#### Item 5.07 Submission of Matters to a Vote of Security Holders.
On March 16, 2026, Advantage Solutions Inc. (the "Company," or "we" or "us") held a special meeting of stockholders (the "Special Meeting"). A total of 291,349,131 shares of the Company's common stock, par value $0.0001 (the "Common Stock"), were present in person or represented by proxy at the Special Meeting, representing approximately 89% of the Common Stock outstanding as of the February 6, 2026 record date. Following are the voting results for the proposals considered and voted upon at the Special Meeting, each of which were described in the Company's Definitive Proxy Statement filed with the Securities and Exchange Commission ("SEC") on February 13, 2026.

Proposal 1 - Approve amendments to the Company's Third Amended and Restated Certificate of Incorporation to effect a reverse stock split of the Company's Class A common stock, par value $0.0001 per share ("Common Stock"), at a ratio ranging from any whole number between 1-for-10 to 1-for-25, inclusive, with such ratio to be determined at the discretion of the Company's Board of Directors ("Board"), and reduce the number of authorized shares of Common Stock and unissued authorized shares of the Company's preferred stock, no par value, subject to the Board's authority to determine when to file the amendment and to abandon the other amendments notwithstanding prior stockholder approval of such amendments.

Proposal 2 - Approval of an adjournment of the Special Meeting, if necessary, to solicit additional proxies if there are not sufficient votes at the time of the Special Meeting to approve Proposal 1.

---

Based on the foregoing votes, both Proposal 1 and Proposal 2 were approved. Although Proposal 2 was approved, adjournment of the Special Meeting was not necessary because the Company's stockholders approved Proposal 1.

#### Item 7.01 Regulation FD Disclosure.
Following the Special Meeting, the Board approved a 1-for-25 reverse stock split (the "Reverse Stock Split") of the Company's Common Stock.

The Reverse Stock Split is expected to become effective on March 26, 2026 at 5:00 p.m. ET (the "Effective Time"), with the Company's Common Stock to begin trading on a split-adjusted basis at market open on March 27, 2026 under the existing symbol "ADV" and new CUSIP number 00791N 201. In connection with the Reverse Stock Split, every 25 shares of the Company's Common Stock issued and outstanding as of the Effective Time will be automatically converted into one share of Common Stock. No fractional shares will be issued in connection with the Reverse Stock Split. Instead, each stockholder will be entitled to receive a cash payment in lieu thereof at a price equal to the fraction of one share to which the stockholder would otherwise be entitled multiplied by the closing price per share of Common Stock on the Nasdaq Global Select Market on March 26, 2026.

As a result of the Reverse Stock Split, proportionate adjustments will be made to the number of shares of Common Stock underlying the Company's outstanding equity awards and shares issuable under the Company's equity incentive plans and existing agreements, as well as the exercise price, as applicable.

The information in this Item 7.01 of this Current Report on Form 8-K, is furnished herewith and shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to the liabilities under that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language in such filing.
