MALLINCKRODT PLC ANNOUNCES SHARE REPURCHASE PROGRAM

DUBLIN (January 23, 2015) - Mallinckrodt plc (NYSE: MNK) announced today that its Board of Directors has approved a share repurchase program. The open-ended authorization permits the company to repurchase up to $300 million of Mallinckrodt plc ordinary shares.

"Funding additional initiatives and seeking attractive business development opportunities remain top priorities as we continue to pursue a range of focused growth strategies," said Mark Trudeau, Chief Executive Officer and President of Mallinckrodt. "This authorization reflects our strong financial position and commitment to a disciplined capital allocation strategy while reaffirming our confidence in the company's outlook and long-term potential. It also gives us the flexibility to execute share repurchases in a measured and opportunistic manner over time."

Under the share repurchase program authorized by the Board, the company's ordinary shares may be purchased through any one or more of discretionary purchases on the open market, a 10b5-1 trading plan, block trades, accelerated share repurchases or privately negotiated transactions. The number of shares repurchased and the timing of repurchases will depend on a number of factors, including share price, trading volume and general market conditions, along with working capital requirements, general business conditions and other factors. The repurchase authority may be suspended, modified or discontinued at any time, subject to the parameters of any 10b5-1 trading plan, if applicable, that the company may implement.
