Submission of Stockholder Proposals and Nominations for the 2027 Annual Meeting

In order for a stockholder proposal to be considered for inclusion in the Company’s Proxy Statement for the 2027 Annual Meeting pursuant to Rule 14a-8 under the Exchange Act, our Corporate Secretary must receive the proposal no later than November 13, 2026. Such proposals must be sent via registered, certified, or express mail (or other means that allows the stockholder to determine when the proposal was received) to: Drilling Tools International Corporation, 10370 Richmond Avenue, Suite 1000, Houston, TX 77042, Attention: Investor Relations. Such proposals must comply with the SEC’s requirements in Rule 14a-8 under the Exchange Act regarding the inclusion of stockholder proposals in Company-sponsored proxy materials, such as the requirement that the stockholder continues to own a minimum number of shares until the 2027 Annual Meeting and appear in person or through an authorized representative at the 2027 Annual Meeting to present the proposal.

Alternatively, stockholders intending to put forth a director nomination or a stockholder proposal not pursuant to Rule 14a-8 under the Exchange Act must comply with the requirements set forth in our Bylaws. Our Bylaws require, among other things, that our Corporate Secretary receive written notice with respect to each director nomination or other proposal that the stockholder intends to present at the 2027 Annual Meeting from the stockholder no earlier than the close of business on December 29, 2026 and no later than the close of business on January 28, 2027. The notice must contain the information required by our Bylaws. In order for stockholders to give timely notice of nominations for directors, other than those nominated by the Company, for inclusion on a universal proxy card in connection with the 2027 Annual Meeting, notice must be submitted no later than February 27, 2027 and include all of the information required by Rule 14a-19 under the Exchange Act.

Proposals received after the dates mentioned will not be included in the proxy statement or acted upon at the 2027 Annual Meeting.

Householding Information

Unless we have received contrary instructions, we may send a single copy of the Annual Report, this Proxy Statement or Notice of Internet Availability of Proxy Materials, as applicable, to any household at which two or more stockholders reside if we believe the stockholders are members of the same family. This process, known as “householding,” reduces the volume of duplicate information received at any one household and helps to reduce our expenses. However, if stockholders prefer to receive multiple sets of our disclosure documents at the same address this year or in future years, the stockholders should follow the instructions described below. We will deliver promptly upon written or oral request of as stockholder a separate copy of the Annual Report, this Proxy Statement or Notice of Internet Availability of Proxy Materials, as applicable, to stockholder at a shared address to which a single copy of the documents was delivered. Similarly, if an address is shared with another stockholder and together both of the stockholders would like to receive only a single set of our disclosure documents, the stockholders should follow these instructions:

Electing to receive future proxy materials electronically will help us conserve natural resources and reduce the cost of delivering our proxy materials.

If you elect to receive future proxy materials electronically, you will receive an e-mail containing instructions and links to the website where our proxy materials are available and to the proxy voting website. Your election to receive proxy materials electronically by e-mail will remain in effect until you terminate it.
