Karth v. Keryx Biopharmaceuticals, Inc., No. 19-1964 (1st Cir. 2021)Annotate this Case
The First Circuit affirmed the judgment of the district court in favor of Defendants, denying Plaintiff's motion for class certification, and denying Plaintiff's motion to file a third amended complaint, holding that Defendant sufficiently warned investors about the vulnerability of its manufacturing infrastructure so that Plaintiff knew of the investment risks when he purchased his shares.
Plaintiff was an investor who lost money when he bought stock in Keryx Biopharmaceuticals, Inc. and watched the value plummet soon after that purchase. Plaintiff sued Keryx and its executives, alleging that Keryx's inadequate disclosures about its manufacturing defects amounted to securities fraud. The district court allowed Defendants' motion for judgment on the pleadings. The First Circuit affirmed, holding that Plaintiff failed to state a claim under section 10(b) of the Securities Exchange Act.
