A Complaint has filed on behalf of investors who sold ChampionX common stock during the Class Period, alleging that the defendants failed to disclose material information, which artificially deflated the price of ChampionX common stock.
Per the allegations of the Complaint, on February 29, 2024, ChampionX received an unsolicited non-public offer from Schlumberger Limited to purchase all the outstanding shares of ChampionX for $36.70 per share. On March 7, 2024, Schlumberger raised its offer to $37.80 per share. The ChampionX class action lawsuit alleges that while these offers were on the table and unknown to the investing public, ChampionX was repurchasing its common stock at market prices significantly below the prices offered by Schlumberger. ChampionX had an obligation to disclose that it had received a formal acquisition offer from Schlumberger or abstain from purchasing ChampionX stock from unsuspecting investors.
During the Class Period, ChampionX's average stock price was $33.32 per share. On Tuesday, April 2, 2024, during pre-market hours, ChampionX disclosed the merger with Schlumberger. The merger eventually closed on July 16, 2025, with Schlumberger acquiring ChampionX for $40.58 per share.

WHY ROSEN LAW: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience, resources, or any meaningful peer recognition. Many of these firms do not actually handle securities class actions, but are merely middlemen that refer clients or partner with law firms that actually litigate the cases. Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm has achieved the largest ever securities class action settlement against a Chinese Company. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered billions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs’ Bar. Many of the firm’s attorneys have been recognized by Lawdragon and Super Lawyers.
DETAILS OF THE CASE: According to the lawsuit, defendants throughout the Class Period failed to disclose material information, which artificially deflated the price of ChampionX common stock. On February 29, 2024, ChampionX received an unsolicited non-public offer from Schlumberger Limited to purchase all the outstanding shares of ChampionX for $36.70 per share. On March 7, 2024, Schlumberger raised its offer to $37.80 per share. The lawsuit alleges that while these offers were on the table and unknown to the investing public, ChampionX was repurchasing its common stock at market prices significantly below the prices offered by Schlumberger.

Philadelphia, Pennsylvania--(Newsfile Corp. - July 10, 2026) - National plaintiffs' law firm Berger Montague PC announces a class action lawsuit against ChampionX Corporation (NASDAQ: CHX) ("ChampionX" or the "Company") on behalf of investors who sold ChampionX common stock during the period from February 29, 2024 through April 1, 2024 (the "Class Period").
Investor Deadline: Investors who sold ChampionX common stock during the Class Period may, no later than July 14, 2026, seek to be appointed as a lead plaintiff representative of the class. To learn your rights, CLICK HERE.
Prior to its July 2025 acquisition by SLB, ChampionX was a global leader in chemistry solutions and engineered equipment for the oil and gas industry.
The lawsuit alleges that while ChampionX and its senior executives were in possession of material, non-public information — specifically, unsolicited acquisition offers from SLB — the Company repurchased a significant amount of its own shares at market prices artificially deflated by the concealment of that information.
Specifically, on February 29, 2024, ChampionX received an unsolicited, non-public offer from SLB to acquire all outstanding shares of ChampionX for $36.70 per share. On March 7, 2024, SLB raised its offer to $37.80 per share. Throughout the Class Period, ChampionX's average stock price was $33.32 per share — materially below the undisclosed offer prices. Despite having an obligation to either disclose the acquisition offers or abstain from purchasing ChampionX stock, the Company continued to repurchase shares at those depressed prices and benefitted significantly from keeping this information from investors.
On April 2, 2024, during pre-market hours, ChampionX disclosed that it had reached an agreement to be acquired by SLB. The merger eventually closed on July 16, 2025, with SLB acquiring ChampionX for $40.58 per share.

The lawsuit alleges that defendants repurchased millions of dollars’ worth of ChampionX shares without disclosing material nonpublic information about Schlumberger Limited’s offers to purchase ChampionX at a premium to then-current prices, which, if disclosed as required, would have indicated to investors that ChampionX’s stock was worth significantly more.

New York, New York--(Newsfile Corp. - July 8, 2026) - WHY: Rosen Law Firm, a global investor rights law firm, reminds sellers of common stock of ChampionX Corporation (NASDAQ: CHX) between February 29, 2024 and April 1, 2024, inclusive (the "Class Period"), of the important July 14, 2026 lead plaintiff deadline.

A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than July 14, 2026. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.
WHY ROSEN LAW: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience, resources, or any meaningful peer recognition. Many of these firms do not actually handle securities class actions, but are merely middlemen that refer clients or partner with law firms that actually litigate the cases. Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm has achieved the largest ever securities class action settlement against a Chinese Company. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered billions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs' Bar. Many of the firm's attorneys have been recognized by Lawdragon and Super Lawyers.
DETAILS OF THE CASE: According to the lawsuit, defendants throughout the Class Period failed to disclose material information, which artificially deflated the price of ChampionX common stock. On February 29, 2024, ChampionX received an unsolicited non-public offer from Schlumberger Limited to purchase all the outstanding shares of ChampionX for $36.70 per share. On March 7, 2024, Schlumberger raised its offer to $37.80 per share. The lawsuit alleges that while these offers were on the table and unknown to the investing public, ChampionX was repurchasing its common stock at market prices significantly below the prices offered by Schlumberger. ChampionX had an obligation to disclose that it had received a formal acquisition offer from Schlumberger or abstain from purchasing ChampionX stock from unsuspecting investors. During the Class Period, ChampionX's average stock price was $33.32 per share. On Tuesday, April 2, 2024, during pre-market hours, ChampionX disclosed the merger with Schlumberger. The merger eventually closed on July 16, 2025, with Schlumberger acquiring ChampionX for $40.58 per share.
To join the ChampionX class action, go to https://rosenlegal.com/cases/championx-corporation/join or call Phillip Kim, Esq. toll-free at 866-767-3653 or email [email protected] for information on the class action.
No Class Has Been Certified. Until a class is certified, you are not represented by counsel unless you retain one. You may select counsel of your choice. You may also remain an absent class member and do nothing at this point. An investor's ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.

What are the allegations?
Shareholders allege that ChampionX Corporation repurchased shares of its stock in violation of securities laws. According to the complaint, during the class period, defendants repurchased 216,000 shares of ChampionX stock – worth millions of dollars – from unsuspecting investors without disclosing material nonpublic information about Schlumberger Limited’s (SLB) offers to purchase ChampionX at a premium to then-current prices. If this information had been disclosed as required, it would have indicated to investors that ChampionX’s stock was worth significantly more than its trading price.
Plaintiff alleges that when investors learned the truth that SLB was willing to buy all the Company's outstanding stock for a significant premium above the trading price, ChampionX's stock price climbed sharply, harming investors who sold during the class period.
What can shareholders do now? You may be eligible to participate in the class action against ChampionX Corporation. Shareholders who wish to serve as lead plaintiff for the class must submit their papers with the court by July 14, 2026.

PHILADELPHIA, July 07, 2026 (GLOBE NEWSWIRE) -- National plaintiffs’ law firm Berger Montague PC announces a class action lawsuit against ChampionX Corporation (NASDAQ: CHX) (“ChampionX” or the “Company”) on behalf of investors who sold ChampionX common stock during the period from February 29, 2024 through April 1, 2024 (the “Class Period”).
Investor Deadline: Investors who sold ChampionX common stock during the Class Period may, no later than July 14, 2026, seek to be appointed as a lead plaintiff representative of the class. To learn your rights, CLICK HERE.
Prior to its acquisition by SLB in July 2025, ChampionX, headquartered in The Woodlands, TX, was a provider of chemistry solutions and technologies serving the global oil and gas sector.
The Complaint alleges that throughout the Class Period, ChampionX purchased Company shares at artificially depressed prices due to material non-public information. Specifically, defendants allegedly failed to disclose that: (i) ChampionX had received an unsolicited, non-public acquisition offer from SLB; (ii) ChampionX had an obligation to either disclose the offer or abstain from repurchasing its shares; and (iii) while those offers were on the table and unknown to the investing public, ChampionX was repurchasing its common stock at market prices significantly below the prices offered by SLB.
On February 29, 2024, ChampionX received an unsolicited, non-public offer from SLB to acquire all outstanding shares at $36.70 per share. On March 7, 2024, SLB raised its offer to $37.80 per share. During the Class Period, ChampionX’s average stock price was $33.32 per share — significantly below the undisclosed offer prices.
On April 2, 2024, during pre-market hours, ChampionX disclosed the merger with SLB. The merger eventually closed on July 16, 2025, with SLB acquiring ChampionX for $40.58 per share.

Why: Rosen Law Firm, a global investor rights law firm, reminds sellers of common stock of ChampionX Corporation (NASDAQ: CHX) between February 29, 2024 and April 1, 2024 (the "Class Period"), of the important July 14, 2026 lead plaintiff deadline.
So what: If you sold ChampionX common stock during the Class Period you may be entitled to compensation without payment of any out of pocket fees or costs through a contingency fee arrangement.
What to do next: To join the ChampionX class action, go to https://rosenlegal.com/cases/championx-corporation/join or call Phillip Kim, Esq. toll-free at 866-767-3653 or email [email protected] for information on the class action. A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than July 14, 2026. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.
Why Rosen Law: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience, resources, or any meaningful peer recognition. Many of these firms do not actually handle securities class actions, but are merely middlemen that refer clients or partner with law firms that actually litigate the cases. Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm has achieved the largest ever securities class action settlement against a Chinese Company. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered billions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs' Bar. Many of the firm's attorneys have been recognized by Lawdragon and Super Lawyers.
Details of the case: According to the lawsuit, defendants throughout the Class Period failed to disclose material information, which artificially deflated the price of ChampionX common stock. On February 29, 2024, ChampionX received an unsolicited non-public offer from Schlumberger Limited to purchase all the outstanding shares of ChampionX for $36.70 per share.

WHY ROSEN LAW: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience, resources, or any meaningful peer recognition. Many of these firms do not actually handle securities class actions, but are merely middlemen that refer clients or partner with law firms that actually litigate the cases. Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm has achieved the largest ever securities class action settlement against a Chinese Company. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered billions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs' Bar. Many of the firm's attorneys have been recognized by Lawdragon and Super Lawyers.
DETAILS OF THE CASE: According to the lawsuit, defendants throughout the Class Period failed to disclose material information, which artificially deflated the price of ChampionX common stock. On February 29, 2024, ChampionX received an unsolicited non-public offer from Schlumberger Limited to purchase all the outstanding shares of ChampionX for $36.70 per share. On March 7, 2024, Schlumberger raised its offer to $37.80 per share. The lawsuit alleges that while these offers were on the table and unknown to the investing public, ChampionX was repurchasing its common stock at market prices significantly below the prices offered by Schlumberger. ChampionX had an obligation to disclose that it had received a formal acquisition offer from Schlumberger or abstain from purchasing ChampionX stock from unsuspecting investors. During the Class Period, ChampionX's average stock price was $33.32 per share. On Tuesday, April 2, 2024, during pre-market hours, ChampionX disclosed the merger with Schlumberger. The merger eventually closed on July 16, 2025, with Schlumberger acquiring ChampionX for $40.58 per share.

Philadelphia, Pennsylvania--(Newsfile Corp. - July 2, 2026) - National plaintiffs' law firm Berger Montague PC announces a class action lawsuit against ChampionX Corporation (NASDAQ: CHX) ("ChampionX" or the "Company") on behalf of investors who sold ChampionX common stock during the period from February 29, 2024 through April 1, 2024 (the "Class Period").
Investor Deadline: Investors who sold ChampionX common stock during the Class Period may, no later than July 14, 2026, seek to be appointed as a lead plaintiff representative of the class. To learn your rights, CLICK HERE.
Prior to its July 2025 acquisition by SLB, ChampionX was a global leader in chemistry solutions and engineered equipment for the oil and gas industry.
The lawsuit alleges that while ChampionX and its senior executives were in possession of material, non-public information - specifically, unsolicited acquisition offers from SLB - the Company repurchased a significant amount of its own shares at market prices artificially deflated by the concealment of that information.
Specifically, on February 29, 2024, ChampionX received an unsolicited, non-public offer from SLB to acquire all outstanding shares of ChampionX for $36.70 per share. On March 7, 2024, SLB raised its offer to $37.80 per share. Throughout the Class Period, ChampionX's average stock price was $33.32 per share - materially below the undisclosed offer prices. Despite having an obligation to either disclose the acquisition offers or abstain from purchasing ChampionX stock, the Company continued to repurchase shares at those depressed prices and benefitted significantly from keeping this information from investors.
On April 2, 2024, during pre-market hours, ChampionX disclosed that it had reached an agreement to be acquired by SLB. The merger eventually closed on July 16, 2025, with SLB acquiring ChampionX for $40.58 per share.
If you are a ChampionX investor and would like to learn more about this action, CLICK HERE or please contact Berger Montague: Andrew Abramowitz at [email protected] or (215) 875-3015, or Caitlin Adorni at [email protected] or (267) 764-4865.

Per the allegations of the Complaint, on February 29, 2024, ChampionX received an unsolicited non-public offer from Schlumberger Limited to purchase all the outstanding shares of ChampionX for $36.70 per share. On March 7, 2024, Schlumberger raised its offer to $37.80 per share. The ChampionX class action lawsuit alleges that while these offers were on the table and unknown to the investing public, ChampionX was repurchasing its common stock at market prices significantly below the prices offered by Schlumberger. ChampionX had an obligation to disclose that it had received a formal acquisition offer from Schlumberger or abstain from purchasing ChampionX stock from unsuspecting investors.
During the Class Period, ChampionX’s average stock price was $33.32 per share. On Tuesday, April 2, 2024, during pre-market hours, ChampionX disclosed the merger with Schlumberger. The merger eventually closed on July 16, 2025, with Schlumberger acquiring ChampionX for $40.58 per share.

What are the allegations? Robbins LLP is Investigating Allegations that ChampionX Corporation (CHX) Repurchased Shares of its Stock in Violation of Securities Laws
According to the complaint, during the class period, defendants repurchased 216,000 shares of ChampionX stock - worth millions of dollars - from unsuspecting investors without disclosing material nonpublic information about Schlumberger Limited's (SLB) offers to purchase ChampionX at a premium to then-current prices. If this information had been disclosed as required, it would have indicated to investors that ChampionX's stock was worth significantly more than its trading price.
Plaintiff alleges that when investors learned the truth that SLB was willing to buy all the Company's outstanding stock for a significant premium above the trading price, ChampionX's stock price climbed sharply, harming investors who sold during the class period.

WHY ROSEN LAW: We encourage investors to select qualified counsel with a track record of success in leadership roles.

Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm has achieved the largest ever securities class action settlement against a Chinese Company. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered billions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs' Bar. Many of the firm's attorneys have been recognized by Lawdragon and Super Lawyers.
DETAILS OF THE CASE: According to the lawsuit, defendants throughout the Class Period failed to disclose material information, which artificially deflated the price of ChampionX common stock. On February 29, 2024, ChampionX received an unsolicited non-public offer from Schlumberger Limited to purchase all the outstanding shares of ChampionX for $36.70 per share.

New York, New York--(Newsfile Corp. - June 26, 2026) - Bronstein, Gewirtz & Grossman, LLC, a nationally recognized investor-rights law firm, announces that a class action lawsuit has been filed against ChampionX Corporation (NASDAQ: CHX) and certain of its officers.
This lawsuit seeks to recover damages against Defendants for alleged violations of the federal securities laws on behalf of all persons and entities that purchased or otherwise acquired ChampionX securities between February 29, 2024 and April 1, 2024, both dates inclusive (the "Class Period"). Such investors are encouraged to join this case by visiting the firm's site: bgandg.com/CHX.
ChampionX Case Details
The Complaint alleges that, throughout the Class Period, Defendants made materially false and misleading statements and/or failed to disclose that:
while repurchasing millions of dollars' worth of ChampionX Corporation ("ChampionX" or the "Company") common stock, Defendants were in possession of material nonpublic information regarding offers made by Schlumberger Limited ("SLB") to acquire ChampionX at a premium to prevailing market prices; Defendants failed to either abstain from trading or disclose SLB's offer(s), which, if disclosed, would have signaled to investors that ChampionX's stock was worth significantly more than its trading price; Defendants further failed to disclose subsequent offers and negotiations involving ChampionX and SLB; and as a result, Defendants' statements about the Company's business, operations, and prospects were materially false and misleading at all relevant times.What's Next for ChampionX Investors?
