Investors Urged to Join Class Action Against Ultragenyx Pharmaceutical Over Securities Fraud Allegations

Investors Target Ultragenyx Pharmaceutical in New Securities Fraud Lawsuit

In a significant development for stakeholders, The Schall Law Firm has announced the initiation of a class action lawsuit against Ultragenyx Pharmaceutical Inc. (NASDAQ: RARE). This lawsuit targets the company due to alleged violations of the Securities Exchange Act of 1934 that have raised serious concerns among investors.

Background of the Lawsuit

The notice issued by The Schall Law Firm advises investors who purchased Ultragenyx securities between August 3, 2023, and December 26, 2025, to reach out before the deadline on April 6, 2026. The lawsuit hinges on claims that Ultragenyx provided investors with false and misleading information regarding its understanding of drug effects on patients suffering from Osteogenesis Imperfecta (OI). Such misinformation has reportedly resulted in substantial investor losses.

Allegations of Misleading Statements

According to the complaint, Ultragenyx's statements to the market were overly optimistic, creating a false impression of the efficacy of one of its drug candidates. Specifically, this glaring optimism came to light following the results of the Phase III ORBIT study that failed to demonstrate a statistically significant reduction in annualized fracture rate (AFR) among participants. Such disclosure revealed the misleading nature of the company’s public statements, potentially putting investors at a significant disadvantage.

By doing so, they may have an opportunity to recover their financial losses incurred during the specified Class Period.
