Management Comments

• "On January 12, 2026, The Vanguard Group, Inc. went through an internal realignment. In accordance with SEC Release No. 34-39538 (January 12, 1998), certain subsidiaries or business divisions of subsidiaries of The Vanguard Group, Inc., that formerly had, or were deemed to have, beneficial ownership with The Vanguard Group, Inc., will report beneficial ownership separately (on a disaggregated basis) from The Vanguard Group, Inc. in reliance on such release."
• "These subsidiaries and/or business divisions pursue the same investment strategies as previously pursued by The Vanguard Group, Inc. prior to the realignment."
• "The Vanguard Group, Inc. no longer has, or is deemed to have, beneficial ownership over securities beneficially owned by such subsidiaries and/or business divisions."
• "The securities referred to above were acquired and are held in the ordinary course of business and were not acquired and are not held for the purpose of or with the effect of changing or influencing the control of the issuer of the securities."

Industry Context

StockSavvy.ai notes that this internal realignment by The Vanguard Group reflects a trend among large asset managers to optimize reporting structures, potentially for regulatory compliance, operational efficiency, or to better reflect the independent investment mandates of various sub-entities. This disaggregation allows for clearer attribution of beneficial ownership to specific funds or divisions, which can be important for transparency and avoiding aggregation thresholds.

Comparison to Industry Standards

• This filing is a standard regulatory disclosure for changes in beneficial ownership, aligning with SEC requirements for institutional investors.
• The disaggregated reporting approach is consistent with practices seen in other large asset management firms like BlackRock or State Street, where various funds and sub-advisors may report their holdings independently, even if under a common parent.
• The stated purpose of holding securities in the ordinary course of business, without intent to influence control, is a common declaration for passive institutional investors.

Stakeholder Impact

• Shareholders (AMG): No direct impact on AMG's operations or financial performance. The change is in who reports ownership, not necessarily who holds the shares in aggregate across Vanguard's ecosystem.
• Investors (Vanguard funds): The underlying investment strategies pursued by Vanguard's subsidiaries remain the same, ensuring continuity for fund investors.

Next Steps

• Vanguard's subsidiaries or business divisions will now report their beneficial ownership in Affiliated Managers Group Inc. separately.

Key Dates

Recommendation

This Schedule 13G amendment primarily details an internal organizational and reporting change by The Vanguard Group, resulting in their direct beneficial ownership in Affiliated Managers Group Inc. being reported as zero. It does not reflect a change in investment strategy for AMG, nor does it provide new financial or operational data for AMG. Therefore, a "hold" recommendation is appropriate as the filing itself does not present new information that would warrant a change in investment stance for AMG. The underlying investment strategies of Vanguard's disaggregated entities are stated to remain the same.
