The increase also came after a valuation exercise by St Modwen came in with a higher net asset value than at the time of the previous bid. On a per share value, the NAV is now 463p where before it was 427.7p
In terms of the premium to net asset value, the bid is at a similar multiple to the previous offer of 21%.
