What are the terms and structure for the transaction?

 

•

Under the terms of the definitive agreement, Marvell will pay Inphi’s stockholders $66 per share in cash and 2.323 Marvell common shares for each Inphi share. Marvell intends to finance the transaction with cash on hand and new borrowings.

 

•

In conjunction with the transaction, Marvell intends to reorganize so that the combined company will be a Delaware incorporated corporation (Marvell is currently a Bermuda company and Inphi is a Delaware company).

When is the transaction expected to close?

 

•

The transaction is currently expected to close in the second half of calendar 2021, pending approval by Inphi’s and Marvell’s shareholders, as well as regulatory approval and other customary closing conditions.

Is there a chance the transaction will not close?

 

•

The agreement has already been approved by the boards of directors of both companies, and the leadership teams at Marvell and Inphi are committed to closing the transaction.

 

•

Transactions of this nature require regulatory and shareholder approval, but given the complementary product sets, we believe the various parties will find the mutual benefits of this combination compelling.

Until the transaction closes, will Marvell and Inphi operate as one company or two?

 

•

Until the deal closes, we are required to operate as two separate and independent companies.

Integration

The press release says the transaction is expected to generate $125 million in synergies within 18 months post-closing. What does that mean?

 

•

Combining two companies creates opportunities to save from a larger purchasing base with suppliers on cost of goods sold.

 

•

There are opportunities to reduce common operating expenses needed to run a separate public company.

 

•

We expect to consolidate real estate where practical. For example, Inphi’s headquarters is very near Marvell’s Santa Clara offices.

 

•

There will also be savings as we rationalize general administration spending to run the combined business.

What impact will the planned combination have on our respective product roadmaps?

 

•

Marvell and Inphi will both continue with their independent product roadmaps and development plans through the close of the transaction.

 

•

The current portfolios are very complementary. Over the coming months, Inphi and Marvell will review the respective companies’ product roadmaps and forward-looking plans.

When will we know what groups or functional areas will be impacted?

 

•

It will take several months to review and assess the organization structure and determine the best way to integrate the two companies.

 

•

Integration planning decisions will be communicated once known, after the transaction closes.

 

•

While there will inevitably be changes in areas where there may be overlap in responsibilities of certain roles, we expect most employees will continue in their current roles.

 

•

There will also be opportunities for employees to apply for new positions in the combined company.

Where are Marvell’s facilities?

 

•

Marvell’s largest campus is located in Santa Clara, CA, several blocks from the former Inphi building on Bunker Hill Ln. You can view Marvell’s global locations on their web site: https://www.marvell.com/company/offices.html

Will we consolidate facilities at common locations?

 

•

Our companies share some common locations, and during integration planning we will assess opportunities to combine nearby teams into a single location where practical.

 

•

We believe co-locating our complementary teams will foster greater teamwork and collaboration.

Will we close any sites altogether?

 

•

We will assess and determine our site strategy during the integration planning process.

When can we start to work together on product development or other activities?

 

•

Until the transaction closes, we need to continue operating as two separate and independent companies.

•

With this in mind, it’s important that you do not contact any counterparts at the other company without prior approval from the corporate development team until the transaction is done.

•

It is too early to speculate on any job impact. During integration planning, we will analyze the right structure for the combined organization.

Between now and the close, you will be subject to the trading window policy at your current employer. As a reminder, you may not trade in stock of either Marvell or Inphi if you are in possession of material non-public information about such company.

What will happen to Inphi stock options and/or RSUs upon the closing of the transaction?

 

•

A separate FAQ will be provided to Inphi employees as we get closer to the closing, outlining in detail the equity treatment as a result of the closing of the transaction. However, below is a high-level summary of what you can expect.

Stock Options

 

•

In-the-money options held by continuing employees as of the closing are assumed and converted into options to purchase Marvell common shares using a conversion ratio designed to preserve the aggregate “spread” of the related Inphi option determined at closing.

 

•

Each vested in the money option held by an individual who is not a continuing employee is cancelled in exchange for a payment equal to the difference between the price per share payable for Inphi common stock in the transaction and the per share exercise price of the Inphi option.

•

Underwater options as well as unvested options held by individuals who are not continuing employment post-close are cancelled and the holder will not receive any cash payment.

Restricted Stock Units (RSUs)

 

•

Shares that are held by employees at the time of the closing that were issued to them when their Inphi RSUs vested or purchased under the Inphi ESPP program will be treated like all other Inphi shares and converted into the right to receive the merger consideration which is a combination of cash and Marvell stock.

 

•

Unvested Inphi service-based RSUs held by continuing employees are converted into unvested Marvell RSUs based on a conversion ratio reflecting the purchase price. These service-based Marvell RSUs will be subject to the same terms and conditions, including the vesting terms, as the unvested Inphi RSUs that are being converted.

 

•

Unvested RSUs held by individuals who are not continuing employment post-close are cancelled. There is no conversion or cash payment.

ESPP

 

•

The final offering period for the Inphi ESPP program will be determined based on the anticipated timing of the closing. The program will terminate at least three business days prior to the closing of the transaction, or at the end of the 6-month offering period, (whichever is sooner). At that time, shares of Inphi common stock will be purchased, then canceled and converted into the right to receive the same consideration payable for Inphi common stock in the transaction (stock and cash).

 

•

Former Inphi employees will be able to enroll in the Marvell ESPP plan at the next available offering period after the closing of the transaction.

What happens to Inphi employee benefits upon the closing of the transaction?

 

•

Inphi benefits plans will remain in place until transition dates are determined in each country, as applicable. Please see https://www.marvellbenefits.com/ for an overview of benefits offered to current U.S. Marvell employees. However, this site does not provide any information that is specific to Inphi employees or how benefits will transition.

Does Marvell offer a 401(k) plan in the U.S.? What happens to my Inphi 401(k) plan account?

 

•

Marvel’s 401(k) provider is Charles Schwab, and Inphi employees in the U.S. will be eligible to participate in Marvell’s 401(k) plan as soon as administratively possible after the close.

 

•

Inphi’s 401(k) plan will terminate upon the close of the transaction and Inphi employees will no longer be able to contribute to the Inphi 401(k) plan. Inphi employees may roll over a Inphi 401(k) plan account to the Marvell 401(k) Plan, or another qualified retirement account.

Does Marvell offer a 401(k) match?

 

•

Yes, Marvell will match up to a maximum of $5,000 per year.

How does Marvell’s culture compare to Inphi’s culture?

 

•

Our two companies are strategically aligned with highly complementary product portfolios, and very similar values founded upon engineering excellence, innovation and a passion for our customers’ success.
