Notes to Condensed Consolidated Financial Statements

(unaudited)

(1) Basis of Presentation and Summary of Significant Accounting Policies

These notes apply to the unaudited condensed consolidated financial statements of Natural Gas Services Group, Inc. a Colorado corporation (the "Company", “NGSG”, "Natural Gas Services Group", "we" or "our"). 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 (see Note 5). 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, 2019 and the results of our operations for the three and nine months ended September 30, 2019 and 2018 not misleading. As permitted by the rules and regulations of the Securities and Exchange Commission (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 financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2018 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, 2019 are not necessarily indicative of the results of operations to be expected for the full fiscal year ending December 31, 2019.

Revenue Recognition Policy

The Company adopted ASC 606, Revenue from Contracts with Customers ("ASC 606") on January 1, 2018. As a result, the Company has changed its accounting policy for revenue recognition as detailed below.

The Company applied ASC 606 using the cumulative effect method. We had no significant changes in our recognition of revenue at adoption and our review of all open revenue from contracts with customers on January 1, 2018 indicated we had no adjustment to be made. If an adjustment had been needed, we would have recognized the cumulative effect of initially applying ASC 606 with an adjustment to the opening balance of equity at January 1, 2018.

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). We recognize revenue once our performance obligation has been satisfied and control over a product or service has transferred to the customer. Shipping and handling costs incurred are accounted for as fulfillment costs and are included in cost of revenues in our condensed consolidated income statement.

Nature of Goods and Services

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

Rental Revenue. The Company generates revenue from renting compressors and flare systems to our customers. These contracts may also include a fee for servicing the compressor or flare during the rental contract. Our rental contracts generally range from six to 60 months, with our larger horsepower compressors having longer minimum contract terms. Our rental revenue is recognized over time, with equal monthly payments over the term of the contract. After the term of a contract has expired, a customer may renew their contract or continue renting on a monthly basis thereafter. In accordance ASC 842 – Leases, 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, flare systems, and parts, as well as, exchange/rebuilding customer owned compressors and sale of used rental equipment.

Custom/fabricated compressors and flare systems - The Company designs and fabricates compressors and flares 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 or flare package is complete and shipped, or in accordance with a bill and hold arrangements 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, upon the customer’s written request, 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 at a later specified date and that we segregate the equipment from our finished goods, such that they are 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 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 shouldered by the customer and there are no exceptions to the customer’s commitment to accept and pay for the manufactured equipment. Revenues recognized related to bill and hold arrangements for the nine months ended September 30, 2019 was approximately $ 9.4 million.

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 by physical delivery, delivery and installment or shipment of the compressor.

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

Service and Maintenance Revenue . The Company provides routine or call-out services on customer owned equipment. Revenue is recognized after services in the contract are rendered.

Payment terms for sales revenue and service and maintenance revenue 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.

Disaggregation of Revenue

The following table shows the Company's revenue disaggregated by product or service type for the three and nine months ended September 30, 2019 and 2018:

Contract Balances

As of September 30, 2019 and December 31, 2018, we had the following receivables and deferred income from contracts with customers:


	September 30, 2019		December 31, 2018
	(in thousands)
Accounts Receivable
Accounts receivable - contracts with customers	$	4,038	$	2,250
Accounts receivable - non-ASC 606	7,511		5,260
Total Accounts Receivable	$	11,549	$	7,510
Less: Allowance for doubtful accounts	( 325 )		( 291 )
Total Accounts Receivable, net	$	11,224	$	7,219

Deferred income	$	81	$	81

The Company recognized $ 47,000 in revenue for the nine months ended September 30, 2019 that was included in deferred income at the beginning of 2019. For the year ended December 31, 2018, the Company recognized revenue of $ 176,000 from amounts related to sales that were included in deferred income at the beginning of 2018.

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

Transaction Price Allocated to the Remaining Performance Obligations

As of September 30, 2019, the Company did not have revenue related to performance obligations under ASC 606-10-50-13.

Contract Costs

The Company applies the practical expedient in ASC 340-40-25-4 and 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 expense on our consolidated income statement.

Leases

On January 1, 2019, we adopted ASC 842, Leases ("ASC 842") and all the related amendments using the modified retrospective method. We recognized the cumulative effect of initially applying the new lease standard and had no adjustments to retained earnings. The comparative information has not been restated and continues to be reported under the lease accounting standard in effect for those periods. We do not expect the adoption of the new lease standard to have a material impact to our net income on an ongoing basis.

The new lease standard requires all leases to be reported on the balance sheet as right-of-use assets and lease obligations. We elected the practical expedients permitted under the transition guidance of the new standard that retained the lease classification and initial direct costs for any leases that existed prior to adoption of the standard. We did not reassess whether any contracts or land easements entered into prior to adoption are leases or contain leases.

The cumulative effect of the changes made to our consolidated balance sheet at January 1, 2019, for the adoption of ASU 2016-02, Leases, was as follows (in thousands):


	Balance at December 31, 2018		Adjustments due to ASU 2016-02		Balance at January 1, 2019
Balance Sheet
Assets
Right of use assets	$	—	$	451	$	451
Liabilities
Current portion of operating leases	$	—	$	126	$	126
Long term portion of operating leases	—		325		325
Total lease liabilities	$	—	$	451	$	451

The Company, as a lessee, applies the practical expedient in ASC 842-10-15-37, and does 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.

The Company, as a lessor, applies the practical expedient in ASC 842-10-15-42A, in leases that contain the same timing and pattern of transfer for lease and non-lease components and are deemed operating leases, the lessor is not required to separate non-lease components from lease components. Therefore, on any lease that meets these qualifications we have chosen to account for each separate lease component and its associated non-lease component, as a single lease component.

The Company applies the practical expedient in ASC 842-20-25-2, to recognize the lease payments in profit or loss on a straight-line basis over the lease term and variable lease payments in the period in which the obligation for those payments is incurred for leases with terms of 12 months or less.

Fair Value of Financial Instruments

Our financial instruments consist principally of cash and cash equivalents, accounts receivable, accounts payable, deferred compensation plan (cash portion) and our line of credit. Pursuant to ASC 820 (Accounting Standards Codification), the fair value of our cash equivalents is determined based on “Level 1” inputs, which consist of quoted prices in active markets for identical assets. We believe that the recorded values of all of our other financial instruments approximate their fair values because of their nature (variable rate debt) and relatively short maturity dates or durations.

Income Taxes

As part of the process of preparing our financial statements, we are required to estimate our federal income taxes as well as income taxes in each of the states in which we operate. We use an estimated annual effective tax rate for purposes of determining the income tax provision during interim reporting periods. In calculating our estimated annual effective tax rate, we consider forecasted annual pre-tax income and estimated permanent book versus tax differences, as well as tax credits. Adjustments to the effective tax rate and estimate will occur as information and assumptions change.This process involves us estimating our actual current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheet. We must then assess the likelihood that our deferred tax assets will be recovered from future taxable income and, to the extent we believe that recovery is not probable, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance in a period, we must include an expense in the tax provision in the statement of operations.

Significant management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. We currently have no valuation allowance and fully expect to utilize all of our deferred tax assets.

ASC Topic 740 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 has a greater than 50 percent likelihood of being realized upon ultimate settlement.

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

During the fourth quarter of 2018, the Company discovered a potential uncertain tax position attributable to the deductibility of certain executive compensation expense for federal income tax purposes aggregating approximately $ 168,000 , $ 149,000 and $ 230,000 for the years ended December 31, 2017, 2016 and 2015, respectively. As a result, in accordance with ASC Topic 740, during the fourth quarter of 2018, the Company recorded a tax adjustment of $ 547,000 and accrued penalty and interest expense of $ 55,000 attributable to the uncertain tax position. The Company's management determined the effect of the potential uncertain tax position on previously reported results of operations for the years ended December 31, 2017 and 2016 was not material.

As of September 30, 2019, the Company has filed an amended tax return for the year ended 2015 and has recognized certain offsetting deductions thus reducing our uncertain tax position reserve for 2015, 2016 and 2017. Accrued interest and penalties at September 30, 2019 related to 2016 and 2017 uncertain tax position was approximately $ 23,000 . The Company plans on amending it's 2016 and 2017 filed federal income tax returns and is still in the process of analyzing certain offsetting deductions to reduce the uncertain tax position reserve.

We account for uncertain tax positions in accordance with guidance in FASB 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 financial statements. A reconciliation of uncertain tax positions of the beginning and ending amount of uncertain tax positions is as follows (in thousands):


Balance at January 1, 2019	$	578
Additions based on tax positions related to current year	—
Reductions for tax positions of prior years	( 319 )
Balance at September 30, 2019	$	259

Reclassification of Prior Period Balances

Certain reclassifications have been made to prior period amounts, due to our adoption of ASC 842, to conform to the current-year presentation. These reclassifications had no effect on the financial statements.

The summary of the status of our unvested stock options as of December 31, 2018 and changes during the nine months ended September 30, 2019 is presented below.


Unvested stock options:	Shares	Weighted Average Grant Date Fair Value Per Share
Unvested at December 31, 2018	20,865	$	11.93

Vested	( 10,432 )	11.93

Unvested at September 30, 2019	10,433	$	11.93

As of September 30, 2019, there was $ 46,105 of unrecognized compensation cost related to unvested options. Such cost is expected to be recognized over a weighted-average period of one year . Total compensation expense for stock options was $ 91,984 and $ 127,055 for the nine months ended September 30, 2019 and 2018, respectively.

Restricted Shares/Units:

In accordance with the Company's employment agreement with Stephen Taylor, the Company's Chief Executive Officer, the Compensation Committee reviewed his performance in determining the issuance of restricted common stock. Based on this review which included consideration of the Company's 2018 performance, Mr. Taylor, was awarded 131,674 restricted shares/units on March 29, 2019, which vest over three years , in equal annual installments, beginning March 29, 2020. On March 29, 2019, the Compensation Committee awarded 20,000 restricted shares/units to each of G. Larry Lawrence, our CFO, and James Hazlett, our Vice President of Technical Services. The restricted shares to Messrs. Lawrence and Hazlett vest over three years , in equal annual installments, beginning March 29, 2020. We also awarded and issued 23,136 shares of restricted common stock to the independent members of our Board of Directors as partial payment for 2019 services as directors. The restricted stock issued to our directors vests over one year , in quarterly installments, beginning March 31, 2020. Total compensation expense related to restricted awards was $ 1.7 million and $ 1.6 million for the nine months ended September 30, 2019 and 2018, respectively. As of September 30, 2019, there was a total of $ 4.3 million of unrecognized compensation expense related to these shares/units which is expected to be recognized over the next three years .

(3) Inventory

Our inventory, net of allowance for obsolescence of $ 3.4 million at September 30, 2019 and $ 19,000 December 31, 2018 consisted of the following amounts:


	September 30, 2019		December 31, 2018
	(in thousands)
Raw materials - current	$	23,893	$	26,152
Raw materials - long term, net	540		3,980
Finished Goods	1,022		1,022
Work in process	5,374		3,800
	$	30,829	$	34,954

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

(4) Inventory Allowance and Retirement of Long-Lived Assets

Given its concerns about the current industry and broader economic backdrop, Company management conducted a detailed review of our rental compressor units and initiated a thorough inventory analysis during the third quarter of 2019. Due to the slow moving nature or obsolescence of long-term inventory and inventory related to the retirement of rental equipment, management recorded an increase of $ 3.4 million in the inventory allowance reserve for costs that may not be recoverable in the future.

During the review of our rental compressor units, management looked for any units that were not of the type, configuration, make or model that our customers are demanding or that were not cost efficient to refurbish, maintain and/or operate. As a result of this review, we determined 327 units should be retired from our rental fleet. We performed an optimization review and recorded a $ 1.5 million loss on retirement of rental equipment to reduce the book value of each unit to zero.

(5) Deferred Compensation Plan

The Company has a non-qualified deferred compensation plan for executive officers, directors and certain eligible employees. The assets of the deferred compensation plan are held in a rabbi trust and are subject to additional risk of loss in the event of bankruptcy or insolvency of the Company. The plan allows for deferral of up to 90 % of a participant’s base salary, bonus, commissions, director fees and restricted stock unit awards. A Company owned life insurance policy held in a rabbi trust is utilized as a source of funding for the plan. The cash surrender value of the life insurance policy is $ 1.4 million and $ 1.1 million as of September 30, 2019 and 2018, respectively. For the nine months ending September 30, 2019, we reported in other income (expense) in the consolidated income statement a gain related to the policy of approximately $ 145,000 and for the same period in 2018, a loss of approximately $ 15,000 .

For deferrals of base salary, bonus, commissions and director fees, settlement payments are made to participants in cash, either in a lump sum or in periodic installments. The obligation to pay the deferred compensation and the deferred director fees is adjusted to reflect the positive or negative performance of investment measurement options selected by each participant and was $ 1.5 million and $ 1.2 million as of September 30, 2019 and 2018, respectively. The deferred obligation is included in other long-term liabilities in the condensed consolidated balance sheet.

For deferrals of restricted stock units, the plan does not allow for diversification, therefore, distributions are paid in shares of common stock and the obligation is carried at grant value. As of September 30, 2019 and 2018, respectively, we have 94,148 and 102,793 unvested restricted stock units being deferred. As of September 30, 2019 and 2018, respectively we have released and issued 80,604 and 33,834 shares to the deferred compensation plan with a value of $ 1.7 million and $ 857,000 , respectively.

(6) Goodwill

Goodwill is tested annually for impairment or as needed upon the occurrence of certain events or substantive changes in circumstances that indicate goodwill is more likely than not impaired. In the last several months, the Company experienced a significant decline in stock price, which is reflective of the significant deterioration of stock prices of companies throughout the oilfield services sector. Accordingly, we calculated our market capitalization (based on our closing stock price) as of September 30, 2019, and compared it to the carrying value of our net assets. Since the carrying value of our net assets exceeded our market capitalization and after considering various economic, industry, and company-specific factors, Company management determined that it was more likely than not that the fair value of the Company’s net assets was less than its carrying amount.

As a result of our qualitative assessment, we proceeded to perform our quantitative goodwill impairment analysis, where we used an independent valuation specialist to assist us in determining the fair value of our net assets. In this impairment analysis, the estimated fair value of our net assets was determined utilizing market and income-based approaches. Determining fair value in this analysis required significant judgment, including judgments about appropriate comparable companies, appropriate discount rates and our estimated future cash flows, which are subject to change. As a result of our quantitative evaluation, we recorded a goodwill impairment charge of $ 10.0 million during the third quarter of 2019.

A summary of changes in the Company’s goodwill during the nine months ended September 30, 2019 is as follows (in millions):


	Goodwill, net
December 31, 2018	$	10,039
Impairments	( 10,039 )
September 30, 2019	$	—

(7) Credit Facility

We have a senior secured revolving credit agreement the ("Amended Credit Agreement") with JP Morgan Chase Bank, N.A (the "Lender") with an aggregate commitment of $ 30 million, subject to collateral availability. We also have a right to request from the Lender, on an uncommitted basis, an increase of up to $ 20 million on the aggregate commitment (which could potentially increase the commitment amount to $ 50 million). On August 31, 2017, we amended and renewed the Amended Credit Agreement, extending the maturity date to December 31, 2020. No other material revisions were made to the credit facility.

Borrowing Base . At any time before the maturity of the Amended 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) 80 % of our eligible accounts receivable plus (b) 50 % of the book value of our eligible general inventory (not to exceed 50 % of the commitment amount at the time) plus (c) 75 % of the book value of our eligible equipment inventory. The Lender may adjust the borrowing base components if material deviations in the collateral are discovered in future audits of the collateral. We had $ 29.5 million borrowing base availability at September 30, 2019 under the terms of our Amended Credit Agreement.

Interest and Fees . Under the terms of the Amended Credit Agreement, we have the option of selecting the applicable variable rate for each revolving loan, or portion thereof, of either (a) LIBOR multiplied by the Statutory Reserve Rate (as defined in the Amended Credit Agreement), with respect to this rate, for Eurocurrency funding, plus the Applicable Margin (“LIBOR-based”), or (b) CB Floating Rate, which is the Lender's Prime Rate less the Applicable Margin; provided, however, that no more than three LIBOR-based borrowings under the agreement may be outstanding at any one time. For purposes of the LIBOR-based interest rate, the Applicable Margin is 1.50 %. For purposes of the CB Floating Rate, the Applicable Margin is 1.50 %. For the nine month period ended September 30, 2019, our weighted average interest rate was 3.38 %.

Accrued interest is payable monthly on outstanding principal amounts, provided that accrued interest on LIBOR-based loans is payable at the end of each interest period, but in no event less frequently than quarterly. In addition, fees and expenses are payable in connection with our requests for letters of credit (generally equal to the Applicable Margin for LIBOR-related borrowings multiplied by the face amount of the requested letter of credit) and administrative and legal costs.

Maturity . The maturity date of the Amended Credit Agreement is December 31, 2020, at which time all amounts borrowed under the agreement will be due and outstanding letters of credit must be cash collateralized. The agreement may be terminated early upon our request or the occurrence of an event of default.

Security . The obligations under the Amended Credit Agreement are secured by a first priority lien on all of our inventory and accounts and leases receivables, along with a first priority lien on a variable number of our leased compressor equipment the book value of which must be maintained at a minimum of 2.00 to 1.00 commitment coverage ratio (such ratio being equal to (i) the amount of the borrowing base as of such date to (ii) the amount of the commitment as of such date).

Covenants. The Amended Credit Agreement contains customary representations and warranties, as well as covenants which, among other things, 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 also have certain financial covenants that require us to maintain on a consolidated basis a leverage ratio less than or equal to 2.50 to 1.00 as of the last day of each fiscal quarter.

Events of Default and Acceleration. The Amended 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 loan 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 $ 50,000 ; certain bankruptcy or insolvency events; the rendering of certain judgments in excess of $ 150,000 ; certain ERISA events; certain change in control events and the defectiveness of any liens under the secured revolving credit facility. Obligations under the Amended Credit Agreement may be accelerated upon the occurrence of an event of default.

As of September 30, 2019, we were in compliance with all covenants in our Amended Credit Agreement. A default under our Credit Agreement could trigger the acceleration of our bank debt so that it is immediately due and payable. Such default would likely limit our ability to access other credit. At September 30, 2019 and December 31, 2018, our outstanding balance on the line of credit was $ 417,000 .

(8) Leases

The Company adopted the new lease standard on January 1, 2019 using the modified retrospective transition method. Prior periods were not retrospectively adjusted and continue to be reported under the accounting standards in effect for those periods. The Company elected the package of practical expedients permitted under the transition guidance within the new lease standard, which among other things, allowed the company to continue to account for existing leases based on the historical lease classification. The Company also elected the practical expedients to exclude right-of-use ("ROU") assets and lease liabilities for leases with an initial term of 12 months or less from the balance sheet, and to combine lease and non-lease components for property leases, which primarily relate to ancillary expenses such as common area maintenance charges and management fees.

The Company determines 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. The Company’s leases are primarily related to property leases for its field offices. The Company's leases have remaining lease terms of one to 10 years. Renewal and termination options are included in the lease term when it is reasonably certain that the Company will exercise the option.

The Company's lease agreements do not contain any contingent rental payments, material residual guarantees or material restrictive covenants.

ROU 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 the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate to determine the present value of lease payments. Based on the present value of lease payments for the Company's existing leases, the Company recorded net lease assets and lease liabilities of approximately $ 451,000 , respectively, upon adoption. The Company had no finance leases. The new lease standard did not materially impact the Company's consolidated statements of operations and had no impact on the Company's consolidated statements of cash flows.

The impact of the new lease standard on the September 30, 2019 consolidated balance sheet was as follows:


	Classification on the Condensed Consolidated Balance Sheet	September 30, 2019
		(in thousands, except years)
Operating lease assets	Right of use assets-operating leases	$	447

Current lease liabilities	Current operating leases	$	107
Noncurrent lease liabilities	Long-term operating leases	340
Total lease liabilities		$	447

Weighted average remaining lease term in years		2.9
Implicit Rate		3.8		%

Operating lease costs are recognized on a straight-line basis over the lease term. Total operating lease costs for the nine months ended September 30, 2019 was approximately $ 426,000 , which included approximately $ 277,000 related to short-term lease costs.

(10) Segment Information

ASC 280-10-50, “Operating Segments", defines the characteristics of an operating segment as: a) being engaged in business activity from which it may earn revenue and incur expenses, b) being reviewed by the Company's chief operating decision maker (CODM) for decisions about resources to be allocated and assess its performance and c) having discrete financial information. Although we look at our products to analyze the nature of our revenue, other financial information, such as certain costs and expenses, net income and EBITDA are not captured or analyzed by these categories. Our CODM does not make resource allocation decisions or access the performance of the business based on these categories, but rather in the aggregate. Based on this, management believes that it operates in one business segment.

In their analysis of product lines as potential operating segments, management also considered ASC 280-10-50-11, “Aggregation Criteria”, which allows for the aggregation of operating segments if the segments have similar economic characteristics and if the segments are similar in each of the following areas:

• The nature of the products and services;

• The nature of the production processes;

• The type or class of customer for their products and services;

• The methods used to distribute their products or provide their services; and

• The nature of the regulatory environment, if applicable.

We are engaged in the business of designing and manufacturing compressors and flares. Our compressors and flares are sold and rented to our customers. In addition, we provide service and maintenance on compressors in our fleet and to third parties. These business activities are similar in all geographic areas. Our manufacturing process is essentially the same for the entire Company and is performed in-house at our facilities in Midland, Texas and Tulsa, Oklahoma. Our customers primarily consist of entities in the business of producing natural gas and crude oil. The maintenance and service of our products is consistent across the entire Company and is performed 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. In addition, the economic characteristics of each customer arrangement are similar in that we maintain policies at the corporate level.

(11) Commitments and Contingencies

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 flow. We are not currently a party to any material legal proceedings, and we are not aware of any threatened material litigation.

As of September 30, 2019, the Company has a remaining contractual obligation related to the construction of a new corporate office of approximately $ 375,000 , to be financed by cash on hand. Construction of a new office began in late 2017 and is expected to be completed in 2019.

Stock Repurchase Program

On August 12, 2019, the Company announced the Board of Directors had authorized the repurchase of up to $ 10.0 million of its outstanding shares of common stock in the open market, block trades or privately negotiated transactions. The timing and extent of any repurchase is subject to the discretion of management and is dependent upon market pricing and conditions, business, legal, accounting and other considerations. The repurchase program does not obligate the Company to purchase any shares and will expire on September 30, 2020, subject to earlier termination of the program by the Board of Directors. The repurchase program may be modified, suspended or terminated at any time without notice, in the Company’s discretion, based upon a number of factors, including market conditions, the cost of repurchasing shares, the availability of alternative investment opportunities, liquidity, the need for capital in the Company’s operations and other factors deemed appropriate. The Company intends to finance the repurchases with existing liquidity and free cash flow. As of September 30, 2019, the Company repurchased 37,936 of its outstanding shares of common stock with a value of $ 490,000 , at an average price of $ 12.91 . As of September 30, 2019, the Company had approximately $ 9.5 million remaining under the repurchase authorization .

(12) Related Party

In 2016, we entered into a joint venture partnership, N-G, LLC (‘N-G”), with Genis Holdings, LLC (“Genis”) to explore new technologies for wellhead compression. NGS and Genis both share 50 % ownership of N-G. In 2018, we ordered some compressor packages from Genis, totaling $ 1.0 million. The compressors were completed and delivered during the first quarter of 2019. As of September 30, 2019, the units were paid in full and reclassified from prepaids and are included in rental equipment on the consolidated balance sheet.

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, 2018 filed with the SEC.

Overview

We fabricate, manufacture, rent, and sell natural gas compressors and related equipment. Our primary focus is on the rental of natural gas compressors. Our rental contracts generally provide for initial terms of six 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 the rented compressors. As of September 30, 2019, we had 1,401 natural gas compressors totaling 270,222 horsepower rented to 93 customers compared to 1,324 natural gas compressors totaling 217,315 horsepower rented to 87 customers at September 30, 2018.

We also fabricate 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 our assembling of these components on skids for delivery to customer locations. The major components of our compressors 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. In the past, we have not experienced any sudden and dramatic increases in the prices of the major components for our compressors. However, the occurrence of such an event could have a material adverse effect on the results of our operations and financial condition, particularly if we were unable to increase our rental rates and sales prices proportionate to any such component price increases.

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. We also design, fabricate, sell, install, and service flare stacks and related ignition and control devices for onshore and offshore incineration of gas compounds such as hydrogen sulfide, carbon dioxide, natural gas and liquefied petroleum gases. To provide customer support for our compressor and flare 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. Formal 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 natural gas and crude oil and the corresponding changes in commodity prices. As demand and prices increase, oil and natural gas producers increase their capital expenditures for drilling, development and production activities. Generally, the increased capital expenditures ultimately result in greater revenues and profits for services 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 rental and sales in the non-conventional 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 non-conventional 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 have increased the market need for larger horsepower compressor packages. We recognized this need over the past two to three 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 1,380 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.

We typically experience a decline in demand during periods of low crude oil and natural gas prices. Low crude oil and natural gas prices experienced throughout 2016 continued into mid-2017. In the latter half of 2017, we saw an increase in oil prices and activity that continued during most of 2018. During 2019, we have witnessed a moderation of crude oil prices as well as drilling and completion activity levels. Activity levels of E&P companies have been and will be dependent not only on commodity prices, but also on their ability to generate sufficient operational cash flow to fund their activities. Generally, though, we feel that production activities (of which we are involved) will fare better than drilling activity. While the continuation of this level of activity is uncertain and variable period to period, we believe the long-term trend in our market is favorable.

Results of Operations

Three months ended September 30, 2019, compared to the three months ended September 30, 2018.

The table below shows our revenues and percentage of total revenues of each of our product lines for the three months ended September 30, 2019 and 2018.


	Revenue Three months ended September 30,
	(in thousands)
	2019						2018
Rental	$	14,434	69	%	$	12,039		73	%
Sales	5,877		28	%	3,947			24	%

Service and Maintenance	541		3	%	410			3	%
Total	$	20,852			$	16,396

Total revenue increased to $20.9 million from $16.4 million, or 27.2%, for the three months ended September 30, 2019, compared to the same period ended September 30, 2018. This increase was mainly a result of higher rental revenue primarily due to a greater number of large horsepower units being rented and an increase in compressor sales compared to the same period in 2018.

Rental revenue increased to $14.4 million from $12.0 million for the three months ended September 30, 2019, compared to the same period ended September 30, 2018. We ended the quarter with 2,277 compressor packages in our fleet, down from 2,567 units at September 30, 2018, due to the retirement of 327 units during the third quarter of 2019. The rental fleet had a unit utilization as of September 30, 2019 and 2018, respectively, of 61.5% and 51.6% while our horsepower utilization for the same periods, respectively, was 66.4% and 55.2%. The rise in both utilizations was mainly the result of the rise in demand for our higher horsepower units as well as unit retirements during the third quarter of 2019.

Sales revenue increased to $5.9 million from $3.9 million for the three months ended September 30, 2019 compared to the same period ended September 30, 2018. This increase was the result of fluctuations in timing of industry activity related to capital projects. We believe this timing is reflective of the typical sales cycle, resulting in fluctuating compressor unit sales to third parties from our Tulsa and Midland operations.

In the last several months, the Company experienced a significant decline in stock price, which is reflective of the significant deterioration of stock prices of companies throughout the oilfield services sector. As a result, the Company performed a goodwill impairment analysis as of September 30, 2019. The analysis showed our carrying value of net assets exceeded its fair value, indicating that goodwill was fully impaired. Accordingly, the Company recorded a goodwill impairment charge of $10.0 million during the third quarter of 2019.

Due to the slow moving nature or obsolescence of long-term inventory and inventory related to the retirement of rental equipment, management started a thorough inventory analysis during the third quarter of 2019. Accordingly, management has recorded an increase of $3.4 million in the inventory allowance reserve for costs that may not be recoverable in the future.

During the third quarter of 2019, management performed a review of our rental compressor units and determined that 327 units should be retired, representing total horsepower of 39,758. Based on this review, at September 30, 2019, we recorded a $1.5 million non-cash loss on the retirement of rental equipment to reduce the book value of these units to zero.

Our operating (loss) income decreased to a loss of $13.6 million compared to a loss of $44,000 for the three months ended September 30, 2019 and September 30, 2018, respectively. This decrease was mainly due to an increased inventory allowance, loss on the retirement of rental units, and a goodwill impairment charge recorded in third quarter of 2019 that totaled $14.9 million, partially offset by higher rental revenues and compressor sales.

Selling, general, and administrative expense increased to $2.8 million from $2.4 million for the three months ended September 30, 2019, and September 30, 2018, respectively. The increase in selling, general and administrative expenses was largely due to an increase in officer incentive bonuses.

Depreciation and amortization expense increased to $5.9 million for the three months ended September 30, 2019, from $5.5 million for the period ended September 30, 2018. This increase was the result of larger horsepower units being added to the fleet. We added 60 units (approximately 56,000 horsepower) to our fleet over the past 12 months. Forty-two of these were 400 horsepower or larger, representing 95% of the horsepower added.

We recorded income tax benefit of $1.2 million for the three months ended September 30, 2019 compared to income tax benefit of $100,000 for the three months ended September 30, 2018. For interim periods, our income tax benefit 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 rates of 21%. The change in tax benefit was primarily a result of a loss before provision for income taxes of $13.5 million during the third quarter of 2019, which was largely due to goodwill impairment, an increased inventory allowance, and retirement of rental equipment that totaled $14.9 million.

Nine months ended September 30, 2019, compared to the nine months ended September 30, 2018.

The table below shows our revenues and percentage of total revenues of each of our product lines for the nine months ended September 30, 2019 and 2018.


	Revenue Nine months ended September 30,

Service and Maintenance	1,529		3	%	1,053		2	%
Total	$	58,738			$	49,318

Total revenue increased to $58.7 million from $49.3 million, or 19.1%, for the nine months ended September 30, 2019, compared to the same period ended September 30, 2018. Comparing the nine months ended September 30, 2019 to the same period in 2018, rental revenue increased 18.5% primarily due to a greater number of large horsepower units being rented. We also saw an increase in sales revenue of 18.7% due to increased compressor sales.

Rental revenue increased to $41.4 million from $34.9 million for the nine months ended September 30, 2019, compared to the same period ended September 30, 2018. We ended the quarter with 2,277 compressor packages in our rental fleet, down from 2,567 units at September 30, 2018 due to the retirement of 327 units during the third quarter of 2019. The rental fleet had a unit utilization as of September 30, 2019 and 2018, respectively, of 61.5% and 51.6%, while our horsepower utilization for the same periods, respectively, was 66.4% and 55.2%. The rise in utilization was mainly the result of the rise in demand for our higher horsepower units as well as unit retirements during the third quarter of 2019.

Sales revenue increased to $15.8 million from $13.3 million for the nine months ended September 30, 2019, compared to the same period ended September 30, 2018. This increase was the result of the fluctuations in timing of industry activity related to capital projects. We believe this timing is reflective of the typical sales cycle, resulting in fluctuating compressor unit sales to third parties from our Tulsa and Midland operations.

Due to the slow moving nature or obsolescence of long-term inventory and inventory related to the retirement of rental equipment, management started a thorough inventory analysis during the third quarter of 2019. Accordingly, management recorded an increase of $3.4 million in the inventory allowance reserve for costs that may not be recoverable in the future.

During the third quarter of 2019 management performed a review of our rental compressor units and determined that 327 units should be retired, representing total horsepower of 39,758. Based on this review, at September 30, 2019, we recorded a $1.5 million non-cash loss on the retirement of rental equipment to reduce the book value of these units to zero.

Our operating (loss) income decreased to a loss of $12.8 million from income of $532,000 for the nine months ended September 30, 2019 compared to the same period ended 2018. This decrease was due to an increased inventory allowance, loss on the retirement of rental units, and a goodwill impairment charge recorded in third quarter of 2019 that totaled $14.9 million, partially offset by higher rental revenues and compressor sales.

Selling, general, and administrative expense increased to $8.0 million from $6.7 million, for the nine months ended September 30, 2019, as compared to the same period ended September 30, 2018, largely due to an increase in officer incentive bonuses and stock compensation.

Depreciation and amortization expense increased to $17.1 million for the nine months ended September 30, 2019, compared to $16.4 million for the period ended September 30, 2018. This increase was the result of large horsepower units being added to the fleet. We added 60 units (approximately 56,000 horsepower) to our fleet over the past 12 months. Forty-two of these were 400 horsepower or larger, representing 95% of the horsepower added.

We recorded income tax benefit of $890,000 for the nine months ended September 30, 2019 compared to income tax expense of $3,000 for the three months ended September 30, 2018. For interim periods, our income tax benefit 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 rates of 21%. The change in tax benefit was primarily a result of a loss before provision for income taxes of $12.2 million during the nine months ended September 30, 2019, which was largely due to goodwill impairment, an increased inventory allowance, and retirement of rental equipment that totaled $14.9 million.

Total current liabilities	12,729		10,946
Total working capital	$	52,688	$	85,453

For the nine months ended September 30, 2019, we invested $53.4 million in property and equipment. During these nine months, we added $48.4 million in new equipment to our rental fleet, $3.8 million in payments related to the construction of our new corporate office, $430,000 in office furniture and equipment, and $1.5 million in vehicles. Our investment in property and equipment also includes any changes between work in progress related to rental fleet jobs started and those completed during the period. These changes result in a decrease to property and equipment of $845,000. Even though we have idle rental equipment, at times we do not have the specific type of equipment that our customers require, therefore we have to build new equipment to satisfy their needs. We financed this activity with cash flow from operations and cash on hand.

Cash flows

At September 30, 2019, we had cash and cash equivalents of $19.5 million compared to $52.6 million at December 31, 2018. Our cash flow from operations of $20.6 million was offset by capital expenditures of $53.4 million during the nine months ended September 30, 2019. We had working capital of $52.7 million at September 30, 2019 compared to $85.5 million at December 31, 2018. On September 30, 2019 and December 31, 2018, we had outstanding debt of $417,000, which is all related to our line of credit. We had positive net cash flow from operating activities of $20.6 million during the first nine months of 2019 compared to $23.0 million for the first nine months of 2018. The cash flow from operations of $20.6 million was primarily the result of adding back non-cash items of depreciation of $17.1 million, a loss on retirement of rental equipment of $1.5 million, an increased inventory allowance of $3.4 million, a goodwill impairment charge of $10.0 million, and stock-based compensation of $1.8 million against a net loss of $11.3 million and decreases in cash flows related to deferred income taxes of $0.9 million and changes in working capital of $0.9 million.

Strategy

For the remainder of the fiscal year 2019, our overall plan is to continue monitoring and holding expenses in line with the anticipated level of activity, fabricate rental fleet equipment only in direct response to market requirements, emphasize marketing of our idle gas compressor units and limit bank borrowing in line with market conditions. For the remainder of 2019, our forecasted capital expenditures with respect to compression equipment will be directly dependent upon our customers’ compression requirements and are not anticipated to exceed our internally generated cash flows and cash on hand. Any required capital will be for additions to our compressor rental fleet and/or addition or replacement of service vehicles. We believe that cash flows from operations, our current cash position and our line of credit will be sufficient to satisfy our capital and liquidity requirements for the foreseeable future. We may require additional capital to fund any unanticipated expenditures, including any acquisitions of other businesses, although that capital, beyond our line of credit, as discussed below may not be available to us when we need it or on acceptable terms.

Bank Borrowings

We have a senior secured revolving credit agreement the ("Amended Credit Agreement") with JP Morgan Chase Bank, N.A. (the "Lender") with an aggregate commitment of $30 million, subject to collateral availability. We also have a right to request from the lender, on an uncommitted basis, an increase of up to $20 million on the aggregate commitment (which could potentially increase the commitment amount to $50 million). On August 31, 2017, we amended and renewed the Amended Credit Agreement, extending the maturity date to December 31, 2020. No other material revisions were made to the credit facility. We had $29.5 million borrowing base availability at September 30, 2019 under the terms of our Amended Credit Agreement, and our balance on the line of credit was $417,000. For further information, see Note 7, "Credit Facility".

Contractual Obligations and Commitments

We have contractual obligations and commitments that affect the results of operations, financial condition and liquidity. The following table is a summary of our significant cash contractual obligations as of September 30, 2019:

Off-Balance Sheet Arrangements

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, 2019, the off-balance sheet arrangements and transactions that we have entered into include operating lease agreements and purchase agreements. We do not believe that these arrangements are reasonably likely to materially affect our liquidity, availability of, or requirements for, capital resources.

Special Note Regarding Forward-Looking Statements

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, 2018 filed with the SEC.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

There have been no changes in the market risks disclosed in the Company's Form 10-K for the year ended December 31, 2018.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures.

An evaluation was carried out under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Vice President and Principal Accounting Officer, of the effectiveness of the design and of our “disclosure controls and procedures” (as such term is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended or, the “Exchange Act”) as of the end of the period covered by this report pursuant to Exchange Act Rule 13a-15. Based upon that evaluation, the President and Chief Executive Officer and our Vice President and Principal Accounting Officer have concluded that, as of the end of the period covered by this report, adjustments must be made to the design of our controls in order to maintain an effective control environment with formal accounting policies and controls. The evaluation is a continuation of a review process that started in the fourth quarter of 2018 when we determined that there was a material weakness in our internal controls over financial reporting related to our review of the tax provision. A material weakness is a deficiency, or a combination of control deficiencies, in internal control over financial reporting 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.

Material Weaknesses in Internal Control over Financial Reporting.

During the fourth quarter of fiscal year 2018, we identified a material weakness in internal controls over financial reporting related to our accounting and reporting of income tax (expense) benefit, the related balance sheet accounts and other comprehensive income. In detail, we did not design and maintain an effective control environment with formal accounting policies and controls to adequately provide sufficient information for the preparation of our tax provision to our third party tax

professionals and did not provide an appropriate level or sufficient review of the tax provision. The material weakness created a reasonable possibility that there could be a material misstatement of our annual or interim financial statements.

This material weakness resulted in a material misstatement in the provision for income taxes in our consolidated financial statement as of and for the years ended December 31, 2017, 2016 and 2015. The misstatements were not material to any individual year. Consolidated financial statements included in Annual Report on Form 10-K issued as of December 31, 2018 reflect the correction of the material misstatement of income tax (expense) benefit, the related consolidated balance sheet and the consolidated income statement accounts.

We have undergone evaluations, enhancements and implementation in our internal controls over financial reporting, regarding and to address the identified material weakness and significant deficiency. We have implemented various changes and enhancements to improve our controls related to the material weakness and significant deficiency over financial reporting. Management believes that the implementation of these changes will remediate the material weakness described above. Nevertheless, these changes remain subject to further testing at the end of the year.

There have been no other changes in our internal control over financial reporting that occurred during our fiscal quarter ended September 30, 2019, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

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 flow. We are not currently a party to any material legal proceedings and we are not aware of any threatened litigation.
