Red Bull are poised to make two dramatic announcements over the next two weekends, we can exclusively reveal. At next weekend’s Bahrain F1 race, the Austrian energy drink firm will announce its withdrawal from the premier four-wheeled racing series at the end of 2014.

A week later, at the Austin MotoGP round for which it is the title sponsor, Red Bull is to announce that it is to purchase Bridgepoint Capital’s remaining stake in MotoGP, and take over the running of the series.

Sources in the private finance industry with knowledge of the situation say that Bridgepoint has been looking to rid itself of its motorcycle racing business for some time. The private equity firm had acquired 71% of Dorna in 2006, at the peak of MotoGP’s popularity, reputedly for £400 million.

Since then, they have seen the value of their investment drop, and have been looking to get their money back from the deal ever since. The sale of a 39% stake in Dorna to the Canadian Pension Plan Investment board was the first step in recouping their investment.

That deal was rumored to be worth €400 million, or just over 70% of their initial outlay. Sources with knowledge of the situation say that Red Bull is to acquire the remaining 32% of Dorna for around €300 million , but with full control over the series.
