MESSAGE TO OUR STOCKHOLDERS

March 12, 2024

Dear Fellow Stockholder:

On behalf of the Board of Directors and our management team, we cordially invite you to attend Archrock, Inc.’s Annual Meeting of Stockholders, which will be held at 11:00 a.m. Eastern Time on Thursday, April 25, 2024 at The Wall Street Hotel – Exchange Room, New York, New York 10005.

At this meeting, you will have a chance to vote on the matters set forth in the accompanying Notice of Annual Meeting and Proxy Statement.

During 2023, market demand for natural gas remained robust and we saw record natural gas production in the U.S. driven in large part by strong activity in oil producing basins with associated gas like the Permian. The powerful combination of expected continued growth in natural gas production and the commendable capital discipline we are seeing across the energy industry began to materialize into what we believe will be a steady and durable upcycle for our business.

For Archrock, 2023 was a year for the history books. We achieved an extensive list of impressive and in many cases record-breaking accomplishments. We are proud of our strategic, operational and financial execution in 2023, from achieving all-time high equipment utilization and pricing to increasing our dividend per share (twice) and implementing a stock-buyback program. Additionally, we exceeded our safety performance goals and continued to harness innovative technologies and processes both internally and through investments in methane mitigation as well as in a cutting-edge carbon capture technology company.

These results, highlighted in our financial statements and throughout this Proxy Statement, reflect years of effort to transform our platform and our commitment to a sustainable future. We believe the actions we’ve taken to high-grade our asset base, utilize innovative technology, refine our capital allocation and prioritize opportunities to help our customers decarbonize will benefit us for years to come and in a variety of markets.

We celebrate 70 years of operations in 2024, a testament to the resilient business we’ve built through a mindset of continuous improvement. There is always more work to be done and the opportunity to deliver the next level of value for all of our stakeholders. We continue to be focused on:

The future for natural gas and Archrock is bright. We will remain true to our core as an energy infrastructure company, supplying the compression required to keep U.S. natural gas moving while embodying our purpose:WE POWER A CLEANER AMERICA™.

Your vote is important, regardless of how many shares your own. Whether or not you plan to attend the Annual Meeting, please vote by internet, telephone or mail as soon as possible to ensure your vote is recorded promptly. The instructions set forth in the Proxy Statement and on the proxy card explain how to vote your shares.
