After months of discussions, the Birmingham-based company bought out previous majority shareholders Brabco, who have been involved with the Scottish League One club since 2008.
In that time the Sons made it from the old Third Division all the way to the Championship, though they’re in real danger of dropping back down into the bottom tier again at the end of this season as Jim Duffy’s men sit just two points above Clyde in the relegation play-off spot with just two games to play.
A statement on the club’s website read: “Dumbarton FC can announce that a deal has been concluded today for Cognitive Capital Ltd to buy out Brabco's majority shareholding in the club.
“We had been in discussions with Cognitive Capital Ltd for some time and we look forward to working with them as our majority shareholder.
“The group has significant plans for the club which we look forward to embracing in the weeks and months to come.
“We wish to thank Brabco for their valued involvement with us over the years.
“We will keep our supporters fully informed of plans for the progress of the club.”
It remains to be seen whether the new investors will follow Brabco by looking to move the club away from the Dumbarton Football Stadium (known as C&G Systems Stadium for sponsorship reasons) despite the ground only being constructed in at the beginning of this century.
