Insights

Portfolio Manager

TL;DR – Vanguard discloses 12.43 % passive stake, adding solid institutional ownership without activist intent.

Vanguard’s 9.57 M-share position confirms a sizeable, long-term investment in Gartner. Although it holds no sole voting power, its dispositive authority over 9.2 M shares gives it flexibility to rebalance while signalling confidence in Gartner’s prospects. The passive nature (Rule 13d-1(b)) means minimal governance pressure but stable capital support, typically viewed favorably by the market.

Corporate Governance Specialist

TL;DR – Large stake but negligible voting rights; governance impact remains limited.

Despite owning 12.43 % of Gartner, Vanguard controls votes on only 102,210 shares, roughly 1 % of its position. This structure, common for index managers, suggests the holding is economic rather than strategic. As such, board influence or policy shifts are unlikely from this shareholder, maintaining the status quo in governance dynamics.
