Exhibit 99.1

Natural Gas Services Group Announces Upcoming Redomestication to Texas

Move Aligns the Company’s Legal Home with Its Corporate Headquarters

and the Heart of Its Operations in Texas

SOUTHLAKE, Texas, July 8, 2026 -- Natural Gas Services Group, Inc. ("NGS" or the "Company") (NYSE:NGS), a leading provider of natural gas compression equipment, technology, and services to the energy industry, today announced that it expects to complete the redomestication of the Company’s state of incorporation from Colorado to Texas, effective on or about July 20, 2026. The Company’s shareholders approved the redomestication at the 2026 Annual Meeting of Shareholders held on June 10, 2026, with the proposal receiving the support of approximately 99% of the shares voted on the matter.

Texas is the center of NGS’s business. The Company is headquartered in Southlake, Texas, maintains administrative offices in Midland, Texas, and provides natural gas and electric compression services across the Permian Basin, Eagle Ford and other major oil and natural gas producing regions in the state. The redomestication aligns the Company’s state of incorporation with the location of its corporate headquarters, its people, and many of the customers and basins it serves.

“Redomesticating to Texas was a straightforward decision for NGS. Texas is where our headquarters are located, where our leadership team is based, and where much of our business is conducted. Aligning our state of incorporation with our operational home is the right long-term decision for the Company. Texas also offers a strong business climate and corporate legal framework that we believe benefits NGS and our shareholders. We appreciate the overwhelming support of our shareholders in approving this redomestication, and we are proud to call Texas home,” said Justin Jacobs, Chief Executive Officer of NGS.

The redomestication will be effected through a conversion under which NGS will change its state of incorporation from Colorado to Texas. The Company will continue in existence as a Texas corporation under the name “Natural Gas Services Group, Inc.” The redomestication will not result in any change to the Company’s business, operations, management, strategy, assets, or the location of its offices or facilities. NGS’s common stock is expected to continue its listing on the New York Stock Exchange under the symbol “NGS,” and shareholders will not be required to take any action.

In connection with the redomestication, the Company’s previously staggered board structure will be replaced with the annual election of directors, with all directors standing for election each year. The redomestication is expected to become effective upon the filing of the required conversion documents with the Secretaries of State of Texas and Colorado.
