II Weatherford International plc — 2026 Shareholder Meetings

A Message From Our Board of Directors

Dear Fellow Weatherford Shareholder,

Introduction

After careful review by our Board of Directors (the “Board”) and management team, we have decided to simplify and streamline the organizational, statutory and regulatory structure of Weatherford and its subsidiaries by restructuring the company to redomesticate to the United States and establish our ultimate parent company in Texas. Weatherford has long called Texas “home,” with our corporate headquarters in Houston, Texas, and operations throughout the state. In fact, our roots go back to the Weatherford Spring Company in Weatherford, Texas more than 80 years ago. We have been considering a redomestication or similar transaction for several years now, and we believe the time is right to make the move. We are pleased to invite you to participate in two meetings of the shareholders of Weatherford International plc (“Weatherford-Ireland”) to be held on June 11, 2026 at 2000 Saint James Place, Marcellus Room, Houston, Texas 77056, United States of America. The first, a special court-ordered shareholder meeting, is to be held at 8:00 a.m. (Central Time) / 2:00 p.m. (Irish Time), and the second, the annual general meeting of shareholders of Weatherford-Ireland is to be held at 8:10 a.m. (Central Time) / 2:10 p.m. (Irish Time), or if the special court-ordered shareholder meeting has not concluded by such time, as soon as possible after the conclusion of such meeting.

We are making the accompanying Proxy Statement available in connection with the solicitation by our Board of proxies to be voted at these two meetings of our shareholders as described in the accompanying Proxy Statement. At these two meetings, you will be asked to vote on a number of proposals, including proposals for a “scheme of arrangement” under Irish law that, if approved, will change the place of incorporation of our ultimate parent company from Ireland to Texas. You will also be asked to vote on our typical proposals relating to the ordinary business of our annual general meeting, which proposals will be familiar to you.

Completion of the proposed scheme of arrangement will result in the cancellation of your Weatherford-Ireland ordinary shares and the replacement of those shares with an equal number of shares of common stock issued by Weatherford International Corp, a Texas corporation(“Weatherford-US”). Weatherford-US is a newly-formed, indirect, wholly-owned subsidiary of Weatherford-Ireland, formed by Weatherford for purposes of effecting the scheme of arrangement and redomestication. As a result of the scheme of arrangement, Weatherford-US will become the new ultimate parent company of the Weatherford group of companies, and you will become a Weatherford-US stockholder. Your rights as a stockholder of Weatherford-US will be governed by Texas law, the Texas Charter and the Bylaws. It is important to note that there are differences between Texas and Irish law and certain of the rights that you currently enjoy as a shareholder of Weatherford-Ireland will change, including in relation to the issuance of shares, regulation of business combinations (such as takeovers, acquisitions, and mergers) and appraisal and dissenter rights. You should therefore carefully consider the section entitled “Comparison of Rights of Shareholders and Powers of the Board of Directors” in the accompanying Proxy Statement. Our listing on the Nasdaq is expected to continue under the same ticker symbol, “WFRD.”

While we believe that our multi-national business structure under an Irish parent company has served us and our shareholders well for many years, the time is right to move forward with a Texas parent for the Weatherford group of companies. After considering various factors, the Board unanimously determined that this proposed redomestication will, among other benefits, simplify Weatherford’s organizational, statutory and regulatory framework and allow us to gain efficiencies in our corporate treasury, cash management, risk management and tax functions. The Board believes that the proposed scheme of arrangement, other related proposals and resulting redomestication will achieve a more appropriate structure for Weatherford going forward. The reasons for the proposed scheme of arrangement and other related proposals are discussed in further detail in the accompanying Proxy Statement. On behalf of our Board, thank you for your continued support.

Recommendation: The Board unanimously recommends that you vote FOR each of the proposals described in the accompanying Proxy Statement.

Your vote is very important regardless of the number of Weatherford-Ireland ordinary shares that you own. Please read the accompanying Proxy Statement for more information on how to vote your shares. If you require assistance with voting, please contact our proxy solicitor, Okapi Partners. Banks and brokerage firms and all non-U.S. callers, please call: +1 (212) 297-0720. Shareholders and all others, please call toll-free: +1 (855) 208-8902, or e-mail info@okapipartners.com.

Sincerely,

Weatherford International plc — 2026 Shareholder Meetings III
