I should do deep DD? Ha I apparently understand zentek and companies like it more than you do. Of course they don't have to buy any shares back duh. but then that makes this is a silly fake buyback. You think institution buyers like companies that do fake buybacks? if zentek bought shares it would make their cash even lower after Greg said they were being disciplined with cash. why isn't zentek focused on contracts instead of this stuff.
You should inform yourself better before commenting, go talk to institutional investors and educate yourself.
