Note 1. Organization

The Business

NRx Pharmaceuticals, Inc. (Nasdaq: NRXP) (“NRx”, the “Company”, “we”, “us” or “our”) is a clinical-stage bio-pharmaceutical company which develops and will distribute, through its wholly-owned operating subsidiary, NeuroRx, Inc., (“NeuroRx”), novel therapeutics for the treatment of central nervous system disorders including suicidal depression, chronic pain, post-traumatic stress disorder (“PTSD”) and schizophrenia. NRx is additionally the founder and majority owner of HOPE Therapeutics, Inc. (“HOPE”), a medical services company that offers interventional psychiatry care to patients with treatment-resistant depression and PTSD with a combination of neuroplastic drugs, transcranial magnetic stimulation (“TMS”), digital therapeutics, and hyperbaric therapy. All of our current drug development activities are focused on drugs that enhance “neuroplasticity” (growth of new brain connections) by modulating 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. The Company hastwo lead drug candidates – NRX-100, a preservative-free formulation of ketamine for intravenous infusion, and NRX-101, an oral fixed dose combination of D-cycloserine (“DCS”) and lurasidone. NRX-100 and NRX-101 are in the process of submission for Food and Drug Administration (“FDA”) approval as follows:

As previously announced, in* February 2024,*NRx incorporated HOPE Therapeutics, a medical care delivery organization focused on providing cutting-edge, comprehensive interventional psychiatric treatment with the most effective treatments available, including NMDA-targeted and other neuroplastic drugs, such as ketamine, Spravato and NRX-101, neuromodulatory devices, such as TMS, hyperbaric therapy, digital therapeutics, and medication management.

On* December 2, 2024,*HOPE formed HTX Management Company, LLC, a wholly owned subsidiary organized as a Delaware limited liability company, for the purpose of supporting future back end operations associated with the growing network of HOPE clinics.

On* September 8, 2025,HOPE became a revenue-generating clinical enterprise through its completion of the previously announced acquisition of Dura Medical, LLC (“Dura”), a Florida limited liability company, and a revenue-generating clinical organization with locations in Naples and Ft. Myers, Florida. Founded in2018,* Dura offers precision-based interventional psychiatry services, including ketamine infusion therapy, TMS, Spravato®, stellate ganglion blocks, and psychotherapy (See Note17).

Subsequent to thethird quarter, the Company completed the previously announced addition of Cohen and Associates, based in Sarasota, FL, to the HOPE Network with a strategic minority investment, which expanded HOPE’s footprint on the West Coast of Florida, and related appointment of Dr. Rebecca Cohen as HOPE’s Medical Director. On* November 10, 2025,HOPE announced completion of clinical training on the Ampa Health TMS device and initiation of the ONE-D protocol at its Florida locations. The ONE-D protocol has been reported in the peer-reviewed literature to achieve87%* response and72% remission from severe depression at6 weeks following a single day of TMS treatment, combined with D-cycloserine. HOPE is thefirst clinical enterprise to offer thisone-day treatment protocol in Florida andone of thefirst to offer this therapy nationwide.

Note2. Going Concern

The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the ordinary course of business. Since inception, the Company has incurred recurring operating losses and negative cash flows from operations. For thenine months ended* September 30, 2025,the Company reported a net loss of approximately $29.0 million, used cash in operations of approximately $10.4 million, had an accumulated deficit of approximately $307.3 million. As of September 30, 2025,*the Company had cash and cash equivalents of $7.2 million and a working capital deficit of $28.6 million.

The Company generated initial patient service revenue of approximately $0.2 million during the quarter ended* September 30, 2025,following the acquisition of Dura on September 8, 2025.Management expects to continue incurring operating losses through at least the remainder of2025* as it integrates Dura and pursues additional acquisitions through its HOPE subsidiary. While management projects incremental revenue from clinical operations and, upon regulatory approval, from pharmaceutical product sales, these projections are subject to significant uncertainty, including successful completion of pending acquisitions and receipt of FDA approval for NRX-100 and NRX-101.

As of* September 30, 2025,the Company had $7.2 million in cash and cash equivalents. On January 27, 2025,the Company entered into a securities purchase agreement (the “First RD Purchase Agreement”) with the investors for the sale by the Company of 1,215,278 shares (the “First RD Shares”) of Common Stock to the investors, at a purchase price of $2.88 per share, in a registered direct offering (the “First Registered Direct Offering”). The closing of the sales of these securities under the First RD Purchase Agreement occurred on or about January 29, 2025 (the “First RD Closing Date”), resulting in net proceeds to the Company of approximately $3.255 million after transaction costs. Concurrently with the sale of the First RD Shares, pursuant to the First RD Purchase Agreement the Company also sold to the investors unregistered Common Stock purchase warrants (the “First RD Warrants”) to purchase up to an aggregate of 1,215,278 shares of Common Stock (the “First RD Warrant Shares”), in a private placement. Subject to certain beneficial ownership limitations, the RD Warrants are immediately exercisable upon issuance at an exercise price equal to $2.88 per share of Common Stock, subject to adjustments as provided under the terms of the RD Warrants and are exercisable forfive* years from the First RD Closing Date.

On* August 18, 2025,the Company entered into a securities purchase agreement (the “Second RD Purchase Agreement”) with certain accredited investors for the sale of an aggregate of 3,959,999 shares of the Company’s Common Stock, at a purchase price of $1.65 per share (the “Second Registered Direct Offering”). The Second Registered Direct Offering closed on August 18, 2025,and resulted in net proceeds of approximately $6.2 million, after deducting placement agent fees and other offering-related expenses of approximately $0.3 million. Concurrently with the execution of the Second RD Purchase Agreement, the purchasers of the Second Registered Direct Offering entered into Lock-Up Agreements with the Company, pursuant to which they agreednot* to sell, transfer, or otherwise dispose of the shares of Common Stock, subject to certain exceptions, without the prior written consent of the Company until* August 19, 2026.*

Pursuant to the purchase agreement (the “Anson Purchase Agreement”) with Anson Investment Master Fund LP and Anson East Master Fund LP (collectively “Anson”), on* January 28, 2025 (the “Third Closing Date”), the Company sold a total of $5.4 million in Notes (as defined below) subject to an original issue discount of 8% or $0.435 million less other issuance costs of $0.4 million noted below (the “Third Tranche Notes” and collectively with the First Tranche Notes and Second Tranche Notes, the (“Anson Notes”)), with an aggregate purchase price of approximately $5.0 million, and warrants to purchase up to 862,699 shares of Common Stock. The Company intends to use the net proceeds from these transactions for general corporate purposes, including the funding of certain capital expenditures (See Note10* and12).

On* September 30, 2025,1,870,960 shares underlying Anson Warrants were exercised for cash proceeds of $3.09 million. Because the exercise proceeds were received subsequent to September 30, 2025,the Company recorded a subscription receivable asset of $3.09 million as of September 30, 2025.The exercise proceeds of $3.09 million were received on October 1, 2025.*

On* April 17, 2025,the Company reinstated its at-the-market offering and increased the maximum aggregate offering amount and filed a prospectus supplement under the offering agreement for an aggregate of $20,000,000. During thethree* months ended* September 30, 2025,the Company sold an aggregate of 1,350,788 shares of Common Stock for approximately $3.81 million, net of less than $0.1 million in offered costs. During thenine* months ended* September 30, 2025,the Company sold an aggregate of 1,749,866 shares of Common Stock for approximately $4.85 million, net of $0.1 million in offering costs. For more information regarding the Company’s at-the-market offering, please see Note12,* “Equity,” of these unaudited condensed consolidated quarterly financial statements.

The Company has secured operating capital that it anticipates as sufficient to fund its drug development operations through at least thesecond quarter of2026 and to finance submission of FDA NDAs for NRX-100 and NRX-101. The Company additionally expects to continue to accrue revenue from clinical operations. The Company* maypursue additional equity or debt financing or refinancing opportunities in2025* and2026 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 stockholders. 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 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 accompanying condensed 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.

Note3. Summary of Significant Accounting Policies

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 condensed 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.

The condensed consolidated financial statements include the accounts of NRx Pharmaceuticals, Inc. and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

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 condensed 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 allowance for credit losses on accounts receivable, fair value of the convertible notes payable, fair value of warrant liabilities, fair value of stock options and warrants, fair value of the Common Stock shares granted for services, fair value of the purchase price and the assets acquired and liabilities assumed in business combinations, the fair value of intangible assets and goodwill, the fair value of lease liabilities and related right of use assets, 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.

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 Note14)

Business Acquisition

The Company recognizes and measures identifiable tangible and intangible assets acquired and liabilities assumed as of the acquisition date at fair value. Fair value measurements require extensive use of estimates and assumptions, including estimates of future cash flows to be generated by the acquired assets. The operating results of the acquired business are included in our unaudited condensed consolidated financial statements beginning on the date of acquisition. The purchase price is equivalent to the fair value of consideration transferred. Goodwill is recognized for the excess of purchase price over the net fair value of assets acquired and liabilities assumed. Acquisition-related costs are expensed as incurred.

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, 2025,the Company’s cash and cash equivalents balance within money market accounts was in excess of the U.S. federally insured limits by $6.9 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.

Allowance for credit losses

Accounts receivable are recorded at the estimated transaction price (net of contractual adjustments, discounts, and implicit price concessions). The Company applies the Current Expected Credit Loss (“CECL”) model to estimate lifetime expected credit losses on trade receivables and contract assets, pooling receivables by payer type and aging and incorporating historical loss experience, current conditions, and reasonable‑and‑supportable forecasts with reversion to historical loss information beyond the forecast horizon. Receivables are written off when collection is deemed remote; recoveries are recognized when received. The Company doesnot have any off-balance sheet credit exposure related to its customers.

As part of the acquisition of Dura on* September 8, 2025,accounts receivable were recorded at fair value, which reflected expected collectability (see Note17* Business Combinations). Post-acquisition, the Company continues to apply the CECL model to estimate expected credit losses. The allowance for credit losses was $0.1 million as of* September 30, 2025and December 31, 2024,respectively. The company recorded a credit loss recovery of less than $0.1 million during thethree* andnine months ended* September 30, 2025.The Company believes that its reserve is adequate; however, actual results may*differ in future periods.

11

Intangible Assets

The Company’s intangible assets consist of customer relationships, trade name, and non-compete agreements. Customer relationships represents the value of established patient relationships and referral sources that are expected to generate recurring revenue streams. Trade name represents the value associated with the brand name in place at the date of the acquisition. Non-compete intangible assets represent the value associated with non-compete agreements for former employees and owners in place at the date of the acquisition. The customer relationships and trade name are being amortized over a 7-year term and10-year term, respectively, based on the estimated economic useful life of the customer relationships and trademark. The non-compete agreement is amortized over a 5-year term based on the estimated useful life of the asset. The amortization of the intangible asset is computed using the straight-line method.

The Company evaluates its definite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount* may**not* be recoverable. Such indicators* mayinclude adverse changes in market conditions, legal or regulatory developments, or underperformance relative to expectations. If indicators are present, the Company performs a recoverability test by comparing the asset’s carrying amount to the undiscounted future cash flows expected to result from its use and eventual disposition. If the carrying amount isnot* recoverable, an impairment loss is recognized for the excess of the carrying amount over the asset’s fair value.

Goodwill represents the excess of the cost of an acquired business over the fair value assigned to its net assets. Goodwill isnot amortized but is tested for impairment at a reporting unit level on an annual basis or when an event occurs, or circumstances change that would more likely thannot reduce the fair value of a reporting unit below its carrying amount. Events or changes in circumstances that* maytrigger interim impairment reviews include, butnot* limited to, significant adverse changes in business climate, operating results, planned investments in the reporting unit, or an expectation that the carrying amount* may**not* be recoverable, among other factors.

The Company* may**first* assess qualitative factors to determine whether it is more likely thannot that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events and circumstances, the Company determines it is more likely thannot that the fair value of the reporting unit is greater than its carrying amount, an impairment test is unnecessary. If an impairment test is necessary, the Company will estimate the fair value of its related reporting units. If the carrying value of a reporting unit exceeds its fair value, the goodwill of that reporting unit is determined to be impaired, and the Company will proceed with recording an impairment charge equal to the excess of the carrying value over the related fair value.

During thenine months ended* September 30, 2025,the Company recorded goodwill in connection with a business acquisition. In evaluating whether a triggering event occurred during the period, the Company performed a qualitative assessment consistent with the guidance in U.S. GAAP. This assessment considered the totality of events and circumstances, including the existence of substantial doubt to continue as a going concern, and concluded that it isnot* more likely thannot (i.e., less than a50% likelihood) that the fair value of the reporting unit is below its carrying amount. Based on this assessment, no impairment charges related to goodwill were recorded for the periods presented.

Furniture and Equipment, net

Furniture and equipment, net is stated at cost less accumulated depreciation. These assets are depreciated over their estimated useful lives offive toseven years using the straight-line method.

The Company adheres to ASC360 Property, Plant, and Equipment and periodically evaluates whether current facts or circumstances indicate that the carrying value of its depreciable assets to be held and used* may**not* be recoverable. If such circumstances are determined to exist, an estimate of undiscounted future cash flows produced by the long-lived assets, or the appropriate grouping of assets, is compared to the carrying value to determine whether impairment exists. If an asset is determined to be impaired, the loss is measured based on the difference between the asset’s fair value and its carrying value. For long-lived assets, the estimate of fair value is based on various valuation techniques, including a discounted value of estimated future cash flows. The Company reports an asset to be disposed of at the lower of its carrying value or its fair value less costs to sell. There wereno impairment losses for long-lived assets recorded for thethree andnine months ended* September 30, 2025and2024.*

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.

12

The License Agreement (the “License Agreement”) with Alvogen Pharma US, Inc., Alvogen, Inc., and Lotus Pharmaceutical Co. Ltd. (collectively, “Alvogen”) (as further discussed in Note9 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:

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 for 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.

13

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 Note9 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.

Patient Service Revenue: Patient service revenue is recognized as performance obligations are satisfied, which occurs over time as patients simultaneously receive and consume services. Each treatment or visit generally represents a separate contract. Procedural services (e.g., ketamine infusions, esketamine administration, TMS sessions, SGB/epidural procedures) are recognized at the point in time when rendered; therapy and medication management services are recognized as sessions occur. The transaction price includes variable consideration such as contractual adjustments, expected denials, and implicit price concessions, which are estimated and constrained to amountsnot expected to reverse. The Company applies the portfolio approach for contracts with similar characteristics by payer and service type. The Company elected the practical expedientnot to assess a significant financing component because the period between service and payment isone year or less. The Company acts as principal in its patient service arrangements and records revenue on a gross basis.

Patient service revenue is primarily derived from services rendered to patients for outpatient behavioral health care, interventional psychiatry, and pain management procedures. The Company’s services haveno fixed duration and can generally be terminated by the patient or the Company at any time; therefore, each treatment or visit is considered its own stand-alone contract.

The Company disaggregates Patient service revenue from contracts with customers by service type including procedural services and therapy services and by payor type including commercial insurance, Medicare, and self-pay. Management believes this presentation best reflects the nature, amount, timing, and uncertainty of the Company’s patient service revenue and cash flows.

Cost of Patient Services

Cost of patient services includes direct costs associated with providing healthcare services, such as salaries and benefits for clinical personnel, medical supplies, pharmaceuticals, and other costs directly attributable to patient care. These costs are expensed as incurred.

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 including interest and amortization of discounts are recorded as a component the change in fair value of convertible notes payable included in other expense (income) in the condensed 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 issuance of 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. Management believes those assumptions are reasonable but if these assumptions change, it could materially affect the fair value.

14

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 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.

Segment Information

The Company’s Chief Operating Decision Maker (“CODM”) is its Chief Executive Officer, who reviews financial information presented for purposes of making operating decisions, assessing financial performance, and allocating resources. The Company operates as a single operating and reportable segment, consistent with the manner in which the CODM evaluates performance and allocates resources, see Note15 for further information.

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.

Note4. Revenue and accounts receivable

Revenue for thethree andnine months ended* September 30, 2025is primarily derived from services rendered to patients for outpatient behavioral health care, interventional psychiatry, and pain management procedures. The Company’s services haveno* fixed duration and can generally be terminated by the patient or the Company at any time; therefore, each treatment or visit is considered its own stand-alone contract.

The Company disaggregates revenue from contracts with customers by service type and by payor, as management believes this best depicts the nature, amount, timing, and uncertainty of revenue and cash flows.

Revenue by Service Type (in thousands):

Revenue by payor (in thousands):

The Company receives payments from the following sources: (i) commercial insurers; (ii) the federal government under the Medicare program administered by the Centers for Medicare and Medicaid Services (“CMS”) and other programs; (iii) state governments under Medicaid and related programs; and (iv) individual patients and clients.

The Company determines the transaction price based on established billing rates reduced by contractual adjustments, discounts, and implicit price concessions, which represent amounts the Company doesnot expect to collect based on historical experience and other relevant factors. Contractual adjustments and discounts are based on contractual agreements with commercial insurance and Medicare, discount policies, and historical experience. Implicit price concessions are based on historical collection experience. Most of the Company’s services have contracts containing variable considerations, such as contractual adjustments, discounts, and implicit price concessions, which are estimated and reflected as reductions to revenue in the period the services are provided. However, it is unlikely a significant reversal of revenue will occur when the uncertainty is resolved, and therefore, the Company includes the variable consideration in the estimated transaction price. Subsequent changes resulting from a patient’s ability to pay are recorded as credit loss expense, which is included in other operating expenses. For thenine months ended* September 30, 2025,*current expected credit loss recovery was less than $0.01 million reflecting a net reversal of the allowance for credit losses following the acquisition of Dura.

The Company derives a significant portion of its revenue from Medicare, and other payors that receive discounts from established billing rates. The Medicare regulations and various managed care contracts under which these discounts must be estimated are complex, subject to interpretation and adjustment, and* may*include multiple reimbursement mechanisms for different types of services provided. Management estimates the transaction price on a payor specific basis given its interpretation of the applicable regulations or contract terms. The services authorized and provided and related reimbursement are often subject to interpretation that could result in payments that differ from the Company’s estimates.

Note7. Leases

Accounting for Leases as Lessee

The Company determines if an arrangement is a lease at inception. Operating leases are included in right-of-use assets (“ROU”), lease liabilities, and lease liabilities – related party. Lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date.None of the leases entered into have an implicit rate, the Company uses its incremental borrowing rate based on the information available at lease commencement date in determining the present value of future payments. Incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. The ROU assets also include any prepaid lease payments made and initial direct costs incurred and exclude lease incentives. The Company’s lease terms* mayinclude options to extend or terminate the lease, which is recognized when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Leases with an initial term of12* months or less arenot recorded on the balance sheet.

The Company has operating leases fortwo healthcare clinics in Naples and Fort Myers, Florida:

The components of lease expense included in the Company’s statement of operations were as follows (in thousands):

Other information related to leases is as follows:

Amounts relating to leases were presented on the balance sheet as of* September 30, 2025*in the following line items (in thousands):

Note9. Alvogen Licensing Agreement

In* June**2023,* the Company entered into a License Agreement with Alvogen. 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 to deferred revenue or recorded as revenue as of* September 30, 2025*and will remain permanent as refund liability until settled.

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* September 30, 2025,the refund liability due to Alvogen was $4.7 million, which represents all payments made by Alvogen through September 30, 2025,and is included as a component of accrued expense and other current liabilities on the condensed consolidated balance sheet (See Note8*). 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.

Note10. Debt

Streeterville Convertible Note

On* November 4, 2022,the Company issued a convertible note to Streeterville Capital, LLC (“Streeterville”), for an aggregate principal amount of $11.0 million (the “Streeterville Note”). The note was accounted for under the fair value option of ASC 825. All material terms of the Streeterville note have been disclosed in prior filings. As previously disclosed, on April 24, 2024,the Company received written notice from counsel for Streeterville that an alleged event of default occurred with respect to the Note issued by the Company in favor of Streeterville. 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 to Streeterville under the terms of the Streeterville Note 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 $3.1 million. The Company made the above payments as agreed, thereby consummating the settlement.

20

The Company evaluated the terms of the Settlement Agreement 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 condensed 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.

As of* September 30, 2025and December 31, 2024,the Streeterville Note carried a remaining principal balance of $0. See Note14* for the reconciliation of the fair values for the periods presented.

Anson Convertible Promissory Notes (the“Anson Notes”)

On* August 12, 2024,*the Company entered into the Anson Purchase Agreement with the Investors, Anson Investment Master Fund LP and Anson East Master Fund LP (collectively “Anson”). 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 Anson Notes divided by the VWAP of the Common Stock, as listed on the Nasdaq Capital Market, on the day prior to the closing of each respective tranche under the Anson Warrants (as defined below).

In connection with the above offering, the Company engaged EF Hutton LLC as placement agent. Pursuant to the terms of the engagement with the placement agent, the Company paid a cash fee of 7% of the gross proceeds the Company receives in the offering at closing.

On* August 14, 2024,the Company entered into thefirst* tranche Senior Secured Convertible Note Agreements (the “First Tranche Notes”) with Anson at various amounts for an aggregate of $5.4 million subject to an original issuance discount of 8% or $435,000, 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 Note12*). $2.5 million of the proceeds from the First Tranche Notes were used to make an initial payment to partially satisfy the Streeterville Note in2024.

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 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.

21

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 Anson 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 stockholder 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.

Pursuant to the Anson Purchase Agreement, on* October 10, 2024 (the “Second Closing Date”), the Company sold a total of $5.4 million in Notes (the “Second Tranche Notes”), subject to an original issue discount of 8% or $435,000 less other cash issuance cost of $375,000, with an aggregate purchase price of approximately $5.0 million, and warrants to purchase up to 1,846,128 shares of Common Stock. The Second Tranche Notes are convertible into Common Stock, at a per share conversion price equal to by the lower of (a) $1.7664 or (b) a price equal to 92% of the lowest VWAP during theseven*-trading day period immediately preceding the effective date set forth in a Notice of Conversion delivered by an Investor to the Company. The Conversion Price is subject to, among other customary provisions, downward adjustment in the event of any future issuance by the Company of Common Stock below the then effective Conversion Price. $3.1 million of the proceeds from the Second Tranche Notes were used to satisfy the remaining amount due in connection with the Streeterville Note.

In connection with the above Second Tranche Notes, the Company engaged a placement agent. Pursuant to the terms of the engagement with the Placement Agent, the Company paid a cash fee of 7% of the gross proceeds the Company received in the Third Closing and incurred certain additional other issuance costs and reimbursement for legal counsel disbursements and placement agent, for aggregate issuance costs of approximately $0.4 million.

Pursuant to the Anson Purchase Agreement, on* January 28, 2025 (*the “Third Closing Date”), the Company sold a total of $5.4 million in Notes subject to an original issue discount of 8% or $0.435 million less other issuance costs of $0.4 million noted below (the “Third Tranche Notes” and collectively with the First Tranche Notes and Second Tranche Notes, the (“Anson Notes”)), with an aggregate purchase price of approximately $5.0 million, and Warrants to purchase up to 862,699 shares of Common Stock. The Third Tranche Notes are convertible into Common Stock, at a per share conversion price equal to by the lower of (a) $3.78 or (b) a price equal to 92% of the lowest VWAP during theseven-trading day period immediately preceding the effective date set forth in a Notice of Conversion delivered by an Investor to the Company. The Conversion Price is subject to, among other customary provisions, downward adjustment in the event of any future issuance by the Company of Common Stock below the then effective Conversion Price.

In connection with the above Third Tranche Notes, the Company paid a cash tail fee to the Placement Agent equal to 7% of the gross proceeds the Company received in the Third Closing and incurred certain additional other issuance costs and reimbursement for legal counsel disbursements, for aggregate issuance costs of approximately $0.4 million.

22

On or about* January 27, 2025,the Company and the Investors entered into a Consent and Waiver Agreement (the “CWA”), relating to certain rights and prohibitions arising under the Anson Purchase Agreement and the Notes. In the CWA, each of the Investors provided its consent under certain restrictive provisions, and waived certain rights, including, among other things, a right to participate in certain Qualified Financings (as defined in the CWA) made by us under the Anson Purchase Agreement and the Notes, the prohibition on issuance of certain equity securities, and waiver of any potential liquidated damages arising under that certain Registration Rights Agreement by and between the Company and the Investors dated August 14, 2024,until March 31, 2025.On March 20, 2025,following the conversion of less than $0.1 million of the Third Tranche Note into 5,463 shares of Common Stock, the Company issued 303,819 shares of Common Stock as Consideration Shares and 303,819 of Consideration Warrants to Anson in accordance with the terms of the CWA (see Note12*).

Due to these embedded features within the Anson Notes, the Company elected to account for the First, Second, and Third 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 condensed consolidated statements of operations. To determine the initial carrying value of the Notes and the warrants issued to Anson under the First, Second, and Third Tranche Notes (see Note12), the Company allocated the proceeds using the 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, the initial carrying value of the Second Tranche Notes and the warrants issued to Anson were $3.1 million and $1.9 million, and the initial carrying value of the Third Tranche Notes and the warrants issued to Anson were $2.5 million and $2.5 million, respectively. Refer to Note14 for the reconciliation of the fair values for the periods presented.

In connection with the Second RD Purchase Agreement, and pursuant to the full ratchet anti-dilution provisions contained in the Anson financing agreements, the Fixed Conversion Price component of the variable conversion formula of the outstanding Anson Notes, and the exercise price of all outstanding Common Stock purchase warrants issued on* August 14, 2024,** October 10, 2024,** January 28, 2025,and January 29, 2025 (collectively, the “Anson Warrants”) were each adjusted to $1.65 per share. In addition, under the full ratchet provision of the warrants’ anti-dilution provision, the number of shares underlying the Anson Warrants was increased by an aggregate of 1,870,960 shares of Company’s Common Stock (see below under “Warrants”). During the quarter ended September 30, 2025,the reduction of the Fixed Conversion Price component of the variable conversion formula of the outstanding Anson Notes pursuant to the anti-dilution provisions is reflected in the change in fair value of convertible notes payable recorded in the consolidated statement of operations for thethree* andnine months ended* September 30, 2025.*

The holders of Anson Notes and Anson Warrants, in accordance with an agreement entered into with Anson on* September 30, 2025,agreed to, among other things, i) certain trading volume limitations, and ii) a partial exercise on previously issued Anson Warrants for cash. Specifically, if the closing stock price of the Company’s common stock as reported on the Principal Market (as defined in the August 2024Purchase Agreement) is below $3.25 on any trading day, Anson may**not* sell, dispose of, or otherwise transfer, in the aggregate, more than 12.5% of the composite daily trading volume of the Company’s common stock on that trading day. In accordance with the agreement, the holders exercised their Anson Warrants for cash, generating net proceeds of $3.09 million and resulting in the issuance of 1,870,960 shares of Company’s Common Stock on* September 30, 2025 (*see “Warrants” below).

During thethree months ended* March 31, 2025,Anson converted $1.3 million and less than $0.1 million of principal and interest of the First and Third Tranche Notes, respectively, into Common Stock, resulting in the aggregate issuances of 1,009,518 shares of Common Stock and loss on conversion of $1.6 million. During thethree* months ended* June 30, 2025,Anson converted $4.1 million of principal and interest of the Third Tranche Note into Common Stock, resulting in the issuance of 1,879,406 shares of Common Stock and loss on conversion of $1.9 million. During thethree* months ended* September 30, 2025,*Anson converted $1.4 million of principal and interest of the Third Tranche Note into Common Stock, resulting in the issuance of 877,193 shares of Common Stock and loss on conversion of $0.8 million.

During the year ended* December 31, 2024,Anson converted $4.2 million of principal and interest of the First Tranche Note into Common Stock, resulting in the issuances of 3,676,796 shares of Common Stock and loss on conversion of $1.3 million. (see Note11*). As of* September 30, 2025,the nominal principal and accrued interest balance of the Anson Notes was $5.4 million and $0.3 million, respectively. During thethree* andnine months ended* September 30, 2025,the Company recorded a loss from the change in fair value of the Second and Third Tranche Notes of $0.8 million and $2.7 million, which was recognized in other expense (income) on the condensed consolidated statements of operations as a result of the Company’s election of the fair value option. At September 30, 2025,the effective interest rates of the Second Tranche Note were 172%. See Note14,* “Fair Value Measurements,” for a summary of activity for the Anson Notes.

This compensation includes additional shares of Common Stock (the “Consideration Shares”) and warrants to purchase an equal number of shares (the “Consideration Warrants”). The exercise price of the warrants is based on a VWAP-Based Adjustment, calculated as the greater of (a) the VWAP on the trading day before the conversion notice, or (b)80% of the closing price on the day before the Registered Direct Offering. As of* September 30, 2025,the obligation under this provision has been fully satisfied.

As a result of this adjustment, the exercise price of the RD Warrants was updated to $2.30 as of March 20, 2025.Upon conversion or extinguishment, ASC470*-50-40-2 requires that any difference between the carrying amount of the debt and the fair value of consideration transferred be recognized as a gain or loss in the statement of operations. The Consideration Shares, being equity-classified, are recognized at fair value with credit to Common Stock and additional paid in capital. The Consideration Warrants, liability-classified under ASC815-40, were initially recognized at fair value, with changes in fair value subsequently recognized through earnings. In accordance with the CWA, the Company recorded loss on issuance of the Consideration shares and the Consideration Warrants in total of $1.28 million recognized within other expense (income) during thenine months ended* September 30, 2025,*within accompanying condensed consolidated statements of operations and comprehensive loss.

On* September 30, 2025,the 1,870,960 shares underlying the Anson Warrants, that were issued with the original convertible notes, were exercised for cash proceeds of $3.09 million. The fair value of the exercised warrants, which were initially recorded as warrant liability, was determined to be $5.37 million as of the exercise date, resulting in a gain of $5.37 million upon settlement of these warrant liabilities exercises, representing the difference between the fair value of the exercised Anson warrants and the cash proceeds received. Because the exercise proceeds were received subsequent to September 30, 2025,the Company recorded a subscription receivable asset of $3.09 million as of September 30, 2025.The gain on Anson warrants exercised was recognized within other expense (income) for thethree* andnine months ended* September 30, 2025.*

In the transaction, Big Rock Merger Corp. merged with and into NeuroRx, with NeuroRx continuing as the surviving entity. In connection with the Merger in2021,* each warrant to purchase shares of Common Stock of NRx that was outstanding and unexercised immediately prior to the effective time (whether vested or unvested) was assumed by Big Rock Partners Acquisition Corp. (“BRPA”) and converted into a warrant, based on the exchange ratio (of 0.316), that will continue to be governed by substantially the same terms and conditions, including vesting, as were applicable to the former warrant (the “Substitute Warrants”). There were 3,792,970 warrants outstanding and unexercised at the effective time. 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 condensed 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. Refer to Note14 for further discussion of fair value measurement of the warrant liabilities.

The Company classifies the Private Placement Warrants as derivative liabilities in its condensed consolidated balance sheets as of* September 30, 2025and December 31, 2024.*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.

Anson Warrants–* Liability*

The Anson Warrants, originally issued in the Anson Purchase Agreement, are recognized as derivative liabilities in accordance with ASC815.

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 are measured at fair value using a Black-Scholes model. Warrant liabilities are classified as current liabilities on the Company's condensed consolidated balance sheets.

On* January 28, 2025,in conjunction with the issuance of the Third Tranche Notes, the Company issued warrants to purchase up to 862,699 shares of Common Stock which were classified as a liability (See Note14*). The warrants had an initial exercise price of $3.78 per share, subject to adjustment or other settlement provisions, and have a contractual term offive years expiring on* January 28, 2030.The measurement of fair value of the Investor Warrants was determined using a Black-Scholes model considering all relevant assumptions current at the date of issuance (i.e., share price of $3.55, exercise price of $3.78, term offive years, volatility of 113%, risk-free rate of 4.33%, and expected dividend rate of 0%). The grant date fair value of these Third Tranche Investor Warrants was estimated to be $2.5 million on January 28, 2025.*

In connection with the Second RD Purchase Agreement, and pursuant to the full ratchet anti-dilution provisions contained in the Anson financing agreements, the exercise price of all outstanding Common Stock purchase warrants issued on* August 14, 2024,** October 10, 2024,** January 28, 2025,and January 29, 2025 (collectively, the “Anson Warrants”) were each adjusted to $1.65 per share. In addition, under the full ratchet provision of the warrants’ anti-dilution provision, the number of shares underlying the Anson Warrants was increased by an aggregate of 1,870,960 shares of common stock. The effect of the full ratchet trigger was$5.7* million and is reflected as part of the change in fair value of warrant liabilities on the statement of operations.

The holders of Anson Notes and Anson Warrants, in accordance with the an agreement entered into with Anson on* September 30, 2025,agreed to, among other things, i) certain trading volume limitations, and ii) a partial exercise of previously issued Anson Warrants for cash. Specifically, if the closing stock price of the Company’s common stock as reported on the Principal Market (as defined in the August 2024Purchase Agreement) is below$3.25* on any trading day, Anson* may**not* sell, dispose of, or otherwise transfer, in the aggregate, more than12.5% of the composite daily trading volume of the Company’s common stock on that trading day. In accordance with the agreement,

1,870,960 shares of underlying Anson Warrants, which were issued with the original convertible notes, were exercised on* September 30, 2025,for cash proceeds of $3.1 million. The fair value of the exercised Anson Warrants liabilities was determined to be $5.4 million as of the exercise date, resulting in a gain of $5.4 million, recorded as gain in exercise of warrant liabilities and representing the difference between the fair value of the exercised Anson Warrants and the cash proceeds received. Because the exercise proceeds were received subsequent to September 30, 2025,the Company recorded a subscription receivable asset of $3.1 million as of September 30, 2025.The gain was recognized within other (income) expense for thethree* andnine months ended* September 30, 2025.*

RD Warrants – Liabilities

As discussed above, on* January 29, 2025,in conjunction with the issuance of the First RD Shares, the Company issued the First RD Warrants to purchase up to 1,215,278 shares of Common Stock which were classified as a liability. The First RD Warrants have an exercise price of $2.88 per share and have a contractual term offive years expiring on January 29, 2030.The measurement of fair value of the First RD Warrants was determined utilizing a Black-Scholes model considering all relevant assumptions current at the date of issuance (i.e., share price of $2.07, exercise price of $2.88, term offive years, volatility of 115.8%, and risk-free rate of 4.00%). The grant date fair value of these First RD Warrants was estimated to be $3.983 million on January 29, 2025.As the fair value of the liabilities exceeded the net proceeds received of $3.255 million, the Company recognized the excess of the fair value over the net proceeds received of $3.255 million as a loss upon issuance of the First Registered Direct Offering of $0.7 million which is included in other expense (income) in the condensed consolidated statement of operations for thenine* months ended* September 30, 2025.*

Consideration Warrants – Liability

As discussed above, on* March 20, 2025,in conjunction with the issuance of the Consideration Shares, the Company issued Consideration Warrants to purchase up to 303,819 shares of Common Stock which were classified as a liability. The Consideration Warrants have an exercise price of $2.88 per share and have a contractual term offive years expiring on March 20, 2030.*

The measurement of fair value of the Consideration Warrants were determined utilizing a Black-Scholes model considering all relevant assumptions current at the date of issuance (i.e., share price of $2.07, exercise price of $2.88, term offive years, volatility of 115.8%, and risk-free rate of 4.00%). The grant date fair value of these Consideration Warrants was estimated to be $0.6 million on* March 20, 2025.*

As of* September 30, 2025,the aggregate fair value of all liability classified warrants, whichinclude Substitute Warrants, Assumed Private Placement Warrants, Anson Warrants, First RD Warrants and Consideration Warrants, was $15.9 million. The Company recognized a loss on the change in fair value of the liability classified warrants for thethree* months ended* September 30, 2025of approximately $5.0 million, and a loss of approximately $8.5 million on the change in fair value of the liability classified warrants for thenine* months ended* September 30, 2025.In addition, the Company recognized a gain of $5.4 million upon the exercise of Anson Warrants, representing the difference between the fair value of the exercised warrant liabilities and the cash proceeds received. Refer to Note14* for discussion of the fair value measurement of the Company’s warrant liabilities.

Note13. Stock-Based Compensation

2016 Omnibus Incentive Plan

Prior to the Merger, the Company 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 Common Stock at an average exercise price of $51.00 per share.

2021 Omnibus Incentive Plan

As of* September 30, 2025,1,050,809 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, 2025,95,528 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, 2023,thefirst* amendment to the2021 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 the2021* Plan to be equal to100% of the Share Pool. As of* September 30, 2025,an aggregate 1,117,099 shares of Common Stock have been awarded net of forfeitures, and 18,085 shares of Common Stock 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.

On* February 7, 2025,the Company issued 50,000 stock options. These shares have a vesting term ofthree* years, an expiration date often years from the grant date and were valued at approximately $0.1 million as of the grant date.

On* April 9, 2025,*the Company issued 497,000 stock options. These shares have a vesting term ofthree years, an expiration date often years from the grant date and were valued at approximately $0.6 million as of the grant date.

The stock options granted during thenine months were valued utilizing the Black-Scholes options pricing model with the following inputs: $1.78-2.94 of stock price,3.91%-4.31% risk-free rate,127%-126.76% volatility,0% dividend rate, and the expected term of 3 years.

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 less than $0.1 million and $0.1 million for thethree months ended* September 30, 2025and2024,* respectively. Stock-based compensation expense related to stock options was approximately $0.15 million and approximately $0.1 million for thenine months ended* September 30, 2025and2024,* respectively.

At* September 30, 2025,*the total unrecognized compensation related to unvested employee and non-employee stock option awards granted was $0.6 million, which the Company expects to recognize over a weighted-average period of approximately 2.49 years.

Restricted Stock Awards

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

On* July 12, 2022,the board of directors (the “Board”) granted an award of 100,000 restricted shares of the Company as an inducement to the newly appointed chief executive officer, pursuant to a separate Restricted Stock Award Agreement (the “RSA”). The Restricted Stock vested 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 granted 57,500 RSAs to a consultant for services provided. The RSAs vested aftersix months from the grant date. 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.

33

Stock-based compensation expense related to RSAs was $0 and less than $0.1 million for thethree months ended* September 30, 2025and2024,* respectively. Stock-based compensation expense related to RSAs was $0 and less than $0.1 million for thenine months ended* September 30, 2025and2024,* respectively.

In* October 2024,the Company's chief executive officer 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 December 31, 2024.*

Note14. 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, 2025and2024.* 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, and warrants issued with the Convertible Notes 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, 2025and December 31, 2024,*and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value (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):

35

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 condensed 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):

Fair Value on a Nonrecurring Basis

Assets and liabilities that are measured at fair value on a nonrecurring basis relate primarily to tangible property and equipment, goodwill and other intangible assets, which are remeasured when the derived fair value is below carrying value in the consolidated balance sheets. For these assets, the Company doesnot periodically adjust carrying value to fair value except in the event of impairment. If it is determined that impairment has occurred, the carrying value of the asset is reduced to fair value and the difference is included in impairments and other charges, net in the consolidated statements of operations.

36

Assets that are measured at fair value and classified as level3 on a non-recurring basis are as follows (in thousands):

All these assets were measured at the acquisition dates in conjunction with the Dura acquisition.

Consideration Transferred

The preliminary fair value of the consideration transferred was $3.3 million, consisting of cash consideration (subject to customary closing adjustments). The preliminary estimated working capital and other customary closing adjustments resulted in a decrease of approximately $0.1 million to the purchase price, which is included in the total consideration transferred.

The following items were determined to represent post-employment compensation under ASC805 and ASC718 and are excluded from the purchase price consideration:

These amounts will be accounted for as compensation expense in future periods as services are rendered.

In connection with the acquisition of Dura, the Company incurred total acquisition-related costs of approximately $0.1 million during thenine months ended* September 30, 2025.*These costs primarily consist of legal, accounting, consulting fees and a finder fee directly attributable to the transaction. These costs were expensed as incurred and are reflected in general and administrative expenses in the unaudited condensed consolidated statements of operations.

Purchase Price Allocation

The Company has applied the acquisition method of accounting in accordance with ASC805, Business Combinations (“ASC805”) and recognized assets acquired, and liabilities assumed at their fair value as of the date of acquisition, with the excess purchase consideration recorded to goodwill. As the Company finalizes the estimation of the fair value of the purchase price and the fair value of the assets acquired and liabilities assumed, additional adjustments* maybe recorded during the measurement period (a periodnot* to exceed12 months from the acquisition date).

39

The Company recorded all tangible and identifiable intangible assets acquired and liabilities assumed at their preliminary estimated fair values as of the acquisition date. The preliminary allocation is as follows:

Certain adjustments of approximately $0.1 million to the purchase price were recorded, decreasing the purchase price during the measurement period ended* September 30, 2025.*Changes to the provisional amounts recognized at the acquisition date—if based on new information about facts and circumstances that existed as of the acquisition—must be accounted for retrospectively during the measurement period.

Intangible Assets

The Company identified the following finite-lived intangible assets, which will be amortized on a straight-line basis over their estimated useful lives once finalized:

The acquired intangible assets are being amortized over their estimated useful lives as follows (in thousands):

As of* September 30, 2025,*the maturities of the Company’s intangible assets were as follows (in thousands):

40

Goodwill of approximately $0.6 million represents the excess of the purchase consideration over the fair value of net assets acquired and was recognized in connection with the acquisition.None of the goodwill is expected to be deductible for tax purposes. The goodwill is assigned to the Dura subsidiary. The goodwill primarily represents expected synergies, assembled workforce, and future growth potential.No goodwill arose from step acquisitions or non-controlling interests.

Measurement Period

The Acquisition was recorded as a business combination on a preliminary valuation of assets acquired and liabilities assumed at their acquisition date fair values using unobservable inputs that are supported by little orno market activity and are significant to their fair value of the assets and liabilities (“Level3” inputs). We expect to complete our purchase price allocation, as well as our fair value estimate of the purchase price consideration as soon as reasonably possible,not to exceedone year from the acquisition date. Adjustments to the preliminary purchase price and allocation could be material. Goodwill and intangible assets represent the excess of the purchase price consideration over the preliminary valuation of the other net assets acquired.

As of* September 30, 2025,the purchase price allocation remains preliminary, and the purchase price may*be subject to final adjustments. The Company is continuing to assess the fair values of certain identifiable intangible assets and contingent liabilities, including the potential adjustment to exchangeable shares.
