For Immediate Release

HENRY SCHEIN AND VETS FIRST CHOICE ANNOUNCE NEW NAME OF THE PLANNED NEW COMPANY: COVETRUS

New Executive Leadership Team Announced For Covetrus To Advance the World of Veterinary Medicine

MELVILLE, N.Y., and PORTLAND, ME, December 20, 2018 – Henry Schein, Inc. (Nasdaq: HSIC) and Vets First Choice today announced that the new standalone public company that will result from the planned spin-off of the Henry Schein Animal Health business and the subsequent merger with Vets First Choice will be named Covetrus.

The transaction is expected to be completed in the first quarter of 2019.

The new company, Covetrus, will be a global, technology-enabled animal health business supporting the companion, equine and large-animal veterinary markets. Covetrus will combine leading practice management software, prescription management, multi-channel client engagement services, and supply chain infrastructure to promote connectivity between veterinarians and their clients.

Covetrus will employ more than 5,000 team members across approximately 25 countries, delivering integrated solutions to help veterinary practices to improve the economics and workflow of their businesses and enhance the client experience. The business will have approximately 100,000 customers across major geographic regions, including North America, Europe, Australasia and South America.

Covetrus reflects the company’s deep partnership with the veterinary community and its efforts to “Advance the World of Veterinary Medicine.” “Co-” highlights working together as partners, anchored by “vet” at the center of what the company will do, and “-us” reinforces the notion of a team of professionals who will serve as an extension of the veterinary practice.

“It was important to create a new brand and new name that demonstrates our long-term commitment for veterinary practice customers to always be at the center of our business. We are committed ‘To Advancing the World of Veterinary Medicine’ by empowering our customers with compelling new capabilities and services to drive new health and financial outcomes to ensure their continued success,” said Benjamin Shaw, Founder and CEO of Vets First Choice. “Covetrus reflects the excitement around our unique capabilities and differentiated value proposition that this combined entity will deliver to veterinary customers across the globe.”

The two companies also announced today the proposed executive leadership team of Covetrus.

As previously announced, Benjamin Shaw, will become CEO of the combined company and serve as a member of the Board of Directors. The executive leadership team of Covetrus will include:

“This is an impressive and talented leadership team, and we are honored to lead this soon-to-be new independent organization,” said Shaw. “This executive team will ensure strong continuity of leadership across all lines of business and geography and includes new talent to facilitate a smooth transition into an independent public company. Importantly, our team is committed to meeting and exceeding the expectations of our customers.”

Henry Schein Animal Health and Vets First Choice will continue to operate as two independent, separate organizations prior to the closing of the transaction.
