Liu and Ms. Anat Naschitz as board observers in 3Q2024, two key additions intended to further equip the Company for sustainable long-term growth. Dr. Liu brings a wealth of experience in US and international academia, pharmaceuticals, biotechnology and public policyMs. Naschitz brings world-class expertise in raising and deploying capital to support disruptive innovation for the benefit of patients, healthcare professionals and investors Launched the Curadigm Nanoprimer Platform, the Company’s next lever for growth, in 4Q2024 The platform consists of nanoparticles designed with specific physico-chemical properties that allow temporary occupation of the liver cells responsible for therapeutic clearance. This mechanism is intended to increase the blood bioavailability and subsequent accumulation of therapeutics in the targeted tissues, potentially providing the opportunity to increase the efficacy or decrease the toxicity of intravenously administered medicines. As such, it is a potentially ideal technology to be used by both Nanobiotix and potential partners. ____________________1 Potential first-in-class radioenhancer “NBTXR3” was licensed to Johnson & Johnson by Nanobiotix in 2023 and renamed “JNJ-1900” for the purposes of Johnson & Johnson-led clinical development. “2024 was a productive year focused on strong clinical execution and establishing a foundation for the next stage of growth. We expanded into lung cancer with the dosing of the first patient in the CONVERGE Phase 2 trial evaluating the potential of JNJ-1900 (NBTXR3) to enhance the treatment of first-line Stage III lung cancer patients.” said Laurent Levy, co-founder of Nanobiotix and chairman of the executive board. “Conviction in the broad potential of JNJ-1900 (NBTXR3) was further bolstered by the prolonged survival and well-tolerated safety reported across three key programs including Phase 1 data from Study 1100 evaluating NBTXR3 in combination with an anti-PD-1 in recurrent or metastatic head and neck cancer, as well as initial data supporting expansion potential in pancreatic and lung cancer as part of our MD Anderson collaboration. We also introduced our next generation first-in-class nanotherapeutic platform, Curadigm, late in 2024, which we expect to drive additional long-term value. With our financial position strengthened and new data this year in head and neck, lung, pancreatic, and esophageal cancer, we believe Nanobiotix is strongly positioned for impact in 2025 and beyond.” Full Year 2024 Financial Results Revenue and Other Income: Negative Revenues of €7.2 million were recognized in 2024, compared to €36.2 million for the year ended December 31, 2023, in which year significant revenue was recorded in connection with the execution of the license agreement with Janssen as well as the recognition of a development milestone. The negative non-cash revenue impact recognized in 2024 results from the transfer of NANORAY-312 study sponsorship to Janssen, signed at the end of 2024, which amounts to negative €19.3 million and is driven by a one-time recognition of a net liability towards Janssen to reflect this new situation. This one-off, non-cash negative revenue item, that results from application of IFRS 15 revenue recognition accounting principles, is partially offset by Other Revenues that do positively impact Nanobiotix’s cash position including: Sales of Clinical Products and goods to Janssen for €5.9 million, Technology Transfer Services billed to Janssen for €1.8 million, Research Tax Credit for €3.3 million and other income related to collaboration and supply services agreement in Asian territory for €1.0 million. Research and Development (“R&D”) Expenses: R&D expenses consist primarily of preclinical, clinical, and manufacturing expenses related to the development of NBTXR3 (JNJ-1900) and totaled €40.5 million for the twelve-month period ended December 31, 2024, as compared to €38.4 million for the twelve months ended December 31, 2023, a year over year increase of 5%. The increase in net R&D expenses was primarily due to an increase of clinical development activities, driven by the costs related to NANORAY-312 and of its Phase 1 multi-cohort trial of RT-activated NBTXR3 followed by anti-PD-1 checkpoint inhibitors (Study 1100), and the full-year impact of R&D positions that were recruited in 2023. Selling, General and Administrative (“SG&A”) Expenses: SG&A expenses were €20.5 million for the year ended December 31, 2024, compared to €22.0 million for the year ended December 31, 2023. This year-over-year decrease of 7% is mainly due to one-off fees incurred in 2023, consisting of license agreement execution and equity issuance related legal expenses and next to one-off fees paid to a financial advisor for €1.9 million in total. Net loss: Net loss attributable to shareholders was €68.1 million, a year-over-year increase of 72%, or €1.44 per share, for the twelve-month period ended December 31, 2024, which was primarily attributable to the one-off non-cash negative revenue recognition accounting impact. This compares to a net loss of €39.7 million, or €1.08 per share for the year ended December 31, 2023. Cash and Cash Equivalents: As of December 31, 2024, Nanobiotix had €49.7 million in cash and cash equivalents, compared to €75.3 million as of December 31, 2023. Financial Guidance: Based on the current operating plan and financial projections, Nanobiotix anticipates that the cash and cash equivalents of €49.7 million as of December 31, 2024 will fund its operations into mid-2026. The supervisory board of the Company has reviewed the financial statements 2024 on April 2nd, 2025 and the Company’s statutory auditors have finalized their audit and issued on March 31, 2025 a clean opinion on both statutory and consolidated financial statements 2024. “We have recently fortified our financial position and extended our cash runway into mid-2026 by amending our global agreement with Johnson & Johnson. We expect this action to reduce operational burn with immediate effect and this reduction will continue post mid-2026,” said Bart Van Rhijn, chief financial and business officer at Nanobiotix. “This non-dilutive financing solution achieved via the amendment, which we believe signals the increasing shared commitment to JNJ-1900 (NBTXR3), positions us to continue taking the necessary operational and financial steps to ensure the future of our business and our potential to benefit millions of patients around the world with our technology and signifies our continued financial discipline.” Availability of the Full Year 2024 Financial Reports The URD and 20-F are available on the Nanobiotix website here.

About NBTXR3 (JNJ-1900) NBTXR3 (JNJ-1900) is a novel, potentially first-in-class oncology product composed of functionalized hafnium oxide nanoparticles that is administered via one-time intratumoral injection and activated by radiotherapy. Its proof-of-concept was achieved in soft tissue sarcomas for which the product received a European CE mark in 2019. The product candidate’s physics-based mechanism of action (MoA) is designed to induce significant tumor cell death in the injected tumor when activated by radiotherapy, subsequently triggering adaptive immune response and long-term anti-cancer memory. Given the physics-based MoA, Nanobiotix believes that NBTXR3 (JNJ-1900) could be scalable across any solid tumor that can be treated with radiotherapy and across any therapeutic combination, particularly immune checkpoint inhibitors. Radiotherapy-activated NBTXR3 (JNJ-1900) is being evaluated across multiple solid tumor indications as a single agent or in combination with anti-PD-1 immune checkpoint inhibitors, including in NANORAY-312—a global, randomized Phase 3 study in locally advanced head and neck squamous cell cancers. In February 2020, the United States Food and Drug Administration granted regulatory Fast Track designation for the investigation of NBTXR3 (JNJ-1900) activated by radiation therapy, with or without cetuximab, for the treatment of patients with locally advanced HNSCC who are not eligible for platinum-based chemotherapy—the same population being evaluated in the Phase 3 study. Given the Company’s focus areas and balanced against the scalable potential of NBTXR3 (JNJ-1900), Nanobiotix has engaged in a collaboration strategy to expand development of the product candidate in parallel with its priority development pathways. Pursuant to this strategy, in 2019 Nanobiotix entered into a broad, comprehensive clinical research collaboration with The University of Texas MD Anderson Cancer Center to sponsor several Phase 1 and Phase 2 studies evaluating NBTXR3 (JNJ-1900) across tumor types and therapeutic combinations. In 2023 Nanobiotix announced a license agreement for the global co-development and commercialization of NBTXR3 (JNJ-1900) with Janssen Pharmaceutica NV, a Johnson & Johnson company.
