Exciting Company Announcement

Greetings CSI:

In a joint press release [LINK: https://abbott.mediaroom.com/2023-02-08-Abbott-to-Acquire-Cardiovascular-Systems,-Inc] from Cardiovascular Systems, Inc. (CSI) and Abbott Laboratories [LINK: https://www.abbott.com/] (Abbott), it was announced that an agreement has been reached for Abbott to acquire CSI. While we anticipate that it will take time for this transaction to be completed, we expect that CSI will join one of the largest multinational medical device and healthcare companies.

Let me share with you why I and the CSI Board of Directors believe this is the right decision for our stakeholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We believe our **patients and customers will benefit**. We believe that our atherectomy devices fit seamlessly into Abbott's existing coronary and peripheral intervention technologies that include guidewires, catheters, stents, closure devices, imaging systems and more – tools that are routinely used before, during and after atherectomy procedures. Combined, we believe that our complementary technologies will enable Abbott to provide physicians with more tools to help patients with complex peripheral vascular and coronary artery disease. Over time, we believe our R&D product pipeline will advance patient care while adding promising new technologies to Abbot Vascular's [LINK: https://www.cardiovascular.abbott/us/en/home.html] growing coronary and peripheral offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• This acquisition brings together two talented teams as we execute our plan to grow our core business and diversify our product offering. Abbott has a global presence in medical devices, diagnostics, pharmaceuticals and nutrition, providing employees with **attractive career growth opportunities**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• At closing, this transaction will provide CSI stockholders with a cash payment at a premium to our pre-announcement share price.

------

I know many of you will have questions and we encourage you to access the Frequently Asked Questions (FAQ) on our dedicated 360View intranet site and attached above. Please consider 360View as a hub for all available information on this announcement. In addition, we encourage you to visit Abbott's corporate website [LINK: https://www.abbott.com/] to learn more about the company.

Acquisitions like this typically take time for regulatory and legal approval. During this transition period we will continue to operate our business in accordance with our normal business cadence and practices. We will:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• remain focused on our FY23 goals;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• continue to live CSI's core values of Accountability, Community, Courage, Excellence, Integrity and Velocity; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pursue our Mission to Save Limbs, Save Lives, Every Day.

We have always navigated transitions within our business with perseverance and passion. I have no doubt the same will be true here because we have the privilege of serving a higher purpose…our patients.

Thank you for your ongoing commitment to our Mission and each other.

Scott

Hello [NAME],

In a joint press release [LINK: https://investors.csi360.com/news-releases/press-release-details/2023/Abbott-to-Acquire-Cardiovascular-Systems-Inc/default.aspx] from Cardiovascular Systems, Inc. (CSI) and Abbott Laboratories [LINK: https://www.abbott.com/] (Abbott), it was announced that an agreement has been reached for Abbott to acquire CSI. While we anticipate that it will take time for this transaction to be completed, we expect that CSI will join one of the largest multinational medical device and healthcare companies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We believe our patients and customers will benefit. We believe that our atherectomy devices fit seamlessly into Abbott's existing coronary and peripheral intervention technologies that include guidewires, catheters, stents, closure devices, imaging systems and more – tools that are routinely used before, during and after atherectomy procedures. Combined, we believe that our complementary technologies will enable Abbott to provide physicians with more tools to help patients with complex peripheral vascular disease and coronary artery disease. Over time, we believe our R&D product pipeline, will advance patient care while adding promising new technologies to Abbott Vascular [LINK: https://www.cardiovascular.abbott/us/en/home.html] growing coronary and peripheral offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Abbott is recognized by several institutions as a leading healthcare company and has earned consistent recognition as a best place to work in many countries around the world. In addition, Abbott has a global presence in medical devices, diagnostics, pharmaceuticals and nutrition, providing employees attractive career growth opportunities.

We continue to welcome the opportunity for you to join CSI and be part of this next chapter. However, I know you will have questions. As such, Jim Belmonte, Director of Talent Management, will be reaching out over the course of the next couple of days to answer what we can so that you can make an informed decision.

Thank you,
