IBRX Investor Alert: ImmunityBio Securities Fraud Lawsuit - Investors With Losses May Seek to Lead the Class Action After FDA Allegedly Exposed Misleading Claims: Levi & Korsinsky

Critical Information: $1.98 Per Share Loss Quantifies Alleged Investor Damages After FDA Warning Letter

NEW YORK, April 22, 2026 /PRNewswire/ -- Levi & Korsinsky, LLP reminds purchasers of ImmunityBio, Inc. (NASDAQ: IBRX) securities of a pending securities class action.

THE CASE: A class action seeks to recover damages for investors who purchased IBRX securities between January 19, 2026 and March 24, 2026.

YOUR OPTIONS: You may be entitled to compensation without payment of any out-of-pocket fees. See if you can recover losses from your IBRX investment or contact Joseph E. Levi, Esq. at [email protected] or (212) 363-7500.

On March 24, 2026, ImmunityBio shares lost $1.98 per share, falling 21% to close at $7.42. The day prior, shares had traded as high as $9.40. The collapse followed the publicization of an FDA Warning Letter that determined ImmunityBio's promotional communications about its bladder cancer drug ANKTIVA were false or misleading and misbranded the product in violation of federal law.

The March 24 Market Repricing

The market removed artificial inflation from IBRX shares after the FDA Warning Letter revealed that the Company's Executive Chairman had made claims about ANKTIVA that the agency found to be unsupported by clinical data. The FDA determined that a TV advertisement and a January 19, 2026 podcast appearance created "a misleading impression that Anktiva, a treatment for a certain type of bladder cancer, can cure and even prevent all cancer." The filing states that the FDA called these violations "concerning from a public health perspective" because they "grossly misrepresent the benefits of Anktiva."

How the Market Absorbed the Corrective Disclosure

• IBRX shares traded at $9.40 on March 23, 2026, the last trading day before the FDA Warning Letter became public
• Shares opened sharply lower on March 24 and closed at $7.42, a single-day loss of $1.98 per share
• The 21% decline reflected the market's rapid reassessment of the Company's promotional claims about ANKTIVA
• Bloomberg published an article titled "ImmunityBio Plunges After Getting FDA Warning on Cancer Drug," amplifying the corrective information across financial media
• The FDA letter was dated March 13, 2026, meaning the agency had already concluded its review before the market learned of the findings

What the Decline Measured

The lawsuit contends that the stock price decline on March 24, 2026 represented the removal of artificial inflation that had entered IBRX shares beginning January 19, 2026 when the Executive Chairman appeared on a nationally broadcast podcast and made sweeping claims about ANKTIVA's capabilities. According to the action, shareholders who purchased IBRX stock at prices inflated by these allegedly false statements suffered direct, quantifiable financial harm when the FDA's findings corrected the market's understanding of the drug's actual approved use and clinical evidence.

"When companies fail to disclose material information, shareholders may suffer significant losses. The sharp repricing of IBRX shares after the FDA Warning Letter suggests the market had been relying on promotional claims that the agency determined were false or misleading." -- Joseph E. Levi, Esq.
