The UK's takeover panel said on Tuesday that plastics maker Berry Global Group now has until 13 March to announce a firm intention to make an offer for British packager RPC Group.
Berry Global said last month it was considering a cash offer for RPC, in a challenge to a £3.3 billion (€3.8 billion) bid from the US company's former parent, Apollo Global.
RPC, Europe's biggest plastic packaging company, said on Tuesday it continues to engage with Berry, but did provide any further details.
In February of this year, the group posted third quarter revenues of £894 million (€1.02 billion), and an organic growth of 1.4%. Organic growth for the first three quarters, to 31 December, was 2.6%.
