Guardian Pharmacy of South Carolina Opens New Headquarters in Charleston to Support Statewide Growth

Winyah Pharmacy and Preferred Care Unite Under New Name and Relocate to Larger, High-Tech Facility to Better Serve Long-term Care Customers across the Palmetto State

Winyah Pharmacy and Preferred Care, members of Guardian Pharmacy Services, Inc. (NYSE:GRDN), one of the nation's largest and most innovative long-term care (LTC) pharmacy services companies, today announced the opening of a new, state-of-the-art headquarters in Charleston, S.C. As part of the relocation, the two pharmacies will merge, rebrand and operate under the name Guardian Pharmacy of South Carolina.

The new building – nearly double the size of the pharmacies' previous Georgetown and Hollywood locations combined – brings all employees and resources under one roof to better serve the growing customer base. This move strengthens Guardian Pharmacy of South Carolina's presence statewide, enhancing its ability to provide high-quality pharmacy services to residents in assisted living, skilled nursing and behavioral health communities, as well as individuals with intellectual and developmental disabilities throughout South Carolina.

"Our previous locations served us well, but with the pace of our growth, we needed a larger space to house all of our employees – with a layout, technology and amenities designed to strengthen our operations and help us continue delivering the LTC pharmacy services our customers count on," said David Whitlock, president of Guardian Pharmacy of South Carolina. "Rebranding under one name reflects our statewide footprint and unified commitment to LTC communities across South Carolina, and this new facility puts us in a strong position for continued growth."

The facility is purpose-built to meet the unique needs of LTC customers. It features cutting-edge technology and advanced automation systems, including robotic dispensing machines, to help staff accurately and efficiently prepare residents' medications. The building also has an IV infusion therapy suite, bringing previously outsourced services in-house to expand offerings for skilled nursing facilities, and tech-enabled continuing education rooms for pharmacy and community staff training.

All employees from the previous locations are included as part of Guardian Pharmacy of South Carolina's team at the new headquarters. The pharmacy expects to hire additional staff throughout the year to support its continued growth and expanded services.

As a member of the Guardian Pharmacy Services family, Guardian Pharmacy of South Carolina benefits 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.

Founded in 2004, Guardian Pharmacy Services has expanded from a single location to more than 50 pharmacies serving approximately 7,000 LTC facilities across the U.S. This growth has been fueled by a balanced strategy of organic expansion, greenfield startups, and acquisitions, supporting the company's success in a rapidly evolving market.
