(Adds confirmation from M&B on talks, background, updates share movement)
May 29 (Reuters) - British pubs group Mitchells & Butlers said on Thursday that it was in exclusive talks to acquire a majority of the pubs owned by rival Orchid Group.
The operator of pubs such as All Bar One did not divulge any additional details on the deal, but The Times reported late on Wednesday that M&B had offered to pay more than 250 million pounds ($418 million), outbidding private equity firms Colony Capital and Starwood Capital.
The company is buying about 170 to 180 of Orchid's 220 pubs, with the balance expected to be tipped into administration with consultant EY, the newspaper reported.
M&B, which operates around 1,600 restaurants and pubs in the UK, is understood to have offered 266 million pounds, although the final price is likely to be about 256 million pounds after adjusting for working capital in the business, The Times reported.
"We believe the deal is a good one for M&B, at a price it can comfortably afford," Numis Securities analysts said in a note, adding that the deal could increase M&B's earnings by 7 percent to 9 percent.
The newspaper said M&B was thought to have offered about 10 million to 15 million pounds more than Colony Capital, the underbidder, with Starwood Capital a little lower still.
British brewer Greene King pulled out of takeover talks last week, saying the transaction did not meet the company's strict acquisition criteria.
Orchid is owned by a trust linked to Deutsche Bank .
