After the recent termination of Selen Tatsuki's contract and the following public backlash, it has become obvious that Nijisanji EN's management is incompetent at best and malicious at worst. It is very likely that recent graduations and terminations won't be the last ones this year.

Note that the first answer is 3, not 0. That's because I included Kyo Kaneko, Pomu Rainpuff and Selen Tatsuki, who have graduated/had their contracts terminated in 2024.
