Insights

Equity Ownership Analyst

Amendment clarifies Ameriprise's passive, shared position in TETRA Technologies.

The Schedule 13G/A lists shared voting power 5,502,797 and shared dispositive power 5,515,522, equal to 4.1% of the class per the cover rows. The filing also disclaims beneficial ownership.

Because the report is passive and below activist thresholds, its immediate market significance is limited; subsequent disclosures would be needed to signal active intentions.

Corporate Governance Specialist

Report signals institutional holding but with disclaimers on control.

The filing attributes voting and dispositive powers to Ameriprise but expressly disclaims beneficial ownership, a common attribution when assets are held through client accounts or managed structures.

Beneficial ownership and control implications depend on underlying client mandates and are not resolved in this amendment.
