Cautionary Statement Regarding Forward-Looking Statements This presentation contains “forward-looking statements” within the meaning of U.S. federal securities laws. These forward-looking statements relate to expectations for future financial performance, business strategies or expectations for our business. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. Forward-looking statements are typically identified by words such as “plan,” “believe,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “continue,” “could,” “may,” “might,” “possible,” “potential,” “predict,” “should,” “would” and other similar words and expressions, but the absence of these words does not mean that a statement is not forward-looking. These forward-looking statements are based on information available as of the date of this presentation and our managements’ current expectations, forecasts and assumptions, and involve a number of judgments, known and unknown risks and uncertainties and other factors, many of which are outside of our control. Accordingly, forward-looking statements should not be relied upon as representing our views as of any subsequent date. We do not undertake any obligation to update, add or to otherwise correct any forward-looking statements contained herein to reflect events or circumstances after the date they were made, whether as a result of new information, future events, inaccuracies that become apparent after the date hereof or otherwise, except as may be required under applicable securities laws. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this presentation. As a result of a number of known and unknown risks and uncertainties, actual results or performance may be materially different from those expressed or implied by these forward- looking statements. These risks and uncertainties include, but are not limited to, the price of crypto assets and volume of transactions on Coincheck’s platform; the development, utility and usage of crypto assets; changes in economic conditions and consumer sentiment in Japan; cyberattacks and security breaches on the Coincheck platform; demand for any particular crypto asset; adverse changes to any laws or regulations in the United States, Japan or the Netherlands or Coincheck’s failure to comply with any laws or regulations; administrative sanctions, including fines, or legal claims if we are found to have offered services in violations of the laws of jurisdictions other than Japan or to have violated international sanctions regimes; Coincheck’s ability to compete in a highly competitive industry; Coincheck’s ability to introduce new products and services; any interruptions in services provided by third-party service providers; the status of any particular crypto asset as a “security” in any relevant jurisdiction; legal, regulatory, and other risks in connection with our operation of the Coincheck NFT Marketplace that could adversely affect our business, operating results, and financial condition; our obligations to comply with the laws, rules, regulations, and policies of a variety of jurisdictions if we expand our international activities; the inability to maintain the listing of our Ordinary Shares on Nasdaq and other risk factors (the “Risk Factors”) discussed under "Item 3 - Key Information— D. Risk Factors" in the company's Shell Company Report on Form 20-F, filed with the U.S. Securities and Exchange Commission (SEC) on July 30, 2025.

All information set forth herein speaks only as of the date hereof. Forecasts and estimates regarding Coincheck’s industry and end markets are based on sources we believe to be reliable, however there can be no assurance these forecasts and estimates will prove accurate in whole or in part.

Non-IFRS Financial Measures This presentation includes certain financial measures not prepared in accordance with IFRS, which constitute “non-IFRS financial measures” as defined by the rules of the SEC. The non-IFRS financial measures are EBITDA and Adjusted EBITDA. We believe that EBITDA and Adjusted EBITDA enhance an investor’s understanding of our financial and operating performance from period to period, because by excluding certain items that may not be indicative of our recurring core operating results, we believe that EBITDA and Adjusted EBITDA provide meaningful supplemental information regarding our financial and operating performance. In addition, we believe EBITDA and Adjusted EBITDA are measures commonly used by investors to evaluate other companies in our industry. However, there are limitations to the use of these non-IFRS financial measures as analytical tools and they should not be considered in isolation or as a substitute for other financial measures calculated and presented in accordance with IFRS and may not be comparable to similarly titled non-IFRS measures used by other companies. 2 Disclaimer
