More or less by definition, this won't impact their yearly bottom line by more than 0.3% (at least to within first order). Which is quite a bit, but it still seems super minor. Just like 2 million. Isn't that peanuts for a stock exchange?
However, you see, TSE YoY growth from 2017 to 2018 is roughly 4 million USD. Growth is hard as it is for TSE, leaving money on the table like this time definitely hurts.
