ADVANTAGE SOLUTIONS Q4 and FY 2020 Earnings Presentation March 16, 2021

DISCLAIMER Forward Looking Statements Certain statements in this presentation or accompanying commentary may be considered forward-looking statements with the meaning of federal securities laws. Forward-looking statements generally relate to future events or Advantage's future financial or operating performance, In some cases, you can identify forward-looking statements by terminology such as "may", "should", "expect", "intend", "will", "would", "estimate", "anticipate", "believe", "predict", "potential" 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 are inherently uncertain. Factors that may cause actual results to differ materially from current expectations include, but are not limited to, the COVID-19 pandemic and the measures taken in response thereto; changes to labor laws or wage or job classification regulations, including minimum wage, or other market-driven wage changes; 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 effectively remediate material weaknesses and maintain proper and effective internal controls in the future; potential and actual harms to Advantage's business arising from the Take 5 Matter; Advantage's substantial indebtedness and our ability to refinance at favorable rates; and other risks, uncertainties and assumptions that are difficult to predict, including those more fully described in our most recent annual report on Form 10-K and any subsequent periodic reports on Form 10-Q and current reports on Form 8-K. 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 Measure and Related Information This presentation includes certain financial measures not presented in accordance with generally accepted accounting principles ("GAAP") including Adjusted EBITDA and Adjusted Net Income. These non-GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing the Company's financial results. Therefore, these 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 the Company's presentation of these measures may not be comparable to similarly-titled measures used by other companies. The Company believes these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company's financial condition and results of operations. The Company believes that the use of Adjusted EBITDA and Adjusted Net Income provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing the Company's financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. These 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. Adjusted EBITDA means net income (loss) before (i) interest expense, net, (ii) (benefit from) provision for income taxes, (iii) depreciation, (iv) impairment of goodwill and indefinite-lived assets, (v) amortization of intangible assets, (vi) private equity sponsors' management fees and equity-based compensation expense, (vii) fair value adjustments of contingent consideration related to acquisitions, (viii) acquisition-related expenses, (ix) costs associated with COVID-19, net of benefits received, (x) EBITDA for economic interests in investments, (xi) restructuring expenses, (xii) litigation expenses, (xiii) (Recovery from) loss on Take 5, (xiv) costs associated with the Take 5 Matter and (xv) other adjustments that management believes are helpful in evaluating its operating performance. Adjusted Net Income means net (loss) income before (i) impairment of goodwill and indefinite-lived assets, (ii) amortization of intangible assets, (iii) private equity sponsors' management fees and equity-based compensation expense, (iv) fair value adjustments of contingent consideration related to acquisitions, (v) acquisition-related expenses, (vi) costs associated with COVID-19, net of benefits received, (vii) EBITDA for economic interests in investments, (viii) restructuring expenses, (ix) litigation expenses, (x) (Recovery from) loss on Take 5, (xi) deferred financing fees, (xii) costs associated with the Take 5 Matter, (xiii) other adjustments that management believes are helpful in evaluating our operating performance, and (xiv) related tax adjustments. 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. 1

FISCAL YEAR 2021 OUTLOOK Revised FY 2021 Outlook (excluding future acquisitions): Expecting COVID-related restrictions to continue through the first half of 2021 as vaccines are rolled out and COVID continues to limit activity FY 2021 Adjusted EBITDA of $515 to $525 million, an increase to the $515 million forecast shared as part of our business combination Revenues likely to improve versus 2020 as the year progresses Revenues likely to be suppressed in the first half due to the mix of activity as we continue to nimbly manage through COVID (expect less zero-margin passthrough revenue in the first half due to a lower mix of in-person sampling events), but expecting improvement through the second half as in-store sampling returns to full operation Expect first quarter to be a tough comp since COVID did not begin to materially affect our operations until activity restrictions were introduced in the United States in the month of March Marketing expected to be down versus prior year because of COVID impact to in-store sampling business Sales expected to comp favorably in January and February against pre-COVID 2020 periods, but pantry-loading in March of 2020 will be tough comp and partially offsetting Net Debt / Adjusted EBITDA to be below 4x by the end of 2021 with continued de-leveraging towards 3x over time 11
