Integration Planning Team Leadership Announced

The pending combination of Medtronic and Covidien announced in June represents a tremendous opportunity to create the world’s premier medical technology, services and solutions company.

Immediately following the acquisition announcement, both companies began planning the integration process. To that end, the companies have created a joint organization – the Integration Management Office (IMO) – to drive the integration planning efforts during the period leading up to the close of the transaction (expected in the fourth quarter of 2014 or early 2015) and executing the integration in the post-closing period.

As the IMO organizational snapshot below shows, a Joint Steering Committee (JSC), comprised of Medtronic and Covidien senior leaders, oversees the IMO, which is jointly led by Geoff Martha (Medtronic) and Bill Burke (Covidien). The IMO is charged with analyzing the capabilities, processes and people that will best serve the combined company when the proposed acquisition closes.

Co-leaders who will head IMO work streams in the areas of Strategy, Finance, Communication and Organization have also been named for Medtronic and Covidien. These individuals will be supported by colleagues in their respective functions with the goal of successfully launching the new Medtronic on its first day of operation (see chart below).

Over the next few weeks, the IMO will be launching teams of subject matter experts to develop detailed integration plans for functions, businesses/products and regions. Each of these teams will be jointly led by Medtronic and Covidien leaders. Their focus will be to ensure integration readiness immediately after closing. The names of those leaders will be announced shortly.

In a joint announcement, Geoff Martha and Bill Burke said: “As our respective teams have come together for this integration planning, we have realized the passion we share for patients around the world. By putting patients’ interests first, we know we will succeed in our efforts to transform healthcare.

“Finally, it is important to reiterate that we are in the planning stage and we must continue to operate as independent companies and stay focused on delivering on our current commitments to customers, shareholders and patients.”
