There is no hard and fast rule on it. Bosch own 76% of Pacifica due to minority shareholders blocking a full takeover & it's still listed. Cleveland Cliffs owned 85% of Portman before many months later making a higher offer to buy out the minorities & it was still listed even though Cleveland owned 85%.

Stop getting too excited. These things take months, if not years to sort out
