Under the terms of the subscription agreement, KDDI will purchase 28,536,516  
newly issued ordinary shares of Coincheck at a price of $2.28 per share. The  
transaction, totaling just over $65 million in cash, is slated to close in  
June 2026\. Following the closure, KDDI will hold registration rights for the  
newly acquired shares and will be entitled to nominate one non-executive  
director to Coincheck Group’s board. The board appointment is expected to take  
place at the company’s Annual General Meeting in September 2026.

Concurrently, Coincheck’s Japanese subsidiary, Coincheck, Inc., executed a  
formal business alliance with KDDI. The operational partnership is designed to  
leverage KDDI’s extensive consumer distribution network to integrate Coincheck’s  
crypto trading, custody, and staking infrastructure. The companies outlined  
plans for mutual customer referral programs, shared revenue models, and  
initiatives intended to reduce friction in user onboarding for digital assets.

Coincheck Group CEO Pascal St-Jean characterized the partnership as an indicator  
of the ongoing convergence between traditional financial institutions and the  
digital asset sector, noting that the telecom’s investment validates Coincheck's  
regulatory and institutional infrastructure.

Representing KDDI, Shumpei Tatebayashi, Deputy General Manager of the Open  
Innovation Division, stated that the alliance will focus on pairing  
technological innovation with the safety and trust required to bring new  
financial services to Japanese consumers.
