Coincheck Reports Financial Results for Second Quarter of Year Ending March 31, 2027

AMSTERDAM--(BUSINESS WIRE)-- Coincheck Group N.V. (NASDAQ: CNCK) (“Coincheck Group” or the “Company”), a Dutch public limited liability company that provides digital asset trade execution, custody, staking and asset management services, today reported financial results for the second quarter of the fiscal year ending March 31, 2027 (“fiscal 2027”). References to “fiscal 2026” mean the fiscal year ended March 31, 2026. Financial Highlights: 1 Certain Year-Over-Year Highlights Total revenue for the second quarter of fiscal 2027 decreased 43%, to ¥75.5 billion ($480 million) from ¥133.1 billion ($846 million) in the second quarter of fiscal 2026. The decrease was driven mainly by a decrease in Marketplace Trading Volume, partially offset by an increase in Transaction revenue – Institutional and Investment management fees. Verified Accounts 2 increased 18%, to 2,868,544 as of September 30, 2026 from 2,421,080 as of September 30, 2025. Customer Assets 3 decreased 26%, to ¥876.9 billion ($5,577 million) as of September 30, 2026 from ¥1,189.2 billion ($7,563 million) as of September 30, 2025. Customer Assets decreased due primarily to the decline in the market price of certain crypto assets, including Bitcoin (BTC), Ether (ETH), and XRP. Assets Under Management (AUM) 4 were ¥148.8 billion ($946 million) as of September 30, 2026. Marketplace Trading Volume 5 decreased 56%, to ¥41.5 billion ($264 million) for the second quarter of fiscal 2027 from ¥94.7 billion ($602 million) for the second quarter of fiscal 2026. Fluctuations in Marketplace Trading Volume are usually driven by crypto-asset industry market volumes and conditions generally, and the size and level of trading activity at Coincheck specifically, as well as market-price fluctuations in the crypto assets frequently traded. Net loss was ¥4,136 million ($26.3 million) in the second quarter of fiscal 2027, compared to a net income of ¥355 million ($2.3 million) in the second quarter of fiscal 2026. The decrease was driven primarily by an impairment loss of ¥2,962 million ($18.8 million) related to the Company's Aplo subsidiary recorded in the second quarter of fiscal 2027 (see "Other Recent Highlights" below for more information concerning the Company's plans regarding Aplo), a decrease in Marketplace Trading Volume, and higher selling, general and administrative expenses, partially offset by a net tax benefit in the second quarter of fiscal 2027. Adjusted EBITDA 6 was a loss of ¥4,020 million ($25.6 million) in the second quarter of fiscal 2027, compared to Adjusted EBITDA of ¥1,486 million ($9.5 million) in the second quarter of fiscal 2026. The decrease in Adjusted EBITDA was due primarily to the impairment loss relating to Aplo and an increase in operating loss. ___________________________________ 1 References in this announcement to “¥” are to Japanese Yen and references to “U.S. Dollars” and “$” are to United States Dollars. Unless otherwise stated, Coincheck Group has translated U.S. Dollar amounts from Japanese Yen at the exchange rate of ¥157.250 per $1.00, which was the ¥/$ exchange rate reported by the Federal Reserve Bank of New York as of September 30, 2026. 2 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. These numbers are for Coincheck Inc.’s business (do not include Aplo or Next Finance Tech) and, beginning June 2026, include accounts opened under CaaS arrangements Coincheck Inc. has with third-party firms, which are subject to fee-sharing and other economic terms with such third-party firms. 3 Cryptocurrencies held for customers + fiat currency deposited by customers. This does not include NFTs or customer assets of Aplo, or of Next Finance Tech (if any). 4 Assets Under Management (AUM) refer to the assets under management of 3iQ, which was acquired by the Company effective March 1, 2026. 5 Marketplace Trading Volume for a specific period is the total value of all transactions completed through Coincheck’s marketplace platform. 6 Adjusted EBITDA is a non-IFRS financial measure; see “Non-IFRS financial measures” for definition and corresponding reconciliation below. Other Recent Highlights: Shift in Business Strategy Regarding Aplo’s European Prime Brokerage Offering. Aplo SAS is the Company’s Paris-based crypto prime brokerage subsidiary that serves institutional customers and is licensed under Markets in Crypto-Assets Regulation ("MiCA"). The Company acquired Aplo in October 2025, in large part based on the Company’s high opinion of Aplo’s institutional trading technology. The Company recently has (i) performed an evaluation of Aplo’s performance as an independent, small-sized crypto institutional brokerage in the European Union subject to MiCA rules, (ii) taken into account the potential value that institutional trading technology could provide if combined with the Company’s 3iQ subsidiary’s digital asset management technology and services (3iQ was acquired by the Company effective March 1, 2026), and (iii) considered how such an integration of institutional digital asset management and trading services could enable 3iQ to offer, consistent with the Company’s recent shift in its overall business strategy towards offering integrated institutional crypto products, a powerful and attractive separately managed account offering to institutional and high net worth investors globally (the “SMA Offering”). Accordingly, the Company is in the process of winding down Aplo’s operations in France, transferring Aplo’s technology and related intellectual property to 3iQ, and inviting approximately one-half of Aplo’s current team to join 3iQ to work to complete the development of, and then launch, the SMA Offering. 3iQ currently estimates a launch date in the first half of calendar 2027. This winding-down process will follow the plan for the orderly cessation of Aplo's operations in accordance with French law.

Non-IFRS financial measures EBITDA and Adjusted EBITDA In addition to the Company’s results determined in accordance with IFRS Accounting Standards, the Company presents EBITDA and Adjusted EBITDA, non-IFRS measures, because the Company believes they are useful in evaluating its operating performance. EBITDA represents net profit (loss) for the period before the impact of taxes, interest, depreciation, and amortization of intangible assets, and Adjusted EBITDA represents EBITDA, further adjusted by excluding transaction expenses and the non-cash expenses of (i) share-based compensation and (ii) change in fair value of warrant liability, which fluctuates quarter to quarter based on the Company’s share price. The Company uses EBITDA and Adjusted EBITDA to evaluate its ongoing operations and for internal planning and forecasting purposes and believes that EBITDA and Adjusted EBITDA may be helpful to investors because they provide consistency and comparability with past financial performance. However, EBITDA and Adjusted EBITDA are presented for supplemental informational purposes only, have limitations as analytical tools, and should not be considered in isolation or as a substitute for financial information presented in accordance with IFRS Accounting Standards. A reconciliation is provided below for each non-IFRS financial measure to the most directly comparable financial measure stated in accordance with IFRS Accounting Standards. Investors are encouraged to review the related IFRS Accounting Standards financial measures and the reconciliation of these non-IFRS financial measures to their most directly comparable IFRS Accounting Standards financial measures, and not to rely on any single financial measure to evaluate Coincheck Group’s business. Please see tables on the following pages for reconciliations of non-IFRS Accounting Standards financial measures.
