MIDLAND, Texas May 16, 2022 - Natural Gas Services Group, Inc. (“NGS” or the “Company”) (NYSE:NGS), a leading provider of natural gas compression equipment and services to the energy industry, today announced financial results for the three months ended March 31, 2022.

"The first quarter of 2022 was the fifth consecutive quarter of rental revenue growth. While we are still facing inflationary pressures and supply chain challenges, we were pleased to see our costs decline from the fourth quarter” said Stephen C. Taylor, Chairman, President and Chief Executive Officer. “Compression rental revenue grew 4% sequentially and 12% on an annual basis, driven by both an increase in rental horsepower as well as modest pricing improvement. As mentioned last quarter, we have instituted broad price increases with the majority of our customers and those revenue increases will be reflected in our second quarter financials.”

“While producers remain conservative in capital commitments for purchased compression equipment, we continue to see steady demand for our large horsepower rental fleet,” Taylor noted. “We expect that trend to continue throughout the year, resulting in a revised capital expenditure budget of approximately $30-$35 million for fiscal year 2022.”

“We are optimistic about our opportunities in 2022,” Taylor concluded. “and we continue to believe our strong balance sheet provides meaningful flexibility to create durable value for our shareholders."

Revenue: Total revenue for the three months ended March 31, 2022 increased to $20.3 million from $18.4 million for the three months ended March 31, 2021. This increase was due to an increase in rental and sales revenues. Rental revenue increased 11.7% to $17.1 million in the first quarter of 2022 from $15.3 million in the first quarter of 2021 due to the increased deployment of rental units, primarily higher horsepower packages. As of March 31, 2022 we had 1,276 rented units (306,834 horsepower) compared to 1,265 rented units (287,914 horsepower) as of March 31, 2021. Sequentially, total revenue increased 12.8% to $20.3 million in the first quarter of 2022 compared to $18.0 million in the fourth quarter of 2021 primarily due to a $1.8 million increase in sales revenues as well as a $0.7 million increase in rental revenues during the three months ended March 31, 2022.

Gross Margins: Total gross margins increased to $2.7 million for the three months ended March 31, 2022 compared to $2.4 million for the same period in 2021. Total adjusted gross margin, exclusive of depreciation, for the three months ended March 31, 2022, increased to $8.9 million from $8.6 million for the same period ended March 31, 2021. This increase was primarily attributable to increased compressor sales and associated gross margins during the current quarter. Sequentially, total gross margin increased to $2.7 million for the three months ended March 31, 2022 compared to a negative $(1.9) million for the three months ended December 31, 2021. Excluding depreciation, total adjusted gross margin increased to $8.9 million during the first

quarter of 2022 compared to $4.3 million during the fourth quarter of 2021. This sequential increase was primarily due to higher rental margins this quarter driven by a significant reduction in costs associated with rental mobilization, commissioning, start-up and maintenance. Please see discussions of Non-GAAP Financial Measures - Adjusted Gross Margin, below.

Operating Income (Loss): Operating income for the three months ended March 31, 2022 was $382,000 compared to an operating loss of $(369,000) for the three months ended March 31, 2021. Operating income increased due to higher compressor sales margins. Similarly, operating income increased due to greater revenue and rental margins in the first quarter of 2022 to $382,000 from an $8.2 million loss during the fourth quarter of 2021.

Net Income (Loss): Net income for the three months ended March 31, 2022 was $337,000 ($0.03 per basic and diluted shares) compared to net loss of $394,000 ($(0.03) per basic and diluted shares) for the three months ended March 31, 2021. The increase in net income during the first quarter of 2022 was mainly due to increased sales margins partially offset by a decrease in rental margins. Sequentially, net income during the first quarter of 2022 of $337,000 ($0.03 per basic and diluted shares) compares to net loss of $5.6 million ($0.42 per basic and diluted shares) during the fourth quarter of 2021. This sequential improvement was primarily due to (i) a $3.1 million charge incurred in the fourth quarter of 2021 related to fleet retirements, (ii) a $3.0 million increase in rental gross margins and (iii) a $1.7 million increase in sales gross margins. These increases were partially offset by a $2.2 million reduction in income tax benefit.

Adjusted EBITDA: Adjusted EBITDA increased to $6.8 million for the three months ended March 31, 2022 from $6.5 million for the same period in 2021. This increase was primarily attributable to higher sales margins. Sequentially, adjusted EBITDA increased to $6.8 million for the three months ended March 31, 2022 from $2.3 million in the previous quarter. This increase was primarily attributable to higher rental and sales margins.

Cash flows: At March 31, 2022, cash and cash equivalents were approximately $16.4 million, while working capital was $40.2 million with no outstanding debt. For the three months of 2022, cash flows from operating activities was $5.0 million, while cash flows used in investing activities was $8.2 million. Cash flows used in investing activities included $8.2 million in capital expenditures, of which $8.1 million was dedicated to rental capital expenditures. In addition, the Company used $2.9 million in cash to repurchase 246,488 shares of common stock on the open market.

Selected data: The tables below show, for the three months ended March 31, 2022 and 2021, revenues and percentage of total revenues, along with our gross margin and adjusted gross margin (exclusive of depreciation and amortization), as well as, related percentages of revenue for each of our product lines. Adjusted gross margin is the difference between revenue and cost of sales, exclusive of depreciation.

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

Non-GAAP Financial Measure - Adjusted Gross Margin: “Adjusted Gross Margin” is defined as total revenue less cost of sales (excluding depreciation expense). Adjusted 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 expense), which are key operating components. Adjusted gross margin differs from gross margin in that gross margin includes depreciation expense. We believe adjusted gross margin is important because it focuses on the current operating performance of our operations and excludes the impact of the prior historical costs of the assets acquired or constructed that are utilized in those operations. Depreciation expense reflects the systematic allocation of historical property and equipment values over the estimated useful lives.

Adjusted gross margin has certain material limitations associated with its use as compared to gross margin. Depreciation expense is a necessary element of our costs and our ability to generate revenue. 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, adjusted gross margin should not be considered an alternative to, or more meaningful than, gross margin as determined in accordance with GAAP. Adjusted Gross margin may not be comparable to a similarly titled measure of another company because other entities may not calculate adjusted gross margin in the same manner.

The following table calculates gross margin, the most directly comparable GAAP financial measure, and reconciles it to adjusted gross margin:


	Three months ended March 31,
	2022		2021
	(in thousands)
Total revenue	20,336		$	18,397
Costs of revenue, exclusive of depreciation	(11,391)		(9,820)
Depreciation allocable to costs of revenue	(6,222)		(6,143)
Gross margin	2,723		2,434
Depreciation allocable to costs of revenue	6,222		6,143
Adjusted Gross Margin	$	8,945	$	8,577

Non-GAAP Financial Measures - Adjusted EBITDA: “Adjusted EBITDA” reflects net income or loss before interest, taxes, depreciation and amortization, non-cash stock compensation expense, impairment of goodwill, increases in inventory allowance and retirement of rental equipment. Adjusted EBITDA is a measure used by management, 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, Adjusted EBITDA gives the investor information as to the cash generated from the operations of a business. However, Adjusted 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. Adjusted EBITDA as calculated by NGS may not be comparable to Adjusted EBITDA as calculated and reported by other companies. The most comparable GAAP measure to Adjusted EBITDA is net income (loss).

The following table reconciles our net (loss) income, the most directly comparable GAAP financial measure, to Adjusted EBITDA:


	Three months ended March 31,
	2022		2021
	(in thousands)
Net (loss) income	$	337	$	(394)
Interest expense	24		1
Income tax benefit	(11)		125
Depreciation and amortization	6,061		6,297
Non-cash stock compensation expense	420		474
