Zoetis Inc.

To reduce costs and be environmentally responsible, we have adopted an SEC-approved procedure called “householding.” Under this procedure, we may deliver a single copy of the notice of internet availability of proxy materials and, if applicable, this proxy statement and the Annual Report, to multiple shareholders who share the same address unless we have received contrary instructions from an impacted shareholder at that address. Shareholders who participate in householding will continue to receive separate proxy cards. Upon written or oral request, we will promptly deliver a separate copy of the notice of internet availability of proxy materials and, if applicable, this proxy statement and the Annual Report, to any shareholder at a shared address to which the Company delivered a single copy of any of these documents. If you are a registered shareholder and would like to enroll in this service or receive individual copies of this year’s and/or future proxy materials, please contact our Corporate Secretary by mail at Zoetis Inc., 10 Sylvan Way, Parsippany, NJ 07054. If you hold shares in street name or in a Zoetis benefit plan, you may contact your brokerage firm, bank, broker-dealer, benefit plan provider or other similar organization to request information about householding.
