Can the owners' committee issue bid-winning notices to a number of property service companies? Why? Thank you, it's urgent

Does the bid-winning notice say that only one property company has won the bid? If so, the owners' committee can send it to several property companies to inform the winning results. Generally, it only needs to be sent to the winning property company. Other companies only need to make a phone call or issue a bid-winning announcement on the bidding website. I don't know if this is the case.
