Joele Frank and Brunswick Group are working Kroger's $24.6B acquisition of Albertsons to create a supermarket chain that spans the US.
The combined entity will have about 5,000 stores and 700K employees.
Kroger's family of companies includes Ralph's, Fred Meyer, Food 4 Less, Kroger, Pay-Less Super Markets, King Scoopers, Dillons, City Market, Pick' n Save and Fry's.
Albertsons' brands include Safeway, Vons, Jewel Osco, Shaw's, Acme, Albertsons, Kings, Lucky and Tom Thumb.
The deal joins two "purpose-driven organizations to deliver superior value to customers, associates, communities and shareholders," said Kroger CEO Rodney McMullen.
He said the addition of Albertsons "advances our commitment to build a more equitable and sustainable food system" and "accelerates our position as a more compelling alternative to larger and non-union competitors."
Joele Frank, Wilkinson Brimmer Katcher's Steve Frankel, Mahmoud Siddig, Tim Lynch and Lucas Pers handle Kroger.
Brunswick Group's Jayne Rosefield, Matt Dowe and Dave Carlson represent Albertsons.
