Wincanton PLC's (LSE:WIN, OTC:WNCNF) buyer is being probed by the Competition and Markets Authority (CMA) over the near £760 million deal to acquire the FTSE 250 group.
GXO Logistics agreed to buy the haulage group back in February of this year, but the watchdog now wants to check if the deal will lead to higher prices for business customers.
Supermarkets like Asda and Sainsbury's are likely to be asked for their opinions on the deal as part of Wincanton's offering includes moving goods across the country for both.
The CMA will either clear the deal after an eight-week probe or head towards a longer in-depth investigation which lasts four months.
Back in February, Wincanton urged shareholders to accept a lesser offer from French bidder CEVA, until GXO stepped in with a knock-out bid.
GXO’s offer for the group was 26% higher than CEVA's at a £764 million enterprise value taking into account debt obligations.
The offer represented a 104% premium to Wincanton’s closing price on 18 January, when the offer period commenced.
