QUEST RESOURCE HOLDING CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

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 reuse, recycling, and disposal services that enable our customers to achieve and satisfy their environmental and sustainability goals and responsibilities.  We provide businesses across multiple industry sectors with single source solutions for the reuse, recycling, and disposal of a wide variety of waste streams and recyclables generated by their operations.

2. Summary of Significant Accounting Policies

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, 2018. 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, 2019 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2018 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, 2019 are not necessarily indicative of the results to be expected for the full year.

Net Loss per Share

We compute basic net loss per share by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. We have other potentially dilutive securities outstanding that are not shown in a diluted net loss per share calculation because their effect in both 2019 and 2018 would be anti-dilutive. These potentially dilutive securities include stock options and warrants and totaled 3,921,048 and 3,497,424 shares at March 31, 2019 and 2018, respectively.

The following table sets forth the anti-dilutive securities excluded from diluted loss per share:

	March 31,
	2019		2018
	(Unaudited)		(Unaudited)
Anti-dilutive securities excluded from diluted loss per share:
Stock options		2,187,483		1,763,859
Warrants		1,733,565		1,733,565
Total anti-dilutive securities excluded from diluted loss per share		3,921,048		3,497,424

Recent Accounting Pronouncements

Adopted

On January 1, 2019, we adopted Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842), using a modified retrospective approach with an effective date as of January 1, 2019.  Accordingly, prior year financial statement data is presented in accordance with the previous ASC Topic 840, Leases, and no retrospective adjustments were made to the comparative periods presented.  We elected the package of practical expedients, which allowed us to carryforward our historical assessment of (1) whether contracts are or contain leases, (2) lease classification, and (3) initial direct costs.  As of January 1, 2019, we recognized an operating right-of-use asset of approximately $2.0 million and corresponding operating lease liabilities of approximately $2.2 million.  Finance lease assets were not impacted by the adoption of ASC 842, as finance lease liabilities and the corresponding assets were already recorded on the

6

balance sheet under ASC 840.  The adoption did not materially impact our results of operations or cash flows and no cumulative adjustment to accumulated deficit was necessary as of January 1, 2019.  Refer to Note 7, Leases for additional information and enhanced disclosures related to this amended guidance.

On January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), using the full retrospective approach for all ongoing customer contracts.  Refer to Note 8, Revenue for additional information and disclosures related to this amended guidance.

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, 2020, with early adoption permitted on January 1, 2019.  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.

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.

3. Property and Equipment, net, and Other Assets

At March 31, 2019 and December 31, 2018, property and equipment, net, and other assets consisted of the following:

	March 31,		December 31,
	2019		2018
	(Unaudited)
Property and equipment, net of accumulated depreciation of $2,591,217      and $2,523,700 as of March 31, 2019 and December 31, 2018,      respectively	$	547,002	$	614,518
Right-of-use operating lease asset		2,009,904		—
Security deposits and other assets		366,239		353,507
Property and equipment, net, and other assets	$	2,923,145	$	968,025

We compute depreciation using the straight-line method over the estimated useful lives of the property and equipment. Depreciation expense for the three months ended March 31, 2019 was $67,516, including $33,498 of depreciation expense reflected within “Cost of revenue” in our condensed consolidated statements of operations as it related to assets used in directly servicing customer contracts.  Depreciation expense for the three months ended March 31, 2018 was $103,310, including $45,296 of depreciation expense reflected within “Cost of revenue.”

We recorded a right-of-use operating lease asset of $2.0 million 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.  Following the Closing Date, Earth911, Inc. was subsequently renamed Quest Sustainability Services, Inc.  In addition to our investment in Earth Media Partners, LLC, we accrued a receivable in the amount of $74,298 related to the earn-out as of March 31, 2019.  The carrying amount of our investment and the accrued earn-out receivable are included in other assets.

6. Revolving Credit Facility

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 and an equipment loan facility in the maximum principal amount of $2.0 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% (6.75% as of March 31, 2019), or the LIBOR lending rate for the interest period in effect, plus a margin ranging from 2.0% to 2.5% (4.85% as of March 31, 2019). The maturity date of the ABL Facility is February 24, 2022.  

We had no borrowings under the equipment loan facility, which were required to be requested no later than February 24, 2019.  

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, 2019 and 2018 was $86,742 and $84,288, respectively.  Debt issuance cost of $469,507 is being amortized to interest expense over the term of the ABL Facility beginning March 1, 2017.  As of March 31, 2019, the unamortized portion of the debt issuance costs was $273,879.  The amount of interest expense related to the amortization of the discount on the ABL Facility for the three months ended March 31, 2019 and 2018 was $23,475.  As of March 31, 2019, the ABL Facility borrowing base availability was $12,811,000 and the outstanding liability was $5,157,659, net of unamortized debt issuance cost of $273,879.

7. Leases

ASU 2016-02 Adoption

On January 1, 2019, we adopted ASU 2016-02, Leases (Topic 842), and the related amendments (collectively “ASC 842”).  We used the optional transition method of adoption, in which the cumulative effect of initially applying the new standard, as of January 1, 2109, 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.  Under this method of adoption, the comparative information in the condensed consolidated financial statements has not been revised and continues to be reported under the previous applicable lease accounting guidance (ASC 840).  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.

As of December 31, 2018, leases classified as capital leases under ASC 840 were included in Property and equipment, net and represented almost fully depreciated office equipment with a negligible book value.

We lease certain equipment to a customer under a lease arrangement that expires in 2020.  The capital lease receivable amounts are approximately $150,000 at March 31, 2019, the majority of which is 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, 2019 are de minimis and mature in less than 12 months.

	March 31,
	2019
Operating Leases:
Right-of-use operating lease asset:
Property and equipment, net and other assets	$	2,009,904
Lease Liabilities:
Accounts payable and accrued liabilities	$	594,642
Other long-term liabilities		1,608,946
Total operating lease liabilities	$	2,203,588

Lease Costs

For the three months ended March 31, 2019, 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 (“EDC”),

9

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.  

Cash paid for operating leases approximated operating lease expense and non-cash right of use asset amortization for the three months ended March 31, 2019.  We did not obtain any new operating lease right-of-use assets in the three months ended March 31, 2019.

Other Information

Our office lease had a remaining term of 3.5 years as of March 31, 2019, 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, 2019 were as follows:    

Year Ending December 31,	Amount
2019	$	476,190
2020		664,200
2021		664,200
2022		498,150
Total lease payments		2,302,740
Less:  Interest		99,152
Present value of lease liabilities	$	2,203,588

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.  Sales and usage-based taxes are excluded from revenue.  Three customers accounted for 59.7% of revenue for the three months ended March 31, 2019, and three customers accounted for 48.4% of revenue for the three months ended March 31, 2018.  We operate primarily in the United States, with minor services in Canada.

	Three Months Ended March 31,
	2019		2018
	(Unaudited)		(Unaudited)
Revenue Type:
Services	$	24,054,519	$	22,005,572
Product sales and other		2,594,522		2,690,351
Total revenue	$	26,649,041	$	24,695,923

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, 2019 and December 31, 2018, we had $165,000 and $7,448, respectively, of deferred contract costs.  During the three months ended March 31, 2019, we amortized $53,750 and nil of deferred contract costs to selling, general, and administrative expense and as a reduction to income, respectively.  During the three months ended March 31, 2018, we amortized $33,333 and $18,069 of deferred contract costs to selling, general, and administrative expense and as a reduction to income, respectively.  

10

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, 2019 and December 31, 2018, we had $50,268 and $69,473, respectively, of deferred revenue, the majority of which was classified in “Deferred revenue and other current liabilities.”

9. Income Taxes

Our statutory income tax rate is anticipated to be 27%.  However, we had income tax expense of $54,769 on a net operating loss for the quarter ended March 31, 2019, which is attributable to state tax obligations for states with no net operating loss carryforwards, and the continued 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, 2019 and December 31, 2018, and we had recorded a valuation allowance of $12,195,000 and $12,202,000, respectively, against deferred tax assets in excess of deferred tax liabilities in the accompanying condensed consolidated financial statements. As of March 31, 2019 and December 31, 2018, we had federal income tax net operating loss carryforwards of approximately $18,900,000, which expire at various dates ranging from 2031-2037.

10. Fair Value of Financial Instruments

Our financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, deferred revenue, and the ABL Facility. We do not believe that we are exposed to significant interest, currency, or credit risks arising from these financial instruments.  The fair values of these financial instruments approximate their carrying values using Level 3 inputs, based on their short maturities or, for the ABL Facility, based on borrowing rates currently available to us for loans with similar terms and maturities.

11. Stockholders’ Equity

Preferred Stock – Our authorized preferred stock consists of 10,000,000 shares of preferred stock with a par value of $0.001, of which no shares have been issued or are outstanding.

Common Stock – Our authorized common stock consists of 200,000,000 shares of common stock with a par value of $0.001, of which 15,328,870 shares were issued and outstanding as of March 31, 2019 and December 31, 2018.

Employee Stock Purchase Plan – On September 17, 2014, our stockholders approved our 2014 Employee Stock Purchase Plan (“ESPP”).  We recorded expense of $6,557 and $2,044 related to the ESPP for the three months ended March 31, 2019 and 2018, respectively.

Warrants – At March 31, 2019, we had outstanding exercisable warrants to purchase 1,733,565 shares of common stock.    

The following table summarizes the warrants issued and outstanding as of March 31, 2019:

	Date of		Exercise		Shares of
Description	Issuance	Expiration	Price		Common Stock

Warrants	3/30/2016	03/30/2021	$	3.88		521,060
Total warrants issued and outstanding						1,733,565

Stock Options – We recorded stock option expense of $197,474 and $222,079 for the three months ended March 31, 2019 and 2018, respectively.  The following table summarizes the stock option activity for the three months ended March 31, 2019:

12.  Subsequent Event

Subsequent to quarter end, three stockholders sold approximately 4.3 million shares of our common stock in a registered public offering that closed on April 11, 2019.  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 $245,000.  Of the $245,000, approximately $230,000 is included in selling, general, and administrative expense for the three months ended March 31, 2019, with the remaining $15,000 to be recorded in April 2019.

Overview

We were incorporated in Nevada in July 2002 under the name BlueStar Financial Group, Inc. On July 16, 2013, we acquired all of the issued and outstanding membership interests of Quest Resource Management Group, LLC, or Quest, held by Quest Resource Group LLC, or QRG, comprising 50% of the membership interests of Quest, or the Quest Interests. Our wholly owned subsidiary, Quest Sustainability Services, Inc., or QSS, (formerly known as Earth911, Inc.), held the remaining 50% of the membership interests of Quest for several years.  Concurrently with our acquisition of the Quest Interests, we assigned the Quest Interests to QSS so that QSS now holds 100% of the issued and outstanding membership interests of Quest. On October 28, 2013, we changed our name to Quest Resource Holding Corporation.

This “Management’s Discussion and Analysis of Financial Condition and Results of Operations” is based on and relates primarily to the operations of QRHC and Quest.

Three Months Ended March 31, 2019 compared to Three Months Ended March 31, 2018

Revenue

For the quarter ended March 31, 2019, revenue was $26.6 million, an increase of $2.0 million, or 7.9%, compared with $24.7 million for the quarter ended March 31, 2018.  

Cost of Revenue/Gross Profit

Cost of revenue increased $1.0 million to $22.1 million for the quarter ended March 31, 2019 from $21.1 million for the quarter ended March 31, 2018.  The increase was primarily due to increased services from both our continuing and new customer base and changes in our mix of services, partially offset by decreased cost of certain contracted services.

For the quarter ended March 31, 2019, gross profit was $4.5 million, an increase of $1.0 million, or 28.0%, compared with $3.5 million for the quarter ended March 31, 2018.  The gross profit margin rose to 17.0% for the first quarter of 2019 compared with 14.4% for the first quarter of 2018.  The changes in gross profit and the increase in gross profit margin percentage for the three months ended March 31, 2019 were primarily due to the net effect of increased services from both our continuing and new customer base, changes in our mix of services, and lower cost of certain subcontracted services.

Revenue, gross profit, and gross profit margins are affected period to period by the volumes of waste and recycling materials generated by our customers, the frequency and type of services provided, the price and mix of the services provided, commodity index adjustments for recycled materials, and the cost and mix of subcontracted services provided in any one reporting period.

Operating Expenses

Operating expenses were $4.5 million and $4.7 million for the three months ended March 31, 2019 and 2018, respectively.  

Selling, general, and administrative expenses were $4.2 million and $3.8 million for the three months ended March 31, 2019 and 2018, respectively, an increase of approximately $462,000. The increase was primarily related to increases in labor related expenses of approximately $156,000, professional fees of $127,000, advertising and tradeshow expenses of $50,000 and travel of $24,000.  For the three months ended March 31, 2019, professional fees included costs of approximately $230,000 related to selling shareholder transactions.  See Note 12 to our condensed consolidated financial statements for further discussion of the selling shareholder transactions.

Operating expenses also included depreciation and amortization of approximately $326,000 and $985,000 for the three months ended March 31, 2019 and 2018, respectively, a decrease of approximately $659,000.  The decrease in depreciation and amortization was primarily due to lower amortization related to certain intangible assets that were fully amortized as of July 2018.  

Interest Expense

For the three months ended March 31, 2019, interest expense decreased by $12,000 to $112,000 from $124,000 for the three months ended March 31, 2018.  The decreases were primarily due to lower average outstanding balances on our revolving credit facility.  See Note 6 to our condensed consolidated financial statements for a discussion of our revolving credit facility.

Income Taxes

We recorded a provision for income taxes of $55,000 for the three months ended March 31, 2019, primarily related to tax basis net income at the state level for several states with no net operating loss carryforwards.  For the three months ended March 31, 2018, we were in a net loss position and recorded no provision.

Net Loss

Net loss for the quarter ended March 31, 2019 was $164,000 compared with a net loss of $1.3 million for the quarter ended March 31, 2018.  The explanations above detail the majority of the changes related to the decrease in net loss.

Our operating results, including revenue, operating expenses, and operating margins, will vary from period to period depending on commodity prices of recycled materials, the volume and mix of services provided, as well as customer mix during the reporting period.

Loss per Share

Net loss per basic and diluted share was $(0.01) for the quarter ended March 31, 2019 compared with a net loss per basic and diluted share of ($0.09) for the quarter ended March 31, 2018. The weighted average number of shares of common stock outstanding were approximately 15.3 million for both the three months ended March 31, 2019 and the three months ended March 31, 2018.  

Adjusted EBITDA

We use the non-GAAP measurement of earnings before interest, taxes, depreciation, amortization, stock-related compensation charges, and other adjustments, or “Adjusted EBITDA,” as another metric to evaluate our performance.  Adjusted EBITDA is a non-GAAP measure that we believe can be helpful in assessing our overall performance as an indicator of operating and earnings quality.

14

We suggest that Adjusted EBITDA be viewed in conjunction with our reported financial results or other financial information prepared in accordance with GAAP.  For the three months ended March 31, 2019, other adjustments of $230,211 included costs related to selling shareholders transactions.  See Note 12 to our condensed consolidated financial statements for a discussion of the selling shareholders transactions.  For the three months ended March 31, 2018, other adjustments of $48,845 included legal fees related to our sale of certain Earth911 assets.

The following table reflects Adjusted EBITDA for the three months ended March 31, 2019 and 2018:

Income tax expense		54,769			—
Adjusted EBITDA	$	796,355		$	114,331

Liquidity and Capital Resources

As of March 31, 2019 and December 31, 2018, we had $2.1 million in cash and cash equivalents. Working capital was $3.9 million as of March 31, 2019 compared with $4.0 million as of December 31, 2018.

We derive our primary sources of funds for conducting our business activities from operating revenues; borrowings under our credit facilities; and the placement of our equity securities to investors. We require working capital primarily to carry accounts receivable, service debt, purchase capital assets, fund operating expenses, address unanticipated competitive threats or technical problems, withstand adverse economic conditions, fund potential acquisition transactions, and pursue goals and strategies.

We believe our existing cash and cash equivalents of $2.1 million, our borrowing capacity under our $20.0 million ABL Facility (which was $12.8 million as of March 31, 2019), and cash expected to be generated from operations will be sufficient to fund our operations for the next 12 months.  In addition, we believe we can access the capital markets with placements of our securities, if necessary or desirable.

Cash Flows

The following discussion relates to the major components of our cash flows for the three months ended March 31, 2019 and 2018.

Cash Flows from Operating Activities

Net cash provided by operating activities was $46,000 for the three months ended March 31, 2019 compared with $1.8 million for the three months ended March 31, 2018.

Net cash provided by operating activities for the three months ended March 31, 2019 related primarily to the net effect of the following:

• net loss of $164,000;

• offset by non-cash items of $0.6 million, which primarily related to depreciation, amortization of intangible assets, provision for doubtful accounts, and stock-based compensation; and

• net cash used in the net change in operating assets and liabilities of $(0.4) million, primarily associated with relative changes in accounts receivable, accounts payable, and accrued liabilities.

Net cash provided by operating activities for the three months ended March 31, 2018 related primarily to the net effect of the following:

• net loss of $1.3 million;

• offset by non-cash items of $1.3 million, which primarily related to depreciation, amortization of intangible assets, provision for doubtful accounts, and stock-based compensation; and

15

• net cash provided by the net change in operating assets and liabilities of $1.8 million, primarily associated with relative changes in accounts receivable, accounts payable, and accrued liabilities.

Our business, including revenue, operating expenses, and operating margins, may vary depending on the blend of services we provide to our customers, the terms of customer contracts, commodity contracts, and our business volume levels. Our operating activities may require additional cash in the future from our debt facilities and/or equity financings depending on the level of our operations.

Cash Flows from Investing Activities

Cash used in investing activities for the three months ended March 31, 2019 and 2018 was $41,000 and $60,000, respectively, primarily from costs related to software development.  

Cash Flows from Financing Activities

Net cash used in financing activities was $61,000 for the three months ended March 31, 2019, primarily from net repayments on our revolving credit facility.  Net cash used in financing activities was $1.7 million for the three months ended March 31, 2018, primarily from net repayments on our revolving credit facility.  See Note 6 to our condensed consolidated financial statements for a discussion of the ABL Facility.

Inflation

We do not believe that inflation had a material impact on us during the three months ended March 31, 2019 and 2018.

Critical Accounting Estimates and Policies

Our discussion and analysis of our financial condition and results of operations are based on our condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of our condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to areas that require a significant level of judgment or are otherwise subject to an inherent degree of uncertainty. These areas include carrying amounts of accounts receivable, goodwill and other intangible assets, stock-based compensation expense, and deferred taxes. We base our estimates on historical experience, our observance of trends in particular areas, and information or valuations and various other assumptions that we believe to be reasonable under the circumstances and which form the basis for making judgments about the carrying value of assets and liabilities that may not be readily apparent from other sources. Actual amounts could differ significantly from amounts previously estimated.  For a discussion of our critical accounting policies, refer to Part I, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2018 Annual Report.  There have been no changes in our critical accounting policies during the first three months of 2019.

Recent Accounting Pronouncements

See Note 2 to our condensed consolidated financial statements.

Off-Balance Sheet Arrangements

We have no off-balance sheet debt or similar obligations. We have no transactions or obligations with related parties that are not disclosed, consolidated into, or reflected in our reported results of operations or financial position. We do not guarantee any third-party debt.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Not applicable.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective at a reasonable assurance level as of March 31, 2019.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the period covered by this Quarterly Report on Form 10-Q that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

16

Limitations on Effectiveness of Controls and Procedures

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, misstatements, errors, and instances of fraud, if any, within our Company have been or will be prevented or detected. These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of simple error or mistake. Controls also can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. We base the design of any system of controls in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, internal controls may become inadequate as a result of changes in conditions, or through the deterioration of the degree of compliance with policies or procedures.

17

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We may be subject to legal proceedings in the ordinary course of business. As of the date of this Quarterly Report on Form 10-Q, we are not aware of any legal proceedings to which we are a party that we believe could have a material adverse effect on us.

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

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, 2018. 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, 2019 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2018 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, 2019 are not necessarily indicative of the results to be expected for the full year.

Net Loss per Share

We compute basic net loss per share by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. We have other potentially dilutive securities outstanding that are not shown in a diluted net loss per share calculation because their effect in both 2019 and 2018 would be anti-dilutive. These potentially dilutive securities include stock options and warrants and totaled 3,921,048 and 3,497,424 shares at March 31, 2019 and 2018, respectively.

The following table sets forth the anti-dilutive securities excluded from diluted loss per share:

	March 31,
	2019		2018
	(Unaudited)		(Unaudited)
Anti-dilutive securities excluded from diluted loss per share:
Stock options		2,187,483		1,763,859
Warrants		1,733,565		1,733,565
Total anti-dilutive securities excluded from diluted loss per share		3,921,048		3,497,424

Recent Accounting Pronouncements

Adopted

On January 1, 2019, we adopted Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842), using a modified retrospective approach with an effective date as of January 1, 2019.  Accordingly, prior year financial statement data is presented in accordance with the previous ASC Topic 840, Leases, and no retrospective adjustments were made to the comparative periods presented.  We elected the package of practical expedients, which allowed us to carryforward our historical assessment of (1) whether contracts are or contain leases, (2) lease classification, and (3) initial direct costs.  As of January 1, 2019, we recognized an operating right-of-use asset of approximately $2.0 million and corresponding operating lease liabilities of approximately $2.2 million.  Finance lease assets were not impacted by the adoption of ASC 842, as finance lease liabilities and the corresponding assets were already recorded on the balance sheet under ASC 840.  The adoption did not materially impact our results of operations or cash flows and no cumulative adjustment to accumulated deficit was necessary as of January 1, 2019.  Refer to Note 7, Leases for additional information and enhanced disclosures related to this amended guidance.

On January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), using the full retrospective approach for all ongoing customer contracts.  Refer to Note 8, Revenue for additional information and disclosures related to this amended guidance.

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, 2020, with early adoption permitted on January 1, 2019.  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.

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.

We recorded a right-of-use operating lease asset of $2.0 million 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.  Following the Closing Date, Earth911, Inc. was subsequently renamed Quest Sustainability Services, Inc.  In addition to our investment in Earth Media Partners, LLC, we accrued a receivable in the amount of $74,298 related to the earn-out as of March 31, 2019.  The carrying amount of our investment and the accrued earn-out receivable are included in other assets.

Revolving Credit Facility

6. Revolving Credit Facility

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 and an equipment loan facility in the maximum principal amount of $2.0 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% (6.75% as of March 31, 2019), or the LIBOR lending rate for the interest period in effect, plus a margin ranging from 2.0% to 2.5% (4.85% as of March 31, 2019). The maturity date of the ABL Facility is February 24, 2022.  

We had no borrowings under the equipment loan facility, which were required to be requested no later than February 24, 2019.  

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, 2019 and 2018 was $86,742 and $84,288, respectively.  Debt issuance cost of $469,507 is being amortized to interest expense over the term of the ABL Facility beginning March 1, 2017.  As of March 31, 2019, the unamortized portion of the debt issuance costs was $273,879.  The amount of interest expense related to the amortization of the discount on the ABL Facility for the three months ended March 31, 2019 and 2018 was $23,475.  As of March 31, 2019, the ABL Facility borrowing base availability was $12,811,000 and the outstanding liability was $5,157,659, net of unamortized debt issuance cost of $273,879.

ASU 2016-02 Adoption

On January 1, 2019, we adopted ASU 2016-02, Leases (Topic 842), and the related amendments (collectively “ASC 842”).  We used the optional transition method of adoption, in which the cumulative effect of initially applying the new standard, as of January 1, 2109, 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.  Under this method of adoption, the comparative information in the condensed consolidated financial statements has not been revised and continues to be reported under the previous applicable lease accounting guidance (ASC 840).  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.

As of December 31, 2018, leases classified as capital leases under ASC 840 were included in Property and equipment, net and represented almost fully depreciated office equipment with a negligible book value.

We lease certain equipment to a customer under a lease arrangement that expires in 2020.  The capital lease receivable amounts are approximately $150,000 at March 31, 2019, the majority of which is 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, 2019 are de minimis and mature in less than 12 months.

	March 31,
	2019
Operating Leases:
Right-of-use operating lease asset:
Property and equipment, net and other assets	$	2,009,904
Lease Liabilities:
Accounts payable and accrued liabilities	$	594,642
Other long-term liabilities		1,608,946
Total operating lease liabilities	$	2,203,588

Lease Costs

For the three months ended March 31, 2019, 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 (“EDC”), 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.  

Cash paid for operating leases approximated operating lease expense and non-cash right of use asset amortization for the three months ended March 31, 2019.  We did not obtain any new operating lease right-of-use assets in the three months ended March 31, 2019.

Other Information

Our office lease had a remaining term of 3.5 years as of March 31, 2019, 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, 2019 were as follows:    

Year Ending December 31,	Amount
2019	$	476,190
2020		664,200
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.  Sales and usage-based taxes are excluded from revenue.  Three customers accounted for 59.7% of revenue for the three months ended March 31, 2019, and three customers accounted for 48.4% of revenue for the three months ended March 31, 2018.  We operate primarily in the United States, with minor services in Canada.

Revenue Type:
Services	$	24,054,519	$	22,005,572
Product sales and other		2,594,522		2,690,351
Total revenue	$	26,649,041	$	24,695,923

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, 2019 and December 31, 2018, we had $165,000 and $7,448, respectively, of deferred contract costs.  During the three months ended March 31, 2019, we amortized $53,750 and nil of deferred contract costs to selling, general, and administrative expense and as a reduction to income, respectively.  During the three months ended March 31, 2018, we amortized $33,333 and $18,069 of deferred contract costs to selling, general, and administrative expense and as a reduction to income, respectively.  

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, 2019 and December 31, 2018, we had $50,268 and $69,473, 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%.  However, we had income tax expense of $54,769 on a net operating loss for the quarter ended March 31, 2019, which is attributable to state tax obligations for states with no net operating loss carryforwards, and the continued 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, 2019 and December 31, 2018, and we had recorded a valuation allowance of $12,195,000 and $12,202,000, respectively, against deferred tax assets in excess of deferred tax liabilities in the accompanying condensed consolidated financial statements. As of March 31, 2019 and December 31, 2018, we had federal income tax net operating loss carryforwards of approximately $18,900,000, which expire at various dates ranging from 2031-2037.

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, 2018. 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, 2019 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2018 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, 2019 are not necessarily indicative of the results to be expected for the full year.

Net Loss Per Share

Net Loss per Share

We compute basic net loss per share by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. We have other potentially dilutive securities outstanding that are not shown in a diluted net loss per share calculation because their effect in both 2019 and 2018 would be anti-dilutive. These potentially dilutive securities include stock options and warrants and totaled 3,921,048 and 3,497,424 shares at March 31, 2019 and 2018, respectively.

The following table sets forth the anti-dilutive securities excluded from diluted loss per share:

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Adopted

On January 1, 2019, we adopted Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842), using a modified retrospective approach with an effective date as of January 1, 2019.  Accordingly, prior year financial statement data is presented in accordance with the previous ASC Topic 840, Leases, and no retrospective adjustments were made to the comparative periods presented.  We elected the package of practical expedients, which allowed us to carryforward our historical assessment of (1) whether contracts are or contain leases, (2) lease classification, and (3) initial direct costs.  As of January 1, 2019, we recognized an operating right-of-use asset of approximately $2.0 million and corresponding operating lease liabilities of approximately $2.2 million.  Finance lease assets were not impacted by the adoption of ASC 842, as finance lease liabilities and the corresponding assets were already recorded on the balance sheet under ASC 840.  The adoption did not materially impact our results of operations or cash flows and no cumulative adjustment to accumulated deficit was necessary as of January 1, 2019.  Refer to Note 7, Leases for additional information and enhanced disclosures related to this amended guidance.

On January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), using the full retrospective approach for all ongoing customer contracts.  Refer to Note 8, Revenue for additional information and disclosures related to this amended guidance.

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, 2020, with early adoption permitted on January 1, 2019.  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.

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.
