Founded in 1981, Whole Health provides primary care, urgent care, wellness programs, health coaching and occupational health services for 27 clients. Walgreens estimates that the current potential market for worksite health centers and pharmacies includes more than 7,600 corporate campuses of 1,000 employees or more. "The story here is growth, and as these two companies increase their offerings, we can expand our complementary services more quickly and to a larger market," stated Jeff Rein, Walgreens chairman and chief executive officer. "I-trax and Whole Health also will open the door for us to add worksite pharmacies where they already operate health centers. This is a natural extension of the existing worksite pharmacy services we currently provide for such companies as Sprint, ABX Air and Toyota." Under the agreement, Walgreens will buy I-trax for about $278 million in cash, including the assumption of about $18.3 million in net debt.
