She is rebating 50% of her commission (referral payment) to the buyer through escrow. Does she still needs to 1099 the buyer?

My wife is a buyer's agent.  Since this is a new home build her buyer is purchasing.  She is paid a referral fee instead.  She is returning 50% of her commission to the buyer via escrow.    Does she need to 1099-MISC for the rebate?   This is similar to the below except because it's a new home, her role is a "referring agent" instead of buyer's agent.
