Item 5.07. Submission of Matters to a Vote of Security Holders.

As previously disclosed, on April 26, 2024, U.S. Silica Holdings, Inc. (the “Company”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Star Holding LLC, a Delaware limited liability company (“Parent”), and Star Merger Co., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), pursuant to which, among other things, and subject to the terms and conditions set forth therein, Merger Sub will merge with and into the Company, with the Company surviving the Merger as a wholly owned subsidiary of Parent (the “Merger”). Parent and Merger Sub are affiliates of certain funds managed by affiliates of Apollo Global Management, Inc.

On July 16, 2024, the Company held a virtual special meeting of stockholders (the “Special Meeting”) to consider certain proposals related to the Merger Agreement. All references in this Current Report on Form 8-K to “present in person” shall mean virtually present at the Special Meeting.

As of the close of business on June 10, 2024, the record date for the Special Meeting, there were 78,204,596 shares of the Company’s common stock, par value $0.01 per share (the “Shares”), outstanding and entitled to vote at the Special Meeting. A total of 61,015,716 Shares, representing approximately 78.02% of the voting power of the outstanding Shares entitled to vote, were present in person or represented by proxy at the Special Meeting, constituting a quorum to conduct business.

At the Special Meeting, the following proposals were considered:

1. Merger Proposal. A proposal to approve and adopt the Merger Agreement (the “Merger Proposal”).

2. Merger Compensation Proposal. A proposal to approve, by a non-binding, advisory vote, the compensation that may be paid or become payable to the Company’s named executive officers in connection with the Merger (the “Merger Compensation Proposal”).

3. Adjournment Proposal. One or more proposals to adjourn the Special Meeting to a later date or dates, if necessary or appropriate, including adjournments to solicit additional proxies if there are insufficient votes at the time of the Special Meeting to approve the Merger Proposal or in the absence of a quorum (the “Adjournment Proposal”).

Each proposal is described in detail in the Company’s definitive proxy statement filed with the Securities and Exchange Commission on June 11, 2024, as supplemented on July 8, 2024. The Merger Proposal, the Merger Compensation Proposal and the Adjournment Proposal were each approved by the requisite vote of the Company’s stockholders. The final voting results for each proposal are described below.
