Exhibit 99.1

Dear Team:

I am excited to announce that a definitive agreement has been executed with Marvell for Marvell to acquire Inphi. Inphi + Marvell will create an infrastructure semiconductor and optical powerhouse that will accelerate our growth and leadership in cloud and 5G. It is fitting that this year we are also celebrating our 10th anniversary as a public company and the 20th anniversary of our founding. The combined company will be led by Matt Murphy, CEO; Jean Hu, CFO; and key members of our joint management teams, including Loi Nguyen, our founder. I will be joining the Marvell Board of Directors after the transaction closes.

Inphi is doing very well on our own. In fact, we just announced record Q3 Non-GAAP revenue of $180.7 million, and record Non-GAAP operating profit of $53.3 million, or 29.5% of revenue. Our Q3 revenue grew 92% year over year, driven by strength in both our cloud and telecom markets. Out of that, the organic portion of our business grew 57% year over year in Q3. And we have guided to a revenue of $187 million at the midpoint for Q4, 2020. We anticipate being able to replace the lost revenue from Huawei in 2021, by continued strong ramps from cloud customers inside and between data centers, and telecom customers in long-haul and metro. Our PAM platform solutions for inside the data centers continue to command very high market share, and we continue to execute flawlessly ahead of the competition. Our ZR solutions are getting ready to transition and ramp from 100G to 400G in 2021. And our coherent solutions for long-haul and metro continue to take share from both competitors and captive ASIC solutions alike. As you all know we just shared with all of you our most recent Annual Strategic Plan (ASP) at recent town halls. It shows our plan to continue leadership in electro-optics for the interconnected world for years to come. This would result in Inphi being poised to continue to outperform the market in terms of addressable market expansion and revenue growth.

So why are we selling the company? Well, we’re not selling. We are merging with another strong growth company, with a proven management team, all of whom share our vision to accelerate the transition to the digital world. Marvell, under Matt Murphy’s leadership, has also transformed itself into a 5G juggernaut, and significantly increased their market share and market capitalization. They have transformed their business to focus on 5G, cloud, and automotive; markets very synergistic with Inphi. Our dream of making electro-optics solutions the standard for moving data around the world will be central to their vision to move, store, process and secure the world’s data faster and more reliably than any other company. Through this merger, Inphi as part of Marvell, will gain the scale needed to continue to invest, innovate, execute and deliver the best solutions to our cloud and telecom customers. While Marvell and Inphi have clearly differentiated product lines, they are complementary. The nature of this merger will enable our team to do well at Marvell, and to continue to pursue our dream of market leadership. Together, we address a combined $23 billion market growing at 12% CAGR. Together, we are stronger and plan to continue to generate strong shareholder returns in the future.

Exhibit 99.1

When I joined Inphi almost 9 years ago, Loi introduced me as the CEO who will be in charge of creating a mission for Inphi 2.0. Well, I am happy to report that this mission has been accomplished, in large part because of all the correct strategic decisions, hard work, and great accomplishments of our outstanding Inphi team. Today, I am pleased to announce, Inphi 3.0, the start of the new era under the Marvell brand and the leadership of Matt Murphy and our combined team once the deal has closed. We will remain separate companies until the transaction closes, but will start planning for integration right away. The next steps for both Inphi and Marvell will be to seek approvals from both of our shareholder bases. In parallel, we will immediately apply for regulatory approvals. In the meantime, and starting right away, let’s not take our eyes off the ball. We need to continue to execute. We need to continue to operate our company at our customary high levels of innovation, execution and customer satisfaction. We are still an independent company until the deal closes, and that may take anywhere from 6 to 16 months. There are also no assurances that the deal will close as planned. So please do not let up. It is essential that we continue to do what is best for employees, customers, partners and shareholders. We need to continue to create the world’s best solutions, deliver on high quality A0 products that will fulfill our customers’ requirements, support our customers going to production, and generate outstanding financial results.

With that, once again I thank each and every member of our phenomenal Inphi team for what you have accomplished over the past 20 years. Each and every one of you is an outstanding individual. Collectively we form an outstanding team. Keep up the good work!

Starting today we will be communicating with you to answer all the questions you may have. As usual, if you have any questions or comments, please feel free to email me, drop by my office (yes wearing a mask), or schedule time for a walk through my assistant, Molly Barber.

With deep thanks and gratitude to all of you,

Ford
