[SCHEDULE 13G/A] HEIDRICK & STRUGGLES INTERNATIONAL INC SEC Filing

Rhea-AI Filing Summary

Dimensional Fund Advisors LP reports ownership of 1,120,677 shares of common stock of Heidrick & Struggles International Inc, representing 5.4% of the class as of 09/30/2025. Dimensional discloses it provides investment advice to multiple registered funds and serves as manager or sub-adviser to commingled funds, group trusts and separate accounts that own the shares; all reported shares are held by those Funds and Dimensional expressly disclaims beneficial ownership.

The filing shows Dimensional has sole voting power over 1,093,291 shares and sole dispositive power over 1,120,677 shares. The Schedule 13G/A certifies the holdings were acquired in the ordinary course of business and not for the purpose of changing or influencing control of the issuer.

Positive

• Disclosure of a >5% stake (1,120,677 shares, 5.4%) provides transparency to investors
• Majority sole voting power alignment with dispositive power (1,093,291 votes vs 1,120,677 dispositive) simplifies governance expectations

Negative

• No indication of change-in-control intent limits insight into strategic intentions but also suggests passive ownership
• Holdings concentrated in Funds means underlying beneficial owners are not identified, reducing visibility into specific investor profiles

Insights

Institutional Ownership Analyst

Dimensional holds a passive >5% stake via managed Funds.

Holding 1,120,677 shares, or 5.4%, crosses the disclosure threshold that investors monitor for ownership concentration and potential voting influence. The split between voting power (1,093,291) and dispositive power (1,120,677) shows near-full alignment of voting and disposition within Dimensional's managed portfolios.

Risk depends on whether the Funds change position; the filing states holdings are in the ordinary course and not for control, which suggests passive intent. Investors may watch quarterly filings for material changes in the Q4 2025 timeframe.

Compliance & Proxy Specialist

Filing is a routine Schedule 13G/A with standard adviser disclaimers.

The statement clarifies that the securities are owned by client Funds and that Dimensional "disclaims beneficial ownership," consistent with advisory reporting practice. The signature by the Global Chief Compliance Officer attests that acquisitions were not intended to influence control.

Maintain attention to subsequent amendments or a shift to Schedule 13D if purpose or control intentions change; any such filing would be material and should be monitored on an ongoing basis.
