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 prerequisites and preparations for filing an application for regulatory approval of the product.

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 $25.1 million for the six months ended June 30, 2023. The Company used approximately $22.8 million of cash in its operating activities during the six months ended June 30, 2023.

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.

NOTES TO CONDENSED CONSOLIDATED STATEMENTS

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 June 30, 2023, condensed consolidated statements of operations and comprehensive loss for the three and six months ended June 30, 2023 and 2022, condensed consolidated statement of stockholders’ deficit for the three and six months ended June 30, 2023 and 2022, and the condensed consolidated statements of cash flows for the six months ended June 30, 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 six months ended June 30, 2023 are not necessarily indicative of results to be expected for the year ending December 31, 2023 or for any future interim period. The condensed consolidated balance sheet at December 31, 2022 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 and notes thereto included in the Company’s annual report on Form 10-K (the “2022 Annual Report”), which was filed with the SEC on February 28, 2023.

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.

Significant Accounting Policies

There have been no material changes in the Company’s significant accounting policies from those previously disclosed in the 2022 Annual Report other than those discussed 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 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, nonemployees 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 $1.1 million in warrant liability as of June 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”).

NOTES TO CONDENSED CONSOLIDATED STATEMENTS

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 and the fair value of the original warrant immediately before its terms are modified, with each measured on the modification date. The accounting for 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 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.

Recently Issued Accounting Standards Not Yet 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 of this pronouncement on the 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 outstanding warrants, certain embedded conversion features associated with convertible debt and the contingent payable to Cognate BioServices on a recurring basis to determine the fair value of these liabilities. 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.

The Company accounted for the Piggy-back Rights as a freestanding financial instrument, which was classified as a liability at fair value on the Condensed Consolidated Balance Sheet

On January 9, 2023, the Company reclassified the fair value of the warrant liability of $76.3 million into the additional paid-in capital. The change in fair value of the common stock warrant liability of $2.3 million between December 31, 2022 and January 9, 2023 is reflected in “Change in fair value of derivative liabilities” in the accompanying condensed consolidated statements of comprehensive loss for the six months ended June 30, 2023.

Restricted Stock Awards

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 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. On September 26, 2022, the Company amended the SOW6 (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 of the 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.

During the six months ended June 30, 2023, the eighth milestone workstream for Mechanism of Action and the milestone for obtaining the commercial manufacturing license from the MHRA 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 remaining one-time milestone that is anticipated to be achieved and earned in the future, the Company recognized and expensed (but did not issue) the pro-rata portion of the remaining potential milestone stock awards during the three and six months ended June 30, 2023, of $40,000 and $0.1 million, respectively.

Other Service Agreement

On March 16, 2023, the Company issued 8,000 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 six months ended June 30, 2023, the Company recognized approximately $89,000 and $0.1 million, respectively as part of general and administrative expenses.

On March 2, 2023, the Company entered into a Commercial Loan Agreement (the “Commercial Loan”) with a commercial lender for an aggregate principal amount of $11.0 million. The Commercial Loan bears interest at 8% per annum with a 22-month term. There are no principal repayments during the first eight months of the term. The Commercial Loan is amortized in 14 installments starting on November 2, 2023. The Commercial Loan carries an original issue discount of $1.0 million.

In April 2023, the Company entered into several ten-month convertible notes (the “April Convertible Notes”) with multiple investors (the “Holders”) with an aggregate principal amount of $0.9 million for a purchase price of $0.8 million. The April Convertible Notes bear interest at 8% per annum, and are convertible into Series C preferred shares at $13.75 per share at the Holders’ sole option. The Series C preferred shares are convertible into common stock 30 days after the debt conversion date. Each Series C preferred share is convertible into 25 shares of common stock. The Company reclassed $0.7 million Investor advances that was received from the Holders in December 2022 to Convertible notes payable on the condensed consolidated balance sheet as of June 30, 2023. As a result, the Company received net cash proceeds of $0.1 million.

NOTES TO CONDENSED CONSOLIDATED STATEMENTS

As consideration for entering into the convertible note agreements, the Company also agreed to amend the investors’ existing outstanding warrants. The exercise price of certain warrants was amended from $2.00 per share to $0.55 per share, and the maturity date was extended for additional 9 months. The incremental change in fair value resulting from the amendment was approximately $0.2 million, which was recognized as an additional debt discount to the April Convertible Notes.

On June 30, 2023, the Company entered into a one-year convertible note (the “June Convertible Note”) with an individual investor (the “Holder”) with an aggregate principal amount of $1.0 million. The Company received $1.0 million cash from the June Convertible Note. The June Convertible Note bears interest at 8% per annum, and is convertible into Series C preferred shares at $12.50 per share at the Holder's sole option. The Series C preferred shares are convertible into common stock 30 days after the debt conversion date. Each Series C preferred share is convertible into 25 shares of common stock.

During the six months ended June 30, 2023, the Company issued approximately 15.2 million shares of common stock with a fair value of $9.6 million to certain lenders in lieu of cash payments of $7.4 million of debt, including $0.7 million of accrued interest. In addition, pursuant to exchange agreements executed with various holders, the Company is required to potentially issue additional common stock (the “Share liability”) if the stock price is less than the price defined in the exchange agreement as of the true-up date. During the six months ended June 30, 2023, the Company extinguished Share liabilities of $1.1 million and recognized an additional $0.7 million in Share liabilities. The Company recognized an approximately $1.8 million debt extinguishment loss during the six months ended June 30, 2023 from the debt redemption.

During the six months ended June 30, 2023, the Company recognized $0.8 million change in fair value of embedded redemption option as this embedded feature had de minimis value based on the remaining life of the note and the next qualified financing.

During the six months ended June 30, 2023, the Company 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. The Company recognized an approximately $0.1 million debt extinguishment loss.

For the three months ended June 30, 2023 and 2022, interest expense related to outstanding debt totaled approximately $1.3 million and $1.4 million including amortization of debt discounts totaling $0.7 million and $0.7 million, respectively.

For the six months ended June 30, 2023 and 2022, interest expense related to outstanding debt totaled approximately $2.3 million and $3.3 million including amortization of debt discounts totaling $1.3 million and $1.5 million, respectively.

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 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, 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 an application for regulatory approval of DCVax-L, including Comparability, Stability, Potency, Product Profile, Mechanism of Action and Fill/Finish.
Drafting of key portions of the application for product approval itself.

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.

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 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 six months ended June 30, 2023, the Company paid an aggregate of $2.0 million in cash, of which $1.0 million was related to two milestones that were completed and fully expensed but unpaid as of December 31, 2022, and the other $1.0 million was partial payment for one milestone (obtaining a commercial manufacturing license from the MHRA) that was completed as of March 20, 2023. The Company issued 3.0 million common shares as a result of completion of the one-time milestone (obtaining a commercial manufacturing license from the MHRA) at fair value of $2.1 million, of which $0.5 million was recognized during the six months ended June 30, 2023 and $1.6 million had already been recognized (but not paid) in 2022. During the six months ended June 30, 2023, the Company also expensed (but did not pay) an aggregate of $0.5 million related to completed cash milestone payments; the Company also expensed (but did not pay) an aggregate of $0.2 million related to future cash milestone payments that the Company anticipates will be

Advent BioServices Sublease Agreement

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 exterior 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  £5.75 or approximately $7.28 per square foot based on exchange rate as of June 30, 2023), 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 2023. 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 £500,000 (approximately $633,000) per year. The term of the Agreement shall end on the same date as the head lease term ends.

10. Preferred Stock

Series C Convertible Preferred Stock

During the six months ended June 30, 2023, the Company entered into various Subscription Agreements (the “Series C Subscription Agreements”) with certain investors (the “Series C Investors”). Pursuant to the Series C Subscription Agreements, the Company issued the Series C Investors an aggregate of 0.3 million shares of the Company’s Series C convertible preferred stock, par value $0.001 per share (the “Series C Shares”), at a weighted purchase price of $14.69 per share for proceeds of approximately $4.8 million.

During the six months ended June 30, 2023, the Company issued approximately 56,000 Series C Shares 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 accrued interest. The Company recognized an approximately $0.1 million debt extinguishment loss.

During the six months ended June 30, 2023, approximately 0.3 million Series C Shares with a book value of $3.6 million were converted into 6.4 million common shares at a ratio of 1:25.

The Company determined that the Series C Shares contain contingent redemption provisions allowing redemption by the holder upon certain defined events (“deemed liquidation events”). As the event that may trigger the redemption of the Series C Shares is not solely within the Company’s control, the Series C Shares are classified as mezzanine equity (temporary equity) in the Company’s condensed consolidated balance sheets.

11. Stockholders’ Deficit

Common Stock

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.

During the six months ended June 30, 2023, the Company received $2.8 million from the exercise of outstanding warrants with an exercise price between $0.153 and $0.85, of which $1.2 million was received in December 2022 as investor advances. The Company issued approximately 12.3 million shares of common stock upon these warrant exercises.

During the six months ended June 30, 2023, certain options and warrants holders elected to exercise some of their options and warrants pursuant to cashless exercise formulas. The Company issued approximately 9.9 million shares of common stock upon exercise of 10.6 million warrants and 1.5 million options at exercise prices between $0.20 and $0.35.

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.

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 £4.4 million ($5.6 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. The milestone incentives involve a combination of cash and stock and are not paid until they are achieved and earned, as described in Note 9.

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. 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 $329,000), 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 $251,000). On November 4, 2021, the Company received a letter from the local tax authorities asking for additional late fees of €513,000 (now approximately $558,000) 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, 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 $241,000). On July 27, 2022, the Company was informed that the German Tax Authorities were prepared to waive €135,000 (approximately $147,000) 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 $410,000) as well as for all unpaid taxes as of June 30, 2023. 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 June 2023, the Company entered into certain non-dilutive funding agreements with multiple investors, pursuant to which the Company received funding of $4.1 million related to a gain contingency. These agreements are accounted for under ASC 470 and are recognized as contingent payment obligations on the Company’s condensed consolidated balance sheet. The Company’s payment obligations only apply when such are received by the Company.

In July 2023, approximately 24,000 Series C Shares with a book value of $0.4 million were converted into 0.6 million common shares in accordance with their terms at a ratio of 1:25.

Between July and August 2, 2023, the Company issued approximately 4.9 million shares of common stock to a lender in lieu of cash payments on $2.5 million of outstanding debt, including $0.1 million interest. The Company also issued 0.3 million shares of common stock to that lender to extinguish $0.2 million Share liability.

On July 11, 2023, the Company entered into a one-year convertible note (the “July Convertible Note”) with an individual investor (the “Holder”) with an aggregate principal amount of $0.5 million. The Company received $0.5 million cash from the July Convertible Note. The July Convertible Note bears interest at 10% per annum, and is convertible into Series C preferred shares at $12.50 per share at the Holder’s sole option. The Series C preferred shares are convertible into common stock 30 days after the debt conversion date. Each Series C preferred share is convertible into 25 shares of common stock.

Between July 1, 2023 and August 9, 2023, the Company received $0.5 million in additional non-dilutive funding 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 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 brain cancer (GBM).

The trial results were presented at a scientific conference in May 2022, and were reported in a peer reviewed publication in JAMA Oncology, 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 in the final stages of preparing an application for regulatory approval of DCVax-L. The Company is working with teams of specialized consultants on preparation of the application package as well as related activities. One of the pre-requisites - obtaining regulatory approval of a Pediatric Investigation Plan (PIP) - was completed during 2022 on an accelerated basis, including regulatory approval to use the same trial design with external controls as was used in the Company’s Phase 3 trial.

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 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 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 optimizing 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.

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 plan to conduct clinical trials of DCVax-L for other types of solid tumor cancers, beyond brain cancer, when resources permit. Our second product, DCVax®-Direct, is designed to treat inoperable solid tumors. A 40-patient Phase I trial has been completed

26

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.

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.

Our critical accounting policies and significant estimates are detailed in our Annual Report on Form 10-K for the year ended December 31, 2022. 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, nonemployees 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. Approximate 141 million warrants to purchase shares of the Company’s common stock were classified as liabilities through January 8, 2023.

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.

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.

27

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.

Three Months Ended June 30, 2023 and 2022

We recognized a net loss of $14.4 million and $29.7 million for the three months ended June 30, 2023 and 2022, respectively.

Research and Development Expense

For the three months ended June 30, 2023 and 2022, research and development expense was $6.2 million and $13.6 million, respectively. The decrease in 2023 was mainly related to the following factors:

We incurred $0.1 million and $9.1 million R&D expense related to one-time milestone activities under the SOW 6 with Advent BioServices for the three months ended June 30, 2023 and 2022, respectively. We completed 9 out of the total 10 one-time milestones as of March 31, 2023, and therefore, we only expensed $0.1 million for the three months ended June 30, 2023 related to the remaining one milestone. During the three months ended June 30, 2022, we expensed $3.8 million (but only paid $0.5 million) for one-time cash milestones and $5.3 million (but only issued 1.5 million shares of common stock at fair value of $1.4 million) for one-time stock-based milestones that we believe are probable to be achieved and hence to become payable during the contract period.  
The stock-based compensation in research and development related to stock options and Flaskworks performance-based awards were reduced by $0.5 million during the three months ended June 30, 2023 compared to the same period in 2022, which was related to less amortization related to previously granted awards.
An increased level of research and development activities in 2023 compared to 2022, which resulted in other R&D expenses increased by approximate $2.0 million.

Table of Contents

General and Administrative Expense

For the three months ended June 30, 2023 and 2022, general and administrative expenses was $7.6 million and $7.9 million, respectively. The decrease in 2023 was mainly related to a decrease of $0.3 million in consulting expense and $0.4 million in travel and conference expenses, which is partly offset by an increase of $0.2 million in stock-based compensation.

Change in Fair Value of Derivatives

We recognized a non-cash gain of $0.1 million and a non-cash loss of $4.3 million for the three months ended June 30, 2023 and 2022, respectively. The non-cash gain in 2023 was primarily due to the decrease of our stock price.

The 2022 loss was primarily due to the extension of the exercise periods of certain warrants and offset by a decrease of stock price as of June 30, 2022 compared to March 31, 2022.

Debt Extinguishment

During the three months ended June 30, 2023, we issued approximately 6.9 million shares of common stock with a fair value of $3.9 million to certain lenders in lieu of cash payments of $3.2 million of debt, including $0.5 million accrued interest. In addition, pursuant to exchange agreements executed with various holders, the Company is required to potentially issue additional common stock (the “Share liability”) if the stock price is less than the price defined in the exchange agreement as of the true-up date. During the three months ended June 30, 2023, we extinguished Share liabilities of $0.4 million and recognized an additional $0.1 million of Share liabilities. We recognized an approximately $0.4 million debt extinguishment loss during the three months ended June 30, 2023 from the debt redemption.

During the three months ended June 30, 2023, we issued approximately 13,000 shares of Series C preferred stock at fair value of $0.2 million to certain lenders in lieu of cash payments of $0.2 million debt, including $25,000 accrued interest. We recognized an approximately $24,000 debt extinguishment loss.

Interest Expense

During the three months ended and June 30, 2023 and 2022, we recorded interest expense of $1.3 million and $1.4 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 gain (loss)

During the three months ended and June 30, 2023 and 2022, we recognized foreign currency transaction gain of $0.7 million and loss of $2.8 million, respectively. The gain during the three months ended June 30, 2023 was due to the weakening of the U.S. dollar relative to the British pound sterling, while the loss during the three months ended March 31, 2022 was due to the strengthening of the U.S. dollar relative to the British pound sterling.

Six Months Ended June 30, 2023 and 2022

We recognized a net loss of $25.1 million and $43.9 million for the six months ended June 30, 2023 and 2022, respectively.

Research and Development Expense

For the six months ended June 30, 2023 and 2022, research and development expense was $13.1 million and $18.5 million, respectively. The decrease in 2023 was mainly related to the followings:

We incurred $1.4 million and $9.1 million R&D expense related to one-time milestone activities under the SOW 6 with Advent BioServices for the six months ended June 30, 2023 and 2022, respectively. Advent had completed 7 out of the total 10 one-time milestones as of December 31, 2022, and majority of the one-time R&D expense was recognized in 2022. Therefore, we only expensed $1.4 million for the six months ended June 30, 2023 related to the remaining 3 milestones. During the six months ended June 30, 2022, we expensed $3.8 million (but only paid $0.5 million) for one-time cash milestones and $5.3 million (but only issued

29

Table of Contents

1.5 million shares of common stock at fair value of $1.4 million) for one-time stock-based milestones that we believe are probable to be achieved and hence to become payable during the contract period.
The stock-based compensation in research and development related to stock options and Flaskworks performance-based awards were reduced by $0.8 million during the six months ended June 30, 2023 compared to the same period in 2022, which was related to less amortization related to previously granted awards.
An increased level of research and development activities in 2023 compared to 2022, which resulted in other R&D expenses increasing by approximately $3.0 million.

General and Administrative Expense

For the six months ended June 30, 2023 and 2022, general and administrative expenses was $14.5 million and $15.8 million, respectively. The decrease in 2023 was mainly related to a decrease of $1.2 million in consulting expense and $0.4 million in travel and conference expenses, which is offset by an increase of $0.1 million in stock-based compensation.

Change in Fair Value of Derivatives

We recognized a non-cash gain of $4.0 million and a non-cash loss of $3.7 million for the six months ended June 30, 2023 and 2022, respectively. The non-cash gain in 2023 was primarily due to the decrease of our stock price.

The 2022 loss was primarily due to the extension of the exercise periods of certain warrants and offset by a decrease of stock price as of June 30, 2022 compared to December 31, 2021.

Debt Extinguishment

During the six months ended June 30, 2023, we issued approximately 15.2 million shares of common stock with a fair value of $9.6 million to certain lenders in lieu of cash payments of $7.4 million of debt, including $0.7 million accrued interest. In addition, pursuant to exchange agreements executed with various holders, the Company is required to potentially issue additional common stock (the “Share liability”) if the stock price is less than the price defined in the exchange agreement as of the true-up date. During the six months ended June 30, 2023, we extinguished Share liabilities of $1.1 million and recognized an additional $0.6 million of Share liabilities. We recognized an approximately $1.8 million debt extinguishment loss during the six months ended June 30, 2023 from the debt redemption.

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

Interest Expense

During the six months ended and June 30, 2023 and 2022, we recorded interest expense of $2.3 million and $3.3 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 gain (loss)

During the three months ended and June 30, 2023 and 2022, we recognized foreign currency transaction gain of $1.6 million and loss of $3.7 million, respectively. The gain during the six months ended June 30, 2023 was due to the weakening of the U.S. dollar relative to the British pound sterling, while the loss during the six months ended June 30, 2022 was due to the strengthening 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

30

Table of Contents

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.

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.

Cash Flow

Operating Activities

During the six months ended June 30, 2023 and 2022, net cash outflows from operations were approximately $22.8 million and $27.8 million, respectively. The decrease in cash used in operating activities was primarily attributable to a decrease of $4.2 million in payments to external service providers and a decrease of $0.8 million interest payments to note holders.

Investing Activities

We spent approximately $2.6 million and $0.5 million in cash for the purchase of additional equipment and our build out in Sawston, UK during the six months ended June 30, 2023 and 2022, respectively.

Financing Activities

We received approximately $4.8 million of cash from issuance of 0.3 million shares of Series C convertible preferred stock during the six months ended June 30, 2023.

During the six months ended June 30, 2023, we received approximately $10.0 million in cash proceeds from the issuance of a loan to a commercial lender, and during the six months ended June 30, 2022, we received approximately $0.6 million in cash proceeds from the issuance of multiple loans to individual lenders.  

We received approximately $1.6 million and $9.6 million of cash from the exercise of warrants during the three months ended June 30, 2023 and 2022, respectively.

We received approximately $9.5 million of cash from issuance of 13.1 million shares of common stock during the six months ended June 30, 2022.

We received approximately $1.1 million of cash from issuance of convertible notes to individual lenders during the six months ended June 30, 2023.

We received $4.1 million from issuance of non-dilutive funding agreements during the six months ended June 30, 2023.

We made aggregate debt payments of $0.2 million and $5.3 million during the six months ended June 30, 2023 and 2022, respectively.

We made repayment of $0.1 million of investor advances during the six months ended June 30, 2023.

Other factors affecting our ongoing funding requirements include the number of staff we employ, the number of sites, number of patients and amount of activity in our clinical trial programs, the costs of further product and process development work relating to our DCVax products, the costs of preparations for Phase II trials, the costs of expansion of manufacturing, and unanticipated developments. The extent of resources available to us will determine which programs can move forward and at what pace.

Off-Balance Sheet Arrangements

Since our inception, we have not engaged in any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.

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

31

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 June 30, 2023, 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 June 30, 2023, 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.

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 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 Biotherapeutics Inc. v. Canaccord, et al., No. 1:22-cv-10185-GHW-GWG).  The Company plans 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 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) through its Say on Pay vote, and the director awards are subject to shareholder approval. 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”).

The Company believes these cases are baseless and is vigorously contesting the Derivative Action.On December 30, 2022, shareholders approved the challenged grants to the directors and ratified the challenged awards to the officers. On February 22, 2023, the Company filed a Motion to Dismiss the case. The parties fully briefed the motion in April 2023 and oral argument on the motion is scheduled for September 2023.
