The Company and Description of Business

1. The Company and Description of Business

The accompanying condensed consolidated financial statements include the accounts of Quest Resource Holding Corporation (“QRHC”) and its subsidiaries, Quest Resource Management Group, LLC (“Quest”), Landfill Diversion Innovations, LLC (“LDI”), Youchange, Inc. (“Youchange”), Quest Vertigent Corporation (“QVC”), Quest Vertigent One, LLC (“QV One”), and Quest Sustainability Services, Inc. (“QSS”) (collectively, “we,” “us,” “our,” or “our company”).

Operations – We are a national provider of waste and recycling services to customers from across multiple industry sectors that are typically larger, multi-location businesses. We create customer-specific programs and perform the related services for the collection, processing, recycling, disposal, and tracking of waste streams and recyclables.

In March 2020, the World Health Organization categorized Coronavirus Disease 2019 (“COVID-19”) as a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. The waste management and recycling services we provide are currently designated an essential critical infrastructure business under the President’s COVID-19 guidance, the continued operation of which is vital for national public health, safety and national economic security. The extent of the impact of the COVID-19 outbreak on our operational and financial performance will depend on certain developments, including the duration and spread of the outbreak, its impact on our customers and subcontractors, and the range of governmental and community reactions to the pandemic, which are uncertain and cannot be fully predicted at this time.

Principles of Presentation and Consolidation

The condensed consolidated financial statements included herein have been prepared by us without audit pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and should be read in conjunction with our audited financial statements for the year ended December 31, 2019. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted as permitted by the SEC, although we believe the disclosures that are made are adequate to make the information presented herein not misleading.

The accompanying condensed consolidated financial statements reflect, in our opinion, all normal recurring adjustments necessary to present fairly our financial position at March 31, 2020 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2019 condensed consolidated balance sheet data from audited financial statements; however, we did not include all disclosures required by GAAP. As QRHC, Quest, LDI, Youchange, QVC, QV One, and QSS each operate as environmental-based service companies, we did not deem segment reporting necessary.

All intercompany accounts and transactions have been eliminated in consolidation. Interim results are subject to seasonal variations, and the results of operations for the three months ended March 31, 2020 are not necessarily indicative of the results to be expected for the full year.

Recent Accounting Pronouncements

Adopted

On January 1, 2020, we adopted Accounting Standards Update (“ASU”) 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40). The ASU allows companies to capitalize implementation costs incurred in a hosting arrangement that is a service contract over the term of the hosting arrangement, including periods covered by renewal options that are reasonably certain to be exercised. This guidance also requires entities to present the expense in the same line item in the statement of operations as the fees associated with the hosting arrangement and classify payments for capitalized implementation costs in the statement of cash flows in the same manner as payments made for fees associated with the hosting element. The adoption of the standard did not have a material effect on our consolidated financial statements.

In March 2020, the Financial Accounting Standards Board (“FASB”) issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This standard provides operational guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting due to the cessation of the London Interbank Offered Rate (LIBOR). The amendments are elective and apply to all entities that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The expedients and exceptions provided by the amendments generally do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. As further discussed in Note 6, our ABL facility provides procedures for determining a replacement or alternative rate in the event that LIBOR is unavailable. As such, we do not expect the transition away from LIBOR to have a material impact on our financial statements.

Pending Adoption

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326), which provides guidance on measuring credit losses on financial instruments. The amended guidance replaces current incurred loss impairment methodology of recognizing credit losses when a loss is probable with a methodology that reflects expected credit losses and requires a broader range of reasonable and supportable information to assess credit loss estimates. ASU 2016-13 is effective for us on January 1, 2023. We are assessing the provisions of this amended guidance; however, the adoption of the standard is not expected to have a material effect on our consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes – (Topic 740), which simplifies the accounting for income taxes by removing certain exceptions and amending guidance to improve consistent application of accounting over income taxes. This guidance is effective January 1, 2021 with early adoption permitted. The adoption of the standard is not expected to have a material effect on our consolidated financial statements.

There have been no other recent accounting pronouncements or changes in accounting pronouncements that have been issued but not yet adopted that are of significance, or potential significance, to us.

Depreciation expense for the three months ended March 31, 2019 was $67,516, including $33,498 of depreciation expense reflected within “Cost of revenue.”

We recorded a right-of-use operating lease asset related to our corporate office lease upon the adoption of ASC 842 effective January 1, 2019. Refer to Note 7, Leases for additional information.

On February 20, 2018 (the “Closing Date”), we entered into an Asset Purchase Agreement with Earth Media Partners, LLC to sell certain assets of our wholly owned subsidiary, Earth911, Inc., in exchange for a 19% interest in Earth Media Partners, LLC, which was recorded as an investment in the amount of $246,585 as of the Closing Date, and a potential future earn-out amount of approximately $350,000. The net assets sold related to the Earth911.com website business and consisted primarily of the website and its content and customers, deferred revenue, and accounts receivable as of the Closing Date. Earth911, Inc. was subsequently renamed Quest Sustainability Services, Inc. The carrying amount of our investment in Earth Media Partners, LLC is included in “Security deposits and other assets” and we have an accrued receivable in the amount of $188,429 related to the earn-out included in “Accounts receivable” as of March 31, 2020.

We have no indefinite-lived intangible assets other than goodwill. The goodwill is not deductible for tax purposes.

We performed our annual impairment analysis for goodwill and other intangible assets in the third quarter of 2019 with no impairment recorded. During the 2019 impairment assessment, our operations unit had a fair value substantially in excess of the carrying value. In addition to the annual impairment test, we are required to regularly assess whether a triggering event has occurred which would require interim testing. We considered the current and expected future economic and market conditions surrounding the COVID-19 pandemic and its impact on our operations. Currently, we have determined that a triggering event has not occurred that would require an interim impairment test to be performed. However, we refer you to our comment in Note 1 as it relates to the impact of COVID-19 and certain economic uncertainties.

Notes Payable

6. Notes Payable

We entered into a Loan, Security and Guaranty Agreement (the “Citizens Loan Agreement”), dated as of February 24, 2017, with Citizens Bank, National Association as a lender, and as administrative agent, collateral agent, and issuing bank, which provides for an asset-based revolving credit facility (the “ABL Facility”) of up to $20 million.

Each loan under the ABL Facility bears interest, at our option, at either the Base Rate, as defined in the Citizens Loan Agreement, plus a margin ranging from 1.0% to 1.5% (4.50% as of March 31, 2020), or the LIBOR lending rate for the interest period in effect, plus a margin ranging from 2.0% to 2.5% (3.89% as of March 31, 2020). The maturity date of the ABL Facility is February 24, 2022.

LIBOR is expected to be discontinued after 2021. The ABL Facility provides procedures for determining a replacement or alternative rate in the event that LIBOR is unavailable. However, there can be no assurances as to whether such replacement or alternative rate will be more or less favorable than LIBOR. We intend to monitor the developments with respect to the potential phasing out of LIBOR after 2021 and will work with Citizens Bank, National Association to ensure any transition away from LIBOR will have minimal impact on our financial condition. We however can provide no assurances regarding the impact of the discontinuation of LIBOR on the interest rate that we would be required to pay or on our financial condition.

The ABL Facility contains certain specific financial covenants regarding a minimum liquidity requirement and a minimum fixed charge coverage ratio. In addition, the ABL Facility contains negative covenants limiting, among other things, additional indebtedness, transactions with affiliates, additional liens, sales of assets, dividends, investments and advances, mergers and acquisitions, and other matters customarily restricted in such agreements.

The amount of interest expense related to borrowings for the three months ended March 31, 2020 and 2019 was $60,845 and $86,742, respectively. Debt issuance cost of $469,507 is being amortized to interest expense over the term of the ABL Facility. As of March 31, 2020, the unamortized portion of the debt issuance costs was $179,978. The amount of interest expense related to the amortization of the discount on the ABL Facility for the three months ended March 31, 2020 and 2019 was $23,475. As of March 31, 2020, the ABL Facility borrowing base availability was $11,221,000, of which $4,733,003 principal was outstanding. The outstanding liability as of March 31, 2020 was $4,553,025, net of unamortized debt issuance cost of $179,978.

As a result of the uncertainty surrounding the COVID-19 pandemic and its impact on our operating results, which cannot be reasonably estimated at this time, we applied for, and on May 5, 2020, we received loan proceeds of $1.4 million under the Paycheck Protection Program (“PPP”) under a promissory note from BMO Harris Bank National Association (the “PPP Loan”). The PPP was established as part of the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) and is administered by the U.S. Small Business Administration. The PPP Loan has a two-year term and bears interest at an annual interest rate of 1%. Monthly principal and interest payments are deferred for six months, and the maturity date is April 30, 2022.

Under the terms of the CARES Act, PPP loan recipients can apply for and be granted forgiveness for all or a portion of the loan granted under the PPP. Such forgiveness will be determined, subject to limitations, based on the use of loan proceeds for payment of payroll costs and any payments of mortgage interest, rent, and utilities. However, no assurance is provided that forgiveness for any portion of the PPP Loan will be obtained.

ASU 2016-02 Adoption

On January 1, 2019, we adopted ASU 2016-02, Leases (Topic 842), and the related amendments. We used the optional transition method of adoption, in which the cumulative effect of initially applying the new standard, as of January 1, 2019, to our existing leases was approximately $2.0 million and $2.2 million to record the operating lease right-of-use asset and the related liabilities, respectively, all of which relate to our corporate office lease. Leases with terms of 12 months or less are not recorded on the balance sheet.

When we have the option to extend the lease term, terminate the lease before the contractual expiration date, or purchase the leased asset, and if it is reasonably certain that we will exercise the option, we consider these options in determining the classification and measurement of the lease.

We lease certain equipment to a customer under a lease arrangement that expires in 2020. The capital lease receivable amounts were approximately $2,400 and $5,000 at March 31, 2020 and December 31, 2019, respectively, the majority of which was included in Prepaid expenses and other current assets.

Balance Sheet Classification

The table below presents the lease related assets and liabilities recorded on the balance sheet. Right-of-use assets and related liabilities related to finance leases at March 31, 2020 are de minimis and mature in less than 12 months.

	March 31,		December 31,

Other long-term liabilities		977,186		1,136,583
Total operating lease liabilities	$	1,608,946	$	1,764,479

Lease Costs

For the three months ended March 31, 2020, we recorded approximately $150,000 of fixed cost operating lease expense. Our operating lease expense is offset by a minimum annual incentive received from a local Economic Development Council, which is accrued monthly and will continue over the term of the lease through August 2022. This minimum annual incentive is $63,000, which will increase to $93,600 for the annual incentive period starting September 2020 through the remainder of the lease term.

Effective December 1, 2019, we subleased a portion of our corporate office space to a single tenant. The sublease agreement is accounted for as an operating lease and we recognize sublease income as an offset to operating lease expense on a straight-line basis over the term of the sublease agreement through August 2022. Sublease income, net of amortized leasing costs, for the three months ended March 31, 2020 was approximately $11,000.

Cash paid for operating leases approximated operating lease expense and non-cash right of use asset amortization for the three months ended March 31, 2020. We did not obtain any new operating lease right-of-use assets in the three months ended March 31, 2020.

Other Information

Our office lease had a remaining term of 2.5 years as of March 31, 2020, and we used an effective interest rate of 2.456%, which was our incremental borrowing rate in effect at the inception of the lease as our lease does not provide a readily determinable implicit rate.

The future minimum lease payments required under our office lease as of March 31, 2020 were as follows:

	Amount
2020	$	498,150
2021		664,200

Revenue From Contract With Customer [Abstract]

Revenue

8. Revenue

Operating Revenues

We provide businesses with services to reuse, recycle, and dispose of a wide variety of waste streams and recyclables generated by their operations. In addition, we have product sales and other revenue primarily from sales of products, such as antifreeze and windshield washer fluid, as well as minor ancillary services.

Revenue Recognition

We recognize revenue as services are performed or products are delivered. For example, we recognize revenue as waste and recyclable material are collected or when products are delivered. We recognize revenue net of any contracted pricing discounts or rebate arrangements.

We generally recognize revenue for the gross amount of consideration received as we are generally the primary obligor (or principal) in our contracts with customers as we hold complete responsibility to the customer for contract fulfillment. We record amounts collected from customers for sales tax on a net basis.

Disaggregation of Revenue

The following table presents our revenue disaggregated by source. Three customers accounted for 54.0% of revenue for the three months ended March 31, 2020, and three customers accounted for 59.7% of revenue for the three months ended March 31, 2019. We operate primarily in the United States, with minor services in Canada.

Total revenue	$	25,331,814	$	26,649,041

Contract Balances

Our incremental direct costs of obtaining a customer contract are generally deferred and amortized to selling, general, and administrative expense or as a reduction to revenue (depending on the nature of the cost) over the estimated life of the customer contract. We classify our contract acquisition costs as current or noncurrent based on the timing of when we expect to recognize the amortization and are included in other assets.

As of March 31, 2020 and December 31, 2019, we had $172,500 and $113,750, respectively, of deferred contract costs. During the three months ended March 31, 2020, we amortized $56,250 of deferred contract costs to selling, general, and administrative expense. During the three months ended March 31, 2019, we amortized $53,750 of deferred contract costs to selling, general, and administrative expense.

We bill certain customers in advance, and, accordingly, we defer recognition of related revenues as a contract liability until the services are provided and control is transferred to the customer. As of March 31, 2020 and December 31, 2019, we had $22,610 and $19,644, respectively, of deferred revenue, the majority of which was classified in “Deferred revenue and other current liabilities.”

Income Taxes

9. Income Taxes

Our statutory income tax rate is anticipated to be 27%. We had an income tax benefit of $52,732 for the three months ended March 31, 2020 based on current estimated state tax apportionments, and income tax expense of $54,769 for the three months ended March 31, 2019, which was attributable to state tax obligations for states with no net operating loss carryforwards, and the reserve against the benefit of the net operating losses at the federal level.

We compute income taxes using the asset and liability method in accordance with FASB ASC Topic 740, Income Taxes. Under the asset and liability method, we determine deferred income tax assets and liabilities based on the differences between the financial reporting and tax bases of assets and liabilities and measure them using currently enacted tax rates and laws. We provide a valuation allowance to reduce the amount of deferred tax assets that, based on available evidence, is more likely than not to be realized. Realization of our net operating loss carryforward was not reasonably assured as of March 31, 2020 and December 31, 2019, and we had recorded a valuation allowance of $12,516,000 and $12,452,000, respectively, against deferred tax assets in excess of deferred tax liabilities in the accompanying condensed consolidated financial statements. As of March 31, 2020 and December 31, 2019, we had federal income tax net operating loss carryforwards of approximately $16,800,000 and $17,200,000, respectively, which expire at various dates ranging from 2031-2037.

Earnings Per Share [Abstract]

Net Loss per Share

12. Net Loss per Share

We compute basic net income (loss) per share using the weighted average number of shares of common stock outstanding plus the number of common stock equivalents for DSUs during the period. We compute diluted net income (loss) per share using the weighted average number of shares of common stock outstanding during the period, adjusted for the dilutive effect of common stock equivalents. In periods where losses are reported, the weighted average number of shares of common stock outstanding excludes common stock equivalents because their inclusion would be anti-dilutive. Dilutive potential common shares consist of the incremental common shares issuable upon the exercise of outstanding stock options. Dilutive potential securities are excluded from the computation of earnings per share if their effect is antidilutive. The dilutive effect of outstanding stock options and warrants is reflected in diluted earnings per share by application of the treasury stock method.

The computation of basic and diluted net income (loss) per share attributable to common stockholders is as follows:

During the year ended December 31, 2019, three stockholders sold approximately 4.3 million shares of our common stock in a registered public offering. In a separate private transaction, a certain selling stockholder sold 1,750,000 shares of our common stock. The offering and private transaction, together the “Transactions”, closed on April 11, 2019. We did not receive any proceeds from sales by the selling stockholders in the Transactions. We incurred costs and expenses in connection with the Transactions, consisting of various registration, due diligence, printing, and professional service fees and expenses, and such costs, less amounts reimbursed by the selling stockholders at the closing of the Transactions, were approximately $248,000. Of the $248,000, approximately $230,000 was included in selling, general, and administrative expense for the three months ended March 31, 2019.

Accounting Policies [Abstract]
Principles of Presentation and Consolidation	Principles of Presentation and Consolidation The condensed consolidated financial statements included herein have been prepared by us without audit pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and should be read in conjunction with our audited financial statements for the year ended December 31, 2019. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted as permitted by the SEC, although we believe the disclosures that are made are adequate to make the information presented herein not misleading. The accompanying condensed consolidated financial statements reflect, in our opinion, all normal recurring adjustments necessary to present fairly our financial position at March 31, 2020 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2019 condensed consolidated balance sheet data from audited financial statements; however, we did not include all disclosures required by GAAP. As QRHC, Quest, LDI, Youchange, QVC, QV One, and QSS each operate as environmental-based service companies, we did not deem segment reporting necessary. All intercompany accounts and transactions have been eliminated in consolidation. Interim results are subject to seasonal variations, and the results of operations for the three months ended March 31, 2020 are not necessarily indicative of the results to be expected for the full year.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted On January 1, 2020, we adopted Accounting Standards Update (“ASU”) 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40). The ASU allows companies to capitalize implementation costs incurred in a hosting arrangement that is a service contract over the term of the hosting arrangement, including periods covered by renewal options that are reasonably certain to be exercised. This guidance also requires entities to present the expense in the same line item in the statement of operations as the fees associated with the hosting arrangement and classify payments for capitalized implementation costs in the statement of cash flows in the same manner as payments made for fees associated with the hosting element. The adoption of the standard did not have a material effect on our consolidated financial statements. In March 2020, the Financial Accounting Standards Board (“FASB”) issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This standard provides operational guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting due to the cessation of the London Interbank Offered Rate (LIBOR). The amendments are elective and apply to all entities that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The expedients and exceptions provided by the amendments generally do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. As further discussed in Note 6, our ABL facility provides procedures for determining a replacement or alternative rate in the event that LIBOR is unavailable. As such, we do not expect the transition away from LIBOR to have a material impact on our financial statements. Pending Adoption In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326), which provides guidance on measuring credit losses on financial instruments. The amended guidance replaces current incurred loss impairment methodology of recognizing credit losses when a loss is probable with a methodology that reflects expected credit losses and requires a broader range of reasonable and supportable information to assess credit loss estimates. ASU 2016-13 is effective for us on January 1, 2023. We are assessing the provisions of this amended guidance; however, the adoption of the standard is not expected to have a material effect on our consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, Income Taxes – (Topic 740), which simplifies the accounting for income taxes by removing certain exceptions and amending guidance to improve consistent application of accounting over income taxes. This guidance is effective January 1, 2021 with early adoption permitted. The adoption of the standard is not expected to have a material effect on our consolidated financial statements. There have been no other recent accounting pronouncements or changes in accounting pronouncements that have been issued but not yet adopted that are of significance, or potential significance, to us.
