Natural Gas Services Group, Inc. (the "Company", “NGS”, "Natural Gas Services Group", "we" or "our") (a Colorado corporation), is a leading provider of natural gas compression equipment, technology and services to the energy industry. The Company manufactures, fabricates, rents, sells and maintains natural gas compressors systems for oil and natural gas production and plant facilities. NGS is headquartered in Midland, Texas, with fabrication facilities located in Tulsa, Oklahoma and Midland, Texas, and service facilities located in major oil and natural gas producing basins in the U.S. The company also has increasingly used third-party fabricators as well.

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company, its subsidiary, NGSG Properties, LLC and the rabbi trust associated with the Company's deferred compensation plan. All significant intercompany accounts and transactions for the periods presented have been eliminated in consolidation.

These financial statements include all adjustments, consisting of only normal recurring adjustments, which are necessary to make our financial position at September 30, 2023 and the results of our operations for the three and nine months ended September 30, 2023 and 2022 not misleading. Some adjustments may cause the prior year number in these financial statements to differ from the prior year interim financial statements. As permitted by the rules and regulations of the Securities and Exchange Commission (the "SEC"), the accompanying condensed consolidated financial statements do not include all disclosures normally required by generally accepted accounting principles in the United States of America (GAAP). These financial statements should be read in conjunction with the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2022 on file with the SEC. In our opinion, the condensed consolidated financial statements are a fair presentation of the financial position, results of operations, changes in stockholders' equity and cash flows for the periods presented.

The results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the results of operations to be expected for the full fiscal year ending December 31, 2023.

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers ("ASC 606"), except for rental revenue as discussed below. Under ASC 606, revenue is measured based on a consideration specified in a customer’s contract, excluding any sale incentives and taxes collected on behalf of third parties (i.e. sales and property taxes). Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration that we expect to receive for those goods or services. To recognize revenue, we (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, we satisfy the performance obligation(s). Shipping and handling costs incurred are accounted for as fulfillment costs and are included in cost of revenues in our condensed consolidated statements of operations.

The following is a description of principal activities from which the Company generates its revenue:

Rental Revenue. The Company generates revenue from renting compressor systems to our customers. These contracts, which all qualify as operating leases under ASC Topic 842, Leases (ASC 842), may also include a fee for servicing the compressor during the rental contract period. Our rental contracts typically range from six to 24 months, with our larger horsepower compressors having contract terms of up to 60 months. Our revenue is recognized over time, generally monthly, in accordance with payment terms under the contract. After the terms of the contract have expired, a customer may renew their contract or continue renting on a monthly basis thereafter. In accordance with ASC 842, we have applied the practical expedient ASC 842-10-15-42A, which allows the Company to combine lease and non-lease components.

Sales Revenue. The Company generates revenue by the sale of custom/fabricated compressors, and parts, as well as, exchange/rebuilding customer owned compressors and sale of used rental equipment.

Custom/fabricated compressors - The Company designs and fabricates compressors based on the customer’s specifications outlined in their contract. Though the equipment being built is customized by the customer, control under these contracts does not pass to the customer until the compressor package is complete and shipped, or in accordance with a bill and hold arrangement, the customer accepts title and assumes the risk and rewards of ownership. We request some of our customers to make progressive payments as the product is being built; these payments are recorded as a contract liability on the Deferred Income line on the condensed consolidated balance sheet until control has been transferred. These contracts also may include an assurance warranty clause to guarantee the product is free from defects in material and workmanship for a set duration of time; this is a standard industry practice and is not considered a performance obligation.

From time to time we recognize revenue when manufacturing is complete and the equipment is ready for shipment. At the customer’s request, we will bill the customer upon completing all performance obligations, but before shipment. The customer will formally request that we ship the equipment per their direction from our manufacturing facility or the third-party fabrication site at a later specified date and that we segregate this equipment from our finished goods, such that this equipment is not available to fill other orders. Per the customer’s agreement change of control is passed to the customer once the equipment is complete and ready for shipment. We have operated using bill and hold agreements with certain customers for many years, with consistent and satisfactory results for both the customer and us. The credit terms on these agreements are consistent with the credit terms on all other sales. All control is maintained by the customer and there are no exceptions to the customer’s commitment to accept and pay for the manufactured equipment. There was no revenue recognized for bill and hold arrangements for the nine months ended September 30, 2023 or 2022.

Parts - Revenue is recognized after the customer obtains control of the parts. Control is passed either by the customer taking physical possession or the parts being shipped. The amount of revenue recognized is not adjusted for expected returns, as our historical part returns have been de minimis.

Exchange or rebuilding customer owned compressors - Based on the contract, the Company will either exchange a new/rebuilt compressor for the customer’s malfunctioning compressor or rebuild the customer’s compressor. Revenue is recognized after control of the replacement compressor has transferred to the customer based on the terms of the contract, i.e., by physical delivery, delivery and installment, or shipment of the compressor.

Used compressors - From time to time, a customer may request to purchase a used compressor out of our rental fleet. Revenue from the sale of rental equipment is recognized when the control has passed to the customer based on the terms of the contract, i.e., when the customer has taken physical possession or the equipment has been shipped.

Aftermarket Services. The Company provides routine or call-out services on customer owned equipment. Revenue is recognized after services are rendered. The company also provides freight and commissioning services for new compressor sets.

Payment terms for sales revenue and aftermarket services discussed above are generally 30 to 60 days, although terms for specific customers can vary. Also, transaction prices are not subject to variable consideration constraints.

The following table shows the Company's revenue disaggregated by product or service type for the three and nine months ended September 30, 2023 and 2022:

			Three months ended September 30,												Nine months ended September 30,

As of September 30, 2023 and December 31, 2022, we had the following receivables and deferred income from contracts with customers:

The Company recognized sales revenues of $37 thousand for the nine months ended September 30, 2023 that was included in deferred income at the beginning of 2023.

The increase in accounts receivable and decrease in deferred income were primarily due to normal timing differences between our performance and the customers’ payments.

As of September 30, 2023, the Company had no deferred revenue related to unsatisfied performance obligations.

The Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. These costs are included in selling, general and administrative expenses on our condensed consolidated statements of operations.

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases, and operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Valuation allowances are established to reduce deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized. To the extent we establish a valuation allowance or increase this allowance in a period, we include an expense in the tax provision in our condensed consolidated statements of operations.

We account for uncertain tax positions in accordance with guidance in ASC 740, which prescribes the minimum recognition threshold a tax position taken or expected to be taken in a tax return is required to meet before being recognized in the condensed consolidated financial statements. Tax benefits are recognized only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50% likely to be realized upon settlement. A liability for unrecognized tax benefits is recorded for any tax benefits claimed in our tax returns that do not meet these recognition and measurement standards. We have no liabilities for uncertain tax positions as of September 30, 2023.

Our policy regarding income tax interest and penalties is to expense those items as interest expense and other expense, respectively.

Effective January 1, 2023, the Company began capitalizing interest from external borrowings on significant expenditures for the fabrication of its natural gas compressor equipment until such projects are ready for their intended use. Capitalized interest is added to the cost of the underlying asset and is amortized over the useful lives of the assets in the same manner as the underlying assets. For the nine months ended September 30, 2023, the Company capitalized interest aggregating approximately $4.1 million.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (ASC Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments to ASC Topic 326 require immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets, including trade receivables. For companies that qualify as smaller reporting companies, the amendments in this update are effective for interim and annual periods beginning after January 1, 2023. We adopted ASU 2016-13 on January 1, 2023. The adoption did not result in any material change to our financial statements. There were no other recent accounting pronouncements during the nine months ended September 30, 2023 that are expected to have a material impact on our financial statements.

Our inventory, net of allowance for obsolescence of $40,000 at September 30, 2023 and $120,000 at December 31, 2022, consisted of the following amounts:

Our long-term inventory consists of raw materials that remain viable but that the Company does not expect to sell or use within one year.

We routinely review our inventory allowance balance to account for slow moving or obsolete inventory costs that may not be recoverable in the future.

A summary of our inventory allowance is as follows:

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") was enacted in response to the economic impact caused by the COVID-19 pandemic. The CARES Act allowed NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid federal income taxes. The Company generated significant NOLs during 2018 and 2019, and has filed amended returns to carryback these losses for five years. Accordingly, during 2020, the Company recorded a federal income tax receivable of $15.0 million and an increase to its deferred income tax liability of $10.1 million on its condensed consolidated balance sheet. During the third quarter of 2020, the Company received refunds totaling $3.9 million related to its 2018 NOLs, which reduced its federal income tax receivable to $11.5 million on its condensed consolidated balance sheet as of September 30, 2023 and December 31, 2022.

Our rental equipment and associated accumulated depreciation as of September 30, 2023 and December 31, 2022, respectively, consisted of the following:

We evaluated our rental equipment for potential material impairment as of September 30, 2023, and determined that no such impairment existed as of that date.

Our long-term debt consists of the following:

On May 11, 2021, we entered into a five-year senior secured revolving credit agreement ("Credit Agreement") with Texas Capital Bank, National Association (the "Lender") with an initial commitment of $20 million and an accordion feature that would increase the maximum commitment to $30 million, subject to collateral availability. At December 31, 2022, we had $25 million outstanding under the Credit Agreement with a weighted average interest rate of 7.32%.

On February 28, 2023, we replaced our Credit Agreement by entering into a five-year senior secured revolving credit agreement (“Amended and Restated Credit Agreement”) with Texas Capital Bank, as administrative agent (the “Lender”), TCBI Securities, Inc., as joint lead arranger and sole book runner and Bank of America, N.A., as joint lead arranger, with an initial commitment of $175 million as of the closing date. Subject to collateral availability, we also have a right to request from the Lender, on an uncommitted basis, an increase of up to $125 million on the aggregate commitment; provided, however, the aggregate commitment amount is not permitted to exceed $300 million. The maturity date of the Amended and Restated Credit Agreement is February 28, 2028. The obligations under the Amended and Restated Credit Agreement are secured by a first priority lien on most of our assets, including inventory and accounts receivable as well as a variable number of our leased compressor equipment.

Borrowing Base. At any time before the maturity of the Amended and Restated Credit Agreement, we may draw, repay and re-borrow amounts available under the borrowing base up to the maximum aggregate availability discussed above. Generally, the borrowing base equals the sum of (a) 85% of eligible accounts receivable owed to the Company, plus (b) 50% of the eligible inventory, valued at the lower of cost or market value at such time, subject to a cap of the component not to exceed $2.5 million, plus (c) the lesser of (i) 95% of the net book value of the compressors that the Lender has determined are eligible for the extension of credit, valued at the lower of cost or market value with depreciation not to exceed 25 years, at such time and (ii) 80% of the net liquidation value percentage of the net book value of the eligible compressors that the Lender has determined are eligible for the extension of credit, valued at the lower of cost or market value with depreciation not to exceed 25 years, at such time, plus (d) 80% of the net book value, valued at the lower cost (excluding any costs for capitalized interest or other non-cash capitalized costs) or market of the eligible new compressor fleet, minus (e) any required availability reserves determined by the Lender in its sole discretion. The Lender may adjust the borrowing base components if the material deviations in the collateral are discovered in the future audits of the collateral. At September 30, 2023, our borrowing base was approximately $175 million.

Interest and Fees. Under the terms of the Amended and Restated Credit Agreement, we have the option of selecting the applicable variable rate for each revolving loan, or portion thereof, of either (a) the Base Rate (as defined below) plus the Applicable Margin, or (b) in the case of a Term SOFR ("Secured Overnight Financing Rate") Loan, the Adjusted Term SOFR rate plus the Applicable Margin. "Base Rate" means, for any day, a rate of interest per annum equal to the highest of (a) the prime rate for such a day; (b) the sum of the federal funds rate for such day plus 0.50%; and (c) the Adjusted Term SOFR for such day plus 1.00%. The Applicable Margin is determined based upon the leverage ratio as set forth in the most recent compliance certificate received by the Lender for each fiscal quarter from time to time pursuant to the Amended and Restated Credit Agreement. Depending on the leverage ratio, the Applicable Margin can be 2.00% to 2.75% for Base Rate Loans (as defined in Amended and Restated Credit Agreement) and 3.00% to 3.75% for Term SOFR Loans and for requested letters of credit. In addition, we are required to pay a monthly commitment fee on the daily average unused amount of the commitment while the Amended and Restated Credit Agreement is in effect at an annual rate equal to 0.50% of the unused commitment amount. Accrued interest is payable monthly on outstanding principal amounts and unused commitment fee, provided that accrued interest on Term SOFR Loans is payable at the end of each interest period, but in no event less frequently than quarterly.

Covenants. The Amended and Restated Credit Agreement contains customary representations and warranties, as well as covenants which, among other things, condition or limit our ability to incur additional indebtedness and liens; enter into transactions with affiliates; make acquisitions in excess of certain amounts; pay dividends; redeem or repurchase capital stock or senior notes; make investments or loans; make negative pledges; consolidate, merge or effect asset sales; or change the nature of our business. In addition, we are subject to certain financial covenants during certain trigger periods in the Amended and Restated Credit Agreement that require us to maintain (i) a leverage ratio, as defined, lesser than or equal to 3.50 to 1.00 as of the last day of each fiscal quarter thereafter and (ii) a fixed charge coverage ratio greater than or equal to 1.25 to 1.00 as of the last day of each fiscal quarter.

Events of Default and Acceleration. The Amended and Restated Credit Agreement contains customary events of default for credit facilities of this size and type, and includes, without limitation, payment defaults; defaults in performance of covenants or other agreements contained in the Amended and Restated Credit Agreement and the other transaction documents; inaccuracies in representations and warranties; certain defaults, termination events or similar events; certain defaults with respect to any other Company indebtedness in excess of $1.0 million; certain bankruptcy or insolvency events; the rendering of certain judgments in excess of $1.0 million; certain ERISA events; certain change in control events and the defectiveness of any liens under the secured revolving credit agreement.

Obligations outstanding under the Amended and Restated Credit Agreement may be accelerated upon the occurrence of an event of default.

As of September 30, 2023, we were in compliance with all financial covenants in our Amended and Restated Credit Agreement. As of September 30, 2023, we had approximately $128 million outstanding under our Amended and Restated Credit Agreement with a weighted average interest rate of 8.98%. At September 30, 2023, we had approximately $47 million available for borrowing under the Amended and Restated Credit Agreement, subject to borrowing base determination.

Item 2.   Management’s Discussion and Analysis of Financial Condition and Results of Operations

The discussion and analysis of our financial condition and results of operations are based on, and should be read in conjunction with, our condensed consolidated financial statements and the related notes included elsewhere in this report and in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC (the "Annual Report").

This report and our Annual Report, as amended, contain certain forward-looking statements, within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, as amended, and information pertaining to us, our industry and the oil and natural gas industry that is based on the beliefs of our management, as well as assumptions made by and information currently available to our management. All statements, other than statements of historical facts contained in this report as well as our Annual Report, including statements regarding our future financial position, growth strategy, budgets, projected costs, plans and objectives of management for future operations, are forward-looking statements. We use the words “may,” “will,” “expect,” “anticipate,” “estimate,” “believe,” “continue,” “intend,” “plan,” “budget” and other similar words to identify forward-looking statements. You should read statements that contain these words carefully and should not place undue reliance on these statements because they discuss future expectations, contain projections of results of operations or of our financial condition and/or state other “forward-looking” information. We do not undertake any obligation to update or revise publicly any forward-looking statements. Although we believe our expectations reflected in these forward-looking statements are based on reasonable assumptions, no assurance can be given that these expectations or assumptions will prove to have been correct.

Please read Item 1A, Risk Factors, in our Annual Report, as it contains important factors that could cause actual results to differ materially from the expectations reflected in the forward-looking statements.

We fabricate in-house and through third-party contractors, natural gas compressors and related equipment which we rent and sell to customers. Our primary focus is on the rental of natural gas compressors. Our rental contracts typically provide for initial terms of 6 to 24 months, with our larger horsepower units having contract terms of up to 60 months. After the initial term of our rental contracts, many of our customers have continued to rent our compressors on a month-to-month basis. Rental amounts are billed monthly in advance and include maintenance of our rented compressors. As of September 30, 2023, we had 1,233 natural gas compressors totaling 400,727 horsepower rented to 78 customers compared to 1,196 natural gas compressors totaling 305,953 horsepower rented to 77 customers at September 30, 2022.

We also fabricate in-house and through third-party contractors, natural gas compressors for sale to our customers, designing compressors to meet unique specifications dictated by well pressures, production characteristics, and particular applications for which compression is sought. Fabrication of compressors involves our purchase of engines, compressors, coolers, and other components, and assembly by us or third-party contractors of these components on skids for delivery to customer locations. The major components of our compressor packages are acquired through periodic purchase orders placed with third-party suppliers on an “as needed” basis, which presently require lead times between three to six months with delivery dates scheduled to coincide with our estimated production schedules. Although we do not have formal continuing supply contracts with any major supplier, we believe we have adequate alternative sources available. Recent inflationary pressures have created price increases in both major and minor components for our compressors as well as longer than normal lead times for such components. To date, generally we have been able to increase our rental rates and sales prices proportionally; however, if cost increases continue and we are no longer able to increase our rental rates and sales prices such an event could have a material adverse effect on the results of our operations and financial condition.

We also manufacture a proprietary line of compressor frames, cylinders and parts, known as our CiP (Cylinder-in-Plane) product line. We use finished CiP component products in the fabrication of compressor units for sale or rental by us or sell the finished component products to other compressor fabricators. To provide customer support for our compressor sales businesses, we stock varying levels of replacement parts at our Midland, Texas facility and at field service locations. We also provide an exchange and rebuild program for screw compressors and maintain an inventory of new and used compressors to facilitate this business.

We provide service and maintenance to our customers under written maintenance contracts or on an as-required basis in the absence of a service contract. Maintenance agreements typically have terms of six months to one year and require payment of a monthly fee.

The oil and natural gas equipment rental and services industry is cyclical in nature. The most critical factor in assessing the outlook for the industry is the worldwide supply and demand for oil and natural gas and the corresponding changes in commodity prices. As demand and prices increase, oil and natural gas producers typically increase their capital expenditures for drilling, development and production activities, although recent equity capital constraints and demands from institutional investors to keep spending within operating cash flow have meaningfully restrained capital expenditure budgets of domestic exploration and production companies. Generally, increased capital expenditures ultimately result in greater revenues and profits for service and equipment companies.

In general, we expect our overall business activity and revenues to track the level of activity in the oil and natural gas industry, with changes in crude oil and condensate production and consumption levels and prices affecting our business more than changes in domestic natural gas production and consumption levels and prices. In recent years we have increased our rentals and sales in unconventional oil shale plays, which are more dependent on crude oil prices. With this shift towards oil production, the demand for overall compression services and products is driven by two general factors: an increased focus by producers on artificial lift applications, e.g., production enhancement with compression assisted gas lift; and declining reservoir pressure in maturing natural gas producing fields, especially unconventional production. These types of applications have historically been serviced by wellhead size compressors, and continue to be, but there has also been an economic move by our customers towards centralized drilling and production facilities, which has increased the market need for larger horsepower compressor packages. We recognized this need in recent years and have been shifting our cash and fabrication resources towards designing, fabricating and renting gas compressor packages that range from 400 horsepower up to 2,500 horsepower. While this is a response to market conditions and trends, it also provides us with the opportunity to compete as a full-line compression provider. In addition, recent heightened focus on the emissions profile of our customers has created a shift in demand from natural gas powered compression to electric motor compression in areas where the electric infrastructure can accommodate the energy demands of these units.

We typically experience a decline in demand during periods of low crude oil and natural gas prices. During the first quarter of 2020, we saw a substantial decline in the prices for oil and natural gas. Commodity prices stabilized somewhat during 2021 and increased in the first half of 2022 and declined in the second half of 2022 and began increasing so far in 2023. Historically, activity levels of exploration and production companies have been dependent on commodity prices. However, recent capital market focus on cash returns from exploration and production companies has restricted capital spending below levels that have historically been observed during higher commodity price environments. Generally, though, we believe that production activities (in which we are involved) will fare better than drilling activity. This is reflected in both the stability of our rental revenues, which is driven by production activities, and the volatility of our compressor sales, which tends to fluctuate with customers' capital allocations. As such, we still expect compressor sales to be low for the remainder of 2023, as exploration and production companies have elected to rent compression units rather than allocating capital dollars to purchase new compression.

The table below shows our revenues and percentage of total revenues of each of our product lines for the three months ended September 30, 2023 and 2022.

Total revenue increased 42.3% to $31.4 million for the three months ended September 30, 2023 compared to $22.0 million for the three months ended September 30, 2022. This increase was primarily a result of higher rental revenue (48.7% increase) during 2023.

Rental revenue increased to $27.7 million for the three months ended September 30, 2023 compared to $18.6 million for the same period in 2022. This increase during the third quarter of 2023 was attributable to (i) an increase in high horsepower compression rentals as these units carry a higher rental revenue rate than our lower horsepower units and (ii) $0.3 million in rental rate increases across a portion of our fleet intended to offset inflationary pressures related to the costs of our rental fleet.

As of September 30, 2023, we had 1,947 compressor packages in our fleet, down from 1,976 units at September 30, 2022 due to the retirement of units during the fourth quarter of 2022 and the disposition of a small number of compressors from the fleet during this year. The Company's total unit horsepower increased to 509,198 horsepower at September 30, 2023 compared to 423,658 horsepower at September 30, 2022, due to additions to the Company's fleet of 59 high horsepower compressors over the past 12 months. As of September 30, 2023, we had 1,233 natural gas compressors with a total of 400,727 horsepower rented to 78 customers, compared to 1,196 natural gas compressors with a total of 305,953 horsepower rented to 77 customers as of September 30, 2022. As a result, our total rented horsepower as of September 30, 2023 increased by 31.0% over the last twelve months. Our rental fleet had unit utilization as of September 30, 2023, and 2022, respectively, of 63.3% and 60.5%, and our horsepower utilization for the same dates increased to 78.7% from 72.2%. Our total rented horsepower increased by 31.0% contrasted against a 3.1% increase in total rented units. This illustrates the growing demand for our high horsepower units while the demand for our smaller and medium horsepower units has not recovered in line with recent commodity price increases.

Sales revenue decreased (54.2)% to $1.4 million for the three months ended September 30, 2023 compared to $3.1 million for the three months ended September 30, 2022. This decrease is primarily attributable to lower compressor sales during the third quarter of 2023 compared to the same period in 2022. Sales are subject to fluctuations in timing of industry activity related to our customers' capital projects and, as such, can vary substantially between periods.

Aftermarket service revenue increased 590% to $2.3 million for the three months ended September 30, 2023 compared to $0.3 million for the three months ended September 30, 2022. This increase is primarily attributable to freight and commissioning of high horsepower units during the three months ended September 30, 2023.

Cost of rentals increased to $13.5 million during the three months ended September 30, 2023 compared to $10.0 million during the three months ended September 30, 2022. This 34.8% increase in costs of rentals is primarily due to more rented horsepower during 2023.

Cost of sales decreased 27.7% to $1.5 million during the three months ended September 30, 2023 compared to $2.1 million during the three months ended September 30, 2022. This decrease was primarily due to lower sales activity.

Selling, general, and administrative ("SG&A") expenses decreased 30.0% to $2.8 million for the three months ended September 30, 2023 compared $4.1 million during the same period in 2022. This decrease in SG&A expenses was primarily attributable to (i) a decrease of $0.6 million in severance expenses related to the retirement agreement between NGS and Stephen C. Taylor, our prior permanent Chief Executive Officer and current interim Chief Executive Officer, and (ii) $0.4 million decrease in stock compensation expenses. Mr. Taylor continues to be employed as our interim CEO while we search for his permanent replacement.

 

Depreciation and amortization expense increased to $6.8 million for the three months ended September 30, 2023 compared to $6.0 million for the three months ended September 30, 2022, due to increased capital expenditures.

We recorded an income tax expense of approximately $1.0 million for the three months ended September 30, 2023 compared to an income tax benefit of $0.1 million for the three months ended September 30, 2022. For interim periods, our income tax expense is computed based upon our estimated annual effective tax rate and any discrete items that impact the interim periods. Our estimated annual effective tax rate differs from the U.S. federal statutory rate of 21% primarily as a result of expenses not deductible for income tax purposes.

The table below shows our revenues and percentage of total revenues of each of our product lines for the nine months ended September 30, 2023 and 2022.

Total revenue increased 36.3% to $84.9 million for the nine months ended September 30, 2023 compared to $62.3 million during the nine months ended September 30, 2022. This increase was primarily a result of higher rental revenue (38.3% increase) and higher aftermarket service revenue during the first nine months of 2023 (290.9% increase).

Rental revenue increased to $74.5 million for the nine months ended September 30, 2023 compared to $53.9 million during the nine months ended September 30, 2022.  This increase during the first nine months of 2023 was attributable to an increase in high horsepower compression rentals as these units carry a higher rental revenue rate than our lower horsepower units and, to a lesser extent, rental rate increases across a portion of our fleet intended to offset inflationary pressures related to the costs of our rental fleet.

Sales revenue decreased to $6.0 million for the nine months ended September 30, 2023 compared to $7.3 million for the same period in 2022. This decrease is mostly attributable to a decrease in compressor sales. Sales are subject to fluctuations in timing of industry activity related to capital projects and, as such, can vary substantially between periods.

Aftermarket service revenue increased 290.9% to $4.4 million for the nine months ended September 30, 2023 compared to $1.1 million for the nine months ended September 30, 2022. This increase is primarily attributable to freight and commissioning of high horsepower units during the nine months ended September 30, 2023.

Cost of rentals increased 28.1% to $36.5 million during the nine months ended September 30, 2023 compared to $28.5 million during the nine months ended September 30, 2022. This increase was primarily due to inflationary pressures on labor and parts as well as increased high horsepower units being placed into service. While repair and maintenance expenses are customary in our business, the timing of such expenses can fluctuate between periods resulting in periods with larger than normal expenses.

Cost of sales increased 20.1% to $6.6 million during the nine months ended September 30, 2023 compared to $5.5 million during the nine months ended September 30, 2022. This increase during the first nine months of 2023 was primarily due to a increased fabrication costs attributable to our fabrication shops.

Selling, general, and administrative expenses increased 38.2% to $12.3 million for the nine months ended September 30, 2023 compared to $8.9 million for the same period in 2022. SG&A expenses during the first nine months of 2023 were impacted by (i) $1.2 million of severance expenses related to the retirement agreement between NGS and Mr. Stephen Taylor, our prior Chief Executive Officer, (ii) a $0.5 million increase in stock compensation expense when compared to the first 9 months of 2022 and (iii) $0.4 million one time increase in legals costs associated with our cooperation agreement.

 

Depreciation and amortization expense increased 7.0% to $19.4 million for the nine months ended September 30, 2023 compared to $18.1 million for the nine months ended September 30, 2022.  This increase was the result of units in service during 2023.

We recorded an income tax expense of $1.4 million for the nine months ended September 30, 2023 and $0.3 million for the nine months ended September 30, 2022. For interim periods, our income tax (expense) benefit is computed based upon our estimated annual effective tax rate and any discrete items that impact the interim periods.

We recorded an impairment expense of $0.8 million related to capitalized software costs for the nine months ended September 30, 2023.

“Adjusted EBITDA” is a non-GAAP financial measure that we define as earnings (net (loss) income) before interest, taxes, depreciation and amortization, as well as non-cash stock compensation, severance expenses, impairment expenses, an increase in inventory allowance and inventory write-offs, and retirement of rental equipment. This term, as used and defined by us, may not be comparable to similarly titled measures employed by other companies and is not a measure of performance calculated in accordance with GAAP. Adjusted EBITDA should not be considered in isolation or as a substitute for operating income, net income or loss, cash flows provided by operating, investing and financing activities, or other income or cash flow statement data prepared in accordance with GAAP. However, management believes Adjusted EBITDA is useful to an investor in evaluating our operating performance because:

•it is widely used by investors in the energy industry to measure a company’s operating performance without regard to items excluded from the calculation of Adjusted EBITDA, which can vary substantially from company to company depending upon accounting methods and book value of assets, capital structure and the method by which assets were acquired, among other factors;

•it helps investors to more meaningfully evaluate and compare the results of our operations from period to period by removing the impact of our capital structure and asset base from our operating structure; and

•it is used by our management for various purposes, including as a measure of operating performance, in presentations to our Board of Directors, and as a basis for strategic planning and forecasting.

Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our results as reported under generally accepted accounting principles. Some of these limitations are:

•Adjusted EBITDA does not reflect our cash expenditures, future requirements for capital expenditures, or contractual commitments;

•Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;

•Adjusted EBITDA does not reflect the cash requirements necessary to service interest or principal payments on our debts; and

•although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect any capital expenditures for such replacements.

There are other material limitations to using Adjusted EBITDA as a measure of performance, including the inability to analyze the impact of certain recurring items that materially affect our net income or loss, and the lack of comparability of results of operations of different companies. Please read the table below under “Reconciliation” to see how Adjusted EBITDA reconciles to our net (loss) income, for the three months ended and the nine months ended September 30, 2023 and 2022, the most directly comparable GAAP financial measure.

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

For the three months ended September 30, 2023, Adjusted EBITDA increased $4.1 million 53.1% due primarily to a $9.3 million increase in total revenues partially offset by a $3.5 million increase in costs of rentals. For the nine months ended September 30, 2023, Adjusted EBITDA increased $8.1 million (37.7%) due primarily to an $20.6 million increase in rental revenue partially offset by an increase of $8.0 million for cost of rentals.

Our working capital positions as of September 30, 2023 and December 31, 2022 are set forth below:

For the nine months ended September 30, 2023, we invested $128.6 million in rental and property and other equipment by adding $126.4 million in new equipment to our rental fleet and $2.2 million primarily in vehicles as well as various other machinery and equipment. Our investment in rental equipment, property and other equipment also includes any changes to work-in-process related to our rental fleet jobs at the beginning of the period compared to the end of the period. Our rental work-in-process increased by $17.9 million during the nine months ended September 30, 2023. We financed our investment in rental equipment, property and other equipment with cash flow from operations, and borrowings under our Amended and Restated Credit Facility.

We anticipate that our cash flows from operations as well as our borrowing capacity under our Amended and Restated Credit Agreement will provide adequate liquidity for our planned capital expenditures during the remainder of 2023. For any new capital expenditures in 2023 and beyond that exceeds our cash flow from operations and our borrowing base under our Amended and Restated Credit Agreement, we anticipate that we would need to negotiate an expansion of our borrowing capacity under our Amended and Restated Credit Agreement or raise money in the capital markets through sales of equity or debt securities. While we control the timing and extent of our capital expenditures, there is no assurance that any such borrowing expansion would be granted. At September 30, 2023 we had approximately $47 million available for borrowing under the Amended and Restated Credit Agreement, subject to borrowing base determination.

At September 30, 2023, we had cash and cash equivalents of $0.2 million compared to $3.4 million at December 31, 2022. Our cash flows from operating activities of $25.7 million were offset by capital expenditures of $128.6 million during the nine months ended September 30, 2023. We had working capital of $22.1 million at September 30, 2023 compared to $23.7 million at December 31, 2022. We generated cash flows from operating activities of $25.7 million during the first nine months of 2023 compared to cash flows provided by operating activities of $20.2 million for the first nine months of 2022. 

For the remainder of 2023, our overall plan is to continue monitoring and holding expenses in line with the anticipated level of activity, fabricate rental fleet equipment either in-house or through third-party contractors only in direct response to market requirements, emphasize marketing of our idle gas compressor units and utilize bank borrowing in line with market conditions. For the remainder of 2023, our forecasted capital expenditures are not anticipated to exceed our internally generated cash flows, cash on hand and borrowing availability under our Amended and Restated Credit Agreement. The majority of required capital will be for contracted, premium-priced additions to our compressor rental fleet and/or required service vehicles. We believe market conditions indicate significant demand growth for large horsepower compression in 2023 and beyond. While we believe that cash flows from operations, our current cash position and borrowing capacity under our Amended and Restated Credit Agreement will be sufficient to satisfy a portion of our capital activity, we may need to negotiate an expansion of our borrowing capacity under our Amended and Restated Credit Agreement to meet the capital expenditure requirements of any additional demand.

Our condensed consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States. In the ordinary course of business, we have made a number of estimates and assumptions relating to the reporting of results of operations and financial condition in the preparation of our financial statements in conformity with accounting principles generally accepted in the United States. Actual results could differ significantly from those estimates under different assumptions and conditions. Management has determined that our critical accounting policies are those that relate to revenue recognition, estimating the allowance for doubtful accounts, accounting for income taxes, accounting for long-lived assets and accounting for inventory.

There have been no changes in the critical accounting policies disclosed in the Company's Form 10-K for the year ended December 31, 2022.

Please read Note 2, Summary of Significant Accounting Policies, Recently Issued Accounting Pronouncements in our condensed consolidated financial statements in this report.

From time-to-time, we enter into off-balance sheet arrangements and transactions that can give rise to off-balance sheet obligations.  As of September 30, 2023, the off-balance sheet arrangements and transactions that we have entered into include purchase agreements. We do not believe that these arrangements are reasonably likely to materially affect our liquidity or availability of capital resources.

Except for historical information contained herein, the statements in this report are forward-looking and made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements involve known and unknown risks and uncertainties, which may cause our actual results in future periods to differ materially from forecasted results. Those risks include, among other things, the loss of market share through competition or otherwise; the introduction of competing technologies by other companies; a prolonged, substantial reduction in oil and natural gas prices, which could cause a decline in the demand for our products and services; and new governmental safety, health and environmental regulations, which could require us to make significant capital expenditures. The forward-looking statements included in this Form 10-Q are only made as of the date of this report, and we undertake no obligation to publicly update such forward-looking statements to reflect subsequent events or circumstances. A discussion of these and other risk factors is included in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC.

There have been no changes in the market risks disclosed in the Company's Form 10-K for the year ended December 31, 2022.

    Our management, including the Interim Chief Executive Officer and our Interim Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting (“ICFR”), as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements for external purposes in accordance with GAAP.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting as of September 30, 2023, based on the Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Based on the results of this evaluation, the Company’s management concluded that internal control over financial reporting was not effective as of September 30, 2023, due to the material weakness listed below.

A material weakness is a deficiency, or a combination of deficiencies, in ICFR, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

Management identified a material weakness in its internal control over financial reporting at December 31, 2022, over our inventory process which still exists as of September 30, 2023. Specifically, we have identified issues related to: (i) the classification of inventory work in progress; (ii) year-end physical inventory count procedures, and (iii) the process to review and approve inventory adjusting journal entries.

After giving full consideration to this material weakness, and the additional analyses and other procedures that we performed to ensure that our condensed consolidated financial statements included herein were prepared in accordance with U.S. generally accepted accounting principles (“US GAAP”), our management has concluded that our condensed consolidated financial statements present fairly, in all material respects our financial position, results of operations and cash flows for the periods disclosed in conformity with US GAAP.

In response to the material weakness, management, with oversight of the Audit Committee of the Board of Directors, has begun the process of, and is committed to, designing and implementing effective measures to strengthen our internal controls over financial reporting and remediate the material weakness.

Our planned internal control remediation efforts, which are underway, include:

•We have updated and implemented new accounting policies and procedures related to work in process inventory. These included modifying our financial reporting account consolidation procedures and financial review process.

•We have hired additional management with a focus on inventory control and inventory best practices.

•We are taking steps to limit the amount of inventory held outside of centralized warehouses.

•We have improved and enforced our formalized inventory count and inventory adjustment processes which includes taking steps to reinforce the inventory taking procedures, proper training and supervision of warehouse staff.

•We have added additional inventory safeguards in our warehouses limiting physical access to our inventory.

•We have limited the number of employees who can make inventory adjustments in our accounting software by adding additional IT controls around inventory transfers.

•We have engaged a third-party consultant to conduct a full assessment of our controls and procedures.

•We intend to continue efforts to ensure our employees understand the ongoing importance of internal controls and compliance with corporate policies and procedures.

•We have added a highly qualified new member to our board of directors and expanded our audit committee

While these actions and planned actions are subject to ongoing management evaluation and will require validation and testing of the design and operating effectiveness of internal controls over a sustained period of financial reporting cycles, we are committed to the continuous improvement of our internal control over financial reporting and will continue to diligently review our internal control over financial reporting.

 

From time to time, we are a party to various legal proceedings in the ordinary course of our business. While management is unable to predict the ultimate outcome of these actions, it believes that any ultimate liability arising from these actions will not have a material adverse effect on our financial position, results of operations or cash flows. We are not currently a party to any material legal proceedings.

Please refer to and read Item 1A, Risk Factors in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 for a discussion of the risks associated with our Company and industry.
