NOTES TO CONDENSED FINANCIAL STATEMENTS

Note 1. Organization and description of business operations

PaxMedica, Inc. (the “Company”) is a clinical stage biopharmaceutical company organized as a Delaware limited liability company on April 5, 2018 (“Inception”) to focus on the development of drug candidates for the treatment of autism spectrum disorder (ASD), Fragile X syndrome tremor-ataxia (FXTAS) and Human African Trypanosomiasis (HAT).

Initial Public Offering

On August 9, 2022, the Company entered into an underwriting agreement relating to the public offering of its common stock, par value $0.0001 per share. The Company agreed to sell 1,545,454 shares of its common stock to the underwriters, at a purchase price per share of $4.83 (the offering price to the public of $5.25 per share minus the underwriters’ discount), pursuant to the Company’s registration statement on Form S-1 (File No. 333-239676), as amended, under the Securities Act of 1933, that was filed by the Company under Rule 462(b) under the Securities Act. The Company also granted the underwriters a 45-day option to purchase up to 231,818 additional shares of common stock to cover over-allotments. On August 30, 2022, the Company received net proceeds from its public offering of approximately $6.0 million, net of underwriter fees and commissions of approximately $0.8 million, and offering costs of approximately $1.4 million. In connection with its public offering the Company issued 108,181 warrants to purchase shares of the Company’s common stock with an exercise price of $6.5625 per share.

Going concern, liquidity and capital resources

The Company has no product revenues, incurred operating losses since inception, and expects to continue to incur significant operating losses for the foreseeable future and may never become profitable. The Company had an accumulated deficit of approximately $28.5 million at September 30, 2022, a net loss of approximately $9.6 million, and approximately $3.0 million of net cash used in operating activities for the nine months ended September 30, 2022.

2022 Notes

During the second and third quarters of 2022, the Company entered into senior secured convertible promissory notes (the “2022 Notes”) with a principal balance totaling approximately $1.5 million. The 2022 Notes contain an original issue discount totaling $0.3 million and the Company received net proceeds of approximately $1.2 million (See Note 6).

Series X Preferred Stock

On August 2, 2022, the Company issued 3,200 shares of Series X preferred stock, par value $0.0001 per share at a purchase price of $100 per share. The Company received net proceeds of approximately $0.3 million, net of fees. (See Note 8).

Going Concern

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

The Company’s future liquidity and capital funding requirements will depend on numerous factors, including:

● its ability to raise additional funds to finance its operations;

● the outcome, costs and timing of clinical trial results for the Company’s current or future product candidates;

● the emergence and effect of competing or complementary products;

6

PAXMEDICA, INC.

NOTES TO CONDENSED FINANCIAL STATEMENTS

● its ability to maintain, expand and defend the scope of its intellectual property portfolio, including the amount and timing of any payments the Company may be required to make, or that it may receive, in connection with the licensing, filing, prosecution, defense and enforcement of any patents or other intellectual property rights;

● its ability to retain its current employees and the need and ability to hire additional management and scientific and medical personnel; and

● the terms and timing of any collaborative, licensing or other arrangements that it has or may establish.

The Company will likely need to raise substantial additional funds through one or more of the following: issuance of additional debt or equity, or the completion of a licensing transaction for one or more of the Company’s pipeline assets. If the Company is unable to maintain sufficient financial resources, its business, financial condition and results of operations will be materially and adversely affected. This could affect future development and business activities and potential future clinical studies and/or other future ventures. Failure to obtain additional equity or debt financing will have a material, adverse impact on the Company’s business operations. There can be no assurance that the Company will be able to obtain the needed financing on acceptable terms or at all. Additionally, equity or debt financings will likely have a dilutive effect on the holdings of the Company’s existing stockholders. Accordingly, there are material risks and uncertainties that raise substantial doubt about the Company’s ability to continue as a going concern for the next twelve months from the issuance of these condensed financial statements. The accompanying condensed financial statements do not include any adjustments that result from the outcome of these uncertainties.

The COVID-19 global pandemic has been unprecedented and unpredictable, is likely to continue to result in significant national and global economic disruption, which may adversely affect our business. Based on the Company’s current assessment, the Company does not expect any material impact on its long-term development timeline and its liquidity due to the worldwide spread of the COVID-19 virus. However, the Company is continuing to assess the effect on its operations by monitoring the spread of COVID-19 and the resulting global pandemic and the actions implemented to combat the virus throughout the world.

Note 2. Significant accounting policies

Basis of presentation

The accompanying unaudited condensed financial statements are presented in U.S. dollars and in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP. In the opinion of management, the unaudited condensed financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the periods presented. Operating results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected through December 31, 2022.

The accompanying unaudited condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the registration statement on Form S-1/A filed by the Company with the SEC on August 8, 2022.

Use of estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. The most significant estimates in the Company’s condensed financial statements relate to the valuation of convertible notes, valuation of warrants, valuation of the Simple Agreement For Equity (“SAFE”)  liability and valuation of equity-based awards. 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 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.

PAXMEDICA, INC.

NOTES TO CONDENSED FINANCIAL STATEMENTS

Cash, cash equivalents and short-term investments

The Company considers all highly liquid investments with an original maturity of three months or less at the date of acquisition to be cash equivalents. As of September 30, 2022 and December 31, 2021, the Company had no cash equivalents or short-term investments.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash. The Company maintains its cash high credit quality financial institutions, which may at times, be in excess of federal insured limits. The Company believes it is not exposed to any significant losses due to credit risk on cash.

Fair value of financial instruments

The Company accounts for financial instruments under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 820 (“ASC 820”), Fair Value Measurements. This statement defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. To increase consistency and comparability in fair value measurements, ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels as follows:

Level 1 - quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2 - observable inputs other than Level 1, quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, and model-derived prices whose inputs are observable or whose significant value drivers are observable; and

Level 3 - assets and liabilities whose significant value drivers are unobservable.

Observable inputs are based on market data obtained from independent sources, while unobservable inputs are based on the Company’s market assumptions. Unobservable inputs require significant management judgment or estimation. In some cases, the inputs used to measure an asset or liability may fall into different levels of the fair value hierarchy. In those instances, the fair value measurement is required to be classified using the lowest level of input that is significant to the fair value measurement. Such determination requires significant management judgment. During the nine months ended September 30, 2022, the Company issued certain of the 2022 Notes and warrants in connection with the 2022 Notes. The 2022 Notes and warrants were classified as liabilities and measured at fair value on the issuance date, with changes in fair value recognized as other expense on the statements of operations and disclosed in the condensed financial statements During the year ended December 31, 2021, the Company entered into its SAFE agreement and classified the SAFE as a liability measured at cost on the issuance date, with changes in fair value recognized as other income on the statement of operations. The carrying amounts of the Company’s financial assets and liabilities, such as accounts payable, approximate fair value due to the short-term nature of these instruments.

Convertible Notes

In accordance with Accounting Standards Codification 825, Financial Instruments (“ASC 825”), the Company has elected the fair value option for recognition of its 2022 Notes. In accordance with ASC 825, the Company recognizes these 2022 Notes at fair value with changes in fair value recognized in the condensed statements of operations. The fair value option may be applied instrument by instrument, but it is irrevocable. As a result of applying the fair value option, direct costs and fees related to the convertible notes were recognized in general and administrative expense. Accrued interest for the 2022 Notes has been included in the change in fair value of convertible notes in the condensed statements of operations.

Warrant Liability

The Company accounts for certain common stock warrants outstanding as a liability at fair value and adjusts the instruments to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s statements of operations. The fair value of the warrants issued by the Company have been estimated using the Monte Carlo simulation. As of September 30, 2022, there are no warrant liabilities (See Note 3).

Simple Agreement for Future Equity

The Company accounts for a SAFE as a liability at fair value and adjusts the instrument to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until a triggering event, equity financing or a liquidity/dissolution occurs, and any change in fair value is recognized in the Company’s statements of operations. The fair value of the SAFE has been estimated using the Backsolve method which utilizes the Option Pricing Method. As of September 30, 2022, the SAFE liability has been converted to 100,000 shares of Series X preferred stock (See Note 8).

Research and development

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 expensed when the activity has been performed or when the goods have been received rather than when the payment is made.

Accrued Outsourcing Costs

Substantial portions of the Company’s preclinical studies and clinical trials are performed by third-party laboratories, medical centers, contract research organizations and other vendors (collectively “CROs”). These CROs generally bill monthly or quarterly for services performed, or bill based upon milestone achievement. For preclinical studies, the Company accrues expenses based upon estimated percentage of work completed and the contract milestones remaining. Clinical trial costs are a significant component of research and development expenses and include costs associated with third-party contractors. The Company outsources a substantial portion of its clinical trial activities, utilizing external entities such as CROs, independent clinical investigators, and other third-party service providers to assist the Company with the execution of its clinical studies. For each clinical trial that the Company conducts, certain clinical trial costs are expensed immediately, while others are expensed over time based on the number of patients in the trial, the attrition rate at which patients leave the trial, and/or the period over which clinical investigators or CROs are expected to provide services. The Company’s estimates depend on the timeliness and accuracy of the data provided by the CROs regarding the status of each program and total program spending. The Company periodically evaluates the estimates to determine if adjustments are necessary or appropriate based on information it receives.

Stock-Based Compensation

The Company expenses stock-based compensation to employees, non-employees and board members over the requisite service period based on the estimated grant-date fair value of the awards and actual forfeitures. 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. All stock-based compensation costs are recorded in general and administrative costs in the statements of operations.

Loss Per Share

Basic net loss per share (“EPS”) of common stock is computed by dividing net loss allocated to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity.

PAXMEDICA, INC.

NOTES TO CONDENSED FINANCIAL STATEMENTS

The Company’s common stock equivalents have been excluded from the computation of diluted loss per share for the three and nine months ended September 30, 2022 and 2021, as the effect would be to reduce the loss per share. Therefore, the weighted average common stock outstanding used to calculate both basic and diluted loss per share is the same for the three and nine months ended September 30, 2022 and 2021.

The following securities were excluded from the computation of diluted net loss per share attributable to common shareholders for the nine months ended September 30, 2022 and 2021, because including them would have been anti-dilutive:

	September 30,
	2022	2021
Preferred stock	—	1,557,435
Series X preferred stock	863,162	—
Unvested restricted stock units	1,582,220	1,377,999

SAFE investment	—	414,808
Convertible notes	37,259	—
Total	3,070,138	4,384,418

Income taxes

ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim period, disclosure and transition. Based on the Company’s evaluation, it has been concluded that there are no significant uncertain tax positions requiring recognition in the Company’s condensed financial statements. The Company believes that its income tax positions and deductions would be sustained on audit and does not anticipate any adjustments that would result in material changes to its financial position.

Recent accounting pronouncements

In August 2020, the FASB issued ASU No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. This ASU is effective for annual reporting periods beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. This update permits the use of either the modified retrospective or fully retrospective method of transition. The Company adopted this standard on January 1, 2022, and the adoption did not have a material impact on the Company’s condensed financial statements or disclosures.

In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU reduces diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options (for example, warrants) that remain equity classified after modification or exchange. This ASU provides guidance for a modification or an exchange of a freestanding equity-classified written call option that is not within the scope of another Topic. It specifically addresses: (1) how an entity should treat a modification of the terms or conditions or an exchange of a freestanding equity-classified written call option that remains equity classified after modification or exchange; (2) how an entity should measure the effect of a modification or an exchange of a freestanding equity-classified written call option that remains equity classified after modification or exchange; and (3) how an entity should recognize the effect of a modification or an exchange of a freestanding equity-classified written call option that remains equity classified after modification or exchange. This ASU will be effective for all entities for fiscal years beginning after December 15, 2021. An entity should apply the amendments prospectively to modifications or exchanges occurring on or after the effective date of the amendments. Early adoption is permitted, including adoption in an interim period. The Company adopted this standard on January 1, 2022, and the adoption did not have a material impact on the Company’s condensed financial statements or disclosures.

Note 3. Fair Value Measurements

Convertible Notes

During the second and third quarters of 2022, the Company issued the 2022 Notes. The fair value of the 2022 Notes on the issuance dates and as of September 30, 2022 were estimated using a Monte Carlo simulation to capture the path dependencies intrinsic to their terms. The significant unobservable inputs used in the fair value measurement of the Company’s convertible notes are the common stock price, volatility, and risk-free interest rates. Significant changes in these inputs may result in significantly lower or higher fair value measurement. The Company elected the fair value option when recording its 2022 Notes (See Note 2) and the notes were classified as liabilities and measured at fair value on the issuance date, with changes in fair value recognized as other income (expense) on the statements of operations and disclosed in the condensed financial statements. On August 26, 2022, two holders of the 2022 Notes converted their notes to 238,094 shares of the Company’s common stock and one holder of the 2022 Notes converted its note to 2,555 shares of Series X preferred stock.

A summary of significant unobservable inputs (Level 3 inputs) used in measuring the 2022 Notes upon the issuance dates, conversion dates and during three and nine months ended September 30, 2022 is as follows:

					Three months
			August 3, 2022 -		ended September		Nine months ended

Simple Agreement for Future Equity

On March 19, 2021, the Company entered into a SAFE agreement with an investor. At issuance date, the Company classified the cash received of $5.0 million as a liability, with changes in fair value recognized as other income (expense) on the statements of operations and disclosed in the condensed financial statements (See Note 5). On August 2, 2022 the SAFE was converted to 100,000 shares of Series X preferred stock (See Note 8).

A summary of significant unobservable inputs (Level 3 inputs) used in measuring the SAFE on the conversion date of August 2, 2022, and the period January 1, 2022 through August 2, 2022 is as follows:

Warrants

During the nine months ended September 30, 2022, the Company issued 195,140 common stock warrants in connection with its 2022 Notes (See Note 6). During the year ended December 31, 2020, the Company issued 1,034,176 common stock warrants in association with its 2020 convertible notes (the “2020 Notes”) issued during 2020. The warrants were classified as liabilities and measured at fair value on the grant date, with changes in fair value recognized as other income (expense) on the statements of operations and disclosed in the condensed financial statements.

On August 26, 2022, 750,000 warrants issued in connection with the 2020 Notes were exchanged for 350,000 shares of common stock and 1,250 shares of Series X preferred stock (see below). On August 26, 2022, 479,316 liability classified warrants were reclassified to equity. As of September 30, 2022, there are no liability classified warrants.

Warrant Exchange

On August 3, 2022, the Company entered into a warrant exchange agreement (the “Warrant Exchange Agreement”) with a holder of certain warrants to purchase the Company’s common stock. The warrants were issued in connection with the Company’s 2020 Notes. Pursuant to the Warrant Exchange Agreement, the Company exchanged 750,000 warrants for 350,000 shares of common stock and 1,250 shares of Series X preferred stock at the consummation of the Company’s initial public offering (See Note 8).

A summary of significant unobservable inputs (Level 3 inputs) used in measuring warrants on issuance date, August 26, 2022, and during the period January 1, 2022 through August 26, 2022, is as follows:

					January 1 2022 -
	July 2022		August 26, 2022		August 26, 2022
Dividend yield	0	%	0	%	0	%
Expected price volatility	57.0	%	57.0	%	57.0%- 105.0	%

Expected term (in years)	5.0		0.1-4.9		0.1-4.0

Significant changes in the expected price volatility and expected term would result in significantly lower or higher fair value measurement of the warrants, respectively.

The following tables classify the Company’s liabilities measured at fair value on a recurring basis into the fair value hierarchy as of September 30, 2022 and December 31, 2021:

	Fair value measured at September 30, 2022

Warrant liability	$	4,516,485	$	—	$	—	$	4,516,485

For the three and nine months ended September 30, 2022, there was a change of approximately $3.3 million and $1.8 million in Level 3 liabilities measured at fair value, respectively.

The fair value of the convertible notes may change significantly as additional data is obtained, impacting the Company’s assumptions used to estimate the fair value of the liabilities. In evaluating this information, considerable judgment is required to interpret the data used to develop the assumptions and estimates. The estimates of fair value may not be indicative of the amounts that could be realized in a current market exchange. Accordingly, the use of different market assumptions and/or different valuation techniques may have a material effect on the estimated fair value amounts, and such changes could materially impact the Company’s results of operations in future periods.

Note 5. Simple Agreement for Future Equity (“SAFE”)

During the year ended December 31, 2021, the Company entered into a SAFE with an investor, and received proceeds of $5.0 million. Under the terms of the SAFE, the investor has the right to participate in future equity financings of the Company.

The number of shares to be received by the SAFE investor was based on a 50% discount of the pricing in the triggering equity financing and includes a post money valuation cap of $150.0 million. In a liquidity or dissolution event, the investors right to receive cash out was junior to payment of outstanding indebtedness and creditor claims, on par for other SAFE agreements and/or preferred stock, and senior to payments for common stock. The SAFE had no interest rate or maturity date, the SAFE investor had no voting rights prior to conversion, and if the Company paid a dividend on outstanding shares of common stock while the SAFE was outstanding, the SAFE investor would have received the same dividend.

On August 2, 2022, the fair value of the SAFE was approximately $4.7 million and the SAFE was converted into 100,000 shares of Series X preferred stock. During the three and nine months ended September 30, 2022, the Company recognized a $5.3 million loss on conversion of the SAFE (See Note 8).

Note 6. Convertible promissory notes

During the second and third quarters of 2022, the Company entered into its 2022 Notes with a principal balance totaling approximately $1.5 million. The 2022 Notes contain an original issue discount totaling $0.2 million and the Company received net proceeds of approximately $1.2 million (net of financing fees of approximately $0.1 million). The 2022 Notes bear interest at 10% per annum and mature 12 months from the issuance date. The notes are secured by all assets and personal property of the Company. The note holders have the right to convert all or any portion of the outstanding principal balance and accrued interest into shares of the Company’s common stock, up to a beneficial ownership limitation of 9.99% of the number of shares of common stock outstanding at the time of conversion. The per share conversion price is equal to the lessor of (i) $7.00 or (ii) 80% of the qualified offering price of the Company’s common stock resulting from the listing for trading of its common stock on a qualified exchange. In connection with the notes, the Company issued common stock warrants to purchase 195,140 shares of the Company’s common stock. The warrants have an exercise price of the lessor of (i) $7.00 or (ii) 80% of the qualified offering price and expire five years from the issuance date. As a result of the issuance of the common stock warrants, the exercise price of the Company’s existing warrants was adjusted to an exercise of $3.00 per share.

On August 26, 2022, upon the consummation of the Company’s initial public offering, the conversion price of the 2022 Notes and the exercise price of the warrants is calculated at 80% of $5.25 per share (the offering price) or $4.20 per share.

On August 3, 2022, the Company entered into a conversion agreement with certain holders of the 2022 Notes, pursuant to which the holders agreed to convert $1.0 million of the principal balance at the consummation of the Company’s initial public offering at the conversion price of $4.20 per share. On August 26, 2022, the holders of the 2022 Notes converted the notes fair value of approximately $1.2 million to 238,094 shares of the Company’s common stock.

On August 3, 2022, the Company entered into a conversion agreement with an additional holder of the 2022 Notes, pursuant to which the holder agreed to convert $255,555 of the principal balance at the consummation of the Company’s initial public offering into 2,555 shares of Series X preferred stock. On August 26, 2022, the note holder converted the notes fair value of $0.3 million to 2,555 shares of Series X preferred stock (See Note 8).

As of September 30, 2022, the outstanding principal balance of the 2022 Notes was approximately $0.2 million.

For the nine months ended September 30, 2022, the Company recorded a loss on issuance of debt of $0.4 million, and a fair value loss of $0.25 million that is included in the change in fair value of notes, in the accompanying condensed statements of operations. The Company recognized interest expense as a component of the change in fair value of the notes during the nine months ended September 30, 2022 (See Note 2).

Vested	(11,780)	$	5.26
Unvested as of September 30, 2022	1,582,220	$	5.25

On May 15, 2022, the Company granted 35,333 restricted stock units (RSUs) with a fair value of approximately $0.2 million to a member of its board of directors. The RSUs are subject to service conditions (vesting of 33.34% on August 26, 2022, the consummation date of the Company’s initial public offering, with the remaining units vesting 66.66% over the next two calendar years on each three-month anniversary thereafter).

On January 1, 2022, the Company granted 1,342,667 RSUs with a fair value of approximately $14.6 million to employees, officers and directors of the Company. The RSUs are subject to service conditions (vesting of 33.34% on May 1, 2022, with the remaining units vesting on each three-month anniversary thereafter) and performance conditions in the form of a liquidity event. Vesting of the RSUs is subject to all grantees continuous service with the Company, and no vesting shall occur if the Company has not completed a Qualified Offering or a Change of Control on or before the vesting date. In the event that neither a Qualified Offering nor a Change of Control has occurred prior to December 31, 2022, then all RSUs shall be forfeited for no consideration. Because a Qualified Offering or Change of Control is not considered probable of achievement until consummation, compensation cost measured at the grant date is not recognized until such event occurs.

During the nine months ended September 30, 2022, 291,500 RSU’s (granted on January 1, 2022) were forfeited due to terminations of two of the Company’s employees and two of its board members.

In August 2022, the Company modified the remaining 1,051,167 RSUs granted on January 1, 2022 to provide that 33.34% of each of those RSUs would vest on May 1, 2022, with an additional 8.3325% of each grant vesting each quarter thereafter, provided that if neither (i) the expiration of the 6-month period following an initial public offering nor (ii) a change in control has occurred prior to the applicable vesting date, any RSUs that would have vested thereunder shall not vest until such expiration of the 6-month period following an initial public offering or change in control occurs (provided further that if neither an initial public offering nor a change in control occurs on or prior to December 31, 2022, then all of the related RSUs will be forfeited). Vesting in all cases generally is subject to the grantee’s continued employment with the Company or a subsidiary thereof on the applicable vesting date. This improbable to improbable modification resulted in a new measurement of compensation cost based on the underlying fair value of the Company’s common stock on the date of the modification of approximately $5.5 million.

On August 26, 2022, the Company consummated its initial public offering and based on the modification above, 33.34% of each of the remaining 1,051,167 RSU’s would vest on February 26, 2023, with an additional 8.3325% of each grant vesting each quarter thereafter.

On July 16, 2022, the Company granted 15,000 RSUs to its Chief Financial Officer with a fair value of approximately $0.1 million, all of which vest December 31, 2022. In August 2022, the Company granted 492,500 RSUs with a fair value of approximately $2.6 million to certain officers, directors and employees, one-third of which vest on the one-year anniversary of the Company’s initial public offering, with the remaining restricted stock units vesting on a quarterly basis over the following two years.

NOTES TO CONDENSED FINANCIAL STATEMENTS

On December 22, 2020, the Company granted 896,583 RSUs with a fair value of approximately $6.3 million to its officers and directors, in exchange for 787,499 vested and unvested stock options. The RSUs are subject to service conditions (vesting of 33.34% on May 1, 2021, with the remaining units vesting on each three-month anniversary, thereafter, fully vesting on May 1, 2023) and performance conditions in the form of a liquidity event. Vesting of the RSUs is subject to all grantees continuous service with the Company, and no vesting shall occur if the Company has not completed a Qualified Offering or a Change of Control on or before the vesting date. In the event that neither an IPO nor change in control has occurred prior to December 31, 2021, then all RSUs shall be forfeited for no consideration. Pursuant to the guidance of ASC 718- “Compensation - Stock Compensation”, the exchange of the options for the RSUs was accounted for as a probable (service only vesting) to improbable (performance and service with the performance criteria considered improbable since contingent upon a Qualified Offering or Change of Control) modification. As such, compensation cost for the original awards would be recognized if the awards would have vested pursuant to the original terms. In addition, since the original awards were modified, the incremental cost would be measured as the result of the most recent modification; that is, the fair value of the options after the modification to increase the exercise price to $8.98. This fair value would be compared to the fair value of the RSUs to determine the incremental compensation cost. Incremental compensation cost related to the replacement awards would be recognized only if the modified vesting criteria are achieved.

During the three and nine months ended September 30, 2022, the Company recorded stock-based compensation expense related to the RSUs of approximately $0.9 million, respectively. No stock-based compensation expense related to the RSUs was recognized during the three and nine months ended September 30, 2021. The unamortized stock-based compensation expense related to RSUs as of September 30, 2022 is approximately $7.4 million, which is expected to be recognized over a remaining weighted average vesting period of 1.3 years.

Canceled Stock Options

The Company previously granted options to purchase shares of the Company’s common stock and during the year ended December 31, 2020 these options were canceled. No stock options were outstanding as of September 30, 2022 and December 31, 2021. Compensation cost related to the canceled stock options of $4.3 million will continue to be recognized over the original vesting criteria.

During the three months ended September 30, 2022 and 2021, the Company recorded stock-based compensation expense related to the canceled stock options of approximately $0.1 million and $0.3 million, respectively. During the nine months ended September 30, 2022 and 2021, the Company recorded stock-based compensation expense related to the canceled stock options of approximately $0.45 million and $1.1 million, respectively. The unamortized stock-based compensation expense related to canceled stock options as of September 30, 2022 is approximately $0.3 million.

Overview

We are a clinical stage biopharmaceutical company focusing on the development of anti-purinergic drug therapies (“APT”) for the treatment of disorders with intractable neurologic symptoms, ranging from neurodevelopmental disorders, including autism spectrum disorder (“ASD”), to Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (“ME/CFS”), a debilitating physical and cognitive disorder believed to be viral in origin and now with rising incidence globally due to the long-term effects of SARS-CoV-2 (“COVID-19”). APTs have been shown to block the effects of excess production and extracellular receptor activity of ATP, which acts as both the main energy molecule in all living cells and a peripheral and central nervous system neurotransmitter via receptors that are found throughout the nervous system. Excess purinergic signaling can offset homeostasis and trigger immune responses that result in localized and systemic increases in inflammatory chemokines and cytokines, ultimately stimulating ATP production. APTs may also impact immunologic and inflammatory mechanisms that may be causing or exacerbating symptoms in these seemingly unrelated disorders, which may be caused in part by similar mechanisms of ATP overproduction.

One of our primary points of focus is currently the development and testing of our lead program, PAX-101, an intravenous formulation of suramin, in the treatment of ASD and the advancement of the clinical understanding of using that agent against other disorders such as ME/CFS and Long COVID-19 Syndrome (“LCS”), a clinical diagnosis in individuals who have been previously infected with COVID-19.

In February 2021, we announced positive topline data from our Phase 2 dose-ranging clinical trial evaluating PAX-101 (commonly known as intravenous suramin) for the treatment of the core symptoms of ASD, as described in more detail below. We also intend to submit data to support a New Drug Application (an “NDA”) for PAX-101 under the U.S. Food and Drug Administration’s (the “FDA”) Tropical Disease Priority Voucher Program for the treatment of Human African Trypanosomiasis, a fatal parasitic infection commonly known as African sleeping sickness (“HAT”), leveraging suramin’s historical use in treating HAT outside of the United States. We have exclusively licensed clinical data from certain academic or international government institutions to potentially accelerate PAX-101’s development plans in the United States through this regulatory program and seek approval in the United States for the treatment of East African HAT, which is caused by the parasite Trypanosome brucei rhodesiense, as early as 2024. We are also pursuing the development of next generation APT product development candidates for neurodevelopmental indications. These candidates include PAX-102, our proprietary intranasal formulation of suramin, as well as other new chemical entities that are more targeted and selective antagonists of particular purine receptor subtypes. We believe our lead drug candidate (suramin), if approved by the FDA, may be a significant advancement in the treatment of ASD and a potentially useful treatment for ME/CFS and LCS.

We have not generated any revenue to date and, through September 30, 2022, we had an accumulated deficit of approximately $28.5 million. To date, we have financed our operations through contributions from our prior members, the issuance of our convertible notes, and the issuance of our Simple Agreement For Equity (“SAFE”) and Series X preferred stock, par value $0.0001 per share (“Series X Preferred Stock”). We expect our expenses to increase significantly in connection with our ongoing activities to develop, seek regulatory approval and commercialization of PAX-101 and our other product candidates. Furthermore, we expect to incur additional costs associated with operating as a public company. Accordingly, we will likely need substantial additional financing to support our continuing operations. We will seek to fund our operations through public or private equity or debt financings or other sources. Adequate additional financing may not be available to us on acceptable terms, or at all. Our failure to raise capital as and when needed would have a negative impact on our financial condition and our ability to pursue our business strategy. We will need to generate significant revenues to achieve profitability, and we may never do so. Accordingly, there are material risks and uncertainties that raise substantial doubt about our ability to continue as a going concern.

Convertible Notes

During the second and third quarters of 2022, we issued our senior secured convertible promissory notes (the “2022 Notes”) with a principal balance totaling approximately $1.5 million. The 2022 Notes contain an original issue discount totaling $0.2 million and we received net proceeds of approximately $1.2 million (net of financing fees of approximately $0.1 million). The 2022 Notes bear interest at 10% per annum and mature 12 months from the issuance date. The 2022 Notes are secured by all assets and personal property of the Company. The note holders have the right to convert all or any portion of the outstanding principal balance and accrued interest into shares of the Company’s common stock, up to a beneficial ownership limitation of 9.99% of the number of shares of common stock outstanding at the time of conversion. The per-share conversion price is equal to 80% of the initial offering price of our common stock, or $4.20 per share (based on the Company’s initial public offering price of $5.25 per share). In connection with the 2022 Notes, the Company issued warrants to purchase 195,140 shares of the Company’s common stock. The warrants have an exercise price of 80% of the initial offering price of our common stock, or $4.20 per share (based on the Company’s initial public offering price of $5.25 per share) and expire five years from the issuance date.

On August 26, 2022, upon the consummation of the Company’s initial public offering, the conversion price of the 2022 Notes and the exercise price of the warrants is calculated at 80% of $5.25 per share (the offering price) or $4.20 per share.

On August 3, 2022, the Company entered into a conversion agreement with certain holders of the 2022 Notes, pursuant to which the holders agreed to convert $1.0 million of the principal balance at the consummation of the Company’s initial public offering at the conversion price of $4.20 per share. On August 26, 2022, the holders of the 2022 Notes converted the notes fair value of approximately $1.2 million to 238,094 shares of the Company’s common stock.

On August 3, 2022, the Company entered into a conversion agreement with an additional holder of the 2022 Notes, pursuant to which the holder agreed to convert $255,555 of the principal balance of the 2022 Notes at the consummation of the Company’s initial public offering into 2,555 shares of Series X preferred stock. On August 26, 2022, the note holder converted the note’s fair value of $0.3 million to 2,555 shares of Series X preferred stock.

As of September 30, 2022, the outstanding principal balance of the 2022 Notes was approximately $0.2 million.

Initial Public Offering

On August 9, 2022, the Company entered into an underwriting agreement relating to the public offering of its common stock. The Company agreed to sell 1,545,454 shares of its common stock to the underwriters, at a purchase price per share of $4.83 (the offering price to the public of $5.25 per share minus the underwriters’ discount), pursuant to the Company’s registration statement on Form S-1 (File No. 333-239676), as amended, under the Securities Act, that was filed by the Company under Rule 462(b) under the Securities Act. The Company also granted the underwriters a 45-day option to purchase up to 231,818 additional shares of common stock to cover over-allotments. On August 30, 2022, the Company received net proceeds from its public offering of approximately $6.0 million, net of underwriter fees and commissions of approximately $0.8 million, and offering costs of approximately $1.4 million. In connection with its public offering the Company issued 108,181 warrants to purchase shares of the Company’s common stock with an exercise price of $6.5625 per share.

Series X Preferred Stock

On August 1, 2022, the Company authorized 500,000 shares of Series X preferred stock. The stated value of the Series X preferred stock is $100 per share. The holders of the Series X preferred stock have no voting rights and are not entitled to dividends. The Series X preferred stock is subject to a beneficial ownership limitation of 9.99% of the number of shares of common stock outstanding at the time of conversion.

On August 2, 2022, the Company issued 3,200 shares of Series X Preferred Stock at a purchase price of $100 per share. The Company received net proceeds of approximately $0.3 million, net of fees. On August 26, 2022, upon the consummation of the Company’s initial public offering, 61,689 shares of the Series X preferred stock were converted into 1,175,000 shares of the Company’s common stock. As of September 30, 2022, 45,316 shares of Series X preferred stock remain outstanding.

Financial Operations Overview

Revenue

To date, we have not generated any revenue. Our ability to generate product revenue, which we do not expect will occur in the near term, if ever, will depend on the successful development and eventual commercialization of our current, and any potential future, product candidates.

Research and Development Expenses

Research and development expenses consist of costs incurred for the development of PAX-101 and our other product candidates, which include:

● the cost of acquiring, developing and manufacturing pre-clinical trial materials;

● costs for consultants and contractors associated with chemistry, manufacturing and controls, or CMCs, pre-clinical activities and regulatory operations;

● expenses incurred under agreements with contract research organizations, or CROs, that conduct our pre-clinical trials; and

● employee-related expenses, including salaries for those employees involved in the research and development process.

Research and development costs are expensed as incurred. Costs for certain activities, such as preclinical studies and clinical trials, are generally recognized based on an evaluation of the progress to completion of specific tasks using information and data provided to us by our vendors and collaborators.

General and Administrative Expense

Our general and administrative expenses include costs associated with our executive, accounting, information technology and human resources functions. These expenses consist principally of payroll, employee benefits, travel, and professional services fees such as consulting, audit, tax and legal fees, and general corporate costs. We expense all general and administrative expenses as incurred.

We expect our general and administrative expenses to increase primarily as a result of costs related to us operating as a public company, such as additional legal, accounting, corporate governance, and investor relations expenses, and directors’ and officers’ insurance premiums.

Fair Value of Restricted Stock Units Granted

On January 1, 2022, the Company granted 1,342,667 restricted stock units, or RSUs, with a fair value of approximately $14.6 million to employees, officers and directors of the Company. The RSUs are subject to service conditions (vesting of 33.34% on May 1, 2022, with the remaining units vesting on each three-month anniversary thereafter) and performance conditions in the form of a liquidity event. Vesting of the RSUs is subject to all grantees continuous service with the Company, and no vesting shall occur if the Company has not completed a Qualified Offering or a Change of Control (each as defined therein) on or before the vesting date. In the event that neither a Qualified Offering nor a Change of Control has occurred prior to December 31, 2022, then all RSUs shall be forfeited for no consideration. Because a Qualified Offering or Change of Control is not considered probable of achievement until consummation, compensation cost measured at the grant date is not recognized until such event occurs.

During the nine months ended September 30, 2022, 291,500 RSU’s (granted on January 1, 2022) were forfeited due to terminations of two of the Company’s employees and two of its board members.

In August 2022, the Company modified the remaining 1,051,167 RSUs granted on January 1, 2022 to provide that 33.34% of each of those RSUs would vest on May 1, 2022, with an additional 8.3325% of each grant vesting each quarter thereafter, provided that if neither (i) the expiration of the 6-month period following an initial public offering nor (ii) a change in control has occurred prior to the applicable vesting date, any RSUs that would have vested thereunder shall not vest until such expiration of the 6-month period following an initial public offering or change in control occurs (provided further that if neither an initial public offering nor a change in control occurs on or prior to December 31, 2022, then all of the related RSUs will be forfeited). Vesting in all cases generally is subject to the grantee’s continued employment with the Company or a subsidiary thereof on the applicable vesting date. This improbable to improbable modification resulted in a new measurement of compensation cost based on the underlying fair value of the Company’s common stock on the date of the modification of approximately $5.5 million.

On August 26, 2022, the Company consummated its initial public offering and based on the modification above, 33.34% of each of the remaining 1,051,167 RSU’s would vest on February 26, 2023, with an additional 8.3325% of each grant vesting each quarter thereafter.

On May 15, 2022, the Company granted 35,333 restricted stock units (RSUs) with a fair value of approximately $0.2 million to a member of its board of directors. The RSUs are subject to service conditions (vesting of 33.34% on August 26, 2022, the consummation date of the Company’s initial public offering, with the remaining units vesting 66.66% over the next two calendar years on each three-month anniversary thereafter).

On July 16, 2022, the Company granted 15,000 RSUs to its Chief Financial Officer with a fair value of approximately $0.1 million, all of which vest December 31, 2022. In August 2022, the Company granted 492,500 RSUs with a fair value of approximately $2.6 million to certain officers, directors and employees, one-third of which vest on the one-year anniversary of the Company’s initial public offering, with the remaining restricted stock units vesting on a quarterly basis over the following two years.

During the three months ended September 30, 2022 and 2021, the Company recorded stock-based compensation expense related to the canceled stock options of approximately $0.1 million and $0.3 million, respectively. During the nine months ended September 30, 2022 and 2021, the Company recorded stock-based compensation expense related to the canceled stock options of approximately $0.5 million and $1.1 million, respectively. The unamortized stock-based compensation expense related to the canceled stock options as of September 30, 2022 is approximately $0.3 million.

During the three and nine months ended September 30, 2022, the Company recorded stock-based compensation expense related to the RSUs of approximately $0.9 million. No stock-based compensation expense related to the RSUs was recognized during the three and nine months ended September 30, 2021. The unamortized stock-based compensation expense related to RSUs as of September 30, 2022 is approximately $7.4 million.

21

Impact of COVID-19

Based on our current assessment, we do not expect any material impact on our long-term development timeline and our liquidity due to the worldwide COVID-19 pandemic. However, the COVID-19 pandemic could adversely impact our clinical trial operations, including our ability to recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19 if an outbreak worsens in their geography, or have other adverse effects on our business, results of operations and financial condition. We are continuing to assess the effect on our operations by monitoring the spread of COVID-19 and the resulting global pandemic and the actions implemented to combat the virus throughout the world.

Operating expenses

General and administrative

General and administrative expenses were approximately $2.4 million and $1.3 million for the three months ended September 30, 2022 and 2021, respectively. The $1.1 million increase in general and administrative expenses was primarily due to increases of $0.8 million of stock-based compensation and $0.5 million for legal and professional fees, offset by a decrease of $0.2 million for bonuses.

Research and Development

Research and development expenses were approximately $0.3 million for the three months ended September 30, 2022 and approximately $0.4 million for the three months ended September 30, 2021. The $0.1 million decrease in research and development expenses was primarily attributable to lower costs incurred in connection with our research activities, including lower costs associated with clinical trials, consultants, clinical trial materials, regulatory filings, facilities, laboratory expenses and other supplies.

Of the $0.3 million in research and development expenses incurred during the three months ended September 30, 2022, $0.3 million was associated with activities related to the HAT indication, and $0.02 million was associated with activities related to the ASD indication. These activities included, but were not limited to, milestone payments in connection with the recently completed ASD trial.

Of the approximately $0.4 million in research and development expenses incurred during the three months ended September 30, 2021, approximately $0.3 million was associated with activities related to the HAT indication, and approximately $0.1 million was associated with activities related to the ASD indication. These activities included regulatory advisory services and IV formulation work for HAT as well as work related to our ASD clinical trial.

The estimated aggregate costs expected to be incurred for the research and development activities relating to the filing of an NDA for HAT and an IND for ASD are approximately $11.5 million, which we expect to fund with the proceeds of our initial public offering and future capital raising activities, if necessary.

General and administrative

General and administrative expenses were approximately $4.1 million and $3.7 million for the nine months ended September 30, 2022 and 2021, respectively. The $0.4 million increase in general and administrative expenses is primarily due to increases of $0.9 million for legal and professional fees, $0.3 million of stock-based compensation, offset by $0.7 million of lower bonus expense and $0.1 million of other operating expenses.

Research and Development

Research and development expenses were approximately $1.55 million for the nine months ended September 30, 2022 and approximately $1.75 million for the nine months ended September 30, 2021. The $0.2 million decrease in research and development expenses was primarily attributable to lower costs incurred in connection with our research activities, including lower costs associated with clinical trials, consultants, clinical trial materials, regulatory filings, facilities, laboratory expenses and other supplies.

Of the $1.55 million in research and development expenses incurred during the nine months ended September 30, 2022, $1.41 million was associated with activities related to the HAT indication, and $0.14 million was associated with activities related to the ASD indication.

Of the approximately $1.8 million in research and development expenses incurred during the nine months ended September 30, 2021, approximately $1.2 million was associated with activities related to the HAT indication, and approximately $0.6 million was associated with activities related to the ASD indication. These activities included regulatory advisory services and IV formulation work for HAT as well as work related to our ASD clinical trial.

The estimated aggregate costs expected to be incurred for the research and development activities relating to the filing of an NDA for HAT and an IND for ASD are approximately $11.3 million, which we expect to fund with the proceeds of our initial public offering and future capital raising activities, if necessary.

Other Expenses, net

Other expense was approximately $4.0 million for the nine months ended September 30, 2022 compared with $11.1 million for the nine months ended September 30, 2021. Other expense of $4.0 million for the nine months ended September 30, 2022 was primarily comprised of a $5.3 million loss on conversion of our SAFE investment to Series X preferred stock, $0.4 million for the loss on issuance of our 2022 Notes and $0.3 million recognized for the change in fair value of our 2022 Notes, offset by $1.9 million recognized for the change in fair value of our warrant liability and $0.2 million for the change in fair value of our SAFE investment. Other expense of $11.1 million for the nine months ended September 30, 2021 was primarily comprised of $4.5 million recognized for the change in fair value of our warrant liability, $3.8 million recognized for the change in fair value of our SAFE liability and $2.8 million of interest expense incurred in connection with our convertible notes.

Liquidity and Capital Resources

We were formed as a Delaware limited liability company on April 5, 2018 and converted into a Delaware corporation on April 15, 2020. As of September 30, 2022, we had an accumulated deficit since inception of approximately $28.5 million. Since inception, we have not generated revenue from product sales and have incurred net losses and negative cash flows from our operations. From inception through September 30, 2022, we have funded our operations through contributions from TardiMed Sciences, LLC (“TardiMed”), the issuance of senior secured convertible promissory notes of approximately $4.2 million, proceeds from the public common stock offering, net of fees, of approximately $6.0 million and our SAFE of $5.0 million.

Convertible Notes

During the second and third quarters of 2022, we issued the 2022 Notes with a principal balance totaling approximately $1.5 million. The 2022 Notes contain an original issue discount totaling approximately $0.2 million and we received net proceeds of approximately $1.3 million. The 2022 Notes bear interest at 10% per annum and mature 12 months from the issuance date. The 2022 Notes are secured by all assets and personal property of the Company. The note holders have the right to convert all or any portion of the outstanding principal balance and accrued interest into shares of the Company’s common stock, up to a beneficial ownership limitation of 9.99% of the number of shares of common stock outstanding at the time of conversion. The per-share conversion price is equal to 80% of the initial offering price, or $4.20 per share (based on the Company’s initial public offering price of $5.25 per share). In connection with the 2022 Notes, the Company issued the warrants to purchase 195,140 shares of the Company’s common stock. The warrants have an exercise price of 80% of the initial offering price, or $4.20 per share (based on the Company’s initial public offering price of $5.25 per share) and expire five years from the issuance date.

On August 26, 2022, upon the consummation of the Company’s initial public offering, the conversion price of the 2022 Notes and the exercise price of the warrants is calculated at 80% of $5.25 per share (the offering price) or $4.20 per share.

On August 3, 2022, the Company entered into a conversion agreement with certain holders of the 2022 Notes, pursuant to which the holders agreed to convert $1.0 million of the principal balance at the consummation of the Company’s initial public offering at the conversion price of $4.20 per share. On August 26, 2022, the holders of the 2022 Notes converted the notes fair value of approximately $1.2 million to 238,094 shares of the Company’s common stock.

On August 3, 2022, the Company entered into a conversion agreement with an additional holder of the 2022 Notes, pursuant to which the holder agreed to convert $255,555 of the principal balance at the consummation of the Company’s initial public offering into 2,555 shares of Series X preferred stock. On August 26, 2022, the note holder converted the note’s fair value of $0.3 million to 2,555 shares of Series X preferred stock.

SAFE

In March 2021, we entered into the SAFE with an investor, pursuant to which we received gross proceeds in an aggregate amount equal to $5.0 million. As of September 30, 2022, the SAFE liability was zero.

24

Series X Preferred Stock

On August 2, 2022, the Company issued 3,200 shares of Series X preferred stock in a private placement, at a purchase price of $100 per share, and received net proceeds of approximately $0.3 million, after deducting expenses (the “Series X Private Placement”). The Series X Private Placement constituted a qualified offering under the terms of the SAFE and the $5.0 million outstanding under the SAFE automatically converted into 100,000 shares of Series X preferred stock.

On August 26, 2022, upon the consummation of the Company’s initial public offering, 61,689 shares of the Series X preferred stock were converted into 1,175,000 shares of the Company’s common stock. As of September 30, 2022, 45,316 shares of Series X preferred stock remain outstanding.

Warrant Exchange Agreement

On August 3, 2022, the Company entered into a warrant exchange agreement (the “Warrant Exchange Agreement”) with a holder of certain warrants to purchase the Company’s common stock. The warrants were issued in connection with the Company’s 2020 Notes. Pursuant to the Warrant Exchange Agreement, on August 26, 2022, the Company exchanged 750,000 warrants for 350,000 shares of its common stock and 1,250 shares of its Series X preferred stock.

Series Seed Preferred Stock

On August 5, 2022, the Company entered into exchange agreements with the holders of the Company’s Series Seed preferred stock, par value $0.0001 per share. The Company and the holders exchanged all shares of outstanding Series Seed preferred stock into 1,557,435 shares of common stock immediately prior to the effectiveness of its registration statement filed in connection with the Company’s initial public offering.

Operating activities

During the nine months ended September 30, 2022, net cash used in operating activities was $3.0 million, which primarily included our net loss of approximately $9.6 million, adjusted for non-cash expenses of approximately $5.3 million including loss on conversion of our SAFE investment of $5.3 million, stock-based compensation of approximately $1.4 million, loss on issuance of debt of $0.4 million recorded in connection with the issuance of our 2022 Notes and the change in fair value of our 2022 Notes of $0.25 million, offset by the change in fair value of our warrant liability of $1.9 million and the change in fair value of our SAFE investment of $0.2 million. The net change in operating assets and liabilities was approximately $1.3 million and was primarily due to increases in accounts payable and accrued expenses of $1.5 million and increases in other assets of $0.2 million.

During the nine months ended September 30, 2021, net cash used in operating activities was approximately $4.3 million which primarily included our net loss of approximately $16.5 million, adjusted for non-cash expenses of approximately $12.2 million, including the change in fair value of our warrant liability of $4.5 million, the change in fair value of our SAFE of $3.8 million, amortization of debt discount of $2.6 million related to our convertible promissory notes, stock-based compensation of $1.1 million, and other expenses of $0.2 million. The net change in operating assets and liabilities was nominal.

Investing Activities

There were no investing activities for the nine months ended September 30, 2022 and 2021.

Financing activities

During the nine months ended September 30, 2022, net cash provided by financing activities was approximately $8.1 million, consisting of proceeds received from our initial public offering of $6.6 million, the issuance of our 2022 Notes and warrants of $1.2 million, and $0.3 million from the issuance of our Series X preferred stock.

During the nine months ended September 30, 2021, net cash provided by financing activities was $4.9 million, consisting of $5.0 million of proceeds received from our SAFE agreement, offset by $0.1 million of payments for offering costs.

25

Funding requirements

As of September 30, 2022, we had a cash balance of approximately $5.6 million. Our financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The 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 might result from the outcome of this uncertainty.

We anticipate incurring additional losses for the foreseeable future and may never become profitable. We expect our expenses to increase in connection with our ongoing activities, particularly as we continue the research and development of product candidates. Furthermore, we expect to continue to incur additional costs as a public company. Accordingly, we will likely need to obtain substantial additional funding. If we are unable to raise capital or otherwise obtain funding when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research and development programs or future commercialization efforts. These factors raise substantial doubt about our ability to continue as a going concern.

We will seek to obtain additional capital through the sale of debt or equity financings or other arrangements such as, collaborations, strategic alliances and licensing arrangements to fund operations; however, there can be no assurance that we will be able to raise needed capital under acceptable terms, if at all. The sale of additional equity securities may dilute existing stockholders and may contain senior rights and preferences compared to currently outstanding shares of common and preferred stock. Debt securities issued or other debt financing incurred may contain covenants and limit our ability to pay dividends or make other distributions to stockholders. If we are unable to obtain such additional financing, future operations would need to be scaled back or discontinued.

Contractual obligations and commitments

As of September 30, 2022, the 2022 Notes outstanding principal balance totals approximately $216,000. The notes bear interest at 10% per annum and mature between April and July 2023.

Off-balance sheet arrangements

We do not have any relationships with unconsolidated entities or financial partnerships, including entities sometimes referred to as structured finance or special purpose entities that were established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. We do not engage in off-balance sheet financing arrangements. In addition, we do not engage in trading activities involving non-exchange traded contracts. We therefore believe that we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in these relationships.

Critical accounting policies and significant judgments and estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of these financial statements requires us 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 U.S. GAAP, we evaluate our estimates and judgments on an ongoing basis. The most significant estimates relate to the valuation of our common stock, SAFE liability and warranty liability, and our election to adopt the fair value option for our convertible notes. 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 materially and adversely from these estimates. To the extent there are material differences between the estimates and actual results, our future results of operations will be affected.

We define our critical accounting policies as those accounting principles that require us to make subjective estimates and judgments about matters that are uncertain and are likely to have a material impact on our financial condition and results of operations, as well as the specific manner in which we apply those principles. While our significant accounting policies are more fully described in Note 2 to our financial statements, we believe the following are the critical accounting policies used in the preparation of our financial statements that require significant estimates and judgments:

26

Stock-Based Compensation

We expense stock-based compensation to employees, non-employees and board members over the requisite service period based on the estimated grant-date fair value of the awards and actual forfeitures. We account 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 determination of the grant date fair value of options using an option pricing model is affected principally by our estimated fair value of shares of our common stock and requires management to make a number of other assumptions, including the expected term of the option, the expected volatility of the underlying shares, the risk-free interest rate and the expected dividend yield. The assumptions used in our Black-Scholes option-pricing model represent management’s best estimates at the time of measurement. These estimates are complex, involve a number of variables, uncertainties and assumptions and the application of management’s judgment, as they are inherently subjective. If any assumptions change, our stock-based compensation expense could be materially different in the future. These assumptions are estimated as follows:

●Fair Value of Common Stock. See the subsection titled “- Fair Value of Common Stock” below.

●Expected Term. The expected term represents the period that our options are expected to be outstanding. We calculated the expected term using the simplified method for options based on the average of each option’s vesting term and the contractual period during which the option can be exercised, which is typically 10 years following the date of grant.

●Expected Volatility. The expected volatility was based on the historical share volatility of several comparable publicly traded companies over a period of time equal to the expected term of the options, as we did not have any trading history to use the volatility of our own common stock. The comparable companies were chosen based on their size, stage in life cycle and area of specialty. We will continue to apply this process until a sufficient amount of historical information regarding the volatility of our own stock price becomes available.

●Risk-Free Interest Rate. The risk-free interest rate was based on the yields of U.S. Treasury securities with maturities appropriate for the term of the award.

●Expected Dividend Yield. We have not paid dividends on our common stock nor do we expect to pay dividends in the foreseeable future. Therefore, we used an expected dividend yield of zero.

Fair Value of Common Stock

Prior to the Company’s initial public offering, there was no public market for our common stock. As such, the estimated fair value of our common stock and underlying stock options has been determined at each grant date by our board of directors, with input from management, based on the information known to us on the grant date.

Beginning in May 2020, we determined the estimated fair value of our common stock using the Hybrid Method, which incorporated the Option Pricing Model (“OPM”) and the Probability Weighted Expected Return Method (“PWERM”), estimating the probability- weighted value across multiple scenarios by using the OPM to estimate the allocation of value within one or more of those scenarios. The Hybrid Method was utilized given there was transparency into one or more near- term potential exits but there existed uncertainty regarding what would occur if the near-term exit plans did not materialize. Under the PWERM, the values of the various equity interests were estimated based upon an analysis of future values for our company, assuming various potential future outcomes. Share value was based upon the probability-weighted present value of expected future investment returns, considering each of the possible future outcomes available to us, as well as the rights of each share class. The future outcomes modeled included an initial public offering, a dissolution or continued operation as a private company until a later exit date. To estimate our total equity value, a combination of the Backsolve Methodology (“backsolving” the implied enterprise value based on the price paid for each new preferred security sold), a discounted cash flow analysis and a guideline publicly traded company method was used for scenario options, based on the fact pattern that existed as of the particular valuation date. After deriving the indicated values of equity under the scenario options, the present value of the class specific equity allocations were calculated. After calculating the present values as applicable to the scenarios, the probability of each scenario occurring was multiplied by the indications of value under each scenario. The sum of the probability-weighted values for our common stock was then divided by our total common stock outstanding as of the relevant valuation date.

27

In addition to considering the results of these third-party valuation reports, our board of directors used assumptions based on various objective and subjective factors, combined with management judgment, to determine the fair value of our common stock as of the grant date, including:

● the prices at which we sold shares of preferred stock and the superior rights and preferences of the preferred stock relative to our common stock at the time of each grant;

● external market conditions affecting the life sciences research and development industry and trends within the industry;

● our stage of development and business strategy;

● our financial condition and operating results, including our levels of available capital resources and forecasted results;

● developments in our business;

● the progress of our research and development efforts;

● equity market conditions affecting comparable public companies; and

● general market conditions and the lack of marketability of our common stock.

Application of these approaches involves the use of estimates, judgment and assumptions that are highly complex and subjective, such as those regarding our expected future revenue, expenses and future cash flows, discount rates, market multiples, the selection of comparable companies and the probability of possible future events. Changes in any or all of these estimates and assumptions or the relationships between the assumptions impact our valuations as of each valuation date and may have a material impact on the valuation of our common stock.

Following the Company’s initial public offering, a public trading market for our common stock has been established and it will no longer be necessary for our board of directors to estimate the fair value of our common stock in connection with our accounting for granted stock options and other such awards we may grant, as the fair value of our common stock will be determined based on the closing price of our common stock as reported on the date of grant.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Convertible Notes

In accordance with Accounting Standards Codification 825, Financial Instruments (“ASC 825”), the Company has elected the fair value option for recognition of its convertible notes. In accordance with ASC 825, the Company recognizes these convertible notes at fair value with changes in fair value recognized in the condensed statements of operations. The fair value option may be applied instrument by instrument, but it is irrevocable. As a result of applying the fair value option, direct costs and fees related to the convertible notes were recognized in general and administrative expense. Accrued interest for the notes has been included in the change in fair value of convertible notes in the condensed statements of operations.

Warrant Liability

We account for certain common stock warrants outstanding as a liability at fair value and adjust the instruments to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in our statements of operations. The fair value of the warrants issued by us have been estimated using the Monte Carlo simulation.

28

Simple Agreement for Future Equity

The Company accounts for a SAFE as a liability at fair value and adjusts the instrument to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until a triggering event, equity financing or a liquidity/dissolution occurs, and any change in fair value is recognized in the Company’s statements of operations. The fair value of the SAFE has been estimated using the Backsolve method which utilizes the Option Pricing Method.

Accrued Outsourcing Costs

Substantial portions of our preclinical studies and clinical trials are performed by third-party laboratories, medical centers, CROs and other vendors. These CROs generally bill monthly or quarterly for services performed, or bill based upon milestone achievement. For preclinical studies, we accrue expenses based upon estimated percentage of work completed and the contract milestones remaining. Clinical trial costs are a significant component of research and development expenses and include costs associated with third-party contractors. We outsource a substantial portion of our clinical trial activities, utilizing external entities such as CROs, independent clinical investigators, and other third-party service providers to assist us with the execution of its clinical studies. For each clinical trial that we conduct, certain clinical trial costs are expensed immediately, while others are expensed over time based on the number of patients in the trial, the attrition rate at which patients leave the trial, and/or the period over which clinical investigators or CROs are expected to provide services. Our estimates depend on the timeliness and accuracy of the data provided by the CROs regarding the status of each program and total program spending. We periodically evaluate the estimates to determine if adjustments are necessary or appropriate based on information it receives.

Research and Development

Research and development expenses consist primarily of salaries, benefits and other related costs, including stock-based compensation, for personnel serving our development functions, and other internal operating expenses, the cost of clinical studies, and the cost of our drug candidate for clinical study. In addition, research and development expenses include payments to third parties for the development of our product candidates and the estimated fair value for the issuance of equity for the license rights to products in development (prior to marketing approval). Our expenses related to clinical trials are primarily related to activities at CROs that design, gain approval for and conduct clinical trials on our behalf. Such amounts are then recognized as an expense as the related goods are delivered or the services are performed.

Recent accounting pronouncements

See Note 2 to our financial statements for a description of recent accounting pronouncements applicable to our financial statements.

Emerging Growth Company and Smaller Reporting Company Status

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act (“JOBS Act”), and we may remain an emerging growth company for up to five years following the completion of our initial public offering. For so long as we remain an emerging growth company, we are permitted and intend to rely on certain exemptions from various public company reporting requirements, including not being required to have our internal control over financial reporting audited by our independent registered public accounting firm pursuant to Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and any golden parachute payments not previously approved and an exemption from compliance with the requirements regarding the communication of critical audit matters in the auditor’s report on financial statements.

29

Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We have elected to avail ourselves of this exemption from new or revised accounting standards and, therefore, we will not be subject to the same new or revised accounting standards as public companies that are not emerging growth companies. As a result of this election, our financial statements may not be comparable to those of companies that are not emerging growth companies.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information otherwise required under this item.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the fiscal quarter ended September 30, 2022, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on this evaluation, our principal executive officer and principal financial officer has concluded that during the period covered by this report, our disclosure controls and procedures were not effective as of September 30, 2022 because of a material weakness in our internal control over accounting for complex financial instruments. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis. Specifically, the Company’s management has concluded that our control around the interpretation and accounting for certain complex features of financial instruments was not effectively designed or maintained. As a result, our management performed additional analysis as deemed necessary to ensure that our financial statements were prepared in accordance with accounting principles generally accepted in the United States of America. Accordingly, management believes that the financial statements included in this Form 10-Q present fairly, in all material respects, our financial position, result of operations and cash flows of the periods presented. Management understands that the accounting standards applicable to our financial statements are complex and has since the inception of the Company benefited from the support of experienced third-party professionals with whom management has regularly consulted with respect to accounting issues. Management intends to continue to further consult with such professionals in connection with accounting matters.

Material Weaknesses in Internal Control over Financial Reporting

In the course of preparing our financial statements for the year ended December 31, 2020 and the period ended March 31, 2022, we identified material weaknesses in our internal control over financial reporting relating to the evaluation of complex financial instruments, including earnings per share. The material weaknesses have not been remediated as of September 30, 2022. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. Our management has concluded that our control around the interpretation and accounting for certain complex instruments issued by the Company was not effectively designed or maintained.

We originally prepared an accounting position paper concluding that Series Seed Preferred Stock should have been classified as mezzanine equity in accordance with ASC 480. Upon further analysis, it was determined that the Series Seed Preferred Stock should have been recorded as permanent equity because certain redemption provisions are within the Company’s control. Therefore, management has concluded that our controls around the interpretation and accounting for our Series Seed Preferred Stock issued was not effectively designed or maintained. Additionally, the original earnings per share calculation did not correctly classify the shares associated with our SAFE investment and our Series Seed Preferred Stock as a separate class of participating securities. Upon further analysis we determined the controls over the calculation of earnings per share resulted in a material weakness.

30

To remediate the above material weaknesses, we intend to develop a remediation plan with assistance from our accounting advisors and have dedicated significant resources and efforts to the remediation and improvement of our internal control over financial reporting. While we have processes to identify and appropriately apply applicable accounting requirements, we plan to enhance our system of evaluating and implementing the complex accounting standards that apply to our financial statements. Our plans at this time include providing enhanced access to accounting literature, research materials and documents, and increased communication among our personnel and third-party professionals with whom we consult regarding complex accounting applications. The elements of our remediation plan can only be accomplished over time, and we can offer no assurance that these initiatives will ultimately have the intended effects. We do not believe that the remediation of these material weaknesses will result in significant incremental cost. However, another significant financial reporting failure or material weakness in internal control over financial reporting could result in substantial cost to remediate and could cause a loss of investor confidence and decline in the market price of our stock.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the fiscal quarter ended September 30, 2022 covered by this report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

31

PART II-OTHER INFORMATION

Item 1. Legal Proceedings

From time to time we may be involved in legal proceedings arising in connection with our business. Based on information currently available, we believe that the amount, or range, of reasonably possible losses in connection with any pending actions against us in excess of established reserves, in the aggregate, is not material to our consolidated financial condition or cash flows. However, losses may be material to our operating results for any particular future period, depending on the level of income for such period.

Item 1A. Risk Factors

You should carefully review and consider the information regarding certain risks and uncertainties facing us that could have a material adverse effect on our business prospects, financial condition, results of operations, liquidity and available capital resources set forth in Part I, Item 1A of the Company’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2022.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Unregistered Sales of Equity Securities

The following list sets forth information as to all securities we have sold during the period covered by this report which were not registered under the Securities Act.

Restricted Stock Units

In July 2022 and August 2022, we granted a total of 507,500 restricted stock units under the PaxMedica Inc. Amended and Restated 2020 Omnibus Equity Incentive Plan to certain of our employees and directors, each of which entitles the holder to one share of our common stock upon settlement of the restricted stock unit.

2022 Convertible Promissory Note Offering and Warrants

Between April and July 2022, we issued the 2022 Notes in an aggregate principal amount of approximately $1.5 million with an interest rate of 10% per annum. The 2022 Notes mature 12 months from the date of issuance, and convert at a conversion price equal to 80% of the initial offering price, or $4.20 per share. In connection with the offering of the 2022 Notes, we issued common stock purchase warrants to purchase up to 195,140 shares of common stock, with an exercise price of 80% of the initial offering price, or $4.20 per share.

Private Placement of Series X Preferred Stock

On August 2, 2022, the Company issued and sold an aggregate of 3,200 shares of our Series X Preferred Stock to a certain “accredited investor” (as defined in Regulation D promulgated under the Securities Act), at a purchase price of $100 per share, for aggregate proceeds of approximately $320,000 and net proceeds to the Company of approximately $300,000, after deducting expenses. Upon the closing of our initial public offering, all outstanding shares of Series X Preferred Stock automatically converted into shares of common stock at the initial offering price, subject to the beneficial ownership restrictions contained in the certificate of designations for the Series X Preferred.

SAFE

In March 2021, we entered into the SAFE with an investor, pursuant to which we received gross proceeds in an aggregate amount equal to $5.0 million. The Series X Private Placement in August 2022 constituted a qualified offering under the terms of the SAFE and the SAFE automatically converted into 100,000 shares of Series X Preferred Stock.

32
