Full Year 2022 Financial Results

Revenue and Other Income: No revenue was recognized for the year ended December 31, 2022. The limited revenue during the year ended December 31, 2021, was mainly derived from the charging-back of external contract research organization costs incurred on behalf of former partner PharmaEngine in connection with the now terminated license and collaboration agreement.

Total other income increased significantly to €4.8 million for the year ended December 31, 2022, compared to €2.6 million and €2.5 million for the years ended December 31, 2021, and 2020, respectively, mainly due to higher research tax credit.

Research and Development ("R&D”) Expenses: R&D expenses consist primarily of preclinical, clinical, and manufacturing expenses related to the development of NBTXR3 and totaled €32.6 million for the twelve-month period ended December 31, 2022, as compared to €30.4 million for the twelve months ended December 31, 2021. The increase in net R&D expenses was primarily due to increases in development costs related to the Company’s priority pathways, including initiation of its pivotal Phase 3 registration study, NANORAY-312, continuation of Expansion Study 102 and its ongoing immunotherapy combination Study 1100 as well as increases in personnel related expenses.

Selling, General and Administrative ("SG&A”) Expenses: SG&A expenses decreased by €1.6 million, or 8.1%, from €19.4 million for the year ended December 31, 2021, to €17.9 million for the year ended December 31, 2022. This year-over-year decrease reflects the Company’s efforts to rationalize SG&A and internalize certain functions.

Net loss: Net loss attributable to shareholders was €57.0 million, or €1.64 per share, for the twelve-month period ended December 31, 2022. This compares to a net loss of €47.0 million, or €1.35 per share for the year ended December 31, 2021. Our operating loss decreased from €52.6 million in 2021 to €46.7 million in 2022; this operating loss improvement was offset mainly by a negative €6.9 million one-time debt valuation impact in 2022 as well as higher debt interest charges, together with €3.1 million lower foreign exchange gains.

Cash and Cash Equivalents: As of December 31, 2022, Nanobiotix had €41.4 million in cash and cash equivalents, compared to €83.9 million as of December 31, 2021.

Financial Guidance: Based on the current operating plan and financial projections, Nanobiotix anticipates that the cash and cash equivalents of €41.4 million as of December 31, 2022, in conjunction with its previously announced equity line financing will fund its operations into the third quarter of 2023.

Going Concern: We have prepared our consolidated financial statements assuming that we will continue as a going concern. We experienced net losses of €57.0 million in 2022 and a net decrease in cash and cash equivalents of €42.5 million in 2022. At December 31, 2022, our accumulated deficit was €227.3 million and we had negative working capital of €22.7 million. We expect to continue to incur significant expense related to the development and manufacturing of nanotechnology product candidates such as NBTXR3 and conducting clinical studies. Additionally, we may encounter unforeseen difficulties, complications, development delays and other unknown factors that require additional expense. As a result of these expenditures, we expect to continue to incur significant losses in the near term. Additionally, the EIB loan contain covenants that require maintenance of minimum cash and cash equivalent balances that limit the availability of cash resources to pursue operational needs.

The Company’s covenant obligations entail that the current cash and cash equivalents are only sufficient to fund our operating expenses into the third quarter of 2023. Violation of the covenant would result in immediate repayment of all or part of the loan outstanding (if and when requested by the EIB), together with accrued interest, prepayment fees and all other accrued or outstanding amounts. However, Nanobiotix has obtained a 15 million euros temporary waiver, until July 31, 2023, and has reached an agreement in principle with the EIB to automatically extend it until January 31, 2024 should a business development partnership, collaborative or strategic alliance have become effective before July 31, 2023. If the company secures this extension period, or if the company obtains appropriate funding prior, the Company is not expected to be in breach of this temporary waiver as of July 31, 2023.

The Company is also pursuing additional funding through one or more possible new partnerships, collaborative or strategic alliances; or from the use of the equity line (PACEO) signed with Kepler Cheuvreux, financing from institutional or strategic investors, from the capital markets, or a combination of the above. However, the Company cannot guarantee if or when any such transactions will occur or whether they will be on satisfactory terms.

While the Company has taken and will continue to take actions to obtain new funding and manage costs through operating expense reduction plans, as necessary, the above factors indicate substantial risk about the Company’s ability to continue as a going concern as there is no assurance that the Company will be successful in satisfying its future cash needs.

Subsequently, the Executive Board determined it is appropriate to prepare consolidated financial statements as of and for the period ended December 31, 2022, applying a going concern basis, assuming the Company will continue to operate for the foreseeable future. The supervisory board of the Company has reviewed and closed the FY 2022 on April 24, 2023.

About NBTXR3

NBTXR3 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. The product candidate’s physical 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 physical MoA, Nanobiotix believes that NBTXR3 could be scalable across any solid tumor that can be treated with radiotherapy and across any therapeutic combination, particularly immune checkpoint inhibitors.

NBTXR3 is being evaluated in locally advanced head and neck squamous cell carcinoma (HNSCC) as the primary development pathway. The company-sponsored Phase 1 dose escalation and dose expansion study has produced favorable safety data and early signs of efficacy; and a Phase 3 global registrational study was launched in 2021. 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—the same population being evaluated in the Phase 3 study.

Nanobiotix has also prioritized an Immuno-Oncology development program—beginning with a Company-sponsored Phase 1 clinical study evaluating NBTXR3 activated by radiotherapy in combination with anti-PD-1 checkpoint inhibitors for patients with locoregional recurrent or recurrent/metastatic HNSCC, or lung or liver metastases from any primary cancer eligible for anti-PD-1 therapy.

Given the Company’s focus areas, and balanced against the scalable potential of NBTXR3, Nanobiotix has engaged in a strategic collaboration strategy with world class partners 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 to evaluate NBTXR3 across tumor types and therapeutic combinations.
