EXPLANATORY NOTE — DEREGISTRATION OF SECURITIES
Effective December 31, 2022, the KLX Energy Services Holdings, Inc. Employee Stock Purchase Plan (the “Plan”) was terminated. As a result, KLX Energy Services Holdings, Inc., a Delaware corporation (the “Registrant”), is filing this Post-Effective Amendment (this “Post-Effective Amendment”) with respect to the following Form S-8 Registration Statements (collectively, the “Registration Statements”) that relate to the Plan and were previously filed by the Registrant with the Securities and Exchange Commission:
Form S-8 Registration Statement No. 333-227321 (the “First Registration Statement”), filed on September 13, 2018, that originally registered 200,000 shares of the Registrant’s common stock, par value $0.01 per share (“Registrant Common Stock”), in respect of the Plan (and also registered additional shares of Registrant Common Stock that do not relate to the Plan); and
Form S-8 Registration Statement No. 333-240198 (the “Second Registration Statement”), filed on July 30, 2020, that originally registered 300,000 shares of Registrant Common Stock in respect of the Plan.
The Registrant, by filing this Post-Effective Amendment, hereby terminates the effectiveness of the First Registration Statement with respect to the Plan and terminates the effectiveness of the Second Registration Statement entirely and removes from registration any and all shares of Registrant Common Stock that relate to the Plan that are registered but unsold or otherwise unissued under the Registration Statements as of the date hereof. This filing is made in accordance with an undertaking made by the Registrant in Part II of the Registration Statements to remove from registration by means of a post-effective amendment any securities that had been registered for issuance but remain unsold at the termination of the offering. For the avoidance of doubt, this Post-Effective Amendment does not affect the effectiveness of the First Registration Statement with respect to shares of Registrant Common Stock that are registered but do not relate to the Plan.
