The following discussion and analysis of our financial condition and results of operations should be read together with our unaudited condensed consolidated financial statements and related notes thereto appearing elsewhere in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2021, which was filed with the Securities and Exchange Commission on March 29, 2022. This Quarterly Report on Form 10-Q contains forward-looking statements that involve substantial risks and uncertainties. The words "anticipate," "believe," "continue" "could," "estimate," "expect," "intend," "may," "might," "plan," "potential," "predict," "project," "should," "target," "would," and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. There are a number of important risks and uncertainties that could cause our actual results to differ materially from those indicated by forward-looking statements. We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements we make. We have included important factors in the cautionary statements included in this Quarterly Report on Form 10-Q, particularly in the section entitled "Risk Factors" in Part II, Item 1A that we believe could cause actual results or events to differ materially from the forward-looking statements that we make. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures or investments that we may make.

Unless otherwise indicated, all information in this Quarterly Report on Form 10-Q gives effect to a 1-for-50 reverse stock split of our common stock that became effective on October 20, 2022, and all references to historical share and per share amounts give effect to the reverse stock split.

We are a clinical-stage biopharmaceutical company focused on the research, development and commercialization of innovative therapies for rare diseases of the eye. Our product candidate, KPI-012, which we acquired from Combangio, Inc., or Combangio, on November 15, 2021, is a mesenchymal stem cell secretome, or MSC-S, and is currently in clinical development for the treatment of persistent corneal epithelial defects, or PCED, a rare disease of impaired corneal healing. Based on the positive results of a Phase 1b clinical efficacy trial of KPI-012 in patients with PCED, we plan to submit an investigational new drug application, or IND, to the U.S. Food and Drug Administration, or FDA, for KPI-012 and, subject to regulatory clearance, commence a Phase 2/3 clinical trial for PCED in the United States in the fourth quarter of 2022.

We believe the multifactorial mechanism of action of KPI-012 also makes MSC-S a platform technology. We are evaluating KPI-012 in indications for rare front of the eye diseases, such as for the treatment of Partial Limbal Stem Cell Deficiency and ocular manifestations of moderate-to-severe Sjögren's. In addition, we are planning to initiate preclinical studies under our KPI-014 program to evaluate the utility of our MSC-S platform for retinal degenerative diseases, such as Retinitis Pigmentosa and Stargardt Disease, with the goal to select a retinal indication for development in the second half of 2023. In connection with the determination to focus our research and development efforts on KPI-012, we determined to cease the development of our preclinical pipeline programs that are unrelated to our MSC-S platform, including the development of KPI-287, our receptor tyrosine kinase inhibitor, and our selective glucocorticoid receptor modulators. We expect to commercialize in the United States any of our product candidates that receive marketing approval. For a further description of our acquisition of Combangio, KPI-012 and PCED, see our Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

We previously developed and commercialized two marketed products, EYSUVIS® (loteprednol etabonate ophthalmic suspension) 0.25%, for the short-term (up to two weeks) treatment of the signs and symptoms of dry eye disease, and INVELTYS® (loteprednol etabonate ophthalmic suspension) 1%, a topical twice-a-day ocular steroid for the treatment of post-operative inflammation and pain following ocular surgery. Both products applied a proprietary mucus-penetrating particle drug delivery technology, which we referred to as the AMPPLIFY® Drug Delivery Technology.

On July 8, 2022, we closed the transaction, or the Alcon Transaction, contemplated by the asset purchase agreement, dated as of May 21, 2022, or the Asset Purchase Agreement, by and between us, Alcon Pharmaceuticals Ltd. and Alcon Vision, LLC, or together referred to as Alcon, pursuant to which Alcon purchased the rights to manufacture,



                                       36

Table of Contents

sell, distribute, market and commercialize EYSUVIS and INVELTYS and to develop, manufacture, market and otherwise exploit the AMPPLIFY Technology, which we collectively refer to as the Commercial Business. Alcon also assumed certain liabilities with respect to the Commercial Business at the closing of the Alcon Transaction.

Alcon paid us an upfront cash payment of $60.0 million upon the closing of the Alcon Transaction. Pursuant to the Asset Purchase Agreement, we are also eligible to receive from Alcon up to four commercial-based sales milestone payments as follows: (1) $25.0 million upon the achievement of $50.0 million or more in aggregate worldwide net sales of EYSUVIS and INVELTYS in a calendar year from 2023 to 2028, (2) $65.0 million upon the achievement of $100.0 million or more in aggregate worldwide net sales of EYSUVIS and INVELTYS in a calendar year from 2023 to 2028, (3) $75.0 million upon the achievement of $175.0 million or more in aggregate worldwide net sales of EYSUVIS and INVELTYS in a calendar year from 2023 to 2029 and (4) $160.0 million upon the achievement of $250.0 million or more in aggregate worldwide net sales of EYSUVIS and INVELTYS in a calendar year from 2023 to 2029. Each milestone payment will only become payable once, if at all, upon the first time such milestone is achieved, and only one milestone payment will be paid with respect to a calendar year. In the event that more than one milestone is achieved in a calendar year, the higher milestone payment will become payable and the lower milestone payment will become payable only if the corresponding milestone is achieved again in a subsequent calendar year.

In connection with our entry into the Asset Purchase Agreement, on May 21, 2022, we entered into an amendment, or the Loan Amendment, with Oxford Finance LLC, or Oxford Finance, to the Loan and Security Agreement, or the Loan Agreement, by and among us, Combangio, Inc. and Oxford Finance, in its capacity as Lender, and in its capacity as Agent. Pursuant to the Loan Amendment, the Lender and Agent consented to the entry by us into the Asset Purchase Agreement and the sale of the Commercial Business to Alcon and agreed to release its liens on the Commercial Business in consideration for the payment by us at the closing of the Alcon Transaction of an aggregate amount of $40.0 million, or the Prepayment, to the Lender and Agent. The Prepayment, which represented a partial prepayment of principal in the amount of $36.7 million of the $80.0 million principal amount outstanding under the term loan advanced by the Lender under the Loan Agreement, plus a prepayment fee of $0.7 million and a final payment fee of $2.6 million, was paid on July 8, 2022 in connection with the closing of the Alcon Transaction. In addition, we were required to pay all accrued and unpaid interest on the principal amount of the term loan being repaid.

Under the Loan Amendment, following the closing of the Alcon Transaction and the Prepayment, the start date for amortization payments under the Loan Agreement was extended from December 1, 2024 to January 1, 2026, at which time the aggregate principal balance of the term loan then outstanding under the Loan Agreement is required to be repaid in five monthly installments. Pursuant to the Loan Amendment, we may also make partial prepayments of the term loan to the Lender, subject to specified conditions, including the payment of applicable fees and accrued and unpaid interest on the principal amount of the term loan being repaid.

On July 8, 2022, we announced that we had committed to a course of action to terminate 113 employees, consisting of our entire commercial sales force and certain employees in our commercial, scientific, manufacturing, finance and administrative functions. The determination to proceed with the workforce reduction was made in the context of the closing of the Alcon Transaction and the changes to the scope of our research and development activities of KPI-012 as more fully described above. We expect to complete the workforce reduction, to streamline our corporate infrastructure, by December 31, 2022. We expect the workforce reduction to result in approximately $27.6 million in reduced annualized operating expenses once the workforce reduction is fully implemented. In addition, we expect to incur total charges of approximately $2.3 million which were primarily recorded in the third quarter of 2022 related to the workforce reduction, consisting of severance, benefits and related costs, all of which are anticipated to be paid prior to the end of the first quarter of 2023.

Since inception, we have incurred significant losses from operations and negative cash flows from operations. Our net income was $29.1 million for the three months ended September 30, 2022 as a result of the Alcon Transaction and our net losses were $32.0 million and $142.6 million for the nine months ended September 30, 2022 and the year ended December 31, 2021, respectively. As of September 30, 2022, we had an accumulated deficit of $574.4 million. As we commenced a full promotional launch of EYSUVIS in early January 2021 and commercially launched our first product, INVELTYS, in January 2019, we had generated only limited revenues from product sales prior to the sale of the Commercial Business to Alcon in July 2022. We had financed our operations primarily through proceeds from the sale

of our Commercial Business to Alcon in July 2022, our initial public offering, or IPO, follow-on public common stock offerings and sales of our common stock under our sales agreement with Jefferies, LLC, or Jefferies, in at-the-market offerings, or ATM Offerings, private placements of preferred stock, borrowings under credit facilities and our Loan Agreement with Oxford Finance, convertible promissory notes and warrants. We have devoted substantially all of our financial resources and efforts to research and development, including preclinical studies and clinical trials and, prior to the sale of our Commercial Business to Alcon in July 2022, engaging in activities to launch and commercialize EYSUVIS and INVELTYS. As a result of our acquisition of Combangio and the sale of our Commercial Business to Alcon, we intend to devote substantial financial resources to the research and development and potential commercialization of KPI-012. We have no revenue-generating commercial products, and although we are eligible to receive up to $325.0 million in payments from Alcon based upon the achievement of specified commercial sales-based milestones with respect to EYSUVIS and INVELTYS, there can be no assurance when we may receive such milestone payments or the amount of milestone payments we may receive, if any. We expect to continue to incur significant expenses and operating losses for the foreseeable future, including in connection with our continued development, regulatory approval efforts and commercialization, if any, of KPI-012. We may never achieve or maintain profitability. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year.

Business Impact of COVID-19 Pandemic

In order to safeguard the health of our employees from the ongoing COVID-19 pandemic, we are following, and will continue to follow, recommendations from the U.S. Centers for Disease Control and Prevention, as well as federal, state, and local governments, regarding working-from-home practices for non-essential employees.

In addition, government restrictions have at times led to moratoria on elective ocular surgeries in many jurisdictions, which had significantly reduced the demand for INVELTYS, which is indicated for the treatment of inflammation and pain following ocular surgery. While surgeries have returned to historical levels, the COVID-19 pandemic had negatively impacted revenues from INVELTYS in prior periods. In addition, the COVID-19 pandemic has generally had an adverse impact on the launch of pharmaceutical products, and we believe the pandemic impacted the launch of EYSUVIS. We cannot predict whether the COVID-19 pandemic will impact Alcon's ability to commercialize EYSUVIS and INVELTYS, and as a result, it cannot be certain whether the COVID-19 pandemic might adversely affect when we may receive milestone payments from Alcon, which milestone payments we may receive and if we will receive any milestone payments at all. We also do not know the extent to which the COVID-19 pandemic will impact our development of KPI-012 or any other product candidate we develop. Any impact of the COVID-19 pandemic on Alcon's commercialization efforts of EYSUVIS and INVELTYS, our development of KPI-012 and any other product candidate we may develop in the future, and our operational and financial performance will depend on certain developments, including the length and severity of this pandemic, the timing and extent of any resurgence of the COVID-19 virus or any variant strains of the virus, the availability and effectiveness of vaccines, and the full extent of the impact on customers, employees, vendors and government agencies, all of which are uncertain and cannot be predicted.

Management is actively monitoring the COVID-19 pandemic and its effects on our financial condition, liquidity, operations, customers, sales force, contractors, and workforce. For additional information on risks posed by the COVID-19 pandemic, please see Part II, Item 1A - "Risk Factors" of this Quarterly Report on Form 10-Q, including the risk factor entitled "The ongoing novel coronavirus pandemic and the efforts to prevent its spread have adversely impacted our operations, could impact the development of KPI-012 or any other product candidate we develop, and may continue to adversely affect our business, results of operations and financial condition."

Recent Developments

Dividend Series D Preferred Stock

On August 18, 2022, our Board of Directors, or the Board, declared a dividend of one one-thousandth of a share of our Series D Preferred Stock, or the Series D Preferred Stock, for each outstanding share of our common stock held of record as of 5:00 p.m. Eastern Time on August 29, 2022, or the Record Date. This dividend was based on the number of



                                       38

Table of Contents

outstanding shares of common stock prior to the Reverse Stock Split, which is more fully described below. As of September 30, 2022, there were 73,208 shares of Series D Preferred Stock issued and outstanding.

Special Meeting of Stockholders

We held a special meeting of stockholders on October 19, 2022, or the Special Meeting, at which meeting our stockholders approved an amendment to our Restated Certificate of Incorporation, or the Certificate of Incorporation, to effect a reverse stock split of our common stock at a ratio in the range of 1-for-2 to 1-for-75, with such ratio to be determined by our Board and included in a public announcement (the "Reverse Stock Split Proposal"). The outstanding shares of Series D Preferred Stock were entitled to vote together with the outstanding shares of our common stock, as a single class, exclusively with respect to the Reverse Stock Split Proposal, as well as any proposal to adjourn any meeting of stockholders called for the purpose of voting on the Reverse Stock Split Proposal, or the Adjournment Proposal.

Redemption of Series D Preferred Stock

All shares of Series D Preferred Stock that were not present in person or by proxy at the Special Meeting were automatically redeemed by us immediately prior to the opening of the polls at Special Meeting, or the Initial Redemption. All shares that were not redeemed pursuant to the Initial Redemption were redeemed automatically upon the approval by our stockholders of the Reverse Stock Split Proposal at the Special Meeting, or the Subsequent Redemption, which together with the Initial Redemption, we refer to as the Redemption. Each share of Series D Preferred Stock was entitled to receive $0.10 in cash for each 100 whole shares of Series D Preferred Stock immediately prior to the Redemption. As of November 7, 2022, both the Initial Redemption and the Subsequent Redemption have occurred. As a result, no shares of Series D Preferred Stock remain outstanding.

We were not solely in control of Redemption of the shares since the holders had the option of deciding whether to return a proxy card for the Special Meeting, which determined whether a given holder's shares of Series D Preferred Stock were redeemed in the Initial Redemption or the Subsequent Redemption. Since the redemption of the Series D Preferred Stock was not solely in our control, the shares of Series D Preferred Stock are classified within mezzanine equity in our unaudited condensed consolidated balance sheets. The shares of Series D Preferred Stock were initially measured at redemption value. The value of the shares of Series D Preferred Stock as of September 30, 2022 was de minimis.

Reverse Stock Split

Following the Special Meeting, the Board determined to effect a reverse stock split at a ratio of 1-for-50 and approved the corresponding final form of the Certificate of Amendment. On October 19, 2022, we filed the Certificate of Amendment with the Secretary of State of Delaware to effect a 1-for-50 reverse stock split of the shares of our common stock either issued and outstanding or held by us as treasury stock, effective as of 4:05 p.m. (Delaware time) on October 20, 2022, or the Reverse Stock Split.

As a result of the Reverse Stock Split, every 50 shares of issued and outstanding common stock were automatically combined into one issued and outstanding share of common stock, without any change in the par value per share. No fractional shares were issued as a result of the Reverse Stock Split. Any fractional shares that would otherwise have resulted from the Reverse Stock Split were rounded up to the next whole number. The Reverse Stock Split reduced the number of shares of common stock outstanding from 73,208,140 shares to 1,476,637 shares. The number of authorized shares of common stock under the Certificate of Incorporation remained unchanged at 120,000,000 shares. All historical share and per share amounts reflected throughout this report have been adjusted to reflect the Reverse Stock Split described above.

Proportionate adjustments were made to the per share exercise price and the number of shares of common stock that may be purchased upon exercise of outstanding stock options and warrants, and the number of shares of common stock reserved for future issuance under our 2017 Equity Incentive Plan and Employee Stock Purchase Plan.

Financial Operations Overview

Product Revenues, Net

We commenced generating product revenues from sales of INVELTYS in January 2019, and commenced generating revenue from EYSUVIS upon the shipment to wholesalers in the United States in late December 2020. Full promotional launch of EYSUVIS began in early January 2021. On July 8, 2022, we sold our Commercial Business, including EYSUVIS and INVELTYS, to Alcon and ceased recording gross revenue on sales of EYSUVIS and INVELTYS. Our product revenues for the periods presented herein are recorded net of provisions relating to estimates for (i) trade discounts and allowances, such as discounts for prompt payment and other discounts and distributor fees, (ii) estimated rebates, chargebacks and co-pay assistance programs, and (iii) reserves for expected product returns. These estimates reflect current contractual and statutory requirements, known market events and trends, industry data and forecasted customer buying and payment patterns. Actual amounts may ultimately differ from these estimates. If actual results vary, estimates may be adjusted in the period such change in estimate becomes known, which could have an impact on earnings in the period of adjustment.

We currently have no commercial products in our portfolio. Moreover, subject to regulatory clearance, we plan to commence a Phase 2/3 clinical trial of KPI-012 for PCED in the United States in the fourth quarter of 2022 and, accordingly, we do not expect to generate revenue from KPI-012 or any other product candidate we may develop in the future for the foreseeable future, if at all. See the section titled "Business Impact of COVID-19 Pandemic" above for information about the impact of COVID-19 on sales and commercialization of EYSUVIS and INVELTYS.

Cost of Product Revenues

Cost of product revenues consists primarily of materials, third-party manufacturing costs, freight and distribution costs, royalty expense, allocation of labor, quality control and assurance, reserves for defective inventory, reserves for excess and obsolete inventory, losses on inventory purchase commitments, and other manufacturing overhead costs. The determination of whether inventory costs will be realizable requires estimates by management. If actual market conditions are less favorable than projected by management, additional write-downs of inventory may be required which would be recorded as a cost of product revenues in the condensed consolidated statements of operations and comprehensive loss. We expensed cost of product revenues related to INVELTYS as research and development expenses prior to U.S. regulatory approval, which we received on August 22, 2018. We expensed cost of product revenues related to EYSUVIS as research and development expenses prior to the determination that FDA approval was probable and before the future economic benefit was expected to be realized. As a result of the sale of our Commercial Business to Alcon, which occurred on July 8, 2022, we do not expect to generate cost of product revenues until such time as we commercialize another product candidate.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of salaries, benefits, commissions, stock-based compensation and travel expenses related to our commercial infrastructure and our executive, finance, human resources, legal, compliance, information technology and business development functions. Selling, general and administrative expenses also include external selling and marketing costs, costs to manufacture sample units and professional fees for auditing, tax, information technology, consultants, legal services and allocated facility-related costs not otherwise included in research and development expenses.

We expect that our selling, general and administrative expenses for 2022 will decrease as compared to such expenses for the year ended December 31, 2021 as a result of the workforce reduction announced on July 8, 2022, and because we completed the sale of our Commercial Business to Alcon, incurred launch-related expenses for EYSUVIS during 2021 that we will not incur again in 2022 and terminated the lease for our corporate headquarters, effective January 11, 2022. We anticipate that our selling, general and administrative expenses will decrease in 2023 as compared to the year ending December 31, 2022 and then will remain largely consistent with the expenses for 2023 for the foreseeable future as we continue to support our development efforts for KPI-012 and seek marketing approval for KPI-012 and any other product candidate we may develop in the future. If we obtain marketing approval for KPI-012 or any



                                       40

Table of Contents

product candidates we may develop, we expect that our selling, general and administrative expenses will increase substantially if and as we incur commercialization expenses related to product marketing, sales and distribution.

Research and Development Expenses

Research and development expenses consist of costs associated with our research activities, including compensation and benefits for full-time research and development employees, an allocation of facilities expenses, overhead expenses and certain outside expenses. Our research and development expenses include:

? employee-related expenses, including salaries, related benefits, travel and

stock-based compensation;

expenses incurred for the preclinical and clinical development of our product

candidates and under agreements with contract research organizations, including

? costs of manufacturing product candidates prior to the determination that FDA

approval of a drug candidate is probable and before the future economic benefit

of the drug is expected to be realized; and

? facilities, depreciation and other expenses, which include direct and allocated

expenses for rent and maintenance of facilities and supplies.

We expense research and development costs as they are incurred. We expense costs relating to the production of inventory for our product candidates, as research and development expenses within our condensed consolidated statements of operations and comprehensive loss in the period incurred, unless we believe regulatory approval and subsequent commercialization of the product candidate is probable and we expect the future economic benefit from sales of the drug to be realized. Research and development costs that are paid in advance of performance are capitalized as a prepaid expense until incurred. We track outsourced development costs by development program but do not allocate personnel costs, payments made under our license agreements or other costs to specific product candidates or development programs. These costs are included in employee-related costs and other research and development costs in the line items in the tables under "Results of Operations".

We expect that our research and development costs for 2022 will increase as compared to such expenses for the year ended December 31, 2021 as we advance the clinical development of KPI-012 and as we conduct any necessary preclinical studies and clinical trials and other development activities for any other product candidate we may develop in the future, including our planned preclinical studies under our KPI-014 program. The process of conducting preclinical studies and clinical trials necessary to obtain regulatory approval is costly and time-consuming. We may never succeed in obtaining marketing approval for any of our product candidates. The probability of success for each product candidate may be affected by numerous factors, including preclinical data, clinical data, competition, manufacturing capability and commercial viability. With respect to the ongoing COVID-19 pandemic, we are unable to predict the impact it may have on our research and development activities.

Subject to regulatory clearance, we plan to commence a Phase 2/3 clinical trial of KPI-012 for PCED in the United States in the fourth quarter of 2022. Successful development and completion of preclinical studies and clinical trials is uncertain and may not result in approved products. Completion dates and completion costs can vary significantly for each product candidate and future product candidate and are difficult to predict. We will continue to make determinations as to which product candidates to pursue and how much funding to direct to each product candidate on an ongoing basis in response to the scientific and clinical success of each product candidate as well as ongoing assessments as to the commercial potential of product candidates and our ability to enter into collaborations with respect to each product candidate. We will need to raise additional capital and may seek collaborations in the future to advance KPI-012 and any product candidate we may develop in the future. Additional private or public financings may not be available to us on acceptable terms, or at all. Our failure to raise capital as and when needed would have a material adverse effect on our financial condition and our ability to pursue our business strategy.

(Gain) Loss on Fair Value Remeasurement of Deferred Purchase Consideration

In connection with the closing of the acquisition of Combangio on November 15, 2021, or the Combangio Closing, we agreed to issue an aggregate of 155,799 shares, or the Deferred Purchase Consideration, of our common stock to former Combangio stockholders and other equityholders, or the Combangio Equityholders, consisting of (i) an aggregate of 136,314 shares of common stock which were issued on January 3, 2022 and (ii) an aggregate of 19,485 shares of common stock that have been held back by us and will be issuable subject to the terms of the merger agreement to the Combangio Equityholders on the date that is fifteen months after the Combangio Closing. We recorded an obligation for such Deferred Purchase Consideration at fair value on the acquisition date. We then revalue our Deferred Purchase Consideration obligations each reporting period. Changes in the fair value of our Deferred Purchase Consideration obligations, other than changes due to issuance, are recognized as a gain or loss on fair value remeasurement of Deferred Purchase Consideration in our condensed consolidated statements of operations and comprehensive loss.

(Gain) Loss on Fair Value Remeasurement of Contingent Consideration

In addition to the Deferred Purchase Consideration, consideration payable for the Combangio acquisition includes potential future payments that are contingent upon the achievement of specified development, regulatory and commercialization milestones. We recorded an obligation for such contingent consideration at fair value on the acquisition date. We then revalue our contingent consideration obligations each reporting period. Changes in the fair value of our contingent consideration obligations, other than changes due to issuance, are recognized as a gain or loss on fair value remeasurement of contingent consideration in our condensed consolidated statements of operations and comprehensive loss.

Interest Income

Interest income consists of interest earned on our cash, cash equivalents and short-term investments.

Interest Expense

Interest expense primarily consists of contractual coupon interest, amortization of debt discounts and debt issuance costs and accretion of the final payment fee recognized on our debt arrangements.

Gain on Sale of Commercial Business

Gain on sale of Commercial Business represents the gain recognized as a result of the sale of our Commercial Business to Alcon on July 8, 2022.

Loss on Extinguishment of Debt

Loss on extinguishment of debt primarily consists of unamortized debt discount and issuance costs, a prepayment premium and unaccreted final payment fees paid on our Loan Agreement with Oxford Finance as a result of the partial extinguishment of debt on July 8, 2022 in connection with the closing of the Alcon Transaction.

Critical Accounting Policies and Significant Judgments and Estimates

Our management's discussion and analysis of our financial condition and results of operations is based on our financial statements, which we have prepared in accordance with U.S. generally accepted accounting principles. We believe that several accounting policies are important to understanding our historical and future performance. We refer to these policies as critical because these specific areas generally require us to make judgments and estimates about matters that are uncertain at the time we make the estimate, and different estimates-which also would have been reasonable-could have been used. On an ongoing basis, we evaluate our estimates and judgments, including those described in greater detail below. We base our estimates on historical experience and other market-specific or other relevant assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making



                                       42

  Table of Contents

judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

There have been no material changes to our critical accounting estimates from those described in "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

Product revenues, net

Product revenues, net was $0.4 million for the three months ended September 30, 2022, which consisted of $0.4 million from EYSUVIS sales and less than $0.1 million from INVELTYS sales, compared to product revenues, net of $3.1 million for the three months ended September 30, 2021, which consisted of $1.8 million from EYSUVIS sales and $1.3 million from INVELTYS sales. The decrease in product revenues, net of $2.7 million was due to the sale of our Commercial Business to Alcon in July 2022, partially offset by the release of certain reserves. As a result of the sale of our Commercial Business, we no longer have any commercial products in our portfolio.

Cost of product revenues

Cost of product revenues was less than $0.1 million for the three months ended September 30, 2022, compared to $0.9 million for the three months ended September 30, 2021, which was a decrease of $0.9 million due to the sale of our Commercial Business to Alcon in July 2022.

due to the sale of our commercial product portfolio to Alcon and includes a $10.2 million decrease in employee-related expenses, a $4.3 million decrease in external sales and marketing costs, a $1.9 million decrease in stock-based compensation costs and certain medical affairs costs attributable to our former commercial products. Also contributing to the decrease as compared to the three months ended September 30, 2021, was a $1.4 million decrease in facility related costs. These decreases, as compared to the three months ended September 30, 2021, was partially offset by $1.5 million recorded to selling, general and administrative expenses related to the workforce reduction and $0.5 million increase in administrative and professional service fees.

Research and development expenses

During the three months ended September 30, 2022, $80.0 million of indebtedness was outstanding under our Loan Agreement until $36.7 million was repaid on July 8, 2022 resulting in an outstanding indebtedness of $43.3 million.

The decrease in product revenues, net of $5.5 million was largely due to the sale of our Commercial Business to Alcon in July 2022 as well as higher estimated allowances per unit sold on both products during the nine months ended September 30, 2022 as compared to those allowances per unit during the nine months ended September 30, 2021 and a decrease in the total units of INVELTYS sold in the first two quarters of 2022 as compared to the first two quarters of 2021, partially offset by a higher per unit gross selling price of both products during the nine months ended September 30, 2022 as compared to those sold during the nine months ended September 30, 2021. As a result of the sale of our Commercial Business, we no longer have any commercial products in our portfolio.

Cost of product revenues was $2.6 million for the nine months ended September 30, 2022, compared to $2.7 million in the nine months ended September 30, 2021, a decrease of $0.1 million. The decrease was due to a decrease in units of INVELTYS sold during the nine months ended September 30, 2022 as compared to the nine months ended September 30, 2021, partially offset by $0.8 million of reserves recorded for expiring inventory or inventory that did not pass quality inspection which did not occur in the nine months ended September 30, 2021.

Selling, general and administrative expenses

Selling, general and administrative expenses were $59.2 million for the nine months ended September 30, 2022, compared to $81.0 million for the nine months ended September 30, 2021, which was a decrease of $21.8 million.

contributing to the decrease as compared to the nine months ended September 30, 2021, was a $4.1 million decrease in facility related costs. These decreases, as compared to the nine months ended September 30, 2021, were partially offset by $1.5 million recorded to selling, general and administrative expenses related to the workforce reduction, a $1.4 million increase in administrative and professional service fees and $0.8 million of transaction costs related to the Alcon Transaction which were not incurred in the nine months ended September 30, 2021.

Liquidity and Capital Resources

Since our inception, we have incurred significant operating losses. As we commercially launched our first product, INVELTYS, in January 2019, and commenced a full promotional launch of our second product, EYSUVIS, in early January 2021, we only generated limited revenues to date from product sales prior to the sale of our Commercial Business to Alcon in July 2022. We have financed our operations primarily through proceeds from the sale of our Commercial Business to Alcon in July 2022, our IPO, follow-on public common stock offerings and sales of our common stock under our ATM Offerings, private placements of preferred stock, borrowings under credit facilities and the Loan Agreement, convertible promissory notes and warrants.

In July 2022, we sold our Commercial Business to Alcon. In addition to the upfront cash payment of $60.0 million we received from Alcon pursuant to the Asset Purchase Agreement, we are also eligible to receive from Alcon up to four commercial-based sales milestone payments as follows: (1) $25.0 million upon the achievement of $50.0 million or more in aggregate worldwide net sales of EYSUVIS and INVELTYS in a calendar year from 2023 to 2028, (2) $65.0 million upon the achievement of $100.0 million or more in aggregate worldwide net sales of EYSUVIS and INVELTYS in a calendar year from 2023 to 2028, (3) $75.0 million upon the achievement of $175.0 million or more in aggregate worldwide net sales of EYSUVIS and INVELTYS in a calendar year from 2023 to 2029 and (4) $160.0 million upon the achievement of $250.0 million or more in aggregate worldwide net sales of EYSUVIS and INVELTYS in a calendar year from 2023 to 2029. Each milestone payment will only become payable once, if at all, upon the first time such milestone is achieved, and only one milestone payment will be paid with respect to a calendar year. In the event that more than one milestone is achieved in a calendar year, the higher milestone payment will become payable and the lower milestone payment will become payable only if the corresponding milestone is achieved again in a subsequent calendar year. We now have no revenue-generating commercial products, and although we are eligible to receive up to $325.0 million in milestone-based payments from Alcon, there can be no assurance as to when we may receive such milestone payments or the amount of milestone payments we may receive, if any.

In July 2017, we completed an IPO pursuant to which we issued and sold 138,000 shares of our common stock, which included 18,000 shares sold pursuant to the exercise of the underwriters' option to purchase additional shares, at a price of $750.00 per share. We received net proceeds of $94.0 million after deducting underwriting discounts and commission of $7.3 million and offering costs of $2.2 million.

On August 9, 2018, we filed our shelf registration statement on Form S-3 that was declared effective by the SEC on August 27, 2018, or the 2018 Shelf Registration, under which we could initially offer and sell up to $250.0 million of a variety of securities including common stock, preferred stock, warrants, depositary shares, debt securities, purchase contracts, purchase units or any combination of such securities during the three-year period that commenced upon the 2018 Shelf Registration becoming effective. The 2018 Shelf Registration is now expired.

On October 1, 2018, we entered into the Athyrium Credit Facility with Athyrium for up to $110.0 million. The Athyrium Credit Facility provided for a Term Loan A in the aggregate principal amount of $75.0 million, and a Term Loan B in the aggregate principal amount of $35.0 million which we did not draw down. On May 4, 2021, concurrently with the closing of the Loan Agreement with Oxford Finance and the borrowing of the tranche A loan, we utilized substantially all of the proceeds from the tranche A term loan to repay in full all outstanding amounts owed under the Athyrium Credit Facility, under which we had an aggregate principal amount of $75.0 million of indebtedness outstanding. We terminated all commitments by Athyrium to extend further credit under the Athyrium Credit Facility and all guarantees and security interests granted by us thereunder. In connection with the termination of the Athyrium Credit Facility, we paid to the lenders a prepayment premium of $2.25 million and an exit fee of $0.8 million. The transaction resulted in a loss on extinguishment of debt of $5.4 million, consisting of the prepayment premium, the unamortized debt discount and the unaccreted exit fee.

On October 5, 2018, we sold 150,000 shares of common stock in an underwritten offering pursuant to the 2018 Shelf Registration at a public offering price of $412.50 per share, before underwriting discounts and commissions. In addition, the underwriters were granted an overallotment option to purchase an additional 22,500 shares of the common stock at the same public offering price, less underwriting discounts and commissions. On October 11, 2018, the underwriters exercised in full their option to purchase the overallotment shares. The total number of shares sold by us in

the offering was 172,500 shares, resulting in net proceeds to us, after underwriting discounts and offering expenses, of $66.1 million. In connection with the filing of the 2018 Shelf Registration, we entered into a sales agreement with Jefferies, pursuant to which we could issue and sell, from time to time, up to an aggregate of $50.0 million of our common stock in an ATM Offering, through Jefferies, as sales agent. Through the first quarter of 2020, we issued an aggregate of 98,913 shares of our common stock under the ATM Offering, resulting in net proceeds to us of $25.6 million. On March 10, 2020, we suspended and terminated the prospectus related to the ATM Offering.

On March 11, 2020, we sold 320,000 shares of our common stock in an underwritten offering pursuant to the 2018 Shelf Registration at a public offering price of $394.50 per share, resulting in net proceeds of $118.2 million, after underwriting discounts, commissions, and offering expenses. In addition, the underwriters of the offering were granted the option for a period of 30 days to purchase up to an additional 48,000 shares of common stock offered in the public offering at the public offering price, less underwriting discounts, commissions and offering expenses. On April 3, 2020, the underwriters exercised their option and purchased an additional 19,588 shares of common stock at $394.50 per share, resulting in net proceeds to us of $7.2 million, after underwriting discounts, commissions, and offering expenses. The total number of shares sold by us in the offering was 339,588, resulting in total net proceeds to us, after underwriting discounts, commissions and offering expenses, of $125.4 million.

Under the 2018 Shelf Registration, which has now expired, we issued an aggregate of 611,000 shares of common stock, including under the ATM Offering, resulting in aggregate gross proceeds to us of $231.7 million.

On May 7, 2020, we filed our shelf registration statement on Form S-3 that was declared effective by the SEC on May 7, 2020, or the 2020 Shelf Registration, under which we may offer and sell up to $350.0 million of a variety of securities including common stock, preferred stock, warrants, depositary shares, debt securities or units during the three-year period that commenced upon the 2020 Shelf Registration becoming effective. In connection with the filing of the 2020 Shelf Registration, we entered into an amended and restated sales agreement with Jefferies, pursuant to which we may issue and sell, from time to time, up to an aggregate of $75.0 million of our common stock under our ATM Offering. Through December 31, 2021, we issued and sold an aggregate of 171,626 shares of our common stock under the ATM Offering, resulting in net proceeds of $61.8 million, which included 2,283 and 113,950 shares of common stock issued and sold during the three and nine months ended September 30, 2021, respectively, resulting in net proceeds of $6.0 million and $40.7 million, respectively. As of September 30, 2022, there was $11.3 million of shares of common stock remaining under the ATM Offering that we may issue and sell in the future and, excluding the shares of common stock that may be offered under our ATM Offering, there was $275.0 million of securities available to be issued under the 2020 Shelf Registration.

On May 4, 2021, we entered into the Loan Agreement with Oxford Finance, in its capacity as lender, or the Lender, and in its capacity as collateral agent, or Agent, pursuant to which a term loan of up to an aggregate principal amount of $125.0 million is available to us, consisting of (i) a tranche A term loan that was disbursed on the closing date of the Loan Agreement in the aggregate principal amount of $80.0 million; (ii) a contingent tranche B term loan in the aggregate principal amount of $20.0 million available to us through June 30, 2023 and within 90 days of our achieving trailing 6-month product revenue equal to or greater than $75.0 million, subject to certain other terms and conditions; and (iii) a contingent tranche C term loan in the aggregate principal amount of $25.0 million available to us through December 31, 2023 and within 90 days of our achieving trailing 6-month product revenue equal to or greater than $100 million, subject to certain other terms and conditions. The term loans bear interest at a floating rate equal to the greater of 30-day LIBOR and 0.11%, plus 7.89%. Certain of the customary negative covenants limit our and certain of our subsidiaries' ability, among other things, to incur future debt, grant liens, make investments, make acquisitions, distribute dividends, make certain restricted payments and sell assets, subject in each case to certain exceptions. A delisting of our common stock from the Nasdaq Global Select Market after a specified cure period is also an event of default under our Loan Agreement. Under the Loan Amendment entered into in connection with our entry into the Asset Purchase Agreement with Alcon, the Lender and Agent consented to the entry by us into the Asset Purchase Agreement and the sale of the Commercial Business to Alcon and agreed to release its liens on the Commercial Business in consideration for the Prepayment by us at the closing of the Alcon Transaction of an aggregate amount of $40.0 million to the Lender and Agent. The Prepayment, which represented a partial prepayment of principal in the amount of $36.7 million of the $80.0 million principal amount outstanding under the term loan advanced by the Lender under the Loan Agreement, plus a prepayment fee of $0.7 million and a final payment fee of $2.6 million, was paid on July 8, 2022 in

connection with the closing of the Alcon Transaction. The Loan Agreement, as amended by the Loan Amendment, extended the start date for amortization payments under the Loan Agreement from December 1, 2024 to January 1, 2026, at which time the aggregate principal balance of the term loan then outstanding under the Loan Agreement is required to be repaid in five monthly installments. All unpaid principal and accrued and unpaid interest with respect to each term loan is due and payable in full on May 1, 2026, or the Maturity Date.

We paid a facility fee of $0.4 million on the closing date of the Loan Agreement and have agreed to pay a facility fee of $0.1 million upon closing of the tranche B term loan and a $0.1 million facility fee upon the closing of the tranche C term loan. We will be required to make a final payment fee of 7.00% of the original principal amount of any funded term loan payable on the earlier of (i) the prepayment of the term loan in full or (ii) the Maturity Date. At our option, we may elect to make partial repayments of the term loan to the Lender, subject to specified conditions, including the payment of applicable fees and accrued and unpaid interest on the principal amount of the term loan being repaid. For further information about the Loan Agreement, see Note 11, "Debt", of our condensed consolidated financial statements.

As a result of the acquisition of Combangio, we may be required to pay additional contingent consideration to the former Combangio Equityholders. Pursuant to the Merger Agreement, former Combangio Equityholders are entitled to receive from us, subject to the terms and conditions of the Merger Agreement, cash or stock consideration which would become payable upon our achievement of various development, regulatory and sales milestones and as a result of certain cash royalty payment obligations. The total potential maximum payout for the milestone payments which are contingent upon the achievement of specified development, regulatory and commercialization milestones is $40.0 million and the total potential maximum payout for future sales-based milestone payments is an additional $65.0 million. At our option, we may satisfy a portion of certain of the milestone payments through either the payment of cash or the issuance of additional shares of our common stock up to 19.9% of the total number of shares of our common stock issued and outstanding immediately prior to the closing of the acquisition of Combangio. For a full description of the consideration payable as a result of the acquisition of Combangio, see our Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

Our other material cash requirements from known contractual and other obligations as of September 30, 2022 primarily related to licensing and commercial supply agreements. For information related to our future commitments relating to our licensing and commercial supply agreements, see Note 17, "Commitments and Contingencies", of our condensed consolidated financial statements.

Cash Flows

As of September 30, 2022 and 2021, we had $52.4 million and $124.5 million in cash and cash equivalents, respectively. As of September 30, 2022 and 2021, we had $43.3 and $80.0 million in indebtedness, respectively, which represented the aggregate principal amount that was outstanding under the Loan Agreement with Oxford Finance.



The following table summarizes our sources and uses of cash for each of the

Operating Activities

Net cash used in operating activities for the nine months ended September 30, 2022 was $65.2 million, compared to $80.3 million for the nine months ended September 30, 2021, a decrease of $15.1 million, primarily due to the timing of working capital fluctuations which accounted for $11.4 million of the decrease and the decrease in the net

  Table of Contents

loss adjusted for non-cash charges of $3.7 million. Notable working capital fluctuations include a decrease to accounts receivable in the nine months ended September 30, 2022 of $15.1 million as a result of the sale of our Commercial Business on July 8, 2022, whereas accounts receivable had increased by $3.0 million in the nine months ended September 30, 2021 driven by an increase in sales largely due to the launch of EYSUVIS. Prepaid expenses and other current assets increased $16.9 million during the nine months ended September 30, 2022, as compared to an increase of $1.2 million during the nine months ended September 30, 2021 as a result of receivables due from Alcon and third-parties in connection with transition related services.

Investing Activities

Net cash provided by investing activities for the nine months ended September 30, 2022 was $62.7 million compared to $75.4 million for the nine months ended September 30, 2021, a decrease of $12.7 million. Net cash provided by investing activities for the nine months ended September 30, 2022 related to proceeds from the disposition of the Commercial Business, net of transaction costs, of $62.9 million, proceeds from the sales or maturities of short-term investments of $5.0 million and proceeds from the sale of property and equipment of less than $0.1 million, partially offset by the purchases of short-term investments of $5.0 million and purchases of property and equipment and other assets of $0.3 million. Net cash provided by investing activities for the nine months ended September 30, 2021 consisted of the proceeds from the sales or maturities of short-term investments of $76.3 million, partially offset by purchases of property and equipment and other assets of $0.9 million.

Financing Activities

Net cash used in financing activities for the nine months ended September 30, 2022 was $39.7 million, a decrease of $82.1 million compared to net cash provided by financing activities of $42.4 million in the nine months ended September 30, 2021. Net cash used in financing activities for the nine months ended September 30, 2022 largely consisted of $40.0 million of repayment of principal, prepayment premium and final payment fee on our Loan Agreement, partially offset by $0.3 million of proceeds from the exercise of stock options and the issuance of common stock under our employee stock purchase plan. Net cash provided by financing activities for the nine months ended September 30, 2021 consisted of $77.8 million of net proceeds from the tranche A term loan under our Loan Agreement, $41.1 million of net proceeds from the sale of shares of our common stock under the ATM Offering and $1.5 million of proceeds from the exercise of stock options and the issuance of common stock under our employee stock purchase plan, partially offset by the repayment of indebtedness under our Athyrium Credit Facility of $78.0 million.

Funding Requirements

We anticipate that our research and development expenses will increase substantially in the future as compared to prior periods as we advance the clinical development of KPI-012. Our research and development expenses will also increase as we conduct any necessary preclinical studies and clinical trials and other development activities for any other product candidates we may develop in the future, including our planned preclinical studies under our KPI-014 program. If we obtain marketing approval for KPI-012 or any product candidates we may develop, we expect that our selling, general and administrative expenses will increase substantially if and as we incur commercialization expenses related to product marketing, sales and distribution.

Our expenses will also increase if and as we:

? submit an IND for, and continue the clinical development of, KPI-012 for PCED;

? initiate and continue the research and development of KPI-012 for additional

indications, including initiating and conducting clinical trials;

? scale up our manufacturing processes and capabilities to manufacture the

clinical supply of KPI-012;

? seek regulatory approval for KPI-012 for PCED in the United States and other


   jurisdictions;


                                       52

  Table of Contents

? seek regulatory approval for KPI-012 for additional indications;

grow our sales, marketing and distribution capabilities in connection with the

? commercialization of any product candidates for which we may submit for and

obtain marketing approval;

? initiate and progress any future preclinical development programs under our

MSC-S platform, including from our KPI-014 program;

? conduct clinical trials and other development activities and/or seek marketing

approval for any product candidates we may develop in the future;

? in-license or acquire the rights to other products, product candidates or

technologies;

? maintain, expand and protect our intellectual property portfolio;

? hire additional clinical, quality control, scientific, manufacturing,

commercial and management personnel to support our operations;

? expand our operational, financial and management systems; and

? increase our product liability insurance coverage if we initiate

commercialization efforts for any product candidates.

We expect to continue to incur significant expenses and operating losses. Net losses may fluctuate significantly from quarter-to-quarter and year-to-year. We anticipate that our cash and cash equivalents as of September 30, 2022, will enable us to fund our operations, debt service obligations, and capital expenditure requirements into the second quarter of 2024. We expect that our existing cash resources will be sufficient to enable us to obtain initial data from our planned Phase 2/3 clinical trial of KPI-012 in PCED. However, we do not expect that our existing cash resources will be sufficient to enable us to complete the clinical development of KPI-012 for PCED or any other indication. We have based our estimates on assumptions that may prove to be wrong, and our operating plan may change as a result of many factors currently unknown to us. As a result, we could deplete our available capital resources sooner or later than we currently expect. This estimate also assumes that we remain in compliance with the covenants under the Loan Agreement. In particular, the delisting of our common stock from the Nasdaq Global Select Market or the transfer of the listing of our common stock to the Nasdaq Capital Market or any other nationally recognized stock exchange having listing standards that are less restrictive than the Nasdaq Global Select Market, in each case after a specified cure period, are events of default under our Loan Agreement. We have received a deficiency letter from Nasdaq advising us that we are not in compliance with the Nasdaq Listing Rules for trading on the Nasdaq Global Select Market, and that if we are unable to regain compliance with such listing rules by January 2, 2023, our common stock will be subject to delisting. If an event of default or a breach of the covenants under our Loan Agreement occurs, including as a result of the delisting of our common stock from the Nasdaq Global Select Market, and we fail to secure a waiver or forbearance from the third-party lender, such breach or failure would accelerate the repayment of the outstanding indebtedness under the Loan Agreement. In such event, we may not be able to make accelerated payments, and the lender could seek to enforce security interests in the collateral securing such indebtedness. Acceleration of the repayment of the outstanding indebtedness would raise substantial doubt about the Company's ability to continue as a going concern, shorten the period for which we will be able to fund our operations and capital expenditure requirements and would adversely affect our financial condition and ability to pursue our business strategy. For additional information regarding the deficiency letters we have received from the Nasdaq Stock Market LLC, our obligations under the Loan Agreement and the potential impact on our financial condition from the delisting of our common stock from the Nasdaq Global Select Market, see "Risk Factors - If we fail to comply with the continued listing requirements of Nasdaq, our common stock may be delisted and the price of our common stock and our ability to access the capital markets could be negatively impacted. If our common stock is delisted from Nasdaq, we will be in default under our Loan Agreement." and "Risk Factors - Our substantial indebtedness may limit cash flow available to invest in the ongoing needs of our business and a failure to comply with the covenants under our Loan Agreement, such as the requirement that our common stock

continue to be listed on the Nasdaq Global Select Market, could result in an event of default and acceleration of amounts due."

Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve profitability. Our expenses will increase from what we anticipate if:

? we elect or are required by the FDA or non-U.S. regulatory agencies to perform

clinical trials or studies in addition to those expected;

? there are any delays in enrollment of patients in or completing our clinical

trials or the development of our product candidates;

? we in-license or acquire rights to other products, product candidates or

technologies; or

there are any third-party challenges to our intellectual property portfolio, or

? the need arises to defend against intellectual property-related claims or

enforce our intellectual property rights.

Although we are eligible to receive up to $325.0 million in payments from Alcon based upon the achievement of specified commercial sales-based milestones with respect to EYSUVIS and INVELTYS, there can be no assurance when we may receive such milestone payments or the amount of milestone payments we may receive, if any. Our ability to become and remain profitable depends on our ability to generate revenue. We do not expect to generate revenue from KPI-012 or any other product candidate we may develop in the future for the foreseeable future, if at all. Achieving and maintaining profitability will require us to be successful in a range of challenging activities, including:

? timely filing of an IND for, and completing the clinical development of,

KPI-012 for PCED and any other indications we determine to pursue;

? subject to obtaining favorable results from our planned clinical trials of

KPI-012, applying for and obtaining marketing approval of KPI-012;

? successfully commercializing KPI-012, if approved;

discovering, developing and successfully seeking marketing approval and

? commercialization of any additional product candidates we may develop in the

future;

? hiring and building a full commercial organization required for marketing,

selling and distributing those products for which we obtain marketing approval;

? manufacturing at commercial scale, marketing, selling and distributing those

products for which we obtain marketing approval;

achieving an adequate level of market acceptance, and obtaining and maintaining

? coverage and adequate reimbursement from third-party payors for any products we

commercialize;

? obtaining, maintaining and protecting our intellectual property rights; and

? adapting our business in response to the pandemic health event resulting from

COVID-19 and its collateral consequences.

As a company, we have limited experience commercializing products, and we may not be able to commercialize a product successfully in the future. There are numerous examples of unsuccessful product launches and failures to meet expectations of market potential, including by pharmaceutical companies with more experience and resources than us.

We may never succeed in our development activities or commercialization efforts, if any, of any product candidates that receive regulatory approval, and we may never generate revenue that is sufficient to achieve profitability. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would decrease the value of our company and could impair our ability to raise capital, expand our business, maintain our research and development efforts, diversify our product offerings or even continue our operations. A decline in the value of our company could also cause you to lose all or part of your investment.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements, royalty agreements, and marketing and distribution arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing and preferred equity financing, if available, may involve agreements that include pledging of assets as collateral, covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. Our pledge of our assets as collateral to secure our obligations under our Loan Agreement may limit our ability to obtain additional debt financing. Under our Loan Agreement, we are also restricted from incurring future debt, granting liens, making investments, making acquisitions, distributing dividends on our common stock, making certain restricted payments and selling assets and making certain other uses of our cash, without the lenders' consent, subject in each case to certain exceptions.

We will need to raise additional capital in the future to advance our business. Additional private or public financings may not be available to us on acceptable terms, or at all. Additionally, the COVID-19 pandemic has already caused significant disruptions in the financial markets, and may again cause such disruptions, which could impact our ability to raise additional funds. The COVID-19 pandemic has also impacted, and may continue to impact, the volatility of our stock price and trading in our stock. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business as a result of any economic recession or depression that has occurred or may occur in the future.

Our failure to raise capital as and when needed would have a material adverse effect on our financial condition and our ability to pursue our business strategy. If we raise additional funds through collaborations, strategic alliances, licensing arrangements, royalty agreements, or marketing and distribution arrangements, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or current or future commercialization efforts or grant rights to develop and market products or product candidates that we would otherwise prefer to develop and market ourselves.
