Subject: Follow up on last Monday’s announcement

Following last Monday’s announcement of EMC and Dell coming together, I’ve been able to meet with thousands of our colleagues to hear their thoughts and take their questions. I’ve also been speaking with customers and partners. By the end of this week, I will have visited 14 locations across the U.S. and EMEA, hosting more than 25 all hands and leadership team meetings. In the coming weeks we will cover APJ and Latin America.

This intensive outreach is giving me a first-hand appreciation of the emotions of our employees and customers and partners. Clearly, there is a lot of information to digest, and many questions may not have answers until we move closer to the actual merger date. But the undercurrent of optimism and excitement for what this combination means for our collective future comes through loud and clear as people gain a much clearer picture of our future. Internally, the EMC DNA is kicking in, and the employees I’m meeting with are energized to roll up their sleeves and make it happen.

Between last Monday’s signing and the deal close, which we expect to occur in mid-2016, it is important for EMC and Dell continue to operate as separate businesses. We are, however, permitted to begin integration planning together. As Joe notes below, he has asked Howard Elias to lead the integration effort on behalf of the Federation. In addition, I have asked Howard to also serve as our designated leader for the EMC II integration, which is where most of the larger effort will be focused. Throughout this exercise, Howard will also continue in his role leading Global Enterprise Services, as a member of our EMC II senior leadership team.

Integration planning will start in earnest within 30-45 days, and Howard will soon begin developing plans and will determine additional integration team members as time goes on. In the meantime, please ensure that any and all discussions with Dell are coordinated with him. In the meantime, I cannot stress strongly enough that we need to focus on our business: serving our customers and executing and delivering on our commitments for this quarter (including our business transformation initiatives), further developing our plans for 2016, and communicating aggressively with our teams throughout all of this. In times of significant changes, there is no such thing as over communicating, so keep your teams informed and stay close to your people! For the latest information on what we can say about EMC – Dell please visit Inside EMC.

I will have more to say to our larger employee base during our all hands Quarterly Review meeting on Wednesday, which will be a live stream multicast beginning at 3pm ET.

Subject: Customers, Integration & The Federation—My Thoughts On Week 1

I would like to share what I’ve been hearing from customers since our big announcement last Monday:

Customers are responding positively in the conversations I’m having. They see the logic of the EMC/Dell combination and are excited about the possibilities and what this means for their future… to have a strategic partner with more heft and relevance to their digital and IT transformations as they plan their strategies around software-defined data center, hybrid cloud, converged infrastructure, mobile and security. They understand how moving to a privately-controlled model will allow us to incubate young businesses and invest more for the long haul without the pressure of managing for quarter-end. Customers do ask about the debt expense, but remember that over the last three years, EMC alone has averaged approximately $3.5 billion annually on share repurchases and dividends. Furthermore, the collective cash flows of the combined company will allow it to keep investing heavily in R&D and innovation, GTM and resources to provide first-class services and support to our customers. Customers also like the fact that our future breadth and scale means we will no longer be the “smallest of the big” tech companies. Upon closing, we will be a clear leader for enterprise technology, with significantly more product and technology revenues than our nearest competitor. That will ensure us a place on every consideration list for transformative IT projects. Additionally, our VCE customers are very happy to hear about our joint commitment with Cisco to VBlocks for the long haul!

Now that we have entered into a definitive merger agreement with Dell, we need to begin our planning for the post announcement integration activities while we continue to run the business. It is important that we have a coordinated approach across our companies and business units and to help assure this I have asked Howard Elias to become the Federation integration leader. Howard will report directly to me in this new role and become the primary interface with Dell on integration matters. We will form a steering committee along with a framework to help coordinate all the integration activities, and I ask you to assign someone from your team to join this important effort.

Finally, to clarify what we announced last Monday: until the transaction closes, we must/will continue to operate our family of companies as we always have: with a laser focus on the success of our customers and growth. In doing so we will continue to refer to our combination of businesses as “The (EMC²) Federation” and as such we will continue to execute on our Federation solutions, technology collaborations related to Software-Defined Storage, CI, and Cloud Native Apps, and GTM plans/initiative under Jeff Casale. Both Michael Dell and Egon Durban from Silver Lake have said they see great value in our Federation model… it gives us focus of mission, an ability to attract and retain world class talent and collectively gives our customers a compelling vision for the future, without lock-in.

Thank you for your support and cooperation.

Best, Joe

Team,

Please find below a message I received from Joe Tucci with an update following the Dell announcement on Monday of last week. I am pleased but not surprised to hear that the news has been received positively by our customers. He reports that they see the value and logic of the combination of our businesses and are excited about what this means for their future.

Take a moment to read his message as it includes important information regarding the go forward strategy for the Federation and the integration with Dell.
