[SCHEDULE 13G] Quartzsea Acquisition Corp SEC Filing

Rhea-AI Filing Summary

Wolverine Asset Management, LLC and affiliated entities reported collective beneficial ownership of 584,505 Ordinary Shares of Quartzsea Acquisition Corp, representing 5.12% of the outstanding class based on 11,409,900 shares outstanding as of 07/10/2025. The filing states the shares are managed by Wolverine Asset Management with shared voting and dispositive power of 584,505 shares and no sole voting or dispositive power. Wolverine identifies Wolverine Flagship Fund Trading Limited as a party with the right to receive dividends or sale proceeds for these shares. The filing certifies the securities were acquired in the ordinary course of business and not for the purpose of changing control.

Positive

• Transparent disclosure of beneficial ownership at the 5.12% threshold
• Consistent classification as an investment adviser/managed position (no sole control)

Negative

• Shared voting power only could limit the filer’s ability to influence corporate actions
• Concentration risk for funds receiving dividends/proceeds (Wolverine Flagship Fund Trading Limited)

Insights

Institutional Ownership Analyst

Wolverine group holds a meaningful passive stake of 5.12% in QSEA.

The group reports shared voting and dispositive power over 584,505 Ordinary Shares, equaling 5.12% of the class based on 07/10/2025 share count. Classification entries identify the filer as an investment adviser and related entities, indicating an advisory/managed position rather than a sole-control stake.

This holding crosses the common regulatory threshold that requires public disclosure and may attract attention from investors tracking ownership blocs; verify any future amendments if the position changes or if voting arrangements alter within the next 30–90 days.

Corporate Governance Specialist

Filing signals passive intent: shares were acquired in the ordinary course and not to affect control.

The certification explicitly states the shares "were not acquired and are not held for the purpose of or with the effect of changing or influencing the control of the issuer." Shared voting power is reported while sole power is zero, aligning with a managed, non‑controlling stake held on behalf of a fund.

Watch for any future Schedule 13D or amendments that would indicate an active intent; absent that, this position is consistent with advisory holdings and typical fund ownership profiles over the near term.
