[SCHEDULE 13D/A] lululemon athletica inc. Amended Major Shareholder Report

Rhea-AI Filing Summary

Dennis J. Wilson and related entities reaffirm their 8.4% beneficial stake in lululemon athletica inc., totaling 9,904,856 common shares, with no change in holdings from the prior amendment. The filing shows Wilson with 3,852 shares under sole voting and dispositive power and 9,901,004 shares under shared voting and dispositive power.

Affiliated entities, including Anamered Investments Inc., LIPO Investments (USA), Inc., Wilson 5 Foundation, Wilson 5 Foundation Management Ltd., Five Boys Investments ULC, Shannon Wilson and Low Tide Properties Ltd., each report separate beneficial amounts, contributing to the overall group position. Several additional reporting persons currently report zero beneficial ownership. This Amendment No. 15 also updates the stated purpose of the group’s involvement by incorporating a March 12, 2026 press release in which Wilson addresses potential CEO candidates, questions the Board’s fitness to support “visionary leadership,” and calls for meaningful Board refreshment, Board independence, innovation investment, and stronger support for internal talent development.

Insights

Governance and activism analyst

Stake unchanged; filing ramps up governance pressure via public CEO letter.

The reporting group, led by Dennis J. Wilson, continues to hold 9,904,856 lululemon common shares, representing 8.4% of the class. The amendment confirms there has been no change in beneficial ownership from the prior amendment.

The new element is Wilson’s March 12, 2026 press release, attached as an exhibit. It addresses potential CEO candidates and questions whether the current Board can support “visionary leadership,” while calling for meaningful Board refreshment, stronger independence, innovation investment and internal talent development.

This shifts focus from ownership levels to governance influence. While it does not itself alter control or economics, it signals heightened shareholder activism around Board composition and the CEO selection process. Future company communications and governance actions will show how the Board responds to these concerns.
