Altria Group Inc. said Friday it has agreed to sell its Ste. Michelle Wine Estates business to private-equity firm Sycamore Partners Management L.P. for about $1.2 billion in cash. Altria expects the deal to close in the second half of 2021. The deal is expected to allow the company focus on its transition to non-combustible products. Proceeds will be used to fund share buybacks, subject to board approval.
