The Issa brothers and TDR Capital will offload Asda's petrol stations to their own EG Group for £750m when their purchase of the UK supermarket group from Walmart is completed.
Zuber and Mohsin Issa and private equity firm TDR Capital in October agreed to buy a majority stake in Asda from Walmart in a deal which gave the group an enterprise value of £6.8 billion.
Separately, the brothers and TDR own EG Group, a global convenience and petrol forecourts retailer which trades from more than 6,000 sites across 10 countries.
There has been speculation EG Group could pursue a stock market listing.
The brothers and TDR said the Asda acquisition was on track to complete later this month.
However, it remains subject to clearance from the UK's Competition and Markets Authority (CMA) which is expected in the second quarter of 2021.
They said the petrol forecourts deal, under which the stations will continue to be branded Asda, will be considered by the CMA as part of its review of the Asda purchase.
The Issa brothers and TDR said they also plan to sell some of Asda's distribution assets to institutional real estate investors. Asda would continue to operate the assets.
As part of the financing of the Asda deal, the brothers and TDR plan to raise £840m of loan facilities, £2.25 billion of senior secured notes and £500m of senior notes.
They have committed to invest £1 billion in Asda over the next three years.
Asda, Britain's third biggest grocer after market leader Tesco and Sainsbury's, said its sales rose 6.9% over the eight weeks to December 24.
All of Britain's supermarket groups enjoyed strong Christmas trading, with coronavirus restrictions closing the hospitality sector and forcing many people to work from home.
