RPC INC

We are furnishing the proxy materials to stockholders on or about March 14, 2024. The Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Stockholders to be held on April 23, 2024. Proxy Statement and the Annual Report on Form 10-K are available athttps://www.viewproxy.com/RPC/2024.

The following information concerning the proxy and the matters to be acted upon at the Annual Meeting of Stockholders to be held on April 23, 2024 is submitted by the Company to the stockholders in connection with the solicitation of proxies on behalf of the Company’s Board of Directors.

SOLICITATION OF AND POWER TO REVOKE PROXY

A form of proxy is enclosed. Each proxy submitted will be voted as directed, but if not otherwise specified, proxies solicited by the Board of Directors of the Company will be voted in favor of the candidates for election to the Board of Directors, in favor of ratification of the appointment of Grant Thornton LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024, and in favor of the proposed 2024 Stock Incentive Plan.

A stockholder executing and delivering a proxy has power to revoke the same and the authority thereby given at any time prior to the exercise of such authority, if they so elect, by contacting either proxy holder, by timely submitting a later dated proxy changing their vote, or by attending the meeting and voting in person. However, a beneficial stockholder who holds his shares in street name must secure a proxy from his broker before he can attend the meeting and vote. All costs of solicitation have been, and will be, borne by the Company.

HOUSEHOLDING AND DELIVERY OF NOTICE OR PROXY MATERIALS

The Company has adopted the process called “householding” for any notice or proxy materials in order to reduce printing costs and postage fees. Householding means that stockholders who share the same last name and address will receive only one copy of the notice or proxy materials, unless we receive contrary instructions from any stockholder at that address.

If you prefer to receive multiple copies of the proxy materials at the same address, additional copies will be provided to you promptly upon written or oral request. If you are a stockholder of record, you may contact us by writing to the Company at 2801 Buford Highway NE, Suite 300, Atlanta, GA 30329 or by calling 404-321-2140. Eligible stockholders of record receiving multiple copies of the proxy materials can request householding by contacting the Company in the same manner.
