Company Description

Cardiovascular Systems, Inc. (the “Company”) was incorporated as Replidyne, Inc. (“Replidyne”) in Delaware in 2000. On February 25, 2009, Replidyne completed its business combination with Cardiovascular Systems, Inc., a Minnesota corporation, in accordance with the terms of the Agreement and Plan of Merger and Reorganization, dated as of November 3, 2008. At the effective time of the merger, Replidyne changed its name to Cardiovascular Systems, Inc.

The Company develops, manufactures and markets devices for the treatment of vascular diseases. The Company’s peripheral arterial disease (“PAD”) products, the Stealth 360°^® Peripheral Orbital Atherectomy System (“OAS”), and the Diamondback 360^® Peripheral OAS, are catheter-based platforms capable of treating a broad range of plaque types, including calcified plaque, in leg arteries both above and below the knee, and address many of the limitations associated with existing surgical, catheter and pharmacological treatment alternatives. These devices use smaller access sheaths that can provide procedural benefits and allow physicians to treat PAD patients in the small and tortuous vessels located below the knee through alternative access sites in the ankle and foot as well as in the groin.

In October 2013, the Company received premarket approval from the United States Food and Drug Administration to market the Diamondback 360^® Coronary OAS as a treatment for severely calcified coronary arteries.

The Company is currently selling only in the United States and evaluating options for international expansion to maximize the coronary and peripheral market opportunities.
