Overview



We are a medical dermatology company focused on developing and commercializing
innovative therapeutic products for skin diseases. Our goal is to deliver safe
and efficacious therapies to patients, including developing product candidates
where there are unmet medical needs. We are developing SB206 (berdazimer gel,
10.3%) as a topical prescription gel for the treatment of viral skin infections,
with a current focus on molluscum contagiosum, or molluscum.

In March 2022, we completed the EPI Health Acquisition. EPI Health equips us
with a commercial infrastructure across sales, marketing, and communications, as
well as a dedicated market access and pharmacy relations team, and positions us
as a fully integrated dermatology company with a pipeline of development
candidates focused primarily on dermatological indications, supported by a
commercial platform to market and sell therapeutic products for skin diseases.
We promote products for plaque psoriasis, rosacea and acne. We also have a
pipeline of potential product candidates using our proprietary nitric
oxide-based technology platform, Nitricil, to generate new treatments for
multiple indications.

Further advancement of our molluscum program, including through the potential
approval of SB206, advancement of any other early-stage or late-stage clinical
program across our platform, and continuing our commercial operations until they
are profitable, are all subject to our ability to secure additional capital.
Sources of additional capital may potentially include (i) debt or equity
financings, such as through sales of common stock, or (ii) other sources, such
as partnerships, collaborations, licensing, grants or other strategic
relationships. Any issuance of equity, or debt convertible into equity, would
result in further significant dilution to our existing stockholders.

Please see additional details related to our "Commercial Portfolio" and "Research and Development Portfolio", as described in the section entitled "Business" in this Annual Report.

Business Updates



•In March 2023, we announced that the FDA completed its filing review of our NDA
submitted in early January seeking marketing approval for berdazimer gel, 10.3%
(SB206) for the topical treatment of molluscum contagiosum, or molluscum. The
FDA determined our application was sufficiently complete, no filing review
issues were identified, the substantive review process had commenced, and we
were assigned a Prescription Drug User Fee Act goal date of January 5, 2024.

•For the year ended December 31, 2022, we demonstrated growth in total prescriptions for our actively marketed portfolio:

•Rhofade (oxymetazoline hydrochloride) - 33% annual growth for the year ended December 31, 2022 with 156,664 total prescriptions.

•Wynzora (calcipotriene and betamethasone dipropionate) - 41,023 total prescriptions for the year ended December 31, 2022, as the product was launched in the third quarter of 2021.

•Minolira (minocycline hydrochloride) - 61% annual growth for the year ended December 31, 2022 with 40,641 total prescriptions.



•In late December 2022, we announced that we had entered into an exclusive
license agreement with Sato granting Sato the right to develop, manufacture and
market Rhofade (oxymetazoline hydrochloride 1% cream) for rosacea in the Japan
territory. Under the exclusive license agreement, we received an upfront payment
of $5.0 million in January 2023 and are entitled to receive a $2.5 million
milestone payment at the time of marketing approval in Japan and royalty
payments on net sales of the product in Japan. Sato will be responsible for
obtaining regulatory approval in

                                       59
--------------------------------------------------------------------------------

Japan and will have the right to use our U.S. dossier for Rhofade held by EPI
Health. Sato will also have a right of first negotiation related to Rhofade in
certain other countries in the Asia Pacific region. A portion of the amounts of
the upfront and milestone payments are payable by us to a third party under
contractual obligations related to Rhofade.

•In early December 2022, we announced that we, through EPI Health, entered into
an accounts receivable-backed factoring agreement with Bay View Funding, a
wholly owned subsidiary of Heritage Bank of Commerce. The new $15.0 million
factoring facility provides working capital in an amount that is up to 70% of
our EPI Health subsidiary's gross eligible receivables.

•In July 2022, we announced the publication of positive efficacy and safety data from our completed B-SIMPLE 4 pivotal Phase 3 clinical study evaluating berdazimer gel, 10.3% for the treatment of molluscum in the peer-reviewed journal, JAMA Dermatology.

•In June 2022, we announced the closing of a $15.0 million registered direct offering priced at-the-market under Nasdaq rules with an institutional investor.



•In March 2022, we announced the acquisition of EPI Health, a specialty
pharmaceutical company focused on the U.S. dermatology market. The acquisition
provided the commercial infrastructure for us to become a fully-integrated
specialty dermatology company with a solid pipeline of development candidates
complemented by a commercial foundation. In July 2022, we announced that we had
reached agreement with Evening Post Group, LLC, or EPG, regarding payment,
satisfaction and termination of our $16.5 million secured promissory note and
security agreement associated with the EPI Health Acquisition. We and EPG agreed
that, upon EPG's receipt of $10.0 million, which we subsequently paid, all of
our outstanding indebtedness and obligations under the promissory note were
fully satisfied, and accordingly, the promissory note and related security
agreements were terminated.

Working Capital and Additional Capital Needs



We will continue to need additional funding to support our planned and future
operating activities, to support our commercial operations until they are
profitable and make further advancements in our product development programs
beyond what is currently included in our operating forecast and related cash
projection. We do not currently have sufficient funds to complete
commercialization of any of our product candidates that are under development,
and our funding needs will largely be determined by our commercialization
strategy for SB206 (berdazimer gel, 10.3%), subject to the regulatory approval
process and outcome. We are pursuing a broad range of financing options that
could be used to extend our cash runway and further prepare for
commercialization of SB206 following approval.

Further advancement of our molluscum program, advancement of any other
early-stage or late-stage clinical program across our platform, and supporting
our commercial operations until they are profitable are subject to our ability
to secure additional capital. Sources of additional capital may potentially
include (i) debt or equity financings, such as through sales of common stock, or
(ii) other sources, such as partnerships, collaborations, licensing, grants or
other strategic relationships. Any issuance of equity, or debt convertible into
equity, would result in further significant dilution to our existing
stockholders.

In addition to the regulatory progression of SB206, including implementing
prelaunch strategy and commercial preparation, subject to obtaining additional
financing or strategic partnering, we may progress (a) SB204, a topical
monotherapy for the treatment of acne, by commencing a pivotal Phase 3 study, or
(b) SB019, as a potential intranasal treatment option for respiratory
infections.

As of December 31, 2022, we had total cash and cash equivalents of $12.3 million
and a working capital deficit of $4.0 million. As of December 31, 2022, we had
$48.3 million in remaining availability for sales of our common stock under the
Equity Distribution Agreement dated March 11, 2022, or the Equity Distribution
Agreement, with Oppenheimer & Co., Inc., or Oppenheimer. Pursuant to the Equity
Distribution Agreement, we may from time to time issue and sell our common stock
to or through Oppenheimer, acting as our sales agent, in at-the-market
transactions, subject to certain limitations. See Note 11-"Stockholders' Equity"
to the accompanying consolidated financial statements included in this Annual
Report for more information on the Equity Distribution Agreement. In March 2023,
we consummated a registered direct offering with an institutional investor for
gross proceeds of approximately $6 million, or the March 2023 Registered Direct
Offering. See Note 21-"Subsequent Events" to the accompanying consolidated
financial statements included in this Annual Report for more information on the
March 2023 offering.

Our inability to obtain significant additional funding on acceptable terms could
have a material adverse effect on our business and cause us to alter or reduce
our planned operating activities, including, but not limited to delaying,
reducing, terminating or eliminating planned product candidate development
activities or our preparations for potential commercial launch of SB206
(berdazimer gel, 10.3%), if approved, to conserve our cash and cash equivalents.
We may pursue additional capital through equity or debt financings, including
potential sales under the Equity Distribution Agreement, or from other sources,
including partnerships, collaborations, licensing, grants or other strategic
relationships. Alternatively, we may seek to engage in one or more potential
transactions, which could include the sale of our company, or the sale,
licensing or divestiture of some of our

                                       60
--------------------------------------------------------------------------------

assets, such as a sale of our dermatology platform assets, but there can be no
assurance that we will be able to enter into such a transaction or transactions
on a timely basis or at all on terms that are favorable to us.

If we are unable to obtain significant additional funding on acceptable terms or
progress with a strategic transaction, we may instead determine to dissolve and
liquidate our assets or seek protection under applicable bankruptcy laws. If we
decide to dissolve and liquidate our assets or to seek protection under
applicable bankruptcy laws, it is unclear to what extent we would be able to pay
our obligations, and, accordingly, it is further unclear whether and to what
extent any resources would be available for distributions to stockholders.

Please refer to "Liquidity and Capital Resources" for further discussion of our current liquidity and our future funding needs.

Supply Chain, Manufacturing and Supplies



We currently rely on third-party suppliers to provide the raw materials that are
used by us and our third-party manufacturers in the manufacture of our product
candidates and commercial products.

We have completed the commissioning of our new facility to support various
research and development and cGMP activities, including small-scale
manufacturing capabilities for API and drug product associated with our nitric
oxide product candidates. We are in the process of, and proceeding with the
related preparatory activities associated with, qualifying and validating the
manufacturing equipment for use in API production in preparation for the FDA
pre-approval inspection in connection with our pending NDA for SB206 (berdazimer
gel, 10.3%) as a treatment for molluscum.

Please see additional details related to our "Supply Chain" and "Manufacturing
and Supplies", as described in the section entitled "Business" in this Annual
Report.

Financial Overview

Since our incorporation in 2006 through mid-March 2022, we devoted substantially
all of our efforts to developing our nitric oxide platform technology and
resulting product candidates, including conducting preclinical and clinical
trials and providing general and administrative support for these operations.
With the acquisition of a commercial entity, EPI Health, in March 2022, we have
expanded our business into marketing and sales efforts with a portfolio of
therapeutic products for skin diseases.

To date, we have focused our funding activities primarily on equity raises and
strategic relationships. However, other historical forms of funding have
included payments received from licensing and supply arrangements, as well as
government research contracts.

As of December 31, 2022, we had an accumulated deficit of $310.3 million, and
there is substantial doubt about our ability to continue as a going concern. We
incurred net losses of $31.3 million and $29.7 million in the years ended
December 31, 2022 and December 31, 2021, respectively. We expect to continue to
incur substantial losses in the future as we conduct our planned operating
activities.

Please refer to the section entitled "Management's Discussion and Analysis of
Financial Condition and Results of Operations-Liquidity and Capital Resources"
in this Annual Report for further discussion of our current liquidity and our
future funding needs.

Components of our Results of Operations

Revenue

Net Product Revenues



The EPI Health Acquisition has provided our company with a commercial
infrastructure to sell a marketed product portfolio of therapeutic products for
skin diseases. Net product revenues represent the sales of medical dermatology
products primarily for the treatment of rosacea, plaque psoriasis and acne,
including Rhofade, Wynzora and Minolira.

For additional information regarding our accounting for net product revenues,
see Note 1-"Organization and Significant Accounting Policies" and Note 13-"Net
Product Revenues" to the accompanying consolidated financial statements.

                                       61
--------------------------------------------------------------------------------

License and Collaboration Revenues



License and collaboration revenues consist of (i) the amortization of certain
fixed and variable consideration under the Sato license agreement that was
entered into during the first quarter of 2017, as amended in October 2018, or
the Sato Agreement, that either has been received to date in the form of upfront
and milestone payments or non-contingent milestone payments that become payable
upon the earlier occurrence of specified fixed dates or are contingent milestone
payments that become payable upon the achievement of specified milestone events,
(ii) amounts due under the Sato Rhofade Agreement in the form of upfront and
milestone payments, and (iii) a distribution and supply agreement related to an
out-license of an authorized generic, or AG, version of Cloderm, or Cloderm AG.

For additional information regarding our accounting for license and collaboration revenues, see Note 1-"Organization and Significant Accounting Policies" and Note 14-"License and Collaboration Revenues" to the accompanying consolidated financial statements.

Government Research Contracts and Grants Revenue



Government research contracts and grant revenue relates to the research and
development of our nitric oxide platform for preclinical advancement of NCEs and
formulations related to potential treatments for illnesses in the women's health
field. Revenue related to conditional government contracts and grants is
recognized when qualifying expenses are incurred.

Cost of Goods Sold



Cost of goods sold includes all costs directly incurred to produce net revenues
from our marketed portfolio of medical dermatology products. Cost of goods sold
primarily consist of (i) costs to procure, ship, handle and warehouse our
marketed drug products, and (ii) royalty and milestone expenses incurred in
connection with the various license, collaboration and asset purchase agreements
underlying our marketed portfolio of medical dermatology products.

Research and Development Expenses



Research and development activities include conducting preclinical studies and
clinical trials, manufacturing development efforts and activities related to
regulatory filings for our product candidates. Research and development
expenses, including those paid to third parties for which there is no
alternative use, are expensed as they are incurred. Research and development
expenses include:

•external research and development expenses incurred under agreements with
clinical research organizations, or CROs, investigative sites and consultants to
conduct our clinical trials and preclinical studies;

•costs to acquire, develop and manufacture supplies for clinical trials and preclinical studies at our facilities;



•costs to establish drug substance and drug product manufacturing capabilities
with external contract manufacturing organizations, or CMOs, and to enhance drug
delivery device technologies through partnerships with technology manufacturing
vendors;

•legal and other professional fees related to compliance with FDA requirements;

•licensing fees and milestone payments incurred under license agreements;

•salaries and related costs, including stock-based compensation, for personnel in our research and development functions; and



•facilities, depreciation and other allocated expenses, which include direct and
allocated expenses for rent, maintenance of facilities, utilities, equipment and
other supplies.

We expect that for the foreseeable future, the substantial majority of our
research and development efforts will be focused on (i) technical transfer and
supportive manufacturing activities by our drug product CMO, (ii) operational
testing and validation activities related to the NDA pre-inspection process, and
(iii) regulatory and quality documentation compilation related to our CMC data,
and our drug manufacturing and related processes.

We also expect to incur substantial costs in 2023 associated with our research
and development personnel, and manufacturing capability costs related to the
infrastructure necessary to support small-scale drug substance and drug product
manufacturing operations at our corporate headquarters, including capital costs
subject to depreciation and various ongoing operating costs. We may decide to
revise our development and operating plans or the related timing, depending on
information we learn through our research and development activities, including
regulatory submission updates related to SB206, potential SB206
commercialization strategies, the impact of outside factors such as the COVID-19
pandemic, our ability to enter into strategic arrangements, our ability to
access additional capital and our financial priorities.

                                       62
--------------------------------------------------------------------------------

The successful development and potential regulatory approval of our product
candidates is highly uncertain. At this time, we cannot reasonably estimate the
nature, timing or costs required to complete the remaining development of our
current product candidates or any future product candidates. This is due to the
numerous risks and uncertainties associated with the development of product
candidates. See the "Risk Factors" section in this Annual Report for a
discussion of the risks and uncertainties associated with our research and
development projects.

Selling, General and Administrative Expenses



Our selling, general and administrative expenses consist primarily of salaries
and related costs, including stock-based compensation expenses, for personnel in
our commercial, field sales, marketing, market access, medical affairs,
regulatory, finance, corporate development and other functions. Other selling,
general and administrative expenses include advertising, promotion, travel,
consulting, market research costs, prelaunch strategy costs, medical affairs,
and commercial costs, including commercial preparation activities for our lead
product candidate, SB206, allocated depreciation and facility-related costs,
legal costs of pursuing patent protection of our intellectual property,
insurance coverage and professional services fees for auditing, tax, general
legal, business development, litigation defense and other corporate and
administrative services.

We expect to continue to incur substantial selling, general and administrative
expenses in 2023 in support of our commercial product portfolio and the
prelaunch strategy and commercial preparation activities for SB206. We may
decide to revise our plans or the related timing associated with our commercial
product portfolio, and prelaunch strategy and commercial preparation activities
for SB206, depending on information we learn through our regulatory submission
updates and potential SB206 commercialization strategies.

We also expect to continue to incur substantial selling, general and
administrative expenses in 2023 in support of our operating activities and as
necessary to operate in a public company environment. These expenses include
legal, accounting, regulatory and tax-related services associated with
maintaining compliance with exchange listing and SEC requirements, directors'
and officers' liability insurance premiums and investor relations activities.

Amortization of Intangible Assets

Amortization of intangible assets is associated with the amortization of definite lived intangible assets acquired as part of the EPI Health Acquisition.

For additional information regarding the recognition and amortization of our intangible assets, see Note 7-"Goodwill and Intangible Assets, net" to the accompanying consolidated financial statements.

Change in Fair Value of Contingent Consideration



Contingent consideration is recorded as a liability and is the estimate of the
fair value of potential milestone payments related to the EPI Health
Acquisition. The estimated fair value of contingent consideration was determined
based on a probability-weighted valuation model that measures the present value
of the probable cash payments based upon the future milestone events of EPI
Health at a discount rate that captures the risk associated with the liability
and also based on a Monte Carlo simulation, whereby EPI Health's forecasted net
sales from the EPI Health legacy products were simulated over the measurement
period to calculate the contingent consideration. Contingent consideration is
remeasured at each reporting date and any changes in the liability are recorded
within the consolidated statement of operations and comprehensive loss.

For additional information regarding the valuation of contingent consideration, see Note 19-"Fair Value" to the accompanying consolidated financial statements.

Impairment Loss on Long-lived Assets



During the second quarter of 2021, we assessed the carrying value of a disposal
group classified as assets held for sale in the accompanying consolidated
balance sheets. The disposal group and related assets consisted of certain
manufacturing and laboratory equipment associated with our previous large scale
drug manufacturing capability that was being sold over time through a
consignment seller. Based on our assessment of the disposal group's
recoverability, during the three months ended June 30, 2021, we recognized an
impairment loss on long-lived assets that represented the full write off of its
remaining carrying value.

Other Income (Expense), net



Other income (expense), net consists primarily of (i) foreign currency
adjustments related to the contract asset and contract receivables related to
the Sato Agreement, (ii) interest expense on outstanding notes payable, (iii)
interest income earned on cash and cash equivalents, (iv) gain on extinguishment
of debt related to the forgiveness of our PPP loan and extinguishment of our
note payable related to the EPI Health Acquisition, and (v) other miscellaneous
income and expenses.

                                       63
--------------------------------------------------------------------------------

Financial Information About Segments



Management evaluates performance of the Company based on operating segments.
Segment performance for our two operating segments is based on segment net
revenue and net loss. Our reportable segments consist of (i) research and
development activities related to our nitric oxide-based technology to develop
product candidates, or the Research and Development Operations segment, and (ii)
the promotion of commercial products for the treatment of medical dermatological
conditions, or the Commercial Operations segment. We do not currently evaluate
certain items at the segment level, including certain selling, general and
administrative expenses that result from shared infrastructure, certain expenses
associated with litigation and other legal matters, public company costs (e.g.
investor relations), board of directors and principal executive officers, and
other like shared expenses.

See Note 20-"Segment Information" in the accompanying consolidated financial statements included in this Annual Report for more information about our reportable segments.

Net product revenues

The EPI Health Acquisition provided commercial infrastructure to sell a marketed
product portfolio of therapeutic products for skin diseases. Net product
revenues for the year ended December 31, 2022 were $15.8 million, which were all
generated by our Commercial Operations segment.

Net product revenues represent the sales of medical dermatology products
primarily for the treatment of rosacea, plaque psoriasis, acne and dermatoses,
including Rhofade, Wynzora, Minolira and Cloderm. There were no such net product
revenues in the comparative period in 2021.

For additional information regarding our accounting for net product revenues,
see Note 1-"Organization and Significant Accounting Policies" and Note 13-"Net
Product Revenues" to the accompanying consolidated financial statements included
in this Annual Report.

License and collaboration revenues



License and collaboration revenues were $7.8 million and $2.8 million for the
years ended December 31, 2022 and December 31, 2021, respectively. For the year
ended December 31, 2022, license and collaboration revenue was comprised of
amounts related to (i) the Amended Sato Agreement, related to the Japanese
territory out-license of SB206 and SB204, of $2.6 million, recorded in the
Research and Development Operations segment, (ii) $5.0 million related to the
December 2022 Sato Rhofade Agreement and the related upfront payment, recorded
in the Commercial Operations segment, and (iii) $0.2 million related to the
distribution and supply agreement with Prasco, LLC related to the out-license of
Cloderm AG (the "Prasco Agreement"), recorded in the Commercial Operations
segment.

For the year ended December 31, 2021 license and collaboration revenue was comprised solely of amounts related to the Amended Sato Agreement.



The Amended Sato Agreement and the related revenue recognized is associated with
our performance during the period and the related amortization of the
non-refundable upfront and expected milestone payments under that agreement. A
change in revenue recognized for the years ended December 31, 2022 and
December 31, 2021 relates to a change in estimate related to the expected
duration of the combined SB204 and SB206 development program timeline in July
2021. This most recent change in estimate resulted in a program timeline
extension of the performance period estimate to 10 years, completing in the
first quarter of 2027.

The material terms of the Amended Sato Agreement and the December 2022 Sato Rhofade Agreement and related revenue recognition are described in Note 14-"License and Collaboration Revenues" to the accompanying consolidated financial statements included in this Annual Report.

Government Research Contracts and Grants Revenue



Government research contracts and grants revenue totaled $0.1 million and $0.1
million for the years ended December 31, 2022 and December 31, 2021,
respectively. These amounts relate to (i) a federal grant from the U.S.
Department of Defense's Congressionally Directed Medical Research Programs, and
(ii) a federal grant from the National Institute of Health for certain nitric
oxide based anti-viral therapies and their related development.

Cost of goods sold



Cost of goods sold of $7.4 million for the year ended December 31, 2022 is
recorded by our Commercial Operations segment and includes all costs directly
incurred to produce net product revenues from our marketed portfolio of medical
dermatology products. Cost of goods sold primarily consist of (i) costs to
procure, ship, handle and warehouse our marketed drug products, and (ii) royalty
and milestone expenses incurred in connection with the various license,
collaboration and asset purchase agreements underlying our marketed portfolio of
medical dermatology products.

As part of the Sato Rhofade Agreement and third-party obligations related to our
Rhofade agreements, we accrued 25% of the upfront payment due to us, resulting
in an accrued milestone expense of $1.25 million within cost of goods sold as of
December 31, 2022.

For additional information regarding our accounting for cost of goods sold, see
Note 1-"Organization and Significant Accounting Policies", Note 12-"License and
Collaboration Agreements", Note 13-"Net Product Revenues" and Note 14-"License
and Collaboration Revenues" to the accompanying consolidated financial
statements included in this Annual Report.

Research and development expenses



Our Research and Development Operations segment incurred the substantial
majority of our research and development expenses, which were $16.0 million for
the year ended December 31, 2022, compared to $20.4 million for the year ended
December 31, 2021. The net decrease of $4.4 million, or 22%, was primarily
related to a $4.6 million net decrease in the SB206 program, partially offset by
a $0.2 million increase in other research and development expenses.

In the SB206 program, we experienced (i) a $6.8 million decrease in gross
clinical trial costs primarily due to the B-SIMPLE4 Phase 3 trial execution
activities that occurred during the prior year comparative period, and (ii) a
$0.9 million increase in contra-research and development expense from the
ratable amortization of the Ligand Funding Agreement liability, which represents
Ligand's contribution to specified clinical development and regulatory
activities for SB206 as a treatment for molluscum, partly offset by (iii) a $3.1
million increase in regulatory consulting services, stability and other
analytical testing services, and CMC consulting services and materials in
support of our SB206 NDA submission.

The $0.2 million increase in other research and development expenses was
primarily driven by (i) a $0.8 million net increase in research and development
personnel costs, and (ii) a $0.4 million net increase in research and
development facility operating expenses, partly offset by a $1.0 million net
decrease in preclinical development activity costs, including the SB019 program,
and research and development facility operating expenses.

                                       65
--------------------------------------------------------------------------------

The $0.8 million net increase in research and development personnel costs is
primarily due to (i) a $0.7 million increase in non-cash compensation expense,
including stock based compensation, and (ii) a $0.1 million increase in
recurring salary and benefits costs.

Selling, general and administrative expenses

Selling, general and administrative expenses were $34.1 million for the year ended December 31, 2022, compared to $12.3 million during the year ended December 31, 2021.

The table below sets forth our total selling, general and administrative expenses incurred for the year ended December 31, 2022 and December 31, 2021 and the primary drivers of the fluctuations from the prior period:



                                                                               Selling, general and
                                                                             administrative expenses

EPI Health Acquisition Transaction-related costs                         $                       4,691
EPI Health commercial sales operations                                                          13,733
SB206 prelaunch and commercial preparation                                                       1,103
Tax and insurance costs                                                                            291

The $4.7 million of transaction- and integration-related expenditures incurred
in connection with the EPI Health Acquisition included transaction-related fees
paid to banking advisors, insurance brokers, due diligence costs, and legal,
regulatory, intellectual property, information technology, valuation and
accounting consultants and specialists, and integration-related expenditures
associated with transition services, information technology systems, integration
project management and continued valuation and accounting consultants and
specialists.

The $13.7 million of selling, general and administrative expenses incurred to
support the conduct of EPI Health's commercial sales operations included (i)
$6.9 million of recurring salary, incentive compensation and benefits costs,
(ii) $1.4 million of advertising and promotion costs, (iii) $3.8 million of
administrative costs related to third-party consultants for regulatory services,
external third-party data services and other service providers that support the
commercial sales and operations teams, and (iv) $1.6 million of travel and
expense related costs.

The $1.0 million increase in general and administrative personnel and related
costs includes (i) a $0.9 million increase in non-cash compensation expense
associated with stock based compensation, and (ii) a $0.1 million increase in
recurring salary and benefits costs between the two comparative periods.

Amortization of intangible assets

Amortization of intangible assets of $1.6 million for the year ended December 31, 2022 is associated with the amortization of definite lived intangible assets acquired as part of the EPI Health Acquisition.

For additional information regarding the recognition and amortization of our intangible assets, see Note 7-"Goodwill and Intangible Assets, net" to the accompanying consolidated financial statements included in this Annual Report.

Change in fair value of contingent consideration



For the year ended December 31, 2022, the changes in fair value related to
contingent consideration related to the EPI Health Acquisition related primarily
to changes in market assumptions, management forecasts and discount rates since
the transaction date. For additional information regarding contingent
consideration valuation, see Note 19-"Fair Value" to the accompanying
consolidated financial statements included in this Annual Report.

                                       66
--------------------------------------------------------------------------------

Impairment loss on long-lived assets



During the second quarter of 2021, we assessed the carrying value of a disposal
group classified as assets held for sale in our condensed consolidated balance
sheets. The disposal group and related assets consisted of certain manufacturing
and laboratory equipment associated with our previous large scale drug
manufacturing capability that was being sold over time through a consignment
seller. Based on our assessment of the disposal group's recoverability, during
the year ended December 31, 2021, we recognized a $0.1 million non-cash
impairment loss on long-lived assets that represented the full write off of its
remaining carrying value.

Other income (expense), net

Other income, net was $2.9 million for the year ended December 31, 2022,
compared to $0.2 million for the year ended December 31, 2021. This change was
primarily due to a $4.3 million gain on debt extinguishment recognized in
connection with the termination of the Seller Note during the third quarter of
2022, partially offset by $1.4 million of interest expense related to the Seller
Note issued in March 2022 in connection with the EPI Health Acquisition.

Total other income, net in the comparative 2021 period is primarily comprised of
a $1.0 million gain on extinguishment of debt related to the forgiveness of our
PPP loan in 2021, partially offset by $0.7 million of other expense related to
the impact of foreign currency exchange rate fluctuations for certain time-based
milestones related to the Amended Sato Agreement.

For additional information regarding the Seller Note and the accounting for its termination, see Note 10-"Notes Payable" to the accompanying consolidated financial statements included in this Annual Report.

Liquidity and Capital Resources



As of December 31, 2022, we had an accumulated deficit of $310.3 million. We
incurred net losses of $31.3 million and $29.7 million for the years ended
December 31, 2022 and December 31, 2021, respectively, and there is substantial
doubt about our ability to continue as a going concern. Despite revenues
generated from the sales of commercial products acquired during the EPI Health
Acquisition, we anticipate that we will continue to generate losses for the
foreseeable future, and we expect the losses to increase as we further
commercialize our existing commercial products and continue the development of,
and seek regulatory approvals for, our product candidates and potentially begin
commercialization activities for our product candidates that are currently under
development. We are subject to all of the risks inherent in the
commercialization of drug products, such as risks related to competition, supply
issues or issues that may impact use of our commercial drug products, and in the
development of new pharmaceutical products, and we may encounter unforeseen
expenses, difficulties, complications, delays and other unknown factors that may
adversely affect our business. The sales of our commercial products will
decrease over time if and when they face generic competition or if other risks
materialize, and we do not expect to generate revenue from product sales for our
clinical-stage product candidates unless and until we obtain regulatory approval
from the FDA for such product candidates. We will continue to incur significant
expenses related to the commercialization of our commercial products, and if we
obtain regulatory approval for any of our product candidates, we and/or our
commercial partners and commercial solutions providers would expect to incur
significant expenses related to product sales, marketing, manufacturing and
distribution.

As of December 31, 2022, we had total cash and cash equivalents of $12.3 million
and a working capital deficit of $4.0 million. As discussed below, we used a
portion of our cash and cash equivalents to pay off and terminate the Seller
Note issued in connection with the EPI Health Acquisition, as well as to fund
the EPI Health Acquisition. With the payment and termination of the Seller Note
for a reduced amount of principal, we have removed certain previously existing
liabilities and eliminated the need to make cash payments to service the
interest on the Seller Note going forward. This allows us to use our cash for
development of our product candidates and to support the commercialization of
our products. The payment and termination of the Seller Note removed
encumbrances from the assets of EPI Health and allows us to pursue a broader
range of financing options that could be used to extend our cash runway and to
further prepare for commercialization of SB206 following approval.

From January 1, 2021 through December 31, 2022, we have raised total equity and
debt proceeds of $70.1 million to fund our operations, including (i) $14.0
million in net proceeds from the sale of common stock (or pre-funded warrants in
lieu thereof) and accompanying common warrants in the June 2022 Registered
Direct Offering, (ii) $37.2 million in net proceeds from the sale of common
stock in the June 2021 public offering, (iii) $6.3 million in proceeds from the
sale of common stock under our common stock purchase agreements with Aspire
Capital, (iv) $1.7 million from our Equity Distribution Agreement, (v) a net of
$10.3 million from our accounts receivable factoring facility, (vi) an
additional $0.5 million of proceeds associated with exercises of common stock
warrants issued as part of the March 2020 public offering and March 2020
registered direct offering and (vii) less than $0.1 million of proceeds from the
exercise of stock options.

To date, we have focused our funding activities primarily on equity financings,
while generating additional liquidity and capital through other sources,
including (i) governmental research contracts and grants totaling $12.9 million,
(ii) our licensing and

                                       67
--------------------------------------------------------------------------------

supply arrangements with Sato, totaling $38.1 million, and (iii) $25.0 million
and $12.0 million in proceeds from two funding transactions during the second
quarter of 2019 with Reedy Creek Investments LLC, or Reedy Creek, and Ligand,
respectively.

Going forward, we plan to finance our needs principally from the following:

•equity and/or debt financing, including but not limited to sales under the Equity Distribution Agreement, with certain limitations as described in "Management's Discussion and Analysis of Financial Condition and Results of Operations-Capital Requirements";

•revenues from product sales;

•payments under existing out-license and distribution arrangements for our product candidates and commercial products; and

•payments under current or future collaboration and licensing agreements with strategic partners.



We believe that our existing cash and cash equivalents as of December 31, 2022,
plus expected receipts associated with product sales from our commercial product
portfolio and the proceeds of the March 2023 Registered Direct Offering, will
provide us with adequate liquidity to fund our planned operating needs into the
latter part of the second quarter of 2023. Variability in our operating
forecast, driven primarily by (i) commercial product sales, (ii) timing of
operating expenditures, and (iii) unanticipated changes in net working capital,
will impact our cash runway. This operating forecast and related cash projection
includes (i) costs associated with preparing for and seeking U.S. regulatory
approval of SB206 as a treatment for molluscum (ii) costs associated with the
readiness and operation of our new manufacturing capability necessary to support
small-scale drug substance and drug product manufacturing, (iii) conducting drug
manufacturing activities with external third-party CMOs, (iv) ongoing commercial
operations, including sales, marketing, inventory procurement and distribution,
and supportive activities, related to our portfolio of therapeutic products for
skin diseases acquired with the EPI Health Acquisition, and (v) initial efforts
to support potential commercialization of SB206, but excludes additional
operating costs that could occur between the NDA submission for SB206 through
NDA approval, including, but not limited to, marketing and commercialization
efforts to achieve potential launch of SB206. We may decide to revise our
development and operating plans or the related timing, depending on information
we learn through our research and development activities, including regulatory
efforts related to SB206, potential commercialization strategies, the impact of
outside factors such as the COVID-19 pandemic, our ability to enter into
strategic arrangements, our ability to access additional capital and our
financial priorities.

We will need significant additional funding to continue our operating
activities, make further advancements in our product development programs and
potentially commercialize any of our product candidates beyond those activities
currently included in our operating forecast and related cash projection.
Therefore, we will need to secure additional capital or financing and/or delay,
defer or reduce our cash expenditures before the end of the second quarter of
2023. There can be no assurance that we will be able to obtain additional
capital or financing on terms acceptable to us, on a timely basis or at all.

Our inability to obtain significant additional funding on acceptable terms could
have a material adverse effect on our business and cause us to alter or reduce
our planned operating activities, including, but not limited to delaying,
reducing, terminating or eliminating planned product candidate development
activities, furloughing employees or reducing the size of the workforce, to
conserve our cash and cash equivalents. We may pursue additional capital through
equity or debt financings, including potential sales under the Equity
Distribution Agreement, or from other sources, including partnerships,
collaborations, licensing, grants or other strategic relationships.
Alternatively, we may seek to engage in one or more potential transactions,
which could include the sale of our company, or the sale, licensing or
divestiture of some of our assets, such as a sale of our dermatology platform
assets, but there can be no assurance that we will be able to enter into such a
transaction or transactions on a timely basis or at all on terms that are
favorable to us.

If we are unable to obtain significant additional funding on acceptable terms or
progress with a strategic transaction, we may instead determine to dissolve and
liquidate our assets or seek protection under applicable bankruptcy laws. If we
decide to dissolve and liquidate our assets or to seek protection under
applicable bankruptcy laws, it is unclear to what extent we would be able to pay
our obligations, and, accordingly, it is further unclear whether and to what
extent any resources would be available for distributions to stockholders.

Our cash and cash equivalents are held in a variety of interest-bearing
instruments, including money market accounts. Cash in excess of immediate
requirements is invested with a view toward liquidity and capital preservation,
and we seek to minimize the potential effects of concentration and degrees of
risk.

                                       68
--------------------------------------------------------------------------------

Factoring Arrangement



As discussed further in Note 9-"Commitments and Contingencies" to the
accompanying consolidated financial statements included in this Annual Report,
EPI Health entered into an accounts receivable-backed factoring agreement with
Bay View. Pursuant to the Factoring Agreement, EPI Health may sell certain trade
accounts receivable to Bay View from time to time, with recourse. The factoring
facility provides for EPI Health to have access to the lesser of (i) $15.0
million, or the Maximum Credit, or (ii) the sum of all undisputed receivables
purchased by Bay View multiplied by 70% (which percentages may be adjusted by
Bay View in its sole discretion), less any reserved funds. Upon receipt of any
advance, EPI Health will have sold and assigned all of its rights in such
receivables and all proceeds thereof. EPI Health factors the accounts receivable
on a recourse basis. Therefore, if Bay View cannot collect the factored accounts
receivable from the customer, EPI Health must refund the advance amount remitted
to it for any uncollected accounts receivable from the customer.

As of December 31, 2022, $10.3 million of advances were outstanding under the
factoring facility. The proceeds of the factoring will be used to fund general
working capital needs. We have been and will be charged a financing and
factoring fee in connection with the Factoring Agreement, and the extent to
which we can utilize the Factoring Agreement is limited to the Maximum Credit
and dependent on the extent to which we generate qualifying accounts receivable.

March 2022 Equity Distribution Agreement - At-the-Market Facility



On March 11, 2022, we entered into an Equity Distribution Agreement, or the
Equity Distribution Agreement, with Oppenheimer & Co. Inc., or Oppenheimer.
Pursuant to the Equity Distribution Agreement, we may from time to time issue
and sell to or through Oppenheimer, acting as our sales agent, shares of our
common stock, par value $0.0001 per share having an aggregate offering price of
up to $50.0 million. Sales of the shares, if any, will be made by any method
permitted by law deemed to be an "at the market offering" as defined in Rule
415(a)(4) promulgated under the Securities Act, or, if expressly authorized by
us, in privately negotiated transactions. As sales agent, Oppenheimer will offer
the shares at prevailing market prices and will use its commercially reasonable
efforts, consistent with its sales and trading practices, to sell on our behalf
all of the shares requested to be sold by us, subject to the terms and
conditions of the Equity Distribution Agreement. We or Oppenheimer may suspend
the offering of the shares upon proper notice to the other party. The offering
of the shares pursuant to the Equity Distribution Agreement will terminate upon
the sale of shares in an aggregate offering amount equal to $50.0 million, or
sooner if either we or Oppenheimer terminate the Equity Distribution Agreement
as permitted by its terms. We will pay Oppenheimer a commission in connection
with sales under the Equity Distribution Agreement, and the extent to which we
can utilize the Equity Distribution Agreement is limited by factors such as
market conditions and the terms of the Equity Distribution Agreement.

During the year ended December 31, 2022, we sold 645,105 shares of our common stock at an average price of approximately $2.66 per share for total net proceeds of $1.7 million under the Equity Distribution Agreement.



See Note 11-"Stockholders' Equity" to the accompanying consolidated financial
statements included in this Annual Report for additional information regarding
Equity Distribution Agreement.

June 2022 Registered Direct Offering



On June 9, 2022, we entered into a securities purchase agreement with an
institutional investor, or the Purchaser, pursuant to which we agreed to issue
and sell to the Purchaser, in a registered direct offering priced at-the-market
under Nasdaq rules, or the June 2022 Registered Direct Offering (i) 2,080,696
shares, or the June 2022 Shares of our common stock, and accompanying common
stock warrants, or the June 2022 Common Warrants, to purchase an aggregate of
2,080,696 shares of common stock, for a combined price of $2.851 per share and
accompanying common warrant, and (ii) pre-funded warrants to purchase 3,180,615
shares of our common stock, or the June 2022 Pre-funded Warrants, and
accompanying common warrants to purchase 3,180,615 shares of common stock, for a
combined price of $2.841 per pre-funded warrant and accompanying common warrant.
The June 2022 Registered Direct Offering closed on June 13, 2022. Net proceeds
from the offering were approximately $14.0 million after deducting fees and
commissions and offering expenses of approximately $0.9 million. Offering costs
were netted against the offering proceeds and recorded to additional paid-in
capital.

As of December 31, 2022, no June 2022 Pre-funded Warrants and 5,261,311 June 2022 Common Warrants are outstanding.



We entered into a placement agent agreement, or the "Placement Agent Agreement,
dated as of June 9, 2022, engaging Oppenheimer to act as the sole placement
agent in connection with the June 2022 Registered Direct Offering. Pursuant to
the Placement Agent Agreement, we agreed to pay Oppenheimer a placement agent
fee in cash equal to 5.0% of the gross proceeds from the sale of the June 2022
Shares, the June 2022 Pre-funded Warrants and the June 2022 Common Warrants, and
to reimburse certain expenses of Oppenheimer in connection with the June 2022
Registered Direct Offering. Each June 2022 Pre-funded Warrant had an exercise
price of $0.01 per share. The June 2022 Pre-funded Warrants were exercisable
immediately upon issuance until all of the June 2022 Pre-funded Warrants were
exercised in full. Each June 2022 Common Warrant is immediately exercisable and
has an exercise price of $2.851 per share and will expire five years from the
date of issuance.

                                       69
--------------------------------------------------------------------------------

The exercise price and the number of shares of common stock purchasable upon the
exercise of the June 2022 Pre-funded Warrants and June 2022 Common Warrants are
subject to adjustment upon the occurrence of specific events, including stock
dividends, stock splits, reclassifications and combinations of the Company's
common stock.

See Note 11-"Stockholders' Equity" to the accompanying consolidated financial
statements included in this Annual Report for additional information regarding
the June 2022 Registered Direct Offering.

EPI Health

Acquisition



On March 11, 2022, we completed the acquisition of EPI Health, a
commercial-stage pharmaceutical company founded in 2017 that focuses on the
commercialization of medical dermatology pharmaceutical products for the
treatment of skin conditions. Following the EPI Health Acquisition, our current
portfolio includes six branded prescription drugs, and we actively promote three
medical dermatological products in the U.S. and derive revenue from the sale of
these branded products through pharmaceutical wholesalers as well as direct to
pharmacies. These prescription dermatology therapies are targeted to patients
with plaque psoriasis, rosacea and acne. The branded and promoted product
portfolio currently includes Wynzora, Rhofade and Minolira.

At closing, we paid or committed to pay non-contingent consideration totaling
$27.5 million, as adjusted for cash, indebtedness, net working capital estimates
and other contractually defined adjustments. The purchase price consisted of (i)
$11.0 million paid in cash, (ii) a secured promissory note issued to EPG in the
principal amount of $16.5 million, or the Seller Note, and (iii) a $1.0 million
payment representing an adjustment for estimated net working capital.

The purchase agreement entered into in connection with the EPI Health Acquisition, or the EPI Heath Purchase Agreement, included the potential payment of additional contingent consideration totaling up to $23.0 million upon achievement of certain milestones.

See Note 2-"Acquisition of EPI Health" to the accompanying consolidated financial statements included in this Annual Report for additional information regarding the acquisition of EPI Health.

Seller Note Payment and Termination



On July 13, 2022, we reached agreement with EPG regarding payment and
termination of the outstanding $16.5 million Seller Note related to the EPI
Health Acquisition. We achieved this termination by a payment of $10.0 million,
or an approximate 39% discount on the original principal amount of the Seller
Note. In addition to saving $6.5 million of principal with this termination, we
also avoided paying interest over the previous term of the Seller Note of
approximately $4.6 million.

Pursuant to the terms of the Seller Note, there was no penalty for repaying the
Seller Note prior to the end of the term. In connection with the repayment of
the Seller Note, the guaranty agreement between EPG and EPI Health, dated March
11, 2022, was terminated as of July 13, 2022. Accordingly, the liens on the
membership interests and assets of EPI Health were also terminated such that no
obligations with respect to the Seller Note and related securities agreement or
the underlying loan remain outstanding.

See Note 2-"Acquisition of EPI Health" and Note 10-"Notes Payable" to the accompanying consolidated financial statements included in this Annual Report for additional information regarding the acquisition of EPI Health and the Seller Note.

Working Capital Adjustment Payment



On July 7, 2022, we and EPG agreed to the final net working capital adjustment
amount as part of the post-closing adjustment to the estimated purchase price
for the EPI Health Acquisition. The total adjustment amount was positive and in
the amount of $3.1 million, which was paid to EPG on July 7, 2022.

See Note 2-"Acquisition of EPI Health" to the accompanying consolidated financial statements included in this Annual Report for additional information regarding the acquisition of EPI Health.

Licensing Arrangements

Sato Rhofade Agreement



In December 2022, we entered into a license agreement with Sato in which they
were granted an exclusive, royalty-bearing, non-transferable right and license
under certain of EPI Health's intellectual property rights to develop,
manufacture and market Rhofade (oxymetazoline hydrochloride cream, 1%) for the
treatment of rosacea in Japan, or the Sato Rhofade Agreement. In addition, per
the Sato Rhofade Agreement, during a specified time period, Sato has an
exclusive option to negotiate the terms under which its license would be
expanded to include certain other countries in the Asia-Pacific region.

                                       70
--------------------------------------------------------------------------------

In exchange for the license granted to Sato, Sato agreed to pay us the
following: (i) an upfront payment of $5.0 million; and (ii) a milestone payment
of $2.5 million upon receipt of marketing approval of Rhofade for rosacea in the
Japan territory. Sato also agreed to pay tiered royalty payments on net sales of
the licensed product ranging over time from a percentage of net sales in the
mid-teens to a percentage of net sales in the low single digits.

In addition, we are required to pay 25% of the upfront and milestone payment
amounts to a third party under existing contractual obligations related to
Rhofade and will also be required to pay a portion of the royalty amounts
received under the Sato Rhofade Agreement to third parties, after which we will
retain net royalties in the low single digits.

For additional information about the Sato Rhofade Agreement, please refer to
Note 14-"License and Collaboration Revenues" to the accompanying consolidated
financial statements included in this Annual Report.

Wynzora Agreement



Effective as of January 1, 2022, EPI Health entered into an amended and restated
promotion and collaboration agreement with MC2 Therapeutics Limited, or MC2,
relating to the commercialization of Wynzora for treatment of plaque psoriasis
in adults in the United States, or the MC2 Agreement. Pursuant to the MC2
Agreement, which sets forth the collaborative efforts between EPI Health and MC2
to commercialize and promote Wynzora with MC2 in the United States, MC2 granted
EPI Health an exclusive right and license under MC2's intellectual property
rights to sell, or detail (as defined in the MC2 Agreement), and engage in
certain commercialization activities with respect to Wynzora in the United
States.

In exchange for the provision of promotional and commercialization activities, under the terms of the MC2 Agreement, we are entitled to receive:



•Reimbursement for all incremental costs incurred by us for the promotion and
commercialization of Wynzora, including the incremental portion of our personnel
and commercial operating costs. The supply price of Wynzora product inventory is
also considered to be an incremental cost that is reimbursed by MC2.

•A commercialization fee equivalent to a percentage of net sales ranging from
the mid-teens for net sales less than or equal to $65.0 million to the upper
single digits for annual net sales greater than $105.0 million. We collect this
commercialization fee by retaining our portion of the Wynzora product net sales
we collect from our customers, with the remainder of the net sales being
remitted by us to MC2 periodically in the form of a royalty payment, pursuant to
the MC2 Agreement.

•A contingent incentive fee equal to 5% of the first $30.0 million in net sales
of Wynzora sold in the United States by EPI Health in each of the 2022 and 2023
calendar years; provided that such incentive fee shall not exceed $1.5 million
each year and such incentive fee shall not be credited to us until the royalty
payments paid to MC2 surpass the amount of certain commercialization payments
made previously by MC2.

The term of the MC2 Agreement runs until the seventh anniversary of the first
commercial sale of Wynzora (as defined in the MC2 Agreement) or June 30, 2028,
whichever is earlier. Either party may terminate the MC2 Agreement for the other
party's material uncured breach or the bankruptcy or insolvency of the other
party. MC2 may terminate the MC2 Agreement under certain scenarios, including
for convenience with twelve months' advance notice to us, provided that the
termination is not effective unless MC2 pays any unpaid historical liabilities
related to commercialization of Wynzora owed by MC2. In the case of such
termination, MC2 is also required to make an additional sunset payment to us,
paid in installments over the 24 month period following termination. We may
terminate the MC2 Agreement for convenience with twelve months' advance notice
to MC2 provided that the termination is not effective unless we provide MC2 with
a guarantee of the payment of any outstanding royalty payments, to the extent
such royalty payments owed by us exceeds any unpaid historical liabilities
related to commercialization of Wynzora owed by MC2.

For additional information about the Wynzora and MC2 Agreement, please refer to Note 13-"Net Product Revenues" to the accompanying consolidated financial statements included in this Annual Report.

Rhofade Agreements



As described in Note 9-"Commitments and Contingencies" to the accompanying
consolidated financial statements included in this Annual Report, EPI Health
acquired rights to that certain Assignment and License Agreement, whereby EPI
Health licenses certain intellectual property from Aspect Pharmaceuticals, LLC,
or Aspect and such agreement, the Aspect Agreement. Under the terms of the
Aspect Agreement, EPI Health, as successor-in-interest, has exclusive rights to,
and is required to use commercially reasonable efforts to, commercialize the
Rhofade product. EPI Health also has a duty to certain other parties to use
commercially reasonable efforts to commercialize the Rhofade product based on
historical acquisition agreements for Rhofade that were assumed by EPI Health.

The material terms of the Rhofade Agreements and related revenue recognition are

Cash Flows

The following table sets forth our cash flows for the periods indicated:



                                                                              Year Ended December 31,
                                                                              2022                   2021
                                                                                  (in thousands)
Net cash (used in) provided by:
Operating activities                                                  $     (30,882)             $ (24,777)

Net increase in cash, cash equivalents and restricted cash            $     (33,722)             $  11,789

Net Cash Used in Operating Activities



During the year ended December 31, 2022, net cash used in operating activities
was $30.9 million and consisted primarily of a net loss of $31.3 million, with
adjustments for non-cash amounts related primarily to (i) stock-based
compensation expense of $1.9 million, (ii) amortization of definite lived
intangible assets acquired in the EPI Health Acquisition of $1.6 million, (iii)
$1.2 million of depreciation and amortization of property and equipment expense,
(iv) a $1.2 million change in fair value of contingent consideration, (v) $4.3
million related to a gain on the extinguishment of the Seller Note, (vi) $0.6
million accretion of debt discount, (vii) a $0.1 million loss on disposal of
equipment and (viii) a $0.6 million change in cash related to changes in other
operating assets and liabilities. The favorable impacts to cash related to
changes in assets and liabilities was primarily due to (i) a $2.3 million change
in accounts receivable, (ii) a change in accounts payable of $11.0 million, and
(iii) a change in prepaid expenses and other current assets of $0.5 million. The
unfavorable impacts to cash related to changes in (i) deferred revenue of $2.6
million, (ii) research and development service obligation of $1.0 million, (iii)
accrued expenses of $9.4 million, and (iv) a change in other long-term assets
and liabilities of $0.2 million. The change in operating assets and liabilities
and related changes from the prior period partially relate to the continued
operations of the Research and Development Operations segment as it incurs
expenditures to progress SB206, but primarily relate to the recently acquired
EPI Health business, which comprises the Commercial Operations segment. See Note
2-"Acquisition of EPI Health" to the accompanying consolidated financial
statements for additional detail regarding the EPI Acquisition Health and the
related impacts of the opening balances related to the EPI Health Acquisition.

During the year ended December 31, 2021, net cash used in operating activities
was $24.8 million and consisted primarily of a net loss of $29.7 million, with
adjustments for non-cash amounts related primarily to (i) depreciation expense
of $0.3 million, (ii) impairment of long-lived assets of $0.1 million, (iii) a
foreign currency transaction loss of $0.8 million related to fair value
adjustments for payments received and to be received under the Amended Sato
Agreement, (iv) stock-based compensation expense of $0.3 million, (v) a $1.0
million gain on debt extinguishment related to forgiveness of the PPP loan, and
(vii) a $4.3 million favorable change in cash related to changes in other
operating assets and liabilities. The favorable net change in cash related to
changes in assets and liabilities was primarily due to a $1.5 million increase
in deferred revenue associated with (i) the recognition of license and
collaboration revenue of $2.8 million associated with the Company's performance
during the period and (ii) a time-based developmental milestone payment that
became due and payable as of December 31, 2021 of $4.3 million, a $0.7 million
decrease in prepaid insurance, prepaid expenses and other current assets
primarily related to a decrease in certain prepaid service contracts, a $1.3
million increase in accrued expenses, which included a $0.7 million increase
related to goods and services associated with the planning, design and build-out
of our new facility, a $0.5 million increase in accounts payable, and a $0.3
million net change in other long-term assets and liabilities.

Net Cash Used in Investing Activities



During the year ended December 31, 2022, the $18.9 million of net cash used in
investing activities was primarily related to (i) cash used in connection with
the EPI Health Acquisition of $15.1 million, and (ii) $4.3 million in cash used
for purchases of property, equipment and services associated with the build-out
of our corporate headquarters and small-scale manufacturing facility in Durham,
North Carolina, offset by $0.5 million of payments received related to the
landlord funded tenant improvement allowance. See Note 2-"Acquisition of EPI
Health" to the accompanying consolidated financial statements for additional
detail regarding the EPI Health Acquisition.

During the year ended December 31, 2021, the $7.5 million of net cash used in
investing activities included purchases of property, equipment and services
associated with the planning, design and build-out of our new corporate
headquarters and small-scale manufacturing facility in Durham, North Carolina,
offset by payments received related to the landlord funded tenant improvement
allowance. As of December 31, 2021, we also had goods and services associated
with the planning, design and

                                       72
--------------------------------------------------------------------------------

build-out of our new facility of $1.5 million included in accounts payable and other accrued expenses in the accompanying balance sheets, which we settled through cash payments during the first half of 2022.

Net Cash Provided by Financing Activities



During the year ended December 31, 2022, net cash provided by financing
activities was $16.0 million and consisted primarily of (i) net proceeds from
the June 2022 Registered Direct Offering of $14.1 million, (ii) net proceeds
from our factoring arrangement of $10.3 million and (iii) proceeds from the sale
of our common stock pursuant to the Equity Distribution Agreement entered into
in March 2022 of $1.7 million, offset by the repayment and termination of the
Seller Note for $10.0 million.

During the year ended December 31, 2021, net cash provided by financing
activities was $44.1 million and consisted primarily of (i) $37.6 million of
proceeds from the sale of our common stock pursuant to the June 2021 Public
Offering, (ii) $6.3 million of proceeds from the sale of our common stock
pursuant to the July 2020 Aspire CSPA, (iii) $0.5 million of proceeds from the
exercise of common warrants associated with the March 2020 Public Offering and
March 2020 Registered Direct Offering, (iv) $0.1 million of proceeds from the
exercise of stock options, partially offset by $0.4 million of payments of costs
related to the June 2021 Public Offering.

Capital Requirements



As of December 31, 2022, we had a total cash and cash equivalents balance of
$12.3 million and a working capital deficit of $4.0 million. While we currently
generate revenue from our commercial portfolio of products, we do not believe
that such revenues will be sufficient to fund the operating expenses of our
business. To date, we have not generated any revenue from product sales of our
product candidates, and we do not know when, or if, we will generate any such
revenue from our product candidates. We do not expect to generate revenue from
product sales of our product candidates unless, and until, we obtain regulatory
approval of one of our current or future product candidates and achieve
successful commercialization of such product candidate. As of December 31, 2022,
we had an accumulated deficit of $310.3 million.

We will need significant additional funding to support our planned and future
operating activities and make further advancements in our product development
programs beyond what is currently included in our operating forecast and related
cash projection. We do not currently have sufficient funds to complete
commercialization of any of our product candidates, and our funding needs will
largely be determined by our commercialization strategy for SB206, subject to
the NDA regulatory approval process and outcome.

Our ability to continue to operate our business, including our ability to
advance development programs unrelated to SB206, as well as our ability to
progress SB206 for molluscum, if approved, is dependent upon future sales of our
commercial products along with our ability to access additional sources of
capital, including, but not limited to (i) equity or debt financings, including
but not limited to potential sales using the remaining availability under the
Equity Distribution Agreement, or (ii) other sources, such as partnerships,
collaborations, licensing, grants or other strategic relationships. There can be
no assurance that we will be able to obtain new funding on terms acceptable to
us, on a timely basis, or at all. In addition, we agreed to certain limitations
on our ability to raise funds in the short-term through equity financings in
connection with the March 2023 Registered Direct Offering. In particular, we
agreed not to issue any additional securities for 45 days after closing of the
March 2023 Registered Direct Offering and not to make any sales under the Equity
Distribution Agreement for 60 days after closing of the March 2023 Registered
Direct Offering.

Our inability to obtain significant additional funding on acceptable terms could
have a material adverse effect on our business and cause us to alter or reduce
our planned operating activities, including, but not limited to delaying,
reducing, terminating or eliminating planned product candidate development
activities, furloughing employees or reducing the size of the workforce, to
conserve our cash and cash equivalents. Our anticipated expenditure levels may
change if we adjust our current operating plan. Such actions could delay
development or commercialization-related timelines and have a material adverse
effect on our business, results of operations, financial condition and market
valuation. We are also exploring the potential for alternative transactions,
such as strategic acquisitions or in-licenses, sales, out-licenses or
divestitures of some of our assets, or other potential strategic transactions,
which could include a sale of the company. If we were to pursue such a
transaction, we may not be able to complete the transaction on a timely basis or
at all or on terms that are favorable to us.

Our equity issuances during the years ended December 31, 2022 and December 31,
2021, as well as the March 2023 Registered Direct Offering, have resulted in
significant dilution to our existing stockholders. Any future additional
issuances of equity, or debt that could be convertible into equity, would result
in further significant dilution to our existing stockholders.

As of December 31, 2022, we had 24,722,308 shares of common stock outstanding.
In addition, as of December 31, 2022, we had reserved 7,327,414 shares of common
stock for future issuance related to (i) outstanding warrants to purchase common
stock, (ii) outstanding stock options and stock appreciation rights, (iii)
nonvested restricted stock units, and (iv) future issuances under the 2016
Incentive Award Plan. Our common stock consists of 200,000,000 authorized shares
as of December 31, 2022.

                                       73
--------------------------------------------------------------------------------

We have based our projections of operating capital requirements on assumptions
that may prove to be incorrect, and we may use all of our available capital
resources sooner than we expect. Because of the numerous risks and uncertainties
associated with research, development and commercialization of pharmaceutical
products, we are unable to estimate the exact amount or timing of our operating
capital requirements. Our future funding requirements will depend on many
factors, including, but not limited to:

•market acceptance of approved products and successful commercialization of such products by either us or our partners;

•our decision to expand our internal commercialization capabilities;



•the initiation, progress, timing, costs, results, and evaluation of results of
trials for our clinical-stage product candidates, including trials conducted by
us or potential future partners;

•the progress, timing, costs and results of development and preclinical study activities relating to other potential applications of our nitric oxide platform;

•the number and characteristics of product candidates that we pursue;



•the achievement of milestones that would require payment and whether such
milestone payments are paid in cash or shares of our common stock, including
those set forth in "Note 10-Commitments and Contingencies" to the accompanying
condensed consolidated financial statements;

•our ability to enter into strategic relationships to support the continued development of certain product candidates and the success of those arrangements;

•our success in optimizing the size and capability of our new manufacturing facility and related processes to meet our strategic objectives;



•our success in the technical transfer of methods and processes related to our
drug substance and drug product manufacturing with our current and/or potential
future contract manufacturing partners;

•the outcome, timing and costs of seeking regulatory approvals;

•the occurrence and timing of potential development and regulatory milestones achieved by Sato, our licensee for SB204, SB206 and Rhofade in Japan;

•the terms and timing of any future collaborations, licensing, consulting, financing or other arrangements that we may enter into;



•the amount and timing of any payments we may be required to make, or that we
may receive, in connection with the licensing, filing, prosecution, defense and
enforcement of any patents or other intellectual property rights;

•the costs of preparing, filing and prosecuting patent applications, maintaining and protecting our intellectual property rights;

•defending against intellectual property related claims;

•the costs associated with any potential future securities litigation, and the outcome of that litigation;

•the extent to which we in-license or acquire other products and technologies;

•subject to receipt of marketing approval, revenue received from commercial sales or out licensing of our product candidates; and

•revenue received from commercial sales of our existing medical dermatology products.

Contractual Obligations and Contingent Liabilities

Factoring Arrangement

As discussed in Note 9-"Commitments and Contingencies" to the accompanying consolidated financial statements included in this Annual Report, EPI Health entered into the Factoring Agreement with Bay View on December 1, 2022.



In connection with the factoring facility, EPI Health will be charged a finance
fee, defined as a floating rate per annum on outstanding advances under the
Factoring Agreement, equal to the prime rate plus 2.00%, due on the first day of
each month. EPI Health will also be charged a factoring fee of 0.35% of the
gross face value of any trade accounts receivable for each 30 day period after
the trade accounts receivable is purchased. Bay View has the right to demand
repayment of any purchased receivables that remain unpaid for 90 days after
purchase (or 100 days in the case of certain wholesale customers) or with
respect to which any account debtor asserts a dispute.

                                       74
--------------------------------------------------------------------------------

The factoring facility is for an initial term of 12 months and will renew on a
year to year basis thereafter, unless terminated in accordance with the
Factoring Agreement. EPI Health may terminate the facility at any time upon 60
days prior written notice and payment to Bay View of an early termination fee
equal to 0.25% of the Maximum Credit multiplied by the number of months
remaining in the term.

Compensatory Obligations



The Company enters into employment agreements with certain officers and
employees. These agreements are in the normal course of business and contain
certain customary Company controlled termination provisions which, if triggered,
could result in future severance payments.

See Note 16-"Stock Based Compensation" regarding Stock Appreciation Rights, Restricted Stock Units and Stock Options.

Contingent Payment Obligations Related to the Purchase of EPI Health

See Note 2-"Acquisition of EPI Health" for certain contingent payments related to consideration due to EPG upon achievement of certain milestones by EPI Health.

Contingent Payment Obligations from Historical Acquisitions by EPI Health

EPI Health has in the past acquired certain rights to pharmaceutical products
and such arrangements have typically included requirements that EPI Health make
certain contingent payments to the applicable seller as discussed below.

Rhofade. On October 10, 2019, EPI Health entered into an agreement whereby it
acquired certain assets related to Rhofade, or the Rhofade Acquisition
Agreement. In connection with the Rhofade Acquisition Agreement, we are required
to make the following milestone payments to the seller upon reaching the
following net sales thresholds during any calendar year following the closing
date, as defined in the Rhofade Acquisition Agreement:

               Calendar Year Net Sales Threshold       Milestone Payment
              $                       50,000,000      $        5,000,000
              $                       75,000,000      $        5,000,000
              $                      100,000,000      $       10,000,000


Under the terms of the Rhofade Acquisition Agreement, EPI Health assumed certain
liabilities of the prior licensees of the product Rhofade. In particular, we are
required to pay certain earnout payments pursuant to historic acquisition
agreements for Rhofade upon the achievement of net sales thresholds higher than
those set forth above. However, we have not recognized a liability for such
Rhofade milestones based on current and historical sales figures and
management's estimates of future sales.

Cloderm. On September 28, 2018, EPI Health entered into an agreement pursuant to
which it acquired assets related to the product Cloderm. We are required to pay
a low double-digit royalty once cumulative net sales of Cloderm reach $20.8
million, until we have made $6.5 million of royalty payments.

Minolira. On August 20, 2018, EPI Health entered into an agreement pursuant to
which it acquired assets related to the product Minolira. In connection with the
agreement, we are required to make the following milestone payments to the
seller upon reaching cumulative net sales thresholds as defined in the
acquisition agreement:

                  Cumulative Net Sales Threshold          Milestone Payment
              $     10,000,000                           $        1,000,000
              $     20,000,000                           $        1,000,000
              Each additional          $ 20,000,000      $        1,500,000

See Note 12-"License and Collaboration Agreements", Note 13-"Net Product Revenues" and Note 14-"License and Collaboration Revenues" for certain obligations and contingent payments related to license agreements, including those related to our commercial product portfolio.

Facility Leasing Transactions



In January 2021 we entered into a new lease agreement, pursuant to which we
leased space located in Durham, North Carolina to serve as the Company's new
corporate headquarters and support various cGMP activities, as described in the
section entitled "Business-Manufacturing and Supplies" in this Annual Report.

See the section entitled "Properties" in this Annual Report and Note 6-"Leases"
to the accompanying consolidated financial statements included in this Annual
Report for additional information regarding our facility lease.

                                       75
--------------------------------------------------------------------------------

Amended Sato Agreement



Pursuant to the Amended Sato Agreement, we are obligated to supply Sato with all
quantities of licensed products required by Sato for their development
activities in Japan. As part of the Amended Sato Agreement, we and Sato also
agreed to negotiate a commercial supply agreement pursuant to which we or a
third-party contract manufacturer would be the exclusive supplier to Sato of the
API of licensed products for the commercial manufacture of licensed products in
the licensed territory. Additionally, we have agreed to perform certain
oversight, review and supporting activities for Sato, including: (i) using
commercially reasonable efforts to obtain marketing approval of SB204 and SB206
in the U.S, (ii) sharing all future scientific information we may obtain during
the term of the Amended Sato Agreement pertaining to SB204 and SB206, (iii)
performing certain additional preclinical studies if such studies are deemed
necessary by the Japanese regulatory authority, up to and not to exceed a total
cost of $1.0 million, and (iv) participating in a joint committee that oversees,
reviews, and approves Sato's development and commercialization activities under
the Amended Sato Agreement. Additionally, we have granted Sato the option to use
our trademarks in connection with the commercialization of licensed products in
the licensed territory for no additional consideration, subject to our approval
of such use. We cannot estimate if, when or in what amounts such payments will
become due under the Amended Sato Agreement.

The intellectual property rights granted to Sato under the Amended Sato
Agreement include certain intellectual property rights which we have licensed
from UNC. Under our license agreement with UNC described in Note 12-"License and
Collaboration Agreements" to the accompanying consolidated financial statements
included in this Annual Report, we are obligated to pay UNC a running royalty
percentage in the low single digits on net sales of licensed products, including
net sales that may be generated by Sato. Additionally, we are obligated to make
payments to UNC that represent the portion of the Sato upfront and milestone
payments that were estimated to be directly attributable to the UNC intellectual
property rights included in the license to Sato.

We had also previously entered into an agreement with a third party to assist us
in exploring the licensing opportunity which led to the execution of the Sato
Agreement. We are obligated to pay the third party a low-single-digit percentage
of all upfront and milestone payments the Company receives from Sato under the
Amended Sato Agreement.

See Note 12-"License and Collaboration Agreements" to the accompanying consolidated financial statements included in this Annual Report for additional information on the Amended Sato Agreement.

Amendments to Sublicense Agreements with KNOW Bio



Pursuant to the terms of the amendments to the KNOW Bio Agreements that we
entered into in October 2017, we re-acquired from KNOW Bio exclusive, worldwide
rights under certain United States and foreign patents and patent applications
controlled by us as of the execution date of the KNOW Bio Agreements, and
patents and patent applications which became controlled by us during the three
years immediately following the execution date of the KNOW Bio Agreements,
directed towards nitric oxide-releasing compositions and methods of
manufacturing thereof, including methods of manufacturing Nitricil compounds,
and other nitric oxide-based therapeutics, to develop and commercialize products
for all diagnostic, therapeutic, prophylactic and palliative uses for any
disease, condition or disorder caused by certain oncoviruses, or the Oncovirus
Field. KNOW Bio also granted to us an exclusive license, with the right to
sublicense, under any patents and patent applications which became controlled by
KNOW Bio during the three years immediately following the execution date of the
KNOW Bio Agreements and directed towards nitric oxide-releasing compositions and
methods of manufacturing thereof, including methods of manufacturing Nitricil
compounds, and other nitric oxide-based therapeutics, but not towards medical
devices, to develop and commercialize products for use in the Oncovirus Field.
Additionally, KNOW Bio agreed that KNOW Bio would not commercialize any products
in the Oncovirus Field during the first three years following the execution date
of the KNOW Bio Agreements. The three-year period in which new patents and
patent applications are added to the exclusive license and the three-year term
of the commercialization non-compete both expired on December 29, 2018.

In addition to the $0.3 million non-refundable upfront payment we made upon
execution of the KNOW Bio Amendments, we are obligated to make the following
contingent payments in exchange for the rights granted to us in the Oncovirus
Field:

For products that incorporate a certain nitric oxide-releasing composition
specified in the KNOW Bio Amendments and (i) are covered by KNOW Bio patents or
(ii) materially use or incorporate know-how of KNOW Bio or us related to such
composition that is created during the three years immediately following the
execution date of the KNOW Bio Agreements, or the Covered Products, we must make
the following payments to KNOW Bio:

o A milestone payment upon the first time each Covered Product is approved by the FDA for marketing in the Oncovirus Field;

o A royalty in the low single digits on net sales of Covered Products in the Oncovirus Field until the later of the expiration of the KNOW Bio patents covering the applicable Covered Product or the expiration of regulatory exclusivity on the applicable Covered Product; and


                                       76
--------------------------------------------------------------------------------

o  In the event we sublicense the rights to a Covered Product to a third party
in the Oncovirus Field, the Company must pay KNOW Bio a low double-digit
percentage of any clinical development or NDA approval milestones we receive
from the sublicensee for the Covered Product in the Oncovirus Field.

Nitricil is not the nitric oxide-releasing composition specified in the KNOW Bio
Amendments as the subject of the foregoing payments. As such, products based on
Nitricil are not subject to the foregoing milestone, royalty and sublicensing
payment obligations.

The rights granted to us in the Oncovirus Field in the KNOW Bio Amendments
continue for so long as there is a valid patent claim under the KNOW Bio
Agreements, and upon expiration continue on a perpetual non-exclusive basis, and
are subject to the termination rights of KNOW Bio and us that are set forth in
the KNOW Bio Agreements. In addition, under the KNOW Bio Amendments, KNOW Bio
may terminate the rights granted to the Company in the Oncovirus Field without
terminating the Original KNOW Bio Agreements.

See Note 12-"License and Collaboration Agreements" to the accompanying consolidated financial statements included in this Annual Report for additional information on the sublicense agreement with KNOW Bio.

Royalty and Milestone Payments Purchase Agreement with Reedy Creek Investments LLC



In April 2019, we entered into the Purchase Agreement with Reedy Creek pursuant
to which Reedy Creek provided us funding and we are obligated to pay Reedy Creek
certain ongoing quarterly payments. See the section entitled "Management's
Discussion & Analysis of Financial Condition and Results of Operations-Liquidity
and Capital Resources" in this Annual Report and Note 15-"Research and
Development Agreements" to the accompanying consolidated financial statements

Warrants



In our June 2022 Registered Direct Offering, March 2020 Public Offering, and
March 2020 Registered Direct Offering, we issued warrants to purchase shares of
our common stock. The warrants provide each warrant holder with the right to
require net cash settlement of the warrants upon the occurrence of certain
fundamental transactions, provided that such transactions are within our
control. For any fundamental transaction that is not within our control,
including a fundamental transaction not approved by our board of directors, the
warrant holder will only be entitled to receive from us or any successor entity
the same type or form of consideration (and in the same proportion) that is
being offered and paid to our common stockholders in connection with the
fundamental transaction, whether that consideration be in the form of cash,
stock or any combination thereof. In the event of any fundamental transaction,
and regardless of whether it is within our control, the settlement amount of the
warrants (whether in cash, stock or a combination thereof) is determined based
upon a Black-Scholes value that is calculated using inputs as specified in the
warrants, including a defined volatility input equal to the greater of our
100-day historical volatility or 100%.

See the section entitled "Management's Discussion and Analysis-Critical
Accounting Policies and Use of Estimates-Classification of Warrants and
Pre-Funded Warrants Issued in Connection with Offerings of Common Stock" in this
Annual Report and Note 11-"Stockholders' Equity" to the accompanying
consolidated financial statements included in this Annual Report for additional
discussion regarding the terms of the warrants.

Drug Product Manufacturing



We have established a strategic alliance with Orion, a Finnish full-scale
pharmaceutical company with broad experience in drug manufacturing. The alliance
enables Orion to manufacture our topical nitric oxide-releasing product
candidates on our behalf and on the behalf of our global strategic partners. We
have executed a master contract manufacturing agreement to enable technology
transfer and manufacturing of clinical trial materials for future clinical
trials with our topical product candidates.

We enter into various statements of work, under the master contract manufacturing agreement, that govern certain workflows and deliverables, including production of drug product and other manufacturing related services. These statements of work


                                       77
--------------------------------------------------------------------------------

generally provide for termination on notice, and, therefore, we believe that our non-cancelable obligations under these statements of work are not material.

Other



We enter into contracts in the normal course of business, including, but not
limited to, with clinical research organizations for clinical trials, clinical
supply manufacturing, and preclinical research studies, and with manufacturing
related vendors for raw materials, production related equipment, drug product
and drug substance stability testing, supportive consultative services, and
other products and services for operating purposes. These contracts generally
provide for termination on notice, and, therefore, we believe that our
non-cancelable obligations under these agreements are not material.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under SEC rules.

Net Operating Loss and Research and Development Tax Credit Carryforwards



As of December 31, 2022, we had federal and state NOLs of approximately $104.7
million and $65.1 million, respectively. The NOLs begin to expire in 2029 and
2024 for federal and state tax purposes, respectively. Certain of our federal
and state net operating losses have an indefinite carryforward. We have research
and development tax credits of approximately $2.4 million to offset future
federal taxes. These credits begin to expire in 2041.

We record a valuation allowance to offset any net deferred tax assets if, based
upon the available evidence, it is more likely than not that we will not
recognize some or all of the deferred tax assets. We have had a history of net
losses since inception, and, as a result, we have established a 100% valuation
allowance of $39.8 million for our net deferred tax assets as of December 31,
2022. If circumstances change and we determine that we will be able to realize
some or all of these net deferred tax assets in the future, we will record an
adjustment to the valuation allowance.

The Tax Reform Act of 1986 contains provisions which limit the ability to
utilize the net operating loss carryforwards and general business credits,
including the research and development credit in the case of certain events
including significant changes in ownership interests. In accordance with Section
382 of the Code, a change in equity ownership of greater than 50% within a
three-year period results in an annual limitation on our ability to utilize our
NOL carryforwards created during the tax periods prior to the change in
ownership.

During the course of preparing the Company's consolidated financial statements
as of and for the year ended December 31 2021, the Company completed an analysis
under Sections 382 and 383 of the Code of its historical NOL and tax credit
carryforward amounts. If an ownership change, as defined in Section 382, occurs,
it results in a Section 382 limitation that applies to all NOLs and tax credits
generated prior to the ownership change date that can be used to offset taxable
income incurred after the ownership change date. The annual limitation is based
on a company's stock value prior to the ownership change, multiplied by the
applicable federal long-term, tax-exempt interest rate. As a result, a portion
of the prior year net operating loss and tax credit carryforwards were
determined to be limited. The Company did not experience a cumulative ownership
change that would result in a Section 382 limitation during the year ended
December 31, 2022.

See Note 17-"Income Taxes" to the accompanying consolidated financial statements
included in this Annual Report for further details. If an additional change in
equity ownership occurs in the future which exceeds the Section 382 threshold,
our NOL carryforwards and research and development credits may be subject to
additional limitations. Since our net operating loss carryforwards are limited,
if we have taxable income which exceeds the permissible yearly net operating
loss carryforwards, we would incur a federal income tax liability even though
net operating loss carryforwards would be available in future years.

Critical Accounting Policies and Use of Estimates



Our management's discussion and analysis of financial condition and results of
operations is based on our consolidated financial statements, which have been
prepared in accordance with United States generally accepted accounting
principles. The preparation of these consolidated financial statements requires
us to make estimates and assumptions that affect the reported amounts of assets
and liabilities and the disclosure of contingent assets and liabilities at the
date of the consolidated financial statements, as well as the reported revenue
and expenses during the reporting periods. These items are monitored and
analyzed by us for changes in facts and circumstances, and material changes in
these estimates could occur in the future. We base our estimates on 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.

Significant estimates made by us include provisions for product returns,
coupons, rebates, chargebacks, trade and cash discounts, allowances and
distribution fees paid to certain wholesalers, inventory net realizable value,
useful lives of amortizable intangible assets, stock-based compensation, accrued
expenses, valuation of assets and liabilities in business combinations,
developmental timelines related to licensed products, valuation of contingent
consideration and contingencies. Actual results may differ materially and
adversely from these estimates.

Changes in estimates are reflected in reported results for the period in which
they become known. Actual results may differ materially from these estimates
under different assumptions or conditions. To the extent there are material
differences between the estimates and actual results, our future results of
operations will be affected.

While our significant accounting policies are more fully described in the notes
to our consolidated financial statements included elsewhere in this Annual
Report, we believe that the following accounting policies are critical to the
process of making significant judgments and estimates in the preparation of our
consolidated financial statements and understanding and evaluating our reported
financial results.

Business Acquisitions

Business acquisitions are accounted for using the acquisition method of
accounting in accordance with Accounting Standards Codification, or ASC, 805,
Business Combinations, or ASC 805. ASC 805 requires, among other things, that
assets acquired and liabilities assumed be recognized at their fair values, as
determined in accordance with ASC 820, Fair Value Measurements, as of the
acquisition date. For certain assets and liabilities, book value approximates
fair value. In addition, ASC 805 establishes that consideration transferred be
measured at the closing date of the acquisition at the then-current market
price. Under ASC 805, acquisition-related costs (i.e., advisory, legal,
valuation and other professional fees) are expensed in the period in which the
costs are incurred. The application of the acquisition method of accounting
requires us to make estimates and assumptions related to the estimated fair
values of net assets acquired.

Significant judgments are used during this process, particularly with respect to
intangible assets. Generally, intangible assets are amortized over their
estimated useful lives. Goodwill and other indefinite-lived intangibles are not
amortized, but are annually assessed for impairment. Therefore, the purchase
price allocation to intangible assets and goodwill has a significant impact on
future operating results.

See "Note 2-"Acquisition of EPI Health" to the accompanying consolidated financial statements included in this Annual Report for additional discussion, in addition to Note 19-"Fair Value", related to the EPI Health Acquisition.

Revenue Recognition



We account for revenue in accordance with ASC 606, Revenue from Contracts with
Customers, or ASC 606. To determine revenue recognition for arrangements that we
determine are within the scope of ASC 606, we (i) identify the contract with a
customer, (ii) identify the performance obligations within the contract, (iii)
determine the transaction price, (iv) allocate the transaction price to the
performance obligations within the contract, and (v) recognize revenue when (or
as) we satisfy a performance obligation. 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 or services we transfer to the customer.

Net Product Revenues



Net product revenues encompass sales resulting from transferring control of
products to customers, excluding amounts collected on behalf of other third
parties. The amount of revenue recognized is the amount allocated to the
satisfied performance obligation taking into account variable consideration. The
estimated amount of variable consideration is included in the transaction price
only to the extent that it is probable that a significant reversal in the amount
of cumulative revenue recognized will not occur when the uncertainty associated
with the variable consideration is subsequently resolved.

Product sales are recognized at the point in time when a product is delivered
and legal transfer of title has occurred. We record a reduction of the
transaction price for estimated chargebacks, rebates, coupons, discounts and
returns. A liability is recognized

                                       79
--------------------------------------------------------------------------------

for expected sales returns, rebates, coupons, trade and cash discounts,
chargebacks or other reimbursements to customers in relation to sales made in
the reporting period. Payment terms can differ from contract to contract, but no
element of financing is deemed present based on the fact that typical payment
terms are less than 100 days. Therefore, the transaction price is not adjusted
for the effects of a significant financing component. A receivable is recognized
as soon as control over the products is transferred to the customer as this is
the point in time that the consideration is unconditional because only the
passage of time is required before the payment is due.

Variable consideration relates to sales returns, rebates, coupons, trade and
cash discounts, and chargebacks granted to various direct and indirect
customers. We recognize provisions at the time of sale and adjust them if the
actual amounts differ from the estimated provisions.

There can be a significant lag between our establishment of an estimate and the
timing of the invoicing or claim. We believe we have made reasonable estimates
for future rebates and claims, however, these estimates involve assumptions
pertaining to contractual utilization and performance, and payor mix. If the
performance or mix across third-party payors is different from our estimates, we
may be required to pay higher or lower total price adjustments and/or
chargebacks than we had estimated.

See Note 1-"Organization and Significant Accounting Policies" and Note 13-"Net
Product Revenues" to the accompanying consolidated financial statements included
in this Annual Report for additional discussion.

License and Collaboration Revenues

We have entered into various types of agreements that either license our intellectual property to a third party, acquire license rights to intellectual property of a third party, or both.



Agreements where we license our intellectual property to a third party for
development and commercialization in a licensed territory. If the applicable
license is determined to be distinct from the other performance obligations
identified in the arrangement, we recognize revenues from non-refundable,
upfront fees allocated to the license when the license is transferred to the
customer and the customer is able to use and benefit from the license. For
licenses that are bundled with other promises, we utilize judgment to assess the
nature of the combined performance obligation to determine whether the combined
performance obligation is satisfied over time or at a point in time and, if over
time, the estimated performance period and the appropriate method of measuring
progress during the performance period for purposes of recognizing revenue. We
re-evaluate the estimated performance period and measure of progress each
reporting period and, if necessary, adjust related revenue recognition
accordingly. These arrangements often include milestone as well as royalty or
profit-share payments, contingent upon the occurrence of certain future events
linked to the success of the asset in development, as well as expense
reimbursements from or payments to the collaboration partner. Because of the
risk that products in development will not receive regulatory approval, we do
not recognize any contingent payments until regulatory approval becomes
probable. Future sales-based royalties are not recorded until the subsequent
sale occurs.

Agreements where we acquire license rights to, or otherwise access, a third
party's intellectual property for commercialization of the third party's product
in a licensed territory. We also enter into various types of arrangements to
commercialize products. Our services provided to the third party under such
arrangements, in exchange for compensation that may take the form of cost
reimbursements, may include promoting, marketing, selling and distributing the
third party's developed drugs, and may also involve certain license rights
granted to the parties for use of the other party's intellectual property while
providing defined services under the arrangements. We assess the nature of each
such arrangement and the various rights granted and services performed
thereunder.

Royalty revenue from licenses provided to our collaboration partners, which is
based on sales to third parties of licensed products and technology, is based on
the later of when the third-party sale occurs or the performance obligation to
which some or all of the royalty has been allocated has been satisfied.

When we perform and incur marketing and promotional services expense under an
arrangement that is determined to be within the scope of ASC 808, and where such
services are on behalf of a collaboration partner that is not considered a
customer under ASC 606, we recognize a contra-expense that reflects the value of
the cost reimbursement to which we are expected to be entitled in exchange for
those services. Such contractually required reimbursements are reported as a
liability or an asset within the accompanying consolidated balance sheets based
upon the timing of cash receipt from the collaboration partner.

See Note 14-"License and Collaboration Revenues" to the accompanying consolidated financial statements included in this Annual Report for additional discussion.

Intangible Assets and Goodwill



Intangible assets represent identifiable intangible assets including product
rights consisting of pharmaceutical product licenses and patents. Amortization
for pharmaceutical products licenses is computed using the straight-line method
based on the lesser of the term or the useful life of the license. Amortization
for pharmaceutical patents is computed using the straight-line method based on
the useful life of the patent.

                                       80
--------------------------------------------------------------------------------

Definite-lived intangible assets are reviewed for impairment whenever events or
circumstances indicate that carrying amounts may not be recoverable. In the
event impairment indicators are present or if other circumstances indicate that
an impairment might exist, we compare the future undiscounted cash flows
directly associated with the asset or asset group to the carrying amount of the
asset group being evaluated for impairment. If those estimated cash flows are
less than the carrying amount of the asset group, an impairment loss is
recognized. An impairment loss is recognized to the extent that the carrying
amount exceeds the asset's fair value. Considerable judgment is necessary to
estimate the fair value of these assets, accordingly, actual results may vary
significantly from such estimates.

Indefinite-lived intangible assets, including goodwill, are not amortized. We
test the carrying amounts of goodwill for recoverability on an annual basis at
October 1 or when events or changes in circumstances indicate evidence that a
potential impairment exists, using a fair value based test. Goodwill is assessed
at the reporting unit level. We performed a qualitative assessment as of October
1, 2022 and concluded that it is not more likely than not that the fair value of
our reporting unit was less than its carrying amount. A significant amount of
judgment is involved in determining if an indicator of goodwill impairment has
occurred. Such indicators may include, among others: a significant decline in
expected future cash flows, a sustained, significant decline in our stock price
and market capitalization, a significant adverse change in legal factors or in
the business climate, adverse assessment or action by a regulator, and
unanticipated competition. Any change in these indicators could have a
significant negative impact on our financial condition, impact the goodwill
impairment analysis or cause us to perform a goodwill impairment analysis more
frequently than once per year.

See Note 7-"Goodwill and Intangible Assets, net" to the accompanying
consolidated financial statements included in this Annual Report for additional
discussion regarding intangible assets and goodwill related to the EPI Health
Acquisition.

Contingent Consideration

Contingent consideration is recorded as a liability and is the estimate of the
fair value of potential milestone payments related to business acquisitions. The
estimated fair value of contingent consideration is determined based on a
probability-weighted valuation model that measures the present value of the
probable cash payments based upon the future milestone events of EPI Health at a
discount rate that captures the risk associated with the liability and also
based on a Monte Carlo simulation, whereby EPI Health's forecasted net sales
from the EPI Health legacy products is simulated over the measurement period to
calculate the contingent consideration.

Significant increases or decreases in any of the probabilities of success or
changes in expected achievement of any of these milestones would result in a
significantly higher or lower fair value of these milestones, respectively, and
commensurate changes to the associated liability.

The contingent consideration is revalued at each reporting period and changes in fair value are recognized in the consolidated statements of operations and comprehensive loss until settlement.



See Note 2-"Acquisition of EPI Health" to the accompanying consolidated
financial statements included in this Annual Report for additional discussion
regarding purchase consideration, including contingent consideration related to
the EPI Health Acquisition.
