Niron Stabinsky, Credit Suisse Group AG‘s head of special purpose acquisition companies and permanent capital, is reportedly leaving Credit Suisse to join Banco Santander SA, as reported by Bloomberg News.

Stabinsky was dubbed “Mr. SPAC” during the two-year surge of blank-check ventures that began in 2020. He has advised dealmakers such as Chamath Palihapitiya, Todd Boehly, Bill Foley and Chinh Chu. Ryan Kelley, a Credit Suisse director, will also join Stabinsky at Santander, Bloomberg reported.

Santander has hired multiple bankers from Credit Suisse as uncertainties loom around the UBS Group AG merger brokered by the Swiss government.
