Subject Company: Orbotech Ltd.

Commission File No.: 000-12790


Dear All,

I am pleased to announce an exciting development for Orbotech. Today KLA-Tencor, the California based leading provider of semiconductor process control and yield management solutions and Orbotech have announced their intentions for KLA-Tencor to acquire Orbotech.

KLA-Tencor’s keen interest in Orbotech is a recognition of the huge success we have made throughout the years and in our significant recent growth story. KLA-Tencor sees Orbotech as a genuine asset in their future strategy, one that will open up new markets and product lines, which add value to their offering, their customer proposition and enables their diversification strategy.

Orbotech is more than a company – it is, has been and will continue to be a special place to many of its employees and it has provided our customers and their ecosystems with truly industry leading solutions across the electronics value chain.

While considering this significant step, we have been very careful in making sure that we only have accepted an offer of a company that:


    not only understands our culture / DNA / talent and wants to nurture and build a growth story on its basis, but which shares similar values and cultural characteristics,


    has complementary technologies,


    is committed to the ongoing operation of the Orbotech business group, under the brand of Orbotech in its current locations,


    has expressed confidence in both the management team and all of our employees’ commitment to the 2020 plan.

Orbotech has huge growth potential – as I have previously announced to you and our investors in our 2020 plan. It is a challenging plan with significant investments required in markets, products, advanced technology, innovation and customer experience efforts. Having considered these challenges, both KLA-Tencor and Orbotech believe we will be able to meet the increasingly sophisticated needs of our customers and our industry challenges more effectively by leveraging our best practices and sharing the burden of investment together. I ask each one of you to remain committed and focused on that plan.

We will be working very closely with KLA-Tencor as we move forward with this transition based on the aligned vision and set of strategic principles we have developed.

Today marks the announcement of the transaction and there will be a comprehensive communication plan during which you and our customers and partners will be briefed in more detail on what it means for us and for you specifically. During the coming days, Rick Wallace, CEO of KLA-Tencor and I will be coming to visit employees to explain the unique value and role Orbotech will play in KLA-Tencor’s future.



For the coming months, the transaction will move forward with obtaining necessary shareholder and regulatory approvals. We expect the acquisition to close by the fourth quarter of 2018. During this period, we will commence the integration planning process I mentioned above but we continue to operate as a separate entity and (I must emphasize this point) we continue full speed ahead with our 2018 business plans. Please do not meet with KLA-Tencor employees, customers, or suppliers unless you are specifically instructed to.

As I mentioned above, KLA-Tencor’s interest in Orbotech is a true testimony to what we have been able to achieve and I am very proud of what we have built together. We are the result of very hard work and personal contributions by so many of you. Today marks the next step in our journey – one I believe will lay the foundation for great opportunity and success.

I look forward to seeing you in the coming days and please refer to this link for a more detailed set of Q&As.
