CARDIOVASCULAR SYSTEMS, INC. REPORTS FISCAL 2023
FIRST QUARTER FINANCIAL RESULTS

Conference Call Scheduled for Today, November 3, 2022, at 8:00 a.m. CT (9:00 a.m. ET)

Revenues of $59.7 million increased 2.2% compared to first quarter last year
Management reiterates fiscal 23 revenue guidance of $255 million to $265 million, representing 8% to 12% growth

St. Paul, Minn., November 3, 2022 – Cardiovascular Systems, Inc. (CSI®) (NASDAQ: CSII), a medical device company developing and commercializing innovative interventional treatment systems for patients with peripheral and coronary artery disease, today reported financial results for its first quarter, ended September 30, 2022.

Executive Commentary – Scott Ward, Chairman, President and CEO
“We are pleased with the state of our business and our performance in the first quarter. Q1 revenue of $59.7 million represented 2.2% revenue growth compared to last year. Worldwide coronary revenue increased 7.9% and worldwide peripheral revenue decreased less than 1%.

“Fiscal Q1 is typically our lowest revenue quarter of the year due to lower procedure volumes in the July and August timeframe. This seasonality typically results in Q1 revenue that is approximately 5 to 6 percent lower than Q4.

“Compared to Q4, Q1 revenue declined 4.5%, with worldwide coronary and peripheral revenues declining 4.0% and 4.8%, respectfully. Given historical seasonality trends, our Q1 revenue results were in line with our expectations.

“In total, we executed our commercial and R&D plans throughout the quarter and remain on track to deliver strong revenue growth and achieve key product development milestones in fiscal 23.”

First Quarter Financial Highlights
CSI’s fiscal 2023 first quarter revenues were $59.7 million, representing an increase of $1.3 million, or 2.2% compared to the first quarter last year. Gross profit margin was 72.0%.

Selling, general and administrative expenses were $44.5 million, an increase of $2.6 million, or 6.3%. Research and development expenses decreased 9.6% to $9.1 million due to the timing of development activities.

First-quarter net loss of $10.6 million, or $0.27 per basic and diluted share, compared unfavorably to a loss of $8.6 million, or $0.22 per basic and diluted share in the prior year period. The Adjusted EBITDA loss increased to $5.2 million from $1.2 million in the prior year.

As of September 30, 2022, CSI had cash and marketable securities totaling $143.7 million and no long-term borrowings.

Fiscal Year 2023 Guidance
Ward added, “Q1 results were consistent with our expectations. As a result, we are reiterating our fiscal 23 financial guidance. This guidance assumes continued improvement in US hospital procedure volumes and no new COVID headwinds over the course of the year. We believe the market recovery combined with improving commercial execution, competitive momentum, new product introductions and international expansion will drive our annual revenue to a range of $255 to $265 million, representing 8% to 12% annual growth.”

For the fiscal year ending June 30, 2023, CSI reiterates the following guidance:
• Revenue of $255 million to $265 million;
• Gross profit as a percentage of approximately 72% to 74% of revenues;
• Research and development expenses of approximately 16% to 17% of revenues;
• Net loss in a range of 9% to 11% of revenues; and
• Adjusted EBITDA near break-even.

Webcast Scheduled for Today at 8:00 a.m. CT (9:00 a.m. ET)

About Coronary Artery Disease (CAD)
CAD is a life-threatening condition and a leading cause of death in men and women globally. CAD occurs when a fatty material called plaque builds up on the walls of arteries that supply blood to the heart. The plaque buildup causes the arteries to harden and narrow (atherosclerosis), reducing blood flow. The risk of CAD increases if a person has one or more of the following: high blood pressure, abnormal cholesterol levels, diabetes, or family history of early heart disease. According to the Centers for Disease Control and Prevention, 18 million people in the United States have CAD, the most common form of heart disease. Heart disease claims more than 650,000 lives in the United States each year. According to estimates, arterial calcium is present in 38 percent of patients undergoing a PCI. Significant calcium contributes to poor stent delivery, expansion and wall apposition leading to poor outcomes and higher treatment costs in coronary interventions when traditional therapies are used, including a significantly higher occurrence of death and major adverse cardiac events (MACE).

About Peripheral Artery Disease (PAD)
Eighteen to 20 million Americans, most over age 65, suffer from PAD, which is caused by the accumulation of plaque in peripheral arteries reducing blood flow. Symptoms include leg pain when walking or at rest. Left untreated, PAD can lead to severe pain, immobility, non-healing wounds and eventually limb amputation. With risk factors such as diabetes and obesity on the rise, the prevalence of PAD is growing at double-digit rates.

Non-GAAP Financial Measures
To supplement CSI's consolidated condensed financial statements prepared in accordance with GAAP, CSI uses a non-GAAP financial measure referred to as "Adjusted EBITDA" in this release.

Reconciliations of these non-GAAP measures to the most comparable U.S. GAAP measures for the respective periods can be found in the following tables. In addition, an explanation of the manner in which CSI's management uses these measures to conduct and evaluate its business, the economic substance behind management's decision to use these measures, the substantive reasons why management believes that these measures provide useful information to investors, the material limitations associated with the use of these measures and the manner in which management compensates for those limitations is included following the reconciliation tables.

Adjusted EBITDA$(5,244)$(1,185)


Use and Economic Substance of Non-GAAP Financial Measures Used by CSI and Usefulness of Such Non-GAAP Financial Measures to Investors
CSI uses Adjusted EBITDA as a supplemental measure of performance and believes this measure facilitates operating performance comparisons from period to period and company to company by factoring out potential differences caused by depreciation and amortization expense and stock-based compensation. CSI's management uses Adjusted EBITDA to analyze the underlying trends in CSI's business, assess the performance of CSI's core operations, establish operational goals and forecasts that are used to allocate resources and evaluate CSI's performance period over period and in relation to its competitors' operating results. Additionally, CSI's management is evaluated on the basis of Adjusted EBITDA when determining achievement of their incentive compensation performance targets.

CSI believes that presenting Adjusted EBITDA provides investors greater transparency to the information used by CSI's management for its financial and operational decision-making and allows investors to see


Cardiovascular Systems, Inc.
November 3, 2022
Page 8
CSI's results "through the eyes" of management. CSI also believes that providing this information better enables CSI's investors to understand CSI's operating performance and evaluate the methodology used by CSI's management to evaluate and measure such performance.

The following is an explanation of each of the items that management excluded from Adjusted EBITDA and the reasons for excluding each of these individual items:

-- Stock-based compensation. CSI excludes stock-based compensation expense from its non-GAAP financial measures primarily because such expense, while constituting an ongoing and recurring
expense, is not an expense that requires cash settlement. CSI's management also believes that excluding this item from CSI's non-GAAP results is useful to investors to understand the application of stock-based compensation guidance and its impact on CSI's operational performance, liquidity and its ability to make additional investments in the company, and it allows for greater transparency to certain line items in CSI's financial statements.

-- Depreciation and amortization expense. CSI excludes depreciation and amortization expense from its non-GAAP financial measures primarily because such expenses, while constituting ongoing and recurring expenses, are not expenses that require cash settlement and are not used by CSI's management to assess the core profitability of CSI's business operations. CSI's management also believes that excluding these items from CSI's non-GAAP results is useful to investors to understand CSI's operational performance, liquidity and its ability to make additional investments in the company.

Material Limitations Associated with the Use of Non-GAAP Financial Measures and Manner in which CSI Compensates for these Limitations
Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as a substitute for CSI's financial results prepared in accordance with GAAP. Some of the limitations associated with CSI's use of these non-GAAP financial measures are:
-- Items such as stock-based compensation do not directly affect CSI's cash flow position; however, such items reflect economic costs to CSI and are not reflected in CSI's "Adjusted EBITDA" and therefore these non-GAAP measures do not reflect the full economic effect of these items.

-- Non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles and therefore other companies may calculate similarly titled non-GAAP financial measures differently than CSI, limiting the usefulness of those measures for comparative purposes.

-- CSI's management exercises judgment in determining which types of charges or other items should be excluded from the non-GAAP financial measures CSI uses. CSI compensates for these limitations by relying primarily upon its GAAP results and using non-GAAP financial measures only supplementally. CSI provides full disclosure of each non-GAAP financial measure.

Reiterating FY23: Annual Guidance 9 For the fiscal year ending June 30, 2023, CSI anticipates: Revenue of $255 million to $265 million; Gross profit as a percentage of revenues of 72% to 74%; Net loss in a range of 9% to 11% of revenues; and Adjusted EBITDA near break-even. Research and development expenses of approximately 16% to 17% of revenues;


 
Non-GAAP Financial Measures 10 CSI uses Adjusted EBITDA as a supplemental measure of performance and believes this measure facilitates operating performance comparisons from period to period and company to company by factoring out potential differences caused by depreciation and amortization expense and stock-based compensation. CSI's management uses Adjusted EBITDA to analyze the underlying trends in CSI's business, assess the performance of CSI's core operations, establish operational goals and forecasts that are used to allocate resources and evaluate CSI's performance period over period and in relation to its competitors' operating results. Additionally, CSI's management is evaluated on the basis of Adjusted EBITDA when determining achievement of their incentive compensation performance targets. Beginning with the quarter ended March 31, 2022, following correspondence from the staff of the U.S. Securities and Exchange Commission, we no longer exclude in process research and development (IPR&D) charges incurred in connection with asset acquisitions from Adjusted EBITDA or any other reported non-GAAP financial measures. For purposes of comparability, we have revised the reconciliation table above for the full year of fiscal 2021. CSI believes that presenting Adjusted EBITDA provides investors greater transparency to the information used by CSI's management for its financial and operational decision-making and allows investors to see CSI's results "through the eyes" of management. CSI also believes that providing this information better enables CSI's investors to understand CSI's operating performance and evaluate the methodology used by CSI's management to evaluate and measure such performance.
