AUTOLUS THERAPEUTICS PLC

Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1. Nature of the Business

Autolus Therapeutics plc (the “Company”) is a 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 cancer 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 cancer patients substantial benefits over the existing standard of care, including the potential for cure in some patients.

The Company is subject to risks and uncertainties common to early-stage 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. Product candidates currently under development will require significant additional research and development efforts, including preclinical and clinical testing and regulatory approval, prior to commercialization. These efforts require significant amounts of capital, adequate personnel and infrastructure and extensive compliance-reporting capabilities. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will realize revenue from its product sales.

The Company has funded its operations primarily with proceeds from the sale of equity securities through public offerings and sales pursuant to the Company's at-the-market facility, government grants, U.K. research and development tax credits and receipts from the U.K.'s Research and Development Expenditure Credit program ("RDEC"), out-licensing arrangements and strategic collaboration agreements.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include those of the Company and its wholly owned subsidiaries, Autolus Holdings (UK) Limited, Autolus Limited, Autolus Inc. and Autolus GmbH, and have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). All intercompany accounts and transactions have been eliminated upon consolidation. The significant accounting policies used in preparation of these unaudited condensed consolidated financial statements are consistent with those discussed in Note 2, “Summary of Significant Accounting Policies” in the Company’s Annual Report on Form 20-F for the year ended December 31, 2022 as filed with the Securities and Exchange Commission on March 7, 2023 (the “Annual Report”).

In the opinion of management, all adjustments considered necessary to present fairly the results of the interim periods have been included and consist only of normal and recurring adjustments. Certain information and footnote disclosures have been condensed or omitted as permitted under U.S. GAAP. The results for the three and nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the year ending December 31, 2023, any other interim periods, or any future year or period. As such, the information included in these unaudited condensed consolidated 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, 2022, included in the Annual Report.

The Company has incurred recurring losses since its inception, including net losses of $45.8 million and $42.8 million for the three months ended September 30, 2023 and 2022, respectively and $131.2 million and $121.9 million for the nine months ended September 30, 2023 and 2022, respectively. The Company had an accumulated deficit of $801.4 million and $670.2 million as of September 30, 2023 and December 31, 2022, 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. As of the date these unaudited condensed consolidated financial statements are issued, the Company expects that its cash and cash equivalents at September 30, 2023 of $256.4 million will be sufficient to fund the Company’s operations for at least twelve months from the issuance date of these unaudited condensed consolidated financial statements and accordingly they have been prepared on the going concern basis.

Foreign Currency Translation

The reporting currency of the Company is the U.S. dollar. The Company has determined the functional currency of the ultimate parent company, Autolus Therapeutics plc, is Pound Sterling. The functional currency of subsidiary operations is the applicable local currency. 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.

AUTOLUS THERAPEUTICS PLC

Notes to Condensed Consolidated Financial Statements (Unaudited) - Continued

Exchange gains or losses arising from foreign currency transactions are included in the determination of net income (loss) for the respective periods. The Company recorded foreign exchange losses of $1.7 million and $3.8 million for the three months ended September 30, 2023 and 2022, respectively, and foreign exchange losses of $0.4 million and $4.4 million for the nine months ended September 30, 2023 and 2022, respectively, which are included in other (expenses) income, net in the unaudited condensed consolidated statements of operations and comprehensive loss.

Use of Estimates

Lease Term—Impact on Right-of-Use Assets and Lease Liabilities

In September 2021, the Company entered into an arrangement for lease with Forge Life Sciences Nominee, an affiliate of the Reef Group, for the design, construction and lease of the Company's new 70,000 square foot commercial manufacturing facility, referred to as, The Nucleus, in Stevenage, United Kingdom. Under this arrangement, the landlord leased the facility to the Company on agreed terms, upon satisfaction of certain conditions and completion of construction. Since November 2022, the landlord has handed over various portions of the facility to the Company until July 31, 2023 when the landlord and the Company accepted practical completion of The Nucleus. The Company was required to pay a pro-rated license fee for each portion of the facility which the Company has been granted access until execution of the lease agreement. As the landlord provided the Company with access to portions of the facility, the definition of a lease in accordance with ASC 842, was met. The lease term can materially impact the value of the right of use assets and lease liabilities recorded on our balance sheet as required under ASC 842.

On September 19, 2023, the Company entered into a 20 year lease agreement with Forge Life Sciences Nominee for The Nucleus. The Company calculated the lease term for The Nucleus by taking into account, the noncancellable period specified in the agreement together with the periods a license fee was payable by the Company to the landlord for portions of The Nucleus handed over to the Company.

Recent Accounting Pronouncements Not Yet Adopted

There are no new accounting pronouncements that have been issued by the Financial Accounting Standards Board, “FASB”, that are applicable to the Company.

Notes to Condensed Consolidated Financial Statements (Unaudited) - Continued

The Company identified the following material promises relating to the granting of a non-exclusive license for research, development, manufacturing and commercialization activities as well as the initial transfer of know-how and information to Cabaletta. The Company determined the option exercise fee is not offered at a significant and incremental discount. Accordingly, the option granted to Cabaletta does not represent a material right and, therefore, is not a performance obligation at the outset of the arrangement. The Company determined that the granting of the research license and the initial transfer of know-how were not distinct from one another and must be combined as a performance obligation, as Cabaletta requires the know-how to derive benefit from the license. Based on these determinations, the Company identified one distinct performance obligation at the inception of the contract.

The Company further determined that the license fee payable constituted the entirety of the consideration included in the transaction price at contract inception, which was allocated to the one performance obligation. The amount of the transaction price allocated to the performance obligation is recognized as or when the Company satisfies the 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 research license to Cabaletta. No license revenue was recognized related to the Cabaletta Agreement for the three months ended September 30, 2023. The Company recognized total license revenue of $1.2 million, related to the Cabaletta Agreement for the nine months ended September 30, 2023.

Upon execution of the Cabaletta Agreement, the transaction price included only the $1.2 million non-refundable license fee payable to the Company. The Company may receive further payments upon the exercise of the options for licensed targets, the achievement of certain development and sales milestones, as well as royalty payments based on net sales of each product covered by the licensed intellectual property.

Research, Option and License Agreement with an Investee of Syncona Portfolio Limited

The Company entered into a license agreement with an investee of Syncona Portfolio Limited on September 2, 2020. The terms of the agreement include a non-refundable license fee, payments based upon achievement of clinical development and regulatory objectives, and royalties on product sales. During the three and nine months ended September 30, 2023, Company received variable consideration arising from the achievement of a development milestone amounting to $0.35 million. Consequently, the Company recognized license revenue of $0.35 million (net of foreign exchange differences).

Research, Option and License Agreement with Moderna:

On June 22, 2021, the Company entered into a Research, Option and License Agreement (the “Moderna Agreement”) with ModernaTX, Inc. (“Moderna”), pursuant to which the Company granted to Moderna an exclusive research license to perform research and pre-clinical development activities relating to target sequences with respect to certain of the Company’s research targets and products.

During the three and nine months ended September 30, 2022, Moderna exercised its option, pursuant to the terms of the Moderna Agreement, to license the Company’s proprietary binders against an undisclosed immuno-oncology target for the development and commercialization of mRNA therapeutics resulting in the Company recognizing $2.2 million (net of foreign exchange differences).

The future milestones, which represent variable consideration, will be evaluated under the most likely amount method, and were not included in the transaction price, as these amounts were fully constrained as of September 30, 2023. For further details on the terms and accounting treatment considerations for the Moderna Agreement, please refer to Note 3, "Revenue" to the Company's consolidated financial statements contained in Company's Annual Report filed on March 7, 2023.

Note 10. Liability related to future royalties and sales milestones, net

On November 6, 2021, the Company concurrently entered into the following agreements with BXLS V - Autobahn L.P, ("Blackstone"): (i) Strategic Collaboration Agreement (the “Blackstone Collaboration Agreement"), (ii) Securities Purchase Agreement (the “Blackstone Securities Purchase Agreement”), (iii) Warrant Agreement (the “Blackstone Warrant”) and (iv) a Registration Rights Agreement (the “Blackstone Registration Rights Agreement”). The Blackstone Collaboration Agreement, the Blackstone Securities Purchase Agreement, the Blackstone Warrant and the Blackstone Registration Rights Agreement are collectively referred to as the "Blackstone Agreements". The Blackstone Agreements were entered into and in contemplation of one another and, accordingly, the Company assessed the accounting for the Blackstone Agreements in the aggregate. For further details on the terms and accounting treatment considerations for these contracts, please refer to following notes to the Company's consolidated financial statements contained in the Company's Annual Report:

•Note 2, "Summary of significant accounting policies"

•Note 8, “Liability related to future royalties and sales milestones, net”

•Note 9, "Warrants"

•Note 10, "Shareholders' equity"

In November 2021, the upfront payment of $50 million was paid by Blackstone upon execution of the Blackstone Collaboration Agreement. In December 2022, two Blackstone Development Payments were paid by Blackstone of $35 million each as a result of (i) the joint steering committee’s review of the Company’s interim analysis of pivotal FELIX Phase 2 clinical trial of obe-cel in relapsed/refractory (r/r) adult Acute Lymphoblastic Leukemia (ALL) and (ii) achievement of a pre-agreed manufacturing milestone as a result of completion of planned activities demonstrating the performance and qualification of the Company’s obe-cel’s manufacturing process. The remaining $30 million will be payable to the Company on the achievement on certain specified regulatory milestones. The Company considers the achievement of the specified regulatory milestone as probable when actually achieved.

The carrying amount of the Blackstone Collaboration Agreement liability is based on the Company’s estimate of the future royalties and sales milestones to be paid to Blackstone and the Blackstone Development payment to be received over the life of the arrangement as discounted using an effective interest rate. The excess estimated present value of future royalties and sales milestone payments over the initial carrying amount and future Blackstone Development Payments received, is recognized as a 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 Agreement liability was approximately 15.80% as of September 30, 2023 and December 31, 2022, respectively.

On a quarterly basis, the Company assesses the amount and timing of expected royalty and sales milestone payments using a combination of internal projections and forecasts from external sources. To the extent the present value of such payments are 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 Blackstone Collaboration Agreement liability using the catch-up method. During the three and nine months ended September 30, 2023, there have been no changes to the estimates used in the determination of the carrying amount of the Blackstone Collaboration Agreement liability.

AUTOLUS THERAPEUTICS PLC

Notes to Condensed Consolidated Financial Statements (Unaudited) - Continued

There are a number of factors that could materially affect the probability, amount and timing of royalty and sales milestone payments to be made by the Company and Blackstone Development payment to be received from Blackstone, respectively, most of which are not within the Company’s control. The Blackstone Collaboration Agreement liability is recognized using significant unobservable inputs. These inputs are derived using internal management estimates developed based on third party data and reflect management’s judgements, current market conditions surrounding competing products, and forecasts. The significant unobservable inputs include regulatory approvals, estimated patient populations, estimated selling price, estimated sales, estimated peak sales and sales ramp, timing of the expected launch and its impact on the royalties as well as the overall probability of a success.

Changes to the Blackstone Collaboration Agreement liability related to future royalties and sales milestones are as follows:


	Amount in thousands



Balance at December 31, 2021	$	47,016
Proceeds from Blackstone Development Payments received	70,000
Interest expense accrued on liability related to future royalties and sales milestones, net	8,005

During the three months ended September 30, 2023 and 2022 interest expense accrued on liability related to future royalties and sales milestones, net amounted to $5.0 million and $1.8 million, respectively. During the nine months ended September 30, 2023 and 2022 interest expense accrued on liability related to future royalties and sales milestones, net amounted to $14.9 million and $5.4 million, respectively.

11. Leases

The Company leases certain office space, laboratory space, and equipment. At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present.

Operating Leases

In September 2017, the Company executed an arrangement with Cell Therapy Catapult Limited to lease a manufacturing suite at the Cell and Gene Therapy Catapult manufacturing center in Stevenage, United Kingdom for a term through May 2021, at which time the Company had the option to renew or terminate the lease.

In February 2019, the Company entered into a fifteen-year lease for three manufacturing units in Enfield, United Kingdom with option to terminate the lease in February 2029. In addition to base rent, the Company is obligated to pay its proportionate share of building operating expenses and real estate taxes in excess of base year amounts. In March 2021, one of the units was split into two separate units and the Company surrendered one of the units. Upon the surrender, the Company recognized a $0.1 million gain in other (expense) income after recognizing a termination fee of $0.2 million. The Company has no further obligations for the surrendered unit and the right of use asset and lease liability which were recorded for this unit have been written off in the relevant period. The Company subleased two of the three units to third parties with lease terms ranging from October, 2021 to February 2029 and October 2026, respectively. The Company is actively seeking to sublease or assign the lease arrangements relating to the final unit. The Company completed an asset impairment analysis of the right-of-use lease concluding the undiscounted cash flows exceeded the carrying value as of September 30, 2023.

In September 2021, the Company entered into an arrangement for lease with the landlord, Forge Life Sciences Nominee, an affiliate of the Reef Group, for the design, construction and lease of a new 70,000 square foot commercial manufacturing facility in Stevenage, United Kingdom. Under this arrangement, the landlord leased the facility, which will be called The Nucleus, to the Company on agreed terms, upon satisfaction of certain conditions and completion of construction. Since November 2022, the landlord has handed over various portions of the facility to the Company until July 31, 2023 when the landlord and the Company accepted practical completion of The Nucleus. The Company is required to pay a pro-rated license fee for each portion of the facility which the Company has been granted access until the execution of a lease agreement. The Company cumulatively contributed $7.5 million as part as of landlord works and tenant contributions towards the lease as of September 30, 2023 resulting in these payments being taken into account in the determination of the right of use asset for this facility. On July 31, 2023, the landlord and its contractors accepted practical completion of The Nucleus. On September 19, 2023, the Company entered into a 20 year lease agreement with the landlord for The Nucleus. The Company made fit-out costs in other areas of the building and will be required to be removed at the end of the lease term. As a result, as of September 30, 2023, the Company has recognized an estimated Asset Retirement Obligation ("ARO") amounting to $0.1 million.

Overview

We are a 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 nine months ended September 30, 2023 and 2022, we incurred net losses of $131.2 million and $121.9 million, respectively, and had an accumulated deficit of $801.4 million and $670.2 million as of September 30, 2023 and December 31, 2022, respectively.

As of September 30, 2023, we had cash and cash equivalents of $256.4 million. Based on our current clinical development plans, we believe our existing cash and cash equivalents 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.

Components of Our Results of Operations

Grant Income

Grant income consists of proceeds from government research grants used to perform specific research and development activities. We recognize grant income over the period in which we recognize the related costs covered under the terms and conditions of the grant. We have received grants from the U.K. government, which are repayable under certain circumstances, including breach or noncompliance with the terms of the grant. For grants with refund provisions, we review the grant to determine the likelihood of repayment. If the likelihood of repayment of the grant is determined to be remote, then the grant is recognized as grant income. We have concluded that the likelihood of any repayment events included in our current grants is remote.

License Revenue

We account for our revenue pursuant to the provisions of Accounting Standards Codification, or ASC Topic 606, Revenue from Contracts with Customers (“ASC Topic 606”).

We have no products approved for commercial sale and have not generated any revenue from commercial product sales. The total revenue to date has been generated principally from license agreements. As of September 30, 2023, 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 product sales.

In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under our agreements, we perform the following steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated selling prices; and (v) recognition of revenue when (or as) we satisfy each performance obligation.

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 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 the 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 Topic 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 determinate. 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).

Operating Expenses

Research and Development Expenses

Research and development expenses consist of costs incurred in connection with the research and development of our product candidates, which are partially offset by U.K. research and development expenditure tax credits provided by His Majesty’s Revenue & Customs, or HMRC. We expense research and development costs as incurred. These expenses include:

•expenses incurred under agreements with contract research organizations, (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.

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. 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 FDA, the EMA, 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 can take several years and millions of dollars in development costs.

General and Administrative Expenses

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. General and administrative expenses also include allocated facility-related costs, patent filing and prosecution costs and professional fees for marketing, insurance, legal, consulting, and accounting and audit services.

We anticipate that our general and administrative expenses will increase in the future as we increase our headcount to support the planned development of our product candidates. Additionally, if we believe a regulatory approval of one of our product candidates appears likely, we anticipate an increase in payroll and third-party expense as a result of our preparation for commercial operations, especially as it relates to the sales and marketing of our product candidate.

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 SEC requirements, director and officer insurance premiums, as well as higher investor and public relations costs.

Loss on disposal of property and equipment

Loss on disposal of property and equipment primarily consists of losses arising from the disposal of all categories of property and equipment.

Impairment of operating lease right-of-use assets and related property and equipment

Impairment of operating lease right-of-use assets and related property and equipment consists primarily of impairment losses arising from the impairment of leased properties and leasehold improvements that are currently not be utilized by us.

Other expenses, net

Other income, net consists primarily of foreign currency transaction gains and losses, sublease income and gains or losses arising from the termination of leases. Other expense consists primarily of foreign currency transaction losses.

Interest Income

Interest income consists primarily of interest received from banks and money market funds on our cash and cash equivalents balances. We invest funds in a variety of short-term interest-bearing instruments.

Interest Expense

Interest expense consists primarily of non-cash interest expense arising from amortization of the liability related to future royalties and sales milestones, pursuant to our Collaboration Agreement with Blackstone, using the effective interest rate method. On a quarterly basis, we assess the expected present value of the future Blackstone Development payment which may be received by us and future royalties and sales milestone payments to Blackstone 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 liability related to future royalties and sales milestones. The adjustment to the carrying amount is recognized as an adjustment to finance expense in the period in which the change in estimate occurred.

Income Tax Benefit

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 benefit recognized represents the sum of the research and development tax credits recoverable in the United Kingdom and income tax payable in the United States.

As a company that carries out extensive research and development activities, we benefit from the U.K. research and development tax credit regime under the scheme for small or medium-sized enterprises, or SMEs, and also claim a Research and Development Expenditure Credit, or RDEC, to the extent that our projects are grant funded. Under the SME regime, we are able to surrender some of our trading losses that arise from our qualifying research and development activities for a cash rebate of up to 33.35% of such qualifying research and development expenditure. The UK Government recently enacted changes which reduce the potential cash rebate under the SME regime to 18.6% for qualifying expenditure incurred on or after April 1, 2023. Additionally, the U.K Government announced but has not yet enacted further changes to the SME regime which include the introduction of a new rate for R&D intensive companies of 27% (which we currently expect to qualify for) and comes into effect for expenditure incurred after April 1, 2023. We have not accounted for these latest changes in our financial statements as they have not yet been enacted.

The net tax benefit of the RDEC reflected in our unaudited condensed consolidated financial statements was 10.5% for each of the nine months ended September 30, 2023 and 2022. Following recent proposed changes by the UK Government the net tax benefit of the RDEC for qualifying expenditure incurred on or after April 1, 2023 has been increased to 15%. We currently meet the conditions of the SME regime, but also can make claims under the RDEC regime to the extent that our projects are grant funded. We may not be able to continue in the future to qualify as a small or medium-sized enterprise under the SME Program, based on size criteria concerning employee headcount, turnover and gross assets. If we cease to qualify under the SME regime, we may make a claim under the RDEC regime. It should be noted, however, that the types of qualifying expenditure in respect of which we may make claims under the RDEC Program are more restricted than under the SME Program (for example, it may be the case that certain subcontracted costs in respect of which claims may be made under the SME Program do not qualify for relief under the RDEC Program).

Un-surrendered U.K. 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 U.K. of $320.8 million as of December 31, 2022. No deferred tax assets are recognized on our U.K. losses because there is currently no indication that we will make sufficient taxable profits to utilize these tax losses. We carry a $2.6 million deferred tax asset balance related to the U.S. entity. For the nine months ended September 30, 2023, we have recorded a valuation allowance against the net deferred tax asset where the recoverability due to future taxable profits is unknown. On April 1, 2023 the main rate of the U.K. corporation tax was increased to 25% for companies with profits in excess of £250,000, or the small profits rate of 19% for companies with profits of £50,000 or less (with marginal relief from the main rate available to companies with profits between £50,000 and £250,000).

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%.

Value Added Tax, or VAT, is broadly charged on all taxable supplies of goods and services by VAT-registered businesses. Under current rates, an amount of 20% of the value, as determined for VAT purposes, of the goods or services supplied is added to all sales invoices and is payable to HMRC. Similarly, VAT paid on purchase invoices is generally reclaimable from HMRC.

Research and development expenses decreased by $0.4 million to $37.2 million for the three months ended September 30, 2023 from $37.6 million for the three months ended September 30, 2022 primarily due to:

•a decrease of $4.8 million in clinical costs and manufacturing costs primarily relating to our obe-cel clinical product candidate,

•a decrease of $0.5 million in depreciation and amortization related to property, plant and equipment and intangible assets,

•a decrease of $0.5 million in professional consulting and legal fees in relation to our research and development activities,

•a decrease of $0.2 million related to general office expenses, offset by:

•an increase of $3.2 million in facilities costs related to our new manufacturing facility, The Nucleus, in Stevenage, United Kingdom as well as increases in costs related to maintaining our current leased properties,

•an increase of $1.7 million in salaries and other employment related costs including share-based compensation expense, which was mainly driven by an increase in the number of employees engaged in research and development activities, and

•an increase of $0.7 million related to information technology infrastructure and support for information systems related to our new manufacturing facility.

General and Administrative Expenses

General and administrative expenses increased by $2.4 million to $10.6 million for the three months ended September 30, 2023 from $8.2 million for the three months ended September 30, 2022 primarily due to:

•an increase of $2.0 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 general and administrative activities,

•an increase of $0.4 million related to information technology infrastructure and support for information systems related to the conduct of corporate and commercial operations,

•an increase of $0.3 million in facility costs due to the increase in space utilized for general and administrative activities and related to general office expense,

•an increase of $0.1 million in depreciation and amortization related to property and equipment and intangible assets, offset by:

•a decrease of $0.2 million primarily related to a reduction in directors' and officers' liability insurance premiums, legal and professional fees, and

•a decrease of $0.2 million in costs related to commercial-stage readiness activities.

Impairment of operating lease right-of-use assets and related property and equipment

For the three months ended September 30, 2023, we recognized an impairment loss on operating lease right-of-use assets and related property and equipment of $0.4 million related to a leased property in Stevenage, United Kingdom. There was no impairment recognized for the three months ended September 30, 2022.

Other expenses, net

Other expenses, net decreased to $1.6 million for the three months ended September 30, 2023 from $3.7 million for the three months ended September 30, 2022. The decrease of $2.1 million is primarily due to lower foreign exchange losses for the three months ended September 30, 2023 as compared to the three months ended September 30, 2022.

Interest income

Interest income increased to $3.6 million for the three months ended September 30, 2023, as compared to $0.2 million for the three months ended September 30, 2022. The increase in interest income of $3.4 million primarily relates to increase in yield and also higher account balances associated with our cash and cash equivalents during the three months ended September 30, 2023 as compared to the three months ended September 30, 2022.

Interest expense

Interest expense increased to $5.0 million for the three months ended September 30, 2023 as compared to $1.9 million for the three months ended September 30, 2022. Interest expense increased by $3.1 million primarily due to an increase in the balance of the liability for future royalties and sales milestones, net associated with our strategic collaboration agreement with Blackstone.

Income Tax Benefit

Income tax benefit decreased by $1.2 million to $4.9 million for the three months ended September 30, 2023 from $6.2 million for the three months ended September 30, 2022 due to a combination of a decrease in qualifying research and development expenditures, a reduction in effective tax rate related to the U.K. research and development tax credit regime under the scheme for SMEs, partially offset by an adjustment arising from the finalization of our prior year tax returns.

Research and development expenses decreased by $4.5 million to $105.3 million for the nine months ended September 30, 2023 from $109.8 million for the nine months ended September 30, 2022 primarily due to:

•a decrease of $15.5 million in clinical costs and manufacturing costs primarily relating to our obe-cel clinical product candidate,

•a decrease of $1.2 million in depreciation and amortization related to property, plant and equipment and intangible assets,

•a decrease of $1.1 million in legal fees and professional consulting fees in relation to our research and development activities,

•a decrease of $0.1 million related to general office expense,

•a decrease of $0.1 million in material transportation costs, offset by:

•an increase of $6.1 million in salaries and other employment related costs including share-based compensation expense, which was mainly driven by an increase in the number of employees engaged in research and development activities,

•an increase of $5.2 million in facilities costs related to our new manufacturing facility, The Nucleus, in Stevenage, United Kingdom as well as increases in costs related to maintaining our current leased properties, and

•an increase of $2.2 million related to information technology infrastructure and support for information systems related to our new manufacturing facility.

General and Administrative Expenses

General and administrative expenses increased by $6.5 million to $31.0 million for the nine months ended September 30, 2023 from $24.5 million for the nine months ended September 30, 2022 primarily due to:

•an increase of $3.9 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 general and administrative activities,

•an increase of $2.0 million in commercial readiness costs due to increased commercial readiness activities being undertaken,

•an increase of $0.5 million related to information technology infrastructure and support for information systems related to the conduct of corporate and commercial operations,

•an increase of $0.4 million in facility costs due to the increase in space utilized for general and administrative activities and related to general office expenses,

•an increase of $0.2 million in depreciation and amortization related to property, plant and equipment and intangible assets, offset by:

•a decrease of $0.5 million primarily related to a reduction in directors' and officers' liability insurance premiums, legal and professional fees.

Loss on disposal of property and equipment

For the nine months ended September 30, 2023, we recognized a loss on disposal of property and equipment of $3.8 million related to fixed assets no longer being utilized in the manufacturing facility exited in Stevenage, United Kingdom and in a leased property in Stevenage, United Kingdom. There were no such disposals for the nine months ended September 30, 2022.

Impairment of operating lease right-of-use assets and related property and equipment

For the nine months ended September 30, 2023, we recognized an impairment loss on operating lease right-of-use assets and related property and equipment of $0.4 million related to a leased property in Stevenage, United Kingdom. There was no impairment recognized for the nine months ended September 30, 2022.

Other expenses, net

Other expenses, net decreased to $0.3 million for the nine months ended September 30, 2023 from $4.2 million for the nine months ended September 30, 2022. The decrease of $3.9 million is primarily due to lower foreign exchange losses of $4.1 million, offset by a lease termination loss of $0.1 million and an increase of other expenses of $0.1 million for the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022.

Interest Income

Interest income increased to $10.5 million for the nine months ended September 30, 2023, as compared to $0.3 million for the nine months ended September 30, 2022. The increase in interest income of $10.2 million primarily relates to increase in yield and higher account balances associated with our cash and cash equivalents during the nine months ended September 30, 2023 as compared to the nine months ended September 30, 2022.

Interest Expense

Interest expense increased to $14.9 million for the nine months ended September 30, 2023 as compared to $5.4 million for the nine months ended September 30, 2022. Interest expense increased by $9.5 million primarily due to an increase in the balance of the liability for future royalties and sales milestones, net associated with our strategic collaboration agreement with Blackstone.

Income Tax Benefit

Income tax benefit decreased by $6.9 million to $12.4 million for the nine months ended September 30, 2023 from $19.3 million for the nine months ended September 30, 2022 due to a decrease in qualifying research and development expenditures and the reduction in effective tax rate related to the U.K. research and development tax credit regime under the scheme for SMEs, partially offset by an adjustment arising from the finalization of our prior year tax returns.

Liquidity and Capital Resources

Since our inception, we have not generated any commercial product revenue and have incurred operating losses and negative cash flows from our operations. We expect to incur significant expenses and operating losses for the foreseeable future as we advance our product candidates through preclinical and clinical development and seek regulatory approval and pursue commercialization of any approved product candidates. We expect that our research and development and general and administrative expenses may increase in connection with our planned research, clinical development and potential commercialization activities. As a result, we will need significant additional capital to fund our operations until such time as we can generate significant revenue from product sales.

We do not currently have any approved products and have never generated any commercial revenue from product sales. We have funded our operations to date primarily with proceeds from government grants, sales of our equity securities, through public offerings and sales pursuant to our at-the-market facility, reimbursable U.K. research and development tax credits and receipts from the U.K. RDEC scheme, out-licensing arrangements and strategic collaboration agreements. From our inception in 2014 through September 30, 2023, we have raised $1.1 billion from these capital sources.

As of September 30, 2023, we had cash and cash equivalents of $256.4 million.

Cash Flows

The following table summarizes our cash flows for each of the periods presented (in thousands):


	Nine Months Ended September 30,
	2023		2022
Net cash used in operating activities	$	(120,754)	$	(97,742)
Net cash used in investing activities	(9,509)		(10,208)

Net decrease in cash, cash equivalents and restricted cash	$	(125,912)	$	(147,308)

Net Cash Used in Operating Activities

During the nine months ended September 30, 2023, operating activities used $120.8 million of cash, resulting from our net loss of $131.2 million, and net cash used resulting from changes in our operating assets and liabilities of $20.5 million, partially offset by non-cash charges of $31.0 million. Net cash used in operating activities resulting from changes in our operating assets and liabilities for the nine months ended September 30, 2023 consisted primarily of decreases in accrued expenses and other liabilities of $6.8 million, a $9.0 million decrease in current and non-current operating lease liabilities, net of operating lease right of use assets, and a net increase of $5.7 million in prepaid expenses and other current and non-current assets, offset by an increase in accounts payable of $0.1 million and a decrease in long-term deposits of $0.9 million.

During the nine months ended September 30, 2022, operating activities used $97.7 million of cash, resulting from our net loss of $121.9 million, and net cash used resulting from changes in our operating assets and liabilities of $5.6 million, partially offset by non-cash charges of $29.8 million. Net cash used in operating activities resulting from changes in our operating assets and liabilities for the nine months ended September 30, 2022 consisted primarily of a $20.5 million increase in prepaid expenses and other current and non-current assets and an increase in accrued expenses and other liabilities of $15.5 million. This cash used was offset by a decrease in accounts payable of $0.1 million and a $0.5 million decrease in right of use assets from amortization and operating lease liabilities, net.

Net Cash Used in Investing Activities

During the nine months ended September 30, 2023 and 2022, we used $9.5 million and $10.2 million, respectively, of cash in investing activities, all of which consisted of purchases of property and equipment. Property and equipment purchased during the nine months ended September 30, 2023 related primarily to assets under construction associated with the fit-out of the Nucleus manufacturing facility.

Net Cash (used in) provided by Financing Activities

During the nine months ended September 30, 2023, net cash used in financing activities primarily relates to payments of issuance costs relating to prior financings of $0.9 million. During the nine months ended September 30, 2022 net cash provided by financing activities of $0.1 million primarily relates to proceeds received from the exercise of share options.

Funding Requirements

We expect our expenses to increase substantially in connection with our ongoing activities, particularly as we continue pre-commercial activities for obe-cel, complete the qualification of our new commercial manufacturing facility and advance the preclinical activities and clinical trials of our product candidates. Our expenses will increase as we:

•seek regulatory approvals for obe-cel or any other product candidates that successfully complete preclinical and clinical trials;

•establish a sales, marketing and distribution infrastructure in anticipation of commercializing of any product candidates for which we may obtain marketing approval and intend to commercialize on our own or jointly;

•hire additional 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, and we expect will continue to be, compensation and related expenses, clinical costs, external research and development services, laboratory and related supplies, legal and other regulatory expenses, 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.

Based on our current clinical development plans, we believe our current cash and cash equivalents will be sufficient to fund our current and planned operating expenses and capital expenditure requirements for at least the next twelve months from the date of the issuance of these unaudited condensed consolidated financial statements. 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 obe-cel or any of 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:

•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 any of our product candidates for which we receive marketing approval;

•the revenue, if any, received from commercial sale of our products, should any of our product candidates 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 U.K. research and development tax credits and receipts from the U.K. RDEC scheme, out-licensing arrangements, 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, licensing arrangements 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 financial statements, which we have prepared in accordance with generally accepted accounting principles in the United States, "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 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.

We included an update to our significant judgements and accounting estimates from those described in "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our Annual Report.

Lease Term—Impact on Right-of-Use Assets and Lease Liabilities

In September 2021, we entered into an arrangement for lease with the landlord, Forge Life Sciences Nominee, an affiliate of the Reef Group, for the design, construction and lease of our new 70,000 square foot commercial manufacturing facility, referred to as, The Nucleus, in Stevenage, United Kingdom. Under this arrangement, the landlord leased the facility to us on agreed terms, upon satisfaction of certain conditions and completion of construction. Beginning in November 2022, the landlord handed over various portions of the facility to us; on July 31, 2023, they confirmed practical completion of The Nucleus. We were required to pay a pro-rated license fee for each portion of the facility which we were granted access until execution of the lease agreement. As the landlord provided us with access to portions of the facility, the definition of a lease in accordance with ASC 842, was met. The lease term can materially impact the value of the right of use assets and lease liabilities recorded on our balance sheet as required under ASC 842.

On September 19, 2023, we entered into a 20-year lease agreement with Forge Life Sciences Nominee for The Nucleus. We calculated the lease term for The Nucleus by taking into account, the noncancellable period specified in the agreement together with the periods a license fee was payable by us to the landlord for portions of The Nucleus handed over to us. The foregoing description of the Nucleus lease is qualified in its entirety by the lease itself, which we will file as an exhibit to our Annual Report for FY2023.

JOBS Act

The Jumpstart Our Business Startups Act, or the JOBS Act, provides that, among other things, an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. As an emerging growth company, we have irrevocably elected not to take advantage of the extended transition period afforded by the JOBS Act for implementation of new or revised accounting standards and, as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth public companies until the date we are no longer an emerging growth company.

We also currently rely on other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, we are not required to, among other things, (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b), (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis), or (iv) disclose certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of the chief executive officer’s compensation to median employee compensation.

As of December 31, 2023, we will no longer be an emerging growth company. As a result, we will no longer be able to take advantage of reduced disclosure and other obligations that are available to emerging growth companies after that date.

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 financial statements included in Exhibit 99.1 of this Report on Form 6-K.

Autolus Therapeutics Reports Third Quarter 2023 Financial Results and Business Updates November 2, 2023 at 7:12 AM EDT Obe-cel, a potentially transformational treatment for relapsed/refractory (r/r) adult B-cell Acute Lymphoblastic Leukemia (ALL), on track for a Biologics License Application (BLA) submission to the US Food & Drug Administration (FDA) by end of 2023 Updated clinical data at the American Society of Hematology (ASH) meeting in December 2023: Long-term follow-up and sub-group analysis from the FELIX trial of obe-cel and initial data from a study of AUTO8 in multiple myeloma Continued progress with commercial manufacturing facility, The Nucleus, with process performance qualification production phase complete and data package on track to support BLA submission Obe-cel Phase 1 study in refractory systemic lupus erythematosus (SLE) expected to initiate in early 2024 Conference call to be held today at 09:00 am EDT/1:00 pm GMT: Conference call participants should pre-register using the link at the bottom of this press release LONDON, Nov. 02, 2023 (GLOBE NEWSWIRE) -- Autolus Therapeutics plc (Nasdaq: AUTL), a clinical-stage biopharmaceutical company developing next-generation programmed T cell therapies, today announced its operational and financial results for the quarter ended September 30, 2023. “The coming months will be an exciting and instrumental time for Autolus as we plan for our first BLA submission for obe-cel with the US FDA by year end and we continue with our preparatory activities for a planned commercial launch in 2024, pending the necessary regulatory approvals,” said Dr. Christian Itin, Chief Executive Officer of Autolus. “The data we have observed to date in the FELIX study highlights the potential of obe-cel to deliver a high complete remission rate combined with low levels of immunotoxicity and excellent CAR T expansion and persistence in adult patients with relapsed/refractory ALL. We look forward to building on the positive data when we present longer term follow up and additional subgroup analysis data at ASH in December.” “Alongside this, our commercial manufacturing facility, The Nucleus, completed process performance qualification activities in Q4 to support the BLA submission, and we believe we are in a strong position operationally to deliver product and meet the global demand for adult ALL treatment.” “Obe-cel’s excellent risk/benefit profile combined with its ability to make deep cuts into the CD19+ cell compartment, as illustrated by MRD-negative complete remissions in adult and pediatric ALL patients, is a strong foundation for the development of obe-cel in autoimmune disease. The clinical profile together with our commercial product delivery base, attractive cost of goods, and commercial infrastructure should help to drive an accelerated and differentiated expansion of the obe-cel opportunity. We are excited at the growing body of evidence that CAR T can address a significant unmet need in autoimmune disease, and we look forward to starting a Phase I study of obe-cel in refractory systemic lupus erythematosus (SLE) patients in early 2024.” Key obecabtagene autoleucel (obe-cel) updates and anticipated milestones: Obe-cel in relapsed / refractory (r/r) adult ALL – The FELIX Study Longer term follow-up data and subgroup analysis data will be presented at ASH in December 2023, as well as at medical conferences in H1 2024. BLA submission is on track to the FDA by the end of 2023 and a submission of a marketing authorization application to the European Medicines Agency (EMA) in the first half of 2024. Obe-cel in B-cell mediated autoimmune diseases Phase 1 study in refractory SLE patients is on track to start in early 2024, with initial clinical data expected in late 2024. Pipeline clinical trials, in collaboration with University College London (UCL), updates and anticipated milestones AUTO1/22 in pediatric B-ALL patients – Phase 1 CARPALL Study The data presented at European Society for Blood and Marrow Transplantation (EBMT) in April 2023 on the AUTO1/22 Phase 1 CARPALL study was published in Blood, in August 2023, entitled ‘CD19/CD22 targeting with co-transduced CAR T-cells to prevent antigen negative relapse after CAR T-cell therapy of B-ALL’. AUTO8 in Multiple Myeloma – Phase 1 MCARTY Study

AUTO8 is a next-generation product candidate for multiple myeloma, which comprises two CARs for the multiple myeloma targets, BCMA and CD19. In collaboration with UCL, the Company initiated a study in 2022. Patients continue to be enrolled and initial data will be presented at ASH in December 2023. AUTO6NG in Neuroblastoma – Phase 1 MAGNETO Study AUTO6NG contains a CAR that targets GD2 alongside additional programming modules to enhance the activity and persistence. UCL has received MHRA approval for the conduct of a Phase 1 clinical study in children with r/r neuroblastoma. The study is on track to be initiated in Q4 2023. Key Operational Updates during Q3 2023 The Company’s new 70,000 square foot commercial manufacturing facility, The Nucleus, in Stevenage, UK has completed process performance qualification and is on track to support the BLA submission for obe-cel. The Company estimates capacity of approximately 2,000 batches per annum, which is anticipated to be sufficient to meet US and EU adult ALL demand. Previously announced leadership appointments of Rob Dolski as Chief Financial Officer, effective August 7, 2023, as well as Dr. Veronica Hersberger as Senior Vice President, Medical Affairs and Miranda Neville as Senior Vice President Program Management.

Total operating expenses, net for the three months ended September 30, 2023, were $47.8 million, as compared to $43.5 million, for the same period in 2022. Research and development expenses decreased by $0.4 million to $37.2 million for the three months ended September 30, 2023 compared to the same period in 2022. This change was primarily due to decreases in clinical and manufacturing costs related to the Company’s obe-cel clinical program partially offset by increases in operating costs related to the Company’s new commercial manufacturing facility and in salaries and related costs driven by increased headcount. General and administrative expenses increased by $2.4 million to $10.6 million for the three months ended September 30, 2023 compared to the same period in 2022. This increase was primarily due to salaries and other employment-related costs driven by an increase in general and administrative headcount supporting the overall growth of the business, primarily relating to pre-commercialization activities. Net loss attributable to ordinary shareholders was $45.8 million for the three months ended September 30, 2023, compared to $42.8 million for the same period in 2022. The basic and diluted net loss per ordinary share for the three months ended September 30, 2023, totaled $(0.26) compared to a basic and diluted net loss per ordinary share of $(0.47) for the three months ended September 30, 2022. Autolus estimates that its current cash and cash equivalents on hand and anticipated future milestone payment from Blackstone will extend the Company’s cash runway into 2025.

About Autolus Therapeutics plc Autolus is a clinical-stage biopharmaceutical company developing next-generation, programmed T cell therapies for the treatment of cancer and autoimmune disease. Using a 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 eliminate these cells. Autolus has a pipeline of product candidates in development for the treatment of hematological malignancies, solid tumors and autoimmune diseases. For more information, please visit www.autolus.com. About obe-cel (AUTO1) Obe-cel is a CD19 CAR T cell investigational therapy designed to overcome the limitations in clinical activity and safety compared to current CD19 CAR T cell therapies. Obe-cel is designed with a fast target binding off-rate to minimize excessive activation of the programmed T cells. Clinical trials of obe-cel have demonstrated that this “fast off-rate” profile reduces toxicity and T cell exhaustion, resulting in improved persistence and leading to high levels of durable remissions in r/r Adult ALL patients. The results of the FELIX trial, a pivotal trial for adult ALL, are being prepared for regulatory submissions with the FDA and EMA. In collaboration with Autolus’ academic partner, UCL, obe-cel is currently being evaluated in a Phase 1 clinical trials for B-NHL. About obe-cel FELIX clinical trial Autolus’ Phase Ib/II clinical trial of obe-cel enrolled adult patients with relapsed / refractory B-precursor ALL. The trial had a Phase Ib component prior to proceeding to the single arm, Phase II clinical trial. The primary endpoint is overall response rate, and the secondary endpoints include duration of response, MRD negative CR rate and safety. The trial enrolled over 100 patients across 30 of the leading academic and non-academic centers in the United States, United Kingdom and Europe. [NCT04404660] About AUTO1/22 AUTO1/22 is a novel dual targeting CAR T cell-based therapy candidate based on obe-cel. It is designed to combine the enhanced safety, robust

expansion and persistence seen with the fast off rate CD19 CAR from obe-cel with a high sensitivity CD22 CAR to reduce antigen negative relapses. This product candidate is currently in a Phase I clinical trial for patients with r/r pediatric ALL. [NCT02443831] About AUTO6NG AUTO6NG is a next generation programmed T cell product candidate in pre-clinical development. AUTO6NG builds on preliminary proof of concept data from AUTO6, a CAR targeting GD2-expression cancer cell currently in clinical development for the treatment of neuroblastoma. AUTO6NG incorporates additional cell programming modules to overcome immune suppressive defense mechanisms in the tumor microenvironment, in addition to endowing the CAR T cells with extended persistence capacity. AUTO6NG is currently in pre-clinical development for the potential treatment of both neuroblastoma and other GD2-expressing solid tumors. About AUTO8 AUTO8 is a next-generation product candidate for multiple myeloma which comprises two independent CARs for the multiple myeloma targets, BCMA and CD19. We have developed an optimized BCMA CAR which is designed for improved killing of target cell that express BCMA at low levels. This has been combined with fast off rate CD19 CAR from obe-cel. We believe that the design of AUTO8 has the potential to induce deep and durable responses and extend the durability of effect over other BCMA CARs currently in development. This product candidate is currently in a Phase I clinical trial for patients with r/r multiple myeloma.
