NRX Pharmaceuticals Inc

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2024

1. Organization

The Business

NRx Pharmaceuticals, Inc. (Nasdaq: NRXP) (“NRX” or the* “Company”) is a clinical-stage bio-pharmaceutical company which develops and intends to distribute, through its wholly-owned operating subsidiaries, NeuroRx, Inc., (“NeuroRx”) and HOPE Therapeutics, Inc. (“HOPE”), and collectively with NRX and NeuroRx, the “Company”, “we”, “us”, or “our”), novel therapeutics for the treatment of central nervous system disorders including suicidal depression, chronic pain, and post-traumatic stress disorder (“PTSD”) and now schizophrenia. All of our current drug development activities are focused drugs that modulate on the N-methyl-D-aspartate (“NMDA”) receptor in the brain and nervous system, a neurochemical pathway that has been disclosed in detail in our annual filings. NeuroRx is organized as a traditional research and development (“R&D”) company, whereas HOPE is organized as a specialty pharmaceutical company intended to distribute ketamine and other therapeutic options to clinics that serve patients with suicidal depression and PTSD. The Company hastwo* lead drug candidates that are expected to be submitted by year end for Food and Drug Administration (“FDA”) approval with anticipated FDA decision dates under the Prescription Drug User Fee Act ("PDUFA") by the end of* June**2025:* NRX-101, an oral fixed dose combination of D-cycloserine and lurasidone and NRX-100, a preservative-free formulation of ketamine for intravenous infusion. In* February 2024,the Company incorporated HOPE as a wholly-owned subsidiary and in August 2024completed a carve-out audit of HOPE's financial statements which are necessary for the intended Spin-Off (as defined in Note7*) of HOPE to the Company's shareholders at a future date.

Operations

The Company’s drug development activities have expanded from its original focus on development of NRX-101, a fixed dose combination of D-cycloserine (DCS) and lurasidone for the treatment of suicidal bipolar depression to encompass the development of NRX-101 for the treatment of chronic pain and PTSD and to the development of intravenous ketamine (NRX-100/HTX-100) for the treatment of suicidal depression. These additional indications have been added as the Company has gained access to clinical trials data funded by governmental entities in France and potentially in the United States which has the potential to afford the Company potential safety and efficacy data on key indications at low cost.

2. Going Concern

These consolidated financial statements have been prepared on a going concern basis which contemplates the realization of assets and settlement of liabilities and commitments in the normal course of business. Since inception, the Company has experienced net losses and negative cash flows from operations each fiscal year and has a working capital deficit at* September 30, 2024*. The Company hasno revenues and expects to continue to incur operating losses for the remainder of2024. Although the Company projects operating revenue to be derived from the operation of clinical facilities through its HOPE subsidiary and sales of its pharmaceutical products in2025, these projections are subject to completion of anticipated clinical acquisitions in thefirst case and regulatory approvals in the latter case. In the absence of these projected developments, the Company’s ability to support its ongoing capital needs is dependent on its ability to continue to raise equity and/or debt financing, which* may**not* be available on favorable terms, or at all, in order to continue operations.

As of* September 30, 2024*, the Company had $1.6 million in cash and cash equivalents. On* August 12, 2024,the Company entered into that certain Securities Purchase Agreement dated August 12, 2024 (the “Purchase Agreement”) with certain accredited investors (the “Investors”), pursuant to which the Company agreed to sell Senior Secured Convertible Promissory Notes (the “Anson Notes”) in the aggregate principal amount of up to approximately $16.3 million inthree tranches of $5.435 million, and warrants to purchase that amount of shares of the Company’s Common Stock equal to50%* of the principal amount of the Notes in the respective tranche divided by the volume weighted average price (“VWAP”) of the Company’s Common Stock, as listed on the Nasdaq Capital Market, on the day prior to the closing of each respective tranche under the Purchase Agreement (the “Anson Warrants”). The Company consummated the sale of thefirst tranche of $5.435 million ($4.5 million in net proceeds) in Notes and Warrants (the “First Closing”) on* August 14, 2024 (the “First Closing Date”), and thesecond* tranche of $5.435 million in Notes and Warrants (the “Second Closing”) on* October 10, 2024 (*the “Second Closing Date”), for aggregate gross proceeds of approximately $10.87 million, before deducting fees, costs, and other expenses.

The Company has secured operating capital that it anticipates as sufficient to fund its drug development operations through year end and to finance submission of FDA New Drug Applications for NRX-100 and NRX-101. The Company* maypursue additional equity or debt financing or refinancing opportunities in2024* and2025 to fund ongoing clinical activities, to meet obligations under its current debt arrangements and for general corporate purposes. Such arrangements* maytake the form of loans, equity offerings, strategic agreements, licensing agreements, joint ventures or other agreements. The sale of equity could result in additional dilution to the Company’s existing shareholders. The Company cannot make any assurances that additional financing will be available to it and, if available, on acceptable terms, or that it will be able to refinance its existing debt obligations which could negatively impact the Company’s business and operations and could also lead to a reduction in the Company’s operations. The Company will continue to carefully monitor the impact of its continuing operations on the Company’s working capital needs and debt repayment obligations. As such, the Company has concluded that substantial doubt exists regarding the Company’s ability to continue as a going concern for a period of at leasttwelve* months from the date of issuance of these condensed consolidated financial statements. The accompanying consolidated financial statements donot include any adjustments to reflect the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the company be unable to continue as a going concern.

7

The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The condensed consolidated financial statements donot include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that* may*be necessary if the Company is unable to continue as a going concern.

3. Summary of Significant Accounting Policies

On* April 1, 2024,the Company effected a reverse stock split (the “Reverse Stock Split”) of the Company’s common stock, $0.001 par value (“Common Stock”), at a ratio of1*-for-10. All historical share amounts, with the exception of the Company’s Series A Preferred Stock, disclosed in this Quarterly Report on Form10-Q have been retroactively adjusted to reflect the Reverse Stock Split. No fractional shares were issued as a result of the Reverse Stock Split, as fractional shares of Common Stock were rounded up to the nearest whole share. See Note9. Equity for additional information.

Basis of Presentation and Principles of Consolidation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) as determined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they donot include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the unaudited interim condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of the consolidated balance sheet, statements of operations and cash flows for the interim periods presented. The results of operations for any interim periods arenot necessarily indicative of the results that* may*be expected for the entire fiscal year or any other interim period.

Use of Estimates

The preparation of condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in its consolidated financial statements and the reported amounts of expenses during the reporting period. The most significant estimates in the Company’s condensed consolidated financial statements relate to the fair value of the convertible notes payable, fair value of warrant liabilities, fair value of stock options and warrants, and the utilization of deferred tax assets. These estimates and assumptions are based on current facts, historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of expenses that arenot readily apparent from other sources. Actual results* may*differ materially and adversely from these estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected.

Certain Risks and Uncertainties

The Company’s activities are subject to significant risks and uncertainties including the risk of failure to secure additional funding to properly execute the Company’s business plan. The Company is subject to risks that are common to companies in the pharmaceutical industry, including, butnot limited to, development by the Company or its competitors of new technological innovations, dependence on key personnel, reliance onthird party manufacturers, protection of proprietary technology, and compliance with regulatory requirements.

Fair Value of Financial Instruments

FASB ASC Topic820, Fair Value Measurements(“ASC820**”), provides guidance on the development and disclosure of fair value measurements. Under this accounting guidance, fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability.

8

The accounting guidance classifies fair value measurements inone of the followingthree categories for disclosure purposes:

Level1: Quoted prices in active markets for identical assets or liabilities.

Level2: Inputs other than Level1 prices for similar assets or liabilities that are directly or indirectly observable in the marketplace.

Level3: Unobservable inputs which are supported by little orno market activity and values determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation. (Refer to Note11)

Concentration of Credit Risk and Off-Balance Sheet Risk

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents. Cash equivalents are occasionally invested in certificates of deposit. The Company maintains each of its cash balances with high-quality and accredited financial institutions and accordingly, such funds arenot exposed to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. Deposits in financial institutions* may,from time to time, exceed federally insured limits. As of September 30, 2024* the Company’s cash and cash equivalents balance within money market accounts was in excess of the U.S. federally insured limits by $1.2 million. The Company hasnot experienced any losses on its deposits of cash. The Company maintains a portion of its cash and cash equivalent balances in the form of a money market account with a financial institution that management believes to be creditworthy.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity ofthree months or less at the time of initial purchase to be cash equivalents, including balances held in the Company’s money market accounts. The Company maintains its cash and cash equivalents with financial institutions, in which balances from time to time* may*exceed the U.S. federally insured limits. The objectives of the Company’s cash management policy are to safeguard and preserve funds to maintain liquidity sufficient to meet the Company’s cash flow requirements, and to attain a market rate of return.

Revenue Recognition

The Company accounts for revenue under FASB ASC Topic606, Revenue for Contract with Customers (“ASC606**”) or other accounting standards for revenuenot derived from customers. Arrangements* mayinclude licenses to intellectual property, research services and participation on joint research committees. The Company evaluates the promised goods or services to determine which promises, or group of promises, represent performance obligations. In contemplation of whether a promised good or service meets the criteria required of a performance obligation, the Company considers the stage of research, the underlying intellectual property, the capabilities and expertise of the customer relative to the underlying intellectual property, and whether the promised goods or services are integral to or dependent on other promises in the contract. When accounting for an arrangement that contains multiple performance obligations, the Company must develop judgmental assumptions, which may*include market conditions, timelines and probabilities of regulatory success to determine the stand-alone selling price for each performance obligation identified in the contract.

The Company enters into contractual arrangements that* mayinclude licenses to intellectual property and research and development services. When such contractual arrangements are determined to be accounted for in accordance with ASC606,* the Company evaluates the promised good or services to determine which promises, or group of promises, represent performance obligations. When accounting for an arrangement that contains multiple performance obligations, the Company must develop judgmental assumptions, which* may*include market conditions, timelines and probabilities of regulatory success to determine the stand-alone selling price for each performance obligation identified in the contract.

9

The License Agreement (the “License Agreement”) with Alvogen Pharma US, Inc., Alvogen, Inc. and Lotus Pharmaceutical Co. Ltd. (collectively, “Alvogen”) (as further discussed in Note6 below) was accounted for in accordance with ASC606. In accordance with ASC606, the Company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC606, it performs the followingfive steps:

i. identify the contract(s) with a customer;

ii. identify the performance obligations in the contract;

iii. determine the transaction price;

iv. allocate the transaction price to the performance obligations within the contract; and

v. recognize revenue when (or as) the entity satisfies a performance obligation.

The Company only applies thefive-step model to contracts when it determines that it is probable it will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer.

At contract inception, once the contract is determined to be within the scope of ASC606, the Company assesses the goods or services promised within the contract to determine whether each promised good or service is a performance obligation. The promised goods or services in the Company’s arrangements typically consist of a license to intellectual property and research services. The Company* mayprovide options to additional items in such arrangements, which are accounted for as separate contracts when the customer elects to exercise such options, unless the option provides a material right to the customer. Performance obligations are promises in a contract to transfer a distinct good or service to the customer that (i) the customer can benefit from on its own or together with other readily available resources, and (ii) is separately identifiable from other promises in the contract. Goods or services that arenot* individually distinct performance obligations are combined with other promised goods or services until such combined group of promises meet the requirements of a performance obligation.

The Company determines transaction price based on the amount of consideration the Company expects to receive for transferring the promised goods or services in the contract. Consideration* maybe fixed, variable, or a combination of both. At contract inception for arrangements that include variable consideration, the Company estimates the probability and extent of consideration it expects to receive under the contract utilizing either the most likely amount method or expected amount method, whichever best estimates the amount expected to be received. The Company then considers any constraints on the variable consideration and includes in the transaction price variable consideration to the extent it is deemed probable that a significant reversal in the amount of cumulative revenue recognized willnot* occur when the uncertainty associated with the variable consideration is subsequently resolved.

The Company then allocates the transaction price to each performance obligation based on the relative standalone selling price and recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) control is transferred to the customer and the performance obligation is satisfied. For performance obligations which consist of licenses and other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

The Company records amounts as accounts receivable when the right to consideration is deemed unconditional. When consideration is received, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a contract, a contract liability is recorded as deferred revenue.

The Company’s revenue arrangements* may*include the following:

Milestone Payments: At the inception of an agreement that includes milestone payments, the Company evaluates each milestone to determine when and how much of the milestone to include in the transaction price. The Companyfirst estimates the amount of the milestone payment that the Company could receive using either the expected value or the most likely amount approach. The Company primarily uses the most likely amount approach as that approach is generally most predictive for milestone payments with a binary outcome. Then, the Company considers whether any portion of that estimated amount is subject to the variable consideration constraint (that is, whether it is probable that a significant reversal of cumulative revenue wouldnot occur upon resolution of the uncertainty.) The Company updates the estimate of variable consideration included in the transaction price at each reporting date which includes updating the assessment of the likely amount of consideration and the application of the constraint to reflect current facts and circumstances.

10

Royalties: For arrangements that include sales-based royalties, including milestone payments based on a level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).

Research Services: The Company incurred research costs in association with the License Agreement. After the First Milestone Payment (as defined in Note6 below), the Company would have been reimbursed for certain costs incurred related to reasonable and documented out-of-pocket costs for clinical and non-clinical development activities. The Company would have recognized revenue for the reimbursed costs when the First Milestone Payment contingencies had been achieved and the Company had an enforceable claim to the reimbursed costs.

Research and Development Costs

Research and development expense consists primarily of costs associated with the Company’s clinical trials, salaries, payroll taxes, employee benefits, and stock-based compensation charges for those individuals involved in ongoing research and development efforts. Research and development costs are expensed as incurred. Advance payments for goods and services that will be used in future research and development activities are recorded as prepaid assets and expensed when the activity has been performed or when the goods have been received.

Non-cancellable Contracts

The Company* mayrecord certain obligations as liabilities related to non-cancellable contracts. If appropriate, the offsetting costs may*be recorded as a deferred cost asset.

Convertible Notes Payable and Fair Value Election

As permitted under FASB ASC Topic825, Financial Instruments (“ASC825**”), the Company elected to account for its promissory notes, which meet the required criteria, at fair value at inception. Subsequent changes in fair value are recorded as a component of non-operating loss in the consolidated statements of operations. The portion of total changes in fair value of the notes attributable to changes in instrument-specific credit risk are determined through specific measurement of periodic changes in the discount rate assumption exclusive of base market changes and are presented as a component of comprehensive income in the accompanying condensed consolidated statements of operations and comprehensive loss. As a result of electing the fair value option, direct costs and fees related to the promissory notes are expensed as incurred.

The Company estimates the fair value of its notes payable using a Monte Carlo simulation model, which uses as inputs the fair value of its Common Stock and estimates for the equity volatility of its Common Stock, the time to expiration (i.e., expected term) of the note, the risk-free interest rate for a period that approximates the time to expiration, and probability of default. Therefore, the Company estimates its expected future equity volatility based on the historical volatility of its Common Stock price utilizing a lookback period consistent with the time to expiration. The time to expiration is based on the contractual maturity date, giving consideration to the redemption features embedded in the notes. The risk-free interest rate is determined based on the U.S. Treasury yield curve in effect at the time of measurement for time periods approximately equal to the time to expiration. Unless otherwise specified, the probability of default is estimated using Bloomberg’s Default Risk function which uses its financial information to calculate a default risk specific to the Company. At* September 30, 2024,*the Streeterville Note valuation was adjusted to the post settlement amount agreed upon. Interest expense is included within the fair value of the note payable. Management believes those assumptions are reasonable but if these assumptions change, it could materially affect the fair value.

11

Stock-Based Compensation

The Company expenses stock-based compensation to employees and non-employees over the requisite service period based on the estimated grant-date fair value of the awards. The Company accounts for forfeitures as they occur. Stock-based awards with graded-vesting schedules are recognized on a straight-line basis over the requisite service period for each separately vesting portion of the award. The Company estimates the fair value of stock option grants using the Black-Scholes option pricing model, and the assumptions used in calculating the fair value of stock-based awards represent management’s best estimates and involve inherent uncertainties and the application of management’s judgment. The Company estimates the fair value of restricted stock award grants using the closing trading price of the Company’s Common Stock on the date of issuance. All stock-based compensation costs are recorded in general and administrative or research and development costs in the condensed consolidated statements of operations and comprehensive loss based upon the underlying individual’s role at the Company.

Warrants

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in FASB ASC Topic480, Distinguishing Liabilities from Equity (“ASC480**”) and FASB ASC Topic815, Derivatives and Hedging (“ASC815**”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC480, meet the definition of a liability pursuant to ASC480, and whether the warrants meet all of the requirements for equity classification under ASC815, including whether the warrants are indexed to the Company’s own Common Stock and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that donot meet all the criteria for equity classification, the warrants are required to be liability classified and recorded at their initial fair value on the date of issuance and remeasured at fair value and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the statements of operations. The Company generally determines fair value of the Common Stock Warrants (as defined below) using a Black Scholes valuation methodology.

A change in any of the terms or conditions of warrants is accounted for as a modification. The accounting for incremental fair value of warrants is based on the specific facts and circumstances related to the modification which* may*result in a reduction of additional paid-in capital, recognition of costs for services rendered, or recognized as a deemed dividend.

Preferred Stock

In accordance with ASC480, the Company’s Series A Preferred Stock was classified as permanent equity as it wasnot mandatorily redeemable upon an event that is considered outside of the Company’s control. Further, in accordance with ASC815-40, Derivatives and Hedging–* Contracts in an Entity*’s Own Equity, the Series A Preferred Stock didnot meet any of the criteria that would preclude equity classification. The Company concluded that the Series A Preferred Stock was more akin to an equity-type instrument than a debt-type instrument, therefore the conversion features associated with the convertible preferred stock were deemed to be clearly and closely related to the host instrument and werenot bifurcated as a derivative under ASC815.

12

Income Taxes

Income taxes are recorded in accordance with FASB ASC Topic740, Income Taxes (“ASC740**”), which provides for deferred taxes using an asset and liability approach. The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are provided, if based upon the weight of available evidence, it is more likely thannot that some or all of the deferred tax assets willnot be realized. The Company accounts for uncertain tax positions in accordance with the provisions of ASC740. When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit would more likely thannot be realized assuming examination by the taxing authority. The determination as to whether the tax benefit will more likely thannot be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. The Company recognizes any interest and penalties accrued related to unrecognized tax benefits as income tax expense.

Loss Per Share

The Company applies thetwo-class method when computing net income or loss per share attributable to common stockholders. In determining net income or loss attributable to common stockholders, thetwo-class method requires income or loss allocable to participating securities for the period to be allocated between common and participating securities based on their respective rights to share in the earnings as if all of the income or loss allocable for the period had been distributed. In periods of net loss, there isno allocation required under thetwo-class method as the participating securities donot have an obligation to fund the losses of the Company.

Basic loss per share of Common Stock is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of Common Stock outstanding for the period. Diluted loss per share reflects the potential dilution that could occur if stock options, restricted stock awards and warrants were to vest and be exercised. Diluted earnings per share excludes, when applicable, the potential impact of stock options, Common Stock warrant shares, convertible notes, and other dilutive instruments because their effect would be anti-dilutive in the periods in which the Company incurs a net loss.

The following outstanding shares of Common Stock equivalents were excluded from the computation of the diluted net loss per share attributable to Common Stock for the periods in which a net loss is presented because their effect would have been anti-dilutive.

Recent Accounting PronouncementsNot Yet Adopted**

In* November 2023,the FASB issued Accounting Standard Update (ASU)No. 2023‑07, Segment Reporting (Topic280*)-Improvements to Reportable Segment Disclosures (ASU2023*-07), which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU2023*-07 should be applied on a retrospective basis. ASU2023-07 is effective for annual periods beginning after* December 15, 2023,and interim periods within fiscal years beginning after December 15, 2024.*Early adoption is permitted. The Company is in the process of evaluating the impact of this new guidance on its disclosures.

In* December 2023,the FASB issued ASU2023*-09-Income Taxes (Topic740): Improvements to Income Tax Disclosures (ASU2023*-09), which is intended to enhance the transparency and decision usefulness of income tax disclosures, primarily by amending disclosure requirements for the effective tax rate reconciliation and income taxes paid. ASU2023*-09 should be applied on a prospective basis, and retrospective application is permitted. ASU2023-09 is effective for annual periods beginning after* December 15, 2024.*Early adoption is permitted. The Company is in the process of evaluating the impact of this new guidance on its disclosures.

6. Alvogen Licensing Agreement

In* June2023,* the Company entered into a License Agreement with Alvogen. Under the License Agreement, the Company granted Alvogen certain license rights to develop, manufacture, and commercialize the Company’s candidate therapeutic product, NRX-101, for the treatment of bipolar depression with suicidality. In exchange for the license granted and the participation of the Company in certain development, regulatory and commercial activities, Alvogen was obligated to pay the Company specified regulatory and commercial milestones, thefirst of which was $9 million upon the later of a positive data read-out from the Company’s ongoing Phase2b/3 clinical trial and completion of the Type B meeting with the FDA (the “First Milestone Payment”). In* February 2024,the parties executed an amendment accelerating payment of up to $5 million related to the First Milestone Payment, with the remaining $4 million due upon the original agreement’s terms (see below for advances received through September30,* 2024). As compensation for advancing the milestone, Alvogen received warrants to purchase up to 419,598 shares of the Company's Common Stock, at a strike price of $4.00 with athree year term (See Note9). The grant date fair value of the warrants was approximately $1.3 million, which the Company planned to account for as consideration paid to a customer (see below). Thesecond portion of thefirst milestone was to be $4 million and, as before, triggered by a positive response to the Company's planned end of phase2 meeting with FDA. If thefirst milestone wasnot achieved by* September 3, 2024,the Company would have been obligated to repay any amount received against the $5 million advance of the First Milestone Payment to Alvogen. As there was significant uncertainty relative to approval of any drug candidate in development, the Company concluded that it wasnot* probable that a significant reversal of revenue wouldnot occur if the Company were to include the First Milestone Payment, or any advances thereof, in the transaction price prior to receiving FDA approval. Accordingly, the transaction price was fully constrained and advances from Alvogen were recorded as a refund liability until such time as the refund right expired. Further, the Company accounted for the warrants issued to Alvogen within additional paid-in capital consistent with the accounting for unfunded stock subscription agreements until such time as the uncertainty around the First Milestone was resolved.

Termination

Under the License Agreement, as amended, Alvogen was granted early termination rights. On* June 21, 2024,the Company received a notice of termination from Alvogen effective immediately. Following the termination of the License Agreement by Alvogen, the amounts advanced pursuant to the amendment became due and payable to Alvogen. Accordingly, the refund liability hasnot* been reclassified as deferred revenue or recorded as revenue as of* September**30,* 2024.

Upon termination of the License Agreement, the intellectual property rights licensed to Alvogen under the License Agreement reverted to the Company, and all other rights and obligations of each of the parties immediately ceased, except for outstanding amounts owed as of the time of such expiration or termination. As of* September30,* 2024, the refund liability due to Alvogen was $4.7 million, which represents all payments made by Alvogen through* September30,* 2024, and is included as a component of accrued expense and other current liabilities on the condensed consolidated balance sheet (refer to Note5). Following the early termination by Alvogen, the Company doesnot anticipate recognizing any revenue under the License Agreement. Additionally, in* June 2024*the Company wrote-off the unfunded stock subscription receivable of $1.3 million related to the warrants previously classified in additional paid-in capital to research and development expense following the termination.

7. Debt

Streeterville Convertible Note

On* November 4, 2022,*the Company issued an 9% redeemable promissory note (as amended, the “Streeterville**Note”) to Streeterville Capital, LLC, a Utah limited liability company (“Streeterville”), for an aggregate principal amount of $11.0 million. The Streeterville Note originally matured 18 months from the date of issuance subject to certain acceleration provisions. The Streeterville Note carried an original issue discount of $1.0 million which was deducted from the principal balance of the Streeterville Note. The net proceeds from the issuance of the Streeterville Note was $10.0 million after transaction costs including the original issue discount, legal and other fees are included.

The initial terms of the Streeterville Note included the following provisions, certain of which were subsequently modified, as described below. The Company had the option to prepay the Streeterville Note during the term by paying an amount equal to 110% of the principal, interest, and fees owed as of the prepayment date. The noteholder had the right to redeem up to $1.0 million of the outstanding balance of the Streeterville Note per month startingsix months after the issuance date (the “Maximum Monthly Redemption Amount”). Payments could be made by the Company at their option in: (i) in cash with a 10% premium (the “Redemption Premium”) for the amount redeemed, (ii) by paying the redemption amount in the form of shares of Common Stock with the number of redemption shares being equal to the portion of the applicable redemption amount divided by the Redemption Conversion Price (as defined below), or (iii) a combination of cash and shares of Common Stock. The “Redemption Conversion Price” on any given redemption date equaled 85% multiplied by the average of thetwo lowest daily volume weighted average prices per share of the Common Stock during theten trading days immediately preceding the date that the noteholder delivered notice electing to redeem a portion of the Streeterville Note. Beginning* May 1, 2023,in the event (a) the daily dollar trading volume of the Common Stock of the Company on any given trading day was at leastfifty* percent (50%) greater than the lower of (i) the median daily dollar trading volume over the previousten (10) trading days or (ii) the daily dollar trading volume on the trading day immediately preceding the date of measurement or (b) if the closing trade price on any given trading day was at leastthirty percent (30%) greater than the Nasdaq Minimum Price, then the lender would be entitled to redeem over the followingten (10) trading days an amount of indebtedness then outstanding under the Streeterville Note equal to twice the monthly redemption amount of $1.0 million solely by payment by stock, if permitted under the agreement, subject to the Maximum Percentage (as defined in the Streeterville Note) and other ownership limitations.

The Streeterville Note contained certain Trigger Events (as defined in the Streeterville Note) that generally, if uncured withinfive trading days, could result in an event of default in accordance with the terms of the Streeterville Note (such event, an “Event of Default”). Upon an Event of a Default, the Lender could consider the Streeterville Note immediately due and payable. Upon an Event of Default, the interest rate could also be increased to the lesser of 18% per annum or the maximum rate permitted under applicable law (see below).

Due to these embedded features within the Streeterville Note, the Company elected to account for the Streeterville Note at fair value at inception. Subsequent changes in fair value were recorded as a component of other income (loss) in the consolidated statements of operations.

Convertible Note Amendments

On* March 30, 2023,*the Company entered into an Amendment to the Note (the “First Amendment”), pursuant to which the Maximum Percentage was set at 9.99% of the number of shares of Common Stock outstanding on a given date.

On* July 7, 2023,the Company entered into Amendment#2* to the Streeterville Note with Streeterville (the “Second Amendment”). Pursuant to the Second Amendment, the Company agreed to amend the redemption provisions of the Streeterville Note to provide that the Company would pay to Streeterville an amount in cash equal to $1.8 million on or before* July 10, 2023,which amount was paid on July 10, 2023.In addition, the Company agreed that, beginning on or before July 31, 2023,and on or before the last day of each month until December 31, 2023,the Company would pay Streeterville an amount equal to $0.4 million in cash, less any amount satisfied by the delivery of Redemption Conversion Shares (as defined below). Notwithstanding the foregoing, Streeterville could also submit a request for redemption of up to an aggregate of $1.0 million per month in accordance with the terms of the Second Amendment. However, the portion of each payment that wasnot* satisfied by the delivery of Redemption Conversion Shares was the maximum amount of cash the Company would have been required to pay in accordance with the Second Amendment during the period from* July 31, 2023and on or before the last day of each month until December 31, 2023.*The redemption of the Maximum Monthly Redemption Amount in excess of the Minimum Amount would be satisfied by the delivery of additional Redemption Conversion Shares.

15

On* February 9, 2024,the Company entered into Amendment#3* to the Streeterville Note (the “Third Amendment”), with Streeterville. In accordance with the Third Amendment, the Company and Streeterville agreed to amend the redemption provisions of the Streeterville Note to provide that the Company would pay to Streeterville an amount in cash equal to $1.1 million on* February 12, 2024,which the amount was paid on February 12, 2024.In addition, beginning on or before February**29,* 2024, and on or before the last day of each month until* July 31, 2024,the Company was obligated to pay Streeterville an amount equal to $0.4 million in cash, less any amount satisfied by the delivery of Redemption Conversion Shares. During thefirst* three months of this amended payment period, Streeterville couldnot request to redeem amounts greater than $0.4 million per month.

After* April30,* 2024, and for the remainder of the payment period through* July 31, 2024,Streeterville could redeem any Redemption Amount (as defined in the Streeterville Note), including an amount in excess of the Minimum Payment, subject to the Maximum Monthly Redemption Amount. During the period through July 31, 2024,the Company was permitted to pay the Redemption Amounts by delivery of the Redemption Conversion Shares (as defined below) without regard to the existence of any Equity Conditions Failure, to the extent Streeterville submits redemption notices during such month pursuant to the terms of the Streeterville Note, and only for the Redemption Amounts covered by such notices. Moreover, the Redemption Premium would continue to apply to the Redemption Amounts. To the extent there was an outstanding balance under the Streeterville Note after July 31, 2024,the Company would be required to pay such outstanding balance in full in cash by August 31, 2024.As a result of the alleged Event of Default mentioned below, the Company didnot* pay any Redemption Amounts during thethree months ended* September30,* 2024, prior to the settlement, also as described below.

During the Minimum Payment Period (defined in the Streeterville Note, as amended), the Company was permitted to pay the Redemption Amounts in the form of shares of Common Stock of the Company (the “Redemption Conversion Shares”) calculated on the basis of the Redemption Conversion Price (as defined in the Streeterville Note) without regard to the existence of an Equity Conditions Failure. Moreover, the Redemption Premium (as defined in the Streeterville Note) would continue to apply to the Redemption Amounts.

Both the Second Amendment and the Third Amendment (considered cumulatively with the Second Amendment) were deemed to be debt modifications and didnot give rise to a debt extinguishment in accordance with FASB ASC Topic470, Debt, which was accounted for prospectively. The modification didnot result in recognition of a gain or loss in the consolidated statements of operations as the modifications werenot considered debt extinguishments, but impacted interest expense recognized in subsequent periods, prior to the settlement of the Streeterville Note.

Convertible Note Fair Value Measurements

The Company estimated the fair value of the Streeterville Note using a Monte Carlo simulation model, which used as inputs the fair value of its Common Stock and estimated for the equity volatility and volume volatility of its Common Stock, the time to expiration of the Streeterville Note, the risk-free interest rate for a period that approximated the time to expiration, and probability of default. Therefore, the Company estimated its expected future volatility based on the actual volatility of its Common Stock and historical volatility of its Common Stock utilizing a lookback period consistent with the time to expiration. The time to expiration was based on the contractual maturity date, giving consideration to the mandatory and potential accelerated redemptions beginningsix months from the issuance date. The risk-free interest rate was determined by reference to the U.S. Treasury yield curve in effect at the time of measurement for time periods approximately equal to the time to expiration. Probability of default was estimated using either Bloomberg's Default Risk function, which uses its financial information to calculate a default risk specific to the Company, or management's estimates which included, the Company's current cash runway, current efforts to raise financing, and current economic environment.

The discount to the principal amount was included in the carrying value of the Streeterville Note. During2022, the Company recorded a debt discount of approximately $1.0 million upon issuance of the Streeterville Note for the original issue discount of $1.0 million. As a result of electing the fair value option, any direct costs and fees related to the Streeterville Note were expensed as incurred. For thethree andnine months ended* September30,* 2024, the Company recorded a gain from the change in fair value of the Streeterville Note of $2.1 million and $1.8 million, respectively, which was recognized in other (income) expense on the condensed consolidated statements of operations as a result of the Company’s election of the fair value option. For thethree andnine months ended* September30,* 2023, the Company recorded a loss from the change in fair value of the Streeterville Note of $0.4 million and $2.8 million, respectively, which was recognized in other (income) expense on the condensed consolidated statements of operations as a result of the Company’s election of the fair value option.

During thethree andnine months ended* September 30, 2024*, the Company made cash payments for coupon interest on the Streeterville Note of approximately $0.4 million and $0.5 million, respectively, $0.2 million in cash of redemption premiums, made cash principal repayments of $2.1 million and $4.3 million, respectively, issued shares of Common Stock as coupon interest repayment of $0.1 million, issued shares of Common Stock as principal repayment of $0.3 million, and incurred a default penalty of $0.8 million. During thethree andnine months ended* September 30, 2023,the Company made cash payments for coupon interest on the Streeterville Note of approximately $0.5 million and $0.7 million, respectively, made cash principal repayments on the Streeterville Note of approximately $1.7 million and* $1.8 million, respectively, issued shares of Common Stock as interest repayment of $0.1 million and $0.1 million, respectively and issued shares of Common Stock as principal repayment of $0.9 million and $0.9 **million, respectively.

16

As of* September 30, 2024*, and* December 31, 2023*, the Streeterville Note carried a remaining balance of $3.0 million and $8.3 million, respectively. Refer to Note11 for the reconciliation of the fair values for the periods presented.

Alleged Default

On* April 24, 2024,the Company received written notice from counsel for Streeterville that an alleged event of default occurred with respect to the Streeterville Note issued by the Company in favor of Streeterville (the “Notice”). The Notice alleged that, among other things, (i) the announcement of the plan to partially spin-off of HOPE (the “Spin-Off”), constituted a “Fundamental Transaction” (as defined in the Streeterville Note) for which the Company failed to obtain Streeterville’s prior written consent before undertaking such transaction; and (ii) the Company failed to pay the Minimum Payment, as defined in the Streeterville Note, by April 8, 2024,following a Redemption Notice issued on April 3, 2024*by Streeterville to the Company, each of which resulted in the failure to cure a Trigger Event and subsequent Event of Default of the Streeterville Note, resulting in the acceleration of all of the outstanding amounts due thereunder.

Streeterville also filed a complaint (the “Complaint”) naming the Company as a defendant in the Third Judicial District Court of Salt Lake County, Utah. The Complaint was seeking, among other things: (i) declaratory relief for an order enjoining the Company from undertaking any Fundamental Transaction, including the Spin-Off, or otherwise issuing Common Stock or other equity securities (such as the shares of HOPE pursuant to the announced Spin-Off); and (ii) repayment of the Streeterville Note and other unspecified amounts of damages, costs and fees, butno less than $6.5 million, or the amounts currently outstanding under the Streeterville Note.

On* July 29, 2024,*in connection with the alleged Event of Default that Streeterville claimed occurred with respect to the Streeterville Note, the Company announced an order of the Utah arbitrator denying the petition of Streeterville to enjoin Spin-Off of 49% of shares in HOPE to current shareholders of the Company. The purpose of the proposed Spin-Off was to provide the Company’s shareholders with valuable consideration and to provide HOPE (currently a wholly-owned subsidiary) with a sufficient shareholder base to enable future listing on a national exchange. The arbitrator also denied Streeterville’s petition to enjoin the Company from selling additional shares of Common Stock to finance ongoing operations.

Streeterville Settlement

On* August 12, 2024,the Company and Streeterville entered into a Settlement and Release of Claims (the “Settlement Agreement”), whereby the Company and Streeterville agreed to settle all disputes between the parties and release the Company from all obligations arising from the Notes at certain Securities Purchase Agreement, dated November 4, 2022 (“Streeterville Notes”), between the Company and Streeterville, and that certain Convertible Promissory Note, dated November 4, 2022,issued to Streeterville by the Company, in exchange for a payment of $2.5 million upon the initial closing of the sale of the Anson Notes, and within60* days thereafter, asecond payment of $3.05 million. The Company made the $2.5 million payment upon the Anson Notes closing on* August 15, 2024.The Company made the $3.05 million payment in October 2024 (see Note14*).

The Company evaluated the terms of the Settlement Amendment in accordance with ASC470-50, Debt Modifications and Extinguishments. Both the Settlement Amendment and the Third Amendment (considered cumulatively with the Settlement Amendment) were deemed to be debt modifications and didnot give rise to a debt extinguishment in accordance with ASCTopic 470,** Debt, which will be accounted for prospectively. The modifications didnot result in recognition of a gain or loss in the consolidated statements of operations as the modifications werenot considered debt extinguishments, but will impact interest expense and the determination of fair value in future periods.

Anson Convertible Promissory Notes

On* August 12, 2024,*the Company entered into the Purchase Agreement with Investors. The Company agreed to sell, inthree equal tranches, original issue discount Anson Notes in the aggregate principal amount of up to approximately $16.3 million for an aggregate purchase price of up to approximately $15.0 million and warrants to purchase that amount of shares equal to 50% of the principal amount of the Notes divided by the VWAP of the Company’s Common Stock, as listed on the Nasdaq Capital Market, on the day prior to the closing of each respective tranche under the Anson Warrants.

In connection with the above offering, the Company engaged EF Hutton LLC as placement agent (the “Placement Agent”), Pursuant to the terms of the engagement with the Placement Agent, the Company will pay a cash fee of 7% of the gross proceeds the Company receives in the offering at closing.

2024 Senior Secured Convertible Promissory Notes

On* August 14, 2024,the Company entered into thefirst* tranche Senior Secured Convertible Note Agreements (the “First Tranche Notes”) with Anson Investment Master Fund LP and Anson East Master Fund LP (collectively “Anson”) at various amounts for an aggregate of $5.435 million subject to an original issuance discount of 8% or $485,000, less other cash issuance costs of $521,000, resulting in net cash proceeds of $4.5 million, prior to any allocation to the Anson Warrants. The First Tranche Notes bear interest at a rate of 6% per annum (or 10% during the occurrence of any Event of Default (as defined in the First Tranche Notes)) and have a term of 15 months from the issuance date, maturing on* November 14, 2025 (the “First Tranche Maturity Date”) (see Note9*).

On* August 14, 2024,*in conjunction with the issuance of the First Tranche Notes, the Company issued warrants to purchase up to 1,349,305 shares of the Company’s Common Stock.

The First Tranche Notes are convertible at the option of the holder at any time after issuance into Common Stock, at a per share conversion price equal to the lower of (a) $2.4168, (the “Fixed Conversion Price”) or (b) a price equal to 92% of the lowest VWAP during theseven trading day period immediately preceding the effective conversion date ((the “Alternate Conversion Price”, and together with the Fixed Conversion Price, the “Conversion Price”). If the Conversion Price is less than $0.38 (the “Floor Price”), then in addition to the issuance of Common Stock upon conversion the Company will pay cash as a true-up which is determined by the product of (i) the difference between (y) the Floor Price less (z) the Conversion Price then in effect, multiplied by (ii) the conversion amount that is being paid in Common Stock.

The terms of the First Tranche Notes donot allow any conversion of the First Tranche Notes if it results in Anson owning more than4.99% of the outstanding shares of Common Stock (the "Beneficial Ownership Limitation"). This limitation can be adjusted up to9.99% with prior notice, effective61 days after such notice. Anson must ensure compliance with this limitation when submitting a notice of conversion, and the Company will rely on Anson's representation of compliance.

If the Company issues or grants options for Common Stock at a price lower than the current Conversion Price, the Conversion Price will be adjusted to match this lower price, (the “Base Conversion Price”). The Company must notify Anson of any such issuance, and Anson is entitled to convert shares based on the new Base Conversion Price.

If the Company offers purchase rights to holders of Common Stock, Anson will be entitled to acquire those rights as if they had fully converted the Note, subject to the Beneficial Ownership Limitation. If exercising these rights would exceed the Beneficial Ownership Limitation, the rights will be held in abeyance until they can be exercised without exceeding the limit.

The First Tranche Notes contain mandatory redemption features, whereby if at any time the First Tranche Notes are outstanding, the Company will be required to: (A) use up to30% of the gross proceeds from any Subsequent Financings (as defined in the Purchase Agreement) in cash, to redeem all or a portion of the Note for an amount equal to the outstanding principal, plus all accrued but unpaid interest, plus all liquidated damages (the “Redemption Obligations”), multiplied by1.05 (the “Mandatory Redemption Amount”); (B) redeem all of the Redemption Obligations at the Mandatory Redemption Amount in the event of a Change of Control Transaction (as defined in the First Tranche Notes); (C) redeem the Redemption Obligations for the Mandatory Redemption Amount in the event a registration statement isnot available for each of the offer and resale of the shares issuable upon conversion of the First Tranche Notes (the “Conversion Shares”); and (D) redeem the Redemption Obligations for the Mandatory Redemption Amount if the Shareholder Approval isnot obtained within180 days following the date of issuance of the First Tranche Notes.

The First Tranche Notes contain certain covenants, and events of default and triggering events, respectively, which would require repayment of the obligations outstanding pursuant to such instruments. The obligations of the Company pursuant to the First Tranche Notes are (i) secured by all assets of the Company and all subsidiaries of the Company pursuant to the Security Agreement and Patent Security Agreement, dated* August 14, 2024,by and among the Company, the subsidiaries of the Company, and the Investors, and (ii) guaranteed jointly and severally by the subsidiaries of the Company pursuant to the Subsidiary Guarantee, dated August 14, 2024,*by and among the Company, the subsidiaries of the Company, and the Investors.

Due to these embedded features within the First Tranche Notes, the Company elected to account for the First Tranche Notes at fair value at inception. Subsequent changes in fair value are recorded as a component of other income (loss) in the condensed consolidated statements of operations. Additionally the portion of changes in the fair value related to changes in credit risk are recorded to other comprehensive income in the consolidated statements of operations. To determine the initial carrying value of the Notes and the warrants issued to Anson under the First Tranche Notes (see Note9), the Company allocated the proceeds using the relative fair value method. After allocation, the initial carrying value of the First Tranche Notes and the warrants issued to Anson were $2.9 million and $2.1 million, respectively. Refer to Note11 for the reconciliation of the fair values for the periods presented.

During thethree andnine months ended* September 30, 2024* Anson converted $0.7 million of principal and interest into Common Stock, resulting in the issuances of 458,553 shares of Common Stock and loss on redemption of $0.1 million. As of* September 30, 2024*, the principal and accrued interest balance of the First Tranche Note was $4.7 million and less than $0.1 million, respectively. During thethree andnine months ended* September 30, 2024,the Company recorded a loss from the change in fair value of the First Tranche Notes of $0.7 million and $0.7 million, respectively, which was recognized in other (income) expense on the condensed consolidated statements of operations as a result of the Company’s election of the fair value option. At September 30, 2024* the effective interest rate of the First Tranche Note was 69.3%.

As these Substitute Warrants meet the definition of a derivative as contemplated in FASB ASC Topic815, based on provisions in the warrant agreement related to the Earnout Shares Milestone and the Earnout Cash Milestone and the contingent right to receive additional shares for these provisions, the Substitute Warrants were recorded as derivative liabilities on the consolidated balance sheet and measured at fair value at inception (on the date of the Merger) and at each reporting date in accordance with FASB ASC Topic820, with changes in fair value recognized in the statements of operations in the period of change.

The Company recognized a gain on the change in fair value of the Substitute Warrants for thethree months ended* September 30, 2024and2023* of $0 and less than $0.1 million, respectively. The Company recognized a gain on the change in fair value of the Substitute Warrants for thenine months ended* September 30, 2024and2023* of less than $0.1 million and less than $0.1 million, respectively. Refer to Note11 for further discussion of fair value measurement of the warrant liabilities.

Assumed Public Warrants

Prior to the Merger, the Company had 3,450,000 warrants outstanding (the “Public Warrants”) to purchase up to 345,000 shares of Common Stock. Each Public Warrant entitles the holder to purchaseone-tenth share of Common Stock at an exercise price of $115 per share. The Public Warrants became exercisable at the effective time of the Merger and expirefive years after the effective time on or earlier upon their redemption or liquidation of the Company.

During thethree andnine months ended* September 30, 2024and2023* no Public Warrants were exercised. The outstanding balance of these public warrants remains in equity. At* September 30, 2024* and* December 31, 2023*, there were 3,448,856 Public Warrants outstanding to purchase up to 344,886 shares of Common Stock.

Assumed Private Placement Warrants

Prior to the Merger, the Company had outstanding 136,250 Private Placement Warrants (the “Private Placement Warrants”) to purchase up to 13,625 shares of Common Stock. The Private Placement Warrants arenot indexed to the Company’s common shares in the manner contemplated by FASB ASC Topic815-40-15 because the holder of the instrument isnot an input into the pricing of a fixed-for-fixed option on equity shares. The Company classifies the Private Placement Warrants as derivative liabilities in its condensed consolidated balance sheets as of* September 30, 2024* and* December 31, 2023*. The Company measures the fair value of the Private Placement Warrants at the end of each reporting period and recognizes changes in the fair value from the prior period in the Company’s statements of operations for the current period.

The Company recognized a gain on the change in fair value of the Private Placement Warrants for thethree months ended* September 30, 2024and2023* of less than $0.1 million and less than $0.1 million, respectively. The Company recognized a gain on the change in fair value of the Private Placement Warrants for thenine months ended* September 30, 2024and2023* of less than $0.1 million and less than $0.1 million, respectively. Refer to Note11 for discussion of the fair value measurement of the Company’s warrant liabilities.

On* March 5, 2024the Company issued Underwriter’s Warrant to purchase up to 3,750 shares of Common Stock in relation to the exercise of the February*Over-Allotment Option. The measurement of fair value was determined utilizing a Black-Scholes model considering all relevant assumptions current at the date of issuance (i.e., share price of $3.05, exercise price of $3.30, term of 5 years, volatility of 178.10%, risk-free rate of 4.12%, and expected dividend rate of 0%). The allocated fair value of the Underwriter's Warrants on the grant date was less than $0.1 million and is recorded as a charge to additional paid-in capital.

Anson Warrants

The Anson Warrants, originally issued in the Purchase Agreement, are recognized as derivative liabilities in accordance with ASC815. The Company concluded liability classification was appropriate as certain settlement features included in the Anson Warrants arenot indexed to the Company's own stock, and therefore preclude equity classification. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercise or expiration, and any change in fair value is recognized in the Company’s condensed consolidated statements of operations. The Anson Warrants were initially measured at fair value using a Black-Scholes model and have subsequently been measured based on the listed market price of such warrants. Warrant liabilities are classified as current liabilities on the Company's condensed consolidated balance sheets. On* August 14, 2024,in conjunction with the issuance of the First Tranche Notes, the Company issued warrants to purchase up to 1,349,305 shares of the Company’s Common Stock which were classified as a liability. The warrants have an exercise price of $2.4168 per share and have a contractual term offive years expiring on August 14, 2029.The measurement of fair value of the Investor Warrants were determined utilizing a Black-Scholes model considering all relevant assumptions current at the date of issuance (i.e., share price of $1.86, exercise price of $2.42, term offive years, volatility of 122%, and risk-free rate of 3.67%, and expected dividend rate of 0%). The grant date fair value of these Investor Warrants was estimated to be $2.1 million on August 14, 2024.As of September 30, 2023,the fair value of the Anson Warrants was $1.9 million. Refer to Note11* for further discussion of fair value measurement of the warrant liabilities.

10. Stock-Based Compensation

2016 Omnibus Incentive Plan

Prior to the Merger, NRx maintained its2016 Omnibus Incentive Plan (the “2016 Plan”), under which NeuroRx granted incentive stock options, restricted stock awards, other stock-based awards, or other cash-based awards to employees, directors, and non-employee consultants. The maximum aggregate shares of Common Stock that were subject to awards and issuable under the2016 Plan was 347,200.

In connection with the Merger, each option of NeuroRx that was outstanding and unexercised immediately prior to the Effective Time (whether vested or unvested) was assumed by BRPA and converted into an option to acquire an adjusted number of shares of Common Stock at an adjusted exercise price per share, based on the Exchange Ratio (of 0.316:1).

Upon the closing of the Merger, the outstanding and unexercised NeuroRx stock options became options to purchase an aggregate 289,542 shares of the Company’s Common Stock at an average exercise price of $51.00 per share.

2021 Omnibus Incentive Plan

As of* September 30, 2024*,955,281 shares of Common Stock are authorized for issuance pursuant to awards under the Company’s2021 Omnibus Incentive Plan (the “2021 Plan”). As of* January 1,2024,83,920 shares were added to the2021 Plan under an evergreen feature that automatically increases the reserve with additional shares of Common Stock for future issuance under the Incentive Plan each calendar year, beginning January 1, 2022and ending on and including January 1, 2031,equal to the lesser of (A)1% of the shares of Common Stock outstanding on the final day of the immediately preceding calendar year or (B) a smaller number of shares determined by the Board. On December 28, 2023thefirst* amendment to the2021 Omnibus Plan was executed which increased the maximum number of shares (i) available for issuance under the Plan, by an additional 200,000 shares, and (ii) that* maybe delivered pursuant to the exercise of Incentive Stock Options granted under the Plan to be equal to100%* of the Share Pool. As of* September 30, 2024*, an aggregate 585,099 shares have been awarded net of forfeitures, and 370,182 shares remain available for issuance under the2021 Plan. The2021 Plan permits the granting of incentive stock options, restricted stock awards, other stock-based awards or other cash-based awards to employees, directors, and non-employee consultants.

Option Awards

The fair value of each employee and non-employee stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. The Company is a public company and has limited company-specific historical and implied volatility information. Therefore, it estimates its expected stock volatility based on the limited company-specific historical volatility and implied volatility. The expected term of the Company’s stock options for employees has been determined utilizing the “simplified” method for awards. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve. Expected dividend yield iszero based on the fact that the Company has never paid cash dividends and doesnot expect to pay any cash dividends in the foreseeable future. Additionally, certain options granted contain terms that require all unvested options to immediately vest a) upon the approval of an NDA by the FDA forNRX‑101, or b) immediately preceding a change in control of the Company, whichever occurs first.

The Company issuedno stock options during thethree ornine months ended* September 30, 2024*.

21

The following table summarizes the Company’s employee and non-employee stock option activity under the2021 Plan for the following periods:

Stock-based compensation expense related to stock options was $0.1 million and $0.4 million for thethree andnine months ended* September 30, 2024*, respectively.

At* September 30, 2024*, the total unrecognized compensation related to unvested employee and non-employee stock option awards granted, was $0.1 million, which the Company expects to recognize over a weighted-average period of approximately 0.9 years.

Restricted Stock Awards

The following table presents the Company’s Restricted Stock Activity:

On* July 12, 2022,the Board granted an award of 100,000 restricted shares of the Company (“RSAs”) as an inducement to the newly appointed CEO, pursuant to a separate Restricted Stock Award Agreement. The RSAs will vest in approximately equal installments overthree* (3) years from the grant date, subject to continued service through the applicable vesting date.

On* December 28, 2023,the Company was authorized to grant 57,500 RSAs to a consultant for services provided. The RSAs vested aftersix months from September 4, 2023,*the date the services began. The shares were valued on the grant date based on the quoted price of $4.60 or approximately $0.3 million which was amortized over the vesting term.

Stock-based compensation expense related to RSAs was less than $0.1 million for thethree andnine months ended* September 30, 2024* respectively.

Subsequent to* September 30, 2024,the Company's CEO announced his resignation and as a result, all unvested RSAs were forfeited. Accordingly, the Company doesnot expect to recognize any further stock-based compensation expense for the balance of unvested RSAs as of September 30, 2024.*

11. Fair Value Measurements

Fair value measurements discussed herein are based upon certain market assumptions and pertinent information available to management as of and during thethree andnine months ended* September 30, 2024and2023*. The carrying amount of accounts payable approximated fair value as they are short term in nature. The fair value of stock options and warrants issued for services are estimated based on the Black-Scholes model. The fair value of the convertible notes payable was estimated utilizing a Monte Carlo simulation.

Fair Value on a Recurring Basis

The Company follows the guidance in ASC820 for its financial assets and liabilities that are re-measured and reported at fair value at each reporting period, and non-financial assets and liabilities that are re-measured and reported at fair value at least annually. The estimated fair value of the money market account represents a Level1 measurement. The estimated fair value of the warrant liabilities and convertible note payable represent Level3 measurements. The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis at* September 30, 2024* and* December 31, 2023*, and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value (in thousands):

Convertible Note Payable - Streeterville

The significant inputs used in the Monte Carlo simulation to measure the Streeterville note liability that is categorized within Level3 of the fair value hierarchy are as follows:

As of September 30, 2024,*the fair value was determined to be $3.1 million, reflecting the remaining obligation post-settlement. Given the short interval between the valuation dates, the impact on the fair value was deemed immaterial.

23

The following table sets forth a summary of the changes in the fair value of the Streeterville Note categorized within Level3 of the fair value hierarchy (in thousands):

Convertible Note Payable - Anson

The significant inputs used in the Monte Carlo simulation to measure the Anson note liability that is categorized within Level3 of the fair value hierarchy are as follows:

The following table sets forth a summary of the changes in the fair value of the Anson Note categorized within Level3 of the fair value hierarchy (in thousands):

Warrant Liabilities

The Company utilizes a Black-Scholes model approach to value its liability-classified warrants at each reporting period, with changes in fair value recognized in the consolidated statements of operations. The estimated fair value of the warrant liabilities is determined using Level3 inputs. There wereno transfers between levels within the fair value hierarchy during the periods presented. Inherent in a Black Scholes options pricing model are assumptions related to expected share-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its Common Stock based on historical volatility that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasuryzero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero.

The weighted-average significant inputs used in the Black-Scholes model to measure the warrant liabilities that are categorized within Level3 of the fair value hierarchy are as follows:

A reconciliation of warrant liabilities is included below (in thousands):

12. Income Taxes

The Company recordedno provision or benefit for income tax expense for thenine months ended* September 30, 2024and2023*, respectively.

For all periods presented, the pretax losses incurred by the Company receivedno corresponding tax benefit because the Company concluded that it is more likely thannot that the Company will be unable to realize the value of any resulting deferred tax assets. The Company will continue to assess its position in future periods to determine if it is appropriate to reduce a portion of its valuation allowance in the future.

The Company hasno open tax audits with any taxing authority as of* September 30, 2024*.
