Insights

Financial Analyst

Orbis/Allan Gray report a 9.5% passive stake in IMAX; holdings are significant in size but filed as passive.

Orbis Investment Management Limited reports sole voting and dispositive power over 5,093,213 shares, and together with Allan Gray Australia the aggregate is 5,113,033 shares (9.5%) of IMAX. The use of Schedule 13G/A and the certification that holdings are in the ordinary course of business indicate a passive investment posture rather than an intent to influence control. For investors, the filing documents a materially large minority stake in the company but provides no indication of activist intentions or operational changes.

Corporate Governance Expert

A 9.5% disclosed stake is material; the filing classifies the holders as non-U.S. institutions filing under 13G (passive).

The filing explicitly classifies Orbis and Allan Gray as Non-U.S. Institutions equivalent to investment advisers and contains a certification that the securities "were not acquired and are not held for the purpose of or with the effect of changing or influencing the control" of IMAX. This legal posture under Schedule 13G/A limits immediate governance implications: the reporting persons are not declaring control intent. The disclosure, however, creates public visibility of a substantial investor position.
