Bury are facing expulsion from the English Football League after the company attempting to buy the club, C&N Sporting Risk, said it was unable to proceed with its takeover, reports BBC Sport.
The League One Shakers had been given until 17:00 BST on Tuesday to complete the deal.
Bury would become the first team to drop out of the EFL since Maidstone's liquidation in 1992.
The EFL said it "continues to be in discussions" ahead of the deadline.
"The league announced at the weekend that it was working exclusively with the club and C&N in an attempt to finalise a change of control at the club," the governing body said in a statement.
"However, following a period of due diligence, C&N have opted not to progress matters.
"The league continues to be in discussions with Bury FC in advance of today's 5pm deadline and will provide a further update as appropriate."
