Subject: SiriusXM to Acquire Pandora

Attach: Employee FAQs

Team,

We have big news this morning. We just announced (https://www.streetaccount.com/pressrelease.aspx?ticker=P&intraday_id=2430189) that we’ve entered into an agreement to be acquired by SiriusXM, in an all-stock transaction valued at approximately $3.5 billion.

I recognize this is a lot to process as you wake up. So let me jump right to a few key points about this news and why I’m personally excited for the opportunity it presents for Pandora.

First, I’m sure many of you will have questions about what this means for you and your teams. Until the deal closes – likely in Q1 of 2019 – it’s business as usual here at Pandora. We’ll continue to operate as two independent companies until the close of the transaction. After the closing, our company will operate as a wholly-owned subsidiary of SiriusXM. And the powerful Pandora brand you’ve all worked so hard to build will remain intact. There will be no immediate changes to our product offerings, beyond what we already have planned. So just as we do every day, we need to stay focused on our priorities and on serving our listeners and partners.

All of you should be very proud of what this acquisition represents for us as a team and as a company: a chance to accelerate our efforts and enhance the resources we have to grow our business and extend our leadership in digital audio. Your hard work and dedication created this opportunity. We’ve made strong progress this year on our priorities to grow our audience and improve our ad capabilities, marketing and partnerships. SiriusXM clearly recognizes the value of the amazing platform and momentum we’ve built. And so in this context, it’s actually no surprise that they want to combine forces to further amplify the success you’ve created and find new ways to succeed jointly.

Together with SiriusXM we’ll create the world’s largest audio entertainment company. SiriusXM’s products and Pandora’s products are very complementary with very little overlap. They are best in class in the curated subscription audio business and we are best in class in the personalized audio streaming business and the digital ad business. Given our strategic priorities and our recent conversations about expanding non-music content, increasing in-car engagement and enhancing brand awareness, the benefits of the combined company are easy to see. In short, we’ll have even more support to innovate, collaborate and grow together.

Finally, we know the SiriusXM team well and I believe we’ll be able to work very well alongside them. SiriusXM made a significant investment in Pandora 15 months ago. For the past year, Jim Meyer, Greg Maffei and David Frear have sat on our board and have been very supportive of our strategy. Importantly, the combined company will need both the SiriusXM and Pandora teams to continue running their businesses after we complete the transaction.

We’re going to set up an integration team, and we’ll keep you informed. We’ll also hold a company meeting today at 9am PT / 12pm ET to discuss and take your questions. I’ve also attached an FAQ to address some questions that may be on the top of your mind, including the specifics of the transaction.

Our recently revised Purpose called on us to change the way people listen. I believe as the world’s largest audio entertainment company, we’ll have great opportunity to do just that.

Roger

Senior Leadership Team,

As you saw in my email, we have big and exciting news. Thank you all in advance for the important role you’ll play today and in the coming weeks communicating with your teams and keeping our employees focused.

From an internal perspective:

Communications Materials

Attached is the same FAQs document from my all-employee email earlier. It’s important to emphasize that this announcement should have no immediate impact on our day-to-day operations. In addition, the first question covers a high-level overview of some of the mutual benefits we expect to realize through the proposed combination, which I hope you’ll feel comfortable talking through with your teams.

As you familiarize yourself with the communications materials, please also keep in mind:

You are likely to receive many questions that you will not be able to answer directly. It’s always okay to acknowledge that we don’t yet have all of the answers. If helpful, you can always respond with something like:

“That’s a great question. It is early in the process, and I do not have all the answers today. There are still many details to be worked out and I will get back to you on that.”

We’re committed to continuing to get you more information as it becomes available. If you have questions you can’t answer, please reach out to Sam Morgan who can help make sure we add it to our list.

Thank you and talk to you soon.

Roger

Strategic Rationale Combination creates the world’s largest audio entertainment company with more than $7B in revenue, a $41B enterprise value, low leverage and strong cash flow Builds on SiriusXM’s position as the leader in subscription radio and critically-acclaimed curation with the addition of the largest U.S. audio streaming platform Enables SiriusXM to significantly expand its presence beyond the vehicle into the complementary in-home & mobile entertainment area Diversifies revenue streams with the U.S.’s largest ad-supported digital audio offering and enables continued expansion in North America Creates a strong promotional platform for emerging and established artists to reach and grow their fan base

Growth Opportunities Leveraging SiriusXM’s exclusive content and programming with Pandora’s free ad-supported and subscription tiers to create unique audio packages Utilizing SiriusXM’s extensive automotive relationships to drive Pandora’s in-car distribution Cross-promotion opportunities between SiriusXM’s base of 36M+subscribers across North America & 23M+annual trial listeners and Pandora’s approximately 70M+active listeners Combining investments in content & technology and expanded monetization capabilities across both ad-supported and subscription services in and out of the vehicle 360L deployments combined with Pandora’s digital & ad capabilities to drive increased share of in-car ear & wallet vs other platforms

Transaction Overview Transaction Consideration Pandora stockholders to receive 100% stock consideration at a fixed exchange ratio of 1.44shares of SiriusXM for each share of Pandora Equivalent to $10.14per share, representing a 13.8% premium based on the 30-day VWAP of both companies’ shares Transaction valued at approximately $3.5 billion, including assumption of debt Pandora stockholders to own 8.6%of the pro forma company on a fully diluted basis Expected Closing Expected to close in Q1 2019 subject to Pandora stockholders approval, antitrust approvals and customary closing conditions

Pandora Blog Post, dated as of September 24, 2018

You may have noticed that big things (https://finance.yahoo.com/news/siriusxm-acquire-pandora-creating-worlds-110000794.html) are happening at Pandora.

Earlier today, we announced that we’ve entered into an agreement to be acquired by SiriusXM, in an all-stock transaction, valued at approximately $3.5 billion.

Here’s what this means for our listeners, and why we’re excited:

First, and most importantly, the Pandora that you know and love today will continue to deliver you the music that you want to hear. Whether you’re a user of our ad-supported service, or enjoy either Pandora Plus or Pandora Premium, our products and their pricing aren’t changing as a result of this announcement.

And, the Pandora brand – instantly recognizable to our tens of millions of monthly users – is here to stay.

Second, once the transaction has closed, the combined company will be the largest audio entertainment business in the world. That kind of scale means that we’ll be even better able to provide our users an exceptional audio experience – no matter where they are, how they’re listening and what they want to listen to.

Over time we’ll work together with SiriusXM to reimagine the future of audio – finding new ways to curate and launch unique product and content packages and deliver a seamless, engaging and always entertaining experience to the very people who made Pandora possible in the first place: all of you.

Stay tuned!
