L’Oreal has signed a final agreement with Nestle, for the sale of its stake in Galderma. It’s a step toward L’Oreal ultimately being able to buy back an 8% stake in the company, from Nestle.

L’Oreal’s board of directors approved the sale last week. The two companies came to the agreement last month – for L’Oreal to buy back for 6.5 billion euros ($9 billion) an 8 percent stake held by Nestle in Galderma. The deal allows both companies to boost earnings per share.
