But he has yet to hear back from the club and it is thought that a long-term managerial appointment is unlikely until Ashley completes his intended sale of the club.
Ashley, who bought Newcastle in 2007 for £134.4m, has put the club up for sale for a second time and apologised to fans for his "catastrophic" reign in charge of the club.
He is thought to be willing to accept about £80m for the club as he looks for a quick sale.
Shearer added he remains fully committed to the club and denied reports claiming he is set to walk away because of the uncertainty.
"I don't know where that's come from, it's certainly not from myself," said the former Newcastle and England striker. "I want it sorted out as quickly as everyone else does.
"I'm a fan like everyone else and I don't like to see the situation the club is in."
Shearer was speaking ahead of Sunday's charity match between an England XI and an ex-Germany side - to support former Newcastle and England manager Sir Bobby Robson's cancer charity - at St James' Park.
