Business Details

In December 2025, the company changed its trade name to NANO Holdings Co., Ltd. and formally launched its Strategic Investment Business (Nano Bridge Investment / Bio Bridge I). It is advancing the NANO MRNA business (clinical development of TUG1 ASO and RUNX1 mRNA) and the investment business (establishment of Nano Bridge Investment and formation of Bio Bridge I) in parallel. Revenue sources consist of two pillars: Cosmetic Raw Material Supply (for Albion) and royalty income from Comlex® Otic Solution. From April 2026, the company will transition to a holding company structure, with the drug discovery business split off and succeeded by NANO MRNA Co., Ltd.

Recent Overview

Transitioned to a holding company structure and formally launched the investment business, substantially expanding cash on hand through bond issuance

At the extraordinary general meeting of shareholders in December 2025, the company changed its trade name to NANO Holdings Co., Ltd. and formally launched its Strategic Investment Business. Proceeds of ¥2,475 million from the issuance of the 1st Series of unsecured bonds (limited to qualified institutional investors) and ¥1,221 million from stock issuance through the exercise of stock acquisition rights, among other factors, substantially expanded the cash balance at fiscal year-end to ¥4,910 million (up ¥3,713 million year on year). Effective April 1, 2026, the drug discovery business was spun off through an incorporation-type company split into NANO MRNA Co., Ltd., with the company transitioning to a holding company structure. As a subsequent event, the company resolved to make Luna RD Co., Ltd. (holder of PEG-free LNP technology) a subsidiary (acquisition price of ¥200 million, planned acquisition of 66.67% voting rights).

Key Products

product
TUG1 ASO (Recurrent Glioblastoma)

Jointly developed with Nagoya University. At AACR in April 2026, the final results of the Phase I trial (up to dose level 4) were reported, and the optimal dose was determined to be level 3 or below. No serious safety concerns were observed, and long-term SD (Unconfirmed PR) accompanied by tumor shrinkage was confirmed in one case. Submission of the clinical trial notification for the Phase Ib trial is planned around August 2026.

product
RUNX1 mRNA (Osteoarthritis of the Knee)

A clinical trial site opened in Australia in November 2025, and the Phase I trial began. The first patient was dosed in February 2026, and a total of three patients had been dosed by the end of the fiscal year under review. The company is working with local medical institutions to expand screening opportunities.

product
Comlex® Otic Solution 1.5% (ENT103)

Marketed by Theoria Pharma Co., Ltd. since June 2023. During the fiscal year under review, revenue of ¥84 million (¥84,598 thousand) was recognized following a review of the profit-sharing method due to a contract amendment.

product
Cosmetic Raw Material Supply (for Albion)

Supplies raw materials for Eclat Facture and the medicated whitening serum EXIA Brightening Immaculate Serum. Revenue for the fiscal year under review was ¥89 million (¥89,900 thousand).

platform
Strategic Investment Business (Nano Bridge Investment / Bio Bridge I)

Established Nano Bridge Investment Co., Ltd. (NBI), a dedicated investment subsidiary. In January 2026, NBI obtained Qualified Institutional Investor status and, together with SBI Shinsei Growth Capital, formed the NBI–SBISGC No.1 Investment Limited Partnership (Bio Bridge I). The company has entered into confidentiality agreements with dozens of companies, primarily private healthcare companies and corporate carve-out opportunities, and is advancing consideration of investments and business alliances.

Growth Drivers

  • Acceleration of out-licensing activities to pharmaceutical companies as the TUG1 ASO Phase Ib trial progresses (clinical trial notification submission planned for August 2026)
  • Accumulation of clinical data through the continuation of the RUNX1 mRNA Phase I trial in Australia (three patients dosed)
  • Strengthening of the mRNA and nucleic acid drug platform technology base through the acquisition of PEG-free LNP technology via the acquisition of Luna RD Co., Ltd.
  • Future capital gains from the investment business through Nano Bridge Investment (NBI) and the formation of Bio Bridge I
  • Establishment of a deal sourcing framework and construction of a Japan-U.S.-China investment platform through collaboration with the SBI Group and others
  • Improvement in the business environment for drug discovery and healthcare through expanded government policies to strengthen drug discovery capabilities
  • Reduced funding burden through R&D subsidy income (¥76 million for the fiscal year under review) and Australian R&D tax incentive refunds

Risks

  • A loss-making structure in which the main recurring operating revenue has not yet been established and R&D and SG&A expenses continue to be incurred (operating loss of ¥965 million for the fiscal year under review)
  • Increased interest-bearing debt from the issuance of the 1st Series of unsecured bonds (¥1,300 million in long-term bonds, ¥300 million in bonds scheduled for redemption within one year classified as current liabilities), and the resulting financial burden of interest expenses and bond issuance costs
  • Clinical trial delay risk (accelerating patient enrollment is a challenge for RUNX1 mRNA, and the Phase Ib trial plan for TUG1 ASO is still being formulated)
  • Risk that out-licensing does not materialize, leading to funding depletion if milestone and royalty income fail to arise
  • High uncertainty in the investment business's performance forecast, to the extent that disclosure is not feasible, with heavy dependence on external factors such as the number of investments and stock market conditions
  • High dependence on sales from Cosmetic Raw Material Supply (for Albion), creating customer concentration risk
  • A declining equity ratio, down from 68.2% to 59.9%, reflecting a rising trend in financial leverage due to the increase in outstanding bonds
  • Increased group management costs and organizational integration risk associated with the transition to a holding company structure and the business split
