Akari Therapeutics Plc

Notes to the Condensed Consolidated Financial Statements

(Unaudited)

Note 1. Description of Business

Business Overview

Akari Therapeutics, Plc, (the “Company” or “Akari”) is incorporated in the United Kingdom. The Company is a biotechnology company focused on developing advanced therapies for autoimmune and inflammatory diseases involving the complement component 5 (“C5”) and leukotriene B4 (“LTB4”) pathways. The Company’s activities since inception have consisted of performing research and development activities and raising capital.

The Company is subject to a number of risks similar to those of preclinical stage companies, including dependence on key individuals, uncertainty of product development and generation of revenues, dependence on outside sources of capital, risks associated with preclinical trials of products, dependence on third-party collaborators for research and development operations, need for marketing authorization of products, risks associated with protection of intellectual property, and competition with larger, better-capitalized companies.

To fully execute its business plan, the Company will need, among other things, to complete its research and development efforts and clinical and regulatory activities. These activities may take several years and will require significant operating and capital expenditures in the foreseeable future. There can be no assurance that these activities will be successful. If the Company is not successful in these activities it could delay, limit, reduce or terminate preclinical studies, clinical trials or other research and development activities.

Agreement and Plan of Merger

As further described in Note 3, in March 2024, the Company entered into an Agreement and Plan of Merger with Peak Bio, Inc. (“Peak Bio”). However, the Merger has not yet closed. The Company expects to close the merger in the fourth quarter of 2024.

Liquidity and Financial Condition

The Company follows the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 205-40, Presentation of Financial Statements—Going Concern, which requires management to assess the Company’s ability to continue as a going concern within one year after the date the consolidated financial statements are issued.

The Company has incurred substantial losses and negative cash flows since inception and had an accumulated deficit of$240.6 million as of June 30, 2024. The Company’s cash balance of$4.2 million as of June 30, 2024 is not sufficient to fund its operations for the one-year period after the date these condensed consolidated financial statements are issued. These factors raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The condensed consolidated financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

The Company anticipates incurring additional losses until such time, if ever, that it can generate significant sales of its product candidates currently in development. The Company is subject to a number of risks and uncertainties similar to those of other companies of the same size within the biotechnology industry, such as uncertainty of clinical trial outcomes, uncertainty of additional funding, and history of operating losses. Substantial additional financing will be needed by the Company to fund its operations and to commercially develop its product candidates. Management is currently evaluating different strategies to obtain the required funding for future operations. These strategies may include, but are not limited to: product development financing, private placements and/or public offerings of equity and/or debt securities, and strategic research and development collaborations and/or similar arrangements. There can be no assurance that these future funding efforts will be successful.

Nasdaq Continued Listing Rules

On April 5, 2024, the Company received a letter (“Letter”) from the Listing Qualifications Staff (the “Staff”) of The Nasdaq Capital Market (“Nasdaq”) notifying the Company that the Company’s shareholders’ equity as reported in its Form 10-K is no longer in compliance with the minimum shareholders’ equity requirement for continued listing on Nasdaq under Nasdaq Listing Rule 5550(b)(1), which requires listed companies to maintain shareholders’ equity of at least $2.5 million (the “Shareholders’ Equity Requirement”). As reported on the Form 10-K, the Company’s shareholders’ deficit as of December 31, 2023 was approximately $0.2 million. The Letter has no immediate impact on the listing of the Company’s American Depositary Shares (“ADSs”) on Nasdaq. As of June 30, 2024, the Company had a shareholders' deficit of$3.7 million and therefore is still not in compliance with the Shareholders' Equity Requirement.

In accordance with the Nasdaq Listing Rules, on May 20, 2024, the Company submitted a plan to regain compliance with the Stockholders’ Equity Requirement (the “Compliance Plan”) for the Staff’s consideration. On August 5, 2024, the Company was notified by the Staff that it has been granted an extension until September 30, 2024 to comply with the Compliance Plan and evidence compliance with the Minimum Equity Requirement.

There can be no assurance that the Company will be able to evidence compliance with the Shareholders’ Equity Requirement during the extension period granted by the Staff. In the event the Company does not satisfy the terms of the Nasdaq Notice and evidence compliance with the Shareholders’ Equity Requirement, the Staff will provide written notification that the Company’s securities will be delisted. The Company would, at that time, be entitled to request a hearing before a Nasdaq Hearings Panel to present its Compliance Plan to regain compliance and to request a further extension period to regain compliance with the Shareholders’ Equity Requirement. The request for a hearing would stay any delisting action by the Staff.

Note 2. Summary of Significant Accounting Policies

Basis of presentation – The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and the rules and regulations of the SEC and assumes that the Company will continue to operate as a going concern. Accordingly, they do not include all the information and footnotes required by U.S. GAAP for complete financial statements. These condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements and, in the opinion of management, reflect all adjustments, including normal and recurring adjustments, which the Company considers necessary for the fair statement of financial information. The results of operations and comprehensive loss for the three and six months ended June 30, 2024 are not necessarily indicative of expected results for the fiscal year ended December 31, 2024 or any other future period. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of December 31, 2023 and notes thereto included in its Form 10-K, as filed with the SEC on March 29, 2024.

Principles of consolidation – The condensed consolidated financial statements include the accounts of the Company, Celsus Therapeutics, Inc., a Delaware corporation, Volution Immuno Pharmaceuticals SA, a private Swiss company, and Akari Malta Limited, a private Maltese company, each wholly-owned subsidiaries. All intercompany transactions have been eliminated.

Foreign currency – The functional currency of the Company is U.S. dollars, as that is the currency of the primary economic environment in which the Company operates as well as the currency in which it has been financed.

Thereporting currency of the Company is U.S. dollars. The financial statements of certain of the Company's foreign subsidiaries are measured using their local currency as the functional currency. The Company translates its non-U.S. operations’ assets and liabilities denominated in foreign currencies into U.S. dollars at current rates of exchange as ofthe balance sheet date and income and expense items at the average exchange rate for the reporting period. Translation adjustments resulting from exchange rate fluctuations are recorded as foreign currency translation adjustments, a component of accumulated other comprehensive loss. Gains or losses from foreign currency transactions are included in foreign currency exchange gains/(losses).

Use of estimates – The preparation of the Company’s condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that may affect the reported amounts of assets, liabilities, expenses and related disclosures. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the valuation of share-based awards, the valuation of warrant liabilities, research and development prepayments, accruals and related expenses, and the valuation allowance for deferred income taxes. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Estimates are periodically reviewed considering changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results may differ from those estimates or assumptions.

Concentration of credit risk –Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash. The Company generally maintains balances in various operating accounts at financial institutions in amounts that may exceed federally insured limits. The Company has not experienced any losses related to its cash and does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.

Fair value measurements – Certain assets and liabilities are carried at fair value under U.S. GAAP. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, ASC 820, Fair Value Measurements and Disclosures (“ASC 820”) establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

•

Level 1 – quoted prices in active markets for identical assets and liabilities.

•

Level 2 – inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•

Level 3 – unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Determining which category an asset or liability falls within the hierarchy requires significant judgment. The Company evaluates its hierarchy disclosures each reporting period. The fair value hierarchy also requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The carrying values of the Company’s cash, prepaid expenses and other current assets, accounts payable and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities. The Company’s liability-classified warrants are recorded at their estimated fair value. See Note 4.

Cash – The Company considers all highly-liquid investments with original maturities of 90 days or less at the time of acquisition to be cash equivalents. The Company hadno cash equivalents as of June 30, 2024 or December 31, 2023.

Prepaid expenses –Payments made prior to the receipt of goods or services are capitalized until the goods or services are received.

Other current assets– Other current assets as of June 30, 2024 and December 31, 2023 were principally comprised of Value Added Tax (“VAT”) receivables.

Patent acquisition costs – Patent acquisition costs and related capitalized legal fees are amortized on a straight-line basis over the shorter of the legal or economic life. The estimated useful life is 22 years. The Company expenses costs associated with maintaining and defending patents after their issuance in the period incurred. Amortization expense for each of the three and six months ended June 30, 2024 and 2023 was less than $0.1 million.

Accrued expenses – As part of the process of preparing the condensed consolidated financial statements, the Company estimates accrued expenses. This process involves identifying services that third parties have performed on the Company’s behalf and estimating the level of service performed and the associated cost incurred on these services as of each balance sheet date in the Company’s condensed consolidated financial statements. Examples of estimated accrued expenses include contract service fees in conjunction with pre-clinical and clinical trials, professional service fees and contingent liabilities. In connection with these service fees, the Company’s estimates are most affected by its understanding of the status and timing of services provided relative to the actual services incurred by the service providers. If the Company does not identify certain costs that have been incurred or it under or over-estimates the level of services or costs of such services, the Company’s reported expenses for a reporting period could be understated or overstated. The date on which certain services commence, the level of services performed on or before a given date, and the cost of services are often subject to the Company’s estimation and judgment. The Company makes these judgments based upon the facts and circumstances known to it in accordance with U.S. GAAP. See Note 5.

Convertible Notes –On May 10, 2024, the Company entered into unsecured convertible promissory notes (the “May 2024 Notes”) with existing investors: the Company’s Chairman, Dr. Ray Prudo, and Interim President and Chief Executive Officer and director of the Company, Dr. Samir Patel, for an aggregate of $1.0 million in gross proceeds. The May 2024 Notes bear interest at 15% per annum, which may be increased to 17% upon the occurrence of certain events of default as described therein, and the principal and all accrued but unpaid interest is due on the date that is the earlier of (a) ten (10) business days following the Company’s receipt of a U.K. research and development tax credit from HM Revenue and Customs, and (b) November 10, 2024. Provided, however, at any time or times from the date of the note and until the tenth business day prior to closing of the Merger, the note holders are entitled to convert any portion of the outstanding and unpaid amount, including principal and accrued interest, into Company ADSs at a fixed conversion price equal to $1.59, representing the Nasdaq official closing price of the Company’s ADSs on the issuance date, subject to certain restrictions.

The Company accounts for convertible promissory notes in accordance with ASC Topic 470-20, Debt with Conversion and Other Options(“ASC 470-20”) and has not elected the fair value option as provided for within ASC Topics 815 and 825. Accordingly, the Company evaluated the embedded conversion and other features within the May 2024 Notes to determine whether any of the embedded features should be bifurcated from the host instrument and accounted for as a derivative at fair value. Based on management’s evaluation, the Company determined that the May 2024 Notes were not issued at a substantial premium and none of the embedded features were required to be bifurcated and accounted for separately. Accordingly, the May 2024 Notes are accounted for as a single liability measured at its amortized cost. Issuance costs incurred in connection with the issuance of the May 2024 Notes were immaterial. Interest expense incurred on the May 2024 Notes was less than $0.1 million for the three and six months ended June 30, 2024. As of June 30, 2024, accrued interest on the May 2024 Notes of less than $0.1 million is included within “Accrued expenses” in the Company’s balance sheets.

Warrant Liability – The Company accounts for ordinary share or ADS warrants as either equity instruments, liabilities or derivative liabilities in accordance with ASC Topic 480, Distinguishing Liabilities from Equity (“ASC 480”) and/or ASC Topic 815, Derivatives and Hedging (“ASC 815”), depending on the specific terms of the warrant agreement. Liability-classified warrants are recorded at their estimated fair values at issuance are remeasured each reporting period until they are exercised, terminated, reclassified or otherwise settled. Changes in the estimated fair value of liability-classified warrants are recorded in "change in fair value of warrant liability" in the Company’s condensed consolidated statements of operations and comprehensive loss. Equity-classified warrants are recorded within "additional paid-in capital" in the Company's condensed consolidated statements of shareholders' (deficit) equity at the time of issuance and not subject to remeasurement.

In connection with the sale of the ADSs in the September 2022 Registered Direct Offering, the Company issued to the investors registered Series A warrants (“Series A Warrants”) to purchase an aggregate of 755,000 ADSs at $17.00 per ADS and registered Series B warrants (“Series B Warrants”) to purchase an aggregate of 755,000 ADSs at $17.00 per ADS (collectively, the “September 2022 Warrants”).The Company determined that the September 2022 Warrants are not indexed to the Company’s own stock in the manner contemplated by ASC 815-40-15, Determining Whether an Instrument (or Embedded Feature) Is Indexed to an Entity’s Own Stock. Accordingly, the Company classifies the September 2022 Warrants as derivative liabilities in its consolidated balance sheets.

Other Current Liabilities – In February 2024, the Company entered into a short-term financing arrangement with a third-party vendor to finance insurance premiums. The aggregate amount financed under this agreement was $1.1 million bearing interest at an annual rate of 7.49%. As of June 30, 2024, the balance of $0.6 million, which is included in “Other current liabilities” in the Company’s balance sheets, is scheduled to be paid inmonthly installments through November 2024.

Research and development expenses – Costs associated with research and development are expensed as incurred unless there is an alternative future use in other research and development projects. Research and development expenses include, among other costs, salaries and personnel–related expenses, fees paid for contract research services, fees paid to clinical research organizations, costs incurred by outside laboratories, manufacturers and other accredited facilities in connection with clinical trials and preclinical studies.

Payments made prior to the receipt of goods or services to be used in research and development are capitalized until the goods or services are received. The Company records expenses related to clinical studies and manufacturing development activities based on its estimates of the services received and efforts expended pursuant to contracts with multiple contract research organizations and manufacturing vendors that conduct and manage these activities on its behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract, and may result in uneven cash flows. There may be instances in which payments made to the Company’s vendors will exceed the level of services provided and result in a prepayment of the expense. Payments under some of these contracts depend on factors such as the successful enrollment of subjects and the completion of clinical study milestones. In amortizing or accruing service fees, the Company estimates the time period over which services will be performed, enrollment of subjects, number of sites activated and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from the Company’s estimate, the Company will adjust the accrued or prepaid expense balance accordingly.

The Company accounts for research and development tax credits at the time its realization becomes probable as a credit to research and development expenses in the condensed consolidated statements of operations and comprehensive loss.

Merger-Related Costs– Merger-related costs include direct expenses incurred in connection with the proposed Merger, as more fully described in Note 3, and are comprised primarily of legal and professional fees and other incremental costs directly associated to the Merger. For the three and six months ended June 30, 2024 merger-related costs totaled$0.3 million and$1.3 million, respectively.

Restructuring and Other Costs– In May 2024, the Company began to implement a reduction-in-force of approximately 67% of its total workforce as a result of the recently announced program prioritization under which the Company’s HSCT-TMA program was suspended. The reduction-in-force was part of an operational restructuring plan (the “May 2024 Plan”) which included the elimination of certain senior management positions and was substantially completed by June 30, 2024. The purpose of the restructuring plan, including the reduction-in-force, is to reduce HSCT-TMA related operating costs, while supporting the execution of the Company’s long-term strategic plan. During the three and six months ended June 30, 2024, the Company has incurred restructuring-related charges of$1.6 million related to the May 2024 Plan, including $1.3 million related to severance and other settlement payments to terminated executives and employees, and $0.3 million of non-cash expenses related to accelerated vesting of equity awards. The Company doesnot expect to incur additional restructuring-related expenses related to the May 2024 Plan.

As of June 30, 2024, of the$1.6 million total restructuring-related charges incurred, $0.5 million wasunpaid and included in accrued expenses in the accompanying condensed consolidated balance sheet. See Note 5. The Company expects these costs to be payable through the fourth quarter of 2024.

Share-based compensation expense – The Company measures all share-based awards granted to employees, directors and non-employees based on the estimated fair value on the date of grant and recognizes compensation expense of those awards over the requisite service period, which is generally the vesting period of the respective awards. Forfeitures are accounted for as they occur. The Company classifies share-based compensation expense in its condensed consolidated statements of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.

The fair value of each restricted ordinary share award is determined on the date of grant based on the fair value of the Company’s ordinary shares on that same date. The fair value of each share option grant is determined on the date of grant using the Black-Scholes option pricing model, which requires inputs based on certain assumptions, including the expected stock price volatility, the expected term of the award, the risk-free interest rate, and expected dividends. See Note 7. The Company estimates stock price volatility based on the Company’s historical stock price performance over a period of time that matches the expected term of the stock options. The expected term of the Company’s options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield is based on the fact that the Company has never paid cash dividends on ordinary shares and does not expect to pay any cash dividends in the foreseeable future.

Leases – The Company accounts for its leases in accordance with ASC 842, Leases. In accordance with ASC 842, the Company records a right-of-use (“ROU”) asset and corresponding lease liability on the balance sheet for all leases with terms longer than 12 months. Leases with an initial term of twelve months or less are not recorded on the condensed consolidated balance sheet and are recognized on a straight-line basis over the lease term. As of June 30, 2024 and December 31, 2023, the Company did not have any leases with a term longer than twelve months. Accordingly, no ROU assets and corresponding lease liabilities are included in the Company’s condensed consolidated balance sheets as of June 30, 2024 or December 31, 2023.

Income taxes – In accordance with ASC 270, Interim Reporting, and ASC 740, Income Taxes, the Company is required at the end of each interim period to determine the best estimate of its annual effective tax rate and then apply that rate in providing for income taxes on a current year-to-date (interim period) basis. For the three and six months ended June 30, 2024 and 2023, the Company recorded no tax expense or benefit due to the expected current year loss and its historical losses. The Company has not recorded its net deferred tax asset as of either June 30, 2024 or December 31, 2023 because it maintained a full valuation allowance against all deferred tax assets as of these dates as management has determined that it is not more likely than not that the Company will realize these future tax benefits. As of June 30, 2024 and December 31, 2023, the Company had no uncertain tax positions.

Net loss per share– Basic net loss per ordinary share is computed by dividing net loss available to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period, which includes ordinary shares underlying pre-funded warrants, as such warrant is exercisable, in whole or in part, for nominal cash consideration with no expiration date. Diluted net loss per ordinary share includes the effect, if any, from the potential exercise or conversion of securities, such as stock options, unvested restricted stock units, and warrants, which would result in the issuance of incremental ordinary shares, unless their effect would be anti-dilutive. For each of the three and six months ended June 30, 2024 and 2023, diluted net loss per ordinary share is the same as basic net loss per ordinary share as the effects of the Company’s potentially dilutive securities were anti-dilutive.

The following potential dilutive securities, presented based on amounts outstanding at the end of each reporting period, have been excluded from the calculation of diluted net loss per share because including them would have had an anti-dilutive impact:

New Accounting Pronouncements– From time to time, new accounting pronouncements are issued by the FASB and rules are issued by the SEC that the Company has or will adopt as of a specified date. Unless otherwise noted, management does not believe that any other recently issued accounting pronouncements issued by the FASB or guidance issued by the SEC had, or is expected to have, a material impact on the Company’s present or future consolidated financial statements.

Recently Issued (Not Yet Adopted) Accounting Pronouncements

In November 2023, the FASB issued Accounting Standards Update (“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 is currently assessing the impact of this guidance on its consolidated financial statements and related disclosures.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures. This ASU improves the transparency of income tax disclosure by requiring consistent categories and greater disaggregation of information in the rate reconciliation, and income taxes paid disaggregated by jurisdiction. This guidance is effective for the Company for the year beginning January 1, 2025, with early adoption permitted. The amendments should be applied on a prospective basis, with retrospective application permitted. The Company is currently assessing the impact of this guidance on its consolidated financial statements and related disclosures.

Note 3. Agreement and Plan of Merger

Agreement and Plan of Merger

On March 4, 2024, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Peak Bio and Pegasus Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Akari (“Pegasus Merger Sub”), pursuant to which, upon the terms and subject to the conditions thereof, Pegasus 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 Peak Bio common stock, par value $0.0001 per share (the “Peak Common Stock”) (other than (x) shares of Peak Common Stock held by Peak Bio as treasury stock, or shares of Peak Common Stock owned by Akari, Pegasus 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 the Company’s ADSs representing a number of Akari ordinary shares, par value $0.0001 pershare (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 Akari and Peak Bio 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”).

The board of directors of each of Akari and Peak has unanimously approved the Merger Agreement and the transactions contemplated thereby. Consummation of the Merger is subject to various conditions, including, among others, (i) approval of the Merger Agreement and Merger by Peak Bio stockholders, (ii) Akari’s shareholders authorizing Akari’s board of directors to allot all Akari ordinary shares to be issued in connection with the Merger (to be represented by Akari ADSs), (iii) the absence of any law or order prohibiting consummation of the Merger, (iv) Akari’s Registration Statement on Form S-4 (to be issued in connection with the Merger) having been declared effective, (v) the Akari ADSs issuable to Peak Bio stockholders having been authorized for listing on Nasdaq, (vi) accuracy of the other party’s representations and warranties (subject to certain materiality standards set forth in the Merger Agreement), (vii) compliance by the other party in all material respects with such other party’s obligations under the Merger Agreement; (viii) the absence of a material adverse effect on the other party, (ix) the other party’s net cash being greater than negative $13.5 million and (x) the PIPE Investment (as defined in the Merger Agreement) shall have been consummated simultaneously with, and conditioned only upon, the occurrence of the closing, and shall result in net proceeds to Akari of at least $10 million.

Either Akari or Peak Bio may terminate the Merger Agreement under certain circumstances, including if (i) the Merger is not completed by December 2, 2024, (ii) the other party's board of directors withdraws, modifies or qualifies its recommendation in favor of the transactions contemplated by the Merger Agreement or approves or recommends an alternative transaction or (iii) Akari’s or Peak Bio’s board of directors, as applicable, resolves to enter into a definitive agreement with respect to a superior proposal prior to obtaining approval of the Akari ADS issuance or Merger, as applicable, from Akari’s shareholders or Peak Bio’s stockholders, as applicable. The Merger Agreement also provides that under certain specified circumstances of termination described in the Merger Agreement, Akari or Peak Bio, as applicable, will be required to pay a termination fee equal to $300,000 and reimburse the other party for expenses related to the transaction up to $1.5 million.

Concurrently with the Merger Agreement, Akari and Peak Bio entered into voting and support agreements (the “Voting Agreements”) with certain shareholders of Akari (the “Akari Shareholders”), and certain stockholders of Peak Bio (the “Peak Stockholders” and, together with the Akari Shareholders, 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 Akari and Peak Bio.

The Voting Agreements will terminate at the earliest to occur of (a) the Effective Time, (b) receipt of approval of the Supporting Holders, as applicable, and (c) such date and time as the Merger Agreement is validly terminated.

Note 4. Fair Value Measurements

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following table presents information about the Company’s financial liabilities measured at fair value on a recurring basis and indicates the level of the fair value hierarchy used to determine such values:

The Company’s Level 3 liabilities consist of the September 2022 Warrants, which were determined to be liability-classified instruments. There were no transfers between Level 1, Level 2, and Level 3 during the six months ended June 30, 2024 and 2023.

Changes in Level 3 Liabilities Measured at Fair Value on a Recurring Basis

The following table summarizes the activity in the warrant liability measured at fair value on a recurring basis using unobservable inputs (Level 3) during the six months ended June 30, 2024:

Assumptions Used in Determining Fair Value of Liability-Classified Warrants

The fair value of the warrant liability is based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The fair value of both the Series A Warrants and the Series B Warrants (each defined below) was determined using the Black-Scholes Option Pricing Model, which uses various assumptions, including (i) fair value of the Company’s ADSs, (ii) exercise price of the warrant, (iii) expected term of the warrant, (iv) expected volatility and (v) expected risk-free interest rate.

Below are the assumptions used for the fair value calculations of the Series A Warrants and Series B Warrants (each defined below), as of June 30, 2024 and December 31, 2023:

Note 5. Accrued Expenses

Accrued expenses consisted of the following as of June 30, 2024 and December 31, 2023:

Accrued restructuring expenses of $0.5 million as of June 30, 2024 relate to one-time termination benefits payable to former employees, including an executive, which are payable through the fourth quarter of 2024. See Note 2.

Note 6. Shareholders’ (Deficit) Equity

Ordinary Shares

On June 30, 2023, the Company’s shareholders approved an increase to the number of authorized ordinary shares, par value $0.0001 (the “Ordinary Shares”), the Company can issue by 35,000,000,000 ordinary shares in addition to the number of shares outstanding on June 30, 2023. Accordingly, as of June 30, 2024 and December 31, 2023, the Company was authorized to issue up to 45,122,321,523 ordinary shares.

2023 Equity Incentive Plan

On June 30, 2023, the Company’s shareholders approved the 2023 Equity Incentive Plan (the “2023 Plan”), which provides for the grant of stock options, both incentive stock options and nonqualified stock options, stock, with and without vesting restrictions, restricted stock units (“RSUs”) and stock appreciation rights, to be granted to employees, directors and consultants. The Company is permitted to issue up to 980,000,000 ordinary shares under the 2023 Plan, plus such additional number of ordinary shares (up to 855,637,300 ordinary shares) subject to awards granted under the 2014 Equity Incentive Plan (the “2014 Plan”), to the extent such awards are forfeited, cancelled, or expire unexercised.

As of June 30, 2024, the Company had 318,823,915 ordinary shares underlying outstanding equity awards under the 2023 Plan, consisting of stock options and RSUs, and 724,581,522 ordinary shares remained available for future grants under the 2023 Plan.

The 2023 and 2014 Plans provide that they be administered by the compensation committee of the board of directors. The exercise price for stock option awards may not be less than 100% of the fair market value of the Company’s ordinary shares on the date of grant and the term of awards may not be greater thanten years. The Company determines the fair value of its ordinary shares based on the quoted market price of its ADSs. Vesting periods are determined at the discretion of the compensation committee. Awards granted to employees typically vest overtwo tofour years and directors overone year.

2014 Equity Incentive Plan

Under the 2014 Plan the Company was authorized to grant stock options, RSUs and other awards, to employees, members of the board of directors and consultants. Upon effectiveness of the 2023 Plan no further awards were available to be issued under the 2014 Plan. As of June 30, 2024, the Company had 284,934,688 ordinary shares underlying outstanding equity awards under the 2014 Plan, consisting of stock options.

Stock Options

The following is a summary of the Company’s stock option activity under the 2014 Plan and the 2023 Plan for the six months ended June 30, 2024:

(1)

Includes both vested stock options as well as unvested stock options for which the requisite service period has not been rendered but that are expected to vest based on achievement of a service condition.

The aggregate intrinsic value of options is calculated as the difference between the exercise price of the options and the fair value of the Company’s ordinary shares for those options that had exercise prices lower than the fair value of the Company’s ordinary shares.

The weighted-average grant-date fair value per share of options granted during each of the six months ended June 30, 2024 and 2023 was less than $0.01.

Option Valuation

The weighted-average assumptions that the Company used to determine the fair value of share options granted were as follows, presented on a weighted average basis:

Restricted Stock Units

The 2014 Plan provided, and the 2023 Plan provides, for the award of RSUs. RSUs are granted to employees that are subject to time-based vesting conditions that lapse betweenone year and four years from date of grant, assuming continued employment. Compensation cost for time-based RSUs, which vest only on continued service, is recognized on a straight-line basis over the requisite service period based on the grant date fair of the RSUs, which is derived from the closing price of the Company’s ADSs on the date of grant.

The following table summarizes the Company’s RSU activity for the six months ended June 30, 2024:

The fair value of time-based RSUs that vested during the six months ended June 30, 2024 and 2023 was approximately $0.5 million and $0.1 million, respectively.

As of June 30, 2024,290,937,175 ordinary shares underlying vested time-based RSUs, which have been included in the condensed consolidated statement of shareholders’ (deficit) equity, were pending issuance.

Share-Based Compensation Expense

The Company classifies share-based compensation expense in the statement of operations in the same manner in which the award recipients’ payroll costs are classified or in which the award recipients’ service payments are classified. Total share-based compensation expense attributable to share-based payments made to employees, consultants and directors included in operating expenses in the Company's condensed consolidated statements of operations and comprehensive loss for the three and six months ended June 30, 2024 and 2023, was as follows:

During the three and six months ended June 30, 2024,276,000,000 ordinary shares underlying unvested time-based RSUs held by a former executive upon termination of employment were accelerated, resulting in additional stock-based compensation expense of $0.3 million.

As of June 30, 2024, total unrecognized compensation cost related to unvested stock options and time-based RSUs was $0.2 million and $0.2 million, respectively. The Company expects total unrecognized compensation costs related to unvested stock options and RSUs to be recognized over a weighted average period of 1.8 and 1.7 years, respectively.
