subsidiaries, including Magellan Midstream Partners, L.P., a wholly owned subsidiary of ONEOK, Inc. ("Magellan"), EnLink Midstream, LLC, and

after the EnLink acquisition completed on January 31, 2025, Elk Merger Sub II, L.L.C., a wholly owned subsidiary of ONEOK, Inc. ("EnLink"), and

future operations, economic performance or related assumptions, are forward-looking statements made under the provision of the “Safe Harbor”

section of the Private Securities Litigation Reform Act of 1995. Forward-looking statements may include words such as “anticipates,” “believes,”

“continues,” “could,” “estimates,” “expect,” “forecasts,” “goal,” “guidance,” “intends,” “may,” “might,” “outlook,” “plans,” “potential,” “projects,”

“scheduled,” “should,” “target,” “will,” “would” and other words and terms of similar meaning. Although we believe that our expectations regarding

future events are based on reasonable assumptions, we can give no assurance that such expectations or assumptions will be achieved. Important

factors that could cause actual results to differ materially from those in the forward-looking statements are described under Part I, Item 1A, Risk

Factors, and Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations and “Forward-Looking

Statements,” in our 2024 Annual Report on Form 10-K and other filings with the Securities and Exchange Commission. Certain statements contained

in this proxy statement, particularly pertaining to our environmental, social and governance (“ESG”) performance, goals, targets, and initiatives, are

subject to additional risks and uncertainties, including regarding gathering and verification of information and related methodological considerations;

our ability to implement various initiatives under expected timeframes, cost, and complexity; our dependency on third-parties to provide certain

information and to comply with applicable laws and policies; and other unforeseen events or conditions. These factors, as well as others, may cause

results to differ materially and adversely from those expressed in any of our forward-looking statements. All forward-looking statements included in

this document are based on information available to us on the date hereof. We do not undertake and specifically disclaim any obligation to update

any forward-looking statements, except as required under applicable law. Additionally, certain information provided herein or elsewhere, such as our

stakeholders. Such information is not necessarily “material” under the federal securities laws for Securities and Exchange Commission reporting

purposes, even if significant or if we use language of “materiality.” In particular, materiality is used in varying senses in the ESG context. Much of this

information is subject to, assumptions, estimates or third-party information that is still evolving and subject to change. For example, our disclosures

based on certain standards may change due to revisions in framework requirements, availability of information, changes in our business or

applicable government policies, or other factors, some of which may be beyond our control. We cannot guarantee that our disclosures, under such

standards or otherwise, will necessarily align with the preferences or interpretations of any particular stakeholder.

BUSINESS HIGHLIGHTS

Our Business

We are incorporated under the laws of the state of Oklahoma, and our common stock is listed on the New York Stock Exchange (“NYSE”) under the

trading symbol “OKE.” We deliver energy products and services vital to an advancing world. We are a leading midstream service provider of

gathering, processing, fractionation, transportation, storage and marine export services. As one of the largest diversified energy infrastructure

companies in North America, we are delivering energy that makes a difference in the lives of people in the U.S. and around the world. Through our

now approximately 60,000- mile pipeline network, we transport the natural gas, natural gas liquids (“NGLs”), refined products and crude oil that help

meet domestic and international energy demand, contribute to energy security and provide safe, reliable and responsible energy solutions needed

today and into the future .

Our Growth Journey

Since September 2023, ONEOK has embarked on a transformative journey of growth, closing a

series of acquisitions that have strengthened our position as an energy industry leader by

adding new growth platforms in crude oil and refined products to our stable and reliable natural

gas and NGLs businesses.

The successful acquisition of Magellan in September 2023 diversified the company’s assets,

adding a refined products and crude oil business to ONEOK’s portfolio. Building on this

momentum, ONEOK further bolstered its portfolio in 2024-2025 with acquisitions of a Gulf Coast

NGL pipeline system from Easton Energy and the acquisitions of Medallion and EnLink.

These acquisitions expanded and extended our integrated position in some of the most prolific

basins in the U.S. – including the Permian Basin – with connectivity to critical energy demand

hubs across the country like the Texas and Louisiana Gulf Coast.

Our growth strategy

is intentional and

disciplined.

Summary Proxy Information

Business Update and Market Conditions

We operate primarily fee-based businesses in each of our four reportable segments (Natural Gas Gathering and Processing; Refined Products and

Crude; Natural Gas Liquids; and Natural Gas Pipelines), and our consolidated earnings were approximately 90% fee-based in 2024.

Over the past year, we experienced significant growth across our value chain due to our recent acquisitions. Earnings increased in 2024, compared

with 2023, due primarily to a full year of earnings from the new Refined Products and Crude segment, higher NGL and natural gas processing

volumes in the Rocky Mountain region and the impact of the interstate pipeline system divestiture in the Natural Gas Pipelines segment. Our

extensive and integrated assets are located in, and connected with, some of the most productive shale basins, as well as refineries and demand

centers, in the United States.

Financial Performance

Our 2024 consolidated operating income was approximately $5.0 b illion, compared with approximately $4.1 billion in 2023. 2024 net income was

approximately $3.1 billion compared with 2023 net income of approximately $2.7 billion .

Summary Proxy Information

●	RISK OVERSIGHT BY THE BOARD, including regular engagement with and updates by our CEO, executive management and others and a comprehensive annual Enterprise Risk Management (“ERM”) process that encompasses the identification and assessment of a broad range of risks and the development of plans to mitigate these risks. Such risks generally relate to strategic, operational, financial, regulatory compliance, climate-related considerations, ESG, cybersecurity and human capital management aspects of our business. • With the increasing focus on climate-related disclosures, and as part of its oversight responsibilities, our Board sought and received additional updates on this topic from executive management. • As a result, at all 2024 regular in-person Board meetings, and at some telephonic meetings, the Board received updates on climate-related disclosures. Such practice is expected to continue in 2025. • Cybersecurity risks are communicated and discussed with our Board at least annually in conjunction with our overall ERM program. Our Internal Audit group provides periodic updates to our Audit Committee on testing completed to meet the Transportation Security Administration ("TSA") requirements. As part of its oversight responsibilities, our Board also receives frequent updates from executive management on our company’s physical and cybersecurity efforts.
●	ESG OVERSIGHT BY THE BOARD, including regular engagement with and updates by our CEO, executive management and others. • Regular updates to the Board on sustainability, including safety and health, ESG performance, community leadership and investment, and oversight of public policy engagement. • Our Board conducts a biannual examination of the company’s ESG practices, performance, risks and opportunities. Such examinations have been incorporated into the company's Audit Committee Charter, as amended and restated February 21, 2024, and are scheduled to take place at the Board’s February and August meetings. • In 2024, these examinations covered topics such as environmental, safety and health performance, mechanical integrity, process safety, integration and continuous improvement plans, greenhouse gas (“GHG”) emission trends, GHG emissions reduction performance, new regulatory requirements, ESG-related shareholder engagements, ESG performance, risks and opportunities.
●	HUMAN CAPITAL MANAGEMENT OVERSIGHT BY THE BOARD, including regular engagement with and updates by our CEO, executive management and others. • Our Board conducts a biannual examination of the company’s human capital management practices, performance, risks and opportunities. Such examinations have been incorporated into the company's Executive Compensation Committee (the “Committee”) Charter, as amended and restated February 21, 2024, and are scheduled to take place at the Board’s February and August meetings. • In 2024, these examinations covered topics such as workforce inclusion, people, culture, talent recruitment, integration, engagement, development, succession, employee benefits, business resource groups, community, awards and recognition.
●	OVERSIGHT OF OUR LOBBYING AND POLITICAL ACTIVITIES is conducted by our Board and the Corporate Governance Committee. We believe this oversight process facilitates accountability and transparency concerning our lobbying and political activities. • As a company, we generally do not make corporate contributions to (i) political candidates, parties, committees or campaigns, or (ii) 501(c)(4) organizations formed for political purposes. We have made such contributions in the past, but they were very infrequent and for immaterial amounts. We have no intention of making such contributions in the future, and any decision to do so would be subject to review by the Corporate Governance Committee.

Summary Proxy Information

EXECUTIVE COMPENSATION HIGHLIGHTS

Program Design

A principal feature of our compensation program is the determination of executive pay by the Executive Compensation Committee and the Board

based on a comprehensive review of quantitative and qualitative factors designed to achieve long-term business success and competitiveness. Our

executive compensation program is designed to attract, motivate and retain the key executives who guide our success and who are leaders in the

industry, to reward individual and company performance and to align the long-term interests of our executive officers with those of our shareholders.

Our compensation philosophy and related governance features are summarized below.

●	●
WHAT WE DO	WHAT WE DON’T DO
Compensation Program Continuity — Our shareholders have provided strong support for our compensation program over the years. The components of our executive compensation program have remained substantially the same for several years. We believe our program is designed appropriately, is well aligned with the interests of our shareholders and is key to achieving our business goals. We periodically evaluate the effectiveness of our program and its alignment with our business strategy. Independent Committee Determination — Our Executive Compensation Committee, composed solely of independent directors, makes all compensation recommendations regarding each named executive officer ("NEO"). These recommendations are then submitted to the Board for its consideration and approval. Prudent Risk Management — The Committee designs compensation programs and sets compensation targets intended to discourage excessive risk-taking. Pay-for-Performance — A significant portion of the compensation for our named executive officers is in the form of at-risk, variable compensation based on company and individual performance, with a focus on creating long-term shareholder value. Competitive Compensation — In order to attract and retain qualified executives, our compensation programs provide a competitive overall total rewards opportunity. Multiple Performance Metrics — Variable compensation is based on more than one measure to encourage balanced incentives. Awards Are Capped — All of our variable compensation plans have caps on payouts. Retention-Based Incentives — A significant portion of total compensation is subject to multi-year vesting requirements. Share-Ownership Guidelines — We have market competitive share-ownership guidelines for our directors and officers. “Clawback” Provisions — We have adopted a clawback policy in compliance with Rule 10D-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the corresponding NYSE listing standards that require recovery of erroneously awarded compensation.

WHAT WE DO

WHAT WE DON’T DO

Compensation Program Continuity — Our shareholders have provided strong support for our compensation program over the years. The components of our executive compensation program have remained substantially the same for several years. We believe our program is designed appropriately, is well aligned with the interests of our shareholders and is key to achieving our business goals. We periodically evaluate the effectiveness of our program and its alignment with our business strategy. Independent Committee Determination — Our Executive Compensation Committee, composed solely of independent directors, makes all compensation recommendations regarding each named executive officer ("NEO"). These recommendations are then submitted to the Board for its consideration and approval. Prudent Risk Management — The Committee designs compensation programs and sets compensation targets intended to discourage excessive risk-taking. Pay-for-Performance — A significant portion of the compensation for our named executive officers is in the form of at-risk, variable compensation based on company and individual performance, with a focus on creating long-term shareholder value. Competitive Compensation — In order to attract and retain qualified executives, our compensation programs provide a competitive overall total rewards opportunity. Multiple Performance Metrics — Variable compensation is based on more than one measure to encourage balanced incentives. Awards Are Capped — All of our variable compensation plans have caps on payouts. Retention-Based Incentives — A significant portion of total compensation is subject to multi-year vesting requirements. Share-Ownership Guidelines — We have market competitive share-ownership guidelines for our directors and officers. “Clawback” Provisions — We have adopted a clawback policy in compliance with Rule 10D-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the corresponding NYSE listing standards that require recovery of erroneously awarded compensation. In addition to the mandatory clawback provisions, our clawback policy permits the discretionary recovery of incentive-based cash and any equity compensation in the event of fraud, negligence or intentional misconduct that directly or indirectly results in a material restatement of all or a portion of our financial statements. Tally Sheets — The Committee reviews total compensation tally sheets at least annually as part of making individual compensation decisions. Independent Consultant — The Committee engages a compensation consultant that is independent under the Securities and Exchange Commission rules and NYSE listing standards to provide advice and expertise on the design and implementation of our executive and director compensation programs. “Double Trigger” Vesting of Equity Awards in a Change in Control — Under our 2018 EIP, a change in control will not automatically trigger vesting of outstanding equity awards unless the acquirer does not assume or replace the outstanding awards. Rather, participants must experience a termination of employment without cause or resign for good reason within two years following a change in control for an award to vest.

Individual Employment Agreements — We do not enter into individual employment agreements with our named executive officers. No Hedging of Company Stock — Our securities/insider trading policy prohibits insiders, including our named executive officers, from engaging in hedging activities with respect to our stock. No Pledging of Company Stock — Our officers and directors may not hold our securities in a margin account or pledge our securities as collateral for a loan, subject to an exception that may be granted by our chief executive officer for loans (not margin accounts) that can be repaid without resorting to the pledged securities. No Tax Gross-ups — We do not provide tax gross-ups for change in control benefits. No Significant Perquisites — Our executive officers, including the named executive officers, receive no recurring significant perquisites or other personal benefits.

Summary Proxy Information

Key Components of Our Executive Compensation Program in

2024 Remain Unchanged

In designing our 2024 executive compensation program, our Executive Compensation Committee considered, among other factors, the strong shareholder approval at our 2024 annual meeting in favor (95.4% of the shares voted, including abstentions) of our 2023 executive compensation program and our executive pay practices. In view of this high level of shareholder support, the Executive Compensation Committee determined that no changes to the components of our executive compensation program were necessary in 2024. Our shareholders have provided consistently strong support for our compensation program since the inception of the say-on-pay advisory shareholder vote.

Alignment of Executive Compensation and Performance

We structure our executive compensation program to align the interests of our named executive officers with the interests of our shareholders. We

believe a named executive officer’s compensation should be tied directly to the achievement of our strategic, financial and operating goals, all of

which are designed to deliver value to our shareholders. Therefore, a significant part of each named executive officer’s pay is “at-risk,” in the form of

an annual, short-term, cash incentive award and long-term, equity-based incentive awards.

Our Board, upon the recommendation of our Executive Compensation Committee, awarded Mr. Norton incentive compensation for 2024 as our President and Chief Executive Officer, including payment of an annual short-term cash incentive award of $2,800,700 in recognition of his performance and leadership during the year and the grant of a long-term equity incentive award with a grant date target value of $8.0 million. Consistent with our executive compensation philosophy, a majority of Mr. Norton’s total direct compensation of approximately $11.7 million for 2024 was incentive-based and at-risk, as illustrated by the chart on the right. (For more details, see pages 83 - 84 , 93 .) 2024 CEO COMPENSATION

Consistent with our executive compensation philosophy, a majority of 2024 total direct compensation for our named executive officers other than Mr. Norton was incentive-based and at-risk, as illustrated by the chart on the right.

What if My Shares Are Held by My Broker or Similar Person?

If your shares are held in a brokerage account or by a similar person, your shares are considered to be held “in street name.” If you held shares in street

permitted to exercise their discretion to vote your shares only on the ratification of the selection of our independent registered public accounting firm

respond to their request for your voting instructions in a timely manner, your shares held through your broker or similar person will not be voted on

Please provide your voting instructions to your broker or similar person so that your shares may be voted.

• notifying our corporate secretary in writing;

• authorizing a later proxy via the internet or by telephone;

• returning a later-dated proxy card; or

• voting online at the meeting.

If your shares are held in a brokerage account or by a similar person, you may revoke any voting instructions you may have previously provided only

in accordance with revocation instructions provided by your broker or similar person.

Is My Vote Confidential?

Proxy cards, ballots and voting tabulations that identify individual shareholders are mailed and returned directly to our stock transfer agent who is

responsible for tabulating the vote in a manner that protects your voting privacy. It is our policy to protect the confidentiality of shareholder votes

throughout the voting process. The vote of any shareholder will not be disclosed to our directors, officers or employees, except:

• to meet legal requirements;

• to assert or defend claims for or against us; or

• in those limited circumstances where:

• a proxy solicitation is contested (which, to our knowledge, is not the case in connection with the 2025 annual meeting),

• a shareholder writes comments on a proxy card, or

• a shareholder authorizes disclosure.

The vote tabulator and the inspector of the election has been, and will remain, independent of us. This policy does not prohibit shareholders from

disclosing the nature of their votes to our directors, officers or employees, or prevent us from voluntarily communicating with our shareholders,

ascertaining which shareholders have voted or making efforts to encourage shareholders to vote.

Who Will Count the Vote?

Representatives of our stock transfer agent, Equiniti Trust Company, LLC will tabulate the votes and act as the inspector of the election.

How is Common Stock Held in Our 401(K) Plan Voted?

In order to vote shares of our common stock held through our 401(k) Plan, you must instruct the trustee of the 401(k) Plan, Fidelity Management

Trust Company, how to vote those shares by providing your instructions via the internet, by telephone or by mail in the manner outlined above. If you

fail to provide your instructions or if you return an instruction card with an unclear voting designation or with no voting designation at all, then the

trustee will vote the shares in your account in proportion to the way the other participants in the 401(k) Plan vote their shares. These votes receive

the same confidentiality as all other shares voted.

To allow sufficient time for voting by the trustee of our 401(k) Plan, your voting instructions must be received by 11:59 p.m. Central

Daylight Time on May 18, 2025 .

How Will Shares for Which a Proxy is Appointed Be Voted on

Any Other Business Conducted at the Annual Meeting That is

Not Described in This Proxy Statement?

Although we do not know of any business to be considered at the 2025 annual meeting other than the proposals described in this proxy statement, if

any other business is properly presented at the annual meeting, your proxy gives authority to Julie H. Edwards, Board Chair, and Lyndon C. Taylor,

Executive Vice President, Chief Legal Officer and Assistant Secretary, to vote your shares on such matters at their discretion.

What Shares Are Included on the Proxy Card(s)?

The shares included on your proxy card(s) represent all of the shares that you owned of record as of the close of business on March 24, 2025,

including those shares held in our Direct Stock Purchase and Dividend Reinvestment Plan , but excluding any shares held for your account by Fidelity

Management Trust Company, as trustee for our 401(k) Plan. If you do not authorize a proxy via the internet, by telephone or by mail, your shares,

except for those shares held in our 401(k) Plan, will not be voted. Please refer to the discussion above for an explanation of the voting procedures for

your shares held in our 401(k) Plan.

What Does It Mean if I Receive More Than One Proxy Card?

If your shares are registered differently and are in more than one account, you will receive more than one proxy card. Please sign and return all proxy

cards, or appoint a proxy via the internet or by telephone, to ensure that all your shares are voted. We encourage you to have all accounts registered

in the same name and address whenever possible.

Why Did We Receive Just One Copy of the Proxy Statement

and Annual Report When We Have More Than One Stock

Account in Our Household?

We have adopted a procedure approved by the Securities and Exchange Commission called “householding.” This procedure permits us to send a

single copy of the proxy statement and annual report to a household if the shareholders provide written or implied consent. Shareholders with

multiple accounts that share the same last name and household mailing address will receive a single copy of shareholder documents (annual report,

proxy statement, or other informational statement) unless we are instructed otherwise. Shareholders will continue to receive a separate proxy card

for each stock account. We previously mailed a notice to eligible registered shareholders stating our intent to utilize this rule unless the shareholder

provided an objection.

If you are a registered shareholder and received only one copy of the proxy statement and annual report in your household, we will promptly deliver

copies, to the extent you request them, for each member of your household who was a registered shareholder as of the record date. You may make

this request by calling EQ Shareowner Services at 1-866-235-0232 or by providing written instructions to EQ Shareowner Services,

Attn: Householding/ONEOK, Inc., P.O. Box 64854, St. Paul, Minnesota 55164-0854. You also may contact EQ Shareowner Services in the same

manner if you are currently receiving a single copy of the proxy statement and annual report in your household and desire to receive separate copies

in the future for each member of your household who is a registered shareholder or if your household is currently receiving multiple copies of the

proxy statement and annual report and you desire to receive a single copy in the future for your entire household.

If you are not a registered shareholder and your shares are held through a broker or similar person, you will need to contact that entity to revoke your

election and receive multiple copies of these documents.

Taylor were designated by the Board to serve as proxies.

To vote shares held “in street name” through a broker or similar person, a shareholder must provide voting instructions to them. Brokerage firms and

similar persons are required to request voting instructions for shares they hold on behalf of their customers and others. We encourage you to provide

instructions to your brokerage firm or similar person on how to vote your shares. If your shares are held “in street name,” to be able to vote those

shares online at the annual meeting, you must obtain a proxy, executed in your favor, from the broker or similar person who held those shares as of

the close of business on March 24, 2025.

The rules of the NYSE determine whether proposals presented at shareholder meetings are routine or non-routine. If a proposal is routine, a broker

or similar person holding shares for an owner in street name may vote for the proposal without receiving voting instructions from the owner under

certain circumstances. If a proposal is non-routine, the broker or similar person may vote on the proposal only if the owner has provided voting

instructions. A “broker non-vote” occurs when the broker or similar person is unable to vote on a proposal because the proposal is non-routine and

the owner has not provided voting instructions. Under the rules of the NYSE, Proposals 1, 3, 4, and 5 are considered to be non-routine, and

Proposal 2 is considered to be routine. Accordingly, if you do not provide voting instructions to your brokerage firm or similar person holding your

shares, they will not be permitted under the rules of the NYSE to vote your shares on Proposals 1, 3, 4, and 5, and they will be permitted to vote your

shares only on Proposal 2 at their discretion.

Please provide your voting instructions to your broker or similar person so that your shares may be voted.

Representatives of our stock transfer agent, Equiniti Trust Company, LLC will be responsible for tabulating and certifying the votes cast at

the meeting.

QUORUM

The holders of a majority of the shares entitled to vote at the annual meeting, present online or by proxy, constitute a quorum for the transaction of

business at the annual meeting. In determining whether we have a quorum, we count abstentions and broker non-votes as present.

If a quorum is not present at the scheduled time of the meeting, the shareholders who are present online or by proxy may adjourn the meeting until a

quorum is present. If the time and place of the adjourned meeting are announced at the time the adjournment is taken, no other notice need be

given. However, if the adjournment is for more than 30 days, or if a new record date is set for the adjourned meeting, notice will be given to each

shareholder entitled to receive notice of, and to vote at, the meeting.

VOTES REQUIRED

Proposal 1 – Election of Directors

Our By-laws provide for majority voting for directors in uncontested elections. We expect that the election of directors at our 2025 annual meeting will

be uncontested. Under the majority voting standard, the election of directors is decided by the affirmative vote of a majority of the votes cast with

respect to that nominee’s election by the shareholders present online or by proxy at the meeting and entitled to vote for the election of directors. In

other words, to be elected a nominee must receive a number of “for” votes that exceeds the number of “against” votes cast with respect to that

director’s election. Abstentions and broker non-votes, if any, do not count as “for” or “against” votes cast with respect to the election of directors.

Under Oklahoma law, if an incumbent director who is a nominee does not receive, in an uncontested election, the requisite majority vote to be

elected at an annual meeting, that director remains in office as a “holdover” director. However, our Corporate Governance Guidelines require that

such a director must promptly, following certification of the shareholder vote, tender his or her resignation to our Board. The Board, excluding the

director who tendered the resignation, will then evaluate the resignation in light of the best interests of our company and our shareholders in

determining whether to accept or reject the resignation, or whether other action should be taken. In reaching its decision, the Board may consider

any factors it deems relevant, including the director’s qualifications, the director’s past and expected future contributions to the company, the overall

composition of the Board and whether accepting the tendered resignation would cause the company to fail to comply with any applicable rule or

regulation (including NYSE listing requirements and the federal securities laws). The Board will act on the tendered resignation and publicly disclose

its decision and rationale within 90 days following certification of the shareholder vote.

Proposal 2 – Ratification of Selection of

PricewaterhouseCoopers LLP as our Independent

Registered Public Accounting Firm for the Year Ending

December 31, 2025

In accordance with our By-laws, approval of Proposal 2 requires the affirmative vote of a majority of the voting power of the shareholders present

online or by proxy and entitled to vote on the proposal at the meeting. Abstentions will have the same effect as votes against Proposal 2. If you do

not provide voting instructions to your brokerage firm or similar person holding your shares, they will be permitted to vote your shares on Proposal 2

at their discretion.

Proposal 3 – Approval of the ONEOK, Inc. 2025 Equity

Incentive Plan

In accordance with our By-laws, approval of Proposal 3 requires the affirmative vote of a majority of the voting power of the shareholders present

online or by proxy and entitled to vote on the proposal at the meeting. Abstentions will have the same effect as votes against Proposal 3. If you do

not provide voting instructions to your brokerage firm or similar person holding your shares, they will not be permitted to vote your shares on

Proposal 3. Broker non-votes do not count as shares entitled to vote for purposes of determining the outcome of the vote on Proposal 3.

Proposal 4 – Approval of the ONEOK, Inc. 2025 Employee

Stock Award Program

In accordance with our By-laws, approval of Proposal 4 requires the affirmative vote of a majority of the voting power of the shareholders present

online or by proxy and entitled to vote on the proposal at the meeting. Abstentions will have the same effect as votes against Proposal 4. If you do

not provide voting instructions to your brokerage firm or similar person holding your shares, they will not be permitted to vote your shares on

Proposal 4. Broker non-votes do not count as shares entitled to vote for purposes of determining the outcome of the vote on Proposal 4.

Proposal 5 – Advisory Vote on Executive Compensation

In accordance with our By-laws, approval of Proposal 5 requires the affirmative vote of a majority of the voting power of the shareholders present

online or by proxy and entitled to vote on the proposal at the meeting. Abstentions will have the same effect as votes against Proposal 5. If you do

not provide voting instructions to your brokerage firm or similar person holding your shares, they will not be permitted to vote your shares on

Proposal 5. Broker non-votes do not count as shares entitled to vote for purposes of determining the outcome of the vote on Proposal 5.

REVOKING A PROXY

Any shareholder may revoke his or her proxy at any time before it is voted at the meeting by (i) notifying our corporate secretary in writing (the

mailing address of our corporate secretary is 100 West Fifth Street, Tulsa, Oklahoma 74103), (ii) authorizing a later proxy via the internet or by

telephone, (iii) returning a later dated proxy card or (iv) voting online at the meeting. A shareholder’s presence without voting at the annual meeting

will not automatically revoke a previously delivered proxy and any revocation during the meeting will not affect votes previously taken at the meeting.

If your shares are held by a brokerage firm or similar person, you may revoke any voting instructions you may have previously provided in

accordance with the revocation instructions provided by the broker or similar person.

PROXY SOLICITATION

S olicitation of proxies will be primarily by mail and telephone. We have engaged Sodali & Co, 333 Ludlow St., 5th Floor, South Tower, Stamford,

Connecticut 06902, to solicit proxies for a fee of $11,000, plus out-of-pocket expenses . In addition, certain of our officers, directors and employees

may solicit proxies on our behalf in person or by mail, telephone, fax or email, for which such persons will receive no additional compensation. We

will pay all costs of soliciting proxies. We will also reimburse brokerage firms, banks and other custodians, nominees and fiduciaries for their

reasonable expenses in forwarding proxy materials to our shareholders.

In connection with our solicitation of proxies for our 2026 annual meeting, we intend to file a proxy statement and WHITE proxy card with the

Securities and Exchange Commission. Shareholders may obtain our proxy statement (and any amendments and supplements thereto) and other

documents as and when filed with the Securities and Exchange Commission without charge from the Securities and Exchange Commission’s

website at: www.sec.gov .

GOVERNANCE OF THE COMPANY

Our Board and management are committed to maintaining strong corporate governance practices that allocate rights and responsibilities among our

Board, management and shareholders in a manner that benefits the long-term interest of our shareholders. Our corporate governance practices are

designed not only to satisfy regulatory and stock exchange requirements, but also to provide for effective oversight and management of

our company.

Our Corporate Governance Committee engages in a regular process of reviewing our corporate governance practices, including comparing our

practices with those recommended by various corporate governance authorities, the expectations of our shareholders and the practices of other

leading public companies. Our Corporate Governance Committee also regularly reviews our corporate governance practices in light of proposed and

adopted laws and regulations, including the rules of the Securities and Exchange Commission and the rules and listing standards of the NYSE.

CORPORATE GOVERNANCE GUIDELINES

Our Board has adopted Corporate Governance Guidelines that address key areas of our corporate governance, including, among others: the Board’s

mission and responsibilities; Board membership and leadership; the structure and function of the Board’s committees; meetings of the Board and its

committees, including attendance requirements and executive sessions; Board compensation; Board and officer share-ownership requirements;

succession planning; evaluation of the performance of our Board; and Board access to management and independent advisors. Our Board annually

reviews our Corporate Governance Guidelines and may revise the guidelines from time to time as conditions warrant. The full text of our Corporate

Governance Guidelines is published on and may be printed from our website at www.oneok.com and is also available from our corporate secretary

upon request.

CODE OF BUSINESS CONDUCT AND ETHICS

The foundation of our Code of Business Conduct and Ethics ("Code"), titled “ONE Way to Work,” is built upon our core values. Directors, officers

(including our principal executive and financial officers, principal accounting officer, controllers and other persons performing similar functions) and

employees are required to adhere to our Code in addressing the legal and ethical issues encountered in conducting their work for our company. The

Code covers subjects such as workplace conduct, insider trading and conflicts of interest, inclusion, environmental protection and sustainability,

health and safety at work, community support and human rights, use of company assets, confidential information and intellectual property, data

privacy, fair competition, anti-bribery and anti-corruption, gifts and entertainment, financial integrity and government interactions, among others. The

Code is fully digital and interactive allowing directors, officers and employees to easily navigate to other relevant company policies or to report

violations of the Code.

All employees, directors and officers are required annually to complete Code training and to certify that they are in compliance with the Code and are

not aware of any non-compliance. In addition, they are required to report any conduct that they believe to be an actual or apparent violation of our

Code.

The full text of our Code is published on and may be printed from our website at www.oneok.com and is also available from our corporate secretary

Governance of the Company

BUSINESS PARTNER CODE OF CONDUCT

Our business partners, whether a supplier, consultant, vendor, contractor, agent or other third-party provider, act as an extension of our business

and share the responsibility to work ethically and to continually reflect our Mission, Vision and Core Values. Accordingly, the company implemented a

Business Partner Code of Conduct (“Business Partner Code”), titled “ONE Way to Partner,” to help guide our business partners throughout our

partnership. ONEOK expects all business partners to comply with the Business Partner Code and with all applicable laws, regulations, guidelines

and industry standards.

The Business Partner Code addresses topics such as health and safety, workforce inclusion, conflicts of interest, anti-bribery and anti-corruption,

and human rights. It is also fully digital and interactive allowing business partners to easily navigate content.

Our business partners are provided the Business Partner Code and must acknowledge their compliance. Business partners are encouraged to

contact ONEOK Compliance and Ethics or the ONEOK Hotline with questions or concerns and may do so anonymously.

The full text of our Business Partner Code is published on and may be printed from our website at www.oneok.com .

DIRECTOR INDEPENDENCE

Our Corporate Governance Guidelines provide that a majority of our Board will be “independent” under the applicable independence requirements of

the NYSE. These guidelines and the rules of the NYSE provide that, in qualifying a director as “independent,” the Board must make an affirmative

determination that the director has no material relationship with our company, either directly or as a partner, shareholder or officer of an organization

that has a relationship with our company. In making this determination with respect to each director serving on the Executive Compensation

Committee, the Board is required, under the rules of the NYSE, to consider all factors specifically relevant to determining whether the director has a

relationship with our company that is material to that director’s ability to be independent from management in connection with the duties of a member

of that committee.

Our Board has also adopted Director Independence Guidelines that specify the types of relationships the Board has determined to be categorically

immaterial. Directors who meet these standards are considered to be “independent.” The full text of our Director Independence Guidelines is

published on and may be printed from our website at www.oneok.com and is also available from our corporate secretary upon request.

Our Board has determined affirmatively that Board members Brian L. Derksen, Julie H. Edwards, Lori A. Gobillot, Mark W. Helderman, Randall J.

Larson, Pattye L. Moore, Eduardo A. Rodriguez, Gerald B. Smith, and Wayne T. Smith have no material relationship with our company, and each

qualifies as “independent” under our Corporate Governance Guidelines, our Director Independence Guidelines and the rules of the NYSE.

Accordingly, nine out of our ten directors as of the date of this proxy statement qualify as independent.

The Board also previously determined that Steven J. Malcolm and Jim W. Mogg each qualified as “independent” under our Corporate Governance

Guidelines, our Director Independence Guidelines and the rules of the NYSE for the period in which they served as directors during 2024.

BOARD LEADERSHIP STRUCTURE

During 2024, our Board was led by Julie H. Edwards, our independent Board Chair.

Ms. Edwards is the first female Board Chair in the company’s 119-year history.

Our Audit Committee, Corporate Governance Committee and Executive Compensation Committee were each led by a chair, each of whom is an

independent director.

Our Corporate Governance Guidelines provide that the Board retains the authority, in the exercise of its discretion, to combine or separate the offices

of Board Chair and Chief Executive Officer. Our Board reviews the issue as a part of its succession-planning process, based on the individuals then

available and the circumstances then presented. The Board believes it is advantageous for the Board to maintain the flexibility to determine the issue

on a case-by-case basis and, if necessary, to change the Board leadership structure at any time if it determines doing so is in the best interests of

our company and our shareholders.

Governance of the Company

LEAD INDEPENDENT DIRECTOR

Our Corporate Governance Guidelines provide that if the offices of the Board Chair and the Chief Executive Officer are combined, or if the company

has a non-independent Board Chair, or in the absence of a Board Chair, then the Chair of the Corporate Governance Committee, who shall have

served as a director for a minimum of three years, shall serve as the lead independent director. Our guidelines also specify the duties of the lead

independent director. In addition, the lead independent director has the authority to call meetings of the independent directors and, if requested by

major shareholders, will be made reasonably available by the company for consultation and direct communication with such shareholders.

With Ms. Edwards serving as independent Board Chair, the company does not currently have a lead independent director.

BOARD REFRESHMENT

Our Corporate Governance Committee and Board are continuously and actively engaged in board recruitment activities, with such topic being

discussed at 17 committee or Board meetings since February 2022 .

Attributes important in consideration of potential director candidates include, among others, leadership/chief executive officer experience, board or

related energy industry knowledge, and transformational thinking.

Board recruitment activities include, but are not limited to, collecting and reviewing names and biographical information of numerous potential director

candidates, eliminating many due to obvious conflicts and other factors, and prioritizing the remaining potential director candidates.

CEO AND SENIOR MANAGEMENT

SUCCESSION PLANNING

A key responsibility of the chief executive officer and the Board is ensuring that an effective process is in place to provide continuity of leadership

over the long-term at all levels in our company. Each year, succession-planning reviews are held at significant organizational levels of the company,

culminating in a full review of senior leadership talent by our independent directors. During this review, the chief executive officer, the Board Chair

and the independent directors discuss future candidates for senior leadership positions, succession timing for those positions and development plans

for the highest-potential candidates. This process ensures continuity of leadership over the long-term, and it forms the basis on which our company

makes ongoing leadership assignments.

CORPORATE STRATEGY

Our Board is actively involved in overseeing, reviewing and guiding our corporate strategy. Our Board formally reviews our company’s business

strategy, including the risks and opportunities facing our company and its businesses, at an annual strategic planning session. In addition, long-range

strategic issues, including the performance and strategic fit of our businesses, are discussed as a matter of course at regular Board meetings. Our

Board regularly discusses corporate strategy with management throughout the year, formally as well as informally, and during executive sessions of

the Board as appropriate. As discussed in “Risk Oversight” below, our Board views risk management and oversight as an integral part of our

strategic planning process, including mapping key risks to our corporate strategy and seeking to manage and mitigate risk. Our Board also views its

own composition as a critical component to effective strategic oversight. Accordingly, our Board and relevant Board committees consider our

business strategy and the company’s regulatory, geographic and market environments when assessing Board composition, director succession,

executive compensation and other matters of importance.

2025 ONEOK, Inc. Proxy Statement 29

Governance of the Company

SHAREHOLDER ENGAGEMENT

Our Board believes that accountability to shareholders is a mark of good corporate governance and that regular shareholder engagement is

important to our company’s success. Our company’s management team and investor relations department frequently engage with shareholders on a

variety of topics, with particular focus on matters relating to our company’s publicly disclosed strategy and financial performance. During 2024,

members of our management team and our investor relations department participated in approximately 20 investor conferences or events and held

approximately 450 discussions with investment firms.

Our management team and investor relations department also engage with shareholders to discuss matters relating to governance, compensation,

safety, the environment, social responsibility and other current and emerging issues that the Board and our management understand are important to

our shareholders. In addition to this direct engagement, our company also maintains a number of complementary mechanisms that allow our

shareholders to effectively communicate with our Board, including:

• Conducting the election of directors annually with a majority voting standard;

• Conducting an annual advisory vote to approve executive compensation;

• Maintaining an investor relations website;

• Regular meetings by our management team and investor relations department with investors and analysts;

• If requested by major shareholders, the Board Chair, lead independent director or other independent director will be made reasonably available

by the company for consultation and direct communication;

• Permitting shareholders to submit recommendations of prospective candidates for nomination by our Board for election at the annual meeting of

shareholders in accordance with our Corporate Governance Guidelines;

• Permitting shareholders to nominate candidates for election at the annual meeting of shareholders in accordance with our By-laws;

• Permitting proxy access by eligible shareholders in accordance with our By-laws; and

• Providing shareholders the ability to attend and voice opinions at the annual meeting of shareholders.

RISK OVERSIGHT

Enterprise Risk Management

We engage in an annual comprehensive ERM process designed to identify and manage risk. Our annual ERM assessment is designed to enable our

Board to establish a mutual understanding with management of the effectiveness of our risk-management practices and capabilities, to review our

risk exposure and to elevate certain key risks for discussion at the Board level. Risk management is an integral part of our annual strategic planning

process, which addresses, among other things, the risks and opportunities facing our company.

Our ERM program is overseen by our chief financial officer. The program is designed to identify, assess, monitor and manage risks that could affect

our ability to fulfill our business objectives or execute our corporate strategy. Our ERM process encompasses the identification and assessment of a

broad range of risks and the development and implementation of plans to mitigate these risks. Such risks generally relate to strategic, operational,

financial, regulatory compliance, climate-related considerations, ESG, cybersecurity and human capital management aspects of our business.

Not all risks can be dealt with in the same way. Some risks may be easily perceived and controllable. Other risks are unknown. Some risks can be

avoided or mitigated by particular behavior, and some risks are unavoidable as a practical matter. For some risks, the potential adverse impact would

be minor and, as a matter of business judgment, it may not be appropriate to allocate significant resources to avoid the risk. In other cases, the

potential adverse impact could be significant, and it is prudent to expend resources to seek to avoid or mitigate the risk. Management is responsible

for identifying risk and risk controls related to our significant business activities; mapping the risks to our corporate strategy; and developing

programs and recommendations to determine the sufficiency of risk identification, the balance of potential risk to potential reward and the appropriate

manner in which to control and mitigate risk.

The Board implements its risk-oversight responsibilities by having management provide periodic briefing and informational sessions on the significant

risks our company faces and the ways in which our company is seeking to control and mitigate those risks. In some cases, as with risks relating to

significant acquisitions, risk oversight is addressed as part of the full Board’s ongoing engagement with the chief executive officer and management.

30 2025 ONEOK, Inc. Proxy Statement

Governance of the Company

The Board annually reviews a management assessment of the various operational and regulatory risks facing our company, their relative magnitude

and management’s plan for mitigating these risks. This review is conducted in conjunction with the Board’s review of our company’s business

strategy at its annual strategic planning meeting and at other meetings as appropriate.

Management Risk Oversight and Strategy Committee

We also maintain a Risk Oversight and Strategy Committee, which consists of members of our senior management. This committee is responsible

for ensuring that our exposure to commodity price and interest rate risks, as well as risks associated with marketing, trading, hedging practices, and

long-term contractual commitments are monitored within the framework established by our company policies. The committee is also responsible for

developing and implementing marketing and hedging strategies designed to mitigate or manage those risks within acceptable risk thresholds.

Board Committee Risk Oversight

In certain cases, a Board committee is responsible for oversight of specific risk topics. For example, the Audit Committee oversees risk issues

associated with our overall financial reporting and disclosure process and legal compliance, as well as reviewing policies and procedures on risk

control assessment and accounting-risk exposure, including our companywide risk control activities. The Audit Committee meets with our chief

financial officer, chief enterprise services officer, chief accounting officer, chief legal officer, and our vice president, audit services, as well as with our

independent registered public accounting firm, in separate executive sessions at least three times during the year at which meetings risk issues are

discussed regularly.

In addition, our Executive Compensation Committee oversees risks related to our compensation programs, as discussed in greater detail elsewhere

in this proxy statement, and our Corporate Governance Committee oversees risks related to our governance practices and policies.

ESG OVERSIGHT

Our Board provides key leadership, guidance and diverse energy industry and business expertise as it oversees executive management’s

development and implementation of the company’s ESG practices. This oversight includes regular engagement with and updates by our CEO,

executive management and others.

Our Board also conducts a biannual examination of the company’s ESG practices, performance, risks and opportunities. Such examinations have

been incorporated into the company’s Audit Committee Charter, as amended and restated February 21, 2024, and are scheduled to take place at the

Board’s February and August meetings.

In 2024, these examinations covered topics such as environmental, safety and health performance, mechanical integrity, process safety, integration

and continuous improvement plans, GHG emission trends, GHG emissions reduction performance, new regulatory requirements, ESG-related

shareholder engagements, ESG performance, risks and opportunities.

For more information regarding the Board’s ESG oversight, the company’s sustainable governance structure, and the associated roles and

responsibilities various groups and/or individuals play within that structure, see pages 42 - 47 .

HUMAN CAPITAL MANAGEMENT OVERSIGH T

Our Board provides key leadership, guidance and diverse energy industry and business expertise as it oversees executive management’s

development and implementation of the company’s human capital management practices. This oversight includes regular engagement with, and

updates by, our CEO, executive management and others.

Our Board also conducts a biannual examination of the company’s human capital management practices, performance, risks and opportunities. Such

examinations have been incorporated into the company’s Executive Compensation Committee Charter, as amended and restated February 21,

2024, and are scheduled to take place at the Board’s regular February and August meetings.

In 2024, these examinations covered topics such as workforce inclusion, people, culture, talent recruitment, integration, engagement, development,

succession, employee benefits, business resource groups, community, awards and recognition.

CYBERSECURITY AND PHYSICAL SECURITY

Protecting Our Assets

ONEOK takes a cross-disciplinary approach to cybersecurity and physical security. We use systems and procedures designed to protect our physical

and cyber assets as well as to enhance business continuity and disaster recovery preparedness.

Securing company assets is critical to ONEOK’s commitments to:

• Provide safe work environments for employees and contractors.

• Protect the personal information of its employees, contractors and customers.

• Act as a responsible member of the communities where we operate.

• Provide reliable service to customers.

• Create value for stakeholders.

Security Leadership and Governance

Security is governed by the Security Advisory Team, an executive advisory committee composed of company officers, including our chief executive

officer, our chief financial officer and our chief enterprise services officer. The Security Advisory Team meets regularly to evaluate ongoing security

threats and incidents, to define policy and to prioritize initiatives. Identified cybersecurity threats and incidents are monitored and assessed for

materiality by this cross-functional Security Advisory Team. This assessment includes whether our Board should be informed of a threat or incident.

The Security Advisory Team is chaired by our vice president of cybersecurity and physical security who has more than twenty years of relevant

experience in the field of cyber and physical security. In his role, our vice president of cybersecurity and physical security also supervises efforts to

prevent, detect, mitigate and remediate cybersecurity risks and incidents through various means, which include briefings from internal security

personnel, alerts and reports produced by security tools deployed in our technology infrastructure and threat intelligence and other information

obtained from governmental, public or private sources, including external cybersecurity service providers. Our vice president of cybersecurity and

physical security reports to our executive vice president and chief enterprise services officer, responsible for cybersecurity, information technology,

enterprise optimization and innovation, among other responsibilities. Before joining ONEOK, our executive vice president and chief enterprise

services officer held information technology positions of increasing responsibility.

Cybersecurity risks are communicated and discussed with our Board at least annually in conjunction with our overall ERM program. Internal Audit

provides periodic updates to the Audit Committee on testing completed to meet TSA requirements. As part of its oversight responsibilities, our Board

also receives frequent updates from executive management on our company’s physical and cybersecurity efforts.

Cybersecurity

Our annual ERM process encompasses the identification and assessment of a broad range of risks, including cybersecurity, and the development

and testing of controls to mitigate these risks. Our ERM assessment is designed to enable our Board to establish a mutual understanding with

management of the effectiveness of our risk-management practices and capabilities, to review our risk exposures and to elevate certain key risks for

discussion at the Board level. Our ERM program is overseen by our chief financial officer.

Our cybersecurity risk management program is integrated with our ERM program and shares common methodologies, reporting channels and

governance processes that apply across the ERM program to other legal compliance, strategic, operational and financial risk areas. Our security

program generally incorporates the guidelines of the widely utilized National Institute of Standards and Technology Cybersecurity Framework, though

this does not imply we meet any particular technical standards, specifications or requirements. In addition, we conduct risk assessments of enterprise

third-party software and cloud vendors by utilizing security questionnaires prior to procurement. On a regular basis, we engage consultants, including

external counsel and cybersecurity firms, to conduct penetration tests and architecture design reviews.

As of the date of this proxy, though the company and third parties have experienced certain non-material cybersecurity incidents, we are not aware

of any cybersecurity threats, that have materially affected or are reasonably likely to materially affect us, including our business strategy, results of

operations or financial condition. We face certain ongoing risks from cybersecurity threats that, if realized and material, may materially affect us,

including our operations, business strategy, results of operations or financial condition. See Part 1, Item 1A “Risk Factors” for a discussion of risk

factors related to cybersecurity in our Annual Report on Form 10-K for the year ended December 31, 2024.

Critical Infrastructure Security

ONEOK is an essential critical infrastructure business, and cybersecurity is a top priority for our company's leadership and Board. Much of the

cybersecurity surrounding our critical infrastructure environment is regulated by the TSA through specific pipeline security directives and regular

inspections by the agency.

Physical Security

ONEOK implements a risk-based physical security program focused on the protection of people and assets. This includes participation in the TSA's

Pipeline Security Guidelines and collaboration with a number of agencies at a federal, state, and local level. ONEOK also uses technology as part of

its physical security strategy. This includes video surveillance, as well as access control systems that limit facility and office entry to approved

individuals and provide a record of individuals in a workspace at any given time. ONEOK has standardized physical security technology across our

operations, including deploying common ID-badge technology.

Employee and Contractor Security Training

We provide training to help employees and contractors recognize and avoid potential security threats, and all employees are required to complete

annual, job specific security training.

Security training examples:

• Industrial Control Systems (ICS): Employees operating and monitoring ONEOK ICS assets are required to complete training on specific threat

indicators in the ICS environment and practices for identifying and responding to threats.

• Health Insurance Portability and Accountability Act (HIPAA): ONEOK requires training on the policies and procedures it maintains to

safeguard protected health information (PHI) in accordance with HIPAA. All individuals who may have access to PHI are required to complete

annual training and maintain other physical, technological, and procedural safeguards.

• SecuritySense Program: All employees are encouraged to participate in a monthly training course that covers a variety of security topics such

as active shooter awareness, phishing awareness, ransomware recognition and prevention, and physical security at ONEOK facilities.

Crisis Management and Resiliency

ONEOK maintains detailed procedures covering crisis management, emergency response and incident communication, and conducts drills to

practice and evaluate crisis response efforts. Drills provide ONEOK and participating authorities an opportunity to test crisis response preparedness,

coordinate efforts and identify areas for improvement.

Acquisitions

ONEOK’s integration efforts are ongoing with respect to cybersecurity and physical security platforms of the companies we acquired since

September 2023.

BOARD AND COMMITTEE MEMBERSHIP

Our business, property and affairs are managed under the direction of our Board. Members of our Board are kept informed of our business through

discussions with our chief executive officer and other officers, by reviewing materials provided to them periodically and in connection with Board and

committee meetings, by visiting our offices and our operating facilities and by participating in meetings of the Board and its committees.

During 2024, the Board (including its committees) held 21 regular meetings and nine special meetings . At times during 2024, such meetings were

held in-person, telephonically and virtually. Each of our incumbent directors who served on the Board d uring 2024 attended at least 92% o f the

aggregate of all meetings of the Board and Board committees on which they served in 2024.

Our Corporate Governance Guidelines provide that all members of our Board are expected to attend our annual meeting of shareholders. All

members of our Board attended the 2024 annual meeting of shareholders, which was held virtually.

Governance of the Company

The Board has three standing committees consisting of the Audit Committee, the Executive Compensation Committee and the Corporate

Governance Committee. These standing committees met in-person, telephonically and virtually at times during 2024. Our Corporate Governance

Committee annually reviews the composition and membership of each standing committee of the Board, and such a review took place in May 2024.

Unless otherwise specified, standing committee membership references herein reflect the period May through December 2024.

Our Board has adopted written charters for each of its Audit, Executive Compensation and Corporate Governance Committees. Copies of these

committee charters are available on and may be printed from our website at www.oneok.com . Copies are also available from our corporate secretary

upon request. The primary responsibilities of our standing committees are summarized below. The Board, in its discretion, may form

other committees.

DIRECTOR NOMINATIONS

Our Corporate Governance Guidelines provide that the Board is responsible for selecting candidates for Board membership, and the screening

process is delegated to the Corporate Governance Committee. The Corporate Governance Committee, with recommendations and input from our

Board Chair, our chief executive officer and members of our Board, evaluates the qualifications of each director candidate and assesses the

appropriate mix of skills, qualifications and characteristics required of Board members in the context of the perceived needs of the Board at a given

point in time. The Corporate Governance Committee is responsible for recommending candidates for nomination by the Board for election as

members of our Board.

Our Corporate Governance Guidelines provide that candidates for nomination by the Board must be committed to devoting the time and effort

necessary to be productive members of the Board and that , in nominating candidates, the Board will endeavor to maintain a mix of viewpoints and

experiences that includes, but is not limited to, the following areas of core competency: accounting and finance; investment banking; business

judgment; management; energy industry knowledge; crisis response; international business; leadership; strategic vision; technology; law; and

corporate relations.

The Corporate Governance Committee’s charter provides that it has the responsibility, in consultation with the Board Chair and the chief executive

officer, to search for, recruit, screen, interview and select candidates for the position of director as necessary to fill vacancies on the Board or the

additional needs of the Board and to consider management and shareholder recommendations for candidates for nomination by the Board. In

carrying out this responsibility, the Corporate Governance Committee evaluates the qualifications and performance of incumbent directors and

determines whether to recommend them for election to the Board. In addition, the Corporate Governance Committee determines, as necessary, the

portfolio of skills, experience, perspective and background required for the effective functioning of the Board considering our business strategy and

our regulatory, geographic and market environments.

36 2025 ONEOK, Inc. Proxy Statement

Governance of the Company

Our Corporate Governance Guidelines contain a policy regarding the Corporate Governance Committee’s consideration of prospective director

candidates recommended by shareholders for nomination by our Board. Pursuant to this policy, any shareholder who wishes to recommend a

prospective candidate for nomination by our Board for election at our 2026 annual meeting should send a letter of recommendation to our corporate

secretary at our principal executive offices no later than September 30, 2025.

The letter should include the name, address and number of shares owned by the recommending shareholder (including, if the recommending

shareholder is not a shareholder of record, proof of ownership of the type referred to in Rule 14a-8(b)(2) of the Exchange Act); the prospective

candidate’s name and address; a description of the prospective candidate’s background, qualifications, and relationships, if any, with our company;

and all other information necessary for our Board to determine whether the prospective candidate meets the independence standards under the rules

of the NYSE and our Director Independence Guidelines. A signed statement from the prospective candidate should accompany the letter of

recommendation indicating that he or she consents to being considered as a nominee of the Board and, if nominated by the Board and elected by

the shareholders, he or she will serve as a director. The Corporate Governance Committee will evaluate prospective candidates recommended by

shareholders for nomination by our Board in light of the various factors set forth above.

Neither the Corporate Governance Committee, the Board, nor the company discriminate in any way against prospective candidates for nomination by

the Board on the basis o f personal background, race and ethnicity, gender, age and nationality . There are no differences in the manner in which the

Corporate Governance Committee or the Board evaluates prospective candidates based on whether the prospective candidate is recommended by a

shareholder or by the Corporate Governance Committee, provided that the recommending shareholder timely furnishes to our company a letter of

recommendation containing the information described above along with the signed statement of the prospective candidate referred to above.

In addition to having the ability to recommend prospective candidates for nomination by our Board, under our By-laws, shareholders may themselves

nominate candidates for election at an annual meeting of shareholders so long as they are shareholders of record when they give the notice

described below and on the record date for the relevant annual meeting. Any shareholder who desires to nominate candidates for election as

directors at our 2026 annual meeting must follow the procedures set forth in our By-laws. Under these procedures, notice of a shareholder

nomination for the election of a director must be received by our corporate secretary at our principal executive offices not less than 120 calendar

days, and not more than 150 calendar days, before the first anniversary of the date that our proxy statement was released to shareholders in

connection with our 2025 annual meeting of shareholders (i.e., notice must be received no earlier than November 3, 2025 and no later than

December 3, 2025) . If the date of the 2026 annual meeting is more than 30 days after May 21, 2026, the first anniversary of our 2025 annual

meeting, our corporate secretary must receive notice of a shareholder nomination by the close of business on the tenth day following the earlier of

the day on which notice of the date of the 2026 annual meeting is mailed to shareholders, or the day on which public announcement of the 2026

annual meeting date is made. In addition, in accordance with our By-laws, the shareholder notice must contain certain information about the

candidate the shareholder desires to nominate for election as a director, the shareholder giving the notice, and the beneficial owner, if any, on whose

behalf the nomination is made. Any notice of director nomination submitted to the company other than through proxy access must include the

additional information required by Rule 14a-19(b) under the Exchange Act.

In addition, our By-laws permit a shareholder, or a group of up to 20 shareholders, owning 3% or more of ONEOK’s common stock continuously for a

period of at least three years, to nominate for election to our Board and have such director nominations included in our proxy materials, a number of

director candidates equal to the greater of (i) two individuals or (ii) the closest whole number that does not exceed 20% of our Board, provided that

the shareholder(s) and the nominee(s) satisfy certain requirements specified in the By-laws. Under the applicable procedures, notice must be

received by our corporate secretary at our principal executive offices not less than 120 calendar days, and not more than 150 calendar days, before

the first anniversary of the date that our proxy statement was released to shareholders in connection with our 2025 annual meeting of shareholders

(i.e., for a nomination to be included in our 2026 proxy materials, notice must be received no earlier than November 3, 2025 and no later than

December 3, 2025). In accordance with our By-laws, the shareholder notice must contain certain information about the candidate the shareholder(s)

desire(s) to nominate for election as a director, the shareholder(s) giving the notice, and the beneficial owner(s), if any, on whose behalf the

nomination is made.

DIRECTOR COMPENSATION

The Executive Compensation Committee reviews director compensation on an annual basis in consultation with Meridian Compensation Partners,

the Committee’s independent compensation consultant. This review includes consideration of director compensation data compiled by Meridian

Compensation Partners for the same peer group used to assess compensation for our executive officers in order to assess the competitive levels

and types of compensation for our directors. We refer to this peer group as our “Energy Peers,” as discussed in further detail in the Compensation

Discussion & Analysis. In addition to considering director compensation data compiled by Meridian Compensation Partners, the Committee also

considers relevant factors, such as our company’s financial and operational performance, when reviewing director compensation. After completing its

review, the Committee submits its recommendation for director compensation to the full Board for approval.

Following its review in February 2024, the Committee recommended, and the full Board approved, the changes to the compensation paid to each of

our non-management directors shown in the table below, which were effective as of May 1, 2024. Changes to director compensation during 2024

were intended to align average total compensation with the market median when compared to our Energy Peers. Prior to this increase, d irector

compensation was last increased in Febru ary 2022.

Committee Chair Cash Retainers — Audit	$ 25,000
Executive Compensation	$ 20,000
Corporate Governance	$ 20,000

Committee Chair Cash Retainers — Audit	$ 25,000
Executive Compensation	$ 20,000
Corporate Governance	$ 20,000

(1) Directors may elect to receive cash retainers, including committee chair retainers, in fully vested shares of common stock.

(2) The number of shares of common stock issued for the annual stock retainer is determined based on the closing price of our company’s common stock on the

NYSE on the date of the Board meeting immediately following the company’s annual shareholder meeting.

All directors are reimbursed for reasonable expenses incurred in connection with attendance at Board and committee meetings.

Our one management director, Pierce H. Norton II, receives no compensation for his service as a director.

Our Board has established minimum share-ownership guidelines for members of our Board that provide that, within five years after joining the Board,

each non-management director will own shares of our common stock having a minimum value of five times the annual cash retainer paid for service

on our Board. Our share-ownership guidelines provide that a director may not sell shares of his or her stock unless such director holds shares that

meet the minimum ownership guidelines after giving effect to such sale. All directors were in compliance with these guidelines in 2024 . Our

shareholder-approved 2018 EIP imposes meaningful caps on the value of stock awards granted to our directors each year.

(1) Mr. Helderman elected to receive fully vested shares of common stock in lieu of the c ash retainer, and accordingly was issued 1,347 shares of our common stock

with a grant date fair value of $81.66, which shares were fully vested when granted. Fr actional shares are rounded down to the nearest whole share, with the

difference being paid in cash. Non-management directors may defer all or a part of their annual cash and stock retainers under our Deferred Compensation Plan

for Non-Employee Directors. During the year ended December 31, 2024, $884,000 of the total amount payable for directors’ fees was deferred under this plan at

the election of six of our directors. Deferred amounts are treated, at the election of the participating director, either as phantom stock or as a cash deferral.

Phantom stock deferrals are treated as though the deferred amount is invested in our common stock based on the closing price on the NYSE on the date the

deferred amount was earned. Phantom stock earns the equivalent of dividends declared on our common stock, reinvested in phantom shares of our common

stock based on the closing price of our common stock on the payment date of each common stock dividend. The shares of our common stock reflected in a non-

management director’s phantom stock account under our Deferred Compensation Plan for Non-Employee Directors are issued to the director on the last day of the

director’s service as a director or a later date selected by the director. Cash deferrals earn interest at a rate equal to Moody’s seasoned AAA corporate bond yield

index on the first business day of the plan year plus 100 basis points. At January 2, 2024, Moody’s rate was 4.75% ; therefore, cash deferrals in 2024 earned

interest at a rate of 5.75%. Cash deferrals are paid to the director on the last day of the director’s service as a director or at a later date selected by the director.

The following table sets forth, for each non-management director during 2024, the amount of director compensation deferred during 2024 and cumulative deferred

compensation as of December 31, 2024.

(b) Dividend equivalents paid on phantom stock are reinvested in additional shares of phantom stock (with the number of shares of common stock calculated

based on the closing price of our common stock on the NYSE on the date the dividend equivalent was paid.)

(c) The amounts for Ms. Edwards and Ms. Moore reflect interest accrued on prior cash deferrals. No board fees were deferred to cash in 2024 by Ms. Edwards or

Ms. Moore. Cash deferrals earn interest at a rate equal to Moody’s seasoned AAA corporate bond yield index on the first business day of the plan year plus

100 basis points. At January 2, 2024, Moody’s rate was 4.75%; therefore, cash deferrals in 2024 earned interest at a rate of 5.75% . Cash deferrals are paid to

the director on the last day of the director’s service as a director or at a later date selected by the director.

(2) The amounts in this column reflect the aggregate grant date fair value, computed in accordance with the Financial Accounting Standards Board’s Accounting

Standards Codification Topic 718, Compensation-Stock Compensation (“ASC Topic 718”), with respect to stock awards received by directors for service on our

Board. Each of our non-management directors was issued 2,082 shares of our common stock with a grant date fair value of $81.66 during 2024 for service on our

Board, which shares were fully vested when granted. Fractional shares are rounded down to the nearest whole share, with the difference being paid in cash.

However, if a non-management director defers all or part of his or her annual stock retainer under our Deferred Compensation Plan for Non-Employee Directors,

the value of fractional shares is reflected in the amount deferred to phantom stock.

of interest on cash deferrals at a rate equal to Moody’s seasoned AAA corporate bond yield index on the first business day of the plan year plus 100 basis points.

At January 2, 2024, Moody’s rate was 4.75%; therefore, cash deferrals in 2024 earned interest at a rate of 5.75%. Cash deferrals are paid to the director on the

last day of the director’s service as a director or at a later date selected by the director.

(5) Reflects charitable contributions made by our company or the ONEOK Foundation, Inc., on behalf of members of our Board as follows: (a) a $1,000 annual

pursuant to our Board matching grant program; and (c) matching contributions to the United Way pursuant to our annual United Way contribution program.

(6) Steven J. Malcolm and Jim W. Mogg did not stand for re-election at our 2024 annual meeting of shareholders. As such, their cash compensation reflected is for

board service from January 2024 to April 2024.

COMPENSATION COMMITTEE INTERLOCKS AND

INSIDER PARTICIPATION

At times during 2024, Messrs. Larson, Malcolm, Rodriguez, and G. Smith and Mss. Gobillot and Moore served on our Executive Compensation

Committee. No member of the Executive Compensation Committee was an officer or employee of the company or any of its subsidiaries during

2024, was formerly an officer of the company or any of its subsidiaries, or had any relationship requiring disclosure under any paragraph of

Regulation S-K Item 404 transactions. In addition, during 2024, none of our executive officers served as a member of a compensation committee or

board of directors of any other entity of which any member of our Board was an executive officer or whose executive officers served on our Executive

held during the year. We intend to continue this practice of regularly scheduled separate meetings of the independent members of our Board.

Ms. Edwards, our independent Board Chair, presides at such meetings.

ANNUAL BOARD AND

COMMITTEE EVALUATIONS

Board and committee evaluations play a critical role in ensuring the effective functioning of our Board and its committees. It is important to take stock

of Board and committee performance and to solicit and act upon feedback received from each member of our Board. To this end, under the

leadership of our Corporate Governance Committee Chair, the Corporate Governance Committee is responsible for evaluating the performance of

our Board annually. Each of our Board committees also annually conducts a self-evaluation.

40 2025 ONEOK, Inc. Proxy Statement

Governance of the Company

The Board believes that, in addition to serving as a tool to evaluate and improve performance, evaluations can serve several other purposes,

including the promotion of good governance, integrity of financial reporting, reduction of risk, strengthening of the Board-management partnership,

the encouragement of candid and constructive dialogue and helping set and oversee Board expectations of management. In assessing their

performance, the Board and its committees seek to assure themselves that areas identified for improvement are appropriately and timely addressed.

As part of the Board’s evaluation process, directors consider various topics related to Board composition, structure, effectiveness and

responsibilities, and the overall mix of director skills, experience and backgrounds. While the Board and each of its committees conduct evaluations

annually, the Board considers its performance and that of its committees throughout the year and shares feedback with management.

Topics considered during the 2024 annual Board evaluation process included:

• Do we have the proper set of skills, knowledge and experience on the Board that align with our long-term strategy?

• Are directors well versed in good corporate governance?

• Are directors engaged, committed to excellence and functioning at a high level?

• Does the onboarding process effectively equip new directors with the necessary corporate, industry, financial, and strategic knowledge for rapid

Board integration and meaningful contribution?

• Does the Board receive the appropriate level of information in a timely manner?

• Is the Board focused on the right information and topics in order for the company to deliver value to all our shareholders?

• How effectively are the speakers and presentations the Board receives: (i) addressing critical emerging trends and risks, (ii) providing actionable

insights that inform Board decision-making, and (iii) stimulating robust and forward-thinking discussions among Board members?

• Does the Board receive high-quality and appropriate input from its outside advisors?

• Is the Board structure appropriate, and are Board committees functioning at a high level?

• Are director expertise and skills optimally aligned with their committee assignments?

• Is the relationship between the Board and management appropriate, and are management presentations to the Board of a high quality?

• Are the Board meetings and executive sessions conducted in a manner that fulfills the Board’s obligations, encourages discussion, delivers value-

added direction and provides for critical oversight?

COMMUNICATIONS WITH DIRECTORS

Our Board believes that it is management’s role to speak for our company. Our Board also believes that any communications between members of

the Board and interested parties, including shareholders, should be conducted with the knowledge of our chief executive officer. Interested parties,

including shareholders, may contact one or more members of our Board by writing to the director(s) in care of our corporate secretary at our principal

executive offices. A communication received from an interested party or shareholder will be forwarded promptly to the directors to whom the

communication is addressed. A copy of the communication also will be provided to our chief executive officer. We will not, however, forward sales or

marketing materials, materials that are abusive, threatening or otherwise inappropriate, or correspondence not clearly identified as interested party or

shareholder correspondence.

COMPLAINT PROCEDURES

Our Board has adopted procedures for the receipt, retention, treatment, and resolution of complaints regarding accounting, internal accounting

controls, or auditing matters and complaints or concerns under our Code of Business Conduct and Ethics. These procedures allow for the

confidential and anonymous submission by employees and other persons and stakeholders of concerns regarding accounting or auditing matters

and matters arising under our Code of Business Conduct and Ethics. The full text of these procedures, known as our whistleblower policy , is

published on and may be printed from our website at www.oneok.com and is also available from our corporate secretary, free of charge,

ENVIRONMENT, SAFETY AND HEALTH COMMITMENT

Our goal is to operate our assets safely, efficiently and in an environmentally responsible manner. As our business grows, we remain committed to

our ONEOK values and to keeping our focus in the right place—on our employees and our mission to deliver energy products and services vital to an

advancing world.

We are committed to pursuing a zero-incident culture by continuously working toward mitigating risk and avoiding incidents that may

harm our employees, contractors, the public and the environment. To meet corporate and operating ESH expectations, all of our

leadership, employees and contractors must demonstrate a commitment to the following:

The responsibility and ability to control operational exposures that may cause an incident, even if it means stopping work;

Personal involvement and commitment to ESH management and compliance;

The responsibility to report, or elevate to the proper level in the organization, potential ESH compliance risks, incidents and near misses;

Understanding that protection of human health, safety and the environment is a top priority, no matter how urgent the job, project or

commercial interests;

Being responsible and accountable for understanding and complying with all applicable laws, regulations, permits, requirements and procedures

related to their roles and responsibilities, including those associated with ESH; and

The execution and implementation of our sustainability efforts.

Environment

We continue our focus on appropriate environmental sustainability initiatives while operating our assets safely and reliably. We work to

minimize the environmental impact of our services while continuously searching for new ways to meet stakeholder expectations for

environmental stewardship. Our environmental efforts focus on minimizing the impact of our operations on the environment. These

actions include:

Greenhouse Gas Emissions

We are committed to understanding and managing our emissions and seeking ways to improve energy efficiency in our operations. We monitor

emissions, undertake projects to manage operating emissions and apply innovative technologies to improve our energy efficiency. Emissions from

combustion in natural gas compressor engines and process heaters, fugitive emissions from our operating equipment and other processes common

to natural gas and liquids systems, are the primary sources of GHG emissions at our facilities.

As a midstream service provider, we gather, process, fractionate, transport and store hydrocarbon products for many customers. We deliver these

products to the market, and they are eventually delivered to consumers. Emissions from these activities and sources, including fugitive emissions,

compressor engine, heater and reboiler exhaust stacks, pressure relief stacks, dehydrator vents and storage tanks are referred to as Scope 1

emissions. Emissions that are attributable to electricity consumption are referred to as Scope 2 emissions. Reported emissions that result from our

customers’ combustion or oxidation of NGL and hydrocarbon products produced from our fractionation facilities are referred to as Scope 3 emissions.

There are several methodologies for calculating and determining GHG emissions, and we may in certain instances use and/or disclose different

calculations to respond to different stakeholder needs or expectations. However, our primary guidance for calculating our emissions figures at

present is taken from the EPA reporting requirements.

Federal GHG emission regulations require annual reporting of emissions from several source categories. To see annual GHG emissions as reported

to EPA, total Scope 1, Scope 2 and Scope 3 emissions, please review our ONEOK ESG Performance Data Sheet on our website at

www.oneok.com , the contents of which are expressly not incorporated herein by this reference.

Greenhouse Gas Emissions Reduction Target and Update

on Progress

In 2021, we announced a companywide absolute GHG emissions reduction target of 2.2 million metric tons (“MMT”) of carbon dioxide equivalents

from our combined Scope 1 and Scope 2 GHG emissions by 2030 for our legacy ONEOK assets . This target represents a 30% reduction in

combined operational Scope 1 and location-based Scope 2 GHG emissions attributable to legacy ONEOK assets as of December 31, 2019.

2019 base-year levels. NOTE: Scope 1 emissions are defined as emissions that result directly from operations. Scope 2 emissions are defined as indirect

emissions that occur from the consumption of energy generated by other entities, such as a utility.

PROGRESS 77% achieved 77% = 1.7 MMT reduction vs. 2019

0 1.1MMT 2.2MMT

the targeted 2.2 MMT of carbon dioxide equivalents, primarily as a result of methane emissions

mitigation, system utilization and optimizations, electrification of certain natural gas compression

equipment and lower carbon-based electricity in states in which we operate. GHG emission

reductions as reported may be modified, updated, changed or supplemented based on available

information. For the years ended December 31, 2024, 2023 and 2022, we did not have any

material dedicated capital expenditures specifically for climate-related projects, nor did we

purchase or sell carbon credits or offsets. Progress to date on our goal has been accomplished

through routine capital projects and asset optimizations that were primarily performed for

operational improvements that inherently improved our emissions profile. We continue to

anticipate several potential pathways toward achieving our emissions reduction target. In 2025,

we intend to work towards further reductions in our emissions toward our target through improved methane management practices and system

optimization that will not require material capital expenditures. We do not anticipate purchasing or selling carbon credits or offsets in 2025.

We currently participate in Our Nation’s Energy (ONE) Future Coalition to voluntarily report methane emission reductions and to calculate our

methane intensity for our natural gas transmission and storage assets. We continue to focus on maintaining low methane gas release rates through

expanded implementation of improved practices to limit the release of natural gas during pipeline and facility maintenance and operations.

We are a participant in American Petroleum Institute’s The Environmental Partnership and are enrolled in environmental performance programs that

are designed to further reduce emissions using proven, cost-effective controls.

In 2024, additional efforts related to emissions reductions included :

Expanding our natural gas gathering and processing (“NGGP”) and NGL infrastructure in the Williston Basin, which led to a significant reduction

of third-party gas flaring by our customers;

Using vapor-recovery units and combustors to capture or combust natural gas that otherwise would be vented;

Installing compression-optimization tools on certain transmission pipelines, which has decreased emissions;

Replacing or removing high-bleed natural gas-driven pneumatic devices with low-bleed or zero-bleed devices;

Using “hot taps” when practical, instead of venting/flaring of pipeline segments when making connections;

Reducing pressures on compressors and pipelines prior to venting to conserve natural gas and reduce emissions when taking assets offline for

maintenance or other reasons; and

Implementing rigorous and regular leak-inspection programs.

ESG Performance Disclosures

Our Board and executive leadership team evaluate climate-related risks and opportunities in connection with corporate strategic planning, including

discussions related to reducing emissions, energy transition, and transformation.

ONEOK’s Board is involved in our company’s annual comprehensive ERM process that encompasses the identification and assessment of a broad

range of risks and the development of plans to mitigate these risks. Such risks generally relate to strategic, operational, financial, regulatory

compliance, climate-related considerations, ESG, cybersecurity and human capital management aspects of our business.

To help guide ONEOK’s ESG performance disclosures, the company references several recognized third-party reporting standards and frameworks

and monitors dialogue regarding regulations addressing such disclosures.

For more information about ONEOK’s ESG Performance Data and the location of current disclosures that align with SASB, GRI and TCFD voluntary

reporting standards and frameworks, please review pages 94-114 of our 2023-2024 Corporate Sustainability Report, on our website

ESG Highlights and Awards

Highlights and awards include the following, each of which was earned during 2024:

• Maintained an MSCI ESG Rating of AAA.

• Received an ESG Risk Rating in the top 20% of the refiners and pipelines industry, as assessed by Morningstar Sustainalytics.

• Qualified for inclusion in the FTSE4Good Index Series.

• Achieved combined company best (lowest) Agency Recordable Environmental Event Rate ("AREER").

Short-Term Incentive Environmental Metric

We established an internal environmental performance metric in 2014 that became a part of the short-term incentive compensation plan performance

criteria for all our employees. Our AREER is defined as the total number of releases and excess emission events that trigger a federal, state or local

environmental reporting requirement (with some exceptions to account for events outside our control, planned maintenance and disparities in

reporting requirements across our operations) per 200,000 work-hours. This metric promotes a continued reduction in spills and emission events that

are reportable to a federal, state or local agency. Since the implementation of the AREER metric in 2014, we have seen substantial reductions

overall in our rate of reportable environmental events. In 2024, we set an AREER target of 0.74, which was established after taking into account the

Magellan acquisition, and achieved a result of 0.33 , which was 55% below the target goal (representing above target performance).

HUMAN CAPITAL MANAGEMENT

The long-term sustainability of our business is dependent on our continued ability to maintain a highly engaged workforce. To accomplish this, our

business strategy includes attracting, selecting and retaining talent, advancing an inclusive, diverse and engaged culture and developing individuals

and leaders.

We conduct employee engagement surveys, typically on an annual basis. In 2024, the annual employee engagement participation rate increased to

93% compared with 90% in 2022, the last year a survey was conducted. We did not complete a survey in 2023 as we focused on stabilizing and

integrating our employee base following the Magellan acquisition. The overall engagement mean increased to the 80th percentile and the ratio of

engaged employees to actively disengaged also increased. All leaders have been asked to discuss the 2024 survey results with their teams and

create an engagement plan for 2025. Training and support resources are available through our learning management system, the Gallup

engagement portal and dedicated individuals, engagement champions within the business.

Human Capital Management Oversight

Our Board provides key leadership, guidance and diverse energy industry and business expertise as it oversees executive management’s

development and implementation of the company’s human capital management practices.

Our CEO, executive management and others engage with the Board on the company’s human capital management practices. Communication and

engagement include attendance and participation at Board and committee meetings, along with regular informational updates. Our Board also

conducts a biannual examination of the company’s human capital management practices, performance, risks and opportunities for Board and

committee oversight purposes.

Human Capital Resources, Measures and Objectives

As of December 31, 2024, we had 5,177 employees, which excludes EnLink employees. Listed below is a summary of our human capital resources,

measures and objectives that are collectively important to our success as an organization.

Values - Our success relies on the skills, experience and dedication of our employees. We are committed to cultivating an inclusive and dynamic

work environment where people can find opportunities to succeed, grow and contribute to the success of the company. Our employees work each

day to provide safe and reliable services to a wide range of customers in the states where we operate. Our core values, listed below, guide our

employee behaviors and the ways in which we conduct our business and operations.

• Safety & Environmental: We commit to a zero-incident culture for the well-being of our employees, contractors and communities and to operate

in an environmentally responsible manner.

• Ethics: We act with honesty, integrity and adherence to the highest standards of personal and professional conduct.

• Inclusion and Diversity: We respect the uniqueness and worth of each individual, and we believe that an inclusive culture and diverse workforce

are essential for a sense of belonging, engagement and performance.

• Excellence: We hold ourselves and others accountable to a standard of excellence through continuous improvement and teamwork.

• Service: We invest our time, effort and resources to serve each other, our customers and communities.

• Innovation: We seek to develop creative solutions by leveraging collaboration through ingenuity and technology.

Inclusion and Diversity - Our inclusion and diversity ("I&D") strategy is a cross-functional effort that draws upon contributions from employees at all

levels of the organization and is focused on enhancing the workplace to attract and retain talent. The strategy is guided by a council composed of a

diverse group of employees who represent different demographics, work locations, points of view, roles and levels of seniority. We also have a team

within our human resources department that is wholly dedicated to supporting our I&D efforts.

We provide support for four employee-led business resource groups ("BRGs") that include a Racial/Ethnic Inclusion Resource Group, Veterans

Resource Group, Women’s Resource Group and LGBTQ+ Resource Group. The purpose of these groups is to promote the attraction, development,

engagement and retention of members of traditionally underrepresented groups in our industry and workplace in an effort to drive positive business

outcomes. A key factor in the success of our BRGs is the active participation by officer-level executive sponsors and allies from outside the BRG’s

underrepresented populations. All employees are invited to become supporters of our BRGs.

2025 ONEOK, Inc. Proxy Statement 49

Corporate Sustainability

We embed I&D concepts into our core leadership development curriculum and sponsor a number of internal programs intended to promote I&D. In

addition, we seek to give back to the communities where we operate by partnering on initiatives to support underrepresented community members

and local charitable organizations.

Employee Safety - The safety of our employees is critical to our operations and success. By promoting the safety of our employees and monitoring

the integrity of our assets, we are investing in the long-term sustainability of our businesses. We continuously assess the risks our employees face in

their jobs, and we work to mitigate those risks through training, appropriate engineering controls, work procedures and other preventive safety

programs. Reducing incidents and improving our personal safety incident rates are important, but we are not focused only on statistics. Low personal

safety incident rates alone cannot prevent a large-scale incident, which is why we continue to focus on enhancing our ESH management systems

and process safety programs, such as key risk/key control identification and knowledge sharing. We endeavor to operate our assets safely, reliably

and in an environmentally responsible manner. We maintain mature and robust programs that guide trained staff in the completion of these activities,

and we continue to enhance and improve these programs and our internal capabilities.

Health and Welfare - We provide a variety of benefits to help promote the health and welfare of our employees and their families. These benefits

include medical, dental and vision plans, virtual health visits and engagement of third-party service providers to offer company on-site and near-site

clinics in several of our operating areas. Eligible employees also have access, at no charge, to an employee assistance program, a medical second

opinion service and a health care concierge service to assist with finding in-network providers and billing resolution. We offer full pay for maternity,

paternity or adoption leave of up to 240 hours per qualifying event. We also provide up to $10,000 for reasonable and necessary expenses of a

qualifying adoption and/or surrogacy. Additional benefits available for the welfare of our employees include, among others, life insurance and long-

term disability plans, health and dependent care flexible spending accounts, fertility benefits, disease prevention and management programs and full

pay while on bereavement, military or personal and family care leave. We expect that beginning on May 1, 2025, legacy EnLink employees will have

access to these ONEOK health and welfare benefits.

We also provide the opportunity for our employees to help fellow employees through the ONE Trust Fund by contributing donated vacation hours or

monetary donations. The ONE Trust Fund is a nonprofit, charitable organization run entirely by employee volunteers, that serves our employees in

times of personal crises due to natural disasters, medical emergencies or other hardships. Further, we provide volunteer opportunities and volunteer

grants, as well as $10,000 of charitable giving matching, annually, through the ONEOK Foundation. Subsequent to the EnLink acquisition completed

on January 31, 2025, we expect legacy EnLink employees to have access to the ONE Trust Fund benefits and can begin making contributions to the

fund beginning on May 1, 2025.

Personal and Professional Development - We provide various options to assist with career growth and development. For employees just entering

the workforce who desire to advance their career and continue to learn or for the employees who are interested in developing their skills, we provide

education and training in a variety of areas, including leadership, functional and industry-specific topics, professional development and skill-building

opportunities. Our organizational development and I&D teams provide live in-person and virtual classroom training, computer-based self-study and

one-on-one coaching that is available to all employees.

We value education and assist eligible employees with the expense of furthering their education in job-related fields, including up to $5,250 per year

in qualifying tuition expenses. We also may reimburse employees for certain job-related professional certification examination fees.

Recruiting - We make it a priority to attract, select, develop, motivate, challenge and retain the talent necessary to support our key business

strategies. We use targeted recruitment events, maintain strong relationships with area technical schools, colleges and universities, and we offer

compensation benefits and career opportunities that are designed to position us as an employer of choice. I&D continues to be a priority in recruiting,

and we deploy sourcing strategies designed to access talent from groups that are historically underrepresented in our industry and workplace.

Retirement - We maintain a 401(k) Plan for our employees and match 100% of employee contributions up to 6% of eligible compensation each

payroll period, subject to applicable tax limits. We have a legacy defined benefit pension plan covering certain employees and former employees,

which closed to new participants in 2005. In addition, as a result of the Magellan acquisition , we assumed the pension and postretirement benefit

obligations for Magellan employees and former employees. These obligations are composed of two defined benefit pension plans, including one for

non-union employees and one for union employees, as well as a postretirement welfare benefit plan for certain employees. The pension plan for non-

union employees closed to new participants upon the closing of the Magellan acquisition. The pension plan for union employees closed to new

participants in January 2024. Employees who do not participate in our defined benefit pension plans are eligible to receive quarterly and annual

profit-sharing contributions under our 401(k) Plan. Effective January 1, 2025, the profit-sharing quarterly contributions increased to 6% from 1% of

quarterly eligible compensation. We will continue to make annual discretionary contributions of up to 2% of eligible compensation. As of December

31, 2024, 96% of eligible employees were contributing to our 401(k) Plan. For additional information about our retirement benefits, see Note M of the

Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2024.

COMMUNITY INVESTMENTS

We value being a good corporate citizen and are committed to fostering partnerships among our company, our employees and the communities in

which we operate. We seek to give back through building partnerships with community organizations and key stakeholders that address local needs

and provide resources for all to benefit. Providing community investments, programs and opportunities that encourage and support engagement

create shared value by connecting the success of our business with societal progress.

We strategically invest in charitable organizations and causes that align with our company’s values, as well as meet community needs by providing

valuable services and resources. Through financial contributions and volunteer service, our goal is to enhance the quality of life and economic

well-being of our communities while creating a positive environment in which to do business. The ONEOK Foundation enables a consistent level of

giving through grants and pledges to non-profit organizations, and ONEOK provides corporate contributions, generally in the form of sponsorships, in

support of charitable organizations and events.

We encourage employees to volunteer for company-sponsored projects or serve, using personal time, on charitable or civic boards and

organizations. Our Employee/Director/Retiree Matching Grant program and volunteer service grants further support those efforts.

2024 Community Investments Highlights

• The ONEOK Foundation contributed approximately $3.7 million, and ONEOK made corporate contributions of approximately $5.0 million to

support local charitable organizations.

• Approximately 350 communities were impacted by one or more of our community investments programs.

• Total volunteerism (employees/family/friends/retirees): 1,375 volunteers; 19,615 hours.

• Estimated value of total company volunteerism: $656,906 (Based on the estimated value per hour of volunteer time of $33.49).

POLITICAL ADVOCACY AND OVERSIGHT

Oversight of our lobbying and political activities is conducted by our Board and our Corporate Governance Committee. We believe this oversight

process facilitates accountability and transparency concerning our lobbying and political activities.

As a company, we generally do not make corporate contributions to political candidates, parties, committees or campaigns, or to 501(c)(4)

organizations formed for political purposes. We have made such contributions in the past, but they were very infrequent and for immaterial amounts.

We have no intention of making such contributions in the future , and any decision to do so would be subject to review by the Corporate Governance

Committee of the Board. In addition, in most circumstances, we will not make contributions designed to influence the outcome of ballot measures.

However, we have in the past, and may in the future, support or oppose specific ballot measures that could impact our company or its employees,

assets or operations. In the event we decide to support or oppose a particular ballot measure, we will provide the appropriate disclosure of such

support or opposition, including any corporate funds expended for that purpose.

We do, however, actively participate in the political process through the lobbying efforts of our government relations department and involvement in

multiple business and industry trade organizations.

Our government relations team works with state and federal legislators to ensure ONEOK’s inclusion in the discussion of key legislative issues that

affect the company’s ability to operate. We also work with state and federal regulatory authorities on issues that arise by way of company filings with

those authorities. In 2024, we monitored legislation on a variety of issues that could impact our businesses, including natural gas flaring, pipeline

safety, local control, eminent domain, permitting reform, infrastructure and operational security and disaster-response efficiency, state and federal tax

issues and reclamation and restoration of pipeline rights of way. During 2024, we also paid $394,150 for state a nd federal lobbying activities. We

belong to several industry associations that participate in the political process. These associations promote collaboration between companies within

an industry concerning public policy initiatives and represent industry interests in the legislative and regulatory arenas. Our primary purpose in

becoming a member of these industry associations is not for political purposes, as we may not agree with all positions taken by industry associations

on issues. The benefits that we receive from industry associations are primarily expertise and the ability to gain insight on industry related matters. In

2024, we paid dues of $1,906,253 to 58 trade and industry-related associations, of which 11% was allocated by those associations to lobbying

expenses and political expenditures.

ONEOK, Inc. Political Action Committee

Political contributions to federal, state and local candidates are made by the ONEOK, Inc. Political Action Committee (“ONEOK PAC”), which is

entirely funded by voluntary contributions from eligible company employees. The ONEOK PAC’s activities are guided by a steering committee

composed of members of senior management and a contribution committee composed of ONEOK PAC members and are subject to comprehensive

regulation, including detailed disclosure requirements. ONEOK PAC contributions are reported to the Federal Election Commission and applicable

state regulatory authorities. During 2024, the ONEOK PAC made contributions to state and federal candidates totaling $156,945 .

ONEOK routinely engages with our shareholders and others to better understand their views on ESG matters, carefully considering the feedback we receive and acting when appropriate.

Ratify the Selection of PricewaterhouseCoopers LLP as Our Independent Registered Public Accounting Firm for the Year Ending December 31, 2025
●	Our Board unanimously recommends a vote FOR the ratification of the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2025.

Ratification of Selection of PricewaterhouseCoopers LLP as

Our Independent Registered Public Accounting Firm For 2025

The Audit Committee has the sole authority and responsibility to evaluate, hire and, where appropriate, replace the company’s independent auditor

and, in its capacity as a committee of the Board, is directly responsible for the appointment, compensation and general oversight of the work of the

independent auditor. The Audit Committee is also responsible for approving the audit and permissible non-audit services provided by the

independent auditor and the associated fees.

The Audit Committee evaluates the performance of our independent auditor, including the senior audit engagement team, each year and determines

whether to re-engage the current independent auditor or consider other audit firms. In doing so, the Audit Committee considers the quality and

efficiency of the services provided by the auditors, the auditors’ capabilities, technical expertise and knowledge of our operations and industry and

the potential impact on the company from changing auditors. In connection with the mandated rotation of the independent auditor’s lead engagement

partner, the Audit Committee and its Chair are directly involved in the selection of the new lead engagement partner.

Based on this evaluation, the Audit Committee appointed PricewaterhouseCoopers LLP to serve as our independent auditor for the fiscal year

ending December 31, 2025. PricewaterhouseCoopers LLP has served as our independent auditor for 18 years and is considered by management to

be well qualified. Further, the Audit Committee and the Board believe that the continued retention of PricewaterhouseCoopers LLP to serve as our

independent auditor is in the best interests of the company and its shareholders.

The Board has ratified the selection by our Audit Committee of PricewaterhouseCoopers LLP to serve as our independent (consistent with Securities

and Exchange Commission and NYSE policies regarding independence) registered public accounting firm for 2025. As a matter of good corporate

governance, the Audit Committee submits its selection of our independent auditor to our shareholders for ratification. If the shareholders should not

ratify the appointment of PricewaterhouseCoopers LLP, the Audit Committee will reconsider the appointment. In carrying out its duties in connection

with the 2024 audit, PricewaterhouseCoopers LLP had unrestricted access to our Audit Committee to discuss audit findings and other financial

matters. Representatives of PricewaterhouseCoopers LLP will be present at the annual meeting to answer appropriate questions. They also will have

the opportunity to make a statement if they desire to do so.

Approval of this proposal to ratify the selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm requires the

affirmative vote of a majority of the voting power of the shareholders present online or by proxy and entitled to vote on the proposal at the meeting.

Abstentions will have the effect of a vote against the proposal.

Audit Committee Policy on Services Provided by the

Independent Registered Public Accounting Firm

Consistent with Securities and Exchange Commission and NYSE policies regarding auditor independence, the Audit Committee has the

responsibility for appointing, setting compensation and overseeing the work of our independent auditor. In furtherance of this responsibility, the Audit

Committee has established a policy with respect to the pre-approval of audit and permissible non-audit services provided by our independent auditor.

All of the 2024 and 2023 audit and non-audit services provided by PricewaterhouseCoopers LLP were pre-approved by the Audit Committee in

accordance with this policy.

Prior to the engagement of PricewaterhouseCoopers LLP as our independent auditor for the 2025 audit, a plan was submitted to and approved by

the Audit Committee setting forth the audit services expected to be rendered during 2025. This scope of work to be performed in the audit of our

financial statements and in attesting and reporting on our internal control over financial reporting, as well as work that only the independent auditor

can reasonably be expected to provide, including quarterly review of our unaudited financial statements, comfort letters, statutory audits, attestation

services, consents and assistance with the review of documents filed with the Securities and Exchange Commission.

The Audit Committee has adopted a policy that provides that fees for audit, audit related and tax services that are not included in the independent

auditor’s annual services plan, and for services for which fees are not determinable on an annual basis, are pre-approved if the fees for such

services will not exceed $75,000 . In addition, the policy provides that the Audit Committee may delegate pre-approval authority to one or more of its

members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit

Committee at its next scheduled meeting.

PROPOSAL 2: Ratify the Selection of PricewaterhouseCoopers LLP

2025 Report of the Audit Committee

The purpose of the Audit Committee is to assist the Board with the oversight of the integrity of the company’s financial statements and internal

control over financial reporting, the company’s compliance with legal and regulatory requirements, the independence, qualifications and performance

of the company’s independent auditor and the performance of the company’s internal audit function. The Audit Committee’s function is more fully

described in its charter, which the Board reviews and approves on an annual basis. The charter is published on and may be printed from the

company’s website at www.oneok.com and is also available from the company’s corporate secretary upon request. The Board annually reviews the

definition of “independence” for audit committee members contained in the listing standards for the NYSE and applicable rules of the Securities and

Exchange Commission, as well as our Director Independence Guidelines, and has determined that each member of the Audit Committee is

independent under those standards.

Management is responsible for the preparation, presentation and integrity of the company’s financial statements, accounting and financial reporting

principles, internal controls and procedures designed to ensure compliance with accounting standards, applicable laws and regulations. The

company’s independent auditor, PricewaterhouseCoopers LLP, is responsible for performing an independent audit of the company’s consolidated

financial statements and the company’s internal control over financial reporting and expressing an opinion on the conformity of those financial

statements with generally accepted accounting principles and on the effectiveness of the company’s internal control over financial reporting.

In this context, the Audit Committee has met and held discussions with management and the company’s independent auditor,

PricewaterhouseCoopers LLP, regarding the fair and complete presentation of the company’s financial results and management’s report on its

assessment of the company’s internal control over financial reporting. The Audit Committee has discussed the significant accounting policies applied

by the company in its financial statements, as well as alternative treatments. Management has represented to the Audit Committee that the

company’s consolidated financial statements were prepared in accordance with generally accepted accounting principles, and the Audit Committee

has reviewed and discussed the consolidated financial statements with management and the company’s independent auditor.

The Audit Committee has also reviewed and discussed with both management and the independent auditor management’s assessment of the

company’s internal control over financial reporting. In addition, the Audit Committee has discussed the independent auditor’s report on the company’s

internal control over financial reporting. The Audit Committee has also discussed with the company’s independent auditor the matters required to be

discussed by the applicable requirements of the Public Company Accounting Oversight Board and the Securities and Exchange Commission.

In addition, the Audit Committee has discussed with the independent auditor the firm’s independence from the company and its management,

including the matters in the written disclosures and the letter received from PricewaterhouseCoopers LLP as required by the applicable requirements

of the Public Company Accounting Oversight Board (United States) regarding the independent auditor’s communications with the Audit Committee

concerning independence. While non-audit services provided by PricewaterhouseCoopers LLP did not impact the Audit Committee’s determination of

PricewaterhouseCoopers LLP’s independence in 2023 or 2024, the Audit Committee will consider in the future whether the provision of non-audit

services to the company by PricewaterhouseCoopers LLP is compatible with maintaining that firm’s independence. The Audit Committee has

concluded that PricewaterhouseCoopers LLP is independent from the company and its management.

The Audit Committee discussed with the company’s internal and independent auditors the overall scope and plans for their respective audits.

The Audit Committee meets with both the internal and independent auditors, with and without management present, to discuss the results of their

examinations, the assessments of the company’s internal control over financial reporting and the overall quality of the company’s financial reporting.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board, and the Board approved, the inclusion of

the audited financial statements of the company as of and for the year ended December 31, 2024, in the company’s Annual Report on Form 10-K for

the year ended December 31, 2024, for filing with the Securities and Exchange Commission.

Respectfully submitted by the members of the Audit Committee of the Board.

voting or investment power , shares of common stock held in our Direct Stock Purchase and Dividend Reinvestment Plan, and shares held through our 401(k) Plan.

(2) Represents shares of phantom stock credited to a director’s account under our Deferred Compensation Plan for Non-Employee Directors. Each share of phantom

stock is equal to one share of our common stock. Phantom stock has no voting or other shareholder rights, except that dividend equivalents are paid on phantom

stock and reinvested in additional shares of phantom stock based on the closing price of our common stock on the NYSE on the date the dividend equivalent was

paid. Shares of phantom stock do not give the holder beneficial ownership of any shares of our common stock because they do not give such holder the power to

vote or dispose of any shares of our common stock.

(3) The percent of our voting securities owned is based on our shares of common stock outstanding on March 1, 2025.

(4) Excludes 2,770, 11,412 and 5,416 shares, the receipt of which was deferred by Mr. Swords upon vesting in January 2010, January 2011 and February 2017,

respectively, under the deferral provisions of our Equity Compensation Plan, which shares will be issued to Mr. Swords upon his separation of service from our

company and in accordance with the terms of the Equity Compensation Plan.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires our directors, executive officers and beneficial owners of 10% or more of our common stock to file with

the Securities and Exchange Commission initial reports of ownership and reports of changes in ownership of our common stock. Based solely on a

review of the copies of reports furnished to us and representations that no other reports were required, we believe that all of our directors, executive

officers, and holders of 10% or more of our outstanding shares during the fiscal year ended December 31, 2024, complied on a timely basis with all

applicable filing requirements under Section 16(a) of the Exchange Act, except that one Form 4 filing reporting the vesting of performance and

restricted units made on behalf of each of Kevin L. Burdick, Walter S. Hulse, III, Charles M. Kelley, Pierce H. Norton II, Mary M. Spears, and

Sheridan C. Swords, was filed two business days late due to an unintentional administrative error.

EXECUTIVE COMPENSATION DISCUSSION AND ANALYSIS

EXECUTIVE SUMMARY

Our Executive Compensation Discussion and Analysis (“CD&A”) focuses on our 2024 compensation programs and decisions relative to our 2024

performance. The 2024 short-term incentive payouts described in this CD&A were based on consideration of our financial, safety and environmental

performance in 2024, and the payouts upon the vesting of performance units reflects our total shareholder return relative to our peer group through

February 2024. As described further in this CD&A, our executive compensation program is designed to strongly align realizable compensation with

performance. Therefore, the value of executives’ stock awards is aligned with, and impacted by, changes in our stock price.

Our Business

We are incorporated under the laws of the state of Oklahoma, and our common stock is listed on the NYSE under the trading symbol “OKE.” We

deliver energy products and services vital to an advancing world. We are a leading midstream service provider of gathering, processing,

fractionation, transportation, storage and marine export services. As one of the largest diversified energy infrastructure companies in North America,

we are delivering energy that makes a difference in the lives of people in the U.S. and around the world. Through our now approximately 60,000-mile

pipeline network, we transport the natural gas, NGLs, refined products and crude oil that help meet domestic and international energy demand,

contribute to energy security and provide safe, reliable and responsible energy solutions needed today and into the future .

Our Growth Journey

Since September 2023, ONEOK has embarked on a transformative journey of growth, closing a series of acquisitions that have strengthened our

position as an energy industry leader by adding new growth platforms in crude oil and refined products to our stable and reliable natural gas and

NGLs businesses.

The successful acquisition of Magellan in September 2023 diversified the company’s assets, adding a refined products and crude business to

ONEOK’s portfolio. Building on this momentum, ONEOK further bolstered its portfolio in 2024-2025 with acquisitions of a Gulf Coast NGL pipeline

system from Easton Energy and the acquisitions of Medallion and EnLink.

These acquisitions expanded and extended our integrated position in some of the most prolific basins in the U.S. – including the Permian Basin –

with connectivity to critical energy demand hubs across the country like the Texas and Louisiana Gulf Coast.

• Business Update and Market Conditions: We operate primarily fee-based businesses in each of our four reportable segments (Natural Gas

Gathering and Processing; Refined Products and Crude; Natural Gas Liquids; and Natural Gas Pipelines), and our consolidated earnings were

approximately 90% fee-based in 2024.

Over the past year, we experienced significant growth across our value chain due to our recent acquisitions. Earnings increased in 2024,

compared with 2023, due primarily to a full year of earnings from the new Refined Products and Crude segment, higher NGL and natural gas

processing volumes in the Rocky Mountain region and the impact of the interstate pipeline system divestiture in the Natural Gas Pipelines

segment. Our extensive and integrated assets are located in, and connected with, some of the most productive shale basins, as well as refineries

and demand centers, in the United States.

• Financial Performance: Our 2024 consolidated operating income was approximately $5.0 billi on, compared with approximately $4.1 billion in

2024 net income was approximately $3.1 billion compared with 2023 net income of approximately $2.7 billion.

• Dividends: During 2024, we paid common stock dividends totaling $3.96 per share, an increase of 3.7% compared with the prior year. In

February 2025, we paid a quarterly common stock dividend of $1.03 per share ($4.12 per share on an annualized basis), an increase of 4%

compared with the same quarter in the prior year. Our dividend growth is primarily due to the increase in cash flows resulting from the growth of

our operations.

Executive Compensation Discussion and Analysis

2024 Executive Compensation Highlights

During 2024, management strengthened the company’s position while navigating the increasing complexities of the energy industry. We believe a

meaningful portion of this success is related to our incentive compensation program, which is designed to pay-for-performance and to closely align

our executives’ interests with those of our shareholders. Our named executive officers for 2024 were Pierce H. Norton II, Walter S. Hulse, III,

Kevin L. Burdick, Sheridan C. Swords and Lyndon C. Taylor (referred to throughout as our “named executive officers”). Mr. Taylor joined the

company in October 2023.

The Committee’s primary recommendations to our Board, which the Board subsequently approved in February 2024, regarding 2024 compensation

of our named executive officers are summarized below. These actions are consistent with our compensation philosophy described on pages 76 - 77 :

• Increasing Mr. Norton’s base salary by $90,000 ( 10.8% ), short-term incentive target by 25 percentage points, and his long-term incentive target

by $3,000,000 ( 60.00% ) .

• Increasing Mr. Hulse’s base salary by $50,000 ( 8.3% ), short-ter m incentive target by 10 percentage points, and his long-term incentive target by

$1,050,000 ( 47.7% ) .

• I ncreasing Mr. Burdick’s base salary by $50,000 ( 10.0% ) and his long-term incentive target by $200,000 ( 12.5% ) .

• I ncreasing Mr. Swords' base salary by $25,000 ( 5.0% ), short-term incentive target by 10 percentage points, and his long-term incentive target by

$549,999 ( 44.0% ) .

• Inc reasing Mr. Taylor's base salary by $50,000 ( 9.1% ), short-term incentive target by 5 percentage points, and his long-term incentive target by

$1,350,000 ( 270.0% ). Mr. Taylor's long-term incentive target increase for fiscal year 2024 is primarily attributable to the timing of his hire date

occurring in October 2023. As Mr. Taylor joined the Company late in the fiscal year, his initial long-term incentive target reflected his partial-year

service. The subsequent long-term incentive target in February 2024 represents the full annual target consistent with the Company's typical

annual grant cycle for executive officers.

Additional information as to these actions is provided in the 2024 Compensation Decisions section on pages 83 - 84 .

• Maintaining two financial metrics - earnings per share (“EPS”) and return on invested capital (“ROIC”) - and two operational metrics - total

recordable incident rate (“TRIR”) and agency reportable environmental event rate (“AREER”) - under our annual short-term incentive plan

for 2024. For an explanation of these metrics, see “Executive Compensation Discussion and Analysis—2024 Short-Term Incentive

Awards—Financial Measures and Operational Measures” on page 84 .

• Approving long-term equity incentive grants to our named executive officers consisting of approximately 80% of the award’s aggregate value in

performance units and approximately 20% of the award’s aggregate value in restricted units. This is the same allocation of long-term equity

incentive grants to executives in prior years.

• Certifying, based on our total shareholder return performance relative to our peers, a 88% of target payout to our named executive officers with

respect to performance units granted in 2021 that vested in February 2024. This level of payout resulted because our relative total shareholder

return was at the 44th percentile of the total shareholder return of the specified peer group of energy companies.

The Committee’s other recommendations to our Board, which the Board subsequently approved in February 2025, relating to our 2024 short-term

incentive plan are summarized below.

• Ratifying the company’s level of achievement with respect to the financial and operating goals under our 2024 short-term incentive plan resulting

in a corporate performance payout factor of 183.5% of target for our named executive officers and all other employees.

• Assigning an individual performance modifier of 110% to Mr. Norton under our 2024 short-term incentive plan in recognition of his strong

performance and leadership during the year.

• Assigning individual performance modifiers to our other named executive officers as follows under our 2024 short-term incentive plan in

recognition of each individual’s performance and contribution during the year:

Mr. Hulse , 125% Mr. Burdick , 120% Mr. Swords , 115% Mr. Taylor , 125%

(For more information on the executive compensation highlights above, see pages 13 - 14 ).

Executive Compensation Discussion and Analysis

Specific Compensation Program Features

Our compensation philosophy and related governance features are complemented by several specific elements that are designed to align our

executive compensation with long-term shareholder interests.

• The components of our executive compensation program have remained substantially the same for several years. We believe our program is

designed effectively, well aligned with the interests of our shareholders, strongly performance-based and key to achieving our business goals.

• The main objectives of our executive compensation program are to pay-for-performance, to align our executive officers’ interests with those of our

shareholders and to attract, retain, and engage qualified executives.

• All compensation decisions regarding our named executive officers are initially made by the Committee and are then submitted to the Board

for approval.

• The Committee is composed solely of persons who qualify as independent directors under the listing standards of the NYSE.

• We provide the following elements of compensation for our executive officers, including the named executive officers: base salary, an annual

short-term cash incentive award and long-term equity incentive awards.

• The Committee references the median level of the market when determining all elements of compensation, including when considering the

possibility of above or below-target short-term incentive and long-term incentive payments for executive and company performance that exceeds

or is below expectations.

• We implement our pay-for-performance philosophy with a short-term incentive program providing for cash payments based on achievement of

financial and operational goals established annually by the Committee and long-term, performance-based equity incentive awards providing for

vesting levels based on our total shareholder return over a three-year performance period as compared to the total shareholder return of a

specified peer group of energy companies for the same period.

• We encourage alignment of our named executive officers’ interests with those of our shareholders through the award of long-term incentive equity

grants, of which approximately 80% are performance units and approximately 20% are time-vesting restricted units.

• Our executive officers, including the named executive officers, receive no significant recurring perquisites or other personal benefits.

• We have market competitive stock ownership guidelines for our executive officers, including the named executive officers, and members of

our Board.

• We have adopted a clawback policy in compliance with Exchange Act Rule 10D-1 and the corresponding NYSE listing standards. Our clawback

policy permits the recovery of incentive-based cash and any equity compensation in the event of fraud, negligence or intentional misconduct that

directly or indirectly results in a material restatement of all or a portion of our financial statements.

• Our Board has adopted a Securities/Insider Trading Policy prohibiting officers, members of our Board and certain employees designated as

insiders under the policy from engaging in short sales, derivative or speculative transactions in our securities, or purchasing or using, directly or

indirectly through family members or other persons or entities, financial instruments (including puts or calls, prepaid variable forward contracts,

equity swaps, collars and exchange funds) that are designed to hedge or offset any decrease in the market value of our securities. This policy

further provides that employees, including our officers and directors, may not purchase or sell our stock when they are in possession of material

non-public information and that officers, directors and employees in certain designated work groups may trade in our securities only during "open

window" periods (beginning on the third business day after our public release of quarterly or annual earnings and continuing until the first day of

the following calendar quarter) and must pre-clear all purchases and sales of our securities. Further, the policy provides that the company will not

engage in any transactions involving our securities while it is aware of material non-public information relating to the company or our securities .

For the purposes of this policy, “our securities” refers to the common stock, preferred stock and debt issued by us or our respective divisions and

subsidiaries, securities of other companies with a significant relationship to us, as well as derivative securities that relate to or derive their value

from our common stock, debt or such other companies’ stock . The foregoing summary does not purport to be complete and is qualified in its

entirety by reference to the full text of our Securities/Insider Trading Policy, a copy of which is filed as Exhibit 19.1 to our Annual Report on Form

10-K for the fiscal year ended December 31, 2024.

• Our Securities/Insider Trading Policy also prohibits officers and directors from holding our securities in a margin account or pledging our securities

as collateral for a loan. An exception to this prohibition may be granted by the chief executive officer if an officer or director wishes to pledge

shares of our stock as collateral for a loan (but not including a margin account), the officer or director clearly demonstrates the financial capacity

to repay the loan without resorting to the pledged securities, and the terms of the loan prohibit the sale of any of our stock held as collateral when

the officer or director is not permitted to trade in our stock. We are not aware of any officer or member of our Board who has pledged any of his or

her shares of our common stock.

Executive Compensation Discussion and Analysis

• We do not grant awards of stock options or similar option-like rights or instruments and, accordingly, do not have any policy or practice in place

on the timing of awards of options or similar option-like rights or instruments in relation to the disclosure of material non-public information. If, in

the future we anticipate granting awards of stock options or similar option-like rights or instruments, we may establish a policy regarding how the

Board or Committee determines when to grant such awards and how it will take into account material non-public information when determining

the timing and terms of such awards.

• The Committee engages a compensation consultant that the Committee has determined to be independent under the Securities and Exchange

Commission rules and NYSE listing standards to provide advice and expertise on the design and implementation of our executive and director

compensation programs.

The Committee monitors executive compensation trends and developments regarding prevailing types and levels of compensation so we can remain

competitively positioned to attract and retain the executive talent necessary to achieve our strategic, financial and operational goals.

Specific Corporate Governance Features Related

to Compensation

We seek to maintain good governance standards, including standards applicable to the oversight of our executive compensation policies and

practices. The following policies and practices were in effect during 2024:

• The Committee is composed solely of independent directors.

• The Committee’s independent compensation consultant, Meridian Compensation Partners, is retained directly by the Committee and performs no

other services for the company.

• The Committee regularly meets in executive session without management as well as with and without the representatives of Meridian

Compensation Partners.

• The Committee conducts an annual review of our compensation program designed to ensure that the risks arising from the program are not

reasonably likely to have a material adverse effect on our company.

EXECUTIVE COMPENSATION PHILOSOPHY

Our executive compensation philosophy is to pay-for-performance and provide a competitive compensation package to attract, retain, and engage

qualified executives while structuring our executive compensation program in a manner that does not provide incentives for excessive risk-taking.

Pay-for-Performance

We structure our executive compensation program to align the interests of our named executive officers with the interests of our shareholders. We

believe a named executive officer’s compensation should be tied directly to the achievement of our strategic, financial and operating goals, all of

which are designed to deliver value to our shareholders. Therefore, a significant part of each named executive officer’s pay is “at-risk,” in the form of

an annual, short-term, cash incentive award and long-term, equity-based incentive awards. The amount of the annual short-term cash incentive

award earned depends on our company’s performance measured against financial and operating objectives, as well as the named executive officer's

meeting key leadership and development standards. The portion of our named executive officers’ compensation in the form of equity awards ties

their compensation directly to creating shareholder value over the long-term. We believe this combination of annual short-term cash incentive awards

and long-term equity awards aligns the incentives of our named executive officers with the interests of our shareholders.

Competitive Pay

We believe a competitive executive compensation program is an important tool to help us attract, retain, and engage talented executives capable of

leading our company in the competitive business environment in which we operate. We seek to establish total compensation opportunities for our

named executive officers that are within a competitive range of the median of compensation opportunities awarded at our peer companies as further

discussed below. For example, to recognize an individual’s unique qualifications or performance, we may choose to set their total compensation level

above the median. However, if the executive is new to the role, we may set total compensation below the median level. Similarly, exceptional

performance may result in compensation above the median. Earned compensation from these opportunities will vary based on company and

individual performance as well as our stock price performance.

2025 ONEOK, Inc. Proxy Statement 77

Executive Compensation Discussion and Analysis

Our compensation program is designed with the following principles in mind:

• Pay our executives based on their responsibilities, the capabilities and experience they possess, the performance they demonstrate and

market conditions.

• Motivate our executives to conduct our business and manage our assets in a safe and environmentally responsible manner.

Risk Assessment

The Committee believes our compensation program does not provide incentives for excessive risk-taking, and therefore does not produce risks that

are reasonably likely to have a material adverse effect on the company for the following reasons:

• Broad-based Compensation Program: The primary components of our compensation program, including short-term incentive metrics, are the

same for all officers and employees across all of our business units;

• Fixed Pay Component: T he base salary component of compensation is market-based and does not encourage risk-taking because it is a fixed

amount; and

• Prudent Risk Management: Our current short- and long-term incentive plan awards have the following risk-limiting characteristics:

• Under our short-term incentive plan, awards to officers are subject to fixed maximums established by the Committee;

• Awards are reviewed and approved by the Committee considering a variety of indicators of performance (rather than a single indicator of

performance);

• Short- and long-term incentive awards are not tied to formulas that could focus executives on specific short-term outcomes;

• The Committee approves the final short- and long-term incentive plan award payouts after the review and confirmation of individual executive,

operating and financial performance;

• Short-term cash and long-term equity incentive awards are subject to our Compensation Recoupment Policy and other clawback provisions;

• For executive officers, a significant portion of incentive award value is granted in the form of restricted and performance units that vest over

multiple years, which aligns the interests of executive officers to long-term shareholder interests; and

• Executive officers are subject to share-ownership guidelines.

EXECUTIVE COMPENSATION METHODOLOGY

The Executive Compensation Committee

The Committee has the responsibility for reviewing, approving and recommending our executive compensation program to the Board for approval.

The role of the Committee is to oversee our compensation and benefit plans and policies, delegate responsibility for the administration of these plans

and review and approve annually all compensation decisions relating to our executive officers, including compensation decisions for our named

executive officers.

The Committee’s practice is to review our executive officer compensation program and make specific decisions in February of each year, including

review and approval of: base salaries; the achievement of annual short-term cash incentive goals for the prior year and corresponding payouts;

annual short-term cash incentive program thresholds, targets and maximums for the current fiscal year; the level of vesting of long-term incentive

grants that were eligible to vest during the year; and new long-term incentive grants. This review coincides with our Board's review of our financial

and operating results for the most recently completed year and allows the Committee to consider those results, as well as our financial and operating

plan for the upcoming year, as it makes compensation decisions. The Committee submits its recommendations regarding the compensation of our

chief executive officer, our other named executive officers and our non-management directors to the Board for approval.

The Committee recognizes the importance of maintaining sound basic principles for the development and administration of our compensation and

benefit programs. The Committee has adopted practices to enhance the Committee’s ability to carry out its responsibilities effectively, as well as to

ensure we maintain strong links between executive pay and performance. Examples of practices the Committee has adopted include:

• Holding executive sessions without company management present at every meeting of the Committee;

• Reviewing total compensation tally sheets for the named executive officers on an annual basis;

78 2025 ONEOK, Inc. Proxy Statement

Executive Compensation Discussion and Analysis

• Engaging an independent compensation consultant to advise the Committee on executive compensation issues;

• Meeting with the independent compensation consultant in executive session without management present at each regularly scheduled meeting of

the Committee to discuss our compensation program and actions on a confidential basis;

• Evaluating the performance of the Committee each year; and

• Assessing the performance of the Committee’s independent compensation consultant each year.

Following our 2024 annual meeting of shareholders, the Committee took into account the 95.4 % affirmative vote of our shareholders who voted on

our executive compensation , including abstentions, and determined to continue to apply the same principles the Committee has used historically in

determining the nature and amount of executive compensation.

The Role of Executive Management in the Executive

Compensation Process

Each year, our executive management presents our annual strategic and financial plan to our Board for approval. The presentation includes a review

of the expected financial and operating performance of each of our business segments, the expected financial performance of the company on a

consolidated basis, and a capital expenditure plan, as well as a consolidated five-year strategic and financial outlook. The criteria and targets for our

annual short-term cash incentive awards are recommended by executive management to the Committee based on our Board-approved strategic and

financial plan. Upon the completion of each fiscal year, and following finalization of the year’s financial and operating results, executive management

reviews our actual performance relative to the short-term incentive plan criteria and targets established by the Committee for the performance year in

order to determine the annual short-term cash incentive award recommendations to be presented to the Committee for each named executive officer.

In making individual compensation decisions, the Committee reviews the recommendations of the chief executive officer with respect to all named

executive officers other than himself. The Committee reviews and discusses these recommendations in executive session and reaches its own

decisions with respect to the compensation of the named executive officers, including the chief executive officer. In turn, the Committee presents its

compensation decisions with respect to the chief executive officer and the other named executive officers to the Board for approval.

The compensation group in our human resources department supports both the Committee and executive management in establishing

management’s recommendations regarding annual performance metrics and targets and providing periodic analyses and reports regarding our

executive compensation program.

The Role of the Independent Compensation Consultant

The Committee has the authority under its charter to engage the services of outside advisors, experts and others to assist the Committee in the

performance of its duties. During 2024, the Committee continued the engagement of Meridian Compensation Partners to serve as the Committee’s

independent compensation consultant on matters related to executive and director compensation. The independent compensation consultant reports

directly to the Committee and provides no other services to us.

The Committee annually reviews and establishes the scope of the engagement of the Committee’s independent compensation consultant, which is

reflected in an annual engagement letter between the consultant and the Committee. During 2024, the scope of the assignment and the material

instructions regarding the services of the consultant were to:

• Provide input to the Committee’s decision-making with respect to executive compensation matters in light of our business strategy, pay

philosophy, prevailing market practices, shareholder interests and relevant regulatory mandates;

• Provide advice on our executive pay philosophy;

• Provide advice on the composition of our compensation peer group for competitive benchmarking;

• Provide comprehensive competitive market studies as background against which the Committee can consider the company’s chief executive

officer and senior management base salaries, annual bonus opportunities, long-term incentive awards, benefits, perquisites and

severance protections;

• Provide incentive plan design advice for both annual and long-term incentive programs and other compensation and benefit programs to meet

our objectives;

• Apprise the Committee of emerging best practices and changes in the regulatory and corporate governance environment;

2025 ONEOK, Inc. Proxy Statement 79

Executive Compensation Discussion and Analysis

• Provide consulting and competitive market data on director compensation matters;

• Conduct periodic meetings with our management as required from time to time to discuss executive compensation issues and prepare for

Committee meetings;

• Assist with the preparation of our annual proxy statement “Executive Compensation Discussion and Analysis”;

• Review tally sheets regarding the company’s chief executive officer and other senior officers as developed by management; and

• Periodically review the Committee’s charter.

In addition, the engagement letter provides for the consultant to be available to assist the Committee with respect to other executive compensation

matters that may arise throughout the year.

The independent compensation consultant attended each regularly scheduled meeting of the Committee in 2024. During a portion of each regular

meeting, the independent compensation consultant met with the Committee in executive session without members of management present.

The independent compensation consultant also communicated with members of the Committee outside of the Committee’s meetings as desired by

the Committee members. The independent compensation consultant reviewed briefing materials, including those with respect to individual

compensation matters prepared by management for the Committee, reviewed recommendations and proposals being submitted to the Committee

and provided perspective, advice and recommendations to the Committee regarding the recommendations of management. The independent

compensation consultant also gathered and provided competitive market data and other background information for consideration by the Committee.

It is the Committee’s view that its independent compensation consultant should be able to render candid and direct advice independent of

management’s influence and numerous steps have been taken to satisfy this objective. The independent compensation consultant is engaged by

and reports directly to the Committee on matters related to compensation. As noted above, representatives of the independent compensation

consultant meet separately with the Committee members outside the presence of management at each regular meeting and also speak separately

with the Committee chair and other Committee members between meetings, as necessary or desired. The independent compensation consultant

interacts from time to time directly with our senior vice president and chief human resource officer, vice president, deputy general counsel -

compliance & ethics and corporate secretary, and our compensation department as necessary to support the work of the independent compensation

consultant on behalf of the Committee. These interactions are limited to those that are on the Committee’s behalf or related to matters that will be

presented to the Committee for review and approval.

At least annually, the Committee conducts a review of the independent compensation consultant’s performance and independence. This review

includes an evaluation of the services that the independent compensation consultant has provided to the Committee, the related fees and the

procedures implemented by the independent compensation consultant with respect to maintaining its independence. During 2024, Meridian

Compensation Partners did not advise us or deliver any services other than the referenced compensation consulting services provided to the

Committee. We incurred fees and expenses of $392,359 with Meridian Compensation Partners for compensation-related services to the

Committee in 2024.

In February 2024, the Committee considered the independence of Meridian Compensation Partners in light of Securities and Exchange Commission

rules and NYSE listing standards regarding the independence of consultants to compensation committees. The Committee requested and received a

letter from Meridian Compensation Partners addressing the consulting firm’s independence, including the following factors: (i) other services provided

to us by the consultant; (ii) fees paid by us as a percentage of the consulting firm’s total revenue; (iii) policies or procedures maintained by the

consulting firm that are designed to prevent conflicts of interest; (iv) any business or personal relationships between the individual consultants

involved in the engagement and any member of the Committee; (v) any company stock owned by the individual consultants involved in the

engagement; and (vi) any business or personal relationships between our executive officers and the consulting firm or the individual consultants

involved in the engagement. The Committee discussed these considerations and concluded that the work of the consultant did not raise any conflict

of interest and that the consultant was independent of the Committee and our company, and is providing effective counsel and services to

the Committee .

Competitive Assessment

For 2024 compensation decisions, the Committee asked Meridian Compensation Partners to assist it with the annual competitive assessment of our

executive compensation program. The Committee reviewed independent executive compensation data compiled by Meridian Compensation Partners

in November 2023 to assess competitive executive compensation levels for our executive officers.

80 2025 ONEOK, Inc. Proxy Statement

Executive Compensation Discussion and Analysis

The Committee considers a number of factors in structuring our compensation program and making compensation decisions, including the

compensation practices of selected peer companies in the energy industry, which we refer to as our “Energy Peers.” The Committee’s independent

compensation consultant annually reviews the peer group with the Committee to assess its continued appropriateness and applicability to our

company. The 2024 Energy Peers were recommended by Meridian Compensation Partners and management and were selected because they have

significant lines of business in the energy industry that are similar to our businesses in focus, ownership structure, affiliations and geography and

because the size of their operations (e.g., enterprise value, market value, and earnings before interest, taxes, depreciation and amortization) and the

skills and experience required of their senior management to effectively operate their businesses are also similar to our businesses. Companies that

have similar lines of business but have a history of anomalous pay practices, as determined by the Committee in consultation with our independent

compensation consultant, are excluded from consideration as a potential Energy Peer.

For 2024, the following changes were made to the Energy Peers we used for 2023 due to the company's increased size after the Magellan

acquisition:

Removals:

Magellan Midstream Partners, L.P. was removed from the group due to our acquisition of Magellan on September 25, 2023. EnLink Midstream, LLC,

Equitrans Midstream Corporation, and NuStar Energy, L.P. were removed from the group due to their smaller size when compared to ONEOK

following our acquisition of Magellan.

Additions:

Diamondback Energy, Inc., Hess Corporation, Marathon Petroleum Corporation, and Phillips 66 were added to the group due to their size-

appropriateness (primarily enterprise value, total assets, and gross profit) and relevant midstream operations when compared to ONEOK following

our acquisition of Magellan.

The Committee believes that reference to the Energy Peers is appropriate when reviewing our compensation program because we compete with

these companies for executive talent.

Marathon Petroleum Corporation Phillips 66 Plains All American Pipeline, L.P. Targa Resources Corp.	TC Energy Corporation The Williams Companies, Inc. Western Midstream Partners, LP

The Committee attempts to set the compensation opportunities of our executive officers at levels that are competitive with those of the Energy Peers

and uses market comparison data for these companies as a guide. The Committee reviews the median salary, annual short-term cash target

incentive and long-term target equity compensation (and the total of these elements) of persons holding the same or similar positions as our named

executive officers at the Energy Peers, based on the most recent market data available. The Committee then generally seeks to set each element of

the compensation of our named executive officers within a competitive range of the Energy Peers median level for such element, assuming payout of

performance-based compensation at target.

Market comparison data, however, is just one of the tools the Committee uses to determine executive compensation, and the Committee retains the

flexibility to set target compensation opportunities at levels it deems appropriate for an individual or for a specific element of compensation. An

executive’s actual compensation may vary from the target amount set by the Committee based on individual and company performance, as well as

changes in our stock price.

To assess the relative competitiveness of compensation for each named executive officer, the Committee’s established practice is to review the

Energy Peers’ base salary, short-term incentives, long-term incentives and total target compensation opportunities for the 25th, 50th and 75th

percentiles. For 2024, the total target compensation established b y the Committee for each of our named executive officers was between the 25th

and 75th percentiles, and therefore the Committee determined that 2024 compensation levels fell within the Committee’s established parameters.

Executive Compensation Discussion and Analysis

Tally Sheets

In February 2024, the Committee reviewed compensation tally sheets with respect to our named executive officers to better understand their total

executive compensation packages and gain further perspective when making pay decisions. Each of these tally sheets presented the dollar amount

of each component of the named executive officer’s compensation reviewed, including current cash compensation (base salary and any annual

short-term cash incentive payment), accumulated deferred compensation balances, outstanding long-term equity awards, retirement benefits,

incidental or one-time perquisites and any other compensation. These tally sheets also reflected potential payments under certain termination-of-

employment and change-in-control scenarios.

Compensation Mix and At-Risk Pay

In determining the overall mix of 2024 compensation for our named executive officers, the Committee considered the competitive market data

assembled by its independent compensation consultant in order to assess an appropriate allocation between cash and non-cash compensation.

A significant portion of total executive compensation is variable and “at-risk” based on both the annual and long-term performance of our company,

which aligns the interests of our executives with the interests of our shareholders. In 2024, consistent with our pay-for-performance philosophy, we

granted to our named executive officers performance units (having a value equal to approximately 80% of the aggregate equity grant value) and

time-vesting restricted units (having a value equal to approximately 20% of the aggregate equity grant value). In addition, the payment of long-term

incentive compensation in the form of our common stock helps to align the interests of our executive officers with the interests of our shareholders

and assists our executives in establishing a meaningful ownership position in our company in keeping with our share-ownership guidelines.

Personal Performance

Executive compensation decisions include an assessment of individual performance, including each named executive officer’s contribution to our

overall performance for the applicable performance period. Individual performance criteria include:

• Business results achieved;

• Problem analysis;

• Directing business activities;

• Utilization of human, capital and material resources;

• Initiation of and response to change;

• Leadership, planning and organizational abilities;

• Decision making;

• Time management;

• Communication and employee relations;

• Safety and environmental performance;

• Regulatory compliance; and

• Customer satisfaction.

The Committee, in consultation with our Corporate Governance Committee, completes an individual performance assessment of the chief executive

officer each year. This performance assessment is summarized and presented to the chief executive officer for discussion and is reviewed by the

Committee in executive session when evaluating the compensation of the chief executive officer. The other named executive officers are also

evaluated each year through our performance appraisal process by the chief executive officer. These performance assessments are considered

each year in connection with the overall compensation review process for our executives.

There are no differences in the Committee’s compensation policies and practices for determining the compensation awarded to the chief executive

officer and the other named executive officers other than as described in the paragraph above. Differences in levels of compensation are attributable

to differences in roles and responsibilities, experience, individual performance and the Committee’s practice of setting pay levels to reflect

competitive market conditions on a position-by-position basis.

Executive Compensation Discussion and Analysis

COMPONENTS OF COMPENSATION

Total Compensation

The Committee strives to provide a comprehensive executive compensation program that is competitive and meaningfully performance based.

To that end, a majority of our executive compensation is tied directly to our operating and financial performance. In structuring executive

compensation, the Committee considers long- and short-term financial performance, shareholder return, business unit performance, safety,

environmental and regulatory compliance, the previously referenced individual performance criteria, retention considerations and market data.

In setting the elements and amounts of compensation, the Committee generally does not consider amounts of compensation realizable from prior

years’ compensation. However, when making grants of long-term, equity-based incentive grants each year, the Committee considers, among other

factors it deems relevant, the size of grants of long-term, equity-based compensation made in prior years.

Annual Cash Compensation

As in prior years, annual cash compensation in 2024 for the named executive officers consisted of two components: base salary and a variable,

at-risk, 2024 short-term incentive award based on both the company’s financial and operating performance and the executive officer’s individual

performance.

• Base Salar y. Annual base salary is designed to compensate executives for their level of responsibility, experience, tenure, sustained individual

performance and contributions to our company. Salaries are reviewed annually. While the Committee considers our overall financial performance

in establishing levels of executive compensation each year, there are no specific, objective financial results that are quantified by the Committee

in establishing or changing the base salaries of our named executive officers.

• 2024 Short-Term Incentive Awards. Variable, at-risk, 2024 short-term incentive awards were made under our Annual Officer Incentive Plan and

designed to communicate collective annual corporate goals, to provide our named executive officers with a direct financial interest in our

performance and profitability and to reward annual performance. The 2024 performance goals established under the Annual Officer Incentive

Plan and the company’s performance relative to such goals are described under “2024 Short-Term Incentive Awards.”

Long-Term Equity Incentive Awards

Grants of equity-based compensation are made pursuant to the 2018 EIP. Typically, these grants consist of restricted units and performance units to

our named executive officers and other eligible participants. These annual grants are designed to provide a meaningful incentive to enhance long-

term shareholder value. A higher ratio of performance units to restricted units is granted to higher-level officers and those with more direct ability to

impact the performance of the company.

Retirement Benefits

We have a defined contribution retirement plan (“401(k) Plan”) covering our employees, including our named executive officers, and we match 100%

of employee contributions under this plan up to 6% of eligible compensation each payroll period . Beginning with 2024, a true-up matching

contribution was approved for employees who are employed on the last day of the year (or terminated on account of death, disability or retirement).

The true-up matching contribution equals 100% of the first 6% of eligible compensation contributed by the employee for the year, minus any

matching contributions previously made for the year. The 401(k) Plan also includes a profit-sharing feature for employees who do not actively accrue

benefits in our defined benefit pension plans . Messrs. Norton, Hulse, Burdick, and Taylor each received a profit-sharing contribution each calendar

quarter during 2024 under the profit-sharing feature of our 401(k) Plan equal to 1% of eligible compensation for that quarter and an additional,

discretionary contribution after year end equal to 6% of eligible 2024 compensation . The ONEOK, Inc. Retirement Plan ("Retirement Plan") covers

Mr. Swords and certain other employees hired prior to January 1, 2005, or pursuant to an acquisition from Koch Industries on July 1, 2005, and it

provides a monthly retirement benefit based on the participant’s final average earnings, age and years of service.

In addition, we maintain a Supplemental Executive Retirement Plan, a nonqualified defined benefit pension plan that provides benefits in excess of

maximum benefit accruals under our Retirement Plan due to applicable limits under the Internal Revenue Code, for certain officers who participate in

our Retirement Plan. Of our named executive officers, Mr. Swords is the only participant in the Supplemental Executive Retirement Plan. No new

participants in our Supplemental Executive Retirement Plan have been approved since 2005 and the plan was closed to new participants in 2013.

Additional details regarding our Retirement Plan and Supplemental Executive Retirement Plan are provided under “Pension Benefits.”

2025 ONEOK, Inc. Proxy Statement 83

Executive Compensation Discussion and Analysis

We also sponsor employee health and welfare plans that provide post-retirement medical and life insurance benefits to eligible employees (including

our named executive officers) hired prior to January 1, 2017 . The pre-Medicare post-retirement medical plan is contributory, with retiree contributions

adjusted periodically, and contains other cost-sharing features such as deductibles and co-insurance. The post-retirement medical plan for

Medicare-eligible retirees is an account-based plan pursuant to which certain employees are eligible for company contributions that can be applied

toward the purchase of individual Medicare supplement policies through a private exchange.

Nonqualified Deferred Compensation Plan

Our 2020 Nonqualified Deferred Compensation Plan (“NQDC Plan”), the successor plan to our two prior nonqualified deferred compensation plans

("Prior NQDC Plans," and collectively with the NQDC Plan, the "NQDC Plans"), is available to a select group of management and highly

compensated employees, including our named executive officers. The NQDC Plan permits participants to defer receipt of a portion of their

compensation to be earned during the following year until a later date permitted under the NQDC Plan and provides notional employer contributions

to compensate participants who are subject to certain limits established by the Internal Revenue Code of 1986, as amended (the “Tax Code”), with

respect to their qualified plan benefits. Because these arrangements are, by their nature, tied to cash compensation and qualified plan benefits, they

are not considered by the Committee when establishing salary and short-term and long-term incentive measures and amounts. Historically, officers

also were eligible to defer the receipt of their performance unit awards into the Prior NQDC Plans.

Perquisites and Other Benefits

The company provides only minimal perquisites to the named executive officers, which are not taken into account by the Committee when

establishing salary and short- and long-term incentive compensation.

2024 COMPENSATION DECISIONS

For each of our named executive officers, 2024 base salary and short- and long-term incentive targets were determined in February 2024 following

consideration of the business and economic environment, market data for the Energy Peers compiled and furnished by the independent

compensation consultant to the Committee, internal equity considerations and a subjective determination of the officer’s individual performance using

the performance criteria referenced above.

The Committee does not use objective targets when evaluating performance with respect to those individual performance criteria and does not have

a specific weighting for any of the individual performance factors. The final determination is based upon all of the individual performance criteria,

considered in the aggregate and in light of the surrounding circumstances, but such determination and the assessment of each individual factor is

entirely subjective. The Committee includes and reviews those subjective factors to ensure that it undertakes a comprehensive review of individual

performance when setting compensation.

The Committee’s primary recommendations to our Board, which the Board subsequently approved in February 2024, regarding the 2024

compensation of our named executive officers are summarized below. These actions are consistent with our compensation philosophy described on

pages 76 - 77 :

Name	Base Salary — 2024	2023	Short-Term Incentive Target — 2024	2023	Long-Term Incentive Target — 2024	2023
Pierce H. Norton II	$ 925,000	$ 835,000	150%	125%	$ 8,000,000	$ 5,000,000
Walter S. Hulse, III	$ 650,000	$ 600,000	110%	100%	$ 3,250,000	$ 2,200,000
Kevin L. Burdick	$ 550,000	$ 500,000	95%	95%	$ 1,800,000	$ 1,600,000
Sheridan C. Swords	$ 525,000	$ 500,000	95%	85%	$ 1,800,000	$ 1,250,001
Lyndon C. Taylor	$ 600,000	$ 550,000	95%	90%	$ 1,850,000	$ 500,000

• Increasing Mr. Norton’s base salary by $90,000 ( 10.8% ), short-term incentive target by 25 percentage points, and his long-term incentive target

by $3,000,000 ( 60.00% ).

• Increasing Mr. Hulse’s base salary by $50,000 ( 8.3% ), short-term incentive target by 10 percentage points, and his long-term incentive target by

$1,050,000 ( 47.7% ).

• Increasing Mr. Burdick’s base salary by $50,000 ( 10.0% ) and his long-term incentive target by $200,000 ( 12.5% ).

84 2025 ONEOK, Inc. Proxy Statement

Executive Compensation Discussion and Analysis

• Increasing Mr. Swords' base salary by $25,000 ( 5.0% ), short-term incentive target by 10 percentage points, and his long-term incentive target by

$549,999 ( 44.0% ).

• Increasing Mr. Taylor's base salary by $50,000 ( 9.1% ), short-term incentive target by 5 percentage points, and his long-term incentive target by

$1,350,000 ( 270.0% ). Mr. Taylor's long-term incentive target increase for fiscal year 2024 is primarily attributable to the timing of his hire date

occurring in October 2023. As Mr. Taylor joined the Company late in the fiscal year, his initial long-term incentive target reflected his partial-year

service. The subsequent long-term incentive target in February 2024 represents the full annual target consistent with the Company's typical

annual grant cycle for executive officers.

We believe these actions establish target total compensation opportunities for our named executive officers within a competitive range of the median

of compensation opportunities awarded at our Energy Peers. We believe this positioning allows us to attract, motivate, and retain highly-qualified

executives in our industry. An individual’s competitive positioning will consider additional factors beyond market data (which increased after the

changes to the Energy Peers following the acquisition of Magellan), and these actions with respect to our named executive officers reflect company

performance; each named executive officer’s individual performance and contributions; the skills and experience of each named executive officer

and the scarcity and market demand for such skills and experiences; and other relevant factors, e.g. succession planning, and internal equity.

2024 SHORT-TERM INCENTIVE AWARDS

The purpose of our Annual Officer Incentive Plan is to align the named executive officers’ interests with shareholders’ interests by providing them

with a financial incentive tied directly to key measures of our financial and operational performance. The 2024 annual short-term cash incentive plan

measures and their weighting were developed and recommended to the Committee by executive management, were reviewed and approved by the

Committee, and were approved by our Board in February 2024.

Financial Measures

The 2024 Annual Officer Incentive Plan included the measurement of financial results that took into account the impact of anticipated market

conditions (commodity prices, natural gas liquids price differentials and natural gas and natural gas liquids volumes). The following financial

measures were included in the 2024 Annual Officer Incentive Plan:

• Earnings per share (EPS) , which measures the quantity of our earnings. EPS is net income available to common shareholders divided by the

weighted-average diluted shares outstanding for the fiscal year.

• Return on invested capital (ROIC) , which measures the quality and efficiency of our earnings and capital investments. ROIC is earnings before

interest and taxes (EBIT) divided by invested capital, where invested capital is the daily average for the fiscal year of short-term debt, less cash,

long-term debt and equity, excluding accumulated other comprehensive income.

• Note: EPS and EBIT exclude the effects of accounting changes, if any.

Operational Measures

The following operational measures were included in the 2024 Annual Officer Incentive Plan.

• Total Recordable Incident Rate (TRIR): TRIR is the number of Occupational Safety and Health Administration incidents per 200,000

work-hours. The inclusion of this metric is designed to emphasize our commitment to the safe operation of our business and to reward safe

behavior throughout our company.

• Agency Reportable Environmental Event Rate (AREER): AREER is defined as the total number of releases and excess emission events that

trigger a federal, state or local environmental reporting requirement (with some exceptions to account for events outside our control, planned

maintenance and disparities in reporting requirements across our operations) per 200,000 work-hours.

Goal Setting

The Committee also approved threshold, target and maximum levels for each financial and operational measure. These levels were set based on the

expectation of: (i) a high likelihood the threshold level of performance would be achieved; (ii) a reasonable likelihood the target would be achieved;

and (iii) a low likelihood the maximum would be achieved.

2025 ONEOK, Inc. Proxy Statement 85

Executive Compensation Discussion and Analysis

In setting the threshold, target and maximum levels for each financial and operational measure for the 2024 Annual Officer Incentive Plan, the

Committee considered the September 2023 Magellan acquisition and its expected impact on each measure in 2024. For example, the EPS measure

would be impacted by, among other things, the expected full year contributions of the Refined Products and Crude segment on net income and the

additional ONEOK shares issued as part of the Magellan acquisition. The ROIC measure would be impacted by, among other things, the expected

full year contributions of the refined products and crude segment on EBIT and higher expected invested capital associated with the Magellan

acquisition. The TRIR and AREER measures would be impacted by use of a three-year weighted average of ONEOK and Magellan incident and

event rates. As a result, the goals set for the 2024 Annual Officer Incentive Plan were established without regard for the 2023 Annual Officer

Incentive Plan, which were not comparable.

Based upon the company’s performance against these measures, annual short-term cash incentive awards for 2024 company performance could

range from zero to a maximum of 200% of target. In determining the actual annual short-term incentive award to be paid to each named executive

officer, assuming the company’s performance measures are met, the award may be adjusted based for individual performance, which is measured

based on the individual’s contributions to achieving our corporate goals. As in past years, tying the annual short-term cash incentive award to

individual performance raises the level of personal accountability for each named executive officer.

The 2024 metrics and targets are summarized as follows :

ONEOK, Inc. Corporate Performance Criteria 2024 Fiscal Year — Earnings per share (EPS)	$ 4.25	$ 4.80	$ 5.36	Weighting — 40%	Target Payout — 40%	Maximum Payout — 80%
Return on invested capital (ROIC)	11.69%	12.81%	13.92%	40%	40%	80%
Total recordable incident rate (TRIR)	0.60	0.40	0.30	10%	10%	20%
Agency reportable environmental event rate (AREER)	1.11	0.74	0.56	10%	10%	20%
			Total	100%	100%	200%

For each performance measure in the table above, no incentive amount would be paid for that measure if the company’s actual result did not meet

the threshold level. If our actual result was between the stated performance levels, the percentage payable was interpolated between the stated

payout percentages on a linear basis. The cumulative corporate payout percentage achieved for 2024 was 183.5% of target.

In addition to taking into account the established corporate criteria, annual short-term cash incentive awards to the named executive officers are

subject to further adjustment through the application of an individual performance modifier generally ranging from zero to 125% of the payout

percentage established by the scorecard above. The individual performance modifier is set by the Committee annually, taking into consideration

management’s recommendation regarding individual performance and contribution. However, the Committee itself sets Mr. Norton’s individual

performance modifier after considering his performance and contribution. Management makes no recommendation to the Committee regarding

Mr. Norton’s individual performance modifier.

The Annual Officer Incentive Plan provides that, in the event of a change in control, each participant in the plan shall be paid a short-term incentive

award that is not less than the prorated portion of the incentive award the participant would have otherwise received for that plan year through the

date of such change in control; provided, however, that the company will assume that all thresholds and targets as specified for the plan year have

been met and that the short-term incentive award will be reduced by any amount otherwise payable by the company to the participant under any

other plan, agreement or arrangement based on substantially the same performance goals applicable for that period of time and performance,

including our Change in Control Severance Plan.

Impact of EnLink and Medallion Acquisitions on 2024

ONEOK STIP

In February 2024, the company’s acquisitions of EnLink and Medallion were not among the considerations when the annual short-term cash

incentive plan performance goals were approved by the Committee and our Board.

In November 2024, the Committee, along with executive management and Meridian Compensation Partners, began reviewing the potential impact of

the EnLink and Medallion acquisitions. It was apparent that the consummation of the acquisition of the managing member interest in EnLink on

October 15, 2024, and the consummation of the Medallion acquisition on October 31, 2024 would impact the plan’s financial measures – EPS and

ROIC. As to the plan’s operational measures – TRIR and AREER – both remained measurable through year-end with minimal impact due to the

acquisitions .

86 2025 ONEOK, Inc. Proxy Statement

Executive Compensation Discussion and Analysis

In November 2024, executive management and Meridian Compensation Partners recommended for the Committee’s consideration that the projected

EPS and ROIC payout factors for the 2024 short-term incentive plan should exclude the impact of the EnLink and Medallion acquisitions, but include

any smaller acquisitions during 2024.

Executive management and Meridian Compensation Partners believed the recommended approach and adjustments described below are well within

market practice for similar situations.

In addition, the recommended approach retained certain "Guiding Principles" to inform any Committee decision related to the determination of

payouts for the plan's financial measures. Such principles included:

• Maintaining the company’s pay-for-performance philosophy;

• Holding management accountable for financial results through year-end;

• Treating participants fairly;

• Avoiding or limiting complexity;

• Limiting the need for Committee discretion;

• Communicating the impact to participants to eliminate uncertainty; and

• Supporting employee engagement during a time of significant transition.

After thorough discussion, review, and consideration, the Committee and our Board at their respective meetings on November 6, 2024 concurred in

the recommended approach to exclude the impact of the EnLink and Medallion acquisitions when calculating the EPS and ROIC payout factors for

the 2024 annual short-term incentive plan.

As a result, the following measurement approach designed to exclude the impact of the EnLink and Medallion acquisitions was used:

Metric	Measurement Approach	Comment
EPS	Full-year earnings (net of adjustments described below) for legacy ONEOK business, divided by weighted- average diluted shares outstanding from 1/1/2024 through 12/31/2024.	Neutralizes impact of acquisitions.
ROIC	Full-year EBIT (net of adjustments described below) for legacy ONEOK business, divided by daily average invested capital from 1/1/2024 through 10/31/2024.	Neutralizes impact of acquisitions, including changes to capital base.

Such approach included:

• Exclusion of transaction costs (e.g., fees paid to financial, legal, accounting and other advisors, severance costs, etc.); and

• Adjustment for impact of borrowing funds to pay the cash portion of the purchase price (both interest income and interest expense).

2024 Results

The following table sets forth the 2024 target and maximum award opportunity for each of the named executive officers expressed as a percentage

of base salary.

Name	Target Award as Percentage of Base Salary	Maximum Award as a Percentage of Base Salary
Pierce H. Norton II	150.0%	375.0%
Walter S. Hulse, III	110.0%	275.0%

2025 ONEOK, Inc. Proxy Statement 87

Executive Compensation Discussion and Analysis

At the regular meeting of the Committee held in February 2025, the Committee determined that payouts under the 2024 Annual Officer Incentive

Plan would be based on a 183.5% corporate modifier. This determination was made following the calculation of the year-end results of the

company’s achievement with respect to the four objective performance criteria referenced above. The percentage modifier was calculated based on

a sum of the following determinations:

• The 2024 EPS , as adjusted for the EnLink and Medallion acquisitions, was $5.25, which was greater than the target goal. As a result, a weighted

payout of 72.1% of target was earned toward the overall corporate modifier;

• The 2024 ROIC, as adjusted for the EnLink and Medallion acquisitions, was 13.71%, which was greater than the target goal. As a result, a

weighted payout of 72.4% of target was earned toward the overall corporate modifier;

• The 2024 TRIR performance was 0.31 , which was between the target and maximum goals. As a result, a weighted payout of 19% of target was

earned toward the overall corporate modifier; and

• The 2024 AREER was 0 .33 , which achieved the maximum goal. As a result, a weighted payout of 20% of target was earned toward the overall

corporate modifier.

These performance measure percentages were added together to arrive at the 183.5% corporate modifier.

• The 2024 TRIR performance of 0.31 was 22.5% below the 2024 target goal of 0.40 (representing above target performance) . The 2024 AREER

result of 0.33 was 55% below the 2024 target goal of 0.74 (representing above target performance). For more information about the history of our

AREER operational measure, see page 47 . The continued safe, reliable and environmentally sustainable operation of our network of integrated

natural gas, natural gas liquids, refined products and crude oil assets is essential to our business success.

In addition, the Committee assigned individual performance modifiers to each of the named executive officers as follows under our 2024 short-term

incentive plan in recognition of each individual’s performance and contribution during the year:

Mr. Norton , 110% Mr. Hulse , 125% Mr. Burdick , 120% Mr. Swords , 115% Mr. Taylor , 125%

• To determine the short-term awards payable to each of our named executive officers for 2024, the company’s 183.5% modifier was multiplied by

the named executive officer’s base salary, times his or her target short-term incentive percentage as set forth in the table above, and times his or

her individual performance modifier as described above. The annual calculation for our named executive officers may be summarized as follows:

SHORT-TERM INCENTIVE AWARD CALCULATION:

$55,000	0.06	0.9	1.835	$5,450
Base salary at December 31	STI target based on a percentage of base salary	Individual employee performance modifier (0 to 125%)	Company performance modifier (0 to 200%)	Employee incentive award (rounded to nearest $100)

Note: If an employee has been with the company for less than a year or if they worked part-time for any portion of the year, the incentive award is prorated to

reflect that.

The Committee did not exercise its discretion to adjust the amount of the 2024 corporate modifier for extraordinary circumstances.

The “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table for Fiscal 2024 on page 93 contains the annual

short-term incentive awards under the Annual Officer Incentive Plan earned by each of the named executive officers for 2024 and paid in 2025.

2024 LONG-TERM INCENTIVE AWARDS

Overview

The objectives of our long-term incentive program are to motivate and reward executives and other key employees for sustained long-term

performance and to promote their retention. We do not grant stock options, and no options are held by named executive officers. Participation in our

2018 EIP is limited to those officers and employees who are in a position to contribute significantly to our long-term growth and profitability. The 2018

EIP is administered by the Committee, and the Committee is authorized to make all future grants of long-term incentive awards, as well as to make

all decisions and interpretations required to administer the plan.

Equity-based long-term incentive awards are generally approved and granted on an annual cycle, typically in the first quarter of each year. Awards

made by the Committee in February 2024 were based upon competitive market data provided to the Committee by the Committee’s independent

compensation consultant; the Committee’s assessment of our overall performance and the individual executive’s performance and contribution as

well as Mr. Norton’s recommendations for named executive officers other than himself. The Committee also considered the size of equity grants

made in prior years to each executive.

2024 Awards

Consistent with our pay-for-performance philosophy, ONEOK’s long-term incentive program is designed to place significant emphasis on

performance with approximately 80% of named executive officers’ long-term incentive opportunity awarded in performance-vested stock unit awards

and the remaining 20% awarded in time-vested restricted unit awards.

The aggregate grant date fair value of the restricted units and performance units granted to the named executive officers in 2024, as determined in

accordance with ASC Topic 718, is shown in the “Stock Awards” column of the Summary Compensation Table for Fiscal 2024 on page 93 .

2024 Restricted Units. Restricted units were granted to named executive officers in 2024 to enhance retention and further align their interests

with shareholders.

Restricted units granted in 2024 will vest at the end of a designated period, typically three years from the date of grant, at which time the holder is

entitled to one share of our common stock for each restricted unit held. If a holder of restricted units retires, becomes disabled, dies or is involuntarily

terminated without cause prior to vesting, the restricted units will vest immediately on a prorated basis based on the number of full months elapsed

from the date of grant to the date of such holder’s retirement, disability, death or termination. If the holder is terminated involuntarily without cause, or

terminates voluntarily for good reason, within two years after a qualifying change in control of the company, restricted unit awards will immediately

vest on the date of such termination. In cases of termination of employment for any reason other than (i) retirement, disability, or death, (ii) an

involuntary termination of employment by the company without cause, or (iii) a voluntary termination of employment for good reason in connection

with a qualifying change in control event, restricted units are forfeited. Dividend equivalents are accrued with respect to these restricted units over the

term of the vesting period and are paid when the units vest.

2024 Performance Units. Performance units were granted to named executive officers in 2024 to further align their compensation with the long-term

performance of the company and link their interests directly to those of the company’s shareholders.

Performance units granted in 2024 will vest on February 17, 2027, at which time the holder will be entitled to receive a percentage of the

performance units granted in shares of our common stock. Beginning with the 2024 grant, the three-year performance period, which for previous

cycles began in mid-to-late February, was changed to three calendar years (January 1, 2024 - December 31, 2026). The number of shares of

common stock to be issued upon vesting will range from zero to 200% of the number of units granted based on our cumulative total shareholder

return (“TSR”) for the performance period compared with the TSR of the peer group established for 2024 performance units. We use separate peer

groups for purposes of benchmarking named executive officer compensation and for calculating relative TSR under our performance units. Our

relative TSR peers for 2024 consist of companies in the midstream industry with similar lines of business and is comprised of the following

companies: Antero Midstream Corp.; DT Midstream, Inc.; Energy Transfer, L.P.; Enterprise Products Partners L.P.; Kinder Morgan, Inc.; Kinetik

Holdings, Inc.; MPLX LP; Plains All American Pipeline, L.P.; Targa Resources Corp.; Western Midstream Partners, LP; and The Williams

Companies, Inc. For 2024, we also removed some companies from this peer group due to merger and acquisition activity, including NuStar Energy

L.P. due to its acquisition by Sunoco LP on May 3, 2024; Equitrans Midstream Corp. due to its acquisition by EQT Corp. on July 22, 2024; and

EnLink Midstream LLC due to its acquisition by ONEOK on January 31, 2025. TSR includes both the change in market price of the stock and the

value of dividends (which are deemed reinvested in the stock) during the three-year performance period. Peer companies that are acquired by an

unrelated entity during the performance period are not considered in the performance calculation and any peer company that files for bankruptcy

protection remains in the peer group and is deemed to have a cumulative TSR of negative 100% for the performance period.

2025 ONEOK, Inc. Proxy Statement 89

Executive Compensation Discussion and Analysis

The following table reflects the percentage of units that will be earned at the end of the three-year performance period for 2024 performance units

based on our TSR performance during such period as compared with our peer group :

PERFORMANCE UNITS VESTING LEVELS 2024 — 2026 PERFORMANCE PERIOD

ONEOK TSR Ranking vs. Peer Group	Percentage of Performance Units Earned
90th Percentile and above	200%
75th Percentile	150%
50th Percentile	100%
25th Percentile	50%
Below 25th percentile	0%

If our TSR ranking at the end of the performance period is between the stated percentage levels set forth in the table above, the percentages of

performance units earned will be interpolated between the earnings levels.

If a holder of performance units retires, becomes disabled or dies prior to vesting, the performance units will vest on the vesting date based on the

performance results at the end of the performance period, prorated based on the period of time the holder was employed during the vesting period. If

the holder is terminated involuntarily without cause, terminates voluntarily for good reason, or terminates on account of retirement, disability, or

death, in each case before vesting and within two years after a qualifying change in control, the units will vest in the amount calculated pursuant to

the next sentence if the change in control occurs during the performance period, or the amount calculated based on actual TSR performance if the

change in control occurs after the performance period and before the vesting date. If the qualifying change in control occurs during the performance

period, the amount to be paid with respect to the units shall be determined based on the greater of (i) the target number of performance units

(prorated for termination before the vesting date, as described in the preceding sentence, based on the period of time employed during the vesting

period), or (ii) the number of units calculated for the performance period based on actual TSR performance as of the date of the change in control

(without proration) , in each case giving effect to the accumulated dividend equivalents. If a qualifying change in control occurs after the holder

terminates on account of retirement, disability, or death, and prior to vesting, the amount of units that vest will be calculated pursuant to the

preceding sentence. In all other cases of termination of employment, performance units are forfeited. Dividend equivalents are accrued with respect

to these performance units over the term of the vesting period and are paid when the units vest .

PAYOUT OF 2021-2024 PERFORMANCE UNITS

Performance units granted under the 2018 EIP were eligible to be earned based on our cumulative TSR during the three-year performance period

from February 17, 2021 to February 17, 2024, as compared with the cumulative TSR of a specified peer group of energy companies. As illustrated in

the table below, the number of shares of common stock to be issued upon vesting ranged from zero to 200% of the number of units granted based

on our relative TSR performance.

PERFORMANCE UNITS VESTING LEVELS FEBRUARY 2021 — FEBRUARY 2024 PERFORMANCE PERIOD

ONEOK TSR Ranking vs. Peer Group	Percentage of Performance Units Earned
90th Percentile and above	200%
75th Percentile	150%
50th Percentile	100%
25th Percentile	50%
Below 25th percentile	0%

Our cumulative TSR was at the 44th percentile relative to the specified peer group of energy companies during the performance period. As a result,

in February 2024, the Committee certified a payout equal to 88% of the target number of units granted and the named executive officers were

awarded an equivalent number of shares of our common stock.

Additional information regarding payouts of the 2021-2024 performance units is provided in the "Stock Vested in Fiscal Year 2024" table on page 97 .

Executive Compensation Discussion and Analysis

CLAWBACK POLICY

Effective as of October 2, 2023, we adopted a Compensation Recoupment Policy, which is intended to comply with the NYSE listing standards

adopted pursuant to Rule 10D-1 under the Exchange Act. Under the Compensation Recoupment Policy, if the company is required to prepare an

accounting restatement due to any material noncompliance with financial reporting requirements under applicable securities laws, we will be required

to recover from current and former executive officers any incentive-based compensation that was erroneously awarded to the executive officers

during the three years preceding the date that the company is required to prepare such restatement, unless the Committee determines that recovery

would be impracticable. Incentive-based compensation includes compensation that is granted, earned, or vested based wholly or in part on a

financial reporting measure.

If mandatory recovery is triggered under the Compensation Recoupment Policy due to an accounting restatement, we are required to recover the

excess of the amount of incentive-based compensation actually received by the executive officer over the amount of incentive-based compensation

that he or she would have received had payment been determined based on the restated financial measure.

In addition, the Compensation Recoupment Policy permits our Board or the Committee to use discretion to recover incentive-based cash and any

equity compensation granted to employees who have engaged in fraud, negligence or intentional misconduct that directly or indirectly results in a

restatement of all or a portion of our financial statements. We believe that these clawback provisions discourage employees from taking actions that

could result in material, excessive financial-reporting risk to us.

Our outstanding time-vesting restricted unit and performance unit grant agreements include acknowledgments from the grantee that the units

payable under such awards are subject to the Compensation Recoupment Policy or any company clawback policy in effect from time to time and, to

the extent permitted by applicable law, are subject to offset in the event that the grantee has an outstanding recoupment obligation under any such

clawback policy.

In addition, our Annual Officer Incentive Plan provides that all awards made under such plan are subject to the Compensation Recoupment Policy or

any company clawback policy as in effect from time to time.

In fiscal year 2024, we had no financial statement corrections requiring a restatement, and the Board has not needed to consider taking any action

under our Compensation Recoupment Policy or other clawback provisions. The foregoing summary does not purport to be complete and is qualified

in its entirety by reference to the full text of our Compensation Recoupment Policy, a copy of which is filed as Exhibit 97 to our Annual Report on

Form 10-K for the fiscal year ended December 31, 2024.

SECURITIES/INSIDER TRADING POLICY

We have an insider trading policy governing the purchase, sale and other dispositions of the company’s securities by directors, officers and

employees. The company believes that this policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and

listing standards applicable to the company. The policy provides that employees, including our officers and directors, may not purchase or sell our

stock when they are in possession of material non-public information. Further, the policy provides that the company will not engage in any

transactions involving our securities while it is aware of material non-public information relating to the company or our securities. This policy also

provides that officers, directors and employees in certain designated work groups may trade in our securities only during “open window” periods

(beginning on the third business day after our public release of quarterly or annual earnings and continuing until the first day of the following calendar

quarter) and must pre-clear all purchases and sales of our securities.

This policy also prohibits officers, members of our Board and employees in certain designated work groups from engaging in short sales, derivative

or speculative transactions in our securities, and from purchasing or using, directly or indirectly through family members or other persons or entities,

financial instruments (including puts or calls, prepaid variable forward contracts, equity swaps, collars and exchange funds) that are designed to

hedge or offset any decrease in the market value of our securities. For the purposes of this policy, “our securities” refers to the common stock,

preferred stock and debt issued by us or our respective divisions and subsidiaries, securities of other companies with significant relationship to us, as

well as derivative securities that relate to or derive their value from our common stock, debt or such other companies’ stock. The policy also prohibits

officers and directors from holding our securities in a margin account or pledging our securities as collateral for a loan. An exception to this

prohibition may be granted by the chief executive officer when an officer or director wishes to pledge shares of our stock as collateral for a loan (but

not including a margin account), the officer or director clearly demonstrates the financial capacity to repay the loan without resorting to the pledged

securities, and the terms of the loan prohibit the sale of any of our stock held as collateral at times when the officer or director is not permitted to

trade in our stock.

The foregoing summary does not purport to be complete and is qualified in its entirety by reference to the full text of our Securities/Insider Trading

Policy, a copy of which is filed as Exhibit 19.1 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

We are not aware of any named executive officer or member of our Board who has pledged any of their shares of our common stock.

Executive Compensation Discussion and Analysis

SHARE-OWNERSHIP GUIDELINES

Our Board strongly advocates executive share ownership as a means to align executive interests with those of our shareholders and has adopted

share-ownership guidelines for all officers of the company. These guidelines generally must be achieved by each officer over the course of five years

after becoming an officer or over the course of five years following promotion to a new office with a higher ownership guideline.

The ownership guideline for the chief executive officer is a share ownership position with a value of six times base salary. The ownership guidelines

for our other officers provide for share ownership positions ranging from two to four times base salary, depending on the office held:

Level	Position	Market Value of ONEOK Stock Held
LEVEL 1	Vice President	2 times base salary
LEVEL 2	Senior Vice President	3 times base salary
LEVEL 3	Executive Vice President	4 times base salary
LEVEL 4	President and Chief Executive Officer	6 times base salary

Shares that count toward the minimum ownership guideline include:

• Shares owned by the officer,

• Shares held in trust for the benefit of the officer or the benefit of the officer’s immediate family,

• Shares held in qualified plans, and

• Restricted units.

Performance unit shares that have not yet been earned and vested do not count toward the minimum ownership guidelines.

Our share-ownership guidelines provide that an officer may not sell shares of stock unless such officer holds shares that meet the minimum

ownership guideline after giving effect to such sale.

All officers were in compliance with these guidelines in 2024.

CHANGE IN CONTROL BENEFITS

Our executive management and other employees have built our company into the successful enterprise that it is today, and we believe that it is

important to protect their interests in the event of a change in control of our company. Further, it is our belief that the interests of our shareholders will

be best served if the interests of our senior management are aligned with those of our shareholders, and that providing change in control benefits

should mitigate any potential reluctance of executive management to pursue potential change in control transactions that may be in the best interests

of our shareholders.

We have a Change in Control Severance Plan that provides for certain payments (comprised of a single lump sum cash payment that may be up to

three times the sum of a participant’s base salary and target short-term incentive bonus, plus reimbursement of COBRA healthcare premiums for up

to 18 months) in the event of termination of employment involuntarily without cause or voluntarily for good reason of an executive officer of our

company (including the named executive officers) within the two years following a change in control (a so-called “double-trigger” plan). The plan does

not provide for additional pension benefits upon a change in control. Also, the plan provides plan participants a “net best” approach to excise taxes in

determining the benefit payable to a participant under the plan. This approach provides a participant his or her “net best benefit,” which is the greater

of (i) the full benefit payable to the participant net of the applicable federal excise tax, if any, or (ii) the benefit reduced to a level that would not trigger

the payment of federal excise tax. To determine the levels of benefits to be paid to the named executive officers, the Committee consulted with

Meridian Compensation Partners, its independent compensation consultant, to determine competitive practices in our industry with respect to change

in control arrangements. The Committee determined that the levels of benefits provided under the plan, including the payment of various multiples of

salary and target short-term incentive compensation, accomplished our objective of providing competitive benefits and that these benefits are

consistent with the general practice among our peers. The Committee annually reviews the eligible participants and benefit levels under the plan.

For additional information on this plan, see “Potential Post-Employment Payments and Payments Upon a Change in Control” below.

INTERNAL REVENUE SERVICE LIMITATIONS ON

DEDUCTIBILITY OF EXECUTIVE COMPENSATION

Under Section 162(m) of the Tax Code, the company will generally not be entitled to a tax deduction for individual compensation over $1 million that

is paid to certain executive officers. In 2024, the Committee once again compensated executive officers in a manner designed to promote varying

corporate goals in the best interest of the company. The Committee has not adopted a policy requiring all compensation to be fully deductible under

Section 162(m). The Committee will continue to consider the potential impact of the application of Section 162(m) on compensation for its executive

officers among other relevant considerations and reserves the right to provide compensation to executive officers that would not be tax-deductible if it

believes that doing so is aligned with the interests of the company and its shareholders.

2025 REPORT OF THE EXECUTIVE

COMPENSATION COMMITTEE

(1) The amounts included relate to restricted units and performance units granted under our 2018 EIP and reflect the aggregate grant date fair value calculated

pursuant to ASC Topic 718. Material assumptions used in the calculation of the value of these equity grants are included in Note L of the Notes to Consolidated

Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2024.

The aggregate grant date fair value of restricted units for purposes of ASC Topic 718 was determined based on the closing price of our common stock on the grant

date. With respect to the performance units, as market condition awards, the grant date fair value for purposes of ASC Topic 718 is the full grant date fair value, as

adjusted to reflect any increase or reduction in value that is appropriate for the probability that the market condition might or might not be met. For a discussion of

the assumptions used to calculate the value of performance unit awards, refer to Note L of the Notes to Consolidated Financial Statements included in our Annual

Report on Form 10-K for the year ended December 31, 2024. Using the maximum number of shares issuable upon vesting of the performance units (200% of the

units granted), the aggregate grant date fair value of the performance units with respect to 2024 would be as follows:

Name	2024
Pierce H. Norton II	$ 14,957,532
Walter S. Hulse, III	$ 6,076,450

Summary Compensation Table

(Footnotes Continued)

The amounts included for 2024 also relate to shares issued under our Employee Stock Award Program, pursuant to which we have issued one share of our

common stock to all eligible employees, including our named executive officers, for no monetary consideration, when the per-share closing price of our common

stock on the NYSE is at or above each one dollar increment above its previous high closing price. No shares were issued to eligible employees under this program

during 2022 or 2023. In 2024, we issued 26 shares to each employee under the program, including the named executive officers. The Employee Stock Award

Program terminated as of November 7, 2024, and no additional grants were made under the program after such date.

(2) The amounts for 2024 reflect the annual short-term cash incentive awards earned by each of the named executive officers in 2024 and paid in 2025. For a

discussion of the performance criteria established by the Committee for awards under the Annual Officer Incentive Plan, see “2024 Short-Term Incentive

Awards” above.

(3) The amounts in 2024 represent the aggregate change during 2024 in the actuarial present value of the named executive officers’ accumulated benefits under our

qualified Retirement Plan and our Supplemental Executive Retirement Plan. For a description of these plans, see “Pension Benefits” below. The change in the

present value of the accrued pension benefit is impacted by variables such as an increase in compensation, additional years of service, age and the applicable

discount rate, which for 2024 was 5.80% for the Retirement Plan and 5.80% for the Supplemental Executive Retirement Plan. The Retirement Plan was closed to

new participants in 2005, and the only named executive officer who participates in the plan is Mr. Swords. The change in net pension value for 2024 was an

increase of $336,265 for Mr. Swords. Mr. Swords is the only named executive officer who participates in our Supplemental Executive Retirement Plan. This plan

has not accepted any new participants since 2005.

(4) Reflects (i) the amounts paid as our dollar-for-dollar match of contributions made by the named executive officer plus quarterly and annual company profit-sharing

contributions to our 401(k) Plan, as well as non-matching employer contributions and corresponding excess contributions under our NQDC Plan, (ii) amounts paid

for annual holiday gifts, (iii) relocation expenses, (iv) personal use of company aircraft, and (v) charitable contributions made on behalf of the named executive

officer as follows with respect to 2024:

(a) For additional information on our NQDC Plan, see “Pension Benefits—Nonqualified Deferred Compensation Plan” below.

(b) Our 401(k) Plan is a tax-qualified plan that covers substantially all of our employees. Employee contributions are voluntary. Subject to certain limits, we

generally match 100% of employee contributions to the plan up to a maximum of 6% of eligible compensation. For a discussion of the matching contributions,

see "Retirement Benefits" at page 82 .

(c) The Profit Sharing Plan was merged into our 401(k) Plan effective January 1, 2019, and profit-sharing contributions are now made under our 401(k) Plan.

(d) This amount reflects the incremental costs incurred by our company for personal use of our corporate aircraft by Mr. Norton, Mr. Norton’s spouse, and Mr.

Hulse. The cost of personal use of our corporate aircraft is calculated based on the cost of fuel, crew travel, on-board catering, maintenance, landing fees and

trip-related hangar and parking costs and other similar variable costs. We divided the total variable costs by the total number of hours the aircraft flew to

determine an average variable cost per hour. The average variable cost per hour is multiplied by the hours flown for personal use to derive the incremental

cost. Fixed costs that do not change based on usage, such as pilot salaries, home hangar expenses and general taxes and insurance are excluded from the

incremental cost calculation. If our aircraft flies empty before picking up or after dropping off a passenger flying for personal reasons, the variable costs

associated with this “deadhead” segment are included in the incremental cost of the personal use

(e) Reflects charitable contributions made by our company or the ONEOK Foundation, Inc. on behalf of the named executive officer consisting of (i) matching

contributions up to $10,000 per year made to non-profit organizations of the officer’s choice under our employee matching grant program, and (ii) matching

contributions to the United Way pursuant to our annual United Way contribution program. The $25,000 contributions for Mr. Norton are matching contributions

to the Tulsa Area United Way.

(1) Reflects estimated payments that could be made under our Annual Officer Incentive Plan. The 2024 short-term incentive plan provides for awards based on financial and operational

performance of the company, as well as individual performance during the relevant fiscal year. Company performance and individual performance criteria are established annually by the

Committee. The Committee also establishes annual target and maximum awards for each officer expressed as a percentage of their base salaries. The actual amounts earned by the

named executive officers in 2024 under the plan and paid in 2025 are set forth under the “Non-Equity Incentive Plan Compensation” column in the Summary Compensation Table for

Fiscal 2024 above.

(2) Reflects the performance units that could be earned pursuant to awards granted under our 2018 EIP that will vest following the end of the applicable vesting period, at which time the

holder will be entitled to receive a percentage (0 to 200%) of the performance units granted based on our TSR over the performance period of January 1, 2024 - December 31, 2026,

compared with the TSR of the referenced peer group. One share of our common stock is payable in respect of each performance unit that vests. Performance units are also subject to

accelerated vesting upon a qualifying termination of employment in connection with a change in control as described under "2024 Long-Term Incentive Awards" at pages 88 - 89 .

(3) Reflects restricted units granted under our 2018 EIP that will vest at the end of a designated period, typically three years from the date of grant, at which time the grantee will be entitled to

receive the grant in shares of our common stock. Restricted units are also subject to accelerated vesting upon a qualifying termination of employment in connection with a change in

control as described under "2024 Long-Term Incentive Awards" at pages 88 - 89 .

(5) The amounts shown for the 2024 PSUs and RSUs reflect the grant date fair value of the awards ( with PSUs determined at payout percentage of target ) . The grant date fair value of the

2024 equity awards , assuming the highest level of performance (i.e. 200% of target for PSUs) are as follows: Mr. Norton, $16,557,519 , Mr. Hulse, $6,726,447 , Mr. Burdick, $3,725,367 ,

Mr. Swords, $3,725,367 , and Mr. Taylor, $3,828,985 The actual value, if any, that an executive may realize from a RSU or PSU award is contingent upon the satisfaction of the conditions

to vesting applicable to that award, and is determined by reference to stock price, which may fluctuate. Thus, there is no assurance that the value, if any, eventually realized by the

executive will correspond to the amount shown in the table.

(2) Represents performance units, including accrued dividend equivalents, that have not yet vested as of December 31, 2024. Performance units typically vest at the

end of a three-year vesting period, at which time the holder is entitled to receive a percentage (zero to 200%) of the performance units granted (and any accrued

dividend equivalent rights associated with such performance units) based on our cumulative TSR over the three-year performance period, compared with the

cumulative TSR of the referenced peer group. One share of our common stock is payable in respect of each performance unit granted that becomes vested. The

following table reflects the projected vesting level of our outstanding performance units at December 31, 2024, reflecting a 50% payout (the threshold payout under

the performance units) for grants vesting in 2025, and a 200% payout for grants vesting in 2026 and 2027.

(1) No new participants have been added to our Supplemental Executive Retirement Plan, a nonqualified defined benefit pension plan, since 2005, and, in

November 2013, our Board approved an amendment to the Supplemental Executive Retirement Plan that closed this plan to any additional participants as of

January 1, 2014. The Retirement Plan, a qualified defined benefit pension plan, was closed to new participants as of January 1, 2005. Mr. Swords is the only

named executive officer who participates in the Retirement Plan and the Supplemental Executive Retirement Plan.

(2) A participating executive officer’s benefit is determined as of age 62 when an unreduced benefit can be received under the plans. The present value of the

unreduced benefit is determined using the assumptions from the pension plan measurement date of December 31, 2024. Material assumptions used in the

calculation of the present value of accumulated benefits are included in Note M of the Notes to Consolidated Financial Statements included in our Annual Report

on Form 10-K for the year ended December 31, 2024.

Retirement Plan

The ONEOK, Inc. Retirement Plan ("Retirement Plan") is a defined benefit pension plan qualified under the Tax Code and is subject to the Employee

Retirement Income Security Act of 1974, as amended. At December 31, 2024, the plan covered eligible employees hired prior to January 1, 2005, or

in connection with an acquisition from Koch Industries on July 1, 2005. All other employees hired on or after January 1, 2005, and certain employees

who accepted a one-time opportunity to opt out of our Retirement Plan in 2004, participate in the profit-sharing feature in our 401(k) Plan.

Benefits under our Retirement Plan generally become vested and non-forfeitable after the completion of five years of continuous employment. Under

the plan, a vested participant receives a monthly retirement benefit beginning at the normal retirement age of 65, unless an early retirement benefit is

elected under the plan, in which case the retirement benefit may be actuarially reduced for early commencement. Generally, participants retiring on

or after age 62 through normal retirement age receive 100% of their accrued monthly benefit which may be reduced depending on the optional form

of payment elected at retirement. Accrued monthly benefits are calculated at the participant’s retirement date based on the participant’s credited

service, limited to a maximum of 35 years, multiplied by a percentage of their final average earnings. The earnings utilized in the Retirement Plan

benefit formula for employees include the base salary and short-term incentive compensation paid to an employee during the period of the

employee’s final average earnings, less any amounts deferred under our NQDC Plans. The period of final average earnings used to calculate the

accrued monthly benefit is the employee’s highest earnings during any 60 consecutive months during the last 120 months of employment. The

amount of eligible compensation that may be considered in calculating retirement benefits is also subject to limitations in the Tax Code.

Executive Compensation Discussion and Analysis

Supplemental Executive Retirement Plan

We maintain a Supplemental Executive Retirement Plan (“SERP”), a nonqualified supplemental retirement benefit plan for a select group of

management and highly compensated employees who also participate in our Retirement Plan. No new participants have been added to our SERP

since 2005, and the SERP has been closed to any additional participants since 2014.

The excess retirement benefit under the SERP pays a benefit equal to at least the benefit that would be payable to the participant under our

Retirement Plan, using the same formula as our Retirement Plan but as if limitations imposed by the Tax Code were not applicable and including

deferrals under our NQDC Plans in earnings, less the benefit payable under our Retirement Plan with such limitations. Although the SERP is an

unfunded arrangement for purposes of ERISA and the Tax Code, assets have been set aside in a rabbi trust to offset the associated SERP liabilities.

Nonqualified Deferred Compensation Plan

The following table sets forth certain information regarding the participation by the named executive officers in our NQDC Plans .

(1) The “All Other Compensation” column of the Summary Compensation Table for Fiscal Year 2024 at page 93 includes these amounts paid under our NQDC Plan

as our excess contributions, as well as quarterly and annual profit-sharing contributions with respect to our 401(k) Plan.

(2) There were no above-market earnings in 2024, 2023, or 2022.

(3) Of the total amounts shown in each NEO’s Aggregate Balance at Last Fiscal Year End, the following amounts have been reported as “Salary,” “Bonus,” “Non-

Equity Incentive Plan Compensation,” or “All Other Compensation” in the Summary Compensation Table (in 2024 and in previous years) for Mr. Norton: $827,345 ;

Mr. Hulse: $1,807,713 ; Mr. Burdick: $1,175,655 ; Mr. Swords: $466,412 ; and Mr. Taylor: $143,825 .

We maintain the NQDC Plan to provide a select group of management and highly compensated employees with the option to defer portions of their

cash compensation and provide notional employer contributions that are not otherwise available due to limitations on employer and employee

contributions to qualified defined contribution plans under the federal tax laws. In 2024, we made notional contributions to the NQDC Plan in the

amount of 6% of eligible compensation above the applicable federal tax limit to all NQDC Plan participants, plus an additional 7% of eligible

compensation above the applicable federal tax limit for NQDC Plan participants who do not participate in the SERP .

The NQDC Plan also allows for supplemental credit amounts, which are amounts that can be contributed at the discretion of the Committee. No such

supplemental credits were contributed in 2024. The participant, at the time a deferral election is made, must specify the distribution date for such

deferrals, which may be a date specified by the participant or the date of the participant's separation from service. Deferred amounts may also be

distributed upon the participant’s death or disability, or upon change in control.

100 2025 ONEOK, Inc. Proxy Statement

Executive Compensation Discussion and Analysis

Short-term deferral accounts were available for amounts deferred prior to 2020 and are credited with a notional investment return based on the five-

year United States Treasury bond rate as of the first business day of January each year, which was 3.93% for 202 4. All other deferrals and company

contributions deferred and earned prior to 2020 , and all amounts contributed under the NQDC Plan, are credited with a notional investment return

based on the amount of gains, losses and earnings for each of the investment options selected by the participant. For the year ended December 31,

2024, the notional investment return for the investment options were as follows:

(1) Fund inception date - June 28, 2022.

At the distribution date, cash is distributed to participants based on the fair market value of the deemed investment of the participant’s accounts at

that date. Although the NQDC Plans are unfunded arrangements for purposes of ERISA and the Tax Code, assets have been set aside in a rabbi

trust to offset the associated NQDC Plans' liabilities . Amounts may no longer be deferred under the Prior NQDC Plans but do continue to accrue

notional interest and remain subject to the terms of those plans and participant elections as to the timing of distributions.

POTENTIAL POST-EMPLOYMENT PAYMENTS

AND PAYMENTS UPON A CHANGE IN CONTROL

Described below are the post-employment compensation and benefits that we provide to our named executive officers. The objectives of the

post-employment compensation and benefits that we provide are to:

• Assist in recruiting and retaining talented executives in a competitive market;

• Provide security for any compensation or benefits that have been earned;

2025 ONEOK, Inc. Proxy Statement 101

Executive Compensation Discussion and Analysis

• Permit executives to focus on our business;

• Eliminate any potential personal bias of an executive against a transaction that is in the best interest of our shareholders;

• Avoid the costs associated with separately negotiating executive severance benefits; and

• Provide us with the flexibility needed to react to a continually changing business environment.

We do not enter into individual employment agreements with our named executive officers . Instead, in general, the rights of our executives with

respect to specific events are covered by our compensation and benefit plans. Under this approach, post-employment compensation and benefits

are established separately from the other elements of our executives' compensation.

The use of a “plan approach” instead of individual employment agreements serves several objectives. First, the plan approach provides us with more

flexibility to change the terms of severance benefits from time to time if necessary. Second, the plan approach is more transparent, both internally

and externally. Internal transparency eliminates the need to negotiate separation benefits on a case-by-case basis and assures an executive that his

or her severance benefits are comparable with those of his or her peers. Finally, the plan approach is easier for us to administer, as it requires less

time and expense.

Payments Made Upon Any Termination

Regardless of the manner in which a named executive officer’s employment terminates, he or she is entitled to receive amounts earned during his or

her term of employment. These amounts include:

• Accrued but unpaid salary;

• Amounts contributed under our 401(k) Plan and the NQDC Plans;

• Amounts accrued and vested through our Retirement Plan and SERP; and

• The value of unused prorated vacation benefits (except in the case of death, in which case unused vacation is paid in full, or if required by state law).

Payments Made Upon Termination Without Cause,

Disability or Retirement

In the event of the termination without cause of a named executive officer, in addition to the items identified above, such named executive officer will

be entitled to:

• Receive a prorated portion of each outstanding restricted unit award; and

• If hired prior to January 1, 2017, participate in retiree health and life benefits for eligible participants and qualifying dependents.

In the event of the termination upon disability or retirement of a named executive officer, in addition to the items identified above, such named

executive officer will be entitled to:

• Receive a prorated portion of each outstanding performance unit award upon completion of the applicable performance periods; and

• Receive a prorated payout under the Annual Officer Incentive Plan.

Payments of deferred compensation to a “specified employee ” upon a “separation from service” within the meaning of Section 409A of the Tax Code

are subject to a six-month delay on payment.

Payments Made Upon Death

In the event of the death of a named executive officer, in addition to the benefits listed under the headings “Payments Made Upon Any Termination”

and “Payments Made Upon Termination without Cause, Disability or Retirement” above, the named executive officer’s beneficiary(ies) will receive

applicable payments under our life insurance plan and accidental death and dismemberment plan , if eligible.

102 2025 ONEOK, Inc. Proxy Statement

Executive Compensation Discussion and Analysis

Payments Made Upon or Following a Change in Control

We believe that the possibility of a change in control creates uncertainty for executive officers because such transactions frequently result in changes

in senior management. Our Board has adopted a Change in Control Severance Plan that covers all of our executive officers, including the named

executive officers. Subject to certain exceptions, the Change in Control Severance Plan will provide our officers with severance benefits if they are

terminated by us without cause (as defined in the Change in Control Severance Plan and discussed in greater detail below) or if they resign for good

reason (as defined in the Change in Control Severance Plan), in each case within two years following a change in control of the company. All

Change in Control Severance Plan benefits are “double trigger,” meaning that payments and benefits under the plan are payable only if the officer’s

employment is terminated by us without “cause” or by the officer for a “good reason” at any time during the two years following a change in control.

Severance payments under the plan consist of a single lump sum cash payment that may be up to three times the participant’s base salary and

target short-term incentive bonus, plus reimbursement of COBRA healthcare premiums for up to 18 months. Our Board, upon the recommendation of

the Committee, established a severance multiplier of two times the sum of the annual salary plus the target short-term incentive for each of our

named executive officers except for Mr. Norton, whose multiplier is three times.

The Change in Control Severance Plan does not provide for additional pension benefits upon a change in control. Severance payments and benefits

under the Change in Control Severance Plan will be reduced if, as a result of such reduction, the officer would receive a greater total payment after

taking taxes, including excise taxes, into account.

Relative to the overall value of our company, we believe the potential benefits payable upon a change in control under the Change in Control

Severance Plan are comparatively minor, and we believe that the level of benefits is consistent with the general practice among our peers.

For the purposes of the Change in Control Severance Plan, a “change in control” generally means any of the following events:

• An acquisition of our voting securities by any person that results in the person having beneficial ownership of 20% or more of the combined voting

power of our outstanding voting securities, other than an acquisition directly from us;

• The current members of our Board, and any new director approved by a vote of at least two-thirds of our Board, cease for any reason to

constitute at least a majority of our Board, other than in connection with an actual or threatened proxy contest (collectively, the

“Incumbent Board”);

• A merger, consolidation or reorganization with us or in which we issue securities, unless (i) our shareholders immediately before the transaction,

as a result of the transaction, own, directly or indirectly, at least 50% of the combined voting power of the voting securities of the company

resulting from the transaction, (ii) the members of our Incumbent Board after the execution of the transaction agreement constitute at least a

majority of the members of the Board of the company resulting from the transaction, or (iii) no person other than persons who, immediately before

the transaction owned 20% or more of our outstanding voting securities, has beneficial ownership of 20% or more of the outstanding voting

securities of the company resulting from the transaction; or

• Our complete liquidation or dissolution or the sale or other disposition of all or substantially all of our assets.

For the purposes of the Change in Control Severance Plan, termination for “cause” means a termination of employment of a participant in the

Change in Control Severance Plan by reason of:

• A participant’s indictment for or conviction in a court of law of a felony or of any crime or offense involving misuse or misappropriation of money

or property;

• A participant’s violation of any covenant, agreement or obligation not to disclose confidential information regarding the business of the company

(or a division or subsidiary) or a participant’s violation of any covenant, agreement or obligation not to compete with the company (or a division

or subsidiary);

• Any act of dishonesty by a participant that adversely affects the business of the company (or a division or subsidiary) or any willful or intentional

act of a participant that adversely affects the business, or reflects unfavorably on the reputation, of the company (or a division or subsidiary);

• A participant’s material violation of any written policy of the company (or a division or subsidiary); or

• A participant’s failure or refusal to perform the specific directives of the Board or its officers, which are consistent with the scope and nature of the

participant’s duties and responsibilities, to be determined in the Board’s sole discretion.

For the purposes of the Change in Control Severance Plan, “good reason” means:

• A participant’s demotion or material reduction of the participant’s significant authority or responsibility with respect to employment with the

company from that in effect on the date the change in control occurred;

• A material reduction in the participant’s base salary from that in effect immediately prior to the change in control;

2025 ONEOK, Inc. Proxy Statement 103

Executive Compensation Discussion and Analysis

• A material reduction in short-term and/or long-term incentive targets from those applicable to the participant immediately prior to the change

in control;

• The company's relocation of the participant to a new principal place of employment that is more than 35 miles further from the participant's

principal place of residence than the participant’s principal place of employment prior to such change; and

• The failure of a successor company to explicitly assume the Change in Control Severance Plan.

Post-Employment Payments Tables

The following tables reflect estimates of the incremental amount of compensation due to each named executive officer in the event of such

executive’s termination of employment by reason of death, disability or retirement, termination of employment without cause, or termination of

employment without cause or with good reason within two years following a change in control. The amounts shown assume termination effective as

of December 31, 2024 and are estimates of the amounts that would be paid to the executives upon such termination, including, with respect to

performance units, the performance factor calculated as if the performance period ended on December 31, 2024. The amounts reflected in the

“Qualifying Termination Following a Change in Control” column of the tables that follow are the amounts that would be paid pursuant to our Change

in Control Severance Plan and, with respect to outstanding performance units, assume a qualifying change in control and termination of employment

effective December 31, 2024 and the greater of (i) vesting at the target level, prorated for the elapsed portion of the vesting period through the date

of the change in control, or (ii) vesting using a performance factor based on our total shareholder return relative to the designated peer group on that

date without any proration, in either case taking into account the effect of dividend equivalents. The value of restricted units and performance units

reflected in the tables below is based on the closing price of our stock on the NYSE on December 31, 2024 of $100.40 .

would decrease from $466,960 to zero; performance units would decrease from $676,094 to zero; total equity would decrease from $1,143,054 to zero; and total

payout would decrease from $1,752,687 to $ 609,633 . In addition, Mr. Taylor's cash severance would decrease from $569,300 to zero.

2024 CEO PAY RATIO

Securities and Exchange Commission rules implementing the Dodd-Frank Act require public companies to disclose the ratio of CEO annual total

compensation to median employee annual total compensation. Using the methodology described below, (i) the annual total compensation for our

CEO in 2024 was $13,237,333 (ii) the annual total compensation for our median employee in 2024 was $ 158,449 ; and (iii) the resulting ratio of our

CEO’s compensation to median employee compensation in 2024 was 84 to one.

The median employee for 2024 was determined by ranking the gross salary of all active employees, excluding our CEO, as of December 31, 2024.

As permitted by Securities and Exchange Commission Item 402(u) of Regulation S-K, we excluded the 165 legacy Medallion employees hired in

connection with our acquisition of Medallion in October 2024 from the employee population for purposes of the CEO pay ratio calculation for 2024.

The 1,063 EnLink employees hired in connection with our acquisition of EnLink were not included as part of the CEO pay ratio calculation for 2024 as

that acquisition closed in January 2025.

We calculated annual total compensation for the median employee in 2024 according to the same methodology used to calculate total compensation

for our CEO in the Summary Compensation Table.

We believe the foregoing pay ratio disclosure, including but not limited to any assumptions, estimates, adjustments, methodologies and existing

internal records used to identify our median employee, is a reasonable estimate calculated in a manner consistent with Securities and Exchange

Commission Item 402(u) of Regulation S-K. The Securities and Exchange Commission rules for identifying the median employee and calculating the

ratio of our CEO annual total compensation to that employee’s annual total compensation allow companies to make reasonable assumptions and

estimates, and to apply a variety of methodologies and exclusions that reflect their compensation practices. As a result, the pay ratio reported by

other companies may not be comparable to the pay ratio reported above, as other companies may have different compensation practices, and may

utilize different assumptions, estimates, methodologies and exclusions in calculating their own pay ratios.

2025 ONEOK, Inc. Proxy Statement 105

Approval of the ONEOK, Inc. 2025 Equity Incentive Plan
●	Our Board unanimously recommends a vote FOR the approval of the ONEOK, Inc. 2025 Equity Incentive Plan.

INTRODUCTION

We are asking shareholders to approve the ONEOK, Inc. 2025 Equity Incentive Plan (the “2025 EIP”). Our Board approved the 2025 EIP on

February 19, 2025 upon the recommendation of the Executive Compensation Committee and subject to shareholder approval at the 2025 annual

meeting. If approved by a majority of the voting power of shareholders present online or by proxy and entitled to vote upon the proposal and at the

2025 annual meeting , the 2025 EIP will become effective as of the date of the shareholder approval (the “2025 EIP Effective Date”).

A copy of the 2025 EIP is attached to this proxy statement as Appendix A.

Subject to shareholder approval of the 2025 EIP, the 2025 EIP will replace the ONEOK, Inc. 2018 Equity Incentive Plan, effective as of May 23, 2018

and subsequently amended as of November 8, 2023 (the “2018 EIP”) and no additional awards will be granted under the 2018 EIP on or after the

2025 EIP Effective Date. Outstanding awards under the 2018 EIP as of the 2025 EIP Effective Date, including any deferred awards, will remain in

effect in accordance with the terms of the 2018 EIP and any applicable award agreement, and if applicable, deferred compensation plan.

The 2025 EIP will allow us to continue granting long-term equity incentive awards to employees and equity awards to our non-employee directors.

Eligible participants under the 2025 EIP are comprised of our non-employee directors and employees of ours and our subsidiaries who are

executives and senior management, and other employees who are responsible for our day-to-day operations. As of March 1, 2025, the approximate

aggregate number of employees and non-employee directors who would have been eligible for awards under the 2025 EIP if the 2025 EIP was in

effect as of such date is 6,309. As of March 1, 2025, the approximate number of persons in each eligible class under the 2025 EIP is as follows:

6,300 employees (including 68 executive officers) and 9 non-employee directors. As non-employee directors and executive officers are eligible to

participate in the 2025 EIP, each member of the Board and each executive officer has an interest in this proposal.

The closing price of a share of our common stock on February 28, 2025 (the last trading day prior to March 1, 2025) was $100.39.

The 2025 EIP will not be effective unless approved by the shareholders. If the 2025 EIP is not approved by the shareholders, we will be limited in our

ability to grant further long-term equity incentive awards to employees or equity awards to our non-employee directors, because we will not have

sufficient shares reserved for issuance under the 2018 EIP and the NYSE rules generally require shareholder approval to increase the share reserve

under an equity compensation plan. The alternative to using equity awards for retention and incentive purposes would be to increase cash

compensation. We do not believe that increasing cash compensation to make up for any shortfall in equity awards would be practicable, advisable or

in the best interests of our shareholders. We believe that a combination of equity awards and cash compensation provides a more effective

compensation vehicle than cash alone for attracting, retaining and motivating employees and aligning employee and shareholder interests.

Accordingly, shareholder approval of the 2025 EIP is important in order to enable us to continue to retain and attract the most qualified talent in the

industry and to ensure our employees’ interests are aligned with those of our shareholders.

PROPOSAL 3: Approval of the ONEOK, Inc. 2025 Equity Incentive Plan

IMPORTANT GOVERNANCE FEATURES

AND PRACTICES

The 2025 EIP includes numerous provisions that the Executive Compensation Committee and Board believe promote best practices by reinforcing

the alignment between equity compensation arrangements for non-employee directors, officers, and other employees and shareholders’ interests.

Those provisions include, but are not limited to, the following:

Feature/Practice	Description
No Discounted Options or Stock Appreciation Rights (“SARs”)	Stock options and SARs may not be granted with an exercise price lower than the market value of the underlying shares on the grant date.
No Repricing or Cash Buyouts Without Shareholder Approval	The purchase price of an option or SAR may not be reduced without shareholder approval, and underwater options or SARs may not be exchanged, surrendered, or cancelled and regranted for awards with a lower exercise price or cash without shareholder approval, except in connection with a change in our capitalization.
No Liberal Share Recycling	We do not allow the reuse for future awards of shares used to pay the exercise price or withholding taxes for an outstanding award, unissued shares resulting from the net settlement of an outstanding option or SAR, or shares purchased in the open market using proceeds of an option exercise.
Double Trigger Change in Control Vesting	In general, a change in control will not automatically trigger vesting unless the successor does not assume or replace the outstanding awards. Rather, participants must experience a termination of employment without cause or resign for good reason within two years following a change in control for an award to vest in connection with a change in control. The Executive Compensation Committee, however, retains discretion to provide otherwise in an award agreement or before a change in control.
Clawback; Recoupment	Awards, including time-based restricted unit and performance-vesting unit awards, will be subject to our clawback or recoupment policies as in effect from time to time, whether approved before or after the date awards are granted. See “Clawback Policy” above at page 90 .
No Dividends on Unvested Awards	If dividend equivalents are credited or payable in connection with an award, the dividend equivalents must be subject to the same restrictions and risk of forfeiture as the underlying award and may not be paid unless the underlying award vests.
Individual Limits on Non-Employee Director Awards	The 2025 EIP imposes a limit on the value of the shares that we may grant to a non-employee director, together with any cash fees paid to the non-employee director, in a year.
No Tax Gross-Ups	The 2025 EIP does not provide for any tax gross-ups.
Material Amendments Require Shareholder Approval	We must obtain shareholder approval for material plan changes, including increasing the number of shares authorized for issuance, materially modifying participation requirements, and changing the restrictions on repricing.
Independent Administration	The 2025 EIP is administered by the Executive Compensation Committee, which is composed entirely of “independent directors” within the meaning of NYSE requirements and “non-employee directors” as defined in Rule 16b-3 under the Securities Exchange Act of 1934 (the “Exchange Act”).
No Evergreen Provision	The 2025 EIP does not contain an “evergreen” feature that automatically replenishes the shares available for future grants under the 2025 EIP.
No Automatic Grants or Reload Grants	The 2025 EIP does not provide for “reload” or other automatic grants to any participant.

2025 ONEOK, Inc. Proxy Statement 107

PROPOSAL 3: Approval of the ONEOK, Inc. 2025 Equity Incentive Plan

SHARES TO BE AUTHORIZED UNDER THE PLAN

Subject to adjustment as described below, upon approval of the 2025 EIP, the aggregate number of shares of our common stock that may be issued

or delivered under the 2025 EIP will not exceed 16,870,000 newly-authorized shares of our common stock, plus 2,279,829 shares of our common

stock, which is the number of shares reserved for issuance under the 2018 EIP that remained available for awards under the 2018 EIP as of March

1, 2025 and which shall be reduced by the number of shares underlying any grants made under the 2018 EIP after March 1, 2025 and before the

2025 EIP Effective Date. In addition, any shares of our common stock that are subject to outstanding awards under the 2018 EIP and that, following

the 2025 EIP Effective Date, expire, or are terminated, surrendered or forfeited for any reason without issuance of such shares, or are settled in

cash, will become available for new awards under the 2025 EIP, subject to adjustment as described below.

We believe that approval of the 2025 EIP, including the number of shares requested, will give us flexibility to continue to make stock-based grants

and other awards for approximately ten years in amounts determined appropriate by the Executive Compensation Committee, based on our historical

share grant utilization practices. This time period is an estimate. The actual rate at which we use shares under the 2025 EIP may be more or less

than our anticipated future usage and will depend upon various unknown factors, such as our future stock price, plan participation levels, hiring and

promotion activity, award mix , competitive market practices, acquisitions and divestitures, and rates of forfeiture. These changes could affect the time

period the requested number of authorized shares are expected to last.

In recommending to the Board the number of shares to be reserved for issuance under the 2025 EIP, the Executive Compensation Committee

considered our historical grant practices, current and historical grant levels, projected duration of share pool levels at different share prices, proxy

advisory firm policies and anticipated shareholder reaction. The Executive Compensation Committee and the Board also considered the advice of

Meridian Compensation Partners, the Executive Compensation Committee’s independent compensation consultant.

Dilution Analysis

In addition to the adoption of the 2025 EIP, the Board is recommending that our shareholders approve the adoption of the ONEOK, Inc. 2025

Employee Stock Award Program (the “2025 ESAP") as set forth in Proposal No. 4. If approved by our shareholders, 700,000 shares will be

authorized for issuance under the 2025 ESAP, subject to adjustment as provided in the 2025 ESAP. The ONEOK Employee Stock Award Program

(the "Prior ESAP") terminated on November 7, 2024 and has no shares available for issuance.

In connection with the acquisition of EnLink , we converted outstanding restricted incentive units and performance units issued under the EnLink

Midstream, LLC 2014 Long-Term Incentive Plan (the “EnLink LTIP”) into time-based restricted units with respect to our common stock, and we

assumed the EnLink LTIP with respect to these awards. No awards will be made under the EnLink LTIP on or after January 31, 2025, the closing date

of the acquisition transaction. The converted awards represented 480,280 shares of our common stock as of January 31, 2025. Shares underlying

these awards will be issued under the assumed EnLink LTIP and not under the 2018 EIP or the 2025 EIP (if adopted), and any shares with respect to

forfeited or terminated awards under the EnLink LTIP will not be added to the share reserve of the 2018 EIP or the 2025 EIP (if adopted).

As of March 1, 2025, we had 624,640,751 shares of our common stock outstanding, 4,083,074 shares of our common stock were subject to

outstanding awards under the 2018 EIP and other equity plans (counting performance units at maximum performance) , other than our Employee

Stock Purchase Plan, and 2,279,829 shares of our common stock were available for future awards under the 2018 EIP (counting performance units

at maximum performance) . The potential dilution resulting from issuing the outstanding awards and shares remaining available for issuance under

the 2018 EIP would be approximately 1.0%, on a fully-diluted basis using our common stock outstanding as of March 1, 2025. If the proposed

16,870,000 newly-authorized shares of our common stock are made available for issuance under the 2025 EIP, the potential dilution will increase by

2.6 percentage points and the fully-diluted total potential dilution would approximate 3.6% as of March 1, 2025 . If both the 2025 EIP and the 2025

ESAP had been in effect on March 1, 2025 with 16,870,000 newly-authorized shares and 700,000 newly-authorized shares, respectively, reserved

for issuance, the fully-diluted total potential dilution associated with the equity plans as of March 1, 2025 would have been 3.7%.

Burn Rate

In connection with our stock-based compensation programs, we are committed to using equity incentive awards prudently and within reasonable

limits. Accordingly, we closely monitor our share usage (referred to as “burn rate”) each year and over the long-term. The table below sets forth the

following information regarding the awards granted under our equity plans (the 2018 EIP and Prior ESAP (as defined below)): (i) the burn rate for

each of the last three calendar years and (ii) the average burn rate over the last three calendar years. The burn rate for a year has been calculated

as follows: (a) all full value awards granted in the applicable year (including time-based and performance-based), divided by (b) the weighted-

average number of shares of common stock outstanding for the applicable year.

We did not make any option or SAR grants during the last three calendar years .

108 2025 ONEOK, Inc. Proxy Statement

PROPOSAL 3: Approval of the ONEOK, Inc. 2025 Equity Incentive Plan

We have included in the table below a burn rate calculation based on the number of time-based restricted stock unit awards and performance-based

stock units granted in the applicable year (counting performance units at target performance), divided by the weighted-average basic shares of

common stock outstanding for the applicable year. The numbers reported in the table below do not include shares that relate to equity awards that

we assumed in connection with our acquisition of Magellan on September 25, 2023. The numbers reported in the table also do not include equity

awards that we assumed in connection with our acquisition of EnLink on January 31, 2025 or shares purchased under our Employee Stock Purchase

Plan.

Burn Rate — Element	2024	2023	2022	Average
Total Number of Full Value Awards	964,787	689,850	722,363	792,333
Total Number of Time-Based Full Value Awards Granted	512,427	320,628	323,048	385,368
Total Number of Performance-Based Full Value Awards Granted	452,360	369,222	399,315	406,966
Weighted Average Basic Shares of Common Stock Outstanding	584,600,000	484,300,000	447,500,000	505,466,667
Burn Rate	0.17%	0.14%	0.16%	0.16%

The burn rate means that we used an annual average of 0.16% of the weighted average shares of our common stock outstanding for awards granted

or earned over the past three years.

Updated Share Information as of March 1, 2025

The information included in this proxy statement and our 2024 annual report is updated by the following information regarding the existing equity

compensation plans, other than our Employee Stock Purchase Plan, as of March 1, 2025 (except as otherwise noted):

Total number of full value awards outstanding (includes restricted stock units, performance units, and deferred director stock awards) (1) (2)	4,083,074
Shares available for grant under the 2018 EIP (3)	2,279,829
New Shares Requested under the 2025 EIP (2)	16,870,000
Total Shares Reserved under the 2025 EIP Upon Shareholder Approval (2)	19,149,829
Total shares of common stock outstanding as of March 1, 2025	624,640,751

(1) No stock options or SARs were outstanding as of March 1, 2025.

(2) The total number of full value awards outstanding includes shares issued in connection with the Magellan and EnLink acquisitions. The number of shares of

outstanding performance unit awards assumes performance at the maximum performance level. Any award granted from the 2018 EIP between March 1, 2025

and the effective date of the 2025 EIP will reduce the number of shares available under the 2025 EIP by one share for each share underlying each award granted.

(3) The 2018 EIP is our only active employee equity incentive plan with shares remaining available for future grants, other than our Employee Stock Purchase Plan.

The number of shares remaining available for future grants under the 2018 EIP reflects performance unit awards at maximum payout. Our Prior ESAP terminated

on November 7, 2024.

SUMMARY OF THE PLAN

The following is a summary of the material features of the 2025 EIP. This summary, however, is not intended to be a complete description of all the

provisions of the 2025 EIP and is qualified in its entirety by the full text of the 2025 EIP, a copy of which is attached to this proxy statement as

Appendix A.

Purposes: The purposes of the 2025 EIP are to attract, retain, motivate and reward our non-employee directors, officers and employees and the

officers and employees of our subsidiaries , to compensate them for their contributions to the growth and profitability of the company, to encourage

their ownership of our common stock of in order to align their interests with those of the shareholders, and to promote our sustained long-term

performance and the creation of shareholder value.

2025 ONEOK, Inc. Proxy Statement 109

PROPOSAL 3: Approval of the ONEOK, Inc. 2025 Equity Incentive Plan

Plan Term: The 2025 EIP will be effective on the 2025 EIP Effective Date and will terminate on the day immediately before the tenth anniversary of

the 2025 EIP Effective Date, unless terminated earlier by the Board.

Eligibility: All of our non-employee directors, officers and employees and the officers and employees of our subsidiaries are eligible to be selected to

receive awards under the 2025 EIP. Non-employee directors are not eligible to receive incentive stock options, performance units or performance shares.

Administration: The 2025 EIP will be administered by the Executive Compensation Committee. The Executive Compensation Committee is

composed solely of directors who are: (i) “non-employee directors” as defined in Rule 16b-3 under the Exchange Act; and (ii) “independent directors”

within the meaning of the NYSE requirements.

The Executive Compensation Committee’s discretionary authority will include the power, subject to the terms and limitations expressly provided in

the 2025 EIP: to grant awards; determine the size and types of awards; establish terms and conditions for each award; accelerate the exercisability

or vesting of all or part of any award; interpret the 2025 EIP and any agreement or instrument entered into pursuant to the 2025 EIP; establish,

amend or waive the 2025 EIP administration rules; amend the terms and conditions of any outstanding award; delay issuance of common stock or

suspend a participant’s right to exercise an award to comply with applicable laws; determine the duration and purposes of leaves of absence that

may be granted to a participant without constituting termination of his or her employment or service for 2025 EIP purposes; authorize any person to

execute, on our behalf, any instrument required to carry out the 2025 EIP’s purposes; correct any defect or omission, or reconcile any inconsistency

in the 2025 EIP or any award; make determinations that it deems necessary or advisable for the 2025 EIP administration; and address participants’

claims, including resolving disputed issues of fact.

The 2025 EIP will permit the Executive Compensation Committee, in its sole discretion, to delegate any or all of its authority to administer the 2025

EIP to our Benefit Plan Administration Committee or our chief executive officer; provided, however, that (i) any delegation will be permitted only to the

extent permissible under NYSE rules and applicable securities and other laws, and (ii) the Executive Compensation Committee will not delegate the

authority to grant awards to individuals subject to Section 16 of the Securities Exchange Act of 1934, as amended .

Shares Authorized: Subject to adjustment as described below, upon approval of the 2025 EIP, the aggregate number of shares of our common

stock that may be issued or delivered under the 2025 EIP will not exceed 16,870,000 newly-authorized shares of our common stock, plus 2,279,829

shares of our common stock, which is the number of shares reserved for issuance under the 2018 EIP that remained available for awards under the

2018 EIP as of March 1, 2025 and which shall be reduced by the number of shares underlying any grants made under the 2018 EIP after March 1,

2025 and before the 2025 EIP Effective Date. In addition, any shares of our common stock that are subject to outstanding awards under the 2018

EIP and that expire, or are terminated, surrendered or forfeited following the 2025 EIP Effective Date for any reason without issuance of such shares,

or are settled in cash, will become available for new awards under the 2025 EIP, subject to adjustment as described below.

Shares of our common stock may be issued under the 2025 EIP from our authorized but unissued shares, treasury shares, shares we purchase on

the open market, or any combination of the above.

Share Counting: If an award granted under the 2025 EIP or under the 2018 EIP is cancelled or forfeited, expires, terminates or is settled in cash,

the shares underlying such award will again be available under the 2025 EIP. The following shares underlying awards granted under the 2025 EIP

will not again be available: (i) shares that are not issued upon the net settlement of stock-settled SARs or the net exercise of an option; (ii) shares

that are delivered to or withheld by us to pay the exercise price or the withholding taxes due with respect to an option or SAR; (iii) shares that are

delivered to or withheld by us to pay withholding taxes related to awards other than options and SARs; and (iv) shares that are purchased on the

open market with the proceeds of an option exercise.

Grant of Awards: The 2025 EIP will provide for awards in the form of restricted stock units (“RSUs”), restricted stock awards, performance units,

performance shares, nonqualified and incentive options (“NQSOs” and “ISOs” respectively), SARs, other awards and director stock awards. Award

agreements provided with respect to any award under the 2025 EIP will describe the specific terms of the award, including vesting schedules and

applicable performance goals, if any. The following is a brief description of the various types of awards that may be issued under the 2025 EIP:

• RSUs and Restricted Stock: RSUs represent the future right to receive common stock, an equivalent cash value, or a combination of common

stock and cash. A restricted stock award represents a current award of common stock. Each RSU or restricted stock award will be subject to

certain restrictions and risk of forfeiture according to terms set by the Executive Compensation Committee in the award agreement. The

Executive Compensation Committee may permit a participant to defer delivery of common stock related to an RSU so long as such deferral is

pursuant to a deferred compensation plan offered by us and that satisfies the requirements of Section 409A of the Tax Code.

• Performance Shares and Performance Units: Performance shares and performance units represent the future right to earn common stock, an

equivalent cash value, or a combination of common stock and cash based on achieving performance goals over a specified performance period,

both as set by the Executive Compensation Committee in the award agreement. The actual number of shares participants receive may be more or

less than the specified target number of shares depending on the achievement of the performance goals during the performance period. The

Executive Compensation Committee may permit a participant to defer delivery of common stock related to a performance share or performance unit

so long as such deferral is pursuant to a deferred compensation plan offered by us and satisfies the requirements of Section 409A of the Tax Code.

PROPOSAL 3: Approval of the ONEOK, Inc. 2025 Equity Incentive Plan

• Stock Options and Stock Appreciation Rights: An option is the right to purchase common stock at a specified price during a specified time

period. The Executive Compensation Committee may grant either ISOs or NQSOs. A SAR entitles the participant to receive an amount equal to

the excess, if any, of the fair market value of one share of common stock on the date of exercise over the base price of the SAR. The exercise

price of an option or the base price of a SAR may not be less than the fair market value of the common stock on the grant date. At the discretion

of the Executive Compensation Committee, payment upon the exercise of a SAR may be in cash, in shares of common stock of equivalent value,

or in a combination thereof. Option and SAR awards will have a maximum term of ten years. Each option and SAR granted under the 2025 EIP

will become exercisable in accordance with the specific terms and conditions of the award agreement, as determined by the Executive

Compensation Committee.

• Other Awards: The Executive Compensation Committee may grant other awards not described above that may be payable in cash or shares of

common stock, based in whole or in part on the value of our common stock. The Executive Compensation Committee may also grant shares as a

bonus and grant other awards in lieu of obligations under other company compensation arrangements, including cash payments based on

attaining performance goals or other criteria. Other awards may include dividend equivalents that are converted into shares of our common stock

in connection with awards granted under the 2025 EIP or our other equity plans. The terms and conditions applicable to such other awards will be

determined by the Executive Compensation Committee and set forth in an award agreement.

• Director Stock Awards: Non-employee directors receive a portion of their annual director fees in shares of our common stock. The remainder of

the annual director fees are payable in cash or in shares as elected by the non-employee director. If a non-employee director elects to receive

some or all of the director’s annual cash retainer in shares, the shares received will be treated as a director stock award and will count against the

2025 EIP overall share limit. The number of shares to be paid and distributed to a non-employee director as a director stock award will be

determined by dividing the dollar amount of the director fees to be paid in shares (which the Board has established and/or the non-employee

director has elected) by the market value of a share on the payment date.

Substitute Awards: The 2025 EIP will permit the Executive Compensation Committee to grant awards in substitution for any award previously

granted by a company or other entity in connection with a corporate transaction, such as a merger or consolidation with another entity or acquisition

of property or stock of another entity. Substitute awards will not count against the 2025 EIP overall share limit or any other limit in the 2025 EIP.

Substitute awards that are options or SARs may have an exercise price that is less than the fair market value of a share on the date of substitution if

such substitution complies with the requirements of Section 409A of the Tax Code, NYSE rules, and other applicable laws.

Dividend Equivalents: The recipient of an award (other than options and SARs) may be entitled to receive dividend equivalents, provided that the

dividend equivalents will become payable only if and to the extent the underlying award vests, regardless of whether vesting is contingent upon

continued employment, the achievement of performance goals, or both.

Performance-Based Awards: The 2025 EIP will permit the Executive Compensation Committee to grant awards of either common stock or cash

that become payable only upon the achievement of performance goals. The performance goals will be determined by the Executive Compensation

Committee and set forth in the award agreement.

Performance goals for any such awards may be based on one or more performance objectives, including but not limited to the following: earnings,

earnings growth, earnings per share, stock price (including growth measures and total shareholder return), improvement of financial ratings, internal

rate of return, market share, cash flow, operating income, operating margin, net profit after tax, EBIT, EBITA, EBITDA, OBIT, OBITDA, gross profit,

operating profit, cash generation, revenues, asset quality, return on equity, return on tangible common equity, return on assets, return on operating

assets, cost saving levels, efficiency ratio, net income, marketing-spending efficiency, core non-interest income, change in working capital, return on

capital, shareholder return or strategic goals and objectives, including objectives related to qualitative or quantitative environmental, social and

governance metrics, e.g., AREER, TRIR. Performance goals need not be based upon an increase or positive result under a particular business

criterion and could include, for example, maintaining the status quo or limiting economic losses (measured, in each case, by reference to specific

business criteria).

The performance goals may be described in terms of objectives that are related to the individual participant or objectives that are companywide or

related to a subsidiary, business unit, division, segment, work location, geographic region, product line, or function or any combination thereof.

Performance goals may be measured on an absolute or cumulative basis or on the basis of percentage of improvement over time. Further,

performance goals may be measured in terms of company performance (or performance of the applicable subsidiary, business unit, division,

segment, work location, geographic region, product line, function, or combination thereof) or measured relative to a market index, selected peer

companies or one or more operating units, divisions, acquired businesses, minority investments, partnerships or joint ventures.

Each performance-based award will be earned, vested and payable only upon the Executive Compensation Committee’s certification of the

achievement of the performance goals set forth in the award agreement, along with the satisfaction of any other term or condition, such as continued

employment, as the Executive Compensation Committee deems appropriate. The Executive Compensation Committee may retain the discretion to

increase or decrease the amount payable pursuant to a performance-based award. The Executive Compensation Committee may adjust the

performance goals and the method of calculating the attainment of the performance goals to take into account events that occur during a

performance period including, but not limited to: (i) asset write-downs; (ii) litigation or claim judgments or settlements; (ii) the effect of changes in or

provisions under tax law, accounting principles or other laws or provisions affecting reported results; (iv) charges for any reorganization and

restructuring programs; (v) any extraordinary, unusual, or other infrequently occurring items as described in Accounting Standards Codification

225-20-20 (as amended by Accounting Standards Update No. 2015-01) or in management’s discussion and analysis of financial condition and

results of continuing operations appearing in our annual report to shareholders for the applicable year; (vi) the impact of mergers, acquisitions or

divestitures; (vii) foreign exchange gains and losses; and (viii) gains or losses on asset sales.

Limit on Non-Employee Director Compensation: The maximum number of shares that may be granted under the 2025 EIP or otherwise during

any calendar year to a non-employee director, taken together with any cash fees we pay to such non-employee director during such year for service

on our Board, will not exceed $ 1,000,000 in total value. Additional information about Director Stock Awards is provided in the “Director Stock Awards”

section above.

Termination of Employment or Service: The Executive Compensation Committee will specify, at or after the time of grant of an award, the effect, if

any, that a participant’s termination of service or the participant’s death or disability will have on the vesting, exercisability, or payout of the award.

Such provisions will be determined by the Executive Compensation Committee in its discretion, will be included in the applicable award agreement

and need not be uniform among all awards or among all participants.

Change in Participant’s Status: The Executive Compensation Committee has the discretion to determine the effect upon an award in the event that

a participant experiences a change in status, as the result of (i) the participant’s employer or the entity by which the participant is engaged ceasing to

be our subsidiary, (ii) any leave of absence approved by us or a subsidiary, (iii) any transfer between locations of employment with us or a subsidiary

or between subsidiaries, (iv) any change in status from an employee to a consultant or director, or vice versa, and (v) at our request or the request of

a subsidiary, the participant's becoming employed by any partnership, joint venture, corporation or other entity not meeting the requirements to be a

subsidiary under the 2025 EIP.

Change in Control: Unless the Executive Compensation Committee provides otherwise, if we have a change in control in which outstanding awards

are assumed, continued or replaced with equivalent awards of substantially the same value by the successor, the Executive Compensation

Committee will measure performance as of the date of the change in control for all outstanding awards of performance units, performance shares

and other performance-based awards granted prior to the change in control based on the greater o f (i) the payout at the target number of

performance units, performance shares and other performance-based awards granted for the entire performance period or (ii) the payout based upon

the actual performance level attained as of the date of the change in control, in each case, after giving effect to the accumulation of dividend

equivalents, and the participant will continue to vest in such awards based on the participant’s continued service.

Unless the Executive Compensation Committee provides otherwise, if we have a change in control in which outstanding awards are assumed,

continued or replaced with equivalent awards of substantially similar value by the successor, if the participant’s employment is terminated without

cause (as defined in the 2025 EIP) or the participant resigns for good reason (as defined in the 2025 EIP), in each case within the two years

following the change in control, the following will apply with respect to the assumed, continued or replaced awards: (i) restrictions imposed on

outstanding RSUs and restricted stock awards granted prior to the change in control will lapse, and RSUs will be paid in cash or in shares, as

determined by the Executive Compensation Committee; (ii) outstanding performance units, performance shares and other performance-based

awards will be paid at the greater of (a) the payout at the target number of performance units, performance shares or other performance-based

awards granted for the entire performance period, or (b) the payout based upon the actual performance level attained as of the date of the change in

control, in each case giving effect to the accumulation of dividend equivalents, and the awards will be paid in cash or in shares, as determined by the

Executive Compensation Committee; (iii) all earned performance units, performance shares and other performance-based awards (as increased by

any dividend equivalents to the date of payment) not yet paid out will be immediately paid out in cash or in shares, as determined by the Executive

Compensation Committee; (iv) all outstanding options and SARs will become immediately exercisable, and NQSOs and SARs will be exercisable

after the date of the participant’s termination for a period equal to the lesser of the remaining term of the award or 12 months; and (v) any restrictions

imposed on outstanding other awards shall be deemed to have expired. If a participant’s employment is terminated without cause prior to the date of

a change in control but the participant demonstrates that the termination was in connection with, or in anticipation of, the change in control in

accordance with the terms of the 2025 EIP, the participant’s termination will be deemed to have occurred after the change in control for purposes of

the 2025 EIP so long as the change in control actually occurs.

Unless the Executive Compensation Committee provides otherwise, for outstanding awards that will not be assumed, continued, or replaced with

equivalent awards of substantially similar value by the successor, the following will occur as a result of the change in control: (i) restrictions imposed

on outstanding RSUs and restricted stock awards will lapse, and RSUs will be paid in cash or shares, as determined by the Executive Compensation

Committee; (ii) with respect to outstanding performance units, performance shares and other performance-based awards, the participant will receive

the greater of (a) the payout at the target number of performance units, performance shares or other performance-based awards for the entire

performance period, and (b) the payout based upon the actual performance level attained as of the change in control date, in each case giving effect

to the accumulation of dividend equivalents, and the awards will be paid in cash or in shares, as determined by the Executive Compensation

Committee; (iii) all earned performance units, performance shares other performance-based awards (as increased by any dividend equivalents to the

date of payment) not yet paid out will be immediately paid out in cash or shares, as determined by the Executive Compensation Committee; (iv) all

outstanding options and SARs will become immediately exercisable for a period of time determined by the Executive Compensation Committee, and

112 2025 ONEOK, Inc. Proxy Statement

PROPOSAL 3: Approval of the ONEOK, Inc. 2025 Equity Incentive Plan

the Executive Compensation Committee may, in its discretion, for options and SARs relating to shares with a value greater than the exercise price

and not exercised upon the change in control, cancel the awards in exchange for an amount equal to the difference, if any, between the exercise

price and the then value of the shares, and for other options and SARs, such options and SARs may be cancelled without payment of consideration;

and (v) any restrictions imposed on outstanding other awards shall be deemed to have expired.

No tax gross up will be provided with respect to tax consequences of awards granted under the 2025 EIP under Section 280G or 4999 of the Code .

Adjustments: The existence of the 2025 EIP and any award agreement will not affect or restrict our right to effect corporate changes or acts. In the

event of any change in the outstanding common stock by reason of any merger, amalgamation, reorganization, consolidation, recapitalization,

reclassification, stock dividend, bonus issues, extraordinary cash dividend, stock split, reverse stock split, share consolidation or subdivision, spin-off,

split-off or similar transaction or other change in corporate structure affecting our common stock, the Executive Compensation Committee shall make

such adjustments and substitutions as it deems equitable or appropriate. Such adjustments may include, without limitation, adjustments in the

aggregate number, class and kind of securities that may be delivered, in the aggregate or to any one participant; and in the number, class, kind and

option or exercise price of securities subject to outstanding awards.

Restrictions on Transferability: In general, awards will not be assignable or transferable other than by will or by the laws of descent and distribution.

Prohibition on Repricing and Cash Buyouts: The 2025 EIP will not permit repricing of options or SARs or the cancellation, exchange or surrender

of underwater options or SARs for cash or other awards without shareholder approval, except in connection with a change in our capitalization.

Recoupment: All awards granted under the 2025 EIP, all shares issued with respect to such awards, any payments made under the 2025 EIP, and

any gains realized upon the exercise or settlement of an award are subject to the terms of any applicable clawback or recoupment policies approved

by the Board or the Executive Compensation Committee, whether approved before or after the date awards are granted under the 2025 EIP. Any

amount required to be clawed back, recouped or forfeited under such policies will be deemed to have not been earned under the 2025 EIP and

applicable award agreemen t. S ee “Clawback Policy” above at page 90 .

Claims Procedure: The 2025 EIP sets forth mandatory claims procedures that are intended to reduce the likelihood of disputes between a

participant and us in connection with the 2025 EIP and, to the extent a dispute arises, to lessen the time, expense, complexity and uncertainty

associated with resolving the dispute. The claims procedures include the following: a one-year limit on a participant’s right to bring a claim;

requirements as to the form of claim; a requirement that any dispute based on a denied claim be resolved by binding arbitration; a six-month limit on

a participant’s right to request arbitration of a denied claim; specific rules for arbitration; deference given to administrative decisions unless they are

arbitrary, capricious, or unlawful; and provisions related to venue, arbitration costs and attorneys’ fees.

Amendment and Termination of the Plan: The Board may amend or modify the 2025 EIP at any time. However, shareholder approval would have

to be obtained for any amendment or modification if such approval is required by law or regulation or under the NYSE rules, which generally require

shareholder approval for material plan changes, including increasing the number of shares authorized for issuance, materially modifying participation

requirements, and changing the restrictions on repricing . The 2025 EIP will terminate on the day immediately before the tenth anniversary of the

2025 EIP Effective Date. The Board may terminate the 2025 EIP earlier in its sole discretion. No such amendment, modification or termination of the

2025 EIP may adversely affect in any material way any award then outstanding under the 2025 EIP without the affected participant’s written consent,

unless otherwise provided in the 2025 EIP or required by law. Awards that are outstanding upon termination of the 2025 EIP will remain in effect in

accordance with the terms of the 2025 EIP and any applicable award agreement.

U.S. FEDERAL INCOME TAX CONSEQUENCES

The following is only a general summary of the U.S. federal income tax consequences related to certain awards that may be granted under the 2025

EIP based on the tax laws in effect on the date of this proxy statement. The federal tax laws may change, and the federal, state and local tax

consequences for any participant will depend on his or her individual circumstances. This summary does not address all potential tax consequences

related to awards, such as estate and gift laws, foreign taxes, and state and local taxes.

Restricted Stock, RSUs, Performance Shares and Performance Units: A participant who has been granted a restricted stock award, RSUs,

performance shares or performance units under the 2025 EIP will generally recognize as taxable income the fair market value of the restricted stock,

RSUs, performance shares or performance units on the date the restricted or performance period ends over the amount, if any, paid for the shares.

We are generally entitled to a corresponding tax deduction at the same time. A participant may elect to include the value of a restricted stock award

as income at the time it is granted under Section 83(b) of the Tax Code, and we will generally be eligible for a corresponding tax deduction for the

same amount at that time.

2025 ONEOK, Inc. Proxy Statement 113

PROPOSAL 3: Approval of the ONEOK, Inc. 2025 Equity Incentive Plan

Nonqualified Options and SARs: A participant will not recognize taxable income upon the grant of a NQSO or SAR. The participant generally will

recognize ordinary income upon exercise, in an amount equal to the difference between the exercise price or base price of the shares and the fair

market value of the shares received at the time of exercise (including any shares withheld by us to satisfy tax withholding obligations). We will

generally be entitled to a corresponding tax deduction for the same amount.

Incentive Stock Options: A participant will not recognize taxable income when an ISO is granted or exercised. Similarly, we are not entitled to any

tax deduction at the time of grant or at the time of exercise. However, the excess of the fair market value of the covered shares over the exercise

price on the date of exercise is an item of tax preference for alternative minimum tax purposes. If the participant exercises the option and holds the

acquired shares for more than two years following the date of the option grant and more than one year after the date of exercise, the difference

between the sale price and exercise price will be taxed as long-term capital gain or loss. Under such circumstances, we will not be entitled to any tax

deduction. If the participant sells the acquired shares before the end of the two-year and one-year holding periods, the participant generally will

recognize ordinary income at the time of sale equal to the fair market value of the shares on the exercise date (or the sale price, if less) minus the

exercise price of the option. Any additional gain will be long-term capital gain if the shares have been held for more than one year. Under such

circumstances, we generally will be entitled to a corresponding tax deduction equal to the amount of ordinary income recognized by the participant.

Tax Code Section 409A: Certain awards under the 2025 EIP, depending in part on the specific terms and conditions of such awards, may be

considered “nonqualified deferred compensation” subject to the requirements of Section 409A of the Tax Code, which regulates deferred

compensation arrangements. If the terms and/or administration of such awards do not meet the requirements of Section 409A of the Tax Code, then

the failure to do so may result in an additional 20% federal tax obligation, plus penalties and interest, for the participant. The 2025 EIP is designed

such that any award subject to the requirement of Section 409A is intended to be administered accordingly, but there is no guarantee that all awards

will ultimately be viewed as compliant by the Internal Revenue Service.

Tax Code Section 162(m): Section 162(m) of the Tax Code disallows a tax deduction to a publicly held company for compensation in excess of $1

million paid to any of its “covered employees,” which generally include the chief executive officer, chief financial officer and the next three most highly

compensated officers. Once an employee is determined to be a covered employee under these provisions, such employee will remain a covered

employee regardless of future changes to the employee’s title or compensation. The term “covered employees” will be expanded beginning with tax

years after December 31, 2026 to include the company's five highest paid employees during the year (other than an employee who is already a covered

employee by reason of being the chief executive officer, chief financial officer and the next three most highly compensated officers during that year).

As in prior years, while the deductibility of executive compensation for federal income tax purposes is among the factors the Executive Compensation

Committee considers when structuring our executive compensation arrangements, it is not the sole or primary factor considered this year. We retain

the flexibility to authorize compensation that may not be deductible if we believe it is in our best interests.

NEW PLAN BENEFITS

The 2025 EIP will not become effective unless it is approved by the shareholders at the annual meeting. Future benefits under the 2025 EIP

generally will be granted at the discretion of the Executive Compensation Committee and therefore are not currently determinable. No awards have

been granted that are contingent on the approval of the 2025 EIP.

VOTE REQUIRED AND BOARD OF

DIRECTORS RECOMMENDATION

Th e affirmative vote of the holders of shares of our common stock representing a majority of the voting power of shareholders present online or by

proxy and entitled to vote upon the proposal at the 2025 annual meeting is required for approval of this Proposal No. 3.

THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE IN FAVOR OF THIS PROPOSAL NO. 3 TO APPROVE THE

2025 EIP.

114 2025 ONEOK, Inc. Proxy Statement

Approval of the ONEOK, Inc. 2025 Employee Stock Award Program
●	Our Board unanimously recommends a vote FOR the approval of the 2025 Employee Stock Award Program.

I NTRODUCTION

We are asking our shareholders to approve the ONEOK, Inc. 2025 Employee Stock Award Program (the “2025 ESAP”) pursuant to which 700,000

shares of our common stock will be reserved for issuance under the 2025 ESAP, subject to adjustment as described below. Our Board adopted the

2025 ESAP on February 19, 2025 upon the recommendation of the Executive Compensation Committee, subject to shareholder approval at the

2025 annual meeting. If approved by a majority of the voting power of shareholders present online or by proxy and entitled to vote upon the proposal

and at the 2025 annual meeting, the 2025 ESAP will become effective as of the date of such shareholder approval (the “2025 ESAP Effective Date”).

The 2025 ESAP is intended to be the successor to the ONEOK Employee Stock Award Program (the “Prior ESAP”), which terminated as of

November 7, 2024. Accordingly, we currently do not have an employee stock award program in effect.

The 2025 ESAP is designed to award our eligible employees and the eligible employees of our direct or indirect subsidiaries with one share of our

common stock for no monetary consideration when certain share price benchmarks are attained as described further below. The Board believes that

it is in the best interests of our shareholders to provide an incentive to our employees for their contributions toward our success as reflected in our

common stock price, as well as to provide employees with the opportunity to hold an ownership interest in the company through their participation in

the 2025 ESAP and thereby align their interests with those of our shareholders.

Approximately 6,300 (including 68 executive officers) employees would have been eligible to participate in the 2025 ESAP had the 2025 ESAP been

in effect on March 1, 2025.

The closing price of a share of our common stock on February 28, 2025 (the last trading day prior to March 1, 2025) was $100.39.

A copy of the 2025 ESAP is attached to this proxy statement as Appendix B.

SHARES TO BE AUTHORIZED UNDER

THE PROGRAM

Subject to adjustment as described below, if approved, the aggregate number of shares of our common stock that will be reserved for issuance

under the 2025 ESAP will be 700,000 shares .

We believe that approval of the 2025 ESAP, including the number of shares requested, will give us flexibility to continue to issue shares to eligible

employees for approximately ten years in amounts determined in accordance with the 2025 ESAP. This time period is an estimate. The actual rate at

which we use shares under the 2025 ESAP may be more or less than our anticipated future usage and will depend upon various unknown factors,

such as the future price of our common stock, issuance levels and the number of employees. Additionally, as the issuance of shares under the 2025

ESAP is dependent upon the achievement of certain share price benchmarks, our ability to predict share usage under the 2025 ESAP is limited, as

prediction with respect to future share price performance is entirely speculative.

In recommending the number of shares to be reserved for issuance under the 2025 ESAP to the Board, the Executive Compensation Committee

considered our historical share prices, proxy advisory firm policies and anticipated shareholder reaction. The Executive Compensation Committee

and the Board also considered the advice of Meridian Compensation Partners, the Executive Compensation Committee’s independent

compensation consultant.

2025 ONEOK, Inc. Proxy Statement 115

PROPOSAL 4: Approval of ONEOK, Inc. 2025 Employee Stock Award Program

SUMMARY OF THE 2025 ESAP

The following is a summary of the principal features of the 2025 ESAP. This summary, however, is not intended to be a complete description of all

the provisions of the 2025 ESAP and is qualified in its entirety by the full text of the 2025 ESAP, a copy of which is attached to this proxy statement

as Appendix B.

Administration: The Board or Executive Compensation Committee will administer the 2025 ESAP and have discretion to make determinations with

respect to the 2025 ESAP. However, the Board will make all decisions to grant awards under the 2025 ESAP.

The Board or Executive Compensation Committee may delegate administrative duties (but not decisions with respect to grant of awards) to any one

or more of its members or to members of management.

Shares Subject to the 2025 ESAP: If approved, the number of shares of our common stock that will be reserved for issuance under the 2025 ESAP

is 700,000 shares of common stock, subject to adjustment as described below. When the shares available for issuance under the 2025 ESAP are no

longer sufficient to ensure that all eligible employees will receive one share of our common stock on a particular Benchmark Date (as defined below),

no further shares will be issued under the 2025 ESAP. If the 2025 ESAP is approved by shareholders, the number of shares available for issuance

under the 2025 ESAP will represent less than 1% of our issued and outstanding shares as of March 1 , 2025 . See the Dilution Analysis in Proposal

No. 3 above.

Shares of our common stock may be issued under the 2025 ESAP from our authorized but unissued shares, treasury shares, shares we purchase

on the open market, or any combination of the above.

In the event of any merger, amalgamation, reorganization, consolidation, recapitalization, reclassification, stock dividend, bonus issues, extraordinary

cash dividend, stock split, reverse stock split, share consolidation or subdivision, spin-off, split-off or similar transaction or other change in corporate

structure affecting our common stock, the Board or Executive Compensation Committee will make adjustments and other substitutions as the Board

or Executive Compensation Committee deems equitable or appropriate, including, without limitation, the following: (i) equitably adjust the number

and kind of shares available for issuance under the 2025 ESAP to reflect the impact of the event; and (ii) for purposes of determining whether a

Benchmark Date has occurred, equitably adjust the applicable price threshold and the closing price to reflect the event. Upon the occurrence of such

an event, the incremental threshold that triggers a Benchmark Date and the issuance of additional shares under the 2025 ESAP pursuant to the

automatic awards will remain one dollar. The Board or Executive Compensation Committee also have the authority to make any other adjustments it

deems appropriate in the event of changes affecting our common stock.

Share Issuances under the 2025 ESAP: The 2025 ESAP provides for the issuance to all eligible employees of one share of our common stock (or

more in the case of discretionary awards as described further below) for no consideration under certain circumstances.

We will make an initial share issuance when, on or following the 2025 ESAP Effective Date, the per share closing price of our common stock on the

NYSE attains the next whole one dollar increment above the all-time highest closing price of our common stock on the NYSE before the 2025 ESAP

Effective Date (the “Base Share Price”). The date on which such share price is attained is referred to as the “Initial Benchmark Date.” Subsequently,

we will issue one additional share of our common stock, for no consideration, to all eligible employees when the per share closing price of our

common stock on the NYSE is for the first time at or above each one dollar increment above the Base Share Price. Each such date, together with the

Initial Benchmark Date and any benchmark date for a discretionary award as described below, is referred to as a “Benchmark Date”. Each eligible

employee will be awarded one share of our common stock based on the achievement of each price threshold on each Benchmark Date, except

for discretionary awards, in which case eligible employees will be awarded one share of our common stock for the attainment of each specified

price threshold.

The “closing price” is the last sale price, regular way, of our common stock as reported on the principal consolidated transaction system with respect

to securities listed or admitted to trading on the NYSE.

The Board may issue additional shares of our common stock under the 2025 ESAP to eligible employees in its sole discretion if the Board

determines that the closing price of our common stock has attained one or more specified price thresholds at or before the date of the award and the

circumstances warrant an issuance of additional shares. If the Board so determines, eligible employees will each be awarded, for no monetary

consideration, one additional share of our common stock based on the attainment of each such price threshold at such time as the Board deems

appropriate. The Benchmark Date for purposes of any discretionary awards is the date, on or after the 2025 ESAP Effective Date, on which the

Board approves the discretionary awards.

The shares of our common stock issued under the 2025 ESAP will be issued by our transfer agent, Equiniti Trust Company, LLC (“EQ”), and will be

deposited to each employee’s account at EQ in book entry form within a reasonable time after each Benchmark Date.

116 2025 ONEOK, Inc. Proxy Statement

PROPOSAL 4: Approval of ONEOK, Inc. 2025 Employee Stock Award Program

Eligibility and Participation: Eligible employees under the 2025 ESAP are active, full-time U.S. employees of ours and our direct and indirect

subsidiaries, as well as any full-time U.S. employees of ours and our direct and indirect subsidiaries who are on short-term disability, as of the

Eligibility Date (as defined below) for each issuance under the 2025 ESAP. Only employees working in the U.S. are eligible for the 2025 ESAP. The

Eligibility Date is the applicable Benchmark Date of each issuance of our common stock under the 2025 ESAP.

Shareholder Rights: Employees will not have any shareholder rights with respect to the shares issuable under the 2025 ESAP until the shares are

actually issued and the employees become the holders of record of such shares. Employees holding shares issued under the 2025 ESAP will have

the same voting rights as all other holders of our common stock.

Dividends: Employees holding shares issued under the 2025 ESAP will receive any dividends with respect to such shares when dividends are paid

as declared by the Board.

Disposition of Shares Issued: Eligible employees who are issued shares of our common stock under the 2025 ESAP will be able to sell the shares

after they are issued, subject to the terms of any applicable stock ownership guidelines, the ONEOK Securities/Insider Trading Policy, any applicable

blackout periods, and resale restrictions arising pursuant to the Securities Act of 1933, as amended.

Certain Other Limitations: Employees holding shares issued under the 2025 ESAP will not be able to transfer such shares into our 401(k) plan,

Employee Stock Purchase Plan, or other plan.

All shares of our common stock issued under the 2025 ESAP will be subject to the terms of any applicable clawback policies approved by the Board

or the Executive Compensation Committee, as in effect from time to time, whether approved before or after the date of issuance of shares of our

common stock under the 2025 ESAP. See "Clawback Policy" above at page 90 .

Amendment and Termination: The 2025 ESAP will terminate on the day immediately before the tenth anniversary of the 2025 ESAP Effective

Date, if not sooner terminated as described below. We reserve the right to, at any earlier date, terminate, suspend or modify the 2025 ESAP, in

whole or in part, at any time, by action of the Board unless shareholder approval is required by law or regulation or under the NYSE rules, which

generally require shareholder approval for material plan changes, including increasing the number of shares authorized for issuance and materially

modifying participation requirements. If approved, the 2025 ESAP will continue in effect until terminated in accordance with its terms.

U.S. FEDERAL INCOME TAX CONSEQUENCES

The following is only a general summary of the U.S. federal income tax consequences related to the awards that may be granted under the 2025

ESAP based on the tax laws in effect on the date of this proxy statement. The federal tax laws may change, and the federal, state and local tax

consequences for any participant will depend on his or her individual circumstances. This summary does not address all potential tax consequences

related to awards, such as estate and gift laws, foreign taxes, and state and local taxes.

The fair market value of a share of stock issued to an employee under the 2025 ESAP is treated as taxable compensation income realized by the

employee at the time the employee receives the share. This amount will be subject to withholding of income tax and employment taxes (Social

Security and Medicare). The company will generally be entitled to a deduction for federal income tax purposes at the time such compensation

income is realized by the employee, in an amount equal to the income realized by the employee.

The shares of our common stock awarded under the 2025 ESAP generally will be considered a capital asset for tax purposes. The basis for

determining gain or loss on any sale of the stock will be the amount the employee includes in gross income at the time the employee receives the stock.

If the employee holds the stock for one year or less after it is received, gain or loss on its sale generally will be short-term gain or loss. If the

employee holds the stock for more than one year after it is received, gain or loss from its sale generally will be long-term capital gain or loss.

Tax Code Section 162(m)

Section 162(m) of the Tax Code disallows a tax deduction to a publicly held company for compensation in excess of $1 million paid to any of its

“covered employees,” which generally include the chief executive officer, chief financial officer and the next three most highly compensated officers.

Once an employee is determined to be a covered employee under these provisions, such employee will remain a covered employee regardless of

future changes to the employee’s title or compensation. The term “covered employees” will be expanded beginning with tax years after December

31, 2026 to include the company's five highest paid employees during the year (other than an employee who is already a covered employee by

reason of being the chief executive officer, chief financial officer and the next three most highly compensated officers during that year).

As in prior years, w hile the deductibility of executive compensation for federal income tax purposes is among the factors the Executive Compensation

Committee considers when structuring our executive compensation arrangements, it is not the sole or primary factor considered this year. We retain

the flexibility to authorize compensation that may not be deductible if we believe it is in our best interests.

PROPOSAL 4: Approval of ONEOK, Inc. 2025 Employee Stock Award Program

NEW PLAN BENEFITS

The 2025 ESAP will not become effective unless it is approved by the shareholders at the annual meeting, and no shares have been issued under

the 2025 ESAP subject to shareholder approval . Awards under the 2025 ESAP will not be made until the Base Share Price is attained or as

otherwise determined by the Board in its sole discretion. Therefore, the benefits or amounts that will be received by eligible employees under the

2025 ESAP are not currently determinable. No awards have been granted that are contingent on the approval of the 2025 ESAP.

VOTE REQUIRED AND BOARD OF

DIRECTORS RECOMMENDATION

The affirmative vote of the holders of shares of our common stock representing a majority of the voting power of shareholders present online or by

proxy and entitled to vote on the proposal and at the 2025 annual meeting is required for approval of this Proposal No. 4.

THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE IN FAVOR OF THIS PROPOSAL NO. 4 TO APPROVE THE

2025 ESAP.

Advisory Vote on Executive Compensation
●	Our Board unanimously recommends a vote FOR the approval of the compensation of our named executive officers, as disclosed in this proxy statement pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, the compensation tables and the related narrative discussion.

INTRODUCTION

The Dodd-Frank Act added provisions to Section 14A of the Exchange Act to provide that a public company’s proxy statement in connection with the

company’s annual meeting of shareholders must, at least once every three years, allow shareholders to cast a non-binding, advisory “say-on-pay”

vote regarding the compensation of the company’s named executive officers as disclosed pursuant to Item 402 of Securities and Exchange

Commission Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion. Section 14A of

the Exchange Act, as amended by the Dodd-Frank Act, also requires us, not less frequently than once every six years, to provide our shareholders

the opportunity to vote, on a non-binding advisory basis, on the frequency with which we will submit to shareholders a “say-on-pay” advisory vote.

At our 2023 annual meeting of shareholders, a substantial majority of our shareholders voted for an annual say-on-pay vote. Based on these results,

we have provided our shareholders with an annual, non-binding, advisory say-on-pay vote on executive compensation. Unless the Board modifies its

determination on the frequency of future say-on-pay advisory votes, our next advisory say-on-pay vote is expected to occur at our 2026 annual

meeting of shareholders.

OUR EXECUTIVE COMPENSATION PROGRAM

As described in the Compensation Discussion and Analysis section of this proxy statement and the compensation tables and narrative discussion set

forth above, our executive compensation program is based on our pay-for-performance philosophy and is designed with the following goals in mind:

• Pay-for-Performance: to align the interests of our executive officers with the interests of our shareholders;

• Compensation Aligned with Business Strategies: to attract, retain and motivate highly talented executives who are critical to the successful

implementation of our strategic plan;

• Pay Equity: to pay our executives fairly relative to one another and to our industry peers based on their responsibilities, experience and

performance; and

• Compensation Governance Best Practices: to implement sound governance practices by implementing executive compensation best practices

and policies.

Our Executive Compensation Committee regularly reviews the compensation program for our named executive officers to assess its effectiveness in

delivering on these goals.

Examples of how the various elements of our compensation program for our named executive officers are linked to company performance and are

designed to achieve the goals set forth above include:

• At-Risk Pay: a substantial portion of our named executive officers’ compensation is “variable” or “at-risk” incentive compensation, meaning that it

is tied to our performance relative to various short-term and long-term objectives, which are based on a number of financial and operational goals;

• Awards are Capped: awards to each named executive officer are subject to fixed maximums established by our Executive

Compensation Committee;

• Multiple Performance Measures: short-term incentive awards are based on a review of a variety of indicators of performance, rather than any

single indicator of performance;

2025 ONEOK, Inc. Proxy Statement 119

PROPOSAL 5: Advisory Vote on Executive Compensation

• Prudent Risk Management: short- and long-term incentive awards are not tied to formulas that could focus our named executive officers on

specific short-term outcomes;

• Executive Compensation Committee Assessment: the Executive Compensation Committee approves the final annual incentive plan awards

after review and confirmation of executive, operating and financial performance;

• Clawbacks: short-term cash and long-term equity incentive awards are subject to our Compensation Recoupment Policy and discretionary

clawback provisions;

• Long-Term Performance Period: for named executive officers, a significant portion of incentive award value is delivered in the form of our stock-

based compensation that vests over multiple years;

• Majority Performance-Based Equity: for executive officers, approximately 80% of long-term, stock-based incentive amounts are in the form of

performance units; and

• Robust Share-Ownership Guidelines: executive officers are subject to our share-ownership guidelines.

For additional information on the compensation program for our named executive officers, including specific information about compensation in fiscal

year 2024, please read “Executive Compensation Discussion and Analysis,” along with the subsequent tables and narrative descriptions, beginning

on page 73 .

Following our 2024 annual meeting of shareholders, the Executive Compensation Committee considered the affirmative vote by 95.4% of our

shareholders who voted on our executive compensation , including abstentions, at our 2024 annual meeting of shareholders and determined to

continue to apply the same principles the Committee has used historically in determining the nature and amount of executive compensation.

For the reasons discussed above, the Board recommends that shareholders vote in favor of the following resolution:

“RESOLVED, that the shareholders hereby approve, on an advisory basis, the compensation paid to the named executive officers, as disclosed in

the company’s proxy statement for the 2025 annual meeting of shareholders pursuant to Item 402 of Regulation S-K, including the Compensation

Discussion and Analysis, compensation tables and narrative discussion.”

VOTE REQUIRED AND BOARD OF

DIRECTORS RECOMMENDATION

This vote is advisory and will not be binding on the company, our Board or our Executive Compensation Committee. Our Board and our Executive

Compensation Committee value the opinions of our shareholders and, to the extent there is any significant vote against the named executive officer

compensation as disclosed in this proxy statement, we will consider our shareholders’ concerns, and the Executive Compensation Committee will

evaluate whether any actions are necessary to address those concerns.

In accordance with our By-laws, approval of this proposal requires the affirmative vote of a majority of the voting power of the shareholders present

online or by proxy and entitled to vote on this proposal at the meeting. Abstentions will have the same effect as votes against this proposal and

broker non-votes do not count as entitled to vote for purposes of determining the outcome of the vote on this proposal.

OUR BOARD UNANIMOUSLY RECOMMENDS A VOTE IN FAVOR OF THE APPROVAL OF THE COMPENSATION OF OUR NAMED

EXECUTIVE OFFICERS, AS DISCLOSED IN THIS PROXY STATEMENT PURSUANT TO ITEM 402 OF REGULATION S-K, INCLUDING THE

COMPENSATION DISCUSSION AND ANALYSIS, THE COMPENSATION TABLES AND THE RELATED NARRATIVE DISCUSSION.

RELATED-PERSON TRANSACTIONS

Our Board recognizes that transactions in which we participate and in which a related person (executive officer, director, director nominee, 5% or

greater shareholder, and immediate family members of any of the foregoing) has a direct or indirect material interest can present potential or actual

conflicts of interest. These transactions can also create the appearance that company decisions are based on considerations other than the best

interests of the company and its shareholders.

Accordingly, as a general matter, it is our preference to avoid related-person transactions. Nevertheless, we recognize that there are situations in

which related-person transactions may be in, or not inconsistent with, the best interests of the company and its shareholders including, but not limited

to, situations in which we provide products or services to related persons on an arm’s length basis and on terms comparable with those provided to

unrelated third parties.

In the event we propose to enter into a transaction in which an executive officer (other than an employment relationship), director (other than

compensation arrangements for service on our Board provided to each director), director nominee, 5% or greater shareholder, or an immediate

family member of any of the foregoing has a direct or indirect material interest, the proposed transaction is presented to our Audit Committee and, if

warranted, our Board, for review to determine if the transaction creates a conflict of interest and, if so, whether it is otherwise fair to the company. In

determining whether a particular transaction creates a conflict of interest and, if so, is fair to the company, our Audit Committee and, if warranted, our

Board, consider the specific facts and circumstances applicable to each such transaction, including: the parties to the transaction, their relationship to

the company and the nature of their interest in the transaction; the nature of the transaction; the aggregate value of the transaction; the length of the

transaction; whether the transaction occurs in the normal course of our business; the benefits to our company provided by the transaction; if

applicable, the availability of other sources of comparable products or services; and, if applicable, whether the terms of the transaction, including

price or other consideration, are the same or substantially the same as those available to the company if the transaction were entered into with an

unrelated party.

We require each executive officer and director to annually provide us a written disclosure of any transaction in which we participate and in which the

officer or director or any of his or her immediate family members has a direct or indirect material interest. Our Corporate Governance Committee

reviews these disclosures of related-party transactions in connection with its annual review of director independence. These procedures are not in

writing but are documented through the meeting agendas and minutes of our Audit and Corporate Governance Committees.

The following is required to be disclosed by Securities and Exchange Commission regulations regarding transactions with related persons:

Charles M. Kelley II, son of Charles M. Kelley, our Senior Vice President, Natural Gas Pipelines, is employed by us as an Account Director and his

total compensation during 2024 was in excess of $120,000.

December 31, 2023, and 20.80%, based on 1.14-years historical price data as of December 31, 2024. In comparison, the risk-free interest rate and the annualized

3-year historical volatility used at the time of grant for all outstanding 2023 NEO PSUs were 4.43% and 63.3%, respectively.

For PSUs granted February 21, 2024 , the risk-free interest rate used in the fair value valuation adjustment was 4.25% and the historical stock price volatility used

Hulse, III, Kevin L. Burdick, Sheridan C. Swords, and Lyndon C. Taylor.

(5) TSR is calculated from December 31, 2019 to the end of the applicable fiscal year.

(6) Peer Group TSR is the S&P 500 Energy Index: We replaced the Alerian Midstream Energy Select Index with the S&P 500 Energy Index as it is more relevant to

our business subsequent to the Magellan acquisition. The S&P 500 Energy Index is a subindex of the S&P 500 that includes those companies classified as

members of the energy sector. The graph below includes both peer groups for comparison purposes through FY 2024.

(7) In accordance with Securities and Exchange Commission rules, we are required to include in the "Pay versus Performance" table the "most important" financial

performance measure (as determined by the company) used to link compensation actually paid to our NEOs to company performance. The company determined

diluted EPS meets this requirement. Diluted EPS is as reflected in our 2024 annual report to shareholders (which includes our Annual Report on Form 10-K for the

year ended December 31, 2024).

The following graph reflects the relationship between compensation actually paid and our cumulative TSR. (TSR reflects the value of a $100

transaction under SEC Rule 16b-3; provided, that any transaction under the Plan involving a Section 16 Person also may be approved by the Board

of Directors, or may be approved or ratified by the shareholders of the Company, in the manner that exempts such transaction under SEC

and powers to the Company’s Benefit Plan Administration Committee or the Company’s Chief Executive Officer pursuant to a duly adopted resolution

or a memorandum of action signed by all members of the Committee or approved via electronic transmission. The Committee may, at any time,

revoke any such allocation or delegation. All actions taken by the Company’s Benefit Plan Administration Committee or the Company’s Chief

Executive Officer pursuant to a valid delegation shall have the same legal effect and shall be entitled to the same deference as if taken by the

Committee itself. Notwithstanding the foregoing, neither the Company’s Benefit Plan Administration Committee nor the Company’s Chief Executive

Officer shall have the right to grant Awards to persons who are subject to Section 16 of the Exchange Act.

2.4. Decisions Binding. All determinations and decisions made by the Committee pursuant to the Plan and all related Board

decisions and actions shall be final, conclusive and binding on all persons interested in the Plan or an Award. The Committee shall consider such

factors as it deems relevant to making its decisions, determinations and interpretations including, without limitation, the recommendations or advice

of any Director, officer or employee of the Company or a Subsidiary and such agents, attorneys, consultants and accountants as it may select. The

Committee’s determinations under the Plan need not be the same for all persons. A Participant or other holder of an Award may contest a decision or

action by the Committee with respect to such person or Award in accordance with Article 13, and only on the grounds that such decision or action

was arbitrary or capricious or was unlawful.

2.5. Limitation of Liability . Members of the Board of Directors, members of the Committee or any person to whom authority was

delegated in accordance with Section 2.3 above shall, when acting under this Plan, be fully protected in relying in good faith upon the advice

incur no liability except for gross or willful misconduct in the performance of their duties.

2.6. Action by the Board . Notwithstanding anything in the Plan to the contrary, any authority or responsibility, which, under the

terms of the Plan, may be exercised by the Committee may alternatively be exercised by the Board.

issued or delivered under the Plan shall not exceed 16,870,000 Shares, plus 2,279,829 Shares, which is the number of Shares reserved for

issuance under the 2018 Plan that remained available for awards under the 2018 Plan as of March 1, 2025 and which shall be reduced by the

number of Shares underlying any grants made under the 2018 Plan after March 1, 2025 and before the Effective Date. In addition, as described

below, any Shares subject to an outstanding award under the 2018 Plan that, following the Effective Date, expires, or is terminated, surrendered or

forfeited for any reason without issuance of such shares, or is settled in cash, shall be available for new Awards under this Plan, subject to

adjustment as provided in Section 3.3 below. Shares issued under the Plan may consist, in whole or in part, of authorized but unissued Shares,

treasury Shares or Shares reacquired by the Company in any manner, or a combination thereof.

3.2. Share Counting . The number of Shares remaining available for issuance as of any point in time shall be reduced by the

number of Shares subject to outstanding Awards and, for Awards that are not denominated by Shares, by the number of Shares actually delivered

upon settlement or payment of an Award on or after the Effective Date. Notwithstanding anything in the Plan to the contrary, Shares subject to an

Award under this Plan or under the 2018 Plan will again be available for grant and issuance pursuant to the Plan to the extent the relevant Awards:

(a) terminate by expiration, forfeiture, cancellation, or otherwise without the issuance of Shares or (b) are settled in cash in lieu of Shares. Shares

subject to an Award may not again be made available for grant and issuance pursuant to the Plan if such Shares are: (w) subject to an Option or a

stock-settled SAR and were not issued upon the net settlement or net exercise of such Option or SAR, (x) delivered to, or withheld by, the Company

to pay the Exercise Price or the withholding taxes due with respect to an Option or SAR, (y) withheld by the Company to cover taxes incurred in

connection with other stock-settled Awards, or (z) repurchased on the open market with the proceeds of an Option exercise. To the extent not

prohibited by applicable law, rule or regulation, Shares delivered or deliverable in connection with any Substitute Award shall not reduce the number

of Shares authorized for grant pursuant to Section 3.1 above.

3.3. Adjustments in Authorized Shares and Awards. In the event of any merger, amalgamation, reorganization, consolidation,

recapitalization, reclassification, stock dividend, bonus issues, extraordinary cash dividend, stock split, reverse stock split, share consolidation or

subdivision, spin-off, split-off or similar transaction or other change in corporate structure affecting the Shares, such adjustments and other

substitutions shall be made to the Plan and to Awards as the Committee deems equitable or appropriate, including, without limitation, such

adjustments in the aggregate number, class and kind of securities that may be delivered, in the aggregate or to any Participant, in the number, class,

kind and option or Exercise Price of securities subject to outstanding Awards as the Committee may determine to be appropriate; provided, however,

that the number of Shares subject to any Award shall always be a whole number and further provided that in no event may any change be made to

an ISO which would constitute a modification within the meaning of Code Section 424(h)(3). Moreover, notwithstanding anything in the Plan to the

contrary, an adjustment to an Award may not be made in a manner that would result in adverse tax consequences under Section 409A.

Article 4. Eligibility

performance evaluations.

5.4. Settlement of Restricted Stock Units; Lapse of Restrictions on Restricted Stock. Earned RSUs shall be settled in a lump sum

on or as soon as practicable after the date(s) set forth in the Award Agreement. The Committee may settle earned RSUs in cash, Shares, or a

so provides in an Award Agreement, it may be deferred in accordance with applicable law, to a later date. The Committee may also permit a

Participant to defer payment of Shares related to a RSU or Restricted Stock provided that the terms of the RSU or Restricted Stock and any deferral

level of attainment that shall determine the number of Performance Units or Performance Shares granted, issued, retainable or vested, (d) such

terms and conditions regarding the grant, vesting and forfeiture of the Performance Units or Performance Shares and (e) such other terms and

conditions as may be appropriate.

6.3. Earning of Performance Units or Performance Shares. After completion of an applicable Performance Period, the holder of

Performance Units or Performance Shares shall be entitled to receive a payout with respect to the Performance Units or Performance Shares earned

Article 7. Stock Options and Stock Appreciation Rights

7.1. Award of Options and Stock Appreciation Rights. Subject to Article 4, the Committee may grant Options, SARs or a

combination thereof, to an Employee or Director with such terms and provisions that the Committee shall determine.

7.2. Terms of Options and Stock Appreciation Rights. Each Award of Options or SARs shall be subject to an Award Agreement that

shall set forth (a) the term or duration of the Options or SARs, (b) the number of Shares subject to the Options or SARs, (c) the Exercise Price, (d)

the Exercise Period and (e) such other terms and conditions as may be appropriate. The Committee may grant Options in the form of ISOs, NQSOs

or a combination thereof. Each Award Agreement also shall specify whether the Options are intended to be an ISO or a NQSO.

7.3. Duration of Options and SARs. Each Option or SAR shall expire at such time as the Committee shall determine at the time the

Award is granted; provided, however, that no Option or SAR shall be exercisable later than the tenth (10th) anniversary of its date of grant.

7.4. Exercise of and Payment for Options and SARs. Options and SARs shall be exercisable at such times and be subject to such

terms and conditions as the Committee shall approve, which need not be the same for each Award or for each Participant. Options and SARs shall

be exercised by the delivery of a written notice of exercise to the Company or its designated agent, setting forth the number of Shares to be

exercised with respect to the Options or SARs, and, in the case of Options, accompanied by full payment for the Shares.

The Exercise Price upon exercise of any Option shall be payable to the Company in full under such methods as are authorized by the

Committee, in its sole discretion, including, without limitation: (a) in cash or its equivalent, (b) by tendering, either by actual or constructive delivery,

previously acquired Shares having an aggregate Fair Market Value at the time of exercise equal to the Exercise Price, (c) by net Share settlement or

similar procedure involving the cancellation of a portion of the Option representing Shares with an aggregate Fair Market Value at the time of

exercise equal to the Exercise Price or (d) by any combination thereof. To the extent not prohibited by Section 402 of the Sarbanes-Oxley Act of

2002, the Committee also may allow cashless exercise as permitted under Federal Reserve Board’s Regulation T, subject to applicable securities

law restrictions, or by any other means which the Committee determines to be consistent with the Plan’s purpose and applicable law.

As soon as practicable after receipt of a written notification of exercise of an Option or SAR and provisions for full payment for an

Option, the Company shall issue to the Participant an appropriate number of Shares based upon the number of Shares purchased under the Option

or SAR.

Upon exercise of a SAR, a Participant shall be entitled to receive payment from the Company in an amount equal to the product of:

(a) the excess of (i) the Fair Market Value of a Share on the date of exercise over (ii) the Exercise Price of the SAR, multiplied by (b) the number of

Shares with respect to which the SAR is exercised. At the discretion of the Committee, payment upon the exercise of a SAR may be in cash, in

Shares of equivalent value or in a combination thereof. The Committee’s determination regarding the form of SAR payout shall be set forth in an

applicable Award Agreement.

7.5. Automatic Exercise. The Committee may provide that, in the event that (i) an Option or SAR is not exercised or settled by the

last day of the Exercise Period, (ii) the Participant is legally precluded from otherwise exercising such Option or SAR before the last day of the

Exercise Period due to legal restrictions or Company policy (including policies on trading in Shares), and (iii) the Exercise Price of such Option or

SAR is below the Fair Market Value of a Share on the last day of the Exercise Period, as determined by the Committee, then the Option or SAR may

be deemed exercised on such date, with no action required on the part of the Participant, with a spread equal to the Fair Market Value of the Shares

subject to the Award on such date minus the Exercise Price for those Shares, unless the Participant notifies the Company in writing prior to such

automatic exercise. The resulting proceeds net of any required tax withholding and any applicable costs shall be paid to the Participant or the

Participant’s legal representative.

7.6. No Repricing. Notwithstanding anything in this Plan to the contrary and subject to Section 3.3, without the prior approval of the

shareholders of the Company, the Committee will not amend or replace any previously granted Option or SAR in a transaction that constitutes a

“repricing,” including, but not limited to: (i) the reduction, directly or indirectly, in the per-share Exercise Price of an outstanding Option or SAR by

amendment, cancellation or substitution; (ii) any action that is treated as a repricing under generally accepted accounting principles; (iii) at any time

when the per-share Exercise Price of an outstanding Option or SAR is above the Fair Market Value of a Share, canceling (or accepting the surrender

130 2025 ONEOK, Inc. Proxy Statement

Appendix A: ONEOK, Inc. 2025 Equity Incentive Plan

of) an Option or SAR in exchange for another Option, SAR or other equity security or cash; and (iv) any other action that is treated as a repricing by

the rules or regulations of the New York Stock Exchange.

7.7. Incentive Stock Options.

(a) Additional Requirements. The Exercise Price of an ISO shall be fixed by the Committee at the time of grant or shall

be determined by a method specified by the Committee at the time of grant, but in no event shall the Exercise Price be less than the minimum

Exercise Price specified in Section 7.6. No ISO may be issued to any individual who, at the time the ISO is granted, owns stock possessing more

than 10% of the total combined voting power of all classes of stock of the Company or any of its Subsidiaries, unless (i) the Exercise Price

determined as of the grant date is at least 110% of the Fair Market Value on the date of grant of the Shares subject to such ISO and (ii) the ISO is

not exercisable more than five years from the date of grant thereof. No Participant shall be granted any ISO which would result in such Participant

receiving a grant of ISO that would have an aggregate Fair Market Value in excess of $100,000, determined as of the time of grant, that would be

exercisable for the first time by such Participant during any calendar year. Any grants in excess of this limit shall be treated as NQSOs. No ISO may

be granted under the Plan after the tenth anniversary of the Effective Date. The terms of any ISO granted under the Plan shall comply in all respects

with the provisions of Code Section 422, or any successor provision thereto, as amended from time to time.

(b) Participant Notice Requirement. The Participant must notify the Company in writing within thirty (30) days after any

disposition of Shares acquired pursuant to the exercise of an ISO within two years from the grant date or one year from the exercise date. The

Participant must also provide the Company with all information that the Company reasonably requests in connection with determining the amount

and character of Participant’s income, the Company’s deduction, and the Company’s obligation to withhold taxes or other amounts incurred by

reason of a disqualifying disposition.

Article 8. Other Awards

Subject to limitations under applicable law, the Committee may grant such Other Awards to Employees or Directors that may be

denominated or payable in cash or Shares, valued in whole or in part by reference to, or otherwise based on, or related to, Shares as deemed by the

Committee to be consistent with the purposes of the Plan. The Committee may also grant Shares as a bonus, or may grant Other Awards in lieu of

obligations of the Company or a Subsidiary to pay cash or deliver other property under the Plan or under other plans or compensatory arrangements,

including the payment of cash based on Performance Goals or other criteria. Other Awards may include dividend equivalents that are converted into

Shares in connection with awards granted under this Plan or other equity plans of the Company. The terms and conditions applicable to such Other

Awards shall be determined from time to time by the Committee and set forth in an applicable Award Agreement.

Article 9. Director Stock Awards

9.1. General. Subject to the limit set forth in Section 10.2, each Director Participant shall receive such portion of his or her Director

Fees in Common Stock as shall be established from time to time by the Board, with the remainder of such Director Fees to be payable in cash or in

Common Stock as elected by the Director Participant in accordance with Section 9.2. The Board or the Compensation Committee shall approve all

Director Stock Awards granted under the Plan.

9.2. Director Election. Each Director Participant shall have an opportunity to elect to have the remaining portion of his or her

Director Fees paid in cash or shares of Common Stock or a combination thereof. Shares delivered pursuant to such election shall be issued under

the Plan. Except for the initial election pursuant to the adoption of the Plan, or the Director’s election to the Board, any such election shall be made in

writing and must be made at least thirty (30) days before the beginning of the Plan Year in which the services are to be rendered giving rise to such

Director Fees and may not be changed thereafter except by timely written election as to Director Fees for services to be rendered in a subsequent

Plan Year. In the absence of such an election, such remaining portion of the Director Fees of a Director shall be paid entirely in cash.

9.3. Share Awards. The number of shares of Common Stock to be paid and distributed to a Director as a Director Stock Award

under the provisions of Sections 9.1 and 9.2, shall be determined by dividing the dollar amount of his or her Director Fees (which the Board has

established, and/or such Director has elected) to be paid in Common Stock on any payment date by the Fair Market Value of a share of Common

Stock on that date. Except as may otherwise be directed by the Committee, in its sole discretion, the payment and distribution of such shares to a

Director shall be on or within five days after the date such Director Fees would otherwise have been paid to him or her in cash.

Article 10. General Provisions Applicable to Awards

10.1. Limits on Incentive Stock Options. No more than an aggregate of 16,870,000 Shares may be issued under ISOs, subject to

adjustment as described in Section 3.3.

10.2. Limitation on Director Compensation. The maximum number of Shares subject to Awards that may be granted under this Plan

or otherwise during any one year to a Director, taken together with any cash fees paid by the Company to such Director during such year for service

on the Board, will not exceed $1,000,000 in total value (calculating the value of any such Awards based on the grant date fair value of such Award).

10.3. Performance-Based Awards. Unless the Committee determines otherwise, the following provisions shall apply to performance-

based Awards.

2025 ONEOK, Inc. Proxy Statement 131

Appendix A: ONEOK, Inc. 2025 Equity Incentive Plan

(a) The applicable Performance Goals and Performance Period will be established by the Committee. Each recipient of

a performance-based Award will be assigned a target amount of Shares or cash payable if Performance Goals are achieved. Achievement of the

Performance Goals and other material conditions and payment of an Award granted with Performance Goals shall be determined by the Committee.

An Award may provide for payment greater than the target amount if performance exceeds the specified Performance Goals. The Committee may

retain discretion to increase or decrease the amount payable pursuant to such Awards, as the Committee determines.

(b) The Performance Goals may be described in terms of objectives related to the individual Participant or objectives

that are Company-wide or related to a Subsidiary, business unit, division, segment, product line, or function or combination thereof and may be

measured on an absolute or cumulative basis or on the basis of percentage of improvement over time, and may be measured in terms of Company

performance (or performance of the applicable Subsidiary, business unit, division, segment, product line, or function or combination thereof) or

measured relative to a market index, selected peer companies or one or more operating units, divisions, acquired businesses, minority investments,

partnerships or joint ventures thereof. The Performance Goals selected by the Committee in connection with the grant of Awards may include one or

more of the following measures or any such other measures as the Committee determines: earnings, earnings growth, earnings per share, stock

Performance Goals need not be based upon an increase or positive result under a particular business criterion and could include, for example,

maintaining the status quo or limiting economic losses (measured, in each case, by reference to specific business criteria). Performance Goals shall

apply with respect to such Performance Period as the Committee may specify. Any applicable Performance Goals shall be applied and interpreted in

the discretion of the Committee.

accepted accounting principles consistently applied on a Subsidiary, business unit, division, segment, product line, function or consolidated basis or

any combination thereof. Notwithstanding the foregoing, the Committee may adjust the Performance Goals and the method of calculating the

attainment of the Performance Goals to take into account events that occur during a Performance Period, including but not limited to: (i) asset write-

downs; (ii) litigation or claim judgments or settlements; (iii) the effect of changes in tax laws, accounting principles or other laws or provisions

affecting reported results; (iv) charges for any reorganization and restructuring programs; (v) any extraordinary, unusual, or other infrequently

occurring items as described in Accounting Standards Codification 225-20-20 (as amended by Accounting Standards Update No. 2015-01) or in the

management’s discussion and analysis of financial condition and results of continuing operations appearing in the Company’s annual report to

shareholders for the applicable year; (vi) the impact of mergers, acquisitions or divestitures; (vii) foreign exchange gains and losses; and (viii) gains

or losses on asset sales.

10.4. Restrictions on Transfers of Awards. Except as provided by the Committee, no Award and no right under any such Award,

shall be assignable, alienable, saleable, or transferable by a Participant otherwise than by will or by the laws of descent and distribution provided,

however, that, if so determined by the Committee, a Participant may, in the manner established by the Committee, designate a Beneficiary or

Beneficiaries to exercise the rights of the Participant with respect to any Award other than an ISO upon the death of the Participant. Each Award, and

each right under any Award, shall be exercisable, during the Participant’s lifetime, only by the Participant or, if permissible under applicable law, by

the Participant’s guardian or legal representative. No Award and no right under any such Award, may be pledged, alienated, attached, or otherwise

encumbered, including pursuant to any order or judgment in a domestic relations proceeding, official marital settlement agreement or other divorce or

separation instrument, and any purported pledge, alienation, attachment, or encumbrance thereof shall be void and unenforceable against the

Company or any Subsidiary.

10.5. Restrictions on Transfers of Shares. The Committee may impose such restrictions on any Shares acquired pursuant to an

Award as it may deem advisable, including, without limitation, restrictions to comply with applicable Federal securities laws, with the requirements of

any stock exchange upon which such Shares are then listed and with any blue sky or state securities laws applicable to such Shares.

10.6. Additional Restrictions on Awards and Shares. Either at the time an Award is granted or by subsequent action, the Committee

may, but need not, impose such restrictions, conditions or limitations as it determines appropriate on the Award, any Shares issued under an Award,

or both, including, without limitation, (a) restrictions under an insider trading policy, (b) any share retention guidelines, minimum holding requirements

and other restrictions designed to delay or coordinate the timing and manner of sales, (c) restrictions as to the use of a specified brokerage firm for

receipt, resales or other transfers of such Shares, (d) restrictions relating to a Participant’s activities following termination of employment or service,

including but not limited to, competition against the Company, disclosure of Company confidential information, and solicitation of Company

employees and/or customers, and (e) other policies either existing at the time an Award is granted or subsequently adopted and implemented by the

Board, as such other policies may be amended from time to time.

10.7. Shareholder Rights ; Dividend Equivalents. Except as provided in the Plan or an Award Agreement, no Participant shall receive

any Shares in connection with an Award nor be afforded any of the rights of a shareholder unless and until such Participant has satisfied all

requirements for exercise or vesting of the Award pursuant to its terms, the Shares have actually been issued, restrictions imposed on the Shares, if

132 2025 ONEOK, Inc. Proxy Statement

Appendix A: ONEOK, Inc. 2025 Equity Incentive Plan

any, have been removed, and the Shares are entered upon the records of a duly authorized transfer agent of the Company. The recipient of an

Award (other than Options and SARs) may be entitled to receive Dividend Equivalents, and the Committee may provide that such amounts (if any)

shall be deemed to have been reinvested in additional Shares or otherwise reinvested and subject to vesting and forfeiture to the same extent as the

underlying Award; provided, however, that Dividend Equivalents shall only become payable if and to the extent the underlying Award vests,

regardless of whether or not vesting is contingent upon continued employment, the achievement of Performance Goals, or both.

10.8. Termination of Employment or Service. Each Award Agreement shall set forth the terms relating to the treatment of an Award

in the event of a Participant’s termination of employment or service, including, without limitation, the extent to which the right to vest, exercise or

receive payout of an Award may continue following termination of the Participant’s employment or service with the Company and its Subsidiaries,

including due to death or Disability, and any forfeiture provisions. Such provisions shall be determined by the Committee in its discretion, shall be

included in the Award Agreement applicable to a Participant, need not be uniform among all Awards or among all Participants and may reflect

distinctions based on the reasons for termination of employment or service.

10.9. Effect of Change in Status. The Committee shall have the discretion to determine the effect upon an Award, in the case of (i)

any individual who is employed with, or engaged by, an entity that ceases to be a Subsidiary, (ii) any leave of absence approved by the Company or

a Subsidiary, (iii) any transfer between locations of employment with the Company or a Subsidiary or between any Subsidiaries (iv) any change in

the Participant’s status from an Employee to a consultant or Director, or vice versa, and (v) at the request of the Company or a Subsidiary, any

Participant who becomes employed by any partnership, joint venture, corporation or other entity not meeting the requirements of a Subsidiary.

Article 11. Change in Control

11.1. Awards Assumed or Replaced by Successor. Unless the Committee provides otherwise prior to the Change in Control or in an

Award Agreement, upon the occurrence of a Change in Control in which the acquiring or surviving company in the transaction assumes or continues

outstanding Awards or provides equivalent awards of substantially the same value, the Committee shall measure performance as of the date of the

Change in Control for all outstanding Awards of Performance Units, Performance Shares and other performance-based Awards granted prior to the

Change in Control based on the greater of (x) the payout at the target number of Performance Units, Performance Shares and other performance-

based Awards granted for the Performance Period and (y) the payout based upon the actual performance level attained as of the date of the Change

in Control, in each case, after giving effect to the accumulation of Dividend Equivalents, and the Participant shall continue to vest in such Awards

based on continued service. Unless the Committee provides otherwise prior to the Change in Control or in an Award Agreement, if a Participant’s

employment with the Company or a Subsidiary is terminated without Cause or by the Participant for Good Reason, in each case at any time within

two (2) years after the Change in Control, the following provisions shall apply with respect to such assumed, continued or equivalent awards:

(a) Any Period of Restriction and other restrictions imposed on RSUs and Restricted Stock granted prior to the Change

in Control shall be deemed to have expired, and RSUs shall be paid in cash or in Shares, as determined by the Committee;

(b) With respect to all outstanding Awards of Performance Units, Performance Shares and other performance-based

Awards granted prior to the Change in Control, the Award shall be paid at the greater of (x) the payout at the target number of the Performance

Units, Performance Shares and other performance-based Awards granted for the entire Performance Period or (y) the payout based upon the actual

performance level attained as of the date of the Change in Control, in each case, after giving effect to the accumulation of Dividend Equivalents.

Payment shall be made in cash or in Shares, as determined by the Committee;

Dividend Equivalents to the date of payment) not yet paid out shall be paid out immediately, in cash or in stock, as determined by the Committee;

(d) All outstanding and unvested Options and SARs granted prior to the Change in Control shall become immediately

exercisable, and Awards in the form of NQSOs and SARs shall be exercisable after the date of the Participant’s termination for a period equal to the

lesser of (i) the remaining term of each Award; or (ii) twelve (12) months; and

(e) Any restrictions imposed on any and all outstanding and unvested Other Awards granted prior to the Change in

Control shall be deemed to have expired.

2025 ONEOK, Inc. Proxy Statement 133

Appendix A: ONEOK, Inc. 2025 Equity Incentive Plan

11.2. No Assumption or Replacement of Awards by Successor. Notwithstanding anything herein to the contrary, unless the

Committee provides otherwise prior to the Change in Control or in an Award Agreement, in the event of a Change in Control in which the acquiring or

surviving company in the transaction does not assume or continue outstanding Awards upon the Change in Control or provide equivalent awards of

substantially the same value, all Awards that are not assumed, continued or replaced with such equivalent awards shall, immediately prior to the

Change in Control, be treated as follows upon the Change in Control:

(a) Any Period of Restriction and other restrictions imposed on RSUs and Restricted Stock shall be deemed to have

expired, and RSUs shall be paid in cash or in Shares, as determined by the Committee;

(b) With respect to all outstanding Awards of Performance Units, Performance Shares and other Awards type that is

earned based upon the Company’s attainment of Performance Goals the Committee (i) shall determine the greater of (x) the payout at the target

number of Performance Units, Performance Shares and other such Award type granted for the entire Performance Period and (y) the payout based

upon the actual performance level attained as of the date of the Change in Control, in each case, after giving effect to the accumulation of Dividend

Equivalents, and (ii) shall pay to the Participant the greater of such amounts. Payment shall be made in cash or in Shares, as determined by the

Committee;

Dividend Equivalents to the date of payment) not yet paid out shall be paid out immediately, in cash or in stock, as determined by the Committee;

(d) Any and all outstanding and unvested Options and SARs shall become immediately exercisable and the Committee

will notify Participants in writing that such Awards will be exercisable for a period of time determined by the Committee in its discretion and such

Awards will terminate upon the expiration of such period. Notwithstanding the foregoing, to the extent an Option or SAR is not exercised, upon the

Change in Control, the Committee may, in its sole discretion, cancel such Award in exchange for an amount equal to the difference between the

Exercise Price and the then Fair Market Value of the Shares covered thereby provided that if the Exercise Price is above the Fair Market Value of the

Shares, the Options or SARs shall be cancelled without payment of consideration therefor; and

(e) Any restrictions imposed on any and all outstanding and unvested Other Awards shall be deemed to have expired.

11.3. Assumption of Awards by the Company. The Company, from time to time, may substitute or assume outstanding awards

granted by another company, whether in connection with an acquisition of such other company or otherwise, by either; (a) granting a Substitute

Award; or (b) assuming such award as if it had been granted under this Plan if the terms of such assumed award could be applied to an Award

granted under this Plan.

11.4. Other. For the avoidance of doubt, nothing herein shall require the acquiring or surviving company in a Change in Control to

assume all Awards previously granted under the Plan or to provide equivalent awards of substantially the same value. Notwithstanding anything in

this Plan or any other Company plan or arrangement to the contrary, no tax gross up shall be provided with respect to tax consequences of Awards

under Section 280G or 4999 of the Code.

11.5. Termination in Connection with a Change in Control. Notwithstanding anything in this Plan to the contrary, if an Employee’s

employment is terminated by the Company without Cause prior to the date of a Change in Control and the Employee reasonably demonstrates that

the termination (1) was at the request of a third party who has indicated an intention or taken steps reasonably calculated to effect a Change in

Control or (2) otherwise arose in connection with, or in anticipation of, a Change in Control which has been threatened or proposed at the time of the

termination, such termination shall be deemed to have occurred after a Change in Control for purposes of this Plan, provided a Change in Control

shall actually have occurred.

Article 12. Tax Withholding

The Company or a Subsidiary, as appropriate, may require any individual entitled to receive a payment of an Award to remit to the

Company, prior to payment, an amount sufficient to satisfy any applicable tax withholding requirements. In the case of an Award payable in Shares,

the Company or a Subsidiary, as appropriate, may permit or require a Participant to satisfy, in whole or in part, the obligation to remit taxes by

directing the Company to withhold Shares that would otherwise be received by the individual, or may repurchase Shares that were issued to the

Participant, the number of Shares which may be so withheld or surrendered shall not exceed the maximum amount of tax that may be required to be

withheld by law (or such other amount as may be permitted while still avoiding classification of the Award as a liability for accounting purposes), in

accordance with applicable law and pursuant to any rules that the Company may establish from time to time. With respect to an Award held by any

Section 16 Person, any such share withholding must be specifically approved by the Committee as the method used to satisfy the tax withholding

obligation or such share withholding procedure must otherwise satisfy the requirements of SEC Rule 16b-3. The Company may establish procedures

to allow Participants to satisfy such withholding obligations through a net share settlement procedure or the withholding of Shares subject to the

applicable Award. The Company or a Subsidiary, as appropriate, shall also have the right to deduct from all cash payments made to a Participant

(whether or not the payment is made in connection with an Award) any applicable taxes required to be withheld with respect to payments under the

Plan. With respect to any Award that is subject to Section 409A, the Company or a Subsidiary may, to the extent permitted by Section 409A, permit

the acceleration of the time or schedule of a payment to pay FICA taxes, and any related income tax at source imposed by Code Section 3401 on

the FICA taxes.

shall notify the Claimant of the resolution of the Claim within 90 days after receipt of the Claim; provided, however, if the Claims Administrator

13.4. Notice of Denial. If a Claim is wholly or partially denied, the notice of denial shall contain (i) the specific reason or reasons for

denial of the Claim, and (ii) specific references to the pertinent Plan provisions upon which the denial is based. Except as provided in Section 13.5,

the Claimant with respect to a Claim, must be resolved by arbitration in the manner described in this Section. This agreement to arbitrate shall be

specifically enforceable. A party may apply to a state or federal court located in Tulsa, Oklahoma for interim, injunctive or conservatory relief in aid of

arbitration, including without limitation a proceeding to compel arbitration. If the arbitration provisions herein are determined by any court to be

unenforceable, any further legal action must be filed only in a state or federal court located in Tulsa, Oklahoma within the time limits set forth in

Participant’s grants, agree to waive any right to sue in court or to pursue any other legal right or remedy that might otherwise be available in

connection with the resolution of the Claim.

(e) Enforceability . Judgment upon any award entered by an arbitrator may be entered in any court having jurisdiction

over the parties.

(f) Waiver of Class, Collective, and Representative Actions . Any Claim shall be heard without consolidation of such

representative or consolidated action arising out of or relating to any Claim, and Participants agree that any Claim may only be initiated or maintained

and decided on an individual basis.

(g) Standard of Review . Any decision of an Arbitrator on a Claim shall be limited to determining whether the Claim

Administrator’s decision or action was arbitrary or capricious or was unlawful. The Arbitrator shall adhere to and apply the deferential standard of

review set out in Conkright v. Frommert , 559 U.S. 506 (2010), Metropolitan Life Insurance Co. v . Glenn , 554 U.S. 105 (2008), and Firestone Tire and

(h) General Procedures .

(i) Arbitration Rules . The arbitration hearing will be conducted under the AAA Commercial Arbitration Rules

(as amended or revised from time to time by AAA) (hereinafter the “AAA Rules”), before one AAA arbitrator who is from the Large, Complex Case

Panel and who has experience with matters involving executive compensation and equity compensation plans. The AAA Rules and the terms and

procedures set forth here may conflict on certain issues. To the extent that the procedures set forth here conflict with the AAA Rules, the procedures

set forth here shall control and be applied by the arbitrator. Notwithstanding the amount of the Claim, the Procedures for Large, Complex Commercial

Disputes shall not apply.

(ii) Substantive Law . The arbitrator shall apply the substantive law (and the laws of remedies, if applicable),

of Oklahoma or federal law, or both, depending upon the Claim. Except to the extent required by applicable law, all arbitration proceedings,

decisions, and awards shall be kept strictly confidential and shall not be disclosed by the arbitrator, the Company, or the Claimant.

(iii) Authority . The arbitrator shall have jurisdiction to hear and rule on prehearing disputes and is authorized

to hold prehearing conferences by telephone or in person as the arbitrator deems necessary. The arbitrator will have the authority to hear a motion to

dismiss and/or a motion for summary judgment by any party and in doing so shall apply the standards governing such motions under the Federal

Rules of Civil Procedure.

(iv) Pre-Hearing Procedures . Each party may take the deposition of not more than one individual and the

expert witness, if any, designated by another party. Each party will have the right to subpoena witnesses in accordance with the Arbitration Act.

Additional discovery may be had only if the arbitrator so orders, upon a showing of substantial need.

(v) Fees and Costs . Administrative arbitration fees and arbitrator compensation shall be borne equally by

the parties, and each party shall be responsible for its own attorney’s fees, if any; provided, however, that the Committee will authorize payment by

the Company of all administrative arbitration fees, arbitrator compensation and attorney’s fees if the Committee concludes that a Claimant has

substantially prevailed on his or claims. Unless prohibited by statute, the arbitrator shall assess attorney’s fees against a party upon a showing that

such party’s claim, defense or position is frivolous, or unreasonable, or factually groundless. If either party pursues a Claim by any means other than

those set forth in this Article, the responding party shall be entitled to dismissal of such action, and the recovery of all costs and attorney’s fees and

losses related to such action, unless prohibited by statute.

(i) Interstate Commerce and the Federal Arbitration Act . The Company is involved in transactions involving interstate

commerce, and the employee’s employment with the Company involves such commerce. Therefore, the Arbitration Act will govern the interpretation,

enforcement, and all judicial proceedings regarding the arbitration procedures in this Section.

14.1. Gender and Number. Except where otherwise indicated by the context, any masculine term used herein also shall include the

feminine, the plural shall include the singular and the singular shall include the plural.

14.2. Headings and Severability . The headings of Articles and Sections herein are included solely for convenience of reference and

shall not affect the meaning of any of the provisions of the Plan. In the event any Plan provision, including, without limitation, any provisions under

Article 13, shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining Plan provisions, and the Plan shall be

construed and enforced as if the illegal or invalid provision had not been included.

14.3. Successors . All Company obligations with respect to Awards, shall be binding on any successor to the Company, whether the

existence of such successor is the result of a direct or indirect purchase, merger, consolidation or otherwise, of all or substantially all of the business

or assets of the Company.

14.4. No Right to Employment or Engagement . Nothing in the Plan shall interfere with or limit in any way the right of the Company to

terminate any Participant’s employment or engagement at any time, for any reason or no reason in the Company’s discretion, nor confer upon any

Participant any right to continue in the employ or service of the Company or any Subsidiary.

14.5. Beneficiary Designation . To the extent permitted by the Committee, each Participant may, from time to time, name any

Beneficiary or Beneficiaries (who may be named contingently or successively) to whom any Plan benefit is to be paid in case of his or her death

before he or she receives any or all of such benefit. Each such designation shall revoke all prior designations by the same Participant, shall be in a

form prescribed by the Committee, and will be effective only when filed by the Participant in writing with the Committee during the Participant's

lifetime. In the absence of any such designation, benefits remaining unpaid at the Participant's death shall be paid to the Participant's estate. The

spouse of a married Participant domiciled in a community property jurisdiction shall join any designation of Beneficiary or Beneficiaries other than

136 2025 ONEOK, Inc. Proxy Statement

Appendix A: ONEOK, Inc. 2025 Equity Incentive Plan

14.7. Loans Prohibited . The Committee shall not, without prior approval of the Company’s shareholders, grant any Award that

provides for the making of a loan or other extension of credit, directly or indirectly, by the Company or Plan to an Employee, Participant, officer of the

Company or any other person in connection with the grant, award or payment of such Award.

14.8. Requirements of Law . The making of Awards and the issuance of Shares shall be subject to all applicable laws, rules and

regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. The Company shall not be

required to issue or deliver any certificates or make any book entries evidencing Shares pursuant to the exercise or vesting of any Award, unless and

until the Board or the Committee has determined, with advice of counsel, that the issuance of such Shares is in compliance with all applicable laws,

regulations of governmental authorities and, if applicable, the requirements of any exchange on which the Shares are listed or traded, and the

Shares are covered by an effective registration statement or by an applicable exemption from registration. In addition to the terms and conditions

provided in the Plan, the Board or the Committee may require that a holder make such reasonable covenants, agreements, and representations as

the Board or the Committee deems advisable in order to comply with any such laws, regulations, or requirements.

14.9. Securities Law Compliance . Plan transactions are intended to comply with all applicable conditions of the Federal securities

laws. To the extent any Plan provision or action by the Committee fails to so comply, it shall be deemed null and void, to the extent permitted by law

and deemed advisable by the Committee.

14.10. Code Section 409A Compliance . The parties intend that Plan payments and benefits comply with Section 409A to the extent it

applies or an exemption therefrom, and, accordingly, to the maximum extent permitted, the Plan shall be interpreted and be administered to be in

compliance therewith. Any payments described in the Plan that are due within the “short-term deferral period” as defined in Section 409A shall be

paid prior to the 15th day of the third month of the calendar year immediately following the calendar year in which any applicable restrictions lapse

and shall not be treated as deferred compensation unless applicable law requires otherwise. Notwithstanding anything to the contrary in the Plan:

(i) no payment or distribution under this Plan that constitutes an item of deferred compensation under Section 409A and becomes payable by reason

of a Participant’s termination of employment or service with the Company will be made to such Participant until such Participant’s termination of

employment or service constitutes a “separation from service” as defined in Section 409A; and (ii) to the extent required in order to comply with

Section 409A, amounts that would otherwise be payable and benefits that would otherwise be provided during the six (6) month period immediately

following the Participant’s termination of employment shall instead be paid on the first business day after the date that is six (6) months following the

Participant’s separation from service (or upon the Participant’s death, if earlier). In addition, for Plan purposes, each amount to be paid or benefit to

be provided to the Participant pursuant to the Plan, which constitute deferred compensation subject to Section 409A, shall be construed as a

separate identified payment for purposes of Section 409A. For any Plan payment that constitutes “non-qualified deferred compensation” under

Section 409A, to the extent required to comply with Section 409A, a Change in Control shall be deemed to have occurred with respect to such

payment only if a change in the ownership or effective control of the Company or a change in ownership of a substantial portion of the assets of the

Company shall also be deemed to have occurred under Section 409A. The Company makes no representation that any or all of the payments or

benefits described in this Plan will be exempt from or comply with Section 409A and makes no undertaking to preclude Section 409A from applying

to any such payment. A Participant shall be solely responsible for the payment of any taxes and penalties incurred under Section 409A.

14.11. Effect on Other Benefits . No payment pursuant to the Plan shall be taken into account in determining any benefits under any

pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company or any affiliate except to the extent

otherwise expressly provided in writing in such other plan or an agreement thereunder.

14.12. Unfunded Plan . The Plan is intended to be an unfunded plan for incentive compensation. With respect to any payments not yet

made to a holder pursuant to an Award, nothing contained in the Plan or any Award Agreement shall give the holder any rights that are greater than

those of a general creditor of the Company or any affiliate.

14.13. Recoupment . Notwithstanding anything in the Plan to the contrary, all Awards granted under the Plan, all Shares issued with

respect to Awards, any payments made under the Plan and any gains realized upon exercise or settlement of an Award shall be subject to the terms

of any applicable clawback or recoupment policies approved by the Board or the Committee, as in effect from time to time, whether approved before

or after the date Awards are granted under the Plan (as applicable, a “Clawback Policy”). In the event of a clawback, recoupment or forfeiture event

under an applicable Clawback Policy, the amount required to be clawed back, recouped or forfeited pursuant to such policy shall be deemed not to

have been earned under the terms of the Plan and Award Agreement, and the Company shall be entitled to recover the amount specified under the

policy to be clawed back, recouped or forfeited.

14.14. Award Agreement . In the event of any conflict or inconsistency between the Plan and any Award Agreement, the Plan shall

govern and the Award Agreement shall be interpreted to minimize or eliminate any such conflict or inconsistency.

14.15. Plan Acceptance . By accepting any benefits under the Plan, each Participant, and each person claiming under or through a

Participant shall be conclusively deemed to have indicated his or her acceptance and ratification of, and consent to, all provisions of the Plan and

any action or decision under the Plan by the Company, its agents and employees, and the Board of Directors and the Committee, specifically

including the Plan’s mandatory arbitration provision. Acceptance of an Award may be made in a writing signed by the Participant (including

electronically); provided however in the absence of a signed acceptance, a Participant shall be deemed to have accepted an Award as of the grant

2025 ONEOK, Inc. Proxy Statement 137

Appendix A: ONEOK, Inc. 2025 Equity Incentive Plan

date in the absence of a specific manifestation from the Participant within 60 days of the grant date indicating that the Participant has rejected

the Award.

14.16. Governing Law . To the extent not preempted by Federal law, the Plan, the Award Agreements and all agreements thereunder,

shall be construed in accordance with, and subject to, the laws of the State of Oklahoma applicable to contracts made and to be entirely performed in

Oklahoma and wholly disregarding any choice of law provisions or conflict of law principles that might otherwise be contrary to this express intent.

Article 15. Effective Date, Termination and Amendment

15.1. Effective Date . The Effective Date of the Plan shall be the date of approval by the Company’s shareholders of the Plan.

15.2. Termination . The Plan shall terminate on the day immediately before the tenth anniversary of the Effective Date. The Board

may, in its sole discretion and at any earlier date, terminate the Plan. In no event may an Award be granted under the Plan on or after the tenth

(10th) anniversary of the Effective Date. Any Awards that are outstanding upon termination of the Plan shall remain in force and effect in accordance

with the terms of the Plan and any applicable Award Agreement.

15.3. Amendment . The Board may at any time and from time to time amend or modify the Plan in whole or in part; provided,

however, that no amendment which requires shareholder approval in order for the Plan to comply with Code Section 422, Section 303A.08 of the

New York Stock Exchange Listed Company Manual, or any other applicable law, regulation or rule, shall be effective unless such amendment shall

be approved by the requisite vote of the shareholders.

15.4. Awards Previously Granted . No termination, amendment or modification of the Plan shall adversely affect in any material way

any outstanding Award, without the written consent of the Participant holding such Award unless such termination, modification or amendment is

required by applicable law and/or the Committee, upon advice of legal counsel, deems the action necessary or advisable to comply with Section

409A. Notwithstanding the foregoing, the Committee may, but shall not be required to, in its sole and absolute discretion, amend Awards to comply

with Section 409A.

Acquisition” means an acquisition by (i) an employee benefit plan (or a trust forming a part thereof) maintained by (A) the Company or (B) any

corporation or other Person of which a majority of its voting power or its voting equity securities or equity interest is owned or controlled, directly or

(b) The individuals who are members of the Board (the “ Incumbent Board ”) on the Effective Date, cease for any reason to

Company’s common shareholders, of any new director was approved by a vote of at least two-thirds of the Incumbent Board, such new director shall,

for purposes of this Agreement, be considered as a member of the Incumbent Board; provided further , however , that no individual shall be

issued (a “ Merger ”), unless such Merger is a “Non-Control Transaction.” A “ Non-Control Transaction ” means a Merger where:

the shareholders of the Company, immediately before such Merger, own directly or indirectly immediately

following such Merger at least fifty percent (50%) of the combined voting power of the outstanding voting

securities of (x) the corporation resulting from such Merger (the “ Successor ”) if fifty percent (50%) or more

Companies, the ultimate Parent Company;

Merger for this purpose or the distribution to the Company’s shareholders of the stock of a Related Entity or any other assets); or

Notwithstanding the foregoing, a Change in Control shall not be deemed to occur, solely because any Person (the “ Subject Person ”) acquired

Beneficial Ownership of more than the permitted amount of the then outstanding Shares or Voting Securities if such acquisition occurs as a result of

the acquisition of Shares or Voting Securities by the Company which, by reducing the number of Shares or Voting Securities then outstanding,

increases the proportional number of shares Beneficially Owned by the Subject Person, provided that if a Change in Control would occur (but for the

operation of this subparagraph) as a result of the acquisition of Shares or Voting Securities by the Company, and after such share acquisition by the

Company, the Subject Person becomes the Beneficial Owner of any additional Shares or Voting Securities which increases the percentage of the

then outstanding Shares or Voting Securities Beneficially Owned by the Subject Person, then a Change in Control shall occur.

With respect to any Award that is subject to Section 409A and payment is to be accelerated in connection with the Change in Control,

solely for purposes of determining the timing of payment, no event(s) set forth in clauses (a), (b) or (c) above shall constitute a Change in Control for

which renders the Participant incapable of continuing the Participant’s usual or customary employment or service with the Participant’s employer or

service recipient for a period of not less than six consecutive months. Disability of a Participant shall be determined pursuant to and in accordance

with the procedures for determining eligibility for disability benefits under the long term disability plan of the Company or Subsidiary, if any. If there is

no Company long term disability plan, then the Committee shall determine Disability. Notwithstanding the previous two sentences, with respect to an

Award that is subject to Section 409A where the payment or settlement of the Award will accelerate upon termination of employment or service as a

result of the Participant’s Disability, solely for purposes of determining the timing of payment, no such termination will constitute a Disability for

purposes of the Plan or any Award Agreement unless such event also constitutes a “disability” as defined under Section 409A.

“Dividend Equivalent” means, with respect to Shares subject to Awards, a right to an amount equal to dividends declared on an equal

number of issued and outstanding Shares.

“Fair Market Value” means the closing sale price as reported on the New York Stock Exchange or other domestic stock exchange for

that date or, if there is no such sale on the relevant date, then on the last previous day on which a sale was reported, unless otherwise determined by

the Committee. If the Common Stock is not listed on a domestic stock exchange, Fair Market Value will be determined by such other method as the

ONEOK, INC.

2025 EMPLOYEE STOCK AWARD PROGRAM

Effective May 21, 2025

ONEOK, Inc. (“ONEOK”) hereby establishes the ONEOK, Inc. 2025 Employee Stock Award Program, as may be amended from time to time

(the “2025 ESAP”), effective as of the date on which ONEOK’s stockholders approve the 2025 ESAP (the “Effective Date”). The 2025 ESAP is

intended to be a successor to the ONEOK Employee Stock Award Program (the “Prior ESAP”). The Prior ESAP terminated as of November 7, 2024,

and no additional grants will be made under the Prior ESAP after such termination date.

Under the terms of this 2025 ESAP, all eligible employees of ONEOK and its direct or indirect subsidiaries (collectively, the “Company”) will

each be awarded, for no monetary consideration, one share of ONEOK’s common stock, par value $0.01 per share (the “Common Stock”) at such

time on or following the Effective Date that the closing price of the Common Stock on the New York Stock Exchange (“NYSE”) attains the next whole

$1.00 increment above the all-time highest closing price of the Common Stock on the NYSE before the Effective Date (the “Base Share Price,” and

the date on which the Base Share Price is attained, the “Initial Benchmark Date”). Subsequently, eligible employees will each be awarded, for no

monetary consideration, one additional share of Common Stock at such time as the closing price of the Common Stock is for the first time, on or after

the Effective Date, at or above each $1.00 increment above the Base Share Price (each such date, together with the Initial Benchmark Date and any

benchmark date for a discretionary award as described below, being a “Benchmark Date”).

In addition, the Board of Directors of ONEOK (the “Board”) may make awards of additional shares of Common Stock under the 2025 ESAP to

eligible employees in its sole discretion in the event that the Board determines that the closing price of Common Stock as of a date specified by the

Board has attained one or more specified price thresholds at or before the date of the award and that the circumstances warrant such an award. In

the event of such an award, eligible employees will each be awarded, for no monetary consideration, one additional share of Common Stock based

on attainment of each such price threshold at such time as the Board deems appropriate. For purposes of the discretionary awards, the “Benchmark

Date” is the date, on or after the Effective Date, on which the Board approves the discretionary awards.

The “closing price” is the last sale price, regular way, of the Common Stock as reported on the principal consolidated transaction system with

respect to securities listed or admitted to trading on the NYSE.

What is the purpose of the 2025 ESAP?

The purpose of the 2025 ESAP is to reward eligible employees for the Common Stock attaining specified price thresholds.

Who will administer the 2025 ESAP?

The Board or Executive Compensation Committee of the Board (the “Executive Compensation Committee") will administer the 2025 ESAP. The

Board and Executive Compensation Committee each have discretion to make determinations with respect to the 2025 ESAP. However, the Board

will make all decisions with respect to the grant of awards under the 2025 ESAP. All determinations of the Board or Executive Compensation

Committee, as applicable, with respect to the 2025 ESAP are final and binding.

The Board or Executive Compensation Committee may delegate administrative duties (but not decisions with respect to the grant of awards) to

any one or more of its members or to members of management, as appropriate. All actions taken by a delegee of the Board or Executive

Compensation Committee pursuant to a valid delegation shall have the same legal effect and shall be entitled to the same deference as if taken by

the Board or Executive Compensation Committee itself. For the avoidance of doubt, the Board may not delegate the decision to grant awards under

the 2025 ESAP, and the Board shall make all award decisions with respect to employees who are subject to Section 16 of the Securities Exchange

Act of 1934, as amended from time to time.

142 2025 ONEOK, Inc. Proxy Statement

Appendix B: ONEOK, Inc. 2025 Employee Stock Award Program

Who is eligible to participate in the 2025 ESAP?

Eligible employees are all persons who are active full-time U.S. employees of the Company, and any full-time employees of the Company who

are on short-term disability, as of the “Eligibility Date” for each issuance under the 2025 ESAP. Only employees working in the U.S. are eligible for

the 2025 ESAP. The “Eligibility Date” shall be the applicable Benchmark Date of each issuance of Common Stock under the 2025 ESAP.

How many shares will employees get?

Each eligible employee will be awarded one share of Common Stock on each Benchmark Date, except for discretionary awards, in which case

each eligible employee will be awarded one share of Common Stock for the attainment of each specified price threshold.

Will employees have to pay any amount to receive shares?

No. Participation in the 2025 ESAP is neither voluntary nor contributory. Accordingly, ONEOK will issue eligible employees shares without

payment by the employees of any purchase price. Each eligible employee will be responsible for the tax withholding that will be made from the

employee’s paycheck based on the value of the stock award that is made to the employee.

When will employees receive shares ?

The shares of Common Stock issued under the 2025 ESAP will be issued by ONEOK’s transfer agent, Equiniti Trust Company, LLC (“EQ”),

and will be deposited to the employee’s account at EQ within a reasonable time after each Benchmark Date. ONEOK will notify all eligible employees

of the Benchmark Date, when each issuance of Common Stock under the 2025 ESAP is to be made, and EQ will provide a confirming statement of

the deposit within a reasonable time.

How will employees receive shares?

All shares issued under the 2025 ESAP will be deposited to the eligible employee’s existing account at EQ in book entry form. If the employee

does not have an account at EQ, an account will be set up for the employee by EQ and the employee’s shares of Common Stock will be deposited to

the employee’s new account.

Can employees transfer shares issued under the 2025 ESAP into ONEOK’s 401(k) Plan, Employee Stock Purchase Plan, or other plan?

No.

How will dividends be paid?

Dividends on the Common Stock are paid when and as declared by the Board. There can be no assurance as to the future declaration or

payment of any dividends. Dividends on any shares in the employee’s account at EQ will be credited to the employee’s EQ account.

What if ONEOK declares a stock split or other corporate event affecting the Common Stock?

In the event of any merger, amalgamation, reorganization, consolidation, recapitalization, reclassification, stock dividend, bonus issues,

extraordinary cash dividend, stock split, reverse stock split, share consolidation or subdivision, spin-off, split-off or similar transaction or other change

in corporate structure affecting the Common Stock, the Board or Executive Compensation Committee shall make such adjustments and other

substitutions as the Board or Executive Compensation Committee deems equitable or appropriate, including, without limitation the following: (1) the

number and kind of shares available for future issuance under the 2025 ESAP shall be equitably adjusted by the Board or Executive Compensation

Committee to reflect the impact of the event; (2) for purposes of determining whether a Benchmark Date has occurred, the applicable price threshold

and the closing price shall be equitably adjusted to reflect the event; and (3) the incremental threshold that triggers a Benchmark Date and the

issuance of additional shares under the 2025 ESAP pursuant to the automatic awards shall remain $1.00. The Board or Executive Compensation

Committee may make such adjustments as it deems appropriate in the event of other changes affecting the Common Stock.

Any shares issued to the employee due to any dividend paid in the form of Common Stock or Common Stock issued in a stock split will be

issued to the employee and credited to the employee’s account at EQ, and the employee will be paid in cash for the amount of any fractional shares

issued to the employee.

How do employees vote shares of stock?

As a holder of Common Stock, employees will have the same voting rights as all other holders of Common Stock of ONEOK.

What is the source of the stock issued to employees under the 2025 ESAP?

Shares of Common Stock may be issued under the 2025 ESAP from: (1) authorized but unissued shares of ONEOK; (2) treasury shares of

ONEOK; (3) shares purchased by ONEOK on the open market; or (4) any combination of the above.

2025 ONEOK, Inc. Proxy Statement 143

Appendix B: ONEOK, Inc. 2025 Employee Stock Award Program

Are shares of Common Stock issued to employees under the 2025 ESAP subject to clawback, recoupment or forfeiture?

All shares of Common Stock issued under the 2025 ESAP are subject to the terms of any applicable clawback policies approved by the Board

or the Executive Compensation Committee, as in effect from time to time, whether approved before or after the date of issuance of shares of

Common Stock under the 2025 ESAP (as applicable, a “Clawback Policy”). In the event of a clawback, recoupment or forfeiture event under an

applicable Clawback Policy, the amount required to be clawed back, recouped or forfeited pursuant to such policy shall be deemed not to have been

earned under the terms of the 2025 ESAP, and the Company shall be entitled to recover the amount specified under the policy to be clawed back,

recouped or forfeited.

Can the 2025 ESAP be terminated, suspended or modified?

The 2025 ESAP will terminate on the day immediately before the tenth anniversary of the Effective Date, if not sooner terminated as described

below. ONEOK reserves the right to, at any earlier date, terminate, suspend, amend or modify the 2025 ESAP in whole or in part at any time, by

action of the Board. ONEOK will notify employees of any such termination, suspension or modification to the 2025 ESAP. No amendment or

modification to the 2025 ESAP which requires shareholder approval in order for the Plan to comply with Section 303A.08 of the New York Stock

Exchange Listed Company Manual, or any other applicable law, regulation or rule, shall be effective unless such amendment shall be approved by

the requisite vote of the shareholders.

How many shares of Common Stock are Authorized for Issuance under the 2025 ESAP?

The 2025 ESAP has been authorized a total of 700,000 shares of Common Stock for issuance, subject to adjustment as described above.

When the remaining shares available under the 2025 ESAP are not sufficient to ensure that all eligible employees will receive a share of Common

Stock on a particular Benchmark Date, no further shares will be issued under the 2025 ESAP.

What law governs the 2025 ESAP?

The 2025 ESAP and its operations are governed by the laws of the state of Oklahoma and federal securities laws, if and as applicable.
