4. Scope of business

The company’s mainstay business comprises the following 4 pillars:

The table below is based on the DMM.com Securities company profile, DMM CFD instrument page, and official DMM Banusy service display reviewed on 2026-07-29. Instrument counts are a snapshot of those pages, not permanent totals.^[Sources: https://securities.dmm.com/company/; https://fx.dmm.com/cfd/service/lineup/; https://banusy.dmm.com/.]

• Crypto-asset spot: none (handled by the separate legal entity DMM Bitcoin, but wound down in 2025-03 )
• Leveraged trading (crypto assets): listed by JVCEA, but crypto-asset instruments were not shown on the official CFD instrument page reviewed on 2026-07-29

• Staking / lending / NFTs: no offering was shown on the above official service pages reviewed on 2026-07-29
• Corporate services: no specific offering was identified on the above official service pages reviewed on 2026-07-29

5. Market share / trading volume

• Among the company and JVCEA materials identified in this review as of 2026-07-29, no account-count or monthly-volume disclosure for crypto-asset CFDs was identified. This does not establish that no such disclosure exists
• The capital-adequacy ratio of 421.6% as of March 2026 is a point-in-time figure from the official company profile; it does not establish market rank or the scale of crypto-asset CFD provision
• The JVCEA list identifies the company under crypto-asset-related derivatives. Do not freeze changing membership totals or assert a market rank without values using the same period and definition

6. History / major incidents

The table below is limited to registration, separate-entity relationships, and point-in-time financial facts confirmed through DMM.com Securities’ official profile and financial display, the JVCEA list, the National Police Agency notice on the DMM Bitcoin theft, and SBI VC Trade’s transfer notice. Rows about DMM Bitcoin do not describe an incident at DMM.com Securities.^[Sources: https://securities.dmm.com/company/; https://jvcea.or.jp/member/; https://www.npa.go.jp/bureau/cyber/koho/caution/caution20241224.html; https://www.sbivc.co.jp/newsview/1zkj8mf5x3y.]

Relationship to the wind-down of DMM Bitcoin (a separate legal entity):

DMM.com Securities’ official company profile lists it as a Type I and Type II Financial Instruments Business Operator and JVCEA member #1043. By contrast, the National Police Agency and SBI VC Trade identify the theft and customer-account transfer target as the separate legal entity DMM Bitcoin Inc.; SBI VC Trade gives 2025-03-08 as the transfer date for accounts and assets under custody. DMM Bitcoin’s spot-exchange wind-down must therefore not be conflated with termination of DMM.com Securities as a legal entity or registrant. The narrower group scope is nevertheless clear: DMM’s crypto-asset spot exchange ended while DMM.com Securities’ financial-instruments business continued separately. ^[Sources: https://securities.dmm.com/company/; https://www.npa.go.jp/bureau/cyber/koho/caution/caution20241224.html; https://www.sbivc.co.jp/newsview/273xz3k65.]

7. Strategic developments

• The official company and service pages reviewed on 2026-07-29 list FX, CFDs, equities, and the racehorse fund, while no crypto-asset CFD instruments appear in the current lineup.
• The same snapshot lists eight stock-index and 14 commodity-CFD instruments. Among the official materials identified in this review, no future crypto-asset CFD addition was identified, but this does not establish that no such plan exists.
• DMM Banusy remains listed as a business that differentiates the company’s product mix.
