Business Wire

SAN DIEGO -- April 30, 2013

Ligand Pharmaceuticals Incorporated (NASDAQ: LGND) has acquired a portfolio of
potential future milestone and royalty payments for more than 15 biologic
development programs from Selexis SA. Each acquired program is fully funded by
a development partner. Geneva, Switzerland-based Selexis is a privately held
global life science company focused on drug discovery for lead identification
and cell line development for scale-up and manufacturing of therapeutic
protein drugs.

The basis for the development programs is Selexis’ proprietary technology
platform for generating stable and high performing manufacturing mammalian
cell lines for biologic therapeutics. The acquired assets include potentially
groundbreaking mechanisms of action of biological drugs and expand Ligand’s
presence in large, growing therapeutic markets such as oncology, inflammation
and autoimmune diseases. The acquired programs are in various stages of
preclinical and clinical development.

“This acquisition significantly expands Ligand’s already robust portfolio to
more than 85 fully-funded assets, and diversifies our portfolio beyond small
molecule therapeutics into biologics,” commented John Higgins, President and
Chief Executive Officer of Ligand. “The acquired rights are a great fit with
our royalty-based business model, and the deal does not require operational
integration or ongoing technical responsibilities from Ligand. We believe this
acquisition reinforces the strength of our shots-on-goal strategy and has the
potential to provide Ligand with numerous new drivers of long-term growth.”
