Insights

Institutional Ownership Analyst

Institutions collectively hold a meaningful passive stake of 10.02% in OTEX.

The combined position of 25,342,398 shares represents a sizeable minority stake that may affect liquidity and block-trade dynamics for large orders. Jarislowsky, Fraser's 21.15M-share position is the dominant component, accounting for the bulk of the group's ownership.

This filing states the stake is held in the ordinary course and not to influence control, so near-term governance change is not signaled. Investors may watch subsequent filings for any change in voting/disposition power or increases above common activist thresholds within 90 days.

Regulatory/Compliance Analyst

The Schedule 13G/A shows coordinated joint filing mechanics without an asserted control intent.

Signatures and exhibits (Joint Filing Agreement; Power of Attorney) indicate the four filers agreed to a joint filing structure, which aggregates their positions to report a combined 10.02%. Each filer separately reports sole voting and dispositive power over its shares.

Because the filing is made under Schedule 13G/A with certifications that holdings are passive, regulatory implications are limited; any future conversion to an active position would require a Schedule 13D and should be monitored on an ongoing basis.
