Chemical giant Ineos is to become a one-third shareholder in the Mercedes Formula 1 team.
It will have an equal shareholding with Mercedes parent company Daimler and Toto Wolff, Mercedes motorsport boss and F1 team principal.
The move reduces Daimler's shareholding from 60% and ups Wolff's from 30%.
Wolff, in charge of Mercedes F1 operations since 2013, has signed a new contract and will remain team boss and chief executive for three more years.
The 48-year-old "will have the subsequent opportunity to transition to a new executive function within the organisation when he decides it is the right time to do so," a statement said.
The statement added that Mercedes F1 would "remain the works team of Mercedes-Benz and will continue to race Mercedes chassis and power units in the coming years".
