[SCHEDULE 13D/A] INSIGHT ENTERPRISES INC SEC Filing

Rhea-AI Filing Summary

The disclosure appears in Amendment No. 11 to a Schedule 13D and attributes shared voting and dispositive power across a group of related entities including ValueAct Capital Master Fund, L.P., VA Partners I, LLC and several ValueAct management and holdings entities. The filing states the source of funds as either "OO" or "WC" for the reporting persons and references an attached exhibit listing recent transactions. The statement is signed by Jason B. Breeding as authorized signatory on October 9, 2025.

Positive

• Consolidated reporting shows clear attribution of 2,101,739 shares across ValueAct entities
• Stake size of 6.7% is material enough to influence shareholder dialogue without constituting control

Negative

• No statement of intent regarding governance, strategic plans, or proposals was disclosed in this amendment
• Exhibit 1 (transactions) is referenced but not summarized here, limiting immediate transparency on timing and cost basis

Insights

Institutional Investor Analyst

ValueAct now holds a meaningful minority stake in Insight at 2,101,739 shares (6.7%).

Holding 2,101,739 shares and reporting shared voting/dispositive power indicates coordinated ownership across several ValueAct entities. At ~6.7%, this stake is large enough to warrant attention from management and other investors but is below typical control thresholds.

Risks include potential changes in stake size disclosed in subsequent filings; monitor the referenced exhibit for transaction timing and any further Schedule 13D amendments over the next weeks to months for changes to trading or intentions.

Corporate Governance Specialist

The filing documents shared voting and dispositive authority among related ValueAct entities, implying coordinated governance influence.

The Schedule 13D amendment describes overlapping ownership through managerial and GP/LP relationships among ValueAct affiliates, which commonly signals potential engagement with issuer governance or strategy without declaring specific plans here.

Investors should watch for subsequent disclosures of arrangements, proposals, or additional purchases; any formal engagement or agreement would typically appear in follow-up amendments or proxy filings within standard planning horizons.
