Aldeyra Therapeutics Inc

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

NATURE OF BUSINESS

Aldeyra Therapeutics, Inc. (Aldeyra, Company, we, us and our) was incorporated in the state of Delaware on August 13, 2004 as Neuron Systems, Inc. On December 20, 2012, the Company changed its name to Aldexa Therapeutics, Inc. and, on March 17, 2014, the Company changed its name to Aldeyra Therapeutics, Inc. Aldeyra, together with its wholly-owned subsidiaries, is a clinical-stage biotechnology company devoted to discovering innovative therapies designed to treat immune-mediated and metabolic diseases.

The Company’s principal activities to date include research and development activities along with related general business planning, including raising capital.

BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Consolidation – The accompanying consolidated financial statements were prepared in conformity with accounting principles generally accepted in the United States of America (US GAAP) and pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). The Company’s consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.

Risks and Uncertainties –The ongoing research and development activities will be subject to extensive regulation by numerous governmental authorities in the United States. Prior to marketing in the United States, any drug developed by the Company must undergo rigorous preclinical and clinical testing and an extensive regulatory approval process implemented by the United States Food and Drug Administration (FDA) under the Food, Drug and Cosmetic Act. The Company has limited experience in conducting and managing the preclinical and clinical testing necessary to obtain regulatory approval. There can be no assurance that the Company will not encounter problems in the clinical trials that will cause the Company or the FDA to delay or suspend clinical trials.

The Company’s success will depend in part on its ability to obtain patents and product license rights, maintain trade secrets, and operate without infringing on the property rights of others, both in the United States and other countries. There can be no assurance that patents issued to or licensed by the Company will not be challenged, invalidated, circumvented, or that the rights granted thereunder will provide proprietary protection or competitive advantages to the Company.

Based on the Company's current operating plan, the Company believes that its cash and cash equivalents will be sufficient to fund the Company’s currently projected operating expenses and debt obligations for at least the next 12 months from the date the financial statements are issued. The Company’s assessment of its liquidity and capital resources includes an estimate of the financial impacts of these changes. The Company has based its projections of operating capital requirements on its current operating plan, which includes several assumptions that may prove to be incorrect, and the Company may use all of its available capital resources sooner than the Company expects. The Company will need to secure additional funding in the future, from one or more equity or debt financings, collaborations, or other sources, in order to carry out all of the Company’s planned research and development activities and regulatory activities; commence or continue ongoing commercialization activities, including manufacturing, sales, marketing and distribution, for any of its product candidates for which the Company may receive marketing approval; or conduct any substantial, additional development requirements requested by the FDA. Additional funding may not be available to the Company on acceptable terms, or at all. If the Company is unable to secure additional funding, it could be forced to delay, reduce or eliminate its research and development programs and its reproxalap commercialization efforts.

Curtailment of operations would cause significant delays in the Company’s efforts to develop and introduce its products to market, which is critical to the realization of its business plan and the future operations of the Company.

Use of Estimates – The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions, including fair value estimates for investments, that affect the reported amounts of assets, liabilities, and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting period. The Company evaluates its estimates and assumptions on an ongoing basis. The most significant estimates in the Company’s consolidated financial statements include, but are not limited to, clinical trial accruals, deferred and accrued research and development costs, stock-based compensation, and accounting for income taxes and related valuation allowance. Although these estimates and assumptions are based on the Company’s knowledge of current events and actions it may undertake in the future, actual results may ultimately materially differ from these estimates and assumptions.

Loss Contingencies – The outcome of loss contingencies, legal proceedings, indemnification matters, and claims brought against us is subject to uncertainty. An estimated loss contingency is accrued by a charge to earnings if it is probable that an asset has been impaired or a liability has been incurred and the amount can be reasonably estimated. Determination of whether to accrue a loss requires evaluation of the probability of an unfavorable outcome and the ability to make a reasonable estimate. Changes in these estimates could affect the timing and amount of accrual of loss contingencies and could be material to the financial statements.

Segment Information– Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company views its operations and manages its business inone segment, which is the identification and development of next-generation medicines to improve the lives of patients with immune-mediated and metabolic diseases. See Note 16 for more information on the effects of the adoption of segment reporting.

Cash and Cash Equivalents – The Company classifies all highly liquid investments with original maturities ofthree months or less as cash equivalents and all highly liquid investments with original maturities of greater than three months but less than 12 months as current marketable securities. The Company has a policy of making investments only with commercial institutions that have at least an investment grade credit rating. The Company invests its cash primarily in government securities and obligations and money market funds.

Marketable Securities– Marketable securities consist of government securities and obligations with original maturities of more than 90 days. Debt investments are classified as available-for-sale and are recorded on the balance sheet at fair value with unrealized gains or losses reported as a separate component of other comprehensive income/(loss). Management determines the appropriate classification of its investments at the time of purchase and re-evaluates such determination at each balance sheet date.

At each balance sheet date, the Company assesses available-for-sale securities in an unrealized loss position to determine whether the decline in fair value below amortized cost is a result of credit losses or other factors, whether the Company expects to recover the amortized cost of the security, the Company’s intent to sell and if it is more likely than not that the Company will be required to sell the securities before the recovery of amortized cost. The Company records changes in allowance for expected credit loss in other income (expense). There has been no allowance for expected credit losses recorded during any of the periods presented.

Fair Value of Financial Instruments – Financial instruments including cash equivalents and accounts payable are carried in the financial statements at amounts that approximate their fair value based on the short maturities of those instruments. Marketable securities are carried at fair value and are more fully described in Note 6. The carrying amount of the Company’s credit facility with Hercules Capital, Inc. approximates fair value since the effective interest rate approximates market rates currently available to the Company.

Concentration of Credit Risk – Financial instruments that potentially subject the Company to significant concentrations of credit risk principally consist of cash, cash equivalents and marketable securities, if any. The Company places its cash and cash equivalents and marketable securities with financial institutions which management believes have high credit ratings and may hold some amounts exceeding federally insured limits. As part of its cash and investment management processes, the Company performs periodic evaluations of the credit standing of the financial institutions with whom it maintains deposits.

Intellectual Property – The legal and professional costs incurred by the Company to acquire its patent rights are expensed as incurred and included in general and administrative expenses. At December 31, 2024 and 2023, the Company has determined that these expenses have not met the criteria to be capitalized since the future benefits to be derived from the patents is uncertain. Intellectual property related expenses for the years ended December 31, 2024 and 2023 were $1.0 million and $1.2 million, respectively.

Collaborative Arrangements – The Company analyzes its collaboration arrangements to assess whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities and therefore within the scope of ASC 808, Collaborative Arrangements (ASC 808). The ASC 808 assessment is performed throughout the life of the arrangement based on changes in the responsibilities of all parties in the arrangement. For collaboration arrangements within the scope of ASC 808 that contain units of account, the Company first determines which units of account of the collaboration are more reflective of a vendor-customer relationship and therefore within the scope of ASC 606, Revenue from Contracts with Customers (ASC 606), if any, and which units of may be subject to other specific recognition guidance, if any. For units of account of collaboration arrangements that are accounted for pursuant to ASC 808, and not subject to other specific recognition guidance, an appropriate recognition method is determined and applied consistently, either by analogy to authoritative accounting literature or by applying a reasonable and rational policy election.

For collaboration arrangements that are within the scope of ASC 808, the Company evaluates the income statement classification for presentation of amounts due from or owed to other participants associated with multiple activities in a collaboration arrangement based on the nature of each separate activity. Payments or reimbursements that are the result of a collaborative relationship instead of a customer relationship, such as co-development and co-commercialization activities, are recorded as research and development expense or selling, general and administrative expense, in the event of a payment to the collaborative partner in a period, or a reduction to these expense line items in the event of a reimbursement from the collaboration partner in a period, as appropriate.

Income Taxes – The Company follows the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 740, Income Taxes (ASC 740), in reporting deferred income taxes. ASC 740 requires a company to recognize deferred tax liabilities and assets for expected future income tax consequences of events that have been recognized in the Company’s financial statements. Under the ASC 740 method, deferred tax assets and liabilities are determined based on temporary differences between financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in the years in which the temporary differences are expected to reverse. Valuation allowances are provided if based on the weight of available evidence, it is more likely than not that some or all the deferred tax assets will not be realized.

The Company accounts for uncertain tax positions pursuant to ASC 740 which prescribes a recognition threshold and measurement process for financial statement recognition of uncertain tax positions taken or expected to be taken in a tax return. If the tax position meets the threshold, the benefit to be recognized is measured as the tax benefit having the highest likelihood of being realized upon ultimate settlement with the taxing authority. The Company recognizes interest accrued related to unrecognized tax benefits and penalties in the provision for income taxes. Management is not aware of any uncertain tax positions.

Research and Development Costs – Research and development (R&D) costs are charged to expense as incurred and relate to salaries, employee benefits, stock-based compensation related to employees, consulting services, other operating costs and expenses associated with preclinical and clinical trial activities. Payments made by the Company in advance for research and development services not yet provided and/or for materials not yet received are recorded as deferred research and development expenses. Accrued liabilities are recorded related to those expenses for which vendors have not yet billed us with respect to services provided and/or materials that we have received.

Preclinicaland clinical trial expenses relate to third-party services, subject-related fees at the sites where the Company’s clinical trials are being conducted, laboratory costs, analysis costs, toxicology studies and investigator fees. Costs associated with these expenses are generally payable on the passage of time or when certain milestones are achieved. Expense is recorded during the period incurred or in the period in which a milestone is achieved. In order to ensure that the Company has adequately provided for preclinical and clinical expenses during the proper period, the Company maintains an accrual for these expenses. These accruals are assessed on a quarterly basis and are based on such assumptions as total costs incurred to date, the number of subjects and clinical trial sites and length of the study. Actual results may differ from these estimates and could have a material impact on the Company’s reported results. The Company’s historical accrual estimates have not been materially different from actual costs.

Stock-Based Compensation – Stock-based payments are accounted for in accordance with the provisions of ASC 718, Compensation – Stock Compensation. For options, the fair value of stock-based payments is estimated, on the date of grant, using the Black-Scholes option pricing model. For restricted stock units, fair value is based on the fair value of the underlying stock on the date of grant. The resulting fair value for restricted stock units and options expected to vest is recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the applicable restricted stock units or options. The Company records the effect of forfeitures and cancellations when they occur.

For performance-based awards, at each reporting period we assess the probability that the performance condition(s) will be achieved. We use the accelerated attribution method to expense the awards over the continuous service period based on the probability of achieving the performance conditions. We estimate the continuous service period based on our best estimate of the period over which an award’s vesting condition(s) will be achieved. We review and evaluate these estimates on a quarterly basis.

The Company has cash awards and performance cash settled bonus awards, which are awards that will be settled in cash on their vesting dates (Liability Awards), rather than in equity units. The fair value of Liability Awards is updated at each balance sheet date and changes in the fair value of the vested portions of the Liability Awards are recorded as increases or decreases to compensation expense. The Company recognizes forfeitures as they occur.

Comprehensive Loss– Comprehensive loss is defined as the change in equity during a period from transactions and other events and/or circumstances from non-owner sources. For December 31, 2024, comprehensive loss is equal to the Company’s net loss of$55.9 million and an unrealized gain on marketable securities to net loss of $0.1 million. For December 31, 2023, comprehensive loss is equal to the Company's net loss of$37.5 million and reclassification of losses on marketable securities to net loss of $0.1 million.

Net Loss Per Share– Basic earnings per share is calculated by dividing net loss allocable to common stockholders by the weighted average number of common stock outstanding during the period, excluding the effects of any potentially dilutive instruments.

Diluted net loss per share is computed using the more dilutive of (a) the two-class method, or (b) treasury stock method, as applicable, to the potentially dilutive instruments. The weighted-average number of common shares outstanding gives effect to all potentially dilutive common equivalent shares, including outstanding stock options and restricted stock units, warrants, if any, and nonvested shares.

Recent Accounting Pronouncements – In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (ASU 2023-07). ASU 2023-07 is intended to improve reportable segment disclosure requirements, primarily through additional disclosures about significant segment expenses, including for single reportable segment entities. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statements. The Company adopted ASU 2023-07, which did not have a material impact on the Company's consolidated financial statements. See Note 16 for more information on the effects of the adoption of ASU 2023-07.

In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures (ASU 2023-09). ASU 2023-09 requires more detailed income tax disclosures. The guidance requires entities to disclose disaggregated information about their effective tax rate reconciliation as well as expanded information on income taxes paid by jurisdiction. The disclosure requirements will be applied on a prospective basis, with the option to apply them retrospectively. The standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the disclosure requirements related to the new standard.

In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses (ASU 2024-03). ASU 2024-03 requires public business entities to disclose in the notes to the financial statements, among other things, specific information about certain costs and expenses including purchases of inventory; employee compensation; and depreciation, amortization and depletion expenses for each caption on the income statement where such expenses are included. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted, and the amendments may be applied prospectively to reporting periods after the effective date or retrospectively to all periods presented in the financial statements. The Company is evaluating the disclosure requirements related to the new standard.

HELIO VISION ACQUISITION

On January 28, 2019 (Closing Date), the Company acquired Helio Vision, Inc. (Helio) and thereby obtained rights to develop ADX‑2191 for the treatment of proliferative vitreoretinopathy (the Helio Product Candidate) pursuant to an Agreement and Plan of Merger dated as of January 24, 2019 (the Merger Agreement). As a result of the acquisition, the Company issued an aggregate of 1,407,006 shares of common stock to the former securityholders and an advisor of Helio, including 246,562 shares issued in January 2021, pursuant to the terms of the acquisition agreement. In addition, the Company, subject to the conditions of the acquisition agreement, was contingently obligated to make additional payments to the former securityholders of Helio as follows: (a) $10.0 million of common stock following approval by the FDA of a new drug application (NDA) for the prevention and/or treatment of proliferative vitreoretinopathy or a substantially similar label prior to the 10th anniversary of the Closing Date; and (b) $2.5 million of common stock following FDA approval of an NDA for an indication (other than proliferative vitreoretinopathy or a substantially similar label) prior to the 12th anniversary of the Closing Date (the shares of common stock issuable pursuant to the preceding clauses (a) and (b) are referred to herein as the Milestone Shares), provided that in no event shall the Company be obligated to issue more than an aggregate of 5,248,885 shares of common stock in connection with the Helio acquisition. During the year ended December 31, 2024, the Company ceased development of the Helio Product Candidate for the treatment of proliferative vitreoretinopathy. As a result, subject to the terms and conditions of the Merger Agreement, the Helio Product Candidate and related intellectual property rights may revert to an entity designated by the representative of the former Helio stockholders. Additionally, in the event of certain change of control or divestitures by the Company, certain former convertible noteholders of Helio will be entitled to a tax gross-up payment in an amount not to exceed $1.0 million in the aggregate.

The Company determined that liability accounting is not required for the Milestone Shares under FASB ASC Topic 480, Distinguishing Liabilities from Equity (ASC 480). The Company also determined that the Milestone Shares meet the scope exception as a derivative under FASB ASC Topic 815, Derivatives and Hedging (ASC 815), from inception of the Milestone Shares through December 31, 2024. Accordingly, the Milestone Shares are evaluated under FASB ASC Topic 450, Contingencies (ASC 450) and the Company will record a liability related to the Milestone Shares if the milestones are achieved, and the obligation to issue the Milestone Shares becomes probable. At such time, the Company will record the cost of the Milestone Shares issued to the Helio founders as a compensation expense and to the other former securityholders of Helio as an in-process research and development expense if there is no alternative future use. No milestones related to the remaining Milestone Shares are considered probable of being achieved as of December 31, 2024.

NET LOSS PER SHARE

For the years ended December 31, 2024 and 2023, diluted weighted-average common shares outstanding is equal to basic weighted-average common shares due to the Company’s net loss position.

The following potentially dilutive securities outstanding have been excluded from the computation of diluted weighted-average shares outstanding, because such securities had an antidilutive impact:

CASH, CASH EQUIVALENTS, AND MARKETABLE SECURITIES

At December 31, 2024, cash, cash equivalents, and marketable securities were comprised of:

(1)

Available for sale debt securities are reported at fair value with unrealized gains and losses reported net of taxes, if material, in other comprehensive loss.

The contractual maturities of all cash equivalents and available for sale securities were less than one year at December 31, 2024.

At December 31, 2023, cash, cash equivalents, and marketable securities were comprised of:

There wereno marketable securities held at December 31, 2023.

FAIR VALUE MEASUREMENTS

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value are performed in a manner to maximize the use of observable inputs and minimize the use of unobservable inputs. ASC 820, Fair

Value Measurements, establishes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following:

Level 1 – Quoted prices in active markets that are accessible at the market date for identical unrestricted assets or liabilities.

Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs for which all significant inputs are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The following table presents information about the Company’s assets measured at fair value at December 31, 2024 and December 31, 2023:

(a)

Money market funds included in cash and cash equivalents in the consolidated balance sheets, are valued at quoted market prices in active markets.

(b)

U.S. government agency securities are recorded at fair market value, which are determined based on the most recent observable inputs for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active or are directly or indirectly observable.

There wereno liabilities measured at fair value at December 31, 2024 or December 31, 2023.

Financial instruments including clinical trial prepayments to contract research organizations and accounts payable are carried in the consolidated financial statements at amounts that approximate their fair value based on the short maturities of those instruments. The carrying amount of the Company’s term loan under the Hercules Credit Facility (as defined in Note 9) approximates market rates currently available to the Company.

PREPAID EXPENSES AND OTHER CURRENT ASSETS

Prepaid expenses and other current assets at December 31, 2024 and 2023 were:

ACCRUED EXPENSES

Accrued expenses at December 31, 2024 and 2023 were:

CREDIT FACILITY

The Company’s current and long-term debt obligation consists of amounts the Company is obligated to repay under its credit facility with Hercules Capital, Inc. (Hercules). In March 2019, the Company entered into a Loan and Security Agreement (Loan and Security Agreement or Hercules Credit Facility) with Hercules and several banks and other financial institutions or entities, from time-to-time parties thereto (collectively, referred to herein as Lender), providing for a term loan of up to $60.0 million, subject to the satisfaction of certain conditions contained therein, that is secured by a lien covering all of the Company’s assets, other than the Company’s intellectual property. The Loan and Security Agreement provided for (i) an initial term loan advance of up to $5.0 million at the Company’s option, which expired unutilized on April 15, 2019; (ii) three additional term loan advances of up to $15.0 million each, at the Company’s option, available to the Company upon the occurrence of certain pre-specified funding conditions prior to September 30, 2019 (2019 Tranche), March 31, 2020 (2020 Tranche), and March 31, 2021 (2021 Tranche); and (iii) a final additional term loan advance (Fourth Loan Tranche) of up to $10.0 million prior to December 31, 2021, at the Company’s option, subject to approval by the Lender’s investment committee. The 2019 Tranche was drawn down in full by the Company in September 2019 and the 2020 Tranche and 2021 Tranche expired unutilized prior to the Company satisfying the funding conditions for such tranche. On April 20, 2021, the Company entered into the First Amendment to the Loan and Security Agreement (First Amendment). The First Amendment, among other things, (i) increased the Fourth Loan Tranche from $10.0 million to $20.0 million and extended the deadline for drawing down the Fourth Loan Tranche to July 1, 2022; (ii) lowered the variable per annum rate of interest on borrowings under the Loan and Security Agreement from the greater of (a)9.10% and (b) the prime rate (as reported in the Wall Street Journal or any successor publication thereto) plus 3.10% to the greater of (x) the Prime Rate (as defined therein) plus 3.10% or (y) 8.60%; (iii) extended the expiration of the period in which interest-only payments on borrowings under the Loan and Security Agreement are required from May 1, 2021 to July 1, 2022; and (iv) following the satisfaction of certain conditions, which conditions were satisfied in April 2021, further extended the expiration of the interest-only period and the deadline for drawing down the Fourth Loan Tranche to May 1, 2023. Repayment of the aggregate outstanding principal balance of the term loan, in monthly installments, was to commence upon expiration of the interest-only period and continue through October 1, 2023 (Maturity Date). The First Amendment was determined to be a modification in accordance with FASB ASC Topic 470 Debt, and did not result in extinguishment.

On December 22, 2022, the Company entered into the Second Amendment to the Loan and Security Agreement (Second Amendment), which became effective as of December 31, 2022 (Second Amendment Effective Date). The Second Amendment, among other things, (i) extended the expiration of the period in which interest-only payments on borrowings under the Loan and Security Agreement were to be made from May 1, 2023 to May 1, 2024; (ii)extended the Maturity Date from October 1, 2023 to October 1, 2024; (iii) extended the availability of the Fourth Loan Tranche commitment of $20 million, which remained conditioned on approval by the Lenders’ investment committee, from May 1, 2023 to May 1, 2024; and (iv) amended the Prepayment Charge (as defined therein) to equal 0.75% of the amount prepaid during the 12-month period following the Second Amendment Effective Date, and 0% thereafter. In addition, a supplemental end of term charge of $292,500 (Supplemental End of Term Charge) shall be due on the earlier of (a) the Maturity Date, as amended, or (b) repayment of the aggregate amount of advances under the Loan and Security Agreement. The initial end of term charge of $1,042,500 (End of Term Charge) was paid on October 2, 2023.

On April 29, 2024, the Company entered into the Third Amendment to the Loan and Security Agreement (Third Amendment). The Third Amendment, among other things, extended the expiration of the period in which interest-only payments on borrowings under the Loan and Security Agreement were to be made from May 1, 2024 to October 1, 2024. On May 1, 2024, the Fourth Loan Tranche commitment expired unutilized. The Second and Third Amendments were determined to be modifications in accordance with FASB ASC Topic 470 Debt, and did not result in extinguishment.

On September 30, 2024, the Company entered into the Fourth Amendment to the Loan and Security Agreement (Fourth Amendment). The Fourth Amendment, among other things, (i) extended the expiration of the period in which interest-only payments on borrowings under the Loan and Security Agreement are made from October 1, 2024 to April 1, 2026; (ii) extended the Maturity Date from October 1, 2024 to April 1, 2026; and (iii) amended the term loan interest rate to be the greater of (a) the Prime Rate (as defined in the Loan and Security Agreement) plus 3.10%, or (b)11.10%. In addition, a supplemental end of term charge of $300,000 (Second Supplemental End of Term Charge) shall be due on the earlier of (a) the Maturity Date, as amended, or (b) repayment of the aggregate amount of advances under the Loan and Security Agreement. The Supplemental End of Term Charge of $292,500 was paid on October 1, 2024. The Fourth Amendment was determined to be a modification in accordance with FASB ASC Topic 470 Debt, and did not result in extinguishment.

On October 28, 2024, the Company entered into the Fifth Amendment to the Loan and Security Agreement (Fifth Amendment). The Fifth Amendment introduces, among other things, new definitions to include holding investments in a wholly owned subsidiary structured as a Massachusetts Security Corporation.

In connection with the Hercules Credit Facility, the Company has incurred; a commitment charge of $25,000, transaction costs of $273,186, a fee of $375,000 upon closing, the End of Term Charge, which was paid in October 2023, and the Supplemental End of Term Charge, which was paid in October 2024. In addition, the Company will be required to pay the Second Supplemental End of Term Charge. The fees and transaction costs are amortized to interest expense from 2019 through the Maturity Date using the effective interest method. Using the effective interest method, the End of Term Charge was amortized to interest expense from 2019 through October 2023, the Supplemental End of Term Charge was amortized to interest expense from December 2022 through October 2024, and the Second Supplemental End of Term Charge is amortized to interest expense from September 2024 through the Maturity Date. The effective interest rate was 12.4% at December 31, 2024. At the Company’s option, the Company may elect to prepay all, but not less than all, of the outstanding term loan by paying the entire principal balance and all accrued and unpaid interest thereon, plus all fees and other amounts due under the Loan and Security Agreement as of the date of such prepayment.

As of December 31, 2024, $15 million has been funded under the Loan and Security Agreement and no additional amounts were available to the Company for borrowing.

Long-term debt consisted of the following:

Future principal payments, including the Supplemental End of Term Charge, are as follows for the years ending December 31:

The Loan and Security Agreement also contains certain events of default, representations, warranties and non-financial covenants of the Company. As of December 31, 2024, the Company was in compliance with all covenants of the Hercules Credit Facility in all material respects. In addition, subject to the terms of the Loan and Security Agreement, the Company granted the Lender the right to purchase up to an aggregate of $2.0 million of the Company’s equity securities, or instruments exercisable for or convertible into equity securities, sold to investors in financings upon the same terms and conditions afforded to such other investors.

STOCKHOLDERS’ EQUITY

Common Stock

Each share of common stock is entitled to one vote. The holders of common stock are also entitled to receive dividends whenever funds are legally available and when declared by the board of directors, subject to the prior rights of holders of all classes of stock outstanding. As of December 31, 2024, a total of 7,621,580,3,919,330, and 2,921,164, shares of common stock were reserved for issuance upon (i) the exercise of outstanding stock options, (ii) the issuance of stock awards under the Company’s 2023 Equity Plan, and (iii) the issuance of shares under the 2016 ESPP, respectively.

2024 Jefferies Sales Agreement

In August 2024, the Company entered into an Open Market Sales Agreement SM with Jefferies LLC (Jefferies), as sales agent (the 2024 Jefferies Sales Agreement), under which the Company has the ability to offer and sell, from time to time through Jefferies, shares of common stock providing for aggregate sales proceeds of up to $75.0 million. As of December 31, 2024, no shares of common stock were sold under the 2024 Jefferies Sales Agreement.

INCOME TAXES

No current or deferred tax provision expense has been recorded for federal income taxes as the Company has incurred losses since inception for tax purposes and maintains a full valuation allowance against net deferred tax assets. During 2024, the Company recorded a $1,000 state current tax provision for liability due from the Company's Massachusetts Security Corporation. There is no deferred tax provision expense recorded for state income taxes because the Company has a full valuation allowance against net deferred tax assets. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

The components of the income tax benefit for the years ended December 31, 2024 and 2023, are as follows:

A reconciliation of the federal statutory tax rate of 21% to the Company’s effective income tax rates are as follows:

Significant components of the Company’s deferred tax assets and liabilities at December 31, 2024 and 2023 are as follows:

The change in valuation allowance of$16.6 million from December 31, 2023 to December 31, 2024 was primarily the result of an increase in capitalized R&D expenses, net operating losses, and tax credits.

In assessing the realizability of net deferred taxes in accordance with Accounting Standards Codification (ASC) 740, Income Taxes (ASC 740), the Company considers whether some portion or all the deferred tax assets are more likely than not to be unrealized. Based on the weight of available evidence, primarily the incurrence of net losses since inception, anticipated net losses in the near future, reversals of existing temporary differences, and expiration of various federal and state attributes, the Company does not consider some or all net deferred taxes more likely than not to be realized. Accordingly, a 100% valuation allowance has been applied against net deferred tax assets.

As of December 31, 2024, the Company had federal and state income tax net operating loss (NOL) carryforwards of approximately $272.0 million and $262.9 million, respectively. Federal NOL carryforwards generated through December 31, 2017 and state NOL carryforwards will expire at various dates through 2044. The federal NOL carryforwards generated during the year ended December 31, 2018 and thereafter will carryforward indefinitely. As of December 31, 2024, the Company had federal and state research and development tax credit carryforwards of approximately $12.1 million and $2.8 million, respectively, which will expire at various dates through 2044. Additionally, as of December 31, 2024, the Company had a federal orphan drug tax credit carryforward of approximately $2.4 million which expire at various dates through 2044.

Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-change NOLs and certain other tax assets to offset future taxable income or tax due. In general, an ownership change occurs if the aggregate stock ownership of certain stockholders increases by more than 50 percentage points over such stockholders’ lowest percentage ownership during the testing period (generally three years). Transactions involving the Company’s common stock within the testing period, even those outside the Company’s control such as purchases or sales by investors, could result in an ownership change. A limitation on the Company’s ability to utilize some or all its NOLs or credits could have a material adverse effect on the Company’s results of operations and cash flows. The Company believes, prior to December 31, 2021 that four ownership changes occurred since inception. Management believes that its aggregate Section 382 and 383 limitation (including the additional limitation for recognized "built-in gains") is sufficient so that no current impairment of its pre-ownership change tax attributes is required. Management believes there were no ownership changes from December 31, 2021 through December 31, 2024, based on a review of the Company's equity history during that period. Any future ownership changes, including those resulting from any recent or future financing activities, may cause our existing tax attributes to have additional limitations.

Future changes in federal and state tax laws pertaining to net operating loss carryforwards may also impose limitations or restrictions on claiming such net operating losses. If the net operating loss carryforwards become unavailable to the Company or are fully utilized, the Company's future taxable income will not be shielded from federal and state income taxation, absent certain U.S. federal and state tax credits, and the funds otherwise available for general corporate purposes would be reduced.

On August 16, 2022 President Biden signed into law the Inflation Reduction Act (IRA). From a tax perspective, the IRA provisions includes a new corporate alternative minimum tax (CAMT) of 15% on adjusted financial statement income (AFSI) for corporations with over $1 billion in profits, a new excise tax on corporate stock buybacks, and increased funding for IRS enforcement. A company’s AFSI can be reduced by net operating losses, foreign tax credits, general business credits, and depreciation for property under Section 197. To determine US federal income tax liability, a company will need to compute taxes under both systems — the regular tax system and the CAMT system. The company then will pay the larger amount as its tax liability in any given year. The Company does not expect to fall into the CAMT system. The IRA provisions have no impact on the Company’s financial statements for the period ended December 31, 2024 and 2023.

As of December 31, 2024, the Company is subject to tax in the U.S. (Federal and Massachusetts). The Company is open to examination for the tax years ended December 31, 2023, 2022, and 2021. In addition, any years remain open to the extent that losses or tax credits are available for carryover to future years.

STOCK INCENTIVE PLAN

The Company approved the 2013 Equity Incentive Plan in October 2013, which was amended in June 2016 and June 2018 (the Amended 2013 Plan). The Amended 2013 Plan provided for the granting of stock options, restricted stock units (RSU), stock appreciation rights, and stock units to certain employees, members of the board of directors and consultants of the Company.

In May 2023, the Company's board of directors approved the 2023 Equity Incentive Plan (the 2023 Equity Plan) to replace the Amended 2013 Plan. On June 30, 2023, the Company's stockholders approved the 2023 Equity Plan at the Company's 2023 annual meeting of stockholders. Pursuant to the 2023 Equity Plan, the Company will not make any further grants under the Amended 2013 Plan following June 30, 2023, though awards previously granted under the Amended 2013 Plan will remain outstanding. The 2023 Equity Plan is effective for a period of ten years after June 30, 2023, and a total of 5,450,000 shares of the Company’s common stock, in addition to shares of the Company’s common stock that are subject to awards granted under the Amended 2013 Plan that are outstanding as of such date and that are subsequently forfeited, cancelled, or expire before being exercised or settled in full, are authorized for issuance under the 2023 Equity Plan. As of December 31, 2024, options to purchase 2,313,500 shares of common stock at a weighted average exercise price of $3.97 pershare remained outstanding under the 2023

Equity Plan. As of December 31, 2024, there were 3,919,330 shares of common stock available for grant under the 2023 Equity Plan.

In 2022, the Company granted cash awards under the Management Cash Incentive Plan, as amended (the Management Cash Incentive Plan). The Management Cash Incentive Plan, which was adopted in 2016, provides participants with the opportunity to earn cash incentive awards for the achievement of goals relating to the performance of the Company. The cash awards, which are equal in value to the amount by which the then value of the Company’s common stock on the Nasdaq Capital Market (Nasdaq) exceeds the base values, vest in four annual installments from the date of grant based on continued service and entitle employees to receive a cash payment on the earlier of (i)four years from the date of grant, or (ii) a change of control. As of December 31, 2024, $0.3 million was accrued as compensation expense for vested cash awards. There wasno unrecognized expense as of December 31, 2024.

In 2022, the Company granted performance cash settled bonus awards (CSBUs) under the Management Cash Incentive Plan. As the performance criteria had been met, the awards, which are equal in value to the closing price per share of the Company's common stock on Nasdaq on the payment date, will vest in four annual installments from the date of grant based on continued service, and entitle employees to receive cash payments for each vested CSBU, on the earlier of (i) four years from the date of grant or (ii) a change of control. As of December 31, 2024, $2.9 million was accrued as compensation expense for CSBUs as the Performance Criteria was met in February 2023. There wasno unrecognized expense as of December 31, 2024.

The Company recognizes stock-based compensation expense over the requisite service period. The Company’s share-based awards are accounted for as equity instruments, except for cash awards and CSBUs, which are accounted for as liabilities. The amounts included in the consolidated statements of operations relating to stock-based compensation associated with the two equity incentive plans, cash awards, and CSBUs are as follows:

Stock Options

Terms of stock option agreements, including vesting requirements, are determined by the board of directors or its compensation committee, subject to the provisions of the respective plan from which they were granted. Options granted by the Company typically vest over afour-year period. The options are subject to acceleration of vesting in the event of certain change of control transactions. The options may be granted for a term of up toten years from the date of grant. The exercise price for options granted under the Amended 2013 Plan and the 2023 Equity Plan must be at a price no less than 100% of the fair market value of a common share on the date of grant.

Thetable below summarizes activity relating to stock options under the incentive plans for the year ended December 31, 2024:

(a)

The aggregate intrinsic value in this table was calculated on the positive difference, if any, between the closing price per share of the Company’s common stock on December 31, 2024 of$4.99 and the per share exercise price of the underlying options. The total intrinsic value of stock options exercised was $0.1 million and $2.0 million for the years ended December 31, 2024 and 2023, respectively.

The Company records stock-based compensation related to stock options granted at fair value. During the years ended December 31, 2024 and 2023, the Company used the Black-Scholes option-pricing model to estimate the fair value of stock option grants and to determine the related compensation expense. The assumptions used in calculating the fair value of stock-based payment awards represent management’s best estimates. The weighted-average grant date fair value of options granted was$2.81 and$5.07 for the years ended December 31, 2024 and 2023, respectively. The assumptions used in determining fair value of the employee stock options for the years ended December 31, 2024 and 2023, are as follows:

The dividend yield ofzero is based on the fact that the Company has never paid cash dividends and haveno present intention to pay cash dividends. Expected volatility is estimated using the historical volatility of the Company. The Company has estimated the expected life of its employee stock options using the “simplified” method, whereby, the expected life equals the average of the vesting term and the original contractual term of the option for service-based awards since the Company does not have sufficient historical or implied data of its own. The risk-free interest rates for periods within the expected life of the option are based on the yields of zero-coupon United States Treasury securities.

At December 31, 2024, there is approximately$6.7 million of unrecognized compensation cost relating to stock options outstanding, which the Company expects to recognize over a weighted average period of 2.38 years. Total unrecognized compensation cost will be adjusted for future forfeitures, if necessary.

Restricted Stock Units

Termsof RSUs agreements, including vesting requirements, are determined by the board of directors or its compensation committee, subject to the provisions of the Amended 2013 Plan and the 2023 Equity Plan. RSUs grantedby the Company typically vest over afour year period and are based on the stock share price on the date of grant to estimated fair value. In the event that the employees’ employment with the Company terminates any unvested shares are forfeited and revert to the Company. RSUs are not included in issued and outstanding common stock until the shares are vested and released. The table below summarizes activity relating to RSUs for the year ended December 31, 2024:

There were no RSUs granted during the year ended December 31, 2024. The weighted-average fair value of RSUs granted was $6.76 per share for the year ended December 31, 2023. The total fair value of RSUs vested was $1.7 million and $2.0 million for the years ended December 31, 2024 and 2023, respectively. As of December 31, 2024, the outstanding RSUs had unamortized stock-based compensation expense of$1.9 million with a weighted-average remaining recognition period of 1.63 years and an aggregate intrinsic value of $2.7 million.

Employee Stock Purchase Plan

In March 2016, the Company’s board of directors approved the 2016 Employee Stock Purchase Plan (2016 ESPP), which became effective in June 2016 following the approval of the Company’s stockholders. The 2016 ESPP initially authorized the issuance of up to a total of 414,639 shares of the Company’s common stock to participating employees. The number of shares reserved for issuance under the 2016 ESPP automatically increases on the first business day of each fiscal year, commencing in 2017, by a number equal to the lower of (i)1% of the shares of common stock outstanding on the last business day of the prior fiscal year; or (ii) the number of shares determined by the Company’s board of directors. Unless otherwise determined by the administrator of the 2016 ESPP, two offering periods of six months’ duration will begin each year on January 1 and July 1. Participating employees purchase stock under the 2016 ESPP at a price equal to the lower of 85% of the closing price on the applicable offering commencement date or 85% of the closing price on the applicable offering termination date. The fair value of the purchase rights granted under the 2016 ESPP plan was estimated on the date of grant using the Black-Scholes option-pricing model using assumptions as shown below:

At December 31, 2024, the Company has 2,921,164 shares available for issuance under the 2016 ESPP. The number of shares available for issuance under the 2016 ESPP was increased as of January 2, 2025 by 596,483 shares. A summary of the weighted-average grant-date fair value, shares issued and total stock-based compensation expense recognized related to the 2016 ESPP for the years ended December 31, 2024 and 2023 are as follows:

COMMITMENTS AND CONTINGENCIES

Guarantees and Indemnifications

As permitted under Delaware law, the Company indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was, serving at the Company’s request in such capacity. The term of the indemnification is for the officer’s or director’s lifetime. Through December 31, 2024, the Company had not experienced any losses related to these indemnification obligations andno material claims were outstanding. The Company currently does not expect significant claims related to these indemnification obligations, consequently concluded that the fair value of these obligations is negligible, andno related reserves were established.

In-License Agreements

MEEI Agreement

The Company was developing ADX‑2191 for the treatment of proliferative vitreoretinopathy pursuant to an Exclusive License Agreement with Massachusetts Eye and Ear Infirmary (MEEI), originally entered into in July 2016 between MEEI and Helio Vision, Inc., as amended, (the MEEI Agreement). The Company assumed the MEEI Agreement in connection with the 2019 acquisition of Helio Vision.

Pursuant to the MEEI Agreement, the Company obtained an exclusive worldwide license from MEEI to develop and commercialize ADX‑2191 under certain patents and patent applications, in addition to other licenses to intellectual property (the MEEI Patent Rights). The Company has agreed to use commercially reasonable efforts to develop ADX‑2191, and to meet certain specified effort and achievement benchmarks by certain dates.

In considerationfor the rights licensed under the MEEI Agreement, Helio Vision issued MEEI a number of shares of preferred stock and Helio Vision agreed, during the term of the agreement, to pay non-creditable non-refundable license maintenance fees to MEEI of $15,000 on each of the second and third anniversary of the agreement, $25,000 on each of the fourth and fifth anniversary of the agreement, and $35,000 on the sixth and each subsequent anniversary of the agreement. In addition, Helio Vision was obligated to make future sales-dependent milestone payments to MEEI of up to low seven figures in the aggregate, as well as royalty payments to MEEI at a rate which, as a percentage of net sales, is in the low single digits for products that incorporate or use the MEEI Patent Rights. Helio is also obligated under the MEEI Agreement to pay MEEI a percentage of certain sublicense revenue at a percentage rate that descends from low-double digits to mid-single digits based on the date of the sublicense. Following the Company’s acquisition of Helio Vision, the Company became obligated to make any future payments previously owed by Helio under the MEEI Agreement. There is no additional equity consideration issuable under the MEEI Agreement.

The MEEI Agreement will remain in effect until the expiration date of the last to expire patent licensed under the MEEI Agreement. The Company may terminate the MEEI Agreement with timely written notice to MEEI. MEEI has the right to terminate the MEEI Agreement, subject to certain specified cure periods, in the event of the Company’s insolvency or bankruptcy or if the Company ceases all business operations with respect to licensed products; the Company fails to pay amounts due under the MEEI Agreement; the Company fails to comply with certain due diligence obligations; the Company does not maintain specific levels of insurance; one of the Company's officers is convicted of a felony relating to the manufacture, use, sale or importation of licensed products; or the Company materially breaches any provisions of the MEEI Agreement or in the event of insolvency or bankruptcy.

In the event of an early termination of the MEEI Agreement, all rights licensed and developed by the Company under the MEEI Agreement will revert to MEEI. The Company has agreed to indemnify MEEI for certain claims that may arise under the MEEI Agreement.

On July 31, 2023, a purported stockholder filed a putative class action lawsuit (the Securities Class Action) in the U.S. District Court for the District of Massachusetts, against the Company and certain current and former officers, captioned Juliana Paice v. Aldeyra Therapeutics, Inc., et al. (No. 23-cv-11737). On January 2, 2024, the lead plaintiff filed an amended complaint. The lawsuit alleges violations by the defendants of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and SEC Rule 10b-5. The plaintiff alleges that the defendants made false or misleading statements or failed to disclose certain information concerning (i) the New Drug Application (NDA) for and the prospects of ADX‑2191 for the treatment of primary vitreoretinal lymphoma, and (ii) the NDA for and the prospects of reproxalap for the treatment of dry eye disease. The lawsuit seeks, among other things, compensatory damages on behalf of herself and all persons and entities that purchased or otherwise acquired the Company's securities between January 7, 2021 and October 16, 2023, as well as attorneys’ fees and costs. On March 4, 2024, defendants filed a motion to dismiss the amended complaint, which was fully briefed as of May 20, 2024. Oral argument on the motion to dismiss was heard on July 24, 2024. The Company disputes the plaintiff's claims and intends to vigorously defend the suit. At this time, the Company cannot reasonably predict the outcome or estimate potential losses, if any, that could result from this matter.

In addition, from time to time, the Company is subject to litigation and claims arising in the ordinary course of business but, except as stated above, the Company is not currently a party to any material legal proceedings and the Company is not aware of any pending or threatened legal proceedings against them that the Company believes could have a material adverse effect on the Company's business, operating results, cash flows, or financial condition.

LEASES

The Company currently leases an office used to conduct business. The Company regularly evaluates the renewal options and when they are reasonably certain of exercise, the Company includes the renewal period in its lease term. As the Company’s lease does not provide an implicit rate, the Company, in determining the present value of the lease payments, uses an incremental borrowing rate based on the information available at the lease commencement date. In November 2023, the Company entered into a lease amendment that extended the lease by 12 months through December 31, 2024 and contained two options to extend the term of the lease for an additional 12 months each. Each option shall be exercisable, if at all, by giving a nine-month written notice to the landlord. In April 2024, the Company extended the option to extend the term of the lease for an additional 12 months (into December 2025). The extension was included in the December 31, 2023 financials. For the years ended December 31, 2024 and 2023, right of use assets obtained in exchange for lease obligations were $0.3 million and $0.5 million, respectively.

As of December 31, 2024, the Company maintained an unamortized Right-Of-Use asset with a corresponding operating lease liability of approximately $0.3 million based on the present value of the minimum rental payments in accordance with ASC Topic 842, Leases. The weighted average discount rate used for leases as of December 31, 2024 is 9.1%. The weighted average lease term as of December 31, 2024 is 1.0 year. The operating lease expense for the year ended December 31, 2024 was$0.3 million. Maturities and balance sheet presentation of our lease liabilities for all operating leases as of December 31, 2024 is as follows:

The Company’s gross future minimum payments under all non-cancellable operating leases as of December 31, 2024 are:

OPTION AGREEMENT

AbbVie Option Agreement

On October 31, 2023 (the Option Agreement Effective Date), the Company entered into an exclusive option agreement (the Option Agreement) with AbbVie Inc. (AbbVie), pursuant to which the Company granted AbbVie an exclusive option (the Option) to obtain (a) a co-exclusive license in the United States to facilitate a collaboration with the Company to develop, manufacture, and commercialize reproxalap in the United States, (b) an exclusive license to develop, manufacture and commercialize reproxalap outside the United States, (c) a right of first negotiation for compounds that are owned or otherwise controlled by the Company in the field of ophthalmology relating to treating conditions of the ocular surface, and (d) a right to review data for any other compounds that are owned or otherwise controlled by the Company in the fields of ophthalmology and immunology before such data is shared with any other third party (the Collaboration Agreement). AbbVie has paid the Company a non-refundable payment of $1.0 million in consideration of the Option (the Option Payment).

On December 21, 2023, pursuant to the Option Agreement, AbbVie extended the period during which it may exercise the Option (the Exercise Period Extension) by paying the Company a non-refundable payment of $5.0 million (the Option Extension Fee). If the Collaboration Agreement is entered into, the Option Payment and the Option Extension Fee will be credited against the upfront cash payment payable by AbbVie.

On November 15, 2024, the Company entered into the Expansion Side Letter (the Expansion Letter) with AbbVie, which amended certain terms of the Option Agreement. The Expansion Letter makes certain changes to the Option Agreement, among other things, providing that the Company will conduct certain launch activities, which costs shall not exceed mid-single-digit millions of dollars without AbbVie’s approval, and which costs will be considered allowable expenses pursuant to the Collaboration Agreement upon the delivery of AbbVie’s written notice of exercising the Option and entry into the Collaboration Agreement, such that 60% of our allowable expenses will be reimbursed by AbbVie in the event of exercise. If AbbVie does not deliver a written notice of exercising the Option and the Company and AbbVie do not execute the Collaboration Agreement, the Company will remain solely responsible for such launch activities costs. AbbVie has also independently initiated pre-commercialization planning activities. In addition, the Exercise Period (as defined in the Option Agreement) was further modified to ten (10) business days following the date, if any, that the Company receives approval from the U.S. Food and Drug Administration of the NDA for reproxalap in dry eye disease (the FDA Decision), provided that AbbVie shall provide the Company notice in case AbbVie determines that it will not exercise the Option.

Upon AbbVie’s delivery of the agreement execution notice and the parties entering into the Collaboration Agreement, AbbVie would pay the Company a $100 million upfront cash payment, less the Option Payment and the Option Extension Fee. In addition, the Company would be eligible to receive up to approximately $300 million in regulatory and commercial milestone payments, inclusive of a $100 million milestone payment payable if the FDA Decision is received prior to or after the execution. In the United States, the Company would share profits and losses with AbbVie from the commercialization of reproxalap according to a split of 60% for AbbVie and 40% for the Company. Outside of the United States, the Company would be eligible to receive tiered royalties on net sales of reproxalap. As of February 28, 2025, AbbVie has not exercised the Option.

As of December 31, 2023, the Company had recognizedno collaboration revenue and had $6.0 million of deferred long-term collaboration revenue related to the Option Agreement and Exercise Period Extension. During the three months ended September 30, 2024, the deferred collaboration revenue was reclassified from a long-term liability to a current liability due to the Option expiring pursuant to the terms of the Option Agreement in less than one year. Although the Option Agreement was not considered to be a vendor-customer relationship, the Company used FASB ASC Topic 606, Revenue from Contracts with Customers, to conclude that the $6.0 million liability would be considered a transaction price (the Transaction Price), and all other amounts due to the Company under the Collaboration Agreement would be excluded from the Transaction Price, since such amounts relate to fees that can only be achieved subsequent to the exercise of the Option. Because the Option Extension Fee and the Option Payment are creditable against the Collaboration Agreement payments due to the Company, the Transaction Price was allocated to a single unit of account, specifically, the Option to enter into a future Collaboration Agreement which is considered a material right. The Company concluded that all other performance obligations were immaterial promises in the context of the Option Agreement and did not represent additional units of account. The Company will begin to recognize revenue if and when the Option is exercised or when the Option expires.

SEGMENT REPORTING

The Company operates through a single operating and reportable segment focused on the discovery and development of innovative therapies designed to treat immune-mediated and metabolic diseases. The segment's approach is to develop pharmaceuticals that modulate protein systems, instead of directly inhibiting or activating single protein targets, with the goal of optimizing multiple pathways at once while minimizing toxicity. The Company's late-stage product candidates are reproxalap, a RASP modulator for the potential treatment of dry eye disease and allergic conjunctivitis, and ADX‑2191, a novel formulation of intravitreal methotrexate for the potential treatment of retinitis pigmentosa. The Company's preclinical RASP platform includes ADX‑248, ADX‑743, ADX‑631, ADX‑246, and other product candidates in development for inflammatory and metabolic diseases. The Company's tangible assets are held in the United States. The Company manages all business activities on a consolidated basis. The Company's chief operating decision maker is the Chief Executive Officer.

The accounting policies of the operating segment are the same as those described in Note 2, Summary of Significant Accounting Policies. The chief operating decision maker evaluates the performance of the operating segment and allocates resources based on net income (loss) that also is reported on the consolidated income statement as net loss. The measure of the operating segment assets is reported on the consolidated balance sheet as total assets.

The chief operating decision maker uses net income (loss) to monitor budget versus actual results and to analyze cash flows in assessing performance of the segment and allocating resources. The significant expenses are presented on the Company’s Consolidated Statements of Operations.
