[SCHEDULE 13G/A] TERADATA CORPORATION SEC Filing

Rhea-AI Filing Summary

Teradata Corp is the subject of a Schedule 13G/A reporting filings by Ameriprise Financial, Inc. and Columbia Management Investment Advisers, LLC disclosing institutional, passive holdings below 5% of the outstanding common stock. Ameriprise reports an aggregate 4,560,927 shares (about 4.8% of the class) with 3,084,858 shares of shared voting power and 4,560,927 shares of shared dispositive power. Columbia Management reports an aggregate 4,494,686 shares (about 4.7%) with 3,031,346 shared voting power and 4,494,686 shared dispositive power.

The filing notes that Ameriprise, as parent of Columbia Management, may be deemed to beneficially own the shares reported by Columbia but that each disclaims beneficial ownership. The signatory certifies the holdings were acquired and are held in the ordinary course of business and not for the purpose of influencing control of the issuer.

Insights

Securities Analyst

TL;DR: Two institutional filers report passive stakes just under 5%, indicating interest but not control.

Ameriprise and Columbia Management disclose holdings of 4.8% and 4.7% respectively, each recorded as shared voting and dispositive power. Because both positions are below the 5% threshold and are reported on Schedule 13G, the disclosures reflect passive investment intent rather than an intent to influence control. The parent–subsidiary relationship is disclosed, with Ameriprise incorporating Columbia's reported shares while both disclaim beneficial ownership. For investors, this is material as an ownership update but not a control event.

Corporate Governance Expert

TL;DR: Passive institutional ownership under 5% reduces governance impact but confirms notable shareholder presence.

The filing shows substantial institutional presence through shared voting and dispositive power but explicitly frames the holdings as passive and not acquired to change control. The disclosure of the parent-subsidiary relationship and the disclaimer of beneficial ownership are standard governance disclosures that clarify stewardship and voting arrangements. This does not trigger the stronger reporting or procedural consequences associated with activist or control-seeking positions.
