“Our progress in the first half of 2026 continues to support our belief that a physics-based approach to the design and development of nanotherapeutics has the potential to revolutionize treatment possibilities for millions of patients around the world,” said Laurent Levy, Chief Executive Officer and Chairman of the Executive Board at Nanobiotix. “The JNJ-1900 (NBTXR3) clinical development program continued to produce encouraging data across multiple indications, and adjustments to the Phase 3 NANORAY-312 protocol streamlined the study toward the final analysis. Longstanding shareholders and new investors alike expressed confidence in our vision through our recent capital raise. We enter the second half strategically, operationally, and financially equipped to continue supporting Nanoradioenhancer JNJ-1900 (NBTXR3) and advancing next wave nanotherapeutic platforms such as Nanoprimer.”

Operational Highlights

Half Year 2026 Financial Results

Revenue and Other Income: Revenue and other income amounted to €5.6 million for the six months ended June 30, 2026, as compared to €26.6 million for the same period in 2025. This variance is mainly due to a significant one-off non-cash revenue positive impact amounting to €21.2 million recorded over the first half of 2025 in accordance with IFRS15 revenue recognition accounting principles, further to the transfer of NANORAY-312 study sponsorship to Johnson & Johnson. In addition, Revenue and Other Income for the six months ended June 30, 2026 also included €3.1 million of clinical product supply sales to Johnson & Johnson (as compared to €3.4 million for the same period in 2025) and research tax credit income amounting to €1.9 million (as compared to €1.6 million for the same period in 2025).

Research and Development (“R&D”) Expenses: R&D expenses consist primarily of preclinical, clinical and manufacturing expenses including employee-related payroll costs and shared-based payment charges related to the development of JNJ-1900 (NBTXR3) and of new platforms. These R&D expenses for the six months ending June 30 2026, were €12.7 million as compared to €14.5 million for the same period in 2025. The €1.8 million favorable variance was primarily driven by lower clinical development and JNJ-1900 (NBTXR3) production activities in NANORAY-312 study further to the transfer of sponsorship to Johnson & Johnson, and by less patient recruitment on the studies Study 1100 and lower UT MD Anderson studies expense during first half of 2026 as compared to the same period in 2025.

Selling, General and Administrative (“SG&A”) Expenses: SG&A expenses consist primarily of administrative employee-related payroll costs, share-based payment charges, insurance, IP, legal, audit and other professional fees. Total SG&A expenses for the six months ending June 30, 2026, were €10.8 million, as compared to €11.3 million for the same period in 2025. The €0.5 million favorable variance is mainly due to the impact of social charges related to stock-option plan and severance expenses occurred over the first half of 2025.

Net loss: Net loss attributable to common shareholders for the six months ending June 30, 2026, was €34.3 million, or a €0.70 basic loss per share. This compares to a net loss attributable to common shareholders of €5.4 million, or €0.11 basic loss per share, for the same period in 2025.

Cash and Cash Equivalents: Cash and Cash Equivalents as of June 30, 2026 were €110.9 million, compared to €52.8 million as of December 31, 2025.

Financial Guidance: Based on the current operating plan and financial projections, the Company anticipates that the cash and cash equivalents of €110.9 million as of June 30, 2026 will fund its operations into 2029.

The 2026 half-year financial report has been filed with the French financial market authority (Autorité des marchés financiers) and with the U.S. Securities and Exchange Commission on September 24, 2026. It is available to the public on the Company’s website, www.nanobiotix.com.

About JNJ-1900 (NBTXR3)

JNJ-1900 (NBTXR3) is a novel, potentially first-in-class oncology product composed of functionalized hafnium oxide nanoparticles administered via one-time intratumoral injection and activated by radiotherapy. The product candidate’s mechanism of action (MoA) is designed to induce significant tumor cell death in the injected tumor when in the presence of radiotherapy, subsequently triggering adaptive immune response and long-term anti-cancer memory. Proof-of-concept was demonstrated in a randomized Phase 2/3 soft tissue sarcoma study sponsored by Nanobiotix in 2018.

JNJ-1900 (NBTXR3) is being evaluated across multiple solid tumor indications as a single agent or combination therapy. Given the Company’s focus areas, and balanced against the scalable potential of NBTXR3, 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 JNJ-1900 (NBTXR3) across tumor types and therapeutic combinations.

In February 2020, the United States Food and Drug Administration granted regulatory Fast Track designation for the investigation of NBTXR3 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.

In 2023, Nanobiotix announced a license agreement for the global development and commercialization of JNJ-1900 (NBTXR3) with Janssen Pharmaceutica NV, a Johnson & Johnson company. Studies being led by Johnson & Johnson include NANORAY-312 (NCT04892173), a global, randomized Phase 3 study in platinum-based chemotherapy-ineligible, locally advanced head and neck squamous cell cancers; LUMIRAY (NCT07219212), a global, phase 1b, open-label study in locally advanced head and neck squamous cell cancers; and CONVERGE (NCT06667908), a phase 2, randomized, open-label, active-controlled study in locally advanced and unresectable Stage III non-small cell lung cancer (NSCLC).
