Staprix NV, owned by Belgian businessman Roland Duchatelet, have successfully completed the takeover of Sky Bet Championship club Charlton.
Chairman Michael Slater, Tony Jimenez and Martin Prothero will step down from the club's board of directors.
"In every important respect we leave the club in a far better state than when we took over three years ago, but now is the time to pass the baton to Roland who has a proven track record of success in business and football.
We believe we have found an investor with extensive knowledge of football who is well placed to stabilize the club in the Championship and help the club to develop on a sensible commercial basis."
Ahead of the new football season, Charlton have signed Bolton striker Marvin Sordell on loan for the season. He played for England at the recent European Under-21 Championships as well as for Team GB at last year's Olympics.
He'll be joined at The Valley by former Reading striker Simon Church who's agreed a two-year contract. Church has played 22 times for Wales. Charlton start their season on Saturday away to Bournemouth.
Charlton are confident their game against Sheffield Wednesday will go ahead on Saturday after fans volunteered to help clear the snow from the pitch. Around 20 supporters turned up today at The Valley and cleared the pitch with shovels.
Groundsman Colin Powell said: "We're a unique club. We moved away from here for 5 years and the fans got us back so you expect them to come down now and they're brilliant."
Charlton supporters are smiling again after their team won promotion to the Championship with a 1-0 win at Carlisle.
Bradley Wright-Phillips fired them to victory with the only goal after 76 nervous minutes at Brunton Park to ensure the League One leaders now have an unbridgeable 10 point advantage over third-placed Sheffield Wednesday with three games to play.
