Preliminary Results for the Year Ended December 31, 2025

Advantage Solutions Inc. (referred to herein as “we”) have presented below certain preliminary financial data, prepared by our management, representing our estimates for the year ended December 31, 2025. We are in the process of finalizing our financial data as of and for the year ended December 31, 2025. The preliminary estimates are based on currently available information and do not present all information necessary for an understanding of our financial data as of and for the year ended December 31, 2025. We have provided ranges for certain financial data, rather than specific amounts, because these results are preliminary and subject to change.

As of the date hereof, we have not yet completed the preparation of our financial statements as of and for the year ended December 31, 2025. Although our management is currently unaware of any items that would require us to make adjustments to the information set forth below, it is possible that our management may identify such items as we complete our financial statements and any resulting changes could be material. Accordingly, undue reliance should not be placed on these preliminary estimates. These preliminary estimates are forward-looking statements, not necessarily indicative of any future period, and should be read together with the sections titled “Risk Factors” and “Forward-Looking Statements,” and our consolidated financial statements and related notes in our Annual Report on Form 10-K for the year ended December 31, 2024.

We estimate that revenues for the year ended December 31, 2025 will be between $3,500 million and $3,550 million, a decrease of 1%, assuming the midpoint of the range, compared to the year ended December 31, 2024.

We estimate that operating loss from continuing operations for the year ended December 31, 2025 will be between $130 million and $120 million, a decrease of 58%, assuming the midpoint of the range, compared to the year ended December 31, 2024.

We estimate that Adjusted EBITDA from Continuing Operations will be between $328 million and $333 million, a decrease of 7%, assuming the midpoint of the range, compared to the year ended December 31, 2024.

The table below presents our preliminary estimated revenues, operating loss from continuing operations and Adjusted EBITDA from Continuing Operations for the year ended December 31, 2025 and revenues, operating loss from continuing operations and Adjusted EBITDA from Continuing Operations for the years ended December 31, 2024 and December 31, 2023:


	Year Ended December 31,					Year Ended December 31, 2025						Year Ended December 31, 2025 vs. Year Ended December 31, 2024^(a)

(a)	Calculated based on the average of the low and high estimates for year ended December 31, 2025.

We are unable to reconcile the preliminary ranges of Adjusted EBITDA from Continuing Operations to net (loss) income, the most directly comparable GAAP measure, without unreasonable efforts because we have not completed our evaluation of the impact of discrete events on income tax expense for the year ended December 31, 2025 and, as a consequence, we are unable to estimate our income tax expense for the period. The variability of income tax expense could have a significant impact on our reported financial results. The table below provides a midpoint reconciliation of Adjusted EBITDA from Continuing Operations to operating loss from continuing operations, the nearest available GAAP measure:
