The DJS Law Group has filed a class action lawsuit against Immutep Limited, the NASDAQ-listed company trading under the ticker IMMP, alleging violations of federal securities law. The complaint invokes Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as well as Rule 10b-5 promulgated under that statute. The Los Angeles-based law firm announced the action on June 29, 2026, and is calling on investors to contact the firm to discuss their rights.
The Legal Claims at Issue
The lawsuit rests on two of the most heavily litigated provisions in federal securities law. Section 10(b) and Rule 10b-5 form the backbone of securities fraud liability, broadly prohibiting material misstatements or omissions made in connection with the purchase or sale of a security. Section 20(a) reaches further, extending liability to individuals who exercise control over a primary violator — a provision plaintiffs typically deploy to sweep in senior executives alongside the corporate entity itself.
The DJS Law Group's announcement does not identify which specific disclosures or statements are alleged to be false or misleading, nor does it specify a proposed class period or the identity of any individual defendants beyond Immutep as an entity.
Implications for IMMP Shareholders
Securities class actions brought under these provisions represent a material legal and reputational overhang for any public company. The DJS Law Group is actively soliciting IMMP investors who believe they suffered losses, a standard step in the process of assembling a prospective plaintiff class ahead of any lead plaintiff appointment.
Because the source announcement provides only the filing's statutory framework and the law firm's contact information, the precise factual theory underlying the allegations — what Immutep is accused of saying, when it said it, and what the firm allegedly knew — remains undisclosed at this stage. That detail will become public once the full complaint is on the docket.
Investors holding or having held positions in Immutep shares who believe they may have been affected should review any forthcoming complaint independently and consult qualified legal counsel regarding their options.
