Eledon Pharmaceuticals Inc

Note 1. Description of Business

Eledon Pharmaceuticals, Inc. is a clinical stage biotechnology company using its immunology expertise in targeting the CD40 Ligand (“CD40L” or “CD154”) pathway to develop therapies to protect transplanted organs and prevent rejection, and to treat amyotrophic lateral sclerosis (“ALS”). The Company’s lead compound in development is tegoprubart, an IgG1, anti-CD40L antibody with high affinity for the CD40 Ligand, a well-validated biological target that we believe has broad therapeutic potential. Unless otherwise indicated, references to the terms “Eledon,” “our,” “us,” “we,” or the “Company” refer to Eledon Pharmaceuticals, Inc. and its wholly owned subsidiaries, on a consolidated basis.

On September 14, 2020, Eledon acquired Anelixis Therapeutics, Inc. (“Anelixis”), a privately held clinical stage biotechnology company developing a next generation anti-CD40L antibody as a potential treatment for organ and cellular transplantation, autoimmune diseases, and neurodegenerative diseases. The Company maintains its corporate headquarters in Irvine, California and has research and development facilities in Burlington, Massachusetts.

Note 2. Going Concern and Management’s Plans

The accompanying consolidated financial statements have been prepared under the assumption the Company will continue to operate as a going concern, which contemplates the realization of assets and the settlement of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts of liabilities that may result from uncertainty related to the Company’s ability to continue as a going concern.

The Company had a net loss of$40.3 million for the year ended December 31, 2023 and an accumulated deficit of$243.2 million as of December 31, 2023, as a result of incurring losses since our inception. Due to continuing research and development activities, the Company expects to continue to incur net losses into the foreseeable future. The Company expects to continue to incur net losses into the foreseeable future in connection with its ongoing activities, particularly as the Company expands its clinical program with tegoprubart, continues the research and development of, and seeks marketing approval for, its product candidates. In addition, if the Company obtains marketing approval for any of its product candidates, the Company expects to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. The Company has financed operations primarily by net proceeds from the sale of preferred and common stock and warrants.

On April 28, 2023, the Company entered into a Securities Purchase Agreement (the "Securities Purchase Agreement") with certain institutional and accredited investors (the “Purchasers”), pursuant to which the Company agreed to issue and sell to the Purchasers in a private placement (the “Private Placement”) shares of common stock and warrants in a series of three potential closings. On May 5, 2023, the initial closing occurred and the Company received $35.0 million, in exchange for 8,730,168 shares of common stock, pre-funded warrants to purchase 6,421,350 shares of common stock and additional common stock warrants to purchase 15,151,518 shares of common stock (or pre-funded warrants in lieu thereof). The Company may receive up to an additional $105.0 million in tranche financing in a second and a third closing, subject to achieving specified clinical development milestones and volume weighted average share price levels and trading volume conditions, and an additional$45.5 million assuming the exercise of all common stock warrants issued in the initial closing of the Private Placement. See Note 10. “Stockholders’ Equity” for further information regarding the Private Placement. Due to the contingent nature of the exercise of the common stock warrants and the second and third closings of the Private Placement, accounting principles generally accepted in the United States of America (“GAAP”) requires the Company to exclude them from its going concern analysis. If these events do not occur or the Company is unable to secure additional capital or is unable to do so on acceptable terms, it will be forced to significantly alter its business strategy, substantially curtail its current operations, or liquidate and cease operations altogether.

As of December 31, 2023, the Company had cash and cash equivalents and short-term investments of approximately$51.1 million. Additionally, in view of the Company’s expectation to incur significant losses for the foreseeable future, the Company will be required to raise additional capital resources in order to fund its operations, although the availability of, and the Company’s access to, such resources is not assured. Accordingly, management believes that there is substantial doubt regarding the Company’s ability to continue operating as a going concern through at least the next twelve months from the date of this filing.

Note 3. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The consolidated financial statements are prepared in accordance with GAAP. Eledon, a Delaware corporation, owns 100% of the issued and outstanding common stock or other ownership interest in Anelixis Therapeutics, LLC, a Delaware limited liability company, and Otic Pharma, Ltd., a private limited company organized under the laws of the State of Israel (“Otic”). Otic owns 100% of the issued and outstanding common stock or other ownership interest in its U.S. subsidiary, Otic Pharma, Inc. The functional currency of the Company’s foreign subsidiary is the U.S. Dollar; however, certain expenses, assets and liabilities are transacted at the local currency. These transactions are translated from the local currency into U.S. Dollars at exchange rates during or at the end of the reporting period. The activities of the Company’s foreign subsidiary are not significant to the consolidated financial statements.

All significant intercompany accounts and transactions among the entities have been eliminated in consolidation.

Use of Estimates

The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make informed estimates and assumptions that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in the Company’s consolidated financial statements and accompanying notes. The most significant estimates in the Company’s consolidated financial statements relate to stock-based compensation, accruals for liabilities, impairment of long-lived assets, and other matters that affect the consolidated financial statements and related disclosures. Actual results could differ materially from those estimates under different assumptions or conditions and the differences may be material to the consolidated financial statements.

Concentration of Credit Risk

Financial instruments which potentially subject the Company to significant concentration of credit risk consists of cash, cash equivalents and short-term investments. The Company maintains deposits in federally insured institutions in excess of federally insured limits and invests in short-term investments with the primary objective of seeking to preserve principal, achieve liquidity requirements and safeguard invested funds. We believe that the Company is not exposed to significant credit risk due to the financial position of the depository institution in which those deposits are held and the nature, including the credit ratings, of our cash equivalents and short-term investments, but we have not eliminated all credit risk.

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities ofthree months or less when purchased to be cash equivalents. Cash and cash equivalents include cash in readily available checking accounts, money market funds, U.S. government securities and U.S. government agency securities. Cash and cash equivalents are valued at cost, which approximates their fair value due to the short-term maturities of these investments.

Risks and Uncertainties

As of December 31, 2023 and 2022, all of the Company’s long-lived assets were located in the United States.

The Company’s products will require approval from the U.S. Food and Drug Administration (“FDA”) and foreign regulatory agencies before commercial sales can commence. There can be no assurance that its products will receive any of these required approvals. The denial or delay of such approvals may impact the Company’s business in the future. In addition, after the approval by the FDA, there is still an ongoing risk of adverse events that did not appear during the product approval process.

The Company is subject to risks common to companies in the pharmaceutical industry, including, but not limited to, new technological innovations, clinical development risk, establishment of appropriate commercial partnerships, protection of proprietary technology, compliance with government and environmental regulations, uncertainty of market acceptance of products, product liability, the volatility of its stock price and the need to obtain additional financing.

The Company's facilities and equipment, including those of the Company's suppliers and vendors, may be affected by natural or man-made disasters. The Company's administrative office is based in Irvine, California and the Company manages allits research and development activities through third parties that are located throughout the world. The Company has taken precautions to safeguard its facilities, equipment and systems, including insurance, health and safety protocols, and off-site storage of computer data. However, the Company's facilities and systems, as well as those of its third-party suppliers and vendors, may be vulnerable to earthquakes, fire, storm, public health or similar emergencies, power loss, telecommunications failures, physical and software break-ins, software viruses and similar events which could cause substantial delays in its operations, damage or destroy its equipment or inventory, and cause the Company to incur additional expenses and delay research and development activities. In addition, the insurance coverage the Company maintains may not be adequate to cover its losses in any circumstance and may not continue to be available to use on acceptable terms, or at all.

Reportable Segments

Operating segments under GAAP are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the Chief Operating Decision Maker (“CODM”), or decision-making group, in deciding how to allocate resources and in assessing performance. The CODM is the Company’s Chief Executive Officer and the Company has determined that it operates inone business segment, which is the development of products for therapeutic medicines selectively targeting critical pathways associated with the underlying molecular pathogenesis for patients with severe inflammation and autoimmune diseases.

Goodwill

Goodwill represents the difference between the consideration transferred and the fair value of the net assets acquired under the acquisition method of accounting. Goodwill is not amortized but is evaluated for impairment as of December 31 of each year or if indicators of impairment exist that would, more likely than not, reduce the fair value from its carrying amount.

The Company performs its goodwill impairment analysis at the reporting unit level, which aligns with the Company’s reporting structure and availability of discrete financial information. The Company performs its annual impairment analysis by either comparing the reporting unit’s estimated fair value to its carrying amount or doing a qualitative assessment of a reporting unit’s fair value from the last quantitative assessment to determine if there is potential impairment. The Company may do a qualitative assessment when the results of the previous quantitative test indicated the reporting unit’s estimated fair value was significantly in excess of the carrying value of its net assets and it does not believe there have been significant changes in the reporting unit’s operations that would significantly decrease its estimated fair value or significantly increase its net assets. If a quantitative assessment is performed, the evaluation includes management estimates of cash flow projections based on internal future projections and/or use of a market approach by looking at market values of comparable companies. Key assumptions for these projections include revenue growth, future gross and operating margin growth, and its weighted cost of capital and terminal growth rates. The revenue and margin growth is based on increased sales of new products as the Company maintains investments in research and development. Additional assumed value creators may include increased efficiencies from capital spending. The resulting cash flows are discounted using a weighted average cost of capital. Operating mechanisms and requirements to ensure that growth and efficiency assumptions will ultimately be realized are also considered in the evaluation, including timing and probability of regulatory approvals for Company products to be commercialized. The Company’s market capitalization is also considered as a part of its analysis.

The Company’s annual evaluation for impairment of goodwill consists ofone reporting unit. In accordance with the Company’s policy, the Company completed its annual evaluation for impairment using the quantitative assessment, utilizing the market approach and due to declining market conditions, determined that the fair value of the reporting unit was below its carrying value. As a result, the Company recognized $48.6 million of goodwill impairment, reducing the goodwill balance tozero for the year ended December 31, 2022, and accordingly, no goodwill impairment was recorded for the year ended December 31, 2023.

Long-Lived Assets

Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Additions, major renewals and improvements are capitalized and repair and maintenance costs are charged to expense as incurred. Leasehold improvements are amortized over the remaining life of the initial lease term or the estimated useful lives of the assets, whichever is shorter.

The Company reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. An impairment loss would be recognized when estimated future undiscounted cash flows relating to the asset are less than its carrying amount. An impairment loss is measured as the amount bywhich the carrying amount of an asset exceeds its fair value. Significant management judgment is required in the forecast of future operating results that are used in the preparation of expected cash flows. No impairments of long-lived assets have been identified during the years presented.

In-Process Research and Development

The fair values of in-process research and development (“IPR&D”) projects acquired in a business combination that are not complete are capitalized and accounted for as indefinite-lived intangible assets until completion or abandonment of the related research and development (“R&D”) efforts. Upon successful completion of the project, the capitalized amount is amortized over its estimated useful life. If a project is abandoned, all remaining capitalized amounts are written off immediately. Major risks and uncertainties are often associated with IPR&D projects because we are required to obtain regulatory approvals before marketing the resulting products. Such approvals require completing clinical trials that demonstrate a product candidate is safe and effective. Consequently, the eventual realized value of the acquired IPR&D project may vary from its fair value at the date of acquisition, and IPR&D impairment charges may occur in future periods.

Capitalized IPR&D projects are tested for impairment annually and whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. We consider various factors for potential impairment, including the current legal and regulatory environment and the competitive landscape. Adverse clinical trial results, significant delays in obtaining marketing approval, the inability to bring a product to market and the introduction or advancement of competitors’ products could result in partial or full impairment of the related intangible assets.

Research and development expenses include personnel and facility-related expenses, outside contracted services including clinical trial costs, manufacturing and process development costs, research costs and other consulting services and non-cash stock-based compensation. Research and development costs are expensed as incurred. Amounts due under contracts with third parties may be either fixed fee or fee for service, and may include upfront payments, monthly payments and payments upon the completion of milestones or receipt of deliverables. Non-refundable advance payments under agreements are capitalized and expensed as the related goods are delivered or services are performed.

The Company’s contracts with third parties to perform various clinical trial activities in the on-going development of potential products. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows to its vendors. Payments under the contracts depend on factors such as the achievement of certain events, successful enrollment of patients, and completion of portions of the clinical trial or similar conditions. The Company’s accrual for clinical trials is based on estimates of the services received and efforts expended pursuant to contracts with clinical trial centers and clinical research organizations. These contracts may be terminated by the Company upon written notice and the Company is generally only liable for actual effort expended by the organizations to the date of termination, although in certain instances the Company may be further responsible for termination fees and penalties. The Company estimates its research and development expenses and the related accrual as of each balance sheet date based on the facts and circumstances known to the Company at that time. There have been no material adjustments to the Company’s prior period accrued estimates for clinical trial activities through December 31, 2023.

Net Loss Per Share

Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares and potentially dilutive securities outstanding for the period determined using the treasury-stock and if-converted methods. For purposes of the diluted net loss per share calculation, incentive stock options, restricted stock units and warrants are considered to be potentially dilutive securities and are excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive. Therefore, basic and diluted net loss per share was the same for the periods presented due to the Company’s net loss position. Basic weighted average shares outstanding for the years ended December 31, 2023 and 2022 include 5,776,270 and 509,117, respectively, shares underlying pre-funded warrants to purchase common shares. Asthe shares underlying these pre-funded warrants can be issued for little consideration(an exercise price per share equal to $0.001 per share), these shares are deemed to be issued for purposes of basic earnings per share.

The computation of diluted earnings per share excludes incentive stock options, restricted stock units, and warrants that are anti-dilutive. The following table provides a summary as of December 31, 2023 and 2022 common share equivalents that were excluded because their inclusion would have been anti-dilutive.

Stock-Based Compensation

The Company recognizes compensation expense for all stock-based awards based on the grant-date estimated fair value.

The fair value of stock options is determined using the Black-Scholes option pricing model, using assumptions which are subjective and require significant judgment and estimation by management. The risk-free rate assumption was based on observed yields from governmental zero-coupon bonds with an equivalent term. The expected volatility assumption was based on historical volatilities of a group of comparable industry companies whose share prices are publicly available. The peer group was developed based on companies in the pharmaceutical industry. The expected term of stock options represents the weighted-average period that the stock options are expected to be outstanding. Because the Company does not have historical exercise behavior, the Company determined the expected life assumption using the simplified method for stock options granted to employees, which is an average of the options ordinary vesting period and the contractual term. The expected dividend assumption was based on the Company’s history and expectation of dividend payouts. The Company has not paid and does not expect to pay dividends at any time in the foreseeable future. The Company recognizes forfeitures on an actual basis and as such did not estimate forfeitures to calculate stock-based compensation.

Restricted Stock Units (“RSUs”) are measured and recognized based on the quoted market price of our common stock on the date of grant.

Income Taxes

Significant judgment is required in determining the Company’s provision for income taxes, deferred tax assets and liabilities and the valuation allowance recorded against net deferred tax assets. We assess the likelihood that deferred tax assets will be recovered as deductions from future taxable income. The evaluation of the need for a valuation allowance is performed on a jurisdiction-by-jurisdiction basis and includes a review of all available positive and negative evidence. Factors reviewed include projections of pre-tax book income for the foreseeable future, determination of cumulative pre-tax book income after permanent differences, earnings history, and reliability of forecasting. We have provided a valuation allowance on our deferred tax assets as of December 31, 2023 and 2022 because we believe it is more likely than not that a majority of our deferred tax assets will not be realized as of this date.

The Company evaluates the accounting for uncertainty in income tax recognized in its consolidated financial statements and determines whether it is more likely than not that a tax position will be sustained upon examination by the appropriate taxing authorities before any part of the benefit is recorded in its consolidated financial statements. For those tax positions where it is “not more likely than not” that a tax benefit will be sustained, no tax benefit is recognized. Where applicable, associated interest and penalties are also recorded. The Company has not accrued any liabilities for any such uncertain tax positions as of December 31, 2023 and 2022. The Company is subject to U.S. federal and state tax authority examinations for all the years since inception due to net operating loss and tax credit carryforwards. The net operating losses and tax credits are subject to adjustment until the statute closes on the year the attributes are ultimately utilized.

The Company’s income tax returns are based on calculations and assumptions that are subject to examination by the Internal Revenue Service and other tax authorities. In addition, the calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. While the Company believes it has appropriate support for the positions taken on its tax returns, the Company regularly assesses the potential outcomes of examinations by tax authorities in determining the adequacy of its provision for income taxes. The Company continually assesses the likelihood and amount of potential revisions and adjusts the income tax provision, income taxes payable and deferred taxes in the period in which the facts that give rise to a revision become known. For additional information, see Note 9. Income Taxes.

Recent Accounting Pronouncements Issued But Not Adopted

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This update requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. ASU No. 2023-09 is effective for public entities with annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This update requires public entities to disclose information about their reportable segments’ significant expenses and other segment items on an interim and annual basis. Public entities with a single reportable segment are required to apply the disclosure requirements in ASU 2023-07, as well as all existing segment disclosures and reconciliation requirements in ASC 280, on an interim and annual basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 and for interim periods beginning after December 15, 2024, with early adoptions permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the American Institute of Certified Public Accountants, and the SEC did not, or are not believed by management to, have a material impact on the Company’s present or future financial position, results of operations or cash flows.

Note 4. Short-Term Investments

The objectives of the Company’s investment policy are to preserve principal, meet the Company's liquidity requirements and safeguard invested funds. Short-term investments consist of U.S. government securities and U.S. government agency securities. The Company has classified these investments as available-for-sale securities, as the sale of such investments may be required prior to maturity to implement management strategies, and therefore has classified all investments with maturity dates beyond three months at the date of purchase as current assets in the accompanying unaudited condensed consolidated balance sheets. Any premium or discount arising at purchase is amortized and/or accreted to interest income as an adjustment to yield using the straight-line method over the life of the instrument. The amortized cost of available-for-sale securities is adjusted for amortization of premiums and accretion of discounts to maturity. Investments are reported at their estimated fair value. Unrealized gains and losses are included in accumulated other comprehensive loss as a component of stockholders' equity until realized.

The following is a summary of short-term investments, which were classified as available-for-sale securities as of December 31, 2023:

All of the Company's available-for-sale securities have a stated maturity of less than one year. The Company didnot hold any short-term investments as of December 31, 2022.

Note 5. Fair Value Measurements

Financial assets and liabilities are recorded at fair value.

The Company classifies fair value measurements using a three-level hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

•

Level 1—Quoted market prices (unadjusted) in active markets for identical assets and liabilities.

•

Level 2—Observable inputs other than quoted market prices included in Level 1, such as quoted market prices for markets that are not active or other inputs that are observable or can be corroborated by observable market data.

•

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, including certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. These fair values are obtained from independent pricing services which utilize Level 1 and Level 2 inputs.

The following table summarizes the Company's financial instruments measured at fair value on a recurring basis as of December 31, 2023 and 2022. Included within cash and cash equivalents on the consolidated balance sheets, but excluded from the fair value hierarchy table, are cash deposits held at financial institutions.

Note 6. Prepaid Expenses, Other Assets, Accrued Expenses and Other Liabilities

Prepaid expenses and other current assets consisted of the following as of December 31, 2023 and 2022 (in thousands):

Accrued expenses and other liabilities consisted of the following as of December 31, 2023 and 2022 (in thousands):

Note 7. Goodwill

In 2022, the Company determined that the sustained decrease in our market capitalization constituted an indicator of impairment and as a result, a quantitative goodwill impairment test, utilizing the market approach, determined that the fair value of the reporting unit was below its carrying value and the goodwill was fully impaired.

The Company recorded an impairment of $48.6 million for the year ended December 31, 2022 for the full write-down of the goodwill recorded as part of the acquisition of Anelixis. No impairment was recorded for the year ended December 31, 2023.

Note 8. Commitments and Contingencies

Operating Leases

The Company leases office space under various operating leases. Total rent expense for all operating leases in the consolidated statements of operations and comprehensive loss was approximately $0.4 million for each of the years ended December 31, 2023 and 2022.

The Company has an operating lease for 5,197 square feet of office space in Irvine, California, that expires on December 31, 2024, as amended.

On November 4, 2021, the Company entered into an operating lease for 6,138 square feet of office space in Burlington, Massachusetts, that expires on November 20, 2024.

The Company determines if a contract contains a lease at inception. Our office leases have remaining terms of approximately 12 months and do not include options to extend the leases for additional periods.

Operating lease assets and liabilities are recognized at the lease commencement date. Operating lease liabilities represent the present value of lease payments not yet paid. Operating lease assets represent our right to use an underlying asset and are based upon the operating lease liabilities as adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of operating lease assets. To determine the present value of lease payments not yet paid, we estimate incremental secured borrowing rates corresponding to the maturities of the leases. As we haveno outstanding debt nor committed credit facilities, secured or otherwise, we estimate this rate based on prevailing financial market conditions, comparable company and credit analysis, and management’s judgment.

Our leases contain rent escalations over the lease term. We recognize expense for these leases on a straight-line basis over the lease term. Additionally, tenant incentives used to fund leasehold improvements are recognized when earned and reduce our right-of-use asset related to the lease. These are amortized through the right-of-use asset as reductions of expense over the lease term. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

While we do not currently have any lease agreement with lease and non-lease components, we elected to account for lease and non-lease components as separate components.

We have elected the short-term lease recognition exemption for all applicable classes of underlying assets. Short-term disclosures include only those leases with a term greater than one month and 12 months or less, and expense is recognized on a straight-line basis over the lease term. Leases with an initial term of 12 months or less, that do not include an option to purchase the underlying asset that we are reasonably certain to exercise, are not recorded on the consolidated balance sheet.

The components of lease expense were as follows (in thousands):

Other information related to leases was as follows (in thousands, except lease term and discount rate):

Future payments under noncancelable operating leases having initial or remaining terms of one year or more are as follows for the succeeding fiscal year and thereafter (in thousands):

Grants and Licenses

ALS Therapy Development Foundation, Inc. License Agreement

In May 2015, Anelixis executed a License Agreement (the “Agreement”), which is an exclusive patent rights agreement with ALS Therapy Development Foundation, Inc. (“ALS TDI”) for certain patents and “know-how” of ALS TDI. This agreement continues until the licensee terminates the agreement with ninety days written notice. The Agreement requires license fees payable to ALS TDI, subject to the achievement of certain milestones and other conditions.

The first and second milestones of the Agreement are the dosing of the first subjects in a first toxicity study in non-human primates and the dosing of the first patient in a Phase I Clinical Trial, respectively. Both of these milestones were achieved as of December 31, 2018 and 2017. The fee due for the achievement of these milestones was $1.0 million each. During 2018 and 2017, Anelixis issued $1.0 million worth of its common stock in lieu of making a cash payment. There wereno milestones achieved during 2023 or 2022.

The Agreement was amended and restated in February 2020, and a first amendment to the restated license agreement was executed in September 2020. As amended in September 2020, the remaining milestone payments for a first licensed product total $6.0 million. In the event that the Company develops a second licensed product, the Company is obligated to pay up to $2.5 million in additional milestone payments.

In addition to the milestone payments, the Company is required to pay ALS TDI an amended annual license maintenance fee of $0.1 million beginning on the earlier of January 1, 2022, the Company’s first sublicense, or change in control, as defined in the Agreement. The Company made a $0.1 million annual license maintenance fee in each of 2023 and 2022.

Furthermore, the Company shall pay ALS TDI fees based on reaching certain levels of annual net sales of any product produced with the patent rights. A royalty in the low single digits will be due on aggregate net sales. Upon the first calendar year of reaching $500.0 million in aggregate net sales, the Company shall pay ALS TDI a one-time milestone payment of $15.0 million. Upon the first calendar year of reaching $1.0 billion in aggregate net sales, the Company is obligated to pay ALS TDI a one-time milestone payment of $30.0 million.

Lonza Sales AG Inc. License Agreement

In September 2018, Anelixis executed a License Agreement (the “Lonza Agreement”), which is a manufacturing know-how rights agreement with Lonza Sales AG Inc. (“Lonza”) for the use of certain processes and know-how related to the manufacture of tegoprubart. The Lonza Agreement continues until the later of the last Valid Claim (as defined therein) or ten years from the First Commercial Sale of tegoprubart, as defined and subject to the conditions therein. A royalty in the low single digits will be due on aggregate net sales of tegoprubart that is manufactured by Lonza or any other third-party or licensee.

eGenesis, Inc. Collaboration Agreement

In September 2022, and subsequently amended in January 2023, Eledon executed a non-exclusive collaborative research agreement with eGenesis, Inc. (the “eGenesis Agreement”), under which eGenesis will gain access to tegoprubart for eGenesis’ ongoing preclinical research and development xenotransplant studies of human-compatible organs and cells for the treatment of organ failure. eGenesis will pay Eledon for supplies of tegoprubart based on the number of study days per animal needed for the eGenesis preclinical xenotransplant studies. The eGenesis agreement continues until September 2025, unless terminated earlier by either party.

Legal Matters

The Company and its subsidiaries are not a party to or the subject of any claim or lawsuit that individually or in the aggregate is anticipated to have a material effect on the Company’s results of operations, financial condition or cash flows.

Indemnifications

In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnification. The Company’s exposure under these agreements is unknown because it involves future claims that may be made against the Company but have not yet been made. To date, the Company has not paid any claims or been required to defend any action related to its indemnification obligations. However, the Company may record charges in the future because of these indemnification obligations. No amounts associated with such indemnifications have been recorded to date.

Contingencies

From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of business activities. The Company accrues a liability for such matters when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. There have beenno contingent liabilities requiring accrual at December 31, 2023 and 2022.

Note 9. Income Taxes

Loss before income taxes are as follows (in thousands):

The provision (benefit) for income taxes are as follows (in thousands):

The Company is subject to income taxes under U.S. tax laws. The Company is subject to an Israeli corporate tax rate of 23% in 2020 and thereafter. The Company was subject to a blended U.S. tax rate (federal as well as state corporate tax) of 21% in 2023 and 2022.

Significant judgment is required in determining the Company’s provision for income taxes, deferred tax assets and liabilities and the valuation allowance recorded against net deferred tax assets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. A valuation allowance is established when it is more likely than not the future realization of all or some of the deferred tax assets will not be achieved. The evaluation of the need for a valuation allowance is performed on a jurisdiction-by-jurisdiction basis, and includes a review of all available positive and negative evidence. Factors reviewed include projections of pre-tax book income for the foreseeable future, determination of cumulative pre-tax book income after permanent differences, earnings history, and reliability of forecasting.

Based on its review, the Company concluded that it was more likely than not that they would not realize the benefit of a portion of its deferred tax assets in the future. This conclusion was based on historical and projected operating performance, as well as the Company’s expectation that its operations will not generate sufficient taxable income in future periods to realize the tax benefits associated with the deferred tax assets within the statutory carryover periods. Therefore, the Company has a valuation allowance on its deferred tax assets as of December 31, 2023.

The Company will continue to assess the need for a valuation allowance on its deferred tax assets by evaluating both positive and negative evidence that may exist. Any adjustment to the net deferred tax asset valuation allowance would be recorded in the statement of operations for the period that the adjustment is determined to be required.

A reconciliation of the U.S. federal statutory income tax rate to the Company’s effective income tax rate is as follows (in thousands):

Significant components of the Company’s deferred tax assets and liabilities as of December 31, 2023 and 2022 consisted of the following (in thousands):

The following table reconciles the beginning and ending amounts of unrecognized tax benefits for the years presented (in thousands):

The deferred income tax assets have been offset by a valuation allowance, as realization is dependent on future earnings, if any, the timing and amount of which are uncertain. The net valuation allowance increased by $9.1 million from December 31, 2022 to December 31, 2023. The net valuation allowance increased by $9.4 million from December 31, 2021 to December 31, 2022.

The Company’s accounting for deferred taxes involves the evaluation of a number of factors concerning the realizability of its net deferred tax assets. The Company primarily considered such factors as its history of operating losses, the nature of the Company’s deferred tax assets, and the timing, likelihood, and amount, if any, of future taxable income during the periods in which those temporary differences and carryforwards become deductible. At present, the Company does not believe that it is more likely than not that the deferred tax assets will be realized; accordingly, a valuation allowance has been established.

As of December 31, 2023 and 2022, the Company had federal net operating loss carryforwards of approximately $68.9 million and $56.8 million, respectively, available to reduce future taxable income. As of December 31, 2023 and 2022, the Company also has state net operating loss carryforwards of $30.1 million and $25.0 million, respectively. Both the federal and state net operating loss carryforwards incurred before 2018 begin expiring in 2035, if not utilized. The federal net operating losses incurred since 2018 of $68.0 million do not expire. The state net operating losses begin to expire in 2035. As of December 31, 2023 and 2022, the Company had Israeli net operating losses of $7.9 million, which carryforward indefinitely.

As of December 31, 2023 and 2022, the Company had federal research and development tax credit carryforwards of approximately $4.0 million and $2.4 million, respectively. If not utilized, the carryforwards will begin expiring in 2036. As of December 31, 2023 and 2022, the Company has state research and development credit carryforwards or approximately $1.5 million and $1.2 million, respectively, which will begin expiring in 2030 if not utilized.

Pursuant to Internal Revenue Code (“IRC) Sections 382 and 383, annual use of the Company’s net operating loss and research and development credit carryforwards may be limited in the event a cumulative change in ownership of more than

50% occurs within athree-year period. The Company has not completed an IRC Section 382/383 analysis regarding the limitation of net operating loss and research and development credit carryforwards. Due to the existence of the valuation allowance, future changes in the Company’s unrecognized tax benefits will not impact the Company’s effective tax rate.

The Company’s ability to use its remaining net operating loss and tax credit carryforwards may be further limited if the Company experiences a Section 382 ownership change in connection with future changes in our stock ownership.

In the United States, the Company files income tax returns in the U.S. Federal jurisdiction, California and Massachusetts. The Company’s tax years for 2018 and forward are subject to examination by the Federal and California tax authorities due to the carryforward of unutilized net operating losses and research and development credits.

The Company’s policy is to recognize interest expense and penalties related to income tax matters as a component of income tax expense. There wasno accrued interest and penalties associated with uncertain tax positions as of December 31, 2023 and 2022. The Company hasnot recorded any interest or penalties in 2023 or 2022.
