Basking Ridge, N.J., [October 11, 2017] – Ipsen, (Euronext: IPN; ADR: IPSEY) a global
biopharmaceutical company, today announced that it has joined the Pharmaceutical Research
and Manufacturers of America (PhRMA), one of the most influential industry trade associations in
the United States. As a member of PhRMA, Ipsen will gain ongoing access to like-minded
industry partners and advocacy organizations at the federal, state and global level, who are
equally dedicated to researching and developing new, cutting-edge therapies for patients.
Simultaneous to the approval of Ipsen’s membership, Ipsen Chief Executive Officer David Meek
will join the Board of Directors of PhRMA.

“We are proud to continue our work with PhRMA, as we are aligned with the organization’s
mission of encouraging the discovery of bold new advances in treatments and cures for patients
through ongoing partnership and collaboration,” said David Meek, Chief Executive Officer, Ipsen.
“Through our research and development efforts, we are continuing to advance treatment options
for patients by focusing on scientific innovation and development activities across our core
therapeutic areas of oncology, neurosciences and rare disease.”

In May 2017, the PhRMA Board of Directors established new criteria for membership, specifying
that biopharmaceutical companies would have to meet new R&D requirements to be eligible to
join and/or maintain a membership with PhRMA. These include a three-year average global R&D
to global sales ratio of 10 percent or greater and a three-year average global R&D spend of at
least $200 million per year. Ipsen Biopharmaceuticals, which had previously been an associate
member beginning September 2012, satisfies these new R&D-based criteria.

“We are pleased to welcome Ipsen into our membership. Our members are at the forefront of the
most exciting science and research occurring in the biopharmaceutical industry,” said President
and Chief Executive Officer of PhRMA Stephen J. UbI. “We look forward to Ipsen’s continued
participation in our efforts to advance policies that will help us achieve our goals of modernizing
the drug discovery and development process, advancing value-driven health care, ensuring
patients benefit more from negotiated discounts and addressing market distorting programs.”

In addition to membership with PhRMA, Ipsen also holds longstanding relationships with a
number of associations in North America, including the National Pharmaceutical Council,
Organization for International Investment, Innovative Medicines Canada, BioNJ and
Massachusetts Biotechnology Council.
