AUTOLUS THERAPEUTICS PLC
Notes to the Unaudited Condensed Consolidated Interim Financial Statements

Note 1. Nature of the Business
Autolus Therapeutics plc (with its subsidiaries, collectively, “Autolus” or the “Company”) is an early commercial-stage biopharmaceutical company developing next-generation programmed T cell therapies for the treatment of cancer and autoimmune diseases. Using its broad suite of proprietary and modular T cell programming technologies, the Company is engineering precisely targeted, controlled and highly active T cell therapies that are designed to better recognize target cells, break down their defense mechanisms and attack and kill these cells. The Company believes its programmed T cell therapies have the potential to be best-in- class and to offer patients substantial benefits over the existing standard of care, including the potential for cure in some patients. On November 8, 2024 Autolus was notified by the United States Food and Drug Administration (the “FDA”) that its biologics license application (“BLA”) was approved, allowing for the marketing of AUCATZYL (obecabtagene autoleucel, also known as obe-cel) in the United States for the treatment of adult patients (18 years and older) with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (“r/r B-ALL”). The commercial launch and first sale of AUCATZYL in the United States occurred in January 2025. The United Kingdom Medicines and Healthcare products Regulatory Agency (“MHRA”) granted AUCATZYL conditional marketing authorization in April 2025, and subject to the National Institute for Health and Care Excellence (“NICE”) recommending National Health Service (“NHS”) funding. Autolus anticipates commercial launch in the United Kingdom in the second half of 2025. In July 2025, the Company was granted marketing approval in the EU by the European Commission for AUCATZYL for the treatment of adult patients (26 years and older) with r/r B-ALL.
Autolus is registered in England and Wales. Its registered office is The MediaWorks, 191 Wood Lane, London, W12 7FP, United Kingdom.
The Company is subject to risks and uncertainties common to companies in the biotechnology industry, including, but not limited to, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations and the ability to secure additional capital to fund operations. The Company’s product candidates currently under development will require significant additional research and development efforts, including preclinical and clinical testing and regulatory approval, prior to commercialization. The Company also expects to incur significant additional costs as it expands its commercialization efforts for AUCATZYL. These efforts will require significant amounts of capital, as well as additional personnel, infrastructure, and compliance capabilities. Even if the Company’s product development efforts for obe-cel and its other product candidates are successful, it is uncertain when, if ever, the Company will become profitable.
The Company is a public limited company incorporated under the laws of England and Wales, and qualifies as a “foreign private issuer,” as such term is defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”), and Rule 3b-4 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and, therefore, is not subject to the same requirements that are imposed upon United States domestic issuers by the Securities and Exchange Commission (the “SEC”). The Company has decided to voluntarily file periodic reports, such as annual reports on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K on United States domestic issuer forms, which are more detailed and extensive in certain respects, and which must be filed more promptly than the forms currently required for foreign private issuers. Although the Company has voluntarily chosen to file periodic reports and current reports on United States domestic issuer forms, the Company will maintain its status as a foreign private issuer and is not subject to certain other requirements imposed on United States domestic issuers including its officers, directors, and principal shareholders are not subject to the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act.

Notes to the Unaudited Condensed Consolidated Interim Financial Statements - Continued
The significant accounting policies used in the preparation of these unaudited condensed consolidated interim financial statements are consistent with those discussed in Note 2, “Summary of Significant Accounting Policies” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the SEC on March 20, 2025 (the “Annual Report”). The information included in these unaudited condensed consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2024, included in the Annual Report.
These condensed consolidated interim financial statements include all adjustments, consisting of normal recurring adjustments, which, in the opinion of management, are necessary to fairly state the Company’s financial position as of June 30, 2025, and the results of its operation for the three-month and six-month period ended June 30, 2025, and cash flows for the six-month period ended June 30, 2025. The interim results and cash flows are not necessarily indicative of results and cash flows that may be expected for the year ending December 31, 2025.
Going Concern
The Company has incurred recurring losses since its inception, including net losses of $47.9 million and $58.3 million for the three months ended June 30, 2025 and 2024, respectively and $118.1 million and $111.0 million for the six months ended June 30, 2025 and 2024, respectively. The Company had an accumulated deficit of $1,217.3 million and $1,099.2 million as of June 30, 2025 and December 31, 2024, respectively. The Company expects to continue to generate operating losses in the foreseeable future. The Company’s inability to raise additional capital as and when needed could have a negative impact on its financial condition and ability to pursue its business strategies. There can be no assurances, however, that the current operating plan will be achieved or that additional funding will be available on terms acceptable to the Company, or at all. The Company expects that its cash and cash equivalents and marketable securities of $123.8 million and $330.5 million, respectively, as of June 30, 2025, will be sufficient to fund the Company’s operations for at least twelve months from the issuance date of these unaudited condensed consolidated interim financial statements and accordingly they have been prepared on a going concern basis. As the Company continues to incur losses, the transition to profitability is dependent upon the successful development, approval and commercialization of its product candidates and achieving a level of revenues adequate to support its cost structure. Even if the Company is successful in its current and future commercialization efforts for obe-cel and even if the Company's planned regulatory submissions for its current or future products are approved, additional funding may be needed before the Company is expected to become profitable.
Use of Estimates
The preparation of condensed consolidated interim financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting periods. Significant estimates and assumptions reflected in these condensed consolidated interim financial statements include, but are not limited to, the accrual for research and development expenses, income taxes, initial fair value of warrants, and present value of liabilities related to future royalties and milestones, net including the related interest expense and cumulative catch-up adjustment, incremental borrowing rates related to the Companys leased properties, allocation of transaction price using the relative standalone selling price relating to license revenue and the estimated expected rebate and chargeback percentage for revenue deductions related to product revenue, net. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Actual results could differ from those estimates.
Expected rebate and chargeback percentage for product revenue deductions
Since approval of AUCATZYL in November 2024, Autolus has a short history of actual rebate claims or chargebacks, and such information may have limited predictive value. The Company uses the expected value method to estimate expected rebate and chargeback percentages for revenue deductions, which considers the likelihood of a rebate or chargeback being applicable to sales. The proportion of sales subject to a rebate or chargeback is inherently uncertain and estimates are based on internal assumptions, which may change as it develops more product revenue experience, and third-party data, which we assess for reliability and relevance.
The Company is subject to state government Medicaid and TriCare programs and other qualifying federal and state programs in the United States requiring rebates to be paid to participating state and local government entities, depending on the eligibility and circumstances of patients treated with AUCATZYL.

Notes to the Unaudited Condensed Consolidated Interim Financial Statements - Continued
The Company's wholly-owned subsidiary in the United States also participates in programs with government entities, which are the US Department of Defense (the “DoD”), the US Department of Veterans Affairs (the “VA”) and TriCare, and other parties, including covered entities under the 340B Drug Pricing Program (the “340B Program”), whereby pricing on AUCATZYL is extended below list price to participating entities, including Authorized Treatment Centers (“ATCs”). These entities are entitled to purchase AUCATZYL at the lower program price by charging the Company the difference between their acquisition cost and the lower program price. Estimating expected rebate and chargeback percentages for revenue deductions is judgmental due to the time delay between the date of the sale to ATCs and the subsequent dates on which we are able to determine actual amounts of chargebacks and rebates.
The Company forms estimates of the 340B Program, the DoD and the VA chargeback deductions by analyzing sell-through data relating to the hospital mix of onward sales made by ATCs. For Medicaid and other rebates, the Company forms estimates based on information obtained from claims received, historical and estimated payor mix, setting of care, discount rates and other industry data, and external health coverage statistics. Judgment is applied to consider the relevance and reliability of information used to make these estimates.
Total accrued product revenue deductions for the six months ended June 30, 2025 of $2.1 million were related to critical estimates subject to significant estimation uncertainty and judgment, as described above. The Company recorded $1.6 million within accrued expenses and other current liabilities in the unaudited condensed consolidated balance sheet related to these deductions as of June 30, 2025.
Segment Information
The Company’s chief operating decision maker (the “CODM”), its Chief Executive Officer and Executive Team members, manages the Company’s operations on an integrated basis for the purpose of appropriately allocating resources. When evaluating the Company’s financial performance, the CODM reviews total revenue, total expenses and expenses by function and makes decisions using this information on a global basis. The Company and the CODM view the Company’s operations and manage its business as a single operating and reportable segment, which is the business of developing and commercializing CAR T therapies.
Inventories, Net
The Company commences capitalization of inventory once regulatory approval for a product candidate is received. Prior to regulatory approval, the Company expenses all such costs as incurred as research and development expenses. The Company capitalizes material costs, labor and applicable overheads that are incurred in the production of its commercial product. Inventory that can be used for either clinical, research or commercial purposes is classified initially as inventory. Inventory that is subsequently used in clinical trials or research activities is expensed once it has been used for research and development purposes.
On November 8, 2024, the Company received FDA approval for AUCATZYL and commenced capitalization of inventory for AUCATZYL from such date.
Inventories are measured at the lower of cost or net realizable value, with cost determined using a weighted average method for different components of inventory. The Company reviews the recoverability of inventory at each reporting period to determine any changes to net realizable value arising from excess, slow-moving or obsolete inventory. If net realizable value is lower than cost, the inventory will be written down to net realizable value and an impairment charge will be recognized in cost of sales.
Consumables consist of materials used primarily in the quality acceptance testing of AUCATZYL and cleaning of the Company’s commercial manufacturing facility and research and development facilities.
Raw materials inventory consists of completed materials purchased directly from third party suppliers.
Work in progress inventory consists of materials manufactured either by the Company or at contract manufacturing organizations that are either partially manufactured or fully manufactured but are pending quality acceptance release.
Finished goods are completed and quality approved drug products that are either awaiting shipment or are in-transit and therefore have not been delivered to the ATCs.

Product revenue, net
Product revenue
The Company accounts for its revenues pursuant to the provisions of ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). The Company has identified a single performance obligation which is satisfied upon delivery of the product to the authorized treatment centers. However, the performance obligation is constrained by the right of return/credit eligibility. The Company recognizes revenue from product sales upon administration to the patient, when the customers’ ability to either cancel the order or request a refund has ceased. Revenue from product sales that are invoiced and constrained is recorded as deferred revenue on the balance sheet.
On April 1, 2025, the Centers for Medicare and Medicaid Services (“CMS”) included AUCATZYL in their published Healthcare Common Procedure Coding System (“HCPCS”) coding determinations and Hospital Outpatient Prospective Payment System (“OPPS”) payment rates, formalizing reimbursement for patients on government programs. The CMS policy splits the therapeutic dose of AUCATZYL into two administrations for coding and billing purposes. As a result, effective from the second quarter of 2025, the Company recognizes 50% of revenue upon administration of the first dose and the remaining 50% of revenue upon administration of the second dose, when the customers’ ability to either cancel the order or request a refund has ceased for each respective dose.
Product revenue, net of gross-to-net deductions, are recognized only to the extent that a significant reversal in the amount of cumulative revenue recognized is not probable of occurring when the uncertainty associated with gross-to-net deductions is subsequently resolved. Product revenue is recognized net of estimated rebates and chargebacks, patient travel assistance and patient co-pay assistance deductions. These deductions to product revenue are referred to as gross-to-net deductions and are estimated and recorded in the period in which the related product revenue occurs.
Gross-to-net deductions
Rebates and chargebacks
Rebates and chargebacks are based on contractual arrangements or statutory requirements and include amounts due to payors and healthcare providers under various programs. These amounts may vary by payor and individual plans. Providers qualified under certain programs can purchase the Company's products through the Company's third-party logistics partner at a discount. The Company's third-party logistics partner then charge the discount back to the Company.
Rebates and chargebacks are estimated primarily based on product sales, including pricing, historical and estimated payor mix, setting of care and discount rates, among other inputs, which require significant estimates and judgment. The Company assesses and updates its estimates each reporting period to reflect actual claims and other current information.
The Company's wholly-owned subsidiary in the United States also participates in programs with government entities, the most significant of which are the DOD, the VA and TriCare, and other parties, including covered entities under the 340B Program, whereby pricing on products is extended below list price to participating entities. These entities purchase products at the lower program price then charge the Company the difference between their acquisition cost and the lower program price. Accounts receivable is reduced for the estimated amount of unprocessed charge-back claims attributable to a sale.
The Company's wholly-owned subsidiary in the United States further participates in state government Medicaid programs and the Tricare program requiring discounts and rebates to participating government entities. All discounts and rebates provided through these programs are included in the Company's Medicaid and Tricare rebate accrual. The estimated amount of unpaid or unbilled rebates are to be recognized and presented as a liability.
Patient Travel, Lodging and Meal Assistance
Travel, lodging, and meal assistance represents financial assistance to qualified patients and their caregiver by reimbursing certain travel, lodging, and meal expenses incurred during their treatment. The Company expenses the actual expenses made during the period and accrues the estimated unreported or unrecorded expenses at period end.
Patient Co-Pay Assistance
Co-pay assistance represents financial assistance to qualified patients, assisting them with cost sharing obligations for the Company's product based on benefit design structure required by insurance. The Company's accrual for copay is based on an estimate of claims and the cost per claim that the Company expects to receive associated with qualified patients that exist at each reporting period.

Foreign Currency Translation
The reporting currency of the Company is U.S. dollars. The Company has determined that its functional currency of the ultimate parent company, Autolus Therapeutics plc, is British Pound Sterling. The functional currency of each subsidiary’s operations is the applicable local currency. Monetary assets and liabilities denominated in currencies other than the Company’s functional currency are translated into the functional currency at rates of exchange prevailing at the balance sheet dates. Non-monetary assets and liabilities denominated in foreign currencies are translated into the functional currency at the exchange rates prevailing at the date of the transaction. Translation adjustments are not included in determining net income (loss) but are included in foreign currency translation to other comprehensive loss, a component of shareholders’ equity.
The Company recorded foreign exchange gain of $1.5 million and foreign exchange gain of $1.2 million for the three months ended June 30, 2025 and 2024, respectively, and foreign exchange gain of $2.7 million and foreign exchange losses of $0.5 million for the six months ended June 30, 2025 and 2024, respectively, which are included in foreign exchange gains (losses), net in the unaudited condensed consolidated statements of operations and comprehensive loss.
Recently Issued Accounting Pronouncements
In January 2025, the Financial Accounting Standards Board (the “FASB”) issued the Accounting Standards Update (“ASU”) 2025-01—Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date, to clarify the effective date of ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. FASB clarified that all public business entities should initially adopt the disclosure requirements in the ASU 2024-04 in the first annual reporting period beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. The Company is currently assessing the effect of this ASU on its consolidated financial statements and related disclosures.
In November 2024, the FASB issued ASU 2024-03—Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, to improve the disclosures about entity’s expenses. The amendments apply to all public business entities. The ASU is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027 with early adoption permitted. The Company is currently assessing the effect of this ASU on its consolidated financial statements and related disclosures.
In March 2024, the FASB issued ASU 2024-02—Codification Improvements—Amendments to Remove References to the Concepts Statements, that contains amendments to the Codification that remove references to various FASB Concepts Statements. This effort facilitates Codification updates for technical corrections such as conforming amendments, clarifications to guidance, simplifications to wording or the structure of guidance, and other minor improvements. The amendments are effective for public business entities for fiscal years beginning after December 15, 2024, with early adoption permitted. Early application of the amendments in this ASU is permitted for all entities, for any fiscal year or interim period for which financial statements have not yet been issued (or made available for issuance). If an entity adopts the amendments in an interim period, it must adopt them as of the beginning of the fiscal year that includes that interim period. The Company adopted ASU 2024-02 on January 1, 2025 and will apply ASU 2024-02 prospectively to all new transactions recognized on or after the adoption date. The adoption of ASU 2024-02 did not have material effect on the Company's condensed consolidated financial statements and related disclosures for the three and six months ended June 30, 2025.
In March 2024, the FASB issued ASU 2024-01—Compensation—Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards, to improve GAAP by adding an illustrative example that includes four fact patterns to demonstrate how an entity should apply the scope guidance in paragraph 718-10-15-3 to determine whether a profits interest award should be accounted for in accordance with Topic 718, Compensation—Stock Compensation. For public business entities, the amendments in this ASU are effective for annual periods beginning after December 15, 2024, and interim periods within those annual periods. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. If an entity adopts the amendments in an interim period, it should adopt them as of the beginning of the annual period that includes that interim period. The Company adopted ASU 2024-01 on January 1, 2025. The adoption of ASU 2024-01 did not have material effect on the Company's condensed consolidated financial statements and related disclosures for the three and six months ended June 30, 2025.
In December 2023, the FASB issued ASU 2023-09—Improvements to Income Tax Disclosures. This ASU improves the transparency of income tax disclosure by requiring consistent categories and greater disaggregation of information in the rate reconciliation, and income taxes paid disaggregated by jurisdiction. This guidance is effective for the Company for the year beginning January 1, 2025, with early adoption permitted. The Company does not expect the adoption of ASU 2023-09 to have a material effect on condensed consolidated financial statements and related disclosures for the three and six months ended June 30, 2025.
Unless otherwise discussed, the impact of recently issued standards that are not yet effective are not expected to have a material impact on the Company’s condensed consolidated financial statements and disclosures.

Major customers
The Company did not recognize any license revenue during the three and six months ended June 30, 2025. During the three and six months ended June 30, 2024, 100% of the Company’s license revenues were generated from BioNTech.

License and Option Agreement with BioNTech
On February 6, 2024, the Company concurrently entered into a (i) Securities Purchase Agreement (the “BioNTech Securities Purchase Agreement”), (ii) Registration Rights Agreement, (iii) Letter Agreement and (iv) License and Option Agreement (the “BioNTech License and Option Agreement”), collectively called the “BioNTech Agreements”, with BioNTech.
For further details on the terms and accounting treatment considerations for the BioNTech Agreements, refer to following notes to these interim condensed consolidated financial statements:
Note 2, “Summary of significant accounting policies”
Note 13, “Shareholders’ equity”
Note 15, “Liabilities related to future royalties and milestones, net”
Note 17, “Commitments and contingencies”
As the BioNTech License and Option Agreement has been accounted for as one freestanding financial instrument with various embedded features, including the Binder License and related transfer of know-how, Technology Options, and Product Options, the Company is required to consider if the embedded features are required to be bifurcated from the host contract and therefore accounted for as a separate derivative. The Company concluded the Binder License and related transfer of know-how, Technology Options, and Product Options meet the scope exception set out in ASC 815-10-15-59(d) and therefore not accounted for as derivatives under ASC 815, Derivatives and Hedging (“ASC 815”).
Binder License
The Company applied ASC 606 to account for the Binder License and related know-how as functional intellectual property. The Binder License and related transfer of know-how were not distinct from one another and must be combined as a performance obligation, as BioNTech requires the know-how to derive benefit from the license. Based on these determinations, the Company identified one combined distinct performance obligation at the inception of the BioNTech License and Option Agreement.
The Company further determined the consideration received included in the transaction price at contract inception, is to be allocated to the one combined performance obligation. The Company determined that the performance obligation was recognized at a point-in-time, upon the delivery of the transfer of know-how and Binder License to BioNTech. The Company recognized total license revenue of $10.1 million (net of foreign exchange differences), related to the BioNTech License and Option Agreement during the three months ended March 31, 2024. No license revenue was recognized during the three and six months ended June 30, 2025.
The Company is eligible to receive milestone payments of up to $32.0 million in the aggregate upon the achievement of specified clinical development and regulatory milestones for each Binder Licensed Product that achieves such milestones. The Company is also eligible to receive a low single-digit royalty on net sales of Binder Licensed Products, subject to customary reductions, which are subject to specified limits. The royalty will be increased if BioNTech, its affiliates or sublicensees commercialize a Binder Licensed Product in an indication and country in which the Company or its affiliates or licensees also commercializes a product containing the same binders. Under the BioNTech License and Option Agreement, BioNTech is solely responsible for, and has sole decision-making authority with respect to, at its own expense, the exploitation of Binder Licensed Products. Milestone payments and royalty payments are regarded as variable consideration and will be evaluated under the most likely amount method. Milestone payments and royalty payments were not included in the transaction price, as these amounts were fully constrained as of June 30, 2025 and 2024, respectively.

Notes to the Unaudited Condensed Consolidated Interim Financial Statements - Continued
Technology Options
As the Binder Option and the Activity Enhancement Option, referred to as the “Technology Options”, are outside the scope of ASC 815, the Company considered other relevant accounting guidance to apply to this component of the BioNTech License and Option Agreement. The Company therefore applied ASC 606, considering particularly the accounting guidance related to any options granted to customers to purchase additional goods or services at a future date as this could provide a material right to the customer. A material right is a promise embedded in a current contract that should be accounted for as a separate performance obligation. The Company determined the Technology Options were not offered at a significant and incremental discount. Accordingly, the Technology Options granted to BioNTech do not represent a material right and, therefore, were not a performance obligation at the outset of the arrangement. The Technology Options exercise fee equates to the standalone selling price of the technologies underlying each option and consequently, the transaction price of $10.0 million was not allocated to the Technology Options performance obligation. No Technology Options were exercised during the three and six months ended June 30, 2025 and 2024, respectively.
Product Options
As the option to obtain exclusive rights to co-fund development costs of the Company’s development-stage programs AUTO1/22 and AUTO6NG (“Product Options”) are precluded from being accounted for under ASC 815 due to the scope exception, management considered the terms of the Product Options and concluded that they should be accounted for as a gain contingency under the scope of ASC 450, Contingencies (“ASC 450”). The Product Options, unlike the Technology Options, are 1) still subject to negotiation as to the specific activities to be performed by each party, which will be determined and agreed before the Product Options can be exercised, and 2) have not been exercised upon signature of the BioNTech License and Option Agreement. As a result, Product Options are not accounted for under ASC 606, and no recognition is required under ASC 450, until the Product Options are exercised. No Product Options were exercised during the three and six months ended June 30, 2025 and 2024, respectively. The product option for AUTO1/22 was not exercised and expired on February 8, 2025.

Note 6. Fair Value Measurements
The Company uses valuation approaches that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in the following levels:
• Level 1 — Quoted prices in active markets for identical assets or liabilities.
• Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
• Level 3 — Unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability.
The carrying amounts reported in the balance sheet for cash and cash equivalents, restricted cash, prepaid expenses and other assets, accounts payable and accrued expenses and other liabilities approximate their fair value because of the short-term nature of these instruments.

The Company estimates the fair value of available-for-sale debt securities using actual trade and indicative prices sourced from third-party providers on a daily basis to estimate the fair value. If observable market prices are not available (such as for securities with short maturities and limited second market activity), the securities are priced using a valuation model that maximizes the use of observable inputs, such as market interest rates.
As of June 30, 2025 and December 31, 2024, the Company did not have non-financial assets measured at fair value on a recurring basis. During the three and six months ended June 30, 2025 and the year ended December 31, 2024, there were no transfers between fair value levels.

Obe-cel Product Revenue Interest
Under the BioNTech License and Option Agreement, BioNTech has agreed to financially support the expansion of the clinical development program for, and planned commercialization of obe-cel. In exchange for the grant of rights to future revenues from the sales of obe-cel products, BioNTech made an upfront payment to the Company of $40.0 million. The Company will pay BioNTech a low single-digit percentage of annual net sales of obe-cel products, which may be increased up to a mid-single digit percentage in exchange for milestone payments of up to $100.0 million in the aggregate on achievement of certain regulatory events for specific new indications upon BioNTech's election. The Company has accounted for the Obe-cel Product Revenue Interest as a liability primarily due to the Company’s significant continuing involvement in generating the royalty stream. In February 2024, the Company initially recognized the BioNTech Liability at $38.3 million being the face value less debt issuance costs.
Manufacturing and Commercial Services Agreement
Under the terms of the BioNTech License and Option Agreement, the Company has agreed to grant BioNTech the option to negotiate a joint manufacturing and commercial services agreement pursuant to which the parties may access and leverage each other’s manufacturing and commercial capabilities, in addition to Autolus’ commercial site network and infrastructure, with respect to certain of each parties’ CAR T products, including BioNTech’s product candidate BNT211 (the “Manufacturing and Commercial Services Agreement” or “MCSA”). The MCSA, if entered into, would also grant BioNTech access to the Company’s commercial site network and infrastructure. On August 6, 2025, the MCSA option expired unexercised.
The carrying amount of the Blackstone Collaboration Liability and BioNTech Liability is based on the Company’s estimate of the future royalties to be paid to BioNTech to be received over the life of the arrangement as discounted using an effective interest rate. The excess or deficit of estimated present value of future royalties over the initial carrying amount, is recognized using the cumulative catch-up method within interest expense using the initial effective interest rate. The imputed rate of interest on the unamortized portion of the Blackstone Collaboration Liability and BioNTech Liability was approximately 15.80% and 28.70% as of June 30, 2025, respectively.
On a quarterly basis, the Company assesses the amount and timing of expected royalty using a combination of internal projections and forecasts from external sources. To the extent the present value of such payments is greater or less than its initial estimates or the timing of such payments is materially different than its original estimates, the Company will adjust the amortization of the BioNTech Liability using the cumulative catch-up method.

Under the then-current agreement, the Company would be obligated to make specified payments to Adaptive upon the achievement and receipt of certain regulatory approvals and achievement of commercial milestones in connection with the Company’s use of the Adaptive assay.
In previous periods, the Company has entered into agreements with certain advisory firms. The Company is obligated to make specified payments upon the achievement of certain strategic transactions involving the Company. During the three and six months ended June 30, 2024, the Company paid a fee under these agreements. There were no fees paid or payable to strategic advisory firms during the three and six months ended June 30, 2025.

The Company has estimated the probability of the Company achieving each potential milestone in relation to the agreements with UCLB, Miltenyi and its agreements with certain advisory firms in accordance with ASC 450. The Company considers regulatory approval, commercial milestones and execution of collaboration agreements probable when actually achieved. Furthermore, the Company recognizes expenses for clinical milestones when their achievement is deemed probable. The Company concluded that, as of June 30, 2025, there were no other milestones for which the likelihood of achievement was currently probable.
Capital Commitments
As of June 30, 2025, the Company’s unconditional purchase obligations for capital expenditures totaled $13.0 million and included signed orders for capital equipment and capital expenditures for construction and related expenditures relating to its properties in the United Kingdom and the United States. The Company expects to incur the full amount of these obligations within one year.
Master Supply Commitments
As of June 30, 2025, the Company’s unconditional purchase obligations with Miltenyi Biotec GmbH for reagents and consumables totaled $3.5 million, which the Company expects to incur within one year.
BioNTech Agreements
BioNTech License and Option Agreement - Product Options gain contingency
As the Product Options within the BioNTech License and Option Agreement were an embedded feature within a freestanding financial instrument, the Company assessed if the Product Options should be accounted for as a derivative under ASC 815. However, the Company determined the Product Options met the scope exception for derivative accounting under ASC 815 and therefore should be accounted for a gain contingency under the scope of ASC 450. As of June 30, 2025 and December 31, 2024, the Product Options were not exercised and, therefore, no amounts were recognized.
Refer to Note 15, “Liabilities related to future royalties and milestones, net” for further details about the BioNTech Agreements.
Legal Proceedings
From time to time, the Company may be a party to litigation or subject to claims incident to the ordinary course of business. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors. The Company was not a party to any litigation and did not have contingency reserves established for any liabilities as of June 30, 2025 and December 31, 2024.
Indemnification Agreements
In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnification. The Company’s exposure under these agreements is unknown because they involve claims that may be made against the Company in the future. To date, the Company has not paid any claims or been required to defend any action related to its indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations.
In accordance with the indemnification agreements entered into with relevant individuals in accordance with the Company’s Articles of Association, the Company has indemnification obligations to its directors, officers and members of senior management for certain events or occurrences, subject to certain limits, while they are serving at the Company’s request in such capacity.
There have been no claims to date under these indemnification agreements, and the Company has director and officer insurance that may enable it to recover a portion of any amounts paid for future potential claims.
SME R&D tax credit
In the accounting period to December 2023, based on the relevant tax legislation, the Company met the conditions of the R&D intensive scheme, and therefore submitted its corporate tax return on this basis. This is subject to agreement by the United Kingdom tax authority. The tax authority's non-statutory guidance, includes some expenditure in the calculation of whether a company meets the R&D intensive scheme, which is in conflict with the criteria in the tax legislation. The position is uncertain and the legislation is currently untested in the United Kingdom courts. If the Company's claim is unsuccessful, normal SME relief will be available and there will be a material reduction in the value of the tax credit obtained (18.6% as opposed to 26.97% net benefit). Should the uncertainty be resolved in the Company’s favor, this would result in a gain and would be accounted for as a gain contingency under the scope of ASC 450. This uncertainty only applies to one accounting period.

Note 19. Related Party Transactions
Blackstone Agreements
In November 2021, the Company concurrently entered into the Blackstone Agreements. As of the execution of the Blackstone Agreements, Blackstone became a related party of the Company, as Blackstone became the owner of more than 10% of the Company’s outstanding voting securities. In addition, Blackstone received and exercised its right to nominate one director to the board of directors of the Company and is therefore considered to be one of the principal owners of the Company. As of June 30, 2025, Blackstone holds more than 5% of the Company's outstanding voting securities.

Overview
We are an early commercial-stage biopharmaceutical company developing next-generation programmed T cell therapies for the treatment of cancer and autoimmune diseases. Using our broad suite of proprietary and modular T cell programming technologies, we are engineering precisely targeted, controlled and highly active T cell therapies that are designed to better recognize target cells, break down their defense mechanisms and attack and kill these cells. We believe our programmed T cell therapies have the potential to be best-in-class and to offer patients substantial benefits over the existing standard of care, including the potential for cure in some patients.
Since our inception, we have incurred significant operating losses. For the three months ended June 30, 2025 and 2024, we incurred net losses of $47.9 million and $58.3 million, respectively, and had an accumulated deficit of $1,217.3 million and $1,099.2 million as of June 30, 2025 and December 31, 2024, respectively.
As of June 30, 2025, we had cash and cash equivalents of $123.8 million and marketable securities of $330.5 million. Based on our current clinical development and commercialization plans, we believe our existing cash, cash equivalents and marketable securities will be sufficient to fund our current and planned operating expenses and capital expenditure requirements through at least the next twelve months from the date of issuance of our unaudited condensed consolidated financial statements included in this Quarterly Report. This forecast of cash resources is forward-looking information that involves risks and uncertainties, and the actual amount of our revenues and expenses, which we have based on assumptions that may prove to be wrong and could prove to be significantly higher than we currently anticipate, could vary materially and adversely as a result of a number of factors. Management does not know whether additional financing will be on terms favorable or acceptable to us when needed, if at all. If adequate additional funds are not available when required, or if we are unsuccessful in entering into partnership agreements for further development of our product candidates, management may need to curtail its development efforts and planned operations.

Recent Developments
AUCATZYL launch
We reported Q2 2025 net product sales of $20.9 million.
We have 46 cancer treatment centers fully activated in the United States as of August 12, 2025. Patient access to AUCATZYL continues to increase, with coverage secured for greater than 90% of total United States medical lives.
On April 25, 2025, the UK Medicines and Healthcare products Regulatory Agency (“MHRA”) granted conditional marketing authorization for AUCATZYL for the treatment of adult patients age 18+ with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (“r/r B-ALL”). Following an initial review and in line with prior practice for CAR-T therapies, the National Institute for Health and Care Excellence (“NICE”) issued a preliminary Appraisal Consultation Decision (“ACD”) recommending against funding for AUCATZYL. We plan to respond to NICE’s questions and will continue to work towards a pathway for patient access to therapy in the United Kingdom.
On July 17, 2025, the European Commission (“EC”) granted marketing authorization for AUCATZYL in adult patients (age 26 and older) with r/r B-ALL. Evaluation of potential pricing and feasibility of market entry opportunities in certain EU countries is ongoing; however, at this time, launch in Germany is on hold and we do not anticipate any EU sales of AUCATZYL in 2025 and 2026.
Obe-cel clinical updates:
Obe-cel data in r/r B-ALL
We presented updated long-term data from the FELIX study in adult patients with r/r B-ALL in an oral presentation at the 2025 European Hematology Association (“EHA”) Congress in June. For patients with a response, the updated median duration of response is now 42.5 months. At the updated median follow up of 32.8 months, 38.4% of responders were in ongoing remission without consolidative stem cell therapy or other therapies (versus the previously reported 40% at a median follow-up of 21.5 months). The 24-month probability of Event Free Survival was 43%, and the Overall Survival was 46%, with a further consolidating long-term plateau observed. No new safety signals or Grade ≥3 secondary malignancies were observed at the extended follow-up. These results suggest that obe-cel may be a durable treatment option for some patients with r/r B-ALL.
Obe-cel in lupus nephritis (LN)
Preliminary data from the Phase 1 dose confirmation clinical trial (“CARLYSLE”) in refractory systemic lupus erythematosus (“SLE”) patients were reported on April 23, 2025, and support progressing into a planned Phase 2 pivotal study.
The Company has aligned with the U.S. Food and Drug Administration (the “FDA”) on the Phase 2 trial design and potential registrational path to approval and continues to anticipate dosing the first patient in a Phase 2 clinical trial before the end of 2025.
Data with longer term follow-up from the Phase 1 CARLYSLE clinical trial is targeted for presentation at a medical conference in the second half of 2025.
Obe-cel in progressive multiple sclerosis (MS”)
We plan to advance obe-cel into clinical development in progressive MS. We continue to expect to dose our first patient in a Phase 1 dose escalation clinical trial by year-end 2025.
Early-stage pipeline programs and collaborations:
Our translational programs with University College London (“UCL”) continue to fuel our early-stage pipeline, providing a cost-efficient path to development.
Components of Our Results of Operations
Product revenue, net
We account for our revenues pursuant to the provisions of ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). We have identified a single performance obligation which is satisfied upon delivery of the product to the authorized treatment centers. However, the performance obligation is constrained by the right of return/credit eligibility. We recognize revenue from product sales upon administration to the patient, when the customers’ ability to either cancel the order or request a refund has ceased. Revenue from product sales that are invoiced and constrained is recorded as deferred revenue on the balance sheet.

34

Table of contents
On April 1, 2025, the Centers for Medicare and Medicaid Services (“CMS”) included AUCATZYL in their published Healthcare Common Procedure Coding System (“HCPCS”) coding determinations and Hospital Outpatient Prospective Payment System (“OPPS”) payment rates, formalizing reimbursement for patients on government programs. The CMS policy splits the therapeutic dose of AUCATZYL into two administrations for coding and billing purposes. As a result, effective from the second quarter of 2025, we recognize 50% of revenue upon administration of the first dose and the remaining 50% of revenue upon administration of the second dose, when the customers’ ability to either cancel the order or request a refund has ceased for each respective dose.
Product revenue, net of gross-to-net deductions, are recognized only to the extent that a significant reversal in the amount of cumulative revenue recognized is not probable of occurring when the uncertainty associated with gross-to- net deductions is subsequently resolved. Product revenues are recognized net of estimated rebates and chargebacks, patient travel assistance and patient co-pay assistance deductions. These deductions to product revenue are referred to as gross-to-net deductions and are estimated and recorded in the period in which the related product revenue occur.
Gross-to-net deductions
Rebates and chargebacks
Rebates and chargebacks are based on contractual arrangements or statutory requirements and include amounts due to payors and healthcare providers under various programs. These amounts may vary by payor and individual plans. Providers qualified under certain programs can purchase our products through our third-party logistics partner at a discount. Our third party logistics partner then charges the discount back to us.
Rebates and chargebacks are estimated primarily based on product sales, including pricing, historical and estimated payor mix, setting of care and discount rates, among other inputs, which require significant estimates and judgment. We assess and updates our estimates each reporting period to reflect actual claims and other current information.
Our wholly-owned subsidiary in the United States also participates in programs with government entities, the most significant of which are the US. Department of Defense (the “DoD”) and the US. Department of Veterans Affairs (the “VA”), and other parties, including covered entities under the 340B Drug Pricing Program (the “340B Program”), whereby pricing on products is extended below list price to participating entities. These entities are entitled to purchase AUCATZYL at the lower program price by charging the Company the difference between their acquisition cost and the lower program price. Accounts receivable is reduced for the estimated amount of unprocessed charge-back claims attributable to a sale.
Our wholly-owned subsidiary in the United States further participates in state government Medicaid programs and the Tricare program requiring discounts and rebates to participating government entities. All rebates provided through these programs are included in our Medicaid and Tricare rebate accrual. The estimated amount of unpaid or unbilled rebates are to be recognized and presented as a liability.
Patient Travel, Lodging and Meal Assistance
Travel, lodging, and meal assistance represents financial assistance to qualified patients and their caregiver, reimbursing them for certain travel, lodging, and meal expenses required during their treatment. We expense the actual expenses made during the period and accrue the estimated unreported or unrecorded expenses at period end.
Patient Co-Pay Assistance
Co-pay assistance represents financial assistance to qualified patients, assisting them with cost sharing obligations for our product based on benefit design structure required by insurance. Our accrual for copay is based on an estimate of claims and the cost per claim that we expect to receive associated with qualified patients that exist at each reporting period.
License Revenue
We account for our revenue pursuant to the provisions of ASC 606. As of June 30, 2025, we have entered into various license agreements which included non-refundable upfront license fees, options for future commercial licenses, payments based upon achievement of clinical development and regulatory objectives, payments based upon achievement of certain levels of product sales, and royalties on licensed product sales.
In determining the appropriate amount of revenue to be recognized in relation to each license agreement, we perform the following steps: (i) identify the promised goods or services in the contract; (ii) determine whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measure of the transaction price, including the constraint on variable consideration; (iv) allocate the transaction price to the performance obligations based on estimated selling prices; and (v) recognize of revenue when (or as) we satisfy each performance obligation.

35

Table of contents
License Fees and Multiple Element Arrangements
If a license to our intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, we recognize revenues from non-refundable, upfront fees allocated to the license at such time as the license is transferred to the licensee and the licensee is able to use, and benefit from the license. For licenses that are bundled with other promises, we utilize judgment to assess the nature of the combined performance obligations to determine whether the combined performance obligations are satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, upfront fees. We evaluate the measure of progress at each reporting period and, if necessary, adjust the measure of performance and related revenue recognition.
Appropriate methods of measuring progress include output methods and input methods. In determining the appropriate method for measuring progress, we consider the nature of service that we promise to transfer to the customer. When we decide on a method of measurement, we will apply that single method of measuring progress for each performance obligation satisfied over time and will apply that method consistently to similar performance obligations and in similar circumstances.
Customer Options
If an arrangement is determined to contain customer options that allow the customer to acquire additional goods or services, the goods and services underlying the customer options that are not determined to be material rights are not considered to be performance obligations at the outset of the arrangement, as they are contingent upon option exercise. We evaluate the customer options for material rights, or options to acquire additional goods or services for free or at a discount. If the customer options are determined to represent a material right, the material right is recognized as a separate performance obligation at the outset of the arrangement. We allocate the transaction price to material rights based on the relative standalone selling price, which is determined based on any identified discount and the probability that the customer will exercise the option. Amounts allocated to a material right are not recognized as revenue until, at the earliest, the option is exercised.
Contingent Research Milestone Payments
ASC 606 constrains the amount of variable consideration included in the transaction price in that either all, or a portion, of an amount of variable consideration should be included in the transaction price. The variable consideration amount should be included only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The assessment of whether variable consideration should be constrained is largely a qualitative one that has two elements: the likelihood of a change in estimate, and the magnitude thereof. Variable consideration is not constrained if the potential reversal of cumulative revenue recognized is not significant, for example.
If the consideration in a contract includes a variable amount, we will estimate the amount of consideration in exchange for transfer of promised goods or services. The consideration also can vary if our entitlement to the consideration is contingent on the occurrence or non-occurrence of a future event. We consider contingent research milestone payments to fall under the scope of variable consideration, which should be estimated for revenue recognition purposes at the inception of the contract and reassessed ongoing at the end of each reporting period.
We assess whether contingent research milestones should be considered variable consideration that should be constrained and thus not part of the transaction price. This includes an assessment of the probability that all or some of the milestone revenue could be reversed when the uncertainty around whether or not the achievement of each milestone is resolved, and the amount of reversal could be significant.
U.S. GAAP provides factors to consider when assessing whether variable consideration should be constrained. All of the factors should be considered, and no factor is determinative. We consider all relevant factors.
Royalty Revenue
For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, we recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).

36

Table of contents
Cost of Sales
Cost of sales represents production costs including raw materials, employee-related expenses, including salaries, related benefits, travel and share-based compensation expense for employees engaged in commercial manufacturing functions, external manufacturing costs including outsourced professional expenses services, allocated facilities costs, depreciation and other expenses, royalties payable to third-parties and other costs incurred in bringing inventories to their location and condition prior to sale. Cost of sales also includes the cost of all commercial product delivered to authorized treatment centers, including product delivered but not yet recognized as revenue, which is captured as deferred revenue, any cancelled orders, and product related to the patient access program. Cost of sales may also include costs related to excess or obsolete inventory adjustment charges and amortization expense of intangible assets.
Cost of sales for a newly launched product does not include the full cost of manufacturing until the initial pre-launch raw materials inventory is depleted. Thus, the cost of sales as a percentage of net sales of AUCATZYL for the three and six months ended June 30, 2025 was affected by use of the initial pre-launch raw materials inventory, which was previously expensed as research and development expense, and is referred to as zero cost inventories. We estimate our cost of sales as a percentage of net product revenue and will continue to be positively impacted as we sell product which includes some raw material inventory that was previously expensed prior to the FDA approval.
Research and Development Expenses
Research and development expenses, net (“R&D”) consist of costs incurred in connection with the research and development of our product candidates, which are partially offset by research and development tax credits, including tax credits arising from the U.K. small and medium enterprise (“SME”) regime and research and development expenditure credit (“RDEC”) regime provided by His Majesty's Revenue and Customs (“HMRC”). We expense research and development costs as incurred. These expenses include:
expenses incurred under agreements with CROs, as well as investigative sites and consultants that conduct our clinical trials, preclinical studies and other scientific development services;
manufacturing scale-up expenses and the cost of acquiring and manufacturing preclinical and clinical trial materials;
employee-related expenses, including salaries, related benefits, travel and share-based compensation expense for employees engaged in research and development functions;
expenses incurred for outsourced professional scientific development services;
costs for laboratory materials and supplies used to support our research activities;
allocated facilities costs, depreciation and other expenses, which include rent and utilities; and
upfront, milestone and management fees for maintaining licenses under our third-party licensing agreements.
We recognize external development costs based on an evaluation of the progress to completion of specific tasks using information provided to us by our service providers.
Our direct research and development expenses are tracked on a program-by-program basis for our product candidates and consist primarily of external costs, such as fees paid to outside consultants and CROs in connection with our preclinical development, manufacturing and clinical development activities. Our direct research and development expenses by program also include fees incurred under license agreements. We do not allocate employee costs or facility expenses, including depreciation or other indirect costs, to specific programs because these costs are deployed across multiple programs and, as such, are not separately classified. We use internal resources primarily to oversee research and development as well as for managing our preclinical development, process development, manufacturing and clinical development activities.
Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. As a result, we expect that our research and development expenses will increase substantially over the next few years as we increase personnel costs, initiate and conduct additional clinical trials and prepare regulatory filings related to our product candidates. We also expect to incur additional expenses related to milestone, royalty payments and maintenance fees payable to third parties with whom we have entered into license agreements to acquire the rights related to our product candidates.
After consultation, we have been advised by HMRC that any sale of our obe-cel CAR T therapy to United Kingdom customers in the future will be considered an exempt supply from a United Kingdom VAT perspective. Consequently, we have assessed and restricted the amount of United Kingdom VAT we have historically reclaimed and will continue to do so in the future. The restriction will be based on the estimated United Kingdom market turnover as a percentage of global turnover. We currently expect revenue from United Kingdom customers to only represent a small proportion of our overall activity. If the proportion of revenue from United Kingdom customers increases this would further restrict the amount of United Kingdom input VAT recovered. Included in research and development expenses is historical irrecoverable input VAT previously claimed on research and development expenses and subsequently reversed.

Table of contents
The successful development and commercialization of our product candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the clinical development of any of our product candidates or when, if ever, material net cash inflows may commence from sales of any of our product candidates. This uncertainty is due to the numerous risks and uncertainties associated with development and commercialization activities, including the uncertainty of:
the scope, progress, outcome and costs of our clinical trials and other research and development activities, including establishing an appropriate safety profile with IND-directed studies;
successful patient enrollment in, and the initiation and completion of, clinical trials;
the timing, receipt and terms of any marketing approvals from applicable regulatory authorities;
establishing commercial manufacturing capabilities or making arrangements with third-party manufacturers;
development and timely delivery of commercial-grade drug formulations that can be used in our clinical trials and for commercial manufacturing;
obtaining, maintaining, defending and enforcing patent claims and other intellectual property rights;
significant and changing government regulation;
launching commercial sales of our product candidates, if and when approved, whether alone or in collaboration with others;
maintaining a continued acceptable safety profile of the product candidates following approval; and
significant competition and rapidly changing technologies within the biopharmaceutical industry.
We may never succeed in achieving regulatory approval for any of our product candidates other than AUCATZYL. We may obtain unexpected results from our clinical trials. We may elect to discontinue, delay or modify clinical trials of some product candidates or focus on others. Any changes in the outcome of any of these variables with respect to the development of our product candidates in clinical development could mean a significant change in the costs and timing associated with the development of these product candidates. For example, if the European Medicines Agency (“EMA”), the FDA, or another regulatory authority were to delay our planned start of clinical trials or require us to conduct clinical trials or other testing beyond those that we currently expect or if we experience significant delays in enrollment in any of our planned clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development of that product candidate. Commercialization of our product candidates will take several years and millions of dollars in development costs.
U.K. Research and Development Tax Credits
Research and development expenditure is presented net of reimbursements from reimbursable tax and expenditure credits from the United Kingdom government. As a company that carries out extensive research and development activities, we benefit from the Research and Development tax incentives provided by United Kingdom tax legislation. The specific provisions available to claim under vary year on year dependent on the criteria met.
The benefits from United Kingdom research and development tax credits are recognized in the statements of operations and comprehensive loss as a reduction of research and development expenses and represents the sum of the research and development tax credits recoverable in the United Kingdom.
The SME program has been particularly beneficial to us as under such program the trading losses that arise from our qualifying R&D activities can be surrendered for a cash rebate of up to 33.35% of qualifying expenditure incurred prior to April 1, 2023 and decreasing to 18.6% after April 1, 2023. The United Kingdom government enacted changes to the SME regime effective from April 1, 2023 which included the introduction of a new rate for R&D intensive companies of 27%. Qualifying expenditures largely comprise of employment costs for research staff, consumables, outsourced contract research organization costs and utilities costs incurred as part of research projects for which we do not receive income. A large proportion of costs relate to our pipeline research, clinical trials management and manufacturing development activities, all of which are being carried out by our subsidiary Autolus Limited, are eligible for inclusion within these tax credit cash rebate claims.
Under the RDEC program, the headline rate for qualifying R&D expenditure is 20% and can generate cash rebates of up to 15% on qualifying R&D expenditure.
Amendments to the current SME and RDEC programs contained in the Finance Act 2024 (unless limited exceptions apply) introduce (i) restrictions on the tax relief that can be claimed for expenditure incurred on sub-contracted R&D activities or externally provided workers, where such activities are not carried out in the United Kingdom or such workers are not subject to United Kingdom payroll taxes, and (ii) merge the SME and RDEC programs into a single scheme which would generate net cash benefit of up to 15% of the qualifying expenditure for profit making companies and up to 16.2% for loss making companies. These changes take effect from periods commencing after April 1, 2024.

Table of contents
In the accounting period ending December 31, 2025, we will not qualify for relief under the SME program, based on size criteria concerning employee headcount, turnover and gross assets. However, we may make a claim under the merged RDEC regime, as detailed above.
Selling, General and Administrative Expenses
Selling, general and administrative expenses consist primarily of salaries, related benefits, travel and share-based compensation expense for personnel in executive, finance, legal and other administrative functions. Selling, general and administrative expenses also include allocated facility-related costs, patent filing and prosecution costs and professional fees for marketing, insurance, legal, consulting, accounting and audit services. Included in selling, general and administrative expenses is historical irrecoverable input VAT previously claimed on selling, general and administrative expenses and subsequently reversed.
We anticipate that our selling, general and administrative expenses will increase in the future as we increase our headcount to support the planned development of our product candidates. We anticipate an increase in salaries and related benefits as a result of our preparation for commercial operations, especially as it relates to the sales and marketing of AUCATZYL and our other product candidates.
We have experienced, and expect to continue to experience, increased expense with being a public company, including increased accounting, audit, legal, regulatory and compliance costs associated with maintaining compliance with Nasdaq listing rules and the SEC requirements, director and officer insurance premiums, as well as higher investor and public relations costs. Additionally, should we fail to maintain our status as a foreign private issuer, we would expect to incur increased expenses to remain compliant with the applicable SEC and Nasdaq requirements.
Other income, net
Other income, net consist primarily of sublease income and gains or losses arising from the termination of leases.
Foreign Exchange Gains (Losses), Net
Foreign exchange gains (losses), net primarily consist of foreign currency transaction gains and losses arising from transactions denominated in foreign currencies.
Interest Income
Interest income primarily relates to interest on cash, cash equivalents and available-for-sale debt securities and is presented net of amortization or accretion of the premium or discount on purchase and sales of the debt securities.
Interest Expense, Net
Interest expense, net consists primarily of interest expense arising from amortization of the liabilities related to future royalties and milestones, pursuant to our collaboration agreements with BXLS V - Autobahn L.P, (“Blackstone”) and BioNTech SE (“BioNTech”), using the effective interest rate method. On a quarterly basis, we assess the expected present value of the future Blackstone and BioNTech payments under the Blackstone Collaboration Agreement and BioNTech Agreements which may be received by us and future royalties and sales milestone payments to Blackstone and BioNTech which may be paid by us. To the extent the amount or timing of such receipts or payments is materially different than our previous estimates we record a cumulative catch-up adjustment to the liabilities related to future royalties and milestones. Adjustments to increase or decrease the carrying amount are recognized as an adjustment to interest expense, net in the period in which the change in estimate occurred.
Income Tax Expenses
We are subject to corporate taxation in the United Kingdom, United States, Germany and Switzerland. Due to the nature of our business, we have generated losses since inception. Our income tax (expense) benefit recognized represents the sum of income tax payable or receivable in the United Kingdom and in the United States.
Un-surrendered United Kingdom losses may be carried forward indefinitely to be offset against future taxable profits, subject to numerous utilization criteria and restrictions. The amount that can be offset each year is limited to £5.0 million plus an incremental 50% of United Kingdom taxable profits. After accounting for tax credits receivable, we had accumulated tax losses for carry forward in the United Kingdom of $545.6 million at December 31, 2024. A valuation allowance has been recognized against our deferred tax asset relating to our United Kingdom losses. We carried a $2.4 million deferred tax asset balance related to the United States entity at June 30, 2025 for which a valuation allowance of $1.8 million was applied. At June 30, 2025, we recorded a full valuation allowance against the net deferred tax asset in the United Kingdom, as the recoverability due to future taxable profits was uncertain.
In the event we generate revenues in the future, we may benefit from the United Kingdom “patent box” regime that allows profits attributable to revenues from patents or patented products to be taxed at an effective rate of 10%.

Product Revenue, Net
During the three months ended June 30, 2025, we generated product revenue, net in the amount of $20.9 million, from the sales of AUCATZYL in the United States. We did not generate any product revenue in the three months ended June 30, 2024, as AUCATZYL was approved by the FDA for commercial use on November 8, 2024.
Cost of Sales
In the three months ended June 30, 2025, we recognized cost of sales of $24.4 million, primarily consisting of salaries and other employment related costs, including share-based compensation expense, for personnel involved in AUCATZYL manufacturing activities, as well as outsourced professional services. These costs also included direct production costs for commercial product manufacturing and allocated facility costs such as maintenance, depreciation, utilities and lease expenses. We did not recognize any cost of sales in the three months ended June 30, 2024, as AUCATZYL was not approved by the FDA for commercial use until November 8, 2024.
Certain manufacturing expenses incurred prior to AUCATZYL receiving FDA approval were classified as research and development expenses, resulting in zero cost inventory. If cost of sales included previously expensed inventories, the total cost of sales with these manufacturing costs included for the three months ended June 30, 2025, would have increased by approximately $1.9 million.

Research and development expenses decreased by $9.2 million to $27.4 million for the three months ended June 30, 2025 from $36.6 million for the three months ended June 30, 2024 primarily due to:
a decrease of $7.8 million related to our information technology infrastructure and support for information systems related to an allocation of expense from research and development to cost of sales and inventories related to commercial manufacturing following the FDA approval of AUCATZYL in November 2024;
a decrease of $2.4 million in salaries and other employment related costs including share-based compensation expense, which was mainly driven by the reallocation of employees to commercial manufacturing activities included in cost of sales and inventories; and
a decrease of $1.8 million in clinical trial costs, clinical manufacturing costs, material transportation costs and utilization of raw materials and consumables relating to research and development activities; offset by:
a decrease of $2.8 million in United Kingdom R&D tax credits (resulting in an increase in R&D expense) due to no longer being eligible for the SME scheme and moving to the merged RDEC from January 1, 2025, as well as lower qualifying spend.
Selling, General and Administrative Expenses
Selling, general and administrative expenses increased by $8.4 million to $30.3 million for the three months ended June 30, 2025 from $21.9 million for the three months ended June 30, 2024 primarily due to:
an increase of $5.8 million in salaries and other employment related costs including share-based compensation expenses, which was mainly driven by an increase in the number of employees engaged in selling, general and administrative activities;
an increase of $2.4 million in information technology infrastructure and support for information systems and facility costs relating to the conduct of corporate and commercial operations including increase in space utilized for these activities; and
an increase of $0.2 million in commercial readiness costs including legal and professional fees due to increased commercial readiness activities being undertaken.
Foreign Exchange Gains, Net
Foreign exchange gains, net increased to $1.5 million for the three months ended June 30, 2025 as compared to $1.2 million for the three months ended June 30, 2024 primarily due to gains and losses on a variety of items, including on U.S. dollar monetary assets and liabilities held by our main operating subsidiary in the United Kingdom, as well as our cash and cash equivalents and liabilities related to future royalties and milestones.
Interest Income
Interest income decreased to $5.2 million for the three months ended June 30, 2025, as compared to $9.6 million for the three months ended June 30, 2024. The decrease in interest income of $4.4 million was primarily driven by lower aggregate balances and yield associated with our cash, cash equivalents and marketable securities during the three months ended June 30, 2025 as compared to the three months ended June 30, 2024.

Interest Expense, Net
Interest expense, net decreased to negative $6.8 million for the three months ended June 30, 2025 as compared to $10.2 million for the three months ended June 30, 2024. Interest expense, net decreased by $17.0 million primarily due to changes in the assumptions used in the valuation of the Collaboration Agreement with Blackstone and the BioNTech License and Option Agreement for the three months ended June 30, 2025 compared to the three months ended June 30, 2024. Changes in the assumptions used in the valuation of the Collaboration Agreement with Blackstone and the BioNTech License and Option Agreement resulted in a negative cumulative catch-up adjustment which exceeded the interest expense accrued relating to Blackstone Collaboration Agreement (“Blackstone Collaboration Agreement Liability”) and the BioNTech Obe-cel Product Revenue Interest (“BioNTech Liability”) during the three months ended June 30, 2025 compared to the same period in 2024.
Income Tax Expenses
Income tax expense increased to $0.4 million for the three months ended June 30, 2025 as compared to less than $0.1 million for the three months ended June 30, 2024. Income tax expenses increased by $0.3 million primarily due to an increase in Autolus Inc.'s taxable income due to the recognition of product revenue, net and related intra-group recharges during the three months ended June 30, 2025 compared to the three months ended June 30, 2024.

Liquidity and Capital Resources
As of the date of this Quarterly Report, we have one product, AUCATZYL, approved for commercial sale in the United States, United Kingdom, and the EU, with the first commercial sale occurring in the United States in January 2025. We have not yet begun sales of AUCATZYL in the United Kingdom or the EU. Although we have recorded product revenue for sales of AUCATZYL, we have continued to incur operating losses and generate cumulative negative cash flows from our operations since our inception. We have an accumulated deficit of $1,217.3 million as of June 30, 2025.
We expect to incur significant expenses and operating losses for the foreseeable future as we market and continue commercialization of AUCATZYL and advance our other product candidates through preclinical and clinical development and seek regulatory approval and pursue commercialization of any additional approved products. As a result, we will need significant additional capital to fund our operations until such time as we can generate significant revenue from sales of AUCATZYL or other products for which we may obtain regulatory approval.
We have funded our operations to date primarily with proceeds from product revenue, government grants, sales of our equity securities, through public offerings and pursuant to our at-the-equity market facility, through United Kingdom research and development tax credits and receipts from the SME and RDEC schemes, out-licensing arrangements and strategic collaboration and financing agreements. From our inception in 2014 through June 30, 2025, we have generated an aggregate of $1.7 billion from these capital sources.
As of June 30, 2025, we had cash and cash equivalents of $123.8 million and available-for-sale debt securities of $330.5 million.

Funding Requirements
We expect our expenses to increase substantially in connection with our ongoing activities, particularly as we begin to market and sell AUCATZYL, operate our new commercial manufacturing facility and advance the preclinical activities and clinical trials of our other product candidates. Our expenses will increase as we:
establish and expand our sales, marketing and distribution infrastructure in connection with commercializing AUCATZYL and other product candidates for which we may obtain marketing approval and intend to commercialize on our own or jointly;
seek regulatory approvals for any other product candidates that successfully complete preclinical and clinical trials;
hire additional manufacturing, clinical, medical and development personnel;
expand our infrastructure and facilities to accommodate our growing employee base; and
maintain, expand and protect our intellectual property portfolio.
Our primary uses of capital are compensation and related expenses, clinical costs, external research and development services, laboratory and related supplies, legal and other regulatory expenses, manufacturing and selling AUCATZYL, and administrative and overhead costs. Our future funding requirements will be heavily determined by the resources needed to support the development of our product candidates and commercialization of AUCATZYL. We also expect to incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution, depending on where we choose to commercialize. We may also require additional capital to pursue in-licenses or acquisitions of other product candidates.
Based on our current clinical development and commercialization plans, we believe our existing cash and cash equivalents of $123.8 million and marketable securities of $330.5 million as of June 30, 2025, will enable us to fund our current and planned operating expenses and capital expenditure requirements for at least twelve months from the date of issuance of this Quarterly Report. We have based these estimates on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we expect. If we receive regulatory approval for our other product candidates, we expect to incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution, depending on where we choose to commercialize. We may also require additional capital to pursue in-licenses or acquisitions of other product candidates.
Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical product candidates, we are unable to estimate the exact amount of our working capital requirements. Our future funding requirements will depend on and could increase significantly as a result of many factors, including:
our ability to continue to execute our commercialization strategies for AUCATZYL and, if approved, any of our other product candidates for which we may receive regulatory approval;
the scope, progress, outcome and costs of our clinical trials and other research and development activities;
the costs, timing, receipt and terms of any marketing approvals from applicable regulatory authorities;
the costs of future activities, including product sales, medical affairs, marketing, manufacturing and distribution, for AUCATZYL or any of our product candidates for which we receive marketing approval;
the revenue, if any, received from commercial sale of AUCATZYL or our other product candidates, should any receive marketing approval;
the costs and timing of hiring new employees to support our continued growth;
the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims; and
the extent to which we in-license or acquire additional product candidates or technologies.
Until such time, if ever, that we can generate product revenue sufficient to achieve profitability, we expect to finance our cash needs through a combination of public or private equity offerings, reimbursable United Kingdom research and development tax credits and receipts from the SME and RDEC schemes, out-licensing agreements, or strategic collaboration agreements. To the extent that we raise additional capital through the sale of equity, the ownership interest of existing shareholders will be diluted. If we raise additional funds through other third-party funding, collaborations agreements, strategic alliances, out-licensing agreements or marketing and distribution arrangements, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market products or product candidates that we would otherwise prefer to develop and market ourselves.

Critical Accounting Policies and Significant Judgments and Estimates
Our management's discussion and analysis of our financial condition and results of operations is based on our unaudited condensed consolidated interim financial statements, which we have prepared in accordance with U.S. GAAP. The preparation of our unaudited condensed consolidated financial statements and related disclosures requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, costs and expenses, and the disclosure of contingent assets and liabilities in our unaudited condensed consolidated interim financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.
Below we have included an update to our significant judgments and accounting estimates from those included in our Annual Report.
Expected rebate and chargeback percentage for product revenue deductions
Since approval of AUCATZYL in the United States in November 2024, we have a short history of actual rebate claims or chargebacks, and such information may have limited predictive value. We use the expected value method to estimate expected rebate and chargeback percentages for revenue deductions, which considers the likelihood of a rebate or chargeback being applicable to sales. The proportion of sales subject to a rebate or chargeback is inherently uncertain and estimates are based on internal assumptions, which may change as we develop more product experience, and third-party data, which we assess for reliability and relevance.
We are subject to state government Medicaid and Tricare programs and other qualifying federal and state programs in the United States requiring rebates to be paid to participating state and local government entities, depending on the eligibility and circumstances of patients treated with AUCATZYL.
Our wholly-owned subsidiary in the US also participates in programs with government entities, the most significant of which are the DoD and the VA, and other parties, including covered entities under the 340B Program, whereby pricing on AUCATZYL is extended below list price to participating entities, including ATCs. These entities are entitled to purchase AUCATZYL at the lower program price by charging the Company the difference between their acquisition cost and the lower program price. Estimating expected rebate and chargeback percentages for revenue deductions is judgmental due to the time delay between the date of the sale to ATCs and the subsequent dates on which we are able to determine actual amounts of chargebacks and rebates.
We form estimates of the 340B Program, the DoD and the VA chargeback deductions by analyzing sell-through data relating to the hospital mix of onward sales made by ATCs. For Medicaid and TriCare, we form estimates based on information obtained from claims received, historical and estimated payor mix, setting of care, discount rates and other industry data, and external health coverage statistics. Judgment is applied to consider the relevance and reliability of information used to make these estimates.
Total product revenue deductions for the six months ended June 30, 2025 of $2.1 million were related to critical estimates subject to significant estimation uncertainty and judgment, as described above. We recorded $1.6 million within accrued expenses and other current liabilities in the unaudited condensed consolidated balance sheet related to these deductions as of June 30, 2025.
An increase or decrease of 10% in the portion of sales estimated to be subject to expected rebate and chargeback percentages for amounts payable to governments or government agencies, as described above, would have resulted in a $0.6 million reduction or increase in Product revenue, net reported in the unaudited condensed consolidated statements of operations and comprehensive loss for the six months ended June 30, 2025. We believe our expected values of accruals reported in the unaudited condensed consolidated balance sheet are materially appropriate; however, due to the uncertainties and judgements outlined above, it is possible eventual amounts could significantly differ to these estimates.
Contractual Obligations
As of June 30, 2025, other than disclosed in Notes 15 to 16 to our unaudited condensed consolidated interim financial statements included in this Quarterly Report, there have been no material changes to our contractual obligations and commitments from those described under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report.
Recent Accounting Pronouncements Not Yet Adopted
A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is disclosed in Note 2, “Summary of Significant Accounting Policies,” to our unaudited condensed consolidated interim financial statements included in this Quarterly Report.

Item 3. Quantitative and Qualitative Disclosures about Market Risk
We are exposed to market risks in the ordinary course of our business, which are principally limited to interest rate fluctuations and foreign currency exchange rate fluctuations. We maintain significant amounts of cash that are in excess of federally insured limits in various currencies, placed with one or more financial institutions for varying periods according to expected liquidity requirements.
Interest Rate Risk
Our exposure to interest rate sensitivity is primarily impacted by changes in the underlying United States and United Kingdom bank interest rates. As of June 30, 2025, we had cash and cash equivalents of $123.8 million and marketable securities of $330.5 million, respectively. As of December 31, 2024, we had cash and cash equivalents of $227.4 million and marketable securities of $360.6 million, respectively. Our surplus cash has been invested in interest-bearing savings, money market funds and marketable securities. A hypothetical one percentage point change in interest rates, sustained over the reporting period would have resulted in a $1.2 million increase in interest income on our unaudited condensed consolidated statements of operations and comprehensive loss for the three and six months ended June 30, 2025.
As of June 30, 2025 the Blackstone Collaboration Agreement Liability has a fixed effective interest rate and is not subject to any fluctuations due to interest rates. However, the effective interest rate for the BioNTech Liability may be subject to fluctuations due to the discretionary nature of certain contractual payments to us. We have no other debt outstanding that is subject to interest rate variability. The carrying amount of the Blackstone Collaboration Agreement Liability and BioNTech Liability is based on our estimate of the future royalties, milestones to be paid to Blackstone by us and the expected Blackstone Development Payment to be received over the life of the arrangement as discounted using the initial effective interest rate. The excess or deficit of estimated present value of future royalty, milestone payments and the future Blackstone Development Payment received over the carrying amount is recognized as a cumulative catch-up adjustment within interest expense, net using the effective interest rate.
Foreign Currency Exchange Risk
Foreign currency risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in foreign exchange rates. Our exposure to the risk of changes in foreign exchange rates relates primarily to fluctuations in value of foreign currency cash and cash equivalent balances and liabilities relating to future royalties and milestones held by our main operating subsidiary in the United Kingdom, our operating activities in the United States, and outsourced supplier agreements denominated in currencies other than pound sterling. We minimize foreign currency risk by maintaining cash and cash equivalents of each currency at levels sufficient to meet foreseeable expenditure to the extent practical.
As of June 30, 2025, substantially of our cash and cash equivalents were held by one of our United Kingdom subsidiaries, of which approximately 54% were denominated in pound sterling and approximately 44% were denominated in U.S. dollars, with immaterial amounts denominated in euros and Swiss francs. The significant remainder of our cash and cash equivalents are held by our U.S. subsidiary and denominated in U.S. dollars.
We maintain our accounting records in pounds sterling, our functional currency, and present our consolidated financial statements in U.S. dollars for financial reporting purposes. Monetary assets and liabilities denominated in currencies other than the functional currency are translated into the functional currency at rates of exchange prevailing at the balance sheet dates. Non-monetary assets and liabilities denominated in foreign currencies are translated into the functional currency at the exchange rates prevailing at the date of the transaction. Exchange gains or losses arising from foreign currency transactions are included in the determination of net income (loss) for the respective periods. We recorded foreign exchange gains of $1.5 million and $1.2 million for the three months ended June 30, 2025 and 2024, respectively foreign exchange gains of $2.7 million for the six months ended June 30, 2025 and foreign exchange losses of $0.5 million for the six months ended June 30, 2024 which are included in foreign exchange gains (losses), net in the unaudited condensed consolidated statements of operations and comprehensive loss.
Assets and liabilities are translated at the exchange rates at the balance sheet dates and revenue and expenses are translated at the average exchange rates and shareholders’ equity is translated based on historical exchange rates. Translation adjustments are not included in determining net income (loss) but are included in foreign exchange adjustment to accumulated other comprehensive income (loss), a component of shareholders’ equity.
We do not currently engage in currency hedging activities in order to reduce our currency exposure, but we may begin to do so in the future. Instruments that may be used to hedge future risks may include foreign currency forward and swap contracts. These instruments may be used to selectively manage risks, but there can be no assurance that we will be fully protected against material foreign currency fluctuations.

Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
We maintain “disclosure controls and procedures,” as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Securities and Exchange Act of 1934, as amended (“Exchange Act”) is accumulated and communicated to our management, including our principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.
Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e)) under the Exchange Act as of June 30, 2025.
Based on such evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures were effective at June 30, 2025.
Changes in Internal Control over Financial Reporting
No changes in our internal control over financial reporting (as defined in Rules 13a-15(e) and 15d – 15(e)) under the Exchange Act) occurred during the quarter ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
PART II - OTHER INFORMATION
Item 1. Legal Proceedings.
From time to time, we may become involved in legal proceedings arising in the ordinary course of our business. We are not currently a party to any material legal proceedings, and we are not aware of any pending or threatened legal proceeding against us that we believe could have an adverse effect on our business, operating results or financial condition.
Item 1A. Risk Factors.
Our business is subject to numerous risks. You should carefully consider and evaluate each of the following factors as well as the other information in this Quarterly Report on Form 10-Q, including our financial statements, and related notes, the risk factors discussed in our most recent Annual Report on Form 10-K, in evaluating our business and prospects. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently consider immaterial may also impair our business operations. If any of the following risks actually occur, our business and financial results could be harmed. In that case, the trading price our ADSs could decline. You should also consider the more detailed description of our business contained in our Annual Report on Form 10-K.
Our products and product candidates are subject to government price controls in certain jurisdictions that may affect our ability to ability to receive adequate coverage and reimbursement for AUCATZYL, which could make it difficult for us to sell AUCATZYL profitably.
The current Trump U.S. presidential administration is pursuing policies to reduce regulations and expenditures across government including at HHS, the FDA, CMS and related agencies. These actions, presently directed by executive orders or memoranda from the Office of Management and Budget, may propose policy changes that create additional uncertainty for our business. These actions and proposals may include, for example, (1) reducing agency workforce; (2) directing program cuts; (3) rescinding a Biden administration executive order tasking the Center for Medicare and Medicaid Innovation, or CMMI, to consider new payment and healthcare models to limit drug spending and eliminating the Biden administration’s executive order that directed HHS to establishing an AI task force and developing a strategic plan; (4) directing HHS and other agencies to lower prescription drug costs for Medicare through a variety of initiatives, including by improving upon the Medicare Drug Price Negotiation Program and establishing Most-Favored-Nation pricing for pharmaceutical products; (5) imposing tariffs of imported pharmaceutical products; (6) directing certain federal agencies to enforce existing law regarding hospital and plan price transparency and by standardizing prices across hospitals and health plans; and (7) increasing regulatory requirements. On April 1, 2025, CMS published Healthcare Common Procedure Coding System (“HCPCS”) application summaries and coding determinations, as well as the Outpatient Prospective Payment System (“OPPS”) Addendum B payment rates. AUCATZYL was included in these CMS publications, formalizing reimbursement for patients on government programs such as Medicare and Medicaid. The CMS policy splits the therapeutic dose of AUCATZYL into two administrations for coding and billing purposes. Because AUCATZYL is administered in two infusions
49

Table of contents
approximately ten days apart, the CMS policy to bill each infusion separately may delay our and our treatment centers’ ability to recognize revenue from a particular treatment. Additionally, in May 2025, NICE issued a preliminary ACD recommending against NHS funding for AUCATZYL in the United Kingdom. A second meeting with NICE is planned in August 2025. Until NICE recommends NHS funding for AUCATZYL, we may not receive adequate coverage and reimbursement for AUCATZYL to support a commercial launch in the United Kingdom, which we currently anticipate in the second half of 2025, subject to NICE recommendation.
Additionally, in the United States and some foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of product candidates, restrict or regulate post approval activities, and affect our ability to profitably sell any products and products candidates for which we obtain marketing approval. For example, on July 4, 2025, the annual reconciliation bill, the "One Big Beautiful Bill Act" (“OBBBA”) was signed into law which, is expected to reduce Medicaid spending and enrollment by implementing work requirements for some beneficiaries, capping state-directed payments, reducing federal funding, and limiting provider taxes used to fund the program. OBBBA also narrows access to ACA marketplace exchange enrollment and declines to extend the ACA enhanced advanced premium tax credits, set to expire in 2025, which, among other provisions in the law, are anticipated to reduce the number of Americans with health insurance.
Market acceptance and sales of AUCATZYL will depend in part on the extent to which adequate reimbursement will be available from third-party payors, including government health administration authorities such as CMS in the United States and NHS in the United Kingdom. Third-party payors in the United States often rely upon Medicare coverage policy and payment limitations in setting their own coverage and reimbursement policies. Patients are unlikely to use our products, and providers are unlikely to prescribe our products, unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our products and their administration, and is provided in a timely manner. Therefore, coverage and adequate reimbursement is critical to new medical product acceptance.
We may not obtain or maintain the benefits associated with orphan drug designation, including market exclusivity or favorable pricing.
Obe-cel in B-ALL received orphan drug designation from the FDA in November 2019 and orphan medicinal product status from the European Commission in March 2022. We may seek orphan drug designation for other indications or product candidates. Even if we were to obtain orphan drug designation for a product candidate, we may not obtain orphan exclusivity and that exclusivity may not effectively protect the drug from the competition of different drugs for the same condition, which could be approved during the exclusivity period. Additionally, after an orphan drug is approved, the FDA could subsequently approve another application for the same drug for the same indication if the FDA concludes that the later drug is shown to be safer, more effective or makes a major contribution to patient care.
Orphan drug exclusive marketing rights may be lost if the FDA or European Commission (on the basis of the opinion of the EMA) later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition. In the EU, alongside applying for marketing authorization, the applicant must submit a report to European Medicine Agency's Committee for Orphan Medicinal Products (“COMP”) demonstrating that the criteria for orphan designation are still met; if they are not, the medicine loses its orphan status. An applicant can choose to withdraw their application for orphan designation in the EU at any point before the COMP adopts an opinion. The failure to obtain an orphan drug designation for any product candidates we may develop, the inability to maintain that designation for the duration of the applicable period, or the inability to obtain or maintain orphan drug exclusivity could reduce our ability to make sufficient sales of the applicable product candidate to balance our expenses incurred to develop it, which would have a negative impact on our operational results and financial condition. For example, based on feedback from the COMP and the results of the latest COMP assessment, in June 2025, we voluntarily withdrew obe-cel from the EU register of orphan medicinal products. Following a thorough evaluation, we have determined not to proceed with the launch of AUCATZYL in Europe in the near term, in part due to the difficulty of achieving a commercially viable price in the absence of orphan drug designation.
International trade policies, including tariffs, sanctions and trade barriers may adversely affect our business, financial condition, results of operations and prospects.
We operate in a global economy, and our business depends on a global supply chain for the development, manufacturing, and distribution of our pharmaceutical products, and for the advancement of our preclinical and clinical development programs. There is inherent risk, based on the complex relationships among the U.S. and the countries in which we conduct our business, that political, diplomatic, and national security factors can lead to global trade restrictions and changes in trade policies and export regulations that may adversely affect our business and operations. The current international trade and regulatory environment is subject to significant ongoing uncertainty. We source significant quantities of active pharmaceutical ingredients (“API”), precursor chemicals, and specialized equipment from international suppliers, with substantial reliance on foreign manufacturers. In addition, we manufacture all of our commercial supplies of AUCATZYL and clinical supplies of our other product candidates in the U.K. Tariff policies, particularly those affecting pharmaceutical products, could materially increase our costs and reduce our profitability, including as a result of our inability to adjust pricing in formulary-based markets. Recent and potential future changes in international trade policies,
50

Table of contents
particularly regarding pharmaceutical-specific tariffs, present material risks to our operations and financial performance. Even if our own products are not directly subject to tariffs, the administration of a complex, rapidly changing tariff scheme by limited government personnel at the various U.S. ports of entry may prove challenging, and may create delays in our provision of commercial or clinical supply.
Recent policy discussions have included potential targeted tariffs or other trade measures specifically aimed at pharmaceutical products and ingredients as part of broader healthcare cost control or national security initiatives. Unlike consumer goods, pharmaceuticals face unique regulatory constraints that make rapid supply chain adjustments particularly difficult and costly. Should the current tariffs hold or additional tariffs be imposed specifically targeting pharmaceutical imports, our production costs could rise significantly, and it would be difficult and costly to qualify alternative sources within another country with a lower tariff rate or within the United States, as developing and qualifying alternative sources typically requires at least 18-24 months and substantial investment and regulatory approvals. Moreover, the dynamic and unpredictable tariff and trade landscape creates substantial uncertainty and significant planning challenges for our operations.
Changes in tariff classifications, country-of-origin requirements, or customs procedures can occur with limited notice. This uncertainty complicates our long-term investment decisions regarding manufacturing facilities, supply chain optimization, and research and development locations.
Unlike many industries, our ability to pass increased costs to customers is limited by the structure of pharmaceutical pricing and reimbursement systems. Many of our products are included in formularies with pricing established through annual or multi-year contracts with commercial, third-party payors and pharmacy benefit managers, and reimbursement methodologies established by government programs, such as Medicare. These arrangements typically include fixed pricing terms that were negotiated prior to the implementation of the recently announced tariffs. As a result, and depending on the timing and scope of the implementation of these tariffs, cost increases due to tariffs may be difficult or impossible to pass through to customers until the next negotiation cycle, which could be up to 36 months away.
Current or future tariffs will also result in increased research and development expenses, including with respect to increased costs associated with APIs, raw materials, laboratory equipment and research materials and components. Trade restrictions could result in delays to our development timelines, either by directly affecting the import of materials necessary for our clinical trials and commercialization efforts, or by creating bottlenecks at the U.S. ports of entry. Increased development costs and extended development timelines could place us at a competitive disadvantage compared to companies operating in regions with more favorable trade relationships and could reduce investor confidence and negatively impact our business, results of operations, financial condition and growth prospects.
The complexity of announced or future tariffs may also increase the risk that we or our customers or suppliers may be subject to civil or criminal enforcement actions in the United States or foreign jurisdictions related to compliance with trade regulations. Foreign governments may also adopt non-tariff measures, such as procurement preferences or informal disincentives to engage with, purchase from or invest in United States entities, which may limit our ability to compete internationally and attract non-U.S. investment, employees, customers and suppliers. Foreign governments may also take other retaliatory actions against the United States entities, such as decreased intellectual property protection, increased enforcement actions, or delays in regulatory approvals, which may result in heightened international legal and operational risks. In addition, the United States and other governments have imposed and may continue to impose additional sanctions, such as trade restrictions or trade barriers, which could restrict us from doing business directly or indirectly in or with certain countries or parties and may impose additional costs and complexity to our business.
Trade disputes, tariffs, restrictions and other political tensions between the United States and other countries may also exacerbate unfavorable macroeconomic conditions including inflationary pressures, foreign exchange volatility, financial market instability, and economic recessions or downturns. The ultimate impact of current or future tariffs and trade restrictions remains uncertain and could materially and adversely affect our business, financial condition, and prospects. While we actively monitor these risks, any prolonged economic downturn or escalation in trade tensions could materially and adversely affect our business, ability to access the capital markets or other financing sources, results of operations, financial condition and prospects. In addition, tariffs and other trade developments have and may continue to heighten the risks related to the other risk factors described in our Annual Report for the fiscal year ended December 31, 2024.

Voluntary Withdrawal of Orphan Drug Designation for obe-cel in the European Union
As previously reported, in March 2022, our product obe-cel received European Commission orphan drug designation. In June 2025, we met with the European Medicines Agency's Committee for Orphan Medicinal Products, which is responsible for assessing continued eligibility for EU orphan drug designation. Following such meeting, in June 2025, we voluntarily withdrew obe-cel from the EU register of orphan medicinal products. In July 2025, following a thorough evaluation of the commercial viability of marketing obe-cel in the European Union without an orphan designation, as well as the challenges associated with the framework of pricing policies for advanced cell therapies within the European Union and the potential impact of proposed most favored nations pricing policies in the United States, we put the launch of obe-cel in Germany on hold. Evaluation of potential pricing and feasibility of market entry opportunities is ongoing.

303197006 v5 Exhibit 10.1 AUTOLUS THERAPEUTICS PLC 2025 EMPLOYEE SHARE PURCHASE PLAN ADOPTED BY THE BOARD OF DIRECTORS: MAY 20, 2025 APPROVED BY THE SHAREHOLDERS: JUNE 26, 2025 1. GENERAL; PURPOSE. (a) The Plan provides a means by which Eligible Employees of the Company and certain Designated Companies may be given an opportunity to purchase Shares. The Plan permits the Company to grant a series of Purchase Rights to Eligible Employees under an Employee Stock Purchase Plan. In addition, the Plan permits the Company to grant a series of Purchase Rights to Eligible Employees that do not meet the requirements of an Employee Stock Purchase Plan. (b) The Plan includes two components: a 423 Component and a Non-423 Component. The Company intends (but makes no undertaking or representation to maintain) the 423 Component to qualify as an Employee Stock Purchase Plan. The provisions of the 423 Component, accordingly, will be construed in a manner that is consistent with the requirements of Section 423 of the Code. In addition, this Plan authorizes grants of Purchase Rights under the Non-423 Component that do not meet the requirements of an Employee Stock Purchase Plan. Except as otherwise provided in the Plan or determined by the Board, the Non-423 Component will operate and be administered in the same manner as the 423 Component. In addition, the Company may make separate Offerings which vary in terms (provided that such terms are not inconsistent with the provisions of the Plan or the requirements of an Employee Stock Purchase Plan to the extent the Offering is made under the 423 Component), and the Company will designate which Designated Company is participating in each separate Offering. (c) The Company, by means of the Plan, seeks to retain the services of Eligible Employees, to secure and retain the services of new Employees and to provide incentives for such persons to exert maximum efforts for the success of the Company and its Related Corporations. 2. ADMINISTRATION. (a) The Board will administer the Plan unless and until the Board delegates administration of the Plan to a Committee or Committees, as provided in Section 2(c). References herein to the Board shall be deemed to refer to the Committee except where context dictates otherwise. (b) The Board will have the power, subject to, and within the limitations of, the express provisions of the Plan: (i) To determine how and when Purchase Rights will be granted and the provisions of each Offering (which need not be identical). (ii) To designate from time to time (A) which Related Corporations of the Company will be eligible to participate in the Plan as Designated 423 Companies, (B) which Related Corporations or Affiliates will be eligible to participate in the Plan as Designated Non-423 Companies, (C) which Affiliates or Related Corporations may be excluded from participation in the Plan, and (D) which Designated Companies will participate in each separate Offering (to the extent that the Company makes separate Offerings).


 
303197006 v5 2 (iii) To construe and interpret the Plan and Purchase Rights, and to establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent it deems necessary or expedient to make the Plan fully effective. (iv) To settle all controversies regarding the Plan and Purchase Rights granted under the Plan. (v) To suspend or terminate the Plan at any time as provided in Section 11(b). (vi) To amend the Plan at any time as provided in Section 11(b). (vii) Generally, to exercise such powers and to perform such acts as it deems necessary or expedient to promote the best interests of the Company and its Related Corporations and to carry out the intent that the Plan be treated as an Employee Stock Purchase Plan with respect to the 423 Component. (viii) To adopt such rules, procedures and sub-plans as are necessary or appropriate to permit or facilitate participation in the Plan by, or take advantage of specific tax treatment for Purchase Rights or similar awards granted to, Employees who are foreign nationals or employed or located outside the United States. Without limiting the generality of, and consistent with, the foregoing, the Board specifically is authorized to adopt rules, procedures, and sub-plans regarding, without limitation, eligibility to participate in the Plan, the definition of eligible “earnings,” handling and making of Contributions, setting the purchase price of Shares acquired pursuant to Purchase Rights, establishment of bank or trust accounts to hold Contributions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and handling of share issuances, any of which may vary according to applicable requirements, and which, if applicable to a Designated Non-423 Company, do not have to comply with the requirements of Section 423 of the Code. (c) The Board may delegate some or all of the administration of the Plan to a Committee or Committees. If administration is delegated to a Committee, the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including the power to delegate to a subcommittee any of the administrative powers the Committee is authorized to exercise (and references in this Plan and any applicable Offering Document to the Board will thereafter be to the Committee or subcommittee), subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. Further, to the extent not prohibited by Applicable Law, the Board or Committee may, from time to time, delegate some or all of its authority under the Plan to one or more officers of the Company or other persons or groups of persons as it deems necessary, appropriate or advisable under conditions or limitations that it may set at or after the time of the delegation. The Board may retain the authority to concurrently administer the Plan with the Committee (or its delegate) and may, at any time, revest in the Board some or all of the powers previously delegated. Whether or not the Board has delegated administration of the Plan to a Committee (or a delegate of the Committee), the Board will have the final power to determine all questions of policy and expediency that may arise in the administration of the Plan. (d) All determinations, interpretations and constructions made by the Board in good faith will not be subject to review by any person and will be final, binding and conclusive on all persons. 3. SHARES SUBJECT TO THE PLAN. (a) Subject to the provisions of Section 11(a) relating to Capitalization Adjustments, the maximum number of Shares that may be issued under the Plan will not exceed 3,000,000 (three million)


 
303197006 v5 3 Shares. For the avoidance of doubt, up to the maximum number of Shares reserved under this Section 3(a) may be used to satisfy purchases of Shares under the 423 Component and any remaining portion of such maximum number of Shares may be used to satisfy purchases of Shares under the Non-423 Component. (b) If any Purchase Right granted under the Plan terminates without having been exercised in full, the Shares not purchased under such Purchase Right will again become available for issuance under the Plan. (c) The shares purchasable under the Plan will be new Shares, market purchase or treasury shares. 4. GRANT OF PURCHASE RIGHTS; OFFERING. (a) The Board may from time to time grant or provide for the grant of Purchase Rights to Eligible Employees under an Offering (consisting of one or more Purchase Periods) on an Offering Date or Offering Dates selected by the Board. Each Offering will be in such form and will contain such terms and conditions as the Board will deem appropriate, and with respect to the 423 Component, will comply with the requirement of Section 423(b)(5) of the Code that all Employees granted Purchase Rights will have the same rights and privileges. The terms and conditions of an Offering shall be incorporated by reference into the Plan and treated as part of the Plan. The provisions of separate Offerings need not be identical, but each Offering will include (through incorporation of the provisions of this Plan by reference in the document comprising the Offering or otherwise) the period during which the Offering will be effective, which period will not exceed 27 months beginning with the Offering Date, and the substance of the provisions contained in Sections 5 through 7(f), inclusive. (b) If a Participant has more than one Purchase Right outstanding under the Plan, unless such Participant otherwise indicates in forms delivered to the Company or a third party designated by the Company (each, a “Company Designee”): (i) each form will apply to all of such Participant’s Purchase Rights under the Plan, and (ii) a Purchase Right with a lower exercise price (or an earlier-granted Purchase Right, if different Purchase Rights have identical exercise prices) will be exercised to the fullest possible extent before a Purchase Right with a higher exercise price (or a later-granted Purchase Right if different Purchase Rights have identical exercise prices) will be exercised. (c) The Board will have the discretion to structure an Offering so that if the Fair Market Value of a Share on the first Trading Day of a new Purchase Period within that Offering is less than or equal to the Fair Market Value of a Share on the Offering Date for that Offering, then (i) that Offering will terminate immediately as of that first Trading Day, and (ii) the Participants in such terminated Offering will be automatically enrolled in a new Offering beginning on the first Trading Day of such new Purchase Period. 5. ELIGIBILITY. (a) Purchase Rights may be granted only to Employees of the Company or, as the Board may designate in accordance with Section 2(b), to Employees of a Related Corporation or an Affiliate. Except as provided in Section 5(b) or as required by Applicable Law, an Employee will not be eligible to be granted Purchase Rights unless, on the Offering Date, the Employee has been in the employ of the Company, the Related Corporation or the Affiliate, as the case may be, for such continuous period preceding such Offering Date as the Board may (unless prohibited by Applicable Law) require, but in no event will the required period of continuous employment be equal to or greater than two years. In addition, the Board may provide (unless prohibited by Applicable Law) that no Employee will be eligible to be granted Purchase Rights under the Plan unless, on the Offering Date, such Employee’s customary employment with the Company, the Related Corporation or the Affiliate is more than 20 hours per week and more than five months per


 
303197006 v5 4 calendar year or such other criteria as the Board may determine consistent with Section 423 of the Code with respect to the 423 Component. The Board may also exclude (unless prohibited by Applicable Law) from participation in the Plan or any Offering Employees who are “highly compensated employees” (within the meaning of Section 423(b)(4)(D) of the Code) of the Company, a Related Corporation or an Affiliate, or a subset of such highly compensated employees. (b) The Board may provide that each person who, during the course of an Offering, first becomes an Eligible Employee will, on a date or dates specified in the Offering which coincides with the day on which such person becomes an Eligible Employee or which occurs thereafter, receive a Purchase Right under that Offering, which Purchase Right will thereafter be deemed to be a part of that Offering. Such Purchase Right will have the same characteristics as any Purchase Rights originally granted under that Offering, as described herein, except that: (i) the date on which such Purchase Right is granted will be the “Offering Date” of such Purchase Right for all purposes, including determination of the exercise price of such Purchase Right; (ii) the period of the Offering with respect to such Purchase Right will begin on its Offering Date and end coincident with the end of such Offering; and (iii) the Board may provide that if such person first becomes an Eligible Employee within a specified period of time before the end of the Offering, such individual will not receive any Purchase Right under that Offering. (c) No Employee will be eligible for the grant of any Purchase Rights under the 423 Component if, immediately after any such Purchase Rights are granted, such Employee owns securities possessing five percent or more of the total combined voting power or value of all classes of shares of the Company or of any Related Corporation. For purposes of this Section 5(c), the rules of Section 424(d) of the Code will apply in determining the security ownership of any Employee, and securities which such Employee may purchase under all outstanding Purchase Rights and options will be treated as securities owned by such Employee. (d) As specified by Section 423(b)(8) of the Code, an Eligible Employee may be granted Purchase Rights under the 423 Component only if such Purchase Rights, together with any other rights granted under all Employee Stock Purchase Plans of the Company and any Related Corporations, do not permit such Eligible Employee’s rights to purchase securities of the Company or any Related Corporation to accrue at a rate which, when aggregated, exceeds twenty-five thousand U.S. Dollars ($25,000) of Fair Market Value of such securities (determined at the time such rights are granted, and which, with respect to the Plan, will be determined as of their respective Offering Dates) for each calendar year in which such rights are outstanding at any time. (e) Officers of the Company and any Designated Company, if they are otherwise Eligible Employees, will be eligible to participate in Offerings under the Plan. Notwithstanding the foregoing, the Board may (unless prohibited by Applicable Law) provide in an Offering that Employees who are highly compensated Employees within the meaning of Section 423(b)(4)(D) of the Code will not be eligible to participate. (f) Notwithstanding anything in this Section 5 to the contrary, in the case of an Offering under the Non-423 Component, an Eligible Employee (or group of Eligible Employees) may be excluded from participation in the Plan or an Offering if the Board has determined, in its sole discretion, that participation of such Eligible Employee(s) is not advisable or practical for any reason.


 
303197006 v5 5 6. PURCHASE RIGHTS; PURCHASE PRICE. (a) On each Offering Date, each Eligible Employee, pursuant to an Offering made under the Plan, will be granted a Purchase Right to purchase up to that number of Shares purchasable either with a percentage of earnings (as defined by the Board in each Offering) or with a maximum amount (in U.S. Dollars), as designated by the Board, but in either case not exceeding 15% of such Employee’s earnings (as defined by the Board in each Offering) during the period that begins on the Offering Date (or such later date as the Board determines for a particular Offering) and ends on the date stated in the Offering, which date will be no later than the end of the Offering. (b) The Board will establish one or more Purchase Dates during an Offering on which Purchase Rights granted for that Offering will be exercised and Shares will be purchased in accordance with such Offering. (c) In connection with each Offering made under the Plan, the Board may specify (i) a maximum number of Shares that may be purchased by any Participant on any Purchase Date during such Offering, (ii) a maximum aggregate number of Shares that may be purchased by all Participants pursuant to such Offering and/or (iii) a maximum aggregate number of Shares that may be purchased by all Participants on any Purchase Date under the Offering. If the aggregate purchase of Shares issuable upon exercise of Purchase Rights granted under the Offering would exceed any such maximum aggregate number, then, in the absence of any Board action otherwise, a pro rata (based on each Participant’s accumulated Contributions) allocation of the Shares (rounded down to the nearest whole share) available will be made in as nearly a uniform manner as will be practicable and equitable. (d) The purchase price of Shares acquired pursuant to Purchase Rights will be no less than the lesser of: (i) an amount equal to 85% of the Fair Market Value of the Shares on the Offering Date; or (ii) an amount equal to 85% of the Fair Market Value of the Shares on the applicable Purchase Date. 7. PARTICIPATION; WITHDRAWAL; TERMINATION. (a) An Eligible Employee may elect to participate in an Offering and authorize payroll deductions as the means of making Contributions by completing and delivering to the Company or a Company Designee, within the time specified in the Offering, an enrollment form provided by the Company or Company Designee. The enrollment form will specify the amount of Contributions not to exceed the maximum amount specified by the Board. Each Participant’s Contributions will be credited to a bookkeeping account for such Participant under the Plan and will be deposited with the general funds of the Company except where Applicable Law requires that Contributions be deposited with a third party. If permitted in the Offering, a Participant may begin such Contributions with the first payroll occurring on or after the Offering Date (or, in the case of a payroll date that occurs after the end of the prior Offering but before the Offering Date of the next new Offering, Contributions from such payroll will be included in the new Offering). If permitted in the Offering, a Participant may thereafter reduce (including to zero) or increase his or her Contributions. If required under Applicable Law or if specifically provided in the Offering and to the extent permitted by Section 423 of the Code with respect to the 423 Component, in addition to or instead of making Contributions by payroll deductions, a Participant may make Contributions through payment by cash, check or wire transfer prior to a Purchase Date.


 
303197006 v5 6 (b) During an Offering, a Participant may cease making Contributions and withdraw from the Offering by delivering to the Company or a Company Designee a withdrawal form provided by the Company. The Company may impose a deadline before a Purchase Date for withdrawing. Upon such withdrawal, such Participant’s Purchase Right in that Offering will immediately terminate and the Company will distribute as soon as practicable to such Participant all of his or her accumulated but unused Contributions without interest (unless the payment of interest is otherwise required by Applicable Law) and such Participant’s Purchase Right in that Offering shall thereupon terminate. A Participant’s withdrawal from that Offering will have no effect upon his or her eligibility to participate in any other Offerings under the Plan, but such Participant will be required to deliver a new enrollment form to participate in subsequent Offerings. (c) Unless otherwise required by Applicable Law, Purchase Rights granted pursuant to any Offering under the Plan will terminate immediately if the Participant either (i) is no longer an Employee for any reason or for no reason (subject to any post-employment participation period required by Applicable Law) or (ii) is otherwise no longer eligible to participate. The Company will distribute as soon as practicable to such individual all of his or her accumulated but unused Contributions without interest (unless the payment of interest is otherwise required by Applicable Law). (d) Unless otherwise determined by the Board, a Participant whose employment transfers or whose employment terminates with an immediate rehire (with no break in service) by or between the Company and a Designated Company or between Designated Companies will not be treated as having terminated employment for purposes of participating in the Plan or an Offering; however, if a Participant transfers from an Offering under the 423 Component to an Offering under the Non-423 Component, the exercise of the Participant’s Purchase Right will be qualified under the 423 Component only to the extent such exercise complies with Section 423 of the Code. If a Participant transfers from an Offering under the Non-423 Component to an Offering under the 423 Component, the exercise of the Purchase Right will remain non-qualified under the Non-423 Component. The Board may establish different and additional rules governing transfers between separate Offerings within the 423 Component and between Offerings under the 423 Component and Offerings under the Non-423 Component. (e) During a Participant’s lifetime, Purchase Rights will be exercisable only by such Participant. Purchase Rights are not transferable by a Participant, except by will, by the laws of descent and distribution, or, if permitted by the Company, by a beneficiary designation as described in Section 0. (f) Unless otherwise specified in the Offering or as required by Applicable Law, the Company will have no obligation to pay interest on Contributions. 8. EXERCISE OF PURCHASE RIGHTS. (a) On each Purchase Date, each Participant’s accumulated Contributions will be applied to the purchase of Shares, up to the maximum number of Shares permitted by the Plan and the applicable Offering, at the purchase price specified in the Offering. No fractional shares will be issued unless specifically provided for in the Offering. (b) Unless otherwise provided in the Offering, if any amount of accumulated Contributions remains in a Participant’s account after the purchase of Shares and such remaining amount is less than the amount required to purchase one Share on the final Purchase Date of an Offering, then such remaining amount will be held in such Participant’s account for the purchase of Shares under the next Offering under the Plan, unless such Participant withdraws from or is not eligible to participate in such next Offering, in which case such amount will be distributed to such Participant after the final Purchase Date without interest (unless the payment of interest is otherwise required by Applicable Law). If the amount of Contributions


 
303197006 v5 7 remaining in a Participant’s account after the purchase of Shares is at least equal to the amount required to purchase one (1) whole Share on the final Purchase Date of an Offering, then such remaining amount will be distributed in full to such Participant after the final Purchase Date of such Offering without interest (unless otherwise required by Applicable Law). (c) No Purchase Rights may be exercised to any extent unless the Shares to be issued upon such exercise under the Plan are covered by an effective registration statement pursuant to the Securities Act and the Plan is in material compliance with all applicable U.S. federal and state, foreign and other securities, exchange control and other laws applicable to the Plan. If on a Purchase Date the Shares are not so registered or the Plan is not in such compliance, no Purchase Rights will be exercised on such Purchase Date, and, subject to Section 423 of the Code with respect to the 423 Component, the Purchase Date will be delayed until the Shares are subject to such an effective registration statement and the Plan is in material compliance, except that the Purchase Date will in no event be more than 27 months from the Offering Date. If, on the Purchase Date, as delayed to the maximum extent permissible, the Shares are not registered and the Plan is not in material compliance with all Applicable Laws, as determined by the Company in its sole discretion, no Purchase Rights will be exercised and all accumulated but unused Contributions will be distributed to the Participants without interest (unless the payment of interest is otherwise required by Applicable Law). 9. COVENANTS OF THE COMPANY. The Company will seek to obtain from each U.S. federal or state, foreign or other regulatory commission, agency or other Governmental Body having jurisdiction over the Plan such authority as may be required to grant Purchase Rights and issue and sell Shares thereunder unless the Company determines, in its sole discretion, that doing so is not practical or would cause the Company to incur costs that are unreasonable. If, after commercially reasonable efforts, the Company is unable to obtain the authority that counsel for the Company deems necessary for the grant of Purchase Rights or the lawful issuance and sale of Shares under the Plan, and at a commercially reasonable cost, the Company will be relieved from any liability for failure to grant Purchase Rights and/or to issue and sell Shares upon exercise of such Purchase Rights. 10. DESIGNATION OF BENEFICIARY. (a) The Company may, but is not obligated to, permit a Participant to submit a form designating a beneficiary who will receive any Shares and/or Contributions from the Participant’s account under the Plan if the Participant dies before such Shares and/or Contributions are delivered to the Participant. The Company may, but is not obligated to, permit the Participant to change such designation of beneficiary. Any such designation and/or change must be on a form approved by the Company. (b) If a Participant dies, and in the absence of a valid beneficiary designation, the Company will deliver any Shares and/or Contributions to the executor or administrator of the estate of the Participant. If no executor or administrator has been appointed (to the knowledge of the Company), the Company, in its sole discretion, may deliver such Shares and/or Contributions, without interest (unless the payment of interest is otherwise required by Applicable Law), to the Participant’s spouse, dependents or relatives, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 11. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION; CORPORATE TRANSACTIONS. (a) In the event of a Capitalization Adjustment, the Board will appropriately and proportionately adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to


 
303197006 v5 8 Section 3(a), (ii) the class(es) and number of securities subject to, and the purchase price applicable to outstanding Offerings and Purchase Rights, and (iii) the class(es) and number of securities that are the subject of the purchase limits under each ongoing Offering. The Board will make these adjustments, and its determination will be final, binding and conclusive. (b) In the event of a Corporate Transaction, then: (i) any surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) may assume or continue outstanding Purchase Rights or may substitute similar rights (including a right to acquire the same consideration paid to the shareholders in the Corporate Transaction) for outstanding Purchase Rights, or (ii) if any surviving or acquiring corporation (or its parent company) does not assume or continue such Purchase Rights or does not substitute similar rights for such Purchase Rights, then the Participants’ accumulated Contributions will be used to purchase Shares (rounded down to the nearest whole share) within ten business days (or such other period specified by the Board) prior to the Corporate Transaction under the outstanding Purchase Rights, and the Purchase Rights will terminate immediately after such purchase. 12. AMENDMENT, TERMINATION OR SUSPENSION OF THE PLAN. (a) The Board may amend the Plan at any time in any respect the Board deems necessary or advisable. However, except as provided in Section 11(a) relating to Capitalization Adjustments, shareholder approval will be required for any amendment of the Plan for which shareholder approval is required by Applicable Law. (b) The Board may suspend or terminate the Plan at any time. No Purchase Rights may be granted under the Plan while the Plan is suspended or after it is terminated. (c) Any benefits, privileges, entitlements and obligations under any outstanding Purchase Rights granted before an amendment, suspension or termination of the Plan will not be materially impaired by any such amendment, suspension or termination except (i) with the consent of the person to whom such Purchase Rights were granted, (ii) as necessary to facilitate compliance with any laws, listing requirements, or governmental regulations (including, without limitation, the provisions of Section 423 of the Code and the regulations and other interpretive guidance issued thereunder relating to Employee Stock Purchase Plans) including without limitation any such regulations or other guidance that may be issued or amended after the Adoption Date, or (iii) as necessary to obtain or maintain favorable tax, listing, or regulatory treatment. To be clear, the Board may amend outstanding Purchase Rights without a Participant’s consent if such amendment is necessary to ensure that the Purchase Right and/or the Plan complies with the requirements of Section 423 of the Code with respect to the 423 Component or with respect to other Applicable Laws. Notwithstanding anything in the Plan or any Offering Document to the contrary, the Board will be entitled to: (i) establish the exchange ratio applicable to amounts withheld in a currency other than U.S. Dollars; (ii) permit Contributions in excess of the amount designated by a Participant in order to adjust for mistakes in the Company’s processing of properly completed Contribution elections; (iii) establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Shares for each Participant properly correspond with amounts withheld from the Participant’s Contributions; (iv) amend any outstanding Purchase Rights or clarify any ambiguities regarding the terms of any Offering to enable the Purchase Rights to qualify under and/or comply with Section 423 of the Code with respect to the 423 Component; and (v) establish other limitations or procedures as the Board determines in its sole discretion advisable that are consistent with the Plan. The actions of the Board pursuant to this paragraph will not be considered to alter or impair any Purchase Rights granted under an Offering as they are part of the initial terms of each Offering and the Purchase Rights granted under each Offering.


 
303197006 v5 9 13. TAX QUALIFICATION; TAX WITHHOLDING. (a) Although the Company may endeavor to (i) qualify a Purchase Right for special tax treatment under the laws of the United States or jurisdictions outside of the United States or (ii) avoid adverse tax treatment, the Company makes no representation to that effect and expressly disavows any covenant to maintain special or to avoid unfavorable tax treatment, notwithstanding anything to the contrary in this Plan. The Company will be unconstrained in its corporate activities without regard to the potential negative tax impact on Participants. (b) Each Participant will make arrangements, satisfactory to the Company and any applicable Related Corporation, to enable the Company or the Related Corporation to fulfill any withholding obligation for Tax-Related Items. Without limitation to the foregoing, in the Company’s sole discretion and subject to Applicable Law, such withholding obligation may be satisfied in whole or in part by (i) withholding from the Participant’s salary or any other cash payment due to the Participant from the Company or a Related Corporation; (ii) withholding from the proceeds of the sale of Shares acquired under the Plan, either through a voluntary sale or a mandatory sale arranged by the Company; or (iii) any other method deemed acceptable by the Board. The Company shall not be required to issue any Shares under the Plan until such obligations are satisfied. (c) The 423 Component is exempt from the application of Section 409A of the Code, and any ambiguities herein shall be interpreted to so be exempt from Section 409A of the Code. The Non-423 Component is intended to be exempt from the application of Section 409A of the Code under the short- term deferral exception and any ambiguities shall be construed and interpreted in accordance with such intent. In furtherance of the foregoing and notwithstanding any provision in the Plan to the contrary, if the Committee determines that an option granted under the Plan may be subject to Section 409A of the Code or that any provision in the Plan would cause an option under the Plan to be subject to Section 409A, the Committee may amend the terms of the Plan and/or of an outstanding option granted under the Plan, or take such other action the Committee determines is necessary or appropriate, in each case, without the participant’s consent, to exempt any outstanding option or future option that may be granted under the Plan from or to allow any such options to comply with Section 409A of the Code, but only to the extent any such amendments or action by the Committee would not violate Section 409A of the Code. Notwithstanding the foregoing, the Company shall have no liability to a participant or any other party if the option under the Plan that is intended to be exempt from or compliant with Section 409A of the Code is not so exempt or compliant or for any action taken by the Committee with respect thereto. 14. EFFECTIVE DATE OF PLAN. The Plan will become effective on the Effective Date. No Purchase Rights will be exercised unless and until the Plan has been approved by the shareholders of the Company, which approval must be within 12 months before or after the Adoption Date (or if required under Section 12(a) above, materially amended) by the Board. 15. MISCELLANEOUS PROVISIONS. (a) Proceeds from the sale of Shares pursuant to Purchase Rights will constitute general funds of the Company. (b) A Participant will not be deemed to be the holder of, or to have any of the rights of a holder with respect to, Shares subject to Purchase Rights unless and until the Participant’s Shares acquired upon exercise of Purchase Rights are recorded in the books of the Company (or its transfer agent).


 
303197006 v5 10 (c) The Plan and Offering do not constitute an employment contract. Nothing in the Plan or in the Offering will in any way alter the nature (whether at-will or otherwise) of a Participant’s employment or amend a Participant’s employment contract, if applicable, or be deemed to create in any way whatsoever any obligation on the part of any Participant to continue in the employ of the Company or a Related Corporation or an Affiliate, or on the part of the Company, a Related Corporation or an Affiliate to continue the employment of a Participant. (d) The Plan and all Purchase Rights, including any non-contractual obligations arising in connection therewith, will be governed by and interpreted in accordance with the laws of England and Wales, disregarding any jurisdiction’s choice-of-law principles requiring the application of a jurisdiction’s laws other than that of England and Wales and the courts of England and Wales shall have exclusive jurisdiction to hear any dispute. (e) If any particular provision of the Plan is found to be invalid or otherwise unenforceable, such provision will not affect the other provisions of the Plan, but the Plan will be construed in all respects as if such invalid provision were omitted. (f) A person who is not a party to the Purchase Rights shall not have any rights under or in connection with it as a result of the Contracts (Rights of Third Parties) Act 1999 except where such rights arise under any provision of the Plan for any employer or former employer of the Participant which is not a party. This paragraph does not affect any right or remedy of a third party which exists, or is available, apart from the Contracts (Rights of Third Parties) Act 1999. (g) If any provision of the Plan does not comply with Applicable Law, such provision shall be construed in such a manner as to comply with Applicable Law. 16. DEFINITIONS.

(g) “Capitalization Adjustment” means a nonreciprocal transaction between the Company and its shareholders, such as a share dividend, share split, spin-off, rights offering or recapitalization through a large, nonrecurring cash dividend, that affects the number or kind of Shares (or other Company securities) or the price of Shares (or other Company securities) and causes a change in the per share value of the Shares underlying outstanding Purchase Rights.

A Participant may make additional payments into his or her account if specifically provided for in the Offering, and then only if the Participant has not already had the maximum permitted amount withheld during the Offering through payroll deductions and, with respect to the 423 Component, to the extent permitted by Section 423.

However, service solely as a Director, or payment of a fee for such services, will not cause a Director to be considered an “Employee” for purposes of the Plan.

Such Option will lapse at the end of the 409A Exercise Period (or on such earlier date that the relevant exercise period would otherwise end under these rules). 13.5 If a Repaid Amount is insufficient to exercise the Option linked to the relevant Savings Contract in full: (a) the aggregate Exercise Price paid to exercise the Option may not exceed the Repaid Amount; and (b) the number of Shares acquired on exercise of the Option may not exceed the number obtained by dividing the Repaid Amount by the Exercise Price for the Option and, if the result of that division is not a whole number, rounding it down to the nearest whole number. 14. Exercise after Plan-related Employment ends 14.1 An Option Holder who has ceased to hold Plan-related Employment for one of the reasons listed in rule 14.2 may exercise an Option at any time in the period ending on the earliest to occur of: (a) the date falling six months after the date on which the Plan-related Employment ceased; and (b) the date falling six months after the Bonus Date of the Savings Contract linked to that Option. 14.2 Options may be exercised as set out in rule 14.1 if Plan-related Employment ends for one of the following reasons:

Lapse of Options 16.1 Options may not be transferred or assigned or have any charge or other security interest created over them. An Option will lapse if the relevant Option Holder attempts to do any of those things. The transmission of an Option to an Option Holder's personal representatives on the death of the Option Holder will not cause an Option to lapse. 16.2 An Option will lapse on the earliest of the following: (a) any attempted action by the Option Holder falling within rule 16.1; (b) the date falling six months after the Bonus Date of the Savings Contract linked to the Option, if the Option Holder is alive at that time; (c) when the Option Holder's Plan-related Employment ceases, if the Option may not then be exercised after cessation under any part of rule 13 and the Option Holder is alive at that time; (d) unless non-payment arises when the Option may be exercised under rule 14 or rule 15 or when the Option may be exercised or exchanged under rule 19, the seventh occasion on which the Option Holder omits to make a payment under the Savings Contract linked to the Option; (e) unless notice is given when the Option may be exercised under rule 14 or rule 15 or when the Option may be exercised or exchanged under rule 19, the Option Holder giving notice to terminate that Savings Contract; (f) at the end of any period during which the Option may be exercised under rule 14, unless that period ended on the Option Holder's death; (g) if the Option Holder has died: (i) before the Bonus Date of the Savings Contract linked to the relevant Option, the date falling 12 months after the date of death; or (ii) on or within six months after the Bonus Date of the Savings Contract linked to the relevant Option, the date falling 12 months after that Bonus Date; (h) the time specified for the lapse of the Option under rule 19; and (i) the bankruptcy of the Option Holder. 16.3 Where any part of rule 16.2 refers to the end of an exercise period, the end of the period must be determined without reference to rule 13.4, if it applies. 17. Exercise of Options: process 17.1 An Option may be exercised by the Option Holder giving a written exercise notice to the Company, that must:


 
303332810 v3 12 (a) set out the number of Shares over which the Option Holder wishes to exercise the Option. If that number exceeds the number over which the Option may be validly exercised at the time: (i) the Option shall be treated as exercised only in respect of that lesser number; and (ii) any excess amount paid to exercise the Option must be refunded; (b) be made using a form approved by the Board; and (c) if the Company so requires, be accompanied by the relevant Option Certificate. 17.2 An exercise notice must be accompanied by a payment of an amount equal to the Exercise Price multiplied by the number of Shares specified in the notice, that is, or is derived from, the relevant Repaid Amount. If the Savings Contract provider permits, payment may take the form of a valid direction to the Savings Contract provider to repay to the Company the whole amount due to the Option Holder under the Savings Contract linked to the relevant Option. 17.3 Any exercise notice will be invalid to the extent that it is inconsistent with the Option Holder's rights and obligations under these rules and the relevant Option; 17.4 The Company may permit the Option Holder to correct any defect in an exercise notice (but is not obliged to do so). The date of any corrected exercise notice will be the date of the correction. 17.5 Shares must be allotted and issued (or transferred, as appropriate) within 30 days after a valid Option exercise, subject to the other rules of the Plan. 17.6 Except for any rights determined by reference to a date before the date of allotment, Shares allotted and issued in satisfaction of the exercise of an Option will rank equally in all respects with the other shares of the same class in issue at the date of allotment. 17.7 Shares transferred in satisfaction of the exercise of an Option must be transferred free of any lien, charge or other security interest, and with all rights attaching to them, other than any rights determined by reference to a date before the date of transfer. 17.8 If the Shares are listed or traded on any stock exchange, the Company must apply to the appropriate body for any newly issued Shares allotted on exercise of an Option to be listed or admitted to trading on that exchange. 18. Relationship with employment contract 18.1 The rights and obligations of any Option Holder under the terms of the office or employment with any company will not be affected by being an Option Holder. 18.2 The value of any benefit realised under the Plan by Option Holders will not be taken into account in determining any pension or similar entitlements. 18.3 Option Holders and the directors and employees of Constituent Companies and Associated Companies (past and present) have no rights to compensation or damages on account of any loss in respect of the Plan where such loss arises (or is claimed to arise), in whole or in part, from termination of office or employment with any company. This exclusion of liability


 
303332810 v3 13 applies however termination of office or employment is caused and however compensation or damages may be claimed. 18.4 Option Holders and the directors and employees of Constituent Companies and Associated Companies (past and present) have no rights to compensation or damages on account of any loss in respect of the Plan (however the relevant circumstances are caused, and however compensation or damages may be claimed) where such loss arises (or is claimed to arise), in whole or in part, from: (a) any company ceasing to be a Constituent Company; (b) any company ceasing to be an Associated Company; (c) the transfer of any business from a Constituent Company to any person which is neither a Constituent Company nor an Associated Company; (d) any change to invitations made under the Plan, including any variation of their terms or timing, or their complete suspension or termination; (e) the lapse of any Option; (f) any failure by the Board to nominate an Eligible Company to be a Constituent Company; or (g) any failure by the Board to make an invitation to apply for an Option to any person who is not at the relevant time an Eligible Employee, where it is in the Board's discretion to do so. 19. Exercise of Options on takeover or other corporate event 19.1 For the purposes of rule 19 and rule 20, a Relevant Event means: (a) a person (the Controller) obtaining Control of the Company as a result of: (i) making a general offer to acquire the whole of the issued share capital of the Company (except for any capital already held by the Controller or any person connected with the Controller) that is made on a condition such that, if it is satisfied, the person making the offer will have Control of the Company; or (ii) making a general offer to acquire all the shares in the Company (except for any shares already held by the Controller or any person connected with the Controller) that are of the same class as the Shares; or (b) the court sanctioning a compromise or arrangement under section 899 of the Companies Act 2006 that is applicable to or affects: (i) all the ordinary share capital of the Company or all the shares of the same class as the shares to which the Option relates; or (ii) all the shares, or all the shares of that same class, which are held by a class of shareholders identified otherwise than by reference to their employment or directorships or their participation in a Schedule 3 SAYE option scheme; or


 
303332810 v3 14 (c) shareholders becoming bound by a non-UK reorganisation (as defined in paragraph 47A of Schedule 3) that is applicable to or affects: (i) all the ordinary share capital of the Company or all the shares of the same class as the shares to which the Option relates; or (ii) all the shares, or all the shares of that same class, which are held by a class of shareholders identified otherwise than by reference to their employment or directorships or their participation in a Schedule 3 SAYE option scheme; or (d) a person becoming bound or entitled to acquire Shares under sections 979 to 985 of the Companies Act 2006. 19.2 Subject to rule 20, if a Relevant Event occurs, an Option may be exercised: (a) within six months of a Relevant Event occurring under rule 19.1(a), rule 19.1(b), or rule 19.1(c); (b) at any time after a Relevant Event occurring under rule 19.1(d), for as long as that person remains so bound or entitled. The Option shall lapse when it is no longer capable of being exercised under this rule 19.2 or released pursuant to rule 20. 19.3 If, as a result of a change of Control in the circumstances set out below, Shares will no longer satisfy the requirements of Part 4 of Schedule 3, Options may be exercised within the period of 20 days following the change of Control. The circumstances are: (a) a Relevant Event specified in rule 19.1(a); or (b) a change of Control occurs as a result of a Relevant Event specified in rule 19.1(b), rule 19.1(c) or rule 19.1(d)). If an Option is not then exercised, it will lapse on the expiry of 20 days following the change of Control. 19.4 If the Board reasonably expects a Relevant Event to occur, the Board may make arrangements permitting Options to be exercised during a period of 20 days ending with the Relevant Event. If an Option is exercised under this rule 19.4, it will be treated as having been exercised in accordance with rule 19.2. 19.5 If the Board makes arrangements for the exercise of Options under rule 19.4: (a) unless the Board determines otherwise any Option not exercised in accordance with those arrangements will lapse on the date of Relevant Event; and (b) if the Relevant Event does not occur within 20 days of the date of purported exercise, the Option shall be treated as not having been exercised. 19.6 If a Relevant Event takes place in the course of any corporate reconstruction or reorganisation under which the ultimate beneficial ownership of the business of the Group Companies will remain the same, and the company that obtains Control offers to grant New Options (as defined below) in accordance with rule 20.1, then the Board may determine that:


 
303332810 v3 15 (a) Options may not be exercised; and (b) all Old Options shall lapse at the end of the Rollover Period to the extent that they are not released under rule 20.1. 19.7 In this rule 19 (but not rule 20.1), a person (P) will be deemed to have obtained Control of a company if P, and others acting with P, have obtained Control of it together. 19.8 If the Company passes a resolution for voluntary winding up, any Option may be exercised within six months after the resolution is passed, and it will lapse at the end of that period. 19.9 The Board must notify Option Holders of any event that may trigger the exercise of Options under this rule 19 within a reasonable period after the Board becomes aware of it. 20. Rollover of Options 20.1 If as a result of a Relevant Event a company has obtained Control of the Company, each Option Holder may, by agreement with that company (Acquiring Company) within the Rollover Period, release each Option (“Old Option”) for a replacement option (“New Option”) as set out in this rule 20. 20.2 A New Option must: (a) be over shares in the Acquiring Company (or some other company falling within paragraph 39(2)(b) of Schedule 3) that satisfy the requirements of paragraphs 18 to 20 and 22 of Schedule 3; (b) be a right to acquire such number of shares as have, immediately after grant of the New Option, a total Market Value substantially the same as the total Market Value of the Shares subject to the Old Option immediately before its release; (c) have an exercise price per share such that the total price payable on complete exercise of the New Option is substantially the same as the total Exercise Price payable on complete exercise of the Old Option; and (d) be on terms otherwise identical to the Old Option immediately before the Old Option's release. 20.3 For the purposes of this rule 20, “Rollover Period” has the meaning given in paragraph 38(3) of Schedule 3. 20.4 A New Option granted under rule 20.1 will be treated as having been acquired at the same time as the relevant Old Option for all other purposes of the Plan. 20.5 The Plan will be interpreted in relation to any New Options as if references to: (a) the “Company” (except for those in the definitions of Constituent Company and Eligible Company) were references to the Acquiring Company (or to any other company whose shares are subject to the New Options, as the context may require); and (b) the “Shares” were references to the shares subject to the New Options.


 
303332810 v3 16 20.6 The Company will remain the scheme organiser of the Plan (as defined in paragraph 2(2) of Schedule 3) following the release of Options and the grant of New Options under rule 20.1. 20.7 The Acquiring Company must issue (or procure the issue of) an Option Certificate for each New Option as soon as reasonably practical. 21. Variation of share capital 21.1 If there is a variation of the share capital of the Company (whether that variation is a capitalisation issue (other than a scrip dividend), rights issue, consolidation, subdivision or reduction of capital or otherwise), which affects (or may affect) the value of Options, the Board may adjust the number and description of Shares subject to each Option and/or the Exercise Price of each Option in a manner that the Board, in its reasonable opinion, considers to be fair and appropriate. 21.2 An adjustment under rule 21.1 must meet the following requirements: (a) the total Market Value of Shares subject to the Option must be substantially the same immediately after the variation of share capital as immediately before the variation of share capital; (b) the total amount payable on the exercise of any Option immediately after the variation of share capital must be substantially the same as immediately before the variation of share capital; and (c) the Exercise Price for a Share to be newly issued on the exercise of an Option must not be reduced below that Share's nominal value (unless the Board resolves to capitalise, from reserves, an amount equal to the amount by which the total nominal value of the relevant Shares exceeds the total adjusted Exercise Price, and to apply such amount to pay up the relevant Shares in full). 22. Notices 22.1 In this rule 22: (a) “appropriate address” means: (i) in the case of the Company, its registered office; (ii) in the case of an Eligible Employee or Option Holder, their home address; (iii) if the Option Holder has died, and notice of the appointment of personal representatives has been given to the Company, any contact address they have specified in such notice; and (b) “appropriate email address” means: (i) in the case of the Company, the email address of the Company Secretary; (ii) in the case of an Eligible Employee or Option Holder, if they are permitted to receive personal emails at work, their work email address. 22.2 Any notice or other communication given under or in connection with the Plan shall be in writing and shall be:


 
303332810 v3 17 (a) delivered by hand or by pre-paid first-class post or other next working day delivery service at the appropriate address; or (b) sent by email to the appropriate email address; or (c) electronically through the portal established for the purposes of the Plan from time to time. 22.3 Any notice or other communication given under this rule 22 shall be deemed to have been received: (a) if delivered by hand, on signature of a delivery receipt, or at the time the notice is left at the proper address; (b) if sent by pre-paid first-class post or other next working day delivery service, at 9.00 am on the second Business Day after posting, or at the time recorded by the delivery service; and (c) if sent by email, at 9.00 am on the next Business Day after sending; and (d) if sent by electronically through the portal established for the purposes of the Plan from time to time, immediately. 22.4 This rule 22 does not apply to: (a) the service of any notice of exercise pursuant to rule 17.1; and (b) the service of any proceedings or other documents in any legal action or, where applicable, any arbitration or other method of dispute resolution. 23. Administration and amendment 23.1 The Board shall direct the administration of the Plan. 23.2 The Board may amend the Plan from time to time, but: (a) the Board may not amend a Key Feature if the effect would be that the Plan would no longer be a Schedule 3 SAYE option scheme. If the Board amends a Key Feature, the Company shall make a declaration under paragraph 40B of Schedule 3 that the Plan continues to meet the requirements of Parts 2 to 7 of Schedule 3; (b) while Shares are listed on NASDAQ, the Board may not make any amendment to rule 12 without the prior approval of shareholders. 23.3 The cost of establishing and operating the Plan will be borne by the Constituent Companies in proportions determined by the Board. 23.4 The Company must ensure that, in order to satisfy the exercise of all Options, at all times: (a) it has sufficient unissued or treasury Shares available; or (b) arrangements are in place for any third party to transfer issued Shares, to satisfy the exercise of all the Options.


 
303332810 v3 18 23.5 Any decision under the Plan, and whether to consider making such a decision, shall be entirely at the discretion of the Board. 23.6 The Board will determine any question of interpretation and settle any dispute arising under the Plan. In such matters the Board's decision will be final. 23.7 In making any decision or determination, or exercising any discretion under the rules, the Board shall act fairly and reasonably and in good faith. 23.8 The Company has no obligation to notify any Option Holder: (a) if an Option is due to lapse; or (b) when an Option is due to, or has, become exercisable. 23.9 The Company has no obligation to provide Option Holders with copies of any materials sent to the holders of Shares. 24. Governing law and Jurisdiction 24.1 The Plan, including any non-contractual obligations arising in connection therewith, will be governed by and interpreted in accordance with the laws of England and Wales, disregarding any jurisdiction’s choice-of-law principles requiring the application of a jurisdiction’s laws other than that of England and Wales and the courts of England and Wales shall have exclusive jurisdiction to hear any dispute. 25. Third party rights 25.1 A person who is not a party to the Option shall not have any rights under or in connection with it as a result of the Contracts (Rights of Third Parties) Act 1999 except where such rights arise under any provision of the Plan for any employer or former employer of the Option Holder which is not a party. 25.2 Rule 25.1 does not affect any right or remedy of a third party which exists, or is available, apart from that Act. 26. Data privacy 26.1 For the purpose of operating the Plan in the United Kingdom and the European Union, the Company will collect and process information relating to Eligible Employees and Option Holders in accordance with the privacy notice which is provided to each Eligible Employee and Option Holder.
