International Distribution Services (IDS), the parent company of Royal Mail, is valued at £3.5 billion in the most recent bid from Mr. Kretinsky’s investment firm, EP Group.
As a 27.6% shareholder, Mr. Kretinsky’s company currently owns the majority of IDS, but it wants to purchase the remaining shares.
Last month, an earlier offer of £3.20 per share was turned down because it was too low.
However, he has now made a share offer of £3.60. IDS shares cost £2.14 the day before the original offer was made.
In the event that the transaction succeeds, EP Group has proposed an additional shareholder dividend of 8 pence per share in addition to a 2 pence per share.
