Notice to Pension Funds, Asset Managers, and Fiduciaries Holding IMMP: An 83% Single-Day Loss in Immutep ADRs Raises Urgent Questions About Portfolio Exposure and Fiduciary Recovery Obligations
NEW YORK, May 28, 2026 /PRNewswire/ -- Institutional investors holding positions in Immutep Limited (NASDAQ:IMMP) during the period from March 24, 2025 through March 12, 2026 may wish to evaluate lead plaintiff opportunities in a pending securities class action. Request an institutional investor loss assessment. You may also contact Joseph E. Levi, Esq. at jlevi@SueWallSt.com or (888) SueWallSt.
Immutep ADRs lost approximately $2.28 per share in a single trading session on March 13, 2026, an 83% decline, after the Company disclosed that its pivotal TACTI-004 Phase III clinical trial was recommended for discontinuation due to futility. The Court has set July 6, 2026 as the deadline to apply for lead plaintiff appointment.
Notice to Institutional Holders
Pension funds, mutual funds, endowments, and other fiduciaries that held IMMP positions during the Class Period face a dual obligation: assessing whether their beneficiaries suffered compensable losses and evaluating whether active participation in this litigation serves their duty of prudent management. With 1.4 billion ordinary shares outstanding as of June 30, 2025, institutional holders likely represent a significant portion of the affected class.
ERISA and Fiduciary Considerations
Fiduciaries who held IMMP in retirement plan portfolios should evaluate whether the securities class action presents a recoverable asset for plan participants. The lead plaintiff role in federal securities litigation offers institutional investors direct oversight of case strategy, settlement negotiations, and counsel selection.
Portfolio Impact Assessment
The lawsuit contends that throughout the Class Period, Immutep's senior management issued statements touting "strong operational progress" and "encouraging support from investigators" for the TACTI-004 trial while allegedly concealing internal data indicating a materially increased risk the study would fail its primary endpoints. When the Independent Data Monitoring Committee recommended discontinuation for futility on March 13, 2026, the resulting price correction eliminated the vast majority of shareholder value overnight.

Case Summary
The securities action asserts that Defendants made false and misleading statements about the efficacy, safety, and prospects of eftilagimod alfa in the TACTI-004 study. The complaint alleges Defendants had access to internal clinical data and interim analyses that contradicted their public optimism, yet continued issuing positive projections through February 2026, just weeks before the trial was halted.
