Pique's investment group Kosmos saw their offer approved by FC Andorra's club members on Saturday, with 206 voting in favour and just one abstention.
The club was founded in 1942 and played as high as Spain's third tier (Segunda Division B) in the 1980s and 1990s, but it now competes against clubs from Catalonia in the fifth tier.
Marca reports that Pique will take over as club president, with former Barcelona players Gabri and Albert Jorquera forming a new-look coaching staff.
"The General Assembly of FC Andorra has unanimously approved the transmission of its assets in favour of an Andorran company jointly managed by different investors, including Kosmos," said a statement from the company.
