Excerpt from Internal Communication to Employees, distributed September 1, 2016

Q: Is this acquisition a good thing? What are the goals of the integration?

A: Yes! We believe that the combination of Lionsgate and Starz will create a global content powerhouse that gives the combined entity greater scale for attracting world-class talent, creating platform-defining content and distributing it with an incredible array of options. The transaction unites two companies with strong brands and complementary assets and positions us to be an even stronger, more diversified, content-driven company.

When the transaction is complete, the combined entity will encompass: a world-class independent television business including nearly 90 series on more than 40 different networks; a feature film business that has generated an average of nearly $2 billion at the global box office each of the past four years; operation of or investment in 30 channel platforms around the world, including the flagship STARZ platform reaching more than 24 million U.S. subscribers, the STARZ ENCORE network with nearly 32 million subscribers and four OTT services; a 16,000-title film and television library; and a growing presence in location-based entertainment and video games driven by the company’s deep portfolio of brands and franchises.

Q: How long will the integration planning phase last? When will planning be complete?

A: We expect the transaction to close before year-end, meaning all planning for the combination should be completed by then as well. During this initial planning phase, the integration team members will develop function-specific plans and recommendations for integrating and aligning policies, procedures and technologies. Full integration in some areas may extend into 2017.

Q: How long will it take to move the organization to one company? When will changes start taking place?

A: Some quick process or system consolidations may be implemented in the near term after the transaction closes. Broader initiatives may take up to 18 months to implement.

Q: Who is involved in the integration?

A: We have selected colleagues from both Lionsgate and Starz to serve on the integration team. As we progress in our planning, we will evaluate the need to include additional colleagues in our planning efforts.

Q: Are we engaging any external help with integration planning?

A: Deloitte Consulting has been engaged to assist us with integration planning. They will be on-site at Lionsgate for the next several weeks and will assist our integration teams with development of integration plans and recommendations.

Q: What happens next?

A: Until the transaction is complete, Starz and Lionsgate will remain separate companies, and it will be business as usual in our day-to-day responsibilities of delivering great entertainment to our customers. Over the longer term, the combination of Lionsgate and Starz will create exciting new opportunities that we expect to make our two companies even stronger and more dynamic.

Q: When will we hear more specifics about the changes that are going to happen?

A: The Communications and Human Resources teams will update employees on a regular basis and provide information as it becomes available.

Q: What can I communicate externally?

We’re in the process of establishing procedures for both internal and external integration-related communications, and it’s important that we speak with a single unified voice.

Q: What is leadership’s philosophy on communications?

We beleive that our similar entrepreneurial cultures and shared vision of the future will make this alliance an incredible fit that creates tremendous value for our shareholders, great content for our audiences and limitless opportunities for our newly-combined company.
