MIDLAND, Texas November 5, 2015 - Natural Gas Services Group, Inc. (NGS), a leading provider of gas compression equipment and services to the natural gas industry, announces its financial results for the three and nine months ended September 30, 2015.

Revenue: Total revenue was $21.2 million, a decrease from $25.6 million, or 17%, for the three months ended September 30, 2015 compared to the same period ended September 30, 2014. This change was attributable to lower unit sales and a fall in rental revenue related to reduced activity in the upstream oil and gas industry due to low commodity prices. Total revenue decreased between consecutive quarters by $3.0 million to $21.2 million from $24.2 million, primarily due to the lower activity levels noted above. On a nine month year-to-date basis, 2014 and 2015 revenues were essentially flat with 2015 revenues of $70.2 million being one-half percent higher than 2014.

Gross Margins: Total gross margin for the three months ended September 30, 2015 decreased $1.8 million to $12.1 million from $13.9 million for the same period ended September 30, 2014. Overall gross margin percentage improved to 57% for the three months ended September 30, 2015 compared to 54% for the same period ended September 30, 2014. Sequentially, gross margin was $14.0 million for the three months ending June 30, 2015 compared to $12.1 million in the three months ended in September 30, 2015 with gross margin percentages holding in the 57-58% range. For the comparative nine months ended, total gross margin increased to $40.2 million from $39.0 million, a 3% increase.

Operating Income: Operating income for the three months ended September 30, 2015 was $3.8 million, compared to the comparative prior year`s level of $5.8 million. This decrease was due to a reduction in total revenue, primarily compressor sales revenue, but partially offset by a decrease in direct operating costs, which during the comparative periods were down 22%. Sequentially, operating income decreased to $3.8 million, for the three months ended September 30, 2015 from $5.4 million in the three month period ended June 30, 2015 primarily due to a decrease in total revenues between the periods. Total costs were down $1.6 million between the three months ended June 30, 2015 and the same period ended  September 30, 2015. Adjusted operating income in the nine months ended 2015 period was $15.0 million, down 2% compared to last year`s comparative period.
Please see discussion of Non-GAAP Financial Measures - Special Items, below.

Net Income:  Net income for the three months ended September 30, 2015 decreased to $2.6 million compared to net income of $3.9 million for the same period in 2014. This decrease was primarily driven by lower compressor sales and their gross margin in the current quarter. Sequentially, net income decreased to $2.6 million from $3.5 million. In the comparative nine months ended, adjusted net income decreased 3% to $9.8 million. Please see discussion of Non-GAAP Financial Measures - Special Items, below.

Earnings Per Share:  Comparing the third quarter of 2015 versus 2014, earnings per diluted share was 20 cents down from 30 cents. Diluted earnings per share decreased to 20 cents from 28 cents between sequential quarters.

EBITDA:  EBITDAdecreased $2.1 million to $9.4 million or 44% of revenue for the three months ended September 30, 2015 versus $11.5 million or 45% of revenue for the same three months ended September 30, 2014. EBITDA decreased approximately $1.7 million in the sequential quarters, and relative to revenue decreased to 44% from 46%. Comparing the nine months ended, EBITDA was up 3% to $32.2 million or 46% of revenue. Please see discussion of Non-GAAP Financial Measures - EBITDA, below.

Cash Flow: At September 30, 2015, cash and cash equivalents were $30.0 million with a total debt level of $417,000, all of which was classified as long term. Positive net cash flow from operating activities was $34.8 million during the nine months ended of 2015.

Special Items: During the first half of this year NGS initiated a review focused on optimization of the rental fleet and made adjustments for equipment that has been relatively underutilized; primarily related to older gas compression packages designed for dry natural gas shale operations. As a result of our review, NGS reported a non-cash, pre-tax charge of $4.5 million during the second quarter of 2015. This charge included a pre-tax charge on the retirement of rental equipment of $4.4 million. The remaining balance was related to a slight increase in bad debt and inventory allowances. The effects of these adjustments are excluded from comparisons above for second quarter 2015. Please see discussion of Non-GAAP Financial Measures - Special Items, below.

Non GAAP Financial Measures - Special Items: From time to time, management may publicly disclose certain "non-GAAP financial measures", such as adjusted net income below, in our earnings releases, financial presentations or earnings conference calls. These non-GAAP measures are not in accordance with, or a substitute for, measures prepared in accordance with GAAP, and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. Non-GAAP measures have limitations in that they do not reflect all of the amounts associated with the Company`s results of operations that would be reflected in measures determined in accordance with GAAP.

Adjusted operating income and net income from operations reflects operating and net income before the loss on retirement of rental equipment and increases in bad debt and inventory allowances, taken in the second quarter. The reconciliation of reported operating income and net income from operations to adjusted operating income and net income from operations is as follows:

	Nine months ended September 30, 2015
	(in thousands)
	Condensed
Reported operating income	$	10,504
Retirement of rental equipment and increase in allowances	4,526
Adjusted operating income	$	15,030

Commenting on third quarter 2015 results, Stephen C. Taylor, President and CEO, said:

"Looking back over the past nine months of this year compared to the same period in 2014, NGS has performed  remarkably well. Revenue, gross margin and operating income in 2015 are all within  3%  of last year`s results. Not surprisingly though, we are experiencing an inevitable sequential decline in revenue from the severe impact on our customer`s activity due to low oil and gas prices. Although price and utilization pressures are a fact of life, I am confident that we will continue to compete effectively, maintain our margins and generate significant levels of free cash."

Selected data: The table below shows revenues, percentage of total revenues, gross margin, exclusive of depreciation, amortization, and gross margin percentage of each of our business lines for the three and nine months ended September 30, 2015 and 2014.  Gross margin is the difference between revenue and cost of sales, exclusive of depreciation and amortization.

(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 - EBITDA" below.

Non GAAP Financial Measures - EBITDA: "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 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:

Gross margin	$	12,056			$	13,895			$	40,245			$	38,963

"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 of 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.
