This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260914015061/en/

Faruqi & Faruqi is a leading national securities law firm with offices in New York, Pennsylvania, California and Georgia. The firm has recovered hundreds of millions of dollars for investors since its founding in 1995. See www.faruqilaw.com.

As detailed below, the complaint alleges that the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose the true state of Regeneron's Phase III Fianlimab-Libtayo Study; notably, that its preliminary statistical assumptions were fundamentally flawed, that the active treatment arm was failing to achieve meaningful clinical differentiation over standard therapies, and that the trial would ultimately fail to reach statistical significance on its primary endpoint even without overperformance of the control arm.

On April 29, 2026, Defendants disclosed that the Phase III Fianlimab-Libtayo Study had been altered, expanding the number of patients in the study eligible for "analysis of progression-free survival." On this news, Regeneron's stock price fell $45.41, or approximately 6.2%, to close at $686.36 per share on April 29, 2026.

On May 15, 2026, Regeneron issued a press release announcing that the "Phase 3 Trial of Fianlimab . . . did not reach statistical significance for the primary endpoint of improvement in progression-free survival (PFS)." On this news, Regeneron's stock price fell $68.57, or approximately 9.8%, to close at $629.68 per share on May 18, 2026.

The court-appointed lead plaintiff is the investor with the largest financial interest in the relief sought by the class who is adequate and typical of class members who directs and oversees the litigation on behalf of the putative class. Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member. Your ability to share in any recovery is not affected by the decision to serve as a lead plaintiff or not.

Faruqi & Faruqi, LLP also encourages anyone with information regarding Regeneron’s conduct to contact the firm, including whistleblowers, former employees, shareholders and others.

Frequently Asked Questions (FAQ) for Investors Regarding the Regeneron Securities Class Action Lawsuit:

What is the Regeneron securities fraud lawsuit about?

Faruqi & Faruqi, LLP has filed a securities class action lawsuit against Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) on behalf of investors who purchased Regeneron securities during the Class Period. The lawsuit alleges that Regeneron and certain of its officers made materially false and misleading statements regarding the Phase III Fianlimab-Libtayo clinical study. Specifically, the complaint alleges that defendants concealed that the study's preliminary statistical assumptions were fundamentally flawed, that the active treatment arm was allegedly failing to achieve meaningful clinical differentiation over standard therapies, and that the trial would ultimately fail to reach statistical significance on its primary endpoint. The alleged fraud is said to have come to light through two disclosures: first, on April 29, 2026, when defendants announced an expansion of patients eligible for analysis of progression-free survival — causing Regeneron's stock to fall approximately 6.2% — and then on May 15, 2026, when Regeneron announced that the Phase III trial did not reach statistical significance for its primary endpoint, causing the stock to fall an additional approximately 9.8%.

Who may be eligible to participate in the lawsuit?

Investors who purchased or otherwise acquired Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) securities on the NASDAQ between August 1, 2025 and May 15, 2026, inclusive (the "Class Period"), may be eligible to participate in this lawsuit. Eligibility to participate is not limited to those who seek appointment as lead plaintiff; any investor who purchased Regeneron securities during the Class Period and suffered a loss may potentially share in any recovery obtained on behalf of the class. Investors are encouraged to review their trading records to determine whether their purchases fall within the Class Period. Participation in the litigation does not require investors to take any active litigation role beyond filing a timely claim if a recovery is ultimately achieved.

What is a lead plaintiff, and how can I seek appointment?

A lead plaintiff is a court-appointed representative who acts on behalf of all class members in directing the litigation, including working with counsel to make key strategic decisions regarding the case. Any investor who purchased Regeneron securities during the Class Period and suffered losses may move the court for appointment as lead plaintiff, but must do so no later than September 14, 2026, which is the court-established deadline for such motions. Courts generally appoint the movant with the largest financial interest in the relief sought who also satisfies the adequacy requirements of the applicable securities laws. Importantly, investors are not required to seek appointment as lead plaintiff in order to participate in or potentially share in any recovery that may result from this litigation. Those who do not seek lead plaintiff status may still submit a claim and may be eligible to receive a portion of any settlement or judgment obtained on behalf of the class.

What should investors do if they purchased Regeneron stock during the Class Period?

Investors who purchased Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) securities between August 1, 2025 and May 15, 2026 are encouraged to promptly review their brokerage and trading records to confirm the timing and size of their purchases and any resulting losses. Investors should take steps to preserve all relevant documentation, including trade confirmations, account statements, and any communications relating to their Regeneron holdings, as such records may be material to any future claim. Given that the lead plaintiff motion deadline is September 14, 2026, investors who wish to be considered for that role should act in advance of that date. Investors may wish to consult with Faruqi & Faruqi, LLP to better understand their legal rights and options before the deadline passes.

CLASS ACTION DEADLINE TONIGHT: Faruqi & Faruqi, LLP Reminds Regeneron (REGN) Investors of Securities Class Action Lawsuit Deadline on September 14, 2026

WANTAGH, N.Y. (AP) — An amateur historian has stumbled upon a provocative clue to the enduring mystery of what became of a notorious pirate who raided a royal Indian treasure ship centuries ago, implicating a co-conspirator whose name is familiar to many New Yorkers.

James Bailey, who five years ago made headlines after unearthing ancient coins believed to be linked to English pirate Capt. Henry Every, now says that colonial-era documents suggest the “King of the Pirates” and his violent crew got an assist from Thomas Jones, the namesake of Jones Beach, New York’s most visited state park after Niagara Falls.

“You have millions of visitors and generations of New Yorkers going to this beach,” Bailey said. “Nobody knew that he was actually a major player in arguably the biggest heist in the history of piracy.”

Since his big find, Bailey has pored through documents to dig even deeper into the bloody 1695 raid of the Ganj-i-Sawai on the Red Sea and the mystery of what happened to Every.

The pirate crew is said to have tortured, killed and raped those aboard the royal ship, sparking global outrage and what is considered the first worldwide manhunt. Some were caught and executed, but many others, including Every, were never heard from again and are believed to have scattered to Europe and the American colonies.

Documents, including depositions from Every’s associates, suggest Jones was recruited to serve as a “wheelman,” helping the pirates evade authorities after they made off with tens of millions of dollars' worth of gold and silver, according to Bailey.

Other documents show that New York’s governor, charged by the British crown to crack down on piracy, investigated Jones years later after he’d remade himself as the wealthy proprietor of a whaling operation on the barrier beach on Long Island that now bears his name.

Bailey’s research, which he hopes to have published, sheds light on a part of Jones’ checkered past long alluded to but never quite fleshed out in local history books, says John Hanc, author of “Jones Beach: An Illustrated History,” which includes a chapter on Jones.

Born around 1665 in the then-kingdom of Ireland, Jones was a major in the English military before moving to the American colonies. He initially settled in Rhode Island before eventually moving to New York, where he became a prominent businessman and landowner. Jones owned thousands of acres of land on early Long Island, then just a rural expanse east of the rapidly growing New York City.

But rumors of how he’d initially made his fortune persisted long after his death in 1713. Before it was demolished in the early 1800s, his crumbling mansion was said to be haunted by ghosts and strange occurrences. Jones’ grave was repeatedly desecrated by robbers searching for buried treasure before it was relocated to a family burial plot behind a nearby church.

A family history published in 1906 by one of Jones’ descendants dismissed the pirate tales as “slander” and “improbable fictions.”

“People were disposed to cast slurs upon his memory, either for mischievousness, or a spirit of malice,” Thomas Floyd-Jones wrote. “These myths were cherished for over a century after his death, which ignorance and superstition did not fail to magnify.”

Hanc and other experts say it wasn’t too far-fetched for Jones to have at least dabbled in piracy.

After serving in the British military, Jones made a career as a privateer, or a seafarer authorized by the English crown to raid the commercial ships of its rivals during wartime, said Meagan Schulman, a Fordham University doctoral candidate who specializes in 17th century piracy and wasn’t involved in Bailey’s research.

But when the conflict ended, privateers like Jones lost their special status, she said. Those that continued the high seas raids were branded pirates.

“The reality was that privateers were pirates, just sponsored by a certain government or patron,” explained Schulman, who grew up going to Jones Beach. “So maybe the short answer is, yes. Jones can be called a pirate, by some people, but he probably did not ever see himself as one.”

After helping Every and his crew evade capture, the documents cited by Bailey show Jones briefly returned to Rhode Island.

Then in 1696, Jones’ father-in-law, Thomas Townsend, a wealthy New Yorker, gifted him and his wife a significant tract of land on Long Island’s south shore, property records show.

Bailey, who recently retired from Rhode Island's corrections department, posits that allowed Jones a fresh start, as authorities continued to scour pirate-friendly New England for Every and his accomplices.

On Long Island, Bailey says Jones built a homestead and raised a family, but his pirate past was never far behind.

Three years after the Ganj-i-Sawai heist, Richard Coote, New York's colonial governor, described how one of his efforts to root out piracy had led him to Jones.

Citing witness depositions, the governor wrote in 1698 that a certain “barrel of money” traveled from the city to Long Island, where it ended up at Jones’ house. But Jones, who the governor described as “formerly a pirate,” testified that he knew nothing about the barrel.

Bailey’s findings are compelling but shouldn’t be considered conclusive, cautions Richard Blakemore, maritime history professor at the University of Reading in the United Kingdom who also wasn’t involved with Bailey’s work. After all, he said, Thomas Jones is a fairly common name.

If anything, Jones’ possible ties to Every underscore how piracy provided “foundational and multi-generational wealth” for many of the prominent families in the Northeast, says Kevin McDonald, a history professor at Loyola Marymount University in Los Angeles who wrote a book about colonial-era piracy but wasn’t involved in Bailey’s research.

“Popular images of pirates show them as outcasts, but many historians have argued the opposite, based on evidence like this,” agreed Blakemore. “It may surprise readers to find just how much early British colonies were both socially and economically connected to piracy.”
