Medtronic / Covidien

Medical-device maker Medtronic Inc. announced June 15 it would purchase Dublin-based Covidien in a $42.9 billion deal that would move the combined company to Ireland. The agreement calls for Medtronic to pay $35.19 in cash and 0.956 of a Medtronic share for each Covidien share—a 29 percent premium over the Irish medical-device maker’s closing price on June 13, the last day of trading before the announcement.
