Subject Company: Qualcomm Incorporated

(Commission File No. 000-19528)

To All Broadcom Employees:

I am writing to provide an update regarding our proposal to acquire Qualcomm. This morning we notified Qualcomm of our intention to nominate 11 independent, highly qualified nominees to the Qualcomm Board of Directors for election at Qualcomm’s Annual Meeting of Stockholders scheduled for March 6, 2018.

Since announcing our proposal, we have heard from many Qualcomm stockholders who have expressed a desire for Qualcomm to engage in discussions with us in order to realize the benefits of our compelling proposal. We have repeatedly attempted to have discussions with Qualcomm, and despite these attempts and stockholder and customer support for the transaction, Qualcomm has refused to engage with us.

By announcing our intention to nominate a slate of independent director nominees, we are providing Qualcomm stockholders with an opportunity to voice their disappointment with Qualcomm’s refusal to engage in discussions with us.

A combination of Broadcom and Qualcomm will create a leading global communications company that is well positioned to deliver more advanced semiconductor solutions for our global customers and create meaningful value for stockholders of both companies. We continue to believe that employees of both Broadcom and Qualcomm will benefit as part of a larger company, and we are committed to doing what it takes to making this transaction a reality.

Importantly, today’s announcement has no impact on our day-to-day operations – it is business as usual at Broadcom. If you receive inquiries from outside parties, please forward them to Ashish Saran at 408-433-4557 or ashish.saran@broadcom.com.

It is important you stay focused on the opportunities in front of us as we start fiscal 2018. You should be proud of all that we’ve accomplished during the past fiscal year, and I thank you for your commitment to the company.

Regards,

Hock Tan
