    DUBLIN--(BUSINESS WIRE)--Nov. 6, 2013--
      Today, Mallinckrodt plc (NYSE: MNK) celebrates its official launch as a
      public limited company (plc) in Ireland, as well as the 20th anniversary
      of the opening of its Dublin manufacturing plant at its facilities in
      Damastown Industrial Park. The event – whose honored guests include Leo
      Varadkar, M.D., T.D., Minister for Transport, Tourism and Sport for the
      Government of Ireland, and Mark Trudeau, President and CEO of
      Mallinckrodt – celebrates the global specialty pharmaceuticals company
      strong Irish heritage and its commitment to driving future growth and
      manufacturing excellence.
    
      Over the span of two decades of operations in Ireland, Mallinckrodt has
      employed hundreds of local citizens and made investments in the
      community at large. The company’s manufacturing facility produces a
      major bulk active pharmaceutical ingredient for contrast media,
      manufactures clinical-trial material and performs drug product release
      for imaging and pharmaceutical products for markets in Europe.
    
      Mallinckrodt has also been an active supporter of JobBridge, the
      government-sponsored internship placement program, for the past 18
      months. Through JobBridge, these interns have developed and enhanced
      their skills at Mallinckrodt’s state-of-the-art facilities.
    
      “We are incredibly proud of our long-standing presence in Ireland, the
      investment we have made in the local community and our talented staff
      who embody quality, integrity and service every day,” said Mr. Trudeau.
      “Our Dublin plant is one of the top-performing sites within
      Mallinckrodt, and a key growth driver as we continue to unlock our
      potential as a leading global specialty pharmaceuticals company.”
    
      To date, Mallinckrodt has made a capital investment of more than €100
      million, and plans to grow in the years ahead. Building on its
      commitment to deliver the highest level of quality products and services
      reliably and safely, the company is developing the Dublin plant as a
      knowledge centre of excellence within Mallinckrodt for continuous
      improvement processes.
    
      “The healthcare industry offers continued potential to create jobs and
      grow our economy, as well as contribute to the health and well-being of
      our citizens,” said Minister Varadkar. “Mallinckrodt’s investment in and
      partnership with the Irish community is a valued example of this. We
      look forward to 20 more years together, and beyond.”
    
      In Dublin, Mallinckrodt employs more than 100 individuals in its
      Principle Executive Office and Manufacturing Facility. The
      82,000-square-foot state-of-the-art, facility has produced ioversol, a
      bulk active pharmaceutical ingredient for contrast media,
      since 1993.
    
      Mallinckrodt became a plc in January 2013, to hold the pharmaceuticals
      business of Covidien, which was spun off on June 28, 2013.
