Notes to Condensed Financial Statements ( in thousands, except share and per share amounts) (Unaudited) Note 1 — Company Overview Eton Pharmaceuticals, Inc. (“Eton” or the “Company”) was incorporated as a Delaware “C” corporation on April 27, 2017 and was initially set up as a wholly-owned subsidiary of Harrow Health, Inc. (“Harrow”, fka Imprimis Pharmaceuticals, Inc.). In June 2017, the Company raised $20,055 in start-up capital through a private sale of preferred stock and a separate management team was then established for Eton with its corporate offices located in Deer Park, Illinois. In November 2018, the Company completed its initial public offering (the “IPO”) and received net proceeds of $21,960, after deducting underwriting discounts and commissions and offering-related expenses. In November 2019, the Company entered into a credit agreement and received net proceeds of $4,750 and in August 2020 the Company received net proceeds of $1,965 under the credit agreement (see Note 5). In March and April 2020, Eton received net proceeds of $7,756 from the sale of shares of its common stock in a private placement and in October 2020, the Company received net proceeds of $21,026 from a public offering for its common stock at an offering price of $7.00 per share. Eton is a specialty pharmaceutical company focused on developing, acquiring, and commercializing innovative products. Eton is primarily focused on hospital injectable and pediatric rare disease products. The Company seeks to improve the formula, delivery system, or safety of existing molecules in order to address unmet patient needs. Eton pursues what it perceives to be low-risk product candidates where existing published literature, historical clinical trials, or physician usage has established safety and/or efficacy of the molecule, thereby reducing the incremental clinical burden required for the Company to bring the product to patients. The Company’s Biorphen® product was approved by the FDA in October 2019 and sales commenced for this product at the end of 2019. Eton’s EM-100 product was sold to Bausch Health and the product was approved by the FDA in September 2020. Bausch Health launched this product under the name of Alaway® Preservative Free in January 2021 and Eton will receive royalties from the sale of the product. In addition, the Company acquired the licensing rights to Alkindi Sprinkle and this product was approved by the FDA in October 2020 and launched in December 2020. In February 2021, the Company sold three pediatric neurology products it had under development to Azurity Pharmaceuticals (“Azurity”) and anticipates additional revenues from Azurity based on various product-related milestones including the commercial launch for these products which are currently under review with the FDA. Note 2 — Liquidity Considerations Prior to 2021, the Company had generated limited revenues and had incurred negative cash flows from operating activities since its inception in 2017. In the first three months of 2021, the Company generated net cash provided by operating activities of $3,715 primarily from the initial proceeds from the sale of three neurology products. The Company expects further growth in 2021 and beyond in accordance with additional market penetration from its approved products plus additional revenues from licensing and additional products where it anticipates FDA approval. The Company currently believes its existing cash and cash equivalents of $25,113 as of March 31, 2021 will be sufficient to fund its operating expenses and capital expenditure requirements for at least the next twelve months from the date of filing of this quarterly report. This estimate is based on the Company’s current assumptions, including assumptions relating to estimated sales and its ability to manage its spending. The Company could use its available capital resources sooner than currently expected. Accordingly, the Company could seek to obtain additional capital through equity financings, the issuance of debt or other arrangements. However, there can be no assurance that the Company will be able to raise additional capital if needed or under acceptable terms, if at all. The sale of additional equity may dilute existing stockholders and newly issued shares could contain senior rights and preferences compared to currently outstanding common shares. The Company’s existing long-term debt obligation contains covenants and limits the Company’s ability to pay dividends or make other distributions to stockholders. If the Company experiences delays in product sales growth and completing its product development and obtaining regulatory approval for its other product candidates and is unable to obtain such additional financing, operations would need to be scaled back or discontinued. Note 3 — Summary of Significant Accounting Policies Basis of Presentation The Company has prepared the accompanying financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). 5 Eton Pharmaceuticals, Inc. Notes to Condensed Financial Statements ( in thousands, except share and per share amounts) (Unaudited) Note 3 — Summary of Significant Accounting Policies (continued) Unaudited Interim Financial Information The accompanying interim condensed financial statements are unaudited and have been prepared on the same basis as the audited financial statements and, in the opinion of management, reflect all adjustments necessary for the fair presentation of the Company’s financial position as of March 31, 2021 and the results of its operations and its cash flows for the periods ended March 31, 2021 and 2020. The financial data and other information disclosed in these notes related to the three-month periods ended March 31, 2021 and 2020 are also unaudited. The results for the three-month period ended March 31, 2021 are not necessarily indicative of results to be expected for the year ending December 31, 2021, any other interim periods or any future year or period. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Significant estimates and assumptions reflected in these financial statements include, but are not limited to, provisions for uncollectible receivables and sales returns, valuation of inventories, useful lives of assets and the impairment of property and equipment, the accrual of research and development expenses and the valuation of common stock, stock options and warrants. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates or assumptions. Segment Information The Company operates the business on the basis of a single reportable segment, which is the business of developing and commercializing prescription drug products. The Company’s chief operating decision-maker is the Chief Executive Officer (“CEO”), who evaluates the Company as a single operating segment. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. All cash and cash equivalents are held in U.S. financial institutions or invested in short-term U.S. treasury bills. Cash equivalents consist of an interest-bearing checking account and a U.S. treasury bill. From time to time, amounts deposited with its bank exceed federally insured limits. The Company believes the associated credit risk to be minimal. Accounts Receivable Accounts receivable are recorded at the invoiced amount and are non-interest bearing. Accounts receivable are recorded net of allowances for doubtful accounts, cash discounts for prompt payment, distribution fees, chargebacks and returns and allowances. The total for these reserves amounted to $71 and $71 as of March 31, 2021 and December 31, 2020, respectively. Inventories The Company values its inventories at the lower of cost or net realizable value using the first-in, first-out method of valuation. The Company reviews its inventories for potential excess or obsolete issues on an ongoing basis and will record a write-down if an impairment is identified. Inventories at March 31, 2021 and December 31, 2020 consist solely of purchased finished goods. At both March 31, 2021 and December 31, 2020 inventories are shown net of a slow-moving reserve for its Biorphen product of $623 due to the risk of expiry before this entire stock of inventories is sold. 6 Eton Pharmaceuticals, Inc. Notes to Condensed Financial Statements ( in thousands, except share and per share amounts) (Unaudited) Note 3 — Summary of Significant Accounting Policies (continued) Property and Equipment Property and equipment are stated at cost. Depreciation of property and equipment is computed utilizing the straight-line method based on the following estimated useful lives: computer hardware and software is depreciated over three years; equipment, furniture and fixtures is depreciated over five years; leasehold improvements are amortized over their estimated useful lives or the remaining lease term, whichever is shorter. Construction in progress is capitalized but not depreciated until it is placed into service. Maintenance and repairs are charged to expense as incurred, while renewals and improvements are capitalized. In March 2021, the Company completed an evaluation of its expected needs for product development and testing activities and determined that it would discontinue its laboratory operation in Lake Zurich, Illinois. The Company expects to complete a sale of the lab equipment in May 2021 at a price in excess of the book value for these assets. Accordingly, the $551 net book value of these assets was removed from the property and equipment classification and is classified as a current asset, Equipment held-for-sale, in the Company’s accompanying condensed balance sheet as of March 31, 2021. Intangible Assets The Company capitalizes payments it makes for licensed products when the payment is based on FDA approval for the product and the cost is recoverable based on expected future cash flows from the product. The cost is amortized on a straight-line basis over the estimated useful life of the product commencing on the approval date in accordance with Accounting Standards Codification (“ASC”) 350 — Intangibles - Goodwill and Other. A $750 payment related to the approval of the Company’s Biorphen product in 2019 has been capitalized and that cost is being amortized over five years. The intangible assets, net on the Company’s balance sheet reflected $213 of accumulated amortization as of March 31, 2021. The Company recorded $38 of amortization expense for the three months ended March 31, 2021. The Company will record amortization expense of $150 per year for this intangible asset for 2021 through 2023 and then $125 in 2024 when it will be fully amortized. Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the Company’s statements of operations for the amount by which the carrying amount of the asset exceeds the fair value of the asset. No impairment has been recognized since the Company’s inception in 2017. Debt Issuance Costs and Debt Discount and Detachable Debt-Related Warrants Costs incurred to issue debt are deferred and recorded as a reduction to the debt balance in the accompanying balance sheets. The Company amortizes debt issuance costs over the expected term of the related debt using the effective interest method. Debt discounts relate to the relative fair value of warrants issued in conjunction with the debt and are also recorded as a reduction to the debt balance and accreted over the expected term of the debt to interest expense using the effective interest method. Revenue Recognition for Contracts with Customers The Company accounts for contracts with its customers in accordance with ASC 606 — Revenue from Contracts with Customers. ASC 606 applies to all contracts with customers, except for contracts that are within the scope of other standards. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to 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, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. 7 Eton Pharmaceuticals, Inc. Notes to Condensed Financial Statements ( in thousands, except share and per share amounts) (Unaudited) Note 3 — Summary of Significant Accounting Policies (continued) 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 and 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. Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. The Company assesses whether these options provide a material right to the customer and, if so, they are considered performance obligations. The exercise of a material right is accounted for as a contract modification for accounting purposes. The Company recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) each performance obligation is satisfied at a point in time or over time, and if over time this is based on the use of an output or input method. Any amounts received prior to revenue recognition will be recorded as deferred revenue. Amounts expected to be recognized as revenue within the twelve months following the balance sheet date will be classified as current portion of deferred revenue in the Company’s balance sheets. Amounts not expected to be recognized as revenue within the twelve months following the balance sheet date are classified as long-term deferred revenue, net of current portion. Milestone Payments – If a commercial contract arrangement includes development and regulatory milestone payments, the Company will evaluate whether the milestone conditions have been achieved and if it is probable that a significant revenue reversal would not occur before recognizing the associated revenue. Milestone payments that are not within the Company’s control or the licensee’s control, such as regulatory approvals, are generally not considered probable of being achieved until those approvals are received. Royalties – For arrangements that include sales-based royalties, including milestone payments based on a level of sales, which are the result of a customer-vendor relationship and for which the license is deemed to be the predominant item to which the royalties relate, the Company will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied or partially satisfied. To date, the Company has not recognized any royalty revenue resulting from any of its licensing arrangements. Significant Financing Component – In determining the transaction price, the Company will adjust consideration for the effects of the time value of money if the expected period between payment by the licensees and the transfer of the promised goods or services to the licensees will be more than one year. The Company sells Biorphen in the U.S. to wholesale pharmaceutical distributors, who then sell the product to hospitals and other end-user customers. Sales to wholesalers are made pursuant to purchase orders subject to the terms of a master agreement, and delivery of individual shipments of Biorphen represent performance obligations under each purchase order. The Company uses a third-party logistics (“3PL”) vendor to process and fulfill orders and has concluded it is the principal in the sales to wholesalers because it controls access to the 3PL vendor services rendered and directs the 3PL vendor activities. The Company has no significant obligations to wholesalers to generate pull-through sales. In addition, the Company sells its Alkindi Sprinkle product to one pharmacy distributor customer which provides order fulfilment and inventory storage/distribution services. Selling prices initially billed to wholesalers are subject to discounts for prompt payment and subsequent chargebacks when the wholesalers sell Biorphen at negotiated discounted prices to members of certain group purchasing organizations (“GPOs”) and government programs. In addition, the Company pays fees to wholesalers for their distribution services, inventory reporting and chargeback processing. The Company pays GPOs fees for administrative services and for access to GPO members and concluded the benefits received in exchange for these fees are not distinct from its sales of Biorphen, and accordingly it applies these amounts to reduce revenues. Wholesalers also have rights to return unsold product nearing or past the expiration date. Because of the shelf life of Biorphen and the Company’s lengthy return period, there may be a significant period of time between when the product is shipped and when it issues credits on returned product. For its Alkindi Sprinkle product, the Company bills at the initial product list price which are subject to offsets for patient co-pay assistance and potential state Medicaid reimbursements which are recorded as a reduction of net revenues at the date of sale/shipment. 8 Eton Pharmaceuticals, Inc. Notes to Condensed Financial Statements ( in thousands, except share and per share amounts) (Unaudited) Note 3 — Summary of Significant Accounting Policies (continued) The Company estimates the transaction price when it receives each purchase order taking into account the expected reductions of the selling price initially billed to the wholesaler/distributor arising from all of the above factors. The Company has developed estimates for future returns and chargebacks of Biorphen and the impact of the other discounts and fees it pays while Alkindi Sprinkle sales to its distributor are not subject to returns. When estimating these adjustments to the transaction price, the Company reduces it sufficiently to be able to assert that it is probable that there will be no significant reversal of revenue when the ultimate adjustment amounts are known. The Company recognizes revenue from Biorphen product sales and related cost of sales upon product delivery to the wholesaler location. At that time, the wholesalers take control of the product as they take title, bear the risk of loss of ownership, and have an enforceable obligation to pay the Company. They also have the ability to direct sales of product to their customers on terms and at prices they negotiate. Although wholesalers have product return rights, the Company does not believe they have a significant incentive to return the product. The Company stores its Alkindi Sprinkle inventory at its pharmacy distributor customer location and sales are recorded when stock is pulled and shipped to fulfill specific patient orders. Upon recognition of revenue from product sales, the estimated amounts of credit for product returns, chargebacks, distribution fees, prompt payment discounts, state Medicaid and GPO fees are included in sales reserves, accrued liabilities and net of accounts receivable. The Company monitors actual product returns, chargebacks, discounts and fees subsequent to the sale. If these amounts end up differing from its estimates, it will make adjustments to these allowances, which are applied to increase or reduce product sales revenue and earnings in the period of adjustment. In addition, the Company receives revenues from product licensing agreements where it has contracted for milestone payments and royalties from products it has developed or for which it has acquired the rights to a product developed by a third party. Revenues for the three months ended March 31, 2021 reflected $11,500 of licensing milestone fees, $254 in product sales and $143 in royalty revenue. Revenues for the three months ended March 31, 2020 consisted solely of product sales. Cost of Sales Cost of sales consists of the profit-sharing and royalty fees with the Company’s product licensing and development partners, the purchase costs for finished products from third-party manufacturers and freight and handling/storage costs from the Company’s 3PL logistics service providers. The cost of sales for profit-sharing and royalty fees and costs for purchased finished products and the associated inbound freight expense is recorded when the associated product sale revenue is recognized in accordance with the terms of shipment to customers while outbound freight and handling/storage fees charged by the 3PL service provider are expensed as they are incurred. Cost of sales also reflects any write-downs or reserve adjustments for the Company’s inventories. Research and Development Expenses Research and development (“R&D”) expenses include both internal R&D activities and external contracted services. Internal R&D activity expenses include salaries, benefits and stock-based compensation and other costs to support the Company’s R&D operations. External contracted services include product development efforts such as certain product licensor milestone payments, clinical trial activities, manufacturing and control-related activities and regulatory costs. R&D expenses are charged to operations as incurred. The Company reviews and accrues R&D expenses based on services performed and relies upon estimates of those costs applicable to the stage of completion of each project. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. Upfront payments and milestone payments made for the licensing of technology for products that are not yet approved by the FDA are expensed as R&D in the period in which they are incurred. Nonrefundable advance payments for goods or services to be received in the future for use in R&D activities are recorded as prepaid expenses and are expensed as the related goods are delivered or the services are performed. 9 Eton Pharmaceuticals, Inc. Notes to Condensed Financial Statements ( in thousands, except share and per share amounts) (Unaudited) Note 3 — Summary of Significant Accounting Policies (continued) Income (Loss) Per Share Basic net income (loss) per common share is computed by dividing net income (loss) attributable to common stockholders for the period by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing the net income (loss) attributable to common stockholders for the period by the weighted average number of common and common equivalent shares, such as unvested restricted stock, stock options and warrants that are outstanding during the period. Common stock equivalents are excluded from the computation when their inclusion would be anti-dilutive. Common stock equivalents (using the treasury stock and “if converted” method) from stock options, unvested RSAs and warrants at March 31, 2021 were 2,093,952 and excluded 729,692 shares that were anti-dilutive. For the three-month period ended March 31, 2020, common stock equivalents of 3,588,523 are excluded from the calculation of diluted net loss per share because the effect is anti-dilutive. Included in the basic and diluted net income (loss) per share calculation are RSUs awarded to directors that have vested, but the issuance and delivery of the common shares are deferred until the director retires from service as a director (see Note 8). Stock-Based Compensation The Company accounts for stock-based compensation under the provisions of ASC 718 — Compensation — Stock Compensation. The guidance under ASC 718 requires companies to estimate the fair value of the stock-based compensation awards on the date of grant and record expense over the related service periods, which are generally the vesting period of the equity awards. The Company estimates the fair value of stock-based option awards using the Black-Scholes-Merton option-pricing model (“BSM”). The BSM requires the input of subjective assumptions, including the expected stock price volatility, the calculation of expected term, forfeitures and the fair value of the underlying common stock on the date of grant, among other inputs. The risk-free interest rate was determined from the implied yields for zero-coupon U.S. government issues with a remaining term approximating the expected life of the options or warrants. Dividends on common stock are assumed to be zero for the BSM valuation of the stock options. The expected term of stock options granted is based on vesting periods and the contractual life of the options. Expected volatilities are based on comparable companies’ historical volatility along with a limited weighting included for the Company’s own volatility subsequent to its IPO, which management believes represents the most accurate basis for estimating expected future volatility under the current conditions. The Company accounts for forfeitures as they occur. Fair Value Measurements We measure certain of our assets and liabilities at fair value. Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value accounting requires characterization of the inputs used to measure fair value into a three-level fair value hierarchy as follows: Level 1 — Inputs based on quoted prices in active markets for identical assets or liabilities. An active market is a market in which transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 — Observable inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent from the entity. Level 3 — Unobservable inputs that reflect the entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available. Fair value measurements are classified based on the lowest level of input that is significant to the measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of the assets and liabilities and their placement within the fair value hierarchy levels. The determination of the fair values stated below take into account the market for the Company’s financials, assets and liabilities, the associated credit risk and other factors as required. The Company considers active markets as those in which transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis. 10 Eton Pharmaceuticals, Inc. Notes to Condensed Financial Statements ( in thousands, except share and per share amounts) (Unaudited) Note 3 — Summary of Significant Accounting Policies (continued) The Company’s financial instruments included cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, PPP loan and long-term debt obligation. The carrying amounts of these financial instruments, except for the PPP loan and long-term debt obligation, approximate their fair values due to the short-term maturities of these instruments. Based on borrowing rates currently available to the Company, the carrying value of the PPP loan and long-term debt obligation approximate their fair values. Impact of New Accounting Pronouncements There were no new accounting pronouncements issued by the FASB during the current period that would apply to the Company and have a material impact on its financial position or results of operations. Subsequent Events The Company has evaluated subsequent events through the filing date of this Form 10-Q and has determined that no subsequent events have occurred that would require recognition in the condensed financial statements or disclosure in the notes thereto.

Notes to Condensed Financial Statements ( in thousands, except share and per share amounts) (Unaudited) Note 5 — Long Term Debt SWK Loan On November 13, 2019, the Company entered into a credit agreement (the “SWK Credit Agreement”) with SWK Holdings Corporation (“SWK”) which provided for up to $10,000 in financing. The Company received proceeds of $5,000 at closing and was able to borrow an additional $5,000 upon the FDA approval of a second product developed by the Company, excluding EM-100. In March 2020, in conjunction with the Company’s Alkindi Sprinkle product licensing agreement (see Note 11) and the Company’s March 2020 sale of additional shares of its common stock, the Company and SWK amended the SWK Credit Agreement. The amendment provided the Company with the option to immediately draw $2,000 and the ability to borrow an additional $3,000 based upon the FDA approval of EM-100 and Alkindi Sprinkle which subsequently occurred in September 2020. Accordingly, the Company borrowed an additional $2,000 on August 11, 2020. The term of the SWK Credit Agreement is for five years and borrowings bear interest at a rate of LIBOR 3-month plus 10.0%, subject to a stated LIBOR floor rate of 2.0%. A 2.0% unused credit limit fee is assessed during the first twelve months after the date of the SWK Credit Agreement and loan fees include a 5.0% exit fee based on the principal amounts drawn which is payable at the end of the term of the SWK Credit Agreement. The Company is required to maintain a minimum cash balance of $3,000, will only pay interest on the debt until February14, 2022 and then will pay 5.5% of the loan principal balance commencing on February 15, 2022 and then every three months thereafter until November 13, 2024 at which time the remaining principal balance is due. Borrowings under the SWK Credit Agreement are secured by the Company’s assets. The SWK Credit Agreement contains customary default provisions and covenants which include limits on additional indebtedness. In March 2020, SWK provided a waiver for the Company to obtain loans with the Small Business Association. The Company is currently in the process of negotiating covenant targets for EBITDA and revenue for the SWK Credit Agreement. In February 2021, the Company notified SWK that it will not require additional borrowing capacity under the SWK Credit Agreement and terminated the additional borrowing capacity with SWK. In connection with the initial $5,000 borrowed in November 2019, the Company issued warrants to SWK to purchase 51,239 shares of the Company’s common stock with an exercise price of $5.86 per share. The relative fair value of these 51,239 warrants was $226 and was estimated using the Black-Scholes-Merton option pricing model with the following assumptions: fair value of the Company’s common stock at issuance of $5.75 per share; seven-year contractual term; 95% volatility; 0% dividend rate; and a risk-free interest rate of 1.8%. In connection with the additional $2,000 borrowed in August 2020, the Company issued warrants for 18,141 shares of its common stock at an exercise price of $6.62 per share. The relative fair value of the 18,141 warrants was $94 and was estimated using the Black-Scholes-Merton option pricing model with the following assumptions: fair value of the Company’s common stock at issuance of $6.85 per share; seven-year contractual term; 95% volatility; 0% dividend rate; and a risk-free interest rate of 0.4%. These warrants (the “SWK Warrants”) are exercisable immediately and have a term of seven years from the date of issuance. The SWK Warrants are subject to a cashless exercise feature, with the exercise price and number of shares issuable upon exercise subject to change in connection with stock splits, dividends, reclassifications and other conditions. Interest expense of $264 was recorded during the three months ended March 31, 2021, which included $36 of debt discount amortization. Interest expense of $195 was recorded during the three months ended March 31, 2020, which included $27 of debt discount amortization. As of March 31, 2021, $62 of accrued interest is included in accrued liabilities. 12 Eton Pharmaceuticals, Inc.

Notes to Condensed Financial Statements ( in thousands, except share and per share amounts) (Unaudited) Note 8 — Share-Based Payment Awards The Company’s board of directors and stockholders approved the Eton Pharmaceuticals, Inc. 2017 Equity Incentive Plan in May 2017 (the “2017 Plan”), which authorized the issuance of up to 5,000,000 shares of the Company’s common stock. In conjunction with the Company’s IPO in November 2018, the Company’s stockholders and board of directors approved the 2018 Equity Incentive Plan (the “2018 Plan”) which succeeded the 2017 Plan. The Company has granted restricted stock awards (“RSAs”), stock options and restricted stock units (“RSUs”) for its common stock under the 2017 Plan and 2018 Plan as detailed in the tables below. There were 1,370,758 shares available for future issuance under the 2018 Plan as of March 31, 2021. Shares that are expired, terminated, surrendered or canceled without having been fully exercised will be available for future awards under the 2018 Plan. In addition, the 2018 Plan provides that commencing January 1, 2019 and through January 1, 2028, the share reserve will be increased annually by 4% of the total number of shares of common stock outstanding as of the preceding December 31, subject to a reduction at the discretion of the Company’s board of directors. The exercise price for stock options granted is not less than the fair value of common stock as determined by the board of directors as of the date of grant. The Company uses the closing stock price on the date of grant as the exercise price. During the third quarter of 2017, the Company issued 25,000 RSU’s to each of its four outside directors (100,000 total share units). The RSU’s issued to the outside directors were 100% vested at June 30, 2018. The associated 100,000 shares of the Company’s common stock will not be issued until the individual director retires from service from the Company’s board of directors. The Company has not issued any additional RSU’s. To date, all stock options issued have been non-qualified stock options, and the exercise prices were set at the fair value for the shares at the dates of grant. Options typically have a ten-year life, except for options to purchase 50,000 shares of the Company’s common stock granted to product consultants in July 2017 that expire within five years if the Company is not able to file certain product submissions to the FDA prior to the five-year expiration date. Furthermore, these option awards to the Company’s product consultants do not vest unless certain product submissions are made to the FDA, and accordingly, the Company has not recorded any expense for these contingently vesting option awards to its product consultants. For the three months ended March 31, 2021 and 2020, the Company’s total stock-based compensation expense was $673 and $365, respectively. Of these amounts, $581 and $325 was recorded in general and administrative expenses, respectively, and $92 and $40 was recorded in research and development expenses, respectively. A summary of stock option activity is as follows: Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (Yrs) Aggregate Intrinsic Value Options outstanding as of December 31, 2020 2,824,500 $ 4.05 8.3 $ 11,525 Issued — $ Exercised (75,000 ) $ 1.38 Forfeited/Cancelled — $ Options outstanding as of March 31, 2021 2,749,500 $ 4.12 8.1 $ 8,844 Options exercisable at March 31, 2021 1,412,648 $ 4.13 7.8 $ 4,506 Options vested and expected to vest at March 31, 2021 2,699,500 $ 4.17 8.2 $ 8,547 The aggregate intrinsic value of stock options is calculated as the difference between the exercise price of the stock options and the fair value of the Company’s common stock for those stock options that had strike prices lower than the fair value of the Company’s common stock. 15 Eton Pharmaceuticals, Inc. Notes to Condensed Financial Statements ( in thousands, except share and per share amounts) (Unaudited) Note 8 — Share-Based Payment Awards (continued) As of March 31, 2021, there was a total of $3,749 of unrecognized compensation costs related to non-vested stock option awards. In the three-month period ended March 31, 2021, stock option exercises totaled 75,000 shares at an exercise price of $1.38 per share with an intrinsic value of $416. In the three-month period ended March 31, 2020, stock option exercises totaled 5,000 shares at an exercise price of $6.20 per share with an intrinsic value of $3. In December 2018, the Company’s board of directors adopted an initial offering of the Company’s common stock under the Company’s 2018 Employee Stock Purchase Plan (the “ESPP”). The Company’s ESPP provides for an initial reserve of 150,000 shares and this reserve is automatically increased on January 1 of each year by the lesser of 1% of the outstanding common shares at December 31 of the preceding year or 150,000 shares, subject to reduction at the discretion of the Company’s board of directors. As of March 31, 2021, there were 529,335 shares available for issuance under the ESPP. The initial offering of the ESPP began on December 17, 2018 and ended on December 10, 2019. The annual offerings consist of two stock purchase periods, with the first purchase period ending in June and the second purchase period ending in December. The terms of the ESPP permit employees of the Company to use payroll deductions to purchase stock at a price per share that is at least the lesser of (1) 85% of the fair market value of a share of common stock on the first date of an offering or (2) 85% of the fair market value of a share of common stock on the date of purchase. After the initial offering period ended, subsequent twelve-month offering periods automatically commence over the term of the ESPP on the day that immediately follows the conclusion of the preceding offering, each consisting of two purchase periods approximately six months in duration. In accordance with the June and December stock purchase periods for the ESPP, there were no share issuances in the first three months of 2021 or 2020. The weighted average grant date fair value of share awards in 2021 and 2020 was $2.29 and $2.64, respectively. Employees contributed $80 and $50 via payroll deductions during the three months ended March 31, 2021 and 2020, respectively. The Company recorded an expense of $19 and $21 related to the ESPP in the three-month periods ended March 31, 2021 and 2020, respectively. As of March 31, 2021 and December 31, 2020, the accompanying condensed balance sheets include $99 and $18, respectively, in accrued liabilities for remaining employee ESPP contributions. 16 Eton Pharmaceuticals, Inc. Notes to Condensed Financial Statements ( in thousands, except share and per share amounts) (Unaudited) Note 9 — Related Party Transactions Harrow Harrow was issued 3,500,000 shares of the Company’s common stock at the formation of the Company at the $0.001 par value per share price as the paid-in-capital contribution from Harrow. The Company and Harrow signed licensing agreements for two products developed by Harrow whereby Harrow assigned the product rights to the Company. In July 2018, the Company determined that one of the products was not viable for its portfolio of product opportunities and cancelled the licensing agreement whereby Harrow retains the product rights. On May 6, 2019, the Company entered into an Asset Purchase Agreement (the “CT-100 Asset Purchase Agreement”) with Harrow. Pursuant to the CT-100 Asset Purchase Agreement, the Company sold all of its right, title and interest in CT-100 to Harrow, including any such product that incorporates or utilizes its intellectual property rights (a “Product” or, collectively, “Products”). Pursuant to the CT-100 Asset Purchase Agreement, Harrow will make certain payments to the Company upon the achievement of certain development and commercial milestones. In addition, Harrow is required to pay the Company a royalty in the low-single digit percentage range worldwide on a country-by-country basis on net sales for a period of the longer of 15 years from the date of the first commercial sale of a product in a particular country or the time that a valid intellectual property claim on such Product remains in force in the applicable country. The CT-100 Asset Purchase Agreement also contains customary representations, warranties, covenants and indemnities by the parties. As part of the early start-up for the Company’s pharmaceutical business in 2017, key executives at Harrow received a total of 1,500,000 shares of restricted common stock in the Company for consulting services, and certain Harrow managers also received stock options to purchase a total of 130,000 shares of common stock from the Company (20,000 of these options were forfeited in 2018). The restricted stock and stock options vested in full on April 30, 2018. Additionally, the Chief Executive Officer of Harrow was a member of the Company’s board of directors until March 17, 2021 when he retired from service with the board. 17 Eton Pharmaceuticals, Inc. Notes to Condensed Financial Statements ( in thousands, except share and per share amounts) (Unaudited) Note 9 — Related Party Transactions (continued) Chief Executive Officer The CEO has a partial interest in a company that the Company has partnered with for its EM-100 product as described below. The Company acquired the exclusive rights to sell the EM-100 product in the United States pursuant to a sales and marketing agreement (the “Eyemax Agreement”) dated August 11, 2017 between the Company and Eyemax LLC (“Eyemax”), an entity affiliated with the Company’s CEO. The Company also held a right of first refusal to obtain the exclusive license rights for geographic areas outside of the United States. Pursuant to the Eyemax Agreement, the Company was responsible for all costs of testing and FDA approval of the product, other than the FDA filing fee which was paid by Eyemax. The Company was also to be responsible for commercializing the product in the United States at its expense. The Company paid Eyemax $250 upon execution of the Eyemax Agreement, which was recorded as a component of R&D expense. Under the terms of the original agreement, the Company would pay Eyemax $250 upon FDA approval and $500 upon the first commercial sale of the product and pay Eyemax a royalty of 10% on the net sales of all products. The Eyemax Agreement was for an initial term of 10 years from the date of the Eyemax Agreement, subject to successive two-year renewals unless the Company elected to terminate the Eyemax Agreement. On February 18, 2019, The Company entered into an Amended and Restated Agreement with Eyemax amending the Eyemax Agreement (the “Amended Agreement”). Pursuant to the Amended Agreement, Eyemax sold the Company all of its right, title and interest in EM-100, including any such product that incorporates or utilizes Eyemax’s intellectual property rights. Under the Amended Agreement, the Company assumed certain liabilities of Eyemax under its Exclusive Development & Supply Agreement with Excelvision SAS dated as of July 11, 2013, as amended (the “Excelvision Agreement”), with respect to certain territories and arising during certain time periods. Pursuant to the Amended Agreement, the Company was obligated to pay Eyemax two milestone payments: (i) one milestone payment for $250 upon regulatory approval in the territory by the FDA of the first single agent product which was paid in October 2020 and (ii) one milestone payment for $500 following the first commercial sale of the first single agent product in the territory which was paid in February 2021. Following payment of the milestones, the Company is entitled to retain all of the non-royalty transaction revenues and royalties up to $2,000 (the “Recovery Amount”). After the Company has retained the full Recovery Amount, it is entitled to retain half of all royalty and non-royalty transaction revenue. The Amended Agreement also contains customary representations, warranties, covenants and indemnities by the parties. The EM-100 asset and its associated product rights were sold to Bausch Health on February 18, 2019 and future potential royalties of twelve percent on Bausch Health sales of EM-100, which was approved by the FDA in September 2020, will be split between Eyemax and the Company. The royalty from Bausch Health is subject to reduction if a competitive product with the same active pharmaceutical ingredient is launched in the U.S. or if the EM-100 U.S market share falls below a specified target percentage. There were no amounts due to Eyemax under the terms of the Amended Agreement as of March 31, 2021 or December 31, 2020. 18 Eton Pharmaceuticals, Inc.

The Company is not aware of any pending or threatened litigation matters at this time that may have a material impact on the operations of the Company. License and product development agreements The Company has entered into various agreements in addition to those discussed above which are described below. The Company acquired the exclusive rights to sell the Cysteine injection product in the United States pursuant to a sales and marketing agreement dated November 17, 2017 with an unaffiliated third party (the “Sales Agreement”). Pursuant to the Sales Agreement, the licensor is responsible for obtaining FDA approval, at its expense, and the Company is responsible for commercializing the product in the United States at its expense. The Company was to pay the third party 50% of the net profit from the sale of the product, however, in February 2020, it executed an amendment to the Sales and Marketing Agreement. Under the revised terms, the Company will be responsible for paragraph IV related litigation and will be entitled to 62.5% of product profit. The initial term is for the first 10 years following the first commercial sale of the product. On February 8, 2019, the Company entered into an Exclusive Licensing and Supply Agreement (the “ET-202 License Agreement”) with Sintetica SA (“Sintetica”) for marketing rights in the United States to Biorphen® which is used for the treatment of clinically important hypotension resulting primarily from vasodilation in the setting of anesthesia. The product was submitted to the FDA for review and subsequently received FDA approval on October 21, 2019. Pursuant to the terms of the ET-202 License Agreement, the Company is responsible for marketing activities and Sintetica is responsible for development, manufacturing, and the regulatory activities related to approval. The Company paid Sintetica a licensing payment of $2,000 upon execution of the ET-202 License Agreement and $750 upon the commencement of commercial product shipments. Sintetica will supply Biorphen to the Company at its direct costs and the Company will retain 5% of net sales as a marketing fee. Sintetica is entitled to receive the first $500 of product profits. All additional profit will be split 50% to the Company and 50% to Sintetica. The ET-202 License Agreement has a ten-year term from the first commercial sale of Biorphen which occurred in November 2019. On February 8, 2019, the Company also entered into an Exclusive Licensing and Supply Agreement (the “ET-203 License Agreement”) with Sintetica for marketing rights in the United States to ephedrine, an injectable product candidate for use in the hospital setting. Pursuant to the terms of the ET-203 License Agreement, the Company will be responsible for marketing activities and Sintetica will be responsible for development, manufacturing, and regulatory activities related to obtaining regulatory approval. The Company paid Sintetica a licensing payment of $1,000 upon execution of the ET-203 License Agreement which was refunded to Eton in early 2020 due to the FDA not accepting the ET-203 file submission by Sintetica. The refund was reflected as a component of prepaid and other current assets on the Company’s balance sheet at December 31, 2019. The ET-203 product was successfully resubmitted in late 2020 and the Company will pay a $600 milestone fee and will also pay $750 upon FDA approval and the commercial sale of the product candidate. Upon approval, Sintetica will supply ET-203 to the Company at its direct costs. The Company will retain 5% of net sales as a marketing fee. Sintetica will be entitled to receive the first $500 of product profits. All additional profit will be split 50% to the Company and 50% to Sintetica. The ET-203 License Agreement has a ten-year term from first commercial sale of product.

In addition, the Company was required to pay the licensor 35% of the net profit from product sales. The Agreement was for an initial term of 10 years from the date of the first commercial sale of the product. The Company was to retain sole ownership of the NDA after expiration of the Agreement. On June 12, 2019, the Company entered into an Exclusive Licensing and Supply Agreement (the “ET-105 License Agreement”) with Aucta Pharmaceuticals, Inc. (“Aucta”) for marketing rights in the United States to Lamotrigine, an oral suspension product candidate for use as an adjunct therapy for partial seizures, primary generalized tonic-clonic seizures, and generalized seizures of Lennox-Gastaut syndrome in patients two years of age and older. Pursuant to the terms of the ET-105 License Agreement, the Company was to be responsible for marketing activities and Aucta will be responsible for development, manufacturing, and regulatory activities related to obtaining regulatory approval. The Company paid Aucta a licensing payment of $2,000 in August 2019 upon receiving an acceptance for review letter from the FDA and will pay $2,450 upon FDA approval and commercial sales of the product candidate and another $1,000 upon issuance of an Orange-book listed patent. If Aucta successfully completes a Lamotrigine product line extension product, Eton will pay $1,500 upon FDA acceptance of the product filing and $1,950 upon FDA approval and commercial sales of the extension product candidate. Aucta will receive a low double-digit royalty on net sales and will be entitled to receive milestone payments of up to $18,000 based on commercial success of the product, including: ● $1,000 when net sales exceed $10 million in a calendar year ● $2,000 when net sales exceed $20 million in a calendar year ● $5,000 when net sales exceed $50 million in a calendar year ● $10,000 when net sales exceed $100 million in a calendar year Eton will remain responsible for certain licensing fee obligations owed to its development partners and Azurity will assume royalty or profit share obligations owed to development partners. On March 27, 2020, the Company entered into an Exclusive Licensing and Supply Agreement (the “Alkindi License Agreement”) with Diurnal for marketing Alkindi Sprinkle in the United States. Alkindi Sprinkle’s New Drug Application (NDA) was approved by the FDA on September 29, 2020 as a replacement therapy for pediatric adrenal insufficiency (AI), including congenital adrenal hyperplasia (CAH) in patients from birth to less than 17 years of age. For the initial licensing milestone fee, the Company paid Diurnal $3,500 in cash and issued 379,474 shares of its common stock to Diurnal which were valued at $1,264 based on the Company’s closing stock price of $3.33 on March 26, 2020. The total amount of $4,764 was recorded as a component of research and development expense in the Company’s statement of operations for the three months ended March 31, 2020. The Company will also pay Diurnal $2,500 if the product obtains orphan drug exclusivity status from the FDA. Indemnification As permitted under Delaware law and in accordance with the Company’s Amended and Restated Bylaws, the Company is required to indemnify its officers and directors for certain events or occurrences while the officer or director is or was serving in such capacity. The Company is also party to indemnification agreements with its directors and officers. The Company believes the fair value of the indemnification rights and agreements is minimal. Accordingly, the Company has not recorded any liabilities for these indemnification rights and agreements as of March 31, 2021 or December 31, 2020. 21 Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations You should read the following discussion and analysis of our financial condition and results of operations in conjunction with (i) our unaudited interim condensed financial statements and the related notes thereto included elsewhere in this Quarterly Report on Form 10-Q and (ii) our audited financial statements and notes thereto and management’s discussion and analysis of financial condition and results of operations Included in our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the Securities and Exchange Commission (the “SEC”) on March 16, 2021 (the “2020 10-K”). Forward-Looking Statements This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934 (the “Exchange Act”), including, without limitation, statements regarding our expectations, beliefs, intentions or future strategies that are signified by the words “expect,” “anticipate,” “intend,” “believe,” “may,” “plan”, “seek” or similar language. All forward-looking statements included in this document are based on information available to us on the date hereof, and we assume no obligation to update any such forward-looking statements. Our business and financial performance are subject to substantial risks and uncertainties. Actual results could differ materially from those projected in the forward-looking statements. In evaluating our business, you should carefully consider other matters set forth in our SEC filings including the Risk Factors set forth in Part I, Item 1A of our 2020 10-K. Overview We are a specialty pharmaceutical company focused on developing and commercializing innovative pharmaceutical products and we have particularly targeted hospital injectable and pediatric rare disease products. We seek to improve the formula, delivery system, or safety of existing molecules in order to address unmet patient needs. We pursue what we perceive to be low-risk candidates where existing published literature, historical clinical trials, or physician usage has established safety and/or efficacy of the molecule, thereby reducing the incremental clinical burden required for us to bring the product to patients. In October 2019, we received FDA approval for Biorphen® which we are marketing in the United States. Biorphen (phenylephrine HCl injection) is an alpha-1 adrenergic receptor agonist indicated for the treatment of clinically important hypotension resulting primarily from vasodilation in the setting of anesthesia. In September 2020, the FDA approved our Alkindi Sprinkle product as a replacement therapy for pediatric adrenal insufficiency (AI), including congenital adrenal hyperplasia (CAH) in patients from birth to less than 17 years of age. In addition, the FDA approved EM-100, an eye allergy product which we sold to Bausch Health whereby we will receive royalties on sales of EM-100 which was launched in late January 2021. We received a $1,500 milestone payment from Bausch in accordance with the product launch for EM-100. In February 2021, we sold three pediatric neurology products we had under development to Azurity Pharmaceuticals (“Azurity”) and received $9,500 in proceeds. We anticipate additional revenues from Azurity based on various product-related milestones including the commercial launch for these products which are currently under review with the FDA. We have established a diversified pipeline of product candidates in various stages of development, including multiple candidates that have been submitted to the FDA for review. Our product candidates are primarily focused on two core areas: hospital-based products and pediatric oral liquid products. We believe these candidates can address situations where patient needs are not being met by current FDA-approved products. Results of Operations We had total revenue of $11,897 for the three-month period ended March 31, 2021 which reflected the Azurity and Bausch milestones revenue discussed above plus product sales and royalty revenues which generated a total gross profit of $10,307 for the period. For the three-month period ended March 31, 2020 we had $99 of sales from our Biorphen product at a negative gross profit of $3. Research and Development Expenses For the three-month periods ended March 31, 2021 and 2020, we incurred $886 and $6,268 of research and development expenses (“R&D”), respectively. The 2021 period reflected a reduced overall R&D activity while the 2020 period included $4,764 in expense for the licensing payments for the U.S. rights to Alkindi® Sprinkle. The full comparative three-month detail of our R&D expense is listed in the table below and reflects an overall $5,382 lower expense level in 2021 as we are focusing on commercial development of our Alkindi Sprinkle and Biorphen products at this time. 22 Set forth in the table below is our research and development spending for our current product candidates and general product development expenses for the three-month periods ended March 31, 2021 and 2020. We do not track internal costs by product for our employees and laboratory expenses and they are listed as indirect expenses in the table below. In March 2021, we decided to discontinue our laboratory product testing operations and anticipate completing a sale of our laboratory equipment in May 2021. Three months ended March 31, 2021 Three months ended March 31, 2020 Alkindi Sprinkle $ — $ 4,764 Cysteine 99 401 Dehydrated Alcohol 157 — Biorphen 61 65 Other products 35 163 Indirect expenses 534 875 TOTAL $ 886 $ 6,268 General and Administrative Expenses General and administrative (“G&A”) expenses consist primarily of employee compensation expenses, legal and professional fees, product marketing expenses, distribution expenses, business insurance, travel expenses and general office expenses. For the three-month periods ended March 31, 2021 and 2020, we incurred $4,058 and $2,610, respectively, of G&A expenses. The $1,448 increase in G&A expense was mainly due to $573 in increased compensation expenses and $969 in higher product marketing/distribution expenses mainly related to Alkindi Sprinkle commercialization. This was partially offset by decreased legal expenses mainly due to less activity associated with our Paragraph IV patent challenge related to L-Cysteine. Interest and other expense, net In comparing the three-month periods ended March 31, 2021 and 2020, net interest/other expense increased by $79 primarily as a result of higher interest expense associated with increased borrowings under our SWK Credit agreement. We realized net income of $5,116 for the three months ended March 31, 2021 and incurred a net loss of $9,049 for the three-month period ended March 31, 2020 due to the factors discussed above. Cash Flows The following table sets forth a summary of our cash flows for the three-month periods ended March 31, 2021 and 2020: Three months ended March 31, 2021 Three months ended March 31, 2020 Net cash provided by (used in) operating activities $ 3,715 $ (7,217 ) Cash used in investing activities — (4 ) Cash flows from financing activities 103 7,490 Change in cash and cash equivalents $ 3,818 $ 269 The increase in cash provided by (used in) operating activities was mainly a result of the net income in the 2021 period partially offset by changes in working capital as compared to the net loss in the 2020 period. The 2020 financing activity was primarily the result of the sales of our common stock in March 2020. 23 Critical Accounting Policies Our condensed financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of our condensed financial statements and related disclosures requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, costs and expenses in our condensed financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions. While our significant accounting policies are described in more detail in Note 3 to our financial statements included herein, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of our financial statements. Revenue Recognition We account for contracts with our customers in accordance with Accounting Standards Codification (“ASC”) 606 — Revenue from Contracts with Customers. ASC 606 applies to all contracts with customers, except for contracts that are within the scope of other standards. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to 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, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. At contract inception, once the contract is determined to be within the scope of ASC 606, we assess the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. We assess whether these options provide a material right to the customer and, if so, they are considered performance obligations. The exercise of a material right is accounted for as a contract modification for accounting purposes. We recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) each performance obligation is satisfied at a point in time or over time, and if over time this is based on the use of an output or input method. Any amounts received prior to revenue recognition will be recorded as deferred revenue. Amounts expected to be recognized as revenue within the twelve months following the balance sheet date will be classified as current portion of deferred revenue in our balance sheets. Amounts not expected to be recognized as revenue within the twelve months following the balance sheet date are classified as long-term deferred revenue, net of current portion. Milestone Payments – If a commercial contract arrangement includes development and regulatory milestone payments, we will evaluate whether the milestone conditions have been achieved and if it is probable that a significant revenue reversal would not occur before recognizing the associated revenue. Milestone payments that are not within our control or the licensee’s control, such as regulatory approvals, are generally not considered probable of being achieved until those approvals are received. Royalties – For arrangements that include sales-based royalties, including milestone payments based on a level of sales, which are the result of a customer-vendor relationship and for which the license is deemed to be the predominant item to which the royalties relate, we will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied or partially satisfied. Significant Financing Component – In determining the transaction price, we will adjust consideration for the effects of the time value of money if the expected period between payment by the licensees and the transfer of the promised goods or services to the licensees will be more than one year. 24 We sell Biorphen in the U.S. to wholesale pharmaceutical distributors, who then sell the product to hospitals and other end-user customers. Sales to wholesalers are made pursuant to purchase orders subject to the terms of a master agreement, and delivery of individual shipments of Biorphen represent performance obligations under each purchase order. We use a third-party logistics (“3PL”) vendor to process and fulfill orders and have concluded it is the principal in the sales to wholesalers because it controls access to the 3PL vendor services rendered and directs the 3PL vendor activities. We have no significant obligations to wholesalers to generate pull-through sales. In addition, we sell our Alkindi Sprinkle product to one pharmacy distributor customer which provides order fulfillment and inventory storage/distribution services. Selling prices initially billed to wholesalers are subject to discounts for prompt payment and subsequent chargebacks when the wholesalers sell Biorphen at negotiated discounted prices to members of certain group purchasing organizations (“GPOs”) and government programs. In addition, we pay fees to wholesalers for their distribution services, inventory reporting and chargeback processing. We pay GPOs fees for administrative services and for access to GPO members and concluded the benefits received in exchange for these fees are not distinct from our sales of Biorphen, and accordingly we apply these amounts to reduce revenues. Wholesalers also have rights to return unsold product nearing or past the expiration date. Because of the shelf life of Biorphen and our lengthy return period, there may be a significant period of time between when the product is shipped and when we issue credits on returned product. For our Alkindi Sprinkle product, we bill at the initial product list prices which are subject to offsets for patient co-pay assistance and potential state Medicaid reimbursements which are recorded as a reduction of net revenues at the date of sale/shipment. We estimate the transaction price when we receive each purchase order, taking into account the expected reductions of the selling price initially billed to the wholesaler arising from all of the above factors. We have developed estimates for future returns and chargebacks of Biorphen and the impact of the other discounts and fees we pay. Our sales of Alkindi Sprinkle to our distributor are not subject to returns. When estimating these adjustments to the transaction price, we reduce it sufficiently to be able to assert that it is probable that there will be no significant reversal of revenue when the ultimate adjustment amounts are known. We recognize revenue from Biorphen product sales and related cost of sales upon product delivery to the wholesaler location. At that time, the wholesalers take control of the product as they take title, bear the risk of loss of ownership, and have an enforceable obligation to pay us. They also have the ability to direct sales of product to their customers on terms and at prices they negotiate. Although wholesalers have product return rights, we do not believe they have a significant incentive to return the product to us. We store our Alkindi Sprinkle inventory at our pharmacy distributor customer location and sales are recorded when stock is pulled and shipped to fulfill specific patient orders. Upon recognition of revenue from product sales, the estimated amounts of credit for product returns, chargebacks, distribution fees, prompt payment discounts, state Medicaid and GPO fees are included in sales reserves, accrued liabilities and net of accounts receivable. We monitor actual product returns, chargebacks, discounts and fees subsequent to the sale. If these amounts end up differing from our estimates, we will make adjustments to these allowances, which are applied to increase or reduce product sales revenue and earnings in the period of adjustment. Stock-Based Compensation We account for stock-based compensation under the provisions of Accounting Standards Codification (“ASC”) – 718 Compensation – Stock Compensation. The guidance under ASC 718 requires companies to estimate the fair value of the stock-based compensation awards on the date of grant and record expense over the related service periods, which are generally the vesting period of the equity awards. Compensation expense is recognized over the period during which services are rendered by consultants and non-employees until completed. At the end of each financial reporting period prior to completion of the service, the fair value of these awards is remeasured using the then-current fair value of our common stock and updated assumption inputs in the Black-Scholes option-pricing model (“BSM”). We estimate the fair value of stock-based option awards to our using the BSM. The BSM requires the input of subjective assumptions, including the expected stock price volatility, the calculation of expected term, forfeitures and the fair value of the underlying common stock on the date of grant, among other inputs. The risk-free interest rate was determined from the implied yields for zero-coupon U.S. government issues with a remaining term approximating the expected life of the options or warrants. Dividends on common stock are assumed to be zero for the BSM valuation of the stock options. The expected term of stock options granted is based on vesting periods and the contractual life of the options. Expected volatilities are based on comparable companies’ historical volatility along with a limited weighting included for our own volatility subsequent to our IPO, which we believe represents the most accurate basis for estimating expected future volatility under the current conditions. We account for forfeitures as they occur. 25 Prior to our initial public offering in November 2018, the fair value of the shares of common stock underlying our stock-based awards was determined by our board of directors, with input from management. Because there had been no public market for our common stock prior to the IPO, our board of directors had determined the fair value of the common stock on the grant-date of the stock-based award by considering a number of objective and subjective factors, including enterprise valuations of our common stock performed by an unrelated third-party specialist, valuations of comparable companies, sales of our convertible preferred stock to unrelated third parties, operating and financial performance, the lack of liquidity of our capital stock, and general and industry-specific economic outlook. Following our IPO, we use the closing stock price on the date of grant for the fair value of the common stock. Research and Development Expenses R&D expenses include both internal R&D activities and external contracted services. Internal R&D activity expenses include salaries, benefits and stock-based compensation and other costs to support our R&D operations. External contracted services include product development efforts including certain product licensor milestone payments, clinical trial activities, manufacturing and control-related activities and regulatory costs. R&D expenses are charged to operations as incurred. We review and accrue R&D expenses based on services performed and rely upon estimates of those costs applicable to the stage of completion of each project. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period. Actual results could differ from our estimates. Upfront payments and milestone payments made for the licensing of technology for products that are not yet approved by the FDA are expensed as R&D in the period in which they are incurred. Nonrefundable advance payments for goods or services to be received in the future for use in R&D activities are recorded as prepaid expenses and are expensed as the related goods are delivered or the services are performed. Off Balance Sheet Transactions We do not have any off-balance sheet transactions. 26 JOBS Act Transition Period In April 2012, the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), was enacted. Section 107 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this extended transition period and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies. We are in the process of evaluating the benefits of relying on other exemptions and reduced reporting requirements under the JOBS Act. Subject to certain conditions, as an emerging growth company, we may rely on certain of these exemptions, including without limitation, (i) providing an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act and (ii) complying with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, known as the auditor discussion and analysis. We will remain an emerging growth company until the earlier to occur of (1) the last day of the fiscal year (a) December 31, 2023, which is the end of the fiscal year following the fifth anniversary of the completion of our IPO, (b) in which we have total annual gross revenues of at least $1.07 billion or (c) in which we are deemed to be a “large accelerated filer” under the rules of the SEC, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period. Item 3. Quantitative and Qualitative Disclosures About Market Risk The primary objective of our investment activities is to preserve capital. We do not utilize hedging contracts or similar instruments. We are exposed to certain market risks relating primarily to interest rate risk on our cash and cash equivalents invested during the period and risks relating to the financial viability of the institutions which hold our capital and through which we have invested our funds. We manage such risks by investing in short-term, liquid, highly-rated instruments. As of March 31, 2021, all of our cash is in a non-interest bearing account due to the current low-interest rate environment. We do not currently have exposure to foreign currency risk. 27 Item 4. Controls and Procedures Disclosure Controls and Procedures We maintain “disclosure controls and procedures,” as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, that are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, to allow timely decisions regarding required disclosure. The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. With respect to the three-month period ended March 31, 2021, under the supervision and with the participation of our management, we conducted an evaluation of the effectiveness of the design and operations of our disclosure controls and procedures. Based upon this evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures are effective. Management does not expect that our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control systems are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in a cost-effective control system, no evaluation of internal control over financial reporting can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been or will be detected. Changes in Internal Control over Financial Reporting There has not been any change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the period ended March 31, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 28 PART II. OTHER INFORMATION Item 1. Legal Proceedings None. Item 1A. Risk Factors We operate in a dynamic and rapidly changing environment that involves numerous risks and uncertainties. Certain factors may have a material adverse effect on our business, financial condition, and results of operations, and you should carefully consider them. Other events that we do not currently anticipate or that we currently deem immaterial may also affect our results of operations and financial condition. You should carefully consider the factors discussed in Part I, Item 1A. “Risk Factors” in our 2020 10-K, which could materially affect our business, financial condition, cash flows or future results. The risk factors described in our 2020 10-K, which was filed with the SEC on March 16, 2021, are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition, or future results. 29 Item 2.
