NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Description of the Business

Peak Bio, Inc., together with its fully-owned subsidiaries, Peak Bio Co. Ltd (“Peak Bio Ltd”) and Peak Bio CA, Inc. (the “Company” or “Peak Bio”), is a clinical-stage biotechnology company focused on discovering, developing and delivering innovative therapies for multiple therapeutic areas. The Company has established a portfolio of potential therapies focused on cancer and immunological diseases. The Company’s pipeline includes the PH-1 ADC Platform for oncology, PHP-303 program for genetic disease, liver disease and inflammation, specifically for Alpha-1 antitrypsin deficiency (AATD) and acute respiratory distress syndrome (ARDS) including COVID-19.

Akari Merger Agreement

On March 4, 2024, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Akari Therapeutics, Plc, a public company limited by shares incorporated in England and Wales (“Akari”), and Pegasus Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Akari (“Merger Sub”), pursuant to which, Merger Sub will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly-owned subsidiary of Akari.

Pursuant to the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each issued and outstanding share of the Company’s Common Stock will be converted into the right to receive Akari American Depositary Shares (“Akari ADSs”) representing a number of Akari ordinary shares, par value $0.0001 per share (the “Akari Ordinary Shares”), equal to an exchange ratio calculated in accordance with the Merger Agreement (the “Exchange Ratio”), each such share duly and validly issued against the deposit of the requisite number of Akari Ordinary Shares in accordance with the Deposit Agreement (as defined in the Merger Agreement). The Exchange Ratio will be calculated such that the total number of shares of Akari ADSs to be issued as merger consideration for the Company’s Common Stock will be expected to be, upon issuance, approximately 50% of the outstanding shares of Akari ADSs (provided, certain adjustments to this ratio will be made in respect of the net cash, as determined in accordance with the Merger Agreement, of each of Peak Bio and Akari at the close of business one business day prior to the anticipated consummation of the Merger).

At the Effective Time, each warrant and option to purchase capital stock of the Company outstanding immediately prior to the Effective Time will be exchanged for a warrant or option to purchase a number of Akari ordinary shares or Akari ADSs, as determined by Akari, based on the Exchange Ratio.

Voting Agreements

Concurrently with the Merger Agreement, the Company and Akari entered into voting and support agreements (the “Voting Agreements”) with certain stockholders of the Company (the “Peak Stockholders”) and certain shareholders of Akari (the “Akari Shareholders” and, together with the Peak Stockholders, the “Supporting Holders”). The Supporting Holders have agreed to, among other things, vote their shares in favor of the Merger Agreement and the Merger or the issuance of Akari Ordinary Shares in connection therewith, as applicable, in accordance with the recommendation of the respective boards of directors of Peak Bio and Akari.

Risks and Uncertainties

The Company is subject to a number of risks similar to other companies in its industry, including competition from larger pharmaceutical and biotechnology companies, delays in research and development activities due to lack of financial resources and dependence on key personnel.

Results of operations may be adversely affected by various factors that could cause economic uncertainty and volatility in the financial markets, many of which are beyond the Company’s control. The Company’s business could be impacted by, among other things, downturns in the financial markets or in economic conditions, inflation, increases in interest rates, and geopolitical instability, such as the military conflicts in Ukraine and the Israel-Hamas war. While the Company has not been impacted by the abovementioned risks and uncertainties to date, the Company cannot at this time fully predict the likelihood of one or more of the above events, their duration or magnitude or the extent to which they may negatively impact the Company’s business.

Going Concern

The Company has incurred net losses since inception, and has an accumulated deficit of $40.6 million as of March 31, 2024. The Company incurred net losses of $2.4 million and $6.8 million for the three months ended March 31, 2024 and 2023, respectively. Since April 1, 2024, the Company raised aggregate gross proceeds of approximately $3.5 million from the issuance of May 2024 Convertible Notes (see Note 14). The Company expects to incur significant expenses and operating losses for the foreseeable future as it continues its efforts to identify product candidates and seek regulatory approvals within its portfolio.

The Company will need additional financing to fund its ongoing activities and to close the Merger with Akari. The Company may raise this additional funding through the sale of equity, debt financing or other capital sources, including potential collaborations with other companies or other strategic transactions and funding under government contracts.

The Company may be unable to raise additional funds or enter into other arrangements when needed on favorable terms, or at all. There can be no assurances that other sources of financing will be available. Due to these uncertainties, there is substantial doubt about the Company’s ability to continue as a going concern. The accompanying unaudited condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The unaudited condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or classification of liabilities that might result from the outcome of the uncertainties discussed above.

On January 6, 2023, the Company received a determination letter (the “Determination Letter”) from the Panel to delist the Company’s common stock and warrants from Nasdaq. Nasdaq suspended trading in Company’s common stock and warrants effective at the open of business on January 10, 2023. Following the suspension from Nasdaq, the Company’s securities are trading on the OTC Markets’ “OTC Pink Market” tier, which in turn impacted the Company's ability to raise capital.

Summary of Significant Accounting Policies

For the three months ended March 31, 2024, there have been no changes to the significant accounting policies as disclosed in Note 2 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Consolidated Financial Statements”).

Unaudited Financial Information

The Company’s unaudited condensed consolidated financial statements included herein have been prepared in conformity with accounting principles generally accepted in the United States of America, or GAAP, and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany balances and transactions have been eliminated in consolidation.

In the Company’s opinion, the information furnished reflects all adjustments, all of which are of a normal and recurring nature, necessary for a fair presentation of the financial position and results of operations for the reported interim periods. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure.

The unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2023 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on August 5, 2024 (the “2023 Form 10-K”).

The accompanying consolidated balance sheet as of December 31, 2023 has been derived from the audited balance sheet as of December 31, 2023 contained in the Company’s 2023 Form 10-K. Results of operations for interim periods are not necessarily indicative of the result of operations for a full year.

Use of Estimates

The preparation of condensed consolidated 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 unaudited condensed consolidated financial

statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates include but are not limited to fair value of the Company’s stock, stock-based compensation expense, warrant liability, derivative liability, and discount rates used to establish operating lease liability. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Actual results could differ from those estimates.

Restricted Cash

Restricted cash as of March 31, 2024 and December 31, 2023 consists of $60,000 in a restricted bank account established to secure the Company’s credit cards.

Impairment of Long-lived Assets

Long-lived assets consist primarily of property and equipment, and operating right-of-use assets. The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset is not recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset exceeds the fair value of the assets. Fair value would be assessed using discounted cash flows or other appropriate measures of fair value. No impairment losses were recognized during the three months ended March 31, 2024. The Company recognized an impairment loss on its operating right-of-use assets, totaling $3,513,999 during the three months ended March 31, 2023 (see Note 7).

Net Loss Per Share

The Company computes basic net loss per share attributable to common stockholders by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period, without consideration for potentially dilutive securities.

The Company computes diluted net loss per share after giving consideration to all potentially dilutive common shares resulting from the exercise of options and warrants and the conversion of convertible notes, outstanding during the period determined using the treasury-stock and if-converted methods, as applicable, except where the effect of including such securities would be antidilutive.

The December 2023 Convertible Notes (see Note 10) are contingently convertible notes and are not included for purposes of calculating the number of diluted shares outstanding as the number of dilutive shares is based on a non-market based conversion contingency that had not been met in the reporting periods presented herein.

For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding as inclusion of the potentially dilutive securities would be antidilutive.

The following table sets forth the potentially dilutive securities that have been excluded from the calculation of diluted net loss per share because to include them would be anti-dilutive (in common stock equivalent shares):


	March 31,		December 31,
	2024		2023
Common stock options		1,363,108		1,698,754
Common stock warrants		9,419,352		9,419,352
April 2023 Convertible Notes convertible into common stock		5,127,945		5,493,515

Recently Adopted Accounting Standards

In November 2023, the FASB issued ASU 2023-07, Segment Reporting: Improvements to Reportable Segment Disclosures. This ASU modified the disclosure and presentation requirements primarily through enhanced disclosures of significant segment expenses and clarified that single reportable segment entities must apply Topic 280 in its entirety. This guidance is effective for the Company for the year beginning January 1, 2024, with early adoption permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statement. The Company adopted ASU 2023-07 on January 1, 2024 and the adoption did not have a

material effect on the Company’s consolidated financial statements.

In August 2020, the FASB issued ASU 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” (“ASU 2020-06”), which simplifies the accounting for convertible instruments by removing major separation models required under current U.S. GAAP. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for such exception and simplifies the diluted earnings per share calculation in certain areas. ASU 2020-06 is effective for public business entities that meet the definition of a SEC filer, excluding entities eligible to be smaller reporting companies as defined by the SEC, for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company adopted ASU 2020-06 on January 1, 2024 and the adoption did not have a material effect on the Company’s consolidated financial statements.

Recently Issued Accounting Standards Not Yet Adopted

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The amendments are effective for all public entities for fiscal years beginning after December 15, 2024. Early adoption is permitted and should be applied either prospectively or retrospectively. The Company plans to adopt ASU 2023-09 and related updates on January 1, 2025. The Company is currently evaluating the impact that the updated standard will have on its financial statement disclosures.

There were no other recently issued but not yet effective accounting pronouncements that will have a material effect on the accompanying unaudited condensed consolidated financial statements.

Other noncurrent liabilities of $230,650 as of December 31, 2023, are related to the founder and director's forwent salary under an employment contract dated January 2022, that is repayable through February 2025. Amounts repayable within one year are classified as accrued expenses and amounts repayable in more than one year are recognized as noncurrent liabilities. As of March 31, 2024, no amounts related to the January 2022 employment contract were included in noncurrent liabilities.

The Company’s Long Term Incentive Plan (the “Plan”) became effective on November 1, 2022. Pursuant to the Plan, 4,150,470 shares of Common Stock have been reserved for issuance under the Plan. Under the provisions of the Plan, the stock options shall be granted at an exercise price per share equal to at least the fair market value of the shares of common stock on the date of grant stock options and would generally have a term of 10 years. Stock options currently outstanding under the Plan generally vest on the second-year anniversary date of grant and exercisable at any time after the grant date.

The following table summarizes the stock option activity:

The Palo Alto Lease expires in April 2027 and has a five-year renewal option. Base rent for this lease is approximately $89,000 monthly with annual escalations of 3%. Pursuant to the terms of the lease, the Company received from the lessor approximately $300,000 for tenant improvements. The Company is required to repay this amount over the remaining term of the lease with 7% interest. The Company has applied the guidance in ASC 842 and has determined that this lease should be classified as an operating lease.

Debt

Related Party Loans

Founder Loans

In May 2021, the Company received proceeds from a loan in the amount of approximately $750,000 from its chairman and founding chief executive officer, Dr. Hoyoung Huh (“the Founder”).

The loan could be prepaid by the Company at any time prior to maturity with no prepayment penalties.

In August 2021, the Company received proceeds from the additional loan in the amount of approximately $750,000 from the Founder (together with the May 2021 loan, “Founder Loans”). The loan, which was scheduled to mature on July 31, 2022, bore interest at a rate of 1.0% per annum. The loan could be prepaid by the Company at any time prior to maturity with no prepayment penalties.

The Company made a $150,000 payment on the Founder Loans in December 2022. On April 28, 2023, the Company settled $448,940 of the principal and $26,830 of accrued interest through the issuance of the April 2023 Convertible Notes, related party (see below).

As security for payment of the Secured Note, the Security Agreement grants and assigns to the Founder the security interest in all of the assets of the Company and its subsidiaries.

The interest expense on the Secured Founder Loan totaled $20,959 and $0 for the three months ended March 31, 2024 and 2023, respectively.

Promissory Note

On November 1, 2022, the Company issued $1,512,500 in convertible notes (the “November 2022 Convertible Notes”). The convertible notes accrued interest at a rate of 8% per annum and had the maturity date of October 31, 2023, provided however that the Company agreed to make mandatory prepayments on this note (which were first be applied to accrued interest and then to principal) from time to time in amounts equal to 15% of the gross proceeds received by the Company from any equity lines, forward purchase agreements or other equity financings consummated by Company prior to the maturity date. The November 2022 Convertible Notes were convertible at the maturity date at the option of the holder in all or part of the principal and/or accrued interest into shares of common stock of the Company at a per share conversion price equal to 90% of the volume weighted

average price of a share of common stock of the Company for the five trading days immediately prior to the maturity date. The Company determined that the conversion upon maturity represented an embedded derivative that was subject to bifurcation and separate accounting with the change in the fair value recorded as other expense during each reporting period under the guidance in Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging (“ASC 815”) (the “November 2022 Convertible Note Liability”). The fair value of the November 2022 Convertible Note Liability at the issuance date was estimated at $165,000. The Company allocated the proceeds from the November 2022 Convertible Note first to the embedded derivative with the remaining proceeds allocated to the notes, which resulted in a discount on the convertible notes of $165,000 which was amortized to interest expense over the term of the convertible notes.

On November 1, 2023, the Company entered into an amendment to the November 2022 Convertible Notes whereby the principal amount of the notes was reduced from $1,512,500 to $650,000, the interest was reduced to 6% per annum, the maturity was extended to December 31, 2024 and the conversion terms were removed. Further, the amendment required the Company to make a payment of $300,000 by December 31, 2023, which was made in December 2023. The remaining balance of $378,622 including the accrued interest through the maturity date, is due on December 31, 2024. The amendment to the November 2022 Convertible Notes was accounted as an exchange into a promissory note (the “Promissory Note”) under the trouble debt restructuring (“TDR”) guidance in ASC Subtopic 470-60, Debt – Troubled Debt Restructurings by Debtors (“ASC 470-60”). Under the TDR guidance, the Company recognized a gain on debt extinguishment of $998,878 for the year ended December 31, 2023.

As of March 31, 2024 and December 31, 2023, the outstanding balance on the Promissory Note was $378,622, including principal of $350,000 and $28,622 in accrued interest.

The interest expense on November 2022 Convertible Note totaled $0 and $47,827, including amortization of the discount of $47,827, for the three months ended March 31, 2024 and 2023, respectively.

The April 2023 Convertible Notes bear interest at a rate of 6% per annum until their maturity date of October 28, 2023 and a default rate of 10% per annum thereafter. As at December 31, 2023 and March 31, 2024, the April 2023 Convertible Notes are in default. The April 2023 Convertible Notes are convertible at any time from the issuance date at the option of the holder into the Company’s common stock at $0.60 per share (the “April 2023 Conversion Feature”). The 2023 Convertible Note Warrants have the five year term and are exercisable at any time from the issuance date at the exercise price of $0.60 per share.

In connection with the issuance of the Convertible Notes and the Convertible Note Warrants, in consideration for its services in respect of the financing described above, the Company also issued to Paulson Investment Company, LLC (the “Placement Agent”) a warrant to purchase 209,670 shares of the Company’s common stock at a price per share of $0.60 (the “Placement Agent Warrant”). The Placement Agent Warrants have a five year term and are exercisable at any time from the issuance date. In addition, the Company paid the Placement Agent a commission of approximately $125,000.

The April 2023 Convertible Note Warrants and the Placement Agent Warrants were accounted as a liability under ASC 815, as the April 2023 Convertible Note Warrants and Placement Agent Warrants do not meet the criteria for equity classification due to the lack of available authorized shares. The aggregate fair value of the April 2023 Convertible Note Warrants and the Placement Agent Warrants was $1,527,640 and $87,552, respectively, at the issuance date using a Black Scholes Option Pricing Model. The initial fair value was determined based on the following assumptions:


Expected volatility	72.8	%
Risk-free interest rate	3.51	%
Expected term (in years)	5.0
Expected dividend yield	0	%

The Company determined that the April 2023 Conversion Feature is subject to bifurcation under the guidance in ASC 815 due to the lack of available authorized shares and registration requirements and recognized a derivative

liability of $560,436 at the issuance date (the “April 2023 Conversion Feature Liability”). The derivative liability was estimated using a Black Scholes Option Pricing Model, based on the following assumptions:


Expected volatility	66.5	%
Risk-free interest rate	4.94	%
Expected term (in years)	0.5
Expected dividend yield	0	%

At the issuance date, the proceeds from the April 2023 Convertible Notes were allocated to the April 2023 Convertible Note Warrants and the April 2023 Conversion Feature Liability based on their fair values of $1,527,640 and $560,436, respectively, with the remaining proceeds allocated to the convertible notes. The resulting discount on the April 2023 Convertible Notes was accreted into the interest expense over the term of the convertible notes using the effective interest method. The fair value of the Placement Agent Warrants at the issuance date and the cash commission were capitalized and amortized into the interest expense over the term of the convertible notes using the effective interest method. The Company is in default on the April 2023 Convertible Notes, however, the Company has not received demands for repayment through the filing date of these unaudited condensed consolidated financial statements.

In December 2023, certain holders of April 2023 Convertible Notes agreed to exchange the aggregate amount of $187,950 of April 2023 Convertible Notes, including the accrued interest, into the same amount of December 2023 Convertible Notes (see below).

In January 2024, additional holders of April 2023 Convertible Notes agreed to exchange the aggregate amount of $250,600 of April 2023 Convertible Notes, including the accrued interest, into the same amount of December 2023 Convertible Notes (see below).

The Company recorded interest expense of $44,376 and $0, including amortization of discount of $0 and $0, for the three months ended March 31, 2024 and 2023, respectively.

The amounts converted included $448,940 of principal and $26,830 accrued interest due under the 2021 Founder Loans, $400,000 of principal and $3,806 of interest due under the Venn Loan, and $250,000 of principal and $1,199 of accrued interest due under the March 2023 Founder Loan. The Company accounted for the issuance of the April 2023 convertible notes payable, related party, as a debt extinguishment in accordance with ASC 470 and recognized a loss of approximately $1,014,368 during the year ended December 31, 2023. As at December 31, 2023 and March 31, 2024, the April 2023 Convertible Note, related party was in default.

At the issuance date, the carrying value of the April 2023 Convertible Notes was reduced by the fair value of the related April 2023 Convertible Note Warrants and the April 2023 Conversion Feature Liability of $786,967 and $288,710, respectively, with the remaining proceeds allocated to the convertible notes. The April 2023 Conversion Feature Liability related to the April 2023 Convertible Notes, related party, was valued using a Black Scholes Option Pricing Model. The initial fair value was determined to be $0.3 million based on the following assumptions: stock price of $0.655, expected volatility of 66.5%, risk-free rate of 4.94% and expected term of 0.5 years. The resulting discount on the April 2023 Convertible Notes, related party was accreted into the interest expense over the term of the convertible notes using the effective interest method.

December 2023 Convertible Notes

In December, 2023, the Company issued convertible promissory notes in the aggregate principal amount of $1,000,000 (the “December 2023 Convertible Notes”). In addition, certain holders of April 2023 Convertible Notes agreed to exchange the aggregate amount of $187,950 of April 2023 Convertible Notes, including the accrued interest, into the same amount of December 2023 Convertible Notes.

In January and February 2024, the Company completed additional closes of the December 2023 Convertible Notes pursuant to which the Company issued the notes with the principal amount of $738,000. In addition, at those date, the holders of April 2023 Convertible Notes agreed to exchange the aggregate amount of $250,600 of April 2023 Convertible Notes, including the accrued interest, into the same amount of December 2023 Convertible Notes.

The December 2023 Convertible Notes bear an interest rate of 10% per annum and have a maturity date of December 18, 2024. The terms of the December 2023 Convertible Notes provide for automatic conversion of the outstanding principal amount of the December 2023 Convertible Notes and all accrued and unpaid interest upon a business combination (as defined in the agreement) into the Company common stock at the Conversion Price (the “Automatic Conversion Feature”). The Conversion Price is determined by reference to the purchase price payable in connection with such business combination, multiplied by 70%, where the price per share of the common stock is determined by reference to the 30-day volume weighted average price of the Company’s common stock on the public exchange immediately prior to conversion, resulting in 43% discount on the issuance price in the a business combination (the Automatic Discount”). If a business combination does not occur prior to the maturity date of the December 2023 Convertible Notes and if the Company’s Common Stock is listed on a public exchange as of such date, then the holders have the right, at their option, to convert the outstanding principal amount of the December 2023 Convertible Notes (and all accrued and unpaid interest thereof) into the shares of common stock of the Company at a price equal to the 30-day volume weighted average price of the Company’s common stock on the public exchange on which it is traded multiplied by 90% (the “Optional Conversion Feature”).

In consideration for its services in respect of the financing described above, the Company paid Paulson Investment Company, LLC (the “December 2023 Placement Agent”) the commission of $83,600 and $63,840 for the December 2023 issuances and the January and February 2024 issuances, respectively. Further, upon conversion of the December 2023 Convertible Notes into Common Stock of the Company, the December 2023 Placement Agent will receive shares of restricted common stock of the Company equal to (i) 4% of the total number of shares of common stock received upon conversion of the December 2023 Convertible Notes issued for new capital and (ii) 1% of the total number of shares of common stock received upon conversion of the December 2023 Convertible Notes issued for the exchange for April 2023 Convertible Notes. The cash commission to the December 2023 Placement Agent was capitalized and amortized into the interest expense over the term of the convertible notes using the effective interest method. The Company accounted for the issuance of the common stock shares to the Placement Agent under ASC 718 as equity-based compensation based on a performance condition. As the issuance of the common stock shares to the December 2023 Placement Agent upon conversion of the notes was deemed not probable both at issuance date and March 31, 2024, no expense was recorded for the three months ended March 31, 2024 related to this equity based compensation and had no impact on the interest expense for the three months ended March 31, 2024.

The Company determined that both the Automatic Conversion Feature and the Optional Conversion Feature are subject to bifurcation under the guidance in ASC 815 as variable-share redemption features at a discount. The Company recognized the total derivative liability of $573,546 and $0 for the Automatic Conversion Feature and the Optional Conversion Feature, respectively, at the issuance dates (together, the “December 2023 Conversion Feature Liability”). The fair value of the derivative liability related to the Automatic Conversion Feature was estimated by applying the probability of a business combination of 50% to the Automatic Discount of 43%. The fair value of the derivative liability related to the Optional Conversion Feature was immaterial as the probability that the Company is listed on a public exchange in absence of a business combination prior to the maturity of the December 2023 Convertible Notes was deemed minimal.

At the issuance date, the proceeds from the December 2023 Convertible Notes were allocated to the December 2023 Conversion Feature Liability based on its fair value with the remaining proceeds allocated to the convertible notes. The resulting discount on the and the December 2023 Convertible Notes was accreted into the interest expense over the term of the convertible notes using the effective interest method. The cash commission to the December 2023 Placement Agent was capitalized and amortized into the interest expense over the term of the convertible notes using the effective interest method.

The Company recorded interest expense of $186,775 for the three months ended March 31, 2024, including amortization of the discount on the convertible notes and the commission to the December 2023 Placement Agent of $134,590. At March 31, 2024, the outstanding principal balance of the December 2023 Convertible Notes was $1,704,603 plus accrued interest of $55,183.

Subject to the satisfaction of certain customary conditions including, without limitation, the effectiveness of a registration statement registering the shares issuable pursuant to the White Lion Purchase Agreement, the Company's right to sell shares to White Lion will commence on the effective date of the registration statement and extend until November 1, 2025. During such term, subject to the terms and conditions of the White Lion Purchase Agreement, the Company may notify White Lion when it exercises its right to sell shares (the effective date of such notice, a “Notice Date”).

The number of shares sold pursuant to any such notice may not exceed (i) the lower of (a) the Purchase Notice Fixed Limit (described below) and (b) the product of (1) the Average Daily Trading Volume (as defined in the White Lion Purchase Agreement), and (2) the applicable Percentage Limit (as defined in the White Lion Purchase Agreement). The Purchase Notice Fixed Limit is $500,000 upon payment of the Initial Commitment Shares (as defined in the White Lion Purchase Agreement) and can be increased in two tranches: (A) to $1,000,000 following an aggregate purchase of $5,000,000 shares and issuance by the Company to White Lion of an additional $250,000 in Commitment Shares, and (B) to $2,000,000 following an aggregate purchase of $10,000,000 shares and issuance by the for payment of an additional $250,000 in Commitment Shares (as defined in the White Lion Purchase Agreement).

The applicable Percentage Limit is 40% or 150% depending on the price the Company agrees to sell shares to White Lion. At an applicable Percentage Limit of 40%, the Purchase Price to be paid by White Lion for any such shares will equal 97% of lowest daily volume-weighted average price of Common Stock during a period of two consecutive Trading Days following the applicable Purchase Notice Date (as defined in the White Lion Purchase Agreement) until an aggregate of $50,000,000 in Purchase Notice Shares (as defined in the White Lion Purchase Agreement) have been purchased under White Lion Purchase Agreement, at which point the Purchase Price (as defined in the White Lion Purchase Agreement) to be paid by White Lion will equal 98% of the lowest daily volume-weighted average price of Common Stock during a period of two consecutive Trading Days following the applicable Purchase Notice Date. At an applicable Percentage Limit of 150%, the Purchase Price to be paid by White Lion for any such shares will equal 94.5% of the lowest daily volume-weighted average price of Common Stock during a period of three consecutive Trading Days following the applicable Purchase Notice Date.

The Company will have the right to terminate the White Lion Purchase Agreement at any time after commencement, at no cost or penalty, upon three (3) Trading Days’ prior written notice. Additionally, White Lion will have the right to terminate the White Lion Purchase Agreement upon three (3) days’ prior written notice to the Company if (i) there is a Fundamental Transaction (as defined in the White Lion Purchase Agreement), (ii) the Company is in breach or default in any material respect of the White Lion RRA, (iii) there is a lapse of the effectiveness, or unavailability of, the registration statement for a period of 45 consecutive Trading Days or for more than an aggregate of 90 Trading Days in any 365-day period, (iv) the suspension of trading of the Common Stock for a period of five (5) consecutive Trading Days, (v) the material breach of the White Lion Purchase Agreement by the Company, which breach is not cured within the applicable cure period or (vi) a Material Adverse Effect (as defined

in the White Lion Purchase Agreement) has occurred and is continuing. No termination of the White Lion Purchase Agreement will affect the registration rights provisions contained in the White Lion RRA.

In consideration for the commitments of White Lion, as described above, the Company has agreed that it will issue to White Lion shares of Common Stock having a value of $250,000 based upon the Closing Sale Price (as defined in the White Lion Purchase Agreement) of Common Stock two Trading Days prior to the filing of the Initial Registration Statement as Initial Commitment Shares. The Company may increase the number of shares it may sell to White Lion by issuing additional Commitment Shares in two additional tranches of $250,000 each. The Company issued Initial Commitment Shares of 50,200 shares of Common Stock to White Lion, based upon the Closing Sale Price of our Common Stock of $4.98 per share on November 30, 2022.

Concurrently with the execution of the White Lion Purchase Agreement, the Company entered into the White Lion RRA with White Lion in which the Company agreed to register the shares of Common Stock purchased by White Lion with the SEC for resale within 30 days of the consummation of a business combination. The White Lion RRA also contains usual and customary damages provisions for failure to file and failure to have the registration statement declared effective by the SEC within the time periods specified.

The White Lion Purchase Agreement and the White Lion RRA contain customary representations, warranties, conditions and indemnification obligations of the parties. The representations, warranties and covenants contained in such agreements were made only for purposes of such agreements and as of specific dates, were solely for the benefit of the parties to such agreements and may be subject to limitations agreed upon by the contracting parties.

The White Lion Purchase Agreement was accounted for as a standby equity purchase agreement under ASC 815 as it includes an embedded put option and an embedded forward option. The put option is recognized on inception and the forward option is recognized upon issuance of notice for the sale of the Company's Common Stock. The fair value of the derivative liability related to the embedded put option (“White Lion Derivative Liability) was estimated at $1,900,000 at the inception of the agreement. The fair value of the White Lion Derivative Liability was determined using a Monte Carlo simulation based on the projected stock price of $13.05, expected volatility of 86.5%, risk-free rate of 4.53% and discounted at 45.0% for the probability of the Company timely filing all SEC documents and meeting the NASDAQ listing requirements.

In March 2023, the Company entered into an amendment to the White Lion Purchase Agreement to give the Company the right, but not the obligation to require White Lion to purchase shares of the Company's common stock while trading on the OTC Market. Under the terms of the amendment, at an applicable Percentage Limit of 200%, the Purchase Price to be paid by White Lion for any such shares will equal 90% of the lowest daily volume-weighted average price of common stock during a period of six consecutive Trading Days following the applicable Purchase Notice Date if the Company is listed on the OTC Market with the exception of the OTC Pink or OTC Bulletin Board, in which case the Purchase Price will equal 85% of the lowest daily volume-weighted average price of common stock during a period of six consecutive Trading Days following the applicable Purchase Notice Date. Further, the Company will issue to White Lion within five (5) Trading Days following the effective date of the amendment fully paid, non-assessable shares of the Company's common stock equal to the quotient obtained by dividing (i) $250,000 and (ii) the lowest traded sale price of the common stock of the 10 (ten) Trading Days prior to the effective date of the amendment, minus 50,200. In March 2023, the Company issued 412,763 shares of its common stock to White Lion.

In August 2023, the Company and White Lion entered into a second amendment to the common stock Purchase Agreement (the “Second Amendment”). The Second Amendment includes, among other things, the right of the Company to issue a Purchase Notice (defined in the Second Amendment as an “Accelerated Purchase Notice”) requesting White Lion to purchase newly issued shares of common stock from the Company, subject to acceptance by White Lion, with pricing of the shares to be sold by the Company to White Lion under such Accelerated Purchase Notice determined on the date of issuance by the Company of the Accelerate Purchase Notice and acceptance by White Lion (the date of such notice defined as the “Accelerated Valuation Period”). Such accelerated purchases pursuant to an Accelerated Purchase Notice will be sold to White Lion at a price, defined as an “Accelerated Purchase Price,” equal to the lower of (i) the opening price of common stock during the Accelerated Valuation Period, (ii) the closing price of the common stock during Accelerated Valuation Period, or (iii) the volume weighted average price of the common stock during Accelerated Valuation Period; provided, however, that if at the time the Company delivers an Accelerated Purchase Notice to Investor the price of the common stock is lower than the opening price of the common stock during the Accelerated Valuation Period, the Accelerated Purchase Price will be discounted by 20%. In addition, the Second Amendment provides for an “Accelerated Purchase Notice Limit” equal to 200%.

In addition, in the event the Company does not issue Purchase Notices (as defined in the White Lion Purchase Agreement) to White Lion providing for the purchase of at least $1,250,000 of Purchase Shares (as defined in the White Lion Purchase Agreement and Second Amendment) in the aggregate within 180 days following the effective date of the amendment, the Company will issue to White Lion an additional number of fully paid, non-assessable shares of common stock equal to the quotient obtained by dividing (i) $150,000 and (ii) the lowest Closing Sale Price (as defined in the White Lion Purchase Agreement and Second Amendment) of common stock of the 10 (ten) Trading Days prior to the 180th day following the effective date of the amendment.

As at March 31, 2024 and December 31, 2023, the Company had no outstanding purchase notices issued to White Lion.

Public Warrants

In November 2022, upon consummation of the Business Combination, the Company assumed 2,875,000 public warrants from Ignyte Acquisition Corporation. Each whole warrant entitles the holder to purchase one share of Common Stock at a price of $11.50 per share, subject to adjustment as discussed herein. The warrants became exercisable 30 days after the completion of the Business Combination. However, no warrants will be exercisable for cash unless the Company has an effective and current registration statement covering the shares of common stock issuable upon exercise of the warrants and a current prospectus relating to such shares of common stock. Notwithstanding the foregoing, if a registration statement covering the shares of common stock issuable upon exercise of the public warrants is not effective within a specified period following the consummation of the initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to the exemption provided by Section 3(a)(9) of the Securities Act, provided that such exemption is available. If that exemption, or another exemption, is not available, holders will not be able to exercise their warrants on a cashless basis. In the event of such cashless exercise, each holder would pay the exercise price by surrendering the warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” for this purpose will mean the average reported last sale price of the shares of common stock for the 5 trading days ending on the trading day prior to the date of exercise. The warrants will expire on the fifth anniversary of the completion of an initial Business Combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

The Company may call the warrants for redemption:

•

in whole and not in part;

•

at a price of $0.01 per warrant;

•

at any time after the warrants become exercisable,

•

upon not less than 30 days’ prior written notice of redemption to each warrant holder; and

•

if, and only if, the reported last sale price of the Common Stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations) for any 20 trading days within a 30-trading day period commencing at any time after the warrants become exercisable and ending on the third business day prior to the notice of redemption to warrant holders; and

•

if, and only if, there is a current registration statement in effect with respect to the shares of common stock underlying such warrants.

If the Company calls the warrants for redemption as described above, the Company’s management will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” for this purpose shall mean the average

reported last sale price of the shares of common stock for the 5 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants.

There were no exercises or forfeitures of the Public Warrants during the three months ended March 31, 2024.

Private Placement Warrants

In November 2022, upon consummation of the Business Combination, the Company assumed 2,500,000 Private Placement Warrants from Ignyte Acquisition Corporation. Each Private Placement Warrant will entitle the holder to purchase one share of common stock at a price of $11.50 per share, subject to adjustment.

The Private Placement Warrants are identical to the Public Warrants, except that the Private Placement Warrants were non-redeemable and may be exercised on a cashless basis, in each case so long as they continue to be held by the initial purchasers or their permitted transferees.

The Private Placement Warrants were accounted for under ASC 815, pursuant to which the Private Placement Warrants do not meet the criteria for equity classification and must be recorded as liabilities. The Private Placement Warrants were valued using the Black Scholes Option Pricing Model, which is considered to be a Level 3 fair value measurement, as there was no observable market for the Private Placement Warrants and was determined based on significant inputs not observable in the market.

The following weighted average assumptions were used in determining the fair value of the Private Placement Warrants at March 31, 2024:


	March 31,
		2024
Expected volatility			100	%
Risk-free interest rate			4.40	%
Expected term (in years)			3.59
Expected dividend yield			0	%

There were no exercises or forfeitures of the Private Placement Warrants during the three months ended March 31, 2024.

Grant Revenue

Government grants

The Company has one active government grant with the Department of Defense, US Army Medical Research Acquisition Activity. This grant is for work on a COVID-19 therapeutic with a potential of $4.0 million, awarded in stages starting in January 2021 and with potential stages running through September 2026. Funding from the grant is received after expenditures have been incurred by the Company pursuant to the pre-approved statement of work and upon submission of a detailed voucher. The Grant is governed by the DoD Grant and Agreement Regulations, a subsection of the Code of Federal Regulations and requires the Company to provide financial and technical reports on a periodic basis to the Department of Defense.

For the three months ended March 31, 2024 and 2023, grant revenue of $0 and $13,854, respectively was recognized from this grant. Approximately $2.5 million in funding remains available for this grant at March 31, 2024

Income Taxes

The Company did not provide for any income taxes for the three months ended March 31, 2024 and 2023. The Company has evaluated the positive and negative evidence bearing upon its ability to realize the deferred tax assets. Management has considered the Company’s history of cumulative net losses incurred since inception and its lack of commercialization of any products or generation of any revenue from product sales since inception and has concluded that it is not more likely than not that the Company will realize the benefits of the deferred tax assets. Accordingly, a full valuation allowance has been established against the deferred tax assets as of March 31, 2024 and December 31, 2023. The Company recognized tax expense of $0 for the three months ended March 31, 2024 and 2023.

Overview

Peak Bio is a clinical-stage biopharmaceutical company focused on developing therapeutics addressing significant unmet need in the areas of oncology, inflammation and rare diseases. Our management team has a combined 50 years of industry experience in the areas of small molecules, antibodies, and antibody-drug-conjugates (ADC).

With our current strategic focus, we have leveraged two decades of industry learning in the antibody-drug-conjugate (ADC) field to develop a platform of proprietary technologies that enable us to design ADCs to have improved efficacy, safety, and tolerability relative to existing antibody or ADC therapies. Our most advanced platform, PH-1 or Thailanstatin is being used to generate a pipeline of proprietary ADC product candidates to address patient populations with improved efficacy relative to traditional ADC-based therapies. Our second product candidate is an ADC targeting Trop2, an antigen broadly expressed in solid tumors. We expect our Trop2 ADC to enter clinical development by late 2024. Our Trop2 ADC and other undisclosed discovery-stage product candidates are based on our proprietary PH-1 platform of toxin payloads targeting RNA splicing.

Despite commercial success of the ADCs currently on the market, there continues to be a need for ADCs that not only deliver antibody-directed payloads selectively to their tumors, but to also release them safely via improved linker technology and avoid off- target toxicities. Secondly, we believe that adding an immunomodulatory effect to our toxin(s) that engages our immune systems to assist in the cancer killing would contribute to improved tumor killing.

Our lead product candidate for which we are seeking a strategic partner for, PHP-303 is a small molecule, 5th generation Phase 2 clinical-ready neutrophil elastase (NE) inhibitor (NEI). We are planning a Phase 2 clinical study in Alpha-1 anti-trypsin deficiency (AATD) patients. We have completed two Phase 1 trials of PHP-303 in healthy volunteers testing higher doses of PHP-303 by single-ascending dose (SAD) and multiple-ascending dose (MAD). PHP-303 demonstrated dose- dependent pharmacokinetics and the recommended Phase 2 dose was achieved in these trials. A maximum tolerated dose for PHP-303 was not achieved in these Phase 1 trials.

We do not have any products available for commercial sale, and we have not generated any product revenue from our portfolio of product candidates. Our ability to generate revenue sufficient to achieve profitability, if ever, will depend on the successful development and eventual commercialization of our potential therapies, which we expect, if it ever occurs, will take a number of years. The research and development efforts require significant amounts of additional capital and adequate personnel infrastructure. There can be no assurance that our research and development activities will be successfully completed, or that our potential therapies will be commercially viable.

We have incurred significant losses since the commencement of our operations. Our net loss was $2.4 million for the three months ended March 31, 2024 and $12.8 million and $13.1 million for the years ended December 31, 2023 and 2022, respectively. Since the end of March 31, 2024, we raised $3.5 million from the issuance of May 2024 Convertible Notes. We expect to incur significant expenses and operating losses for the foreseeable future as we continue our efforts to identify product candidates and seek regulatory approvals within our portfolio.

We will need additional financing to fund our ongoing activities and to close the Merger with Akari (defined below). We may raise this additional funding through the sale of equity, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions and funding under government contracts.

We may be unable to raise additional funds or enter into other arrangements when needed on favorable terms, or at all. There can be no assurances that other sources of financing will be available. Due to these uncertainties, there is substantial doubt about our ability to continue as a going concern.

The accompanying unaudited condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The unaudited condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or classification of liabilities that might result from the outcome of the uncertainties discussed above.

Recent Developments

Akari Merger

On March 4, 2024, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Akari Therapeutics, Plc, a public company limited by shares incorporated in England and Wales (“Akari”), and Pegasus Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Akari (“Merger Sub”), pursuant to which, upon the terms and subject to the conditions thereof, Merger Sub will be merged with and into Peak Bio (the “Merger”), with Peak Bio surviving the Merger as a wholly-owned subsidiary of Akari.

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, at the effective time of the Merger (the “Effective Time”), each issued and outstanding share of Common Stock (other than (x) shares of Common Stock held by us as treasury stock, or shares of Common Stock owned by Akari, Merger Sub or any direct or indirect wholly-owned subsidiaries of Akari and (y) Dissenting Shares (as defined in the Merger Agreement)), will be converted into the right to receive Akari American Depositary Shares (“Akari ADSs”) representing a number of Akari ordinary shares, par value $0.0001 per share (the “Akari Ordinary Shares”), equal to an exchange ratio calculated in accordance with the Merger Agreement (the “Exchange Ratio”), each such share duly and validly issued against the deposit of the requisite number of Akari Ordinary Shares in accordance with the Deposit Agreement (as defined in the Merger Agreement). The Exchange Ratio will be calculated such that the total number of shares of Akari ADSs to be issued as merger consideration for the Peak Common Stock will be expected to be, upon issuance, approximately 50% of the outstanding shares of Akari ADSs (provided, certain adjustments to this ratio will be made in respect of the net cash, as determined in accordance with the Merger Agreement, of each of Peak Bio and Akari at the close of business one business day prior to the anticipated consummation of the Merger). The Merger Agreement provides that, under certain circumstances, additional Akari ADSs may be issued to the holders of shares of Peak Common Stock following the consummation of the Merger equal to an exchange ratio calculated in accordance with the Merger Agreement (the “Additional Exchange Ratio”).

At the Effective Time, each warrant to purchase capital stock of Peak Bio (“Peak Warrant”) outstanding immediately prior to the Effective Time will be converted into and exchangeable for warrants to purchase a number of Akari Ordinary Shares or Akari ADSs, as determined by Akari (each, an “Adjusted Warrant”), on substantially similar terms and subject to substantially similar conditions as were applicable to such Peak Warrant immediately prior to the Effective Time, except (i) for terms rendered inoperative by reason of the transactions contemplated by the Merger Agreement, (ii) as provided in the following sentence and (iii) such amendments to the terms of the Adjusted Warrants as are necessary to comply with applicable Law (as defined in the Merger Agreement). The number of Akari Ordinary Shares (or the number of Akari Ordinary Shares underlying Akari ADSs, as applicable) subject to each Adjusted Warrant will be equal to the number of shares of Peak Common Stock issuable upon exercise of such Peak Warrant immediately prior to the Effective Time multiplied by the Exchange Ratio, with any fractional Akari Ordinary Shares or Akari ADSs rounded down to the nearest whole Akari Ordinary Share or Akari ADS, as applicable, and the exercise price with respect to each Akari Ordinary Share (or each Akari Ordinary Share underlying Akari ADSs, as applicable) underlying such Adjusted Warrant will be equal to the exercise price of such Peak Warrant immediately prior to the Effective Time divided by the Exchange Ratio. The grant of the Adjusted Warrants will be effected as of the Effective Time, or as soon thereafter as is reasonably practicable, taking into account Parent’s administrative procedures. The Adjusted Warrants will be further adjusted, if applicable, to give effect to the impact of the Additional Exchange Ratio.

Each option to acquire shares of Peak Common Stock (“Peak Option”) that is outstanding and unexercised immediately prior to the Effective Time, whether or not vested, will be assumed and converted into an option to purchase a number of Akari ordinary shares or Akari ADSs, as determined by Akari (each, an “Adjusted Option”). The number of Akari Ordinary Shares (or the number of Akari Ordinary Shares underlying Akari ADSs, as applicable) subject to the Adjusted Option will be equal to the product of (i) the total number of shares of Peak Common Stock subject to such Peak Option immediately prior to the Effective Time multiplied by (ii) the Exchange Ratio, with any fractional Akari Ordinary Shares or Akari ADSs rounded down to the nearest whole Akari Ordinary Share or Akari ADS, as applicable, and the exercise price per share of each Adjusted Option will be equal to the exercise price of such Peak Option immediately prior to the Effective Time divided by the Exchange Ratio. The Adjusted Options will be further adjusted, if applicable, to give effect to the impact of the Additional Exchange Ratio.

Voting Agreements

Concurrently with the Merger Agreement, we and Akari entered into voting and support agreements (the “Voting Agreements”) with certain stockholders of Peak Bio (the “Peak Stockholders”) and certain shareholders of Akari (the “Akari Shareholders” and, together with the Peak Stockholders, the “Supporting Holders”). The Supporting Holders have agreed to, among other things, vote their shares in favor of the Merger Agreement and the Merger or the issuance of Akari Ordinary Shares in connection therewith, as applicable, in accordance with the recommendation of the respective boards of directors of Peak Bio and Akari.

Bylaws Amendment

In connection with the execution of the Merger Agreement, on March 3, 2024, our Board approved an amendment to our Amended and Restated Bylaws (the “Bylaws Amendment”), which became effective immediately. The Bylaws Amendment requires that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer, employee or stockholder (including a beneficial owner) of the Company to the Company or the Company’s stockholders, (iii) any action asserting a claim against any director, officer, employee or stockholder (including a beneficial owner) of the Company arising under any provision of the Delaware General Corporation Law (“DGCL”) or the bylaws or the certificate of incorporation of the Company, or (iv) any action asserting a claim governed by the internal affairs doctrine shall, to the fullest extent permitted by law, be the Court of Chancery of the State of Delaware (or if the Court of Chancery for the State of Delaware does not have jurisdiction, a state court located within the State of Delaware or, if no state court located within the State of Delaware has subject matter jurisdiction, the federal district court for the District of Delaware). In addition, the Bylaws Amendment provides that unless the Company consents in writing to the selection of an alternative forum, the federal district courts of the United States shall be the exclusive forum for the resolution of any claim or cause of action arising under the Securities Act of 1933, as amended.

Financing

Secured Promissory Note

In January 2024, we received proceeds from a Senior Secured Promissory Note (the “Secured Founder Loan”) in the amount of $750,000 from our founder and director, Dr. Huh. In accordance with the terms of the Secured Founder Loan, we, also entered into a Security Agreement with Dr. Hue (the “Security Agreement”). The Secured Note has a maturity date on January 23, 2025 and carries an interest rate of 15% per annum. As security for payment of the Secured Note, the Security Agreement grants and assigns to the Founder the security interest in all of the assets of the Company and its subsidiaries.

December 2023 Convertible Note

In December, 2023, we raised proceeds from the issuance of convertible promissory notes in the aggregate principal amount of $1,000,000 (the “December 2023 Convertible Notes”). In addition, certain holders of April 2023 Convertible Notes agreed to exchange the aggregate amount of $187,950 of April 2023 Convertible Notes, including the accrued interest, into the same amount of December 2023 Convertible Notes.

In January and February 2024, we completed additional closes of the December 2023 Convertible Notes pursuant to which the Company issued the notes with the principal amount of $738,000. In addition, at those date, the holders of April 2023 Convertible Notes agreed to exchange the aggregate amount of $250,600 of April 2023 Convertible Notes, including the accrued interest, into the same amount of December 2023 Convertible Notes.

In consideration for its services in respect of the financing described above, we paid the Placement Agent a commission of $187,811. Further, upon conversion of the December 2023 Convertible Notes into Common Stock of the Company, the Placement Agent will receive shares of restricted Common Stock of the Company equal to (i) 4% of the total number of shares of Common Stock received upon conversion of the December 2023 Convertible Notes issued for the aggregate principal of $2,238,000 new capital and (ii) 1% of the total number of shares of Common Stock received upon conversion of the December 2023 Convertible Notes issued for the aggregate principal of $438,550 in exchange of the April 2023 Convertible Notes.

In December 2023, we issued a $500,000 related party December 2023 Convertible Note to the Key Company Stockholder. This note has the same terms as the December 2023 Convertible Notes outlined above.

May 2024 Convertible Notes

The May 2024 Convertible Notes carry an interest rate of 10% per annum, have a maturity date of December 18, 2024. The terms of the May 2024 Convertible Notes provide for automatic conversion of the outstanding principal amount of the notes and all accrued and unpaid interest upon a business combination (as defined in the agreement) into the Company common stock at the Conversion Price. The Conversion Price is determined by reference to the purchase price payable in connection with such business combination, multiplied by 50%, where the price per share of the common stock is determined by reference to the 30-day volume weighted average price of our common stock on the public exchange immediately prior to conversion. In conjunction with the May 2024 Convertible Notes, we entered into the Security Agreement which grants and assigns the May 2024 convertible note holders a senior security interest in all of the assets of the Company and its subsidiaries.

White Lion Common Stock Purchase and Registration Rights Agreements

On November 3, 2022, we entered into a Common Stock Purchase Agreement (the “White Lion Purchase Agreement”) and Registration Rights (the “White Lion RRA”) with White Lion Capital, LLC, a Delaware limited liability company (“White Lion”). Pursuant to the White Lion Purchase Agreement, we have the right, but not the obligation, to require White Lion to purchase, from time to time, up to $100,000,000 in aggregate gross purchase price of newly issued shares of our Common Stock, subject to certain limitations and conditions set forth in the White Lion Purchase Agreement. Capitalized terms used but not otherwise defined in this section shall have the meanings given to such terms by the White Lion Purchase Agreement and the White Lion RRA.

We are obligated under the White Lion Purchase Agreement and the White Lion RRA to file a registration statement with the SEC to register the Common Stock under the Securities Act, for the resale by White Lion of shares of Common Stock that we may issue to White Lion under the White Lion Purchase Agreement.

Subject to the satisfaction of certain customary conditions including, without limitation, the effectiveness of a registration statement registering the shares issuable pursuant to the White Lion Purchase Agreement, our right to sell shares to White Lion will commence on the effective date of the registration statement and extend until November 1, 2025. During such term, subject to the terms and conditions of the White Lion Purchase Agreement, we may notify White Lion when we exercise our right to sell shares (the effective date of such notice, a “Notice Date”).

The number of shares sold pursuant to any such notice may not exceed (i) the lower of (a) the Purchase Notice Fixed Limit (described below) and (b) the product of (1) the Average Daily Trading Volume (as defined in the White Lion Purchase Agreement), and (2) the applicable Percentage Limit (as defined in the White Lion Purchase Agreement). The Purchase Notice Fixed Limit is $500,000 upon payment of the Initial Commitment Shares (as defined in the White Lion Purchase Agreement) and can be increased in two tranches: (A) to $1,000,000 following an aggregate purchase of $5,000,000 shares and issuance by us to White Lion of an additional $250,000 in Commitment Shares, and (B) to $2,000,000 following an aggregate purchase of $10,000,000 shares and issuance by the for payment of an additional $250,000 in Commitment Shares (as defined in the White Lion Purchase Agreement).

The applicable Percentage Limit is 40% or 150% depending on the price we agree to sell shares to White Lion. At an applicable Percentage Limit of 40%, the Purchase Price to be paid by White Lion for any such shares will equal 97% of lowest daily volume-weighted average price of Common Stock during a period of two consecutive Trading Days following the applicable Purchase Notice Date (as defined in the White Lion Purchase Agreement) until an aggregate of $50,000,000 in Purchase Notice Shares (as defined in the White Lion Purchase Agreement) have been purchased under White Lion Purchase Agreement, at which point the Purchase Price (as defined in the White Lion Purchase Agreement) to be paid by White Lion will equal 98% of the lowest daily volume-weighted average price of Common Stock during a period of two consecutive Trading Days following the applicable Purchase Notice Date. At an applicable Percentage Limit of 150%, the Purchase Price to be paid by White Lion for any such shares will equal 94.5% of the lowest daily volume-weighted average price of Common Stock during a period of three consecutive Trading Days following the applicable Purchase Notice Date.

We will have the right to terminate the White Lion Purchase Agreement at any time after commencement, at no cost or penalty, upon three (3) Trading Days’ prior written notice. Additionally, White Lion will have the right to terminate the White Lion Purchase Agreement upon three (3) days’ prior written notice to us if (i) there is a Fundamental Transaction (as defined in the White Lion Purchase Agreement), (ii) we are in breach or default in any material respect of the White Lion RRA, (iii) there is a lapse of the effectiveness, or unavailability of, the registration statement for a period of 45 consecutive Trading Days or for more than an aggregate of 90 Trading Days in any 365-day period, (iv) the suspension of trading of the Common Stock for a period of five (5) consecutive Trading Days, (v) the material breach of the White Lion Purchase Agreement by us, which breach is not cured within the applicable cure period or (vi) a Material Adverse Effect (as defined in the White Lion Purchase Agreement) has occurred and is continuing. No termination of the White Lion Purchase Agreement will affect the registration rights provisions contained in the White Lion RRA.

In consideration for the commitments of White Lion, as described above, we have agreed that it will issue to White Lion shares of Common Stock having a value of $250,000 based upon the Closing Sale Price (as defined in the White Lion Purchase Agreement) of Common Stock two Trading Days prior to the filing of the Initial Registration Statement as Initial Commitment Shares. We may increase the number of shares it may sell to White

Lion by issuing additional Commitment Shares in two additional tranches of $250,000 each. We issued Initial Commitment Shares of 50,200 shares of Common Stock to White Lion, based upon the Closing Sale Price of our Common Stock of $4.98 per share on November 30, 2022.

Concurrently with the execution of the White Lion Purchase Agreement, we entered into the White Lion RRA with White Lion in which we have agreed to register the shares of Common Stock purchased by White Lion with the SEC for resale within 30 days of the consummation of a business combination. The White Lion RRA also contains usual and customary damages provisions for failure to file and failure to have the registration statement declared effective by the SEC within the time periods specified.

In March 2023, we entered into an amendment to the White Lion Purchase Agreement to give us the right, but not the obligation to require White Lion to purchase shares of our common stock while trading on the OTC Market. Under the terms of the amendment, we will issue to White Lion within five (5) Trading Days following the effective date of the amendment fully paid, non-assessable shares of our Common Stock equal to the quotient obtained by dividing (i) $250,000 and (ii) the lowest traded sale price of the common stock of the 10 (ten) Trading Days prior to the effective date of the amendment, minus 50,200. In March 2023, as compensation for its commitment to enter into the amendment, we issued 412,763 shares of our common stock to White Lion.

In August 2023, we and White Lion entered into a second amendment to the Common Stock Purchase Agreement (the “Second Amendment”). The Second Amendment includes, among other things, the right of the Company to issue a Purchase Notice (defined in the Second Amendment as an “Accelerated Purchase Notice”) requesting White Lion to purchase newly issued shares of common stock from us, subject to acceptance by White Lion, with pricing of the shares to be sold by us to White Lion under such Accelerated Purchase Notice determined on the date of issuance by us of the Accelerate Purchase Notice and acceptance by White Lion (the date of such notice defined as the “Accelerated Valuation Period”). Such accelerated purchases pursuant to an Accelerated Purchase Notice will be sold to White Lion at a price, defined as an “Accelerated Purchase Price,” equal to the lower of (i) the opening price of common stock during the Accelerated Valuation Period, (ii) the closing price of the common stock during Accelerated Valuation Period, or (iii) the volume weighted average price of the common stock during Accelerated Valuation Period; provided, however, that if at the time we deliver an Accelerated Purchase Notice to Investor the price of the common stock is lower than the opening price of the common stock during the Accelerated Valuation Period, the Accelerated Purchase Price will be discounted by 20%. In addition, the Second Amendment provides for an “Accelerated Purchase Notice Limit” equal to 200%.

In addition, in the event we do not issue Purchase Notices (as defined in the White Lion Purchase Agreement) to White Lion providing for the purchase of at least $1,250,000 of Purchase Shares (as defined in the White Lion Purchase Agreement and Second Amendment) in the aggregate within 180 days following the effective date of the amendment, we will issue to White Lion an additional number of fully paid, non-assessable shares of common stock equal to the quotient obtained by dividing (i) $150,000 and (ii) the lowest Closing Sale Price (as defined in the White Lion Purchase Agreement and Second Amendment) of common stock of the 10 (ten) Trading Days prior to the 180th day following the effective date of the amendment.

In September 2023, we issued notices to purchase the total of 729,000 common shares to White Lion for the total proceeds of $105,317. We issued no notices to purchase securities during the three months ended March 31, 2024.

Components of Results of Operations

Our unaudited condensed consolidated financial statements for the three months ended March 31, 2024 include the accounts of Peak Bio Co., Ltd. and its subsidiary, Peak Bio CA., Inc. All intercompany balances and transactions have been eliminated in consolidation.

Revenue

Our revenue has historically been generated through grants from government organizations. We currently have no commercially approved products. Grant revenue is recognized during the period that the research and

development services occur, as qualifying expenses are incurred or conditions of the grants are met. Qualifying expenses are recognized when incurred as research and development expenses. Expenses for grants are tracked by using a project code specific to the grant, and the employees also track hours worked by using the project code.

Grant Revenue

Our grant revenues are derived from research programs with the Department of Defense, US Army Medical Research Acquisition Activity for work on a COVID-19 therapeutic.

Grants awarded to us for research and development by government entities are outside the scope of the contracts with customers and contributions guidance. This is because these granting entities are not considered to be customers and are not receiving reciprocal value for their grant support provided to us. These grants provide us with payments for certain types of expenditures in return for research and development activities over a contractually defined period.

We recognize grant revenue based on the reimbursable costs that are incurred during the period, up to pre-approved award limits. The expenses associated with these reimbursements are reflected as a component of research and development expense in our consolidated statements of operations and comprehensive loss.

Research and Development Expense

We expense research and development costs as incurred. Research and development expense consist primarily of costs related to personnel, including salaries and other personnel related expenses, contract manufacturing and supply, consulting fees, and the cost of facilities and support services used in drug development. Assets acquired that are used for research and development and have no future alternative use are expensed as in-process research and development.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and related benefits, including stock-based compensation, related to our executive, finance, business development, legal, human resources and support functions. Other general and administrative expenses include professional fees for auditing, tax, consulting and patent-related services, rent and utilities and insurance.

Revenue

Our revenue has historically been generated through grants from government organizations. The total revenue for government grants was $0 and $13,854 for the three months ended March 31, 2024 and 2023, respectively. We performed no work under the government grant with the Department of Defense, US Army Medical Research Acquisition Activity during the three months ended March 31, 2024.

Research and Development Expense

The following table summarizes our research and development expenses:


	Three Months Ended March 31,
	2024		2023
Third-party direct project expenses
PHP-303	$	10,884	$	21,611
PH-1 ADC Platform		18,904		58,272

Total other research and development costs		40,481		633,223
Total research and development expenses	$	70,269	$	713,106

Research and development expense decreased by $0.6 million during the three months ended March 31, 2024 compared to the three months ended March 31, 2023. The decrease was primarily due to the decrease in personnel costs of $0.3 million driven by a reduction of R&D headcount during 2023 and a decrease in facility related and other costs, following the abandonment of our premises in Palo Alto, California of $0.2 million.

General and Administrative Expense

General and administrative expense decreased by $0.9 million during the three months ended March 31, 2024 compared to the three months ended March 31, 2023. The decrease was primarily due to a decrease in personnel costs of $0.4 million driven by a reduction of general and administrative personnel during 2023, decrease in facility related expense $0.2 million, and a decrease in professional fees related to public filings of $0.1 million.

Impairment Loss on Operating Lease Right-of-Use Asset

We recognized an impairment loss on the operating lease right-of-use asset of $3.5 million due to the abandonment of the premises in Palo Alto, California for the three months ended March 31, 2023.

Other Income, Net

Other income, net decreased by $0.7 million during the three months ended March 31, 2024 compared to the three months ended March 31, 2023 primarily due to the increase in interest expense, partially offset by the other income of $0.2 million related to the settlement of liability with a related party. Also, during the three months ended March 31, 2023, we recognized the gain on the fair value adjustment to the warrant liability of $0.5 million, with no similar gain recognized during the three months ended March 31, 2024.

We recognized an additional $0.3 million in interest expense, including the amortization of related discounts, during the three months ended March 31, 2024 as compared to the prior period, related to the November 2022 Convertible Notes, April 2023 Convertible Notes and December 2023 Convertible Notes.

Liquidity and Capital Resources

Sources of Liquidity

Since our inception, we have not generated any revenue from product sales and have incurred significant operating losses and negative cash flows from our operations. Our net loss was $2.4 million for the three months ended March 31, 2024 and $12.8 million and $13.1 million for the years ended December 31, 2023 and 2022, respectively. At March 31, 2024 we had cash of $0.1 million.

Since the beginning of 2024, we raised aggregate gross proceeds of approximately $0.7 million from the issuance of December 2023 Convertible Notes, $0.75 million from the issuance of Secured Founder Loan and $3.5 million from the issuance of May 2024 Convertible Notes.

Funding Requirements

We expect to incur losses from operations for the foreseeable future primarily due to research and development expenses, including expenses related to conducting research activities, pre-clinical expenses and clinical trials. Our future capital requirements will depend on a number of factors, including:

•

the scope, progress, results and costs of our clinical trials, including but not limited to PHP-303 and our PH-1 ADC Platform;

•

the cost of manufacturing drug supply for our clinical and preclinical studies;

•

the future results of on-going preclinical research and subsequent clinical trials for treatments for oncology, genetic disease, liver disease, inflammation, and other pipeline candidates we may identify from time to time, including our ability to obtain regulatory approvals;

•

any changes in regulatory standards relating to the review of our product candidates; and our ability to timely obtain such required regulatory approvals;

•

the number and development requirements of other product candidates that we pursue;

•

the emergence of competing technologies and other adverse market developments;

•

our ability, and the ability of our third-party manufacturers, to manufacture or supply sufficient quantities of clinical products;

•

the costs of future commercialization activities, if any, including establishing sales, marketing, manufacturing and distribution capabilities, for any of our product candidates for which we receive marketing approval;

•

our ability to achieve the degree of market acceptance necessary for future commercial success of our product candidates for which we receive marketing approval, if any;

•

the costs of preparing, filing, and prosecuting patent applications and maintaining, enforcing, and defending intellectual property-related claims;

•

the impact of litigation that may be brought against us or of litigation that we may pursue against others;

•

the extent to which we acquire or invest in businesses, products, and technologies;

•

our ability to successfully integrate acquired products and technologies into our business, including the possibility that the expected benefits of the transactions will not be fully realized by us or may take longer to realize than expected;

•

our ability to establish and maintain collaborations, partnerships or other similar arrangements and to obtain or satisfy any milestone, royalty, or other payments from any such collaborations;

•

the extent to which our business could be adversely impacted by the effects of COVID-19 outbreak, including due to actions by us, governments, suppliers or other third parties to control the spread of COVID-19, or by other health epidemics or pandemics; and

•

the costs of operating as a public company.

We expect to incur significant expenses and operating losses for the foreseeable future as we continue our efforts to identify product candidates and seek regulatory approvals within our gene therapy portfolio.

Additional financing will be needed to fund our ongoing activities. We may raise this additional funding through the sale of equity, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions and funding under government contracts. We may be unable to raise additional funds or enter into such other arrangements or arrangement when needed on favorable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate certain of our research and development programs. There can be no assurances that other sources of financing would be available. Due to these uncertainties, there is substantial doubt about our ability to continue as a going concern.

Our future operations are highly dependent on a combination of factors, including (i) the timely and successful completion of additional financing; (ii) the success of our research and development programs; (iii) the development of competitive therapies by other biotechnology and pharmaceutical companies, (iv) our ability to attract and retain key employees, (v) our ability to manage growth of the organization; (vi) our ability to protect our proprietary technology; and ultimately (vii) regulatory approval and market acceptance of our product candidates.

Cash Flows Discussion

The following table summarizes our cash flows for the periods indicated:


	Three Months Ended March 31,
	2024			2023
Net cash used in operating activities	$	(1,417,672	)	$	(1,440,075	)
Net cash used in investing activities		—			—
Net cash provided by financing activities		1,108,163			1,144,429
Net (decrease) increase in cash, cash equivalents and restricted cash	$	(309,509	)	$	(295,646	)

Operating Activities

Net cash used in operating activities for the three months ended March 31, 2024 was the same as the net cash used for the three months ended March 31, 2023. Although the operating expenses decreased by $1.4 million in 2024 as compared to 2023, this decrease was offset by the increase in accounts payable and accruals due to the timing of the cash outlays. The decrease in the operating expenses is due to the reduction in facilities expenses, reduction in headcount of general and administrative employees, and decreases in direct project expenses related to the PHP-303 program, the PH-1 ADC Platform, and other general and pre-clinical programs as a result of delays in our ongoing and planned research activities .

Investing Activities

During the three months ended March 31, 2024 and 2023, there was no net cash used in investing activities.

During the three months ended March 31, 2024 net cash provided by financing activities was driven by the net proceeds from additional closes of the December 2023 Convertible Notes in the amount of $0.7 million and proceeds from a related party loan of $0.7 million, partially offset by repayment of the Insurance Financing Payable of $0.3 million.

During the three months ended March 31, 2023 net cash provided by financing activities was driven by the net proceeds from advances payable of $1.2 million and proceeds from a related party loan of $0.3 million, partially offset by repayment of the Insurance Financing Payable of $0.3 million.

Contractual Obligations and Commitments

In October 2021, we entered into a lease for laboratory and office facilities in Palo Alto, California that expires in March 2027 with a five-year renewal option and opened a secured letter of credit with a third-party financial institution in lieu of a security deposit for $177,000. Base rent for this sublease is approximately $89,000 monthly with annual escalations of 3%. In March 2023, we vacated the premises and returned possession of the premises to the landlord in April 2023. The full amount of the security deposit has been applied to back rent and we are still responsible for the outstanding payments under the lease. In June 2024, the landlord was awarded a default judgment against the Company in the amount of $796,773, primarily representing past due rent which is included in the operating lease liability. The Company is in the process of negotiating a settlement with the landlord.

debt for a one-time payment of $85,000, resulting in $207,967 recognized during three months ended March 31, 2024 in cancellation of trade liability, and terminated the administrative services and facilities agreement. The Company recognized $0 and $36,357 expenses under the administrative services and facilities agreement for the three months ended March 31, 2024 and 2023, respectively.

On April 1, 2024, the Company and pH Pharma Co., Ltd entered into an administrative services agreement whereby pH Pharma Co., Ltd will perform investor relations services, functions and responsibilities on behalf of the Company in the Republic of Korea. Under the agreement, the Company is obligated to pay pH Pharma Co., Ltd. a one-time fee of $230,000 for the services performed from January 1, 2024 through April 30, 2024 and a monthly fee of $10,000 per month for services rendered from May 1, 2024 through July 31, 2024. At March 31, 2024, the amounts accrued to pH Pharma Co., Ltd under this agreement totaled $230,000, included in accounts payable in the unaudited condensed consolidated balance sheets. The Company recognized $172,500 expense under this administrative services agreement for the three months ended March 31, 2024.

Critical Accounting Policies and Significant Judgments and Estimates

The preparation of our unaudited interim condensed consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America and our discussion and analysis of our financial condition and operating results require our management to make judgments, assumptions and estimates that affect the amounts reported. Actual results may differ from these estimates. The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period or in the period of the revision and future periods if the revision affects both current and future periods.

Our significant accounting policies and estimates are described in Note 2, “Summary of Significant Accounting Policies,” of the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 filed with the SEC on August 5, 2024, which describes the significant accounting policies and methods used in the preparation of our consolidated financial statements.

There have been no material changes to our critical accounting policies and estimates as from the date upon which we filed our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 with the SEC.

Recently Adopted Accounting Standards

On January 1, 2024, on adoption of ASU 2020-06, the Company determined that the April 2023 Conversion Feature Liability met the derivative accounting scope exception and the conversion feature no longer required bifurcation form the April 2023 Convertible Notes and April 2023 Convertible Notes, related party (see Note 10). On January 1, 2024, the fair value of the fair value of the April 2023 Conversion Feature Liability was zero. Therefore, the adoption had no impact on the Company’s unaudited condensed consolidated financial statements.

Recently Issued Accounting Standards Not Yet Adopted

There were no other recently issued but not yet effective accounting pronouncements that will have a material effect on the accompanying unaudited condensed consolidated financial statements.

JOBS Act Accounting Election

We qualify as an “emerging growth company” as defined in the JOBS Act. An emerging growth company may take advantage of reduced reporting requirements that are not otherwise applicable to public companies. These provisions include, but are not limited to:

•

being permitted to present only two years of audited financial statements and only two years of related Management’s Discussion and Analysis of Financial Condition and Results of Operations in this Form 10-Q;

•

not being required to comply with the auditor attestation requirements on the effectiveness of our internal controls over financial reporting;

•

not being required to comply with any requirement that may be adopted by the PCAOB regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis);

•

reduced disclosure obligations regarding executive compensation arrangements; and

•

exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

We may use these provisions until the last day of our fiscal year in which the fifth anniversary of the completion of this offering occurs. However, if certain events occur prior to the end of such five-year period, including if we become a “large accelerated filer,” our annual gross revenue exceeds $1.235 billion, or we issue more than $1.0 billion of non-convertible debt in any three-year period, we will cease to be an emerging growth company prior to the end of such five-year period.

We have elected to take advantage of certain of the reduced disclosure obligations in this Form 10-Q and may elect to take advantage of other reduced reporting requirements in future filings. As a result, the information that we provide to our shareholders may be different than the information you receive from other public companies in which you hold stock.

The JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards, until those standards apply to private companies. We have elected to take advantage of the benefits of this extended transition period and, therefore, we will not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. Our financial statements may therefore not be comparable to those of companies that comply with such new or revised accounting standards. Until the date that we are no longer an emerging growth company or affirmatively and irrevocably opt out of the exemption provided by Section 7(a)(2)(B) of the Securities Act upon issuance of a new or revised accounting standard that applies to our financial statements and that has a different effective date for public and private companies, we will disclose the date on which we will adopt the recently issued accounting standard.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Not applicable.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2024. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, mean controls and other procedures of a company that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Disclosure controls include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to management, including our principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2024, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were not effective as of the end of the period covered by this Quarterly Report on Form 10-Q due to material weaknesses in our internal control over financial reporting as describe below.

A material weakness is a control deficiency (within the meaning of the Public Company Accounting Oversight Board (United States) Auditing Standard No. 2201) or combination of control deficiencies that result in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. Management has identified the following material weaknesses:

•

Formal documentation of the Company’s internal control over financial reporting including risk assessments and processes needed to mitigate critical risks does not exist.

•

The Company lacks sufficient resources with respect to the number of people employed in its accounting department and the adequacy of their training in relation to its financial reporting requirements.

•

The Company’s internal control over financial reporting is ineffective with respect to its financial closing process in the following areas:

Preparation, review and approval of journal entries including the reasonableness of critical accounting estimates;

Completeness and proper cut-off of accrued liabilities;

Evaluation of third-party financial reporting advisors' capabilities and the monitoring and evaluation of the accuracy and completeness of their work product;

Timely closings as required to maintain compliance with reporting deadlines under applicable Securities and Exchange Commission regulations; and

Accuracy of diluted earnings per share calculation.

•

The Company experienced difficulties in applying complex accounting principles including:

Financial instruments accounted for under ASC 480 and ASC 815-10;

Differentiating between contractual liabilities and gain and loss contingencies; and

Fair value measurements.

Planned Remediation

Management continues to work to improve its controls related to our material weaknesses, specifically implementing improved processes and internal controls, and hiring outside consultants, to ensure the proper application of accounting practices and guidance. We also intend to increase our accounting staff as soon as economically feasible and sustainable to remediate these material weaknesses. These material weaknesses will not be considered to be remediated until the applicable remediated controls are operating for a sufficient period of time and management has concluded that these controls are operating effectively.

Changes in Internal Control

Except for the hiring of outside consultants as noted above, there has been no change in our internal control over financial reporting as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act during our most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

We are not currently a party to any material legal proceedings. At each reporting date, we evaluate whether a potential loss amount or a potential range of loss in respect of legal proceedings is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. We expense the costs related to our legal proceedings as incurred.

Item 1A. Risk Factors.

In addition to the other information set forth in this report, you should carefully consider the risk factors discussed in Part I, Item 1A. “Risk Factors” in our Annual report on Form 10-K for the fiscal year ended December 31, 2023, which could materially affect our business, financial condition, or results of operations. There have been no material changes in or additions to the risk factors referred to in the previous sentence.

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

None

Item 3. Defaults Upon Senior Securities.

The Company has evaluated the positive and negative evidence bearing upon its ability to realize the deferred tax assets. Management has considered the Company’s history of cumulative net losses incurred since inception and its lack of commercialization of any products or generation of any revenue from product sales since inception and has concluded that it is not more likely than not that the Company will realize the benefits of the deferred tax assets. Accordingly, a full valuation allowance has been established against the deferred tax assets as of March 31, 2024 and December 31, 2023. The Company recognized tax expense of $0 for the three months ended March 31, 2024 and 2023.
