Speculation linking Michael Andretti and his similar operation to the purchase of the Sauber Formula 1 team persists.
The US organization has long been associated with a switch to F1 with reports that an agreement worth 350 million euros is approaching.
RaceFans has reported that Andretti was able to buy 80 percent of the shares in Islero Investments, giving him control of both Sauber Motorsport and Sauber Engineering.
Islero Investments was created by Longbow Finance, which bought the team from Peter Sauber and Monisha Kaltenborn in 2016.
The company’s Formula 1 operation has been renamed Alfa Romeo in recent seasons, but behind the scenes it is the Sauber F1 team.
Speaking in Turkey on Friday, team manager and CEO Frederic Vasseur distanced himself from questions about the potential buyout of the team.
“I can not say anything, because it is honestly not in my parameter,” he said.
“I’m the CEO and the team manager, and this kind of discussion is not with me, it would be with the shareholders, and we had so many rumors, and so you have to ask the question to the company’s shareholders.”
Andretti Autosport presented four full-time cars in the IndyCar series this year, plus additional contributions to Marco Andretti and Stefan Wilson at the Indianapolis 500.
Colton Herta was best placed by his regular runners and took three victories to finish in fifth place in the standings.
Last month, it announced that former Formula 1 driver Romain Grosjean would join the team in 2022.
It also has interests in junior categories in the United States and has a stake in the Walkinshaw Andretti United operation in Supercars.
The squad has not publicly commented on the prospect of acquiring Sauber other than confirming that F1 is of interest to Michael and the team.
“Getting into Formula 1 has been interesting for Michael and the team for some time and we have explored many options over the years, but at the moment we have nothing new to report,” the team has claimed.
“Our passion is racing, in all forms, and we never say never.
“Should there be a proper opportunity to take the Andretti name back to F1, we would jump at it.
“But from now on, this opportunity has not fallen into our lap and our focus remains on our seven competitive disciplines.”
Valtteri Bottas was last month confirmed as a member of the Alfa Romeo Sauber team in 2022, although the identity of his teammate has not yet been confirmed.
