In November 2019, the Company entered into a credit agreement and received net proceeds of $4,750and 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 aan innovative specialty pharmaceutical company focused on developing, acquiring, and commercializing ~~innovative products. Eton is primarily focused on hospital injectable and pediatric~~treatments for rare ~~disease products.~~diseases. 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~~receives 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. One of the three products ~~which~~was approved by the FDA in November 2021 and two are currently under review with the FDA. In June 2021, the Company’s Rezipres product was approved by the FDA and is expected to launch in the coming months. In October 2021, the Company acquired the rights to an FDA-approved generic carglumic acid product indicated for the treatment of hyperammonemia due to N-acetylglutamate Synthase (NAGS) deficiency and it expects to launch this product late in 2021. The Company has three additional product candidates under development, two of which have been submitted to the FDA.

Note 2 — Liquidity Considerations

In During the first ~~six~~nine months of 2021, the Company generated net cash provided by operating activities of $~~3,346~~396 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. Prior to 2021, the Company had generated limited revenues and had incurred negative cash flows from operating activities since its inception in 2017.

The Company currently believes its existing cash and cash equivalents of $~~25,802~~22,709 as of ~~June~~September 30, 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 (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 ~~June~~September 30, 2021 and the results of its operations and its cash flows for the periods ended ~~June~~September 30, 2021 and 2020. The financial data and other information disclosed in these notes related to the three and ~~six-month~~nine-month periods ended ~~June~~September 30, 2021 and 2020 are also unaudited. The results for the ~~six-month~~nine-month period ended ~~June~~September 30, 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 atas of 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.~~bills or high-grade short-term money market accounts. From time to time, amounts deposited with its bank exceed federally insured ~~limits. The~~limits and 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 $8591 and $71 as of ~~June~~September 30, 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. During the three-month period ended September 30, 2021, the Company recorded a provision of $432 for excess quantities of its Biorphen product that are approaching expiration. Inventories at ~~June~~September 30, 2021 and December 31, 2020 consist solely of purchased finished goods. At ~~both June~~September 30, 2021 and December 31, 2020, inventories are shown net of a slow-moving reserve for its Biorphen product of $1,414 and $623, respectively, due to the risk of expiry before this entire stock of inventories is sold.

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 completed a sale of the lab equipment in May 2021 at a price of $700which was $181in excess of the book value for these assets. Accordingly, the $519net book value of these assets was removed from the property and equipment accounts and the $181gain is reflected in the Company’s statements of operations for the ~~three and six-month periods~~nine-month period ended ~~June~~September 30, 2021. In conjunction with the closing of its laboratory operation, the Company scrapped various furniture and equipment which had a net book value of $31which has been included in research and development expense in the statements of operations.

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 $750payment 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 $~~250~~ 287of accumulated amortization as of ~~June~~September 30, 2021. The Company recorded $37 and $75112 of amortization expense for the three and ~~six~~nine months ended ~~June~~September 30, 2021, respectively. The Company will record amortization expense of $150 per year for this intangible asset for 2021 through 2023 and then $125in 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. NaN 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.

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.

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 ~~June~~September 30, 2021 reflected $~~2,500~~ 734~~of licensing milestone fees, $493~~ in product sales and $74 41in royalty revenue. Revenues for the ~~six~~nine months ended ~~June~~September 30, 2021 reflected $14,000of licensing milestone fees, $~~747~~ 1,481in product sales and $~~217~~ 258in royalty revenue. Revenues for the three and ~~six~~nine months ended ~~June~~September 30, 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, write-downs for excess/obsolete inventory, 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.

Income (Loss) Per Share

Basic net ~~income (loss)~~loss per common share is computed by dividing net ~~income (loss) attributable to common stockholders~~loss for the period by the weighted average number of common shares outstanding during the period. Diluted net ~~income (loss)~~loss per share is computed by dividing the net ~~income (loss) attributable to common stockholders~~loss for the period by the weighted average number of common and common equivalent shares, such as unvested restricted stock awards (“RSA”), restricted stock units (“RSU’”), 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 RSUs, and warrants at ~~June~~September 30, 2021 and 2020 were ~~1,352,879~~ 4,279,400and 3,308,152, respectively, and are excluded ~~1,624,598~~ ~~shares that were anti-dilutive (see Note 9).~~from the calculation of diluted net loss per share because the effect is anti-dilutive. Included in the basic and diluted net ~~income (loss)~~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).~~director.

Basic weighted average shares for the three and ~~six~~nine months ended ~~June~~September 30, 2021 include 600,000 vested warrants to purchase common shares. As the shares underlying these warrants can be purchased for little to no consideration ($0.01 per share exercise price), they are included in the computation of basic earnings per share.

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.

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 12) 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 an additional $2,000 and the ability to borrow an additional ~~$3,000~~$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%~~10.0%, subject to a stated LIBOR floor rate of 2.0%. A 2.0% unused credit limit fee iswas 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.

Note 5 — Long Term Debt (continued)

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 $5,000borrowed in November 2019, the Company issued warrants to SWK to purchase 51,239shares of the Company’s common stock with an exercise price of $5.86per share. The relative fair value of the 51,239 warrants was $226and 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 $5.75per share; ~~seven-year~~ 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~~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.

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 5,000,000shares 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 (as amended in January 2021, the “2018 plan”) which succeeded the 2017 Plan. The Company has granted restricted stock awards (“RSAs”), stock options and RSUs for its common stock under the 2017 Plan and 2018 Plan as detailed in the tables below. There were 481,160shares available for future issuance under the 2018 Plan as of ~~June~~September 30, 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 44%% 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~~(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 are not issued until the individual director retires from service from the Company’s board of directors. In April 2021, 25,000 of these vested RSU shares were issued to a director after his retirement from the Company’s board. 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~~ten-year life, except for options to purchase 50,000shares 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 ~~June~~September 30, 2021 and 2020, the Company’s total stock-based compensation expense was $~~836~~1,009 and $~~714~~724, respectively. Of these amounts, $~~691~~838 and $~~651~~ 647, respectively,was recorded in general and administrative expenses, ~~respectively,~~ and $~~145~~171 and $63 77, respectively, was recorded in research and development ~~expenses, respectively.~~expenses.

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.~~stock at period end.

The assumptions used to calculate the fair value of options granted during the ~~six~~nine months ended ~~June~~September 30, 2021 under the BSM were as follows:

Schedule of Assumptions Used to Calculate Fair Value of Options Granted

Expected dividends	0		%
Expected volatility		80	%
Risk-free interest rate		0.9 - 1.1	%
Expected term		5.3 – 6.3 years
Weighted average fair value	$	5.88

Expected Term — The Company has opted to use the “simplified method” for estimating the expected term of options granted to employees and directors, whereby the expected term equals the arithmetic average of the vesting term and the original contractual term of the option (generally ten years). The expected term of options granted to non-employees equals the contractual life of the options.

Expected Volatility — Due to the Company’s limited operating history and a lack of Company-specific historical and implied volatility data, the Company has based its estimate of expected volatility on the historical volatility of a group of similar companies that are publicly traded. The Company has continued this methodology plus given some limited weighting to its own volatility in the periods subsequent to its November 2018 IPO. The historical volatility data was computed using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term of the stock-based awards.

Risk-Free Interest Rate — The risk-free rate assumption is based on the U.S. Treasury instruments with maturities similar to the expected term of the Company’s stock options.

Expected Dividend — The Company has not issued any dividends in its history and does not expect to issue dividends over the life of the options and therefore has estimated the dividend yield to be 0zero.

Fair Value of Common Stock —The Company uses the closing stock price on the date of grant for the fair value of the common stock.

Harrow

Harrow was issued 3,500,000shares of the Company’s common stock at the formation of the Company at the $0.001par value per share price as the paid-in-capital contribution from Harrow. ~~The~~In April 2021, Harrow sold 1,518,000 shares of the Eton common stock it owned in an underwritten public offering. As of September 30, 2021, Harrow owned 1,982,000 shares of Eton’s common shares which represents 8.1% of the Company’s common shares outstanding. In 2017, 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. To date there have not been any sales of the CT-100 product and therefore no earned royalties to the Company for this product.

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.

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 ~~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 ~~June~~September 30, 2021 or December 31, 2020.

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 ~~years~~ following the first commercial sale of the product.

Overview

We are ~~a specialty~~an innovative pharmaceutical company focused on developing, acquiring, and commercializing ~~innovative pharmaceutical~~rare disease products and ~~we have particularly targeted~~certain 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 royaltiesEton owns or receives profit share or royalty payments 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.~~ six FDA-approved products:
● Alkindi Sprinkle® (hydrocortisone granules). Alkindi Sprinkle is a replacement therapy for adrenalcortical insufficiency in pediatric patients. We commercialize the product with our internal sales force focused on pediatric endocrinologists and we estimate that approximately 10,000 children in the United States suffer from adrenal insufficiency. Eton licensed the product from Diurnal Group plc in March 2020 and the product was approved by the FDA in September 2020 and launched in December 2020.
● Carglumic acid tablets. Carglumic acid tablets are a generic version if Carbaglu®, indicated for the treatment of hyperammonemia due to N-acetylglutamate Synthase (NAGS) deficiency. The product was approved by the FDA and licensed by Eton in October 2021. We intend to market the product with our internal sales force and expect the product to be available in the fourth quarter of 2021.
● Biorphen® (phenylephrine hydrochloride injection). Biorphen is the first and only FDA-approved formulation of ready-to-use injectable phenylephrine. The product is used for the treatment of clinically important hypotension resulting primarily from vasodilation in the setting of anesthesia. We commercialize Biorphen under a co-promotion agreement with Xellia Pharmaceuticals. Biorphen was approved by the FDA in October 2019 and sales commenced at the end of 2019.
● Rezipres® (ephedrine hydrochloride injection). Rezipres is a ready-to-use formulation of injectable ephedrine indicated for the treatment of clinically important hypotension occurring in the setting of anesthesia. The product was approved by the FDA in June 2021 and we expect to launch the product in the coming months.
● Alaway Preservative Free® (ketotifen ophthalmic solution). Alaway Preservative Free (formerly known as EM-100) is the first and only FDA-approved preservative-free ophthalmic product for the treat of allergic conjunctivitis. Eton sold the product to Bausch Health and the product was approved by the FDA in September 2020. Bausch Health launched the product early in 2021 and currently commercializes the product via the over-the-counter channel and we receive a royalty on sales of the product.
● Eprontia® (topiramate oral solution). Eprontia is indicated for the treatment of epilepsy and migraine and is the first and only FDA-approved liquid formulation of topiramate. Eton sold the product to Azurity Pharmaceuticals as part of a multi-product transaction in February 2021. The product was approved by the FDA in November 2021 and we will receive royalties on sales of the product and milestone payments when certain launch and commercial success metrics are met. Azurity Pharmaceuticals is expected to launch the product in the fourth quarter of 2021.
In February 2021, we sold three pediatric neurology products we had under development to Azurity Pharmaceuticals (“Azurity”) and ~~have received $12,000 in proceeds. We~~ anticipate additional revenues from Azurity based on various product-related milestones including the commercial launch for these products. Of these three products, ~~which~~Eprontia® (topiramate oral solution) was approved by the FDA in November 2021 and two are currently under review with the FDA. We have three additional product candidates under development, two of which have been submitted to the FDA.

We encountered difficulty in creating significant market pull-through demand for Biorphen in 2020 and 2021 as our in-person sales calls to key personnel at hospitals and surgical centers and introductory product presentation seminars were cancelled as a result of the COVID-19 pandemic. We are working on other promotional efforts to drive further adoption in the market, but we expect that our Biorphen sales and marketing efforts will continue to be adversely affected by the pandemic. In September 2020, we reduced the selling price for Biorphen, which we sell through wholesalers, and recognized a $192 reduction to revenue based on the shelf stock inventory held at our wholesale customers. These same adverse pandemic factors have ~~established a diversified pipeline of product candidates~~adversely impacted our Alkindi Sprinkle sales 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 rare disease products. We believe these candidates can address situations where patient needs are not being met by current FDA-approved products.2021.

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 ~~June~~September 30, 2021 and 2020, we incurred ~~$3,266~~$3,327 and ~~$2,921,~~$3,429, respectively, of G&A expenses.

The ~~$1,793~~$1,691 increase in G&A expense was mainly due to increased product marketing/distribution and selling expenses related to Alkindi Sprinkle commercialization partially offset by a lower level of legal expenses from our initiating a Paragraph IV patent challenge against Exela Pharma Science’s Elcys product (cysteine hydrochloride injection) in 2020.

Interest and other (expense) income

We had slightly higher interest expense ~~level~~ for the three and ~~six-month~~nine-month periods ended ~~June~~September 30, 2021 as compared to the same periods in 2020 due to our borrowing an additional $2,000 under our SWK loan facility in August 2020.

We recognized a $181 gain from the sale of our laboratory equipment in May 2021 and also recognized a $365 gain from the forgiveness of our SBA PPP loan in May 2021.

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.

2827

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.

2928

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.

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 ~~June~~September 30, 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.

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 is 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 ~~six-month~~nine-month period ended ~~June~~September 30, 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 ~~June~~September 30, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 1A. Risk Factors

We operate in a dynamic and rapidly changing environment that involves numerous risks and uncertainties.

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.
