bonus Plan will include consideration of performance on multiple factors within the following three categories: Financial Performance, Commercial and Operational Performance and Sustainability. The metrics evaluated within each category will be reflective of the year’s strategic priorities.

Long-Term Equity Incentives

Equity compensation directly aligns the interests of the NEOs with those of our stockholders. In 2025, the Company granted equity compensation under our Stock Incentive Plan as follows:

Long-term equity incentive awards are expressed as a total dollar value based on a percentage of the NEO’s base salary and were established based on the NEO’s level of responsibility and ability to impact overall results. The Compensation Committee also considers market data in setting target long-term equity incentive awards. For awards granted in 2025, the specified percentage of each NEO’s base salary used for purposes of determining the amount of long-term equity incentive awards granted and the corresponding dollar values are set forth in the following table:

2025 PSU Plan Design

PSUs vest depending on the satisfaction of certain service-related conditions and the Company’s TSR relative to the TSR of the members of the LTIP Peer Group measured over a single three-year performance period. For the 2025 PSUs, the LTIP Peer Group was composed of the companies that make up the Alerian US Midstream Index (AMUS), using the following payout schedule:

Target payout is set at the 55th percentile to ensure that a target payout requires performance above the median of our performance peers. Payout for performance between threshold and target or between target and maximum are calculated using straight-line interpolation.

The performance period for the 2025 PSUs began on January 1, 2025 and ends on December 31, 2027, and TSR for the period is measured using the following formula:

2023 – 2025 PSU Plan Payout

The PSUs granted to our NEOs in 2023 used a similar structure as the 2025 PSUs for the period from January 1, 2023 through December 31, 2025. The LTIP Peer Group for the 2023 PSUs was the companies in the AMUS index as of the beginning of the performance period.

On January 15, 2026, our Compensation Committee determined that the overall vesting percentage that was earned for the 2023 PSUs was 250% of target based upon performance in the top decile of the AMUS index companies:

Because vesting did not occur until our Compensation Committee determined the achievement of applicable performance goals at the beginning of 2026, these awards were still considered “outstanding” as of December 31, 2025 for purposes of the compensation tables that follow this CD&A.

OTHER EXECUTIVE COMPENSATION PRACTICES AND POLICIES

Stock Ownership Guidelines

Our Compensation Committee has adopted Stock Ownership Guidelines for our independent directors and executive officers. We believe that our Stock Ownership Guidelines align the interests of our executive officers and independent directors with the interests of our stockholders. The guidelines below were established with advice from the Compensation Consultant and are believed to follow market standards.

The CEO, executive officers and directors have five years from the date first subject to the guidelines to meet the applicable ownership levels. Stock owned directly by an officer or independent director as well as unvested restricted stock units will count for purposes of determining stock ownership levels. All NEOs are compliant with our Stock Ownership Guidelines.

Anti-Hedging and Anti-Pledging Policy

As described above under “Corporate Governance—Insider Trading Policy,” our Insider Trading Policy prohibits Insiders from purchasing our securities on margin and pledging our securities as collateral. In addition, such policy prohibits directors and officers from engaging in transactions designed to hedge or offset a decrease in the value of our securities but permits exchange fund transactions and the purchase of related financial instruments that in substance represent dispositions.

Incentive Compensation Recovery Policy

In September 2023, our Board adopted an executive incentive compensation recovery policy effective as of October 2023, to comply with Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 following implementation of final rules by the NYSE. Our policy provides that incentive-based compensation (cash or equity) paid to our current or former Section 16 officers must be recovered (unless impracticable) in the event of a restatement of the Company’s financial results that would result in such officers receiving erroneously awarded compensation. In connection with such event, the Compensation Committee will have the right to require the reimbursement or forfeiture of any incentive-based compensation, including payments under the annual incentive plan and performance-based PSUs, paid to the officer to the extent permitted by applicable law. The clawback policy applies to all incentive-based compensation deemed “received” under the clawback rules on or after October 2, 2023.

Furthermore, restricted stock, restricted stock unit and performance share unit agreements covering awards made to our named executive officers and other applicable employees include language providing that any compensation, payments or benefits provided under such an award (including profits realized from the sale of earned shares) are subject to clawback to the extent required by applicable law.

Compensation Risk Assessment

The Compensation Committee reviews the relationship between our risk management policies and compensation policies and practices each year and, for 2025, has concluded that we do not have any compensation policies or practices that expose us to excessive or unnecessary risks that are reasonably likely to have a material adverse effect on us. Because our Compensation Committee retains the sole discretion for determining the actual amount paid to executives pursuant to our annual incentive bonus program, our Compensation Committee is able to assess the actual behavior of our executives as it relates to risk-taking in awarding bonus amounts. In addition, the performance objectives applicable to our annual bonus program consist of diverse company-wide and business unit goals, including commercial, operational and financial goals to support our business plan and priorities, which we believe lessens the potential incentive to focus on meeting certain short-term goals at the expense of longer-term risk. Further, our use of long-term equity incentive compensation for 2025 with three-year vesting periods in combination with meaningful ownership requirements serves our executive compensation program’s goal of aligning the interests of executives and shareholders, thereby reducing the incentives to unnecessary risk-taking.

Retirement, Health and Welfare, and Other Benefits

Employees are eligible to participate in a section 401(k) tax-qualified, defined contribution plan (the “401(k) Plan”), which helps employees save for retirement through a tax-advantaged combination of employee and company contributions and directly manage their retirement plan assets through a variety of investment options. Under the plan, participants may elect to defer up to 30% of their eligible compensation on a pre-tax basis (or on a post-tax basis via a Roth contribution), subject to certain limitations under the Internal Revenue Code of 1986, as amended (the “Code”). In addition, we make the following contributions to the 401(k) Plan for the benefit of our employees, including our NEOs: (i) 3% of the employee’s eligible compensation, and (ii) an amount equal to the employee’s contributions to the 401(k) Plan up to 5% of the employee’s eligible compensation. In addition, we may also make discretionary contributions to the 401(k) Plan for the benefit of employees depending on our performance. Company contributions to the 401(k) Plan may be subject to certain limitations under the Code for certain employees. We do not maintain a defined benefit pension plan or a nonqualified deferred compensation plan for our NEOs or other employees.

All full-time employees, including our NEOs, are eligible to participate in our health and welfare benefit programs, including medical, life insurance, dental coverage and disability insurance. It is the Compensation Committee’s policy not to pay for perquisites for any of our NEOs, other than minimal parking subsidies.

Change in Control and Severance Benefits

Our ability to build the exceptional leadership team we have today was due in large part to our having the full complement of compensation tools available to us and the flexibility to use them. This includes the ability to leverage change in control and severance benefits.

The Compensation Committee believes that together, our change in control and severance benefits, which are guided by our governance practices and policies, are well-aligned with those of our peers. More importantly, they foster stability and focus within the senior leadership team by helping to ensure that personal concerns regarding job security do not hinder mergers, reorganizations or other transactions that may be in the best interest of shareholders.

Please see “Executive Compensation—Potential Payments Upon Termination or Change in Control” below for further information.

Accounting Considerations

We account for the equity compensation expense for our employees, including our named executive officers, under the rules of Financial Accounting Standards Board (“FASB”), Accounting Standards Codification (“ASC”) Topic 718. This regulation requires us to record an expense for each award of long-term equity incentive compensation over the vesting period of the award based on the fair value at the grant date. Accounting rules also require us to record cash compensation as an expense at the time the obligation is accrued.

Tax Considerations

We consider the impact of various tax rules in implementing our compensation program. Section 162(m) of the Code (“Section 162(m)”) generally limits the deductibility by a corporation of compensation in excess of $1,000,000 paid to certain executive officers. Our Compensation Committee believes that its primary

responsibility is to provide a compensation program that is consistent with its compensation philosophy and supports the achievement of its compensation objectives. Therefore, the Compensation Committee has retained the authority to grant appropriate compensation items or awards to our service providers notwithstanding an adverse tax or accounting treatment for that compensation.
