Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis of our financial condition and results of operations should be read together with our consolidated financial statements and related notes appearing elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties and should be read together with the “Risk Factors” section of this Annual Report on Form 10-K for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.
Overview
Our Company
We are a biopharmaceutical company committed to enhancing people’s vision and quality of life through the development and commercialization of innovative therapies for diseases and conditions of the eye, with a specific focus on retinal disease. Our program for retinal disease is led by AXPAXLI (axitinib intravitreal implant, also known as OTX-TKI), which is based on our ELUTYX proprietary bioresorbable hydrogel-based formulation technology. We are currently conducting a pivotal Phase 3 clinical trial to evaluate AXPAXLI for the treatment of wet age-related macular degeneration, or wet AMD, which we refer to as the SOL-1 trial, and a Phase 1 clinical trial for the treatment of diabetic retinopathy. Our clinical portfolio also includes PAXTRAVA (travoprost intracameral implant, also known as OTX-TIC), which is currently in Phase 2 clinical development for the treatment of primary open-angle glaucoma, or OAG, or ocular hypertension, or OHT.
Our expertise in the formulation, development and commercialization of innovative therapies and our ELUTYX platform supported the development and launch of our first commercial drug product, DEXTENZA, a corticosteroid approved by the U.S. Food and Drug Administration, or FDA, for the treatment of ocular inflammation and pain following ophthalmic surgery and ocular itching associated with allergic conjunctivitis. We are also developing two other clinical-stage assets, OTX-DED (dexamethasone intracanalicular insert) for the short-term treatment of the signs and symptoms of dry eye disease, and OTX-CSI (cyclosporine intracanalicular insert) for the chronic treatment of dry eye disease, which we collectively refer to as our Dry Eye Programs, and several preclinical programs.
Key Business and Financial Developments
Board of Directors and Leadership Updates
In February 2024, we expanded our leadership team and added Pravin Dugal, M.D. as Executive Chairman on a full-time basis. We also added Jeffrey Heier, M.D. as Chief Scientific Officer, Peter Kaiser, M.D. as Medical Director, both on a part-time basis, and Sanjay Nayak, MBBS, PhD as Chief Strategy Officer on a full-time basis. We believe the contribution of these acknowledged strategic and clinical experts will put the Company on track to be a leader in retina care for wet AMD, non-proliferative diabetic retinopathy, or NPDR, and other conditions.
In connection with these additions, Charles Warden transitioned from Chairman of the Board to Lead Independent Director. To enable full transitions to their new operating roles, Dr. Heier resigned from his positions with us as a Board Director and Advisor – Retina, and Dr. Kaiser resigned from his position as Chief Medical Advisor – Retina. In addition, Peter Jarrett, PhD has begun the new role of Chief Technical Officer. Rabia Gurses Ozden, M.D. will continue in her role as Chief Medical Officer.
AXPAXLI
We are conducting a pivotal Phase 3 clinical trial as the first of two planned pivotal trials for the treatment of wet AMD, which we refer to as the SOL-1 trial. The first subjects in the SOL-1 trial were screened and received their first aflibercept injection in February 2024. We expect to complete enrollment of the SOL-1 trial by the end of the first quarter of 2025. Subject to agreement with the FDA, we intend to commence screening of a second pivotal Phase 3 clinical trial for the treatment of wet AMD, which we refer to as the SOL-2 trial, by the first quarter of 2025.

Table of Contents
In September 2023, we submitted a request for a Special Protocol Assessment, or SPA, to the FDA to determine whether the proposed clinical protocol and the statistical analysis plan for the SOL-1 trial adequately addressed scientific and regulatory requirements for a clinical trial that could support a marketing application. We received an agreement letter regarding the overall trial design from the FDA under the SPA in October 2023. In December 2023, we submitted an amendment to the SPA to the FDA to broaden the inclusion criteria for subjects in the SOL-1 trial and to reflect our intention to evaluate a single optimized implant of AXPAXLI with a drug load of 450 µg of a more soluble form of axitinib in the SOL-1 trial, or the SPA Agreement Modification. We received an agreement letter regarding the SPA Agreement Modification in January 2024. If we were to obtain favorable results from both the SOL-1 trial and the SOL-2 trial, we plan to submit a New Drug Application, or NDA, with the FDA for marketing approval.
In June 2023, we presented 12-month data from the clinical trial of AXPAXLI for the treatment of wet AMD in the United States at the Clinical Trials at the Summit 2023 conference sponsored by the American Society of Retina Specialists.
We initiated a U.S.-based multicenter, double-masked, randomized, parallel group study evaluating the safety, tolerability and biological activity of AXPAXLI in patients with moderately severe to severe NPDR without DME, which we refer to as the HELIOS trial, in the fourth quarter of 2022. We dosed our first subject in February 2023. We announced the completion of enrollment in the HELIOS trial in June 2023 and expect to provide 9-month topline data in the second quarter of 2024. Subject to favorable topline data from the HELIOS trial and agreement with the FDA, we intend to commence a pivotal Phase 3 clinical trial.
PAXTRAVA
We are conducting a Phase 2 clinical trial evaluating the safety, tolerability and efficacy of PAXTRAVA for the treatment of subjects with primary OAG or OHT. We completed enrollment of this Phase 2 clinical trial in July 2023. We have started a pilot repeat-dose substudy in the Phase 2 clinical trial to evaluate the safety of a repeat, sustained release dose in a small subset of subjects with OAG or OHT. We plan to provide topline data from this Phase 2 clinical trial at the American Society of Cataract and Refractive Surgery 2024 Annual Meeting in April 2024. Subject to favorable topline data, we intend to evaluate our strategic alternatives in moving the PAXTRAVA program into pivotal Phase 3 clinical trials.
Commercial
Our net product revenue was $57.9 million for the year ended December 31, 2023, reflecting an increase of $7.4 million or 14.7% over the year ended December 31, 2022.
In November 2023, the Centers for Medicare and Medicaid Services, or CMS, released the final rulemaking for CY 2024 under the Outpatient Prospective Payment System, or OPPS. The final rule confirms that DEXTENZA will continue to be separately reimbursed by Medicare in the ambulatory surgical center, or ASC, setting under the non-opioid pain provision; and that CPT 68841, the code that describes the insertion of DEXTENZA, maintains a Q1 status indicator.
We believe that DEXTENZA is currently used in less than 5% of cataract procedures and that commercial growth may be driven by a continued focus on sales to ASCs, specifically strategic accounts that own and control multiple ASCs.
2024 Private Placement
In February 2024, concurrent with the Board of Directors and Leadership Updates detailed above, we sold 32,413,560 shares of our common stock at $7.52 per share and, in lieu of common stock to certain investors, pre-funded warrants to purchase up to an aggregate of 10,805,957 shares of our common stock at a price of $7.519 per pre-funded warrant for aggregate gross proceeds of approximately $325.0 million, before deducting placement agent fees and other offering expenses, or the 2024 Private Placement. Each pre-funded warrant has an exercise price of $0.001 per share, is currently exercisable and will remain exercisable until exercised in full.

2023 Equity Financing
In December 2023, we completed an underwritten public offering of 35,420,000 shares of our common stock at a public offering price of $3.25 per share. The total gross proceeds of the public offering were approximately $115.1 million, before deducting underwriting discounts and commissions and other offering expenses payable by us, resulting in net proceeds of approximately $107.7 million.
In 2023, we sold 1,514,926 shares of our common stock under our Open Market Sale Agreement with Jefferies LLC, or Jefferies, resulting in gross proceeds to us of $9.9 million, and net proceeds, after accounting for issuance costs, of $9.5 million.
2023 Debt Financing
In August 2023, we entered into a credit and security agreement, or the Barings Credit Agreement, with Barings Finance LLC, or Barings, as administrative agent, and the lenders party thereto, providing for a secured term loan facility for us, or the Barings Credit Facility, in the aggregate principal amount of $82.5 million. We borrowed the full amount of $82.5 million at closing and received proceeds of $77.3 million, after the application of an original issue discount and fees.
In March 2019, we issued $37.5 million of unsecured senior subordinated convertible notes, or the Convertible Notes. Concurrently with entering into the Barings Credit Agreement, in August 2023, we and the holders of the Convertible Notes extended the maturity of the Convertible Notes, which would otherwise have matured on March 1, 2026, to a date 91 days following the maturity of the indebtedness under the Barings Credit Facility.
In connection with entering the Barings Credit Facility, in August 2023, we paid MidCap Financial Trust, as administrative agent, and our other lenders an aggregate of $26.2 million in satisfaction of our obligations under our prior credit facility, which we refer to as the MidCap Credit Facility.
Collaborations
In the second quarter of 2023, we received a $1 million milestone payment from our collaboration partner AffaMed Therapeutics Limited, or AffaMed, upon the approval of AffaMed’s clinical trial application to initiate a Phase 3 registrational study in China to investigate the efficacy and safety of DEXTENZA in subjects following ophthalmic surgery by China’s National Medical Products Administration. In the second quarter of 2022, we received a $2 million clinical support payment in connection with dosing the first subject in a Phase 2 clinical trial evaluating PAXTRAVA for the treatment of OAG or OHT.
Components of our Financial Performance
Revenue
We recognize product revenue when we sell DEXTENZA in the United States to a network of specialty distributors on a direct basis, who then resell the product to ASCs and hospital out-patient departments, or HOPDs, and physicians’ offices, and when we sell DEXTENZA on a direct basis to a small number of ASCs. We refer to these resales from the specialty distributors to the ASCs and HOPDs as in-market unit sales. We record DEXTENZA product sales net of estimated chargebacks, rebates, distribution fees and product returns. These deductions are generally referred to as gross-to-net deductions.
Operating Expenses
Cost of Product Revenue
Cost of product revenue consists primarily of costs of DEXTENZA product revenue, which include:
● Direct materials costs;
● Royalties;
108
Table of Contents
● Direct labor, which includes employee-related expenses, including salaries, related benefits and payroll taxes, and stock-based compensation expense for employees engaged in the production process;
● Manufacturing overhead costs, which includes rent, depreciation, and indirect labor costs associated with the production process;
● Transportation costs; and
● Cost of scrap material.
Research and Development Expenses
Research and development expenses consist primarily of costs incurred for the development of our product candidates, which include:
● employee-related expenses, including salaries, related benefits and payroll taxes, travel and stock-based compensation expense for employees engaged in research and development, clinical and regulatory and other related functions;
● expenses incurred in connection with the clinical trials of our product candidates, including with the investigative sites that conduct our clinical trials and under agreements with contract research organizations, or CROs;
● expenses relating to regulatory activities, including filing fees paid to the FDA for our submissions for product approvals;
● expenses associated with developing our pre-commercial manufacturing capabilities and manufacturing clinical study materials;
● ongoing research and development activities relating to our core bioresorbable hydrogel technology and improvements to this technology;
● facilities, depreciation and other expenses, which include direct and allocated expenses for rent and maintenance of facilities, insurance and supplies;
● costs relating to the supply and manufacturing of product inventory, prior to approval by the FDA or other regulatory agencies of our products; and
● expenses associated with preclinical development activities.
We expense research and development costs as incurred. We recognize external development costs based on an evaluation of the progress to completion of specific tasks using information provided to us by our vendors and our clinical investigative sites.
Our direct research and development expenses are tracked on a program-by-program basis and consist primarily of external costs, such as fees paid to investigators, consultants, central laboratories and CROs in connection with our clinical trials and regulatory fees. We do not allocate employee and contractor-related costs, costs associated with our proprietary bioresorbable hydrogel-based formulation technology ELUTYX, costs related to manufacturing or purchasing clinical trial materials, and facility expenses, including depreciation or other indirect costs, to specific product development programs because these costs are deployed across multiple product development programs and, as such, are not separately classified. We use internal resources in combination with third-party CROs, including clinical monitors and clinical research associates, to manage our clinical trials, monitor subject enrollment and perform data analysis for many of our clinical trials. These employees work across multiple development programs and, therefore, we do not track their costs by program.

Table of Contents
The successful development and commercialization of our products or product candidates is highly uncertain. This is due to the numerous risks and uncertainties associated with product development and commercialization, including the uncertainty of:
● the scope, progress, outcome and costs of our clinical trials and other research and development activities;
● the timing, receipt and terms of any marketing approvals;
● the efficacy and potential advantages of our products or product candidates compared to alternative treatments, including any standard of care;
● the market acceptance of our products or product candidates; and
● significant and changing government regulation.
Any changes in the outcome of any of these variables with respect to the development of our product candidates in clinical and preclinical development could mean a significant change in the costs and timing associated with the development of these product candidates. For example, if the FDA or another regulatory authority were to require us to conduct clinical trials or other testing beyond those that we currently expect or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development of that product candidate. We anticipate that our research and development expenses will increase in the future as we support our continued development of our product candidates.
Selling and Marketing Expenses
Selling and marketing expenses consist primarily of salaries and related costs for personnel in selling and marketing functions as well as consulting, advertising and promotion costs.
General and Administrative Expenses
General and administrative expenses consist primarily of salaries and related costs, including stock-based compensation, for personnel in executive, finance, information technology, human resources and administrative functions. General and administrative expenses also include insurance, facility-related costs and professional fees for legal, patent, consulting and accounting and audit services.
Other Income (Expense)
Interest Expense . Interest expense is incurred on our debt. For the year ended December 31, 2023, our interest-bearing debt included the Barings Credit Facility ($82.5 million outstanding principal since August 2, 2023), the Convertible Notes ($37.5 million outstanding principal) and the notes payable under the MidCap Credit Facility ($25.0 million outstanding principal through August 2, 2023, no outstanding principal thereafter).
Change in Fair Value of Derivative Liabilities. In August 2023, in connection with entering into the Barings Credit Agreement, we identified an embedded derivative liability, which we are required to measure at fair value at inception and then at the end of each reporting period until the embedded derivative is settled. In 2019, in connection with the issuance of our Convertible Notes, we identified an embedded derivative liability, which we are required to measure at fair value at inception and then at the end of each reporting period until the embedded derivative is settled. The changes in fair value of these derivative liabilities are recorded through the consolidated statement of operations and comprehensive loss and are presented under the caption change in fair value of derivative liabilities.
Gains and Losses from Debt Extinguishment . In August 2023, we amended the Convertible Notes and accounted for the amendment as an extinguishment of debt in accordance with the guidance in Accounting Standards Codification Topic 470-50 Debt . Application of this accounting standard resulted in a gain on extinguishment. In August 2023, we also extinguished our obligations under the MidCap Credit Facility, resulting in a loss on extinguishment.

Research and development expenses were $61.1 million and $53.5 million for the years ended December 31, 2023 and 2022, respectively, reflecting an increase of $7.6 million year-over-year.
Within research and development expenses, expenses for clinical programs increased $7.2 million, unallocated expenses increased $0.8 million, and expenses for preclinical programs decreased $0.4 million.
For the year ended December 31, 2023, we incurred $18.4 million in direct research and development expenses for our products and product candidates compared to $11.2 million for the year ended December 31, 2022. The increase of $7.2 million is related to timing and conduct of our various clinical trials for our product candidates, including the initiation of the SOL-1 trial and the HELIOS trial, and development activities related to our preclinical programs.
We expect that clinical trial expenses for our product candidates will increase for 2024 and beyond, as we progress with the SOL-1 trial, the HELIOS trial, and the ongoing Phase 2 clinical trial of PAXTRAVA for the treatment of primary OAG or OHT, and as we initiate the planned SOL-2 trial of AXPAXLI in the first quarter of 2025, and as we, subject to favorable topline data from the HELIOS trial and agreement with the FDA, intend to commence a pivotal Phase 3 clinical trial of AXPAXLI for NPDR as a next step of clinical development.

The increase was primarily due to an increase of $3.1 million in personnel related costs including stock-based compensation, which was partially offset by a decrease in professional fees of $0.8 million and a decrease of $0.6 million in facility related and other costs.
We anticipate that our general and administrative expenses will increase in the future as we support our continued development and commercialization of our product candidates. We also anticipate that we will continue to incur increased accounting, audit, legal, intellectual property, regulatory, compliance, director and officer insurance costs as well as investor and public relations expenses associated with being a public company.
Other Income (Expense), Net
Interest Income . Interest income was $4.0 million and $0.8 million for the years ended December 31, 2023 and 2022, respectively, reflecting an increase of $3.2 million year-over-year. The increase is primarily due to a higher average balance of cash and cash equivalents held by us, and higher interest rates.
Interest Expense . Interest expense was $11.3 million and $7.0 million for the years ended December 31, 2023 and 2022, respectively, reflecting an increase of $4.3 million year-over-year. The increase is primarily due to higher balances of debt outstanding as a result of us drawing $82.5 million of debt under the Barings Credit Facility in August 2023, partially offset by us paying off the MidCap Credit Facility of $25.0 million in August 2023.
Change in Fair Value of Derivative Liabilities. We recognized a loss from the change in fair values of our derivative liabilities of $5.2 million for the year ended December 31, 2023, compared to a gain of $13.8 million for the year ended December 31, 2022. The net loss for 2023 comprises of a loss of $4.5 million from the change in the fair value of the derivative liability related to a conversion option embedded in the Convertible Notes and $0.9 million related to royalty fees under the Barings Credit Agreement that we paid or accrued, partially offset by a gain of $0.2 million from the change in the fair value of the derivative liability related to the Barings Credit Agreement. The net gain for 2022 results solely from the change in the fair value of the derivative liability related to the Conversion Option. We cannot predict how the fair value of the derivative liabilities will change in 2024 and beyond.
Gains and losses on extinguishment of debt, net. We recognized a gain from accounting for the modification of the Convertible Notes as an extinguishment of $14.9 million, partially offset by a loss from extinguishment of the MidCap Credit Facility of $0.7 million.
Comparison of the Years Ended December 31, 2022 and 2021

Liquidity and Capital Resources
Sources of Liquidity
We have financed our operations primarily through private placements of our preferred stock, public offerings and private placements of our common stock, borrowings under credit facilities, the private placements of our convertible notes, and sales of our products.
As of December 31, 2023, we had cash and cash equivalents of $195.8 million; outstanding notes payable with a principal amount of $82.5 million par value under the Barings Credit Facility, and outstanding Convertible Notes of $37.5 million par value plus total unpaid interest obligations related to the amounts outstanding under the Barings Credit Facility and the Convertible Notes of $11.7 million.
2023 Equity Financing
On December 18, 2023, we completed an underwritten public offering of 35,420,000 shares of our common stock at a public offering price of $3.25 per share, which includes 4,620,000 shares issued upon the exercise in full by the underwriters of their option to purchase additional shares of common stock in the public offering at the public offering price, less underwriting discounts and commissions. The total gross proceeds of the public offering were approximately $115.1 million, before deducting underwriting discounts and commissions and other offering expenses payable by us, resulting in net proceeds of approximately $107.7 million.
In 2023, we sold 1,514,926 shares of our common stock under our Open Market Sale Agreement with Jefferies, resulting in gross proceeds to us of $9.9 million, and net proceeds, after accounting for issuance costs, of $9.5 million.
2023 Debt Financing
On August 2, 2023, or the Closing Date, we entered into the Barings Credit Agreement, with Barings, as administrative agent, and the lenders party thereto, providing for the Barings Credit Facility, in the aggregate principal amount of $82.5 million, or the Total Credit Facility Amount. We borrowed the full amount of $82.5 million at closing and received proceeds of $77.3 million, after the application of an original issue discount and fees. Indebtedness under the Barings Credit Facility matures on the earlier to occur of (i) the six-year anniversary of the Closing Date and (ii) the date that is 91 days prior to the maturity date for our Convertible Notes.
Indebtedness under the Barings Credit Facility incurs interest at a Secured Overnight Financing Rate, or SOFR, based rate, subject to a minimum 1.50% floor, plus 6.75%. We are obligated to make interest payments on our indebtedness under the Barings Credit Facility on a monthly basis, commencing on the Closing Date; to pay annual administration fees; and to pay, on the maturity date, any principal and accrued interest that remains outstanding as of such date. In addition, we are obligated to pay a fee, which we refer to as the Royalty Fee, in an amount equal to the Total Credit Facility Amount, which amount shall be reduced by the total amount of interest and principal prepayment fees paid under the Barings Credit Agreement. We are required to pay the Royalty Fee in installments to Barings, for the benefit of the lenders, on a quarterly basis in an amount equal to three and one-half percent (3.5%) of the net sales of DEXTENZA occurring during such quarter, subject to the terms, conditions and limitations specified in the Barings Credit Agreement, until the Royalty Fee is paid in full. The Royalty Fee is due and payable upon a change of control of the company. In the event we complete a change of control transaction or sell all or substantially all of our assets on or prior to the twelve-month anniversary of the Closing Date, the Royalty Fee is subject to a reduction to an amount that is equal to (i) 20% of the Total Credit Facility Amount, in the event that a signed letter of intent evidencing such transaction was entered into by us on or prior to the date that is six months after the Closing Date and (ii) 30% of the Total Credit Facility Amount, in the event that a signed letter of intent evidencing such transaction was entered into by us after the date that is six months, but before the date that is twelve months, after the Closing Date. We may, at our option, prepay any or all of the Royalty Fee at any time without penalty. In connection with the Barings Credit Agreement, we have granted the lenders a first-priority security interest in all of our assets, including our intellectual property, subject to certain agreed-upon exceptions. The Barings Credit Agreement includes negative covenants restricting us from making payments to the holders of the Convertible Notes except in connection with a proposed conversion to equity and with respect to certain permitted expenses and requiring us to maintain a minimum liquidity amount of $20.0 million. The Barings Credit Agreement also includes customary affirmative and negative covenants.

In March 2019, we issued the Convertible Notes pursuant to a note purchase agreement, or the Purchase Agreement, with Cap 1 LLC, an affiliate of Summer Road LLC . Concurrently with entering into the Barings Credit Agreement, on August 2, 2023, we and the holders of the Convertible Notes extended the maturity of the Convertible Notes, which would otherwise have matured on March 1, 2026, to a date 91 days following the maturity of the indebtedness under the Barings Credit Facility. The Convertible Notes, as amended, accrue interest at an annual rate of 6% of its outstanding principal amount, payable at maturity, unless earlier converted, repurchased or redeemed. The holders of the Convertible Notes may convert all or part of the outstanding principal amount of their Convertible Notes into shares of our common stock, par value $0.0001 per share, prior to maturity and provided that no conversion results in a holder beneficially owning more than 19.99% of our issued and outstanding common stock. The conversion rate is initially 153.8462 shares of our common stock per $1,000 principal amount of the Convertible Notes, which is equivalent to an initial conversion price is $6.50 per share. The conversion rate is subject to adjustment in customary circumstances such as stock splits or similar changes to our capitalization. At our election, we may choose to make such conversion payment in cash, in shares of common stock, or in a combination thereof. Upon any conversion of any Convertible Note, we are obligated to make a cash payment to the holder of such Convertible Note for any interest accrued but unpaid on the principal amount converted. Upon the occurrence of a Corporate Transaction (as defined in the Convertible Notes), the holder of a Convertible Note is entitled, at such holder’s option, to convert all of the outstanding principal amount of the Convertible Note in accordance with the foregoing and receive an additional, “make-whole” cash payment in accordance with a table set forth in each Convertible Note. Upon the occurrence of a Corporate Transaction, each holder of a Convertible Note has the option to require us to repurchase all or part of the outstanding principal amount of such Convertible Note at a repurchase price equal to 100% of the outstanding principal amount of the Convertible Note to be repurchased, plus accrued and unpaid interest to, but excluding, the repurchase date. If the last reported sale price of the common stock has been at least 130% of the conversion rate then in effect for twenty of the preceding thirty trading days (including the last trading day of such period), we are entitled, at our option, to redeem all or part of the outstanding principal amount of the Convertible Notes, on a pro rata basis, at an optional redemption price equal to 100% of the outstanding principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the optional redemption date. The Purchase Agreement contains customary representations and warranties by us and the noteholder. The Purchase Agreement does not include any financial covenants. Our obligations under the Purchase Agreement and the Convertible Notes are subject to acceleration upon the occurrence of specified events of default, including a default or breach of certain contracts material to us and the delisting and deregistration of our common stock.
In connection with entering the Barings Credit Facility, in August 2023, we paid MidCap Financial Trust, as administrative agent, and our other lenders an aggregate of $26.2 million in satisfaction of our obligations under the MidCap Credit Facility.
2024 Private Placement
In February 2024, we sold 32,413,560 shares of our common stock at $7.52 per share and, in lieu of common stock to certain investors, pre-funded warrants to purchase up to an aggregate of 10,805,957 shares of our common stock at a price of $7.519 per pre-funded warrant for aggregate gross proceeds of approximately $325.0 million, before deducting placement agent fees and other offering expenses, under the 2024 Private Placement. Each pre-funded warrant has an exercise price of $0.001 per share, is currently exercisable and will remain exercisable until exercised in full.
Funding Requirements
We have a history of incurring significant operating losses. Our net losses were $80.7 million, $71.0 million, and $6.6 million for the years ended December 31, 2023, 2022 and 2021, respectively. As of December 31, 2023, we had an accumulated deficit of $697.6 million.
We expect to continue to incur losses in connection with our ongoing activities, particularly as we advance the clinical trials of our product candidates in development and increase our sales and marketing resources to support the commercialization of DEXTENZA and the potential launch of our product candidates, subject to receiving FDA approval.

Table of Contents
We anticipate we will incur substantial expenses if and as we:
● continue our ongoing clinical trials, including the SOL-1 trial of AXPAXLI for the treatment of wet AMD; our Phase 1 clinical trials of AXPAXLI for the treatment of wet AMD; the HELIOS trial of AXPAXLI for the treatment of NPDR; our Phase 2 clinical trial of PAXTRAVA for the treatment of OAG or OHT; our Phase 2 clinical trial of OTX-DED for the short-term treatment of the signs and symptoms of dry eye disease;
● continue to monitor subjects according to the applicable clinical trial protocols in our clinical trials that have been completed, including our clinical trial to evaluate DEXTENZA in pediatric subjects following cataract surgery;
● determine to initiate new clinical trials to evaluate our product candidates, including our planned SOL-2 trial of AXPAXLI for the treatment of wet AMD; our planned pivotal clinical trials of AXPAXLI for the treatment of NPDR; and, subject to our evaluation of strategic alternatives, possible pivotal clinical trials of PAXTRAVA for the reduction of IOP in patients with primary OAG or OHT;
● continue to commercialize DEXTENZA in the United States;
● continue to develop and expand our sales, marketing and distribution capabilities for DEXTENZA and any other products or product candidates we intend to commercialize;
● conduct or support research and development activities on, and seek regulatory approvals for, DEXTENZA and PAXTRAVA in specified Asian markets pursuant to our license agreement and collaboration with AffaMed Therapeutics Limited, or AffaMed;
● continue the research and development of our other product candidates;
● seek to identify and develop additional product candidates;
● seek marketing approvals for any of our product candidates that successfully complete clinical development;
● scale up our manufacturing processes and capabilities to support sales of commercial products, clinical trials of our product candidates and commercialization of any of our product candidates for which we obtain marketing approval, and expand our facilities to accommodate this scale up and any corresponding growth in personnel;
● renovate our existing facilities including research and development laboratories, manufacturing space and office space;
● maintain, expand and protect our intellectual property portfolio;
● expand our operational, financial, administrative and management systems and personnel, including personnel to support our clinical development, manufacturing and commercialization efforts;
● defend ourselves against legal proceedings, if any;
● make investments to improve our defenses against cybersecurity and establish and maintain cybersecurity insurance;
● increase our product liability and clinical trial insurance coverage as we expand our clinical trials and commercialization efforts; and
● continue to operate as a public company.

The amount and timing of these expenses determines our future capital requirements.
Based on our current operating plan, which includes estimates of anticipated cash inflows from DEXTENZA product sales and cash outflows from operating expenses and capital expenditures and reflects our observance of the minimum liquidity covenant of $20.0 million under the Barings Credit Agreement, we believe that our existing cash and cash equivalents as of December 31, 2023, plus the cash received from the 2024 Private Placement of our common stock in February 2024 of $325.0 million before deducting placement agent fees and other offering expenses, will enable us to fund our planned operating expenses, debt service obligations and capital expenditure requirements at least into 2028. We have based our estimates on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect.
Our future capital requirements will depend on many factors, including:
● the level of product sales from DEXTENZA and any additional products for which we obtain marketing approval in the future and the level of third-party reimbursement of such products;
● the costs of sales, marketing, distribution and other commercialization efforts with respect to DEXTENZA and any additional products for which we obtain marketing approval in the future, including cost increases due to inflation;
● the progress, costs and outcome of our ongoing and planned clinical trials of our product candidates, in particular AXPAXLI for the treatment of wet AMD and NPDR, and, subject to our evaluation of strategic alternatives, PAXTRAVA for the treatment of OAG or OHT;
● the scope, progress, costs and outcome of preclinical development and clinical trials of our other product candidates;
● the costs, timing and outcome of regulatory review of our product candidates by the FDA, the EMA or other regulatory authorities;
● the costs of scaling up our manufacturing processes and capabilities to support sales of commercial products, clinical trials of our product candidates and commercialization of any of our product candidates for which we obtain marketing approval and of expanding our facilities to accommodate this scale up and any corresponding growth in personnel;
● the extent of our debt service obligations and our ability, if desired, to refinance any of our existing debt on terms that are more favorable to us;
● the amounts we are entitled to receive, if any, as reimbursements for clinical trial expenditures, development, regulatory, and sales milestone payments, and royalty payments under our license agreement with AffaMed;
● the extent to which we choose to establish additional collaboration, distribution or other marketing arrangements for our products and product candidates;
● the costs and outcomes of any legal actions and proceedings;
● the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims; and
● the extent to which we acquire or invest in other businesses, products and technologies.
Until such time, if ever, as we can generate product revenues sufficient to achieve profitability, we expect to finance our cash needs through equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements, royalty agreements, and marketing and distribution arrangements. We do not have any committed external source of funds, although our license agreement with AffaMed provides for AffaMed’s reimbursement of certain clinical expenses incurred by us in connection with our collaboration and for our potential receipt of development

and sales milestone payments and royalty payments. To the extent that we raise additional capital through the sale of equity, preferred equity or convertible debt securities, our securityholders’ ownership interests will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our existing securityholders’ rights as holders or beneficial owners of our common stock. Debt financing and preferred equity financing, if available, may involve agreements that include 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 the Barings Credit Facility pursuant to which we have a total borrowing capacity of $82.5 million, which has been fully drawn down, may limit our ability to obtain additional debt or other financing. 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, products 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 or other arrangements when needed, we may be required to delay, limit, reduce or terminate our product development 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.

The table above includes our enforceable and legally binding obligations and future commitments at December 31, 2023, as well as obligations related to contracts that we are likely to continue, regardless of the fact that they may be cancelable at December 31, 2023. Some of the figures that we include in this table are based on management’s estimates and assumptions about these obligations, including their duration, and other factors. Because these estimates and assumptions are necessarily subjective, the amounts we will actually pay in future periods may vary from those reflected in the table.
We enter into contracts in the normal course of business to assist in the performance of our research and development activities and other services and products for operating purposes. These contracts generally provide for termination on notice, and therefore are cancelable contracts which are not included in contractual obligations and commitments.

Operating lease commitments represent payments due under our leases of office, laboratory and manufacturing space in Bedford, Massachusetts and certain office equipment under operating leases that expire in March 2024, July 2027, and July 2028.
The commitments under the Barings Credit Agreement represent repayment of principal only. Future payments of interest under the Barings Credit Agreement depends on the level of SOFR, and future payments of royalty fees depend on our future revenue from DEXTENZA, both of which cannot be estimated at this time.
The commitments under the Convertible Notes represent repayment of principal and payment of previously accrued interest at maturity in November 2029.
We have in-licensed a significant portion of our intellectual property from Incept, an intellectual property holding company, under an amended and restated license agreement, or the License Agreement, that we entered into with Incept in January 2012, which was most recently amended in September 2018. We are obligated to pay Incept a royalty equal to a low-single-digit percentage of net sales made by us or our affiliates of any products , devices, materials, or components thereof, or the Licensed Products, including or covered by Original IP (as defined in the License Agreement), excluding the Shape-Changing IP (as defined in the License Agreement), in the Ophthalmic Field of Use (as defined in the License Agreement). We are obligated to pay Incept a royalty equal to a mid-single-digit percentage of net sales made by us or our affiliates of any Licensed Products including or covered by Original IP, excluding the Shape-Changing IP, in the Additional Field of Use (as defined in the License Agreement). We are obligated to pay Incept a royalty equal to a low-single-digit percentage of net sales made by us or our affiliates of any Licensed Products including or covered by Incept IP (as defined in the License Agreement) or Joint IP (as defined in the License Agreement) in the field of drug delivery. Any sublicensee of ours also will be obligated to pay Incept a royalty on net sales of Licensed Products made by it and will be bound by the terms of the agreement to the same extent as we are. We are obligated to reimburse Incept for our share of the reasonable fees and costs incurred by Incept in connection with the prosecution of the patent applications licensed to us under the agreement. Our share of these fees and costs is equal to the total amount of such fees and costs divided by the total number of Incept’s exclusive licensees of the patent application. We have not included in the table above any payments to Incept under this license agreement as the amount, timing and likelihood of such payments are not known.
Off-Balance Sheet Arrangements
We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined in the rules and regulations of the Securities and Exchange Commission, such relationships with unconsolidated entities or financial partnerships, which are often referred to as structured finance or special purpose entities, established for the purpose of facilitating financing transactions that are not required to be reflected on our balance sheets.
Critical Accounting Policies and Significant Judgments and Estimates
Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America. The preparation of our consolidated financial statements and related disclosures requires us to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and the disclosure of contingent assets and liabilities in our consolidated financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, accrued research and development expenses and stock-based compensation. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
While our significant accounting policies are described in more detail in the notes to our consolidated financial statements appearing elsewhere in this annual report, we believe the following accounting policies to be most critical to the judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition
We recognize product revenue from the sales of DEXTENZA product.
In November 2018, the FDA approved DEXTENZA for the treatment of ocular pain following ophthalmic surgery. We entered into a limited number of arrangements with specialty distributors in the United States to distribute DEXTENZA. Accounting Standards Codification 606 – Revenue from Contracts with Customers , or Topic 606, applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance arrangements and financial instruments. Under Topic 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to be entitled to in exchange for those goods or services.
To determine revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the entity performs the following five steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies a performance obligation. We only apply the five-step model to arrangements that meet the definition of a contract with a customer under Topic 606, including when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services we transfer to the customer. At contract inception, once the contract is determined to be within the scope of Topic 606, we assess the goods or services promised within each contract, determines those that are performance obligations, and assesses whether each promised good or service is distinct. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. For a complete discussion of accounting for product revenue, see Product Revenue, Net (below).
Product Revenue, Net — We derive our product revenues from the sale of DEXTENZA in the United States to customers, which includes a limited number of specialty distributors, who then subsequently resell DEXTENZA to physicians, clinics and certain medical centers or hospitals. We also sell DEXTENZA directly to a small population of ASCs, based on individually negotiated direct distribution agreements. In addition, we enter into arrangements with health care providers and payors that provide for government mandated or privately negotiated rebates and chargebacks with respect to the purchase of DEXTENZA.
We recognize revenue on product sales when the customer obtains control of our product, which occurs at a point in time (upon delivery to the customer). We have determined that the delivery of DEXTENZA to our customers constitutes a single performance obligation. There are no other promises to deliver goods or services beyond what is specified in each accepted customer order. We have assessed the existence of a significant financing component in the agreements with our customers. The trade payment terms with our customers do not exceed one year and therefore we have elected to apply the practical expedient and no amount of consideration has been allocated as a financing component. Product revenues are recorded net of applicable reserves for variable consideration, including discounts and allowances.
Transaction Price, including Variable Consideration — Revenues from product sales are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which reserves are established. Components of variable consideration include trade discounts and allowances, product returns, government chargebacks, discounts and rebates, and other incentives, such as voluntary patient assistance, and other fee-for-service amounts that are detailed within contracts between us and our customers relating to our sale of DEXTENZA. These reserves, as detailed below, are based on the amounts earned, or to be claimed on the related sales, and are classified as reductions of accounts receivable or a current liability. These estimates take into consideration a range of possible outcomes which are probability-weighted in accordance with the expected value method in Topic 606 for relevant factors such as current contractual and statutory requirements, specific known market events and trends, industry data, and forecasted customer buying and payment patterns. Overall, these reserves reflect our best estimates of the amount of consideration to which we are entitled based on the terms of the respective underlying contracts.
The amount of variable consideration which is included in the transaction price may be constrained, and is included in the net sales price, only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized under the contract will not occur in a future period. Actual amounts of consideration ultimately received may differ from our estimates. If actual results in the future vary from our original estimates, we will adjust these estimates, which would affect net product revenue and earnings in the period such variances become known.
121
Table of Contents
Trade Discounts and Allowances —We compensate (through trade discounts and allowances) our customers for sales order management, data, and distribution services. However, we have determined such services received to date are not distinct from our sale of products to the customer and, therefore, these payments have been recorded as a reduction of revenue within the statement of operations and comprehensive loss, as well as a reduction to trade receivables, net on the consolidated balance sheets.
Product Returns — Consistent with industry practice, we generally offer customers a limited right of return for product that has been purchased from us in certain circumstances as further discussed below. We estimate the amount of our product sales that may be returned by our customers and record this estimate as a reduction of revenue in the period the related product revenue is recognized, as well as within accrued expenses and other current liabilities, in the accompanying consolidated balance sheets. We currently estimate product return reserves using available industry data and our own sales information, including our visibility into the inventory remaining in the distribution channel. We have received minimal returns to date and believe the returns of DEXTENZA will be minimal.
Government Chargebacks — Chargebacks for fees and discounts to qualified government healthcare providers represent the estimated obligations resulting from contractual commitments to sell products to qualified U.S. Department of Veterans Affairs hospitals and 340B entities at prices lower than the list prices charged to customers who directly purchase the product from us. The 340B Drug Discount Program is a U.S. federal government program created in 1992 that requires drug manufacturers to provide outpatient drugs to eligible health care organizations and covered entities at significantly reduced prices. Customers charge us for the difference between what they pay for the product and the statutory selling price to the qualified government entity. These allowances are established in the same period that the related revenue is recognized, resulting in a reduction of product revenue and trade receivables, net. Chargeback amounts are generally determined at the time of resale to the qualified government healthcare provider by customers, and we generally issue credits for such amounts within a few weeks of the customer’s notification to us of the resale. Allowances for chargebacks consist of credits that we expect to issue for units that remain in the distribution channel inventories at each reporting period-end that we expect will be sold to qualified healthcare providers, and chargebacks that customers have claimed, but for which we have not yet issued a credit.
Government Rebates — We are subject to discount obligations under state Medicaid programs and Medicare. These reserves 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 which is included in accrued expenses and other current liabilities on the consolidated balance sheets. For Medicare, we also estimate the number of patients in the prescription drug coverage gap for whom we will owe an additional liability under the Medicare Part D program. For Medicaid programs, we estimate the portion of sales attributed to Medicaid patients and record a liability for the rebates to be paid to the respective state Medicaid programs. Our liability for these rebates consists of invoices received for claims from prior quarters that have not been paid or for which an invoice has not yet been received, estimates of claims for the current quarter, and estimated future claims that will be made for product that has been recognized as revenue, but which remains in the distribution channel inventories at the end of each reporting period.
Purchaser/Provider Discounts and Rebates —We offer rebate payments for which ASCs, HOPDs and other prescribers qualify by meeting quarterly purchase volumes of DEXTENZA under our volume-based rebate program. We calculate rebate payment amounts due under this program quarterly, based on actual qualifying purchases and apply a contractual discount rate. In the third quarter of 2022, we implemented a separate off-invoice discount, or OID, rebate program whereby end- users receive the discounted price immediately upon purchase, rather than having to wait until the end of the quarter for a rebate payment. The OID amounts are generally determined at the time of resale by specialty distributors, or SDs, or direct sales to ASCs by us. We generally issue credits for such amounts within a few weeks of the SD’s notification to us of the resale. We include the OID on the invoice when we sell to an ASC directly. The calculation of the accrual for all rebates is based on an estimate of claims that we expect to receive associated with product that has been recognized as revenue but also remains in the distribution channel inventories at the end of each reporting period. The adjustments 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 which is included as an accrued expenses and other current liabilities for volume-based rebates and as a reduction of accounts receivable for OID rebates.
Other Incentives — Other incentives which we offer include voluntary patient assistance programs, such as the co-pay assistance program, which are intended to provide financial assistance to qualified commercially-insured patients with prescription drug co-payments required by payors. The calculation of the accrual for co-pay assistance is based on an estimate of claims and the cost per claim that we expect 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. The adjustments 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 which is included as accrued expenses and other current liabilities on the consolidated balance sheets.

The Convertible Notes allow the holders to convert all or part of the outstanding principal of their Convertible Notes into shares our common stock provided that no conversion results in a holder beneficially owning more than 19.99% of our issued and outstanding common stock. The entire embedded conversion option is required to be separated from the Convertible Notes and accounted for as a freestanding derivative instrument subject to derivative accounting. Therefore, the entire conversion option is bifurcated from the underlying debt instrument and accounted for and valued separately from the host instrument. The main input when determining the fair value of the Convertible Notes is the bond yield that pertains to the host instrument without the conversion option. The significant assumption used in determining the bond yield is the market yield movements of a comparable instrument issued as of the valuation date, which is assessed and updated each period. We measure the value of the embedded conversion option at its estimated fair value and recognize changes in the estimated fair value in other income (expense), net in the consolidated statements of operations and comprehensive loss during the period of change. The embedded conversion is recognized as a derivative liability in our consolidated balance sheet.
The Barings Credit Agreement contains an embedded obligation to pay the Royalty Fee, or the Royalty Fee Obligation, that meets the criteria to be bifurcated and accounted for separately from the Barings Credit Facility, or the Royalty Fee Derivative Liability. Royalty payments are estimated using a Monte Carlo simulation. The main inputs when determining the fair value of the Royalty Fee Derivative Liability are the amount and timing of our expected future revenue, the estimated volatility of these revenues, and the discount rate corresponding to the risk of revenue. We measure the value of the Royalty Fee Derivative Liability at its estimated fair value and recognize changes in the estimated fair value in other income (expense), net in the consolidated statements of operations and comprehensive loss during the period of change. The Royalty Fee Derivative Liability is recognized as a derivative liability in our consolidated balance sheet.
