Immutep receives ~A$1.13 million R&D Tax Incentive

SYDNEY, AUSTRALIA - Immutep Limited (ASX: IMM; NASDAQ: IMMP) (“Immutep” or the “Company”), is pleased to announce that it has received a A$1,134,882 cash rebate from the Australian Federal Government’s R&D tax incentive program. The cash rebate provided in respect of expenditure incurred on eligible R&D activities conducted in the 2022 fiscal year, mainly related to the Company’s TACTI-002 and TACTI-003 clinical study using its lead compound eftilagimod alpha (“efti” or “IMP321”), conducted in Australia.

This follows approval from AusIndustry of Immutep’s application for an Advance/Overseas Finding. Due to the Advance Finding, both Immutep’s Australian and overseas research and development activities related to the TACTI-002 and TACTI-003 Australian sites were eligible for the R&D Tax Incentive.

Immutep also receives the French CIR tax incentive through its subsidiary Immutep S.A.S in respect of expenditure incurred on eligible R&D activities conducted in the European Union.

Immutep will apply the non-dilutive funding towards furthering its current active clinical trial programs for its lead product candidate, efti. The expected cash reach of the Company extends into early calendar year 2026.
