EXPLANATORY NOTE

DEREGISTRATION OF UNSOLD SECURITIES

Expro Ltd, an exempted company incorporated under the laws of the Cayman Islands (“Expro Ltd”), as successor by merger to Expro Group Holdings N.V., a public limited liability company previously organized under the laws of the Netherlands (“Expro N.V.”), is filing this Post-Effective Amendment No. 1 (this “Amendment”) to the Registration Statement on Form S-3 (Registration Statement No. 333-214509) (the “Registration Statement”), which was initially filed with the Securities and Exchange Commission on November 8, 2016 to register the offer and sale of 12,804,233 shares of common stock of Frank’s International N.V., the predecessor to Expro N.V., by certain selling shareholders named therein.

On July 13, 2026, Expro N.V. completed its previously announced redomiciliation transaction (the “Redomiciliation”) pursuant to which (a) Expro N.V. merged with and into Expro Luxembourg S.A., a public limited liability company incorporated under the laws of Luxembourg (“Expro Luxembourg”), with Expro Luxembourg surviving (the “Luxembourg Merger”), and (b) following completion of the Luxembourg Merger, Expro Luxembourg merged with and into Expro Ltd, with Expro Ltd continuing as the surviving company (together with the Luxembourg Merger, the “Mergers”). In the Mergers, each share of common stock, nominal value €0.06 per share, of Expro N.V. (“Expro N.V. Common Shares”) issued and outstanding immediately prior to the Mergers was automatically canceled and ultimately exchanged for one ordinary share, par value $0.0001 per share, of Expro Ltd (“Expro Ltd Ordinary Shares”), and, as a result, the former shareholders of Expro N.V. automatically became shareholders of Expro Ltd, holding the same number and percentage of Expro Ltd Ordinary Shares as they held of Expro N.V. Common Shares immediately prior to the Mergers. Expro Ltd replaced Expro N.V. as the publicly held company traded on the New York Stock Exchange.

As a result of the completion of the Redomiciliation, this Amendment is being filed by Expro Ltd, as successor by merger to Expro N.V., to withdraw and remove from registration all of the securities that remain unsold under the Registration Statement. In accordance with an undertaking made by Expro N.V. in the Registration Statement to remove from registration, by means of a post-effective amendment, any of the securities registered under the Registration Statement that remain unsold at the termination of the offering, Expro Ltd, as successor by merger to Expro N.V., hereby removes from registration any and all of the securities registered but unsold under the Registration Statement as of the date hereof. The Registration Statement is hereby amended, as appropriate, to reflect the deregistration of such securities.

SIGNATURE

Pursuant to the requirements of the Securities Act of 1933, Expro Ltd, as successor by merger to Expro Group Holdings N.V., certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Amendment to the Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Houston, State of Texas, on July 23, 2026.

No other person is required to sign this Amendment in reliance upon Rule 478 under the Securities Act of 1933, as amended.
