In July 2018, we began an exciting transformation to become an independent company under the ownership of KKR, a leading global investment firm based in the United States that builds stronger companies through employee engagement.

We believe an actively engaged workforce — with people acting and being treated like owners — produces a better company for all. So, in February 2019, we introduced the Hyperion Ownership Participation Program, which empowers our employees by allowing them to share in the value we create together.
