Overview



We are a global ear, nose and throat ("ENT") medical technology leader dedicated
to transforming patient care. Our U.S. Food and Drug Administration ("FDA")
approved steroid releasing products are designed to provide mechanical spacing
and deliver targeted therapy (mometasone furoate) to the site of disease. These
products include our PROPEL® family of products (PROPEL®, PROPEL® Mini and
PROPEL® Contour) and the SINUVA® (mometasone furoate) Sinus Implant. The PROPEL
family of products are used in adult patients to reduce inflammation and
maintain patency following sinus surgery primarily in hospitals and ambulatory
surgery centers ("ASC") and has increasing applications in the physician office
setting of care in conjunction with balloon dilation and following post-surgical
debridement. SINUVA is a physician administered drug, designed to be used in the
physician office setting of care to treat adult patients who have had ethmoid
sinus surgery yet suffer from recurrent sinus obstruction due to polyps. The
PROPEL family of products are combination products regulated as devices approved
under a Premarket Approval ("PMA") and SINUVA is a combination product regulated
as a drug that was approved under a New Drug Application ("NDA"). The PROPEL
family of products have also received CE Markings, permitting them to be
marketed in the European Economic Area.

In October 2020, we acquired Fiagon AG Medical Technologies ("Fiagon"), a global
leader of electromagnetic surgical navigation solutions with an expansive
portfolio of ENT product offerings, including the VenSure sinus dilation
platform ("VenSure") and CUBE Navigation System ("CUBE"), and instruments that
complement our PROPEL and SINUVA sinus implants across all settings of care and
extend our geographic reach. The VenSure products received 510(k) clearance in
August 2020 and the latest version of the CUBE Navigation System received 510(k)
clearance in July 2021. In addition, some of the Fiagon products are registered
in other countries including in Asia Pacific and South America.

While our primary commercial focus is the U.S., we are also expanding the global
reach of our products. Our commercialization strategy will consider several
factors including regulatory requirements, reimbursement coverage for our
products, and key opinion leader support. For the PROPEL family of products, our
initial focus is on Germany and the United Kingdom, where we are working to
build our capabilities and develop the market. Going forward, we will continue
to assess our capability to penetrate additional markets in Europe, Asia Pacific
and Japan.

Our PROPEL family of steroid releasing implants are clinically proven to improve
outcomes for chronic rhinosinusitis ("CRS") patients following sinus surgery.
PROPEL implants mechanically prop open the sinuses and release mometasone
furoate, an advanced corticosteroid with anti-inflammatory properties, directly
into the sinus lining, and then dissolve over time. PROPEL's safety and
effectiveness is supported by Level 1a clinical evidence from multiple clinical
trials, which demonstrates that PROPEL implants reduce inflammation and scarring
after surgery, thereby reducing the need for postoperative oral steroids and
repeat surgical interventions. Approximately 456,000 patients have been treated
with PROPEL products through the end of 2021. Our primary PROPEL® products are
as follows:

•PROPEL, a self-expanding implant designed to conform to and hold open the
surgically enlarged sinus while gradually releasing an anti-inflammatory steroid
over a period of approximately 30 days and is absorbed into the body over a
period of approximately six weeks.

•PROPEL Mini, a smaller version of PROPEL which is approved for use in both the
ethmoid and frontal sinuses. PROPEL Mini is used preferentially by physicians
compared with PROPEL when treating smaller anatomies or following less extensive
procedures.

•PROPEL Contour, designed to facilitate treatment of the frontal and maxillary
sinus ostia, or openings, of the dependent sinuses in procedures performed in
both the operating room and in the physician office setting of care. PROPEL
Contour's lower profile, hourglass shape and malleable delivery system are
designed for use in the narrow and difficult to access sinus ostia. PROPEL
Contour is approved for use in the frontal and maxillary sinus openings in the
U.S. and for use in the frontal sinus opening in the European Union ("EU").

The Straight Delivery System ("SDS") is an extension of the PROPEL family of
implants. It is specifically engineered for delivery of the PROPEL Mini Implant
into the ethmoid sinus. In February 2021, we announced the U.S. availability of
the SDS packaged with the PROPEL Mini after the combined packaging received FDA
approval.

SINUVA, when placed during a routine physician office visit, expands into the
sinus cavity and delivers an anti-inflammatory steroid directly to the site of
polyp disease for approximately 90 days. SINUVA is currently approved for use in
the U.S.

Our PROPEL family of products are used primarily in the operating room of a
hospital or ASC. These providers receive a facility fee for the sinus surgery
procedure which is intended to pay for supplies used in this procedure,
including the PROPEL family of products. SINUVA is a physician administered
drug, used almost exclusively in the physician office setting of care. VenSure
provides for dilation of the sinus ostia. The CUBE Navigation System supports
surgery and balloon dilation in all settings of care. The Centers for Medicare &
Medicaid Services ("CMS") approved SINUVA for transitional pass-through payment
status for reimbursement under the Hospital Outpatient Prospective Payment
System ("OPPS") and ASC Payment System. Pass-Through status lasts for three
years and allows us to place SINUVA in the ASC and hospital settings. We applied
to CMS in September 2020 and asked to separate the J7401 code from SINUVA and
PROPEL. In January 2021, CMS approved a revised coding application for our
PROPEL family of products and established a separate code for PROPEL, S1091
"Stent, non-coronary, temporary, with delivery system (propel)". CMS also made
updates to the current SINUVA J-code to J7402 "Mometasone furoate sinus implant,
(sinuva), 10 micrograms" and attached an average selling price ("ASP") to the
code. The new PROPEL and SINUVA codes took effect April 1, 2021. We are also
committed to expanding our market development efforts for PROPEL in the
physician office setting of care as well as market access outside of the U.S.

Our VenSure Navigable and Stand-alone balloon offerings are used to access and
treat the frontal, recess sphenoid sinus ostia, maxillary ostia/ethmoid
infundibula in adults using a trans-nasal approach. The VenSure Navigation
balloon is intended for use in conjunction with the CUBE navigation system
during sinus procedures when surgical navigation or image-guided surgery may be
necessary to locate and displace bone, or cartilaginous tissue surrounding the
drainage pathways of the frontal, maxillary, and sphenoid sinuses to facilitate
dilation of the sinus ostia.

Our CUBE Navigation System is an innovative virtual guidance platform for high
precision ENT and ENT related skull-base surgeries. The system's unique photo
registration technology, VirtuEye™, enhances the user's navigation experience
and improves pre-surgery efficiency. This novel 4D-imaging technology mitigates
common tactile tracing errors by collecting thousands of patient reference
points in one camera shot. The entire photo registration process can be achieved
in under 30 seconds without touching the patient.

We also continue to perform research and development activities and clinical
trials in order to expand our portfolio of products and improve our existing
products. In the second quarter of 2021, we initiated the EXPAND study to assess
the potential to improve frontal sinus ostia patency and other outcomes through
localized drug delivery following balloon dilation utilizing PROPEL Contour and
the VenSure balloon. In support of our focus on expanding our global reach, we
plan to make clinical and regulatory investments in PROPEL in Europe.


Debt Financings



On May 11, 2020, to finance our commercial activities as well as for general
corporate purposes, we entered into a Facility Agreement (the "Facility
Agreement") with Deerfield Partners, L.P. ("Deerfield"), as agent for itself and
the lenders, providing for the issuance and sale by us to Deerfield of $65.0
million of principal amount of 4.0% unsecured senior convertible notes (the
"Convertible Notes") upon the terms and conditions set forth in the Facility
Agreement. The $65.0 million principal amount of the Convertible Notes is not
payable until the maturity date of May 9, 2025, unless earlier converted or
redeemed. The Convertible Notes are convertible into shares of our common stock.

On July 22, 2021, we entered into an additional agreement with Deerfield,
providing for the issuance and sale by us to Deerfield of 7.5% senior secured
loans of an aggregate principal of up to $60.0 million (the "Deerfield Loans").
The Deerfield Loans will mature on July 22, 2026, unless earlier repaid or
accelerated. The agreement provides for the disbursement of the Deerfield Loans
in three tranches of $20.0 million, with the initial tranche disbursed on the
closing date of the transaction, the second tranche to be disbursed at our
option on the earlier of the date of any prepayment of the remaining Fiagon
acquisition payments and September 15, 2022, and the third tranche to be
disbursed at our option on the earlier of the date of any prepayment of the
remaining Fiagon acquisition payments and September 15, 2023. As of December 31,
2021 we had only borrowed the first $20.0 million under the Deerfield Loans.

On September 25, 2021, we entered into a financing arrangement with Medtronic
(the "Medtronic Financing"), providing for 5.0% unsecured subordinated loans of
an aggregate principal amount of up to $75.0 million to us upon the terms and
conditions of the Medtronic Financing. The Medtronic Financing will mature 180
days following the earlier of (x) the maturity date of the Deerfield Loans and
(y) the date on which the Deerfield Loans have been fully paid in cash and are
terminated, unless earlier repaid or accelerated. As of December 31, 2021,
borrowings on the Medtronic Financing had a net carrying amount of $30.0
million.

See Note 11. Long-Term Debt of Notes to our consolidated financial statements for a further description of these loan arrangements.

Pending Acquisition



On August 6, 2021, we entered into an Agreement and Plan of Merger (the "Merger
Agreement") with Medtronic, Inc., a Minnesota Corporation and wholly-owned
subsidiary of Medtronic public limited company ("Medtronic"), and Project Kraken
Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of
Medtronic ("Merger Sub"), providing for the merger of Merger Sub with and into
Intersect ENT (the "Merger"), with Intersect ENT surviving the Merger as a
wholly-owned subsidiary of Medtronic. On October 8, 2021, our stockholders
adopted the Merger Agreement at a special meeting of our stockholders.

Under the terms of the Merger Agreement, Medtronic will acquire all outstanding
shares of our common stock, including all vested and unvested awards, in
exchange for consideration of $28.25 per share in cash. Vested and unvested
stock options will be redeemed for the difference between $28.25 per option and
the respective exercise price. The Merger Agreement contains representations and
warranties customary for transactions of this type. The closing of the Merger is
subject to the satisfaction or waiver of a number of closing conditions,
including approval under the Hart-Scott-Rodino Antitrust Improvements Act of
1976. The Merger Agreement provides Medtronic and us with certain termination
rights and, under certain circumstances, may require that Medtronic or we pay a
termination fee.

In anticipation of the Merger, we have committed to a plan to divest of the
recently acquired Fiagon business, which we expect to be contingent on and
coterminous with the anticipated Merger. As of December 31, 2021, the assets and
liabilities of the Fiagon business have been presented as held for sale on our
consolidated balance sheets.

The Merger Agreement includes restrictions on the conduct of our business prior
to the completion of the Merger, generally requiring us to conduct our business
in the ordinary course, consistent with past practice, and restricting us from
taking certain specified actions absent Medtronic's prior written consent.
Accordingly, our ability to advance our business during the pendency of the
Merger is subject to these restrictions.

Impact of the COVID-19 Pandemic



Prior to the COVID-19 pandemic, our efforts to enhance commercial execution and
improve market access infrastructure were beginning to yield benefits as sales
until the end of February 2020 were consistent with our expectations. However,
sales declined towards the end of the first quarter of 2020 and throughout the
second quarter as the various COVID-19 restrictions were implemented and
remained in effect. We began to see meaningful change in the business
environment towards the end of May 2020 with increased procedure volumes as
select areas of the country eased restrictions on elective medical procedures.
This trend continued in June 2020 and throughout the remainder of 2020 as well
as throughout 2021 as we continued to see improvements in the elective procedure
market. Our business has been and will be impacted by patients' decisions to
undergo sinus surgeries and as ENT ASC and office procedure volumes begin to
recover. We continue to remain flexible in our approach to continuing our
operations in light of developing laws and restrictions surrounding
the COVID-19 pandemic. While the second half of 2020 and the full year of 2021
have provided an improving business environment, the COVID-19 pandemic may
continue to create severe disruptions and volatility in global capital markets
and increase economic uncertainty and instability. The impact of this on the
global economy has been and may continue to be severe and may impact our
operations and financial results.

Components of Our Results of Operations

Revenue



We have derived our revenue almost exclusively from the sales of our PROPEL
family of products, with limited sales of SINUVA beginning in March 2018, as
well as sales of CUBE and VenSure products beginning in the fourth quarter of
2020 with the acquisition of Fiagon. While our business has been and may
continue to be impacted by hospitals suspending elective surgical procedures and
reduced ENT office visits for an extended period of time, we anticipate
continued revenue growth in 2022 based on the increased elective procedure
volumes and enrollment trends towards the end of 2020 and throughout 2021. Once
the disruption from the COVID-19 pandemic subsides, we expect our revenue to
increase as we continue to expand our sales, marketing and reimbursement efforts
in order to increase usage of our products. We also expect revenue from our
PROPEL family of products to fluctuate from quarter to quarter due to seasonal
variations in the volume of sinus surgery procedures performed, which has been
impacted historically by factors including the status of patient healthcare
insurance plan deductibles and the seasonal nature of allergies which can impact
sinus-related symptoms. We recognize revenue from SINUVA net of estimated
product sales discounts, rebates, returns and other allowances as a reduction of
revenue in the same
                                       50

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

Table of Contents



period we recognize revenue. We will adjust these estimates if actual allowances
vary from our estimates, which would affect revenue in the period such variances
become known. In addition to standalone sales of CUBE and VenSure products, from
time to time, we enter into lease arrangements of CUBE navigation equipment with
certain qualified customers in connection with commitments to purchase VenSure
and other consumable products to accompany the use of the equipment. Leases have
terms that generally range from 24 to 48 months and are usually collateralized
by a security interest in the underlying assets. Lease arrangements transfer the
ownership or provide the customer with a right to purchase the equipment at the
end of the lease term.

We have derived our revenue predominantly from within the United States and no single customer accounted for more than 10% of our revenue during the years ended December 31, 2021, 2020 and 2019.

Cost of Sales and Gross Profit



We manufacture our PROPEL family of products and SINUVA in our facility in Menlo
Park, California. We manufacture CUBE navigation equipment and instruments in
Hennigsdorf, Germany, and procure VenSure sinus dilation balloons from a
third-party manufacturer located in the U.S. Cost of sales consists primarily of
manufacturing overhead costs, material costs, and direct labor. A significant
portion of our cost of sales currently consists of manufacturing overhead costs.
These overhead costs include compensation, including stock-based compensation
and other operating expenses associated with the cost of quality assurance,
material procurement, inventory control, facilities, information technology,
equipment and operations supervision and manufacturing and warehouse management.
Cost of sales also includes depreciation expense for production equipment,
amortization of intangible assets associated with acquired product technologies
and processes, maintenance of operational processes, and certain direct costs
such as shipping costs. Once the disruption from the COVID-19 pandemic subsides,
we expect cost of sales to increase in absolute dollars again primarily as, and
to the extent, our revenue grows, or we make additional improvements in our
manufacturing capabilities.

Our gross margin has been and will continue to be affected by a variety of
factors, including manufacturing costs, production and sales volume, product
mix, and average selling prices. Toward the end of the first quarter and
throughout the second quarter of 2020, manufacturing costs were negatively
impacted by the mandatory shelter-in-place order in effect in San Mateo County,
California, which prevented us from using our manufacturing facility, as well as
our decision to suspend production until the third quarter of 2020. Production
resumed during the third quarter of 2020, but below normal capacity, and was at
normal capacity thereafter. We charge idle facility costs to cost of goods sold
in the period incurred. Manufacturing cost will change as our production volume
and product mix changes. The per unit allocation of our manufacturing overhead
costs may increase and our gross margin may decline as, and to the extent,
production volume decreases.

Selling, General and Administrative Expenses



Selling, general and administrative, or SG&A, expenses consist primarily of
compensation for personnel, including stock-based compensation, related to
selling, marketing, finance, market access, reimbursement, business development,
legal and human resource functions as well as costs related to any post-market
studies. Additional SG&A expenses include commissions, training, travel
expenses, promotional activities, conferences, trade shows, professional
services fees, audit compliance expenses, insurance costs, amortization of
intangible assets associated with acquired customer and distributor
relationships, and general corporate expenses including allocated facilities and
information technology expenses.

Research and Development Expenses



Research and development, or R&D, expenses consist primarily of compensation for
personnel, including stock-based compensation, related to product development,
regulatory affairs, clinical and medical affairs, and allocated facilities and
information technology expenses. R&D expenses also may include expenses for
clinical studies related to clinical trial design, site reimbursement, data
management, travel expenses and the cost of manufacturing products for clinical
trials. Finally, R&D expenses also include expenses related to the development
of products and technologies such as consulting services and supplies.

Impairment on Assets Held for Sale



In anticipation of the Merger with Medtronic, we have committed to a plan to
divest of the recently acquired Fiagon business, and, as a result, have
presented the assets and liabilities of the Fiagon business as held for sale on
the consolidated balance sheets as of December 31, 2021. We recorded an
impairment charge of $67.8 million in the consolidated statements of operations
and comprehensive loss relating to goodwill, intangible assets, property
equipment, right-of-use assets, and inventory, representing the difference
between the carrying value of the assets and liabilities of the Fiagon business
and the fair value less selling costs as of December 31, 2021. We believe there
will be an additional loss of approximately $15.0 million to $20.0 million
contingent upon completing the sale of these assets.

Interest Expense



Interest expense consists primarily of the interest expense, accretion expense
of debt discounts, and amortization of debt issuance costs associated with debt
facilities, as well as imputed interest on the carrying value of deferred
acquisition related consideration.

Other Income (Expense), Net



Other income (expense), net consists primarily of interest earned on our cash
and cash equivalents, changes in the fair value of embedded derivatives,
transaction costs incurred outside the ordinary course of business related to
business combinations and our capital structure, impairment charges on held for
sale assets and liabilities, changes in the fair value of foreign currency
forward contracts, and the effects of foreign exchange, including on the
carrying value of our deferred acquisition related consideration.

Income Tax Benefit



Income tax benefit consists of an estimate of federal, state and foreign income
taxes based on enacted federal, state and foreign tax rates, as adjusted for
allowable credits, deductions, uncertain tax positions, changes in deferred tax
assets and liabilities and changes in tax law. Due to the level of historical
losses, we maintain a valuation allowance against U.S. federal, state, and
foreign deferred tax assets as we have concluded it is more likely than not that
these deferred tax assets will not be realized.

Revenue increased by $26.2 million, or 33%, to $106.7 million during the year
ended December 31, 2021, compared to $80.6 million during the year ended
December 31, 2020. The increase in revenue was due to a 23% increase in PROPEL
sales, 71% increase in SINUVA sales, and a significant increase in VenSure,
CUBE, and accessories sales. Higher PROPEL revenue resulted from a 22% increase
in unit sales, while average selling price remained consistent year-over-year.
The increase in unit sales for PROPEL was driven by a recovery in demand as
certain areas of the United States resumed elective procedures following easing
of COVID-19 pandemic restrictions. The increase in SINUVA sales was attributable
to a 59% increase in unit sales during the year ended December 31, 2021 as well
as an 8% increase in average selling price from the year ended December 31,
2020. The increase in unit sales for SINUVA during the year ended December 31,
2021 was due to a recovery in demand from the comparative period following
easing of COVID-19 pandemic restrictions, in addition to improvements in
reimbursement, continued adoption of the technology, and the ongoing shift of
procedures from hospitals and ASC to the physician office setting of care.
SINUVA sales also benefited from the expansion of our market access
infrastructure and the addition and expansion of our distributor relationships
during the prior year. Furthermore, revenue for the year ended December 31, 2021
included the first full year of sales from the CUBE navigation equipment and
instruments and VenSure sinus dilation balloons, while the prior year only
reflected one quarter of sales. The increase in sales was also attributable to
the formal launch of the CUBE 4D in July 2021 and a recovery in demand from the
comparative period following easing of the COVID-19 pandemic restrictions.

Based on current elective procedure volumes and enrollment trends, we expect
revenue growth in 2022. While we cannot predict the extent or duration of the
impact of the COVID-19 pandemic on our financial and operating results, we
believe that a recovery in procedures will continue, and that most patients will
return for treatment.

Cost of Sales and Gross Margin



Cost of sales decreased by $0.3 million, or 1%, to $30.0 million during the year
ended December 31, 2021, compared to $30.3 million during the year ended
December 31, 2020. The decrease in cost of sales in 2021 was primarily due to
the favorable impact of lower per unit manufacturing costs as a result of higher
production volumes due to a recovery in demand as elective surgeries resumed
following easing of COVID-19 pandemic restrictions and to build additional
safety stock. The decrease was offset by increased product sales resulting from
a recovery in demand as elective procedures resumed following easing of COVID-19
pandemic restrictions, amortization of intangible assets, production and
obsolescence related period costs, and project costs. Furthermore, during the
prior year, there was approximately $6.9 million of charges incurred related to
the impacts of COVID-19 which were not incurred during the current periods as
production volumes returned to normal capacity.

Gross margin for the year ended December 31, 2021, increased to 71.9%, compared
to 62.4% for the year December 31, 2020. The increase was attributable to the
favorable impact of lower per unit manufacturing costs, in addition to
approximately $6.9 million of charges related to the impacts of COVID-19
incurred in the prior period which were not incurred during the current period
as production volumes returned to normal capacity, as well as production and
obsolescence related period costs. The increase was offset in part by
amortization of intangible assets, production and obsolescence related period
costs, and project costs, collectively representing approximately 4% of revenue
for the year ended December 31, 2021.

With the expected increase in demand and our operation at full capacity, we do
not expect idle facility expense to be incurred in 2022. However, idle facility
expense could be incurred in future periods until the current health crisis
subsides. In addition, adequate safety stock levels were established by the end
of 2021 and consequently, we expect per unit manufacturing costs and gross
margins to normalize in future periods. We cannot reliably estimate the extent
to which the COVID-19 pandemic will impact the cost of sales and gross margin
for our products beyond the third quarter of 2022.

Selling, General and Administrative Expenses



SG&A expenses increased by $23.5 million, or 24%, to $122.1 million during the
year ended December 31, 2021, compared to $98.6 million during the year ended
December 31, 2020. The increase in SG&A expenses was primarily due to increased
commissions from increased sales, increases in headcount as compared to the
prior period as a result of increased sales and marketing and other activities
following the easing of COVID-19 pandemic related restrictions, the accrual of
retention bonuses, and incremental SG&A expense as a result of the acquisition
of Fiagon. Furthermore, the increase was due to $0.8 million of impairment
expense related to certain property, equipment, and intangible assets,
transaction costs associated with the proposed Merger, as well as costs
associated with the integration of Fiagon of $2.1 million and the divestiture of
Fiagon of $0.7 million, both of which consisted largely of professional fees.

We will continue to monitor our SG&A expenses in light of the uncertainties related to the COVID-19 pandemic; however, we will still continue to support our customers, physicians and patients.

Research and Development Expenses



R&D expenses increased by $8.6 million, or 44%, to $27.9 million during the year
ended December 31, 2021, compared to $19.4 million during the year ended
December 31, 2020. The increase in R&D expenses was primarily due to increased
headcount and related expenses as a result of the acquisition of Fiagon and
compared to the prior period as a result of cost reduction measures taken in the
prior year in response to the pandemic, the accrual of retention bonuses, as
well as professional fees pertaining to R&D projects in the current periods.

We will continue to monitor our R&D expenses in light of the uncertainty related
to the COVID-19 pandemic; however, we will continue to invest in our products
through R&D projects.

Impairment on Assets Held for Sale



In anticipation of the Merger with Medtronic, we have committed to a plan to
divest of the recently acquired Fiagon business. In recording the asset and
liabilities of the Fiagon business as held for sale, which requires presenting
them at fair value less selling costs as of December 31, 2021, we recorded an
impairment charge of $67.8 million. There were no similar charges in the prior
period. We believe there will be an additional loss of approximately $15.0
million to $20.0 million contingent upon completing the sale of these assets.

Interest Expense



Interest expense increased by $3.7 million to $6.4 million for the year ended
December 31, 2021, a significant increase compared to $2.8 million during the
year ended December 31, 2020. The increase was attributable to a full year of
interest expense on the Convertible Notes entered into during the second quarter
of 2020, a full year of imputed interest on deferred payments for the
acquisition of Fiagon, and interest incurred on the Deerfield Loans and
Medtronic Financing entered into in 2021.

Other Income (Expense), Net



Other expense, net, increased by $11.5 million to $(13.8) million during the
year ended December 31, 2021, a significant increase compared to $(2.3) million
during the year ended December 31, 2020. The increase in other expense, net, was
attributable to a $13.1 million increase in the fair value of an embedded
derivative liability associated with the Convertible Notes as the probability of
triggering events providing an elective increase in share issuance to the note
holder increased significantly due to the pending acquisition with Medtronic,
and the overall effects of foreign exchange remeasurement.


Income Tax Benefit



Income tax benefit increased by $1.3 million to $1.7 million for the year ended
December 31, 2021, a significant increase compared to $0.4 million for the year
ended December 31, 2020, which was attributable to the foreign tax impact
associated with the acquisition of Fiagon for a full year, compared to only one
quarter of benefit in the prior year. Future tax benefits are not expected due
to classification of the Fiagon business as held for sale as of December 31,
2021.

Comparison of Years Ended December 31, 2020 and 2019

Revenue

Revenue decreased by $28.6 million, or 26%, to $80.6 million during the year
ended December 31, 2020, compared to $109.1 million during the year ended
December 31, 2019. The decrease in revenue was due to a 29% decline in PROPEL
sales, partially offset by a 19% increase in SINUVA sales. Lower PROPEL revenue
resulted from a 31% decrease in unit sales, slightly offset by a 2% increase in
average selling price. The decrease in unit sales for PROPEL was driven by a
reduction in demand due to the impact of the COVID-19 pandemic. The increase in
SINUVA sales was attributable to a 13% increase in unit sales during the year
ended December 31, 2020 as well as a 5% increase in net revenue per unit from
the year ended December 31, 2019. The increase in unit sales for SINUVA during
the year ended December 31, 2020 was due to the improvement in reimbursement,
continued adoption of the technology, and the ongoing shift of procedures from
hospitals and ASC to the physician office setting of care. SINUVA sales also
benefited from the expansion of our Market Access infrastructure and the
addition and expansion of our distributor relationships during the year ended
December 31, 2020. Furthermore, revenue for the year ended December 31, 2020
also included $0.9 million from sales from the initiation of sales from the
acquired products, the CUBE navigation equipment and instruments and VenSure
sinus dilation balloons during the fourth quarter.

Cost of Sales and Gross Margin



Cost of sales increased by $8.5 million, or 39%, to $30.3 million during the
year ended December 31, 2020, compared to $21.8 million during the year ended
December 31, 2019. The increase in cost of sales in 2020 was primarily due to
the unfavorable impact of higher per unit manufacturing costs and $6.1 million
of idle facility costs partially offset by decreases in headcount as a result of
cost reduction measures initiated in the first quarter of 2020. Also the
increase was attributable to $0.8 million in additional charges related to
excess and obsolete inventory in response to the estimated impact of the
COVID-19 pandemic. The increases were partially offset by lower PROPEL unit
sales.

Gross margin for the year ended December 31, 2020, decreased to 62.4%, compared
to 80.1% for the year December 31, 2019. While the gross margin for our products
through the end of February 2020 was relatively consistent with our
expectations, the decrease in gross margin during the remainder of 2020 was
attributable to the unfavorable impact of higher per unit manufacturing costs as
well as the charges related to the impact of COVID-19. The amount of these
charges was approximately $6.9 million, representing an effect on our gross
margin of approximately 9 percentage-points for the year ended December 31,
2020. Our gross margin recovered in the second half of the year as we resumed
production and generated revenue.

Selling, General and Administrative Expenses



SG&A expenses decreased by $9.9 million, or 9%, to $98.6 million during the year
ended December 31, 2020, compared to $108.5 million during the year ended
December 31, 2019. The decrease in SG&A expenses was primarily due to decreases
in headcount and related expenses as a result of cost reduction measures
initiated in the first quarter of 2020, in addition to lower sales commissions
from reduced sales, partially offset by transaction costs associated with the
acquisition and integration of Fiagon of $4.0 million, which consisted largely
of professional fees.

Research and Development Expenses



R&D expenses decreased by $4.9 million, or 20%, to $19.4 million during the year
ended December 31, 2020, compared to $24.3 million during the year ended
December 31, 2019. The decrease in R&D expenses was primarily due to decreases
in headcount and related expenses as a result of cost reduction measures
initiated in the first quarter of 2020, as well as a delay of clinical efforts.
R&D projects include the development of the EXPAND study to be initiated in
2021, the PROPEL OPEN registry trial, and the ASCEND trial.

Interest Expense



Interest expense of $2.8 million for the year ended December 31, 2020 was
attributable to the Convertible Notes entered into during the second quarter of
2020 as well as imputed interest on deferred payments for the acquisition of
Fiagon. There were no similar expenses in the prior year.

Other Income (Expense), Net



Other income (expense), net, decreased by $4.7 million to $(2.3) million during
the year ended December 31, 2020, compared to $2.4 million during the year ended
December 31, 2019. The decrease in other income (expense), net was attributable
to a $1.2 million increase in fair value of our embedded derivative liability
associated with the Convertible Notes, a net foreign exchange loss of $1.6
million on the revaluation of the Fiagon purchase liability and respective
forward contracts, and the overall effects of foreign exchange remeasurement, as
well as significantly lower interest rates earned on investments.

Income Tax Benefit

Income tax benefit of $0.4 million for the year ended December 31, 2020 was attributable to the foreign tax impact associated with the acquisition of Fiagon. There were no similar benefits in the prior year.

Liquidity and Capital Resources

Overview



As of December 31, 2021, we had cash, cash equivalents, short-term investments,
and restricted cash of $78.9 million, compared to cash, cash equivalents,
short-term investments, and restricted cash of $105.5 million as of December 31,
2020.

Net Cash Used in Operating Activities



During the year ended December 31, 2021, net cash used in operating activities
was $59.5 million, consisting primarily of a net loss of $159.6 million and an
increase in net operating assets of $7.1 million, partially offset by non-cash
charges of $107.3 million. The cash used in operations was due primarily to the
ongoing funding of our sales, marketing and product development activities in
order to attain future growth. The non-cash charges primarily consisted of
impairment on assets held for sale, stock-based compensation expense,
depreciation and amortization, revaluation of embedded derivatives, foreign
exchange impacts, and non-cash lease expense. The increase in net operating
assets is primarily due to increases in accounts receivable as a result of
increased sales, inventory as a result of building safety stock, and prepaid
expenses and other assets. The increase in net operating assets was partially
offset by increases in accounts payable and accrued compensation due to the
accrual of annual and retention bonuses.

During the year ended December 31, 2020, net cash used in operating activities
was $35.7 million, consisting primarily of a net loss of $72.3 million and a
decrease in net operating assets of $13.0 million, partially offset by non-cash
charges of $23.7 million. The cash used in operations was due primarily to the
ongoing funding of our sales, marketing and product development activities in
order to attain future growth. The non-cash charges primarily consisted of
stock-based compensation expense, depreciation and amortization, revaluation of
embedded derivatives, foreign exchange impacts, and non-cash lease expense. The
decrease in net operating assets is primarily due to decreases in accounts
receivable and inventory as well as increases in

accounts payable and accrued compensation due to improved working capital management and lower production than the prior year.



During the year ended December 31, 2019, net cash used in operating activities
was $27.3 million, consisting primarily of a net loss of $43.0 million and an
increase in net operating assets of $7.1 million, partially offset by non-cash
charges of $22.8 million. The cash used in operations was due primarily to an
increase in headcount and related expenses to support the ongoing
commercialization of our PROPEL family of products and the launch of SINUVA in
March 2018. The non-cash charges primarily consisted of stock-based compensation
expense. The increase in net operating assets is primarily due to an increase in
inventory.

Net Cash Provided by (Used in) Investing Activities

During the year ended December 31, 2021, net cash provided by investing activities was $49.2 million, consisting primarily of net maturities of short-term investments of $51.2 million, partially offset by purchases of property and equipment of $2.0 million.

During the year ended December 31, 2020, net cash used in investing activities was $22.7 million, consisting primarily of net purchases of short-term investments of $39.7 million, purchases of property and equipment of $0.9 million, and $16.9 million related to the acquisition of Fiagon, partially offset by proceeds from the sale of short-term investments of $34.8 million.

During the year ended December 31, 2019, net cash provided by investing activities was $18.9 million, consisting primarily of net maturities of short-term investments of $22.6 million, partially offset by purchases of property and equipment of $3.7 million.

Net Cash Provided by Financing Activities



During the year ended December 31, 2021, net cash provided by financing
activities was $36.6 million, consisting of net proceeds from the issuance of
long-term debt of $49.6 million and $7.3 million from the issuance of common
stock upon exercises of employee stock options and purchases under our employee
stock purchase plan, partially offset by $20.3 million related to the payment of
deferred acquisition related consideration.

During the year ended December 31, 2020, net cash provided by financing
activities was $68.7 million, consisting of net proceeds from the issuance of
convertible debt of $61.8 million and $6.9 million from the issuance of common
stock upon exercises of employee stock options and purchases under our employee
stock purchase plan.

During the year ended December 31, 2019, net cash provided by financing
activities was $19.5 million, consisting of net proceeds from the issuance of
common stock upon exercises of employee stock options and purchases under our
employee stock purchase plan.

Liquidity



Based on our current expectations of the operating environment in 2022, as well
as the Deerfield Loans obtained in July 2021 and the Medtronic Financing
obtained in September 2021, we believe we have adequate cash and other resources
to operate for at least twelve months as a standalone entity from the issuance
of this Annual Report on Form 10-K, including funding our working capital needs,
capital expenditures, payments associated with the Fiagon acquisition, interest
payments on long-term debt, lease payments, and other known commitments and
contingent liabilities. However, the extent to which the COVID-19 pandemic may
continue to materially adversely impact our liquidity is uncertain.


Our cash requirements include the following contractual and other obligations:




Debt

As of December 31, 2021, we had $115.0 million of long-term debt outstanding,
inclusive of $65.0 million of Convertible Notes, $20.0 million of Deerfield
Loans, and $30.0 million of Medtronic Financing. None of the principal on our
long-term debt or the interest payments associated with the Medtronic Financing
are current; however, accrued interest as of December 31, 2021 in the amount of
$1.0 million pertaining to the Convertible Notes and Deerfield Loans is due
within the next twelve months.
                                       57

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

Table of Contents



Our obligations under the Deerfield Loans are secured by substantially all of
our assets, which includes springing control of our primary deposit and security
accounts pursuant to a Deposit Account Control Agreement and Security Account
Control Agreement. Deerfield has the ability to exercise exclusive control of
these accounts by providing a Notice of Exclusive Control in response to an
event of default. As of December 31, 2021, no such notice has been received.


Deferred Purchase Acquisition

Under the terms of the Purchase Agreement for the acquisition of Fiagon totaling
€62.5 million, we made an initial €15.0 million ($17.6 million) payment upon
closing, a €15.0 million payment plus a €2.5 million purchase price adjustment
in October 2021, and will make two annual payments of €15.0 million in each of
October 2022 and 2023. In accordance with the terms of the Purchase Agreement,
we were required to place $17.5 million (€15.0 million) in escrow with the
seller as beneficiary. The amount placed in escrow is required to be adjusted to
the equivalent of €15.0 million on January 15th and July 15th of each year based
on the end of the prior month's five-day trailing exchange rate.


Retention Bonuses



On September 1, 2021, the Compensation Committee of our Board of Directors
approved the implementation of a retention program that covers substantially all
of our employees. The program provides for the payment of up to $15.0 million,
payable in cash. The timing and amounts of the payments related to this program
will depend on the timing of the anticipated Merger and employees remaining
active through the earning dates. We are currently recognizing program costs in
our consolidated financial statements ratably over the period of service from
September 1, 2021 through July 31, 2022. During the year ended December 31,
2021, total costs for the retention program were $7.9 million. As of
December 31, 2021, accrued retention bonuses of $7.9 million are due within
twelve months.


Leases

We have lease arrangements for certain facilities, including corporate, manufacturing, and warehouse space. As of December 31, 2021, we had fixed lease payment obligations of $24.5 million, with $3.6 million due within twelve months.




Purchase Obligations

Our purchase obligations primarily consist of non-cancellable obligations to acquire inventory, professional services, software subscriptions, and other goods and services. As of December 31, 2021, we had purchase obligations of $12.0 million, with $9.4 million due within twelve months.



If the proposed Merger with Medtronic is not executed and our current sources of
liquidity are insufficient, we may seek to raise additional capital. If we raise
additional funds by issuing equity securities, our stockholders would experience
dilution. Any additional capital that we raise may contain terms that are not
favorable to us or our stockholders. Additional financing may not be available
at all, or in amounts or on terms unacceptable to us. If we are unable to obtain
additional financing, we may be required to delay the development,
commercialization and marketing of our products.

Critical Accounting Policies, Significant Judgments, and Use of Estimates



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 U.S. generally accepted accounting principles. The
preparation of these consolidated financial statements requires us to make
estimates and assumptions for the reported amounts of assets, liabilities,
revenue, expenses and related disclosures. Our estimates are based on our
historical experience and on various other factors that we believe are
reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying value of assets and liabilities that are not
readily apparent from other sources. Actual results may differ from these
estimates under different assumptions or conditions and any such differences may
be material.

While our significant accounting policies are more fully described in Note 2 of
our consolidated financial statements included in this Annual Report, we believe
the following discussion addresses our most critical accounting policies, which
are those that are most important to the portrayal of our financial condition
and results of operations and require our most difficult, subjective and complex
judgments.

Revenue Recognition



We recognize revenue when our customer obtains control of promised goods in an
amount that reflects the consideration which we expect to receive in exchange
for those goods. To determine revenue recognition for arrangements that we
determine are within the scope of Accounting Standards Codification Topic 606:
Revenue from Contracts with Customers ("Topic 606"), we perform the following
five steps: (i) identify the contract with a customer; (ii) identify the
performance obligations in the contract; (iii) determine the transaction price;
(iv) allocate the transaction price to the performance obligations in the
contract; and (v) recognize revenue when, or as, we satisfy the performance
obligations. We only apply the five-step model to contracts when it is probable
that we will collect the consideration we are entitled to in exchange for the
goods we transfer to the customer. At contract inception, once the contract is
determined to be within the scope of Topic 606, we assess the goods promised
within each contract and determine those that are performance obligations and
assess whether each promised good is distinct. The contracts are typically in
the form of a purchase order from the customer. We then recognize as revenue the
amount of the transaction price that is allocated to the respective performance
obligation when, or as, the performance obligation is satisfied. We must make
assumptions regarding the future collectability of amounts receivable from
customers to determine whether revenue recognition criteria have been met. The
amount of variable consideration that is included in the net sales price may be
constrained, and is included in the net sales price, or transaction price, only
to the extent that we estimate it is probable that a significant reversal in the
amount of the cumulative revenue recognized will not occur in a future period.
We expense shipping and handling costs as incurred and include them in the cost
of sales. In those cases where shipping and handling costs are billed to
customers, we classify the amounts billed as a component of revenue. Taxes
collected from customers and remitted to governmental authorities are excluded
from revenues. We expense any incremental costs of obtaining a contract as and
when incurred as the expected amortization period of the incremental costs would
have been less than one year.

The PROPEL family of products are regulated by the FDA as medical devices. We
recognize revenue through sales of our PROPEL family of products to hospitals
and ASC located almost entirely in the United States when control of the product
is transferred to the customer, typically upon shipment of goods to the
customer, satisfying our only performance obligation.

The FDA has approved SINUVA as a drug and it is therefore regulated as such. We
sell SINUVA to a limited number of specialty pharmacies and specialty
distributors in the United States, or Resellers. These Resellers subsequently
sell SINUVA to health care providers. Revenue from SINUVA sales are recognized
when control of the product is transferred to the Resellers, typically upon
receipt of goods by the Reseller, satisfying our only performance obligation. We
also recognize Reseller fees, prompt pay discounts, product sale discounts,
rebates, returns and other allowances as a reduction of revenue in the same
period the related revenue is recognized. In addition to the agreements with the
Resellers, we enter into arrangements with governmental agencies that result in
rebates, chargebacks and discounts with respect to the purchase of SINUVA. These
amounts may include Medicaid and Tricare rebates, chargebacks related to Federal
Supply Schedule of the General Services Administration, Distribution and Pricing
Agreement with the Department of Defense and 340B of the Public Health Service
Act as well as other allowances that may be offered within contracts between us
and our direct or indirect customers relating to our sales of SINUVA,
collectively referred to as "Discounts and Rebates." Discounts and Rebates are
based on amounts owed or expected to be owed on the related sales. These
estimates take into consideration our historical experience, the shelf life of
the product, current contractual and statutory requirements, specific known
market events and trends and industry data. Overall, these reserves reflect our
best estimates of the amount of consideration to which we are entitled based on
the terms of the contract. If actual results in the future vary from our
estimates, we will adjust these estimates, which would affect revenue and
earnings in the period such variances become known. On the consolidated balance
sheets, such amounts are generally classified as reductions of accounts
receivable if the amount is payable to the Resellers, or a current liability if
the amount is payable to a party other than the Reseller.

Inventories



Inventories are valued at the lower of cost, computed on a first-in, first-out
basis, or net realizable value. The allocation of production overhead to
inventory costs is based on normal production capacity. Abnormal amounts of idle
facility costs, freight, handling costs, and consumption are expensed as
incurred, and not included in allocable overhead. In periods where the
manufacturing is below normal capacity, we will record idle facility charges. We
maintain provisions for excess and obsolete inventory based on our estimates of
forecasted demand and, where applicable, product expiration. If actual future
demand or market conditions are less favorable than we predict, additional
inventory write-downs may be required, which could have a material effect on the
results of our operations.

Embedded Derivatives Related to Convertible Debt Instruments



The Convertible Notes due in May 2025 have embedded features which were required
to be bifurcated upon issuance and then periodically remeasured to fair value
separately as embedded derivatives. These embedded features include additional
make-whole interest payments which may become payable to the lender upon certain
events, such as a change in control, upon optional redemption by our company, or
a sale of all or substantially all of our assets. The embedded features also
include additional shares depending on the time to maturity and the stock price
which may be added to an early conversion upon certain events. We have utilized
a convertible lattice model to determine the fair value of the embedded
features, which utilizes inputs including the common stock price, volatility of
common stock, credit rating, probability of certain triggering events and time
to maturity. The embedded features are remeasured to fair value at each balance
sheet date with a resulting gain or loss related to the change in the fair value
being recorded to other income (expense), net in the consolidated statements of
operations. As of December 31, 2021, the fair value of the embedded derivatives
was $16.2 million and has been presented together with the Convertible Notes
host instrument on the consolidated balance sheets. Changes in our assumptions
used to value the embedded derivatives, such as our stock price and the
estimated probability of triggering events, could result in material changes in
the valuation in future periods. As of December 31, 2021, the maximum value of
the liability if a triggering event had occurred would have been $18.6 million.

Assets Held for Sale



We consider assets to be held for sale when our management approves and commits
to a plan to dispose of an asset or disposal group. Assets or disposal groups
held for sale are recorded initially at the lower of carrying value or estimated
fair value, less estimated costs to sell, and adjusted quarterly. Any initial
loss and quarterly changes are limited to the carrying value at the date of held
for sale classification and are reflected in impairment on assets held for sale
in the consolidated statements of operations and comprehensive loss. Upon
designation as an asset held for sale or disposal group, we stop recording
depreciation and amortization expense on such assets. Costs to sell a disposal
group include incremental direct costs to transact the sale and represent the
costs that result directly from and are essential to a sale transaction that we
would not have incurred had the decision to sell not been made. To the extent
that there are losses in excess of the carrying value as of the date of held for
sale classification of the assets or disposal group, the losses are recognized
upon the date of sale.

The various assets and liabilities of a disposal group are classified as held
for sale and presented separately in the appropriate current asset and current
liability sections of the consolidated balance sheets prior to the date of sale.

Goodwill and Acquired Intangible Assets

Goodwill represents the excess of the purchase price over the fair value of net
identifiable assets and liabilities and is allocated to reporting units on a
relative fair value basis. Acquired identifiable intangible assets include
developed technology, distribution network, customer relationships, and
trademarks. All of our acquired identifiable intangible assets have finite lives
and are amortized over the period of estimated benefit on a straight-line basis,
reflecting the pattern of economic benefits associated with these assets.
Goodwill and acquired intangible assets with indefinite lives are not amortized,
but are subject to an annual impairment review in the third quarter, or if
circumstances indicate their carrying value may no longer be recoverable.

The valuation and classification of goodwill and acquired intangible assets and
the assignment of useful lives for purposes of amortization involves judgments
and the use of estimates. The evaluation of goodwill and these intangible assets
for impairment under established accounting guidelines is required on a
recurring basis. Changes in business conditions could potentially require future
adjustments to the assumptions made. A considerable amount of judgment is
required in assessing impairment, which includes financial forecasts. If
conditions are different from management's current estimates, material
write-downs may be required, which would adversely affect our operations
results.

The annual goodwill impairment test and quarterly reviews of recoverability of
intangible assets conducted in 2021 did not identify impairment associated with
goodwill or acquired intangible assets; however, both goodwill and acquired
intangible assets were subsequently fully impaired as result of the Fiagon
business meeting the criteria for presentation as a held for sale disposal group
and the expectation that a sale will be completed contingent on and coterminous
with the Medtronic Merger.

Business Combinations

We record assets acquired and liabilities assumed at their respective fair
values as of the acquisition date. The excess of the fair value of the purchase
consideration transferred over the fair value of net assets acquired is recorded
as goodwill. Deferred acquisition related consideration incurred is recorded at
its present value and is increased to the ultimate payment amount using the
effective interest rate method. The liability is discounted at a market
participant's borrowing rate for debt

instruments with similar maturities, security, and other characteristics.
Because the purchase consideration is denominated in Euros, it will be
remeasured to US Dollars at each subsequent reporting period, with any foreign
currency gains and losses recognized in other income (expense). When determining
the fair value of assets acquired and liabilities assumed, management is
required to make certain estimates and assumptions, especially with respect to
acquired intangible assets. We engaged a third-party specialist to assist with
this determination. The estimates and assumptions used in valuing intangible
assets include, but are not limited to, the amount and timing of projected
future cash flows, the discount rate used to determine the present value of
these cash flows, and the determination of the assets' life cycles. These
estimates are inherently uncertain and, therefore, actual results may differ
from the estimates made.

The deferred acquisition liability is payable in Euros and subject to foreign
currency risk as it is remeasured at each balance sheet date. To mitigate these
risks, we have entered into foreign exchange forward contracts to reduce the
risk that our earnings and cash flows will be adversely affected by changes in
exchange rates. Due to differing notional amounts and the timing of when the
forward contracts are operable, the impacts of foreign exchange may not be fully
offset.

Stock-based Compensation

We maintain an equity incentive plan to provide long-term incentive for
employees and members of the Board of Directors. The plan allows for the
issuance of non-statutory and incentive stock options and restricted stock units
to employees and non-statutory stock options to consultants and non-employee
directors.

We are required to determine the fair value of equity incentive awards and
recognize compensation expense for all equity incentive awards made to employees
and directors. Stock-based compensation expense is recognized over the requisite
service period in the consolidated statements of operations and comprehensive
loss. We use the straight-line method for expense attribution for awards with
service-based conditions only, and use an accelerated attribution method for
awards with performance and market conditions. We have elected to account for
forfeitures when they occur.

The valuation model we use for calculating the fair value of awards for
stock-based compensation expense, except for market-based awards, is the
Black-Scholes option-pricing model, or the Black-Scholes model. For market-based
awards, the Monte Carlo simulation model, or the Monte Carlo simulation, is
used. Both the Black-Scholes model and Monte Carlo simulation require us to make
assumptions and judgments about the variables used in the calculation, including
the expected term (weighted average period of time that the options granted are
expected to be outstanding), the volatility of our common stock and an assumed
risk-free interest rate. The fair market value of our common stock is determined
based on the closing price of our common stock on the Nasdaq Global Market.
Compensation expense for awards that include a combination of performance and
market conditions is also reassessed quarterly taking into consideration the
expected outcome of the performance component. Changes in these inputs could
result in revised valuations of stock options and market-based awards, impacting
our results of operations.
