Lysogene is Joining the Euronext’s Indexes CAC® Small, CAC® Mid & Small and CAC® All-Tradable

CAMBRIDGE, Mass. & PARIS--(BUSINESS WIRE)--Regulatory News:

“Lysogene’s inclusion in these CAC® indexes is an excellent event for our stock market listing and a new stage in our development, providing it with increased visibility among both French and international investors.”

Lysogene (Paris:LYS) (FR0013233475 – LYS), a pioneering biopharmaceutical company specializing in gene therapy targeting central nervous system (CNS) diseases, announces that, as of June 15, 2018 after markets close, it will be included in three new CAC-family indexes: CAC^® Small, CAC^® Mid & Small and CAC^® All-Tradable.

The inclusion of Lysogene’s shares in these indexes follows an analysis of the share by Euronext based on its free float market cap and illustrates investor interest in Lysogene. The Company has entered 2018 with significant momentum to achieve key clinical development and regulatory milestones across its portfolio of gene therapy products for neurological diseases. Lysogene has secured recently a collaboration agreement for the development of an AAV-based gene therapy for Fragile X syndrome, the most common genetic cause of autism, a condition of high-unmet medical need.

The Euronext Paris Indexes’ Scientific Committee took this decision during its quarterly review of these indexes on June 7, 2018.

Karen Aiach, CEO and Founder of Lysogene says: “Lysogene’s inclusion in these CAC® indexes is an excellent event for our stock market listing and a new stage in our development, providing it with increased visibility among both French and international investors.”
