DUBLIN, April 16, 2015 /PRNewswire/ -- Mallinckrodt plc (NYSE: MNK), a leading specialty biopharmaceutical company, today announced that it has completed its acquisition of Ikaria, Inc. at a purchase price of approximately $2.3 billion. The Ikaria acquisition extends Mallinckrodt's footprint in the hospital market and expands its reach into neonatal critical care with INOMAX® (inhaled nitric oxide), a vital treatment option for a highly vulnerable patient population. It also accelerates Mallinckrodt's rapid growth in specialty brands -- adding significant portfolio diversity with a high-value, high-margin integrated drug-device-service product offering.

The all-cash transaction is expected to add at least $150 million in net sales and be accretive to the company's fiscal year 2015 adjusted diluted earnings per share by at least $0.25 per share.

Mallinckrodt today also announced that to support its ongoing transformation and continued rapid growth in specialty pharmaceuticals it will expand its commercial leadership to support the portfolio. Hugh O'Neill and Daniel Tassé, formerly Chairman and Chief Executive Officer of Ikaria, will serve as Mallinckrodt Commercial Senior Vice Presidents. Mr. Tassé will remain with the business until a new, permanent senior executive leader is identified, and will assist in the selection process. Both Mr. O'Neill and Mr. Tassé will serve as members of Mallinckrodt's Executive Committee and report directly to Mark Trudeau, President and Chief Executive Officer.

"This latest transaction continues the rapid transformation of Mallinckrodt into a leading specialty biopharmaceutical company and demonstrates our ongoing commitment to driving revenue and earnings growth for shareholders and delivering value for patients," said Mark Trudeau. "In the last 20 months we've not only grown quickly, but we've substantially shifted our business focus and created rich new specialty pharmaceutical growth platforms for the future. 

"To fully realize the significant potential of our new and expanded portfolio, it's critical that we increase our capacity as well as deepen and broaden our commercial capabilities.  I'm confident that intensified leadership focus will enable us to achieve our goals," concluded Mr. Trudeau.

INOMAX is a vasodilator, which, in conjunction with ventilator support and other appropriate agents, is indicated for the treatment of term and near-term (>34 weeks gestation) neonates with hypoxic respiratory failure associated with clinical or echocardiographic evidence of pulmonary hypertension, where it improves oxygenation and reduces the need for extracorporeal membrane oxygenation. INOMAX should not be used in the treatment of neonates known to be dependent on right-to-left shunting of blood. Abrupt discontinuation of INOMAX may lead to a worsening condition. Methemoglobinemia is a dose-dependent side effect of inhaled nitric oxide therapy. Nitrogen dioxide (NO2) forms rapidly in gas mixtures containing nitric oxide and oxygen, and therefore may cause airway inflammation and damage. Methemoglobin S, NO2, and FiO2 should be monitored during nitric oxide administration.
