Wycombe Wanderers managing director Steve Hayes is the new owner of the club after fans voted to hand over control to him.
Hayes previously owned 25% of shares in the club, but had to rely on a change in the club's constitution to complete a takeover at Adams Park.
The millionaire businessman also owns rugby club London Wasps, who groundshare with Wycombe.
He is expected to step up his plans for a new stadium for both clubs to share.
The Supporters' Trust had recommended acceptance of Hayes' proposals, ahead of the general meeting on Monday.
The founder shareholders voted 81% in favour of his £3m bid and they, and the shareholders then followed up with a 99% vote in favour.
Hayes has ploughed almost £7m into the club in the form of loans, and warned fans that he would stop funding the club if they voted against his plan.
Club directors warned that voting no would result in the club going into administration and being docked 10 points.
Hayes said: "I am delighted and very proud to assume ownership of this great club.
"I asked for the backing of the shareholders and I received it. I appreciate that the result wasn't to everyone's liking, but now we need to move on.
"There seem to be so many different factions amongst our supporters. Some fans just want to watch their team play and then go home without having any further involvement and I fully understand that.
"But there are others who continually choose to criticise the club on web forums without offering any practical solutions to move the club forward.
"I would love to see everyone pulling together in the same direction. I know that there are many who want to help the club and we want to talk to and listen to those supporters."
