ev3 To Buy Chestnut Medical

ev3 Inc. (Nasdaq:EVVV) has agreed to acquire Chestnut Medical Technologies Inc., a Menlo Park, Calif.-based developer of minimally-invasive therapies for interventional neuroradiology. The deal is valued at $75 million, of which between 30%-40% will be paid in cash. Chestnut Medical has raised over $9 million in VC funding since 2007, from firms like Synergy Partners, JAIC, Veron International and ITX International Holdings.  

PRESS RELEASE

ev3 Inc. (Nasdaq:EVVV), a global endovascular device company, today announced that it has signed a definitive agreement to acquire Chestnut Medical Technologies, Inc., a privately held, California-based company focused on developing minimally invasive therapies for interventional neuroradiology. The transaction will broaden ev3’s neurovascular product portfolio by adding the Pipeline Embolization Device for the treatment of cerebral aneurysms and the Alligator Retrieval Device for foreign body retrieval to ev3’s existing embolic product and access technologies.

Under the terms of the agreement, ev3 will acquire 100 percent of the equity interests of Chestnut for total upfront consideration of $75 million paid upon closing, 30 to 40 percent of which is payable in cash, with the remaining portion payable in ev3 common stock. An additional milestone-based contingent payment of up to $75 million is payable in a combination of cash and ev3 common stock upon the receipt of U.S. FDA premarket approval of the Pipeline device. ev3 will finance the upfront cash payment due upon closing through cash on hand. Any contingent milestone payment is not expected to be paid until 2011. The transaction is subject to customary closing conditions and is expected to close within approximately 45 days.

Robert Palmisano, president and chief executive officer of ev3, commented, “This acquisition directly supports our stated strategy of bringing breakthrough neurovascular therapies to our markets and adds an innovative new product platform to benefit the large number of patients suffering from brain aneurysms that currently are not well treated with either surgical or endovascular techniques. In addition, this acquisition is expected to be an immediate revenue contributor, leverage the strong global distribution capabilities of ev3’s neurovascular sales organization and provide another growth engine for delivering enhanced value to our shareholders.”

Chestnut’s Pipeline technology is a new class of embolization device that is designed to divert blood flow away from the aneurysm in order to provide a complete and durable aneurysm embolization while maintaining patency of the parent vessel. It has already received CE Mark approval in Europe. Chestnut is currently conducting two clinical studies under U.S. FDA investigational device exemptions (IDE) to gain approval for the Pipeline Embolization Device in the United States.

Aaron Berez, M.D., president and chief executive officer of Chestnut, added, “Chestnut Medical is delighted to partner with ev3 with whom we share a deep commitment to providing the minimally invasive tools that improve patient outcomes. We believe that our Pipeline technology is changing the way aneurysms are treated, and that ev3 with its broad global footprint is the ideal partner to accelerate the rapid diffusion of our products around the world.”

Although ev3 cannot finalize the purchase price allocation and fair value assessment of the contingent consideration until the closing and thus cannot yet assess the exact impact on its 2009 GAAP earnings, ev3 anticipates that the transaction will be dilutive to ev3’s GAAP earnings per share (EPS) and non-GAAP adjusted earnings per share in 2009 and on a GAAP EPS basis in 2010 due to the expected level of transaction-related charges, including intangible amortization expense, non-cash contingent consideration expense and the issuance of ev3 common shares. Excluding the impact of amortization and other charges associated with the accounting treatment of the contingent milestone payment, ev3 anticipates the transaction will be accretive to ev3’s non-GAAP adjusted EPS in 2010 and beyond. The transaction is expected to be neutral to ev3’s EPS on a GAAP basis in 2011 and accretive thereafter. ev3 will provide additional information on the financial impact of this transaction, including its effect on ev3’s 2009 guidance, after the closing.

“Large and giant, wide-neck or non-saccular aneurysms remain a significant unmet clinical need,” stated Saruhan Cekirge, M.D., professor of neuroradiology and interventional neuroradiology at the Hacettepe University School of Medicine in Ankara, Turkey. “Early experience suggests that the Pipeline Embolization Device may represent a valuable alternative to current endovascular or surgical treatment options for these aneurysms and that flow diversion technology may account for as many as one-fourth of the treated aneurysm patient population over the next five years.”

A cerebral aneurysm is a weak spot in the wall of a blood vessel within the brain, characterized by an abnormal “ballooning” or widening of the vessel. It is estimated that up to one in 15 people in the United States will develop a cerebral aneurysm during their lifetime. Left untreated, cerebral aneurysms can rupture and cause stroke or death. ev3 estimates that approximately one fourth of worldwide aneurysm treatment procedures could be eligible for treatment with flow diversion devices over the next five years, translating into a market potential of approximately $350 million in 2013.
