With mounting experience we see physician enthusiasm for AUCATZYL increasing, validated by real world data from the ROCCA Consortium to be presented at the ASH Annual Meeting in December,” said Dr. Christian Itin, Chief Executive Officer of Autolus. “Despite an expected temporary lag in Q3 sales based on the change in CMS reimbursement policy that occurred in Q2, we executed well on new patient starts and project a strong full year of sales.” Dr. Itin continued, “Building on our strong commercial and manufacturing performance, we enter our next phase of growth for obe-cel focused on three key objectives. First, increasing market share within the indicated adult ALL population; second, based on strong Phase 1 data sets we are conducting potential pivotal studies in pediatric ALL and in severe lupus nephritis to broaden the utility and commercial opportunity of obe-cel; and finally, we continue to innovate on manufacturing technology as a foundation for further expansion of access to CAR T therapies.” Product and Pipeline Updates: AUCATZYL® Launch Autolus reported net product revenue of $21.1 million for the three months ended September 30, 2025 and deferred revenue of $7.6 million as of September 30, 2025.The Company has 60 centers fully activated in the U.S. as of November 12, 2025, achieving the target of 60 activated centers prior to year-end.Patient access to AUCATZYL continues to increase, with coverage secured for greater than 90% of total U.S. medical lives.Data from the ROCCA (Real-World Outcomes Collaborative for CAR T in Adult ALL) database evaluating patient characteristics, toxicity and response after real-world administration of AUCATZYL (obecabtagene autoleucel) and TECARTUS (brexucabtagene autoleucel) for relapsed acute lymphoblastic leukemia with r/r ALL will be presented at the American Society of Hematology (ASH) Annual Meeting. Obe-cel data in pediatric r/r B-ALL Data from the ongoing Phase Ib/II CATULUS study evaluating the safety and efficacy of obe-cel in patients under 18 years with CD19-positive r/r B-ALL or B-cell Non-Hodgkin Lymphoma (NHL) will be presented at the American Society of Hematology Annual Meeting. Data show the safety profile of obe-cel in pediatric patients is consistent with that previously reported in adults, with low rates of high-grade cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). Overall response rate (ORR) was high at 95% and nearly 90% of responders had ongoing remission at data cut-off. Additional data will be presented in a poster presentation at the ASH Annual Meeting on December 7, 2025, from 6:00 – 8:00pm ET.In October 2025, the U.S. Food and Drug Administration (FDA) granted regenerative medicine advanced therapy (RMAT) designation to obe-cel for the treatment of pediatric patients with r/r B-ALL. The RMAT designation is a program created under the 21st Century Cures Act to accelerate development and regulatory review of regenerative medicine therapies, including cell therapies, intended to treat serious or life-threatening diseases. Obe-cel in lupus nephritis (LN) Data from the Phase 1 CARLYSLE clinical trial were presented on October 28, 2025, at the American College of Rheumatology (ACR) Convergence 2025. Data in severe refractory systemic lupus erythematosus (srSLE) suggests obe-cel is well tolerated with no ICANS or high-grade CRS. Preliminary efficacy data demonstrate achievement of definition of remission in SLE (DORIS) in 83% (n=5/6) of patients and complete renal response (CRR) in 50% (n=3/6) of patients. All responses and remissions are ongoing with no evidence of disease activity at a median follow up of 8.9 months (range 6-13.8 months).Additional findings from the ongoing CARLYSLE study will be presented in an oral presentation at the American Society of Hematology (ASH) Annual Meeting 2025 on December 8, 2025, at 11:30am ET. Data show the B-cell reconstitution profiles suggest that obe-cel may induce a reset of pathologic autoimmunity. Updated Phase 1 data with longer follow-up, and data in patients who received 100×106 CAR T-cells will be presented.The Company has previously aligned with the FDA on the Phase 2 trial design and potential registrational path to approval. Data to date supported progressing into the Phase 2 LUMINA trial. The first patient is expected to be dosed prior to year-end 2025. Obe-cel in progressive MS Autolus is advancing obe-cel into initial clinical development in progressive MS. The first patient in the BOBCAT trial was dosed in October 2025. The Phase 1 trial, expected to include up to 18 adult patients, will determine the safety, tolerability, and preliminary efficacy of obe-cel in participants with refractory progressive forms of multiple sclerosis. The primary endpoint is to assess safety and tolerability of obe-cel. Key secondary endpoints include evaluating the preliminary efficacy of obe-cel using change from baseline in standard efficacy measures. Early-stage pipeline programs and collaborations In November 2025, Moderna announced that the first patient has been dosed in a Phase 1/2 study of mRNA-2808, an investigational mRNA-based T-cell engager for participants with relapsed or refractory multiple myeloma. mRNA-2808 utilizes an Autolus proprietary binder that was licensed to Moderna in 2022.Long term follow up from the AUTO8 MCARTY study in multiple myeloma will be presented in a poster presentation at the ASH Annual Meeting:Abstract ID: abs25-14286Title: CAR-T cells co-targeting BCMA and CD19 in RRMM: Results from the UKMRA Phase 1 MCARTY trial in relapsed refractory multiple myelomaDate: December 7, 06:00 PM - 08:00 PM ESTLocation: OCCC - West Halls B3-B4Presenting Author: Lydia Lee, MBBS, MRCP, MRCPath (Haem), PhDThe first patient in the AUTO8 ALARIC study in AL Amyloidosis is expected to be dosed prior to year-end 2025.Autolus’ translational programs with UCL continue to fuel its early-stage pipeline, providing a cost-efficient path to development to support long-term growth.

Deferred revenue balance at September 30, 2025, was $7.6 million, representing product that was shipped and received by centers but not yet dosed. Cost of sales for the three months ended September 30, 2025, totaled $28.6 million. This amount includes the cost of all commercial product delivered to the authorized treatment centers, including product delivered but not yet recorded as product revenue which is captured as deferred revenue. Additionally, cost of sales includes any cancelled orders in the period, patient access program product, inventory reserves and write-offs and 3rd party royalties for certain technology licenses. Research and development expenses decreased from $40.3 million to $27.9 million for the three months ended September 30, 2025, compared to the same period in 2024. This change was primarily due to commercial manufacturing-related employee and infrastructure costs shifting to cost of sales and inventory. Selling, general and administrative expenses increased from $27.3 million to $36.3 million for the three months ended September 30, 2025, compared to the same period in 2024. This increase was primarily due to salaries and other employment-related costs, driven by increased headcount supporting commercialization activities. Loss from operations for the three months ended September 30, 2025, was $71.6 million, as compared to $67.9 million for the same period in 2024. Net loss was $79.1 million for the three months ended September 30, 2025, compared to $82.1 million for the same period in 2024. Basic and diluted net loss per ordinary share for the three months ended September 30, 2025, totaled $(0.30), compared to basic and diluted net loss per ordinary share of $(0.31) for the same period in 2024. Cash, cash equivalents and marketable securities at September 30, 2025, totaled $367.4 million, as compared to $588.0 million at December 31, 2024. The decrease was primarily driven by net cash used in operating activities and impacted by a delayed cash receipt of approximately $20.1 million in the Company's 2023 R&D tax credit expected from the UK HMRC. Autolus estimates that, with its current cash and cash equivalents and marketable securities, the Company is well capitalized to to drive the launch and commercialization of obe-cel in r/r B-ALL and to generate data in the LN and pALL potential pivotal trials and MS Phase 1 trial Financial Results for the Period Ended September 30, 2025Selected Consolidated Balance Sheet Data(In thousands) September 30 December 31 2025 2024Assets Cash and cash equivalents $86,124 $227,380Marketable securities - Available-for-sale debt securities $281,289 $360,643Total current assets $514,577 $660,929Total assets $661,947 $782,725Liabilities and shareholders’ equity Total current liabilities $83,071 $60,743Total liabilities $396,495 $355,400Total shareholders' equity $265,452 $427,325 Selected Consolidated Statements of Operations and Comprehensive Loss Data(In thousands, except share and per share amounts) Three Months EndedSeptember 30, Nine Months EndedSeptember 30, 2025 2024 2025 2024Product revenue, net $21,144 $— $51,049 $—License revenue 50 — 50 10,091Cost and operating expenses: Cost of sales (28,643) — (71,039) —Research and development expenses, net (27,892) (40,323) (82,056) (107,606)Selling, general and administrative expenses (36,280) (27,330) (96,079) (67,410)Loss on disposal of property and equipment — (223) (3) (223)Impairment of operating lease right-of-use assets and related property and equipment — — — (414)Loss from operations (71,621) (67,876) (198,078) (165,562)Total other (expenses) income, net (6,965) (14,196) 4,037 (27,428)Net loss before income tax (78,586) (82,072) (194,041) (192,990)Income tax expenses (532) (22) (3,155) (66)Net loss attributable to ordinary shareholders (79,118) (82,094) (197,196) (193,056)Other comprehensive (loss) income, net of tax (5,782) 27,010 24,254 28,094Total comprehensive loss $(84,900) $(55,084) $(172,942) $(164,962) Basic and diluted net loss per ordinary share $(0.30) $(0.31) $(0.74) $(0.77)Weighted-average basic and diluted ordinary shares 266,141,431 266,084,589 266,136,518 255,480,521 Conference CallManagement will host a conference call and webcast today at 8:30am EST/1:30pm GMT to discuss the company’s financial results.

INDICATION AUCATZYL® is a CD19-directed genetically modified autologous T cell immunotherapy indicated for the treatment of adult patients with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL). IMPORTANT SAFETY INFORMATION WARNING: CYTOKINE RELEASE SYNDROME, NEUROLOGIC TOXICITIES, and SECONDARY HEMATOLOGICAL MALIGNANCIES Cytokine Release Syndrome (CRS) occurred in patients receiving AUCATZYL. Do not administer AUCATZYL to patients with active infection or inflammatory disorders. Prior to administering AUCATZYL, ensure that healthcare providers have immediate access to medications and resuscitative equipment to manage CRS [see Dosage and Administration (2.2,2.3), Warnings and Precautions (5.1)]. Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS), including fatal or life-threatening reactions, occurred in patients receiving AUCATZYL, including concurrently with CRS or after CRS resolution. Monitor for neurologic signs and symptoms after treatment with AUCATZYL. Prior to administering AUCATZYL, ensure that healthcare providers have immediate access to medications and resuscitative equipment to manage neurologic toxicities. Provide supportive care and/or corticosteroids, as needed [see Dosage and Administration (2.2,2.3), Warnings and Precautions (5.2)]. T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies [see Warnings and Precautions (5.8)]. WARNINGS AND PRECAUTIONS Cytokine Release Syndrome (CRS) Cytokine Release Syndrome (CRS) occurred following treatment with AUCATZYL. CRS was reported in 75% (75/100) of patients including Grade 3 CRS in 3% of patients. The median time to onset of CRS was 8 days following the first infusion (range: 1 to 23 days) with a median duration of 5 days (range: 1 to 21 days). The most common manifestations of CRS included fever (100%), hypotension (35%), and hypoxia (19%). Cytokine Release Syndrome (CRS) occurred following treatment with AUCATZYL. CRS was reported in 75% (75/100) of patients including Grade 3 CRS in 3% of patients. The median time to onset of CRS was 8 days (range: 1 to 23 days) with a median duration of 5 days (range: 1 to 21 days). Sixty-eight percent of patients (51/75) experienced CRS after the first infusion, but prior to the second infusion of AUCATZYL with a median time to onset of 6 days (range: 1 to 10 days). Among patients with CRS, the most common manifestations of CRS included fever (100%), hypotension (35%) and hypoxia (19%). The primary treatment for CRS was tocilizumab (73%; 55/75), with patients also receiving corticosteroids (21%; 16/75). Prior to administering AUCATZYL, ensure that healthcare providers have immediate access to medications and resuscitative equipment to manage CRS. During and following treatment with AUCATZYL, closely monitor patients for signs and symptoms of CRS daily for at least 7 days following each infusion. Continue to monitor patients for CRS for at least 2 weeks following each infusion with AUCATZYL. Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time. At the first sign of CRS, immediately evaluate the patient for hospitalization and institute treatment with supportive care based on severity and consider further management per current practice guidelines. Neurologic Toxicities Neurologic toxicities including Immune Effector Cell-associated Neurotoxicity Syndrome (ICANS), which were fatal or life-threatening, occurred following treatment with AUCATZYL. Neurologic toxicities were reported in 64% (64/100) of patients, including Grade ≥ 3 in 12% of patients. The median time to onset of neurologic toxicities was 10 days (range: 1 to 246 days) with a median duration of 13 days (range: 1 to 904 days). Fifty-five percent of patients (35/64) experienced neurologic toxicities after the first infusion but prior to the second infusion of AUCATZYL with a median time to onset of 6 days (range: 1 to 11 days). Among patients with neurologic toxicities, the most common symptoms (> 5%) included ICANS (38%), headache (34%), encephalopathy (33%), dizziness (22%), tremor (13%), anxiety (9%), insomnia (9%), and delirium (8%). Immune Effector Cell-associated Neurotoxicity Syndrome (ICANS) ICANS events occurred in 24% (24/100) of patients, including Grade ≥ 3 in 7% (7/100) of patients. Of the 24 patients who experienced ICANS, 33% (8/24) experienced an onset after the first infusion, but prior to the second infusion of AUCATZYL. The median time to onset for ICANS events after the first infusion was 8 days (range: 1 to 10 days) and 6.5 days (range: 2 to 22 days) after the second infusion, with a median duration of 8.5 days (range: 1 to 53 days). Eighty-eight percent (21/24) of patients received treatment for ICANS. All treated patients received high-dose corticosteroids and 42% (10/24) of patients received anti-epileptics prophylactically. Prior to administering AUCATZYL, ensure that healthcare providers have immediate access to medications and resuscitative equipment to manage ICANS. During and following AUCATZYL administration, closely monitor patients for signs and symptoms of Neurologic Toxicity/ICANS. Following treatment with AUCATZYL, monitor patients daily for at least 7 days. Continue to monitor patients for at least 2 weeks following treatment with AUCATZYL. Avoid driving for at least 2 weeks after each infusion. Counsel patients to seek medical attention should signs or symptoms of neurologic toxicity/ ICANS occur. At the first sign of Neurologic Toxicity/ICANS, immediately evaluate patients for hospitalization and institute treatment with supportive care based on severity and consider further management per current practice guidelines. Prolonged Cytopenias Patients may exhibit cytopenias including anemia, neutropenia, and thrombocytopenia for several weeks after treatment with lymphodepleting chemotherapy and AUCATZYL. In patients who were responders to AUCATZYL, Grade ≥ 3 cytopenias that persisted beyond Day 30 following AUCATZYL infusion were observed in 71% (29/41) of patients and included neutropenia (66%, 27/41) and thrombocytopenia (54%, 22/41). Grade 3 or higher cytopenias that persisted beyond Day 60 following AUCATZYL infusion was observed in 27% (11/41) of patients and included neutropenia (17%, 7/41) and thrombocytopenia (15%, 6/41). Monitor blood counts after AUCATZYL infusion. Infections Severe, including life-threatening and fatal infections occurred in patients after AUCATZYL infusion. Non-COVID-19 infections of all grades occurred in 67% (67/100) of patients. Grade 3 or higher non-COVID-19 infections occurred in 41% (41/100) of patients. AUCATZYL should not be administered to patients with clinically significant active systemic infections. Monitor patients for signs and symptoms of infection before and after AUCATZYL infusion and treat appropriately. Administer prophylactic antimicrobials according to local guidelines. Grade 3 or higher febrile neutropenia was observed in 26% (26/100) of patients after AUCATZYL infusion and may be concurrent with CRS. In the event of febrile neutropenia, evaluate for infection and manage with broad-spectrum antibiotics, fluids, and other supportive care as medically indicated. Viral reactivation, potentially severe or life-threatening, can occur in patients treated with drugs directed against B cells. There is no experience with manufacturing AUCATZYL for patients with a positive test for human immunodeficiency virus (HIV) or with active hepatitis B virus (HBV) or active hepatitis C virus (HCV). Perform screening for HBV, HCV and HIV in accordance with clinical guidelines before collection of cells for manufacturing. Hypogammaglobulinemia Hypogammaglobulinemia and B-cell aplasia can occur in patients after AUCATZYL infusion. Hypogammaglobulinemia was reported in 10% (10/100) of patients treated with AUCATZYL including Grade 3 events in 2 patients (2%). Immunoglobulin levels should be monitored after treatment with AUCATZYL and managed per institutional guidelines including infection precautions, antibiotic or antiviral prophylaxis, and immunoglobulin replacement. The safety of immunization with live viral vaccines during or following treatment with AUCATZYL has not been studied. Vaccination with live viral vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy treatment, during AUCATZYL treatment, and until immune recovery following treatment with AUCATZYL. Hemophagocytic Lymphohistiocytosis/Macrophage Activation Syndrome (HLH/MAS) HLH/MAS including fatal and life-threatening reactions occurred after treatment with AUCATZYL. HLH/MAS was reported in 2% (2/100) of patients and included Grade 3 and Grade 4 events with a time of onset at Day 22 and Day 41, respectively. One patient experienced a concurrent ICANS events after AUCATZYL infusion and died due to sepsis with ongoing HLH/MAS that had not resolved. Administer treatment for HLH/MAS according to institutional standards. Hypersensitivity Reactions Serious hypersensitivity reactions, including anaphylaxis, may occur due to dimethyl sulfoxide (DMSO), an excipient used in AUCATZYL. Observe patients for hypersensitivity reactions during and after AUCATZYL infusion. Secondary Malignancies Patients treated with AUCATZYL may develop secondary malignancies. T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies. Mature T cell malignancies, including CAR-positive tumors, may present as soon as weeks following infusion, and may include fatal outcomes. Monitor lifelong for secondary malignancies. In the event that a secondary malignancy occurs, contact Autolus at 1-855-288-5227 for reporting and to obtain instructions on the collection of patient samples for testing. Adverse Reactions The safety of AUCATZYL was evaluated in the FELIX study in which 100 patients with relapsed or refractory B-cell acute lymphoblastic leukemia (B-ALL) received AUCATZYL at a median dose of 410 × 106 CD19 CAR-positive viable T cells (range: 10 to 480 × 106 CD19 CAR-positive viable T cells with 90% of patients receiving the recommended dose of 410 × 106 +/- 25%). The most common serious adverse reactions of any Grade (incidence ≥ 2%) included infections-pathogen unspecified, febrile neutropenia, ICANS, CRS, fever, bacterial infectious disorders, encephalopathy, fungal infections, hemorrhage, respiratory failure, hypotension, ascites, HLH/MAS, thrombosis and hypoxia. Nine patients (9%) experienced fatal adverse reactions which included infections (sepsis, pneumonia, peritonitis), ascites, pulmonary embolism, acute respiratory distress syndrome, HLH/MAS and ICANS. Of the 9 patients, five patients who died from infections had pre-existing and ongoing neutropenia prior to receiving bridging therapy, lymphodepletion chemotherapy treatment and/or AUCATZYL.
