NATURAL GAS SERVICES GROUP ANNOUNCES DILUTED EARNINGS PER SHARE OF

$0.29 FOR THE QUARTER AND $1.03 FOR THE YEAR ENDED DECEMBER 31, 2012

44% Increase in Revenues and 30% Increase in Net Income for 2012

MIDLAND, Texas March 14, 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 and year ended December 31, 2012.

Revenue: Total revenue increased from $65.2 million to $93.7 million, or 43.8%, for the year ended December 31, 2012, compared to the same period ended December 31, 2011. This was primarily the result of a 135.9% increase in sales revenue and an increase in rental revenue of 16.2%. Total revenues were up 22.1% between the third and the fourth quarters of 2012 to $23.2 million due to a surge in compressor sales orders delivered in the fourth quarter.

Gross Margins: Total gross margin increased 26% from $34.8 million in the year ending December 31, 2011 to $43.8 million for the twelve months ended December 31, 2012. Gross margin percentage decreased to 46.7% from 53.4% in the comparative full-year period due to a revenue mix shift from rentals and flares to compressor sales, a relatively lower margin product. Gross margins grew 12.3% sequentially and 16% in the fourth quarter comparative periods.

Operating Income: Operating income for the year ended December 31, 2012 was $20.2 million, up 36% from the comparative prior year's level of $14.9 million. The fourth quarter of 2012 saw operating income increase 30% compared to the third quarter of 2012 and 18% compared to the same quarter in 2011.

Net Income: Net income for the twelve months of 2012 increased 30% to $12.7 million, when compared to net income of $9.8 million for the same period in 2011. The increase is largely due to rental fleet and revenue growth and improved sales of compressors and flares. Net income grew 37% in the fourth quarter when compared to the third quarter of 2012 and was up 18% when matched against the fourth quarter of 2011.

Earnings per share: Comparing 2012 versus 2011, earnings per diluted share increased to $1.03 from $0.80 or 28.8%. Earnings per diluted share for the three months ended December 31, 2012 grew 16% to $0.29 from $0.25 in the fourth quarter of 2011 and 38.1% compared to the previous quarter of 2012.

EBITDA: EBITDA increased 21.1% to $35.9 million for the year ended December 31, 2012 versus $29.7 million for the year ended December 31, 2011. EBITDA increased 17.5% to $9.6 million for the fourth quarter of 2012 when compared to the third quarter of 2012 and 12.9% when compared to the fourth quarter of 2011. Please see discussion of Non-GAAP measures in this release.

Cash flow: At December 31, 2012, cash and cash equivalents were approximately $28.1 million; working capital was $50.3 million with a total debt level of $0.9 million, which was classified as long term. Positive net cash flow from operating activities was approximately $35.4 million during 2012.

Commenting on 2012 results, Stephen C. Taylor, President and CEO, said:

"NGS had a very solid, growth year in 2012 and we are pleased with our financial and operational results. Financially, our revenues continued to increase and, in fact, we set a historical high this year for both total and rental revenues. Sales revenues, although not at record levels, was a significant driver of our growth this year and we posted the best year we've had since 2009. Overall, total revenues increased 44%, operating income was up 36% and earnings per share grew 29%. Operationally, our rental fleet continued to expand as did our movement into the oil and liquids oriented plays and we consider ourselves the growth leader in the wellhead segment of that market. We are now operating in just about all major oil-shale basins and have been continuing our penetration into each. We think our markets look favorable, and we look forward to continued growth in 2013."

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 year ended December 31, 2012 and 2011. Gross margin is the difference between revenue and cost of sales, exclusive of depreciation.

(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:



(in thousands of dollars)	Three Months Ended					Twelve Months Ended
	December 31,					December 31,
	2012		2011			2012			2011
Net income	$	3,570	$	3,024		$	12,685		$	9,760
Interest expense	5		7			18			55
Provision for income taxes	1,899		1,741			7,526			5,869
Depreciation and amortization	4,144		3,724			15,707			13,994
EBITDA	9,618		8,496			35,936			29,678
Other operating expenses	1,777		1,494			7,893			5,910
Other income	49		(106		)	(14		)	(824		)
Gross margin	$	11,444	$	9,884		$	43,815		$	34,764

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.
