PART I

EXPLANATORY NOTE

On April 4, 2022, Kinetik Holdings Inc. (the “Company”) filed a Registration Statement on Form S-3 (Registration No. 333-264117) (the “Original Registration Statement”) with the Securities and Exchange Commission relating to 15,000,000 shares of the Company’s Class A common stock, par value $0.0001 per share (“Class A common stock”), reserved for issuance under the Company’s Dividend Reinvestment Plan (the “Plan”). The Original Registration Statement became effective upon filing.

On May 19, 2022, the Company announced a stock split with respect to its Class A common stock and Class C common stock, par value $0.0001 per share (“Class C common stock”) in the form of a stock dividend (the “Stock Split”). The Stock Split was accomplished by distributing one additional share of Class A common stock for each share of Class A common stock outstanding and one additional share of Class C common stock for each share of Class C common stock outstanding. The additional shares of common stock were issued on June 8, 2022 to holders of record at the close of business on May 31, 2022. Pursuant to Rule 416(a) under the Securities Act of 1933, the number of shares of Class A common stock covered by the Original Registration Statement was adjusted to 30,000,000 in connection with the Stock Split.

Effective July 12, 2024, the Company appointed a new administrator for the Plan. Information concerning the operation of the Plan is provided in the definitive prospectus filed as part of this Post-Effective Amendment No. 1 to the Original Registration Statement (this “Amendment”). The prospectus included in the Original Registration Statement is hereby amended to (i) provide updated information in respect of the manner in which the Plan operates and identify the new administrator of the Plan and (ii) include treasury shares as a source of shares that may be purchased under the Plan. No new shares are being registered pursuant to this Post-Effective Amendment No. 1 or have been added to the Plan. The registration fees with respect to the shares of Class A common stock registered under the Original Registration Statement were paid at the time of the original filing of the registration statement.

The text of the prospectus, as amended, is set forth below.

PROSPECTUS

KINETIK HOLDINGS INC.

DIVIDEND REINVESTMENT PLAN

30,000,000 shares of Class A Common Stock

This prospectus relates to 30,000,000 shares of Class A common stock, $0.0001 par value per share (“Class A common stock”), Kinetik Holdings Inc. (the “Company”) reserved for issuance under the Company’s Dividend Reinvestment Plan (the “Plan”). The Plan provides holders of shares of Class A common stock of the Company and the unitholders in Kinetik Holdings LP, a Delaware limited partnership and subsidiary of the Company (“Kinetik OpCo”), with a convenient method to reinvest dividends with respect to our Class A common stock and cash distributions with respect to common units in Kinetik OpCo (“Common Units”) in, within the limits of the Plan, shares of Class A common stock without payment of any brokerage commissions or service charges. If you are a beneficial owner of our Class A common stock and you are participating through your broker, you should consult your broker to confirm there are no service fees charged by your broker. The Class A common stock may be newly issued shares or treasury shares purchased directly from the Company.

Participants in the Plan may have at least 20% of the cash dividends on their shares or cash distributions on their common units, as applicable, automatically reinvested in shares of Class A common stock.

The price of Class A common stock if purchased directly from the Company will be a dollar amount per share for each dividend payment date equal to 97% of the volume-weighted average price per share of Class A common stock on the principal national securities exchange or automated or electronic quotation system on which shares of Class A common stock are then listed or admitted to trading, as reported by Bloomberg L.P., or its successor, for the five trading days immediately preceding, but excluding, the applicable dividend payment date.

Our Class A common stock is listed on the New York Stock Exchange and trades under the ticker symbol “KNTK”.

In reviewing this prospectus, you should carefully consider the matters described under the caption “Risk Factors” on page 8.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

The information in this prospectus and the documents incorporated by reference herein contain various statements, including those that express belief, expectation or intention, as well as those that are not statements of historic fact, that are forward-looking statements within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act.

All statements other than statements of historical facts included or incorporated by reference in this prospectus, including, without limitation, statements regarding our future financial position, business strategy, budgets, projected revenues, projected costs and plans, and objectives of management for future operations, are forward-looking statements. In addition, forward-looking statements generally can be identified by the use of forward-looking terminology such as “may,” “will,” “could,” “expect,” “intend,” “project,” “estimate,” “anticipate,” “plan,” “believe,” “continue,” “seek,” “guidance,” “might,” “outlook,” “possibly,” “potential,” “prospect,” “should,” “would,” or similar terminology. The absence of these words does not mean that a statement is not forward looking. Although we believe that the expectations reflected in such forward-looking statements are reasonable under the circumstances, we can give no assurance that such expectations will prove to have been correct. Key factors that could cause actual results to differ materially from our expectations include, but are not limited to, assumptions about::

We expressly qualify in their entirety all forward-looking statements attributable to us or any person acting on our behalf by the cautionary statements contained or referred to in this section.

These risks and uncertainties are not exhaustive. Other sections of this prospectus describe additional factors that could adversely affect our business and financial performance. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible to predict all risks and uncertainties, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

Although we believe the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, level of activity, performance or achievements. Moreover, neither we nor any other person assumes responsibility for the accuracy or completeness of any of these forward-looking statements. You should not rely upon forward-looking statements as predictions of future events. We are under no duty to update any of these forward-looking statements after the date of this prospectus to conform our prior statements to actual results or revised expectations, and we do not intend to do so.

RISK FACTORS

Investment in any securities offered pursuant to this prospectus involves risks. You should carefully consider the below risk factor and the risk factors incorporated by reference in our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K we file after the date of this prospectus, and all other information contained or incorporated by reference into this prospectus, as updated by our subsequent filings under the Exchange Act, before acquiring any of such securities. The occurrence of any of these risks might cause you to lose all or part of your investment in the offered securities.

Risks Related to the Plan

You will not know the price of the Class A common stock you are purchasing under the Plan at the time you elect to have your dividends reinvested, and you may not be able to direct the time or price at which the Class A common stock you hold is sold under the Plan.

The price of our Class A common stock may fluctuate between the time you decide to purchase Class A common stock under the Plan and the time of actual purchase. If an Enrollment Form is received by the Administrator on or before the record date for the payment of the next dividend, the dividend or distribution, as applicable, will be reinvested as of the dividend payment date. If an Enrollment Form is not received by the record date, reinvestment of dividends or distributions, as applicable, will not begin until the next following dividend payment date. In addition, during this time period, you may become aware of additional information that might affect your investment decision.

Broadridge serves as the Administrator of the Plan. If you instruct the Administrator to sell Class A common stock under the Plan, you will not be able to direct the time or price at which the Class A common stock is sold. The price of our Class A common stock may decline between the time you decide to sell Class A common stock and the time of actual sale.

8

USE OF PROCEEDS

The proceeds from the sale of the newly issued shares and treasury shares of Class A common stock offered by this prospectus will be used for general corporate purposes. Pending any such uses, we may invest the net proceeds from the sale of any securities in interest-bearing short-term investments, including money market accounts.

DESCRIPTION OF THE PLAN

The following is a question-and-answer statement of the provisions of the Plan. The Plan will continue until the earlier of the date that all shares of Class A common stock registered under the Plan have been sold or the date we terminate the Plan.

Purpose and Advantages

1. What is the purpose?

The purpose is to provide holders of record of the Company’s Class A common stock and the OpCo Partners with a simple and convenient method of reinvesting cash dividends on their shares or cash distributions on their Common Units, as applicable, in additional shares of the Company’s Class A common stock without payment of brokerage commissions or service charges.

2. What are the advantages of the Plan?

In addition to eliminating brokerage commissions, service charges, fees and other expenses in connection with purchases under the Plan, participants achieve full investment for funds because the Plan permits fractional shares of Class A common stock to be credited to participants’ accounts. In addition, dividends in respect of such fractional shares of Class A common stock, as well as full shares of Class A common stock, are so credited. Regular statements of account are issued to provide simplified record keeping.

Eligibility

3. Who is eligible to participate in the Plan?

All holders of record of the Company’s Class A common stock and the OpCo Partners are eligible to participate in the Plan and may do so with respect to all or a portion of their shares of Class A common stock held or to be held in the record holder’s name, or Common Units, as applicable. Beneficial owners of the Company’s Class A common stock registered in a name other than their own, such as that of a broker, bank nominee or trustee, must first become holders of record of such shares of Class A common stock in order to participate directly in their own name or make arrangements with such party authorizing them to participate in the Plan on their behalf.

As a participant in the Plan:

If you choose partial dividend reinvestment, you can have your cash dividends or cash distributions, as applicable, deposited directly into your bank account instead of receiving a check by mail. To have your cash dividends or cash distributions, as applicable, deposited electronically, you may enroll online or complete and submit an Enrollment Form, copies of which may be obtained from the Administrator. Please allow 30 days from the date of the Administrator’s receipt of a properly submitted form for the direct deposit to be established. You may also change your designated bank account for direct deposit or discontinue this feature by logging into your account online, calling the Administrator or submitting a written notice to the Administrator at the address noted in Question No. 4 below.

10

Administration

4. Who administers the Plan for the participants and what are the responsibilities of the Administrator?

Broadridge is the Administrator of the Plan. Should Broadridge resign or be discharged, another Administrator would be appointed by the Company. The Administrator primarily receives participants’ dividends or distributions, as applicable, invests such funds in shares of the Company’s Class A common stock, holds such shares of Class A common stock in its or its nominee’s name as agent for the participants under the Plan, maintains records of participants’ accounts and advises participants as to all transactions in and the status of their accounts. All notices from the Administrator to a participant will be addressed to the participant’s last known address. Participants should notify the Administrator promptly of any change of address.

In performing its duties under the Plan, the Administrator shall not be liable for any act done in good faith, or for any good faith omission to act, including, without limitation, any failure to terminate a participant’s account upon the participant’s death prior to receipt of notice in writing of such death.

For information regarding the Plan, you may contact the Administrator in one of the following manners:

Participation

5. How does a shareholder or OpCo Partner become a participant?

A holder of record of the Company’s Class A common stock or OpCo Partner may join the Plan by signing an Enrollment Form and returning it to the Administrator. Enrollment Forms will be furnished upon request made to the Administrator.

6. What does the Enrollment Form provide and how may a participant change participation alternatives?

The Enrollment Form provides for the purchase of additional shares of our Class A common stock through the following investment options:

Holders of our Class A common stock or OpCo Partners may select either one of the dividend reinvestment alternatives. The cash dividends on shares of Class A common stock held for your account under the Plan will be reinvested in accordance with the Plan, including dividends on shares of Class A common stock purchased through reinvested dividends, unless you specify otherwise.

If you submit an Enrollment Form properly executed but with no investment alternative designated, you will be enrolled in the “Full Dividend Reinvestment” option of the Plan.

As a participant, you may change your investment alternatives at any time via the Internet, by telephone or requesting a new Enrollment Form and returning it to the Administrator at the address set forth in Question No. 4. If a properly submitted Enrollment Form changing the reinvestment of cash dividends or cash distributions, as applicable, is received before the record date for payment of the related cash dividend or distribution, the change generally will be effective on the related dividend payment date. If the Enrollment Form is received on or later than the record date for payment of the related cash dividend or distribution, the change generally will be put into effect on the next following dividend payment date.

7. When will dividends and distributions be reinvested?

Dividends and distributions will be reinvested as of each dividend payment date. If an Enrollment Form is received by the Administrator on or before the record date for the payment of the next dividend, the dividend or distribution, as applicable, will be reinvested as of the dividend payment date. If an Enrollment Form is not received by the record date, reinvestment of dividends or distributions, as applicable, will not begin until the next following dividend payment date.

12

Purchases

8. What is the source of the shares of Class A common stock purchased under the Plan?

The Administrator will purchase the Class A common stock under the Plan directly from the Company out of authorized but unissued shares or treasury shares.

9. How many shares of Class A common stock will be purchased for participants?

The number of shares of Class A common stock that will be purchased for each participant will depend on the amount of dividends or distributions, as applicable, to be reinvested in a participant’s account and the applicable purchase price of the Class A common stock (see Question No. 10). Each participant’s account will be credited with that number of shares of Class A common stock, including any fractional interest computed to three decimal places, equal to the total amount to be invested divided by the applicable purchase price as described in Question No. 10 below.

10. At what price will shares of Class A common stock be purchased under the Plan?

The price of shares of Class A common stock purchased from the Company with reinvested cash dividends or cash distributions, as applicable, will be a dollar amount per share for each dividend payment date, as the case may be, equal to 97% of the volume-weighted average price per share of Class A common stock on the principal national securities exchange or automated or electronic quotation system on which shares of Class A common stock are then listed or admitted to trading, as reported by Bloomberg L.P., or its successor, for the five trading days immediately preceding, but excluding, the applicable dividend payment date.

It should be recognized that since investment prices are determined as of particular dates, a participant loses any advantage otherwise available from being able to select the timing of investments.

Costs

11. What costs do participants pay?

Participants will incur no brokerage commissions or other charges for purchases made under the Plan. However, there are fees for certain other services such as when a participant withdraws from the Plan and directs the Administrator to sell the shares of Class A common stock held in the participant’s account (see Question No. 16). With these exceptions, all costs in connection with the Plan are paid by the Company.

Reports to Participants

12. What reports are sent to participants in the Plan?

Each participant in the Plan receives a statement of such participant’s account quarterly that provides a record of all current transactions and should be retained for income tax purposes. In addition, each participant in the Plan (including OpCo Partners) will be sent the same communications sent to every holder of Company Class A common stock, including the Company’s Annual Reports, the Notice of Annual Meeting and Proxy Statement and income tax information for reporting dividends paid.

Certificates for Shares of Class A Common Stock

13. Are certificates issued to participants for shares of Class A common stock purchased under the Plan?

Shares of Class A common stock purchased under the Plan are registered in the name of the Administrator, or its nominee, as agent for the participants in the Plan, and certificates for such shares are not delivered to participants. The number of shares of Class A common stock credited to an account under the Plan is shown on the participant’s statement. Participants are thus protected against loss, theft or destruction of stock certificates.

13

Withdrawal of Shares of Class A Common Stock in Plan Accounts

14. How may a participant withdraw shares of Class A common stock purchased under the Plan?

A participant may withdraw all or a portion of the shares of Class A common stock credited to the participant’s account by notifying the Administrator to that effect and specifying in the notice the number of shares of Class A common stock to be withdrawn, or by completing and returning the form contained within the participant’s statement of account. This notice or form should be mailed to the Administrator at the address shown in Question No. 4 above. Any notice of withdrawal received after a dividend record date will result in the dividends paid for such record date to be paid in cash, which amounts will be included in the check issued in connection with the withdrawal. Such dividends will not be reinvested. Any fractional interest withdrawn will be liquidated by the Administrator on the basis of the then current market value of the Class A common stock and a check will be issued for the proceeds thereof. Alternatively, you may choose to sell your shares of Class A common stock through a broker of your choice, in which case you would request that the Administrator electronically transfer your shares of Class A common stock to your broker through the Direct Registration System.

15. What is the effect on a participant’s Plan account if the participant withdraws all of the whole shares held in the account but does not terminate the account?

Dividends on shares of Class A common stock participating in the Plan held of record by the participant and on the fractional share remaining in the account would continue to be invested under the Plan in additional shares of Class A common stock. However, the Company has the right at its discretion to terminate any account which has less than five shares of Class A common stock remaining in the participant’s Plan account.

Sale of Shares of Class A Common Stock

16. What procedures should be followed if a participant wishes to sell shares of Class A common stock?

If you are a registered holder of our Class A common stock and you are directly participating in the Plan, you can sell your Class A common stock at any time by contacting the Administrator. As further described below, sales may be executed as market orders, day limit orders or batch orders. Your sale request will be processed, and your Class A common stock will, subject to market conditions and other facts, generally be sold within five business days of receipt and processing of your request. Please note that the Administrator cannot and does not guarantee the actual sale date or price, nor can it stop or cancel any outstanding sale or issuance requests. All requests are final. The Administrator will mail a check to you (less applicable sales fees) on the settlement date, which is one business day after your Class A common stock have been sold. Please allow an additional five to seven business days from the settlement date to receive your check.

Market Order: A market order is a request to sell shares promptly at the current market price. Market order sales can be initiated through our website by logging into your shareholder account or by contacting the Administrator by telephone. Market order sale requests will be submitted to a registered broker-dealer utilized by the Plan promptly upon receipt during market hours (normally 9:30AM to 4:00PM Eastern Time). Any orders received during the hours that the market is not open, will be submitted to a registered broker-dealer utilized by the Plan promptly the next business day when the market is open. All market orders are considered irrevocable upon final submission of the order and cannot be cancelled. Depending on the current trading activity of that security, there may not be a market for your request and the order could be cancelled at the end of the trading day resulting in no sale of such shares. To determine if shares were sold, a participating shareholder should access their account online at our website or by contacting the Administrator. If the market order sale was not filled and a participating shareholder still wants the shares sold, a sale request will need to be resubmitted. The price will be the market price of the sale obtained by the broker-dealer utilized by the Plan. Market order requests submitted to the Administrator outside of market hours (market hours are normally 9:30AM to 4:00PM Eastern Time), will be forwarded to the registered broker-dealer utilized by the Administrator on the next business day once the market

14

has opened. The Administrator, does not have control over, nor guarantee, the date, time, or pricing associated with any shares that are sold through the Plan. All sale orders are submitted as All-or-None (AON) orders and, depending on market conditions, the order may not be included in market open trades and/or not executed at all. Each market order sale will incur a flat administrative fee to the Administrator per transaction request. In addition, there is a brokerage commission fee per share sold (no portion of which will be retained by or forwarded to the Administrator).

Day Limit Order: A day limit order is an order to sell securities when and if the stock reaches a specific trading price on a specific day. The order is automatically cancelled if the price is not met by the end of the trading day (or, for orders placed after-market hours, the next business day the market is open). All limit orders are considered irrevocable upon final submission of the order and cannot be cancelled within market trading hours. Depending on the current trading activity of that security, there may not be a market for your request and the order could be cancelled at the end of the trading day resulting in no sale of such shares. Should you submit a limit order that falls under the current trading price at the time of receipt by the broker-dealer utilized by the Plan, there is a chance the order will be cancelled upon receipt if it exceeds certain pricing thresholds meant to protect you from erroneous entries. Please check your account transaction upon the submission of any limit orders submitted to ensure it was received and accepted. The order may be cancelled by the applicable stock exchange or by the broker engaged by the Administrator due to certain restrictions. Each day limit order sale will incur a flat administrative fee to the Administrator per transaction request. In addition, there is a brokerage commission fee per share sold (no portion of which will be retained by or forwarded to the Administrator). All sale orders are submitted as All-or-None (AON) orders.

Batch Order: The Administrator will automatically treat all sale requests received in writing as batch order sales requests. Individuals participating in the Plan should be aware that the share price may fluctuate between the time your transaction request is received and the time the transaction is affected on the open market. This price risk will be borne solely by you. The Administrator may, but is not obligated to, accept written requests to revoke transaction requests. Please be aware that all sales options may always not be available, and options are pending availability at the Administrator.

Alternatively, you may choose to withdraw your Class A common stock from your Plan account and sell them through a broker of your choice, in which case you would have to request that the Administrator electronically transfer your Class A common stock to the broker through the Direct Registration System.

If you are a beneficial owner of our Class A common stock and you are participating in the Plan through your broker, you should contact your broker to sell your Class A common stock.

Following each sale of shares of Class A common stock through the Plan, a participant will receive a check with an information stub from the Administrator showing the date of sale, number of shares sold and sale price. As with other Plan statements received, participants should retain these sale information stubs for their tax records. All 1099-B forms will be issued and mailed by the end of the tax year. Proceeds from each sale of shares of Class A common stock through the Plan will be remitted to the participant less brokerage commissions and applicable handling fees.

Discontinuation of Dividend Reinvestment

17. How does a participant discontinue participation under the Plan?

A participant may discontinue participation under the Plan by notifying the Administrator in writing to that effect, or by completing and returning the form contained within the participant’s statement of account. Any notice of discontinuation received after a dividend record date will not be effective until dividends paid for such record date have been reinvested and the shares of Class A common stock purchased have been credited to the participant’s account. In addition, the participant may request the Administrator to sell all shares of Class A

15

common stock held in the participant’s account. Upon such request, the Administrator will sell the shares of Class A common stock in the open market as soon as practicable and pay the participant the proceeds of the sale less any applicable brokerage commissions, transfer taxes and other costs (see Question No. 16). Alternatively, you may choose to sell your shares of Class A common stock through a broker of your choice, in which case you would request that the Administrator electronically transfer your shares of Class A common stock to your broker through the Direct Registration System.

18. What happens if the Company issues a stock dividend, declares a stock split or has a rights offering with respect to Class A common stock?

Any shares resulting from a stock dividend or stock split with respect to Class A common stock (whole shares and any fractional interest) in a participant’s account will be credited to such account. The basis for any rights offering will include the shares of Class A common stock and any fractional interest credited to a participant’s account. The number of shares of Class A common stock subject to the Plan will be adjusted to reflect such events as stock dividends, stock splits, recapitalizations and like changes.

19. How will the shares of Class A common stock credited to a participant’s account be voted at a meeting of the Company’s shareholders?

If on a record date for a meeting of the Company’s shareholders there are shares credited to a participant’s account under the Plan, the participant will be sent proxy material for such meeting. A participant will be entitled to vote all shares of Class A common stock registered in the participant’s name, if any, as well as shares held by the Administrator for the account of the participant. The participant may vote by proxy or in person at any such meeting.

20. May the Plan be modified or discontinued?

The Company reserves the right to suspend or terminate the Plan at any time. It also reserves the right to make modifications to the Plan. The Company will endeavor to notify participants of any such suspension, termination or modification, but the absence of notification will not affect the effectiveness of the suspension, modification or termination. In addition, the Company may adopt rules and procedures for the administration of the Plan, interpret the provisions of the Plan and make any necessary determinations relating thereto. Any such rules, procedures, interpretations and determinations shall be final and binding.

21. What are the generally applicable U.S. federal income tax considerations of participating in the Plan?

The following summary describes certain U.S. federal income tax considerations generally applicable to a U.S. person (a “U.S. participant”) participating in the Plan with respect to distributions made in respect of shares of Class A common stock as of the date hereof. However, this summary does not reflect every situation that could result from participation in the Plan, nor does it address the tax implications of your ownership of shares of Class A common stock unrelated to the Plan. In addition, this summary applies only to U.S. participants (except where explicitly noted) and does not address all of the U.S. federal income tax consequences that may be relevant to a U.S. participant subject to special treatment under the U.S. federal income tax laws, including if you are a dealer in securities or currencies, a financial institution, a regulated investment company, a tax-exempt entity, an insurance company, a person holding shares of the Class A common stock as a part of a hedging, integrated, conversion or constructive sale transaction or a straddle, a trader in securities that elects to use a mark-to-market method of accounting for your securities holdings, a person liable for alternative minimum tax, a person required to accelerate the recognition of any item of gross income with respect to shares of Class A common stock as a result of such income being recognized on an applicable financial statement, a person who is a “foreign government” within the meaning of Section 892 of the Internal Revenue Code of 1986, as amended (the “Code”),

16

an investor in a pass-through entity or a person whose “functional currency” is not the U.S. dollar. The summary below also does not address the effects of the 3.8% tax on net investment income, alternative minimum tax, gift tax or state, local, or non-U.S. tax laws. Furthermore, the discussion below is based upon the provisions of the Code, and regulations, rulings and judicial decisions thereunder as of the date hereof, and such authorities may be repealed, revoked or modified, possibly with retroactive effect, so as to result in U.S. federal income tax consequences different from those discussed below. We have not and will not seek any rulings from the Internal Revenue Service (the “IRS”) regarding the matters discussed below. There can be no assurance that the IRS will not take positions concerning the tax consequences of participating in the Plan that are different from those discussed below. The summary below is not intended to be, and should not be construed to be, legal or tax advice to any particular participant in the Plan. You should consult your tax advisors concerning the U.S. federal income tax consequences in light of your particular situation as well as consequences arising under the laws of any other taxing jurisdiction.

Dividend Income

Under IRS rulings in connection with similar plans, dividends reinvested pursuant to the Plan will be treated for U.S. federal income tax purposes as taxable to you notwithstanding that the dividends are reinvested in Class A common stock. Under these rulings, a U.S. participant in the Plan generally is treated for U.S. federal income tax purposes as having received, on the dividend payment date, a distribution in an amount equal to the sum of (a) the fair market value of the shares of Class A common stock received pursuant to the Plan, (b) a pro rata share of any brokerage commissions paid by us in connection with the purchase of our Class A common stock by our Administrator, and (c) any cash distributions actually received with respect to your shares of Class A common stock, if any. Such distributions will generally be treated as dividends to the extent paid out of our “earnings and profits” (determined under U.S. federal income tax principles). To the extent that a distribution exceeds our “earnings and profits,” it is deemed to be a return of capital and will reduce your basis in shares of our Class A common stock, but not below zero. To the extent a distribution exceeds your basis, it is treated as a capital gain.

Tax Basis of Shares

The tax basis of shares of Class A common stock purchased with reinvested dividends pursuant to the Plan generally will be equal to the sum of (a) the fair market value of the shares of Class A common stock on the dividend payment date and (b) a pro rata share of any brokerage fees paid by us.

The Plan assumes that each participant will use the first-in, first-out (“FIFO”) method when determining the tax basis of any shares of Class A common stock sold. However, participants may designate their preference for a different method of determining the tax basis of shares by identifying this preference to the Administrator. In general, participants may designate their preference for “specific identification” cost basis or their preference for the “average basis method” at any time.

Holding Period of Shares

The holding period of any shares of Class A common stock purchased with reinvested dividends pursuant to the Plan, for purposes of determining whether any gain or loss on sale will be a long-term capital gain or loss, begins on the day after the relevant dividend payment date.

Gains and Losses from the Sale of Shares

A U.S. participant in the Plan will not realize a gain or loss for U.S. federal income tax purposes upon a transfer of shares to the Plan or the withdrawal of whole shares from the Plan. A U.S. participant will, however, generally realize a gain or loss at the time your shares of Class A common stock are sold by the Administrator or by you after withdrawal of the shares from the Plan. The amount of such gain or loss will be based on the

17

difference between the amount you receive for the shares of Class A common stock, reduced by the expenses of sale, including brokerage commissions and service fees charged for the sale of shares, and your tax basis in the shares. You also will recognize a gain or loss when you receive cash payments for fractional shares credited to your account upon your withdrawal from the Plan or the Plan’s termination. The amount of such a gain or loss will be the difference between the amount which you receive for your fractional shares and your tax basis in such shares. All participants in the Plan should consult their tax advisor as to the consequences of a sale of shares in view of their particular circumstances.

IRS Reports

The Administrator reports dividend income to participants and the IRS on Form 1099-DIV and may report income in the amount of any brokerage commissions or other fees paid by us on your behalf on Form 1099-MISC. The Administrator reports the proceeds from the sale of Plan shares to the selling participants and the IRS on Form 1099-B. For non-resident aliens or foreign corporations, partnerships or other entities, the Administrator will report dividend income to the selling participants and the IRS on Form 1042-S.

Dividends Subject to Withholding

Reinvested dividends may be subject to U.S. federal backup withholding tax. In addition, if you are a non-resident alien or a foreign corporation, partnership or other entity, your dividends may be subject to U.S. federal withholding tax. In any case in which U.S. federal taxes are required to be withheld, the amount reinvested on your behalf by the Administrator will be reduced by the amount of such tax withheld. For IRS reporting purposes, the amount of the tax withheld is included in the holder’s dividend income.

The foregoing is only a summary of the U.S. federal income tax consequences of participation in the Plan and does not constitute tax advice. This summary does not reflect every possible outcome that could result from participation in the Plan and, therefore, participants are advised to consult their tax advisors concerning the tax consequences applicable to their particular situation.

DESCRIPTION OF CAPITAL STOCK

The following summary of the material terms of the Class A common stock is not intended to be a complete summary of the rights and preferences of such securities and is subject to and qualified by reference to our Charter and our bylaws, and applicable Delaware law, including Delaware General Corporation Law (the “DGCL”). We urge you to read our Charter and our bylaws in their entirety for a complete description of the rights and preferences of the Class A common stock.

Authorized Capital Stock

Our authorized capital stock consists of: (i) 1,500,000,000 shares of Class A common stock; (ii) 1,500,000,000 shares of Class C common stock; and (iii) 50,000,000 shares of preferred stock, par value $0.0001 per share (“Preferred Stock”).

Common Stock

Common stockholders of record are entitled to one vote for each share held on all matters to be voted on by stockholders. Holders of Class A common stock and Class C common stock vote together as a single class on all matters submitted to a vote of the Company’s stockholders, except as required by law. Unless specified in our Charter or bylaws, or as required by applicable provisions of the DGCL or applicable stock exchange rules, the affirmative vote of a majority of shares of Common Stock that are voted is required to approve any such matter voted on by our stockholders. There is no cumulative voting with respect to the election of directors, with the result that the holders of more than 50% of the shares voted for the election of directors can elect all the directors. Our stockholders are entitled to receive ratable dividends when, as and if declared by our board of directors out of funds legally available therefor.

In the event of a liquidation, dissolution, or winding up of the Company, our Class A stockholders are entitled to share ratably in all assets remaining available for distribution to them after payment of liabilities and after provision is made for each class of stock, if any, having preference over the Common Stock. Our stockholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the Common Stock.

A holder of Class C common stock may transfer shares of Class C common stock to any transferee (other than us) only if, and only to the extent permitted by Kinetik OpCo LPA, such holder also simultaneously transfers an equal number of such holder’s common units representing limited partner interests in Kinetik OpCo to such transferee in compliance with the Kinetik OpCo LPA. In addition, the holders of Class C common stock, voting as a separate class, will be entitled to approve any amendment, alteration, or repeal of any provision of our Charter that would alter or change the powers, preferences or relative, participating, optional or other special rights of the Class C common stock. Holders of Class C common stock are not entitled to any dividends and are not entitled to receive any of our assets in the event of any voluntary or involuntary liquidation, dissolution, or winding up of our affairs.

Preferred Stock

Our Charter provides that up to 50,000,000 shares of Preferred Stock may be issued from time to time in one or more series. Our board of directors is authorized to fix the voting rights, if any, designations, powers, preferences, or relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. Our board of directors can, without stockholder approval, issue Preferred Stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the Common Stock and could have anti-takeover effects. The ability of our board of directors to issue Preferred Stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of us or the removal of existing management. We have no Preferred Stock outstanding at the date hereof. Although we do not currently intend to issue any shares of Preferred Stock, we cannot assure you that we will not do so in the future.

19

Dividends

Holders of Class A common stock are entitled to receive ratable dividends when, as, and if declared by our board of directors out of funds legally available therefor. Holders of Class C common stock are not entitled to any dividends from the Company.

Our Transfer Agent

The transfer agent for our Common Stock is Broadridge Corporate Issuer Solutions, LLC. We have agreed to indemnify Broadridge Corporate Issuer Solutions, LLC in its roles as transfer agent, its agents and each of its affiliates, consultants, directors, officers, and employees against all claims and losses that may arise out of acts performed or omitted for its activities in that capacity, except for any liability due to any gross negligence, willful misconduct, or bad faith of the indemnified person or entity.

Certain Anti-Takeover Provisions of Delaware Law and our Charter and Bylaws

We are subject to the provisions of Section 203 of the DGCL regulating corporate takeovers. This statute prevents certain Delaware corporations, under certain circumstances, from engaging in a “business combination” with:

A “business combination” includes a merger or sale of more than 10% of our assets. However, the above provisions of Section 203 do not apply if:

Our authorized but unissued Common Stock and Preferred Stock are available for future issuances without stockholder approval (including a specified future issuance) and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved Common Stock and Preferred Stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Exclusive forum for certain lawsuits

Our Charter requires, to the fullest extent permitted by law, that derivative actions brought in our name, actions against directors, officers, and employees for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the State of Delaware and, if brought outside of Delaware, the stockholder bringing the suit will be deemed to have consented to service of process on such stockholder’s

20

counsel. Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers.

Special meeting of stockholders

Our Charter provides that at any time when any stockholder beneficially owns, in the aggregate, at least 10% in voting power of our Common Stock entitled to vote generally in the election of directors, special meetings of the stockholders for any purpose or purposes shall also be called by or at the direction of our board of directors or the Chairman of our board of directors at the request of such stockholder.

Action by written consent

Unless otherwise provided in the Charter and subject to the terms of any preferred stock, any action required or permitted to be taken at any annual or special meeting of stockholders may be taken without a meeting, without prior notice and without a vote, if a consent or consents, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to us in accordance with the DGCL.

Listing of Securities

Our shares of Class A common stock are listed on the New York Stock Exchange under the symbol “KNTK.”

21

PLAN OF DISTRIBUTION

The shares of Class A common stock that participants acquire under the Plan will be newly issued shares or treasury shares sold directly by the Company through the Plan. As stated elsewhere in this prospectus, the Company will pay any brokerage fees or commissions for shares purchased under the Plan.

Persons who acquire shares of the Company’s Class A common stock through the Plan and resell them shortly after acquiring them, including coverage of short positions, under certain circumstances may be participating in a distribution of securities that would require compliance with Regulation M under the Exchange Act and may be considered to be underwriters within the meaning of the Securities Act. The Company will not extend to any such person any rights or privileges other than those to which he, she or it would be entitled as a participant in the Plan, nor will the Company enter into any agreement with any such person regarding the resale or distribution by any such person of the shares of the Company’s Class A common stock so purchased.

This prospectus does not constitute an offer to sell, or a solicitation of an offer to buy, any of the Company’s Class A common stock or other securities in any jurisdiction to any person to whom it is unlawful to make such offer in such jurisdiction.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

The following table sets forth the costs and expenses payable by the registrant in connection with the issuance of the securities. All amounts are estimates except the SEC registration fee.

Section 145 of the DGCL, as amended, authorizes us to indemnify any director or officer under certain prescribed circumstances and subject to certain limitations against certain costs and expenses, including attorney’s fees actually and reasonably incurred in connection with any action, suit, or proceeding, whether civil, criminal, administrative, or investigative, to which a person is a party by reason of being one of our directors or officers if it is determined that such person acted in accordance with the applicable standard of conduct set forth in such statutory provisions.

Our Charter provides that our officers and directors are indemnified by us to the fullest extent authorized by Delaware law, as it now exists or may in the future be amended. In addition, our Charter provides that our officers and directors will not be personally liable for monetary damages to us or our stockholders for breaches of their fiduciary duty as officers or directors, unless they: violated their duty of loyalty to us or our stockholders; acted in bad faith; knowingly or intentionally violated the law; with respect to any director, authorized unlawful payments of dividends, unlawful stock purchases or unlawful redemptions; derived an improper personal benefit from their actions as officers or directors; or, with respect to any officer, in any action by or in the right of us.

Our bylaws permit us to secure insurance on behalf of any officer, director, or employee for any liability arising out of his or her actions, regardless of whether Delaware law would permit such indemnification. We have purchased a policy of directors’ and officers’ liability insurance that insures our officers and directors against the cost of defense, settlement or payment of a judgment in some circumstances and insures us against our obligations to indemnify our officers and directors. In addition, we have entered into indemnification agreements with certain of our directors and executive officers. These agreements require us to indemnify these individuals to the fullest extent permitted under Delaware law against liabilities that may arise by reason of their service to us, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, or persons controlling us pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC, such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.

II-1

II-2

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii), and (a)(1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is a part of the registration statement.

II-3

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(h) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

Ladies and Gentlemen:

We have acted as counsel for Kinetik Holdings Inc., a Delaware corporation (the “Company”) in connection with the registration of the sale of up to 30,000,000 shares of Class A common stock, par value $0.0001 per share (the “Shares”), which may be issued pursuant to the Company’s Dividend and Distribution Reinvestment Plan (the “Plan”), pursuant to the Company’s Post-Effective Amendment No. 1 to the registration statement on Form S-3 filed on the date hereof by the Company (the “Registration Statement”) with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”).

In connection with the rendering of the opinions hereinafter set forth, we have examined (i) executed copies of the organizational documents of the Company; (ii) the Registration Statement; (iii) the prospectus included in the Registration Statement dated the date of the Registration Statement (the “Prospectus”); (iv) the Plan, (v) resolutions of the Board of Directors of the Company; and (vi) such other certificates, statutes and other instruments and documents as we considered appropriate for purposes of the opinions hereafter expressed. In addition, we reviewed such questions of law as we considered appropriate.

Based on the foregoing, and subject to the assumptions, qualifications, limitations and exceptions set forth herein, we are of the opinion that the Shares, when issued and delivered against payment therefor as provided in the Plan, will be validly issued, fully paid and non-assessable.
