BNB was 100% pre-mined, I believe, but the "cap" was at the 200 million token limit, with half of the pre-mined coins sold to the public (ICO).
So while they can't just print more, they can donate from their own stash, either from accumulated profits (which would have been added to their corporate treasury), or from part of their stash that wasn't already circulating.
But it is only $5M worth, ... nothing really that will push down the price by any noticeable amount.
