Release Details

MIDLAND, Texas, Oct 23, 2003 /PRNewswire-FirstCall via COMTEX/ -- Natural Gas Services Group, Inc. (Amex: NGS), a leading provider of equipment and services to the natural gas and oil industry, announces it has been one year since their IPO and the Company has grown significantly. In the past 12 months, revenues are up 6%, compressor rental units are up 21%. As a result of investing approximately $5.8 million in new rental equipment, lease revenue has increased 46% and profits from operations are up 12%. During this 12-month period the amount invested in new rental equipment was 72% greater than the previous 12 months.

Wayne Vinson, President and CEO of Natural Gas Services Group, Inc. said, "I am extremely pleased with our growth in this past year and what we have accomplished. We have employed our capital wisely to build significant value for our shareholders in the form of cash flow and asset value. Asset based value that throws off high cash flow is a very good reward versus risk for our shareholders."

Joe Dancy, Fund Manager for LSGI Advisors Inc., Dallas, TX. said, "Regardless of the future direction of natural gas prices, Natural Gas Services Group will prosper providing needed services in the compression segment." Mr. Dancy named NGS as his 2003 "Best Investment Idea" in the Dick Davis Digest published earlier this year. LSGI Fund is up 85% year to date and 131% over the last 12 months thanks in part to the performance of Natural Gas Services.

Mr. John Gay, Publisher of The Quiet Investor in a recent newsletter said, "Several recent articles talk about the natural gas dilemma in which we are finding ourselves in. Prices are double a year ago, and they may well stay this high for years to come. Natural Gas Services is in a strong growth pattern with a product superior to those now in use in a field that is in a strong growth mode. The Company has grown quickly and is positioning itself to continue that growth."
