Boston Scientific announces agreement to acquire Penumbra, Inc.

Boston Scientific Corporation and Penumbra, Inc., announced the companies have entered into a definitive agreement under which Boston Scientific will acquire Penumbra in a cash and stock transaction that values Penumbra at $374 per share, reflecting an enterprise value of approximately $14.5 billion.

"Penumbra is a well-established company with an experienced, high-performing team and this acquisition offers Boston Scientific an opportunity to enter new, fast-growing segments within the vascular space," said Mike Mahoney, chairman and chief executive officer, Boston Scientific. "I'm thrilled to combine the talents and shared values of our teams – including welcoming Penumbra's chairman and chief executive officer, Adam Elsesser, to our board of directors upon close. The addition of Penumbra can expand access for these novel technologies to more patients and customers around the world, further enhancing our revenue and margins over time with proven offerings that have a history of growth and innovation."

Cardiovascular diseases are the leading cause of death globallyⁱⁱ and include disorders of the heart and blood vessels that can restrict blood flow and increase the risk of clots throughout the body. To address the escalating prevalence of these complex diseases, Penumbra has developed a comprehensive portfolio that includes differentiated devices to treat conditions such as pulmonary embolism, stroke, deep vein thrombosis, acute limb ischemia, heart attack and aneurysms.

Penumbra offers innovative mechanical thrombectomy products for use in peripheral vascular procedures to remove blood clots causing blockages in arterial, venous and pulmonary vessels, including the Lightning Bolt^® and Lightning Flash^® computer assisted vacuum thrombectomy (CAVT™) systems. The company's vascular portfolio also includes a minimally invasive peripheral embolization system, which is designed to stop blood flow to control hemorrhaging and bleeding or to close blood vessels.

Neurovascular offerings from Penumbra currently include differentiated solutions for access, stroke revascularization and neuro embolization. The company is continuing to innovate in these areas and add meaningful clinical evidence to support expanded access for more patients worldwide.

"Our decades-long development of therapies for challenging medical conditions has focused on deep innovation for complex diseases so that we can offer physicians novel solutions to transform patient care," said Adam Elsesser. "I am grateful for the amazing people who have contributed to this work and look forward to uniting our efforts and shared values as we come together with Boston Scientific."  

Penumbra expects to deliver fourth quarter reported revenue growth in the range of approximately 21.4% - 22.0% and full year 2025 reported revenue of approximately $1.4 billion, representing growth in the range of approximately 17.3% - 17.5% over the prior fiscal year.ⁱⁱⁱ Penumbra continues to advance its technologies with a multi-year research and development plan and ongoing clinical programs.

Boston Scientific expects to finance the approximately $11 billion cash portion of the transaction consideration with a combination of cash on hand and new debt. The transaction is expected to be $0.06-0.08 dilutive to adjusted earnings per share for Boston Scientific in the first full year following the close of the acquisition, neutral to slightly accretive in the second year and more accretive thereafter. The impact to GAAP earnings per share is expected to be dilutive in the first full year following the close, and less dilutive or increasingly accretive thereafter, as the case may be, due to amortization expense and acquisition-related net charges.
