Announces 2025 Second Quarter Earnings Release and Conference Call Schedule

Midland, Texas, July 30, 2025 -- Natural Gas Services Group, Inc. (NYSE: NGS), (“NGS” or the “Company”), a leading provider of natural gas compression equipment, technology, and services to the energy industry, today announced that its Board of Directors has declared the first-ever quarterly cash dividend of $0.10 per share of common stock, or $0.40 per share of common stock on an annualized basis. This cash dividend will be paid on August 22, 2025 to all stockholders of record as of the close of business on August 8, 2025.

Justin Jacobs, Chief Executive Officer of NGS stated, “This dividend marks a significant milestone in the history of NGS. It is a testament to our strong financial performance, confidence in the future of our business, and commitment to delivering long-term shareholder value. We believe now is an ideal time to initiate a modest dividend as our business continues to grow and take market share, and our balance sheet and low leverage ratio have us in perhaps the best financial position in the industry. The initial dividend represents the beginning of our shareholder return of capital plan—we expect this plan to grow as our business continues to expand faster than our competition.”

Future declarations of quarterly dividends and the establishment of future record and payment dates are subject to approval by the Board of Directors.

NGS also announced today that it will release its second quarter 2025 financial results on Monday, August 11, 2025, after the market closes via press release and made available on the Company’s website (http://www.ngsgi.com/).
