MIDLAND, Texas May 15, 2023 (GLOBE NEWSWIRE) 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, 2023.

Commenting on the quarter, Stephen C. Taylor our Interim President and Chief Executive Officer, added “This quarter marked the ninth quarter in a row of rental revenue growth. For the current sequential quarters, rental revenue alone grew almost 11% while higher rental and sales revenues grew total revenues by 18%. Adjusted rental gross margins slipped 2% due to higher field expenses and a one-time non-cash adjustment, but our total adjusted gross margin increased 4% sequentially. SG&A declined 4% and our bottom-line net income had a positive swing of almost a million dollars from last quarter as we posted positive GAAP earnings”.

“As mentioned in the last earnings call, NGS closed on a substantial line of credit from our bank at the end of February,” Taylor noted. “This was to fund the additional high horsepower equipment we have already contracted as we continue to execute on our growth plan. NGS had a solid and growing quarter. We have added more committed contracts over the past couple of months, our utilization continues to increase and pre-contracted activity remains at a high level for the rest of the year resulting in an estimated capital expenditure budget of approximately $150 million for the fiscal year 2023 almost of all of which will support project already under contracts with customers.”

Revenue: Total revenue for the three months ended March 31, 2023 increased to $26.6 million from $20.3 million for the three months ended March 31, 2022. This increase was due primarily to an increase in rental revenues. Rental revenue increased 32.7% to $22.7 million in the first quarter of 2023, from $17.1 million in the first quarter of 2022 due to higher horsepower packages and modest pricing improvements. As of March 31, 2023, we had 1,245 rented units (335,314 horsepower) compared to 1,276 rented units (306,834 horsepower) as of March 31, 2022, reflecting an 9.3% increase in average horsepower deployed. Sequentially, total revenue increased 18.2% to $26.6 million in the first quarter of 2023 compared to $22.5 million in the fourth quarter of 2022 primarily due to increases in both rental revenues and sales revenues during the three months ended March 31, 2023.

Gross Margins: Total gross margins increased to $5.1 million for the three months ended March 31, 2023, compared to $3.0 million for the same period in 2022. Total adjusted gross margin, exclusive of depreciation, for the three months ended March 31, 2023, increased to $11.1 million from $8.9 million for the same period ended March 31, 2022. This increase was primarily attributable to increased rental revenues and associated gross margins during the current quarter. Sequentially, total gross margin increased to $5.1 million for the three months ended March 31, 2023, compared to $4.9 million for the three months ended December 31, 2022. Excluding depreciation, total adjusted gross margin increased to $11.1 million during the first quarter of 2023 compared to $10.7 million during the fourth quarter of 2022. This sequential increase was primarily due to higher compressor sales.

Operating Income: Operating income for the three months ended March 31, 2023 was $402,000 compared to an operating income of $382,000 for the three months ended March 31, 2022. Operating income increased in the first quarter of 2023 to $402,000 from an operating loss of $316,000 during the fourth quarter of 2022.

Net Income: Net income for the three months ended March 31, 2023, was $370,000 ($0.03 per basic share) compared to net income of $337,000 ($0.03 per basic share) for the three months ended March 31, 2022. The increase in net income during the first quarter of 2023 was mainly due to increased rental margins partially offset by an increase in selling, general and administrative expenses. Sequentially, net income during the first quarter of 2023 was $370,000 ($0.03 per basic share) compared to net loss of $756,000 ($0.06 per basic share) during the fourth quarter of 2022. This sequential improvement of $1.1 million was primarily due to higher rental activity and associated gross margin and a non cash charge for fleet retirements in the fourth quarter of 2022.

Adjusted EBITDA: Adjusted EBITDA increased to $7.8 million for the three months ended March 31, 2023, from $6.8 million for the same period in 2022. This increase was primarily attributable higher adjusted gross margins. Sequentially, adjusted EBITDA was flat at $7.8 million for the three months ended March 31, 2023, and in the previous quarter.

Cash flows: At March 31, 2023, cash and cash equivalents were approximately $7.4 million, while working capital was $17.6 million with $61.0 million outstanding on our revolving credit facility. For the three months of 2023, cash flows from operating activities were $18.2 million, while cash flows used in investing activities was $47.8 million. Cash flows used in investing activities included $47.8 million in capital expenditures, of which $47.0 million was dedicated to rental capital expenditures.

(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,
	2023		2022
	(in thousands)
Total revenue	$	26,620	$	20,336
Costs of revenue, exclusive of depreciation	(15,491)		(11,391)
Depreciation allocable to costs of revenue	(6,015)		(5,912)
Gross margin	5,114		3,033
Depreciation allocable to costs of revenue	6,015		5,912
Adjusted Gross Margin	$	11,129	$	8,945

Non-GAAP Financial Measures - Adjusted EBITDA: “Adjusted EBITDA” reflects net income or loss before interest, taxes, depreciation and amortization, non-cash stock compensation expense, severance expenses, 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 income, the most directly comparable GAAP financial measure, to Adjusted EBITDA:
