Charlton remain in discussions with a group of Dubai-based investors over a potential multi-million pound takeover of the Coca-Cola Championship club.
The Addicks were last week the subject of an indicative offer from Zabeel Investments - recently linked with buying Newcastle - but the Athletic board have now urged supporters to be patient as they await a possible cash windfall.
Charlton plc chairman Derek Chappell told the club's official website: "We are of course very aware that supporters are desperate to know more, but I'm afraid there are strict regulations that we must adhere to at the present time."
He added: "A confidentiality agreement has been signed between all parties, and we cannot contravene that.
"I'm not one for using the phrase 'no comment' as I usually have plenty to say in heading up the club, but we have rules to follow in the current situation.
"Like myself, Alan cannot respond at all to questions on company issues for the moment, but I'd like to reassure fans that we will relay any new information to them as soon as we are permitted to."
