The Hy-Vee grocery chain is acquiring a specialty pharmacy based in Omaha.

Hy-Vee said Monday that it has agreed to purchase Amber Pharmacy.  Financial terms of the deal were not disclosed.

The employee-owned grocer says the acquisition of Amber will help it expand its pharmacy services for complex cases and for patients dealing with chronic illnesses.

Amber Pharmacy has locations in Omaha, Chicago, Dallas and Philadelphia. It will continue to operate independently of Hy-Vee.
