NurExone Forms Exo-Top Inc. in the U.S. for Exosome Manufacture and Commercialization

NurExone Biologic Inc. (TSXV: NRX) (OTCQB: NRXBF) (Germany: J90) (“

NurExone

” or the “

Company

”) is pleased to announce the formation of a U.S.-based subsidiary, Exo-Top Inc. (“

Exo-Top

”), that is expected to advance good manufacturing practice (“

GMP

”), fully characterized exosome production. The establishment of Exo-Top is a key step towards an independent and scalable supply of high-quality exosomes for the Company’s future nanodrug pipeline and collaboration opportunities following NurExone’s acquisition of a Master Cell Bank (“

MCB

”) of Mesenchymal Stem Cells (“

MSC

”).

Exosomes are increasingly recognized as a revolutionary drug delivery system with inherent therapeutic effects and capable of transporting therapeutic molecules - including ribonucleic acid, proteins, and small molecules - directly to target cells with high precision and minimal invasiveness.1 The exclusive MCB provides Exo-Top with a sustainable, cost-effective, and unique source of exosome-producing cells, a foundation for the production of fully characterized GMP-grade exosomes.

In addition to supporting NurExone’s internal drug development efforts, Exo-Top will be positioned to supply high-quality exosomes to other pharmaceutical companies, biotech firms, and researchers worldwide, opening additional revenue streams for the Company. By supplying GMP-grade exosomes for drug delivery research and existing, non-U.S. Food and Drug Administration (“FDA”)-regulated therapeutic or cosmetic applications, Exo-Top creates new market opportunities while advancing the broader adoption of MSC-based exosomes as a transformative drug delivery system and a potentially regenerative treatment via NurExone’s ExoTherapy platform.

The acquisition of the MCB and the formation of Exo-Top will give NurExone greater control over its exosome production process. Unlike companies that depend on third-party cell sources, Exo-Top will operate independently, without external licensing or royalty obligations, ensuring cost efficiency and strategic flexibility as NurExone advances its development pipeline.

Dr. Lior Shaltiel, CEO of NurExone commented: “exosomes are rapidly emerging as the next frontier in drug delivery and regenerative medicine, with the potential to transform treatments for neurological disorders, oncology, longevity and beyond. Establishing Exo-Top anchors our supply chain, accelerates our drug development, and creates business opportunities through exosome commercialization.”

Eran Ovadya, CFO of NurExone, added: “as part of our growth strategy, we also plan to pursue an uplisting from the OTC to a major U.S. exchange, subject to requisite regulatory approval, to strengthen our market position and broaden investor access.”

Exo-Top was established under the jurisdiction of the State of Nevada. Basing Exo-Top in the U.S. offers key advantages, including proximity to strategic partners, access to a robust biopharma ecosystem, and increased market opportunities.

The Company will provide further updates as it progresses with the formation and long-term production strategy of Exo-Top.

Forward-looking statements in this press release include, but are not limited to, statements relating to: the intended benefits of Exo-Top’s establishment and the acquisition of the MCB on the Company and its business; the Company advancing its revenue-generating and collaboration opportunities; the Company being able to produce, supply and commercialize exosomes; the Company’s products being used for patient treatment; broader adoption of exosomes in the field and cell therapy applications; the Company’s future plans and expectations; NurExone advancing its development pipeline; the Company’s plan to pursue an uplisting and the benefits thereof; receipt of all requisite regulatory approval; the Company providing further updates on Exo-Top; and the NurExone platform technology offering novel solutions to drug companies interested in minimally invasive targeted drug delivery for other indications.

These statements reflect management’s current beliefs and are based on information currently available to management as at the date hereof. In developing the forward-looking statements in this press release, we have applied several material assumptions, including: Exo-Top’s establishment and the acquisition of the MCB will have its intended benefits on the Company and its business; the Company will advance its revenue-generating and collaboration opportunities; the Company will be able to produce, supply and commercialize exosomes; the Company’s products will be used for patient treatment; there will be broader adoption of exosomes in the field and cell therapy applications; the Company will realize its future plans and expectations; the Company will uplist to a major U.S. exchange and realize on the benefits thereof; the Company will provide further updates on Exo-Top; the Company will receive all requisite regulatory approval; and the NurExone platform technology will offer novel solutions to drug companies interested in minimally invasive targeted drug delivery for other indications.

Forward-looking statements involve significant risk, uncertainties and assumptions. Many factors could cause actual results, performance or achievements to differ materially from the results discussed or implied in the forward-looking statements.
