Subject: Tyco Electronics to Acquire ADC
Today we are announcing that Tyco Electronics is planning on acquiring ADC to create a world leader in broadband connectivity (link to external news release). I’m excited about the intention to bring together two dynamic organizations to form an entity that will strengthen our combined leadership positions in the marketplace for next generation broadband network infrastructure solutions.
For several years, you have heard me talk about the key trends in our industry, including the need to address the unrelenting demand for network bandwidth and the requirement for companies such as ADC to create global scale to be successful over the long term. The planned combination of Tyco Electronics and ADC strengthens our alignment with these trends and will enable us to better serve the world’s leading telecommunications services providers and enterprises.
As an ADC employee, I know that you have many questions on the impact of the proposed acquisition as this news may be unsettling. I can tell you that both companies are committed to providing you with additional information and updates as they become available. A ‘Question and Answer’ document will be available soon. I also can share with you that I’m impressed with the caliber and integrity of everyone from Tyco Electronics that I have come into contact with during our discussions. Their people, technologies and global market presence are complementary to what we have here at ADC, making this truly an exciting opportunity for both organizations and our customers.
Between the contract signing and the anticipated closing of the transaction sometime later this calendar year, both companies will be working together to plan how we will work together after close. At the same time, it is imperative that we all stay focused on our key FY10 business priorities.
As you know, ADC has achieved steadily improving results over the past year thanks to your hard work and is in an excellent position to finish the year strongly. While it



will take enormous focus and discipline to both begin the planning for the future with Tyco Electronics and maintaining our positive momentum on our FY10 business goals, I am confident we can do it successfully.
Tom Lynch, CEO of Tyco Electronics, and I will be hosting a global Town Hall webcast tomorrow at 10 a.m. (Central) to provide an overview of today’s news. (Webcast details to follow.) If you have a question you would like us to answer during the Town Hall, please send your questions to Thank you in advance for watching this event on ADC TV and I look forward to your continued support in serving our customers and meeting our FY10 strategic goals.
