QUEST RESOURCE HOLDING CORPORATION AND SUBSIDIARIES

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

On December 7, 2021, Rome Holdings, LLC and M&A Business Consulting, Inc. (collectively, the “Sellers”) entered into a membership interest purchase agreement (the “MIPA”) by and among Quest Sustainability Services, Inc. (“Buyer”) (QSSI), a wholly-owned subsidiary of the Company, RWS Facility Services, LLC (the “Business”) (RWS) and completed the acquisition by Buyer of the Business as set forth in the MIPA. Whereas, Sellers collectively owned (100%) of all of the issued and outstanding membership interest of the Business, which is a full-service management company engaged in the brokering of recycling, waste and sustainability solutions, located in Chadds Ford, PA.

As consideration for the Acquisition, under the MIPA, the Seller received a purchase price of $33,000,000 in cash subject to certain adjustments set forth in the MIPA at the closing of the Acquisition.

As of the date of acquisition, the total value of the purchase was estimated to be $34,013,000. The net tangible assets acquired had a value of $1,721,000 with the remainder of the purchase price, $32,292,000, allocated by the appraiser to intangible assets as follows: customer relationships - $24,590,000, trademark $760,000, non-compete $40,000 and the remainder associated with cost-in-excess of these assets, or goodwill, of $6,902,000. It was estimated that customer relationships, trademark and the non-compete would have an estimated life of five (5) years, seven (7) years and three (3) years, respectively. ▇▇▇▇▇▇▇▇ would be subject to impairment valuations periodically in accordance with accounting principles generally accepted in the United States and other authoritative literature associated with goodwill impairment.

In order to facilitate the purchase of RWS, Buyer, and certain of its domestic subsidiaries modified an existing credit agreement, originally dated as of October 19, 2020, with Monroe Capital. Among other things, the modified Credit Agreement provides for a senior secured term loan facility in the principal amount of $34.7 million. The senior secured term loan at the LIBOR Rate for LIBOR Loans plus the Applicable Margin (as defined); provided, that if the provision of LIBOR Loans becomes unlawful or unavailable, then interest will be payable at a rate per annum equal to the Base Rate (as defined) from time to time in effect plus the Applicable Margin for Base Rate Loans (as defined). The maturity date of the revolving credit facility is October 19, 2025 (the "Maturity Date"). The senior secured term loan will amortize in aggregate annual amounts equal to 1.00% of the original principal amount of the senior secured term loan facility with the balance payable on the Maturity Date. Proceeds of the senior secured term loan were permitted to be used in connection with the Acquisition.

The following unaudited pro forma condensed combined financial information present the historical condensed combined financial information of QRHC and Subsidiaries and RWS, after giving effect to the Acquisition. The acquisition was accounted for under the purchase method of accounting in accordance with the Financial Accounting Standards Board’s Accounting Standards Codification Topic 805, Business Combinations (“ASC 805”), with the excess purchase price over the fair value of the assets acquired and liabilities assumed allocated to goodwill.

The fair value of assets acquired and liabilities assumed was based upon a preliminary valuation and the Company’s estimates and assumptions are subject to change within the measurement period. The estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates.

The unaudited pro forma condensed combined financial information is presented for informational purposes only and is not necessarily indicative of the operating results or financial position that would have occurred if the Acquisition had been affected on the dates previously set forth, nor is it indicative of the future operating results or financial position in combination.

The unaudited pro forma condensed combined balance sheet shown on these unaudited pro forma statements is based upon the historical figures for all of the combined entities at September 30, 2021, as if the acquisition had taken place on the balance sheet date. The unaudited pro forma condensed combined statements of operations for the nine months ended September 30, 2021 and year ended December 31, 2020, assumes the acquisition took place on the first day of the fiscal year. The unaudited pro forma condensed combined financial statements may not be indicative of the actual results of the acquisition and merger of the operations. In particular, the unaudited pro forma condensed combined financial statements are based upon management’s current estimate of the allocation of the purchase price, the final allocation of which may differ.

The accompanying unaudited pro forma condensed combined financial statements should be read in connection with the historical financial statements of QRHC and RWS (under Rome Holdings, LLC), including the related notes and other financial information included in the filing. Management adjustments are, in the opinion of management, necessary to a fair statement of pro forma financial information presented.
