Global investment holding company Tennor agreed a deal with the Longines Global Champions Tour (LGCT) and Global Champions League (GCL) to purchase a stake held by American businessman Frank McCourt.
Tennor, founded by German entrepreneur Lars Windhorst, will take over the shareholding of McCourt Global.
McCourt, a former owner of the Los Angeles Dodgers Major League Baseball franchise, had acquired a 50 per cent stake in the GCT in June 2014.
"I am happy to confirm agreement has been reached for our new partnership," said Jan Tops, LGCT founder and President.
"Our business is in good shape and as strong as it always has been, pandemic notwithstanding, and all team owners and other key stakeholders are fully committed.
"We will continue to build on our innovation roadmap and the global success of our circuit.
"We will go forwards not backwards."
LGCT brings together the top 30 riders in the International Equestrian Federation (FEI) jumping world rankings, while the GCL is the corresponding team event.
"I am delighted to have agreed the new partnership with Jan and I look forward to working together to develop exciting opportunities for this fantastic global sports property," said Windhorst.
Tops, who earned a team jumping gold medal at Barcelona 1992, also provided an update on the impact of the coronavirus pandemic on LGCT and GCL.
"We all recognise this will be a period of constant adjustment and adaptation and we will decide very soon if it is possible to safely organise some events this year taking into account the rules of national Governments or whether we will start fresh next year," he said.
"We are looking forward to a positive outcome."
