Insights

Securities Analyst

TL;DR Mizuho reports a material passive stake: 800,000 shares, or 9.0% of DT Cloud Star, with sole voting and dispositive power.

The filing documents a >5% holding that is significant enough to require Schedule 13G/A disclosure. The filer expressly certifies the position is held in the ordinary course of business and not to influence control, which aligns with the passive nature of a 13G filing. Recorded sole voting and dispositive power indicates Mizuho can vote and trade these shares without shared authority as reported.

Corporate Governance Expert

TL;DR Parent holding company disclosure names potential indirect ownership through a wholly-owned subsidiary and denies any intent to change control.

The statement identifies Mizuho Financial Group as a parent holding company and discloses that Mizuho Securities USA LLC may directly hold the equity, making Mizuho an indirect beneficial owner as described. The certification language explicitly states the securities were not acquired to influence control, which is material for governance analysis because it clarifies the filer’s stated intent and the regulatory posture of the ownership.
