SoftBank Group Corp.’s global head of communications Gary Ginsberg has left the company after two years on the job, another in a string of high-profile departures.

Ginsberg resigned in December, a spokesperson at SoftBank said, confirming the change that was never made public. Sarah Lubman, who was hired by Ginsberg in 2019 from Brunswick Group, has stepped in as acting chief of communications.

Masayoshi Son’s conglomerate has lost a number of senior executives over the past several months. Chief Legal Officer Rob Townsend and Chief Compliance Officer Chad Fentress both resigned last year, while Chief Strategy Officer Katsunori Sago is leaving at the end of March after less than three years at the company. The Vision Fund, SoftBank’s mammoth venture capital unit, recently lost two managing partners in Colin Fan and Jeff Housenbold, Chief Operating Officer Ruwan Weerasekera, and its head of investor relations Penny Bodle.
