Walgreens reported a better than expected profit on flat sales for its second quarter Tuesday morning and unveiled an expanded partnership with AmerisourceBergen that could give the pharmacy operator an equity position and seat on the drug wholesaler’s board.

Walgreens has formally set up a new company, jointly owned with Alliance Boots, as part of their strategic partnership’s synergy program.

Walgreens on Tuesday announced several new senior management roles, including an expanded role for CFO Wade Miquelon and the appointment of current SVP and chief strategy officer Robert Zimmerman as the lead executive responsible for the Walgreens-Alliance Boots' "synergy team."
