Exhibit 99.3

Client Talking Points

· As you saw, we recently announced some exciting news about PharMerica.

· PharMerica has entered into an agreement to be acquired by a newly formed company controlled by KKR, with Walgreens Boots Alliance as a minority investor.

· Once the transaction is complete, PharMerica will become a private company.

· Today’s announcement is great news for our clients, customers and patients. We have formed a great partnership. KKR is one of the most successful private equity firms in the world, and Walgreens is a world-class pharmacy services organization.

· This partnership will significantly enhance our ability to develop and rapidly scale new products and services specifically directed towards addressing the changing needs of senior care.

· Over the past several years we have focused our efforts on providing world-class pharmaceutical services to our clients and customers and developing innovative solutions to address the changing needs of senior care. For example, we introduced products such as TransitionRx™ and DischargeRx™ to reduce the risk of re-hospitalization. We launched ValueMed™ a unique medication management service for the Assisted Living Facilities and residents. Partnering with Walgreens, the largest provider in the U.S. with a reputation for high quality, will significantly enhance our ability to roll out and scale our products and services.

· Serving you, our client (customer), remains our top priority, and we are committed to continuing to deliver the exceptional services you have come to expect. The ownership structure of PharMerica will change, but our leadership, your normal contacts at the Company, and our commitment to excellence will remain the same.

· We expect the transaction to close by early 2018, but until the transaction closes, it is business as usual at PharMerica.

· Thank you for your continued support and we will keep you updated on any important developments. Please feel free to reach out with any questions.
