Disclaimer Forward-Looking Statements Advantage Solutions Inc. (the “Company”) is a provider of outsourced solutions to consumer packaged goods (“CPG”) brands and retailers. The Company’s Class A common stock is listed on the Nasdaq Global Select Market under the symbol “ADV.”  Certain statements in this presentation may be considered forward-looking statements within the meaning of the federal securities laws, including statements regarding the expected future performance of Advantage's business and projected financial results. Forward-looking statements generally relate to future events or Advantage’s future financial or operating performance. These forward-looking statements generally are identified by the words “may”, “should”, “expect”, “intend”, “will”, “would”, “could”, “estimate”, “anticipate”, “believe”, “predict”, “confident”, “potential”, “guidance”, or “continue”, or the negatives of these terms or variations of them or similar terminology. Such forward-looking statements are predictions, projections, and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from those expressed or implied by such forward-looking statements. These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by Advantage and its management at the time of such statements, are inherently uncertain. Factors that may cause actual results to differ materially from current expectations include, but are not limited to, market-driven wage changes or changes to labor laws or wage or job classification regulations, including minimum wage; developments with respect to retailers that are out of our control; the impact from tariffs; future potential pandemics or health epidemics; Advantage’s ability to continue to generate significant operating cash flow; client procurement strategies and consolidation of Advantage’s clients’ industries creating pressure on the nature and pricing of its services; consumer goods manufacturers and retailers reviewing and changing their sales, retail, marketing and technology programs and relationships; Advantage’s ability to successfully develop and maintain relevant omni-channel services for our clients in an evolving industry and to otherwise adapt to significant technological change; Advantage’s ability to maintain proper and effective internal control over financial reporting in the future; Advantage’s substantial indebtedness and our ability to refinance at favorable rates; and other risks and uncertainties set forth in the section titled “Risk Factors” in the Annual Report on Form 10-K filed by the Company with the Securities and Exchange Commission (the “SEC”) on March 3, 2026, and in its other filings made from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and Advantage assumes no obligation and does not intend to update or revise these forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. Non-GAAP Financial Measures and Related Information This presentation includes certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”), including Adjusted EBITDA, Adjusted EBITDA by Segment, Adjusted EBITDA margin, Revenues net of reimbursable expenses (“net revenues”), Net Debt, Adjusted Unlevered Free Cash Flow and Net Debt as a percentage of Last Twelve Months (“LTM”). These are not measures of financial performance calculated in accordance with GAAP and may exclude items that are significant in understanding and assessing Advantage’s financial results. Therefore, the measures are in addition to, and not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP, and should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP. You should be aware that Advantage’s presentation of these measures may not be comparable to similarly titled measures used by other companies. Reconciliations of historical non-GAAP measures to their most directly comparable GAAP counterparts are included below. Advantage believes these non-GAAP measures provide useful information to management and investors regarding certain financial and business trends relating to Advantage’s financial condition and results of operations. Advantage believes that the use of Adjusted EBITDA, Adjusted EBITDA by Segment, Adjusted EBITDA margin, Revenues net of reimbursable expenses (“net revenues”), Net Debt, Adjusted Unlevered Free Cash Flow, Net Debt as a percentage of Last Twelve Months (“LTM”) provide an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing Advantage’s financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. Non-GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures. Additionally, other companies may calculate non-GAAP measures differently, or may use other measures to calculate their financial performance, and therefore the Company's non-GAAP measures may not be directly comparable to similarly titled measures of other companies. Adjusted EBITDA consists of net loss before interest, taxes, depreciation and amortization, further adjusted for (i) non-operating income or expense and (ii) the impact of certain non-cash, nonrecurring or other items included in net (loss) income that we do not consider indicative of our ongoing operating performance, which may include acquisition and divestiture related expenses, gains and losses; stock-based compensation expenses; litigation expenses, net of recoveries on matters not representative of our ongoing business; impairments; incremental expenses on restructuring and reorganization activities associated with certain transformation programs. A full listing of adjustments to net loss are provided elsewhere in this document. Adjusted EBITDA by Segment consists of operating (loss) income by segment before interest, taxes, depreciation and amortization, further adjusted for the impact of certain non-cash, nonrecurring or other items included in net (loss) income that we do not consider indicative of our ongoing operating performance, which may include acquisition and divestiture related expenses, gains and losses; stock-based compensation expenses; litigation expenses, net of recoveries on matters not representative of our ongoing business; impairments; incremental expenses on restructuring and reorganization activities associated with certain transformation programs. A full listing of adjustments to operating income (loss) are provided elsewhere in this document.  Adjusted EBITDA Margin means Adjusted EBITDA divided by net revenues.  Revenues net of reimbursable expenses ("net revenues") and by segment means revenues less reimbursable expenses that are paid by Advantage's clients, including media, product samples, retailer fees, and other marketing and production costs. Net Debt represents the sum of current portion of long-term debt and long-term debt, less cash and cash equivalents. With respect to Net Debt, cash and cash equivalents are subtracted from the GAAP measure, total debt, because they could be used to reduce the debt obligations. We present Net Debt because we believe this non-GAAP measure provides useful information to management and investors regarding certain financial and business trends relating to the Company’s financial condition and to evaluate changes to the Company's capital structure and credit quality assessment. Adjusted Unlevered Free Cash Flow represents net cash provided by (used in) operating activities less purchase of property and equipment as disclosed in the Statements of Cash Flows further adjusted by (i) cash payments for interest, (ii) cash received from interest rate derivatives, (iii) cash paid for income taxes; (iv) cash paid for acquisition and divestiture related expenses, (v) cash paid for restructuring expenses, (vi) cash paid for reorganization expenses, including debt financing costs, (vii) cash paid for contingent earnout payments included in operating cash flow, (viii) COVID-19 benefits received, (ix) net effect of foreign currency fluctuations on cash, and (x) other adjustments that management believes are helpful in evaluating our operating performance. Adjusted Unlevered Free Cash Flow as a percentage of Adjusted EBITDA means Adjusted Unlevered Free Cash Flow divided by Adjusted EBITDA. Due to rounding, numbers presented throughout this document may not add up precisely to the totals provided and percentages may not precisely reflect the absolute figures. 2
