[SCHEDULE 13G] Helix Acquisition Corp. II SEC Filing

Rhea-AI Filing Summary

Schedule 13G filing: Sculptor Capital LP and affiliated entities disclosed beneficial ownership of 967,460 Class A ordinary shares of Helix Acquisition Corp II (CUSIP G4444H101), representing 5.12 % of the 20 million shares outstanding as referenced in the issuer’s 10-Q filed 15 May 2025.

All voting and dispositive power over the shares is shared; none of the reporting persons has sole power. The stake is held across multiple accounts managed by Sculptor Capital LP and Sculptor Capital II LP, with control relationships flowing through Sculptor Capital Holding Corp and Sculptor Capital Management, Inc. The event triggering the filing occurred on 17 Jul 2025; the certification states the securities were acquired for passive investment, not to influence control of the issuer.

The filing identifies the reporting persons as investment advisers (IA) or control entities of such advisers. No other material transactions, financial results or changes in issuer control are disclosed.

Insights

Securities Analyst

TL;DR: Sculptor crosses the 5 % threshold, adding a new institutional holder; impact modest and informational rather than transformational.

Sculptor’s 967,460-share position triggers a Schedule 13G, signalling passive ownership. While this confirms professional investor interest, the size—5.12 % of outstanding—does not convey control and carries no stated activist intent. Because the filing provides no price data or strategic commentary, immediate valuation impact is limited. Investors may monitor future filings to see if Sculptor increases or decreases exposure, which could hint at evolving views on Helix Acquisition Corp II’s prospects.
