Amsterdam, Netherlands – May 12, 2026 -- Coincheck Group N.V. (NASDAQ: CNCK) (“Coincheck Group” or the “Company”) and KDDI Corporation (TYO: 9433) (“KDDI”) today announced they have entered into an agreement (the “Subscription Agreement”) pursuant to which KDDI, a telecommunications company with one of the largest customer bases in Japan, will invest in Coincheck Group, a Dutch public limited liability company that provides digital asset trade execution, custody, staking and asset management services. Concurrently with the signing of the Subscription Agreement, Coincheck Group’s Japanese subsidiary, Coincheck, Inc., entered into a business alliance agreement with KDDI focused on collaborative initiatives aimed at expanding the digital asset market in Japan, including through mutual customer referral programs and related revenue sharing and referral fees. By combining KDDI’s distribution reach and trusted consumer interfaces with Coincheck’s crypto asset platform and product expertise, the parties aim to reduce onboarding friction, broaden mainstream access to digital assets, and expand practical day-to-day use cases across KDDI’s ecosystem in Japan.

Under the Subscription Agreement, KDDI will subscribe for 28,536,516 newly issued Coincheck Group ordinary shares at a price of $2.28 per share, for an aggregate cash purchase price of $65,063,256.48 (the “Transaction”).

The Transaction is expected to close in June 2026. KDDI will receive registration rights for the acquired shares and will have the right to nominate one individual for appointment to the Company’s board, as a non-executive director, at Coincheck Group’s next Annual General Meeting, which is anticipated to be held in September 2026.

Pascal St-Jean, Coincheck Group’s Chief Executive Officer, commented: “We believe our partnership with KDDI is a clear signal of where our industry is headed – the convergence of traditional financial services and digital assets. Institutions of KDDI's stature are no longer asking whether to engage, but who they can trust to engage with at a large scale. KDDI's decision to make a significant strategic investment in Coincheck Group, alongside our commercial alliance, we think reflects that judgment. Coincheck Group has done the deliberate, disciplined work of building the regulatory standing, infrastructure, and institutional capability that makes us the platform of choice for partners of KDDI’s caliber. And we are excited about what this means for people in Japan — the opportunity for millions of consumers to gain easier, more-trusted access to digital assets through an institution they already know and rely on every day."

Shumpei Tatebayashi, Deputy General Manager, Open Innovation Division, of KDDI Corporation, commented: “We are pleased to announce this new chapter through our partnership with Coincheck Group, a global leader in digital asset technology, and Coincheck, Inc., which operates one of Japan’s largest digital asset exchanges. The digital asset landscape is evolving rapidly, driven by regulatory developments, technological innovation, and increasing public interest. As we move forward in this environment, we believe that ensuring safety and trust is just as essential as delivering convenience and innovation. This partnership represents an important milestone in our efforts to bring new, reliable, and trusted financial services to the Japanese market. By establishing a strong technical and business alliance, we are committed to accelerating the adoption of digital asset-based financial services and making them accessible and practical for everyone.”

Coincheck Group has been advised by J.P. Morgan, as financial advisor, and De Brauw Blackstone Westbroek and Simpson Thacher & Bartlett LLP, as legal counsel.
