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 these
difficult disease states. 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.

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 three months ending June 30 usually
representing the highest volume of cases and, therefore, the highest amount of
revenue generated by us during the course of the fiscal year.

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, 2022. 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 six months ended December 31, 2022 represented approximately
63% 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.

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 six months ended December 31, 2022 represented
approximately 29% of revenue.

International

We serve a growing patient population globally through an expanding distribution
and sales network. Sales of our approved products in Japan have been made
through our exclusive Japan distributor, Medikit Co., Ltd. ("Medikit"). On
December 13, 2022, we entered into a distribution agreement with Otsuka Medical
Devices Co., Ltd. Effective February 1, 2023, upon the expiration of our
distribution agreement with Medikit, Otsuka became our exclusive Japan
distributor. Sales of our products in the rest of the world, which primarily
includes certain countries in Southeast Asia, Europe, Latin America, the Middle
East and Canada, are made through a network of distributors and sales agents.
International sales during the six months ended December 31, 2022 represented
approximately 8% 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 and sales agents
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 in fiscal 2022, such as the 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; and
decreased employee productivity. Some of these disruptions continued into the
first and second quarters of fiscal 2023, although to a lesser extent than we
experienced in the first and second quarters of fiscal 2022.

Throughout the pandemic, we have operated our manufacturing facilities and
continued to ship product. Most of our office-based employees have telecommuted,
and our field employees have continued to support cases in clinical settings
where they are able to have access. We took and continue to take 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.

Throughout the COVID-19 pandemic, we have observed the impact from the spread of
some variants, and the fluctuations in hospitalizations resulting from these
variants. For example, there were significant disruptions in procedures that
occurred in the first quarter of fiscal 2022 due to the Delta variant outbreak
and in the second and third quarters of fiscal 2022 due to the Omicron variant
outbreak. 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. We continue to monitor the spread of variants and track hospitalizations
resulting from variants of the SARS-CoV-2 virus.

The Abbott Transaction



On February 8, 2023, we entered into an Agreement and Plan of Merger (the
"Abbott Merger Agreement") with Abbott Laboratories, an Illinois corporation
("Abbott"), and Cobra Acquisition Co., a Delaware corporation and a direct,
wholly-owned subsidiary of Abbott ("Merger Sub"). The Abbott Merger Agreement
provides that, upon the terms and subject to the conditions set forth in such
agreement, Merger Sub will merge with and into us, and we will continue as the
surviving corporation and as a wholly-owned subsidiary of Abbott (the "Abbott
Transaction"). At the effective time of the Abbott Transaction, each share of
our common stock issued and outstanding immediately prior to the effective time,
subject to certain exceptions set forth in the Abbott Merger Agreement, will
automatically convert into and be exchangeable for the right to receive $20.00
per share in cash, without interest.

The boards of directors of both the Company and Abbott have unanimously approved
the Abbott Merger Agreement and the Abbott Transaction. Our board of directors
unanimously recommended that our stockholders vote to adopt the Abbott Merger
Agreement and approve the transactions contemplated thereby, including the
Abbott Transaction, and directed that the adoption of the Abbott Merger
Agreement be submitted to a vote of our stockholders.
                                       20

Table of Contents



The closing of the Abbott Transaction is subject to the affirmative vote of the
holders of a majority of our outstanding shares of common stock to adopt the
Abbott Merger Agreement, the expiration or termination of any waiting period
(and extensions thereof) under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, as amended, and various other closing conditions.

The Abbott Merger Agreement includes certain termination provisions for both us
and Abbott and provides that (i) in connection with the termination of the
Abbott Merger Agreement under certain specified circumstances related to a
change in the recommendation of the Company, the entry into an agreement for a
superior proposal or the breach of certain of our covenants under the Abbott
Merger Agreement, we may be required to pay Abbott a termination fee of
$26,500,000, and (ii) in connection with the termination of the Abbott Merger
Agreement after November 8, 2023 (or as such date might be extended under the
Abbott Merger Agreement) under certain specified circumstances related to
antitrust laws or due to the consummation of the Abbott Transaction being
permanently enjoined under antitrust laws, Abbott may be required to pay us a
termination fee of $26,500,000.

Additional information about the Abbott Merger Agreement and the Abbott Transaction will be set forth in the Company's preliminary and definitive proxy statements relating to the transaction that will be filed with the SEC.

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.

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, 2022 under the heading "Critical Accounting Policies and Significant Judgments and Estimates."

Table of Contents Comparison of Three Months Ended December 31, 2022 with Three Months Ended December 31, 2021



Net revenues. Net revenues increased by $2.3 million, or 3.9%, from $59.1
million for the three months ended December 31, 2021 to $61.5 million for the
three months ended December 31, 2022. U.S. peripheral revenues decreased $0.6
million, or 1.6%, while U.S. coronary revenues increased $1.5 million, or 8.8%.
Both therapies continue to be adversely affected by labor shortages and turnover
in the health care workforce. We have also been adversely affected by an
increasingly competitive environment and reimbursement pressures in the
office-based lab setting. Increased revenue from increased customer adoption of
interventional support products offset the revenue declines from decreased case
volumes, competitive pressures, and reimbursement pressures in the peripheral
and coronary franchises. International revenue was $5.1 million for the three
months ended December 31, 2022, compared with international revenue of $3.7
million for the three months ended December 31, 2021. Increases in international
sales were driven by increased adoption in Europe and Canada, and the
commencement of sales into other territories, as well as an increase in deferred
revenue recognized. In the third quarter of fiscal 2023, we expect to continue
growing revenue, driven by increasing the number of physicians using the devices
we sell; increasing the usage per physician; the use of new and improved
products, such as the Scoreflex NC scoring balloon, JADE balloons, ViperCross
Microcatheters, and the 2.00 Max Crown for Peripheral OAS; and continuing
expansion into new geographies, partially offset by potential decreases in
average selling prices and foreign currency exchange impacts. However, ongoing
factors such as staffing and supply shortages and competitive and reimbursement
pressures may continue to have an adverse impact.

Cost of Goods Sold. Cost of goods sold was $18.5 million for the three months
ended December 31, 2022, an increase of 2.1% from $18.1 million for the three
months ended December 31, 2021. These amounts represent the cost of materials,
labor and overhead for single-use catheters, guide wires, pumps, and other
ancillary products. Gross margin increased to 70.0% for the three months ended
December 31, 2022 from 69.4% for the three months ended December 31, 2021. The
increase in gross margin was primarily due to a $2.8 million reserve in the
three months ended December 31, 2021 related to the voluntary recall of the
WIRION device. Excluding this item, gross margin decreased primarily due to
increased sales of lower margin products, as well as increased inflationary
costs and freight costs. We expect that gross margin in the third quarter of
fiscal 2023 will be similar to the three months ended December 31, 2022 due to
an expected increase in device sales offset by the continued shift of sales mix
into interventional support products and international markets in addition to
declining average selling prices, which will also impact gross margins.
Quarterly margin fluctuations could also occur based on production volumes,
timing of new product introductions, sales mix, pricing changes, the impact of
inflation or other unanticipated circumstances.

Selling, General and Administrative Expenses. Our selling, general and
administrative expenses were $41.6 million for the three months ended
December 31, 2022, an increase of 3.1% from $40.4 million for the three months
ended December 31, 2021. Selling, general and administrative expense increases
were led by costs associated with incentive compensation expense, travel-related
expenditures and legal expenditures. Selling, general and administrative
expenses for the three months ended December 31, 2022 and 2021 include $3.0
million and $3.6 million, respectively, for stock-based compensation. We expect
our selling, general and administrative expenses for the third quarter of fiscal
2023 to be higher than amounts incurred for the three months ended December 31,
2022. Quarterly fluctuations could occur based on the level of net revenue,
which could be materially impacted by the factors noted above, as well as
inflation.

Research and Development Expenses. Research and development expenses increased
by 7.4%, from $8.9 million for the three months ended December 31, 2021 to $9.5
million for the three months ended December 31, 2022. 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, including
our percutaneous ventricular assist device, and to clinical trials. The increase
was primarily due to increased costs on the ECLIPSE clinical trial, initiation
of the Japan Kaizen clinical study and timing of costs associated with the
development activities of our percutaneous ventricular assist device. We expect
an increase in research and development expense in the third quarter of fiscal
2023 from what we incurred during the three months ended December 31, 2022.
Quarterly fluctuations could occur based on the number of projects and studies,
the progress of such projects and studies, the rate of study enrollment, the
impact of inflation, acquisitions of in process research and development and
possible charges in connection with those acquisitions, and the timing of
expenditures.

Comparison of Six Months Ended December 31, 2022 with Six Months Ended December
31, 2021

Net revenues. Net revenues increased by $3.6 million, or 3.1%, from $117.5
million for the six months ended December 31, 2021 to $121.1 million for the six
months ended December 31, 2022. U.S. peripheral revenues decreased $0.8 million,
or 1.1% and U.S. coronary revenues increased $1.7 million, or 5.1%. Both
therapies continue to be adversely affected by labor shortages and turnover in
the health care workforce. We have also been adversely affected by an
increasingly competitive environment and reimbursement pressures in the
office-based lab setting. Increased revenue from increased customer adoption of
interventional support products offset the revenue declines from decreased case
volumes, competitive pressures, and reimbursement pressures in the peripheral
and coronary franchises. International revenue was $9.8 million for the six
months ended December 31, 2022, compared with international revenue of $7.0
million for the six months ended December 31, 2021. Increases in international
sales were driven by increased adoption in Europe and Canada, and the
commencement of sales into other territories, as well as an increase in deferred
revenue recognized.

Cost of Goods Sold. Cost of goods sold was $35.2 million for the six months
ended December 31, 2022, an increase of 8.6% from $32.4 million for the six
months ended December 31, 2021. 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 71.0% for the six months ended
December 31, 2022 from 72.4% for the six months ended December 31, 2021.
Excluding the $2.8 million reserve in the six months ended December 31, 2021
related to the voluntary recall of the WIRION device, the increase in cost of
goods sold and decrease in gross margin were primarily due to increased sales of
lower margin products, as well as increased inflationary costs and freight
costs.

Selling, General and Administrative Expenses. Our selling, general and
administrative expenses were $86.1 million for the six months ended December 31,
2022, an increase of 4.7% from $82.3 million for the six months ended
December 31, 2021. Selling, general and administrative expense increases were
led by costs associated with incentive compensation expense and travel-related
expenditures. These increases were partially offset by lower stock compensation.
Selling, general and administrative expenses for the six months
ended December 31, 2022 and 2021 include $6.8 million and $8.1 million,
respectively, for stock-based compensation.

Research and Development Expenses. Research and development expenses decreased
by 1.6%, from $18.9 million for the six months ended December 31, 2021 to $18.6
million for the six months ended December 31, 2022. 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, including
our percutaneous ventricular assist device, and to clinical trials. The decrease
was primarily due to timing of international commercialization expenses and
project spend.

Operating Activities

Net cash used in operating activities was $17.2 million for the six months ended
December 31, 2022, primarily due to the net loss of $18.5 million, and $8.5
million relating to changes in working capital as a result of the payout of
annual bonuses and commissions, increased uses of cash to build inventory as we
diversify our product offerings, partially offset by non-cash expenditures for
the six months ended December 31, 2022.

Net cash used in operating activities was $12.3 million for the six months ended
December 31, 2021, primarily due to the net loss of $17.6 million, and $8.0
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 six months ended December 31, 2021.

Investing Activities



Net cash provided by investing activities was $10.5 million for the six months
ended December 31, 2022, as maturities and sales of marketable securities
exceeded marketable security purchases. These amounts were partially offset by
additional payments relating to strategic investments and capital expenditures
as we continue to grow our business.

Net cash provided by investing activities was $11.1 million for the six months
ended December 31, 2021, as maturities and sales of marketable securities
exceeded marketable security purchases during this period. These amounts were
partially offset by a product acquisition of peripheral microcatheters,
additional payments relating to strategic investments and capital expenditures
as we continue to grow our business.

Financing Activities



Net cash provided by financing activities was $0.1 million for the six months
ended December 31, 2022, primarily due to proceeds from employee stock
purchases, partially offset by payment of payroll taxes on the employee vesting
of stock awards.

Net cash used in financing activities was $4.0 million for the six months ended
December 31, 2021, primarily due to the payment of payroll taxes on the employee
vesting of stock awards, partially offset by proceeds from employee stock
purchases.

Our future liquidity and capital requirements will be influenced by numerous
factors, including whether we timely consummate the Abbott Transaction, 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 as the
pandemic subsides, we expect our U.S. business to improve. 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
December 31, 2022, 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 funding commitments under loan agreements. If needed, we have the ability to
borrow under our senior, secured revolving credit facility, which we intend to
extend. We will also consider other options for potential future financings to
fund our longer-term objectives. 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 5 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").
In March 2022, the Company entered into the Second Amendment to the Loan
Agreement (the "Second Amendment"). The Second Amendment extended the maturity
date of the Loan Agreement by one year, to March 31, 2023. We intend to seek an
additional extension of the Loan Agreement.

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 1.5% of the
Maximum Dollar Amount upon termination of the Loan Agreement, as amended by the
Second 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 December 31, 2022.

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.

                                         Three Months Ended             Six Months Ended

Add: Stock-based compensation             3,547         4,240          7,985          9,912

Adjusted EBITDA decreased for the three and six months ended December 31, 2022
as compared to the three and six months ended December 31, 2021 primarily due to
a greater loss from operations and lower stock compensation expense 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, and stock-based compensation. 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
                                       27

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

Table of Contents expenses that require cash settlement and are not used by our management to assess the core profitability of our business operations.

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.
