Insights

TL;DR: Routine disclosure clarifying business scope and metric definitions; no new financial results or material events disclosed.

The report is a standard Form 6-K update that reiterates Coincheck's role as a regulated crypto exchange in Japan and explains how it measures monthly activity and user/customer balances. Definitions for Exchange Trading Volume, Marketplace Trading Volume, Customer Assets, and Verified Accounts improve transparency for interpreting future monthly figures. Because the filing contains no revenue, volume figures, or operational changes, it has no immediate valuation implications.

TL;DR: Governance-appropriate disclosure of investor access points and metric definitions; no governance changes reported.

The filing emphasizes public availability of materials on the corporate website and opt-in email alerts, which supports investor communications practices. It cleanly separates Coincheck Group from operating subsidiary Coincheck, Inc., and clarifies measurement conventions (J-GAAP basis for customer assets, KYC for verified accounts). The disclosure is pro forma and does not report executive, structural, or regulatory developments.

Notes 
Exchange Trading Volume for a specific period is the total value, based on the underlying asset, of all transactions completed through Coincheck’s exchange platform. Coincheck’s exchange platform facilitates buy and sell transactions directly between two parties (a buyer and a seller) for which, generally, Coincheck charges no fee. Coincheck sometimes is a buyer on the exchange platform to help support transaction activity on the marketplace platform.
Marketplace Trading Volume for a specific period is the total value, based on the underlying asset, of all transactions completed through Coincheck’s marketplace platform business. Historically, Coincheck’s total revenue has been derived primarily from transactions on Coincheck’s marketplace platform business. For additional details, please see Coincheck Group N.V.’s filings with the U.S. Securities and Exchange Commission.
Customer Assets and Number of Verified Accounts correspond to figures as of the end of each month. Verified Accounts are all accounts that have been opened after the account owner completes all application procedures (including “know your customer” or “KYC”), after subtracting therefrom the total number of closed accounts.
Customer Assets are cryptocurrencies held for customers + fiat currency deposited by customers on a Japanese generally accepted accounting principles (J-GAAP) basis. Customer Assets do not include non-fungible tokens (NFTs).
Prior monthly numbers, which are generally preliminary at the time of initial publication, may have been updated by immaterial amounts.
