Abbott to Acquire Cardiovascular Systems, Inc.

• Abbott will gain an innovative, complementary solution in treating vascular disease through CSI's leading atherectomy system, which prepares vessels for angioplasty or stenting to restore blood flow
• CSI's offering will support Abbott's ability to provide better care for patients with peripheral and coronary artery disease

Abbott (NYSE: ABT) and Cardiovascular Systems, Inc. (CSI), today announced a definitive agreement for Abbott to acquire CSI, a medical device company with an innovative atherectomy system used in treating peripheral and coronary artery disease. Under terms of the agreement, CSI stockholders will receive $20 per common share at a total expected equity value of approximately $890 million .

CSI is a leader in devices for atherectomy, a minimally invasive treatment for plaque build-up in arteries that can restrict blood flow. Procedural use of atherectomy can help maximize the benefits of standard balloon angioplasty or stent treatments in restoring blood flow in complex arterial disease. CSI also has an early-stage pipeline of complementary vascular intervention devices in development.

"The acquisition of CSI will add new, complementary technologies to Abbott's leading vascular device offerings," said Lisa Earnhardt , executive vice president, Medical Devices, Abbott. "CSI has a talented and experienced team and a leading atherectomy system that will allow Abbott to provide physicians more tools to help patients live fuller lives."

"We are pleased to have reached an agreement with a leading global company that shares our passion for the development and commercialization of innovative solutions for treating complex peripheral vascular disease and coronary artery disease," said Scott Ward , CSI's chairman, president and chief executive officer. "We believe combining with Abbott delivers value to our patients, physician customers, employees and stockholders while continuing our work to save limbs and save lives every day."

Financial Impact of Transaction

Upon close, the transaction is expected to be neutral to Abbott's recently issued 2023 ongoing earnings per share guidance.

The transaction, which has been approved by the boards of directors of CSI and Abbott, is subject to the approval of CSI stockholders and the satisfaction of customary closing conditions, including applicable regulatory approvals.

J.P. Morgan Securities LLC is serving as financial advisor to CSI.
