The Future of Animal Health & Wellness

Platinum Performance® and Zoetis Inc. To Join Forces to Redefine Nutrition and Wellness

Expand Copy

July 22, 2019

Today we are announcing that Platinum Performance is joining forces with Zoetis Inc., the largest animal health company in the world. This will allow us to increase our research and development activities and expand our leadership in nutrition-focused animal health globally.

Perhaps most excitingly, this relationship connects the world-class laboratory diagnostics capabilities of Zoetis with Platinum Performance. This connection will enable us to further develop our vision for the field of scientific wellness, a new frontier in veterinary medicine and animal health, resulting in improved levels of disease and injury prediction, prevention, and more targeted and timely treatment.

After the acquisition is completed, which is expected to be later this summer, we will continue to operate as a distinct business and brand. We will continue to support you from our Buellton, CA, headquarters and your experience with our team will be unchanged. My team and I will lead Platinum Performance the same way we have for over 20 years, into this exciting new frontier in how we care for our beloved horses and pets.

We greatly appreciate your support in the growth and evolution of Platinum Performance and we look forward to continuing to serve you.
