QUEST RESOURCE HOLDING CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. The Company, Description of Business, and Liquidity

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”), and 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.  

Liquidity – As of March 31, 2018 and December 31, 2017, our working capital balance was $2,578,248 and $4,243,990, respectively.

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, 2017. 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, 2018 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2017 condensed consolidated balance sheet data from audited financial statements; however, we did not include all disclosures required by GAAP. As 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, 2018 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 2018 and 2017 would be anti-dilutive. These potentially dilutive securities include stock options and warrants and totaled 3,497,424 and 3,313,907 shares at March 31, 2018 and 2017, respectively.

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

	March 31,
	2018		2017
	(Unaudited)		(Unaudited)
Anti-dilutive securities excluded from diluted loss per share:
Stock options		1,763,859		1,375,216
Warrants		1,733,565		1,938,691
Total anti-dilutive securities excluded from diluted loss per share		3,497,424		3,313,907

Recent Accounting Pronouncements

Adopted

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). On January 1, 2018, we adopted ASU 2014-09 using the full retrospective approach for

6

all ongoing customer contracts.  There was no impact to our financial statements as a result of adopting Topic 606 for the three months ended March 31, 2018 and 2017.  See Note 8 for additional information and disclosures related to this amended guidance.

Pending Adoption

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842).  The update improves financial reporting about leasing transactions by requiring a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are still evaluating the impact of adopting ASU 2016-02 on our consolidated financial statements. However, given the material amount of our future minimum payments under non-cancellable operating leases, primarily office rent, at March 31, 2018, we expect to recognize a material right-of-use lease asset and lease liability upon adoption of the ASU.

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, 2018 and December 31, 2017, property and equipment, net, and other assets consisted of the following:

	March 31,		December 31,
	2018		2017
	(Unaudited)
Property and equipment, net of accumulated depreciation of $2,296,541      and $2,193,231 as of March 31, 2018 and December 31, 2017,      respectively	$	862,924	$	956,867
Security deposits and other assets		481,275		363,475
Property and equipment, net, and other assets	$	1,344,199	$	1,320,342

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, 2018 was $103,310, inclusive of $45,296 of depreciation expense reflected within “Cost of revenue” in our condensed consolidated statement of operations as it related to assets used in directly servicing customer contracts.  Depreciation expense for the three months ended March 31, 2017 was $115,246, inclusive of $41,075 of depreciation expense reflected within “Cost of revenue.”  At March 31, 2018, the carrying value of our capital lease assets was $217,729, net of $282,368 of accumulated depreciation. At December 31, 2017, the carrying value of our capital lease assets was $243,778, net of $256,319 of accumulated depreciation.

On February 20, 2018 (“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 revenues, and accounts receivable as of 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 $8,086 related to the earn-out as of March 31, 2018.  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

8

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 agreement, plus a margin ranging from 1.0% to 1.5% (6.25% as of March 31, 2018), or the LIBOR lending rate for the interest period in effect, plus a margin ranging from 2.0% to 2.5% (4.28% as of March 31, 2018). The maturity date of the revolving credit facility is February 24, 2022.  

Loans under the equipment loan facility may be requested at any time until February 24, 2019. Each loan under the equipment loan facility bears interest, at our option, at either the Base Rate, as defined in the agreement, plus 2.00%, or the LIBOR lending rate for the interest period in effect, plus 3.00%. The maturity date of the equipment loan facility is February 24, 2022.

The ABL Facility contains certain specific financial covenants regarding a minimum liquidity requirement and a minimum fixed charge coverage ratio. The minimum fixed charge coverage ratio covenant applies commencing May 15, 2018, when the trailing 12-month period ending March 31, 2018 is reported. 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, 2018 and 2017 was $84,288 and $110,381, respectively.  Debt issuance cost of $469,507 is being amortized to interest expense over the life of the new revolving credit facility beginning March 1, 2017.  As of March 31, 2018, the unamortized portion of the debt issuance costs was $367,781.  The amount of interest expense related to the amortization of the discount on the revolving credit facility for the three months ended March 31, 2018 was $23,475.  As of March 31, 2018, the ABL Facility borrowing base availability was $11,545,000 and the outstanding liability was $5,100,957, net of unamortized debt issuance cost of $367,781. There were no draws made on the equipment loan facility as of March 31, 2018.

7. Capital Lease Obligations

At March 31, 2018 and December 31, 2017, total capital lease obligations outstanding consisted of the following:

	March 31,			December 31,
	2018			2017

Total		28,701			41,664
Less: current maturities		(27,132	)		(39,067	)
Long-term portion	$	1,569		$	2,597

Our capital lease obligations are included within “Deferred revenue and other current liabilities” and “Other long-term liabilities” in our condensed consolidated balance sheets.  The amount of interest expense related to our capital leases for the three months ended March 31, 2018 and 2017 was $618 and $2,462, respectively.

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, revenue is recognized as waste and recyclable material is collected or when products are delivered.  

We generally recognize revenues 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 previously had a contract accounted for as a net basis management fee contract, with revenue of $44,088 and gross billings of $1,294,459 for the three months ended March 31, 2017. This management fee contract ended in the second quarter of 2017, and we currently have no other net basis contracts.  

9

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 48.4% of revenue for the three months ended March 31, 2018, and two customers accounted for 55.1% of revenue for the three months ended March 31, 2017.  We operate primarily in the United States, with minor services in Canada.

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.  Our contract acquisition costs are classified 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, 2018 and December 31, 2017, we had $199,736  and $136,139, respectively, of deferred contract costs.  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.  During the three months ended March 31, 2017, we amortized $100,000 and $18,069 of deferred contract costs to selling, general and administrative expense and as a reduction to income, respectively.

Certain customers are billed in advance, and, accordingly, recognition of related revenues is deferred as a contract liability until the services are provided and control transferred to the customer.  As of March 31, 2018 and December 31, 2017, we had $142,389 and $309,089, respectively, of deferred revenue, the majority of which was classified in “Deferred revenue and other current liabilities.”

9. Income Taxes

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 for the amount of deferred tax assets that, based on available evidence, are more likely than not to be realized. Realization of our net operating loss carryforward was not reasonably assured as of March 31, 2018 and December 31, 2017, and we have recorded a valuation allowance of $12,800,000 and $12,150,000, respectively, against deferred tax assets in excess of deferred tax liabilities in the accompanying condensed consolidated financial statements. As of March 31, 2018 and December 31, 2017, we had federal income tax net operating loss carryforwards of approximately $20,200,000 and $19,700,000, respectively, which expire at various dates beginning in 2031.

On December 22, 2017, The Tax Cuts and Jobs Act (the “2017 Act”) was enacted. The most significant impact to us of the 2017 Act was a decrease in the federal corporate income tax rate from 35% to 21% starting in 2018.

10. Fair Value of Financial Instruments

Our financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, deferred revenue, revolving credit facility, and capital lease obligations. 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 long-term portions of capital lease obligations and revolving credit 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 includes 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 includes 200,000,000 shares of common stock with a par value of $0.001, of which 15,302,455 shares were issued and outstanding as of March 31, 2018 and December 31, 2017.

Warrants – At March 31, 2018, we had outstanding exercisable warrants to purchase 1,733,565 shares of common stock.

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, 2018 compared to Three Months Ended March 31, 2017

Revenue

For the quarter ended March 31, 2018, revenue was $24.7 million, a decrease of $17.8 million, or 42.0%, compared with $42.5 million for the quarter ended March 31, 2017.  As part of our strategic plan, we took actions during 2017 to transition our business to deliver improved operational and financial performance, which included making sustainable improvements to our procurement processes, as well as taking a disciplined approach to customer acquisition and renewal.  Primarily as a result of changes in our mix of services and reductions of services with certain customers in the latter half of 2017, we experienced an overall decrease in revenue for the quarter

12

ended March 31, 2018 relative to 2017, which was partially offset by increased service revenue from the continuing and new customer base.  This quarter-over-quarter decrease in revenue was partially offset by a net decrease in cost of sales, resulting in a higher gross margin percentage in the first quarter of 2018 relative to 2017.

Cost of Revenue/Gross Profit

Cost of revenue decreased $17.2 million to $21.1 million for the quarter ended March 31, 2018 from $38.3 million for the quarter ended March 31, 2017.  The decrease was primarily due to the changes in our mix of services, decreased cost of certain contracted services, and reductions of services with certain customers, partially offset by increased services from the continuing and new customer base.

Gross profit decreased $638,000 to $3.5 million for the quarter ended March 31, 2018 from $4.2 million for the quarter ended March 31, 2017.  Gross margin was 14.4% of first quarter 2018 revenue compared with 9.8% of first quarter 2017 revenue.  The decrease in gross profit and increase in gross margin percentage for the three months ended March 31, 2018 was primarily due to the net effect of reductions of services with certain customers, the overall lower cost of subcontracted services, and the exiting of lower margin services with certain customers.

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

Operating Expenses

Operating expenses were $4.7 million and $5.9 million for the three months ended March 31, 2018 and 2017, respectively, a decrease of $1.2 million.  

Selling, general, and administrative expenses were $3.7 million and $4.9 million for the three months ended March 31, 2018 and 2017, respectively, a decrease of approximately $1.2 million. The decrease was primarily related to a decrease in stock related compensation of $390,000, labor related expenses of approximately $330,000, and severance costs of $248,000.  

Operating expenses also included depreciation and amortization of $985,000 and $1.0 million for the three months ended March 31, 2018 and 2017, respectively.  

Interest Expense

For the three months ended March 31, 2018, interest expense increased by $10,000 to $124,000 from $114,000 for the three months ended March 31, 2017.  See Note 6 to our condensed consolidated financial statements for a discussion of our revolving credit facility.

Net Loss

Net loss for the quarter ended March 31, 2018 was $1.3 million compared with a net loss of $1.9 million for the quarter ended March 31, 2017.  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, may vary from period to period depending on commodity prices, the blend of services, the nature of the contracts, and sales volumes.

Loss per Share

Net loss per basic and diluted share was $(0.09) for the quarter ended March 31, 2018 compared with a net loss per basic and diluted share of $(0.13) for the quarter ended March 31, 2017. The weighted average number of shares of common stock outstanding increased to 15.3 million for the three months ended March 31, 2018 from slightly under 15.3 million shares for the three months ended March 31, 2017.  

The increase in the share count for the three months ended March 31, 2018 was primarily from the issuance of shares for Employee Stock Purchase Plan options exercised during 2017.

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,” 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. 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, 2018, other adjustments include legal fees related to our sale of certain Earth911 assets and aggregated $48,845.  For the three months ended March 31, 2017, other adjustments of $244,371 included certain severance costs.

The following table reflects Adjusted EBITDA for the three months ended March 31, 2018 and 2017:

Adjusted EBITDA	$	114,331		$	105,368

Liquidity and Capital Resources

As of March 31, 2018 and December 31, 2017, we had $1.1 million in cash and cash equivalents. Working capital was $2.6 million as of March 31, 2018 compared with $4.2 million as of December 31, 2017.

We derive our primary sources of funds for conducting our business activities from sales of services, commodities, and consulting; borrowings under our credit facilities; and the placement of our equity securities with 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 $1.1 million, our borrowing capacity under our $20.0 million credit facility (which was $11.5 million as of March 31, 2018), 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 equity capital markets with placements of our securities.

Cash Flows

The following discussion relates to the major components of our cash flows for the three months ended March 31, 2018 and 2017.

Cash Flows from Operating Activities

Net cash provided by operating activities was $1.8 million for the three months ended March 31, 2018 compared with net cash used in operating activities of $2.1 million for the three months ended March 31, 2017.

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

• 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.

Net cash used in operating activities for the three months ended March 31, 2017 related primarily to the net effect of the following:

• net loss of $1.9 million;

• offset by non-cash items of $1.8 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 $2.0 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.

14

Cash Flows from Investing Activities

Cash used in investing activities for the three months ended March 31, 2018 and 2017 was $60,000 and $109,000, respectively, primarily from purchases of property and equipment and costs related to software development.  

Cash Flows from Financing Activities

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.  Cash provided by financing activities was $3.0 million for the three months ended March 31, 2017, primarily from net draws from our revolving credit facility.  See Note 6 to our condensed consolidated financial statements for a discussion of our asset-based revolving credit facility entered into in February 2017.

Inflation

We do not believe that inflation had a material impact on us during the three months ended March 31, 2018 and 2017.

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, long-lived assets, 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 2017 Annual Report.  There have been no changes in our critical accounting policies during the first three months of 2018.

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 the reasonable assurance level as of March 31, 2018.

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.

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

15

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.

16

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.

Item 1A. Risk Factors

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, 2017. 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, 2018 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2017 condensed consolidated balance sheet data from audited financial statements; however, we did not include all disclosures required by GAAP. As 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, 2018 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 2018 and 2017 would be anti-dilutive. These potentially dilutive securities include stock options and warrants and totaled 3,497,424 and 3,313,907 shares at March 31, 2018 and 2017, respectively.

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

	March 31,
	2018		2017
	(Unaudited)		(Unaudited)
Anti-dilutive securities excluded from diluted loss per share:
Stock options		1,763,859		1,375,216
Warrants		1,733,565		1,938,691
Total anti-dilutive securities excluded from diluted loss per share		3,497,424		3,313,907

Recent Accounting Pronouncements

Adopted

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). On January 1, 2018, we adopted ASU 2014-09 using the full retrospective approach for all ongoing customer contracts.  There was no impact to our financial statements as a result of adopting Topic 606 for the three months ended March 31, 2018 and 2017.  See Note 8 for additional information and disclosures related to this amended guidance.

Pending Adoption

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842).  The update improves financial reporting about leasing transactions by requiring a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are still evaluating the impact of adopting ASU 2016-02 on our consolidated financial statements. However, given the material amount of our future minimum payments under non-cancellable operating leases, primarily office rent, at March 31, 2018, we expect to recognize a material right-of-use lease asset and lease liability upon adoption of the ASU.

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.

At December 31, 2017, the carrying value of our capital lease assets was $243,778, net of $256,319 of accumulated depreciation.

On February 20, 2018 (“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 revenues, and accounts receivable as of 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 $8,086 related to the earn-out as of March 31, 2018.  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 agreement, plus a margin ranging from 1.0% to 1.5% (6.25% as of March 31, 2018), or the LIBOR lending rate for the interest period in effect, plus a margin ranging from 2.0% to 2.5% (4.28% as of March 31, 2018). The maturity date of the revolving credit facility is February 24, 2022.  

Loans under the equipment loan facility may be requested at any time until February 24, 2019. Each loan under the equipment loan facility bears interest, at our option, at either the Base Rate, as defined in the agreement, plus 2.00%, or the LIBOR lending rate for the interest period in effect, plus 3.00%. The maturity date of the equipment loan facility is February 24, 2022.

The ABL Facility contains certain specific financial covenants regarding a minimum liquidity requirement and a minimum fixed charge coverage ratio. The minimum fixed charge coverage ratio covenant applies commencing May 15, 2018, when the trailing 12-month period ending March 31, 2018 is reported. 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, 2018 and 2017 was $84,288 and $110,381, respectively.  Debt issuance cost of $469,507 is being amortized to interest expense over the life of the new revolving credit facility beginning March 1, 2017.  As of March 31, 2018, the unamortized portion of the debt issuance costs was $367,781.  The amount of interest expense related to the amortization of the discount on the revolving credit facility for the three months ended March 31, 2018 was $23,475.  As of March 31, 2018, the ABL Facility borrowing base availability was $11,545,000 and the outstanding liability was $5,100,957, net of unamortized debt issuance cost of $367,781. There were no draws made on the equipment loan facility as of March 31, 2018.

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, revenue is recognized as waste and recyclable material is collected or when products are delivered.  

We generally recognize revenues 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 previously had a contract accounted for as a net basis management fee contract, with revenue of $44,088 and gross billings of $1,294,459 for the three months ended March 31, 2017. This management fee contract ended in the second quarter of 2017, and we currently have no other net basis contracts.  

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 48.4% of revenue for the three months ended March 31, 2018, and two customers accounted for 55.1% of revenue for the three months ended March 31, 2017.  We operate primarily in the United States, with minor services in Canada.

	March 31,
	2018		2017
	(Unaudited)		(Unaudited)
Revenue Type:
Services	$	22,005,572	$	39,835,675
Product sales and other		2,690,351		2,704,147
Total Revenue	$	24,695,923	$	42,539,822

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.  Our contract acquisition costs are classified 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, 2018 and December 31, 2017, we had $199,736  and $136,139, respectively, of deferred contract costs.  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.  During the three months ended March 31, 2017, we amortized $100,000 and $18,069 of deferred contract costs to selling, general and administrative expense and as a reduction to income, respectively.

Certain customers are billed in advance, and, accordingly, recognition of related revenues is deferred as a contract liability until the services are provided and control transferred to the customer.  As of March 31, 2018 and December 31, 2017, we had $142,389 and $309,089, respectively, of deferred revenue, the majority of which was classified in “Deferred revenue and other current liabilities.”

Income Taxes

9. Income Taxes

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 for the amount of deferred tax assets that, based on available evidence, are more likely than not to be realized. Realization of our net operating loss carryforward was not reasonably assured as of March 31, 2018 and December 31, 2017, and we have recorded a valuation allowance of $12,800,000 and $12,150,000, respectively, against deferred tax assets in excess of deferred tax liabilities in the accompanying condensed consolidated financial statements. As of March 31, 2018 and December 31, 2017, we had federal income tax net operating loss carryforwards of approximately $20,200,000 and $19,700,000, respectively, which expire at various dates beginning in 2031.

On December 22, 2017, The Tax Cuts and Jobs Act (the “2017 Act”) was enacted. The most significant impact to us of the 2017 Act was a decrease in the federal corporate income tax rate from 35% to 21% starting in 2018.

10. Fair Value of Financial Instruments

Our financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, deferred revenue, revolving credit facility, and capital lease obligations. 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 long-term portions of capital lease obligations and revolving credit facility, based on borrowing rates currently available to us for loans with similar terms and maturities.

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, 2017. 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, 2018 and the results of our operations and cash flows for the periods presented. We derived the December 31, 2017 condensed consolidated balance sheet data from audited financial statements; however, we did not include all disclosures required by GAAP. As 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, 2018 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 2018 and 2017 would be anti-dilutive. These potentially dilutive securities include stock options and warrants and totaled 3,497,424 and 3,313,907 shares at March 31, 2018 and 2017, respectively.

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

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Adopted

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). On January 1, 2018, we adopted ASU 2014-09 using the full retrospective approach for all ongoing customer contracts.  There was no impact to our financial statements as a result of adopting Topic 606 for the three months ended March 31, 2018 and 2017.  See Note 8 for additional information and disclosures related to this amended guidance.

Pending Adoption

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842).  The update improves financial reporting about leasing transactions by requiring a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are still evaluating the impact of adopting ASU 2016-02 on our consolidated financial statements. However, given the material amount of our future minimum payments under non-cancellable operating leases, primarily office rent, at March 31, 2018, we expect to recognize a material right-of-use lease asset and lease liability upon adoption of the ASU.

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.
