1. Organization and Description of Business
OptiNose, Inc. (the Company) was incorporated in Delaware in May 2010 (inception) and has facilities in Yardley, Pennsylvania, Ewing, New Jersey, and Oslo, Norway. The Company's predecessor entity, OptiNose AS, was formed under the laws of Norway in September 2000. In 2010, OptiNose AS became a wholly-owned subsidiary of the Company as part of an internal reorganization. During 2022, the Company’s board of directors approved the liquidation of Optinose AS and Optinose UK in order to simplify corporate structure.

The Company is a specialty pharmaceutical company focused on the development and commercialization of products for patients treated by ear, nose and throat (ENT) and allergy specialists. The Company's first commercial product, XHANCE® (fluticasone propionate) nasal spray, 93 mcg, is a therapeutic utilizing its proprietary Exhalation Delivery System (EDS) device that delivers a topically-acting corticosteroid for the treatment of chronic rhinosinusitis with nasal polyps and, if approved, chronic rhinosinusitis without nasal polyps (also referred to as chronic sinusitis). XHANCE was approved by the United States (US) Food and Drug Administration (FDA) in September 2017 for the treatment of nasal polyps in patients 18 years of age or older. XHANCE was made widely available through commercial channels in April 2018.
2. Liquidity
Since inception, the Company's operations have focused on organization and staffing, business planning, raising capital, establishing an intellectual property portfolio, conducting preclinical studies and clinical trials, pursuing regulatory approvals and most recently, commercializing XHANCE in the US. As of September 30, 2021,2022, the Company had cash and cash equivalents of $84,226.$61,080. For the nine months ended September 30, 2021,2022, the Company had a net loss of $66,672$59,684 and negative cash from operations of $60,219.$49,971. As of September 30, 2021,2022, the Company had an accumulated deficit of $594,437.$669,745.
The Company is subject to a number of risks similar to other life sciences companies, including, but not limited to, successful discovery, development and commercialization of its products and product candidates, raising additional capital, the development by its competitors of new technological innovations, protection of proprietary technology and market acceptance of the Company's products.
The Company's continuation as a going concern is dependent on its ability to continue to maintain compliance with its covenants under that certain Note Purchase Agreement, dated as of September 12, 2019, as amended pursuant to that certain letter agreement dated as of August 13, 2020 and as further amended by that certain first amendmentamendments to the Note Purchase Agreement dated as of March 2, 2021, November 16, 2021, August 10, 2022 and November 9, 2022 (the Note Purchase Agreement) that the Company entered into with funds managed by Pharmakon Advisors, LP (Pharmakon), the investment manager of the BioPharma Credit Funds (BioPharma), including the minimum trailing twelve-month consolidated XHANCE net sales and royalties the Company is required to achieve each quarter and its ability to generate sufficient cash flows from operations to meet its obligations and/or obtain additional financing from its stockholderscapital through equity or debt financings, partnerships, collaborations, or other sources, as may be required. The Note Purchase Agreement includes events of default, in certain cases subject to customary periods to cure, following which Pharmakon may accelerate all amounts outstanding under the senior secured notes issued pursuant to the Note Purchase Agreement (Pharmakon Senior Secured Notes). The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business.
AsOn November 9, 2022, the Company entered into a Fourth Amendment to the Note Purchase Agreement (the Fourth Amendment). The Fourth Amendment provided a waiver of the filing of this quarterly report on Form 10-Q, the Company expectsminimum consolidated XHANCE net sales and royalties required to be achieved under the Note Purchase Agreement for the trailing twelve-month period ending September 30, 2022 and December 31, 2021 to be between $71,000 and $75,000. If2022 in exchange for a $1,300 fee due on the repayment of the Pharmakon Senior Secured Notes. The Company believes it is unable toprobable that it will not achieve $80,000 ofthe trailing twelve-month minimum consolidated XHANCE net sales and royalties for the trailing twelve-month period ending December 31, 2021 and the Companythresholds that it is unablerequired to obtain a waiver or modification to this financial covenant, the Company will be in breach of a financial covenantachieve under the Note Purchase Agreement which will constitute an event of default underfor the terms of the Note Purchase Agreement. If the holders of the Pharmakon Senior Secured Notes elect to accelerate the repayment of all unpaid principalperiods ending March 31, 2023, June 30, 2023 and accrued interest under such holders’ Pharmakon Senior Secured Notes, the Company may need to delay or curtail its operations. These factors raise substantial doubt about the Company's ability to continue as a going concern.September 30, 2023, which

will constitute a default under the Note Purchase Agreement if the Company is unable to obtain a modification or waiver of such minimum consolidated XHANCE net sales and royalties thresholds. In addition, the Note Purchase Agreement contains financial covenants requiring the Company to maintain at all times a minimum of $30,000 of cash and cash equivalents. If the Company is unable to obtain additional capital or obtain a waiver or modification to this liquidity covenant, the Company believes that it is probable that it will not be able to maintain at least $30,000 of cash and cash equivalents for at least twelve-months following the filing of this Form 10-Q, which will constitute a default of the liquidity financial covenant under the Note Purchase Agreement. In the event of any one of the foregoing defaults, the holders of the Pharmakon Senior Secured Notes may declare an Event of Default under Note Purchase Agreement and may elect to accelerate the repayment of all unpaid principal, accrued interest and other amounts due under such holders’ Pharmakon Senior Secured Notes, which may require the Company to delay or curtail its operations until additional funding is received. These factors raise substantial doubt about the Company's ability to continue as a going concern. The terms of the Note Purchase Agreement and the Pharmakon Senior Secured Notes, including applicable covenants, are described in Note 8.
TheAdditionally, the Company will likely require additional capital in the future secured through equity or debt financings, partnerships, collaborations, or other sources in order to meet its debt service obligations, including repayment, under the Pharmakon Senior Secured Notes, including repayment, and to carry out the Company's planned development and commercial activities. Financial capital, secured through equity financings, partnerships, collaborations, or other sources, may not be available on a timely basis, on favorable terms, or at all, and such capital, if raised, may not be sufficient to meet the Company's debt service obligations, including repayment, or enable the Company to continue to implement its long-term business strategy. If additional capital is not secured,obtained when required, the Company may need to delay or curtail its operations until suchadditional funding is received. The terms of the Note Purchase Agreement, including applicable covenants, are described in Note 8.

3. Basis of Presentation and Summary of Significant Accounting Policies
The accompanying unaudited interim consolidated financial statements have been prepared in conformity with US generally accepted accounting principles (GAAP). Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (ASC) and Accounting Standards Updates (ASU) of the Financial Accounting Standards Board (FASB).
In the opinion of management, the accompanying unaudited interim financial statements include all normal and recurring adjustments (which consist primarily of accruals and estimates that impact the financial statements) considered necessary to present fairly the Company's financial position as of September 30, 20212022 and its results of operations for the three and nine months ended September 30, 20212022 and 20202021 and cash flows for the nine months ended September 30, 20212022 and 2020.2021. Operating results for the three and nine months ended September 30, 20212022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021.2022. The unaudited interim financial statements, presented herein, do not contain the required disclosures under GAAP for annual financial statements. The accompanying unaudited interim financial statements should be read in conjunction with the annual audited financial statements and related notes as of and for the year ended December 31, 20202021 contained in the Company’s annual report on Form 10-K for the year ended December 31, 20202021, filed with the SEC on March 3, 2021.8, 2022.
Use of estimates
The preparation of the unaudited interim consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited interim consolidated financial statements and reported amounts of expenses during the reporting period. Due to the uncertainty of factors surrounding the estimates or judgments used in the preparation of the unaudited interim consolidated financial statements, actual results may materially vary from these estimates. Estimates and assumptions are periodically reviewed and the effects of revisions are reflected in the unaudited interim consolidated financial statements in the period they are determined to be necessary.
Concentration of credit risk
Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash and accounts receivable. The Company generally invests its cash in deposits with high credit quality financial institutions. Additionally, the Company performs periodic evaluations of the relative credit standing of these financial institutions.
Customer and supplier concentration
XHANCE is sold to wholesale pharmaceutical distributors and Preferred Pharmacy Network (PPN) partners, who, in turn, sell XHANCE to pharmacies, hospitals and other customers. NaN customers represented approximately 39% of the Company's accounts receivable at September 30, 2021 and 5 customers represented

institutions. Additionally, the Company performs periodic evaluations of the relative credit standing of these financial institutions.
Customer and supplier concentration
The Company has exposure to credit risk in accounts receivable from sales of product. XHANCE is sold to wholesale pharmaceutical distributors and preferred pharmacy network (PPN) partners, who, in turn, sell XHANCE to pharmacies, hospitals and other customers. Five customers represented approximately 33%40% of the Company's accounts receivable at September 30, 2022 and 32%five customers represented approximately 31% and 29% of the Company's net product sales for the three and nine months ended September 30, 2021, respectively.2022.
The Company currently purchases XHANCE and its components from several third-party suppliers and manufacturing partners, certain of which are available through a single source. Although the Company could obtain each of these components from alternative third-party suppliers, it would need to qualify and obtain FDA approval for another supplier as a source for each such component. The Company has initiated the process of qualifying an alternate third-party supplierssupplier for select components of XHANCE. Alternate third party suppliers of XHANCE components are subject to qualification and approval from the FDA.
Fair value of financial instruments
At September 30, 20212022 and December 31, 2020,2021, the Company's financial instruments included cash and cash equivalents, accounts receivable, grants receivable, accounts payable and accrued expenses. The carrying amounts reported in the Company's financial statements for these instruments approximate their respective fair values because of the short-term nature of these instruments. In addition, the Company believes that at September 30, 2021,2022, the carrying value of long-term debt approximated fair value as the interest rates are reflective of the rate the Company could obtain on debt with similar terms and conditions. At September 30, 20212022 and December 31, 2020,2021, there were no financial assets or liabilities measured at fair value on a recurring basis.
Restricted cash
As of September 30, 20212022 and December 31, 2020,2021, the restricted cash balance included in prepaid expenses and other assets was $9$41 and $23,$13, respectively.
Net product revenues
The Company accounts for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers (ASC 606), which the Company adopted on January 1, 2018. The Company recognizes revenue from XHANCE sales at the point customers obtain control of the product, which generally occurs upon delivery. The transaction price that is recognized as revenue for products includes an estimate of variable consideration. The Company’s estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of its anticipated performance and all information (historical, current and forecasted) that is reasonably available. The components of the Company’s variable consideration include the following:
Provider Chargebacks and Discounts. Chargebacks for fees and discounts to providers represent the estimated obligations resulting from contractual commitments to sell products to qualified healthcare providers at prices lower than the list prices charged to customers who directly purchase the product from the Company. Customers charge the Company for the difference between what they pay for the product and the ultimate selling price to the qualified healthcare providers. These components of variable consideration are established in the same period that the related revenue is recognized, resulting in a reduction of product revenue and accounts receivable.
Trade Discounts and Allowances. The Company generally provides customers with discounts that include incentive fees which are explicitly stated in the Company’s contracts. These discounts are recorded as a reduction of revenue and accounts receivable in the period in which the related product revenue is recognized.
Product Returns. Consistent with industry practice, the Company has a product returns policy that provides customers a right of return for product purchased within a specified period prior to and subsequent to the product’s
12

(in thousands, except share and per share data)
expiration date. The Company estimates the amount of its product that may be returned and presents this amount as a reduction of revenue in the period the related product revenue is recognized, in addition to establishing a liability. The Company considers several factors in the estimation process, including expiration dates of product shipped to customers, inventory levels within the distribution channel, product shelf life, prescription trends and other relevant factors.
Government Rebates. The Company is subject to discount obligations under state Medicaid programs and Medicare. Reserves related to these discount obligations are recorded in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability. The Company’s
12

Table of Contents
OptiNose, Inc.
Notes to Unaudited Interim Consolidated Financial Statements (Continued)
(in thousands, except share and per share data)
liability for these rebates consists of estimates of claims for the current quarter and estimated future claims that will be made for product that has been recognized as revenue but remains in the distribution channel inventories at the end of the reporting period.
Payor Rebates. The Company contracts with certain third-party payors, primarily health insurance companies and pharmacy benefit managers, for the payment of rebates with respect to utilization of its products. These rebates are based on contractual percentages applied to the amount of product prescribed to patients who are covered by the plan or the organization with which it contracts. The Company estimates these rebates and records such estimates in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability.
Patient Assistance. Other programs that the Company offers include voluntary co-pay patient assistance programs intended to provide financial assistance to eligible patients with prescription drug co-payments required by payors and coupon programs for cash payors. The calculation of the current liability for this assistance is based on an estimate of claims and the cost per claim that the Company expects to receive associated with product that has been recognized as revenue but remains in the distribution channel inventories at the end of each reporting period.
Distribution and Other Fees. The Company pays distribution and other fees to certain customers in connection with the sales of its products. The Company records distribution and other fees paid to its customers as a reduction of revenue, unless the payment is for a distinct good or service from the customer and the Company can reasonably estimate the fair value of the goods or services received. If both conditions are met, the Company records the consideration paid to the customer as an operating expense. These costs are typically known at the time of sale, resulting in minimal adjustments subsequent to the period of sale.
Licensing revenues
The Company has license agreements with Inexia Limited (Inexia)Centessa Pharmaceuticals (Centessa) and Currax Pharmaceuticals LLC (Currax). These license agreements provide for exclusive licensed rights to certain intellectual property, a non-refundable up-front payment, potential milestone payment(s) and potential royalty payment(s). The Company analyzed the performance obligations under the license agreements, the consideration received to date and the consideration the Company could receive in the future as part of its analysis related to ASC 606. The Company recognized $1,000 as licensing revenue from Currax during the nine months ended September 30, 2021 and is not eligible to receive any further payments under the Currax license agreement other than reimbursement for certain expenses. The Company does not expect to any receive license revenues under the Centessa agreement in the near term.
Net income (loss) per common share
Basic net income (loss) per common share is determined by dividing net income (loss) applicable to Company common stock (Common Stock) holders by the weighted average common shares outstanding during the period. For the three and nine months ended September 30, 20212022 and 2020,2021, the outstanding Common Stock options, Restricted Stock units, Common Stock warrants and shares to be issued under the Company's 2017 Employee Stock Purchase Plan have been excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive. Therefore, the weighted average shares used to calculate both basic and diluted net loss per share are the same.

Income taxes
In accordance with ASC 270, Interim Reporting, and ASC 740, Income Taxes, the Company is required at the end of each interim period to determine the best estimate of its annual effective tax rate and then apply that rate in providing for income taxes on a current year-to-date (interim period) basis. For the three and nine months ended September 30, 20212022 and 2020,2021, the Company recorded no tax expense or benefit due to the expected current year loss and its historical losses. As of September 30, 20212022 and December 31, 2020,2021, the Company concluded that a full valuation allowance would be necessary for all of its net deferred tax assets. The Company had no amounts recorded for uncertain tax positions, interest or penalties in the accompanying consolidated financial statements.

Recent accounting pronouncements
In July 2021, the FASB issued ASU No. 2021-05, Leases (Topic 842): Lessors—Certain leases with variable payments. ASU No. 2021-05 is intended to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing transactions. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021, with early adoption permitted. The Company is currently evaluating the potential impact of the adoption of this standard on its results of operations, financial position and cash flows and related disclosures.
In May 2021, the FASB issued ASU No. 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. ASU No. 2021-04 requires that issuers clarify and reduce diversity in accounting for modifications or exchanges of freestanding equity-classified written call options that remain equity classified after the modification or exchange. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021, with early adoption permitted. The Company is currently evaluating the potential impact of the adoption of this standard on its results of operations, financial position and cash flows and related disclosures.
In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 eliminated certain exceptions and changed guidance on other matters. The exceptions relate to the allocation of income taxes in separate company financial statements, tax accounting for equity method investments and accounting for income taxes when the interim period year-to-date loss exceeds the anticipated full year loss. Changes relate to the accounting for franchise taxes that are income-based and non-income-based, determining if a step up in tax basis is part of a business combination or if it is a separate transaction, when enacted tax law changes should be included in the annual effective tax rate computation, and the allocation of taxes in separate company financial statements to a legal entity that is not subject to income tax. The Company has adopted ASU 2019-12 in the first quarter of 2021, and there was no significant impact.
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-03, in conjunction with ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, introduces an approach, based on expected losses, to estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale debt securities. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022 for companies deemed to be smaller reporting companies as of November 15, 2019, with early adoption permitted. The Company has adopted ASU 2016-13 and there was no significant impact.

Chronic rhinosinusitis is a serious nasal inflammatory disease that is treated using therapies, such as intranasal steroids (INS), which have significant limitations. We believe XHANCE has a differentiated clinical profile with the potential to become part of the standard of care for this disease because it is able to deliver medication to the primary site of inflammation high and deep in the nasal passages in regions not adequately reached by conventional INS.
In September 2017, the United StatesU.S. Food and Drug Administration (FDA) approved XHANCE for the treatment of nasal polyps in patients 18 years of age or older. XHANCE was made widely available through commercial channels in April 2018.
We have completed two Phase 3b clinical trials of XHANCE for a follow-on indication for the treatment of chronic sinusitis. Positive top-line results from the trials were announced in March and June 2022. Based on the results of these trials, XHANCE has the potential to be the first drug therapy approved by the FDA for the treatment of chronic sinusitis. We plan to submit a supplemental new drug application for XHANCE to the U.S. Food and Drug Administration (FDA) in early 2023. Previously we expected to submit the supplemental new drug application by the end of 2022.
Business Updates in Response to the COVID-19 Pandemic
The COVID-19 pandemic has caused business and economic disruption, and the duration and impact of that disruption is uncertain at this time.
In mid-March 2020, we transitioned to a full-time, virtual work environment in which all employees, including sales representatives (whom we refer to as territory managers), were encouraged to work from their place of residence. Our decision was based on actions taken by federal, state and local governments to contain the spread of severe acute respiratory coronavirus 2 (SARS-CoV-2) and the related Coronavirus Disease 2019 (COVID-19), as well as the impact of “social distancing” efforts and various mitigation actions implemented by healthcare practices across the United States. Shortly after our transition to a full-time, virtual work environment, our territory managers began virtual details of XHANCE to target audience physicians.
We have been monitoring, and will continue to monitor, federal, state, and local government requirements and guidances. In certain instances, the various mitigation efforts have been updated to facilitate a return to a working environment with fewer restrictions. Where permitted by governmental requirements and the policies of physician offices, our territory managers began to return to in-person detailing of physicians in May and June 2020. Given the localized nature of the restrictions that are in place and the potential for restrictions to return, we have equipped our territory managers to operate in an environment that will include a mix of virtual and in-person physician detailing with dependencies on geography and time. We are currently operating under a hybrid-model for our office-based employees which includes a mix of in-office and work-from-home days.
Federal, state and local government requirements and guidances have impacted virtually all of the physicians' offices in which our territory managers detail XHANCE. These impacts include reduced patient visits, temporary halt of territory managers' visits, restrictions imposed on the logistics and frequency of territory managers' visits and temporary closings of physicians' offices. We believe the restrictions imposed on the logistics and frequency of territory managers' visits have now become permanent in some physician officers which is adversely impacting the effectiveness of our sales force.
Late in the first quarter of 2020 we began to observe an adverse impact of the COVID-19 pandemic on XHANCE prescription growth and, as a result XHANCE net revenue. Based on third-party prescription data as well as data from Preferred Pharmacy Network (PPN) partners, XHANCE prescriptions increased 11% from first quarter 2020 to second quarter 2020, increased 11% from second quarter 2020 to third quarter 2020, increased 7% from third quarter 2020 to fourth quarter 2020, decreased 2% from fourth quarter 2020

to first quarter 2021, increased 14% from first quarter 2021 to second quarter 2021, and increased 4% from second quarter 2021 to third quarter 2021. Although XHANCE prescriptions and XHANCE net revenue have grown during this COVID-19 period,since the start of the pandemic, the rate of growth was below our pre-pandemic expectations. Additionally, theThe duration and magnitude of the impact of the COVID-19 pandemic on XHANCE prescriptions and XHANCE net revenue remains uncertain and it has and is likelycould in the future continue to affect our ability to remain in compliance with ourthe financial covenant to achieve certain minimum trailing twelve month consolidated XHANCE net product sales and royalties and other covenants under that certain Note Purchase Agreement dated as of September 12, 2019 as amended pursuant to that certain letter agreement dated as of August 13, 2020 and as further amended by that certain First Amendment to Note Purchase Agreement dated as of March 2, 2021 (the Note Purchase Agreement) that we entered into with funds managed by Pharmakon Advisors, LP (Pharmakon), the investment manager of the BioPharma Credit

Due to the impacts of the COVID-19 pandemic, one of our contract manufacturers implemented a reduced work schedule and additional precautions which resulted in delays in the manufacture of XHANCE in second quarter 2020 but did not result in an interruption to commercial or clinical supply. We believe we are maintaining appropriate levels of finished product inventories in the event of future supply disruption; however, the duration and magnitude of a future negative impact from the COVID-19 pandemic could constrain our supply of XHANCE.
Previous guidance related to the expected timing of results fromFor subjects participating in our two ongoing chronic sinusitis clinical trials, indicated that top-line results from both trials would be available in the second half of 2021. Pauses in patient enrollment due to factors related to the COVID-19 pandemic have had, and may continue to have, varying effects in different geographies and over time have led to a change in our projected timeline for initial data availability and may lead to additional changes in the future. We completed enrollment in the first of our ongoing chronic sinusitis clinical trials in July 2021 and expect top-line results in the first quarter of 2022. We completed enrollment of subjects in our second clinical trial for chronic sinusitis in October of 2021 and expect top-line results in the second quarter of 2022. For those subjects currently participating in these studies, procedures to facilitate ongoing treatment and capture of data during periods of in-person care restrictions have beenwere put in place. Pauses in patient enrollment due to factors related to the COVID-19 pandemic had varying effects in different geographies which resulted in delays and additional costs associated with our chronic sinusitis trials.
The full impact of the COVID-19 pandemic including the potential for and emergence of different strains of the virus, on our business is still unknown. The COVID-19 pandemicIt is likely to continue to have adverse impacts on XHANCE prescription growth and XHANCE net revenues growth for the remainder of 2021 and into 20222 as a result of fewer patients visiting physician offices, the restrictions imposed on the logistics and restrictionsfrequency of territory managers' visits becoming permanent in some physician offices, changes in employment that can adversely affect availability of insurance coverage of XHANCE, our ability to maintain compliance with the financial and limitations imposed by physicians' offices on territory manager visits, continued high unemployment adversely affecting demandother covenants under the Note Purchase Agreement, and payor mix, and on the availability and cost of capital for us to fund our business operations and service our debt. We will continue to assess the evolving impact of the COVID-19 pandemic and will make adjustments to our operations as necessary.

XHANCE Business Update
We track and report metrics that we believe are an important part of assessing our progress in key strategic areas including:
XHANCE Prescriptions and Market Share. Based on third-party prescription data as well as data from PPN partners, the total estimated number of XHANCE prescriptions in the third quarter of 20212022 was 86,300,86,600, which represents 25%0.3% growth for prescriptions when compared to estimated third quarter 20202021 prescriptions of 69,000.86,300. The INS prescription market increased 4%1% from third quarter 20202021 to third quarter 20212022 based on third-party prescription data. In addition, the total estimated number of XHANCE prescriptions was 73,90093,700 in the fourth quarter of 2020, 72,6002021, 80,600 in the first quarter of 20212022, and 82,90087,600 in the second quarter of 2022. The decrease of prescriptions from fourth quarter 2021 to first quarter 2022 was primarily driven by changes to our co-pay assistance program in January 2022 intended to increase average net revenue per prescription by decreasing the proportion of prescriptions filled by patients with insurance coverage that required co-pays above a target threshold as well as by seasonal factors as described below. In addition, the total estimated number of XHANCE prescriptions for the nine months ended September 30, 2022, was 254,700, which represents 5% growth for prescriptions when compared to prescriptions of 241,900 for the nine months ended September 30, 2021. The INS prescription market increased 4% from the nine months ended September 30, 2021 to the nine months ended September 30, 2022 based on third-party prescription data.
A seasonal effect has historically been observed in the INS prescription market in which market volume generally peaks near the middle of the second quarter and declines into the early part of the third quarter of each calendar year. As the result of the COVID-19 pandemic, the market volume peak and subsequent declines did not follow the normal trends in 2020. Based on third-party prescription data, INS market prescriptions increased 7% from the fourth quarter of 2019 to the first quarter of 2020, decreased 16% from the first quarter of 2020 to the second quarter of 2020, decreased 6% from the second quarter of 2020 to the third quarter of 2020, increased 3% from the third quarter of 2020 to the fourth quarter of 2020, decreased 4% from fourth quarter 2020 to the first quarter of 2021, increased 14% from the first quarter of 2021 to the second quarter of 2021, and decreased 4% from the second quarter of 2021 to the third quarter of 2021.

2021 to the first quarter of 2022, increased 7% from the first quarter of 2022 to the second quarter 2022, and decreased 7% from the second quarter of 2022 to the third quarter 2022.
Although the underlying disease that we are treating is chronic and causes symptoms year-round, we believe the variation in patient flow through the offices of relevant physician specialists, and seasonality in disease flare-ups, has an impact on the number of patients that present themselves and who are therefore available to receive a new prescription for XHANCE. Demand has historically been, and we expect will continue to be, impacted by the INS market seasonality and the seasonal variation in patient visits with their doctor, resulting in reduced XHANCE prescription demand in the third quarter.
22

Table of Contents
Additionally, we believe that first quarter prescription demand and average net revenue per prescription for XHANCE is adversely impacted by the annual resetting of patient healthcare insurance plan deductibles and changes in individual patients' healthcare insurance coverage, both of which often occur in January.
We track the market share of XHANCE within our current target audience. For this purpose, we calculate market share as the proportion of XHANCE prescriptions to the number of prescriptions written for other INS within our current target audience of approximately 18,00021,000 physicians. Our target physician audience includes all ENT and allergyAllergy specialist physicians who, based on third-party data, write intranasal steroid spray prescriptions. In addition, our current target audience includes specialty-like primary care physicians called on by our territory managers or kaléo sales representatives. Prior to the fourth quarter 2020 initiation of XHANCE co-promotion by kaléo, our target audience included approximately 10,000 physicians called on by Optinose sales territory managers. We have mutually agreed to terminate our co-promotion agreement with kaléo as of December 31, 2021.
We believe market share, in addition to XHANCE prescription volume, provides important information regarding XHANCE utilization because market share normalizes XHANCE prescriptions for market effects including the INS market seasonality, seasonal variation in patient visits with their doctor, annual deductible resets and annual changes in individual patient's healthcare insurance coverage referenced above. Based on third-party prescription data as well as data from PPN partners, we estimate XHANCE had a market share in our current target audience of 18,00021,000 physicians of 4.9% in the third quarter of 2020, 5.1%4.8% in the fourth quarter of 2020, 5.0% in the first quarter of 2021, 5.2% in the second quarter of 2021, 5.7% in the third quarter of 2021, 5.9% in the fourth quarter of 2021, 5.4% in the first quarter of 2021, 5.4%2022, 5.6% in the second quarter of 20212022, and 6.0%5.7% in the third quarter of 2021.2022. Note that most of the INS prescriptions written within our target physician audience are for chronic sinusitis, allergic rhinitis and other conditions outside of our nasal polyp indication. Our target physician audience is subject to revision each quarter to account for changes such as revised sales target prioritization, and physician retirements. Changes to the target physician audience can contribute to some of the quarter-over-quarter change in market share.
XHANCE New Prescriptions and Refill Prescriptions. The underlying disease that we are treating is chronic and, as a result, many patients may fill multiple prescriptions per year. We monitor new prescriptions as they create the potential for future refill prescriptions. Based on third-party prescription data as well as data from PPN partners, the total estimated number of XHANCE new prescriptions in the third quarter of 20212022 was 27,900,28,000, which represents 22%0.2% growth for new prescriptions when compared to estimated third quarter 20202021 new prescriptions of 23,000.27,900. In addition, the total estimated number of XHANCE new prescriptions was 24,60029,900 in the fourth quarter of 2020, 25,9002021, 28,200 in the first quarter of 20212022, and 29,00029,200 in the second quarter of 2021.2022. Based on third-party prescription data, the INS market for new prescriptions increased 9%1% from the third quarter of 2020 to the third quarter of 2021 and decreased 4% from the second quarter of 2021 to the third quarter of 2022 and decreased 10% from the second quarter of 2022 to the third quarter of 2022. In addition, the total estimated number of XHANCE new prescriptions for the nine months ended September 30, 2022, was 85,400, which represents 3% growth for new prescriptions when compared to new prescriptions of 82,900 from the nine months ended September 30, 2021. The INS market for new prescriptions increased 8% for the nine months ended September 30, 2021 to the nine months ended September 30, 2022 based on third-party prescription data.
We track refill prescriptions and provide patient assistance to support refill programs that are administered by our PPN partners. Based on third-party prescription data as well as data from PPN partners, the total estimated number of XHANCE refill prescriptions in the third quarter of 20212022 was 58,400,58,600, which represents 27%0.3% growth for refill prescriptions when compared to estimated thirdsecond quarter 20202021 refill prescriptions of 46,100.58,400. In addition, the total estimated number of XHANCE refill prescriptions was 49,30063,800 in the fourth quarter of 2020, 46,7002021, 52,400 in the first quarter of 20212022, and 53,90058,400 in the second quarter of 2021.2022.
Prescribing Breadth and Depth. We track the number of physicians who prescribe XHANCE in a time period to evaluate the breadth of prescribing. Based on third-party prescription data as well as data from PPN partners, the total estimated number of physicians who had at least one patient fill a prescription for XHANCE in the third quarter of 20212022 was 7,196,7,892, which represents 12%10% growth when compared to the estimated 6,4437,196 physicians who had at least one patient fill a prescription for XHANCE in the third quarter of 2020.2021. In addition, the total estimated number of physicians who had at least one patient fill a prescription for XHANCE was 6,7087,532 in the fourth quarter of 2020, 6,9202021, 7,690 in the first quarter of 20212022, and 7,1887,851 in the second quarter of 2021.2022.

We also track the number of prescriptions filled by a prescribing physician's patients in a time period to evaluate depth of prescribing. Based on third-party prescription data as well as data from PPN partners, the total estimated number of physicians who had more than 15 XHANCE prescriptions filled by their patients in the third quarter of 20212022 was 1,459,1,491, which represents 27%2% growth when compared to the estimated 1,1531,459 physicians who had more than 15 XHANCE prescriptions filled by their patients in the third quarter of 2020. 2021.

In addition, the total estimated number of physicians who had more than 15 XHANCE prescriptions filled by their patients was 1,2751,589 in the fourth quarter of 2020, 1,2852021, and 1,468 in the first quarter of 20212022, and 1,4141,500 in the second quarter of 2021.2022.
XHANCE Net Product Revenues per Prescription. We calculate average net product revenues per prescription, one metric that we use to gauge the profitability of XHANCE, by dividing net product revenues for the quarter by the estimated number of XHANCE prescriptions dispensed during the quarter. Average XHANCE net product revenues per prescription were $253$232 in the third quarter of 20212022 which represents an approximately 13% increase8% decrease when compared to the $224$253 average XHANCE net product revenues per prescription in the third quarter of 2020.2021. This decrease was primarily driven by a one-time refund of disputed rebates in third quarter of 2021. This decrease was partially offset by changes to our co-pay assistance program in January 2022 intended to increase average net revenue per prescription by decreasing the proportion of prescriptions filled by patients with insurance coverage that required co-pays above a target threshold. In addition, average XHANCE net revenues per prescription were $211$240 in the fourth quarter of 2020, $1512021, $183 in the first quarter of 20212022, and $221$235 in the second quarter of 2022. Average XHANCE net product revenues per prescription were $218 for the nine months ended September 30, 2022 which represents an approximately 3% increase when compared to the $211 average XHANCE net product revenues per prescription for the nine months ended September 30, 2021.
Sales, Marketing & Distribution
We have established a commercial infrastructure designed to drive adoption and sales of XHANCE with healthcare professionals who treat patients with nasal polyps. We believe that approximately 15,000 physicians treat an estimated 3.5 million chronic rhinosinusitis patients, an estimated 1.2 million of whom have chronic rhinosinusitis with nasal polyps.
Customer Model.  We have a sales force of approximately 10090 territory managers who target over 10,000 ENTs, allergists and “specialty-like” primary care physicians, and we target additional physicians through digital and non-personal promotion in areas where we do and do not have territory managers. In addition, we initiated a co-promotion agreement with kaléo in October 2020 to promote XHANCE to an audience of up to 6,000 prescribers, about half of whom are outside of our current called-on universe. Our sales team and the sales team of our co-promotion partner, areis equipped with educational materials demonstrating the benefit and safety profile of XHANCE. We believe the restrictions imposed on the logistics and frequency of territory managers' visits during the COVID-19 pandemic have mutually agreed to terminatenow become permanent in some physician offices which is adversely impacting the effectiveness of our co-promotion agreement with kaléo assales force. If we successfully obtain a follow-on indication for XHANCE for the treatment of December 31, 2021. We believe thatchronic sinusitis, we may in the long term,future increase the number of geographic territories as well as hire additional territory managers in order to increase the number of called-on target physicians and frequency of calls. In addition, we believe direct-to-consumer (DTC) advertising could be an effective way to increase XHANCE prescription growth.growth in the future with a follow-on indication for chronic sinusitis.

XHANCE Co-Pay Savings Program. We believe our co-pay savings program provides an affordability solution for patients that physicians will support. This program provides patient co-pay assistance including a first prescriptionto eligible commercially insured patients. These patients may obtain XHANCE for as little as no out-of-pocket cost ($0 co-pay) to eligible commercially insured patients and low subsequent co-pays for refills ranging from $0 to $50 per XHANCE unit.out-of-pocket.

Market Access.  Based on currently available third-party data and our internal analyses as of September 30, 2021,October 1, 2022, we believe that greater than 75%approximately 80% of commercially insured lives are currently in a plan that covers XHANCE. However, payors may change coverage levels for XHANCE, positively or negatively, at any time. Additionally, payors generally impose restrictions on access to or usage of XHANCE, such as by requiring prior authorizations or "step-edits". For example, insurers may require that a physician attest that they are treating a patient first use a generic INSfor an approved indication prior to becoming eligible for coverage for XHANCE. SomeWe estimate that approximately half of the commercially covered lives as of October 1, 2022 are in a plan that requires a prior authorization and most of those prior authorizations request information regarding prior use of INS and a patient diagnosis of nasal polyps. In some cases, patients do not meet the payors' utilization management criteria, and in other cases, healthcare providers may not complete the administrative process required to demonstrate or document that the patients for whom XHANCE has been prescribed meet the payors’ utilization management criteria (i.e., prior authorizations or step-edits) and, as a result, patients may not gain access to XHANCE treatment. In our contract negotiations with payors we seek to balance patient access and affordability, breadth of coverage, payor utilization management and rebates levels. We have also contracted with the Centers for Medicare and Medicaid Services for coverage of certain government insured lives and continue to expand XHANCE market access for other government-insured populations.

Trade and Distribution We currently sell XHANCE primarily to PPN partners. We established this channel to offer patients the option of filling prescriptions through a network of preferred pharmacies that may be able to better serve the needs of patients through services including delivery of XHANCE by mail and performing certain patient services such as patient insurance benefit verification. We also sell XHANCE to wholesale pharmaceutical distributors, who, in turn, sell XHANCE to retail pharmacies, hospitals and other customers. We have contracted with a third-party logistics provider for key services related to logistics, warehousing and inventory management, and distribution. Further, our third-party logistics provider provides customer order fulfillment services and accounts receivable management.

XHANCE Development
In addition to XHANCE’s existing indication for the treatment of nasal polyps, in order to broaden our U.S. market opportunity, we initiated a clinical trial program in pursuit of a follow-on indication for the treatment of chronic sinusitis.sinusitis in the U.S. We believe XHANCE has the potential to be the first drug therapy approved by the FDA for the treatment of chronic sinusitis. We expect the program will be comprised of two Phase 3b clinical trials, the first of which, ReOpen1, was initiated in the fourth quarter of 2018, and completed enrollment of approximately 330 subjectschronic sinusitis patients with and without nasal polyps in July of 2021, and the2021. The second of whichtrial, ReOpen2, was initiated in the second quarter of 2019 and completed enrollment of approximately 210 subjects220 chronic sinusitis patients without nasal polyps in October of 2021.
We announced positive top-line results for ReOpen1 and ReOpen2 in March and June 2022, respectively. In April 2021,September 2022, we completedmet with the FDA to discuss our planned supplemental new drug application for XHANCE as a previously planned, blinded interim analysistreatment for adults with chronic sinusitis and plan to assesssubmit the variance in one of the two co-primary endpoints (change in Composite Score of Nasal Symptoms from baseline to week 4) in our first clinical trial for chronic sinusitis. The analysis was performed on blinded interim data from approximately half of the initial estimated enrollment of 378 patients. The result of this interim analysis was that the observed variance in this endpoint was lower than the variance assumed when we estimated sample size for statistical powering during the initial design of the trial.
In June 2021, we completed a previously planned, blinded interim analysis to assess the variance in the other co-primary endpoint (change in average percent opacification of volume by CT scan from baseline to week 24) in this trial. The analysis was performed on blinded interim data from approximately one-third of the initial estimated enrollment of 378 patients for whom 6-month CT scan data was available. The result of this interim analysis was that the observed variance in this endpoint was also lower than the variance assumed when we estimated sample size for statistical powering during the initial design of the study. Based on the results of these two interim analyses, and our assumptions and estimates relatingapplication to the trial, we anticipate that the initial targeted statistical power will be achieved with the approximately 330 patients currently enrolledFDA in the trial.early 2023.

For clarity, all of these interim analyses were blinded to treatment group and therefore could not evaluate the magnitude of difference, if any, between treatment groups.Accordingly, these interim analyses were not designed to, and do not, provide evidence regarding possible superiority of active treatment over placebo or success of the trials.

We expect top-line results from the first of our two ongoing Phase 3b chronic sinusitis clinical trials in the first quarter of 2022 and from the second clinical trial in the second quarter of 2022.

OPN-019 Development Update
In June 2020, we announced the initiation of development of a new product candidate, OPN-019, which combines our proprietary intranasal Exhalation Delivery System (EDS) device with an antiseptic.

We have performed in vitro testing against SARS-CoV-2 with a candidate formulation in which a 4-log reduction (a 99.99% reduction) in virus count was produced. In addition, we performed tests against other pathogens. For most pathogens tested, 3-log to 6-log reductions (99.9% to 99.9999% reductions) in virus count were observed.

In July 2021, we received approval from regulatory authorities in Mexico to conduct a randomized, proof-of-concept trial in Mexico in subjects who have tested positive for SARS-CoV-2 infection, who were recently infected, and who have mild or no symptoms. The trial is intended to evaluate both the magnitude and duration of viral load reduction after a single dose of OPN-019. Recruitment in this trial is currently paused while specimen-handling and laboratory procedures in Mexico undergo further evaluation.

Should proof-of-concept data suggest benefits, we expect to use the data to support pursuit of grants, partnerships, and/or other sources of capital that would be necessary to fund future development of OPN-019.

Financial Operations Overview
The following discussion sets forth certain components of our consolidated statements of operations as well as factors that impact those items.
Net product revenues
Sales of XHANCE generated $21.8$20.1 million and $15.4$21.8 million in net product revenues for the three months ended September 30, 20212022 and 2020,2021, respectively, and $51.1$55.4 million and $32.8$51.1 million for the nine months ended September 30, 20212022 and 2020,2021, respectively. In accordance with GAAP, we determine net product revenues for XHANCE, with specific assumptions for variable consideration components including but not limited to trade discounts and allowances, co-pay assistance programs and payor rebates.
Based on available XHANCE prescription data purchased from third parties and data from our PPN partners, who collectively dispensed more than 85%80% of our total prescriptions (TRxs) in the period, our average net product revenues per prescription for the secondthird quarter of 20212022 was $232, a decrease compared to average net product revenues per prescription of $253 in the third quarter of 2021. In addition, our average net product revenues per prescription for the nine months ended September 30, 2022 was $218, an increase compared to average net product revenues per prescription of $221 in second quarter of$211 for the nine months ended September 30, 2021 and an increase compared to $224 in the third quarter of 2020.
The increase in average net product revenues per prescription from the second quarter of 2021 to the third quarter of 2021 is a consequence of reduced co-pay support under our assistance programs as the result of patients' meeting their out-of-pocket expense thresholds and the effect of reduced rebate rates, including a one-time refund of disputed rebates.
The increasedecrease in average net product revenues per prescription from the third quarter of 20202021 to the third quarter of 2022 is primarily the result of a one-time refund of disputed rebates that occurred in the third quarter of 2021.

The increase in average net product revenues per prescription for the nine months ended September 30, 2022 compared to the nine months ended September 30, 2021 is driven largely by changes in 20212022 to our co-pay assistance planprogram that were intended to increase revenues per prescription by reducingdecreasing the rateproportion of growthprescriptions filled by patients with insurance coverage that required co-pays above a target threshold. This is offset in prescription fillspart by commercially insured patients in plans that do not cover XHANCE, while sustaining growth in covered plans, as well as the absence of a one-time co-pay assistance program that was available to new patientsan increase in the second quarterproportion of 2020.volumes attributable to government programs including Medicare and Medicaid which have a lower average net revenue per prescription than commercial insurance prescriptions because of higher rebates that we are required to pay under such government programs.
We calculate average net product revenues per prescription, one metric that we use to gauge the profitability of XHANCE, by dividing net product revenues for the quarter by the estimated number of XHANCE prescriptions dispensed during the quarter. As a result, average net product revenues per prescription is subject to variability. That variability is impacted by factors that do not necessarily reflect a change in the price that is paid for an individual unit of XHANCE, including but not limited to ordering patterns and inventory levels for our wholesale customers and PPN partners, patient utilization rates of affordability programs and the proportion of patients acquiring XHANCE through an insurance benefit. There is also the potential for variability that results from changes in estimation methodology by the third parties that we rely upon to provide prescription data which may lead to revisions of historical estimates of prescription volumes and our calculated average net product revenues per prescription.
We expect full year 20212022 net product revenues towill be $71.0 to $75.0between $74.0 million and $78.0 million. Previously we expected full year 20212022 net product revenues towould be at least $80between $85.0 million and $92.0 million. The reductionWe revised our full year 2022 guidance for net revenue because of an anticipated increase in our net product revenue expectations for 2021XHANCE demand driven by the fall allergy season (which is primarily the resultrebound that historically occurs in the INS prescription market after hitting its low in the early part of the continuing adverse impactthird quarter), new promotional materials including exacerbation data from the ReOpen program and other commercial initiatives have not materialized through the date of filing of this report. As a result, we have removed the COVID-19 pandemic onexpectation of this additional XHANCE prescriptiondemand and the associated refills from our projections for the remainder of 2022. Although we believe that physician interest in prescribing XHANCE, net product revenue growth rates.
and actual writing of XHANCE, continues to grow, we believe payer constraints, especially for off-label indications, is decreasing the proportion of written prescriptions being filled. We expect full year 2022 average net product revenues per prescription for the full year of 2021 will exceed $210.be approximately $220. Previously we expected full year 20212022 average net product revenues per prescription to be greater than $200. Factors supporting this expected growth include patients meeting their out-of-pocket expense thresholds, expected improvements in insurance coverage and continued strength in the proportion of prescription refills.

The duration and magnitude of the negative impact from the COVID-19 pandemic has, and is likely to continue to, affect our ability to remain in compliance with certain of the financial covenants in the Note Purchase Agreement, including the requirement to achieve at least $80.0 million in consolidated XHANCE net product sales and royalties for the trailing twelve-month period ending December 31, 2021. If we do not achieve $80.0 million in consolidated XHANCE net product sales and royalties for the trailing twelve-month period ending December 31, 2021 and we are unable to obtain a waiver or modification to this financial covenant, we will be in breach of a financial covenant of the Note Purchase Agreement, which will constitute an event of default under the terms of the Note Purchase Agreement. If the holders of the notes issued pursuant to the Note Purchase Agreement (the Pharmakon Senior Secured Notes) elect to accelerate the repayment of all unpaid principal and accrued interest under such holders’ Pharmakon Senior Secured Notes, we may need to delay or curtail our operations. Our assets or cash flow may not be sufficient to fully repay our obligations under the Note Purchase Agreement if the obligations thereunder are accelerated upon any events of default.$220.
Licensing revenues
In September 2019, OptiNose AS, a wholly owned subsidiary of the Company, entered into the Currax License Agreement. Under the terms of the Currax License Agreement, Currax paid us a $3.7 million upfront payment in 2019, an additional $0.8 million in December 2020 upon expiration of the escrow that was established for a limited period to cover potential indemnification obligations, and an additional $1.0 million milestone payment in January 2021 upon the achievement of a specified regulatory milestone. We are not eligible to receive any further payments from Currax under the terms of the Currax License Agreement other than reimbursement for certain expenses.
Costs of product sales
Costs of product sales includes the cost of inventory sold, which includes direct and indirect manufacturing and supply chain costs.
Research and development expense
Research and development expense consists primarily of expenses incurred to prepare for, initiate and conduct our planned clinical trials, ongoing research efforts of new products and device improvements. We expense research and development costs as incurred. These expenses include:
personnel expenses, including salaries, benefits and stock-based compensation expense;
costs of funding clinical development performed by third parties, including pursuant to agreements with contract research organizations (CROs), as well as investigative sites and consultants that conduct or support our nonclinical studies and clinical trials;
expenses associated with the continued development of our EDS devices;the EDS;
expenses incurred under agreements with contract manufacturing organizations (CMOs), including manufacturing scale-up expenses prior to regulatory approval of products for commercial sale and the cost of acquiring and manufacturing preclinical study and clinical trial materials;

consultant fees and expenses associated with outsourced professional scientific development services;
expenses for regulatory activities, including filing fees paid to regulatory agencies and costs incurred to compile and respond to filings with the FDA prior to regulatory approval of products for commercial sale; and
allocated expenses for facility costs, including rent, utilities, depreciation and maintenance.
We typically use our employee, consultant and infrastructure resources across our research and development programs. Although we track certain outsourced development costs by product candidate, we do not allocate personnel costs or other internal costs to specific product candidates.
We plan to incur research and development expenses as we continue the development of XHANCE for the treatment of chronic sinusitis and our other product candidates. Clinical trial costs associated with our chronic sinusitis program represent a substantial portion of our total research and development expenses. While we would expect to continue to incur regulatory and other development expenses after the conclusion of our chronic sinusitis clinical program, we expect the costs associated with the conduct of clinical trials to significantly decrease. Due to the inherently unpredictable nature of clinical development, compounded by the uncertainty introduced by the COVID-19 pandemic, the rate of subject enrollment, number of subjects required, and trial duration and outcome,
27

Table of Contents
there is uncertainty as to the exact timing of when we expect our research and development costs related to the clinical development of XHANCE to significantly decrease.
Selling, general and administrative expense
General and administrative expense consists primarily of personnel expenses, including salaries, benefits and stock-based compensation expense, for employees in executive, finance, accounting, business development, information technology, legal and human resource functions. General and administrative expense also includes corporate facility costs, including rent, utilities, depreciation and maintenance, not otherwise included in research and development expense, as well as regulatory fees and professional fees for legal, patent, accounting and other consulting services.
Sales and marketing expenses include our sales team and supporting promotional materials, digital promotion, peer-to-peer education, congresses / conventions, samples, and marketing activities targeted towards health care providers, payors and patients/consumers, including initiatives and fees related to our co-promotion efforts. Additionally, sales and marketing-related expenses include fees paid to our PPN partners for services unrelated to traditional distribution functions, such as data fees and benefit claims adjudication and other enhanced services performed as part of our PPN.adjudication.
Interest (income) expense
Interest (income) expense consists of interest earned on our cash and cash equivalents held with institutional banks and interest expense is primarily related to the Note Purchase Agreement.
Other (income) expense
Other (income) expense consists primarily of foreign currency (income) losses due to exchange rate fluctuations on transactions denominated in a currency other than our functional currency.

Senior Secured Note Purchase Agreement
On September 12, 2019 (the Closing Date), we entered into thea Note Purchase Agreement (the Note Purchase Agreement) with funds managed by Pharmakon Advisors, LP (Pharmakon), the investment manager of BioPharma.BioPharma Credit Funds (BioPharma). The Note Purchase Agreement, as amended, provided us, through our subsidiary OptiNose US, Inc., with $130.0 million in debt financing, of which $80.0 million of Pharmakon Senior Secured Notes was issued on the Closing Date, $30.0 million was issued on February 13, 2020 after achieving the $9.0 million consolidated XHANCE net sales and royalties threshold for the quarter ended December 31, 2019 and $20.0 million was issued on December 1, 2020.

On August 13, 2020 we entered into a letter agreement (the Pharmakon Letter Agreement) toafter achieving the Note Purchase Agreement. The Pharmakon Letter Agreement provided us with the option to issue additional Pharmakon Senior Secured Notes, subject to us achieving specified$14.5 million consolidated XHANCE net sales and royalties threshold for the quarter ended JuneSeptember 30, 2021 and certain other conditions. As consideration for2020.
Amounts outstanding under the Pharmakon Letter Agreement, we issued 44,643 shares of Common Stock to Pharmakon. The aggregate fair value of $250,000 was recorded as debt issuance costs and is being amortized to interest expense over the five-year term of the Pharmakon Senior Secured Notes. We are no longer eligible for the additional Pharmakon Senior Secured Notes as the requisite conditions were not satisfied as of June 30, 2021.
On March 2, 2021, we entered into the first amendment (the First Amendment) to the Note Purchase Agreement. The First Amendment revised certain minimum trailing twelve-month consolidated XHANCE net sales and royalties we are required to achieve. As consideration for the First Amendment, we will pay an amendment fee of $1.3 million upon the earlier of the prepayment of the Pharmakon Senior Secured Notes and September 12, 2024.
The Pharmakon Senior Secured Notes bear interest at a fixed per annum rate of 10.75% per annum and are scheduled to mature on September 12, 2024 (the Maturity Date). We are required to make interest-only payments on the Pharmakon Senior Secured Notes until September 2023. Principal repayments will commence on September 15, 2023, with five equal quarterly installments of principal and interest payments untilthrough to the Maturity Date. We areUpon repayment of the Senior Secured Notes we will also be required to make principal payments, which are payablepay $3.4 million in eight equal quarterly installments beginning on December 15, 2022 and continuing until the Maturity Date; provided that we may, at our election, postpone any such principal payment until the Maturity Date if, as of the applicable payment date, certain minimum trailing four-quarter consolidated XHANCE net sales and royalties thresholds have been achieved.

We are required to repay the Pharmakon Senior Secured Notes in full upon the occurrence of a change of control (as defined in the Note Purchase Agreement). In addition, we may make voluntary prepayments in whole or in part. All mandatory and voluntary prepayments are subject to the payment of prepayment premiums as follows: (i) if prepayment occurs prior to the third anniversary of the Closing Date, an amount equal to 2% of the principal prepaid, (ii) if prepayment occurs on or after the third anniversary of the Closing Date but prior to the fourth anniversary of the Closing Date, an amount equal to 1% of the principal prepaid;prepaid, and (iii) if prepayment occurs on or after the fourth anniversary of the Closing Date, no prepayment premium is required.

The Pharmakon Senior Secured Notes are secured by a pledge of substantially all of our assets and the Note Purchase Agreement contains affirmative and negative covenants customary for financings of this type, including limitations on our and our subsidiaries’ ability, among other things, to incur additional debt, grant or permit additional liens, make investments and acquisitions, merge or consolidate with others, dispose of assets, grant certain license rights to our products, technologies and other intellectual property rights; pay dividends and distributions, repay junior indebtedness and enter into affiliate transactions, in each case, subject to certain exceptions. In addition, the Note Purchase Agreement contains financial covenants requiring us to maintain at least $30.0 million of cash and cash equivalents.equivalents at all times and requiring us to achieve certain minimum trailing twelve-month consolidated XHANCE net sales and royalties, tested on a quarterly basis, as follows (in millions):

On August 10, 2022, we entered into a Third Amendment to the Note Purchase Agreement to reduce the minimum consolidated XHANCE net sales and royalties required to be achieved for the trailing twelve-month period ending December 31, 2022 from $90.0 million to $85.0 million in exchange for a $0.8 million fee due on the repayment of the Pharmakon Senior Secured Notes.
On November 9, 2022, we entered into a Fourth Amendment to the Note Purchase Agreement to obtain a waiver of the minimum consolidated XHANCE net sales and royalties required to be achieved for the trailing twelve-month period ending September 30, 2022 and December 31, 2022 in exchange for a $1.3 million fee due on the repayment of the Pharmakon Senior Secured Notes.
We believe that it is probable we will not achieve the trailing twelve-month minimum consolidated XHANCE net sales and royalties that we are required to achieve under the Note Purchase Agreement for the periods ending March 31, 2023, June 30, 2023, and September 30, 2023, which will constitute a default of this financial covenant under the Note Purchase Agreement if we are unable to obtain a modification or waiver of such minimum consolidated XHANCE net sales and royalties thresholds. Additionally, we believe it is probable that our existing cash and cash equivalents will not be sufficient to maintain at least $30,000 of cash and cash equivalents for at least twelve-months following the filing of this Form 10-Q, which will constitute a default of this liquidity financial covenant under the Note Purchase Agreement if we are unable to obtain additional capital or a modification or waiver of such covenant prior to falling below such $30,000 threshold. In the event that any one of the foregoing defaults were to occur, the holders of the Pharmakon Senior Secured Notes may declare an event of default under Note Purchase Agreement and may elect to accelerate the repayment of all unpaid principal, accrued interest and other amounts due under such holders’ Pharmakon Senior Secured Notes. As a result, in accordance with FASB Accounting Standards Codification 470, we have classified all outstanding principal and the payment of additional fees upon maturity as a current liability in the accompanying consolidated balance sheet as of September 30, 2022.
The Note Purchase Agreement also includes other events of default customary for debt financings of this type, in certain cases subject to customary periods to cure, following which BioPharma may accelerate all amounts outstanding under the Pharmakon Senior Secured Notes.Notes

Projected 20212022 operating expenses
We expect that our total GAAP operating expenses (consisting of selling, general & administrative expenses and research & development expenses) for 20212022 will be between $132.0$127.0 million and $137.0$131.0 million of which approximately $10.0$9.0 million is expected to be non-cash stock-based compensation expense. As a result, total GAAP operating expenses excluding non-cash stock-based compensation expense are expected to be between $122.0$118.0 million and $127.0$122.0 million. An increase inPreviously we expected total GAAP operating expenses for 2022 to be between $129.0 million and $134.0 million of which approximately $9.0 million was expected to be stock-based compensation expense. We expect operating expenses to remain relatively consistent from 20202021 to 2021 is anticipated2022, primarily due primarily to an increase in fees paid to our PPN partners associated with higher projected XHANCE prescription volumes and an increaseexpected decrease in research and development expenses related toas our clinical trial program in pursuit of a follow-on indication for XHANCE for the treatment of chronic sinusitis.sinusitis nears completion, which is expected to be offset by an increase in sales, marketing, and other patient assistance costs. In addition, we expect total GAAP operating expenses for 2023 to decrease materially when compared to 2022 operating expenses. Research and development expenses will decrease as a result of the chronic sinusitis clinical trial program concluding and we plan to reduce selling, general & administrative expenses through operational and promotional efficiencies while continuing to well position XHANCE for a CS launch, if approved.
Future fundingcapital requirements
We expect to continue to incur significant expenses in connection with our ongoing activities, particularly as we:
maintain our sales force and the commercial infrastructure to support the sales and marketing for XHANCE;
continue advertising and other promotional activities to support the commercialization of XHANCE;
continue to provide co-pay and other patient affordability programs;programs for XHANCE;

maintain infrastructure necessary to operate as a publicly-traded, FDA-regulated commercial-stage company; and
hire additional staff and add operational, financial and information systems to execute our business plan.
Our future fundingcapital requirements, both near and long-term, will depend on many factors, including, but not limited to:
the duration and impact of the COVID-19 pandemic on our business;
the success of our commercialization of XHANCE for the treatment of nasal polyps including, among other things, continued patient and physician acceptanceadoption of XHANCE and our ability to maintain adequate insurance coverage and reimbursement for XHANCE;

Although it is difficult to predict our future liquidity requirements, weAs of September 30, 2022, we had $61.1 million in cash and cash equivalents. We will likely require additional capital in the future securednear term in order to maintain compliance with the financial covenants and other terms under the Note Purchase Agreement and to meet the debt service obligations under our outstanding Pharmakon Senior Secured Notes and to continue to fund our operations.
Our continuation as a going concern is dependent on our ability to maintain compliance with the financial covenants and other terms under the Note Purchase Agreement, and our ability to generate sufficient cash flows from operations and/or obtain additional capital through equity or debt financings, partnerships, collaborations, or other sources in order to meet the debt service obligations under our outstanding Pharmakon Senior Secured Notes, including repayment, and to carry out our planned developmentlong-term business strategy.
On November 9, 2022, we entered into a Fourth Amendment to the Note Purchase Agreement to obtain a waiver of the minimum consolidated XHANCE net sales and commercial activities.royalties required to be achieved under the Note Purchase Agreement for the trailing twelve-month period ending September 30, 2022 and December 31, 2022 in exchange for a $1.3 million fee due on the repayment of the Pharmakon Senior Secured Notes. We believe it is probable that we will not achieve the trailing twelve-month minimum consolidated XHANCE net sales and royalties thresholds that we are required to achieve under the Note Purchase Agreement for the periods ending March 31, 2023, June 30, 2023 and September 30, 2023, which will constitute a default under the Note Purchase Agreement if we are unable to obtain a modification or waiver of such minimum consolidated XHANCE net sales and royalties thresholds. In addition, we believe that it is probable that our existing cash and cash equivalents will not be sufficient to maintain the minimumat least $30.0 million of cash balanceand cash equivalents as required under the Note Purchase Agreement and to fund our operations for at least twelve months fromtwelve-months following the filing date of this Quarterly Report on Form 10-Q, which will constitute a default of the liquidity financial covenant under the Note Purchase Agreement if inwe are unable to obtain additional capital or obtain a waiver or modification to this liquidity covenant prior to falling below such $30.0 million threshold. In the event of a default,any one of the foregoing defaults were to occur, the holders of the Pharmakon Senior Secured Notes do notmay declare an event of default under Note Purchase Agreement and may elect to accelerate the repayment of all unpaid principal, and accrued interest and other amounts due under such holders’ Pharmakon Senior Secured Notes.
The holders of the Pharmakon Senior Secured Notes have, in the past, conditioned modifications to the minimum trailing twelve-month consolidated XHANCE net sales and royalties financial covenant and other provisions of the Note Purchase Agreement; however, we will likely requireAgreement on our securing additional capital through equity financings and other conditions and fees, and could do so again in the future, which would impact the timing and amount of capital that we may seek to fundraise in a financing. There can be no guarantee that the holders of the Pharmakon Senior Secured Notes will provide a waiver or modification if requested. In addition, in order to complete future financings the investors in such financings may require us to obtain certain modifications to the minimum trailing twelve-month consolidated XHANCE net sales and royalties financial covenant, liquidity financial covenant and other provisions of the Note Purchase Agreement which may or may not be acceptable to the holders of the Pharmakon Senior Secured Notes.

These factors raise substantial doubt about our ability to continue as a going concern. Additionally,If we are unable to continue as a going concern, we may failhave to liquidate our assets and may receive less than fair value for such assets and less than the value at which such assets are carried on our financial statements, and it is likely that investors will lose all or a part of their investment.

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Additionally, in designing disclosure controls and procedures, our management was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a control system, misstatements due to error or fraud may occur and not be detected.

Risks Related to Our Financial Position and Capital Resources8, 2022.

We have identified conditions and events that raise substantial doubt about our ability to continue as a going concern.

As of September 30, 2021,2022, we had cash and cash equivalents of $84.2 million.$61.1 million and have issued $130.0 million of senior secured notes (the Pharmakon Senior Secured Notes) under our Note Purchase Agreement with Pharmakon. Our accumulated deficit as of September 30, 20212022 was $594.4$669.7 million. We have incurred significant net losses since inception and also expect to incur substantial losses in future periods. Our continuation as a going concern is dependent on our ability to maintain compliance with ourthe financial covenants under that certain Note Purchase Agreement dated as of September 12, 2019, as amended pursuant to that certain letter agreement dated as of August 13, 2020 and as further amended by that certain first amendment toother terms under the Note Purchase Agreement, dated as of March 2, 2021 (the Note Purchase Agreement) that we entered into with funds managed by Pharmakon Advisors, LP (Pharmakon), the investment manager of the BioPharma Credit Funds (BioPharma) and our ability to generate sufficient cash flows from operations to meet our obligations and/or obtain additional financing from our stockholderscapital through equity or debt financings, partnerships, collaborations, or other sources as may be required.to meet the debt service obligations under our outstanding Pharmakon Senior Secured Notes, including repayment, and to carry out our planned development and commercial activities.
In March 2021,
On November 9, 2022, we entered into a Fourth Amendment to the Note Purchase Agreement was amended to revise certain covenants relating toobtain a waiver of the minimum trailing twelve-month consolidated XHANCE net sales and royalties includingrequired to be achieved under the requirement to achieve at least $80.0 millionNote Purchase Agreement for the trailing twelve-month period ending September 30, 2022 and December 31, 2021.

As2022 in exchange for a $1.3 million fee due on the repayment of the filing of this quarterly report on Form 10-Q,Pharmakon Senior Secured Notes. We believe it is probable that we expectwill not achieve the trailing twelve-month minimum consolidated XHANCE net sales and royalties thresholds that we are required to achieve under the Note Purchase Agreement for the trailing twelve-month periodperiods ending DecemberMarch 31, 20212023, June 30, 2023 and September 30, 2023, which will constitute a default under the Note Purchase Agreement if we are unable to be between $71.0 million and $75.0 million. If we do not achieve $80.0 millionobtain a modification or waiver of such minimum consolidated XHANCE net sales and royalties thresholds. In addition, the Note Purchase Agreement contains financial covenants requiring us to maintain at all times a minimum of $30.0 million of cash and cash equivalents. We believe that it is probably that our existing cash and cash equivalents will not be adequate to fund our operations and maintain at least $30.0 million of cash and cash equivalents as required under the Note Purchase Agreement for at least twelve-months following the trailing twelve-month period ending December 31, 2021 andfiling of this Form 10-Q, which will constitute a default of the liquidity financial covenant under the Note Purchase Agreement if we are unable to obtain additional capital or obtain a waiver or modification to this financialliquidity covenant we will be in breach of a financial covenantprior to falling below such $30.0 million threshold. In the event that any one of the Note Purchase Agreement asforegoing defaults defaults were to occur, the holders of December 31, 2021, which will constitutethe Pharmakon Senior Secured Notes may declare an event of default under the terms of the Note Purchase Agreement. If the holders of the senior secured notes issued pursuant to the Note Purchase Agreement (Pharmakon Senior Secured Notes)and may elect to accelerate the repayment of all unpaid principal, and accrued interest and other amounts due under such holders’ Pharmakon Senior Secured Notes, as described below, wewhich may be forcedrequire us to delay or reduce the scope ofcurtail our development programsoperations until we are able to obtain additional capital which may not be available on a timely basis, on favorable terms, or at all, and clinical trials,such capital, if obtained, may not be sufficient to meet our payment obligations or enable us to continue to implement our long-term business strategy. In such an event, our business, prospects, financial condition and results of operations will be materially and adversely affected, and we may be unable to continue as a going concern. These factors raise substantial doubt about our ability to continue as a going concern. If we are unable to continue as a going concern, we may have to liquidate our assets and may receive less than the fair value for such assets or less than the value at which those assets are carried on our financial statements, and it is likely that investors will lose all or a part of their investment. FutureAdditionally, future reports of our independent registered public accounting firm may contain statements expressing substantial doubt about our ability to continue as a going concern. If we seek additional financing to fund our debt service obligations and business activities in the future and there remains substantial doubt about our ability to continue as a going concern, investors or other financing sources may be unwilling to provide funding to us on commercially reasonable terms, if at all.


Our failure to comply with the covenants or other terms of the Note Purchase Agreement, including but not limited to as a result of events beyond our control, could result in a default under the Note Purchase Agreement that could materially and adversely affect the ongoing viability of our business.

OnAs of September 12, 201930, 2022, we have issued $130.0 million of senior secured notes (the Closing Date), we entered intoPharmakon Senior Secured Notes) under the Note Purchase Agreement that provided for the issuance of up to $150.0 million of the Pharmakon Senior Secured Notes, of which $80.0 million were issued on the Closing Date, $30.0 million were issued on February 13, 2020, and $20.0 million were issued on December 1, 2020. An additional $20.0 million was available to us, but we did not meet the requirements to issue those additional Pharmakon Senior Secured Notes. On August 13, 2020, we entered into a letter agreement to the Note Purchase Agreement that provided us with the option to issue an additional $20.0 million of Pharmakon Senior Secured Notes, subject to achieving $26.0 million in consolidated XHANCE net sales and royalties in the quarter ended June 30, 2021 and certain other conditions. We are no longer eligible for the additional Pharmakon Senior Secured Notes as the requisite conditions were not satisfied as of June 30, 2021.

The Pharmakon Senior Secured Notes bear interest at a fixed per annum rate of 10.75% and are scheduled to mature on September 12, 2024 (the Maturity Date). We are required to make quarterly interest payments until the Maturity Date. We are also required to make principal payments, which are payable in eight equal quarterly installments beginning on December 15, 2022 and continuing until the Maturity Date; provided that we may elect to postpone any such principal payment until the Maturity Date if, as of the applicable payment date, certain minimum trailing four-quarter consolidated XHANCE net sales and royalties thresholds have been achieved. The Pharmakon Senior Secured Notes are guaranteed by OptiNose, Inc. and our subsidiaries and are secured by a pledge of substantially all of our and their assets.

Agreement. The Note Purchase Agreement as amended, contains various covenants that limit our ability to engage in specified types of transactions without our lenders’ prior consent, as well as financial
36

Table of Contents
covenants that require us to maintain at least $30.0 million of cash and cash equivalents in certain deposit accounts and require us to achieve certain minimum trailing twelve-month consolidated XHANCE net sales and royalties, tested on a quarterly basis. We are currently required to achieve consolidated XHANCE net sales and royalties of $80.0 million for the trailing twelve-month period ending December 31, 2021; $90.0 million, $98.75 million, $102.5 million, and $106.25 million for the trailing twelve-month periods ending March 31, June 30, September 30 and December 31, 2022, respectively; and increasingly higher quarterly requirements for calendar year 2023.

As of the filing of this quarterly report on Form 10-Q, we expect consolidated XHANCE net sales and royalties for the trailing twelve-month period ending December 31, 2021 to be between $71.0 million and $75.0 million. If we do not achieve $80.0 million of consolidated XHANCE net sales and royalties for the trailing twelve-month period ending December 31, 2021 and we are unable to obtain a waiver or modification to this financial covenant, we will be in breach of a financial covenant of the Note Purchase Agreement as of December 31, 2021, which will constitute an event of default under the terms of the Note Purchase Agreement. If the holders of the Pharmakon Senior Secured Notes elect to accelerate the repayment of all unpaid principal and accrued interest under such holders’ Pharmakon Senior Secured Notes, as described in the next paragraph, we may be forced to delay or reduce the scope of our development programs and clinical trials, our business, prospects, financial condition and results of operations will be materially and adversely affected, and we may be unable to continue as a going concern. These factors raise substantial doubt about our ability to continue as a going concern. If we are unable to continue as a going concern, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our audited financial statements, and it is likely that investors will lose all or a part of their investment.

Each holder of the Pharmakon Senior Secured Notes may elect to accelerate the repayment of all unpaid principal, and accrued interest and other amounts due under such holders’ Pharmakon Senior Secured Notes upon consummation of a specified change of control transaction or occurrence of certain events of default (as specified in the Note Purchase Agreement), including, among other things:

our default in a payment obligation under the Pharmakon Senior Secured Notes;

our breachdefault of or failure to comply with the financial, restrictive and other covenants or other terms of the Note Purchase Agreement or Pharmakon Senior Secured Notes;Notes issued thereunder;

our breach of reporting obligations;

our failure to properly maintain the collateral;

any circumstance that could reasonably be expected to have a material adverse effect (as defined in the Note Purchase Agreement) on us;

certain regulatory and/or commercial actions that causes an ongoing delay in commercialization of XHANCE; and

certain specified insolvency and bankruptcy-related events.

Subject to any applicable cure period set forth in the Note Purchase Agreement or Pharmakon Senior Secured Notes, all amounts outstanding with respect tothe holders of the Pharmakon Senior Secured Notes (principalmay elect for all outstanding principal, accrued interest and accrued interest), as well as any applicable prepayment premiums or interest “make-whole” payments, would becomeother amounts due and payable immediately upon an event of default at a default interest rate of 13.75%. Our assets or cash flow may not be sufficient to fully repay our obligations under the Pharmakon Senior Secured Notes if the obligations thereunder are accelerated(including applicable prepayment premiums, interest “make-whole” payments and fees) to become immediately due and payable upon any eventsan event of default and may elect a default interest rate of 13.75% to apply during such default.

The duration and magnitude of the negative impact from the COVID-19 pandemic on XHANCE net revenues has previously affected, and could affect in the future, our ability to meet the consolidated XHANCE net product sales and royalties threshold to remain in compliance with our financial covenants.

In addition, on November 9, 2022, we entered into a Fourth Amendment to the Note Purchase Agreement to obtain a waiver of the minimum consolidated XHANCE net sales and royalties required to be achieved under the Note Purchase Agreement for the trailing twelve-month period ending September 30, 2022 and December 31, 2022 in exchange for a $1.3 million fee due on the repayment of the Pharmakon Senior Secured Notes. We believe it is probable that we will not achieve the trailing twelve-month minimum consolidated XHANCE net sales and royalties thresholds that we are required to achieve under the Note Purchase Agreement for the periods ending March 31, 2023, June 30, 2023 and September 30, 2023, which will constitute a default under the Note Purchase Agreement if we are unable to obtain a modification or waiver of such minimum consolidated XHANCE net sales and royalties thresholds. We also believe that it is probable that our existing cash and cash equivalents will not be sufficient fund our operations and maintain at least $30.0 million of cash and cash equivalents as required under the Note Purchase Agreement for at least twelve-months following the filing of this Form 10-Q, which will constitute a default of the liquidity financial covenant under the Note Purchase Agreement if we are unable to obtain additional capital or obtain a waiver or modification to the liquidity covenant prior to falling below such $30.0 million threshold. In the event that any one of the foregoing defaults were to occur, the holders of the Pharmakon Senior Secured Notes may declare an event of default under Note Purchase Agreement and may elect to accelerate the repayment of all unpaid principal, accrued interest and other amounts due under such holders’ Pharmakon Senior Secured Notes.

If our assets or cash flows from operations are not sufficient to fully repay our obligations under the Pharmakon Senior Secured Notes, then we will be required to obtain additional capital through equity or debt financings, partnerships, collaborations, or other sources in order to meet such payment obligations, and to carry out our planned development and commercial activities. The holders of the Pharmakon Senior Secured Notes have, in the past, conditioned modifications to the minimum trailing twelve-month consolidated XHANCE net sales and royalties financial covenant and other provisions of the Note Purchase Agreement on our securing additional capital through equity financings and other conditions and fees, and could do so again in the future, which would impact the timing and amount of capital that we may seek to raise in a financing. There can be no guarantee that the holders of the Pharmakon Senior Secured Notes will provide a waiver or modification if requested. In addition, in order to complete future financings the investors in such financings may require us to obtain certain modifications to the minimum

Further, if we are unable to repay, refinance or restructure our obligations under the Pharmakon Senior Secured Notes, or obtain a waiver or modification to the financial covenants under the Note Purchase Agreement when needed, the holders of such Pharmakon Senior Secured Notes could proceed to protect and enforce their rights under the Pharmakon Senior Secured Notes by exercising such remedies (including foreclosure on the assets securing our obligations under the Pharmakon Senior Secured Notes and the Note Purchase Agreement) as are available to the holders thereunder and in respect thereof under applicable law, either by suit in equity or by action at law, or both, whether for specific performance of any covenant or other agreement contained in the Pharmakon Senior Secured Notes or Note Purchase Agreement or in aid of the exercise of any power granted in the Pharmakon Senior Secured Notes.Notes or Note Purchase Agreement. Any such action would materially and adversely affect the ongoing viability of our business.

Risks Related to COVID-19

The coronavirus (COVID-19) pandemic has and may continue to adversely affect our business, results of operations and financial condition.

In March 2020, the World Health Organization declared the outbreak of a novel coronavirus, or COVID-19, as a pandemic (the “COVID-19 pandemic”), which continues to spread throughout the U.S. and worldwide. On March 13, 2020, the then-President of the United States announced a national emergency relating to the COVID-19 pandemic.
Government authorities in the U.S. have recommended or imposed various social distancing, quarantine, and isolation measures on large portions of the population, and similar measures have also been taken in many other countries around the world. These measures have changed, and will continue to change, based on the severity and uncertainties of the COVID-19 pandemic.

In March 2020, we modified our business practices and transitioned to a full-time, virtual work environment in which all employees were encouraged to work from their place of residence if their job functions allowed, and all work-related travel was temporarily discontinued. A significant portion of the physicians' offices in which our territory managers detail XHANCE either were closed, had reduced patient flow or temporarily stopped sales representatives’ visits, which has hindered our ability to detail XHANCE to physicians' offices. Late in the first quarter of 2020, we began to observe an adverse impact of the COVID-19 pandemic on XHANCE prescription growth and net revenues, and we subsequently withdrew our previous XHANCE revenue guidance for 2020. This adverse impact on our revenues was most pronounced during the “shelter-in-place” mitigation efforts that were prevalent from late-March through May 2020. Where permitted by governmental requirements and the policies of physician offices, our territory managers began to return to in-person detailing of physicians in May and June 2020, however, many restrictions remain and some physicians' offices are still not accepting visits from sales representatives and others are limiting or placing restrictions on visits, which has negatively impacted our ability to drive prescription growth from the physicians targeted by our sales representatives. If our territory managers continue to have a limited ability to meet in person with physicians and if patients’ visits to doctors continue to be limited, XHANCE prescription growth and net revenues will continue to be adversely impacted. We expect these impacts of the COVID-19 pandemic to negatively impact XHANCE product revenues for the remainder of 2021 and into 2022. In addition, reduced patients visiting physician officers, changes in insurance coverage or reimbursement levels by governmental authorities, private health insurers and other third-party payors, or in the type of such coverage held by patients, due to the impacts of the COVID-19 pandemic, including the impact on U.S unemployment rates, may also negatively impact XHANCE prescription growth and net revenues.

The duration and magnitude of the negative impact from the COVID-19 pandemic on XHANCE net revenues could also affect our ability to remain in compliance with our financial covenants. As of the filing of this quarterly report on Form 10-Q, we expect consolidated XHANCE net sales and royalties for the trailing twelve-month period ending December 31, 2021 to be between $71.0 million and $75.0 million. If we do not achieve $80.0 million of consolidated XHANCE net sales and royalties for the trailing twelve-month period ending December 31, 2021 and we are unable to obtain a waiver or modification to this financial covenant, we will be in breach of a financial covenant of the Note Purchase Agreement as of December 31, 2021, which will constitute an event of default under the terms of the Note Purchase Agreement. If the holders of the Pharmakon Senior Secured Notes elect to accelerate the repayment of all unpaid principal and accrued interest under such holder’s Pharmakon Senior Secured Note, we may be forced to delay or reduce the scope of our development programs and clinical trials, our business, prospects, financial condition and results of operations will be materially and adversely affected, and we may be unable to continue as a going concern. Furthermore, capital markets in the U.S. and around the world have also been negatively impacted by COVID-19; if market conditions continue to be volatile, it may harm our business, including our ability to obtain future financing.

Our ability to enroll patients and retain principal investigators and site staff for our ongoing clinical trials have been, and could continue to be, impaired due to the COVID-19 outbreak in their geographic areas, the prioritization of medical resources toward the COVID-19 pandemic, or as a result of quarantines and other restrictions that interrupt healthcare services. For example, previous guidance related to the expected timing of results from our ongoing chronic sinusitis trials indicated that top-line results from both trials would be available in the second half of 2021. Pauses or delays in patient enrollment due to factors related to COVID-19 have had, and may continue to have, varying effects in different geographies and over time have led to a change in our projected timeline for initial data availability and may lead to additional changes in the future. We now expect top-line from the first of our two ongoing Phase 3b chronic sinusitis trials in the first quarter of 2022 and from the second clinical trial in the second quarter of 2022. For those subjects currently participating in these studies, procedures to facilitate ongoing treatment and capture of data during periods of in-person care restrictions have been put in place. Furthermore, patients, investigators, or site staff have been and may continue to be unwilling or unable to comply with clinical trial protocols due to COVID-19 illness, concerns about the pandemic, or quarantines or other restrictions that impede

their movement. Any interruption in the supply of the study drug might also delay our ability to complete our ongoing clinical trials within our expected timelines. Significant delays in the completion of our ongoing clinical trials are costly and could adversely affect our business and financial condition.

COVID-19 may also have an adverse impact on our contract manufacturers, suppliers, PPN partners, wholesalers, distributors and third party logistic provider as a result of employees or other key personnel becoming infected, preventive and precautionary measures that governments or such third parties are taking, such as social distancing, quarantines, and other restrictions, and shortages of supplies necessary for the manufacture of XHANCE. Any of these circumstances could adversely impact the ability of third parties on which we rely to manufacture and distribute adequate volumes of XHANCE. For example, in April 2020, our contract manufacturer for the formulation and assembly of finished XHANCE drug product implemented a reduced work schedule in response to the pandemic which resulted in temporary delays relating to the assembly of XHANCE finished goods.

The extent to which COVID-19 impacts our business, our customers, and the third parties on whom we rely, such as our contract manufacturers, suppliers, PPN partners, wholesalers, distributors, third party logistics, contract research organizations, investigators for our clinical trials and other vendors, will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration of the outbreak and any resurgence, new information that may emerge concerning the severity of the coronavirus, the actions to contain the coronavirus or treat its impact, and the speed with which and the extent to which normal economic and operating conditions resume, among others.


ITEM 5. OTHER INFORMATION
On November 9, 2022, the Company and Pharmakon entered into a Fourth Amendment to the Note Purchase Agreement. The Fourth Amendment provided a waiver of the minimum consolidated XHANCE net sales and royalties required to be achieved under the Note Purchase Agreement for the trailing twelve-month period ending September 30, 2022 and December 31, 2022 in exchange for a $1,300 fee due upon repayment of the Pharmakon Senior Secured Notes.
