Cavium–Marvell – Integration Update – February 2, 2018

Cavium and Marvell Employees:

Following through on our commitment to keep you informed on the integration’s progress, we are sending you bi-weekly updates, and will post answers to your most commonly asked questions.

LATEST NEWS

 

  Our federal antitrust review period, as mandated under the Hart-Scott-Rodino Act (HSR), is now over. As we announced in our January 29 press release, this moves us one step closer to our proposed merger. Up next are several other regulatory reviews and shareholder approvals.

 

  On January 17, the integration team’s functional leaders reported on their initial analyses, identifying key dependencies and upcoming decisions. After incorporating feedback, they will share their updated integration plans with the Steering Team in mid-February.

ANSWERS TO YOUR QUESTIONS

Thanks for your questions. Please know that we are committed to sharing information with you as soon as it becomes available. In the meantime, the following are some of the most common questions received:

When is the transaction expected to close?

We are on track to close in mid-calendar 2018. However, this deal is still subject to normal regulatory reviews, which move at their own pace. Our progress in these reviews, along with shareholder votes by both companies, will ultimately determine our closing date. As such, we do not have a specific date at this time.

Are we able to continue hiring for open positions, even with this deal pending?

In many cases, yes. However, certain restrictions may apply. Please check with your manager, recruiter or HR business partner.

Will we consolidate facilities at common locations?

Over time, yes. Our companies currently share many similar locations, and co-locating our employees will enable stronger teamwork and help lower our real estate costs. Our goal throughout facility consolidation will be to minimize disruption to business operations.

Will my company benefits change after the deal closes?

We are currently evaluating Cavium and Marvell benefits offered in each country and will align plans over time, after the deal closes. We will provide more information as soon as we know final decisions and timelines.

Can I communicate with my counterpart at the other company before the deal closes?

No. Until this deal has formally closed, we need to continue operating as two separate and independent companies. As such, all of your non-disclosure and intellectual property agreements still apply. If you have an urgent question or need, please contact your manager or – if necessary – your company’s integration leader.
