Core Viewpoint - Rebio Biotech, established in 2007, is attempting to go public in Hong Kong after previously withdrawing its application for the Sci-Tech Innovation Board in 2020. Despite being recognized as a leader in the small nucleic acid drug sector, the company has yet to commercialize any self-developed drugs, relying heavily on financing and technology licensing for revenue [1][3]. Financial Performance - Rebio Biotech reported a revenue of RMB 44,000 in 2023, which is projected to increase to RMB 1.43 billion in 2024. However, net losses for the same periods were RMB 4.37 billion and RMB 2.81 billion, respectively, leading to a cumulative loss exceeding RMB 7 billion over two years [4][5]. - The company's total assets fluctuated from approximately RMB 7.16 billion in 2023 to RMB 10 billion in 2025, while total liabilities increased from RMB 6 billion to RMB 9.42 billion during the same period [5][6]. Funding and Financing - From 2015 to 2025, Rebio Biotech raised a total of RMB 1.829 billion from various investors, including Hillhouse Capital and CICC Capital. However, the company's valuation has been volatile, dropping from RMB 48.7 billion in 2024 to RMB 35.8 billion in 2025 [8][9]. - The company has been utilizing a combination of financing and business development (BD) partnerships to maintain operations, with significant contributions from collaborations, such as a deal with Qilu Pharmaceutical worth over RMB 700 million [9][11]. Research and Development - Rebio Biotech has developed a large pipeline of siRNA drugs, with six self-developed drug assets in clinical trials targeting various diseases. However, the company's resource allocation for core product development has been low, with only 19.1% to 25.9% of total R&D spending directed towards core products from 2023 to 2025 [12][14]. - The company has not established its own production facilities, relying on outsourcing for clinical sample production, which poses a challenge in the competitive landscape [16]. Market Position and Competition - The global small nucleic acid drug market is projected to grow from USD 2.7 billion in 2019 to USD 46 billion by 2033, with Rebio Biotech's core product, RBD4059, being the first siRNA drug for thrombotic diseases in clinical development. However, it faces competition from other companies that have advanced further in clinical trials [13][14].
