Dear Shareholder,

On behalf of the Board of Directors (the “Board”) of National Energy Services Reunited Corp. (the “Company,” “NESR,” “our” or “we”), it is my pleasure to extend to you an invitation to attend the Company’s 2026 annual general meeting of shareholders (the “Annual General Meeting”). The Annual General Meeting will be held at:

For your convenience, you may attend the Annual General Meeting in person or through a webcast. You may attend the webcast of the meeting via the Internet atwww.virtualshareholdermeeting.com/NESR2026 when you enter your 16-digit control number included with the proxy card. Instructions on how to attend and participate in the Annual General Meeting via the webcast are posted atwww.virtualshareholdermeeting.com/NESR2026. You will be able to vote your shares while attending the Annual General Meeting by following the instructions on the website.

The Notice of 2026 Annual General Meeting and Proxy Statement describes the business to be transacted at the Annual General Meeting and provides other information concerning the Company. The principal business to be transacted at the Annual General Meeting will be (1) the re-election of five of our current directors to the Board (collectively, the “director nominees,” “nominated directors” or “nominees to the Board”), each for a term of one year, (2) to approve an advisory resolution on executive compensation (3) to approve an advisory resolution on the frequency of future advisory resolutions on executive compensation, and (4) to ratify the appointment of Grant Thornton Audit and Accounting Limited (Dubai Branch) (“GT”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026. The Board unanimously recommends that shareholders vote “FOR” the election to the Board of each of the nominated directors, “FOR” the advisory, non-binding resolution to approve the compensation provided to our named executive officers for 2025, “ONE YEAR” for the advisory, non-binding resolution on the frequency of future advisory resolutions on executive compensation and “FOR” the ratification of the appointment of GT as our independent registered public accounting firm for the fiscal year ending December 31, 2026.

For NESR, 2025 represented the third consecutive year of sector-leading growth, operational advancement, and key capital markets achievements. Despite prevailing market volatility, the outlook remains bright, with the Company entering its next phase of expansion from its strongest operational position ever.

We know that many of our shareholders will be unable to attend the Annual General Meeting. Proxies are solicited so that each shareholder has an opportunity to vote on all matters that are scheduled to come before the Annual General Meeting. Whether or not you plan to attend the Annual General Meeting in person or via webcast, we hope that you will have your shares represented by voting online, by telephone, or by completing and returning a proxy card or voting instruction card as soon as possible. You may, of course, attend the Annual General Meeting and vote in person or online even if you have previously voted.

Sincerely,

NOTICE OF 2026 ANNUAL GENERAL MEETING AND PROXY STATEMENT
