Madrid (Spain) and Carros (France), February 22, 2021 – Algenex SL, a VC-backed biotechnology company
delivering disruptive technologies for recombinant biologics production, and Virbac, the sixth largest animal
health company worldwide, today announce that they have entered into an international licensing
agreement for the development and commercialization of a CrisBio®-based vaccine in a major swine
indication.

The vaccine will be developed jointly and manufactured using CrisBio®, Algenex’ proprietary and patent
protected Baculovirus vector-mediated expression platform that harnesses the power of insects to act as
natural single-use bioreactors. CrisBio® represents a new paradigm in biologics production, offering a quick,
linearly scalable solution to meet the global demand for recombinant protein production without significant
capex investment. Algenex anticipates receiving European approval of the first veterinary vaccine produced
using CrisBio in 2021.

“This new collaboration with Virbac, one of the global leaders in animal health, is another important
milestone for Algenex and a further validation of our unique CrisBio® technology and its potential to
transform vaccine production in major indications across animal health,” said Claudia Jiménez, CEO of
Algenex.

“With this partnership, we will benefit from the experience of Algenex, and by providing a simple, scalable
and cost-effective alternative to current bioreactor-based expression technologies on the market, we should
be able to increase our footprint in the farm animals’ vaccine market” said Sébastien Huron, CEO, Virbac
group.

Commercial and financial terms of the agreement were not disclosed. The agreement covers all global
markets excluding Poland and Italy.
