I3 Corporation Partners with Pronexus to Enhance IPO Preparation and Investor Relations

Strategic Partnership to Enhance IPO and IR Support



I3 Corporation, headquartered in Chuo-ku, Tokyo, has announced a strategic partnership with Pronexus, located in Minato-ku, Tokyo. This collaboration aims to provide robust support for companies preparing for an Initial Public Offering (IPO) as well as established public companies. The joint efforts will focus on enhancing internal frameworks for IPO prepping companies and developing effective Investor Relations (IR) strategies for listed firms.

Background of the Partnership


In recent years, the significance of establishing an IR framework and improving disclosure practices for public companies has intensified. Factors influencing this trend include the necessity for companies to manage capital costs and share prices strategically, alongside growing regulatory demands for structured IR systems among listed entities. Furthermore, changes in listing maintenance criteria in the Growth Market, requiring companies to achieve a market capitalization of over 10 billion yen within five years post-listing, underscore the importance of efficient and investor-aligned IPO preparations.

Pronexus brings vast experience in disclosure and IR support, having successfully assisted numerous publicly listed and IPO-preparing firms. In contrast, I3 specializes in streamlining IPO preparations through its cloud-based service, "Hajimeno IPO," while also guiding listed companies with insights from experienced IR officers. Prior to this partnership, both companies held multiple educational seminars on IR and IPO-related topics, fostering a collaborative approach to supporting companies in these sectors.

Advancing the Partnership


Through this partnership, I3 and Pronexus aim not just to host singular educational workshops but to create a sustainable framework where both parties can refer clients to each other. This system will enable them to provide one-stop services for both public companies and those preparing for IPOs. The partnership is expected to deepen their respective strengths further, enabling them to assist listed companies in establishing more highly regarded IR systems viewed favorably by investors.

Moreover, they will comprehensively prepare IPO-bound companies to enhance their internal management systems. This includes seamless support in building effective IR frameworks and crafting presentation materials aimed at post-IPO success. Their shared goal is to implement a holistic support structure that promotes long-term corporate value for both public enterprises and those gearing up for IPOs.
