You should read the following discussion and analysis of our financial condition
and results of operations together with our financial statements and the related
notes appearing under Item 1 of Part I of this Quarterly Report on Form 10-Q.
Some of the information contained in this discussion and analysis or set forth
elsewhere in this Quarterly Report on Form 10-Q, including information with
respect to our plans and strategy for our business and expected financial
results, includes forward-looking statements that involve risks and
uncertainties. You should review the "Risk Factors" discussed in our Annual
Report on Form 10-K for the year ended June 30, 2021 and subsequent Quarterly
Reports on Form 10-Q, including in Item 1A of Part II of this Quarterly Report
on Form 10-Q, for a discussion of important factors that could cause actual
results to differ materially from the results described in or implied by the
forward-looking statements contained in the following discussion and analysis.

OVERVIEW



We are a medical technology company leading the way in the effort to
successfully treat patients suffering from peripheral and coronary artery
diseases, including those with arterial calcium, the most difficult form of
arterial disease to treat. We are committed to clinical rigor, constant
innovation and a defining drive to set the industry standard to deliver safe and
effective medical devices that improve the lives of patients facing this
difficult disease state. We have developed patented orbital atherectomy systems
("OAS") for both peripheral and coronary clinical applications. The primary base
of our business is catheter-based platforms capable of treating a broad range of
vessel sizes and plaque types, including calcified plaque, which address many of
the limitations associated with other treatment alternatives.

In the past, we have observed some degree of seasonality in our business, as
there tends to be a lower number of procedures that use our products during the
three months ending September 30. Interventional procedure volume usually grows
throughout the course of the fiscal year, with the quarter ending June 30
representing the highest volume of cases and, therefore, the highest amount of
revenue generated by us during the course of the fiscal year. While we did not
experience this same pattern of seasonality in the three months ended September
30, 2020 due to the significant decrease in procedure volumes in the quarter
ended June 30, 2020 due to the COVID-19 pandemic, we did experience this pattern
of seasonality in the three months ended September 30, 2021, compared to the
three months ended June 30, 2021. The three months ended June 30, 2021 benefited
from a recovery from the COVID-19 pandemic, and the volume of procedures
involving our products in the three months ended September 30, 2021 was
adversely impacted primarily by hospital capacity constraints due to increased
hospitalizations caused by the COVID-19 Delta variant, as well as disruption of
referral patterns, deferral of elective procedures, staffing shortages and
heightened summer seasonality in the quarter.

Peripheral



Our peripheral artery disease ("PAD") products are catheter-based platforms
capable of treating a broad range of plaque types in leg arteries both above and
below the knee, including calcified plaque, and address many of the limitations
associated with other existing surgical, catheter and pharmacological treatment
alternatives. The micro-invasive devices use small access sheaths that can
provide procedural benefits, allow physicians to treat PAD patients in even the
small and tortuous vessels located below the knee, and facilitate access through
alternative sites in the ankle, foot and wrist, as well as in the groin.

The United States Food and Drug Administration ("FDA") has granted us 510(k)
clearances for our Peripheral OAS as a therapy in patients with PAD, as
discussed in Item 1 of Part I of our Annual Report on Form 10-K for the year
ended June 30, 2021. We refer to these products in this Quarterly Report on Form
10-Q as the "Peripheral OAS." In addition to our Peripheral OAS, we also offer
support products within the peripheral space. Peripheral sales in the United
States during the three months ended September 30, 2021 represented 66% of
revenue.

Coronary



Our coronary artery disease ("CAD") product, the Diamondback 360 Coronary OAS
("Coronary OAS"), is a catheter-based platform designed to facilitate stent
delivery in patients with CAD who are acceptable candidates for percutaneous
transluminal coronary angioplasty or stenting due to de novo, severely calcified
coronary artery lesions. The Coronary OAS design is similar to technology used
in our Peripheral OAS, customized specifically for the coronary application. In
addition to the Coronary OAS, we also offer support products within the coronary
space as we expand treatment to a broader patient population with complex
coronary artery disease.

                                       18
--------------------------------------------------------------------------------
  Table of Contents
We have received premarket approval ("PMA") from the FDA to market the Coronary
OAS as a treatment for severely calcified coronary arteries. Coronary sales in
the United States during the three months ended September 30, 2021 represented
approximately 28% of revenue.

International

We serve a growing patient population globally through an expanding distribution
and sales network. Sales of our approved products in Japan are made through our
exclusive Japan distributor, Medikit Co., Ltd. ("Medikit"). Sales of our
products in the rest of the world, which primarily includes certain countries in
Southeast Asia, Europe and the Middle East, are made through a network of
distributors and sales agents. International sales during the three months ended
September 30, 2021 represented approximately 6% of revenue.

Impact of COVID-19



The COVID-19 pandemic in the United States and internationally has caused us to
experience ongoing disruptions in the procedures using our products. Procedures
have been postponed, and may continue to be postponed, as a result of reduced
availability of physicians or lab space to treat patients, the lack of personal
protective equipment and active virus test kits, different treatment
prioritizations, increased cost pressures and burdens on the overall healthcare
infrastructure that result in reallocation of resources, customer staffing
shortages, and governmental guidelines and restrictions. In addition, patients
have elected to defer or avoid treatment for procedures that use our products
due to anxiety about the potential spread of COVID-19 in facilities. Finally,
our personnel and the personnel of our distribution partners experienced
restrictions on their ability to access many customers, hospitals, labs and
other medical facilities for sales activities, training and case support as they
may have been deemed to be "non-essential" personnel by those facilities, and
there has been a reduction in procedure activity in these accounts.

In addition to the impact on procedure volumes, we experienced other disruptions
as a result of the COVID-19 pandemic. For example, enrollment in our ECLIPSE
clinical trial was paused for several months. Other disruptions included
restrictions on the ability of our personnel and personnel of our distribution
partners to travel; delays in approvals by regulatory bodies; delays in product
development efforts, which has also disrupted or delayed our ability to launch
affected products; reallocation of company resources from our strategic
priorities; supply chain disruptions that limited, delayed or prevented us from
acquiring the components used to develop and manufacture our products or ship
those products once manufactured; disruptions in our relationships with our
distributors due to the impact of the COVID-19 pandemic on their operations;
temporary closures of our facilities; loss of employee productivity; and
additional government requirements to "shelter at home" or other incremental
mitigation efforts that may further impact our capacity to manufacture, sell and
support the use of our products.

Throughout the pandemic, we have operated our manufacturing facilities and
continued to ship product. Most of our office-based employees telecommuted, and
our field employees continued to support cases in clinical settings where they
were able to have access. We took several actions intended to protect the health
and well-being of our workforce and our customers. We will continue to monitor
developments at the local, state and national levels in order to ensure that we
and our employees have current information for purposes of making decisions in
the dynamic and unpredictable environment and that we comply with applicable
requirements.

We are monitoring the spread of variants, including the Delta variant, and
continue to track hospitalizations resulting from these variants. Many factors
may increase or decrease procedure volumes, which would have an impact on our
revenue and financial results, including vaccination levels and mandates, the
spread of new, more viral or deadly variants of the SARS-CoV-2 virus, easing of
social restrictions and government restrictions on elective and semi-elective
cases, level of patient anxiety, medical facility and workforce capacity, and
sales representative access to facilities to support cases.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT JUDGMENTS AND ESTIMATES



Our management's discussion and analysis of our financial condition and results
of operations is based on our consolidated financial statements, which have been
prepared in accordance with accounting principles generally accepted in the
United States. The preparation of our consolidated financial statements requires
us to make estimates, assumptions and judgments that affect amounts reported in
those statements. Our estimates, assumptions and judgments, including those
related to revenue recognition, deferred revenue and stock-based compensation,
are updated as appropriate at least quarterly. We use authoritative
pronouncements, our technical accounting knowledge, cumulative business
experience, judgment and other factors in the selection and application of our
accounting policies. While we believe that the estimates, assumptions and
judgments that we use in preparing our consolidated financial statements are
appropriate, these estimates, assumptions and judgments are subject to factors
and uncertainties regarding their outcome. Therefore, actual results may
materially differ from these estimates.

                                       19
--------------------------------------------------------------------------------
  Table of Contents
Some of our significant accounting policies require us to make subjective or
complex judgments or estimates. An accounting estimate is considered to be
critical if it meets both of the following criteria: (1) the estimate requires
assumptions about matters that are highly uncertain at the time the accounting
estimate is made, and (2) different estimates that reasonably could have been
used, or changes in the estimate that are reasonably likely to occur from period
to period, would have a material impact on the presentation of our financial
condition, results of operations, or cash flows.

Our critical accounting policies are identified in Item 7 of Part II of our Annual Report on Form 10-K for the fiscal year ended June 30, 2021 under the heading "Critical Accounting Policies and Significant Judgments and Estimates."

--------------------------------------------------------------------------------

Table of Contents Comparison of Three Months Ended September 30, 2021 with Three Months Ended September 30, 2020



Net revenues. Net revenues decreased by $2.1 million, or 3.6%, from $60.5
million for the three months ended September 30, 2020 to $58.4 million for the
three months ended September 30, 2021. U.S. peripheral revenues decreased $4.1
million, or 9.4%, while U.S. coronary revenues increased $265,000, or 1.7%. The
impact of the Delta variant of the SARS-CoV-2 virus had an impact on both
therapies, especially within the hospital setting. Contributing factors to the
decreased case volumes from the Delta variant were disruptions of referral
patterns, deferrals of elective procedures, staffing shortages and heightened
summer seasonality in the quarter ended September 30, 2021. We have also been
affected by an increasingly competitive environment, although to a lesser extent
than COVID-19. Increased revenue from new product launches and increased
customer adoption of interventional support products partially offset the
revenue declines from decreased case volumes in the peripheral franchise, while
these factors fully offset decreased case volumes in the coronary franchise.
International revenue was $3.3 million for the three months ended September 30,
2021, compared with international revenue of $1.7 million for the three months
ended September 30, 2020. Although international sales were also impacted by the
ongoing COVID-19 pandemic, increases in international sales were driven by
Coronary OAS sales in Europe, a stronger recovery in Japan and the Asia Pacific
region, and the commencement of sales into Canada. In the second quarter of
fiscal 2022, we expect our revenue will continue to be impacted by the COVID-19
pandemic's effect on case volumes, but to a lesser degree than the three months
ended September 30, 2021. Longer-term we expect revenue growth to return to
recently observed normal levels driven by increasing the number of physicians
using the devices; increasing the usage per physician; introducing new and
improved products; generating additional clinical data; and continuing expansion
into new geographies, partially offset by potential decreases in average selling
prices.

Cost of Goods Sold. Cost of goods sold was $14.3 million for the three months
ended September 30, 2021, an increase of 13.9% from $12.6 million for the three
months ended September 30, 2020. These amounts represent the cost of materials,
labor and overhead for single-use catheters, guide wires, pumps, and other
ancillary products. Gross margin decreased to 75.5% for the three months ended
September 30, 2021 from 79.2% for the three months ended September 30, 2020,
primarily due to increased sales of lower margin products. We expect that gross
margin in the second quarter of fiscal 2022 will be similar to the gross margin
in the three months ended September 30, 2021 due to a continued shift of sales
mix into interventional support products and international markets in addition
to declining average selling prices. Quarterly margin fluctuations could also
occur based on production volumes, timing of new product introductions, sales
mix, pricing changes, or other unanticipated circumstances.

Selling, General and Administrative Expenses. Our selling, general and
administrative expenses were $41.9 million for the three months ended
September 30, 2021, an increase of 3.9% from $40.3 million for the three months
ended September 30, 2020. SG&A expense increases were led by costs associated
with new product introductions and the resumption of travel-related expenditures
due to increased live meetings and tradeshows, in addition to annual salary
increases for our employees. These increases were partially offset by reduced
commission expenses due to lower sales in the current year period. Selling,
general and administrative expenses for the three months ended September 30,
2021 and 2020 include $4.5 million and $3.9 million, respectively, for
stock-based compensation. We expect our selling, general and administrative
expenses for the second quarter of fiscal 2022 to be greater than amounts
incurred for the three months ended September 30, 2021.

Research and Development Expenses. Research and development expenses increased
by 10.7%, from $9.1 million for the three months ended September 30, 2020 to
$10.0 million for the three months ended September 30, 2021. Research and
development expenses relate to specific projects to develop new products or
expand into new markets, such as the development of new versions of the
Peripheral and Coronary OAS, shaft designs and crown designs, and expanded
product offerings, and to clinical trials. The increase was due to increased
costs on the ECLIPSE clinical trial resulting from an increase in enrollments
compared to the paused enrollment status in the prior year period. We expect a
similar level of research and development expense in the second quarter of
fiscal 2022 to what we incurred during the three months ended September 30,
2021. Quarterly fluctuations could occur based on the number of projects and
studies, the progress of such projects and studies, the rate of study
enrollment, acquisitions of IPR&D and possible charges in connection with those
acquisitions, and the timing of expenditures.

LIQUIDITY AND CAPITAL RESOURCES

We had cash, cash equivalents and highly liquid marketable securities of $187.6
million and $207.0 million at September 30, 2021 and June 30, 2021,
respectively. As of September 30, 2021, we had an accumulated deficit of $395.0
million. We have historically funded our operating losses primarily from the
issuance of common and preferred stock, convertible promissory notes, and debt.

A summary of our cash flow activities (in thousands) is as follows:

Changes in Liquidity

Operating Activities

Net cash used in operating activities was $10.8 million for the three months
ended September 30, 2021, primarily due to the net loss of $8.6 million, and
$9.5 million relating to changes in working capital as a result of the payout of
annual bonuses and commissions, partially offset by non-cash expenditures for
the three months ended September 30, 2021.

Net cash used in operating activities was $2.2 million for the three months
ended September 30, 2020, primarily due to the net loss of $2.1 million, an
increase in receivables as we experienced a recovery in our sales volumes, and
increased uses of cash to build inventory and diversify our products, as well as
for payouts of previously accrued bonuses and commissions. The amount of cash
used was partially offset by increased accounts payable due to timing of
activity and payments, and non-cash expenditures for the three months ended
September 30, 2020.

Investing Activities



Net cash provided by investing activities was $11.6 million for the three months
ended September 30, 2021, as maturities and sales of marketable securities
exceeded marketable security purchases in the three months ended September 30,
2021. These amounts were partially offset by a product acquisition of peripheral
microcatheters and capital expenditures as we continue to grow our business.

Net cash provided by investing activities was $87.2 million for the three months
ended September 30, 2020, primarily due to investing cash from our June 2020
equity offering into marketable securities. We also deployed cash into strategic
investments and capital expenditures as we continue to grow our business. These
uses of cash were partially offset by maturities and sales of marketable
securities.

Financing Activities



Net cash used in financing activities was $5.0 million and $3.4 million for the
three months ended September 30, 2021 and 2020, respectively, primarily due to
the payment of payroll taxes on the employee vesting of stock awards.

Our future liquidity and capital requirements will be influenced by numerous
factors, including the extent and duration of future operating losses, the level
and timing of future sales and expenditures, the results and scope of ongoing
research and product development programs, working capital required to support
our business operations, the receipt of and time required to obtain regulatory
clearances and approvals, our sales and marketing programs, the continuing
acceptance of our products in the marketplace, competing technologies, market
and regulatory developments, ongoing facility requirements, potential strategic
transactions (including the potential acquisition of, or investments in,
businesses, technologies and products), international expansion, the existence,
defense and resolution of legal proceedings, and the severity and duration of
the COVID-19 pandemic. As discussed in the "Overview" above, the total impact of
disruptions from COVID-19 has had a material impact on our financial condition
and results of operations, but once the pandemic subsides, we expect our U.S.
business to return to a
                                       22

  Table of Contents
more normalized pre-pandemic level of operations and activity. We will continue
to closely monitor our liquidity and capital resources through the disruption
caused by COVID-19 and will continue to evaluate our financial position to
assess additional spending reductions and our liquidity needs. As of
September 30, 2021, we believe our current cash, cash equivalents and marketable
securities will be sufficient to fund working capital requirements, including
open purchase commitments, capital expenditures and operations for the
foreseeable future, including at least the next twelve months, as well as to
fund payments under our lease agreements, payments under development agreements
and future payments relating to our asset acquisition of the WIRION embolic
protection system. If needed, we have the ability to borrow under our senior,
secured revolving credit facility. We intend to retain any future earnings to
support operations and to finance the growth and development of our business. We
do not anticipate paying any dividends in the foreseeable future.

Facility Sale and Lease



On December 29, 2016, we entered into a Purchase and Sale Agreement, as
subsequently amended (collectively, the "Sale Agreement"), with Krishna
Holdings, LLC ("Krishna"), providing for the sale to Krishna of our headquarters
facility in St. Paul, Minnesota (the "Facility") for a cash purchase price of
$21.5 million. On March 30, 2017, the sale of the Facility under the Sale
Agreement closed. We received proceeds of approximately $20.9 million ($21.5
million less $556,000 of transaction expenses). In connection with the closing
of the facility sale, we entered into a Lease Agreement (the "Lease Agreement")
with Krishna Holdings, LLC, Apex Holdings, LLC, Kashi Associates, LLC, Keva
Holdings, LLC, S&V Ventures, LLC, Polo Group LLC, SPAV Holdings LLC, Star
Associates LLC, and The Global Villa, LLC. The Lease Agreement has an initial
term of fifteen years, with four consecutive renewal options of five years each,
with a base annual rent in the first year of $1.6 million and annual escalations
of 3%. See Note 6 to our Consolidated Financial Statements included in Item 1 of
Part I of this Quarterly Report on Form 10-Q for additional discussion.

Revolving Credit Facility



In March 2017, we entered into a Loan and Security Agreement (the "Loan
Agreement") with Silicon Valley Bank ("SVB"). In March 2020, we entered into the
First Amendment to the Loan Agreement (the "Amendment"). The Amendment extended
the maturity date of the Loan Agreement by two years, to March 31, 2022, and
increased the maximum amount available under the senior, secured revolving
credit facility (the "Revolver") to $50.0 million (the "Maximum Dollar Amount").

Advances under the Revolver may be made from time to time up to the Maximum
Dollar Amount, subject to certain borrowing limitations. The Revolver bears
interest at a floating per annum rate equal to the Wall Street Journal prime
rate, less 0.75%. Interest on borrowings is due monthly and the principal
balance is due at maturity. Upon the Revolver's maturity, any outstanding
principal balance, unpaid accrued interest, and all other obligations under the
Revolver will be due and payable. We will incur a fee equal to 3% of the Maximum
Dollar Amount upon termination of the Loan Agreement, as amended by the
Amendment (the "Amended Loan Agreement"), or the Revolver for any reason prior
to the date that is fifteen days prior to the maturity date, unless refinanced
with SVB.

Our obligations under the Amended Loan Agreement are secured by certain of our
assets, including, among other things, accounts receivable, deposit accounts,
inventory, equipment, general intangibles and records pertaining to the
foregoing. The collateral does not include our intellectual property, but we
agreed not to encumber our intellectual property without the consent of SVB. The
Amended Loan Agreement contains customary covenants limiting our ability to,
among other things, incur debt or liens, make certain investments and loans,
enter into transactions with affiliates, undergo certain fundamental changes,
dispose of assets, or change the nature of our business. In addition, the
Amended Loan Agreement contains financial covenants requiring us to maintain, at
all times when any amounts are outstanding under the Revolver, either (i)
minimum unrestricted cash at SVB and unused availability on the Revolver of at
least $10.0 million or (ii) minimum trailing three-month Adjusted EBITDA (as
defined in the Amended Loan Agreement) of $1.0 million. If we do not comply with
the various covenants under the Amended Loan Agreement or an event of default
under the Amended Loan Agreement occurs, such as a material adverse change, the
interest rate on outstanding amounts will increase by 5% and SVB may, subject to
various customary cure rights and the other terms and conditions of the Amended
Loan Agreement, decline to provide additional advances under the Revolver,
require the immediate payment of all amounts outstanding under the Revolver, and
foreclose on all collateral.

We are required to pay a fee equal to 0.15% per annum on the unused portion of
the Revolver, payable quarterly in arrears. We are not obligated to draw any
funds under the Revolver and have not done so under the Revolver since entering
into the Loan Agreement. No amounts were outstanding as of September 30, 2021
and we currently do not have plans to borrow under the Amended Loan Agreement.

NON-GAAP FINANCIAL INFORMATION

To supplement our condensed consolidated financial statements prepared in
accordance with GAAP, our management uses a non-GAAP financial measure referred
to as "Adjusted EBITDA." Reconciliations of this non-GAAP measure to the most
comparable U.S. GAAP measure for the respective periods can be found in the
following table. In addition, an explanation of the manner in which our
management uses this measure to conduct and evaluate our business, the economic
substance behind our management's decision to use this measure, the substantive
reasons why our management believes that this measure provides useful
information to investors, the material limitations associated with the use of
this measure and the manner in which our management compensates for those
limitations is included following the reconciliation table.

Adjusted EBITDA decreased for the three months ended September 30, 2021 as compared to the three months ended September 30, 2020 primarily due to a greater loss from operations in the current year.

Use and Economic Substance of Non-GAAP Financial Measures Used and Usefulness of Such Non-GAAP Financial Measures to Investors



We use Adjusted EBITDA as a supplemental measure of performance and believe 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, stock-based compensation and IPR&D charges. Our
management uses Adjusted EBITDA to analyze the underlying trends in our
business, assess the performance of our core operations, establish operational
goals and forecasts that are used to allocate resources and evaluate our
performance period over period and in relation to our competitors' operating
results. Additionally, our management is partially evaluated on the basis of
Adjusted EBITDA when determining achievement of their incentive compensation
performance targets. Management does not use this Adjusted EBITDA measure as a
liquidity measure or in the calculation of our financial covenants under the
revolving credit facility with Silicon Valley Bank.

We believe that presenting Adjusted EBITDA provides investors greater
transparency to the information used by our management for its financial and
operational decision-making and allows investors to see our results "through the
eyes" of management. We also believe that providing this information better
enables our investors to understand our operating performance and evaluate the
methodology used by our 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. We exclude stock-based compensation expense from our
non-GAAP financial measures primarily because such expense, while constituting
an ongoing and recurring expense, is not an expense that requires cash
settlement.

•Depreciation and amortization expense. We exclude depreciation and amortization
expense from our 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 our management to assess the core
profitability of our business operations.

•IPR&D charges incurred in connection with asset acquisitions. We exclude charges incurred in connection with acquired IPR&D in asset acquisitions from our non-GAAP financial measures given the one-time nature of such


                                       24

expense, which is not used by our management to assess the core profitability of
our business operations. There may be fiscal periods where we do not incur these
charges and therefore they may not be included within the table above.

Our management also believes that excluding these above items from our non-GAAP results is useful to investors to understand our operational performance, liquidity and ability to make additional investments in our company.

Material Limitations Associated with the Use of Non-GAAP Financial Measures and Manner in which We Compensate for these Limitations



Non-GAAP financial measures have limitations as analytical tools and should not
be considered in isolation or as a substitute for our financial results prepared
in accordance with GAAP. Some of the limitations associated with our use of
these non-GAAP financial measures are:

•Items such as stock-based compensation do not directly affect our cash flow
position; however, such items reflect economic costs to us and are not reflected
in our 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 we do, limiting the usefulness of those measures for comparative purposes.



•Our management exercises judgment in determining which types of charges or
other items should be excluded from the non-GAAP financial measures we use. We
compensate for these limitations by relying primarily upon our GAAP results and
using non-GAAP financial measures only supplementally.

We provide detailed reconciliations of each non-GAAP measure to its most directly comparable GAAP measure. We encourage investors to review these reconciliations. We qualify our use of non-GAAP financial measures with cautionary statements as set forth above.

INFLATION

We do not believe that inflation had a material impact on our business and operating results during the periods presented.

OFF-BALANCE SHEET ARRANGEMENTS

Since inception, we have not engaged in any off-balance sheet activities as defined in Item 303(a)(4) of Regulation S-K.
