TiVo Customer Letter

April 29, 2016

[INSERT STANDARD GREETING],

Today, we begin a new chapter in TiVo’s history. We are very pleased to share that we are combining with Rovi to create a leading provider of discovery solutions, recommendations, advertising and analytics. We value our relationship, and I wanted to make you aware of this important news in a timely manner.

We are confident this transaction will bring exciting opportunities for our customers. Combined, we will have significant scale, representing over 500 service providers across 70 countries, and will be able to leverage significant R&D resources for our customers.

This transaction provides us with two strong foundations from which to grow in the rapidly evolving entertainment landscape. Operating together under the TiVo name, we will have the opportunity to create solutions for MVPDs that integrate and bundle software, cloud services, metadata, advertising, and analytics. Just as how our Digitalsmiths acquisition augmented the TiVo product line in discovery, we expect the combination with Rovi to yield additional product benefits. We believe Rovi’s market leadership in metadata and analytics, combined with TiVo’s expertise in user experience and MSO integration, will deliver significant and sustained innovation to our customers going forward.

We have long discussed the importance of becoming a large scale provider of software and services in the pay television marketplace. Scale helps us invest in even more innovation and allows us to be more flexible in addressing the unique needs of each of our customers. Scale enables us to expand our product portfolio and to provide more comprehensive end-to-end solutions that help our customers achieve efficiencies in their own operations. Together, Rovi and TiVo spend ~$200 million annually in R&D, making us one of the biggest suppliers to the industry.

Our relationship with you, our customers, is our top priority and we will continue to provide you with the same best-in-class products and support that you have come to expect. Looking ahead, the transaction is expected to close in Q3 2016. I want to assure you that our customers will remain our top priority and you will not see any change in our commitment to you or our levels of quality and service during this time. Until the transaction has closed and all necessary approvals have been granted, TiVo and Rovi will continue to operate independently. We will honor all contracts in place before the transaction, and we do not expect this transaction to impact TiVo’s day-to-day business operations or engagement with you.

We have attached a copy of the press release and will keep you updated throughout the integration process. As always, if you have any questions about this announcement, please do not hesitate to reach out.

We are excited about the tremendous benefits that this transaction offers and the continued growth of our company and yours. We recognize that you have played a critical role in our success to date and we look forward to being an even stronger business partner for you going forward.

Thank you for your continued support of TiVo.

Sincerely,

[NAME]
