Mallinckrodt to acquire Ikaria in $2.3 bln deal. Early investor Aravis Exits along side with PE Madison Dearborn

Zurich, 9.3.2015 - Ikaria is being sold for $2.3 billion to global biopharmaceutical company Mallinckrodt.

In 2005 Aravis, through its Biotech venture I fund, had joined the initial Series A financing of Ikaria Inc, together with 5am, Venrock and Arch. Over time through various innovative M&A and financing steps the company has grown into a highly profitable specialty company. The purchase by Mallinckrodt follows last years’ partial sale to Madison Dearborne and the listing of Ikaria’s spin out Bellorophon (BLPH; NASDAQ).

This transaction represents one of the largest acquisitions of a US biotechnology company in 2015. The Ikaria story once again demonstrates the ability of Aravis to invest early in highly innovative platform technologies backed by strong syndication partners generating superior returns. Ikaria will deliver an outstanding return to Aravis Venture I LP, significantly contributing to the fund’s excellent performance.

Specialty biopharmaceutical company Mallinckrodt has agreed to acquire Ikaria for $2.3 billion and is expected to close in the second quarter of 2015.

Ikaria is a critical care company that develops and commercializes therapies designed to address the needs of critically ill patients. Ikaria’s lead product is INOMAX (nitric oxide) for inhalation, which is the only FDA-approved drug for the treatment of hypoxic respiratory failure associated with pulmonary hypertension in infants born at or near term.

Mallinckrodt has approximately 5,500 employees based in 65 countries worldwide. The company’s fiscal 2014 revenue totaled $2.5 billion. Mallinckrodt has corporate offices in St. Louis and Dublin (

“At Ikaria our mission has been to address the high unmet needs of critical care medicine,” said Daniel Tasse, Chairman and Chief Executive Officer of Ikaria. "We thank Madison Dearborn and our other investors for their partnership and believe Mallinckrodt is the natural owner of Ikaria and can expand further our mission of advancing critical care.”
