A Message from Omar Ishrak

To: All WW Employees

Subject: Reflections on 2014

Dear colleagues,

As I pause to reflect on everything we have accomplished in the past year, I am amazed by the progress we have made toward transforming the company and extending our Mission for people around the world.

We have a lot to be proud of in 2014. We continued to execute on our three primary growth strategies of therapy innovation, globalization and economic value. We achieved several unique, industry-leading product and technology milestones that are improving clinical outcomes and advancing patient care. We are addressing healthcare needs in emerging markets in both traditional and non-traditional ways, looking to get closer to our customers and create new business models to provide access for underserved populations. And we are building economic value into our product development processes and assessing the potential of current offerings across our portfolio to determine where the quantification of economic value will drive further adoption, increased share or price differentiation.

In addition to these strategic advancements, we have announced a number of key acquisitions and strategic alliances that are strengthening and broadening our reach in many ways. Covidien was, of course, the most significant. This represents a truly transformational opportunity – one through which we can further address the universal healthcare needs to improve clinical outcomes, expand global access and optimize cost and efficiency of health systems. The sheer breadth and depth of our offerings and expertise of our global employee base once we are a combined company will help us immediately accelerate our growth strategies and further deliver on our Mission. This is important and challenging work – and I want to recognize the incredible efforts, extra time and dedication that is required of so many employees.

Finally, and importantly, we executed on our external commitments. We mitigated significant headwinds throughout the year, by working as a team to find ways to offset these challenges. We can never lift our guard on execution and there are areas where we still need to improve, but we continue to make progress and improve our external credibility.

Every one of you contributes to the unparalleled global team at Medtronic – and I am continually both impressed and humbled to lead such a dedicated group of people working toward a common purpose. To draw from one of the many important themes of our Mission, I commend your ongoing efforts “to be the unsurpassed standard of comparison and to be recognized as a company of dedication, honesty, integrity and service.”

On December 12, I hosted the annual celebration of our Mission, the Employee Holiday Program. This was a wonderful opportunity to hear from several patients and their families about how Medtronic’s innovative technologies have transformed their lives. Many of their stories focused on what


happened after their health had been restored – including personal milestones they may have never achieved and life events that they would have missed had it not been for Medtronic technologies. Ron Brown, a 40-year Medtronic patient, took this opportunity to thank Medtronic employees on behalf of every patient around the world who feels they have been given an extra gift of life as a result of Medtronic technology and solutions. This was a reminder that these stories reach beyond a handful of lives restored, and are representative of the more than 10 million patients whose lives we touched this year.

In closing, I would like to attempt a similarly far-reaching thank you. On behalf of our entire leadership team, I want to thank each and every one of you for your dedication and hard work in 2014. We may not know about every individual accomplishment or every story about the daily work each of you contribute to our drive our overall success, but they are meaningful contributions just the same – and your consistent execution has led us to one of the most successful and impactful years we have ever achieved as a company. Whether for a customer, a patient, a caregiver, or a fellow employee, your work has made a difference.

As the year draws to a close, I hope you are all able to relax, reflect on your accomplishments, and enjoy some time with your loved ones. I wish all of you health and happiness in 2015.

Sincerely,

Omar Ishrak
