Amtagvi Commercial Business Significant U.S. Commercial Business Growth and Progress in Global Expansion · Demand and awareness: Record Amtagvi demand, catalyzed by a new marketing campaign and an expanded sales team, is driving increased adoption across a growing ATC network and referrals toward earlier treatment. Unaided physician awareness of Amtagvi has nearly tripled during the last year. · Authorized treatment center (ATC) network: The network has grown to more than 95 U.S., Canadian, and Australian ATCs, with at least 110 ATCs expected to be active by the end of 2026. Community ATCs now represent a third of the network and are expected to increase significantly over the next several quarters. · Real-world experience: Multiple real-world studies by Iovance and ATCs using commercial Amtagvi continue to advance, supporting broader adoption of Amtagvi and earlier patient referrals and access. These studies highlight objective response rates (ORRs) of 50% or greater and address identification of tumor harvest sites, accelerated institutional workflows, and improved patient care. · Manufacturing turnaround time: Amtagvi turnaround time is 31 days or less using the only scaled, centralized commercial manufacturing process approved by FDA for TIL therapy. · Australia: The marketing authorization application (MAA) for Amtagvi in Australia was approved by the Therapeutic Goods Administration (TGA), marking the third approval of Amtagvi by global health authorities to date. A high incidence of advanced melanoma in Australia causes more than 1,500 annual deaths. Australian ATCs are currently progressing through the authorization process in parallel with discussions for national reimbursement. · United Kingdom (UK): The MAA for Amtagvi in the UK was resubmitted in early July and is undergoing expedited review by the Medicines and Healthcare products Regulatory Agency (MHRA) for potential approval later in 2026. Advanced melanoma causes more than 2,500 deaths annually in the UK. · Switzerland: Potential approval of the MAA in Switzerland is expected in 1H27, opening a second market opportunity in Europe with the potential for medical tourism. Switzerland’s domestic melanoma burden causes several hundred deaths annually. · Other markets and indications: An MAA resubmission for Amtagvi in advanced melanoma to the European Medicines Agency is on track for 2027. Other regulatory submissions are planned in international markets with a high prevalence of advanced melanoma, NSCLC, and soft tissue sarcomas. Clinical and Regulatory Pipeline Updates Progress Across a Deep Pipeline of Registrational Programs · IOV-LUN-202: Initial results in previously treated metastatic non-squamous NSCLC supported FDA FTD. Enrollment is nearly complete in the pivotal cohorts and program updates are expected in 4Q26. A supplemental Biologics License Application (sBLA) submission is planned in 2027. The U.S. market opportunity in metastatic non-squamous NSCLC is about seven times that of advanced melanoma. · SARATOGA (IOV-SAR-201): The registrational trial in UPS and DDLPS is underway, driven by positive early data with an ORR by RECIST v1.1 of 50% in the first six evaluable patients. Based on the strength of this early data, FDA granted FTD for UPS and DDLPS. Results will be highlighted in an oral presentation (abstract #3725RO) at the European Society for Medical Oncology (ESMO) meeting in Madrid, Spain, from October 23–27, 2026.

· TILVANCE-301: A Phase 3 randomized trial of lifileucel and pembrolizumab is enrolling patients with frontline advanced melanoma across a broad global footprint. The TILVANCE-301 trial includes an early interim analysis based on ORR for a potential sBLA for frontline advanced melanoma. The trial also serves as the confirmatory study for the accelerated approval of lifileucel in second-line advanced melanoma. Results supporting the combination of lifileucel and pembrolizumab as a potential best-in-class option for frontline advanced melanoma were accepted (abstract #2072O) for an oral presentation at the ESMO annual meeting. · IOV-END-201: Positive initial data in previously treated metastatic serous endometrial cancer using a biomarker strategy based on histology were recently reported. A protocol amendment is being submitted and engagement with FDA is underway on an expedited approval pathway to focus on this population. Next-Generation Pipeline Updates First-in-Class Immuno-Oncology Technologies Target New Indications · IOV-GM1-201: A Phase 1/2 trial investigating IOV-4001, a PD-1 inactivated TIL therapy, is enrolling patients with previously treated metastatic melanoma and NSCLC. IOV-4001 is engineered to resist inhibitory signals and enhance the ability of TIL therapies to fight and kill cancer in the tumor microenvironment (TME). · IOV-GE1-201: A Phase 1/2 trial is underway using IOV-5001, a second-generation IL-12 tethered TIL therapy designed to remodel the suppressive TME and activate immunologically “cold tumors” to support TIL responses and boost response rates.2 Cohorts include metastatic colorectal cancer, triple-negative and estrogen receptor low breast cancers, and other solid tumors causing more than 100,000 annual U.S. deaths.3 · IOV-IL2-101: A Phase 1 safety cohort is advancing through multiple dose levels in the Phase 1/2 trial of IOV-3001, our second- generation modified IL-2 analog for the TIL treatment regimen. IOV-3001 selectively expands effector T cells while avoiding activation of regulatory T cells with the potential for a lower dose IL-2 regimen with reduced adverse events. IOV-3001 is expected to be superior to Proleukin as a component of future TIL regimens. · Investigator-sponsored trials (ISTs): Iovance is advancing several lifileucel ISTs in new indications. Multiple patients have been treated for cutaneous squamous cell carcinoma (CSCC) and Merkel cell carcinoma (MCC) with initial data expected in 1H27. To date, early clinical activity has been reported. With no approved therapies after failure of checkpoint inhibitors, lifileucel could address a large CSCC and MCC market with several thousand annual deaths in the U.S. Corporate Updates · Iovance is deploying and advancing artificial intelligence (AI) tools to drive significant future cost efficiencies and new product pipeline insights. · Iovance currently owns or licenses more than 400 granted or allowed U.S. and international patents and patent rights for Amtagvi and other TIL-related technologies and has filed more than 1,000 additional patent applications worldwide. This broad patent portfolio is expected to provide patent exclusivity through at least 2042 and beyond. · As of June 30, 2026, Iovance’s cash position was ~$304 million4 and current cash is expected to fund operations into 2H28.
