Email from Scott McGregor to Broadcom Employees

Broadcom Colleagues,

Today marks the next chapter in Broadcom’s incredible history – a landmark transaction with Avago that creates the industry’s third largest semiconductor company. The combined company will be called Broadcom Ltd. You can read the press release here (insert link).

It has been an amazing journey. In the ten years that I have been CEO of Broadcom, we have successfully expanded our leading franchises for the wired and wireless end markets. We have grown our footprint in a range of markets including set-top boxes, broadband access platforms, connectivity for portable devices, switching for the enterprise, data center and service provider as we strived to realize our mission of Connecting everything. The company generated just over $2.5 billion in revenue in my first year as CEO, and we grew that to over $8 billion in 2015.

The journey is not over. Today’s news is exciting because it better prepares the combined company for the next step in the communications industry. The industry is changing and we believe that to deliver success for both our customers and our shareholders, significant size and scale are becoming increasingly important. The combination of Broadcom and Avago are better prepared for that next step.

We believe the transaction benefits all of Broadcom’s key stakeholders. Our customers will gain access to a greater breadth of technology. Our employees will benefit from opportunities as part of the third largest semiconductor company in the world. For our stockholders, the transaction provides both compelling up-front value as well as the opportunity to participate in the future upside of the combined business.

We are very proud as well that the entity that emerges from the combination of Broadcom and Avago will carry the Broadcom name. The new Broadcom will build on the strengths of both companies to emerge as a leader in both the communications markets as well as the broader semiconductor industry.

As I know you will have questions, I would like to invite you to a special live All Hands meeting and webcast today at 10 a.m. PT where Henry and I will discuss the significance of today’s news. If you are in Irvine, please join us in the Building 2 Cafe. Employees worldwide can log on for the All Hands webcast here [insert link]. Following the webcast an employee FAQ will be posted on the Intranet.

We expect the transaction to close in the first quarter of 2016, subject to regulatory approvals and customary closing conditions. Please remember that we remain subject to confidentiality obligations with respect to the pending transaction and our comments will be limited to information already publicly disclosed. We will operate as separate companies and it will be business as usual until close.

Thank you for your dedication and enormous contributions to Broadcom and please look out for continued communication.

Scott
