Research Alliance V

We are a newly organized blank check company incorporated on April 1, 2026, as a Cayman Islands exempted company incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses, which we refer to throughout this prospectus as our initial business combination. While we may pursue an acquisition opportunity in any business, industry, sector or geographical location, we intend to focus on industries that complement our management team’s background, and to capitalize on the ability of our management team to identify and acquire a business, focusing on the healthcare or healthcare-related industries. In particular, we are targeting companies in the drug development and commercialization, diagnostic and healthcare technology and service sectors where our management has extensive investment experience. Our sponsor is an affiliate of RA Capital Management, a leading life sciences-focused investment firm with over $15 billion of regulatory assets under management as of December 31, 2025.
