Deborah L. Byers - 19 May 2026 Form 4 Insider Report for Kinetik Holdings Inc. (KNTK)

Footnote F1

Includes a fully vested award of restricted stock units ("RSUs") that may be settled only for shares of common stock on a one-for-one basis. Pursuant to the Reporting Person's election under the Kinetik Holdings Inc. (the "Company") Amended and Restated 2019 Omnibus Compensation Plan, as amended from time to time (the "Plan"), settlement of such vested RSUs has been deferred until the earlier to occur of the following: (a) the termination of the Reporting Person's service relationship with the Company or (b) change in control (as defined in the Plan).

Footnote F2

While the RSUs remain outstanding, an amount equal to the dividends that would have been paid on the RSUs had they been in the form of common stock will be reinvested into additional RSUs based on the same amount at which dividends are reinvested pursuant to the Company's Dividend Reinvestment Plan, as amended from time to time (the "DRIP"). The additional RSUs will be immediately vested in full and pursuant to the Reporting Person's election under the Plan, will be settled at the same time as the initial RSUs subject to the award, as described in Note 1 above.

Footnote F3

Amount reported includes approximately 610 additional RSUs acquired by the Reporting Person since the date of the Reporting Person's last Form 4 in connection with the reinvestment of dividends described herein.

Footnote F4

Includes an award of RSUs granted to the Reporting Person under the Company's Plan that will generally vest on January 1, 2027, subject to the Reporting Person's continued service relationship with the Company through such date and may be settled only for shares of common stock on a one-for-one basis.

Footnote F5

The Reporting Person received a grant of deferred stock units ("DSUs") in lieu of director cash compensation. Once vested, each DSU represents a contingent right to receive an amount in cash equal to the value of one share of the Company's Class A Common Stock. 1,091 DSUs vested on April 1, 2023, 1,091 DSUs vested on July 1, 2023, 1,090 vested on October 1, 2023 and 1,091 DSUs vested on January 1, 2024. Pursuant to the Reporting Person's election under the Plan, settlement of vested DSUs has been deferred until the earlier to occur of the following: (a) the termination of the Reporting Person's service relationship with the Company or (b) change in control.

Footnote F6

While the DSUs remain outstanding, an amount equal to the dividends that would have been paid on the DSUs had they been in the form of common stock will be reinvested into additional DSUs based on the same amount at which dividends are reinvested pursuant to the DRIP. The additional DSUs are subject to the same vesting schedule described above for the initial DSUs meaning that such additional DSUs are immediately vested as the initial DSUs have already fully vested and pursuant to the Reporting Person's election under the Plan, such vested additional DSUs will be settled at the same time as the initial DSUs subject to the award. Amount reported includes approximately 288 additional DSUs acquired by the Reporting Person since the date of the Reporting Person's last Form 4 in connection with the reinvestment of dividends described herein.
