Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis of NRx Pharmaceuticals’ financial condition and plan of operations together with NRx Pharmaceuticals' consolidated financial statements and the related notes appearing elsewhere herein. In addition to historical information, this discussion and analysis contains forward looking statements that involve risks, uncertainties and assumptions. NRx Pharmaceuticals’ actual results may differ materially from those discussed below. Factors that could cause or contribute to such differences include, but are not limited to, those identified below, and those discussed in the section entitled “Risk Factors” included elsewhere herein.

Overview

NRx is a clinical-stage bio-pharmaceutical company which develops and plans to distribute, through its wholly-owned operating subsidiaries, NeuroRx, Inc., (“NeuroRx”) and HOPE Therapeutics, Inc. (“HOPE”), novel therapeutics for the treatment of central nervous system disorders including suicidal depression, chronic pain, and PTSD. NeuroRx is organized as a traditional Research and Development (“R&D”) company, whereas HOPE is organized as a Specialty Pharmaceutical (SpecPharma) company intended to distribute ketamine and other therapeutic options to clinics that serve patients with suicidal depression and PTSD.

The 2023 fiscal year was one of extraordinary growth and transition for NRx. During the year the Company restructured its management to overcome challenges in capital formation, clinical trial enrollment, and corporate growth, in a manner that resulted in demonstrable milestones for 2023 and a company that we believe to be poised for growth in 2024. Those milestones achieved in 2023 and through the date of this filing include:

Table of Contents

The Company has two lead compounds today, NRX-100, a proprietary presentation of ketamine and NRX-101, a patented fixed-dose combination of D-cycloserine and lurasidone. Both products have Fast Track designation from the US FDA for the treatment of suicidal bipolar depression. NRX-101 additionally has Breakthrough Therapy Designation and a Biomarker Letter of Support from the FDA for this purpose. To the Company’s knowledge, NRX-101 is the only oral antidepressant demonstrated to reduce suicidal ideation in a phase 2 trial.

For mechanistic reasons unrelated to its CNS NMDA-antagonist properties, NRX-101 interferes with cell wall formation in certain bacteria, rendering it a potent antibiotic and is demonstrated to kill certain treatment-resistant urinary tract bacteria. Accordingly, NRX-101 has been awarded Qualified Infectious Disease Product Designation and Fast Track Designation by the FDA to treat Complicated Urinary Tract Infection and Pyelonephritis. Our strategy is to apply innovative science to known molecules in the pursuit of therapies for high unmet needs, including lethal conditions (NeuroRx) and to distribute ketamine and ancillary therapies to qualified clinics and practitioners who treat patients with suicidal depression (HOPE). The Company has announced plans to spin off HOPE to a freestanding company, half of which will be owned by NRx and half by individual shareholders.

NRX-101 has been awarded Fast Track designation, Breakthrough Therapy designation, a Biomarker Letter of Support, and a Special Protocol Agreement by the FDA. Peer-reviewed and published results from Phase II clinical studies demonstrate a significant decline and stabilization in symptoms of depression and suicidality following administration of DCS in combination with antidepressants. Findings from one of these studies found that bipolar patients who were already receiving a 5-HT2a antagonist demonstrated more than a 50% reduction in symptoms of depression and a 75% reduction in suicidal ideation when ketamine and DCS were added to their treatment regimen. Side effects for patients in a Phase 2a combination study of DCS and 5HT2a included mild sedation, headaches and hypomania. Breakthrough Therapy designation was awarded based on data from the STABIL-B study (NCT02974010) that demonstrated a statistically significant advantage of NRX-101 vs. lurasidone (the active ingredient used in the market leading branded bipolar depression agent) in maintaining remission from depression and suicidality following a single stabilizing dose of ketamine.

Recent Events

February 2024 Offerings

On February 27, 2024, we entered into the Underwriting Agreement with EF Hutton LLC, as the Representative of the Underwriters, relating to the February 2024 Public Offering of 5,000,000 shares of the Common Stock. The public offering price for each share of Common Stock was $0.30, and the Underwriters purchased the shares of Common Stock pursuant to the Underwriting Agreement at a price for each share of Common Stock of $0.276. On February 28, 2024, the February 2024 Public Offering closed (the “Closing Date”). Aggregate gross proceeds from the February 2024 Public Offering were approximately $1.5 million, before deducting underwriting discounts and commissions and estimated expenses payable by the Company.

Table of Contents

Pursuant to the Underwriting Agreement and the engagement letter, dated as of February 22, 2024, by and between the Company and the Representative, the Company agreed to issue to the Representative in connection with the February 2024 Public Offering, a warrant to purchase up to a number of shares of Common Stock representing 5.0% of the shares of Common Stock and any Option Shares (as defined below) sold, at an initial exercise price of $0.33 per share, subject to certain adjustments (the “Underwriter’s Warrant”). On February 28, 2024, the Company issued to the Representative the Underwriter’s Warrant to purchase up to 250,000 shares of Common Stock (the “Underwriter Warrant Shares”). The Underwriter’s Warrant is exercisable six months following the date of the Underwriting Agreement and terminates on the five-year anniversary of the date of the Underwriting Agreement.

Pursuant to the Underwriting Agreement, the Company also granted the Representative a 45-day Over-Allotment Option to purchase up to an additional 750,000 Option Shares. On March 5, 2024, the Underwriters exercised the Over-Allotment Option to purchase an additional 750,000 Option Shares. In connection with the Overallotment Exercise, we issued an additional Underwriter’s Warrant to purchase up to 37,500 shares of Common Stock. The Overallotment Exercise closed on March 6, 2024.

On February 29, 2024, we entered into a securities purchase agreement with an investor providing for the issuance and sale of 2,700,000 shares of Common Stock and warrants to purchase up to 2,700,000 shares of Common Stock (the “February Warrants”) at a price of $0.38 per share of Common Stock and accompanying warrant, which represents a 26.7% premium to the offering price in February 2024 Public Offering. The Common Stock and the February Warrants were offered pursuant to a private placement (the “February 2024 Private Placement”) under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). The February Warrants will have an exercise price of $0.38 per share, are initially exercisable beginning six months following the date of issuance, and will expire 5 years from the date of issuance. The aggregate net cash proceeds to the Company from the February 2024 Private Placement were approximately $1.0 million.

Financial Results

Since inception, NRx Pharmaceuticals has incurred significant operating losses. For the years ended December 31, 2023 and 2022, NRx Pharmaceuticals’ net loss was $30.2 million and $39.8 million, respectively. As of December 31, 2023, NRx Pharmaceuticals had an accumulated deficit of $253.1 million, a stockholders’ deficit of $11.7 million and a working capital deficit of $12.2 million.

Going Concern

The Company’s ongoing clinical activities continue to generate losses and net cash outflows from operations. The Company plans to pursue additional equity or debt financing or refinancing opportunities in 2024 to fund ongoing clinical activities, to meet obligations under its current debt arrangements and for the general corporate purposes of the Company. Such arrangements may take the form of loans, equity offerings, strategic agreements, licensing agreements, joint ventures or other agreements. The sale of equity could result in additional dilution to the Company’s existing shareholders. The Company cannot make any assurances that additional financing will be available to it and, if available, on acceptable terms, or that it will be able to refinance its existing debt obligations which could negatively impact the Company’s business and operations and could also lead to a reduction in the Company’s operations. We will continue to carefully monitor the impact of our continuing operations on our working capital needs and debt repayment obligations. As such, the Company has concluded that substantial doubt exists about the Company’s ability to continue as a going concern for a period of at least twelve months from the date of issuance of these consolidated financial statements. The Company may raise substantial additional funds, and if it does so, it may do so through one or more of the following: issuance of additional debt or equity and/or the completion of a licensing or other commercial transaction for one of the Company’s product candidates.

The accompanying 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 consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that may be necessary if the Company is unable to continue as a going concern.

Nasdaq Listing Requirements

On July 20, 2023, we received a written notification (the “Notice”) from the Nasdaq Stock Market LLC (“Nasdaq”) indicating that NRx Pharmaceuticals is not in compliance with Nasdaq Listing Rule 5450(b)(2)(A) – Market Value of Listed Securities (“MVLS”) because the Company had not maintained a minimum MVLS of $50,000,000 for the last thirty-three (33) consecutive business days. Pursuant to Nasdaq Listing Rule 5810(c)(3)(C), we have been provided an initial compliance period of 180 calendar days, or until January 22, 2024, to regain compliance with the MVLS requirement. To regain compliance, our MVLS must meet or exceed $50,000,000 for a minimum period of ten consecutive business days prior to January 22, 2024. If we do not regain compliance within the allotted compliance period Nasdaq will provide notice that our shares of common stock will be subject to delisting and may potentially be traded on the Over-the-Counter market thereafter.

On October 17, 2023, we received formal notice from the Nasdaq Listing Qualifications Staff (the “Staff”) indicating that, based upon our non-compliance with the minimum bid price requirement for continued listing on The Nasdaq Global Market, as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Rule”), our securities were subject to delisting unless we timely request a hearing before the Nasdaq Hearings Panel (the “Panel”), which such hearing was timely requested and subsequently held on January 4, 2024. On January 16, 2024, the Panel granted our request for an exception to the Nasdaq Listing Rules until April 16, 2024, to demonstrate compliance with the Minimum Bid Price Requirement, subject to our filing all necessary documentation required to transfer our listing from the Nasdaq Global Market to the Nasdaq Capital Market on or before January 19, 2024, and our demonstrating compliance with the Minimum Bid Price Requirement on or before April 16, 2024. On February 1, 2024, the Nasdaq Stock Market informed us that it had approved our application to transfer our listing to the Nasdaq Capital Market. Our securities were transferred from the Nasdaq Global Market to the Nasdaq Capital Market at the opening of business on January 19, 2024. We have received authorization from our stockholders for a reverse stock split which is anticipated to occur prior to the April 16th deadline if necessary.

The Company has been granted an exception by the Nasdaq Hearing Panel to meet compliance requirements by April 16, 2024. This is conditional upon the Company completing a transfer of its listing from The Nasdaq Global Market to the Nasdaq Capital Market, which was approved and took effect at the opening of business on January 19, 2024. The Company subsequently established compliance with the Nasdaq Market Value of Listed Securities requirement and was notified of this by the Nasdaq.

Interest income

For the year ended December 31, 2023, NRx Pharmaceuticals recorded $0.5 million of interest income compared $0.2 of interest income for the year ended December 31, 2022. The increase of $0.3 million is due to interest earned in the Company’s money market account.

Table of Contents

Interest expense

For the year ended December 31, 2023, NRx Pharmaceuticals recorded $0.1 million of interest expense, compared to no interest expense for the year ended December 31, 2022. The increase of $0.1 million is due to premiums for cash payments on the convertible note.

Change in fair value of convertible note payable

For the year ended December 31, 2023, NRx Pharmaceuticals recorded a loss of approximately $2.7 million related to the change in fair value of the convertible note payable which is accounted for under the fair value option. For the year ended December 31, 2022, NRx Pharmaceuticals recorded $0.5 million related to the change in fair value of the convertible note payable which is accounted for under the fair value option.

Change in fair value of warrant liabilities

For the year ended December 31, 2023, NRx Pharmaceuticals recorded a gain of less than $0.1 million related to the change in fair value of the warrant liabilities compared to a gain of $0.3 million for the year ended December 31, 2022. The decrease of $0.2 million related to the decrease in the fair value of certain Substitute Warrants and the Placement Warrants assumed pursuant to the Merger Agreement.

Change in fair value of earnout cash liability

For the year ended December 31, 2023, NRx Pharmaceuticals recorded no change in fair value of the earnout cash liability compared to a gain of $4.6 million for the year ended December 31, 2022. The earnout cash milestones were not achieved by December 31, 2022 and therefore the earnout cash liability expired. The gain for the year ended December 31, 2022 related to the expiration of the Company’s obligation.

Liquidity and Capital Resources

The Company has generated no revenues, has incurred operating losses since inception, expects to continue to incur significant operating losses for the foreseeable future and may never become profitable. Until such time as the Company is able to establish a revenue stream from the sale of its therapeutic products, NRx Pharmaceuticals is dependent upon obtaining necessary equity and/or debt financing to continue operations. NRx Pharmaceuticals cannot make any assurances that sales of NRX-101 will commence in the near term or that additional financings will be available to it on acceptable terms or at all. This could negatively impact NRx Pharmaceuticals' business and operations and could also lead to the reduction of NRx Pharmaceuticals' operations.

February 2024 Offerings

On February 27, 2024, the Company entered into an Underwriting Agreement with EF Hutton LLC, as the Representative of the Underwriters, relating to the February 2024 Public Offering. The public offering price for each share of Common Stock was $0.30 and the Underwriters purchased the shares of Common Stock pursuant to the Underwriting Agreement at a price for each share of Common Stock of $0.276. Pursuant to the Underwriting Agreement, the Company also granted the Representative the Over-Allotment Option. Aggregate gross proceeds from the Offering were approximately $1.5 million, before deducting underwriting discounts and commissions and estimated expenses payable by the Company. The Company intends to use the net proceeds from the February 2024 Public Offering for working capital and general corporate purposes. The Company may also use the proceeds from February 2024 Public Offering to repay the Convertible Promissory Note initially issued to Streeterville Capital, LLC in November 2022.

On March 5, 2024, the Underwriters in the February 2024 Public Offering exercised their Over-Allotment Option to

purchase an additional 750,000 Option Shares. In connection with the Overallotment Exercise, we issued an additional

Underwriter’s Warrant to purchase up to 37,500 shares of Common Stock. The Overallotment Exercise closed on March

6, 2024.

On February 29, 2024, we entered into a securities purchase agreement with an investor providing for the issuance and sale of 2,700,000 shares of Common Stock and warrants to purchase up to 2,700,000 shares of Common Stock (the “February Warrants”) at a price of $0.38 per share of Common Stock and accompanying warrant, which represents a 26.7% premium to the offering price in February 2024 Public Offering. The Common Stock and the February Warrants were offered pursuant to a private placement (the “February 2024 Private Placement”) under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). The February Warrants will have an exercise price of $0.38 per share, are initially exercisable beginning six months following the date of issuance, and will expire 5 years from the date of issuance. The aggregate net cash proceeds to the Company from the February 2024 Private Placement were approximately $1.0 million.

Private Placement

On February 2, 2022, the Company completed a private placement and issued 7,824,727 shares of common stock and Preferred Investment Options to purchase up to an aggregate of 7,824,727 shares of common stock. The Preferred Investment Options have an exercise price of $3.07 per share and may be exercised any time on or after August 2, 2022.

The form of the Preferred Investment Option is a warrant. The measurement of fair value was determined utilizing a Black-Scholes model considering all relevant assumptions current at February 2, 2022, the date of issuance (i.e., share price of $2.94, exercise price of $3.07, term of five years beginning August 2, 2022, volatility of 82.8%, risk-free rate of 1.60%, and expected dividend rate of 0%). The grant date fair value of these Preferred Investment Options was estimated to be $15.5 million on February 2, 2022 and is reflected within additional paid-in capital as of December 31, 2022.

In addition, on February 2, 2022, the Company issued fully vested Preferred Investment Options to the placement agent with an exercise price of $3.99. As these Preferred Investment Options were issued for services provided in facilitating the private placement, the Company recorded the fair value of such Preferred Investment Options as a cost of capital on the issuance date. The measurement of fair value was determined utilizing a Black-Scholes model considering all relevant assumptions current at February 2, 2022, the date of issuance (i.e., share price of $2.94, exercise price of $3.99, term of five years beginning August 2, 2022, volatility of 82.8%, risk-free rate of 1.60%, and expected dividend rate of 0%).

Streeterville Note

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

The Company has the option to prepay the Note during the term by paying an amount equal to 110% of the principal, interest, and fees owed as of the prepayment date. The noteholder has the right to redeem up to $1.0 million of the outstanding balance of the Note per month starting six months after the issuance date. Payments may be made by the Company at their option in: (i) in cash with a 10% premium for the amount redeemed, (ii) by paying the redemption amount in the form of shares of Common Stock with the number of redemption shares being equal to the portion of the applicable redemption amount divided by the Redemption Conversion Price (as defined below), or (iii) a combination of cash and shares of common stock. The “Redemption Conversion Price” on any given redemption date equals 85% multiplied by the average of the two lowest daily volume weighted average prices per share of the common stock during the ten trading days immediately preceding the date that the noteholder delivers notice electing to redeem a portion of the Note. Beginning May 1, 2023, in the event (a) the daily dollar trading volume of the common stock of the Company on any given trading day is at least fifty percent (50%) greater than the lower of (i) the median daily dollar trading volume over the previous ten (10) trading days or (ii) the daily dollar trading volume on the trading day immediately preceding the date of measurement or (b) if the closing trade price on any given trading day is at least thirty percent (30%) greater than the Nasdaq Minimum Price, then the lender will be entitled to redeem over the following ten (10) trading days an amount of indebtedness then outstanding under the Note equal to twice the monthly redemption amount of $1.0 million solely by payment by stock, if permitted under the agreement, subject to the Maximum Percentage (as defined in the Note) and other ownership limitations. On March 30, 2023, the Company entered into an Amendment to the Note (the “First Amendment”), pursuant to which the Maximum Percentage was set at 9.99% of the number of shares of Common Stock outstanding on a given date.

Table of Contents

On July 7, 2023, the Company entered into Amendment #2 to the Note with Streeterville (the “Second Amendment”). Pursuant to the Second Amendment, the Company agreed to amend the redemption provisions of the Note to provide that the Company would pay to Streeterville an amount in cash equal to $1,800,000 on or before July 10, 2023, which amount was paid on July 10, 2023. In addition, the Company agreed that, beginning on or before July 31, 2023, and on or before the last day of each month until December 31, 2023 (the “Minimum Payment Period”), we would pay Streeterville an amount equal to $400,000 in cash (a “Minimum Payment”), less any amount satisfied by the delivery of Redemption Conversion Shares (as defined below). Notwithstanding the foregoing, Streeterville may also submit a request for redemption of up to an aggregate of $1,000,000 per month (the “Maximum Monthly Redemption Amount” and, together with the Minimum Payment Amount, the “Redemption Amounts”) in accordance with the terms of the Note. However, the portion of each Minimum Payment that is not satisfied by the delivery of Redemption Conversion Shares is the maximum amount of cash we will be required to pay in accordance with the Second Amendment during the Minimum Payment Period. The redemption of the Maximum Monthly Redemption Amount in excess of the Minimum Amount may be satisfied by the delivery of additional Redemption Conversion Shares.

On February 9, 2024, the Company entered into Amendment #3 to Convertible Promissory Note (the “Third Amendment”), with Streeterville Capital, LLC (“Streeterville”). Pursuant to the Third Amendment, the Company and Streeterville agreed to further amend the terms of that certain Convertible Promissory Note dated November 4, 2022, in the original principal amount of $11,020,000, as amended by the amendments to the Convertible Promissory Note dated March 30, 2023 and July 7, 2023 (as amended, the “Note”).

In particular, the Company agreed to pay Streeterville an amount in cash equal to $1,100,000 on February 12, 2024.

Notwithstanding the foregoing, after April 30, 2024, and for the remainder of the Minimum Payment Period, Streeterville may redeem any Redemption Amount (as defined in the Note), including an amount in excess of the Minimum Payment, subject to the Maximum Monthly Redemption Amount (as defined in the Note). During the Minimum Payment Period, the Company is permitted to pay the Redemption Amounts in the form of shares of common stock of the Company (the “Redemption Conversion Shares”) calculated on the basis of the Redemption Conversion Price (as defined in the Note) without regard to the existence of any Equity Conditions Failure to the extent Streeterville submits redemption notices during such month pursuant to the terms of the Note, and only for the Redemption Amounts covered by such notices. Moreover, the Redemption Premium (as defined in the Note) will continue to apply to the Redemption Amounts. To the extent there is an outstanding balance under the Note after the expiration of the Minimum Payment Period, the Company will be required to pay such outstanding balance in full in cash by August 31, 2024.

During the Minimum Payment Period, the Company is permitted to pay the Redemption Amounts in the form of shares of common stock of the Company (the “Redemption Conversion Shares”) calculated on the basis of the Redemption Conversion Price (as defined in the Note) without regard to the existence of an Equity Conditions Failure.

Alvogen License Agreement

97

Table of Contents

On June 2, 2023, the Company entered into a License Agreement (the “License Agreement”) with Alvogen Pharma US, Inc., Alvogen, Inc. and Lotus Pharmaceutical Co. Ltd. (collectively, “Alvogen”). Under the License Agreement, NRx granted Alvogen an exclusive, worldwide, transferable and sublicensable license under certain intellectual property (including patents, know-how and trademarks) owned or controlled by NRx to develop (with certain limitations), manufacture, and commercialize NRX-101, for the treatment of bipolar depression with suicidality. The term of the license is, on a country-by-country basis, 20 years from the first commercial sale of NRX-101 in such country, extendable by Alvogen for a two-year period upon its request made prior to the expiration of such 20-year period. During the term of the License Agreement, the parties have agreed (on behalf of themselves and their affiliates) not to research, develop, seek or obtain any regulatory approval for the manufacturing, marketing, sale, or other commercialization of any product containing a fixed dose combination of D-cycloserine and lurasidone in the treatment of bipolar depression with suicidality, nor to authorize or assist (including by investing in or otherwise providing funding to) any third party to do so.

During the term of the License Agreement, NRx is permitted to develop additional products containing D-cycloserine in combination with one or more other active antidepressant or antipsychotic ingredients for use outside of the field of treatment of bipolar depression with suicidality, such as in post-traumatic stress disorder (PTSD) or chronic pain in depression, in which case, if NRx wishes to license rights to develop or commercialize such additional products or indications, Alvogen has a right of first negotiation to obtain such a license.

Under the terms of the License Agreement, we have the right to an aggregate of up to $330 million in cash milestone payments, including an initial $10 million First Milestone Payment, upon the achievement of certain milestones. A second milestone payment of $5 million is due upon Alvogen’s receipt of a copy of the FDA’s notice of NDA Approval for Product with the label indication for the treatment of bipolar depression with sub-acute or acute suicidality. Additional cash milestone payments will become payable to us upon the achievement of net sales targets measured over the trailing four quarters. Alvogen has also agreed to pay the Company royalties based on the net sales of NRX-101.

Alvogen advance of milestone

As of February 7, 2024, the Alvogen agreement was amended and the company became eligible to receive $5 million as an advance of the first Milestone completion within the Alvogen Agreement.

June Offering

On June 6, 2023, the Company entered into a securities purchase agreement with institutional investors (the “June Investors”), providing for the issuance and sale of 9,670,002 shares of the Company’s Common Stock and warrants to purchase up to 9,670,002 shares of Common Stock (the “June Investor Warrants”). The Common Stock was issued in a registered direct offering for a purchase price of $0.65 per share (the “June Offering”) and the June Investor Warrants were offered pursuant to a private placement under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). The June Investor Warrants have an exercise price of $0.6525 per share, are initially exercisable beginning six months following the date of issuance (the “June Initial Exercise Date”) and will expire five and one half years from the date of issuance. The aggregate net cash proceeds to the Company from the June Offering were approximately $5.6 million.

At The Market Offering

On August 14, 2023, we entered into an At The Market Offering Agreement (the “Sales Agreement”) with H.C. Wainwright & Co., LLC (“Wainwright”), as sales agent, pursuant to which we may offer and sell, from time to time through Wainwright, shares of Common Stock having an aggregate offering price of up to $2,000,000 (the “ATM Shares”). Upon delivery of an issuance notice and subject to the terms and conditions of the Sales Agreement, Wainwright may sell the ATM Shares by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act. We are not obligated to make any sales of the ATM Shares under the Sales Agreement. The offering pursuant to the Sales Agreement will terminate upon the earlier of (i) the issuance and sale of all the sale of the ATM Shares reaching an aggregate offering amount equal to $2,000,000, or (ii) the termination of the Sales Agreement as permitted therein. The Company will pay Wainwright a commission rate of up to 3.0% of the aggregate gross proceeds from each sale of ATM Shares and has agreed to provide Wainwright with customary indemnification and contribution rights. The Company will

also reimburse Wainwright for certain specified expenses in connection with entering into the Sales Agreement. For the year ended December 31, 2023, we did not sell any shares of Common Stock pursuant to the Sales Agreement.

August Offering

On August 28, 2023, the Company entered into a securities purchase agreement (the “Preferred Stock Securities Purchase Agreement”) with certain purchasers (the “August Investors”), pursuant to which the Company issued 3,000,000 shares of the Company’s Series A Convertible Preferred Stock, par value $0.001 per share (the “Series A Preferred Stock”), and one (1) investor warrant (each an “August Investor Warrant”) for every share of Series A Preferred Stock issued. The shares of Series A Preferred Stock and the August Investor Warrants were offered pursuant to a private placement under Section 4(a)(2) of the Securities Act. Each August Investor Warrant entitles the holder to purchase one (1) share of Common Stock at a purchase price of $0.40 per share. The aggregate purchase price for each share of Series A Preferred Stock and associated August Investor Warrant was $0.40. The August Investor Warrants are exercisable starting on the six month anniversary of the date of issuance and will have a term of five years from the date of issuance. The August Investor Warrants may also be exercised during the initial six-month period after issuance, at the option of the August Investors, if the closing share price of the Common Stock equals or exceeds $1.20 per share on any trading day.The aggregate gross proceeds to the Company from the private placement was approximately $1.0 million before expenses.

Off-Balance Sheet Arrangements

The Company is not party to any off-balance sheet transactions. The Company has no guarantees or obligations other than those which arise out of normal business operations.

Critical Accounting Policies and Significant Judgments and Estimates

The Company's management’s discussion and analysis of its financial condition and results of operations is based on its financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). The preparation of these financial statements requires NRx Pharmaceuticals to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the balance sheet and the reported amounts of expenses during the reporting period. In accordance with GAAP, NRx Pharmaceuticals evaluates its estimates and judgments on an ongoing basis. The most significant estimates relate to the earnout cash liability, stock-based compensation, and the valuation of warrants. NRx Pharmaceuticals bases its estimates and assumptions on current facts, historical experiences, and various other factors that NRx Pharmaceuticals believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

NRx Pharmaceuticals defines its critical accounting policies as those accounting principles that require it to make subjective estimates and judgments about matters that are uncertain and are likely to have a material impact on its financial condition and results of operations, as well as the specific manner in which NRx Pharmaceuticals applies those principles. While its significant accounting policies are more fully described in Note 3 to its financial statements, NRx Pharmaceuticals believes the following are the critical accounting policies used in the preparation of its financial statements that require significant estimates and judgments.

Stock-based compensation

We measure stock option awards granted to employees and directors based on the fair value of the award on the date of the grant and recognize compensation expense of those awards over the requisite service period, which is generally the vesting period of the respective award. For restricted stock awards, the grant date fair value is the fair market value per share as of

100

Table of Contents

the grant date based on the closing trading price for the Company’s stock. The straight-line method of expense recognition is applied to awards with service-only conditions. We account for forfeitures as they occur.

We estimate the fair value of each stock option award using the Black-Scholes option-pricing model, which uses as inputs the fair value of our common stock and assumptions we make for the volatility of our common stock, the expected term of our stock-based awards, the risk-free interest rate for a period that approximates the expected term of our stock-based awards, and our expected dividend yield. Therefore, we estimate our expected volatility based on the implied volatility of publicly traded warrants on our common stock and historical volatility of a set of our publicly traded peer companies. We estimate the expected term of our options using the "simplified" method for awards that qualify as "plain-vanilla" options. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is based on the fact that we have never paid cash dividends on common stock and do not expect to pay any cash dividends in the foreseeable future.

The assumptions used in determining the fair value of stock-based awards represent reasonable estimates, but the estimates involve inherent uncertainties and the application of our judgment. As a result, if factors change and we use significantly different assumptions or estimates, our stock-based compensation expense could be materially different in the future.

Warrant liabilities

We account 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 ASC 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, 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 do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, or date of modification, 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 fair value of the Private Placement Warrants was estimated using a Black Scholes valuation approach and the fair value of the Substitute Warrants was estimated using a modified Black Scholes valuation approach which applies a probability factor based on the earnout cash milestone and earnout shares milestone probabilities of achievement at each reporting period.

Convertible note payable

As permitted under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 825, Financial Instruments (“ASC 825”), the Company elects to account for its convertible promissory note, which meets the required criteria, at fair value at inception and at each subsequent reporting date. Subsequent changes in fair value are recorded as a component of non-operating loss in the consolidated statements of operations. As a result of electing the fair value option, direct costs and fees related to the convertible promissory notes are expensed as incurred.

The Company estimates the fair value of the convertible note payable using a Monte Carlo simulation model, which uses as inputs the fair value of our common stock and estimates for the equity volatility and volume volatility of our common stock, the time to expiration(i.e. expected termination date) of the convertible note, the risk-free interest rate for a period that approximates the time to expiration, and probability of default. Therefore, we estimate our expected future equity and volume volatility based on the historical volatility of both our common stock 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 mandatory and potential accelerated redemptions beginning six months from the issuance date. The risk-free interest rate is determined

101

Table of Contents

by reference to the U.S. Treasury yield curve in effect at the time of measurement for time periods approximately equal to the time to expiration. Probability of default is estimated using Bloomberg's Default Risk function which uses our financial information to calculate a default risk specific to the Company.

The assumptions used in determining the fair value of the convertible note payable represent reasonable estimates, but the estimates involve inherent uncertainties and the application of our judgment. As a result, if factors change and we use significantly different assumptions or estimates, the change in fair value of the convertible note payable recorded to other (income) expense could be materially different in the future.

NRX Pharmaceuticals, Inc.:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of NRX Pharmaceuticals, Inc. and subsidiary (the “Company”) as of December 31, 2023, the related consolidated statements of operations and comprehensive loss, changes in stockholders’ equity (deficit) and cash flows for the year then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2023, and the consolidated results of its operations and its cash flows for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company has no revenues, has suffered operating losses since inception and in fiscal 2023 has a net loss of $30.2 million and cash used in operations of $21.7 million. The Company also had an accumulated deficit, stockholders’ deficit and working capital deficit as of December 31, 2023 of $253.2 million, $11.7 million and $12.2 million, respectively. These matters raise substantial doubt about the Company’s ability to continue as a going concern. Management’s Plans in regard to these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. Thecommunicationofcriticalauditmattersdoesnotalterinanywayouropinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which theyrelate.

Fair Value of the Convertible Note

As described in Note 3 “Convertible Note Payable” and in Notes 7 and 11 to the consolidated financial statements, the Company uses a Monte Carlo simulation model to estimate the fair value of its convertible note.

We identified the valuation of fair value of the convertible note as of December 31, 2023 as a critical audit matter. Auditing management’s assumptions and estimates relating to the Monte Carlo simulation model is especially challenging, complex and subjective.

The primary procedures we performed to address this critical audit matter included (a) gained an understanding of management’s process to develop an estimate of the fair value of the convertible note, (b) tested the data and assumptions used as inputs to the Monte Carlo simulation model for reasonableness, (c) computed an independent expectation of the fair value of the convertible note and (d) compared management’s valuation to our independent expectation. We agreed with management’s estimate.

Assessment of the fair value of the convertible note

As discussed in Notes 7 and 11 to the consolidated financial statements, the Company completed a convertible note offering during the year ended December 31, 2022. The Company received net proceeds of $10.0 million from the offering and elected to account for this convertible note at fair value under the fair value option. The estimated fair value of the convertible note as of December 31, 2022 is $10.5 million. The Company used a Monte Carlo simulation model to estimate the fair value of the convertible note.

We identified the assessment of the measurement of fair value of the convertible note as of December 31, 2022 as a critical audit matter. This matter required the involvement of valuation professionals with specialized skills and knowledge to assess the Company’s model used to value the convertible note.

The following is the primary procedure we performed to address this critical audit matter. We involved valuation professionals with specialized skills and knowledge who assisted by independently developing a range of fair values of the convertible note using a discounted cash flow model and comparing it to the amount recorded by the Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization

The Business

The Company is a clinical-stage pharmaceutical company which applies innovative science to known molecules to develop life-saving medicines through its wholly-owned operating subsidiary, NeuroRx. The Company's foundation product, NRX-101 (D-cycloserine/Lurasidone), for the treatment of bipolar depression in patients with suicidality, has been awarded Fast Track designation, Breakthrough Therapy designation, a Special Protocol Agreement, and a Biomarker Letter of Support by the U.S. Food and Drug Administration (the “FDA”). NRX-101 is covered by multiple U.S. and foreign patents, including a Composition of Matter patent (U.S. Patent No. 10,583,138) that was transferred to NRx Pharmaceuticals by Glytech, LLC (see Note 13).

Operations

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

2. Going Concern

As of December 31, 2023, the Company had $4.6 million in cash. With the completion of enrollment in its clinical trial of NRX-101 for bipolar depression, the Company anticipates a reduction in its monthly cash expenditure.Since inception, the Company has experienced net losses and negative cash flows from operations each fiscal year and has a working capital deficit at December 31, 2023. The Company has no revenues and expects to continue to incur operating losses for the foreseeable future and may never become profitable. The Company’s ability to support its ongoing capital needs is dependent on its ability to continue to raise equity and/or debt financing, which may not be available on favorable terms, or at all, in order to continue operations.

The Company’s ongoing clinical activities continue to generate losses and net cash outflows from operations. The Company plans to pursue additional equity or debt financing or refinancing opportunities in 2024 to fund ongoing clinical activities, to meet obligations under its current debt arrangements and for the general corporate purposes of the Company. Such arrangements may take the form of loans, equity offerings, strategic agreements, licensing agreements, joint ventures or other agreements. The sale of equity could result in additional dilution to the Company’s existing shareholders. The Company cannot make any assurances that additional financing will be available to it and, if available, on acceptable terms, or that it will be able to refinance its existing debt obligations which could negatively impact the Company’s business and operations and could also lead to a reduction in the Company’s operations. We will continue to carefully monitor the impact of our continuing operations on our working capital needs and debt repayment obligations. As such, the Company has concluded that substantial doubt exists about the Company’s ability to continue as a going concern for a period of at least twelve months from the date of issuance of these consolidated financial statements. The Company may raise substantial additional funds, and if it does so, it may do so through one or more of the following: issuance of additional debt or equity and/or the completion of a licensing or other commercial transaction for one of the Company’s product candidates.

From February 20, 2024, to March 11, 2024, the Company sold 345,829 shares of common stock under the 2020 At The Market (“ATM”) offering at a range of $0.46 - $0.71 per share, for which the Company received net proceeds of $0.2 million, after deducting commissions, fees and expenses.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

On February 27, 2024, NRx Pharmaceuticals, Inc. entered into an underwriting agreement (the “Underwriting Agreement”) with EF Hutton LLC (the “Representative”), as the representative of the several underwriters named therein (the “Underwriters”), relating to an underwritten public offering (the “February 2024 Offering”) of 5,000,000 shares (the “Shares”) of the Company’s common stock, par value $0.001 per share (“Common Stock”). The public offering price for each share of Common Stock was $0.30 and the Underwriters purchased the shares of Common Stock pursuant to the Underwriting Agreement at a price for each share of Common Stock of $0.276. Pursuant to the Underwriting Agreement, the Company also granted the Representative a 45-day option to purchase up to an additional 750,000 shares (the “Option Shares”) of the Common Stock on the same terms as the Shares sold in the Offering. On February 28, 2024, the February 2024 Offering closed with gross proceeds of $1.5 million and net proceeds to the Company of $1.3 million after offering costs. On March 5, 2024, the underwriters of the previously announced underwritten public offering of NRx Pharmaceuticals, Inc. exercised their option in accordance with the Underwriting Agreement, dated February 27, 2024, by and between the Company and EF Hutton LLC, as representative of the several underwriters named therein, to purchase up to an additional 750,000 shares of the Company’s common stock, par value $0.001 per share, at a public offering price of $0.30 per share (the “Overallotment Exercise”). The Overallotment Exercise closed on March 6, 2024. The Overallotment Exercise closed on March 6, 2024. Aggregate net funds received from the transaction were approximately $0.2 million.

On February 29, 2024, we entered into a securities purchase agreement with an investor providing for the issuance and sale of 2,700,000 shares of Common Stock and warrants to purchase up to 2,700,000 shares of Common Stock (the “February Warrants”) at a price of $0.38 per share of Common Stock and accompanying warrant, which represents a 26.7% premium to the offering price in February 2024 Public Offering. The Common Stock and the February Warrants were offered pursuant to a private placement (the “February 2024 Private Placement”) under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). The February Warrants will have an exercise price of $0.38 per share, are initially exercisable beginning six months following the date of issuance, and will expire 5 years from the date of issuance. The aggregate net cash proceeds to the Company from the February 2024 Private Placement were approximately $1.0 million.

The accompanying 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 consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that may be necessary if the Company is unable to continue as a going concern.

3. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The Company’s 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”). The consolidated financial statements include the accounts of NRX Pharmaceuticals, Inc. and its wholly owned subsidiary. All intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates

The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in its consolidated financial statements and the reported amounts of expenses during the reporting period. The most significant estimates in the Company’s consolidated financial statements relate to the fair value of the convertible note payable, earnout cash liability, fair value of stock options and warrants, and the utilization of deferred tax assets. These estimates and assumptions are based on current facts, historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of expenses that are not readily apparent from other sources. Actual results may differ

113

Table of Contents

NRX PHARMACEUTICALS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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, but not limited to, development by the Company or its competitors of new technological innovations, dependence on key personnel, reliance on third party manufacturers, protection of proprietary technology, and compliance with regulatory requirements.

Fair Value of Financial Instruments

ASC 820, Fair Value Measurements, 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 in one of the following three categories for disclosure purposes:

Level 1: Quoted prices in active markets for identical assets or liabilities.

Level 2: Inputs other than Level 1 prices for similar assets or liabilities that are directly or indirectly observable in the marketplace.

Level 3: Unobservable inputs which are supported by little or no 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 Note 11)

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 are not 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 December 31, 2023 the Company’s cash and cash equivalents balance within money market accounts was in excess of the U.S. federally insured limits by $4.1 million. The Company has not 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 of three months or less at the time of initial purchase to be cash equivalents, including balances held in the Company’s money market accounts. The Company maintains its cash and cash equivalents with financial institutions, in which balances from time to time may exceed the U.S. federally insured limits. The objectives of the Company’s cash management policy are to safeguard and preserve funds to maintain liquidity sufficient to meet the Company’s cash flow requirements, and to attain a market rate of return.

Revenue Recognition

The Company accounts for revenue under ASC 606, Revenue for Contract with Customers (“ASC 606”) or other accounting standards for revenue not derived from customers. Arrangements may include 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 may include licenses to intellectual property and research and development services. When such contractual arrangements are determined to be accounted for in accordance with ASC 606, 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.

The License Agreement with Alvogen as further discussed in Note 6 below is accounted for in accordance with ASC 606. In accordance with ASC 606, 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 ASC 606, it performs the following five steps:

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

ii. identify the performance obligations in the contract;

iii. determine the transaction price;

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

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

The Company only applies the five-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 ASC 606, 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 may provide 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 are not 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 may be fixed, variable, or a combination of both. At contract inception for arrangements that include variable consideration, the Company estimates the probability and

115

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 will not occur when the uncertainty associated with the variable consideration is subsequently resolved.

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

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

The Company’s revenue arrangements 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 Company first 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 would not 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.

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 is incurring research costs in association with the Alvogen agreement. After the First Milestone Payment (as defined in Note 6 below), the Company will be reimbursed for certain costs incurred related to reasonable and documented out-of-pocket costs for clinical and non-clinical development activities. The Company will recognize revenue for the reimbursed costs when the First Milestone Payment contingencies have been achieved and the Company has an enforceable claim to the reimbursed costs.

See Note 6, “Alvogen Licensing Agreement”, for further information on the application of ASC 606 to the License Agreement.

Research and Development Costs

The Company’s research and development expenses consist 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

116

Table of Contents

NRX PHARMACEUTICALS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

for goods and services that will be used in future research and development activities are expensed when the activity has been performed or when the goods have been received.

Non-cancellable Contracts

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

Convertible Note Payable

As permitted under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 825, Financial Instruments (“ASC 825”), the Company elects to account for its convertible promissory note, which meets the required criteria, at fair value at inception and at each subsequent reporting date. Subsequent changes in fair value are recorded as a component of non-operating loss in the consolidated statements of operations. The portion of total changes in fair value of the convertible note 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 Consolidated Statements of Operations and Comprehensive Loss. As a result of electing the fair value option, direct costs and fees related to the convertible promissory notes are expensed as incurred.

The Company estimates the fair value of the convertible note payable using a Monte Carlo simulation model, which uses as inputs the fair value of our common stock and estimates for the equity volatility and volume volatility of our common stock, the time to expiration (i.e. expected term) of the convertible note, the risk-free interest rate for a period that approximates the time to expiration, and probability of default. Therefore, we estimate our expected future equity and volume volatility based on the historical volatility of both our common stock price and common stock trading volume 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 mandatory and potential accelerated redemptions beginning six months from the issuance date. 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. Probability of default is estimated using Bloomberg's Default Risk function which uses our financial information to calculate a default risk specific to the Company. Interest expense is included within the fair value of the convertible note payable. Management believes those assumptions are reasonable but if these assumptions change, it could materially affect the fair value.

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 consolidated statements of operations 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 ASC 480, Distinguishing Liabilities from Equity

117

Table of Contents

NRX PHARMACEUTICALS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, 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 do not 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 fair value of the Private Placement Warrants (as defined below) was estimated using a Black Scholes valuation approach and the fair value of the Substitute Warrants (as defined below) was estimated using a modified Black Scholes valuation approach which applies a probability factor based on the probabilities of achieving earnout cash milestone and/or earnout shares milestone at each reporting period (see Notes 9 and 11).

Modification of Warrants

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 ASC 480, Distinguishing Liabilities from Equity, the Company’s Series A Preferred Stock is classified as permanent equity as it is not mandatorily redeemable upon an event that is considered outside of the Company’s control. Further, in accordance with ASC 815-40, Derivatives and Hedging – Contracts in an Entity’s Own Equity, the Series A Preferred Stock does not meet any of the criteria that would preclude equity classification. The Company concluded that the Series A Preferred Stock is 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 were not bifurcated as a derivative under ASC 815.

Income Taxes

Income taxes are recorded in accordance with ASC 740, Income Taxes (“ASC 740”), 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 than not that some or all of the deferred tax assets will not 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 than not be realized assuming examination by the taxing authority. The determination as to whether the tax benefit will more likely than not 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

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.

6. Alvogen Licensing Agreement

On June 2, 2023, the Company entered into the License Agreement with Alvogen. The Company and Alvogen are referred to below individually as a “Party” and collectively as the “Parties.”

License Grant

Under the License Agreement, the Company granted Alvogen an exclusive (even as to the Company and its affiliates) worldwide, transferable and sublicensable license under certain intellectual property (including patents, know-how and trademarks) owned or controlled by the Company to develop (with certain limitations), manufacture, and commercialize the Company’s candidate therapeutic product, NRX-101, for the treatment of bipolar depression with suicidality. The term of the license is, on a country-by-country basis, 20 years from the first commercial sale of NRX-101 in such country, extendable by Alvogen for a two-year period upon its request made prior to the expiration of such 20-year period. During the term of the License Agreement, the Parties agree (on behalf of themselves and their affiliates) not to research, develop, seek or obtain any regulatory approval for the manufacturing, marketing, sale, or other commercialization of any product containing a fixed dose combination of D-cycloserine and lurasidone in the treatment of bipolar depression with suicidality, nor to authorize or assist (including by investing in or otherwise providing funding to) any third party to do so.

During the term, the Company is permitted to develop additional products containing D-cycloserine in combination with one or more other active antidepressant or antipsychotic ingredients for use outside of the field of treatment of bipolar depression with suicidality, such as in post-traumatic stress disorder (PTSD) or chronic pain in depression, in which case, if the Company wishes to license rights to develop or commercialize such additional products or indications, Alvogen has a right of first negotiation to obtain such a license.

Term and Termination

The License Agreement will remain in force until the earlier to occur of (i) 20 years following the first commercial sale of NRX-101 on a country-by-country basis (which may be extended for a two-year period at Alvogen’s request), and (ii) the date that the agreement is terminated under its early termination provisions. Early termination grounds include, subject to applicable cure periods, a material breach of agreement by the other Party, the bankruptcy or insolvency of the other Party, or a party’s reasonable belief that there is an unacceptable risk for harm in humans based upon preclinical safety data or the observation of serious adverse effects in humans.

In addition, Alvogen has the right to early termination if (i) the phase 2 study relating to NRX-101 is not completed and/or a successful read out from the study does not occur by March 31, 2024, or (ii) there is no completion of a Type B meeting with the FDA by March 31, 2024. Alvogen may also terminate upon sixty (60) days’ prior written notice to the Company at any time after the First Milestone Payment (as defined below) has been made. The Company also has the right to
