Notice of Annual Meeting of Stockholders

and Proxy Statement

May 19, 2026

Dear Stockholder,

2025 was a year of meaningful strategic progress amid a challenging operating environment for Kinetik. Persistent commodity price volatility, inflationary pressures, and moderated producer activity created a difficult operating backdrop. Despite these headwinds, we executed several key initiatives that strengthened our commercial foundation and reinforced the long‑term competitiveness of our system.

“As we look ahead, our priorities remain centered on consistent execution, operational excellence, and continued advancement of projects that strengthen the durability and scale of our integrated system.”

During the year, we achieved commercial in‑service at the Kings Landing Processing Complex (the “Kings Landing Plant”), the culmination of a multi-year development that doubled gas processing capacity in Delaware North and has demonstrated exceptional operational reliability since start-up. We reached a final investment decision to convert the Kings Landing Plant for sour gas service, which we expect to expand our acid gas injection capacity and position the system to support producers as development increasingly targets gassier benches. In addition, we further strengthened our integrated footprint with the completion of the Barilla Draw acquisition and continued progress on the ECCC Pipeline, which will connect the Delaware North system to additional gas processing capacity in Delaware South.

We also took meaningful steps to reinforce our financial resilience during the year. Through the divestiture of our equity interest in EPIC Crude Holdings, LP (“EPIC ”), opportunistic access to the debt capital markets, and the refinancing and extension of our bank credit facilities, we enhanced our liquidity and financial flexibility. Proceeds from the EPIC transaction were used to reduce borrowings under our revolving credit facility, further strengthening our balance sheet and supporting our disciplined capital allocation priorities.

Collectively, these actions drove year-over-year growth in Adjusted EBITDA and processed gas volumes and have left us with a stronger midstream infrastructure system, a better-aligned commercial portfolio, and a platform well-positioned for long‑term value creation.

Most recently, we updated our capital allocation framework to better align with the multi-year growth opportunities supported by our expanding system and long‑term commercial commitments. The refreshed framework reflects a growth‑first mentality, prioritizing high‑return organic investment that enhances strategic value while maintaining ample liquidity and balance sheet discipline. It also outlines a clear approach to shareholder distributions, including annual dividend increases and the use of share repurchases as a meaningful contributor to longer‑term incremental returns. Together, these priorities support our goal of maximizing share price outcomes and delivering sustainable, long‑term value for shareholders.

As we look towards the upcoming year, we anticipate our priorities will remain centered on consistent execution, operational excellence, and continued advancement of projects that strengthen the durability and scale of our integrated system. Strategically positioned at the intersection of abundant, low‑cost natural gas supply and growing Gulf Coast demand, we believe Kinetik is well situated to enable multi-year producer development plans and capitalize on long‑term structural opportunities across the Delaware Basin. We enter 2026 and beyond with a clear mandate to deliver durable, compounding value for our shareholders.

Thank you for your continued support and confidence in Kinetik.

Jamie Welch, Chief Executive Officer and President
