Walgreen’s Rite Aid remix may get OK

Walgreen Co. may finally have the right prescription to get its $10 billion acquisition of Rite Aid through federal regulators, The Post has learned.

The $91 billion chain is optimistic the new package of stores it is selling to regional chain Fred’s will be enough to get the Federal Trade Commission to finally bless the deal, a source with direct knowledge of the situation told The Post on Wednesday.

FTC brass in the next two to four weeks will likely approve the deal that would create America’s biggest drugstore chain, two other sources said.

Walgreen, combined with Rite Aid, would have a reported 46 percent US market share. Several years ago, Walgreen acquired New York chain Duane Reade, expanding its local presence.

After getting pushback from the FTC on a smaller package of stores to be jettisoned, this month Walgreen sweetened both the number and quality of stores it will sell, sources said.

Previously, Walgreen had agreed to sell Fred’s 865 stores. It has now promised to sell up to 1,200 stores, sources said.

As a result, Walgreen reworked the sale price in the October 2015 merger agreement to $7 a share from $9.

The price would be cut to $6.50 if regulators forced a sale of more than 1,000 stores, Walgreen said.

Rite Aid shares rose 1.2 percent on Wednesday, to $5.79, while Walgreen gained 46 cents, to $84.25.

Debbie Feinstein, the bureau of competition director for the FTC, would like to get the deal approved before she resigns — likely within weeks, a source said.

Walgreen did not return calls.
