The regulator approved the deal — announced last month during the coronavirus pandemic — on Friday and the company is expected to close on it in the coming days, sources said.

Regulators had been reviewing the acquisition to be sure it wouldn’t reduce competition. PepsiCo owns Mountain Dew Kickstart and is also a partner in Starbucks energy drinks.

But Rockstar’s market share has fallen in recent years from almost 20 percent to less than 10 percent, which helped alleviate the FTC’s concerns, a source said. Rivals include Red Bull and Monster, which are part-owned by Coca-Cola.

Rockstar founder Russell Weiner, son of conservative talk show host Michael Savage, is not expected to play a big role under the new ownership, the source added.

The deal also opens the door to Pepsi introducing new energy drinks, sources said. As Rockstar’s distributor, PepsiCo had been barred from developing competing brands.

Mountain Dew’s Kickstart, while often is considered an energy drink, is advertised as a breakfast beverage and has less caffeine than products like Red Bull.

The FTC did not return calls.
