0619 GMT - Nestle's $1 billion deal to sell its mainstream vitamins, minerals and supplements business to private-equity group Yellow Wood Partners should result in a minimal dilution of the Swiss food giant's earnings, J.P. Morgan analysts say in a research note. The business generated roughly 1.1% of Nestle's sales last year and was a lower-margin part of the group's portfolio, according to JPM. Nestle will keep premium vitamins, minerals and supplements brands like Solgar and Pure Encapsulations. "The combination of the mainstream and premium [vitamins, minerals and supplements] businesses brought scale and breadth of brands that had manufacturing and [route-to-market] synergies that have since become less relevant, and Nestle has emphasized the strong performance of the premium [vitamins, minerals and supplements] business," the analysts say.
