Charlton Athletic chairman Richard Murray has completed a share buy-out that will see him take full control of the League One side.
The businessman agreed terms with the other directors for the purchase of shares in the football company and Charlton Athletic Holdings Ltd.
"We will now go forward and actively seek new investment," he said.
"This has been a critical time. Our future was uncertain, and this was potentially one of our darkest hours."
The Addicks have been the subject of speculation of a possible takeover for the past three years with various organisations - but none have come to fruition.
Murray also reassured fans that he has high hopes for the new season ahead.
Following their failure to secure promotion back to the Championship last season, the chairman has not ruled out investing in new talent.
"There is still a lot of work to be done," he continued.
"We intend to be competitive this season, and if we need to pay a small fee to prise one or two people away from their clubs, then we will do that.
"I can assure supporters we're working as hard as we can within the resources we have available."
