Rhea-AI Filing Summary

Maple Rock Capital Partners Inc. and Xavier Majic report beneficial ownership of 10,430,818 common shares of Algoma Steel Group Inc., representing 9.9% of the outstanding class based on 104,933,802 shares. The filing amends prior Schedule 13D disclosures and is submitted on Schedule 13G under Rule 13d-1(h), indicating the reporting persons state the shares are held in the ordinary course of business and not to change or influence control. Maple Rock Master Fund LP is identified as the client with economic interest; Mr. Majic is CIO of the adviser.

Positive

• Disclosure of a 9.9% stake provides clarity on significant ownership in Algoma Steel
• Conversion to Schedule 13G signals the holders assert passive, ordinary-course investment intent

Negative

• Position size is material at 9.9% and could still affect market dynamics despite passive filing

Insights

Financial Analyst

TL;DR: A near-10% stake disclosed; filing as 13G signals passive intent but still represents substantial minority ownership.

The reporting persons hold 10,430,818 shares, or 9.9% of Algoma Steel's common shares, a size that can influence market perception and trading liquidity despite a declared passive position under Rule 13d-1(h). The amendment converting prior 13D disclosures to a 13G suggests a change from active strategic intentions to ordinary-course/ investment-adviser ownership. Investors should note the position size relative to total outstanding shares (104,933,802) as it remains a material minority stake in the capital structure.
