Use of Non-GAAP Financial Measures

Adjusted Gross Profit and Adjusted Gross Profit Margin

Adjusted Gross Profit and Adjusted Gross Profit Margin are considered non-GAAP financial measures under the rules of the U.S. Securities and Exchange Commission (the "SEC") because they exclude, respectively, certain amounts included in Gross Profit and Gross Profit Margin calculated in accordance with GAAP. Specifically, the Company calculates Adjusted Gross Profit by adding back amortization and depreciation for revenue generating activities and platform support costs to GAAP Gross Profit, the most comparable GAAP measure. Adjusted Gross Profit Margin is calculated as Adjusted Gross Profit divided by total GAAP revenue. Rubicon believes presenting Adjusted Gross Profit and Adjusted Gross Profit Margin is useful to investors because they show the progress in scaling Rubicon's digital platform by quantifying the markup and margin Rubicon charges its customers that are incremental to its marketplace vendor costs. These measures demonstrate this progress because changes in these measures are driven primarily by Rubicon's ability to optimize services for its customers, improve its hauling and recycling partners' efficiency and achieve economies of scale on both sides of the marketplace. Rubicon's management team uses these non-GAAP measures as one of the means to evaluate the profitability of Rubicon's customer accounts, exclusive of certain costs that are generally fixed in nature, and to assess how successful Rubicon is in achieving its pricing strategies. However, it is important to note that other companies, including companies in our industry, may calculate and use these measures differently or not at all, which may reduce their usefulness as a comparative measure. Further, these measures should not be read in isolation from or without reference to our results prepared in accordance with GAAP.

Adjusted EBITDA

Adjusted EBITDA is considered a non-GAAP financial measure under the rules of the SEC because it excludes certain amounts included in net loss calculated in accordance with GAAP. Specifically, the Company calculates Adjusted EBITDA by GAAP net loss adjusted to exclude interest expense and income, income tax expense and benefit, amortization and depreciation, gain or loss on extinguishment of debt obligations, equity-based compensation, phantom unit expense, gain or loss on change in fair value of warrant liabilities, gain or loss on change in fair value of earn-out liabilities, gain or loss on change in fair value of derivatives, executive severance charges, gain or loss on settlement of the management rollover bonuses, excess fair value over the consideration received for SAFE, excess fair value over the consideration received for pre-funded warrant, gain or loss on service fee settlements in connection with the Mergers, other non-operating income and expenses, and unique non-recurring income and expenses.

The Company has included Adjusted EBITDA because it is a key measure used by Rubicon's management team to evaluate its operating performance, generate future operating plans, and make strategic decisions, including those relating to operating expenses. Further, the Company believes Adjusted EBITDA is helpful in highlighting trends in Rubicon's operating results because it allows for more consistent comparisons of financial performance between periods by excluding gains and losses that are non-operational in nature or outside the control of management, as well as items that may differ significantly depending on long-term strategic decisions regarding capital structure, the tax jurisdictions in which Rubicon operates and capital investments. Adjusted EBITDA is also often used by analysts, investors and other interested parties in evaluating and comparing Rubicon's results to other companies within the industry. Accordingly, the Company believes that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating its operating results in the same manner as Rubicon's management team and board of directors.

Adjusted EBITDA has limitations as an analytical tool, and it should not be considered in isolation or as a substitute for analysis of net loss or other results as reported under GAAP. Some of these limitations are:

	●	Adjusted EBITDA does not reflect the Company's cash expenditures, future requirements for capital expenditures, or contractual commitments;

	●	Adjusted EBITDA does not reflect changes in, or cash requirements for, the Company's working capital needs;

	●	Adjusted EBITDA does not reflect the Company's tax expense or the cash requirements to pay taxes;

	●	although amortization and depreciation are non-cash charges, the assets being amortized and depreciated will often have to be replaced in the future and Adjusted EBITDA does not reflect any cash requirements for such replacements;

	●	Adjusted EBITDA should not be construed as an inference that the Company's future results will be unaffected by unusual or non-recurring items for which the Company may make adjustments in historical periods; and

	●	other companies in the industry may calculate Adjusted EBITDA differently than the Company does, limiting its usefulness as a comparative measure.
