While acceptances had only reached 61.75 per cent by 9am on March 12 the company had previously said it was happy to take less than the 75 per cent.
Just a day later and acceptances rose to 73 per cent and yesterday hit 86 per cent - well in excess of the target and a result which will now require scaling.
It seems Restaurant Brands shareholders didn't take up the offer until late in the piece, with 41 per cent formally behind it at the end of last week and only 28 per cent the week before that.
The Finaccess offer values Restaurant Brands at $1.18 billion and was a 24 percent premium to the $7.60 share price the company was trading at before the bid emerged.
Restaurant Brands shares closed at a record high of $9 on Wednesday.
