Blackstone Group is set to acquire 75 of direct-to-consumer genetic testing firm Ancestry from its former equity holders in a $4.7 billion deal.br Ancestry currently generates $1 billion in revenue annually.br It has over 3 million paying consumers.br Consumer demand for DTC genetic tests has been on a downswing since 2019.br Consumer disinterest is likely being compounded by the fact US consumers are spending less amid the pandemic-induced economic slowdown.br A shrinking volume of new customers is likely what led Ancestry to lay off 6 of its staff this year alone.
