NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.Operations

         The accompanying condensed consolidated financial statements of EyePoint Pharmaceuticals, Inc., a Delaware corporation (together with its subsidiaries, the “Company”), as of June 30, 2021 and for the three and six months ended June 30, 2021 and 2020 are unaudited. Certain information in the footnote disclosures of these financial statements has been condensed or omitted in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). These financial statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. In the opinion of management, these statements have been prepared on the same basis as the audited consolidated financial statements as of and for the year ended December 31, 2020, and include all adjustments, consisting only of normal recurring adjustments, that are necessary for the fair presentation of the Company’s financial position, results of operations, comprehensive loss and cash flows for the periods indicated. The preparation of financial statements in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) requires management to make assumptions and estimates that affect, among other things, (i) reported amounts of assets and liabilities; (ii) disclosure of contingent assets and liabilities at the date of the consolidated financial statements; and (iii) reported amounts of revenues and expenses during the reporting period. The results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the entire fiscal year or any future period.

         The Company is a pharmaceutical company committed to developing and commercializing innovative therapeutics to help improve the lives of patients with serious eye disorders. The Company’s pipeline leverages its proprietary Durasert^® technology for extended intraocular drug delivery including EYP-1901, a potential twice-yearly sustained delivery intravitreal anti-VEGF treatment initially targeting wet age-related macular degeneration (“wet AMD”), the leading cause of vision loss among people 50 years of age and older in the United States. The Company’s product candidate pipeline also includes YUTIQ^® 50, a potential twice-yearly treatment for non-infectious uveitis affecting the posterior segment of the eye, one of the leading causes of blindness. The Company also has two commercial products: YUTIQ^®, a once every three-year treatment for chronic non-infectious uveitis affecting the posterior segment of the eye, and DEXYCU^®, a single dose treatment for postoperative inflammation following ocular surgery.

Local drug delivery for treating ocular diseases is a significant challenge due to the effectiveness of the blood-eye barrier. This barrier makes it difficult for systemically-administered drugs to reach the eye in sufficient quantities to have a beneficial effect without causing unacceptable adverse side effects to other organs. The Company’s validated Durasert technology, which has already been included in four products approved for marketing by the U.S. Food and Drug Administration (“FDA”), is designed to provide consistent, sustained delivery of small molecule drugs over a period of months to years through a single intravitreal injection.

The Company’s lead product candidate, EYP-1901, combines a bioerodible formulation of its proprietary Durasert sustained-release technology with vorolanib, a tyrosine kinase inhibitor (“TKI”). The Company is currently evaluating EYP-1901 in a Phase 1 clinical trial as a potential twice-yearly sustained delivery intravitreal treatment for wet AMD. Current approved treatments for wet AMD require monthly or bi-monthly eye injections in a physician’s office, which can cause inconvenience and discomfort and often lead to reduced compliance and poor outcomes. On May 25, 2021, the Company announced the completion of the enrollment of the Phase 1 DAVIO clinical trial of EYP-1901 and expects initial data from trial in the fourth quarter of 2021.

The Company is also developing YUTIQ 50 as a potential twice-yearly intravitreal treatment for chronic non-infectious uveitis affecting the posterior segment of the eye. The Company has consulted with the FDA and identified a clinical pathway for a supplemental new drug application (“sNDA”) filing that the Company expects will involve a clinical trial of a small population. The Company expects to initiate the Phase 3 clinical trial for YUTIQ 50 by the end of this year.

The Company also has two commercial products, YUTIQ^® and DEXYCU^®, that are being sold directly in the U.S.  

YUTIQ^® (fluocinolone acetonide intravitreal implant) 0.18 mg for intravitreal injection, is a non-erodible intravitreal implant containing fluocinolone acetonide (“FA”) lasting for up to 36 months and is indicated for the treatment of chronic non-infectious uveitis affecting the posterior segment of the eye. This disease affects between 60,000 to 100,000 people each year in the U.S. causes approximately 30,000 new cases of blindness every year and

7

is the third leading cause of blindness. YUTIQ utilizes the Company’s proprietary Durasert^® sustained-release drug delivery technology platform.

DEXYCU^® (dexamethasone intraocular suspension) 9%, for intraocular administration, is indicated for the treatment of post-operative ocular inflammation, with the Company’s primary focus on its use immediately following cataract surgery as a single dose treatment. DEXYCU utilizes the Company’s proprietary Verisome^® drug-delivery technology.

The Company is also seeking to enhance its long-term growth potential by expanding EYP-1901 beyond wet AMD into diabetic retinopathy (“DR”) and retinal vein occlusion (“RVO”), both large and growing ocular disease areas. The Company also expects to potentially identify and advance additional product pipeline candidates through clinical and regulatory development. This may be accomplished through internal discovery efforts, potential research collaborations and/or in-licensing arrangements with partner molecules and potential acquisitions of additional ophthalmic products, product candidates or technologies that complement the Company’s current product portfolio.

Effects of the COVID-19 Coronavirus Pandemic

The ongoing COVID-19 coronavirus pandemic (the “Pandemic”) has had a material and adverse impact on the Company’s business, including as a result of measures that the Company, other businesses, and governments have taken and will possibly continue to take. This includes a significant impact on cash flows from expected revenues due to the closure of ambulatory surgery centers for DEXYCU and a significant reduction in physician office visits impacting YUTIQ in 2020. The ongoing Pandemic continued to have an adverse impact on the Company’s revenues, financial condition and cash flows in the first quarter and second quarter of 2021. Further, the future progression of the Pandemic and its effects on the Company’s business and operations are uncertain at this time. Depending on the future developments that are uncertain and difficult to predict, including new information that may emerge concerning the Pandemic, the Company’s revenues, financial condition and cash flows may be adversely affected in the future as well. The Company is continuously monitoring the Pandemic and its potential effect on the Company’s financial position, results of operations and cash flows. This uncertainty could have an impact in future periods on certain estimates used in the preparation of the Company’s periodic financial results, including reserves for variable consideration related to product sales, realizability of certain receivables, assessment for excess or obsolete inventory, and impairment of long-lived assets. Uncertainty around the extent and duration of the Pandemic, and any future related financial impact cannot be reasonably estimated at this time.

Liquidity

The Company had cash and cash equivalents of $127.6 million at June 30, 2021. The Company has a history of operating losses and has not had significant recurring cash inflows from revenue. The Company’s operations have been financed primarily from sales of its equity securities, issuance of debt and a combination of license fees, milestone payments, royalty income and other fees received from its collaboration partners. In the first quarter of 2019, the Company commenced the U.S. launch of its first two commercial products, YUTIQ and DEXYCU. However, the Company has not received sufficient revenues from its product sales to fund operations and the Company does not expect revenues from its product sales to generate sufficient funding to sustain its operations in the near-term. The Company expects to continue fulfilling its funding needs through cash inflows from revenue of YUTIQ and DEXYCU product sales, licensing and research collaboration transactions, additional equity capital raises and other arrangements. The Company believes that its cash and cash equivalents of $127.6 million at June 30, 2021, coupled with expected cash inflows from its product sales will enable the Company to fund its current and planned operations for at least the next twelve months from the date these consolidated financial statements were issued. Actual cash requirements could differ from management’s projections due to many factors, including the continued effect of the Pandemic on the Company’s business and the medical community, the timing and results of the Company’s clinical trials for EYP-1901, additional investments in research and development programs, the success of commercialization for YUTIQ and DEXYCU, the actual costs of these commercialization efforts, competing technological and market developments and the costs of any strategic acquisitions and/or development of complementary business opportunities.

Recently Adopted and Recently Issued Accounting Pronouncements

New accounting pronouncements are issued periodically by the Financial Accounting Standards Board (“FASB”) and are adopted by the Company as of the specified effective dates. Unless otherwise disclosed below, the

8

Company believes that recently issued and adopted pronouncements will not have a material impact on the Company’s financial position, results of operations and cash flows or do not apply to the Company’s operations.   

In May 2021, the FASB issued ASU No. 2021-04, Earnings Per Share (Topic 260), Debt— Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2021-04”): Issuer’s  Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. The amendments are designed to clarify an issuer’s accounting for certain modifications or exchanges of freestanding equity-classified written call options that remain equity-classified after modification or exchange. The ASU provides guidance on how an issuer would measure and recognize the effects of these transactions. The standard provides a principles-based framework to determine whether an issuer should recognize the modification or exchange as an adjustment to equity or an expense. ASU 2021-04 is effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. Early adoption is permitted, including adoption in interim or annual periods for which financial statements have not yet been issued. ASU 2021-04 will be effective for the Company in the first quarter of its fiscal year ending December 31, 2022. The Company is currently evaluating the impact the adoption of this update will have on its consolidated financial statements.

2. Summary of Significant Accounting Policies

Revenue Recognition

Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, Revenue from Contracts with Customers (“ASC 606”), the Company 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. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract, determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

Product sales, net — The Company sells YUTIQ and DEXYCU to a limited number of specialty distributors and specialty pharmacies (collectively the “Distributors”) in the U.S., with whom the Company has entered into formal agreements, for delivery to physician practices for YUTIQ and to hospital outpatient departments and ambulatory surgical centers for DEXYCU. The Company recognizes revenue on sales of its products when Distributors obtain control of the products, which occurs at a point in time, typically upon delivery. In addition to agreements with Distributors, the Company also enters into arrangements with healthcare providers, ambulatory surgical centers, and payors that provide for government mandated and/or privately negotiated rebates, chargebacks, and discounts with respect to the purchase of the Company’s products from Distributors.

Reserves for variable consideration — Product sales are recorded at the wholesale acquisition costs, net of applicable reserves for variable consideration. Components of variable consideration include trade discounts and allowances, provider chargebacks and discounts, payor rebates, product returns, and other allowances that are offered within contracts between the Company and its Distributors, payors, and other contracted purchasers relating to the Company’s product sales. These reserves, as detailed below, are based on the amounts earned, or to be claimed on the related sales, and are classified either as reductions of product revenue and accounts receivable or a current liability, depending on how the amount is to be settled. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the respective underlying contracts. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results in the future vary from the estimates, the Company adjusts these estimates, which would affect product revenue and earnings in the period such variances become known.

Distribution fees — The Company compensates its Distributors for services explicitly stated in the Company’s contracts and are recorded as a reduction of revenue in the period the related product sale is recognized.

Provider chargebacks and discounts — Chargebacks are discounts that represent the estimated obligations resulting from contractual commitments to sell products at prices lower than the list prices charged to the Company’s Distributors. These Distributors charge the Company for the difference between what they pay for the product and the Company’s contracted selling price. These reserves are established in the same period that the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability. Reserves for chargebacks consist of amounts that the Company expects to pay for units that remain in the distribution channel inventories at each reporting period-end that the Company expects will be sold under a contracted selling price, and chargebacks that Distributors have claimed, but for which the Company has not yet settled.

Government rebates — The Company is 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 condensed consolidated balance sheets. The Company’s 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.

Payor rebates — The Company contracts with certain private payor organizations, primarily insurance companies, for the payment of rebates with respect to utilization of its products. The Company estimates these rebates and records such estimates in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability.

Co-Payment assistance — The Company offers co-payment assistance to commercially insured patients meeting certain eligibility requirements. The calculation of the accrual for co-pay assistance is based on an estimate of claims and the cost per claim that the Company expects to receive associated with product that has been recognized as revenue.

Product returns — The Company generally offers a limited right of return based on its returned goods policy, which includes damaged product and remaining shelf life. The Company estimates the amount of its product sales that may be returned and records this estimate as a reduction of revenue in the period the related product revenue is recognized, as well as reductions to trade receivables, net on the condensed consolidated balance sheets.

License and collaboration agreement revenue — The Company analyzes each element of its license and collaboration arrangements to determine the appropriate revenue recognition. The terms of the license agreement may include payment to the Company of non-refundable up-front license fees, milestone payments if specified objectives are achieved, and/or royalties on product sales. The Company recognizes revenue from upfront payments at a point in time, typically upon fulfilling the delivery of the associated intellectual property to the customer.

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations.

The Company recognizes sales-based milestone payments as revenue upon the achievement of the cumulative sales amount specified in the contract in accordance with ASC 606-10-55-65. For those milestone payments which are contingent on the occurrence of particular future events, the Company determines that these need to be considered for inclusion in the calculation of total consideration from the contract as a component of variable consideration using the most-likely amount method. As such, the Company assesses each milestone to determine the probability and substance behind achieving each milestone. Given the inherent uncertainty associated with these future events, the Company will not recognize revenue from such milestones until there is a high probability of occurrence, which typically occurs near or upon achievement of the event.

When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component.

10

Applying the practical expedient in paragraph 606-10-32-18, the Company does not assess whether a significant financing component exists if the period between when the Company performs its obligations under the contract and when the customer pays is one year or less. None of the Company’s contracts contained a significant financing component as of June 30, 2021.

Royalties — The Company recognizes revenue from license arrangements with its commercial partners’ net sales of products. Such revenues are included as royalty income. In accordance with ASC 606-10-55-65, royalties are recognized when the subsequent sale of the commercial partner’s products occurs. The Company’s commercial partners are obligated to report their net product sales and the resulting royalty due to the Company typically within 60 days from the end of each quarter. Based on historical product sales, royalty receipts and other relevant information, the Company recognizes royalty income each quarter and subsequently determines a true-up when it receives royalty reports and payment from its commercial partners. Historically, these true-up adjustments have been immaterial.

Sale of Future Royalties — The Company has sold its rights to receive certain royalties on product sales. In the circumstance where the Company has sold its rights to future royalties under a royalty purchase agreement and also maintains limited continuing involvement in the arrangement (but not significant continuing involvement in the generation of the cash flows that are due to the purchaser), the Company defers recognition of the proceeds it receives for the sale of royalty streams and recognizes such unearned revenue as revenue under the units-of-revenue method over the life of the underlying license agreement. Under the units-of-revenue method, amortization for a reporting period is calculated by computing a ratio of the proceeds received from the purchaser to the total payments expected to be made to the purchaser over the term of the agreement, and then applying that ratio to the period’s cash payment.

Estimating the total payments expected to be received by the purchaser over the term of such arrangements requires management to use subjective estimates and assumptions. Changes to the Company’s estimate of the payments expected to be made to the purchaser over the term of such arrangements could have a material effect on the amount of revenues recognized in any particular period.

Research Collaborations — The Company recognizes revenue over the term of the statements of work under any funded research collaborations. Revenue recognition for consideration, if any, related to a license option right is assessed based on the terms of any such future license agreement or is otherwise recognized at the completion of the research collaborations.

Please refer to Note 3 for further details on the license and collaboration agreements into which the Company has entered and corresponding amounts of revenue recognized during the current and prior year periods.

Cost of sales, excluding amortization of acquired intangible assets — Cost of sales, excluding amortization of acquired intangible assets, consist of costs associated with the manufacture of YUTIQ and DEXYCU, certain period costs, product shipping and, as applicable, royalty expense. The inventory costs for YUTIQ include purchases of various components, the active pharmaceutical ingredient (“API”) and internal labor and overhead for the product manufactured in the Company’s Watertown, MA facility. The inventory costs for DEXYCU include purchased components, the API and third-party manufacturing and assembly.

For the three months ended June 30, 2021 and 2020, the Company accrued DEXYCU product revenue-based royalty expense of $648,000 and $99,000, respectively, as a component of cost of sales. For the six months ended June 30, 2021 and 2020, the Company accrued DEXYCU product revenue-based royalty expense of $1.1 million and $616,000, respectively, as a component of cost of sales, of which $0 and $400,000, respectively, were related to the earn-out payment equal to 20% of the $2 million upfront license fee received from Ocumension in February 2020 (See Note 3), as the payment of the partnering income in connection with the Company’s acquisition of Icon Bioscience, Inc. in March 2018 (the “Icon Acquisition”).

License and Collaboration Agreements and Royalty Income

Alimera

Pursuant to a licensing and development agreement, as amended (the “Amended Alimera Agreement”), Alimera Sciences, Inc. (“Alimera”) has a worldwide exclusive license to develop, make, market and sell ILUVIEN in return for royalties based on sales and patent fee reimbursements. Royalties income was $0 and $381,000 for the three months ended June 30, 2021 and 2020, respectively, and $0 and $1.2 million for the six months ended June 30, 2021 and 2020, respectively. Total revenue was $2,000 and $386,000 for the three months ended June 30, 2021 and 2020, respectively, and $15,000 and $1.2 million for the six months ended June 30, 2021 and 2020, respectively.

SWK Royalty Purchase Agreement

On December 17, 2020, the Company entered into a royalty purchase agreement (the “RPA”) with SWK Funding LLC (“SWK”). Under the RPA, the Company sold its right to receive royalty payments on future sales of products subject to the Amended Alimera Agreement for an upfront cash payment of $16.5 million. Except for the rights to the royalties, the Company retains all rights and obligations under the Amended Alimera Agreement, pursuant to which, Alimera owns worldwide rights to the Company’s Durasert technology in ILUVIEN for diabetic macular edema (“DME”) and rights for ILUVIEN (currently marketed by the Company as YUTIQ in the U.S.) for non-infectious posterior uveitis in Europe, the Middle East, and Africa (“EMEA”). Alimera has the sole rights to utilize the intellectual property developed under the Amended Alimera Agreement. There has been no intellectual property developed jointly by Alimera and the Company as part of the Amended Alimera Agreement. The Company cannot utilize the intellectual property for the indication licensed to Alimera in order to manufacture and sell ILUVIEN.

The Company’s ongoing efforts under the Amended Alimera Agreement will consist of continuing to maintain and enforce its patents as well as providing safety data and regulatory support as necessary. None of these obligations require significant efforts on the part of the Company with respect to the generation of sales in the market. The Company will only be required to expend more extensive efforts if litigation were to arise that requires the Company to protect its patents rights pursuant to the terms of the Amended Alimera Agreement. Historically, such a defense has not been required. Similarly, regulatory support and safety data is only provided on an ad-hoc basis depending on the regulatory requests, which has been minimal historically. It remains Alimera’s sole responsibility to manufacture, actively market and promote the products under the Amended Alimera Agreement to generate the sales, which ultimately generate the royalties to be paid to SWK.

The Company classified the proceeds received from SWK as deferred revenue, to be recognized as revenue under the units-of-revenue method over the life of the RPA because of the Company’s limited continuing involvement in the Amended Alimera Agreement. SWK has no recourse and the Company assumes no credit risk in event that Alimera fails to make a royalty payment. The Company must only forward all material correspondence from Alimera to SWK, including royalty reports, notices and any other correspondence with respect to royalties to SWK. SWK has the right to audit and inspect the books and records pertaining to net sales and royalties under the Amended Alimera Agreement. Neither the Company nor SWK has the unilateral ability to cancel the transaction. There is no cap or limitation on the royalties to be received by SWK in the future and its return will reflect all royalties paid by Alimera. Because the transaction was structured as a non-cancellable sale, the Company does not have significant continuing involvement in the generation of the cash flows due to SWK and there is no limitation on the rates of return to SWK, the Company recorded the total proceeds of $16.5 million as deferred revenue under royalty sale agreement. The deferred revenue is being recognized as revenue over the life of the RPA under the "units-of-revenue" method. Under this method, amortization for a reporting period is calculated by computing a ratio of the proceeds received from SWK to the payments expected to be made by Alimera to SWK over the term of the Amended Alimera Agreement, and then applying that ratio to the period’s cash payment.

The Company recognized $181,000 and $361,000 of royalty revenue related to the RPA for the three and six months ended June 30, 2021, in connection with the royalty payment of $583,000 and $1.2 million for the three and six months ended June 30, 2021 from Alimera to SWK, pursuant to the Amended Alimera Agreement. No revenue was recognized related to the RPA for the three and six months ended June 30, 2020. As of June 30, 2021, the Company had $1.0 million and $15.1 million as current and non-current deferred revenue recognized under royalty sale agreement, respectively. As of December 31, 2020, the Company classified $885,000 and $15.6 million as current and non-current deferred revenue recognized under royalty sale agreement, respectively.

Ocumension Therapeutics

In November 2018, the Company entered into an exclusive license agreement with Ocumension Therapeutics (“Ocumension”) for the development and commercialization of its three-year micro insert using the Durasert technology for the treatment of chronic non-infectious uveitis affecting the posterior segment of the eye (YUTIQ in the U.S.) in Mainland China, Hong Kong, Macau and Taiwan. The Company received a one-time upfront payment of $1.75 million from Ocumension and is eligible to receive up to (i) $7.25 million upon the achievement by Ocumension of certain prescribed development and regulatory milestones, and (ii) $3.0 million commercial sales-based milestones. In addition, the Company is entitled to receive mid-single digit sales-based royalties. Ocumension has also received a special approval by the Hainan Province People's Government to market this product for chronic, non-infectious posterior segment uveitis in the Hainan Bo Ao Lecheng International Medical Tourism Pilot Zone (“Hainan Pilot Zone”). In March 2019, the Company entered into a Memorandum of Understanding (“2019 MOU”), pursuant to which, the Company will supply product for the clinical trials and Hainan Pilot Zone use. Paralleling to Ocumension’s normal registration process of the product with the Chinese Regulatory Authorities, the 2019 MOU modified the Company’s entitlement to the development and regulatory milestones of up to $7.25 million under the license agreement to product supply milestones or development milestones, whichever comes first, totaling up to $7.25 million. In August 2019, the Company began shipping this product to Ocumension.

The Company was required to provide a fixed number of hours of technical assistance support to Ocumension at no cost, which support has been completed and no future performance obligation exists. Ocumension is responsible for all development, regulatory and commercial costs, including any additional technical assistance requested. Ocumension has a first right of negotiation for an additional exclusive license to the Company’s shorter-duration line extension candidate for this indication.

In August 2019, the Company received a $1.0 million development milestone payment from Ocumension triggered by the approval of its Investigational New Drug (“IND”) in China for this program. The IND allows the importation of finished product into China for use in a clinical trial to support regulatory filing.

In January 2020, the Company entered into an exclusive license agreement with Ocumension for the development and commercialization in Mainland China, Hong Kong, Macau and Taiwan of DEXYCU for the treatment of post-operative inflammation following ocular surgery. Pursuant to the terms of the license agreement, the Company received upfront payments of $2.0 million from Ocumension in February 2020 and will be eligible to receive up to (i) $6.0 million upon the achievement by Ocumension of certain prescribed development and regulatory milestones, and (ii) $6.0 million commercial sales-based milestones. In addition, the Company is entitled to receive mid-single digit sales-based royalties. In exchange, Ocumension will receive exclusive rights to develop and commercialize DEXYCU in Mainland China, Hong Kong, Macau and Taiwan, at its own cost and expense with the Company supplying product for clinical trials and commercial sale. In addition, Ocumension will receive a fixed number of hours of technical assistance support from the Company at no cost.

In August 2020, the Company entered into a Memorandum of Understanding (“2020 MOU”), pursuant to which, the Company received a one-time non-refundable payment of $9.5 million (the “Accelerated Milestone Payment”) from Ocumension as a full and final payment of the combined remaining development, regulatory and sales milestone payments under the Company’s license agreements with Ocumension for the treatment of chronic non-infectious uveitis affecting the posterior segment of the eye and for the treatment of post-operative inflammation following ocular surgery, respectively. Upon payment of the Accelerated Milestone Payment, the remaining $11.75 million in combined remaining development and sales milestone payments under the Company’s original license agreement with Ocumension upon the achievement by Ocumension of (i) remaining development and regulatory milestones of $6.25 million and commercial sales-based milestones of $3.0 million for the development and commercialization of its three-year micro insert using the Durasert technology for the treatment of chronic non-infectious uveitis affecting the posterior segment of the eye; and (ii) $6.0 million upon the achievement by Ocumension of certain prescribed development and regulatory milestones, and $6.0 million commercial sales-based milestones for the development and commercialization in Mainland China, Hong Kong, Macau and Taiwan of DEXYCU for the treatment of post-operative inflammation following ocular surgery, totaling up to $21.25 million, were permanently extinguished and will no longer be due and owed to the Company. In exchange, Ocumension also received exclusive rights to develop and commercialize YUTIQ and DEXYCU products under its own brand names in South Korea and other jurisdictions across Southeast Asia in Brunei, Burma (Myanmar), Cambodia, Timor-Leste, Indonesia, Laos, Malaysia, the Philippines, Singapore, Thailand and Vietnam, at its own cost and expense with the Company supplying product for clinical trials and commercial sale. The Company continues to be entitled to royalties on future product sales by Ocumension. In April 2021, Ocumension filed a New Drug Application

14

(“NDA”) for YUTIQ under Ocumension’s distinct name to Chinese regulatory authorities and it is under review. Ocumension has been granted approval to have its NDA submission reviewed based on the U.S. NDA data and the real world data Ocumension has collected from marketing the product in Hainan Pilot Zone.

Other than a fixed number of hours of technical assistance support to be provided at no cost by the Company, Ocumension is responsible for all development, regulatory and commercial costs, including any additional technical assistance requested. All technical assistance was provided during 2020. The Chief Executive Officer of Ocumension became a director of the Company starting December 31, 2020, pursuant to a Share Purchase Agreement pursuant to which the Company sold to Ocumension 3,010,722 shares of common stock, at which time, Ocumension became a related party of the Company.

During the three months ended June 30, 2021 and 2020, the Company recognized $91,000 and $0, respectively, related to additional technical assistance. During the six months ended June 30, 2021 and 2020, the Company recognized $360,000, related to additional technical assistance, and approximately $2.0 million of license and collaboration revenue, respectively.   

The Company recognized no sales-based royalty expense during the three months ended June 30, 2021 and 2020. The Company recognized $0 and $400,000 of accrued sales-based royalty expense during the six months ended June 30, 2021 and 2020, respectively, related to the earn-out payment equal to 20% of the $2.0 million upfront license fee received from Ocumension in February 2020, as the payment of the partnering income in connection with the Icon Acquisition in March 2018.   

Research Collaborations

The Company from time to time enters into funded agreements to evaluate the potential use of its technology systems for sustained release of third-party partner drug candidates. Consideration received is generally recognized as revenue over the term of the research collaborations. Revenue recognition for consideration, if any, related to a license option right is assessed based on the terms of any such future license agreement or is otherwise recognized at the completion of the research collaborations. No revenues recognized under research collaborations for each of the three months ended June 30, 2021 and 2020, and $60,000 and $15,000 for the six months ended June 30, 2021 and 2020, respectively. At June 30, 2021 and December 31, 2020, $0 and $60,000 deferred revenue was recorded for the research collaborations, respectively.

7. Leases

On May 17, 2018, the Company amended the lease for its headquarters in Watertown, Massachusetts. The original five-year lease for approximately 13,650 square feet of combined office and laboratory space was set to expire in April 2019. Under the amendment, the Company leased an additional 6,590 square feet of rentable area of the building, with a commencement date of September 10, 2018. The amendment extended the term of the lease for the combined space through May 31, 2025. On April 5, 2021, the Company further amended the lease to include an additional 1,409 square feet of rentable area of the building through May 31, 2025, with a commencement date of July 1, 2021. The landlord agreed to provide the Company a construction allowance of up to $670,750 to be applied toward the aggregate work completed on the total space. The Company has an option to further extend the term of the lease for one additional five-year period. Per the terms of the lease agreement, the Company does not have a residual value guarantee. The Company previously provided a cash-collateralized $150,000 irrevocable standby letter of credit as security for the Company’s obligations under the lease, which was extended through the period that is four months beyond the expiration date of the amended lease. The Company will also be required to pay its proportionate share of certain operating costs and property taxes applicable to the leased premises in excess of new base year amounts.

16

In July 2017, the Company leased approximately 3,000 square feet of office space in Basking Ridge, New Jersey under a lease term extending through June 2022, with two five-year renewal options at 95% of the then-prevailing market rates. In addition to base rent, the Company is obligated to pay its proportionate share of building operating expenses and real estate taxes in excess of base year amounts. In June 2018, the Company subleased an additional 1,381 square feet of adjoining space from Caladrius Biosciences, Inc. (“Caladrius”) through May 2022. The Chief Executive Officer of Caladrius was a director of the Company through June 2020. Per the terms of the lease and sublease agreements, the Company does not have any residual value guarantees.

The Company identified and assessed the following significant assumptions in recognizing its right-of-use (“ROU”) assets and corresponding lease liabilities:

• As the Company’s leases do not provide an implicit rate, the Company estimated the incremental borrowing rate in calculating the present value of the lease payments. The Company utilized the borrowing rate under its existing 5-year term loan facility (see Note 8) as the discount rate.

• Since the Company elected to account for each lease component and its associated non-lease components as a single combined component, all contract consideration was allocated to the combined lease component.

• The expected lease terms include noncancelable lease periods. Renewal option periods have not been included in the determination of the lease terms as they are not deemed reasonably certain of exercise.

• Variable lease payments, such as common area maintenance, real estate taxes and property insurance are not included in the determination of the lease’s ROU asset or lease liability.

As of June 30, 2021, the weighted average remaining term of the Company’s operating leases was 3.8 years and the lease liabilities arising from obtaining ROU assets reflect a weighted average discount rate of 12.5%.

Supplemental balance sheet information related to operating leases as of June 30, 2021 and December 31, 2020 are as follows (in thousands):

	June 30,		December 31,
	2021		2020
Other current liabilities - operating lease current portion	$	613	$	568
Operating lease liabilities – noncurrent portion		2,013		2,330
Total operating lease liabilities	$	2,626	$	2,898

Operating lease expense recognized related to ROU assets was $213,000, excluding $9,000 of variable lease costs, for each of the three months ended June 30, 2021 and 2020, and $427,000 related to ROU assets, excluding $18,000 of variable lease costs, during each of the six months ended June 30, 2021 and 2020, and were included in general and administrative expense in the Company’s statement of comprehensive loss. Cash paid for amounts included in the measurement of operating lease liabilities was $221,000 and $215,000 for the three months ended June 30, 2021 and 2020, respectively, and $442,000 and $430,000 for the six months ended June 30, 2021 and 2020, respectively.

The Company is a party to two finance leases for laboratory equipment. The equipment leases expire in December 2021 and December 2022, respectively.

17

Supplemental balance sheet information related to the finance lease as of June 30, 2021 and December 31, 2020 are as follows (in thousands):

	June 30,			December 31,
	2021			2020
Property and equipment, at cost	$	239		$	239
Accumulated amortization		(115	)		(52	)

8. Loan Agreements

Paycheck Protection Program Loan

On April 8, 2020, the Company applied to Silicon Valley Bank (the “SVB”) for a Paycheck Protection Program Loan (the “PPP Loan”) of $2.0 million that is administered by the U.S. Small Business Administration (the “SBA”), under the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”). On April 22, 2020, the PPP Loan was approved and the Company received the PPP Loan proceeds.

The PPP Loan bears interest at a fixed rate of 1.0% per annum and has a two-year term that matures on April 21, 2022. Monthly principal and interest are payable commencing on November 21, 2020, subject to possible partial

18

or full forgiveness and principal and interest payments can be deferred as described below, if the PPP Loan proceeds are used for covered payroll costs, rent and utility costs and the maintenance of employee and compensation levels.

The Paycheck Protection Program Flexibility Act of 2020 (the “PPP Flexibility Act”), enacted on June 5, 2020, amended the Paycheck Protection Program, among others, as follows: (i) extended the covered period from 8 weeks to the earlier of 24 weeks from the date the PPP Loan is originated and December 31, 2020, during which PPP funds needed to be expended in order to be forgiven. A borrower may submit a loan forgiveness application any time on or before the maturity date of the loan – including before the end of the covered period – if the borrower has used all of the loan proceeds for which the borrower is requesting forgiveness; (ii) at least 60% of PPP funds must be spent on payroll costs, with the remaining 40% available to spend on other eligible expenses; (iii) payments are deferred until the date on which the amount of forgiveness determined is remitted to the lender. If a borrower fails to seek forgiveness within 10 months after the last day of its covered period, then payments will begin on the date that is 10 months after the last day of the covered period. In addition, the PPP Flexibility Act modified the CARES Act by increasing the maturity date for loans made after the effective date from two years to a minimum maturity of five years from the date on which the borrower applies for loan forgiveness. Existing PPP loans made before the new legislation retain their original two-year term, but may be renegotiated between a lender and a borrower to match the 5-year term permitted under the PPP Flexibility Act.

The Company used all of the loan proceeds from the PPP Loan to pay expenses during the covered period that the Company believes were for eligible purposes. On September 25, 2020, the Company submitted an application to the SBA through SVB for full loan forgiveness. On June 19, 2021, the Company received notification from SVB that the PPP Loan of $2.0 million has been fully forgiven by the SBA, and that payment and all accrued interest of $24,000 thereon were remitted by the SBA to SVB on June 16, 2021. In connection with the full loan forgiveness, the Company recorded a gain on extinguishment of debt of approximately $2.1 million in the three and six months ended June 30, 2021.

CRG Term Loan Agreement

On February 13, 2019 (the “CRG Closing Date”), the Company entered into the CRG Loan Agreement among the Company, as borrower, CRG Servicing LLC, as administrative agent and collateral agent (the “Agent”), and the lenders party thereto from time to time (the “Lenders”), providing for a senior secured term loan of up to $60 million (the “CRG Loan”). On the CRG Closing Date, $35 million of the CRG Loan was advanced (the “CRG Initial Advance”). The Company utilized the proceeds from the CRG Initial Advance for the repayment in full of all outstanding obligations under its prior credit agreement (the “SWK Credit Agreement”) with SWK Funding LLC (“SWK”). In April 2019, the Company exercised its option to borrow an additional $15 million of the CRG Loan (the “CRG Second Advance”). The Company did not draw any additional funds under the CRG Loan by the final draw deadline of March 31, 2020.

The CRG Loan is due and payable on December 31, 2023 (the “Maturity Date”). The CRG Loan bears interest at a fixed rate of 12.5% per annum payable in arrears on the last business day of each calendar quarter. The Company is required to make quarterly, interest only payments until the Maturity Date. So long as no default has occurred and is continuing, the Company may elect on each applicable interest payment date to pay 2.5% of the 12.5% per annum interest as Paid In-Kind (“PIK”), whereby such PIK amount would be added to the aggregate principal amount and accrue interest at 12.5% per annum. During the six months ended June 30, 2021, no PIK amounts had been added to the principal balance of the CRG Loan. In addition, the Company is required to pay an upfront fee of 1.5% of amounts borrowed under the CRG Loan (excluding any paid-in-kind amounts), which is payable as amounts are advanced under the CRG Loan. The Company will also be required to pay an exit fee equal to 6% of (i) the aggregate principal amounts advanced and (ii) PIK amounts issued, under the CRG Loan Agreement. In connection with the CRG Initial Advance, a 1.5% financing fee of $525,000 and an expense reimbursement of $350,000 were deducted from the net borrowing proceeds. In connection with the CRG Second Advance, a 1.5% financing fee of $225,000 was deducted from the net borrowing proceeds.

Upon the occurrence of a bankruptcy-related event of default, all amounts outstanding with respect to the CRG Loan become due and payable immediately, and upon the occurrence of any other Event of Default (as defined in the CRG Loan Agreement), all or any amounts outstanding with respect to the CRG Loan may become due and payable upon request of the Agent or majority Lenders. Subject to certain exceptions, the Company is required to make mandatory prepayments of the CRG Loan with the proceeds of assets sales and in the event of a change of control of the Company. In addition, the Company may make a voluntary prepayment of the CRG Loan, in whole or in part, at any time. All mandatory and voluntary prepayments of the CRG Loan are subject to the payment of prepayment premiums as follows: (i) if prepayment occurs on or prior to December 31, 2019, an amount equal to

19

10% of the aggregate outstanding principal amount of the CRG Loan being prepaid, (ii) if prepayment occurs after December 31, 2019 and on or prior to December 31, 2020, 5% of the aggregate outstanding principal amount of the CRG Loan being prepaid, which was waived on December 17, 2020 when the Company paid $15.0 million against the CRG Loan obligations in connection with the consummation of the RPA agreement (see Note 3), and (iii) if prepayment occurs after December 31, 2020 and on or prior to December 31, 2021, an amount equal to 3% of the aggregate outstanding principal amount of the CRG Loan being prepaid. No prepayment premium is due on any principal prepaid after December 31, 2021. Certain of the Company’s existing and future subsidiaries are guaranteeing the obligations of the Company under the CRG Loan Agreement. The obligations of the Company under the CRG Loan Agreement and the guarantee of such obligations are secured by a pledge of substantially all of the Company’s and the guarantors’ assets.

The CRG Loan Agreement contains affirmative and negative covenants customary for financings of this type, including limitations on our and our subsidiaries’ abilities, among other things, to incur additional debt, grant or permit additional liens, make investments and acquisitions, merge or consolidate with others, dispose of assets, pay dividends and distributions and enter into affiliate transactions, in each case, subject to certain exceptions. In addition, the CRG Loan Agreement contains the following financial covenants requiring the Company and the Guarantors to maintain:

• liquidity in an amount which shall exceed the greater of (i) $5 million and (ii) to the extent the Company has incurred certain permitted debt, the minimum cash balance, if any, required of the Company by the creditors of such permitted debt; and

• annual minimum product revenue from YUTIQ and DEXYCU: (i) for the twelve-month period beginning on January 1, 2019 and ending on December 31, 2019, of at least $15 million, (ii) for the twelve-month period beginning on January 1, 2020 and ending on December 31, 2020, of at least $45 million, (iii) for the twelve-month period beginning on January 1, 2021 and ending on December 31, 2021, of at least $80 million and (iv) for the twelve-month period beginning on January 1, 2022 and ending on December 31, 2022, of at least $90 million.

In November 2019, CRG waived the financial covenant associated with the Company’s revenue derived from sales of its products, DEXYCU and YUTIQ, for the twelve-month period ending December 31, 2019. In October 2020, CRG (i) waived the financial covenant associated with the Company’s revenue derived from sales of its products, DEXYCU and YUTIQ, for the twelve-month period ending December 31, 2020 and (ii) amended the financial covenant associated with the Company’s minimum product revenue to $45 million from $80 million, for the twelve-month period ending December 31, 2021. In May 2021, CRG further amended the financial covenant associated with the Company’s minimum product revenue to $25 million from $45 million, for the twelve-month period ending December 31, 2021. There were no other material changes to the CRG Loan Agreement and the Company incurred no incremental charges for the issuance of the waivers.

The total debt discount related to the CRG Initial Advance was approximately $3.2 million and consisted of (i) the accrual of a $2.1 million exit fee; (ii) the $525,000 upfront fee; and (iii) $591,000 of legal and other transaction costs. This amount is being amortized as additional interest expense over the term of the Loan using the effective interest rate method.

The total debt discount related to the CRG Second Advance was approximately $1.1 million and consisted of (i) the accrual of a $900,000 exit fee; and (ii) the $225,000 upfront fee. This amount is being amortized as additional interest expense over the term of the Loan using the effective interest rate method.

On December 17, 2020, the Company paid $15.0 million against the CRG Loan obligations in connection with the consummation of the RPA agreement (see Note 3). This payment included (i) a $13.8 million principal portion of the CRG Loan (ii) the $828,000 Exit Fee, and (iii) accrued and unpaid interest of $378,000 through that date. In connection with the partial prepayment of the CRG Loan, the Company recorded a loss on partial extinguishment of debt of $905,000 in the year ended December 31, 2020, associated with the write-off of the remaining balance of unamortized debt discount related to the partial prepayment of the CRG Loan.

Amortization of debt discount under the CRG Loan totaled $153,000 and $177,000 for the three months ended June 30, 2021 and 2020, respectively, and $300,000 and $348,000 for the six months ended June 30, 2021 and 2020, respectively.

10. Share-Based Payment Awards

Equity Incentive Plan

The 2016 Long-Term Incentive Plan (the “2016 Plan”), approved by the Company’s stockholders on December 12, 2016 (the “Adoption Date”), provides for the issuance of up to 300,000 shares of  the Company’s common stock reserved for issuance under the 2016 Plan plus any additional shares of the Company’s common stock that were available for grant under the 2008 Incentive Plan (the “2008 Plan”) at the Adoption Date or would otherwise become available for grant under the 2008 Plan as a result of subsequent termination or forfeiture of awards under the 2008 Plan.

In January 2019, the Company expanded the terms of its annual stock option grants to include vesting ratable monthly over four years, or with 25% vesting after one year followed by ratable monthly vesting over three years. Previously, the Company’s option grants generally had ratable annual vesting over three years, or 1-year cliff vesting. Nonemployee awards are granted similar to the Company’s employee awards. All option grants have a 10-year term. Options to purchase a total of 170,283 shares of the Company’s common stock vested during the six months ended June 30, 2021. Starting February 2021, the Company (i) ceased vesting ratable monthly over four years and (ii) retained 25% vesting after one year followed by ratable monthly vesting over the remaining three years.

In determining the grant date fair value of option awards during the six months ended June 30, 2021, the Company applied the Black-Scholes option pricing model based on the following key assumptions:

Option life (in years)	4.75 - 6.08
Stock volatility	72.5% - 83.07%
Risk-free interest rate	0.42% - 1.18%
Expected dividends	0.0%

Time-Vested Restricted Stock Units

Time-vested restricted stock unit awards (“RSUs”) issued to date under the 2016 Plan generally vest on a ratable annual basis over 3 years. The related stock-based compensation expense is recorded over the requisite service period, which is the vesting period. The fair value of all time-vested RSUs is based on the closing share price of the Company’s common stock on the date of grant.

The following table provides a reconciliation of RSU activity under the 2016 Plan for the six months ended June 30, 2021:

				Weighted
	Number of			Average
	Restricted			Grant Date
	Stock Units			Fair Value
Nonvested at January 1, 2021		149,004		$	13.85
Granted		227,141			13.06
Vested		(80,909	)		14.61
Forfeited		(4,319	)		11.72
Nonvested at June 30, 2021		290,917		$	13.05

At June 30, 2021, the weighted average remaining vesting term of the RSUs was 1.51 years.

Deferred Stock Units

There were no non-vested deferred stock units (“DSUs”) issued and outstanding to the Company’s non-executive directors at each of June 30, 2021 and December 31, 2020, respectively. Each DSU vests one year from the date of grant. Subsequent to vesting, the DSUs will be settled in shares of the Company’s common stock upon the earliest to occur of (i) each director’s termination of service on the Company’s Board of Directors and (ii) the occurrence of a change of control as defined in the award agreement. At June 30, 2021, there were no vested DSUs that have not been settled in shares of the Company’s common stock.

Employee Stock Purchase Plan

On June 25, 2019, the Company’s stockholders approved the adoption of the EyePoint Pharmaceuticals, Inc. 2019 Employee Stock Purchase Plan (the “ESPP”) and authorized up to 110,000 shares of common stock reserved for issuance to participating employees. At the Company’s Annual Meeting of Stockholders held on June 22, 2021, the Company’s stockholders approved an amendment to the ESPP to increase the number of shares authorized for issuance by 250,000 shares. The ESPP allows qualified participants to purchase the Company’s common stock twice a year at 85% of the lesser of the average of the high and low sales price of the Company’s common stock on (i) the first trading day of the relevant offering period and (ii) the last trading day of the relevant offering period. The number of shares of the Company’s common stock each employee may purchase under this plan, when combined with all other employee stock purchase plans, is limited to the lower of an aggregate fair market value of $25,000 during each calendar year, or 5,000 shares of the Company’s common stock in any one offering period. The Company has maintained consecutive six-month offering periods since August 1, 2019. As of June 30, 2021, 27,713 shares of the Company’s common stock were issued pursuant to the ESPP.

23

The Company estimated the fair value of the option component of the ESPP shares at the date of grant using a Black-Scholes valuation model. During the three and six months ended June 30, 2021, the compensation expense from ESPP shares was immaterial.  

Stock-Based Compensation Expense

The Company’s consolidated statements of comprehensive loss included total compensation expense from stock-based payment awards for the three and six months ended June 30, 2021 and 2020, respectively, as follows (in thousands):

	Three Months Ended June 30,					Six Months Ended June 30,
	2021		2020			2021		2020
Compensation expense included in:
Research and development	$	255	$	(49	)	$	518	$	214

General and administrative		684		643			1,169		1,288
	$	1,180	$	735		$	2,168	$	1,895

At June 30, 2021, there was approximately $10.7 million of unrecognized compensation expense related to outstanding equity awards under the 2016 Plan, the 2008 Plan, the inducement awards and the ESPP that is expected to be recognized as expense over a weighted-average period of approximately 1.64 years.

11.License Agreement

Equinox Science, LLC

In February 2020, the Company entered into an Exclusive License Agreement with Equinox Science, LLC (“Equinox”), pursuant to which Equinox granted the Company an exclusive, sublicensable, royalty-bearing right and license to certain patents and other Equinox intellectual property to research, develop, make, have made, use, sell, offer for sale and import the compound vorolanib and any pharmaceutical products comprising the compound for the prevention or treatment of age-related macular degeneration, diabetic retinopathy and retinal vein occlusion using our proprietary localized delivery technologies, in each case, throughout the world except China, Hong Kong, Taiwan and Macau.

In consideration for the rights granted by Equinox, the Company (i) made a one time, non-refundable, non-creditable upfront cash payment of $1.0 million to Equinox in February 2020, and (ii) agreed to pay milestone payments totaling up to $50 million upon the achievement of certain development and regulatory milestones, consisting of (a) completion of a Phase II clinical trial for the compound or a licensed product, (b) the filing of a new drug application or foreign equivalent for the compound or a licensed product in the United States, European Union or United Kingdom and (c) regulatory approval of the compound or a licensed product in the United States, European Union or United Kingdom.

The Company also agreed to pay Equinox tiered royalties based upon annual net sales of licensed products in the specified territory. The royalties are payable with respect to a licensed product in a particular country in the specified territory on a country-by-country and licensed product-by-licensed product basis until the later of (i) twelve years after the first commercial sale of such licensed product in such country and (ii) the first day of the month following the month in which a generic product corresponding to such licensed product is launched in such country. The royalty rates range from the high-single digits to low-double digits depending on the level of annual net sales. The royalty rates are subject to reduction during certain periods when there is no valid patent claim that covers a licensed product in a particular country.

The Company recorded $0 and $1.0 million of R&D expense for the three and six months ended June 30, 2020, respectively, due to the early stage of its preclinical drug development studies. No additional charge was recorded for the three and six months ended June 30, 2021.

12.Fair Value Measurements

The following tables summarize the Company’s assets carried at fair value measured on a recurring basis at June 30, 2021 and December 31, 2020 by valuation hierarchy (in thousands):

	June 30, 2021
			Quoted prices in		Significant other		Significant
	Total Carrying		active markets		observable inputs		unobservable inputs
Description	Value		(Level 1)		(Level 2)		(Level 3)

	$	23,538	$	23,538	$	—	$	—

Financial instruments that potentially subject the Company to concentrations of credit risk have historically consisted principally of cash and cash equivalents. At June 30, 2021 and December 31, 2020, substantially all of the Company’s interest-bearing cash equivalent balances were concentrated in one U.S. Government institutional money market fund that has investments consisting primarily of U.S. Government Agency debt, U.S. Treasury Repurchase Agreements and U.S. Government Agency Repurchase Agreements. These deposits may be redeemed upon demand and, therefore, generally have minimal risk. The Company’s cash equivalents are classified within Level 1 on the basis of valuations using quoted market prices.   

The carrying amounts of accounts receivable, accounts payable and accrued expenses approximate fair value because of their short-term maturity.

The fair value of the Company’s CRG Loan is determined using a discounted cash flow analysis based on market rates for observable similar instruments as of the condensed consolidated balance sheet dates. Accordingly, the fair value of the CRG Loan is categorized as Level 2 within the fair value hierarchy. At June 30 2021, the fair value of the CRG Loan was approximately $38.4 million, and the carrying value of the CRG Loan was approximately $38.5 million, and consisted of $36.2 million of its carrying amount as reported in long-term debt, and $2.3 million of debt exit fee as reported in other long-term liabilities of the condensed consolidated balance sheet, respectively. At December 31, 2020, the fair value of the CRG Loan was approximately $38.0 million, and the carrying value of the CRG Loan was approximately $38.3 million, and consisted of $36.0 million of its carrying amount as reported in long-term debt, and $2.3 million of debt exit fee as reported in other long-term liabilities of the condensed consolidated balance sheet, respectively.

13. Contingencies

U.S. Securities and Exchange Commission Subpoena

The Company previously disclosed that on May 14, 2020 it had received a subpoena from the Division of Enforcement of the SEC seeking production of certain documents and information on topics including product sales and demand, revenue recognition and accounting in relation to product sales, product sales and cash projections, and related financial reporting, disclosure and compliance matters. On May 4, 2021, the Company was advised by the SEC Division of Enforcement that it has concluded its investigation of the Company and that, based on the information it has to date, the Enforcement Division does not intend to recommend an enforcement action against the Company.

14. Net Loss per Share

Basic net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding during the period. For periods in which the Company reports net income, diluted net income per share is determined by adding to the basic weighted average number of common shares outstanding the total number of dilutive common equivalent shares using the treasury stock method, unless the effect is anti-dilutive. Potentially dilutive shares were not included in the calculation of diluted net loss per share for each of the three and six months ended June 30, 2021 and 2020 as their inclusion would be anti-dilutive.

Potential common stock equivalents excluded from the calculation of diluted earnings per share because the effect would have been anti-dilutive were as follows:

	Six Months Ended June 30,
	2021		2020
Stock options		2,099,810		1,367,235
ESPP		10,793		9,742
Warrants		48,683		48,683
Restricted stock units		290,917		146,352

Our Business

Overview

We are a pharmaceutical company committed to developing and commercializing innovative therapeutics to help improve the lives of patients with serious eye disorders. Our pipeline leverages our proprietary Durasert^® technology for extended intraocular drug delivery including EYP-1901, a potential twice-yearly sustained delivery intravitreal anti-VEGF treatment initially targeting wet age-related macular degeneration (“wet AMD”), the leading cause of vision loss among people 50 years of age and older in the United States. Our product candidate pipeline also includes YUTIQ^® 50, a potential twice-yearly treatment for non-infectious uveitis affecting the posterior segment of the eye, one of the leading causes of blindness. We also have two commercial products: YUTIQ^®, a once every three-year treatment for chronic non-infectious uveitis affecting the posterior segment of the eye, and DEXYCU^®, a single dose treatment for postoperative inflammation following ocular surgery.

28

Recent Developments

• Underlying customer demand and distributor purchases by specialty distributors and specialty pharmacies (collectively, the “Distributors”) of both YUTIQ and DEXYCU was negatively impacted beginning in the first and especially the second quarter of 2020 due to shutdowns associated with the Pandemic in the U.S. A modest return of customer demand began in June 2020 which contributed to sequential product sales growth in the third and fourth quarters of 2020, and Pandemic-related restrictions on elective surgeries and physician office visits were largely removed during the first and second quarters of 2021.  However, the future progression of the Pandemic and its effects on our business and operations are uncertain at this time. Depending on the future developments that are uncertain and difficult to predict, including new information that may emerge concerning the Pandemic, our customer demand may be adversely affected in the future as well. During the Pandemic, our sales organization has continued to call on physician offices, though at a reduced frequency. There have been no disruptions to the supply chains for YUTIQ and DEXYCU during the Pandemic and we continue to produce finished product for commercial sale.

• In February 2021, we sold 10,465,000 shares of common stock in an underwritten public offering at a price of $11.00 per share, including the exercise in full by the underwriters of their option to purchase up to 1,365,000 additional shares of our common stock. The gross proceeds of the offering are approximately $115.1 million. Underwriter discounts and commissions and other share issue costs totaled approximately $7.2 million.

• In a press release dated April 7, 2021, our Asia partner, Ocumension, announced that the new drug application (“NDA”) for OT-401 (YUTIQ) had been accepted by the National Medical Products Administration of the People’s Republic of China (“NMPA”). Ocumension reported that YUTIQ is its first ophthalmic drug for which an NDA has been accepted by the NMPA and is also the first sustained-release micro-insert submitted for NDA approval in mainland China that has a controlled release rate for up to 36 months. Ocumension’s press release also announced that this is the first time the NMPA has accepted an NDA based on real world study data.

• In June 2021, we received notification from Silicon Valley Bank (“SVB”) that the Paycheck Protection Program Loan (“PPP Loan”) of $2.0 million has been fully forgiven by the U.S. Small Business Administration (“SBA”), and that payment and all accrued interest thereon were remitted by the SBA to SVB on June 16, 2021.

• In June 2021, we announced that we had joined the Russell 2000^® and the Russell 3000^® indices.

• In July 2021, we announced that the American Medical Association created a new Category III Current Procedural Terminology (CPT®) Code to describe the injection of medicines like DEXYCU®.  The code, OX78T, is for the administration of a drug into the posterior chamber of the anterior segment of the eye and becomes effective January 1, 2022.  Once implemented, it may provide an opportunity for an additional reimbursement pathway for the administration of DEXYCU, in addition to the pass-through payment for the drug itself.

• In July 2021, we announced that we expect to receive a nine month extension of separate payment for DEXYCU, which would otherwise expire on March 31, 2022, with the end of the drug’s pass-through status.  The announcement was based on the fiscal year (FY) 2022 Medicare Hospital Outpatient Prospective Payment System (OPPS) proposed rule.  The rule includes a proposal to extend the period of separate payment for select pass-through drugs and devices that have their pass-through status scheduled to expire between December 31, 2021 and September 30, 2022, including DEXYCU.  CMS proposes to extend the period of separate payment for these therapies beyond the expiration of pass-through status in light of the COVID-19 public health emergency.  The proposal is subject to a public comment period and may be either adopted as proposed, modified, or withdrawn in the FY 2022 OPPS final rule, which is anticipated to be released in November 2021.

• In August 2021, we announced the establishment of our Executive Scientific Advisory Board with prestigious members made up of some of the leading retinal surgeons in the world and chaired by Dr. Carl Regillo MD, FACS, Chief of the Retina Service at Wills Eye Hospital.

29

R&D Highlights

• In January 2021, we dosed our first patient in our Phase 1 DAVIO clinical trial for EYP-1901.

• In May 2021, studies of DEXYCU were presented in two separate poster sessions at the Association for Research in Vision and Ophthalmology (“ARVO”) Annual meeting.

• In May 2021, we announced the completion of enrollment in our Phase 1 DAVIO clinical trial of EYP-1901 for the potential treatment of Wet AMD.

• In July 2021, we reported positive 30-day safety results for all cohorts from the DAVIO clinical trial.  Key safety observations through at least 30-Day post-dosing follow-up for all patients include: (i) No serious adverse events (SAEs), ocular or systemic, (ii) no reported adverse events (AEs) related to significant intraocular inflammation, best-corrected visual acuity (BCVA) reduction, or elevation of intraocular pressure (IOP) and (iii) no events of endophthalmitis, retinal detachment or migration into the anterior chamber.

• In July 2021, DEXYCU was presented in three separate oral presentations, one poster session and a video symposium at the American Society of Cataract and Refractive Surgery (ASCRS) Annual Meeting.

Critical Accounting Policies and Estimates

The preparation of consolidated financial statements in conformity with GAAP requires that we make certain estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. We base our estimates, judgments and assumptions on historical experience, anticipated results and trends, and on various other factors that we believe are reasonable under the circumstances at the time. By their nature, these estimates, judgments and assumptions are subject to an inherent degree of uncertainty. Actual results may differ from our estimates under different assumptions or conditions. In our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, we set forth our critical accounting policies and estimates, which included revenue recognition, reserves for variable consideration associated with our commercial revenue and recognition of expense in outsourced clinical trial agreements. See Note 2 of the notes to our unaudited condensed consolidated financial statements contained in this quarterly report on Form 10-Q for a description of our accounting policies and estimates for reserves for variable consideration related to product sales.

Product Sales, net

Product sales, net represents the gross sales of YUTIQ and DEXYCU less provisions for product sales allowances. Product sales, net increased by $5.0 million to $8.7 million for the three months ended June 30, 2021 compared to $3.7 million for the three months ended June 30, 2020.  Product sales during 2020 were negatively impacted due to shutdowns associated with the Pandemic in the U.S.  Although we did see a modest return of customer demand for both products in the third and fourth quarters of 2020, as Pandemic-related restrictions on elective surgeries and physician office visits were largely removed during the first and second quarters of 2021, the future progression of the Pandemic and its effects on our business and operations are uncertain at this time. Depending on the future developments that are uncertain and difficult to predict, including new information that may emerge concerning the Pandemic, our customer demand may be adversely affected in the future as well. Please see the Recent Development section for more information on the impact of the Pandemic on, among other things, our product sales.

License and collaboration agreement

License and collaboration agreement revenues increased by $59,000, or 169%, to $94,000 for the three months ended June 30, 2021 compared to $35,000 for the three months ended June 30, 2020. This increase was attributable primarily to our ongoing collaboration with Ocumension.

Royalty Income

Royalty income decreased by $200,000, or 52%, to $181,000 for the three months ended June 30, 2021 compared to $381,000 for the three months ended June 30, 2020. The decrease was attributable to the impact of the royalty monetization agreement with SWK Holdings that grants to SWK all future royalty payments under the Amended Alimera Agreement beginning with Q4 2020 for a one-time payment of $16.5 million.  Due to the accounting treatment for this agreement (see the Revenue Recognition section), we recognize a non-cash portion of

31

deferred revenue as Alimera pays royalties to SWK beginning in the first quarter of 2021 (see Note 3). We expect lower royalty revenue related to the royalty monetization agreement in 2021 compared to 2020.

Cost of Sales, Excluding Amortization of Acquired Intangible Assets

Cost of sales, excluding amortization of acquired intangible assets, increased by $1.4 million, or 284%, to $1.9 million for the three months ended June 30, 2021 from $502,000 for the three months ended June 30, 2020. This increase was primarily attributable to increased costs associated with higher product sales, primarily costs of goods and royalties, due to higher DEXYCU product mix.

Research and Development

Research and development expenses increased by $2.3 million, or 71%, to $5.6 million for the three months ended June 30, 2021 from $3.3 million for the same period in the prior year. This increase was attributable primarily to (i) $1.7 million in increased personnel related costs due to expansion of our clinical and research organization and (ii) approximately $840,000 of increased clinical costs, primarily related to our EYP-1901 Phase 1 study, partially offset by a decrease of approximately $94,000 in investigator-initiated studies and other medical affairs related costs.

Sales and Marketing

Sales and marketing expenses increased by $570,000, or 9%, to $6.7 million for the three months ended June 30, 2021 from $6.1 million for the same period in the prior year.  This increase was primarily attributable to $828,000 in commissions due to our commercial partner for DEXYCU, partially offset by approximately $212,000 in decreased net personnel related expenses, primarily due to the reduction in DEXYCU KAMs that occurred in Q2 2020.

General and Administrative

General and administrative expenses increased by $392,000, or 8%, to $5.2 million for the three months ended June 30, 2021 from $4.8 million for the same period in the prior year. This increase was attributable primarily to (i) $180,000 in personnel related expenses and (ii) $152,000 in consulting, investor relations and other spending initiatives, partially offset by a $65,000 decrease in legal, audit and other professional services,

Amortization of Acquired Intangible Assets

Amortization of acquired intangible assets totaled $615,000 for both the three months ended June 30, 2021 as well as the same period in the prior year.  This amount was attributable to the DEXYCU product intangible asset that resulted from the Icon Acquisition (see Note 5).  

Interest (Expense) Income

Interest expense totaled $1.4 million for the three months ended June 30, 2021, which included $153,000 of amortization of debt discount and $0 of non-cash payment-in-kind interest expense all related to the CRG Debt. We incurred lower interest expense due to the $13.7 million partial principal paydown in Q4-2020 on the CRG term loan.  Interest expense in the three months ended June 30, 2020 was $1.8 million which included $177,000 of amortization of debt discount and $324,000 of non-cash payment-in-kind interest expense.

Interest income from amounts invested in an institutional money market fund decreased to $5,000 for the three months ended June 30, 2021 compared to $8,000 in the prior year quarter, due primarily to higher money market interest rates in the prior year quarter. At the start of the Pandemic, money market rates fell substantially beginning March 2020, current interest earned is therefore low, despite our increased cash balance. Other income for the three months ended June 30, 2021 is $275,000 from a tax refund related to FY2020.

Gain on Extinguishment of Debt

Forgiveness by the SBA of our PPP Loan resulted in a gain on extinguishment of debt, which consisted of approximately (i) $2.0 million of principal and (ii) $24,000 of interest (see Note 8).

Product Sales, net

Product sales, net represents the gross sales of YUTIQ and DEXYCU less provisions for product sales allowances. Product sales, net increased by $7.1 million to $15.5 million for the six months ended June 30, 2021 compared to $8.4 million for the six months ended June 30, 2020.  Product sales during 2020 were negatively impacted due to shutdowns associated with the Pandemic in the U.S.  Although we did see a modest return of customer demand for both products in the third and fourth quarters of 2020, as Pandemic-related restrictions on elective surgeries and physician office visits were largely removed during the first and second quarters of 2021, the future progression of the Pandemic and its effects on our business and operations are uncertain at this time. Depending on the future developments that are uncertain and difficult to predict, including new information that may emerge concerning the Pandemic, our customer demand may be adversely affected in the future as well. Please see the Recent Development section for more information on the impact of the Pandemic on, among other things, our product sales.

License and collaboration agreement

License and collaboration agreement revenues decreased by $1.6 million, or 79%, to $435,000 for the six months ended June 30, 2021 compared to $2.1 million for the six months ended June 30, 2020. This decrease was attributable primarily to the recognition of approximately $2.0 million from Ocumension upon signing a license agreement for DEXYCU in China during the six months ended June 30, 2020, partially offset by higher billable technical support hours and material purchases by Ocumension.

Royalty Income

Royalty income decreased by $802,000, or 69%, to $361,000 for the six months ended June 30, 2021 compared to $1.2 million for the six months ended June 30, 2020. The decrease was attributable to the impact of the

33

royalty monetization agreement with SWK Holdings that grants to SWK all future royalty payments under the Amended Alimera Agreement beginning with Q4 2020 for a one-time payment of $16.5 million.  Due to the accounting treatment for this agreement (see Revenue Recognition section), we recognize a non-cash portion of deferred revenue as Alimera pays royalties to SWK beginning in the first quarter of 2021 (see Note 3). We expect lower royalty revenue related to the royalty monetization agreement in 2021 compared to 2020.

Cost of Sales, Excluding Amortization of Acquired Intangible Assets

Cost of sales, excluding amortization of acquired intangible assets, increased by $1.8 million, or 124%, to $3.3 million for the six months ended June 30, 2021 from $1.5 million for the six months ended June 30, 2020. This increase was primarily attributable costs associated with higher product sales, primarily costs of goods and royalties, due to higher DEXYCU product mix.

Research and Development

Research and development expenses increased by $3.0 million, or 36%, to $11.1 million for the six months ended June 30, 2021 from $8.1 million for the same period in the prior year. This increase was attributable primarily to (i) $2.3 million in increased clinical costs, primarily related to our EYP-1901 Phase 1 study and (ii) approximately $1.9 million of personnel related costs for incremental new hires, partially offset by a decrease of approximately $396,000 in investigator-initiated studies and other medical affairs related costs. The first quarter of 2020 also included a one-time $1.0 million payment for the licensing of vorolanib for EYP-1901.

Sales and Marketing

Sales and marketing expenses decreased by $1.9 million, or 13%, to $12.3 million for the six months ended June 30, 2021 from $14.2 million for the same period in the prior year.  This decrease was primarily attributable to (i) approximately $2.0 million in net personnel related expenses, primarily due to the reduction in DEXYCU KAMs that occurred in Q2 2020 and (ii) $1.3 million in marketing related expenses, partially offset by $1.4 million in commissions due to our commercial partner for DEXYCU.

General and Administrative

General and administrative expenses increased by $1.1 million, or 13%, to $10.3 million for the six months ended June 30, 2021 from $9.2 million for the same period in the prior year. This increase was attributable primarily to (i) $519,000 in consulting, investor relations and other spending initiatives and (ii) $318,000 in legal, audit, insurance and other professional services.

Amortization of Acquired Intangible Assets

Amortization of acquired intangible assets totaled $1.2 million for both the six months ended June 30, 2021 as well as the same period in the prior year.  This amount was attributable to the DEXYCU product intangible asset that resulted from the Icon Acquisition (see Note 5).  

Interest (Expense) Income

Interest expense totaled $2.7 million for the six months ended June 30, 2021, which included $300,000 of amortization of debt discount and $0 of non-cash payment-in-kind interest expense all related to the CRG Debt. We incurred lower interest expense due to the $13.7 million partial principal paydown in Q4-2020 on the CRG term loan.  Interest expense in the six months ended June 30, 2020 was $3.6 million which included $348,000 of amortization of debt discount and $647,000 of non-cash payment-in-kind interest expense.

Interest income from amounts invested in an institutional money market fund decreased to $6,000 for the six months ended June 30, 2021 compared to $62,000 in the prior year quarter.  At the start of the Pandemic, money market rates fell substantially beginning March 2020, current interest earned is therefore low, despite our increased cash balance.  Other income for the six months ended June 30, 2021 is $275,000 from a tax refund related to FY2020.

Gain on Extinguishment of Debt

Forgiveness by the SBA of our PPP Loan resulted in a gain on extinguishment of debt, which consisted of approximately (i) $2.0 million of principal and (ii) $24,000 of interest.

Liquidity and Capital Resources

We have had a history of operating losses and an absence of significant recurring cash inflows from revenue, and at June 30, 2021 we had a total accumulated deficit of $533.0 million. Our operations have been financed primarily from sales of our equity securities, issuance of debt and a combination of license fees, milestone payments, royalty income and other fees received from collaboration partners. In the first quarter of 2019, we commenced the U.S. launch of our first two commercial products, YUTIQ and DEXYCU. However, we have not received sufficient revenues from our product sales to fund operations and we do not expect revenues from our product sales to generate sufficient funding to sustain our operations in the near-term.

Financing Activities

Our total cash and cash equivalents were $127.6 million at June 30, 2021. During the six months ended June 30, 2021, we recorded net proceeds of $107.9 million from the issuance of shares of our common stock (“Common Stock”) in an underwritten public offering (see Note 9). We also sold shares of our common stock under our at-the-market facility during the six months ended June 30, 2021 and recorded net proceeds of approximately $499,000.

The CRG Loan is due and payable on December 31, 2023 (the “Maturity Date”). The CRG Loan bears interest at a per annum rate (subject to increase during an event of default) equal to 12.5%, of which 2.5% may be paid in-kind at the election of the Company, so long as no default or event of default under the CRG Loan Agreement has occurred and is continuing. The Company is required to make interest only payments on a quarterly basis until the Maturity Date. The Company will also be required to pay an exit fee equal to 6% of the aggregate principal amounts advanced (including any paid-in-kind amounts) under the CRG Loan Agreement. to certain exceptions, we are required to make mandatory prepayments of the CRG Loan with the proceeds of assets sales and in the event of a change of control of our Company. In addition, we may make a voluntary prepayment of the CRG Loan, in whole or in part, at any time. All mandatory and voluntary prepayments of the CRG Loan are subject to the payment of prepayment premiums as follows: (i) if prepayment occurs after December 31, 2020 and on or prior to December 31, 2021, an amount equal to 3% of the aggregate outstanding principal amount of the CRG Loan being prepaid. No prepayment premium is due on any principal prepaid after December 31, 2021.

Certain of the Company’s existing and future subsidiaries, including the Guarantors, are guaranteeing the obligations of us under the CRG Loan Agreement. Our obligations under the CRG Loan Agreement and the guarantee of such obligations are secured by a pledge of substantially all of our and the Guarantors’ assets.    

The CRG Loan Agreement contains affirmative and negative covenants customary for financings of this type, including limitations on our and our subsidiaries’ abilities, among other things, to incur additional debt, grant or permit additional liens, make investments and acquisitions, merge or consolidate with others, dispose of assets, pay dividends and distributions and enter into affiliate transactions, in each case, subject to certain exceptions. In addition, the CRG Loan Agreement contains the following financial covenants requiring us and the Guarantors to maintain:

• liquidity in an amount which shall exceed the greater of (i) $5 million and (ii) to the extent we have incurred certain permitted debt, the minimum cash balance, if any, required of the Company by the creditors of such permitted debt; and

• annual minimum product revenue from YUTIQ and DEXYCU: (i) for the twelve-month period beginning on January 1, 2021 and ending on December 31, 2021, of at least $25 million and (iii) for the twelve-month period beginning on January 1, 2022 and ending on December 31, 2022, of at least $90 million.

On May 3, 2021, we entered into a waiver to the CRG Loan Agreement (the “Waiver”), pursuant to which CRG reduced the financial covenant associated with our revenue derived from sales of YUTIQ and DEXYCU for the twelve-month period ended December 31, 2021 from $45 million to $25 million. On October 8, 2020, we entered into a Waiver to the CRG Loan Agreement (the “Waiver”) pursuant to which CRG waived the financial covenant associated with our revenue derived from sales of YUTIQ and DEXYCU for the twelve-month period ended December 31, 2020 and reduced the revenue covenant for the twelve-month period ending December 31, 2021 from $80 million to $45 million. On November 19, 2019, we entered into a Waiver to the CRG Loan Agreement (the “Waiver”) pursuant to which CRG waived the financial covenant associated with our revenue derived from sales of YUTIQ and DEXYCU for the twelve-month period ended December 31, 2019. If we do not maintain compliance

35

with all of the continuing covenants and other terms and conditions of the CRG Loan or secure a waiver for any non-compliance, then the Lenders may choose to declare an event of default and require that we immediately repay all amounts outstanding, plus penalties and interest, including an exit fee and any prepayment fees, and foreclose on the collateral granted to them to secure such indebtedness. Such repayment would have a material adverse effect on our business and financial condition.

On December 17, 2020, we paid $15.0 million against the CRG Loan obligations in connection with the consummation of the RPA agreement (see Note 3). In addition to repayment of the $13.8 million principal portion of the CRG Loan, we paid (i) the $828,000 Exit Fee, and (ii) accrued and unpaid interest of $378,000 through that date. CRG waived the financial covenant in the CRG Loan associated with the payment of prepayment premiums if prepayment occurred after December 31, 2019 and on or prior to December 31, 2020. As of June 30, 2021, our outstanding balance, including principal and the exit fee, under the CRG Loan was approximately $40.5 million, and consisted of approximately $38.5 million of carrying value (see Note 12), and $2.0 million of the remaining balance of unamortized debt discount related to the CRG Loan.

Future Funding Requirements

At June 30, 2021, we had cash and cash equivalents of $127.6 million.  We expect that our cash and cash equivalents combined with anticipated net cash inflows from product sales will fund our operating plan through December 31, 2022, under current expectations regarding (i) the timing and outcomes of our Phase 1 clinical trial for EYP-1901 for the treatment of wet AMD, and (ii) initiation of our Phase 2 clinical trials for EYP-1901 for the treatment of wet AMD. Due to the difficulty and uncertainty associated with the design and implementation of clinical trials, we will continue to assess our cash and cash equivalents and future funding requirements.  However, there is no assurance that additional funding will be achieved and that we will succeed in our future operations.

Actual cash requirements could differ from management’s projections due to many factors, including cash generation from sales of YUTIQ and DEXYCU, additional investments in research and development programs, clinical trial expenses for EYP-1901, competing technological and market developments and the costs of any strategic acquisitions and/or development of complementary business opportunities. In addition, the Pandemic has had, and will likely continue to have, a material and adverse impact on our business, including as a result of preventive and precautionary measures that we, other businesses, and governments are taking. Due to these impacts and measures, we have experienced and will likely continue to experience significant and unpredictable reductions in the demand for our commercial products as customers have shut down their facilities and non-essential surgical procedures have been postponed in an effort to promote social distancing and to redirect medical resources and priorities towards the treatment of COVID-19.

The amount of additional capital we will require will be influenced by many factors, including, but not limited to:

• the potential for EYP-1901, as a twice-yearly sustained delivery intravitreal anti-VEGF treatment targeting wet age-related macular degeneration (“wet AMD”), with potential in diabetic retinopathy (“DR”) and retinal vein occlusion (“RVO”);

• our expectations regarding the timing and clinical development of our product candidates, including EYP-1901 and YUTIQ 50;

• the success of our U.S. direct commercialization of YUTIQ for the treatment of chronic non-infectious uveitis affecting the posterior segment of the eye including, among other things, patient and physician acceptance of YUTIQ and our ability to obtain adequate coverage and reimbursement for YUTIQ;

• the success of our U.S. direct commercialization of DEXYCU for the treatment of postoperative ocular inflammation including, among other things, patient and physician acceptance of DEXYCU and our ability to obtain adequate coverage and reimbursement for DEXYCU;

• the cost of commercialization activities for YUTIQ and DEXYCU, including product manufacturing, marketing, sales and distribution;

• the scheduled March 31, 2022 expiration of pass-through coverage under which DEXYCU is reimbursed for Medicare Part B patients, and our expectations regarding any potential extensions thereof;

• whether and to what extent we internally fund, whether and when we initiate, and how we conduct other product development programs;

• payments we receive under any new collaboration agreements;

36

• whether and when we are able to enter into strategic arrangements for our products or product candidates and the nature of those arrangements;

• the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing any patent claims;

• changes in our operating plan, resulting in increases or decreases in our need for capital;

• our views on the availability, timing and desirability of raising capital; and

• the extent to which our business could be adversely impacted by the effects of the Pandemic or by other pandemics, epidemics or outbreaks.

We do not know if additional capital will be available when needed or on terms favorable to us or our stockholders. Collaboration, licensing or other agreements may not be available on favorable terms, or at all. We do not know the extent to which we will receive funds from the commercialization of YUTIQ or DEXYCU. If we seek to sell our equity securities, we do not know whether and to what extent we will be able to do so, or on what terms. If available, additional equity financing may be dilutive to stockholders, debt financing may involve restrictive covenants or other unfavorable terms and dilute our existing stockholders’ equity, and funding through collaboration, licensing or other commercial agreements may be on unfavorable terms, including requiring us to relinquish rights to certain of our technologies or products. If adequate financing is not available if and when needed, we may delay, reduce the scope of, or eliminate research or development programs, independent commercialization of YUTIQ and DEXYCU, or other new products, if any, postpone or cancel the pursuit of product candidates, or otherwise significantly curtail our operations to reduce our cash requirements and extend our capital.

Our consolidated statements of historical cash flows are summarized as follows (in thousands):

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and our principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2021. The term “disclosure controls and procedures”, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, as appropriate, to allow timely decisions regarding required disclosure, particularly during the period in which this Quarterly Report on Form 10-Q was being prepared. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their desired objectives, and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of June 30, 2021, our principal executive officer and our principal financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

During the quarter ended June 30, 2021, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

38

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Operations

1.Operations

         The accompanying condensed consolidated financial statements of EyePoint Pharmaceuticals, Inc., a Delaware corporation (together with its subsidiaries, the “Company”), as of June 30, 2021 and for the three and six months ended June 30, 2021 and 2020 are unaudited. Certain information in the footnote disclosures of these financial statements has been condensed or omitted in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). These financial statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. In the opinion of management, these statements have been prepared on the same basis as the audited consolidated financial statements as of and for the year ended December 31, 2020, and include all adjustments, consisting only of normal recurring adjustments, that are necessary for the fair presentation of the Company’s financial position, results of operations, comprehensive loss and cash flows for the periods indicated. The preparation of financial statements in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) requires management to make assumptions and estimates that affect, among other things, (i) reported amounts of assets and liabilities; (ii) disclosure of contingent assets and liabilities at the date of the consolidated financial statements; and (iii) reported amounts of revenues and expenses during the reporting period. The results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the entire fiscal year or any future period.

         The Company is a pharmaceutical company committed to developing and commercializing innovative therapeutics to help improve the lives of patients with serious eye disorders. The Company’s pipeline leverages its proprietary Durasert^® technology for extended intraocular drug delivery including EYP-1901, a potential twice-yearly sustained delivery intravitreal anti-VEGF treatment initially targeting wet age-related macular degeneration (“wet AMD”), the leading cause of vision loss among people 50 years of age and older in the United States. The Company’s product candidate pipeline also includes YUTIQ^® 50, a potential twice-yearly treatment for non-infectious uveitis affecting the posterior segment of the eye, one of the leading causes of blindness. The Company also has two commercial products: YUTIQ^®, a once every three-year treatment for chronic non-infectious uveitis affecting the posterior segment of the eye, and DEXYCU^®, a single dose treatment for postoperative inflammation following ocular surgery.

Local drug delivery for treating ocular diseases is a significant challenge due to the effectiveness of the blood-eye barrier. This barrier makes it difficult for systemically-administered drugs to reach the eye in sufficient quantities to have a beneficial effect without causing unacceptable adverse side effects to other organs. The Company’s validated Durasert technology, which has already been included in four products approved for marketing by the U.S. Food and Drug Administration (“FDA”), is designed to provide consistent, sustained delivery of small molecule drugs over a period of months to years through a single intravitreal injection.

The Company’s lead product candidate, EYP-1901, combines a bioerodible formulation of its proprietary Durasert sustained-release technology with vorolanib, a tyrosine kinase inhibitor (“TKI”). The Company is currently evaluating EYP-1901 in a Phase 1 clinical trial as a potential twice-yearly sustained delivery intravitreal treatment for wet AMD. Current approved treatments for wet AMD require monthly or bi-monthly eye injections in a physician’s office, which can cause inconvenience and discomfort and often lead to reduced compliance and poor outcomes. On May 25, 2021, the Company announced the completion of the enrollment of the Phase 1 DAVIO clinical trial of EYP-1901 and expects initial data from trial in the fourth quarter of 2021.

The Company is also developing YUTIQ 50 as a potential twice-yearly intravitreal treatment for chronic non-infectious uveitis affecting the posterior segment of the eye. The Company has consulted with the FDA and identified a clinical pathway for a supplemental new drug application (“sNDA”) filing that the Company expects will involve a clinical trial of a small population. The Company expects to initiate the Phase 3 clinical trial for YUTIQ 50 by the end of this year.

The Company also has two commercial products, YUTIQ^® and DEXYCU^®, that are being sold directly in the U.S.  

YUTIQ^® (fluocinolone acetonide intravitreal implant) 0.18 mg for intravitreal injection, is a non-erodible intravitreal implant containing fluocinolone acetonide (“FA”) lasting for up to 36 months and is indicated for the treatment of chronic non-infectious uveitis affecting the posterior segment of the eye. This disease affects between 60,000 to 100,000 people each year in the U.S. causes approximately 30,000 new cases of blindness every year and

is the third leading cause of blindness. YUTIQ utilizes the Company’s proprietary Durasert^® sustained-release drug delivery technology platform.

DEXYCU^® (dexamethasone intraocular suspension) 9%, for intraocular administration, is indicated for the treatment of post-operative ocular inflammation, with the Company’s primary focus on its use immediately following cataract surgery as a single dose treatment. DEXYCU utilizes the Company’s proprietary Verisome^® drug-delivery technology.

The Company is also seeking to enhance its long-term growth potential by expanding EYP-1901 beyond wet AMD into diabetic retinopathy (“DR”) and retinal vein occlusion (“RVO”), both large and growing ocular disease areas. The Company also expects to potentially identify and advance additional product pipeline candidates through clinical and regulatory development. This may be accomplished through internal discovery efforts, potential research collaborations and/or in-licensing arrangements with partner molecules and potential acquisitions of additional ophthalmic products, product candidates or technologies that complement the Company’s current product portfolio.

Effects of the COVID-19 Coronavirus Pandemic

The ongoing COVID-19 coronavirus pandemic (the “Pandemic”) has had a material and adverse impact on the Company’s business, including as a result of measures that the Company, other businesses, and governments have taken and will possibly continue to take. This includes a significant impact on cash flows from expected revenues due to the closure of ambulatory surgery centers for DEXYCU and a significant reduction in physician office visits impacting YUTIQ in 2020. The ongoing Pandemic continued to have an adverse impact on the Company’s revenues, financial condition and cash flows in the first quarter and second quarter of 2021. Further, the future progression of the Pandemic and its effects on the Company’s business and operations are uncertain at this time. Depending on the future developments that are uncertain and difficult to predict, including new information that may emerge concerning the Pandemic, the Company’s revenues, financial condition and cash flows may be adversely affected in the future as well. The Company is continuously monitoring the Pandemic and its potential effect on the Company’s financial position, results of operations and cash flows. This uncertainty could have an impact in future periods on certain estimates used in the preparation of the Company’s periodic financial results, including reserves for variable consideration related to product sales, realizability of certain receivables, assessment for excess or obsolete inventory, and impairment of long-lived assets. Uncertainty around the extent and duration of the Pandemic, and any future related financial impact cannot be reasonably estimated at this time.

Liquidity

The Company had cash and cash equivalents of $127.6 million at June 30, 2021. The Company has a history of operating losses and has not had significant recurring cash inflows from revenue. The Company’s operations have been financed primarily from sales of its equity securities, issuance of debt and a combination of license fees, milestone payments, royalty income and other fees received from its collaboration partners. In the first quarter of 2019, the Company commenced the U.S. launch of its first two commercial products, YUTIQ and DEXYCU. However, the Company has not received sufficient revenues from its product sales to fund operations and the Company does not expect revenues from its product sales to generate sufficient funding to sustain its operations in the near-term. The Company expects to continue fulfilling its funding needs through cash inflows from revenue of YUTIQ and DEXYCU product sales, licensing and research collaboration transactions, additional equity capital raises and other arrangements. The Company believes that its cash and cash equivalents of $127.6 million at June 30, 2021, coupled with expected cash inflows from its product sales will enable the Company to fund its current and planned operations for at least the next twelve months from the date these consolidated financial statements were issued. Actual cash requirements could differ from management’s projections due to many factors, including the continued effect of the Pandemic on the Company’s business and the medical community, the timing and results of the Company’s clinical trials for EYP-1901, additional investments in research and development programs, the success of commercialization for YUTIQ and DEXYCU, the actual costs of these commercialization efforts, competing technological and market developments and the costs of any strategic acquisitions and/or development of complementary business opportunities.

Recently Adopted and Recently Issued Accounting Pronouncements

New accounting pronouncements are issued periodically by the Financial Accounting Standards Board (“FASB”) and are adopted by the Company as of the specified effective dates. Unless otherwise disclosed below, the

Company believes that recently issued and adopted pronouncements will not have a material impact on the Company’s financial position, results of operations and cash flows or do not apply to the Company’s operations.   

In May 2021, the FASB issued ASU No. 2021-04, Earnings Per Share (Topic 260), Debt— Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2021-04”): Issuer’s  Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. The amendments are designed to clarify an issuer’s accounting for certain modifications or exchanges of freestanding equity-classified written call options that remain equity-classified after modification or exchange. The ASU provides guidance on how an issuer would measure and recognize the effects of these transactions. The standard provides a principles-based framework to determine whether an issuer should recognize the modification or exchange as an adjustment to equity or an expense. ASU 2021-04 is effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. Early adoption is permitted, including adoption in interim or annual periods for which financial statements have not yet been issued. ASU 2021-04 will be effective for the Company in the first quarter of its fiscal year ending December 31, 2022. The Company is currently evaluating the impact the adoption of this update will have on its consolidated financial statements.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Revenue Recognition

Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, Revenue from Contracts with Customers (“ASC 606”), the Company 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. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract, determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

Product sales, net — The Company sells YUTIQ and DEXYCU to a limited number of specialty distributors and specialty pharmacies (collectively the “Distributors”) in the U.S., with whom the Company has entered into formal agreements, for delivery to physician practices for YUTIQ and to hospital outpatient departments and ambulatory surgical centers for DEXYCU. The Company recognizes revenue on sales of its products when Distributors obtain control of the products, which occurs at a point in time, typically upon delivery. In addition to agreements with Distributors, the Company also enters into arrangements with healthcare providers, ambulatory surgical centers, and payors that provide for government mandated and/or privately negotiated rebates, chargebacks, and discounts with respect to the purchase of the Company’s products from Distributors.

Reserves for variable consideration — Product sales are recorded at the wholesale acquisition costs, net of applicable reserves for variable consideration. Components of variable consideration include trade discounts and allowances, provider chargebacks and discounts, payor rebates, product returns, and other allowances that are offered within contracts between the Company and its Distributors, payors, and other contracted purchasers relating to the Company’s product sales. These reserves, as detailed below, are based on the amounts earned, or to be claimed on the related sales, and are classified either as reductions of product revenue and accounts receivable or a current liability, depending on how the amount is to be settled. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the respective underlying contracts. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results in the future vary from the estimates, the Company adjusts these estimates, which would affect product revenue and earnings in the period such variances become known.

Distribution fees — The Company compensates its Distributors for services explicitly stated in the Company’s contracts and are recorded as a reduction of revenue in the period the related product sale is recognized.

Provider chargebacks and discounts — Chargebacks are discounts that represent the estimated obligations resulting from contractual commitments to sell products at prices lower than the list prices charged to the Company’s Distributors. These Distributors charge the Company for the difference between what they pay for the product and the Company’s contracted selling price. These reserves are established in the same period that the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability. Reserves for chargebacks consist of amounts that the Company expects to pay for units that remain in the distribution channel inventories at each reporting period-end that the Company expects will be sold under a contracted selling price, and chargebacks that Distributors have claimed, but for which the Company has not yet settled.

Government rebates — The Company is 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 condensed consolidated balance sheets. The Company’s 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.

Payor rebates — The Company contracts with certain private payor organizations, primarily insurance companies, for the payment of rebates with respect to utilization of its products. The Company estimates these rebates and records such estimates in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability.

Co-Payment assistance — The Company offers co-payment assistance to commercially insured patients meeting certain eligibility requirements. The calculation of the accrual for co-pay assistance is based on an estimate of claims and the cost per claim that the Company expects to receive associated with product that has been recognized as revenue.

Product returns — The Company generally offers a limited right of return based on its returned goods policy, which includes damaged product and remaining shelf life. The Company estimates the amount of its product sales that may be returned and records this estimate as a reduction of revenue in the period the related product revenue is recognized, as well as reductions to trade receivables, net on the condensed consolidated balance sheets.

License and collaboration agreement revenue — The Company analyzes each element of its license and collaboration arrangements to determine the appropriate revenue recognition. The terms of the license agreement may include payment to the Company of non-refundable up-front license fees, milestone payments if specified objectives are achieved, and/or royalties on product sales. The Company recognizes revenue from upfront payments at a point in time, typically upon fulfilling the delivery of the associated intellectual property to the customer.

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations.

The Company recognizes sales-based milestone payments as revenue upon the achievement of the cumulative sales amount specified in the contract in accordance with ASC 606-10-55-65. For those milestone payments which are contingent on the occurrence of particular future events, the Company determines that these need to be considered for inclusion in the calculation of total consideration from the contract as a component of variable consideration using the most-likely amount method. As such, the Company assesses each milestone to determine the probability and substance behind achieving each milestone. Given the inherent uncertainty associated with these future events, the Company will not recognize revenue from such milestones until there is a high probability of occurrence, which typically occurs near or upon achievement of the event.

When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component.

Applying the practical expedient in paragraph 606-10-32-18, the Company does not assess whether a significant financing component exists if the period between when the Company performs its obligations under the contract and when the customer pays is one year or less. None of the Company’s contracts contained a significant financing component as of June 30, 2021.

Royalties — The Company recognizes revenue from license arrangements with its commercial partners’ net sales of products. Such revenues are included as royalty income. In accordance with ASC 606-10-55-65, royalties are recognized when the subsequent sale of the commercial partner’s products occurs. The Company’s commercial partners are obligated to report their net product sales and the resulting royalty due to the Company typically within 60 days from the end of each quarter. Based on historical product sales, royalty receipts and other relevant information, the Company recognizes royalty income each quarter and subsequently determines a true-up when it receives royalty reports and payment from its commercial partners. Historically, these true-up adjustments have been immaterial.

Sale of Future Royalties — The Company has sold its rights to receive certain royalties on product sales. In the circumstance where the Company has sold its rights to future royalties under a royalty purchase agreement and also maintains limited continuing involvement in the arrangement (but not significant continuing involvement in the generation of the cash flows that are due to the purchaser), the Company defers recognition of the proceeds it receives for the sale of royalty streams and recognizes such unearned revenue as revenue under the units-of-revenue method over the life of the underlying license agreement. Under the units-of-revenue method, amortization for a reporting period is calculated by computing a ratio of the proceeds received from the purchaser to the total payments expected to be made to the purchaser over the term of the agreement, and then applying that ratio to the period’s cash payment.

Estimating the total payments expected to be received by the purchaser over the term of such arrangements requires management to use subjective estimates and assumptions. Changes to the Company’s estimate of the payments expected to be made to the purchaser over the term of such arrangements could have a material effect on the amount of revenues recognized in any particular period.

Research Collaborations — The Company recognizes revenue over the term of the statements of work under any funded research collaborations. Revenue recognition for consideration, if any, related to a license option right is assessed based on the terms of any such future license agreement or is otherwise recognized at the completion of the research collaborations.

Please refer to Note 3 for further details on the license and collaboration agreements into which the Company has entered and corresponding amounts of revenue recognized during the current and prior year periods.

Cost of sales, excluding amortization of acquired intangible assets — Cost of sales, excluding amortization of acquired intangible assets, consist of costs associated with the manufacture of YUTIQ and DEXYCU, certain period costs, product shipping and, as applicable, royalty expense. The inventory costs for YUTIQ include purchases of various components, the active pharmaceutical ingredient (“API”) and internal labor and overhead for the product manufactured in the Company’s Watertown, MA facility. The inventory costs for DEXYCU include purchased components, the API and third-party manufacturing and assembly.

For the three months ended June 30, 2021 and 2020, the Company accrued DEXYCU product revenue-based royalty expense of $648,000 and $99,000, respectively, as a component of cost of sales. For the six months ended June 30, 2021 and 2020, the Company accrued DEXYCU product revenue-based royalty expense of $1.1 million and $616,000, respectively, as a component of cost of sales, of which $0 and $400,000, respectively, were related to the earn-out payment equal to 20% of the $2 million upfront license fee received from Ocumension in February 2020 (See Note 3), as the payment of the partnering income in connection with the Company’s acquisition of Icon Bioscience, Inc. in March 2018 (the “Icon Acquisition”).

License and Collaboration Agreements and Royalty Income

Alimera

Pursuant to a licensing and development agreement, as amended (the “Amended Alimera Agreement”), Alimera Sciences, Inc. (“Alimera”) has a worldwide exclusive license to develop, make, market and sell ILUVIEN in return for royalties based on sales and patent fee reimbursements. Royalties income was $0 and $381,000 for the three months ended June 30, 2021 and 2020, respectively, and $0 and $1.2 million for the six months ended June 30, 2021 and 2020, respectively. Total revenue was $2,000 and $386,000 for the three months ended June 30, 2021 and 2020, respectively, and $15,000 and $1.2 million for the six months ended June 30, 2021 and 2020, respectively.

SWK Royalty Purchase Agreement

On December 17, 2020, the Company entered into a royalty purchase agreement (the “RPA”) with SWK Funding LLC (“SWK”). Under the RPA, the Company sold its right to receive royalty payments on future sales of products subject to the Amended Alimera Agreement for an upfront cash payment of $16.5 million. Except for the rights to the royalties, the Company retains all rights and obligations under the Amended Alimera Agreement, pursuant to which, Alimera owns worldwide rights to the Company’s Durasert technology in ILUVIEN for diabetic macular edema (“DME”) and rights for ILUVIEN (currently marketed by the Company as YUTIQ in the U.S.) for non-infectious posterior uveitis in Europe, the Middle East, and Africa (“EMEA”). Alimera has the sole rights to utilize the intellectual property developed under the Amended Alimera Agreement. There has been no intellectual property developed jointly by Alimera and the Company as part of the Amended Alimera Agreement. The Company cannot utilize the intellectual property for the indication licensed to Alimera in order to manufacture and sell ILUVIEN.

The Company’s ongoing efforts under the Amended Alimera Agreement will consist of continuing to maintain and enforce its patents as well as providing safety data and regulatory support as necessary. None of these obligations require significant efforts on the part of the Company with respect to the generation of sales in the market. The Company will only be required to expend more extensive efforts if litigation were to arise that requires the Company to protect its patents rights pursuant to the terms of the Amended Alimera Agreement. Historically, such a defense has not been required. Similarly, regulatory support and safety data is only provided on an ad-hoc basis depending on the regulatory requests, which has been minimal historically. It remains Alimera’s sole responsibility to manufacture, actively market and promote the products under the Amended Alimera Agreement to generate the sales, which ultimately generate the royalties to be paid to SWK.

The Company classified the proceeds received from SWK as deferred revenue, to be recognized as revenue under the units-of-revenue method over the life of the RPA because of the Company’s limited continuing involvement in the Amended Alimera Agreement. SWK has no recourse and the Company assumes no credit risk in event that Alimera fails to make a royalty payment. The Company must only forward all material correspondence from Alimera to SWK, including royalty reports, notices and any other correspondence with respect to royalties to SWK. SWK has the right to audit and inspect the books and records pertaining to net sales and royalties under the Amended Alimera Agreement. Neither the Company nor SWK has the unilateral ability to cancel the transaction. There is no cap or limitation on the royalties to be received by SWK in the future and its return will reflect all royalties paid by Alimera. Because the transaction was structured as a non-cancellable sale, the Company does not have significant continuing involvement in the generation of the cash flows due to SWK and there is no limitation on the rates of return to SWK, the Company recorded the total proceeds of $16.5 million as deferred revenue under royalty sale agreement. The deferred revenue is being recognized as revenue over the life of the RPA under the "units-of-revenue" method. Under this method, amortization for a reporting period is calculated by computing a ratio of the proceeds received from SWK to the payments expected to be made by Alimera to SWK over the term of the Amended Alimera Agreement, and then applying that ratio to the period’s cash payment.

The Company recognized $181,000 and $361,000 of royalty revenue related to the RPA for the three and six months ended June 30, 2021, in connection with the royalty payment of $583,000 and $1.2 million for the three and six months ended June 30, 2021 from Alimera to SWK, pursuant to the Amended Alimera Agreement. No revenue was recognized related to the RPA for the three and six months ended June 30, 2020. As of June 30, 2021, the Company had $1.0 million and $15.1 million as current and non-current deferred revenue recognized under royalty sale agreement, respectively. As of December 31, 2020, the Company classified $885,000 and $15.6 million as current and non-current deferred revenue recognized under royalty sale agreement, respectively.

Ocumension Therapeutics

In November 2018, the Company entered into an exclusive license agreement with Ocumension Therapeutics (“Ocumension”) for the development and commercialization of its three-year micro insert using the Durasert technology for the treatment of chronic non-infectious uveitis affecting the posterior segment of the eye (YUTIQ in the U.S.) in Mainland China, Hong Kong, Macau and Taiwan. The Company received a one-time upfront payment of $1.75 million from Ocumension and is eligible to receive up to (i) $7.25 million upon the achievement by Ocumension of certain prescribed development and regulatory milestones, and (ii) $3.0 million commercial sales-based milestones. In addition, the Company is entitled to receive mid-single digit sales-based royalties. Ocumension has also received a special approval by the Hainan Province People's Government to market this product for chronic, non-infectious posterior segment uveitis in the Hainan Bo Ao Lecheng International Medical Tourism Pilot Zone (“Hainan Pilot Zone”). In March 2019, the Company entered into a Memorandum of Understanding (“2019 MOU”), pursuant to which, the Company will supply product for the clinical trials and Hainan Pilot Zone use. Paralleling to Ocumension’s normal registration process of the product with the Chinese Regulatory Authorities, the 2019 MOU modified the Company’s entitlement to the development and regulatory milestones of up to $7.25 million under the license agreement to product supply milestones or development milestones, whichever comes first, totaling up to $7.25 million. In August 2019, the Company began shipping this product to Ocumension.

The Company was required to provide a fixed number of hours of technical assistance support to Ocumension at no cost, which support has been completed and no future performance obligation exists. Ocumension is responsible for all development, regulatory and commercial costs, including any additional technical assistance requested. Ocumension has a first right of negotiation for an additional exclusive license to the Company’s shorter-duration line extension candidate for this indication.

In August 2019, the Company received a $1.0 million development milestone payment from Ocumension triggered by the approval of its Investigational New Drug (“IND”) in China for this program. The IND allows the importation of finished product into China for use in a clinical trial to support regulatory filing.

In January 2020, the Company entered into an exclusive license agreement with Ocumension for the development and commercialization in Mainland China, Hong Kong, Macau and Taiwan of DEXYCU for the treatment of post-operative inflammation following ocular surgery. Pursuant to the terms of the license agreement, the Company received upfront payments of $2.0 million from Ocumension in February 2020 and will be eligible to receive up to (i) $6.0 million upon the achievement by Ocumension of certain prescribed development and regulatory milestones, and (ii) $6.0 million commercial sales-based milestones. In addition, the Company is entitled to receive mid-single digit sales-based royalties. In exchange, Ocumension will receive exclusive rights to develop and commercialize DEXYCU in Mainland China, Hong Kong, Macau and Taiwan, at its own cost and expense with the Company supplying product for clinical trials and commercial sale. In addition, Ocumension will receive a fixed number of hours of technical assistance support from the Company at no cost.

In August 2020, the Company entered into a Memorandum of Understanding (“2020 MOU”), pursuant to which, the Company received a one-time non-refundable payment of $9.5 million (the “Accelerated Milestone Payment”) from Ocumension as a full and final payment of the combined remaining development, regulatory and sales milestone payments under the Company’s license agreements with Ocumension for the treatment of chronic non-infectious uveitis affecting the posterior segment of the eye and for the treatment of post-operative inflammation following ocular surgery, respectively. Upon payment of the Accelerated Milestone Payment, the remaining $11.75 million in combined remaining development and sales milestone payments under the Company’s original license agreement with Ocumension upon the achievement by Ocumension of (i) remaining development and regulatory milestones of $6.25 million and commercial sales-based milestones of $3.0 million for the development and commercialization of its three-year micro insert using the Durasert technology for the treatment of chronic non-infectious uveitis affecting the posterior segment of the eye; and (ii) $6.0 million upon the achievement by Ocumension of certain prescribed development and regulatory milestones, and $6.0 million commercial sales-based milestones for the development and commercialization in Mainland China, Hong Kong, Macau and Taiwan of DEXYCU for the treatment of post-operative inflammation following ocular surgery, totaling up to $21.25 million, were permanently extinguished and will no longer be due and owed to the Company. In exchange, Ocumension also received exclusive rights to develop and commercialize YUTIQ and DEXYCU products under its own brand names in South Korea and other jurisdictions across Southeast Asia in Brunei, Burma (Myanmar), Cambodia, Timor-Leste, Indonesia, Laos, Malaysia, the Philippines, Singapore, Thailand and Vietnam, at its own cost and expense with the Company supplying product for clinical trials and commercial sale. The Company continues to be entitled to royalties on future product sales by Ocumension. In April 2021, Ocumension filed a New Drug Application

(“NDA”) for YUTIQ under Ocumension’s distinct name to Chinese regulatory authorities and it is under review. Ocumension has been granted approval to have its NDA submission reviewed based on the U.S. NDA data and the real world data Ocumension has collected from marketing the product in Hainan Pilot Zone.

Other than a fixed number of hours of technical assistance support to be provided at no cost by the Company, Ocumension is responsible for all development, regulatory and commercial costs, including any additional technical assistance requested. All technical assistance was provided during 2020. The Chief Executive Officer of Ocumension became a director of the Company starting December 31, 2020, pursuant to a Share Purchase Agreement pursuant to which the Company sold to Ocumension 3,010,722 shares of common stock, at which time, Ocumension became a related party of the Company.

During the three months ended June 30, 2021 and 2020, the Company recognized $91,000 and $0, respectively, related to additional technical assistance. During the six months ended June 30, 2021 and 2020, the Company recognized $360,000, related to additional technical assistance, and approximately $2.0 million of license and collaboration revenue, respectively.   

The Company recognized no sales-based royalty expense during the three months ended June 30, 2021 and 2020. The Company recognized $0 and $400,000 of accrued sales-based royalty expense during the six months ended June 30, 2021 and 2020, respectively, related to the earn-out payment equal to 20% of the $2.0 million upfront license fee received from Ocumension in February 2020, as the payment of the partnering income in connection with the Icon Acquisition in March 2018.   

Research Collaborations

The Company from time to time enters into funded agreements to evaluate the potential use of its technology systems for sustained release of third-party partner drug candidates. Consideration received is generally recognized as revenue over the term of the research collaborations. Revenue recognition for consideration, if any, related to a license option right is assessed based on the terms of any such future license agreement or is otherwise recognized at the completion of the research collaborations. No revenues recognized under research collaborations for each of the three months ended June 30, 2021 and 2020, and $60,000 and $15,000 for the six months ended June 30, 2021 and 2020, respectively. At June 30, 2021 and December 31, 2020, $0 and $60,000 deferred revenue was recorded for the research collaborations, respectively.

Leases

7. Leases

On May 17, 2018, the Company amended the lease for its headquarters in Watertown, Massachusetts. The original five-year lease for approximately 13,650 square feet of combined office and laboratory space was set to expire in April 2019. Under the amendment, the Company leased an additional 6,590 square feet of rentable area of the building, with a commencement date of September 10, 2018. The amendment extended the term of the lease for the combined space through May 31, 2025. On April 5, 2021, the Company further amended the lease to include an additional 1,409 square feet of rentable area of the building through May 31, 2025, with a commencement date of July 1, 2021. The landlord agreed to provide the Company a construction allowance of up to $670,750 to be applied toward the aggregate work completed on the total space. The Company has an option to further extend the term of the lease for one additional five-year period. Per the terms of the lease agreement, the Company does not have a residual value guarantee. The Company previously provided a cash-collateralized $150,000 irrevocable standby letter of credit as security for the Company’s obligations under the lease, which was extended through the period that is four months beyond the expiration date of the amended lease. The Company will also be required to pay its proportionate share of certain operating costs and property taxes applicable to the leased premises in excess of new base year amounts.

In July 2017, the Company leased approximately 3,000 square feet of office space in Basking Ridge, New Jersey under a lease term extending through June 2022, with two five-year renewal options at 95% of the then-prevailing market rates. In addition to base rent, the Company is obligated to pay its proportionate share of building operating expenses and real estate taxes in excess of base year amounts. In June 2018, the Company subleased an additional 1,381 square feet of adjoining space from Caladrius Biosciences, Inc. (“Caladrius”) through May 2022. The Chief Executive Officer of Caladrius was a director of the Company through June 2020. Per the terms of the lease and sublease agreements, the Company does not have any residual value guarantees.

The Company identified and assessed the following significant assumptions in recognizing its right-of-use (“ROU”) assets and corresponding lease liabilities:

• As the Company’s leases do not provide an implicit rate, the Company estimated the incremental borrowing rate in calculating the present value of the lease payments. The Company utilized the borrowing rate under its existing 5-year term loan facility (see Note 8) as the discount rate.

• Since the Company elected to account for each lease component and its associated non-lease components as a single combined component, all contract consideration was allocated to the combined lease component.

• The expected lease terms include noncancelable lease periods. Renewal option periods have not been included in the determination of the lease terms as they are not deemed reasonably certain of exercise.

• Variable lease payments, such as common area maintenance, real estate taxes and property insurance are not included in the determination of the lease’s ROU asset or lease liability.

As of June 30, 2021, the weighted average remaining term of the Company’s operating leases was 3.8 years and the lease liabilities arising from obtaining ROU assets reflect a weighted average discount rate of 12.5%.

Supplemental balance sheet information related to operating leases as of June 30, 2021 and December 31, 2020 are as follows (in thousands):

	June 30,		December 31,
	2021		2020

Operating lease liabilities – noncurrent portion		2,013		2,330
Total operating lease liabilities	$	2,626	$	2,898

Operating lease expense recognized related to ROU assets was $213,000, excluding $9,000 of variable lease costs, for each of the three months ended June 30, 2021 and 2020, and $427,000 related to ROU assets, excluding $18,000 of variable lease costs, during each of the six months ended June 30, 2021 and 2020, and were included in general and administrative expense in the Company’s statement of comprehensive loss. Cash paid for amounts included in the measurement of operating lease liabilities was $221,000 and $215,000 for the three months ended June 30, 2021 and 2020, respectively, and $442,000 and $430,000 for the six months ended June 30, 2021 and 2020, respectively.

The Company is a party to two finance leases for laboratory equipment. The equipment leases expire in December 2021 and December 2022, respectively.

Supplemental balance sheet information related to the finance lease as of June 30, 2021 and December 31, 2020 are as follows (in thousands):

The components of finance lease expense recognized during the three and six months ended June 30, 2021 related to ROU assets was $30,000 and $62,000 and interest on lease liabilities was $4,000 and $10,000. Cash paid for amounts included in the measurement of finance lease liabilities were operating cash flows of $4,000 and $10,000 during the three and six months ended June 30, 2021, respectively, and financing cash flows of $29,000 and $58,000 during the three and six months ended June 30, 2021, respectively.  The components of finance lease expense recognized during the three and six months ended June 30, 2020 related to ROU assets were $13,000 and $27,000, respectively. Interest on lease liabilities were $2,000 and $5,000, respectively, during the three and six months ended June 30, 2020. Cash paid for amounts included in the measurement of finance lease liabilities were operating cash flows of $2,000 and $4,000 during the three and six months ended June 30, 2020, and financing cash flows of $12,000 and $20,000 during the three and six months ended June 30, 2020.

As of June 30, 2021, the weighted average remaining term of the Company’s finance lease was 1.3 years and the lease liabilities arising from obtaining ROU assets reflect a weighted average discount rate of 12.5%.

On April 8, 2020, the Company applied to Silicon Valley Bank (the “SVB”) for a Paycheck Protection Program Loan (the “PPP Loan”) of $2.0 million that is administered by the U.S. Small Business Administration (the “SBA”), under the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”). On April 22, 2020, the PPP Loan was approved and the Company received the PPP Loan proceeds.

or full forgiveness and principal and interest payments can be deferred as described below, if the PPP Loan proceeds are used for covered payroll costs, rent and utility costs and the maintenance of employee and compensation levels.

The Paycheck Protection Program Flexibility Act of 2020 (the “PPP Flexibility Act”), enacted on June 5, 2020, amended the Paycheck Protection Program, among others, as follows: (i) extended the covered period from 8 weeks to the earlier of 24 weeks from the date the PPP Loan is originated and December 31, 2020, during which PPP funds needed to be expended in order to be forgiven. A borrower may submit a loan forgiveness application any time on or before the maturity date of the loan – including before the end of the covered period – if the borrower has used all of the loan proceeds for which the borrower is requesting forgiveness; (ii) at least 60% of PPP funds must be spent on payroll costs, with the remaining 40% available to spend on other eligible expenses; (iii) payments are deferred until the date on which the amount of forgiveness determined is remitted to the lender. If a borrower fails to seek forgiveness within 10 months after the last day of its covered period, then payments will begin on the date that is 10 months after the last day of the covered period. In addition, the PPP Flexibility Act modified the CARES Act by increasing the maturity date for loans made after the effective date from two years to a minimum maturity of five years from the date on which the borrower applies for loan forgiveness. Existing PPP loans made before the new legislation retain their original two-year term, but may be renegotiated between a lender and a borrower to match the 5-year term permitted under the PPP Flexibility Act.

The Company used all of the loan proceeds from the PPP Loan to pay expenses during the covered period that the Company believes were for eligible purposes. On September 25, 2020, the Company submitted an application to the SBA through SVB for full loan forgiveness. On June 19, 2021, the Company received notification from SVB that the PPP Loan of $2.0 million has been fully forgiven by the SBA, and that payment and all accrued interest of $24,000 thereon were remitted by the SBA to SVB on June 16, 2021. In connection with the full loan forgiveness, the Company recorded a gain on extinguishment of debt of approximately $2.1 million in the three and six months ended June 30, 2021.

CRG Term Loan Agreement

On February 13, 2019 (the “CRG Closing Date”), the Company entered into the CRG Loan Agreement among the Company, as borrower, CRG Servicing LLC, as administrative agent and collateral agent (the “Agent”), and the lenders party thereto from time to time (the “Lenders”), providing for a senior secured term loan of up to $60 million (the “CRG Loan”). On the CRG Closing Date, $35 million of the CRG Loan was advanced (the “CRG Initial Advance”). The Company utilized the proceeds from the CRG Initial Advance for the repayment in full of all outstanding obligations under its prior credit agreement (the “SWK Credit Agreement”) with SWK Funding LLC (“SWK”). In April 2019, the Company exercised its option to borrow an additional $15 million of the CRG Loan (the “CRG Second Advance”). The Company did not draw any additional funds under the CRG Loan by the final draw deadline of March 31, 2020.

The CRG Loan is due and payable on December 31, 2023 (the “Maturity Date”). The CRG Loan bears interest at a fixed rate of 12.5% per annum payable in arrears on the last business day of each calendar quarter. The Company is required to make quarterly, interest only payments until the Maturity Date. So long as no default has occurred and is continuing, the Company may elect on each applicable interest payment date to pay 2.5% of the 12.5% per annum interest as Paid In-Kind (“PIK”), whereby such PIK amount would be added to the aggregate principal amount and accrue interest at 12.5% per annum. During the six months ended June 30, 2021, no PIK amounts had been added to the principal balance of the CRG Loan. In addition, the Company is required to pay an upfront fee of 1.5% of amounts borrowed under the CRG Loan (excluding any paid-in-kind amounts), which is payable as amounts are advanced under the CRG Loan. The Company will also be required to pay an exit fee equal to 6% of (i) the aggregate principal amounts advanced and (ii) PIK amounts issued, under the CRG Loan Agreement. In connection with the CRG Initial Advance, a 1.5% financing fee of $525,000 and an expense reimbursement of $350,000 were deducted from the net borrowing proceeds. In connection with the CRG Second Advance, a 1.5% financing fee of $225,000 was deducted from the net borrowing proceeds.

Upon the occurrence of a bankruptcy-related event of default, all amounts outstanding with respect to the CRG Loan become due and payable immediately, and upon the occurrence of any other Event of Default (as defined in the CRG Loan Agreement), all or any amounts outstanding with respect to the CRG Loan may become due and payable upon request of the Agent or majority Lenders. Subject to certain exceptions, the Company is required to make mandatory prepayments of the CRG Loan with the proceeds of assets sales and in the event of a change of control of the Company. In addition, the Company may make a voluntary prepayment of the CRG Loan, in whole or in part, at any time. All mandatory and voluntary prepayments of the CRG Loan are subject to the payment of prepayment premiums as follows: (i) if prepayment occurs on or prior to December 31, 2019, an amount equal to

10% of the aggregate outstanding principal amount of the CRG Loan being prepaid, (ii) if prepayment occurs after December 31, 2019 and on or prior to December 31, 2020, 5% of the aggregate outstanding principal amount of the CRG Loan being prepaid, which was waived on December 17, 2020 when the Company paid $15.0 million against the CRG Loan obligations in connection with the consummation of the RPA agreement (see Note 3), and (iii) if prepayment occurs after December 31, 2020 and on or prior to December 31, 2021, an amount equal to 3% of the aggregate outstanding principal amount of the CRG Loan being prepaid. No prepayment premium is due on any principal prepaid after December 31, 2021. Certain of the Company’s existing and future subsidiaries are guaranteeing the obligations of the Company under the CRG Loan Agreement. The obligations of the Company under the CRG Loan Agreement and the guarantee of such obligations are secured by a pledge of substantially all of the Company’s and the guarantors’ assets.

The CRG Loan Agreement contains affirmative and negative covenants customary for financings of this type, including limitations on our and our subsidiaries’ abilities, among other things, to incur additional debt, grant or permit additional liens, make investments and acquisitions, merge or consolidate with others, dispose of assets, pay dividends and distributions and enter into affiliate transactions, in each case, subject to certain exceptions. In addition, the CRG Loan Agreement contains the following financial covenants requiring the Company and the Guarantors to maintain:

• liquidity in an amount which shall exceed the greater of (i) $5 million and (ii) to the extent the Company has incurred certain permitted debt, the minimum cash balance, if any, required of the Company by the creditors of such permitted debt; and

• annual minimum product revenue from YUTIQ and DEXYCU: (i) for the twelve-month period beginning on January 1, 2019 and ending on December 31, 2019, of at least $15 million, (ii) for the twelve-month period beginning on January 1, 2020 and ending on December 31, 2020, of at least $45 million, (iii) for the twelve-month period beginning on January 1, 2021 and ending on December 31, 2021, of at least $80 million and (iv) for the twelve-month period beginning on January 1, 2022 and ending on December 31, 2022, of at least $90 million.

In November 2019, CRG waived the financial covenant associated with the Company’s revenue derived from sales of its products, DEXYCU and YUTIQ, for the twelve-month period ending December 31, 2019. In October 2020, CRG (i) waived the financial covenant associated with the Company’s revenue derived from sales of its products, DEXYCU and YUTIQ, for the twelve-month period ending December 31, 2020 and (ii) amended the financial covenant associated with the Company’s minimum product revenue to $45 million from $80 million, for the twelve-month period ending December 31, 2021. In May 2021, CRG further amended the financial covenant associated with the Company’s minimum product revenue to $25 million from $45 million, for the twelve-month period ending December 31, 2021. There were no other material changes to the CRG Loan Agreement and the Company incurred no incremental charges for the issuance of the waivers.

The total debt discount related to the CRG Initial Advance was approximately $3.2 million and consisted of (i) the accrual of a $2.1 million exit fee; (ii) the $525,000 upfront fee; and (iii) $591,000 of legal and other transaction costs. This amount is being amortized as additional interest expense over the term of the Loan using the effective interest rate method.

The total debt discount related to the CRG Second Advance was approximately $1.1 million and consisted of (i) the accrual of a $900,000 exit fee; and (ii) the $225,000 upfront fee. This amount is being amortized as additional interest expense over the term of the Loan using the effective interest rate method.

On December 17, 2020, the Company paid $15.0 million against the CRG Loan obligations in connection with the consummation of the RPA agreement (see Note 3). This payment included (i) a $13.8 million principal portion of the CRG Loan (ii) the $828,000 Exit Fee, and (iii) accrued and unpaid interest of $378,000 through that date. In connection with the partial prepayment of the CRG Loan, the Company recorded a loss on partial extinguishment of debt of $905,000 in the year ended December 31, 2020, associated with the write-off of the remaining balance of unamortized debt discount related to the partial prepayment of the CRG Loan.

Amortization of debt discount under the CRG Loan totaled $153,000 and $177,000 for the three months ended June 30, 2021 and 2020, respectively, and $300,000 and $348,000 for the six months ended June 30, 2021 and 2020, respectively.

Equity Incentive Plan

The 2016 Long-Term Incentive Plan (the “2016 Plan”), approved by the Company’s stockholders on December 12, 2016 (the “Adoption Date”), provides for the issuance of up to 300,000 shares of  the Company’s common stock reserved for issuance under the 2016 Plan plus any additional shares of the Company’s common stock that were available for grant under the 2008 Incentive Plan (the “2008 Plan”) at the Adoption Date or would otherwise become available for grant under the 2008 Plan as a result of subsequent termination or forfeiture of awards under the 2008 Plan. At the Company’s Annual Meeting of Stockholders held on June 25, 2019, the Company’s stockholders approved an amendment to the 2016 Plan to increase the number of shares authorized for issuance by 1,100,000 shares.

In January 2019, the Company expanded the terms of its annual stock option grants to include vesting ratable monthly over four years, or with 25% vesting after one year followed by ratable monthly vesting over three years. Previously, the Company’s option grants generally had ratable annual vesting over three years, or 1-year cliff vesting. Nonemployee awards are granted similar to the Company’s employee awards. All option grants have a 10-year term. Options to purchase a total of 170,283 shares of the Company’s common stock vested during the six months ended June 30, 2021. Starting February 2021, the Company (i) ceased vesting ratable monthly over four years and (ii) retained 25% vesting after one year followed by ratable monthly vesting over the remaining three years.

In determining the grant date fair value of option awards during the six months ended June 30, 2021, the Company applied the Black-Scholes option pricing model based on the following key assumptions:

Option life (in years)	4.75 - 6.08
Stock volatility	72.5% - 83.07%
Risk-free interest rate	0.42% - 1.18%
Expected dividends	0.0%

The following table summarizes information about employee, non-executive director and external consultant stock options for the six months ended June 30, 2021 (in thousands):

	Six Months

Weighted-average grant date fair value per share	$	8.41
Total cash received from exercise of stock options		10

Time-Vested Restricted Stock Units

Time-vested restricted stock unit awards (“RSUs”) issued to date under the 2016 Plan generally vest on a ratable annual basis over 3 years. The related stock-based compensation expense is recorded over the requisite service period, which is the vesting period. The fair value of all time-vested RSUs is based on the closing share price of the Company’s common stock on the date of grant.

The following table provides a reconciliation of RSU activity under the 2016 Plan for the six months ended June 30, 2021:

				Weighted
	Number of			Average
	Restricted			Grant Date
	Stock Units			Fair Value
Nonvested at January 1, 2021		149,004		$	13.85
Granted		227,141			13.06

Forfeited		(4,319	)		11.72
Nonvested at June 30, 2021		290,917		$	13.05

At June 30, 2021, the weighted average remaining vesting term of the RSUs was 1.51 years.

Deferred Stock Units

There were no non-vested deferred stock units (“DSUs”) issued and outstanding to the Company’s non-executive directors at each of June 30, 2021 and December 31, 2020, respectively. Each DSU vests one year from the date of grant. Subsequent to vesting, the DSUs will be settled in shares of the Company’s common stock upon the earliest to occur of (i) each director’s termination of service on the Company’s Board of Directors and (ii) the occurrence of a change of control as defined in the award agreement. At June 30, 2021, there were no vested DSUs that have not been settled in shares of the Company’s common stock.

Employee Stock Purchase Plan

On June 25, 2019, the Company’s stockholders approved the adoption of the EyePoint Pharmaceuticals, Inc. 2019 Employee Stock Purchase Plan (the “ESPP”) and authorized up to 110,000 shares of common stock reserved for issuance to participating employees. At the Company’s Annual Meeting of Stockholders held on June 22, 2021, the Company’s stockholders approved an amendment to the ESPP to increase the number of shares authorized for issuance by 250,000 shares. The ESPP allows qualified participants to purchase the Company’s common stock twice a year at 85% of the lesser of the average of the high and low sales price of the Company’s common stock on (i) the first trading day of the relevant offering period and (ii) the last trading day of the relevant offering period. The number of shares of the Company’s common stock each employee may purchase under this plan, when combined with all other employee stock purchase plans, is limited to the lower of an aggregate fair market value of $25,000 during each calendar year, or 5,000 shares of the Company’s common stock in any one offering period. The Company has maintained consecutive six-month offering periods since August 1, 2019. As of June 30, 2021, 27,713 shares of the Company’s common stock were issued pursuant to the ESPP.

The Company estimated the fair value of the option component of the ESPP shares at the date of grant using a Black-Scholes valuation model. During the three and six months ended June 30, 2021, the compensation expense from ESPP shares was immaterial.  

Stock-Based Compensation Expense

The Company’s consolidated statements of comprehensive loss included total compensation expense from stock-based payment awards for the three and six months ended June 30, 2021 and 2020, respectively, as follows (in thousands):

	Three Months Ended June 30,					Six Months Ended June 30,
	2021		2020			2021		2020
Compensation expense included in:
Research and development	$	255	$	(49	)	$	518	$	214

General and administrative		684		643			1,169		1,288
	$	1,180	$	735		$	2,168	$	1,895

At June 30, 2021, there was approximately $10.7 million of unrecognized compensation expense related to outstanding equity awards under the 2016 Plan, the 2008 Plan, the inducement awards and the ESPP that is expected to be recognized as expense over a weighted-average period of approximately 1.64 years.

Equinox Science, LLC

In February 2020, the Company entered into an Exclusive License Agreement with Equinox Science, LLC (“Equinox”), pursuant to which Equinox granted the Company an exclusive, sublicensable, royalty-bearing right and license to certain patents and other Equinox intellectual property to research, develop, make, have made, use, sell, offer for sale and import the compound vorolanib and any pharmaceutical products comprising the compound for the prevention or treatment of age-related macular degeneration, diabetic retinopathy and retinal vein occlusion using our proprietary localized delivery technologies, in each case, throughout the world except China, Hong Kong, Taiwan and Macau.

In consideration for the rights granted by Equinox, the Company (i) made a one time, non-refundable, non-creditable upfront cash payment of $1.0 million to Equinox in February 2020, and (ii) agreed to pay milestone payments totaling up to $50 million upon the achievement of certain development and regulatory milestones, consisting of (a) completion of a Phase II clinical trial for the compound or a licensed product, (b) the filing of a new drug application or foreign equivalent for the compound or a licensed product in the United States, European Union or United Kingdom and (c) regulatory approval of the compound or a licensed product in the United States, European Union or United Kingdom.

The Company also agreed to pay Equinox tiered royalties based upon annual net sales of licensed products in the specified territory. The royalties are payable with respect to a licensed product in a particular country in the specified territory on a country-by-country and licensed product-by-licensed product basis until the later of (i) twelve years after the first commercial sale of such licensed product in such country and (ii) the first day of the month following the month in which a generic product corresponding to such licensed product is launched in such country. The royalty rates range from the high-single digits to low-double digits depending on the level of annual net sales. The royalty rates are subject to reduction during certain periods when there is no valid patent claim that covers a licensed product in a particular country.

The Company recorded $0 and $1.0 million of R&D expense for the three and six months ended June 30, 2020, respectively, due to the early stage of its preclinical drug development studies. No additional charge was recorded for the three and six months ended June 30, 2021.

Financial instruments that potentially subject the Company to concentrations of credit risk have historically consisted principally of cash and cash equivalents. At June 30, 2021 and December 31, 2020, substantially all of the Company’s interest-bearing cash equivalent balances were concentrated in one U.S. Government institutional money market fund that has investments consisting primarily of U.S. Government Agency debt, U.S. Treasury Repurchase Agreements and U.S. Government Agency Repurchase Agreements. These deposits may be redeemed upon demand and, therefore, generally have minimal risk. The Company’s cash equivalents are classified within Level 1 on the basis of valuations using quoted market prices.   

The carrying amounts of accounts receivable, accounts payable and accrued expenses approximate fair value because of their short-term maturity.

The fair value of the Company’s CRG Loan is determined using a discounted cash flow analysis based on market rates for observable similar instruments as of the condensed consolidated balance sheet dates. Accordingly, the fair value of the CRG Loan is categorized as Level 2 within the fair value hierarchy. At June 30 2021, the fair value of the CRG Loan was approximately $38.4 million, and the carrying value of the CRG Loan was approximately $38.5 million, and consisted of $36.2 million of its carrying amount as reported in long-term debt, and $2.3 million of debt exit fee as reported in other long-term liabilities of the condensed consolidated balance sheet, respectively. At December 31, 2020, the fair value of the CRG Loan was approximately $38.0 million, and the carrying value of the CRG Loan was approximately $38.3 million, and consisted of $36.0 million of its carrying amount as reported in long-term debt, and $2.3 million of debt exit fee as reported in other long-term liabilities of the condensed consolidated balance sheet, respectively.

Net Loss per Share

14. Net Loss per Share

Basic net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding during the period. For periods in which the Company reports net income, diluted net income per share is determined by adding to the basic weighted average number of common shares outstanding the total number of dilutive common equivalent shares using the treasury stock method, unless the effect is anti-dilutive. Potentially dilutive shares were not included in the calculation of diluted net loss per share for each of the three and six months ended June 30, 2021 and 2020 as their inclusion would be anti-dilutive.

Potential common stock equivalents excluded from the calculation of diluted earnings per share because the effect would have been anti-dilutive were as follows:

Revenue Recognition

Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, Revenue from Contracts with Customers (“ASC 606”), the Company 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. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract, determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

Product sales, net — The Company sells YUTIQ and DEXYCU to a limited number of specialty distributors and specialty pharmacies (collectively the “Distributors”) in the U.S., with whom the Company has entered into formal agreements, for delivery to physician practices for YUTIQ and to hospital outpatient departments and ambulatory surgical centers for DEXYCU. The Company recognizes revenue on sales of its products when Distributors obtain control of the products, which occurs at a point in time, typically upon delivery. In addition to agreements with Distributors, the Company also enters into arrangements with healthcare providers, ambulatory surgical centers, and payors that provide for government mandated and/or privately negotiated rebates, chargebacks, and discounts with respect to the purchase of the Company’s products from Distributors.

Reserves for variable consideration — Product sales are recorded at the wholesale acquisition costs, net of applicable reserves for variable consideration. Components of variable consideration include trade discounts and allowances, provider chargebacks and discounts, payor rebates, product returns, and other allowances that are offered within contracts between the Company and its Distributors, payors, and other contracted purchasers relating to the Company’s product sales. These reserves, as detailed below, are based on the amounts earned, or to be claimed on the related sales, and are classified either as reductions of product revenue and accounts receivable or a current liability, depending on how the amount is to be settled. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the respective underlying contracts. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results in the future vary from the estimates, the Company adjusts these estimates, which would affect product revenue and earnings in the period such variances become known.

Distribution fees — The Company compensates its Distributors for services explicitly stated in the Company’s contracts and are recorded as a reduction of revenue in the period the related product sale is recognized.

Provider chargebacks and discounts — Chargebacks are discounts that represent the estimated obligations resulting from contractual commitments to sell products at prices lower than the list prices charged to the Company’s Distributors. These Distributors charge the Company for the difference between what they pay for the product and the Company’s contracted selling price. These reserves are established in the same period that the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability. Reserves for chargebacks consist of amounts that the Company expects to pay for units that remain in the distribution channel inventories at each reporting period-end that the Company expects will be sold under a contracted selling price, and chargebacks that Distributors have claimed, but for which the Company has not yet settled.

Government rebates — The Company is 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 condensed consolidated balance sheets. The Company’s 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.

Payor rebates — The Company contracts with certain private payor organizations, primarily insurance companies, for the payment of rebates with respect to utilization of its products. The Company estimates these rebates and records such estimates in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability.

Co-Payment assistance — The Company offers co-payment assistance to commercially insured patients meeting certain eligibility requirements. The calculation of the accrual for co-pay assistance is based on an estimate of claims and the cost per claim that the Company expects to receive associated with product that has been recognized as revenue.

Product returns — The Company generally offers a limited right of return based on its returned goods policy, which includes damaged product and remaining shelf life. The Company estimates the amount of its product sales that may be returned and records this estimate as a reduction of revenue in the period the related product revenue is recognized, as well as reductions to trade receivables, net on the condensed consolidated balance sheets.

License and collaboration agreement revenue — The Company analyzes each element of its license and collaboration arrangements to determine the appropriate revenue recognition. The terms of the license agreement may include payment to the Company of non-refundable up-front license fees, milestone payments if specified objectives are achieved, and/or royalties on product sales. The Company recognizes revenue from upfront payments at a point in time, typically upon fulfilling the delivery of the associated intellectual property to the customer.

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations.

The Company recognizes sales-based milestone payments as revenue upon the achievement of the cumulative sales amount specified in the contract in accordance with ASC 606-10-55-65. For those milestone payments which are contingent on the occurrence of particular future events, the Company determines that these need to be considered for inclusion in the calculation of total consideration from the contract as a component of variable consideration using the most-likely amount method. As such, the Company assesses each milestone to determine the probability and substance behind achieving each milestone. Given the inherent uncertainty associated with these future events, the Company will not recognize revenue from such milestones until there is a high probability of occurrence, which typically occurs near or upon achievement of the event.

When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component.

Applying the practical expedient in paragraph 606-10-32-18, the Company does not assess whether a significant financing component exists if the period between when the Company performs its obligations under the contract and when the customer pays is one year or less. None of the Company’s contracts contained a significant financing component as of June 30, 2021.

Royalties — The Company recognizes revenue from license arrangements with its commercial partners’ net sales of products. Such revenues are included as royalty income. In accordance with ASC 606-10-55-65, royalties are recognized when the subsequent sale of the commercial partner’s products occurs. The Company’s commercial partners are obligated to report their net product sales and the resulting royalty due to the Company typically within 60 days from the end of each quarter. Based on historical product sales, royalty receipts and other relevant information, the Company recognizes royalty income each quarter and subsequently determines a true-up when it receives royalty reports and payment from its commercial partners. Historically, these true-up adjustments have been immaterial.

Sale of Future Royalties — The Company has sold its rights to receive certain royalties on product sales. In the circumstance where the Company has sold its rights to future royalties under a royalty purchase agreement and also maintains limited continuing involvement in the arrangement (but not significant continuing involvement in the generation of the cash flows that are due to the purchaser), the Company defers recognition of the proceeds it receives for the sale of royalty streams and recognizes such unearned revenue as revenue under the units-of-revenue method over the life of the underlying license agreement. Under the units-of-revenue method, amortization for a reporting period is calculated by computing a ratio of the proceeds received from the purchaser to the total payments expected to be made to the purchaser over the term of the agreement, and then applying that ratio to the period’s cash payment.

Estimating the total payments expected to be received by the purchaser over the term of such arrangements requires management to use subjective estimates and assumptions. Changes to the Company’s estimate of the payments expected to be made to the purchaser over the term of such arrangements could have a material effect on the amount of revenues recognized in any particular period.

Research Collaborations — The Company recognizes revenue over the term of the statements of work under any funded research collaborations. Revenue recognition for consideration, if any, related to a license option right is assessed based on the terms of any such future license agreement or is otherwise recognized at the completion of the research collaborations.

Please refer to Note 3 for further details on the license and collaboration agreements into which the Company has entered and corresponding amounts of revenue recognized during the current and prior year periods.

Cost of sales, excluding amortization of acquired intangible assets — Cost of sales, excluding amortization of acquired intangible assets, consist of costs associated with the manufacture of YUTIQ and DEXYCU, certain period costs, product shipping and, as applicable, royalty expense. The inventory costs for YUTIQ include purchases of various components, the active pharmaceutical ingredient (“API”) and internal labor and overhead for the product manufactured in the Company’s Watertown, MA facility. The inventory costs for DEXYCU include purchased components, the API and third-party manufacturing and assembly.

Debt Instrument Description										The Paycheck Protection Program Flexibility Act of 2020 (the “PPP Flexibility Act”), enacted on June 5, 2020, amended the Paycheck Protection Program, among others, as follows: (i) extended the covered period from 8 weeks to the earlier of 24 weeks from the date the PPP Loan is originated and December 31, 2020, during which PPP funds needed to be expended in order to be forgiven. A borrower may submit a loan forgiveness application any time on or before the maturity date of the loan – including before the end of the covered period – if the borrower has used all of the loan proceeds for which the borrower is requesting forgiveness; (ii) at least 60% of PPP funds must be spent on payroll costs, with the remaining 40% available to spend on other eligible expenses; (iii) payments are deferred until the date on which the amount of forgiveness determined is remitted to the lender. If a borrower fails to seek forgiveness within 10 months after the last day of its covered period, then payments will begin on the date that is 10 months after the last day of the covered period. In addition, the PPP Flexibility Act modified the CARES Act by increasing the maturity date for loans made after the effective date from two years to a minimum maturity of five years from the date on which the borrower applies for loan forgiveness. Existing PPP loans made before the new legislation retain their original two-year term, but may be renegotiated between a lender and a borrower to match the 5-year term permitted under the PPP Flexibility Act.
