EXPLANATORY NOTE

This Amendment No. 2 (“Amendment No. 2”) to the Quarterly Report on Form 10-Q/A amends the Quarterly Report on Form 10-Q of Enservco Corporation as of and for the quarter ended March 31, 2021, as filed with the Securities and Exchange Commission (“SEC”) on May 13, 2021 (the “Original Filing”), and as amended and filed with the SEC on April 11, 2022 ("Amendment No. 1").

The Company has re-evaluated its accounting for income taxes in connection with a change in control that occurred pursuant to the issuance of 4,199,998 shares of common stock during the first quarter of 2021. This change in control led to a change in management's judgment about the realizability of the Company's deferred tax assets. Pursuant to such re-evaluation, the Company’s management has determined that for the three months ended March 31, 2021 the Company should have recognized deferred income tax expense through the recording of additional valuation allowance.

Therefore, on April 14, 2022, the Company’s management and the audit committee of the Company’s board of directors concluded that the Company’s unaudited interim financial statements included in the Original Filing, as amended by Amendment No. 1, should be restated to recognize the deferred tax liability associated with this limitation. As such, the Company is filing this Amendment No. 2 to affect such restatement.

The restatement has no impact on the Company’s cash position, revenues, operating expenses, loss from operations or Adjusted EBITDA as of and for the three months ended March 31, 2021.

We are filing this Amendment No. 2 to amend and restate the Original Filing, as previously amended by Amendment No. 1, with modification as necessary to reflect the restatement. The following items have been amended to reflect the restatement: (i) Part I, Item 1. Financial Statements; and (ii) Part I, Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations. In addition, the Company’s Principal Executive Officer and Interim Principal Financial Officer has provided new certifications dated as of the date of this filing in connection with this Form 10-Q/A (Exhibits 31.1 and 32).

As a result of the factors described above, the Company’s management has concluded that a material weakness existed in the Company’s internal control over financial reporting and that the Company’s disclosure controls and procedures were not effective. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the financial statements will not be prevented or detected and corrected on a timely basis. For a discussion of management’s consideration of the material weakness identified, see Part I, Item 4. Controls and Procedures included in this Amendment No. 2.

Except as described above, no other information included in the Original Filing, as amended by Amendment No. 1, is being amended or updated by this Amendment No. 2. This Amendment No. 2 continues to describe the conditions as of the date of the Original Filing. Except as expressly contained herein, we have not updated, modified or supplemented the disclosures contained in the Original Filing or Amendment No. 1, and this Amendment No. 2 does not purport to reflect any information or events subsequent to the date of the Original Filing. Accordingly, this Amendment No. 2 should be read in conjunction with the Original Filing, Amendment No. 1 and with our filings with the SEC subsequent to the Original Filing.

Note 2 – Restatement of Previously Issued Financial Statements

In accordance with Accounting Standards Codification ("ASC") 740, and pursuant to re-evaluation by the Company's management, the Company has determined that for the three months ended March 31, 2021 the Company should have recognized deferred income tax expense through the recording of additional valuation allowance. This limitation is due to a change in control that occurred in February 2021 pursuant to the issuance of 4,199,998 shares of Company common stock.

The following tables summarize the effects of the restatement on each financial statement line item as of the date, and for the period, indicated (in thousands except per share amounts):

Note 3 - Summary of Significant Accounting Policies

Recent Developments

On August 10, 2017, we entered into the 2017 Credit Agreement, as amended, with East West Bank (the "2017 Credit Agreement") which provided for a three-year, $37.0 million senior secured revolving credit facility (the "Credit Facility"). On September 23, 2020, the Company and East West Bank entered into the Fifth Amendment to Loan and Security Agreement and Waiver (the "Fifth Amendment") which, among other things, provided for a loan concession of $16.0 million in exchange for 533,334 shares of Company common stock and a warrant to purchase up to 1,000,000 additional shares of Company common stock in the future, as well as further extending the maturity date for the repayment of the Credit Facility to October 15, 2021. On February 1, 2021, we entered into the Sixth Amendment to Loan and Security Agreement (the "Sixth Amendment") which extended the maturity date of the loan for an additional year to October 15, 2022, and modified certain covenants. On April 26, 2021, we entered into the Seventh Amendment to Loan and Security Agreement (the "Seventh Amendment") which provided for amortization of the loan on a 10-year straight-line basis commencing on November 15, 2021. As the terms of the Seventh Amendment were contemplated prior to March 31, 2021, the principal payments due over the next twelve months have been classified as current on the consolidated balance sheets as of March 31, 2021.

On August 13, 2020, the Company's Board of Directors approved a transaction to exchange 50%, or $1.25 million, of our subordinated debt with Cross River Partners, L.P., a related party, as well as $265,000 in accrued interest, for 403,602 shares of Company common stock. This transaction was finalized on September 15, 2020. On February 3, 2021, Cross River Partners, L.P. converted the remaining principal amount of such subordinated debt, or $1.25 million, as well as $62,000 in accrued interest, for 601,674 shares of Company common stock, at a conversion price equal to $2.18 per share, which was the closing price of the Company's stock reported on the NYSE American on the date of the conversion. In connection with such conversion, the Company issued a warrant to Cross River Partners, L.P. to purchase up to 150,418 additional shares of Company common stock in the future at an exercise price of $2.507 per share. The warrant for the 150,418 shares has a five-year term and is exercisable beginning February 3, 2022 until February 3, 2026. The issuance of the warrant at its grant date fair value of $2.02 per share caused the Company to record a loss of approximately $304,000 upon the conversion of the subordinated debt in the first quarter of 2021.

On September 28, 2020, the Company filed a final prospectus to its registration statement on Form S-3 (the "Shelf Registration Statement") that was filed with the Securities and Exchange Commission (the "SEC") on July 24, 2020, and declared effective on August 20, 2020. On September 29, 2020, pursuant to the Shelf Registration Statement, the Company, through its sales agent Alliance Global Partners ("AGP"), commenced an at-the-market offering (the "ATM Offering") which was designed to raise capital by issuing securities into the trading market, over-time, at the then-market price of the securities at the time they are sold. The Company sold 1,694,219 shares of Company common stock in the ATM Offering and collected net proceeds of $3.5 million.

On February 8, 2021, the Company entered into an Underwriting Agreement with AGP for a firm commitment underwritten public offering of the Company’s common stock pursuant to a registration statement on Form S-1 originally filed with the SEC on January 21, 2021 and declared effective on February 8, 2021 (the "February 2021 Public Offering"). Pursuant to the Underwriting Agreement, the Company issued and sold 4,199,998 shares of Company common stock, including shares issued and sold pursuant to AGP’s over-allotment option, at a public offering price of $2.30 per share. The Company collected net proceeds of $8.8 million in the February 2021 Public Offering, which closed on February 10, 2021. The Company made a $3.0 million principal payment on the Credit Facility upon the closing of the February 2021 Public Offering.

Recent Market Conditions

The COVID-19 pandemic has significantly impacted the world economic conditions including in the United States, with significant effects beginning in February 2020, and continuing through the issuance of this report, as federal, state and local governments react to the public health crisis, creating significant uncertainties relating to the United States economy. Consequently, the Company has experienced and expects to further experience a material adverse impact on its revenues, results of operations and cash flows. COVID-19 related quarantines and business restrictions have had a depressing impact on United States oil demand, and hence our business, which continues through the filing date of this report. The situation continues to change rapidly and additional impacts to our business may arise that we are not aware of currently. We cannot predict whether, when or the manner in which the conditions surrounding COVID-19 will change including the timing of lifting any restrictions or office closure requirements.

In addition, certain producing countries within the Organization of Petroleum Exporting Countries and their allies ("OPEC+") group attempted to increase market share through pricing activity that has had limited impact on the severe decline in domestic oil prices that occurred during the first quarter of 2020, and drilling and operating activity within our markets has remained depressed. There is no assurance that such efforts will not re-occur in the future.

The full extent of the impact of COVID-19 and OPEC+ actions on our operations and financial performance depends on future developments that are uncertain and unpredictable, including the duration and spread of the pandemic, its impact on capital and financial markets, any new information that may emerge concerning the severity of the virus, its spread to other regions as well as the actions taken to contain it, production response of domestic oil producers to lower oil prices, and the adherence to and continuity of OPEC+ production cuts, among others.

Cash and Cash Equivalents

The Company considers all highly liquid instruments purchased with an original maturity of three months or less to be cash equivalents. The Company continually monitors its positions with, and the credit quality of, the financial institutions with which it invests. Enservco maintains its excess cash in various financial institutions, where deposits may exceed federally insured amounts at times. 

Accounts Receivable

Accounts receivable are stated at the amounts billed to customers, net of an allowance for uncollectible accounts. The Company provides an allowance for uncollectible accounts based on a review of outstanding receivables, historical collection information and existing economic conditions. The allowance for uncollectible amounts is continually reviewed and adjusted to maintain the allowance at a level considered adequate to cover future losses. The allowance is management's best estimate of uncollectible amounts and is determined based on historical collection experience related to accounts receivable coupled with a review of the current status of existing receivables. The losses ultimately incurred could differ materially in the near term from the amounts estimated in determining the allowance. As of March 31, 2021, and December 31, 2020, the Company had an allowance for doubtful accounts of approximately $359,000 and $322,000, respectively. For the three months ended March 31, 2021 and 2020, the Company recorded approximately $38,000 and $300,000 to bad debt expense, respectively.

Inventories

Inventory consists primarily of propane, diesel fuel and chemicals that are used in the servicing of oil wells and is carried at the lower of cost or net realizable value in accordance with the first in, first out method (FIFO). The Company periodically reviews the value of items in inventory and provides write-downs or write-offs, of inventory based on its assessment of market conditions. Write-downs and write-offs are charged to cost of goods sold. For the three months ended March 31, 2021 and 2020, the Company did not recognize any write-downs or write-offs of inventory.

10

Property and Equipment

Property and equipment consist of (i) trucks, trailers and pickups; (ii) water transfer pumps, pipe, lay flat hose, trailers, and other support equipment; (iii) real property which includes land and buildings used for office and shop facilities and wells used for the disposal of water; (iv) other equipment such as tools used for maintaining and repairing vehicles, and (v) office furniture and fixtures, and computer equipment. Property and equipment is stated at cost less accumulated depreciation. The Company capitalizes interest on certain qualifying assets that are undergoing activities to prepare them for their intended use. Interest costs incurred during the fabrication period are capitalized and amortized over the life of the assets. The Company did not capitalize any interest during the three months ended March 31, 2021 or 2020. The Company charges repairs and maintenance against income when incurred and capitalizes renewals and betterments, which extend the remaining useful life, expand the capacity or efficiency of the assets. Depreciation is recorded on a straight-line basis over estimated useful lives of 5 to 30 years.

Any difference between net book value of the property and equipment and the proceeds of an assets’ sale or settlement of an insurance claim is recorded as a gain or loss in the Company’s earnings.

Leases

The Company assesses whether an arrangement is a lease at inception. Leases with an initial term of 12 months or less are not recorded on the balance sheet. We have elected the practical expedient to not separate lease and non-lease components for all assets. Operating lease assets and operating lease liabilities are calculated based on the present value of the future minimum lease payments over the lease term at the lease start date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease start date in determining the present value of future payments. The operating lease asset is increased by any lease payments made at or before the lease start date and reduced by lease incentives and initial direct costs incurred. The lease term includes options to renew or terminate the lease when it is reasonably certain that we will exercise that option. The exercise of lease renewal options is at our sole discretion. The depreciable life of lease assets and leasehold improvements are limited by the lease term. Lease expense for operating leases is recognized on a straight-line basis over the lease term.

The Company conducts a major part of its operations from leased facilities. Each of these leases is accounted for as an operating lease. Operating lease assets and liabilities are recognized at the lease commencement date. Operating lease liabilities represent the present value of lease payments not yet paid. Operating lease assets represent our right to use an underlying asset and are based upon the operating lease liabilities adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of operating lease assets.

The Company amortizes leasehold improvements over the shorter of the life of the lease or the life of the improvements. 

The Company has leased trucks and equipment in the normal course of business, which may be recorded as operating or finance leases, depending on the term of the lease. The Company recorded rental expense on equipment under operating leases over the lease term as it becomes payable; there were no rent escalation terms associated with these equipment leases. The Company records amortization expense on equipment under finance leases on a straight-line basis as well as interest expense based on our implicit borrowing rate at the date of the lease inception. The equipment leases contain purchase options that allow the Company to purchase the leased equipment at the end of the lease term, based on the market price of the equipment at the time of the lease termination. 

11

Long-Lived Assets

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recovered. During the first quarter of 2021, the Company concluded that there were no further triggering events which could indicate impairment of its long-lived assets. During the first quarter of 2020, the combination of the COVID-19 pandemic and actions taken by the OPEC+ countries caused oil and gas commodity demand to decrease significantly. The Company determined that these were triggering events which could indicate impairment of its long-lived assets. The Company reviewed both qualitative and quantitative aspects of the business during the analysis of impairment. During the quantitative review, the Company reviews the undiscounted future cash flows in its assessment of whether long-lived assets have been impaired. The Company determined that there was no impairment of its long-lived assets during the three months ended March 31, 2021.

Assets Held for Sale

The Company classifies long-lived assets to be sold as held for sale in the period in which all of the following criteria are met: (1) management, having the authority to approve the action, commits to a plan to sell the asset or disposal group; (2) the asset or disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets; (3) an active program to locate a buyer and other actions required to complete the plan to sell the asset or disposal group have been initiated; (4) the sale of the asset or disposal group is probable, and transfer of the asset or disposal group is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond our control extend the period of time required to sell the asset or disposal group beyond one year; (5) the asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (6) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.

We initially measure a long-lived asset or disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held-for-sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset or disposal group until the date of sale. We assess the fair value of a long-lived asset or disposal group less any costs to sell each reporting period it remains classified as held for sale and report any subsequent changes as an adjustment to the carrying value of the asset or disposal group, as long as the new carrying value does not exceed the carrying value of the asset at the time it was initially classified as held for sale. During the years three months ended March 31, 2021 and 2020, the Company recorded no impairment charges on its held for sale assets.

Upon determining that a long-lived asset or disposal group meets the criteria to be classified as held for sale, the Company ceases depreciation and reports long-lived assets and/or the assets and liabilities of the disposal group, if material, in the line items assets held for sale in our consolidated balance sheets.

Goodwill and Other Intangible Assets

Goodwill represents the excess purchase price over the fair value of identifiable assets received attributable to business acquisitions and combinations. Goodwill and other intangible assets are measured for impairment at least annually and/or whenever events and circumstances arise that indicate impairment may exist, such as a significant adverse change in the business climate. In assessing the value of goodwill, assets and liabilities are assigned to the reporting units and the appropriate valuation methodologies are used to determine fair value at the reporting unit level. Identified intangible assets are amortized using the straight-line method over their estimated useful lives.

During the first quarter of 2021, the Company concluded that there were no further triggering events which could indicate impairment of its goodwill and other intangible assets. During the first quarter of 2020, the combination of the COVID-19 pandemic and actions taken by the OPEC+ countries caused oil and gas commodity demand to decrease significantly. The Company determined that these were triggering events which could indicate impairment of its goodwill and other intangible assets. The Company reviewed both qualitative and quantitative aspects of the business during the analysis of impairment. During the quantitative review, the Company uses both the fair value and discounted future cash flows in its assessment of whether goodwill and other intangible assets have been impaired. The Company determined that there was no impairment of its goodwill and other intangible assets during the three months ended March 31, 2020.

Revenue Recognition 

The Company evaluates revenue when we can identify the contract with the customer, the performance obligations in the contract, the transaction price, and we are certain that the performance obligations have been met. Revenue is recognized when the service has been provided to the customer. The vast majority of the Company's services and product offerings are short-term in nature. The time between invoicing and when payment is due under these arrangements is generally 30 to 60 days. Revenue is not generated from contractual arrangements that include multiple performance obligations.

The Company’s agreements with its customers are often referred to as “price sheets” and sometimes provide pricing for multiple services. However, these agreements generally do not authorize the performance of specific services or provide for guaranteed throughput amounts. As customers are free to choose which services, if any, to use based on the Company’s price sheet, the Company prices its separate services on the basis of their standalone selling prices. Customer agreements generally do not provide for performance, cancellation, termination, or refund type provisions. Services based on price sheets with customers are generally performed under separately issued “work orders” or “field tickets” as services are requested.

Revenue is recognized for certain projects that take more than one day projects over time based on the number of days during the reporting period and the agreed upon price as work progresses on each project.

Disaggregation of revenue

See Note 12 - Segment Reporting for disaggregation of revenue.

Earnings (Loss) Per Share 

Earnings per Common Share - Basic is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Earnings per Common Share - Diluted earnings is calculated by dividing net income (loss) by the diluted weighted average number of common shares. The diluted weighted average number of common shares is computed using the treasury stock method for common stock that may be issued for outstanding stock options, restricted stock and warrants.

As of March 31, 2021 and 2020, there were outstanding stock options, unvested restricted stock awards and warrants to acquire an aggregate of 1,383,489 and 247,048 shares of Company common stock, respectively, which have a potentially dilutive impact on earnings per share. As of March 31, 2021 and 2020, the outstanding stock options and warrants had no aggregate intrinsic value (the difference between the estimated fair value of the Company’s common stock on March 31, 2021 and 2020, and the exercise price, multiplied by the number of in-the-money instruments). Dilution is not permitted if there are net losses during the period. As such, the Company does not show diluted earnings per share for the three months ended March 31, 2021 and 2020.

12

Income Taxes

The Company recognizes deferred tax liabilities and assets based on the differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements that will result in taxable or deductible amounts in future years. 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 of a change in tax rates on deferred tax assets and liabilities will be recognized in income in the period that includes the enactment date. A deferred tax asset or liability that is not related to an asset or liability for financial reporting is classified according to the expected reversal date. The Company records a valuation allowance to reduce deferred tax assets to an amount that it believes is more likely than not expected to be realized.

The Company accounts for any uncertainty in income taxes by recognizing the tax benefit from an uncertain tax position only if, in the Company’s opinion, it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The Company measures the tax benefits recognized in the financial statements from such a position based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. The application of income tax law is inherently complex. Laws and regulations in this area are voluminous and are often ambiguous.  As such, the Company is required to make many subjective assumptions and judgments regarding income tax exposures. Interpretations of and guidance surrounding income tax law and regulations change over time and may result in changes to the Company’s subjective assumptions and judgments which can materially affect amounts recognized in the consolidated balance sheets and consolidated statements of income. The result of the reassessment of the Company’s tax positions did not have an impact on the consolidated financial statements.

Interest and penalties associated with tax positions are recorded in the period assessed as Other expense. The Company files income tax returns in the United States and in the states in which it conducts its business operations. The Company’s United States federal income tax filings for tax years 2017 through 2020 remain open to examination. In general, the Company’s various state tax filings remain open for tax years 2016 to 2020.

Fair Value

The Company follows authoritative guidance that applies to all financial assets and liabilities required to be measured and reported on a fair value basis. The Company also applies the guidance to non-financial assets and liabilities measured at fair value on a nonrecurring basis, including non-competition agreements and goodwill. The guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date.  The guidance establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available.

Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions of what market participants would use in pricing the asset or liability based on the best information available in the circumstances.  Beginning in 2017 the Company valued its warrants using the Binomial Lattice model ("Lattice"). Specific inputs used in the Lattice are the underlying stock price, the exercise price of the warrant, expected dividends, historical volatility, term to expiration and risk-free interest rates. The Company did not have any transfers between hierarchy levels during the three months ended March 31, 2021. The financial and nonfinancial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement.

The hierarchy is broken down into three levels based on the reliability of the inputs as follows:

Level 1: Quoted prices are available in active markets for identical assets or liabilities;

Level 2: Quoted prices in active markets for similar assets and liabilities that are observable for the asset or liability; or

Level 3: Unobservable pricing inputs that are generally less observable from objective sources, such as discounted cash flow models or valuations.

13

Stock-based Compensation

Stock-based compensation cost is measured at the date of grant, based on the calculated fair value of the award as described below, and is recognized over the requisite service period, which is generally the vesting period of the equity grant.

The Company uses the Black-Scholes pricing model as a method for determining the estimated grant date fair value for all stock options awarded to employees, independent contractors, officers, and directors. The expected term of the options is based upon evaluation of historical and expected exercise behavior. The risk-free interest rate is based upon U.S. Treasury rates at the date of grant with maturity dates approximately equal to the expected life of the grant. Volatility is determined upon historical volatility of our stock and adjusted if future volatility is expected to vary from historical experience. The dividend yield is assumed to be none as we have not paid dividends, nor do we anticipate paying any dividends in the foreseeable future.

The Company uses a Lattice model to determine the fair value of certain warrants. The expected term used was the remaining contractual term. Expected volatility is based upon historical volatility over a term consistent with the remaining term. The risk-free interest rate is derived from the yield on zero-coupon U.S. government securities with a remaining term equal to the contractual term of the warrants. The dividend yield is assumed to be zero.

The Company used the market-value of Company stock to determine the fair value of the performance-based restricted stock awarded in 2018 and 2019. Stock based compensation is updated quarterly based on actual forfeitures. The Company used either a Lattice model or the Black-Scholes pricing model to determine the fair value of market-based restricted stock awarded in 2021 and 2020.

Management Estimates

The preparation of the Company’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include the realization of accounts receivable, evaluation of impairment of long-lived assets, stock-based compensation expense, income tax provision and the valuation of deferred taxes. Actual results could differ from those estimates.

Reclassifications

Certain prior-period amounts have been reclassified for comparative purposes to conform to the current presentation. These reclassifications have no effect on the Company’s consolidated statement of operations.

Accounting Pronouncements 

In June 2016, the FASB issued ASU 2016-13, Financial Statements - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires companies to measure credit losses utilizing a methodology that reflects expected credit losses and requires a consideration of a broader range of reasonable and supportable information to ascertain credit loss estimates. The standard is effective for fiscal years beginning after December 15, 2022. The Company does not expect the adoption of ASU 2016-13 to have a material impact on its consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles of Topic 740, and improves consistent application by clarifying and amending existing guidance. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements. The standard is effective for fiscal years beginning after December 15, 2020. The Company adopted ASU 2019-12 on January 1, 2021, and the adoption did not have a material impact on its consolidated financial statements.

Note 6 – Discontinued Operations 

Heat Waves Water Management

During December 2019, the Heat Waves Water Management business ceased operations. The decision to discontinue HWWM was made due to its history of net losses, declining revenues, and its failure to generate positive operating cash flow. In early 2020, the Company began disposing of the HWWM assets and plans on selling the remaining HWWM assets during the remainder of 2021.

Note 7 – Debt

East West Bank Revolving Credit Facility

The 2017 Credit Agreement (as defined in Note 3) originally allowed us to borrow up to 85% of our eligible receivables and up to 85% of the appraised value of our eligible equipment. The Fifth Amendment restructured the loan and provided for a loan forgiveness of $16.0 million and converts the remaining principal balance to a $17.0 million equipment term loan and a revolver to provide the Company with a maximum $1.0 million line of credit. The Sixth Amendment further extended the maturity date and modified the financial covenants effective January 1, 2021. There are no required principal payments until maturity on October 15, 2022, and interest is fixed at 8.25%. Interest on the first 5.25% is calculated monthly and paid in arrears, while the remaining 3.00% is accrued to the loan balance through October 15, 2021, and due with all remaining outstanding principal on the maturity date. Additionally, the Credit Facility is subject to an unused credit line fee of 0.5% per annum multiplied by the amount by which total availability exceeds the average monthly balance of the Credit Facility, payable monthly in arrears. The Credit Facility is collateralized by substantially all our assets and subject to financial covenants.

On February 11, 2021, the Company made a $3.0 million payment of principal on the equipment term loan. As of March 31, 2021, we had an outstanding principal loan balance under the Credit Facility of approximately $15.2 million with a weighted average interest rates of 8.25% per year. As of March 31, 2021, our availability under the amended 2017 Credit Agreement was $1.0 million. The Credit Facility balance of $15.2 million at March 31, 2021 includes $1.2 million of future interest payable due over the remaining term of the Credit Facility in accordance with ASC 470-60, Troubled Debt Restructuring by Debtors.

Under the amended 2017 Credit Agreement, we are subject to the following financial covenants, with which we were in compliance as of March 31, 2021:

(1) 

On December 31, 2020, we were required to maintain liquidity of not less than $1.5 million; and

(2) 

For each trailing three-month period, commencing with the three-month period ending March 31, 2021, we are required to achieve gross revenue of at least seventy percent (70%) of our projected gross revenue; and

(3) We are limited to a capital expenditures cap of $1.2 million for any fiscal year that the loan remains outstanding.

In connection with amending the 2017 Credit Agreement on September 23, 2020, the Company issued to East West Bank 533,334 shares of Company common stock, and a five-year warrant to purchase up to 1,000,000 additional shares of Company common stock at an exercise price of $3.75 per share. The 533,334 shares of Company common stock were valued at a price of $2.0775 per share, or a total value of $1.1 million. The 533,334 common shares issued to East West Bank could not be sold or transferred prior to March 23, 2021. The warrant for 1,000,000 shares is exercisable beginning September 23, 2021 until September 23, 2025. The fair value of the warrant was determined to be $1.4 million and were recorded in additional paid-in capital. The Company recorded a total gain on the debt restructuring of $11.9 million during the third quarter of 2020, which was calculated by subtracting from the $16.0 million loan forgiveness, a) the future interest payable on the Credit Facility; b) the value of the Company common stock issued; and c) the fair value of the warrant.

Debt Issuance Costs

We capitalized certain debt issuance costs incurred in connection with the Credit Facility discussed above and these costs were amortized to interest expense over the term of the facility on a straight-line basis. There were no remaining unamortized debt issuance costs as of March 31, 2021, and December 31, 2020. During the three months ended March 31, 2020, the Company amortized approximately $35,000 of these costs to Interest Expense.

Note 8 – Income Taxes 

Income tax expense during interim periods is based on applying an estimated annual effective income tax rate to year-to-date income, plus any significant unusual or infrequently occurring items which are recorded in the interim period.  The provision for income taxes for the three months ended March 31, 2021 and 2020 differs from the amount that would be provided by applying the statutory U.S. federal income tax rate of 21% to pre-tax income primarily because of state income taxes and estimated permanent differences.

The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including, but not limited to, the expected operating income for the year, projections of the proportion of income earned and taxed in various jurisdictions, permanent and temporary differences, and the likelihood of recovering deferred tax assets generated in the current year.  The accounting estimates used to compute the provision for income taxes may change as new events occur, more experience is obtained, additional information becomes known or as the tax environment changes.

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment.

As discussed in the Explanatory Note above, during the three months ended March 31, 2021, the Company experienced a change in control pursuant to the issuance of 4,199,998 shares of common stock. As a result of this change in control, and in accordance with Internal Revenue Service Code Section 382, the realizability of the Company's deferred tax assets became limited. Based on management's judgment, the Company estimates that as of March 31, 2021, $1.4 million of deferred tax liabilities could reverse without an offsetting deferred tax asset. Due to this, the Company has recognized $1.4 million of deferred income tax expense for the three months ended March 31, 2021. For the three months ended March 31, 2020, the Company's income tax benefit of $0.7 million was adjusted by the valuation allowance which resulted in a net tax provision of zero.

Note 9 – Commitments and Contingencies 

Operating Leases

Operating lease assets and liabilities are recognized at the lease commencement date. Operating lease liabilities represent the present value of lease payments not yet paid. Operating lease assets represent our right to use an underlying asset and are based upon the operating lease liabilities adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of operating lease assets. To determine the present value of lease payments not yet paid, the Company uses the weighted average interest rate on its Credit Facility. Long-term leases typically contain rent escalations over the lease term. The Company recognizes expense for these leases on a straight-line basis over the lease term.

The Company has elected the short-term lease recognition exemption for all applicable classes of underlying assets. Short-term disclosures include only those leases with a term greater than one month and 12 months or less, and expense is recognized on a straight-line basis over the lease term. Leases with an initial term of 12 months or less, that do not include an option to purchase the underlying asset that we are reasonably certain to exercise, are not recorded on the balance sheet.

The Company elected the expedient to account for lease and non-lease components as a single component for our entire population of operating lease assets.

As of March 31, 2021, the Company leases facilities and certain equipment under lease commitments that expire through June 2026. Future minimum lease commitments for these operating lease commitments are as follows (in thousands):

Twelve Months Ending March 31,	Operating Leases			Finance Leases
2022	$	948		$	99
2023		709			20
2024		645			14

Self-Insurance

In June 2015, the Company became self-insured under its Employee Group Medical Plan, and currently is responsible to pay the first $50,000 in medical costs per individual participant for claims incurred in the calendar year up to a maximum of approximately $1.8 million per year in the aggregate based on enrollment. The Company had an accrued liability of approximately $108,000 and $150,000 as of March 31, 2021 and December 31, 2020, respectively, for insurance claims that it anticipates paying in the future related to claims that occurred prior to December 31, 2020. Effective January 1, 2021, the Company moved onto a traditional Employee Group Medical Plan and was no longer self-insured for claims occurring after that date.

Effective April 1, 2015, the Company had entered into a workers’ compensation and employer’s liability insurance policy with a term through March 31, 2018.  Under the terms of the policy, the Company was required to pay premiums in addition to a portion of the cost of any claims made by our employees, up to a maximum of approximately $1.8 million over the term of the policy (an amount that was variable with changes in annualized compensation amounts). As of March 31, 2021, a former employee of ours had an open claim relating to injuries sustained while in the course of employment, and the projected maximum cost of the policy as determined by the insurance carrier included estimated claim costs that have not yet been paid or incurred in connection with the claim. During the year ended December 31, 2017, our insurance carrier formally denied the workers' compensation claim and has moved to close the claim entirely. Per the terms of our insurance policy, through March 31, 2021, we had paid in approximately $1.8 million of the projected maximum plan cost of $1.8 million, and had recorded approximately $1.6 million as expense over the term of the policy. In September 2020, the claim was officially denied by the Kansas Division of Workers Compensation Judicial Unit. As of March 31, 2021, no appeal has been made and the Company expects to collect the remaining $189,000 on deposit with the underwriter. Effective April 1, 2018, we entered into a new workers’ compensation policy with a fixed premium amount determined annually, and therefore are no longer partially self-insured for workers' compensation and employer's liability.

Note 10– Stockholders’ Equity

Warrants

In June 2016, the Company granted a principal of the Company’s investor relations firm warrants to acquire 2,000 shares of the Company’s common stock in connection with a reduction of the firm's ongoing monthly cash service fees. The warrants had a grant-date fair value of $5.40 per share and vested over a one-year period, 1,000 on December 21, 2016 and 1,000 on June 21, 2017. As of March 31, 2021, all of these warrants remain outstanding and are exercisable until June 21, 2021 at $10.50 per share.

On November 11, 2019, in connection with a subordinated loan agreement, the Company granted Cross River one five-year warrant to buy an aggregate total of 41,667 shares of the Company's common stock at an exercise price of $3.00 per share. The warrants had a grant-date fair value $2.40 and were fully vested upon issuance and remain outstanding and exercisable until November 11, 2024.

On September 23, 2020, in connection with the Fifth Amendment, the Company granted East West Bank one five-year warrant to buy an aggregate total of 1,000,000 shares of the Company's common stock at an exercise price of $3.75 per share. The warrants had a grant-date fair value of $1.42, were fully vested upon issuance and remain outstanding and are exercisable beginning one-year from the issuance date on September 23, 2021 and until September 23, 2025.

On February 11, 2021, in connection with the conversion of the subordinated loan agreement to Company common stock, the Company granted Cross River one five-year warrant to buy an aggregate total of 150,418 shares of the Company's common stock at an exercise price of $2.507 per share. The warrants had a grant-date fair value $2.02 per share and are exercisable beginning one-year from the issuance date on February 11, 2022 until February 11, 2026.

All warrants granted to Cross River were reviewed and approved by the independent directors of the Company.

On April 12, 2021, the SEC issued a Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies ("SPACs")(the "Staff Statement"). The SEC highlighted accounting considerations which could, in certain circumstances, indicate that warrants should be accounted for as liabilities rather than equity instruments, in which case the warrants would be subject to fair value adjustments during each reporting period. Although the Staff Statement focused on SPACs, the same accounting considerations may apply to warrants issued by non-SPAC entities. Upon issuance of the Staff Statement, the Company performed further analysis on its population of warrants, which are listed above, giving consideration to the areas of concern noted in the Staff Statement. Upon this further review of its warrant agreements, the Company determined that it has correctly accounted for its warrants as equity instruments.

Note 11 – Stock Options and Restricted Stock

Stock Options

On July 27, 2010, the Company’s Board of Directors adopted the 2010 Stock Incentive Plan (the “2010 Plan”). The aggregate number of shares of common stock that could be granted under the 2010 Plan was reset at the beginning of each year based on 15% of the number of shares of common stock then outstanding. As such, on January 1, 2016 the number of shares of common stock available under the 2010 Plan was reset to 381,272 shares based upon 2,541,809 shares outstanding on that date. Options were typically granted with an exercise price equal to the estimated fair value of the Company's common stock at the date of grant with a vesting schedule of one to three years and a contractual term of 5 years. As discussed below, the 2010 Plan has been replaced by a new stock option plan and no additional stock option grants will be granted under the 2010 Plan. As of March 31, 2021, there were options to purchase 1,079 shares outstanding under the 2010 Plan.

On July 18, 2016, the Board of Directors unanimously approved the adoption of the Enservco Corporation 2016 Stock Incentive Plan (the “2016 Plan”), which was approved by the stockholders on September 29, 2016. The aggregate number of shares of common stock that may be granted under the 2016 Plan is 533,334 shares plus authorized and unissued shares from the 2010 Plan totaling 159,448 for a total reserve of 692,782 shares. As of March 31, 2021, there were options to purchase 3,823 shares and we had granted restricted stock shares of 184,503 that remained outstanding under the 2016 Plan.

During the three months ended March 31, 2021 and 2020, no options were granted or exercised.

The following is a summary of stock option activity for all equity plans for the three months ended March 31, 2021:

	Shares			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (Years)
Outstanding at December 31, 2020		11,569		$	5.87		0.53
Forfeited or Expired		(6,667	)		5.55		-
Outstanding at March 31, 2021		4,902		$	6.31		0.94

Exercisable at March 31, 2021		4,902		$	6.31		0.94

There was no aggregate intrinsic value (the difference between the estimated fair value of the Company’s common stock on March 31, 2021, and the exercise price, multiplied by the number of in-the-money options) of our outstanding options.

During the three months ended March 31, 2021 and 2020, the Company recognized stock-based compensation costs for stock options of approximately $0 and $2,000, respectively, in sales, general, and administrative expenses. The Company currently expects all outstanding options to vest. Compensation cost is revised if subsequent information indicates that the actual number of options vested due to service is likely to differ from previous estimates. 

As of March 31, 2021, there was no remaining unrecognized compensation costs related to non-vested shares under the Company's stock option plans.

26

Restricted Stock

Restricted shares issued pursuant to restricted stock awards under the 2016 Stock Plan are restricted as to sale or disposition. These restrictions lapse periodically generally over a period of three years. Restrictions may also lapse for early retirement and other conditions in accordance with our established policies. Upon termination of employment, shares on which restrictions have not lapsed must be returned to us, resulting in restricted stock forfeitures. The fair market value on the date of the grant of the stock with a service condition is amortized and charged to income on a straight-line basis over the requisite service period for the entire award. The fair market value on the date of the grant of the stock with a performance condition shall be accrued and recognized when it becomes probable that the performance condition will be achieved. Restricted shares that contain a market condition are amortized and charged over the life of the award.

A summary of the restricted stock activity is presented below:

	Number of Shares			Weighted-Average Grant- Date Fair Value
Restricted shares at December 31, 2020		24,393		$	7.32
Granted		165,000			1.05
Vested		(3,667	)		7.05
Forfeited		(1,223	)		9.99
Restricted shares at March 31, 2021		184,503		$	1.70

During the three ended March 31, 2021 and 2020, the Company recognized stock-based compensation costs for restricted stock of approximately $24,000 and $36,000 in sales, general, and administrative expenses. Compensation cost is revised if subsequent information indicates that the actual number of restricted stock vested due to service is likely to differ from previous estimates.

The following table sets forth the weighted average outstanding of potentially dilutive instruments for the three months ended March 31, 2021 and 2020:

ITEM 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion provides information regarding the results of operations for the three months ended March 31, 2021 and 2020, and our financial condition, liquidity and capital resources as of March 31, 2021, and December 31, 2020. The financial statements and the notes thereto contain detailed information that should be referred to in conjunction with this discussion.

Forward-Looking Statements

The information discussed in this Quarterly Report includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934 (the “Exchange Act”). All statements, other than statements of historical facts, included herein concerning, among other things, planned capital expenditures, future cash flows and borrowings, pursuit of potential acquisition opportunities, our financial position, business strategy and other plans and objectives for future operations, are forward-looking statements. These forward-looking statements are identified by their use of terms and phrases such as “may,” “expect,” “estimate,” “project,” “plan,” “believe,” “intend,” “achievable,” “anticipate,” “will,” “continue,” “potential,” “should,” “could,” and similar terms and phrases. Although we believe that the expectations reflected in these forward-looking statements are reasonable, they do involve certain assumptions, risks and uncertainties. Our results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including, among others:      

● Our ability to maintain certain operating covenants under our existing Loan and Security Agreement, which if violated and not cured, could result in our outstanding loan balance being accelerated, due and payable;

● Our ability to successfully repay or refinance on terms acceptable to us the outstanding balance of the 2017 Credit Agreement when due in October 2022 unless earlier accelerated;

● Potential decreases in the prices for crude oil and natural gas which would likely result in exploration and production companies cutting back their capital expenditures for oil and gas well drilling which in turn would result in significantly reduced demand for our drilling completion services, thereby negatively affecting our revenues and results of operations;

● Competition for the services we provide in our areas of operations, which has increased significantly due to the recent fluctuations in prices for crude oil and natural gas;

● Constraints on us as a result of our indebtedness, including restrictions imposed on us under the terms of our Credit Facility agreement and our ability to generate sufficient cash flows to repay our debt obligations;

● Our capital requirements and uncertainty of obtaining additional funding on terms acceptable to us;

● The impact of general economic conditions on the demand for oil and natural gas and the availability of capital which may impact our ability to perform services for our customers;

● The geographical diversity of our operations which adds significantly to our costs of doing business;

● Our history of losses and working capital deficits which, at times, have been significant;

● Weather and environmental conditions, including the potential of abnormally warm winters in our areas of operations that adversely impact demand for our services;

● Our ability to retain key members of our senior management and key technical employees;

● The impact of environmental, health and safety and other governmental regulations, and of current or pending legislation with which we and our customers must comply;

● Developments in the global economy as well as pandemic risks related to the COVID-19 virus and resulting demand and supply for oil and natural gas;

● Risks relating to any unforeseen liabilities;

● Federal and state initiatives relating to the regulation of hydraulic fracturing; and

● The price and volume volatility of our common stock.

Finally, our future results will depend upon various other risks and uncertainties, including, but not limited to, those detailed in our filings with the SEC. For additional information regarding risks and uncertainties, please read our filings with the SEC under the Exchange Act and the Securities Act, including our Annual Report on Form 10-K for the fiscal year ended December 31, 2020. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements in this paragraph and elsewhere in this Quarterly Report. Other than as required under securities laws, we do not assume a duty to update these forward-looking statements, whether as a result of new information, subsequent events or circumstances, changes in expectations or otherwise.

Recent Market Conditions

The COVID-19 pandemic has significantly impacted the world economic conditions including in the United States, with significant effects beginning in February 2020, and continuing through the issuance of this report, as federal, state and local governments react to the public health crisis, creating significant uncertainties relating to the United States economy. Consequently, the Company has experienced and expects to further experience a material adverse impact on its revenues, results of operations and cash flows. COVID-19 related quarantines and business restrictions have had a depressing impact on United States oil demand, and hence our business, which continues through the filing date of this report. The situation continues to change rapidly and additional impacts to our business may arise that we are not aware of currently. We cannot predict whether, when or the manner in which the conditions surrounding COVID-19 will change including the timing of lifting any restrictions or office closure requirements.

In addition, certain producing countries within the Organization of Petroleum Exporting Countries and their allies ("OPEC+") group attempted to increase market share through pricing activity that has had limited impact on the severe decline in domestic oil prices that occurred during the first quarter of 2020, and drilling and operating activity within our markets has remained depressed. There is no assurance that such efforts will not re-occur in the future.

The full extent of the impact of COVID-19 and OPEC+ actions on our operations and financial performance depends on future developments that are uncertain and unpredictable, including the duration and spread of the pandemic, its impact on capital and financial markets, any new information that may emerge concerning the severity of the virus, its spread to other regions as well as the actions taken to contain it, production response of domestic oil producers to lower oil prices, and the adherence to and continuity of OPEC+ production cuts, among others.

RESULTS OF OPERATIONS

Executive Summary

Revenues for the three months ended March 31, 2021, decreased approximately $4.2 million, or 45%, from the comparable period last year due to weakness in domestic oil and gas activity levels, and the broader impact of the COVID-19 pandemic beginning in March 2020. Average North American rig count declined by 50% from 785 rigs in operation during the first quarter of 2020 to 393 rigs in operation during the first quarter of 2021.

Segment profits for the three-month period ended March 31, 2021, decreased by approximately $887,000, or 96%, due to the reasons noted above.  Sales, general & administrative expense decreased by approximately $757,000, or 43%, year-over-year due primarily to a decrease in our bad debt expense and a decrease in outside professional services. 

Net loss for the three months ended March 31, 2021, was approximately $3.9 million, or $0.42 per share, compared to a net loss of approximately $2.8 million, or $0.77 per share, in the same period last year due to the factors noted above.

Adjusted EBITDA for the three months ended March 31, 2021, was a loss of approximately $940,000 compared to a loss of approximately $503,000 for the same period last year. See the section titled Adjusted EBITDA* within this Item for definition of Adjusted EBITDA.

Industry Overview

During the three months ended March 31, 2021, WTI crude oil price averaged approximately $58 per barrel, versus an average of approximately $46 per barrel in the comparable period last year. The North American rig count declined to 417 rigs in operation as of March 31, 2021, compared to 728 rigs at the same time a year ago.  Despite the lower activity levels and reduced rig count, we have grown our customer base and allocated resources to the most active basins. We are focused on increasing utilization levels and optimizing the deployment of our equipment and workforce while maintaining high standards for service quality and safe operations. We compete on the basis of the quality, breadth of our service offerings, and price.

Beginning in early March of 2020, the market experienced a precipitous decline in oil prices in response to oil demand concerns due to the economic impacts of the COVID-19 virus and anticipated increases in supply from Russia and OPEC, particularly Saudi Arabia. We expect that our customers will continue to have lower activity during this period of significantly reduced North American oil rigs in operation.

Segment Overview

Segment Results:

Enservco’s reportable business segments are Production Services and Completion and Other Services. These segments have been selected based on management’s resource allocation and performance assessment in making decisions regarding the Company.

The following is a description of the segments.

Production Services: This segment utilizes a fleet of hot oil trucks and acidizing units to provide maintenance services to the domestic oil and gas industry. These services include hot oil services and acidizing services.

Completion and Other Services: This segment utilizes a fleet of frac water heating units to provide frac water heating services and related support services to the domestic oil and gas industry. These services also include other services for other industries, which consists primarily of hauling and transport of materials and heat treating for customers.

Unallocated includes general overhead expenses and assets associated with managing all reportable operating segments which have not been allocated to a specific segment.

The following tables set forth revenue from operations and segment profits for our business segments for the three months ended March 31, 2021 and 2020 (in thousands):

	Three Months Ended March 31,

Production Services

Production Services, which accounted for 36% of total revenue for the three months ended March 31, 2021, decreased approximately $1.4 million, or 42%, to $1.8 million compared to $3.2 million for the same quarter last year due to decreased activity levels related to the lower active oil rigs.

Hot oil revenue for the three months ended March 31, 2021, decreased approximately $1.1 million, or 39%, compared to the three months ended March 31, 2020, from approximately $2.9 million to approximately $1.8 million. The decrease was primarily due to the lower domestic oil and gas activity levels driven by lower active oil rigs.

Acidizing revenues for the three months ended March 31, 2021, decreased by approximately $225,000, or 83%, to approximately $45,000 from approximately $270,000.   The year-over-year decline was primarily driven by the reasons noted above. The Company continues to pursue customers and partner with chemical suppliers to develop new cost-effective acid programs in seeking to expand our acidizing services across our service areas. 

Segment loss for our Production services decreased by $169,000, or 58%, to a loss of $123,000 for the three months ended March 31, 2021, compared to loss of $292,000 in the same quarter last year, which was primarily the result of cost saving measures implemented to offset the industry conditions discussed above. 

Completion and Other Services

Completion and Other Services, which accounted for 64% of total revenue for the three months ended March 31, 2021, decreased approximately $2.9 million, or 47%, to $3.3 million compared to $6.2 million for the same quarter last year due to the aforementioned related downturn in the industry.

The segment profit for Completion and other services for the three months ended March 31, 2021, was approximately $157,000 compared to segment profit of approximately $1.2 million during the three months ended March 31, 2020. Decreased segment profit related to the reasons discussed above.

Geographic Areas

The Company operates solely in three geographically diverse regions of the United States. The following table sets forth revenue from operations for the Company’s three geographic regions during the three months ended March 31, 2021 and 2020 (in thousands):

	Three Months Ended March 31,

Total Revenues	$	5,143	$	9,386

Notes to tables:

(1) Includes the D-J Basin/Niobrara field (northeastern Colorado and southeastern Wyoming), the San Juan Basin (southeastern Colorado and Northeastern New Mexico), the Powder River and Green River Basins (northeastern and southwestern Wyoming), the Bakken area (western North Dakota and eastern Montana). 

(2) Includes the Scoop/Stack Shale in Oklahoma and the Eagle Ford Shale in Texas. 

(3) Consists of the southern region of the Marcellus Shale formation (southwestern Pennsylvania and northern West Virginia) and the Utica Shale formation (eastern Ohio). 

Production Services segment revenue in the Rocky Mountain Region for the three months ended March 31, 2021, decreased approximately $749,000, or 63%, primarily due to less acidizing and hot oiling activity in the D-J and Bakken Basins.

Production Services segment revenue in the Central USA region for the three months ended March 31, 2021, decreased by approximately $633,000, or 34%, due to a decrease in hot oiling and acidizing activity in the Eagle Ford Shale.

Production Services segment revenue in the Eastern USA region for the three months ended March 31, 2021, increased approximately $24,000, or 18%, resulting from increased hot oiling in the Marcellus and Utica Basins.

Completion and Other Services segment revenue in the Rocky Mountain Region for the three months ended March 31, 2021, decreased approximately $3.1 million, or 61%, primarily due to less completion activity in the D-J and Bakken Basins.

Completion and Other Services segment revenue in the Central USA Region for the three months ended March 31, 2021, decreased approximately $110,000, or 100%, primarily due to the closure of a location in the Anadarko Basin.

Completion and Other Services segment revenue in the Eastern USA region for the three months ended March 31, 2021, increased approximately $279,000, or 26%, resulting from increased frac water heating in the Marcellus and Utica Basins.

35

Historical Seasonality of Revenues

Because of the seasonality of our frac water heating business and, to a lesser extent, our hot oiling business, revenues generated during the cooler first and fourth quarters of our fiscal year, constitute our “heating season,” and are typically significantly higher than revenues during the second and third quarters of our fiscal year. In addition, the revenue mix of our service offerings changes outside our heating season as our Completion and other services (which includes frac water heating) typically decrease as a percentage of total revenues and our Production services increase as a percentage of total revenue. Thus, the revenues recognized in our quarterly financial statements in any given period are not indicative of the annual or quarterly revenues through the remainder of that fiscal year.

As an indication of this quarter-to-quarter seasonality, the Company generated approximately 75% of its 2020 revenues during the first and fourth quarters compared to 25% of 2020 revenues during the second and third quarters.

Direct Operating Expenses:

Direct operating expenses, which include labor costs, propane, fuel, chemicals, truck repairs and maintenance, supplies, insurance, and site overhead costs for our operating segments decreased by approximately $3.4 million or 40% during the first quarter of 2021 compared to the comparable period in 2020, primarily due to the severe reduction in revenue, discussed above.

Sales, General, and Administrative Expenses:

During the three months ended March 31, 2021, sales, general, and administrative expenses decreased approximately $757,000, or 43%, to $1.0 million compared to the same period in 2020 primarily due to a decrease in our bad debt expense and a decrease in professional fees related to our attempt to restructure our debt facility during the first quarter of 2020.

Depreciation and Amortization:

Depreciation and amortization expense for the three months ended March 31, 2021 decreased by $60,000, or 4%, compared to the same period in 2020 due primarily to the disposal of assets throughout 2020.

36

Income from operations:

For the three months ended March 31, 2021, the Company recognized a loss from operations of $2.4 million compared to a loss from operations of $2.3 million for the comparable period in 2020. The increased loss of $106,000 was primarily due to the decrease in segment profits described above. 

Interest Expense:

Interest expense decreased approximately $608,000, or 95%, for the three months ended March 31, 2021, compared to the same period in 2020. The decrease was primarily due to the cessation of recording interest expense after the troubled debt restructuring of our Credit Facility during the third quarter of 2020.

Discontinued Operations:

Results for the three months ended March 31, 2021 and 2020 include loss from discontinued operations of approximately $8,000 and income from discontinued operations of $36,000, respectively.

Other expense (income):

Other expense for the three months ended March 31, 2021 was approximately $78,000, compared to other income of approximately $20,000 for the three months ended March 31, 2020, respectively. This increase in other expense was due primarily to the recognition of the loss on the conversion of subordinated debt in the amount of the fair value of the warrant, partially offset by the CARES Act payroll tax credits during the first quarter of 2021. The Company expects the recognition of these CARES Act payroll tax credits to continue through the third quarter of 2021.

Income Taxes:

As discussed in the Explanatory Note above, during the three months ended March 31, 2021, the Company experienced a change in control pursuant to the issuance of 4,199,998 shares of common stock. As a result of this change in control, and in accordance with Internal Revenue Service Code Section 382, the realizability of the Company's deferred tax assets became limited. Based on management's judgment, the Company estimates that as of March 31, 2021, $1.4 million of deferred tax liabilities could reverse without an offsetting deferred tax asset. Due to this, the Company has recognized $1.4 million of deferred income tax expense for the three months ended March 31, 2021. For the three months ended March 31, 2020, the Company's income tax benefit of $0.7 million was adjusted by the valuation allowance which resulted in a net tax provision of zero.

The effective tax expense for the three months ended March 31, 2021 and 2020 differs from the amount that would be provided by applying the statutory U.S. federal income tax rate of 21% to pre-tax income primarily because of state income taxes, estimated permanent differences and the recorded valuation allowance.

Adjusted EBITDA (Restated)*

Management believes that, for the reasons set forth below, Adjusted EBITDA (a non-GAAP measure) is a valuable measurement of the Company's liquidity and performance and is consistent with the measurements offered by other companies in Enservco's industry.

The following table presents a reconciliation of our net loss to our Adjusted EBITDA for each of the periods indicated (in thousands):

	Three Months Ended March 31,
	2021			2021			2021			2020

Adjusted EBITDA*	$	(940	)	$	-		$	(940	)	$	(503	)

*Note: See below for discussion of the use of non-GAAP financial measurements.

Use of Non-GAAP Financial Measures: Non-GAAP results are presented only as a supplement to the financial statements and for use within management’s discussion and analysis based on U.S. generally accepted accounting principles (GAAP). The non-GAAP financial information is provided to enhance the reader's understanding of the Company’s financial performance, but no non-GAAP measure should be considered in isolation or as a substitute for financial measures calculated in accordance with GAAP. Reconciliations of the most directly comparable GAAP measures to non-GAAP measures are provided herein.

EBITDA is defined as net (loss) income, before interest expense, income taxes, and depreciation and amortization. Adjusted EBITDA excludes stock-based compensation from EBITDA and, when appropriate, other items that management does not utilize in assessing the Company’s ongoing operating performance as set forth in the next paragraph. None of these non-GAAP financial measures are recognized terms under GAAP and do not purport to be an alternative to net income as an indicator of operating performance or any other GAAP measure.

All of the items included in the reconciliation from net income to EBITDA and from EBITDA to Adjusted EBITDA are either (i) non-cash items (e.g., depreciation, amortization of purchased intangibles, stock-based compensation, impairment losses, etc.) or (ii) items that management does not consider to be useful in assessing the Company’s ongoing operating performance (e.g., income taxes, gain or losses on sale of equipment, severance and transition costs, other expense (income), EBITDA related to discontinued operations, etc.). In the case of the non-cash items, management believes that investors can better assess the company’s operating performance if the measures are presented without such items because, unlike cash expenses, these adjustments do not affect the Company’s ability to generate free cash flow or invest in its business.

We use, and we believe investors benefit from the presentation of, EBITDA and Adjusted EBITDA in evaluating our operating performance because it provides us and our investors with an additional tool to compare our operating performance on a consistent basis by removing the impact of certain items that management believes do not directly reflect our core operations. We believe that EBITDA is useful to investors and other external users of our financial statements in evaluating our operating performance because EBITDA is widely used by investors to measure a company’s operating performance without regard to items such as interest expense, taxes, and depreciation and amortization, 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. Additionally, our fixed charge coverage ratio covenant associated with our Loan and Security Agreement with East West Bank require the use of Adjusted EBITDA in specific calculations.

38

Because not all companies use identical calculations, the Company’s presentation of non-GAAP financial measures may not be comparable to other similarly titled measures of other companies. However, these measures can still be useful in evaluating the Company’s performance against its peer companies because management believes the measures provide users with valuable insight into key components of GAAP financial disclosures.

Changes in Adjusted EBITDA*

Adjusted EBITDA for the three months ended March 31, 2021 decreased by approximately $437,000 due primarily to the decrease in outside professional services incurred during the first quarter of 2020 related to our attempt to restructure our Credit Facility, as well as the increase in the CARES Act payroll tax credits recognized during the first quarter of 2021.

LIQUIDITY AND CAPITAL RESOURCES 

As of March 31, 2021, we had an outstanding principal loan balance under the amended Credit Facility of approximately $14.0 million with a weighted average interest rate of 8.25% per year. 

The following table summarizes our statements of cash flows for the three months ended March 31, 2021 and 2020 (in thousands):

Stockholders’ Equity		9,386		2,555

 Overview:

We have accomplished several capitalization initiatives in the past year that have positioned us into a much more favorable liquidity situation. We successfully completed two equity offerings during late 2020 and early 2021 that provided aggregate net proceeds of $12.3 million. Additionally, we entered into two amendments to our Credit Facility during the third quarter of 2020 and the first quarter of 2021 that provided us with significant relief under our Credit Facility, including a $16.0 million principal reduction, and two extensions of the debt which now matures on October 15, 2022. Upon closing on our second equity offering on February 11, 2021, we made a $3.0 million principal payment on our Credit Facility.

We have relied on cash flow from operations and borrowings under the $1.0 million line of credit under our Credit Facility to satisfy our liquidity needs. Due to the funding from the two equity offerings and the restructuring and further extension of the Credit Facility, we have ample capital resources to fund operational requirements beyond the next twelve months. At March 31, 2021, in addition to cash of $3.7 million, we had $1.0 million available under the Credit Facility. Our capital requirements for the remainder of 2021 are anticipated to include, but are not limited to, operating expenses, debt servicing, and capital expenditures, including maintenance of our existing fleet of assets. Under our Amended 2017 Credit Agreement, we are restricted to capital expenditures of $1.2 million during 2021.

40

Liquidity:

As of March 31, 2021, our available liquidity was $4.7 million which represented our cash balance of $3.7 million and $1.0 million availability on the line of credit under our 2017 Credit Facility. We utilize the line of credit under our 2017 Credit Facility to fund working capital requirements and investments, and during the three months ended March 31, 2021, we repaid net cash borrowings from our line of credit of approximately $701,000. 

Working Capital:

As of March 31, 2021, we had working capital of approximately $5.0 million, compared to working capital of $306,000 as of December 31, 2020. The $4.7 million increase in working capital was primarily attributable to the closing of our February 2021 Public Offering which provided net proceeds of approximately $8.8 million, partially offset by the $3.0 principal paydown of our long-term Credit Facility.

41

Cash flow from Operating Activities:

For the three months ended March 31, 2021, cash used in operating activities was approximately $2.6 million compared to $969,000 during the comparable period in 2020. The increase in cash used was attributable to the decrease in cash provided by the monetization of accounts receivable and an increase in the cash used for prepaid expenses and other current assets during the current year period, partially offset by the decrease in net loss and the increase in cash flows related to the change in accounts payable balances.

Cash flow from Investing Activities:

Cash used in investing activities during the three months ended March 31, 2021 was approximately $32,000, compared to cash provided by $14,000 during the comparable period in 2020, primarily due to proceeds received from the sale of equipment related to our discontinued operations during the prior year period, partially offset by the decrease in capital expenditures during the current year period.

Cash flow from Financing Activities:

Cash provided by financing activities for the three months ended March 31, 2021 was approximately $4.9 million, compared to $509,000 for the comparable period in 2020. The change is due to the net proceeds from our February 2021 Public Offering, partially offset by line of credit repayments and the paydown of our long-term Credit Facility during the first quarter of 2021.

Outlook: 

Over the past three years we have invested significantly in process improvement initiatives designed to make the Company operate more efficiently and take better advantage of our expanded fleet and national leadership position in frac water heating. We face a very difficult operating environment in 2021 with exploration and production companies significantly cutting back their drilling and completions plans and exerting significant pressure on us to reduce our prices for the services we provide. In order to position us in a more sustainable liquidity situation, we successfully completed two equity offerings during late 2020 and early 2021 that provided us with aggregate net proceeds of $12.3 million. Additionally, we entered into two amendments to our Credit Facility during the in late third quarter 2020 and the first quarter of 2021 that provided us with significant relief under our Credit Facility, including a $16.0 million principal reduction, and two extensions of the debt which now matures on October 15, 2022. Upon closing on our second equity offering, which occurred on February 11, 2021, we made a $3.0 million principal payment on our Credit Facility. Our business is heavily dependent on exploration and production activity levels, which fluctuate based on commodity prices, capital budgets and other factors. Activity levels significantly declined throughout 2020 due to the depression of commodity prices, the decrease in active rigs and the impacts of the COVID-19 pandemic. The economic impacts of the pandemic and the significantly lower rig counts have continued into 2021. We continue to seek opportunities to expand our business operations through organic growth, including increasing the volume of current services offered to our new and existing customers and relocating more of our equipment to increase utilization. We will also continue to expand our customer relationships while maintaining an appropriate balance between recurring maintenance work and drilling and completion related services.

Capital Commitments and Obligations:

Our capital obligations as of March 31, 2021 consist primarily the 2017 Credit Agreement which matures October 15, 2022. In addition, we also have scheduled principal payments under certain term loans, finance leases and operating leases. General terms and conditions for amounts due under these commitments and obligations are summarized in the notes to the financial statements.

42

OFF-BALANCE SHEET ARRANGEMENTS

As of March 31, 2021, we had no significant off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to our stockholders.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES 

There have been no changes in our critical accounting policies since December 31, 2020. 

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are a smaller reporting company as defined in Rule 12b-2 of the Exchange Act and are not required to provide the information under this Item.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) or 15d-15(e) promulgated under the Exchange Act, as of March 31, 2021. This evaluation was carried out under the supervision and with the participation of our Chief Executive Officer (our principal executive officer) and our Chief Financial Officer (our principal financial officer). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, due to the material weakness in our internal control over financial reporting described below, as of the Evaluation Date, our disclosure controls and procedures were not effective to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms.

A material weakness is a deficiency, or a combination of 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 and corrected on a timely basis. In connection with the preparation of Amendment No. 1, management previously re-evaluated the Company’s application of the accounting for a warrant issued to a related party in connection with a conversion of subordinated debt to equity during the first quarter of 2021. Upon such re-evaluation, management determined that the award of the warrant resulted in a loss on the transaction with a related party, as discussed in Note 2 to our unaudited condensed consolidated financial statements in Amendment No. 1. As discussed in the Explanatory Note above, in connection with the preparation of this Amendment No. 2, the Company has re-evaluated its accounting for income taxes in connection with a change in control that occurred pursuant to the issuance of 4,199,998 shares of common stock during the first quarter of 2021. This change in control led to a change in management's judgment about the realizability of the Company's deferred tax assets. Pursuant to such re-evaluation, the Company’s management has determined that for the three months ended March 31, 2021 the Company should have recognized deferred income tax expense through the recording of additional valuation allowance, as discussed in Note 2 to our unaudited condensed consolidated financial statements in this Amendment No. 2.

As a result, our management concluded that there was a material weakness in our internal control over financial reporting as of March 31, 2021 related to our accounting for complex financial instruments and our accounting for income taxes.

Changes in Internal Control over Financial Reporting

There has been no change in the Company's internal control over financial reporting, as such term is defined under Rule 13a-15(f) of the Exchange Act, during the quarter covered by this report that has materially affected, or is reasonably likely to materially affect, its internal control over financial reporting as the circumstances that led our management to conclude that our previously issued financial statements should be restated had not yet been identified.

In light of the material weakness described above, we plan to continue to enhance our system of evaluating and implementing the accounting standards that apply to our accounting for complex financial instruments and certain tax positions, including through enhanced analyses by our personnel and third-party professionals with whom we consult regarding complex accounting and tax applications. We can offer no assurance that our remediation plan will ultimately have the intended effects.

Amendment Description	This Amendment No. 2 (“Amendment No. 2”) to the Quarterly Report on Form 10-Q/A amends the Quarterly Report on Form 10-Q of Enservco Corporation as of and for the quarter ended March 31, 2021, as filed with the Securities and Exchange Commission (“SEC”) on May 13, 2021 (the “Original Filing”), and as amended and filed with the SEC on April 11, 2022 ("Amendment No. 1"). The Company has re-evaluated its accounting for income taxes in connection with a change in control that occurred pursuant to the issuance of 4,199,998 shares of common stock during the first quarter of 2021. This change in control led to a change in management's judgment about the realizability of the Company's deferred tax assets. Pursuant to such re-evaluation, the Company's management has determined that for the three months ended March 31, 2021 the Company should have recognized deferred income tax expense through the recording of additional valuation allowance. Therefore, on April 14, 2022, the Company's management and the audit committee of the Company's board of directors concluded that the Company's unaudited interim financial statements included in the Original Filing, as amended by Amendment No. 1, should be restated to recognize the deferred tax liability associated with this limitation. As such, the Company is filing this Amendment No. 2 to affect such restatement. The restatement has no impact on the Company's cash position, revenues, operating expenses, loss from operations or Adjusted EBITDA as of and for the three months ended March 31, 2021. We are filing this Amendment No. 2 to amend and restate the Original Filing, as previously amended by Amendment No. 1, with modification as necessary to reflect the restatement. The following items have been amended to reflect the restatement: (i) Part I, Item 1. Financial Statements; and (ii) Part I, Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations. In addition, the Company's Principal Executive Officer and Interim Principal Financial Officer has provided new certifications dated as of the date of this filing in connection with this Form 10-Q/A (Exhibits 31.1 and 32). As a result of the factors described above, the Company's management has concluded that a material weakness existed in the Company's internal control over financial reporting and that the Company's disclosure controls and procedures were not effective. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the financial statements will not be prevented or detected and corrected on a timely basis. For a discussion of management's consideration of the material weakness identified, see Part I, Item 4. Controls and Procedures included in this Amendment No. 2. Except as described above, no other information included in the Original Filing, as amended by Amendment No. 1, is being amended or updated by this Amendment No. 2. This Amendment No. 2 continues to describe the conditions as of the date of the Original Filing. Except as expressly contained herein, we have not updated, modified or supplemented the disclosures contained in the Original Filing or Amendment No. 1, and this Amendment No. 2 does not purport to reflect any information or events subsequent to the date of the Original Filing. Accordingly, this Amendment No. 2 should be read in conjunction with the Original Filing, Amendment No. 1 and with our filings with the SEC subsequent to the Original Filing

additional shares of Company common stock in the future, as well as further extending the maturity date for the repayment of the Credit Facility to

October 15, 2021.

On

February 1, 2021,

we entered into the Sixth Amendment to Loan and Security Agreement (the "Sixth Amendment") which extended the maturity date of the loan for an additional year to

October 15, 2022, 

and modified certain covenants. On

April 26, 2021,

we entered into the Seventh Amendment to Loan and Security Agreement (the "Seventh Amendment") which provided for amortization of the loan on a

10

-year straight-line basis commencing on

November 15, 2021.

As the terms of the Seventh Amendment were contemplated prior to

March 31, 2021,

the principal payments due over the next

twelve

months have been classified as current on the consolidated balance sheets as of

March 31, 2021.

On

August 13, 2020,

the Company's Board of Directors approved a transaction to exchange 

50%,

or

$1.25

million, of our subordinated debt with Cross River Partners, L.P., a related party, as well as

$265,000

in accrued interest, for

403,602

shares of Company common stock. This transaction was finalized on

September 15, 2020. 

On

February 3, 2021,

Cross River Partners, L.P. converted the remaining principal amount of such subordinated debt, or

$1.25

million, as well as

$62,000

in accrued interest, for

601,674

shares of Company common stock, at a conversion price equal to

$2.18

per share, which was the closing price of the Company's stock reported on the NYSE American on the date of the conversion. In connection with such conversion, the Company issued a warrant to Cross River Partners, L.P. to purchase up to

150,418

additional shares of Company common stock in the future at an exercise price of

$2.507

per share. The warrant for the

150,418

shares has a

five

-year term and is exercisable beginning

February 3, 2022

until

February 3, 2026.

The issuance of the warrant at its grant date fair value of

$2.02

per share caused the Company to record a loss of approximately

$304,000

upon the conversion of the subordinated debt in the

first

quarter of

2021.

On

September 28, 2020,

the Company filed a final prospectus to its registration statement on Form S-

3

(the "Shelf Registration Statement") that was filed with the Securities and Exchange Commission (the "SEC") on

July 24, 2020,

and declared effective on

August 20, 2020. 

On

September 29, 2020,

pursuant to the Shelf Registration Statement, the Company, through its sales agent Alliance Global Partners ("AGP"), commenced an at-the-market offering (the "ATM Offering") which was designed to raise capital by issuing securities into the trading market, over-time, at the then-market price of the securities at the time they are sold. The Company sold

1,694,219

shares of Company common stock in the ATM Offering and collected net proceeds of

$3.5

million.

On

February 8, 2021,

the Company entered into an Underwriting Agreement with AGP for a firm commitment underwritten public offering of the Company's common stock pursuant to a registration statement on Form S-

1

originally filed with the SEC on

January 21, 2021

and declared effective on

February 8, 2021 (

the

"February 2021

Public Offering"). Pursuant to the Underwriting Agreement, the Company issued and sold

4,199,998

shares of Company common stock, including shares issued and sold pursuant to AGP's over-allotment option, at a public offering price of

$2.30

per share. The Company collected net proceeds of

$8.8

million in the

February 2021

Public Offering, which closed on

February 10, 2021.

The Company made a

$3.0

million principal payment on the Credit Facility upon the closing of the

February 2021

Public Offering.

Recent Market Conditions

The COVID-

19

pandemic has significantly impacted the world economic conditions including in the United States, with significant effects beginning in

February 2020,

and continuing through the issuance of this report, as federal, state and local governments react to the public health crisis, creating significant uncertainties relating to the United States economy. Consequently, the Company has experienced and expects to further experience a material adverse impact on its revenues, results of operations and cash flows. COVID-

19

related quarantines and business restrictions have had a depressing impact on United States oil demand, and hence our business, which continues through the filing date of this report. The situation continues to change rapidly and additional impacts to our business

may

arise that we are

not

aware of currently. We cannot predict whether, when or the manner in which the conditions surrounding COVID-

19

will change including the timing of lifting any restrictions or office closure requirements.

In addition, certain producing countries within the Organization of Petroleum Exporting Countries and their allies ("OPEC+") group attempted to increase market share through pricing activity that has had limited impact on the severe decline in domestic oil prices that occurred during the

first

quarter of

2020,

and drilling and operating activity within our markets has remained depressed. There is

no

assurance that such efforts will

not

re-occur in the future.

The full extent of the impact of COVID-

19

and OPEC+ actions on our operations and financial performance depends on future developments that are uncertain and unpredictable, including the duration and spread of the pandemic, its impact on capital and financial markets, any new information that

may

emerge concerning the severity of the virus, its spread to other regions as well as the actions taken to contain it, production response of domestic oil producers to lower oil prices, and the adherence to and continuity of OPEC+ production cuts, among others.

Cash and Cash Equivalents

The Company considers all highly liquid instruments purchased with an original maturity of

three

months or less to be cash equivalents. The Company continually monitors its positions with, and the credit quality of, the financial institutions with which it invests. Enservco maintains its excess cash in various financial institutions, where deposits

may

exceed federally insured amounts at times. 

Accounts Receivable

Accounts receivable are stated at the amounts billed to customers, net of an allowance for uncollectible accounts. The Company provides an allowance for uncollectible accounts based on a review of outstanding receivables, historical collection information and existing economic conditions. The allowance for uncollectible amounts is continually reviewed and adjusted to maintain the allowance at a level considered adequate to cover future losses. The allowance is management's best estimate of uncollectible amounts and is determined based on historical collection experience related to accounts receivable coupled with a review of the current status of existing receivables. The losses ultimately incurred could differ materially in the near term from the amounts estimated in determining the allowance. As of

March 31, 2021, 

and

December 31, 2020,

the Company had an allowance for doubtful accounts of approxim

ately

$359,000

 and

$322,000,

respectively. For t

he

three

 months ended

March 31, 2021

and 

2020,

the Compan

y recorded approximately

$38,000

 and

$300,000

 to bad debt expense, respectively.

Inventories

Inventory consists primarily of propane, diesel fuel and chemicals that are used in the servicing of oil wells and is carried at the lower of cost or net realizable value in accordance with the

first

in,

first

out method (FIFO). The Company periodically reviews the value of items in inventory and provides write-downs or write-offs, of inventory based on its assessment of market conditions. Write-downs and write-offs are charged to cost of goods sold. For the

three

 months ended March

31

,

2021

and

2020,

the Compan

y did

not

recognize any

write-downs or write-offs of inventory

.

Property and Equipment

Property and equipment consist of (i) trucks, trailers and pickups; (ii)

water transfer pumps, pipe, lay flat hose, trailers, and other support equipment;

(iii) real property which includes land and buildings used for office and shop facilities and wells used for the disposal of water; (iv) other equipment such as tools used for maintaining and repairing vehicles, and (v) office furniture and fixtures, and computer equipment. Property and equipment is stated at cost less accumulated depreciation. The Company capitalizes interest on certain qualifying assets that are undergoing activities to prepare them for their intended use. Interest costs incurred during the fabrication period are capitalized and amortized over the life of the assets. The Company did

not

capitalize any interest during the

three

months ended

March 31, 2021

or

2020.

 The Company charges repairs and maintenance against income when incurred and capitalizes renewals and betterments, which extend the remaining useful life, expand the capacity or efficiency of the assets. Depreciation is recorded on a straight-line basis over estimated useful lives of

5

to

30

years.

Any difference between net book value of the property and equipment and the proceeds of an assets' sale or settlement of an insurance claim is recorded as a gain or loss in the Company's earnings.

Leases

The Company assesses whether an arrangement is a lease at inception. Leases with an initial term of

12

months or less are

not

recorded on the balance sheet. We have elected the practical expedient to

not

separate lease and non-lease components for all assets. Operating lease assets and operating lease liabilities are calculated based on the present value of the future minimum lease payments over the lease term at the lease start date. As most of our leases do

not

provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease start date in determining the present value of future payments. The operating lease asset is increased by any lease payments made at or before the lease start date and reduced by lease incentives and initial direct costs incurred. The lease term includes options to renew or terminate the lease when it is reasonably certain that we will exercise that option. The exercise of lease renewal options is at our sole discretion. The depreciable life of lease assets and leasehold improvements are limited by the lease term. Lease expense for operating leases is recognized on a straight-line basis over the lease term.

The Company conducts a major part of its operations from leased facilities. Each of these leases is accounted for as an operating lease. Operating lease assets and liabilities are recognized at the lease commencement date. Operating lease liabilities represent the present value of lease payments

not

yet paid. Operating lease assets represent our right to use an underlying asset and are based upon the operating lease liabilities adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of operating lease assets.

The Company amortizes leasehold improvements over the shorter of the life of the lease or the life of the improvements. 

The Company has leased trucks and equipment in the normal course of business, which

may

be recorded as operating or finance leases, depending on the term of the lease. The Company recorded 

rental expense on equipment under operating leases over the lease term as it becomes payable; there were

no

 

rent escalation terms associated with these equipment leases. The Company records amortization expense on equipment under finance leases on a straight-line basis as well as interest expense based on our implicit borrowing rate at the date of the lease inception. The equipment leases contain purchase options that allow the Company to purchase the leased equipment at the end of the lease term, based on the market price of the equipment at the time of the lease termination. 

Long-Lived Assets

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset

may

not

be recovered. During the

first

quarter of

2021,

the Company concluded that there were

no

further triggering events which could indicate impairment of its long-lived assets. During the

first

quarter of

2020,

the combination of the COVID-

19

pandemic and actions taken by the OPEC+ countries caused oil and gas commodity demand to decrease significantly. The Company determined that these were triggering events which could indicate impairment of its long-lived assets. The Company reviewed both qualitative and quantitative aspects of the business during the analysis of impairment. During the quantitative review, the Company reviews the undiscounted future cash flows in its assessment of whether long-lived assets have been impaired. The Company determined that there was

no

impairment of its long-lived assets during the 

three

months ended March

31,

2021.

Assets Held for Sale

The Company classifies long-lived assets to be sold as held for sale in the period in which all of the following criteria are met: (

1

) management, having the authority to approve the action, commits to a plan to sell the asset or disposal group; (

2

) the asset or disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets; (

3

) an active program to locate a buyer and other actions required to complete the plan to sell the asset or disposal group have been initiated; (

4

) the sale of the asset or disposal group is probable, and transfer of the asset or disposal group is expected to qualify for recognition as a completed sale within

one

year, except if events or circumstances beyond our control extend the period of time required to sell the asset or disposal group beyond

one

year; (

5

) the asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (

6

) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.

We initially measure a long-lived asset or disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held-for-sale criteria are met. Conversely, gains are

not

recognized on the sale of a long-lived asset or disposal group until the date of sale. We assess the fair value of a long-lived asset or disposal group less any costs to sell each reporting period it remains classified as held for sale and report any subsequent changes as an adjustment to the carrying value of the asset or disposal group, as long as the new carrying value does

not

exceed the carrying value of the asset at the time it was initially classified as held for sale. During the years

three

months ended

March 

31,

2021

 and

2020,

the Company recorded

no

impairment charges on its held for sale assets.

Upon determining that a long-lived asset or disposal group meets the criteria to be classified as held for sale, the Company ceases depreciation and reports long-lived assets and/or the assets and liabilities of the disposal group, if material, in the line items assets held for sale in our consolidated balance sheets.

Goodwill and Other Intangible Assets

Goodwill represents the excess purchase price over the fair value of identifiable assets received attributable to business acquisitions and combinations. Goodwill and other intangible assets are measured for impairment at least annually and/or whenever events and circumstances arise that indicate impairment

may

exist, such as a significant adverse change in the business climate. In assessing the value of goodwill, assets and liabilities are assigned to the reporting units and the appropriate valuation methodologies are used to determine fair value at the reporting unit level. Identified intangible assets are amortized using the straight-line method over their estimated useful lives.

During the

first

quarter of

2021,

the Company concluded that there were

no

further triggering events which could indicate impairment of its goodwill and other intangible assets. During the

first

quarter of

2020,

the combination of the COVID-

19

pandemic and actions taken by the OPEC+ countries caused oil and gas commodity demand to decrease significantly. The Company determined that these were triggering events which could indicate impairment of its goodwill and other intangible assets. The Company reviewed both qualitative and quantitative aspects of the business during the analysis of impairment. During the quantitative review, the Company uses both the fair value and discounted future cash flows in its assessment of whether goodwill and other intangible assets have been impaired. The Company determined that there was

no

impairment of its goodwill and other intangible assets during the 

three

months ended

March 31, 2020.

Revenue Recognition 

The Company evaluates revenue when we can identify the contract with the customer, the performance obligations in the contract, the transaction price, and we are certain that the performance obligations have been met. Revenue is recognized when the service has been provided to the customer. The vast majority of the Company's services and product offerings are short-term in nature. The time between invoicing and when payment is due under these arrangements is generally

30

to

60

days. Revenue is

not

generated from contractual arrangements that include multiple performance obligations.

The Company's agreements with its customers are often referred to as “price sheets” and sometimes provide pricing for multiple services. However, these agreements generally do

not

authorize the performance of specific services or provide for guaranteed throughput amounts. As customers are free to choose which services, if any, to use based on the Company's price sheet, the Company prices its separate services on the basis of their standalone selling prices. Customer agreements generally do

not

provide for performance, cancellation, termination, or refund type provisions. Services based on price sheets with customers are generally performed under separately issued “work orders” or “field tickets” as services are requested.

Revenue is recognized for certain projects that take more than

one

day projects over time based on the number of days during the reporting period and the agreed upon price as work progresses on each project.

Disaggregation of revenue

See Note

12

 - Segment Reporting for disaggregation of revenue.

Earnings (Loss) Per Share 

Earnings per Common Share - Basic is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Earnings per Common Share - Diluted earnings is calculated by dividing net income (loss) by the diluted weighted average number of common shares. The diluted weighted average number of common shares is computed using the treasury stock method for common stock that

may

be issued for outstanding stock options, restricted stock and warrants.

As of

March 

31, 2021 and 2020

, there were outstanding stock options, unvested restricted stock awards and warrants to acquire an aggregate

of

1,383,489

 and

247,048

 shares of Company common stock, respectively, which have a potentially dilutive impact on earnings per share. As of

March 

31, 2021 and 2020,

the outstanding stock options and warrants had

no

aggregate intrinsic value

(the difference between the estimated fair value of the Company's common stock on

March 31

, 2021 and 2020,

and the exercise price, multiplied by the number of in-the-money instruments). Dilution is

not

permitted if there are net losses during the period. As such, the Company does

not

show diluted earnings per share for the

three

months ended

March 31, 2021 

and

2020.

Income Taxes

The Company recognizes deferred tax liabilities and assets based on the differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements that will result in taxable or deductible amounts in future years. 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 of a change in tax rates on deferred tax assets and liabilities will be recognized in income in the period that includes the enactment date. A deferred tax asset or liability that is

not

related to an asset or liability for financial reporting is classified according to the expected reversal date. The Company records a valuation allowance to reduce deferred tax assets to an amount that it believes is more likely than

not

expected to be realized.

The Company accounts for any uncertainty in income taxes by recognizing the tax benefit from an uncertain tax position only if, in the Company's opinion, it is more likely than

not

that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The Company measures the tax benefits recognized in the financial statements from such a position based on the largest benefit that has a greater than

50%

likelihood of being realized upon ultimate resolution. The application of income tax law is inherently complex. Laws and regulations in this area are voluminous and are often ambiguous.  As such, the Company is required to make many subjective assumptions and judgments regarding income tax exposures. Interpretations of and guidance surrounding income tax law and regulations change over time and

may

result in changes to the Company's subjective assumptions and judgments which can materially affect amounts recognized in the consolidated balance sheets and consolidated statements of income. The result of the reassessment of the Company's tax positions did

not

have an impact on the consolidated financial statements.

Interest and penalties associated with tax positions are recorded in the period assessed as Other expense. The Company files income tax returns in the United States and in the states in which it conducts its business operations. The Company

's United States federal income tax filings for tax years

2017

 through

2020

 remain open to examination. In general, the Company's various state tax filings remain open for tax years

2016

 to

2020.

Fair Value

The Company follows authoritative guidance that applies to all financial assets and liabilities required to be measured and reported on a fair value basis. The Company also applies the guidance to non-financial assets and liabilities measured at fair value on a nonrecurring basis, including non-competition agreements and goodwill. The guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date.  The guidance establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available.

Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions of what market participants would use in pricing the asset or liability based on the best information available in the circumstances.  Beginning in 

2017

the Company valued its warrants using the Binomial Lattice model ("Lattice"). Specific inputs used in the Lattice are the underlying stock price, the exercise price of the warrant, expected dividends, historical volatility, term to expiration and risk-free interest rates. The Company did

not

have any transfers between hierarchy levels during the

three

 months ended March 

31, 2021

. The financial and nonfinancial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement.

The hierarchy is broken down into

three

levels based on the reliability of the inputs as follows:

Level 1: Quoted prices are available in active markets for identical assets or liabilities;

Level 2: Quoted prices in active markets for similar assets and liabilities that are observable for the asset or liability; or

Level 3: Unobservable pricing inputs that are generally less observable from objective sources, such as discounted cash flow models or valuations.

Stock-based Compensation

Stock-based compensation cost is measured at the date of grant, based on the calculated fair value of the award as described below, and is recognized over the requisite service period, which is generally the vesting period of the equity grant.

The Company uses the Black-Scholes pricing model as a method for determining the estimated grant date fair value for all stock options awarded to employees, independent contractors, officers, and directors. The expected term of the options is based upon evaluation of historical and expected exercise behavior. The risk-free interest rate is based upon U.S. Treasury rates at the date of grant with maturity dates approximately equal to the expected life of the grant. Volatility is determined upon historical volatility of our stock and adjusted if future volatility is expected to vary from historical experience. The dividend yield is assumed to be

none

as we have

not

paid dividends, nor do we anticipate paying any dividends in the foreseeable future.

The Company

 uses a Lattice model to determine the fair value of certain warrants. The expected term used was the remaining contractual term. Expected volatility is based upon historical volatility over a term consistent with the remaining term. The risk-free interest rate is derived from the yield on

zero

-coupon U.S. government securities with a remaining term equal to the contractual term of the warrants. The dividend yield is assumed to be zero.

The Company used the market-value of Company stock to determine the fair value of the performance-based restricted stock awarded in

2018

and

2019.

Stock based compensation is updated quarterly based on actual forfeitures. The Company used either a Lattice model or the Black-Scholes pricing model to determine the fair value of market-based restricted stock awarded in

2021

 and

2020.

Management Estimates

The preparation of the Company's consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include the realization of accounts receivable, evaluation of impairment of long-lived assets, stock-based compensation expense, income tax provision and the valuation of deferred taxes. Actual results could differ from those estimates.

Reclassifications

Certain prior-period amounts have been reclassified for comparative purposes to conform to the current

 presentation. These reclassifications have

no

effect on the Company's consolidated statement of operations.

East West Bank

Revolving

Credit Facility

The 

2017

 Credit Agreement (as defined in Note

3

) originally allowed us to borrow up to 

85%

 of our eligible receivables and up to 

85%

 of the appraised value of our eligible equipment. The Fifth Amendment restructured the loan and provided for a loan forgiveness of

$16.0

million and converts the remaining principal balance to a

$17.0

million equipment term loan and a revolver to provide the Company with a maximum

$1.0

million line of credit. The Sixth Amendment further extended the maturity date and modified the financial covenants effective

January 1, 2021. 

There are 

no

 required principal payments until maturity on

October 15, 2022, 

and interest is fixed at

8.25%.

 Interest on the

first

5.25%

 is calculated monthly and paid in arrears, while the remaining

3.00%

is accrued to the loan balance through

October 15, 2021,

and due with all remaining outstanding principal on the maturity date. Additionally, the Credit Facility is subject to an unused credit line fee of 

0.5%

 per annum multiplied by the amount by which total availability exceeds the average monthly balance of the Credit Facility, payable monthly in arrears. The Credit Facility is collateralized by substantially all our assets and subject to financial covenants.

On

February 11, 2021,

the Company made a

$3.0

million payment of principal on the equipment term loan. As of

March 31, 2021,

we had an outstanding principal loan balance under the Credit Facility of approximately

$15.2

million with a weighted average interest rates of

8.25%

per year. As of

March 31, 2021,

our availability under the amended

2017

Credit Agreement was 

$1.0

million. The Credit Facility balance of

$15.2

million at

March 31, 2021 

includes 

$1.2

million of future interest payable due over the remaining term of the Credit Facility in accordance with ASC

Troubled Debt Restructuring by Debtors.

Under the amended 

2017

Credit Agreement, we are subject to the following financial covenants, with which we were in compliance as of March

31,

2021:

(

1

) 

On

December 31, 2020,

we were required to maintain liquidity of

not

less than

$1.5

million; and

(

2

) 

For each trailing

three

-month period, commencing with the

three

-month period ending

March 31, 2021,

we are required to achieve gross revenue of at least

seventy

percent (

70%

) of our projected gross revenue; and

(

3

) We are limited to a capital expenditures cap of

$1.2

million for any fiscal year that the loan remains outstanding.

In connection with amending the

2017

Credit Agreement on

September 23, 2020, 

the Company issued to East West Bank

533,334

shares of Company common stock, and a

five

-year warrant to purchase up to

1,000,000

additional shares of Company common stock at an exercise price of

$3.75

per share. The

533,334

shares of Company common stock were valued at a price of

$2.0775

per share, or a total value of

$1.1

million. The

533,334

common shares issued to East West Bank could

not

be sold or transferred prior to

March 23, 2021. 

The warrant for

1,000,000

shares is exercisable beginning

September 23, 2021

until

September 23, 2025.

The fair value of the warrant was determined to be

$1.4

million and were recorded in additional paid-in capital. The Company recorded a total gain on the debt restructuring of

$11.9

million during the

third

quarter of

2020,

which was calculated by subtracting from the

$16.0

million loan forgiveness, a) the future interest payable on the Credit Facility; b) the value of the Company common stock issued; and c) the fair value of the warrant.

Debt Issuance Costs

We capitalized certain debt issuance costs incurred in connection with the Credit Facility discussed above and these costs were amortized to interest expense over the term of the facility

 on a straight-line basis. There were

no

remaining unamortized debt issuance costs as of

 March 31, 2021,

Note 8 - Income Taxes

Income Tax Disclosure [Text Block]

Note

8

 – Income Taxes 

Income tax expense during interim periods is based on applying an estimated annual effective income tax rate to year-to-date income, plus any significant unusual or infrequently occurring items which are recorded in the interim period.  The provision for income taxes for the

three

months ended

March 

31, 2021

and

2020

differs from the amount that would be provided by applying the statutory U.S. federal income tax rate of

21

% to pre-tax income primarily because of state income taxes and estimated permanent differences.

The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including, but

not

limited to, the expected operating income for the year, projections of the proportion of income earned and taxed in various jurisdictions, permanent and temporary differences, and the likelihood of recovering deferred tax assets generated in the current year.  The accounting estimates used to compute the provision for income taxes

may

change as new events occur, more experience is obtained, additional information becomes known or as the tax environment changes.

In assessing the realization of deferred tax assets, management considers whether it is more likely than 

not

 that some portion or all of the deferred tax assets will 

not

 be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment.

As discussed in the Explanatory Note above, during the

three

months ended

March 31, 2021,

the Company experienced a change in control pursuant to the issuance of

4,199,998

shares of common stock. As a result of this change in control, and in accordance with Internal Revenue Service Code Section

382,

the realizability of the Company's deferred tax assets became limited. Based on management's judgment, the Company estimates that as of

March 31, 2021,

$1.4

million of deferred tax liabilities could reverse without an offsetting deferred tax asset. Due to this, the Company has recognized

$1.4

million of deferred income tax expense for the

three

months ended

March 31, 2021.

For the

three

months ended

March 31, 

2020,

the Company's income tax benefit of

$0.7

 million was adjusted by the valuation allowance which resulted in a net tax provision of zero.

 – Commitments and Contingencies 

Operating Leases

Operating lease assets and liabilities are recognized at the lease commencement date. Operating lease liabilities represent the present value of lease payments

not

yet paid. Operating lease assets represent our right to use an underlying asset and are based upon the operating lease liabilities adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of operating lease assets. To determine the present value of lease payments

not

yet paid, the Company uses the weighted average interest rate on its Credit Facility. Long-term leases typically contain rent escalations over the lease term. The Company recognizes expense for these leases on a straight-line basis over the lease term.

The Company has elected the short-term lease recognition exemption for all applicable classes of underlying assets. Short-term disclosures include only those leases with a term greater than

one

month and

12

months or less, and expense is recognized on a straight-line basis over the lease term. Leases with an initial term of

12

months or less, that do

not

include an option to purchase the underlying asset that we are reasonably certain to exercise, are

not

recorded on the balance sheet.

The Company elected the expedient to account for lease and non-lease components as a single component for our entire population of operating lease assets.

As of

March

the Company leases facilities and certain equipment under lease commitments that expire throu

Self-Insurance

In

June 2015,

the Company became self-insured under its Employee Group Medical Plan, and currently is responsible to pay the

first

 

$50,000

in medical costs per indiv

idual participant for claims incurred in the calendar year up to a maximum of approximately

$1.8

million per year in the aggregate based on enrollment.

The Company had an accrued liability of approximately $

108,000

 

and

$150,000

 as of

March 

31, 2021

and

December 31, 2020,

respectively, for insurance claims that it anticipates paying in the future related to claims that occurred prior

to

December 31, 2020. 

Effective

January 1, 2021,

the Company moved onto a traditional Employee Group Medical Plan and was

no

longer self-insured for claims occurring after that date.

Effective

April 1, 2015,

the Company had entered into a workers' compensation and employer's liability insurance policy with a term through

March 31, 2018. 

Under the terms of the policy, the Company was required to pay premiums in addition to a portion of the cost of any claims made by our employees, up to a maximum of approximately

$1.8

million over the term of the policy (an amount that was variable with changes in annualized compensation amounts). As of

March 31, 2021,

a former employee of ours had an open claim relating to injuries sustained while in the course of employment, and the projected maximum cost of the policy as determined by the insurance carrier included estimated claim costs that have

not

yet been paid or incurred in connection with the claim. During the year ended

December 31, 2017,

our insurance carrier formally denied the workers' compensation claim and has moved to close the claim entirely. Per the terms of our insurance policy, through

March 31, 2021,

we had paid in approximately

$1.8

million of the projected maximum plan cost of

$1.8

million, and had recorded approximately

$1.6

 million as expense over the term of the policy. In

September 2020,

the claim was officially denied by the Kansas Division of Workers Compensation Judicial Unit. As of

March 31, 2021,

no

appeal has been made and the Company expects to collect the remaining

$189,000

on deposit with the underwriter. Effective 

April 1, 2018,

we entered into a new workers' compensation policy with a fixed premium amount determined annually, and therefore are

no

longer partially self-insured for workers' compensation and employer's liability.

On

April 12, 2021,

the SEC issued a Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies ("SPACs")(the "Staff Statement"). The SEC highlighted accounting considerations which could, in certain circumstances, indicate that warrants should be accounted for as liabilities rather than equity instruments, in which case the warrants would be subject to fair value adjustments during each reporting period. Although the Staff Statement focused on SPACs, the same accounting considerations

may

apply to warrants issued by non-SPAC entities. Upon issuance of the Staff Statement, the Company performed further analysis on its population of warrants, which are listed above, giving consideration to the areas of concern noted in the Staff Statement. Upon this further review of its warrant agreements, the Company determined that it has correctly accounted for its warrants as equity instruments.

Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2021

Accounting Policies [Abstract]

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

The Company considers all highly liquid instruments purchased with an original maturity of

three

months or less to be cash equivalents. The Company continually monitors its positions with, and the credit quality of, the financial institutions with which it invests. Enservco maintains its excess cash in various financial institutions, where deposits

may

exceed federally insured amounts at times. 

Accounts Receivable [Policy Text Block]

Accounts Receivable

Accounts receivable are stated at the amounts billed to customers, net of an allowance for uncollectible accounts. The Company provides an allowance for uncollectible accounts based on a review of outstanding receivables, historical collection information and existing economic conditions. The allowance for uncollectible amounts is continually reviewed and adjusted to maintain the allowance at a level considered adequate to cover future losses. The allowance is management's best estimate of uncollectible amounts and is determined based on historical collection experience related to accounts receivable coupled with a review of the current status of existing receivables. The losses ultimately incurred could differ materially in the near term from the amounts estimated in determining the allowance. As of

March 31, 2021, 

and

December 31, 2020,

the Company had an allowance for doubtful accounts of approxim

ately

$359,000

 and

$322,000,

respectively. For t

he

three

 months ended

March 31, 2021

and 

2020,

the Compan

y recorded approximately

$38,000

 and

$300,000

 to bad debt expense, respectively.

Inventory, Policy [Policy Text Block]

Inventories

Inventory consists primarily of propane, diesel fuel and chemicals that are used in the servicing of oil wells and is carried at the lower of cost or net realizable value in accordance with the

first

in,

first

out method (FIFO). The Company periodically reviews the value of items in inventory and provides write-downs or write-offs, of inventory based on its assessment of market conditions. Write-downs and write-offs are charged to cost of goods sold. For the

three

 months ended March

31

,

2021

and

2020,

the Compan

y did

not

recognize any

write-downs or write-offs of inventory

.

Property, Plant and Equipment, Policy [Policy Text Block]

Property and Equipment

Property and equipment consist of (i) trucks, trailers and pickups; (ii)

water transfer pumps, pipe, lay flat hose, trailers, and other support equipment;

(iii) real property which includes land and buildings used for office and shop facilities and wells used for the disposal of water; (iv) other equipment such as tools used for maintaining and repairing vehicles, and (v) office furniture and fixtures, and computer equipment. Property and equipment is stated at cost less accumulated depreciation. The Company capitalizes interest on certain qualifying assets that are undergoing activities to prepare them for their intended use. Interest costs incurred during the fabrication period are capitalized and amortized over the life of the assets. The Company did

not

capitalize any interest during the

three

months ended

March 31, 2021

or

2020.

 The Company charges repairs and maintenance against income when incurred and capitalizes renewals and betterments, which extend the remaining useful life, expand the capacity or efficiency of the assets. Depreciation is recorded on a straight-line basis over estimated useful lives of

5

to

30

years.

Any difference between net book value of the property and equipment and the proceeds of an assets' sale or settlement of an insurance claim is recorded as a gain or loss in the Company's earnings.

Lessee, Leases [Policy Text Block]

Leases

The Company assesses whether an arrangement is a lease at inception. Leases with an initial term of

12

months or less are

not

recorded on the balance sheet. We have elected the practical expedient to

not

separate lease and non-lease components for all assets. Operating lease assets and operating lease liabilities are calculated based on the present value of the future minimum lease payments over the lease term at the lease start date. As most of our leases do

not

provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease start date in determining the present value of future payments. The operating lease asset is increased by any lease payments made at or before the lease start date and reduced by lease incentives and initial direct costs incurred. The lease term includes options to renew or terminate the lease when it is reasonably certain that we will exercise that option. The exercise of lease renewal options is at our sole discretion. The depreciable life of lease assets and leasehold improvements are limited by the lease term. Lease expense for operating leases is recognized on a straight-line basis over the lease term.

The Company conducts a major part of its operations from leased facilities. Each of these leases is accounted for as an operating lease. Operating lease assets and liabilities are recognized at the lease commencement date. Operating lease liabilities represent the present value of lease payments

not

yet paid. Operating lease assets represent our right to use an underlying asset and are based upon the operating lease liabilities adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of operating lease assets.

The Company amortizes leasehold improvements over the shorter of the life of the lease or the life of the improvements. 

The Company has leased trucks and equipment in the normal course of business, which

may

be recorded as operating or finance leases, depending on the term of the lease. The Company recorded 

rental expense on equipment under operating leases over the lease term as it becomes payable; there were

no

 

rent escalation terms associated with these equipment leases. The Company records amortization expense on equipment under finance leases on a straight-line basis as well as interest expense based on our implicit borrowing rate at the date of the lease inception. The equipment leases contain purchase options that allow the Company to purchase the leased equipment at the end of the lease term, based on the market price of the equipment at the time of the lease termination. 

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

Long-Lived Assets

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset

may

not

be recovered. During the

first

quarter of

2021,

the Company concluded that there were

no

further triggering events which could indicate impairment of its long-lived assets. During the

first

quarter of

2020,

the combination of the COVID-

19

pandemic and actions taken by the OPEC+ countries caused oil and gas commodity demand to decrease significantly. The Company determined that these were triggering events which could indicate impairment of its long-lived assets. The Company reviewed both qualitative and quantitative aspects of the business during the analysis of impairment. During the quantitative review, the Company reviews the undiscounted future cash flows in its assessment of whether long-lived assets have been impaired. The Company determined that there was

no

impairment of its long-lived assets during the 

three

months ended March

31,

2021.

Assets Held for Sale

The Company classifies long-lived assets to be sold as held for sale in the period in which all of the following criteria are met: (

1

) management, having the authority to approve the action, commits to a plan to sell the asset or disposal group; (

2

) the asset or disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets; (

3

) an active program to locate a buyer and other actions required to complete the plan to sell the asset or disposal group have been initiated; (

4

) the sale of the asset or disposal group is probable, and transfer of the asset or disposal group is expected to qualify for recognition as a completed sale within

one

year, except if events or circumstances beyond our control extend the period of time required to sell the asset or disposal group beyond

one

year; (

5

) the asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (

6

) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.

We initially measure a long-lived asset or disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held-for-sale criteria are met. Conversely, gains are

not

recognized on the sale of a long-lived asset or disposal group until the date of sale. We assess the fair value of a long-lived asset or disposal group less any costs to sell each reporting period it remains classified as held for sale and report any subsequent changes as an adjustment to the carrying value of the asset or disposal group, as long as the new carrying value does

not

exceed the carrying value of the asset at the time it was initially classified as held for sale. During the years

three

months ended

March 

31,

2021

 and

2020,

the Company recorded

no

impairment charges on its held for sale assets.

Upon determining that a long-lived asset or disposal group meets the criteria to be classified as held for sale, the Company ceases depreciation and reports long-lived assets and/or the assets and liabilities of the disposal group, if material, in the line items assets held for sale in our consolidated balance sheets.

Goodwill and Intangible Assets, Policy [Policy Text Block]

Goodwill and Other Intangible Assets

Goodwill represents the excess purchase price over the fair value of identifiable assets received attributable to business acquisitions and combinations. Goodwill and other intangible assets are measured for impairment at least annually and/or whenever events and circumstances arise that indicate impairment

may

exist, such as a significant adverse change in the business climate. In assessing the value of goodwill, assets and liabilities are assigned to the reporting units and the appropriate valuation methodologies are used to determine fair value at the reporting unit level. Identified intangible assets are amortized using the straight-line method over their estimated useful lives.

During the

first

quarter of

2021,

the Company concluded that there were

no

further triggering events which could indicate impairment of its goodwill and other intangible assets. During the

first

quarter of

2020,

the combination of the COVID-

19

pandemic and actions taken by the OPEC+ countries caused oil and gas commodity demand to decrease significantly. The Company determined that these were triggering events which could indicate impairment of its goodwill and other intangible assets. The Company reviewed both qualitative and quantitative aspects of the business during the analysis of impairment. During the quantitative review, the Company uses both the fair value and discounted future cash flows in its assessment of whether goodwill and other intangible assets have been impaired. The Company determined that there was

no

impairment of its goodwill and other intangible assets during the 

three

months ended

March 31, 2020.

Revenue [Policy Text Block]

Revenue Recognition 

The Company evaluates revenue when we can identify the contract with the customer, the performance obligations in the contract, the transaction price, and we are certain that the performance obligations have been met. Revenue is recognized when the service has been provided to the customer. The vast majority of the Company's services and product offerings are short-term in nature. The time between invoicing and when payment is due under these arrangements is generally

30

to

60

days. Revenue is

not

generated from contractual arrangements that include multiple performance obligations.

The Company's agreements with its customers are often referred to as “price sheets” and sometimes provide pricing for multiple services. However, these agreements generally do

not

authorize the performance of specific services or provide for guaranteed throughput amounts. As customers are free to choose which services, if any, to use based on the Company's price sheet, the Company prices its separate services on the basis of their standalone selling prices. Customer agreements generally do

not

provide for performance, cancellation, termination, or refund type provisions. Services based on price sheets with customers are generally performed under separately issued “work orders” or “field tickets” as services are requested.

Revenue is recognized for certain projects that take more than

one

day projects over time based on the number of days during the reporting period and the agreed upon price as work progresses on each project.

Disaggregation of revenue

See Note

12

 - Segment Reporting for disaggregation of revenue.

Earnings Per Share, Policy [Policy Text Block]

Earnings (Loss) Per Share 

Earnings per Common Share - Basic is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Earnings per Common Share - Diluted earnings is calculated by dividing net income (loss) by the diluted weighted average number of common shares. The diluted weighted average number of common shares is computed using the treasury stock method for common stock that

may

be issued for outstanding stock options, restricted stock and warrants.

As of

March 

31, 2021 and 2020

, there were outstanding stock options, unvested restricted stock awards and warrants to acquire an aggregate

of

1,383,489

 and

247,048

 shares of Company common stock, respectively, which have a potentially dilutive impact on earnings per share. As of

March 

31, 2021 and 2020,

the outstanding stock options and warrants had

no

aggregate intrinsic value

(the difference between the estimated fair value of the Company's common stock on

March 31

, 2021 and 2020,

and the exercise price, multiplied by the number of in-the-money instruments). Dilution is

not

permitted if there are net losses during the period. As such, the Company does

not

show diluted earnings per share for the

three

months ended

March 31, 2021 

and

2020.

Income Tax, Policy [Policy Text Block]

Income Taxes

The Company recognizes deferred tax liabilities and assets based on the differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements that will result in taxable or deductible amounts in future years. 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 of a change in tax rates on deferred tax assets and liabilities will be recognized in income in the period that includes the enactment date. A deferred tax asset or liability that is

not

related to an asset or liability for financial reporting is classified according to the expected reversal date. The Company records a valuation allowance to reduce deferred tax assets to an amount that it believes is more likely than

not

expected to be realized.

The Company accounts for any uncertainty in income taxes by recognizing the tax benefit from an uncertain tax position only if, in the Company's opinion, it is more likely than

not

that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The Company measures the tax benefits recognized in the financial statements from such a position based on the largest benefit that has a greater than

50%

likelihood of being realized upon ultimate resolution. The application of income tax law is inherently complex. Laws and regulations in this area are voluminous and are often ambiguous.  As such, the Company is required to make many subjective assumptions and judgments regarding income tax exposures. Interpretations of and guidance surrounding income tax law and regulations change over time and

may

result in changes to the Company's subjective assumptions and judgments which can materially affect amounts recognized in the consolidated balance sheets and consolidated statements of income. The result of the reassessment of the Company's tax positions did

not

have an impact on the consolidated financial statements.

Interest and penalties associated with tax positions are recorded in the period assessed as Other expense. The Company files income tax returns in the United States and in the states in which it conducts its business operations. The Company

's United States federal income tax filings for tax years

2017

 through

2020

 remain open to examination. In general, the Company's various state tax filings remain open for tax years

2016

 to

2020.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair Value

The Company follows authoritative guidance that applies to all financial assets and liabilities required to be measured and reported on a fair value basis. The Company also applies the guidance to non-financial assets and liabilities measured at fair value on a nonrecurring basis, including non-competition agreements and goodwill. The guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date.  The guidance establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available.

Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions of what market participants would use in pricing the asset or liability based on the best information available in the circumstances.  Beginning in 

2017

the Company valued its warrants using the Binomial Lattice model ("Lattice"). Specific inputs used in the Lattice are the underlying stock price, the exercise price of the warrant, expected dividends, historical volatility, term to expiration and risk-free interest rates. The Company did

not

have any transfers between hierarchy levels during the

three

 months ended March 

31, 2021

. The financial and nonfinancial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement.

The hierarchy is broken down into

three

levels based on the reliability of the inputs as follows:

Level 1: Quoted prices are available in active markets for identical assets or liabilities;

Level 2: Quoted prices in active markets for similar assets and liabilities that are observable for the asset or liability; or

Level 3: Unobservable pricing inputs that are generally less observable from objective sources, such as discounted cash flow models or valuations.

Share-Based Payment Arrangement [Policy Text Block]

Stock-based Compensation

Stock-based compensation cost is measured at the date of grant, based on the calculated fair value of the award as described below, and is recognized over the requisite service period, which is generally the vesting period of the equity grant.

The Company uses the Black-Scholes pricing model as a method for determining the estimated grant date fair value for all stock options awarded to employees, independent contractors, officers, and directors. The expected term of the options is based upon evaluation of historical and expected exercise behavior. The risk-free interest rate is based upon U.S. Treasury rates at the date of grant with maturity dates approximately equal to the expected life of the grant. Volatility is determined upon historical volatility of our stock and adjusted if future volatility is expected to vary from historical experience. The dividend yield is assumed to be

none

as we have

not

paid dividends, nor do we anticipate paying any dividends in the foreseeable future.

The Company

 uses a Lattice model to determine the fair value of certain warrants. The expected term used was the remaining contractual term. Expected volatility is based upon historical volatility over a term consistent with the remaining term. The risk-free interest rate is derived from the yield on

zero

-coupon U.S. government securities with a remaining term equal to the contractual term of the warrants. The dividend yield is assumed to be zero.

The Company used the market-value of Company stock to determine the fair value of the performance-based restricted stock awarded in

2018

and

2019.

Stock based compensation is updated quarterly based on actual forfeitures. The Company used either a Lattice model or the Black-Scholes pricing model to determine the fair value of market-based restricted stock awarded in

2021

 and

2020.

Use of Estimates, Policy [Policy Text Block]

Management Estimates

The preparation of the Company's consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include the realization of accounts receivable, evaluation of impairment of long-lived assets, stock-based compensation expense, income tax provision and the valuation of deferred taxes. Actual results could differ from those estimates.

Reclassification, Comparability Adjustment [Policy Text Block]

Reclassifications

Certain prior-period amounts have been reclassified for comparative purposes to conform to the current

 presentation. These reclassifications have

no

effect on the Company's consolidated statement of operations.
