A securities class action against ChampionX Corporation (CHX) puts the company's stock buyback program under a spotlight. The lawsuit, filed by Robbins LLP, alleges ChampionX repurchased 216,000 shares from investors between February 29 and April 1, 2024, while withholding material nonpublic information. That information was Schlumberger Limited's (SLB) offers to buy ChampionX at a premium above where the stock traded at the time.
The timing matters. ChampionX was buying its own shares from the open market. At the same time, according to the complaint, the board and executives knew SLB was interested in acquiring the whole company at a price significantly higher than the buyback price. If that information had been disclosed, any reasonable investor would have understood the stock was worth more than what ChampionX was paying to retire those shares.
The market found out about SLB's interest later. When it did, CHX stock jumped sharply. That move punished the sellers who had already exited during the buyback window. They sold at a discount to what the shares were likely worth, the lawsuit argues.
ChampionX is an oilfield services company. It sells chemistry solutions, artificial lift systems, and equipment for drilling and production. SLB, the would-be acquirer, trades under the ticker SLB and holds an Alpha Score of 51 out of 100, a mixed rating in AlphaScala's model. The overlap between the two companies is direct: both serve the energy sector's upstream operations.
For shareholders who sold CHX during the class period, the path to recovery is procedural. Anyone who sold between February 29 and April 1, 2024 can potentially participate in the class action. To serve as lead plaintiff – the representative party who directs the litigation – they must file papers with the court by July 14, 2026. Shareholders who do nothing remain absent class members and can still share in any settlement or judgment.
The case is at its earliest stage. No court has ruled on the merits. Robbins LLP takes the case on contingency, meaning shareholders pay no upfront fees.
The deadline is eight weeks from the date of the filing. For traders who held CHX through that February-to-April window in 2024, the clock is ticking.
