NGS Reports Earnings of 32 cents per Diluted Share in the First Quarter 2013

Double-Digit Percentage Increases Year-over-Year and Sequentially

MIDLAND, Texas May 9 , 2013 - Natural Gas Services Group, Inc. (NYSE:NGS), a leading provider of gas compression equipment and services to the natural gas industry, announces its financial results for the three months ended March 31, 2013.

Revenue: Total revenue was $24.0 million, a decrease from $26.4 million, or 9%, for the three months ended March 31, 2013, compared to the same period ended March 31, 2012. This decrease is due to the first half of a non-recurring sale of units from our fleet during the first quarter of 2012. Rental revenues increased 17% in the same year-over-year period and 7% sequentially. Total revenues increased 2% between the fourth quarter of 2012 and this current period.

Gross Margins: Total gross margin increased 9% from $11.2 million for the period ended March 31, 2012 to $12.2 million for the period ended March 31, 2013. Sequentially, gross margin increased 7% from $11.4 million to $12.2 million. Overall gross margin percentage was 51% for the three months ended March 31, 2013, compared to 43% for the same period ended March 31, 2012. This increase is primarily the result of a mix shift to higher margin rentals and flare sales from lower margin compressor sales, although we did also experience greater profitability in our compressor sales line.

Operating Income: Operating income for the three months ended March 31, 2013 was $6.1 million, up 9% from the comparative prior year's level of $5.6 million. This increase was primarily driven by a shift in our product mix and generally higher margins. Sequentially, operating income increased 11% to $6.1 million for the three months ended March 31, 2013 from $5.5 million.

Net Income: Net income for the three months ended March 31, 2013 increased 14% to $4.0 million, when compared to net income of $3.5 million for the same period in 2012. Net income margins for the three months ended March 31, 2013 increased to 17% from 13% for the three months ended March 31, 2012. This increase was mainly the result of the shift toward compressor rentals in this period. Net income increased 12% in sequential quarters from $3.6 million to $4.0 million.

Earnings per share: Comparing the three months of 2013 versus 2012, earnings per diluted share improved to 32 cents from 29 cents, or 10%. Diluted earnings increased 10% per share, to 32 cents from 29 cents, between sequential quarters.

EBITDA: EBITDA increased 13% to $10.7 million or 45% of revenue for the three months ended March 31, 2013 versus $9.4 million or 36% of revenue for the same three months ended March 31, 2012. Please see discussion of Non-GAAP measures.

Cash flow: At March 31, 2013, cash and cash equivalents were approximately $31.3 million; working capital was $53.1 million with a total debt level of $897 thousand, all of which was classified as non-current. Positive net cash flow from operating activities was approximately $10.9 million during the first three months of 2013 compared to $14.8 million for the same period in 2012. The changes in operating cash flow relate exclusively to normal variations in our working capital accounts.

Commenting on first quarter 2013 results, Stephen C. Taylor, President and CEO, said:

"Although we had some revenue variability this quarter compared to the year ago quarter due to a non-recurring sale, we were successful in replacing a good amount of that revenue and, most importantly, increasing our gross margin, operating income and net income profitability. Netting out the effect of the non-recurring sale, we have continued to grow all our business lines with our core rental compression business continuing to be especially vibrant as demonstrated by the 17% year-over-year and 7% sequential revenue increases. Our rental fleet utilization has increased to 79% and we now have over 35% of the rental compressor fleet installed in oil or liquids oriented basins. All these factors reinforce the position we hold in the market as a premier wellhead compression provider."

Selected data: The table below shows revenues, percentage of total revenues, gross margin, exclusive of depreciation, and gross margin percentage of each business segment for the three months ended March 31, 2013 and 2012.

(1) For a reconciliation of gross margin to its most directly comparable financial measure calculated and presented in accordance with GAAP, please read “Non-GAAP Financial Measures” below.

Non GAAP Measures: “EBITDA” reflects net income or loss before interest, taxes, depreciation and amortization. EBITDA is a measure used by analysts and investors as an indicator of operating cash flow since it excludes the impact of movements in working capital items, non-cash charges and financing costs. Therefore, EBITDA gives the investor information as to the cash generated from the operations of a business. However, EBITDA is not a measure of financial performance under accounting principles generally accepted in the United States of America (“GAAP”), and should not be considered a substitute for other financial measures of performance. EBITDA as calculated by NGS may not be comparable to EBITDA as calculated and reported by other companies. The most comparable GAAP measure to EBITDA is net income. The reconciliation of net income to EBITDA and gross margin is as follows:



	Three months ended March 31,
	(dollars in thousands)
	2013			2012
Net income	$	3,994		$	3,508
Interest expense	30			3
Provision for income taxes	2,448			2,150
Depreciation and amortization	4,238			3,787
EBITDA	$	10,710		$	9,448
Other operating expenses	1,846			1,810
Other income	(335		)	(39		)
Gross margin	$	12,221		$	11,219

"Gross margin" is defined as total revenue less cost of sales (excluding depreciation and amortization expense). Gross margin is included as a supplemental disclosure because it is a primary measure used by management as it represents the results of revenue and cost of sales (excluding depreciation and amortization expense), which are key operating components. Depreciation expense is a necessary element of costs and the ability to generate revenue and selling, general and administrative expense is a necessary cost to support operations and required corporate activities. Management uses this non-GAAP measure as a supplemental measure to other GAAP results to provide a more complete understanding the company's performance. As an indicator of operating performance, gross margin should not be considered an alternative to, or more meaningful than, net income as determined in accordance with GAAP. Gross margin may not be comparable to a similarly titled measure of another company because other entities may not calculate gross margin in the same manner.
