The fact that things like merchandising are being included when talking about it making a profit show the problems this film has experienced. A film should never be reliant on merchandising to when it comes to breaking even, most films don't get that benefit of merchandising, they have to pay for themselves. Merchandising is the cherry on top, that extra bonus that turns movies from profitable to very profitable. You also need to factor in that often the merchandising is done by another part of the company, so while it all still goes to WB it probably won't end up in the books of the division that made the movies.
