NOTES TO CONDENSED CONSOLIDATED STATEMENTS

1. Organization and Description of Business

Northwest Biotherapeutics, Inc. and its wholly owned subsidiaries Flaskworks, Northwest Biotherapeutics Limited (formerly known as Aracaris Ltd), Aracaris Capital, Ltd, Northwest Biotherapeutics B.V., and NW Bio GmbH (collectively, the “Company”, “we”, “us” and “our”) were organized to discover and develop innovative immunotherapies for cancer. The Company has developed DCVax® platform technologies for both operable and inoperable solid tumor cancers. The Company has wholly owned subsidiaries in Boston, the U.K., the Netherlands and Germany. On August 28, 2020, the Company acquired Flaskworks, LLC (“Flaskworks”), a company that has developed a system designed to close and automate the manufacturing of cell therapy products such as DCVax®. On July 24, 2023, the Company’s wholly-owned subsidiary changed its name from Aracaris Ltd to Northwest Biotherapeutics Limited.

The Company relies upon contract manufacturers for production of its DCVax products, research and development services, distribution and logistics, and related services, in compliance with the Company’s specifications and the applicable regulatory requirements.

The Company has completed a Phase 3 clinical trial of its DCVax®-L product for glioblastoma brain cancer, has publicly reported the results in a peer reviewed publication in a medical journal as well as at a medical conference, and ~~is working on final preparations for filing an application~~submitted a Marketing Authorization Application (MAA) for regulatory approval ofin the ~~product.~~U.K. in December 2023.

2. Financial Condition, Going Concern and Management Plans

The Company has incurred annual net operating losses since its inception. The Company had a net loss of ~~$45.1~~$18.3 million for the ~~nine~~three months ended ~~September 30, 2023.~~March 31, 2024. The Company used approximately ~~$36.7~~$12.4 million of cash in its operating activities during the ~~nine~~three months ended ~~September 30, 2023.~~March 31, 2024.

The Company does not expect to generate material revenue in the near future from the sale of products and is subject to all of the risks and uncertainties that are typically faced by biotechnology companies that devote substantially all of their efforts to research and development (“R&D”) and clinical trials and do not yet have commercial products. The Company expects to continue incurring annual losses for the foreseeable future. The Company’s existing liquidity is not sufficient to fund its operations, anticipated capital expenditures, working capital and other financing requirements until the Company reaches significant revenues. Until that time, the Company will need to obtain additional equity and/or debt financing, especially if the Company experiences downturns in its business that are more severe or longer than anticipated, or if the Company experiences significant increases in expense levels resulting from being a publicly-traded company or from expansion of operations. If the Company attempts to obtain additional equity or debt financing, the Company cannot assume that such financing will be available to the Company on favorable terms, or at all.

Because of recurring operating losses and operating cash flow deficits, there is substantial doubt about the Company’s ability to continue as a going concern for at least one year from the date of this filing. The consolidated financial statements have been prepared assuming that the Company will continue as a going concern, however, they do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets, or the amounts and classification of liabilities that may result from the outcome of this uncertainty.

3. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated interim financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated. Certain immaterial reclassifications have been made to prior period amounts to conform to the current period presentation.

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with the accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities and Exchange Commission (“SEC”) and on the same basis as the Company uses to prepare its annual audited consolidated financial statements. The condensed consolidated balance sheet as of ~~September 30, 2023,~~March 31, 2024, condensed consolidated statements of operations and comprehensive loss for the three ~~and nine~~ months ended ~~September 30,~~March 31, 2024 and 2023, ~~and 2022,~~ condensed consolidated statement of stockholders’ deficit for the three ~~and nine~~ months ended ~~September~~March 31, 2024 and 2023, and the

NOTES TO CONDENSED CONSOLIDATED STATEMENTS

~~30, 2023 and 2022, and the~~ condensed consolidated statements of cash flows for the ~~nine~~three months ended ~~September 30,~~March 31, 2024 and 2023 ~~and 2022~~ are unaudited, but include all adjustments, consisting only of normal recurring adjustments, which the Company considers necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The results for the three ~~and nine~~ months ended ~~September 30, 2023~~March 31, 2024 are not necessarily indicative of results to be expected for the year ending December 31, ~~2023~~2024 or for any future interim period. The condensed consolidated balance sheet at ~~December~~March 31, ~~2022~~2024 has been derived from audited financial statements; however, it does not include all of the information and notes required by U.S. GAAP for complete financial statements. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements for the year ended December 31, ~~2022~~2023 and notes thereto included in the Company’s annual report on Form 10-K (the ~~“2022~~“2023 Annual Report”), which was filed with the SEC on ~~February 28, 2023.~~March 5, 2024.

Use of Estimates

In preparing condensed consolidated financial statements in conformity with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of expenses during the reporting period. Due to inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in these estimates.

On an ongoing basis, the Company evaluates its estimates and judgments, including valuing equity securities in share-based payment arrangements, estimating the fair value of financial instruments recorded as derivative liabilities, useful lives of depreciable assets, and whether impairment charges may apply. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the reported amounts of revenues and expenses that are not readily apparent from other sources. Actual results could differ from those ~~estimates, particularly given the significant social and economic disruptions and uncertainties associated with the ongoing coronavirus pandemic (“COVID-19”) and the COVID-19 control responses.~~estimates.

Significant Accounting Policies

There have been no material changes in the Company’s significant accounting policies from those previously disclosed in the ~~2022~~2023 Annual ~~Report other than those discussed below.~~Report.

~~Sequencing~~

The Company adopted a sequencing policy under ASC 815-40-35 to determine if reclassification of contracts from equity to liabilities is necessary pursuant to ASC 815 due to the Company’s inability to demonstrate it has sufficient authorized shares. Certain contracts were classified as liabilities as the result of the instruments containing a potentially indeterminable number of shares and, most recently, due to the Company entering into agreements providing for the potential issuance of more shares than authorized. While temporary suspensions are in place to keep the potential exercises beneath the number authorized, certain instruments are classified as liabilities, after allocating available authorized shares on the basis of the earliest grant date of potentially dilutive instruments. Pursuant to ASC 815, issuance of stock-based awards to the Company’s employees, non-employees or directors are not subject to the sequencing policy.

On January 9, 2023, the Company filed a Certificate of Amendment of its Seventh Amended and Restated Certificate of Incorporation (the “Certificate of Amendment”) with the Secretary of the State of Delaware, which effected an increase in the Company’s authorized shares of common stock, from 1.2 billion to 1.7 billion, par value $0.001 per share. As a result of this increase in authorized shares, the liability-classified warrants were reclassified to equity. Approximately 141 million warrants, with a value of approximately $76.3 million, to purchase shares of the Company’s common stock were reclassified from liabilities to equity on January 9, 2023. The remaining balance of $1.0 million in warrant liability as of September 30, 2023 was related to certain conditional rights to independently purchase shares from the Company in a future raise of capital (the “Piggy-back Rights”).

~~Modification of Equity Classified Warrants~~

NOTES TO CONDENSED CONSOLIDATED STATEMENTS

the modification. When a modification is directly attributable to an equity offering, the incremental change in fair value of the warrants is accounted for as an equity issuance cost. When a modification is directly attributable to a debt offering, the incremental change in fair value of the warrants is accounted for as a debt discount or debt issuance cost. For all other modifications, the incremental change in fair value is recognized as a deemed dividend.

~~Convertible Notes under Fair Value Option~~

The Company accounts for certain convertible notes issued in August and September 2023 on an instrument-by-instrument basis under the fair value option (“FVO”) election of ASC Topic 825, Financial Instruments (“ASC 825”). The convertible notes accounted for under the FVO election are each debt host financial instruments containing embedded features wherein the entire financial instrument is initially measured at its issue-date estimated fair value and then subsequently remeasured at estimated fair value on a recurring basis at each reporting period date. Changes in the estimated fair value of the convertible notes are recorded as a component of Other (expense) income in the consolidated statements of operations, except that the change in estimated fair value attributable to a change in the instrument-specific credit risks is recognized as a component of other comprehensive income. As a result of electing the FVO, issuance costs related to the convertible notes are expensed as incurred.

Recently Issued Accounting Standards Not Yet Adopted

Compensation - Stock Compensation

In March 2024, the FASB issued ASU No. 2024-01, Compensation - Stock Compensation (Topic 718) - Scope Application of Profits Interest and Similar Awards, to clarify whether profits interest and similar awards should be accounted for in accordance with Topic 718, Compensation - Stock Compensation. The guidance applies to all business entities that issue profits interest awards as compensation to employees or nonemployees in exchange for goods or services. These amendments are effective for the Company for annual and interim periods in 2025, applied prospectively, with early adoption and retrospective application permitted. As the Company does not issue profit interest awards, the impact of the adoption of the amendments in this update is not expected to be material to the Company’s consolidated financial statements.

Improvements to Income Tax Disclosures

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09), which improves the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the effective tax rate reconciliation and income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. This guidance will be effective for the annual periods beginning the year ended December 31, 2025. Early adoption is permitted. Upon adoption, the guidance can be applied prospectively or retrospectively. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

Recently Issued Accounting Standards, Adopted

Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions

In June 2022, the FASB issued ASU 2022-03, ASC Subtopic 820 “Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions”. The FASB is issuing this Update (1) to clarify the guidance in Topic 820, Fair Value Measurement, when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security, (2) to amend a related illustrative example, and (3) to introduce new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with Topic 820.

For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance.

The Company ~~is still evaluating the impact~~adopted ASU 2022-03 effective January 1, 2024. The adoption of this ~~pronouncement~~guidance did not have a material impact on ~~the~~its condensed consolidated financial statements.

4. Fair Value Measurements

In accordance with ASC 820 (Fair Value Measurements and Disclosures), the Company uses various inputs to measure the fair value of liabilities related to certain embedded conversion features associated with convertible debt, share liability (receivable), and the contingent payable to Cognate BioServices on a recurring basis to determine the fair value of these liabilities. The Company also elects the ~~FVO~~fair value option (“FVO”) for certain eligible financial instruments, such as convertible notes, in order to simplify the accounting treatment.

ASC 820 establishes a hierarchy categorizing inputs into three levels used to measure and disclose fair value. The hierarchy gives the highest priority to quoted prices available in active markets and the lowest priority to unobservable inputs. An explanation of each level in the hierarchy is described below:

Level 1 - Unadjusted quoted prices in active markets for identical instruments that are accessible by the Company on the measurement date.

Level 2 - Quoted prices in markets that are not active or inputs which are either directly or indirectly observable.

~~Level 3 - Unobservable inputs for the instrument requiring the development of assumptions by the Company.~~

During the nine months ended September 30, 2023, the Company granted 20.2 million stock options (the “2023 Options”) with an exercise price ranging from $0.47 to $0.57 per share, to key external consultants who provide services to the Company. The 2023 Options contain both service and performance vesting conditions, which will vest over a service period, generally during the term of consulting agreement, or upon achievement of specific milestones.

An aggregate 153 million stock options held by Ms. Linda Powers, the Company’s Chief Executive Officer, and Mr. Leslie Goldman, the Company’s Senior Vice President, General Consul are subject to an agreement (the “Blocker Letter Agreement”) under which they cannot exercise any options or warrants except upon at least 61 days’ prior notice.

~~Restricted Stock Awards~~

~~Advent SOW 6~~

As previously reported, during April 2022, the Company’s Board approved, and the Company entered into a Statement of Work #6 (the “SOW 6”) with Advent BioServices, a related party of the Company, for five workstreams that are prerequisites for an application for regulatory approval of DCVax-L, for three required licenses for the Sawston facility and for drafting of key portions of the application for approval. The SOW provides for baseline costs and for one-time milestone incentives for successful completion of each of the workstreams, for the completion and submission of each application for product approval, and for obtaining regulatory approval of each of the three Sawston licenses. The milestone incentives will be a combination of cash and stock and are not paid until they are achieved. As also previously reported, the Company amended the SOW6 on September 26, 2022 (the “Amended SOW6”) to (1) extend the service period through September 30, 2023, and (2) clarify the assessment and application of the milestones, and (3) add a sixth workstream. (The potential cost for all unearned stock awards for milestones not yet achieved was re-measured on the modification date and will be further re-measured until the date the milestone award is achieved and the stock awards are earned.) If all of the 10 one-time milestones are achieved (i.e., for all six workstreams that are prerequisites for an application for product approval, for obtaining all three licenses required for the Sawston facility, and for the completion of key portions of the application for product approval), the aggregate stock-based compensation under the Amended SOW 6 will be 13.5 million shares (including the shares already earned and issued for the milestones already achieved) for an aggregate fair value of $10.1 million.

As of December 31, 2022, seven milestones were completed, including five workstreams and the regulatory approvals of two licenses required for the Sawston facility. An eighth milestone was partly completed and the stock component of that milestone was earned, but the cash portion of that eighth milestone was not yet earned.

On September 26, 2023, the Company further amended the SOW 6 (the “Second Amended SOW 6”) to extend the service period through March 31, 2024. As of the amendment date, the remaining unvested one-time milestone for submission of the application to MHRA for approval of DCVax-L was accounted as a Type I modification (probable to probable under FASB ASC Topic 718, Compensation—Stock Compensation (“ASC 718”). The previously remaining unrecognized compensation expense for total $17,000 is expected to be fully recognized by end of November 2023.

During the nine months ended September 30, 2023, milestones related to the workstream for Mechanism of Action, obtaining the commercial manufacturing license from the MHRA and completion of key portions of the application for product approval were completed. For this manufacturing license milestone, the Company recognized the remaining $0.5 million in expense in the condensed consolidated statements of operations and comprehensive loss and issued 3.0 million common shares. For the completion of the drafting of the MHRA application milestone, the Company recognized the remaining $0.1 million in expense in the condensed consolidated statements of operations and comprehensive loss and issued 1.5 million common shares.

~~Employee Compensation~~

In August 2023, the Company issued 0.6 million shares of common stock as a bonus payment to two staff employees. These shares were fully vested on the grant date. However, 0.3 million shares are subject to lock-up restrictions, prohibiting their sale or transfer within six months of the grant date. The Company recognized $0.3 million stock-based compensation which is based on the Company’s closing stock price on the grant date.

~~Other Service Agreement~~

During the nine months ended September 30, 2023, the Company issued 16,000 shares of Series C convertible preferred stock to an unrelated vendor who provided professional services for the Company. The fair value of the Series C convertible preferred stock on the issuance date was approximately $0.1 million, which will be expensed over a four-month service period. During the three and nine

8. Net Loss per Share Applicable to Common Stockholders

Basic loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the reporting period. Diluted loss per common share would be computed similar to basic loss per common share except that it reflects the potential dilution that could occur if dilutive securities or other obligations to issue common stock were exercised or converted into common stock. Because of the net loss from operations for each period, inclusion of such securities in the computation of loss per share would be anti-dilutive and thus they are excluded. Potentially dilutive weighted average common shares include common stock potentially issuable under the Company’s convertible notes and preferred stock, warrants and vested and unvested stock options.

The following securities were not included in the diluted net loss per share calculation because their effect was anti-dilutive as of the periods presented (in thousands):

9. Related Party Transactions

The Company had three operational programs with Advent: (a) an ongoing development and manufacturing program at the GMP facility in London, (b) an ongoing development and manufacturing program at the Sawston GMP facility, and (c) a one-time program for specialized work, organized into 10 sets of one-time milestones that were required for the MAA application, for the following:

●

Qualifying for and obtaining 3 required licenses for the Sawston facility: a license from the Human Tissue Authority to collect and process human cells and tissues, a license from the MHRA for manufacturing for clinical trials and compassionate use cases, and a license from the MHRA for commercial manufacturing.

●	6 workstreams relating to product matters required for anthe MAA application, ~~for regulatory approval of DCVax-L,~~ including Comparability, Stability, Potency, Product Profile, Mechanism of Action and Fill/Finish.

●	Drafting and submission of key portions of the application for product approval itself.

Table of Contents

NORTHWEST BIOTHERAPEUTICS, INC.

NOTES TO CONDENSED CONSOLIDATED STATEMENTS

Each of the three operational programs is covered by a separate contract. The ongoing manufacturing in the London facility is covered by a Manufacturing Services Agreement (“MSA”) entered into on May 14, 2018. The development and manufacturing program at the Sawston facility is covered by an Ancillary Services Agreement entered into on November 18, 2019. The specialized work associated with the 10 one-time milestones is covered by an SOW 6 entered into under the Ancillary Services Agreement as of April 1, 2022 and amended on September 26, 2022 and September 26, 2023. The 2023 amendment extended the SOW 6 service period for about 6 months, through March 31, 2024. Subsequently on April 1, 2024, the SOW 6 was further extended through September 30, 2024.

The Ancillary Services Agreement establishes a structure under which the Company and Advent negotiate and agree upon the scope and terms for Statements of Work (“SOWs”) for facility development activities and compassionate use program activities. After an SOW is agreed and approved by the Company, Advent will proceed with, or continue, the applicable services and will invoice the Company pursuant to the SOW. Since both the facility development and the compassionate use program involve pioneering and uncertainties in most aspects, the invoicing under the Ancillary Services Agreement is on the basis of costs incurred plus fifteen percent. The SOWs may involve ongoing activities or specialized one-time projects and related one-time milestone payments. The current Ancillary Services Agreement ended in ~~September~~July 2023. The Company subsequently extended the term by 12 months to July 2024 with no other changes.

SOW 6 provides for ongoing baseline costs for manufacturing at the Sawston facility and one-time milestone incentives for (a) regulatory approval of each of the 3 licenses required for the Sawston facility, (b) successful completion of each of the 6 workstreams and (c) completion of drafting key portions of an application for product approval. The milestone incentives are a combination of cash and stock, and are not paid until the milestone is achieved and earned.

During the nine months ended September 30, 2023, the Company paid an aggregate of $3.5 million in cash, of which $1.0 million was related to two milestones that were completed and fully expensed in 2022, but was unpaid as of December 31, 2022, and the other $2.5 million was payment for two completed one-time milestones (MAA workstream for mechanism of Action and obtaining a commercial manufacturing license from the MHRA on March 2023). The Company issued 4.5 million common shares as a result of completion of the two one-time milestones (obtaining a commercial manufacturing license from the MHRA and completion of drafting application) at fair value of $3.2 million, of which $0.6 million was recognized during the nine months ended September 30, 2023 and $2.6 million had already been recognized (but not paid) in 2022.

Warrant Modifications

~~Between January 10 and September 30, 2023,~~During the three months ended March 31, 2024, the Company amended multiple warrants whereby the maturity dates of certain warrants were extended for an additional approximately 3 months. The value of these modifications were calculated using the Black-Scholes-Merton option pricing model based on the following weighted average assumptions.

The incremental fair value attributable to the modified awards compared to the original awards immediately prior to the modification was calculated at ~~$2.2~~$1.8 million, of which ~~$0.8~~$1.2 million was associated with debt ~~financing~~amendments and was recognized as an additional debt discount under debt modification and ~~interest expense~~debt extinguishment loss under debt extinguishment (see Note 7), and the remaining ~~$1.4~~$0.6 million was treated as a deemed dividend and is reflected as “Deemed dividend related to warrant modifications” in the accompanying condensed consolidated statement of operations and comprehensive loss.

12. Commitments and Contingencies

Operating Lease- Lessee Arrangements

The Company has operating leases for corporate offices in the U.S. and U.K., and for manufacturing facilities in the U.K. Leases with an initial term of 12 months or less are not recorded in the balance sheet. The Company has elected the practical expedient to account for each separate lease component of a contract and its associated non-lease components as a single lease component, thus causing all fixed payments to be capitalized. The Company also elected the package of practical expedients permitted within the new standard, which among other things, allows the Company to carry forward historical lease classification. The lease renewal options have not been included in the calculation of the lease liabilities and right-of-use (“ROU”) assets as the Company has not yet determined whether to exercise the options. Variable lease payment amounts that cannot be determined at the commencement of the lease such as increases in lease payments based on changes in index rates or usage, are not included in the ROU assets or liabilities. These are expensed as incurred and recorded as variable lease expense.

At ~~September 30, 2023,~~March 31, 2024, the Company had operating lease liabilities of approximately ~~$4.5~~$4.6 million for both the 20-year lease of the building for the manufacturing facility in Sawston, U.K., and the current office lease in the U.S. and ROU assets of approximately ~~$4.0~~$4.1 million for the Sawston lease and U.S. office lease are included in the condensed consolidated balance sheet.

Operating Lease - Lessor Arrangements

On December 31, 2021, the Company entered into a Sub - lease Agreement (the “Agreement”) with Advent. The Agreement permits use by Advent of a portion of the space in the Sawston facility, which is leased by the Company under a separate head lease with a different counterparty (Huawei) that commenced on December 14, 2018. The Company subleased approximately 14,459 square feet of the 88,000 square foot building interior space, plus corresponding support space and parking. The lease payments amount under the Agreement are two times the amount payable by the Company under the head lease (which is currently L5.75 or approximately $7.26 per square foot based on exchange rate as of March 31, 2024), but subject to a cap of $10 per square foot. Accordingly, the monthly lease payments under the Sublease are based on $145,000 annually for 2024. The total lease payments paid by the Company to Huawei for the 88,000 square foot facility, exterior spaces and parking under the head lease are L550,000 (approximately $694,000) per year. The term of the Agreement shall end on the same date as the head lease term ends.

Advent BioServices Services Agreement

On May 14, 2018, the Company entered into a DCVax®-L Manufacturing and Services Agreement (“MSA”) with Advent BioServices, a related party which was formerly part of Cognate BioServices and was spun off separately as part of an institutional financing of Cognate. The MSA provides for manufacturing of DCVax-L products at an existing facility in London. The MSA is structured in the same manner as the Company’s prior agreements with Cognate BioServices. The MSA provides for certain payments for achievement of milestones and, as was the case under the prior agreement with Cognate BioServices, the Company is required to pay certain fees for dedicated production capacity reserved exclusively for DCVax production and pay for manufacturing of DCVax-L products for a certain minimum number of patients, whether or not the Company fully utilizes the dedicated capacity and number of patients. The MSA remains in force until five years after the first commercial sales of DCVax-L products pursuant to a marketing authorization, accelerated approval or other commercial approval, unless cancelled. Either party may terminate the MSA on twelve months’ notice, to allow for transition arrangements by both parties. During the notice period services would still be provided. Minimum required payments for this notice period are anticipated to total approximately £4.5 million ($~~5.5~~5.7 million).

The Company entered into SOW 6 with Advent, which was incorporated into the Ancillary Services Agreement, on April 1, 2022, and amended it on September 26, 2022 and again on September 26, 2023. The milestone incentives involve a combination of cash and stock and are not paid until they are achieved and earned, as described in Note9.

German Tax Matter

The German tax authorities have audited our wholly owned subsidiary, NW Bio GmbH, for ~~2013-2015 and assessed additional tax against the subsidiary.~~2013-2015. The NW Bio GmbH submitted substantial documentation to refute certain aspects of the assessments and the German tax authorities agreed in principle with the Company’s proposed revised approach and settlement offer. A final settlement bill was received from the German Tax Authority confirming that only a portion of the original bill was owed, €277,000 (approximately ~~$293,000)~~$299,000), for corporate taxes, interest, and reduced penalty for the period under audit, which the Company paid on September 2, 2021. The Company also received and paid the final settlement bill from the local authority for trade taxes for the audit period in the amount of €231,000 (approximately ~~$244,000)~~$249,000). On November 4, 2021, the Company received a letter from the local tax authorities asking for additional late fees of €513,000 (now approximately ~~$542,000)~~$554,000) on reimbursable withholding taxes that had been waived during the settlement process. On December 8, 2021, the Company appealed the assessment of additional late fees. Additionally,

~~NOTES TO CONDENSED CONSOLIDATED STATEMENTS~~

the Company requested that NW Bio GmbH be deregistered from the trade register, as it no longer had current operations. The deregistration was granted effective December 31, 2021. Between January 2022 and July 2022, the Company received tax bills for the corporate and trade taxes for the 2016-2020 tax years that totaled approximately €222,000 (approximately ~~$235,000)~~$240,000). On July 27, 2022, the Company was informed that the German Tax Authorities were prepared to waive €135,000 (approximately ~~$143,000)~~$146,000) of the penalties. The Company offered to pay this reduced penalty if an

extended payment plan was approved. A response was received dated November 14, 2022 indicating that the tax authority would not be able to grant a further deferral of payment of these penalties. In a letter dated December 27, 2022, the Leipzig tax authority sent letters to the former and current managing directors of NW Bio GmbH giving 30 days to respond to a tax liability questionnaire. Based on the responses to the liability questionnaires the tax authorities have currently not directed any further measures against former and current managing directors of NW Bio GmbH with respect to tax liability proceedings. ~~The Company currently has accrued for the current amounts owed for these penalties of €377,000 (approximately $399,000) as well as for all unpaid taxes as of September 30, 2023. Subsequently on~~On October 12, 2023 and January 16, 2024, the Company ~~paid~~made €189,000 and €189,000 payments, respectively, regarding to the late payment penalty. As of March 31, 2024, the Company accrued for trade tax liability of €155,000 (approximately ~~$200,000), which represents 50%~~$168,000) and corporation tax of ~~the total penalties. The Company is expecting to make the other half payment by end of November 2023.~~€99,000 (approximately $107,000). Based on the Company’s current operating state in Germany and the negotiations, the Company believes, based on its evaluation under ASC 740, that the resolution of these tax matters will not likely result in a net material charge to the Company.

Other Contingent Payment Obligation

~~Between May and September 2023,~~During the three months ended March 31, 2024, the Company entered into ~~certain~~a non-dilutive funding ~~agreements~~agreement with ~~multiple investors,~~an individual investor, pursuant to which the Company received funding of ~~$4.6 million~~$50,000 related to a gain contingency.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited condensed consolidated financial statements and the notes to those statements included with this report. In addition to historical information, this report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Such forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those projected. The words “believe,” “expect,” “intend,” “anticipate,” and similar expressions are used to identify forward-looking statements, but some forward-looking statements are expressed differently. Many factors could affect our actual results, including those factors described under “Risk Factors” in our Form 10-K for the year ended December 31, ~~2022~~2023 and in Part II Item 1A of this report. These factors, among others, could cause results to differ materially from those presently anticipated by us. You should not place undue reliance on these forward-looking statements.

Overview

We are a biotechnology company focused on developing personalized immune therapies for cancer. We have developed a platform technology, DCVax®, which uses activated dendritic cells to mobilize a patient’s own immune system to attack their cancer.

Our lead product, DCVax®-L, is designed to treat solid tumor cancers in which the tumor can be surgically removed. We have completed a 331-patient international Phase III trial of DCVax-L for ~~glioblastoma~~Glioblastoma multiforme brain cancer (GBM).

~~The trial~~, published the results ~~were presented at a scientific conference~~ in ~~May 2022, and were reported in a~~the JAMA Oncology peer reviewed ~~publication in JAMA Oncology,~~journal, and on December 20, 2023 we submitted a ~~top scientific and medical journal.~~

In June 2023, the Company presented substantial information from analyses conducted by independent experts on the underlying biology and mechanism of action of its DCVax technology at an Industry Theater presentation during the ASCO (American Society of Clinical Oncology) conference. The Company is pursuing further analyses by independent experts and plans to present further information at an appropriate future conference.

~~The Company is now~~Marketing Authorization Application (MAA) for commercial approval in the ~~final stages of preparing an application to the~~ U.K. ~~regulatory authority for approval of DCVax-L. The Company is working with teams of specialized consultants on preparation of the application package as well as related activities.~~

In parallel with preparing the application for approval of DCVax-L, the Company is working with the contract research organization (CRO) and with specialized consultants on preparing the Trial Master File and trial sites to be inspection-ready for regulators.

~~The Company and the CRO continue to conduct long-term follow-up in connection with the Phase III trial of DCVax-L, as there are still patients alive.~~

~~The Company is pursuing preparations for the pediatric clinical trials that are required to be conducted in connection with an application for approval of a new medicine for adult patients.~~

The non-proprietary name for the Company’s DCVax-L product, murcidencel, was finalized and published in rINN List 90 in October 2023. The name was originally assigned by the WHO on May 6, 2022, and then had to go through a series of additional steps and notice periods to become final.

The Company and Advent are working together to prepare for potential commercial operations. The buildout of Phase 1B of the Sawston facility, which had been under way since last year, has been completed. On July 24, 2023, the Company changed the name of its UK subsidiary from Aracaris Limited to Northwest Biotherapeutics Limited.

The Company’s wholly owned subsidiary, Flaskworks, is continuing its development work to optimize a system for closed and automated manufacturing of DCVax-L products, including to optimize yields. The Company views this as a centerpiece of efforts toward scale-up for potential commercial operations.

Supply chain issues and equipment backlogs continue to be factors affecting operations both for Advent and for Flaskworks. This includes months-long backlogs for certain equipment and materials. However, the work is progressing in spite of the backlogs.

~~Table of Contents~~

~~The Company is in active discussions in regard to certain combination treatment regimens and is planning for certain strategic trials with such combination treatments.~~

~~In the future, we~~We plan to conduct clinical trials of DCVax-L for other ~~types of~~ solid tumor cancers ~~beyond brain cancer,~~in the future, when resources permit. Our second product, DCVax®-Direct, is designed to treat inoperable solid tumors. A 40-patient Phase I trial has been completed, and it included treatment of a diverse range of more than a dozen types of cancers. We plan to work on preparations for Phase II trials of DCVax-Direct as resources permit. We

The Company’s programs and operations continue to be impacted by supply chain issues and backlogs which, surprisingly, have still not substantially resolved. These involve service firms and also vendors and suppliers of a wide variety of items, ranging from major equipment to particular reagents required for the manufacturing process. Shortages of certain key materials and supplies have also occurred. The Company is hopeful that the various backlog circumstances will improve over the course of 2024.

During the first quarter of 2024, the Company continued its progress on multiple fronts, including the following.

MAA Application. As previously reported, the Company filed a Marketing Authorization Application (MAA) to the U.K. Medicines and Healthcare Products Regulatory Agency (MHRA) on December 20, 2023, seeking regulatory approval for commercialization of DCVax - L for newly diagnosed and recurrent Glioblastoma (GBM). On January 24, 2024 the Company received notification from the MHRA that the MAA had passed validation. On March 7, 2024, the Company received notification from the MHRA that the validation was confirmed. The Company did not make any amendment or addition to its MAA after the original December 20, 2023 submission.

As is typical, the Company does not plan to make any interim announcements while its MAA is going through the regulatory process. The Company will announce the results when the regulatory review and decision - making about the MAA is complete.

Preparations for Regulatory Inspections. As anticipated in the Company’s prior reports, preparations for regulatory inspections associated with the MAA have continued to be a major focus of the Company’s activities this year to date. The Company has continued working intensively with teams of expert consultants in both the U.S. and U.K. on these preparations, and has also arranged for further mock inspections by specialists who were formerly inspectors for regulatory agencies. It is anticipated that teams of multiple inspectors for extended periods will conduct comprehensive inspections of all the key parties involved conducting in the Phase 3 trial and of all documentation and records. The Company does not know when MAA - related inspections may take place.

Pediatric Glioma Clinical Trials. The Company continued its discussions with physicians about the two planned trials of DCVax - L for pediatric gliomas. The arrangements for the trials have not yet been finalized.

Table of Contents

Flaskworks. The Flaskworks team and Advent BioServices continued to work with the specialized contractor on the development of the GMP-grade units of the Flaskworks system. Two key areas of focus in the work have been the ability to clean the machines to GMP requirements and additional safety features for protection of the operators in the GMP setting. Enabling all parts of the machines to be cleanable to the level of sterility required for GMP operations has required changing certain materials to achieve acceptable surface properties, constructing housings around certain portions of the machines or otherwise eliminating nooks and crannies while not interfering with the movements of the machines, and other such development aspects. The Company believes the work is on track for the GMP adaptation work to be finished in the near future, and the first GMP units to be delivered to the Company soon after that.

Sawston Facility. The Company has commenced the design and build works for the construction of the first Grade C cleanroom at the Sawston facility and the contractor is onsite. The Company expects the Grade C cleanrooms to be important for scale - up, as they will accommodate the “closed” Flaskworks system, and be able to manufacture a number of patients’ products in the lab at the same time. In contrast, with the existing “open” process in the Grade B cleanrooms, products must be manufactured for one patient at a time and the whole lab must be cleaned and sterilized between each patient’s process. Since construction work in the facility can directly and/or indirectly impact the existing cleanrooms in the facility (e.g., by generating a lot of dust and particles) and prevent the existing Grade B cleanrooms from being able to operate in accordance with GMP sterility standards, the Company has been working with Advent BioServices and contractors to arrange for the construction work to take place as much as possible during periodic scheduled shutdowns of the existing clean rooms for deep cleaning and special maintenance which are ~~pursuing~~required for GMP compliance.

Intellectual Property and Collaborations. As previously reported, the ~~prosecution of existing~~Company filed new patent applications relating to the Flaskworks system, which the Company believes will be an important factor for facilitating scale - up and ~~adding~~commercialization of DCVax - L products. In addition, multiple new patents were granted and 1 new patent was allowed from patent applications previously filed. The Company continued working with certain intellectual property that ~~we consider complementary~~it has in - licensed as previously reported, on preparations for expansion of the Company’s pipeline with certain new clinical programs when bandwidth and resources permit. The Company also continued discussions and negotiations during the first quarter of 2024 relating to ~~our existing intellectual property.~~collaborations which the Company believes will help it build a broad franchise in dendritic cell-based immunotherapies.

Litigation. Significant amounts of Company bandwidth and resources were spent on litigations during the first quarter of 2024 (and to date in the second quarter of 2024). The cases are described in Part II - Item 1, Legal Proceedings, below.

Annual Shareholder Meeting. The Company plans to conduct its Annual Shareholder Meeting before the end of June 2024.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect our reported amounts of assets, liabilities, revenues and expenses.

On an ongoing basis, we evaluate our estimates and judgments, including those related to derivative liabilities, accrued expenses and stock-based compensation. We based our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the reported amounts of revenues and expenses that are not readily apparent from other sources. Actual results could differ from those estimates, particularly given the significant social and economic disruptions and uncertainties associated with the lingering effects from the coronavirus pandemic (“COVID-19”) and the COVID-19 control responses.estimates.

Our critical accounting policies and significant estimates are detailed in our Annual Report on Form 10-K for the year ended December 31, ~~2022.~~2023. Our critical accounting policies and significant estimates have not changed substantially from those previously disclosed in our Annual Report on Form 10-K for the year ended December 31, ~~2022 other than those included below.~~

~~Sequencing~~

The Company adopted a sequencing policy under ASC 815-40-35 to determine if reclassification of contracts from equity to liabilities is necessary pursuant to ASC 815 due to the Company’s inability to demonstrate if it has sufficient authorized shares. Certain contracts were classified as liabilities as the result of the instruments containing a potentially indeterminable number of shares and, most recently, due to the Company entering into agreements providing for the potential issuance of more shares than authorized. While temporary agreements are in place to keep the potential exercises beneath the number authorized, certain instruments are classified as liabilities, after allocating available authorized shares on the basis of the earliest grant date of potentially dilutive instruments. Pursuant to ASC 815, issuance of stock-based awards to the Company’s employees, non-employees or directors are not subject to the sequencing policy.

~~Modification of Equity Classified Warrants~~

A change in the terms or conditions of a warrant is accounted for as a modification. For a warrant modification accounted for under ASC 815, the effect of a modification shall be measured as the difference between the fair value of the modified warrant over and the fair value of the original warrant immediately before its terms are modified, with each measured on the modification date. The accounting for any incremental fair value of the modified warrants over the original warrants is based on the specific facts and circumstances related to the modification. When a modification is directly attributable to an equity offering, the incremental change in fair value of the warrants is accounted for as an equity issuance cost. When a modification is directly attributable to a debt financing, the incremental change in fair value of the warrants is accounted for as a debt discount or debt issuance cost. For all other modifications, the incremental change in fair value is recognized as a deemed dividend.

~~Convertible Notes under Fair Value Option~~

~~Table of Contents~~

under the FVO election are each debt host financial instruments containing embedded features wherein the entire financial instrument is initially measured at its issue-date estimated fair value and then subsequently remeasured at estimated fair value on a recurring basis at each reporting period date. Changes in the estimated fair value of the convertible notes are recorded as a component of Other (expense) income in the consolidated statements of operations, except that the change in estimated fair value attributable to a change in the instrument-specific credit risks is recognized as a component of other comprehensive income. As a result of electing the FVO, issuance costs related to the convertible notes are expensed as incurred.

Results of Operations

Operating costs:

Our operating costs and expenses consist primarily of research and development (R&D) expenses. R&D expenses include clinical trial expenses, and increased costs after completion of a Phase III trial, especially for the extensive preparations, and teams of expert consultants, required for an application for product approval.

Table of Contents

In addition to clinical trial and post-trial costs, our operating costs may include ongoing work relating to our DCVax products, including R&D, product characterization, manufacturing process development, quality control process development, and related matters. Additional substantial costs relate to the development and expansion of manufacturing capacity.

Our operating costs also include the costs of preparations for the launch of new or expanded clinical trial programs, such as our anticipated trials of combination treatment regimens. The preparation costs include payments to regulatory consultants, lawyers, statisticians, sites and others, evaluation of potential investigators, the clinical trial sites and the CROs managing the trials and other service providers, and expenses related to institutional approvals, clinical trial agreements (business contracts with sites), training of medical and other site personnel, trial supplies and other.

Our operating costs also include legal and accounting costs in operating the Company.

The foregoing operating costs include the costs for Flaskworks’ ongoing operations and intellectual property filings, and the operations of our subsidiaries in the U.K., the Netherlands and Germany.

Research and development:

R&D expenses include costs for substantial external scientific personnel, technical and regulatory advisers, and others, costs of laboratory supplies used in our internal research and development projects, travel, regulatory compliance, and expenditures for preclinical and clinical trial operation and management when we are actively engaged in clinical trials.

Because we are a pre-revenue company, we do not allocate R&D costs on a project basis. We adopted this policy, in part, due to the unreasonable cost burden associated with accounting at such a level of detail and our limited number of financial and personnel resources.

General and administrative:

General and administrative expenses include personnel related salary and benefit expenses, cost of facilities, insurance, travel, legal services, property and equipment and amortization of stock options and warrants.

We incurred $1.5 million and $12.0 million R&D expense related to one-time milestone activities under the SOW 6 with Advent BioServices for the nine months ended September 30, 2023 and 2022, respectively. Advent had completed 7 out of the total 10 one-time milestones as of December 31, 2022, and the majority of the one-time R&D expense was recognized in 2022. Therefore, we only expensed $1.5 million for the nine months ended September 30, 2023 related to the remaining 3 milestones. During the nine months ended September 30, 2022, we expensed $5.3 million (but only paid $1.5 million) for one-time cash milestones and $6.7 million (but only issued 2.5 million shares of common stock at fair value of $2.1 million) for one-time stock-based milestones that we believe are probable to be achieved and hence to become payable during the contract period.

~~General and Administrative Expense~~

For the nine months ended September 30, 2023 and 2022, general and administrative expenses were $21.6 million and $23.9 million, respectively. The decrease in 2023 was mainly related to a decrease of $1.7 million in consulting, legal and stock-based compensation, and $0.7 million reduction in our D&O insurance.

~~Change in Fair Value of Derivatives~~

~~We recognized a non-cash~~ gain of $3.9 million and a non-cash loss of $15.9 million for the nine months ended September 30, 2023 and 2022, respectively. The gain was mainly due to majority of revaluation expense was recognized as of January 9, 2023, when we reclassed all warrants from liability classified to equity classified. The stock price on January 9, 2023 and December 31, 2022 was $0.71 and $0.78 per share, respectively. The decrease of stock price resulted a gain in change in fair value.

~~The 2022 loss was primarily due to the extension of certain warrants and an increase of stock price as of September 30, 2022 compared to December 31, 2021.~~

~~Debt Extinguishment~~

During the nine months ended September 30, 2023, we issued approximately 27.6 million shares of common stock with a fair value of $17.5 million to certain lenders in lieu of cash payments of $13.2 million of debt, including $1.0 million of accrued interest. We also extinguished Share liabilities of $1.3 million and recognized additional $0.5 million in Share liabilities. We recognized an approximately $3.5 million debt extinguishment loss during the nine months ended September 30, 2023 from the debt redemption.

During the nine months ended September 30, 2023, we issued approximately 56,000 shares of Series C preferred stock with a fair value of $1.0 million to certain lenders in lieu of cash payments of $0.9 million in debt, including $0.1 million of accrued interest. We recognized an approximately $0.1 million debt extinguishment loss.

~~Interest Expense~~

During the nine months ended and September 30, 2023 and 2022, we recorded interest expense of $4.0 million and $4.8 million, respectively. The decrease in interest expense in 2023 was mainly related to a decrease of outstanding debt as a result of the redemption of approximate $18.1 million debt in 2022.

~~Foreign currency transaction loss~~

~~During the nine months ended and September 30, 2023 and 2022, we recognized foreign currency transaction loss of $0.1 million and $6.8 million, respectively. The loss~~ was due to the ~~strengthening~~weakening of the U.S. dollar relative to the British pound sterling.

Liquidity and Capital Resources

We have experienced recurring losses from operations since inception. We have not yet established an ongoing source of revenues and must cover our operating expenses through debt and equity financings to allow us to continue as a going concern. Our ability to continue as a going concern depends on the ability to obtain adequate capital to fund operating losses until we generate adequate cash flows from operations to fund our operating costs and obligations. If we are unable to obtain adequate capital, we could be forced to cease operations.

~~Table of Contents~~

We depend upon our ability, and will continue to attempt, to secure equity and/or debt financing. We cannot be certain that additional funding will be available on acceptable terms, or at all. Our management determined that there was substantial doubt about our ability to continue as a going concern for at least one year after the annual consolidated financial statements were issued, and management’s concerns about our ability to continue as a going concern within the year following this report persist.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk represents the risk of loss that may result from the change in value of financial instruments due to fluctuations in its market price. Market risk is inherent in all financial instruments. Market risk may be exacerbated in times of trading illiquidity when market

~~Table of Contents~~

participants refrain from transacting in normal quantities and/or at normal bid-offer spreads. Our exposure to market risk is directly related to derivatives, debt and equity linked instruments related to our financing activities.

Our assets and liabilities are overwhelmingly denominated in U.S. dollars. We do not use foreign currency contracts or other derivative instruments to manage changes in currency rates. We do not now, nor do we plan to, use derivative financial instruments for speculative or trading purposes. However, these circumstances might change.

The primary quantifiable market risk associated with our financial instruments is sensitivity to changes in interest rates. Interest rate risk represents the potential loss from adverse changes in market interest rates. We use an interest rate sensitivity simulation to assess our interest rate risk exposure. For purposes of presenting the possible earnings effect of a hypothetical, adverse change in interest rates over the 12-month period from our reporting date, we assume that all interest rate sensitive financial instruments will be impacted by a hypothetical, immediate 100 basis point increase in interest rates as of the beginning of the period. The sensitivity is based upon the hypothetical assumption that all relevant types of interest rates that affect our results would increase instantaneously, simultaneously and to the same degree. We do not believe that our cash and equivalents have significant risk of default or illiquidity.

The sensitivity analyses of the interest rate sensitive financial instruments are hypothetical and should be used with caution. Changes in fair value based on a 1% or 2% variation in an estimate generally cannot be extrapolated because the relationship of the change in the estimate to the change in fair value may not be linear. Also, the effect of a variation in a particular estimate on the fair value of financial instruments is calculated independent of changes in any other estimate; in practice, changes in one factor may result in changes in another factor, which might magnify or counteract the sensitivities. In addition, the sensitivity analyses do not consider any action that we may take to mitigate the impact of any adverse changes in the key estimates.

Based on our analysis, as of ~~September 30, 2023,~~March 31, 2024, the effect of a 100+/- basis point change in interest rates on the value of our financial instruments and the resultant effect on our net loss are considered immaterial.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation as of ~~September 30, 2023,~~March 31, 2024, of the design and operation of our disclosure controls and procedures, as such terms are defined in Exchange Act Rules 13a-15(e) and 15d-15(e). Based on this evaluation, management concluded that, as of such date, our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Remediation of a Material Weakness in Internal Control over Financial Reporting

The Company recognizes the importance of internal controls to ensure accurate financial reporting. Consequently, we designed and implemented remediation measures to address the material weakness previously identified during the quarter ended December 31, 2023, which was due solely to the material weakness over the valuation of debt and derivative liabilities which primarily involved applying an incorrect valuation method using the market price actually paid for certain convertible notes rather than using a Monte Carlo valuation formula. In light of the material weakness, we enhanced our valuation of debt and derivative liability processes. Based on the actions taken, as well as the evaluation of the design of the new controls, we concluded that the controls were operating effectively as of March 31, 2024. As a result, management concluded that the material weakness was remediated as of March 31, 2024.

Changes in Internal Control over Financial Reporting

No change in internal control over financial reporting occurred during the most recent quarter with respect to our operations, which materially affected, or is ~~reasonable~~reasonably likely to materially affect, our internal controls over financial reporting.

Part II - Other Information

Item 1. Legal Proceedings

On December 1, 2022, we filed a Complaint in the United States District Court for the Southern District of New York against certain market makers. The Complaint alleges that the defendants engaged in manipulation of the Company’s stock, in violation of the Securities Exchange Act of 1934 and common law fraud, over a period of years. On March 20, 2023, the defendants filed a Motion to Dismiss the Complaint. On April 10, 2023 we filed an Amended Complaint against Canaccord Genuity LLC, Citadel Securities LLC, G1 Execution Services LLC, GTS Securities LLC, Instinet LLC, Lime Trading Corp., and Virtu Americas LLC (~~Northwest~~(Northwest Biotherapeutics Inc. v. Canaccord, et al., No. 1:22-cv-10185-GHW-GWG).

Following defendant’s filing of a new Motion to Dismiss (MTD) and various filings on both sides, an oral argument on defendants’ latest Motion to Dismiss was held on November 14, 2023. The Magistrate Judge issued an 85 page Recommendation and Results Opinion (R&R) for review by the Senior Judge. The Magistrate Judge found that the Company had adequately plead all of the elements of its claim of market manipulation, with the exception of producing enough details for calculating actual damages, known as loss causation. On that basis, he granted defendant’s motion to dismiss without prejudice, subject to the Company’s right to replead on just the question of loss causation, finding that such a filing would “not be futile”.

On February 14, 2024, the Senior Judge issued an opinion accepting all the recommendations and findings of the R&R, and gave the Company 30 days to file this limited repleading amendment on loss causation and damages no later than March 15, 2024. On March 15, 2024, the Company filed their more detailed repleading on loss causation and damages. At the end of March, defendants asked for the right to object to the Judge’s findings against them on December 29, 2023 and February 14, 2024. This motion was denied. The defendants then asked for leave to file a new MTD. That motion was granted with a 30 day filing requirement for defendants and a 30 day response time for the Company.

On May 1, 2024 the defendants filed their new MTD. The Company is currently drafting its response, and plans to continue to pursue this case vigorously.

As previously reported, three stockholders filed in the Delaware Court of Chancery three similar derivative lawsuits against the Company and certain of its directors and officers, including J. Cofer Black, Marnix L. Bosch, Alton L. Boynton, Leslie J. Goldman, Jerry Jasinowski, Navid Malik, and Linda F. Powers (the “Individual Defendants”), alleging the Individual Defendants (i) breached their fiduciary duties, and (ii) were unjustly enriched by director and officer compensation awarded in 2020 to the Individual Defendants—notwithstanding the fact that approximately 90% of shareholders voted to approve of the Company’s executive compensation (the same compensation that these three stockholders are seeking to challenge) twice (both through its Say on Pay vote at the Company’s Annual Meeting in 2021, and again in a binding vote at the Company’s Annual Meeting in 2022) and approximately 90% of shareholders also voted to approve the director awards ~~were subject to shareholder approval.~~at the 2022 Annual Meeting. On March 31, 2022, the Delaware Court of Chancery consolidated these actions into a single action under the caption In re Northwest Biotherapeutics, Inc. Stockholder Litigation (the “Derivative Action”).

On December 30, 2022, ~~shareholders again approved~~following the ~~same 2020 executive compensation with approximately 90%~~shareholder approvals at the December 2022 Annual Meeting, the Plaintiff filed an Amended Complaint asserting that the shareholder votes should be deemed ineffective. On February 22, 2023, the Individual Defendants and the Company filed a Motion to Dismiss the Amended Complaint. On November 17, 2023, the court issued an oral decision denying the Motion to Dismiss. On December 20, 2023, Gibson Dunn filed an answer to the Consolidated Amended Complaint on behalf of the ~~votes, and also approved~~Company. On December 28, 2023, the ~~directors compensation with approximately 90%~~Individual Defendants, represented by separate counsel, filed their response to the Consolidated Amended Complaint. The parties are currently in the midst of ~~the votes.~~
