Although the scheme had irrevocable support from institutions with a combined 70%, some of the smaller institutions are reported to have sold out to CBH. With just more than 25%, CBH can block the scheme, which needs the support of 75% of shareholders.
The meeting, scheduled for July 25, will vote whether to implement a proposal that would introduce black economic empowerment (BEE) shareholders to Sovereign.
Tuesday is the last day to trade to be able to vote at the Sovereign meeting. But even if CBH succeeded in cancelling or delaying the scheme meeting, it might have to sweeten its offer if it wants to gain control of Sovereign.
