FAQ

General

Q. What is being announced today?

A. Rovi Corporation and Sonic Solutions today announced that the two companies have signed a definitive agreement for Rovi to acquire Sonic in a stock and cash transaction.

Q. Who is Sonic?

A. Sonic is a provider of digital video processing, playback and distribution technologies. Sonic has licensed its leading cloud-based digital media delivery infrastructure known as RoxioNow, to major retailers, movie studios and CE manufacturers. RoxioNow incorporates a catalog of over 10,000 movies and TV programs that are accessible through personal computers and over 8,000 connected CE devices. Sonic’s DivX offering is distributed in over 350 million CE devices. The DivX player software is downloaded over 100 million times per year and 500 million times cumulatively, and the DivX player software had over 2.5 billion launches since 2009. Sonic’s Roxio consumer products ship on over 90 million PCs and mobile devices each year.

More information on Sonic Solution’s portfolio:

• RoxioNow – the RoxioNow service, formerly known as CinemaNow, is a white label cloud based video distribution service. RoxioNow is well known to Rovi as we have done extensive integration with several of Sonic’s customers, such as Blockbuster and Best Buy (who now own the brand name CinemaNow). We are excited about the prospects of closer integration with TotalGuide, Rovi Metadata, search, recommendations and the other services in the Rovi Media Cloud.

• DivX – is comprised of core solutions including codecs, DRM, media players and device certification services targeting CE manufacturers. We share many customers as their customers are large CE manufacturers and we envision an expanded value proposition for these customers as we integrate the companies.

• Professional Technology – provides encoding solutions to companies that create professional video, such as Hollywood studios and even hardware manufacturers who capture video. Rovi has in the past integrated our RipGuard solution with one of the Sonic professional products. A brand many may know from this division is MainConcept, which is a widely used encoder.

• Roxio – is a leading media management suite of software well known in the consumer market. Roxio branded products are sold in retail, online and pre-loaded on PCs from major OEMs such as Dell and HP. This is a successful business that we anticipate will have relevance to our personal media manager among other ties to Rovi solutions

Q. Why has Rovi decided to purchase Sonic Solutions?

A. The acquisition of Sonic is consistent with Rovi’s strategic vision and focus on providing digital entertainment solutions. The acquisition will enable Rovi to broaden its solutions to content owners, device makers, retailers and operators. Sonic’s broad offerings coupled with Rovi’s guide software and metadata is expected to enhance Rovi’s ability to offer an end to end digital entertainment solution, enabling customers and consumers to create, discover, manage, distribute, and enjoy entertainment content.

Q. How is the acquisition of Sonic Solutions structured?

A. The two companies have signed a definitive agreement for Rovi to acquire Sonic in a stock and cash transaction. The enterprise value of the transaction is approximately $720 million and the per share value of Sonic common stock at signing of the agreement is $14.17, a 38% premium to Sonic’s 30 day average per share price. The acquisition is structured as an exchange offer for all of the outstanding shares of Sonic common stock followed by a merger.

Q. What is the price of the acquisition?

A. Under the terms of the agreement, which has been approved by both Boards of Directors, Sonic shareholders may elect to receive either $14.00 or 0.2489 shares of Rovi common stock for each share tendered and accepted in the exchange offer, subject to proration and adjustment pursuant to the definitive agreement. Cash consideration paid in the exchange offer will equal 55 percent of the aggregate value of consideration paid in the exchange offer and stock consideration issued in the exchange offer will equal 45 percent of the consideration, with shares of Rovi common stock being valued at $56.24 (the average closing price of Rovi common stock over the 20 trading days ending immediately prior to the date of the agreement) for purposes of such calculation. Upon consummation of the exchange offer, Rovi intends to complete a merger in order to acquire all the shares of Sonic common stock that remain outstanding after the completion of the exchange offer. If the initial exchange offer and related actions permitted by the agreement do not result in Rovi owning at least 90 percent of the outstanding shares of Sonic common stock, the consideration paid to Sonic shareholders in the merger may consist entirely of Rovi common stock at an exchange ratio of 0.2489 shares of Rovi common stock. Upon completion of the merger, Sonic Solutions will become a wholly-owned subsidiary of Rovi.

Q. When do you expect the exchange offer to close?

A. The exchange offer is expected to close during the first quarter of 2011 and is subject to regulatory approvals and customary closing conditions.

Q. Will there be layoffs as a result of the acquisition?

A. We are analyzing both organizations and evaluating the ongoing needs. Nothing will be known until after closing.

Q. What will happen to the Sonic Management team?

Q. When do you expect to integrate the Sonic technology?

A. We will develop a plan to integrate the technologies over time. We expect that integration work would begin upon the close of the second-step merger and that it will take an extended period of time to accomplish all that is envisioned.

Q. Do you anticipate any issues in obtaining approvals for this acquisition?

A. The exchange offer is subject to customary closing conditions and regulations.

Q. Will Rovi keep the Sonic brands?

A. Sonic has several strong consumer brands that are valuable to the combined company. During the integration process we will analyze the brands and what role each will play in the combined organization.

Q. Will RoxioNow and DivX be integrated with TotalGuide?

A. RoxioNow was integrated into TotalGuide as part of a separate commercial customer relationship with Blockbuster. As part of a separate customer relationship with Best Buy, work is already underway to integrate with Best Buy’s store powered by RoxioNow. As part of integration planning we will be considering what role DivX solutions will play with TotalGuide.

Q. There were plans for integration between Sonic and DivX, what happens to those plans?

A. Rovi and Sonic will operate as separate companies until the close of the transaction. Upon the close of the second-step merger, decisions regarding the DivX/Sonic integration plan will be communicated. It is expected that there may be some impact on the DivX/Sonic integration plans, but we cannot be specific at this time.

Q. How does today’s news benefit Rovi’s customers or partners?

A. As a combined company, Rovi and Sonic will be able power the next wave of digital entertainment offerings with content discovery, delivery, and enhanced interactivity capabilities that support advertising and drive consumer engagement. Backed by detailed metadata and tested retail components, the companies’ customers will benefit from synergistic technologies that allow consumers to create, find, access, manage, enjoy and experience digital media from the broadest range of digital devices.

Q. Will the integration impact Sonic’s relationship with Best Buy?

A. Rovi is excited about how the company can continue to work with Best Buy. We do not anticipate significant changes to our and Sonic’s customer relationships and hope to expand upon the services that we provide to them.
