Guardian Pharmacy Services announced on June 2 that it is expanding its footprint into the Pacific Northwest with the acquisition of Mercury Pharmacy Services. This acquisition marks Guardian’s first pharmacy location in Washington.
Mercury Pharmacy Services is a long-term care (LTC) pharmacy based in Mountlake Terrace, Washington. Founded in 2001, Mercury Pharmacy Services is among the largest providers of LTC pharmacy services in the Seattle-Tacoma MSA and serves residents and LTC communities across the state of Washington and adjoining areas.
Headquartered in Atlanta, Guardian Pharmacy Services is one of the nation’s largest LTC pharmacy companies. Guardian’s pharmacies provide client services and resident care to LTC communities, including assisted living and skilled nursing, group home, behavioral health and to organizations that serve individuals with intellectual and developmental disabilities. It was founded in 2004.
All existing leadership and staff at Mercury Pharmacy Services will remain in place following the acquisition, continuing to operate under the same name.
This marks Guardian’s second transaction of 2025. In May, the company acquired Senior Care Pharmacy, an LTC specialty pharmacy based in Wichita, Kansas. Guardian also acquired Midwest LTC Pharmacy in July 2022, and Freedom Pharmacy in December 2024.
As with Guardian’s other acquisitions, Mercury Pharmacy Services will benefit from the company’s unique business model. This enables the local pharmacy teams to focus on customer service and the specialized needs of the communities and residents they serve, while Guardian’s centralized Corporate Support Team assists with the many complex behind-the-scenes business functions, including data analytics, HR, IT, payor relations, national sales and more. Financial terms of the deal were not disclosed.
According to data in the LevinPro HC database, this transaction marks the 15th Specialty Pharmacy transaction of the year. There were 28 Specialty Pharmacy acquisitions reported in 2024, and 15 reported in 2023.
