MESSAGE FROM CEO (Covidien All Employee Email)

Dear Colleagues,

On behalf of our Board of Directors and senior leadership team, I am pleased to announce that we have entered into a definitive agreement to be acquired by Medtronic, Inc., a global leader in medical technology, services and solutions [link to press release]. The proposed transaction will significantly advance the combined company’s position as the world’s premier medical technology and services company with revenues of more than $27 billion.

Medtronic offers an extensive portfolio of therapy, procedural and systems innovations, including treatments for heart disease, diabetes and chronic pain. Together, our combined company will be able to reach more patients in more ways around the world under a single mission, to alleviate pain, restore health and extend life for patients around the world.

Many of us will be reflecting on this announcement and what it means to each of us. Since we became a publicly traded company seven years ago, we have made tremendous progress and each of you should be proud of the contributions you have made. Joining with Medtronic marks the next chapter in our journey. It is a tremendous opportunity to accelerate our ability to achieve our vision of providing innovative solutions that improve patient outcomes, lower the cost of healthcare delivery and expand global access to care.

After completion of the transaction, which is anticipated, subject to satisfaction of certain conditions, to occur later this year or early next year, our newly combined company will be incorporated in Ireland, where we are currently incorporated today and will be called Medtronic plc. We will be led by Omar Ishrak, current Chairman and CEO of Medtronic.

While the combination of our companies will bring together many complementary products, it is important to note that there is relatively little overlap between our sales, marketing and R&D organizations. As we move forward, I would like to underscore that until the closing of this transaction, we will continue to operate as an independent company. That means each of us has an important responsibility to continue to deliver results to our customers, patients and shareholders, and meet our commitments for this quarter and the fiscal year.

We, along with Medtronic, are dedicated to making this transition as smooth as possible and recognize that you may have many questions regarding what this means for you and your business or function. Town hall meetings will be occurring throughout the world in the coming days, to give you the opportunity to hear from your leaders regarding the transaction and ask questions. In the meantime, please review the materials on the Pulse [link to web site with video message, FAQs, Medtronic fact sheet, press release] and if you have any immediate questions or concerns, please share them with us by [clicking the following link [insert link]] OR sending an e-mail to Corporate.Communications@covidien.com. If you are approached by the media in the coming days, please courteously refer them to Peter Lucht (peter.lucht@covidien.com) or Lisa Clemence (lisa.clemence@covidien.com) in Corporate Communications.


I look forward to combining Covidien and Medtronic and bringing two world class companies together to improve patient care around the world.

Best,
