PARIS and CAMBRIDGE, Mass., May 22, 2026 (GLOBE NEWSWIRE) — NANOBIOTIX (Euronext: NANO – NASDAQ: NBTX – “Nanobiotix” or the “Company”), a late-clinical stage biotechnology company pioneering physics-based approaches to expand treatment possibilities for patients with cancer and other major diseases, announces that the underwriters of its previously announced global offering (the “Global Offering”) have fully exercised their option to purchase 33,805 additional new ordinary shares in the form of additional American Depositary Shares (the “Additional ADSs”) (the “Option”). Each Additional ADS represents one ordinary share, €0.03 nominal value per share (each an “Ordinary Share”), of the Company and the offering price of $38.98 per Additional ADS corresponds to a price of €33.60 per Ordinary Share (on the basis of an exchange rate of $1.16 = €1.00). The Additional ADSs will be delivered concurrently with the closing of the Global Offering which is expected to occur on May 26, 2026.
Following the full exercise of the Option, the total number of Ordinary Shares and pre-funded warrants (the “PFW”) issued in the Global Offering will amount to 2,218,467 Ordinary Shares, including 259,178 Ordinary Shares in the form of ADSs, and 345,099 PFW, resulting in aggregate gross proceeds for the Company of approximately $100 million (corresponding to approximately €86.1 million), before deducting underwriting commissions in respect of the Global Offering and estimated expenses related to the Global Offering.
The subscription price of €33.60 per Ordinary Share, corresponding to the offering price of $38.98 per ADS based on an exchange rate of €1.00 = $1.16 as published by the European Central Bank on May 20, 2026, is equal to the volume weighted average price of the Ordinary Shares on the regulated market of Euronext in Paris over the last three trading sessions preceding the pricing of the Global Offering (i.e. May 18, May 19 and May 20, 2026), less a discount of 14.92% and has been determined by the Company pursuant to the 29th resolution of the Company’s combined shareholders’ meeting held on May 19, 2025. The subscription price of each PFW is equal to the subscription price per Ordinary Share issued in the Global Offering minus €0.03.
The Company intends to use the net proceeds from the Global Offering, including the net proceeds from the sale of the Additional ADSs, as follows:
- less than 10% to support the development and advancement of JNJ-1900 (NBTXR3);
- between 50-60% to advance our Nanoprimer and other platforms; and
- between 30-40% for general corporate purposes.
The expected use of proceeds represents the Company’s intentions based upon its current plans and business conditions. The Company cannot predict with certainty all of the particular uses for the net proceeds to be received upon the completion of Global Offering (including the Additional ADSs) or the amounts that the Company will actually spend on the uses set forth above. The amounts and timing of the Company’s actual expenditures and the extent of clinical development may vary significantly depending on numerous factors, including the progress of the development efforts, the status of and results from preclinical studies and any ongoing clinical trials or clinical trials the Company may commence in the future, as well as any collaborations that the Company may enter into with third parties for its product candidates and any unforeseen cash needs. As a result, the Company’s management will retain broad discretion over the allocation of the net proceeds.
The Company believes that the net proceeds from the Global Offering (including the Additional ADSs), together with its cash and cash equivalents, will be sufficient to meet its working capital requirements for operations into 2029, consistent with the Company’s currently contemplated cash burn rate.
Jefferies, TD Cowen and Stifel acted as global coordinators and joint bookrunners for the Global Offering.
Jefferies LLC, acting as the stabilizing agent on its own behalf and on behalf of the other Underwriters, reported that no stabilization activities had been carried out and the stabilization period is now closed.
The ADSs are listed on the Nasdaq Global Select Market under the symbol “NBTX” and the Company’s Ordinary Shares are listed on Euronext Paris under the symbol “NANO”.
The ADSs (including the Additional ADSs) and Ordinary Shares issued in the Global Offering were offered pursuant to an effective shelf registration statement on Form F-3 (Registration No. 333-285604), which was filed with the Securities and Exchange Commission (the “SEC”) on March 6, 2025 and subsequently declared effective on March 14, 2025. The Global Offering was made only by means of a prospectus and prospectus supplement that form a part of the registration statement. A preliminary prospectus supplement relating to and describing the terms of the Global Offering has been filed with the SEC on May 20, 2026 and is available on the SEC’s website at www.sec.gov. The final prospectus supplement relating to the Global Offering will be filed with the SEC.
