Principles of Consolidation and Basis of Presentation

The accompanying Consolidated Financial Statements were prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and include the accounts of the Company, its subsidiary, NGSG Properties, LLC, which owns our headquarters office building and the rabbi trust associated with our deferred compensation plan (see Note 12). All significant intercompany accounts and transactions for the periods presented have been eliminated in consolidation.

Certain reclassification have been made to prior periods to conform to the current presentation. In our Consolidated Statements of Operations, (gains) and losses on the sale of property equipment have been reclassified from selling, general and administrative expenses to a stand-alone caption included within total operating income.

Use of Estimates

The preparation of our Consolidated Financial Statements in conformity with GAAP requires our management to make estimates and assumptions that affect the amounts reported in these Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates. Significant estimates include fixed asset lives, provision for credit losses and the allowance for inventory obsolescence. Additionally, we conduct an annual review of our long-lived assets for impairment. In connection with the review, determining factors are based on estimates that can significantly impact the carrying value of these assets. It is at least reasonably possible these estimates could be revised in the near term and the revisions could be material.

Cash and Cash Equivalents

For purposes of reporting cash flows, we consider all short-term investments with an original maturity of three months or less to be cash equivalents. At times, cash balances at banks and financial institutions may exceed federally insured amounts.

Accounts Receivable and Credit Losses

Our trade accounts receivables are not collateralized except as provided for under certain lease agreements.We perform ongoing credit evaluations of our customers and adjust credit limits based on management’s assessment of the customer’s financial condition and payment history, as well as industry and general economic conditions. We continuously monitor collections and payments from our customers, and maintain an allowance for estimated credit losses based upon our historical experience and any specific customer collection issues that we have identified as well as forecasts of future economic conditions. While such credit losses have historically been within our expectations and the allowance established, we cannot guarantee that we will continue to experience the same credit loss rates that we have in the past.

Revenue Recognition

The following is a description of principal activities from which we generate our revenue and the accounting policies that we apply for the recognition thereof:
Rental Revenue. We generate revenue from renting compressor equipment to our customers for the right to control the use of the equipment ratably over the term of the underlying agreement. Our agreements for rental equipment qualify as operating leases under Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 842, Leases (“ASC 842”) as we retain the primary exposure to changes in the underlying equipment’s value as the lessor unlike a sale or secured lending arrangement. Our agreements may also include a fee for servicing the equipment during the term of the rental contract. We have applied the practical expedient provided in ASC 842, which allows us to combine lease and non-lease components. Our rental contracts typically range from six to 60 months.

As a lessor, we recognize operating lease revenue on a straight-line basis with equal monthly payments over the term of the underlying agreements. After the terms of the agreement have expired, a customer may renew their contract or continue renting on a monthly basis thereafter. The leased equipment is generally skid-mounted and can be moved to different locations at the direction of our customers. The leased equipment assets remain on our Consolidated Balance Sheets consistent with other property and equipment. Cash receipts associated with our lease agreements are classified within cash flows from operating activities in our Consolidated Statements of Cash Flows.

Sales and Aftermarket Services Revenue. We generate revenue from the sale of custom/assembled compressors, flare systems and parts, as well as exchange/rebuilding customer owned compressors and sale of used rental equipment. We also provide routine aftermarket or call-out services on customer owned equipment.

Consistent with ASC Topic 606, Revenues from Contracts with Customers (“ASC 606”), revenue is measured and recognized 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). Transaction prices are not subject to variable consideration constraints. Shipping and handling costs incurred are accounted for as fulfillment costs and are included in cost of revenues in our Consolidated Statements of Operations.

For sales, revenue is recognized when control has passed to the customer generally when the equipment is completed and shipped. We request some of our customers to make progressive payments as the product is being built; these payments are recorded as deferred revenue within Accrued liabilities on the 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. The amount of revenue recognized is not adjusted for expected returns, as our historical part returns have been de minimis. Revenue for aftermarket and other services is recognized after the services in the contract are rendered.

Inventory Valuation

Inventory (current and long-term) is valued at the lower of cost or net realizable value. The cost of inventories is determined by the weighted average method. We regularly review inventory quantities on hand and record a provision for excess and obsolete inventory based primarily on current and anticipated customer demand and production requirements. We routinely review our inventory allowance balance to account for slow moving or obsolete inventory costs that may not be recoverable in the future. We assess anticipated customer demand based on current and upcoming capital expenditure budgets of our major customers as well as other significant companies in the industry, along with oil and gas price forecasts and other factors affecting the industry. Our long-term inventory consisted of raw materials and replacement parts that remain useable but that we do not expect to sell or use within the next year.

Long-Lived Assets

Rental equipment and property and equipment are recorded at cost less accumulated depreciation, except for work-in-progress on new rental equipment which is recorded at cost until it’s complete and added to our fleet. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Our rental equipment has estimated useful lives between 15 and 25 years, while our property and equipment has estimated useful lives which range from 3 to 39 years. The majority of our property and equipment, including rental equipment, is a direct cost to generating revenue.

We assess our rental equipment and property and equipment for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The following factors could trigger an impairment review: significant underperformance relative to historical or projected future cash flows; significant adverse changes in the
extent or manner in which the asset (or asset group) is being used or its condition, including a meaningful drop in fleet utilization over the prior four quarters; significant negative industry or company-specific trends or actions, including meaningful capital expenditure budget reductions by our major customers or other sizable exploration and production or midstream companies, as well as significant declines in oil and gas prices; legislative changes prohibiting us from leasing our compressor units; or poor general economic conditions. An impairment loss is recognized if the future undiscounted cash flows associated with the asset (or asset group) and the estimated fair value of the asset are less than the asset’s carrying value.

Sales of equipment out of the rental fleet are included with sales revenue and cost of sales, while retirements of units are presented as a separate operating expense. Maintenance and repairs are charged to cost of rentals as incurred.

Intangible Assets

We amortize intangible assets with definite lives over their useful lives and review for impairment when indicators of impairment are present. We review indefinite-lived intangible assets for impairment annually or when indicators of impairment are present. We review intangibles through an assessment of the estimated future cash flows related to such assets. In the event that assets are found to be carried at amounts in excess of estimated undiscounted future cash flows, then the assets will be adjusted for impairment to a level commensurate with a discounted cash flow analysis of the underlying assets. As of December 31, 2024, we no longer have any intangible assets (see Note 8).

Leases

We determine if an arrangement is a lease at inception by assessing whether it conveys the right to control the use of an identified asset for a period of time in exchange for consideration. GAAP requires all leases to be reported on the balance sheet as right-of-use (“ROU”) assets and lease obligations. We determine if an arrangement is a lease at inception and determine lease classification and recognize ROU assets and liabilities on the lease commencement date based on the present value of lease payments over the lease term. As the discount rate implicit in the lease is rarely readily determinable, we estimate our incremental borrowing rate using information available at the commencement date in determining the present value of the lease payments. We, as a lessee, apply the practical expedient to not separate non-lease components from lease components, therefore, accounting for each separate lease component and its associated non-lease component, as a single lease component. For each lease that (i) contains the same timing and pattern of transfer for lease and non-lease components and (ii) if the lease component, if accounted for separately, would be classified as an operating lease, we have elected to not separate non-lease components from lease components. Right of use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As substantially all of our leases do not provide an implicit rate, we use our incremental borrowing rate, which is based on a fully collateralized loan over the lease term, to determine the present value of lease payments.

Income Taxes

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 net operating losses and tax credit carry-forwards. 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. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the statutory enactment date. 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.

With respect to uncertain tax positions, GAAP prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. In order to record any financial statement benefit, we are required to determine, based on technical merits of the position, whether it is more likely than not (a likelihood of more than 50 percent) that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes. If that step is satisfied, then we must measure the tax position to determine the amount of benefit to recognize in the financial statements. The tax position is measured at the largest amount of the benefit that is greater than 50 percent likely of being realized upon ultimate settlement. We had no liabilities for uncertain tax positions as of December 31, 2024 and 2023.

Our policy regarding income tax interest and penalties is to charge those items as components of interest expense and other expense, respectively.
Capitalized Interest

We capitalize interest from external borrowings on significant expenditures for the assembly of our 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.

Fair Value Measurement

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. GAAP provides for a fair value hierarchy, which requires an entity to maximize the use of observable inputs when measuring fair value. These inputs are categorized as follows:

Level 1 - quoted prices in an active market for identical assets or liabilities;

Level 2 - quoted prices in an active market for similar assets or liabilities, inputs other than quoted prices that are observable for similar assets or liabilities, inputs derived principally from or corroborated by observable market data by correlation or other means; and

Level 3 - valuation methodology with unobservable inputs that are significant to the fair value measurement.
    
We believe that the fair value of our cash and cash equivalents, trade accounts receivables, and accounts payable as of December 31, 2024 and 2023 approximate their carrying values due to the short-term nature of the instruments or the use of prevailing market interest rates. We considered the borrowings under our credit facility to approximate fair value based upon variable interest rates currently available to us for loans with similar terms (level 2).

Segments and Related Information

GAAP defines the characteristics of an operating segment as (i) being engaged in business activity from which it may earn revenue and incur expenses, (ii) being reviewed by the Company’s chief operating decision maker (“CODM”) for decisions about resources to be allocated and assess its performance and (iii) having discrete financial information. Although we review our products to analyze the nature of our revenue, costs and expenses, the net income and non-GAAP financial measures including EBITDA and Adjusted gross margin are not captured or analyzed by these categories. Our chief executive officer (“CEO”) serves as the CODM and does not make resource allocation decisions or assess the performance of the business based on these categories, but rather on the entire entity in the aggregate. Accordingly, the measures of profit and loss and total assets are effectively those of the Company as a whole as reflected in these Consolidated Financial Statements. Based on these facts and underlying circumstances described further below, we have concluded that we operate in one business segment.

We are primarily engaged in the business of leasing natural gas compressors to our customers. In addition, we design, assemble and sell natural gas compressors and provide aftermarket services on compressors in our fleet and to third parties. These business activities are similar in all geographic areas in which we operate. Our customers primarily consist of entities in the business of producing oil and gas. The maintenance and service of our products is consistent across the entire Company and is performed by a dedicated group of employees via an internal fleet of vehicles. The regulatory environment is similar in every jurisdiction in that the most impacting regulations and practices are the result of federal energy policy. 

Recently Adopted Accounting Pronouncements

In December 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-09 “Income Taxes (Topics 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”) to expand the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. We elected to early adopt ASU 2023-09 effective with our financial reporting for the year ended December 31, 2024 and have applied the provisions on a retrospective basis for all periods presented in these Consolidated Financial Statements. Accordingly, the enhanced disclosures required of ASU 2023-09 are provided in Note 11.

In November 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”) which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. We adopted ASU 2023-07 effective January 1, 2024 and the required disclosures are referenced above in our discussion of Segments and Related Information.
Recently Issued Accounting Pronouncements Pending Adoption

In November 2024, the FASB issued ASU 2024-03 “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expense” (“ASU 2024-03”) which expands annual and interim disclosures expenses for certain types of expenses (including purchases of inventory, employee compensation, depreciation, amortization, and depletion) in commonly presented expense captions (such as cost of sales, selling, general & administrative expenses, and research and development). ASU 2024-03 is effective for annual periods beginning January 1, 2027, and for interim periods beginning January 1, 2028, with early adoption permitted. The adoption of ASU 2024-03 is not expected to have a material impact on our Consolidated Financial Statements or disclosures.
