Lion Nathan has announced it is making an off-market bid for the Adelaide-based brewer Coopers.
It is offering $260 a share for each class of Coopers shares, valuing the family-owned company at $352 million.
The chief executive of Lion Nathan, Rob Murray, says the offer represents a premium of 478 per cent based on the price of a buy-back conducted by Coopers in 2003.
Last month, Coopers mounted an action in the South Australian Supreme Court aimed at thwarting any predatory intentions by Lion Nathan.
Coopers wants a change to its constitution to block Lion Nathan from exercising a third-tier right of refusal for Coopers shares.
Currently, if a Coopers shareholder offers shares for sale and they are not taken up by another Coopers shareholder nor AMP, then Lion Nathan has the option to acquire them.
Coopers managing director Tim Cooper says the board will meet to give the offer due consideration.
"We strongly recommend our shareholders take no action until they've heard back from the board after the board gives its consideration to the offer," Dr Cooper said.
