A press conference has been called for 11.30am on Friday when details of GFH Capital's reported £52million takeover are set to be spelled out.
A statement on Leeds' website confirmed the Dubai-based investment company would take 100 per cent charge, with GFH deputy chairman David Haigh, who became a director last month, to be joined on the board by fellow executives Salem Patel and Hisham Alrayes.
"We are delighted, but also honoured and proud to be the new owners of Leeds United football club," Haigh said.
"We have had over 4,000 e-mails of support from fans and we have been overwhelmed by the reaction.
"Everyone we have spoken to in the city has been fantastic."
GFH has been in protracted talks with Ken Bates, who is relinquishing ownership, over a deal that Patel believes can reinvigorate the club.
Leeds have been outside the top-flight since 2004 following financial turmoil that, at one point, instigated a fall into the third tier.
GFH has previously stated a desire to take the club back to the top-flight and Patel added: "We are looking forward to a bright future.
"This is a fresh start for the football club and we welcome fans both old and new to Elland Road."
