NYB Partnered with Nvidia, HP and Equinix to Build the World's Largest Natural Compound Library for AI Drug Discovery

SINGAPORE, Oct. 2, 2025 /PRNewswire/ -- The9 Limited (Nasdaq: NCTY) today announced that its Singapore investee company Nanyang Biologics Pte. Ltd. ("NYB"), together with its subsidiaries and affiliates, entered into a business combination agreement with RF Acquisition Corp II ("RFAI") (NASDAQ: RFAI), a publicly traded special purpose acquisition company, in a transaction that will result in NYB becoming a publicly listed company (the "Proposed Transaction"). Following the closing, the combined company (the "Combined Company") is expected to be listed on Nasdaq under the reserved ticker symbol "NYB".

The Proposed Transaction gives NYB approximately $1.5 billion in pre-transaction equity value. NYB's existing shareholders, including The9, will roll over 100% of the equity and retain a majority of the Combined Company's outstanding shares, while NYB will also designate a majority of the Combined Company's board of directors. The transaction has been approved by the Board of Directors of NYB and RFAI, and its closing is expected to be in the first or second quarter of 2026, subject to shareholders' approval and the satisfaction of customary closing conditions. Additional information about the Proposed Transaction, including a copy of the business combination agreement and investor presentation, will be provided in one or more Current Reports on Form 8-K to be filed by RFAI with the SEC.

Following the Proposed Transaction, NYB aims to accelerate the discovery of more effective drug molecules and identify active ingredients from natural sources for use in both pharmaceuticals and traditional medicine by utilizing its AI platform accelerating therapeutic discoveries.

In June 2025, NYB was crowned the 1st Prize Winner among over 700 regional startups in the SuperAI Genesis Startup Competition 2025, held at SuperAI Singapore, Asia's largest AI event. among over 700 regional startups

In August 2025, NYB entered into a Memorandum of Understanding with Nvidia, Hewlett Packard Enterprise and Equinix focusing on building the largest natural compound library in the world, developing scalable AI platforms for drug discovery, and creating secure, enterprise-grade infrastructure for healthcare innovation. AI-driven drug discovery requires large-scale molecular screening and cloud-based collaboration. Sovereign digital infrastructure, meaning that data is strictly protected and complies with national and regional regulatory requirements, is particularly important for drug development, as it involves a large number of highly sensitive scientific research information, such as biopharmaceutical data and molecular screening models.

NYB holds a growing portfolio of patents across its drug-candidate pipeline and proprietary nutraceuticals. NYB is developing first-in-class precision medicines for cancers caused by DNA damage repair (DDR) deficiencies and drug resistance. NYB's lead candidate, NB-A002, has achieved successful preclinical results. NB-A002 is the first therapy to target ILF2 (Interleukin Enhancer Binding Factor 2), a previously undruggable therapeutic target for cancer treatment. With millions of new cancer patients each year presenting DDR or Homologous recombination alterations — and no approved therapies available for patients who develop resistance to PARP inhibitors — NB-A002 represents a significant opportunity to expand the field of synthetic lethality in oncology.

NYB Chairman, Dr Roland Ong, commented on the plan going public and the collaboration with the world's top leaders in technology and innovation, " We are delighted to announce our combination with RFAI, marking an important milestone in NYB's journey. Public listing can definitely speed up our AI-driven drug discovery. It breaks through barriers that have long hindered the advancement of medicine, significantly reduced R&D time and costs while opening new opportunities for humanity to pursue longevity. Our proprietary DTIGN platform has mapped vast numbers of molecules and successfully identified promising candidates, strengthening the feasibility of a new era of drug development.

"Since we received our first funding from The9 in 2020, NYB's mission is to turn this hidden chemistry into therapies and wellness solutions. To achieve this, we have built one of the world's most diverse living libraries — already comprising over 50,000 unique organisms and their chemical compounds — and paired it with our proprietary AI platform, to uncover what was once invisible. This initiative also positions Singapore as a global hub where biodiversity meets artificial intelligence, and where hidden compounds are translated into breakthroughs for better healthcare, wellness, and everyday life."
