Other Events

As previously announced, on February 8, 2023, Cardiovascular Systems, Inc., a Delaware corporation (the “Company”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Abbott Laboratories, an Illinois corporation (“Parent”), and Cobra Acquisition Co., a Delaware corporation and a direct, wholly-owned subsidiary of Parent (“Merger Sub”). Upon the terms and subject to the conditions of the Merger Agreement, Parent will acquire the Company via the merger of Merger Sub with and into the Company, with the separate corporate existence of Merger Sub thereupon ceasing and the Company continuing as the surviving corporation and a wholly-owned subsidiary of Parent (the “Merger”).

The consummation of the Merger is conditioned upon, among other things, the expiration or termination of the applicable waiting period (or any extension thereof) under the Hart-Scott Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”). At 11:59 p.m., Eastern Time, on April 12, 2023, the waiting period applicable to the Merger under the HSR Act expired. Accordingly, the condition relating to the expiration or termination of the waiting period under the HSR Act has been satisfied. The Merger continues to be subject to the remaining conditions set forth in the Merger Agreement.

Additional Information and Where to Find It

This filing has been prepared in respect of the Merger, and may be deemed to be soliciting material relating to the Merger. In connection with the Merger, CSI has filed with the Securities and Exchange Commission (the “SEC”) preliminary and definitive proxy statements relating to the Merger Agreement, the Merger, and the other transactions contemplated thereby, and other relevant documents. The definitive proxy statement was mailed on or about March 23, 2023, to CSI’s stockholders as of the close of business on March 14, 2023, the record date established for voting on the Merger Agreement, the Merger, and the other transactions contemplated thereby, and any other matters to be voted on at a special meeting of CSI stockholders as detailed in the definitive proxy statement. BEFORE MAKING ANY VOTING DECISIONS, STOCKHOLDERS ARE URGED TO READ THE DEFINITIVE PROXY STATEMENT, ANY AMENDMENTS OR SUPPLEMENTS THERETO, ANY OTHER SOLICITING MATERIALS, ANY DOCUMENTS WHICH ARE INCORPORATED BY REFERENCE IN THE DEFINITIVE PROXY STATEMENT, AND ANY OTHER DOCUMENTS FILED OR TO BE FILED WITH THE SEC IN CONNECTION WITH THE MERGER WHEN THEY BECOME AVAILABLE BECAUSE THEY CONTAIN, OR WILL CONTAIN, IMPORTANT INFORMATION ABOUT CSI, PARENT, THE MERGER AGREEMENT, THE MERGER, AND RELATED MATTERS. Stockholders are or will be able to obtain a copy of the definitive proxy statement, as well as other filings containing information about the Merger Agreement, the Merger, and the other transactions contemplated thereby that are filed by CSI with the SEC, free of charge on EDGAR at www.sec.gov or on the investor relations page of CSI’s website at www.investors.csi360.com.

Participants in the Solicitation

CSI and its directors and executive officers may be deemed to be participants in the solicitation of proxies from the stockholders of CSI in respect of the Merger. Information about CSI’s directors and executive officers is set forth in the proxy statement for CSI’s 2022 Annual Meeting of Stockholders, as revised, which was filed with the SEC on October 26, 2022, and its Annual Report on Form 10-K for the fiscal year ended June 30, 2022, which was filed with the SEC on August 18, 2022.

Other information regarding the participants in the proxy solicitation in connection with the Merger and a description of their interests, which may, in some cases, be different than those of CSI’s stockholders generally, is contained in the definitive proxy statement described above or may be contained in other relevant materials to be filed with the SEC in respect of the Merger Agreement, the Merger, and the other transactions contemplated thereby when they become available.
