Investors in Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) have until March 10, 2025, to join a class action lawsuit alleging securities fraud against the biotechnology giant. The lawsuit, spearheaded by the law firm Levi & Korsinsky, claims that Regeneron misled investors regarding pricing practices related to its blockbuster drug, Eylea, potentially violating federal regulations.
Allegations Against Regeneron
According to court filings, Regeneron allegedly provided credit card fee subsidies to distributors, ensuring that customers were not charged extra fees when purchasing Eylea. By doing so, the company effectively reduced the drug’s actual price while not reporting these payments as price concessions. This practice, if proven, could mean that Regeneron misrepresented the Average Sales Price (ASP) of Eylea to federal agencies, potentially violating the False Claims Act (Department of Justice).
The lawsuit covers investors who purchased Regeneron stock between November 2, 2023, and October 30, 2024. It argues that by failing to disclose these details, Regeneron may have artificially inflated its stock price, leading to financial losses for shareholders.
Potential Legal Violations
The core of the case revolves around whether Regeneron’s pricing strategy misled investors and federal regulators. The Securities and Exchange Commission (SEC) (SEC.gov) mandates that publicly traded companies provide accurate and complete financial information. If Regeneron knowingly misrepresented its ASP reporting, it could face regulatory penalties and restitution claims from investors.
Additionally, the lawsuit suggests a possible breach of the False Claims Act, which prohibits false statements made to obtain government funds. If proven, Regeneron could be held liable for damages, including penalties under federal healthcare laws (Centers for Medicare & Medicaid Services).
Impact on Investors

Shareholders who invested in Regeneron during the affected period may have suffered financial losses due to the company’s alleged misrepresentation. If the lawsuit succeeds, investors may be eligible for compensation based on stock price fluctuations linked to the alleged misinformation.
Those interested in joining the lawsuit must act before March 10, 2025. By joining as a lead plaintiff, an investor can take a more active role in directing the litigation. The lead plaintiff represents the entire class and plays a critical role in settlement negotiations and trial proceedings.

Conclusion
With the March 10, 2025 deadline approaching, Regeneron investors should carefully evaluate their legal options. This case could have significant financial implications, not only for the company but also for shareholders who may have been misled. Investors are advised to stay informed, review their investment history, and consider joining the class action if they qualify.
