… Long-Term Strategy of Mellanox

Mellanox Technologies, Ltd. announced that its board of directors is mailing a letter to shareholders emphasizing the importance of the company’s extraordinary general meeting of shareholders and highlighting its long-term growth strategy and focus on operating margin improvement.

The full text of the letter follows:

March 12, 2018
Dear Fellow Shareholders,

On behalf of the Mellanox board of directors, we are writing to you today to emphasize that we believe calling an extraordinary general meeting of shareholders (EGM) is essential to protecting shareholder choice, to reiterate that continued successful execution of our long-term growth strategy is delivering value and to provide some clarity to certain perspectives in the marketplace.

EGM Proposals Reflect Our Board’s Commitment to Best-in-Class Governance
At Mellanox’s EGM in May 2018, shareholders will be asked to vote in favor of two best-in-class governance proposals, designed to enhance shareholder choice in a contested election by allowing shareholders to vote for the director candidates who they believe will best guide Mellanox’s strategy and success over the long term.

First, you will be asked to establish plurality voting in the event of a contested election. With a plurality voting standard, which has been adopted by the vast majority of U.S.-listed companies in the event of contested elections, the board would consist of the director nominees gaining the greatest number of votes and all of the directors who serve on the board would be elected directly by shareholders. Under our current majority voting structure, it would be possible for fewer than 11 director candidates to receive the necessary votes to get elected, leaving vacancies to be filled by those majority-elected directors rather than by you, our shareholders. Such an outcome becomes particularly likely in contested elections, where votes may be split among a larger number of nominees.

Second, you will be asked to vote in favor of the use of universal proxy cards, which would require any nominee to the board to consent to being named as a nominee in any proxy statement or proxy card used in connection with the general meeting at which directors will be elected. The adoption of universal proxy cards will provide for all nominees put forth by either the board or any shareholder of Mellanox to be listed together on one universal proxy card, enabling shareholders to elect any combination of director nominees they choose. Under our current rules, shareholders may only validly submit one proxy, meaning they cannot easily cast votes for nominees from both proxies as they could when voting in person.

EGM is an Essential Step to Protect Shareholder Choice and Interests
We strongly believe that the composition of the Mellanox board of directors should reflect the true intentions of our shareholders. We have carefully taken into consideration many different factors, including a detailed consideration of all relevant U.S. and Israeli legal requirements. We have scheduled the EGM as soon as practicable in order to ensure that all shareholders’ voices will be heard.

On January 17, 2018, without warning and despite what we believed to be constructive discussions, Starboard Value LP nominated a full slate of directors to the Mellanox board with the intention of replacing all of the current directors and taking control of the company. Thus, the decisions made at the company’s annual general meeting of shareholders (AGM) will truly affect the future of Mellanox. In light of this, the Mellanox board, in consultation with our independent financial and legal advisors, immediately conducted a comprehensive assessment on how to proceed in the best interests of its shareholders. This review made it clear that updating Mellanox’s proxy voting mechanics to better align them with best practice in a contested election is an essential first step and one that needs to be addressed before the 2018 AGM.

The Mellanox board believes that shareholders will place far greater value on the freedom to choose the board they want, without fear of unintended consequences, than on what amounts to a brief delay in the company’s historical AGM schedule.

Executing Our Long-Term Growth Strategy to Deliver Shareholder Value
Mellanox employs a careful and thoughtful approach to investing and planning and, as our past investments continue to yield impressive results, we remain well-positioned to further benefit from our long-term growth strategy.

With a total addressable market size of approximately $10.6 billion1 forecasted in 202 (1), the Ethernet segment represents a highly attractive growth opportunity for the company. We began investing in R&D efforts related to Ethernet technology in 2013. The Ethernet design wins we are now seeing across our product suite are the rewards of our focus on innovation through R&D and investing in the future. This focused investment strategy has enabled us to outpace our competitors since 2010, with Mellanox now being the leader in innovative end-to-end solutions for connecting servers and storage platforms, holding the #1 or #2 position in many of the key markets in which we operate.

In fiscal 2017, the company made significant strategic investments to complete its data center-focused portfolio.

Specifically:
• Improving IB competitive strength in AI and HPC markets through IB 200Gb/s generation, to be introduced shortly;
• Developing the BlueField family of products from our EZchip acquisition, which provides Mellanox access to a $2 billion addressable SoC market (2); and
• Increasing the deployment of Spectrum Ethernet Switch platforms.

Strongly Positioned to Continue Realizing the Benefits of Our Prior Investments
Our emphasis on R&D has enabled us to create the most cutting-edge solutions in the industry, resulting in consistent revenue growth, averaging 27% on a pro forma basis since the company’s IPO in 2007. Our fiscal 2017 results demonstrate the successful execution of our multi-year revenue diversification strategy and our leadership position in 25Gb+ Ethernet adapters. Notably, our Ethernet switch business in the 25Gb+ segment grew 41% sequentially in the fourth quarter of 2017, as customers around the world increasingly adopted our Ethernet products.

These trends are holding firm, and customer transition from 10Gb/s to 25Gb+ Ethernet adapters is accelerating across the board – we believe in large part due to Mellanox.

We foresaw this industry shift, which is why we made the right investments and worked so diligently to position our business to have the technology and capacity to capture market share and meet demand when the transition began.

In fact, we recently raised our guidance estimates for the first quarter of 2018. Based on the mid-point of our guidance, we expect to deliver around 30% year-over-year growth in revenue and 11% operating margin expansion. Importantly, our strong financial performance was a direct result of the investments we made years before in 25Gb+ Ethernet technology.

Executing a Disciplined Campaign
to Dramatically Drive Operating Margin Improvements
Mellanox is also focused on expanding market share and improving operating margins. We are committed to achieving these objectives, while maintaining our competitive advantage of superior technology for the long term. We are rationalizing our product portfolio and focusing our investment on businesses with the greatest potential for growth and highest ROI capital. Due to our ongoing cost-cutting initiatives, we continue to reduce our operating expenses. Recently, we announced that we are ceasing investment in a new generation of network processing family of products, and discontinuing our development in 1,550nm silicon photonics.

The board and management team are fully focused on executing the company’s strategy of driving sustainable growth, which we are seeing in the accelerated adoption of key products across the customer base, while at the same time delivering on our commitment to more efficiently manage costs. In line with our strategy, we plan to end fiscal 2018 with operating margins in the 20%+ range. And as we scale faster with our Ethernet solutions, we anticipate growing and driving further efficiencies to reach operating margins in the 30s.

Mellanox is, and Will Continue to Be, a Growth Story
Mellanox has been executing on our growth strategy, and we are delivering positive results. The tremendous growth and success we have achieved is a culmination of years of carefully planned investment, as well as a direct result of our board and management team’s extensive expertise and dedication to R&D. We are seeing significant design wins across our product suite, penetrating key markets and building traction with customers.

The value we have created over the past two quarters is the result of the widespread adoption of 25Gb+ technology in every major market around the world – a trend for which Mellanox has long anticipated and planned. In short, our R&D strategy is working and proven in our financial results.

Cost cuts can drive profitability in the short term, but they can also stifle innovation and growth and have limited upside over the long term, particularly if they are undertaken to meet specific operating margin targets and not with a view towards sustainable value creation. Growth takes vision, time, investment, expertise and patience – but the upside is significant and more sustainable than financial engineering. That is the true long-term value we are creating at Mellanox for all shareholders.

New Independent Directors Further Enhance Our Diverse, Highly-Qualified Board
Committed to Shareholder Value Creation
Mellanox has a diverse and experienced board that is actively engaged in overseeing the execution of our strategy to continue to increase revenue, expand market share and improve our operating margins. Our board is composed of 11 highly qualified and experienced directors, nine of whom are independent and all of whom are seasoned leaders committed to driving shareholder value.

Notably, our board recently welcomed two new, independent directors, Steve Sanghi and Umesh Padval, concluding our search that began last year to fill two vacant board seats. As CEO of Microchip since 1991, Steve has established himself as one of the best operators in the semiconductor industry with a proven ability to drive profitable growth and value creation. Since joining the board of Integrated Device Technology in 2008, Umesh has seen significant operating margin expansion and stock price appreciation, resulting in over 5x market cap growth during his tenure. Each is a skilled and deeply knowledgeable leader who brings new perspectives and extensive semiconductor industry knowledge to our team. We are confident that their leadership abilities will be invaluable to Mellanox as we continue to execute on our strategic plan.

EGM Will Ensure That Your Voice Will Be Heard
Rushing into an AGM with our existing voting policies puts our company, shareholders and progress at risk. Mellanox, like many Israel-domiciled corporations, does not have articles of association that provide for a fair and transparent contested election. The unintended consequences of rushing into an AGM without first solving for the majority vote standard and establishing a universal proxy card could be exploited at the expense of Mellanox and its shareholders.

This year’s EGM was scheduled on approximately the same timeline as our 2017 uncontested AGM. In light of the requirement to hold the EGM first, the AGM has been pushed out. Following the EGM, we intend to immediately begin the process of scheduling the AGM, which we anticipate holding on July 25, 2018, in accordance with the Israeli Companies Law and Mellanox’s articles of association.

The Mellanox board of directors will be sending you proxy materials shortly so that you can vote to approve these best-in-class governance proposals: establishing plurality voting and requiring the use of universal proxy cards in the event of contested elections. Preliminary copies of the proxy materials have been filed with the U.S. SEC and are publicly available on our website at ir.mellanox.com/financials.cfm.

The Mellanox board is committed to building and protecting your investment by holding the EGM promptly and taking the steps necessary to align our governance policies with your interests and ensure that the composition of our Board fairly reflects shareholders’ intentions.

On behalf of your board of directors, thank you for your continued support.

Sincerely,

Irwin Federman, COB
