Hookipa Biotech Wins Best Financing Deal Award in the Vaccine Industry Excellence (ViE) Awards 2014

Vienna Austria, 31 March 2014 - Hookipa Biotech AG, a company pioneering a new class of
vaccines, is pleased to announce that it was the winner of the Best Financing Deal Award in the
Vaccine Industry Excellence (ViE) Awards 2014, as part of VaccineNation and the World Vaccine
Congress in Washington D.C. last week.

The Award was in recognition of Hookipa’s €20 million ($27.6 million) Series B financing closed in
October 2013. Existing investors Sofinnova Partners and Forbion Capital Partners led the financing
with new investors Boehringer Ingelheim Venture Fund, Takeda Ventures and BioMedPartners
joining the round.

Accepting the award, Dr. Katherine Cohen, Chief Executive Officer of Hookipa Biotech said: “We are
delighted that our successful financing round has been recognized in this way. Funds raised have
been used to progress our viral vaccine pipeline and to explore applications in cancer

“I would like to thank our investors for their continued support of Hookipa and I look forward to our
continuing collaboration during our exciting next stage of development” she said.
Hookipa has developed Vaxwave®, a novel and proprietary viral vector platform with exquisite
capacity for the stimulation of antibody and CD8+ T cell immunity. The Company’s lead product
candidate based on this platform, HB101, is a vaccine against cytomegalovirus (CMV) that is currently
in advanced pre-clinical development and testing. The new investment will be used to progress
HB101 into Phase I clinical testing and to further industrialize Vaxwave® technology, both for
partnering and for building a robust product pipeline in the area of infectious diseases and cancer.
Hookipa’s Vaxwave® technology exhibits great potential for cancer immunotherapy, since Vaxwave®
vectors are not inhibited by anti-vector immunity and can be repeatedly administered for stimulating
potent CD8+ T cell responses against tumor targets. The series B financing will thus also be used to
explore applications for novel cancer therapies.

Other finalists were Immatics, Madison Vaccines, Vaxess Technologies and PaxVax.
