KLX Energy Services Rights Offering Nearing Expiration Date

HOUSTON, TX - September 18, 2026 - KLX Energy Services Holdings, Inc. (NASDAQ: KLXE) ("KLX" or the "Company") announced today that it is nearing the previously announced expiration date for its $125 million backstopped rights offering (the "Rights Offering") of 5:00 pm, New York City time, on September 23, 2026 (the "Expiration Date"). As a reminder, each subscription right entitles the holder to purchase 3.885 shares of common stock at a subscription price of $1.49 per share. No holder (other than the Backstop Parties described in the Prospectus) is entitled to exercise subscription rights to the extent that such exercise would result in such holder, together with its affiliates and any persons acting in concert with such holder, beneficially owning more than 9.995% of the Company's outstanding common stock on a pro forma basis after giving effect to such exercise. The subscription rights will continue to trade on The Nasdaq Stock Market LLC under the symbol "KLXER" until the close of trading on the Expiration Date.

Importantly, for holders whose shares of our common stock are held in a brokerage account or are otherwise not registered directly with the Company, the deadline to exercise their subscription rights with their respective brokerage firms may be earlier. Information regarding specific broker-related deadlines should be obtained directly from the broker. The subscription rights will expire and have no value if they are not exercised prior to the Expiration Date.

The Rights Offering was made pursuant to the Company's existing effective shelf registration statement on Form S-3 (Reg. No. 333-295905) on file with the Securities and Exchange Commission (the "SEC") and the prospectus supplement (and the accompanying base prospectus) filed with the SEC on August 24, 2026 (collectively, the "Prospectus"). The Company reserves the right to extend, amend or terminate the Rights Offering, subject to certain conditions, at any time. Additional information regarding the Rights Offering is set forth in the Prospectus.

Copies of the Prospectus, the subscription rights certificates and other related documents were mailed to all holders on or about August 24, 2026 and can also be accessed through the SEC's website at www.sec.gov. Holders of shares of common stock in "street name" through a brokerage account, bank or other nominee must instruct their broker, bank or nominee whether to exercise subscription rights on their behalf.
