Insights

Financial Analyst

TL;DR: Capital Research holds a material 10.3% stake in Halliburton, a significant passive ownership position that investors should note.

Capital Research Global Investors reports beneficial ownership of 87.8 million Halliburton shares, or 10.3% of shares outstanding, with nearly all shares under sole voting and dispositive control. The Schedule 13G designation and the filers certification indicate the stake is held in the ordinary course of business and not for control. A >10% passive position is material from an ownership-concentration perspective and could affect liquidity and share-holder dynamics, but the filer disclaims an intent to influence control.

Corporate Governance Expert

TL;DR: A 10.3% passive stake triggers governance attention but the filer affirms no current intent to change control.

The filing documents sole voting power of 87,801,953 shares and sole dispositive power of 87,801,964 shares, which gives the filer clear ability to vote those shares at shareholder meetings. Because the filer used Schedule 13G (amendment) and certified ordinary-course holdings, this is presented as a passive investment rather than an activist campaign. Nevertheless, ownership above 10% is large enough to be a meaningful shareholder block in governance scenarios.
