[SCHEDULE 13D/A] lululemon athletica inc. SEC Filing

Rhea-AI Filing Summary

Amendment No. 10 to a Schedule 13D reports that Dennis J. Wilson and affiliated entities continue to beneficially own 9,973,547 shares of lululemon athletica inc., representing 8.4% of the company's common stock on a fully reported basis. The filing updates Item 4 to disclose that Mr. Wilson published a letter in The Wall Street Journal on 10/07/2025 expressing his views on the company's management and future, and incorporates that letter as an exhibit. The filing states the Reporting Persons may in the future engage with shareholders, officers, or directors about operations, governance, performance, and control. The cover pages were revised only to reflect a change in the issuer's outstanding share count used to calculate percentages.

Positive

• Clear disclosure of aggregate beneficial ownership: 9,973,547 shares (8.4%)
• Public communication (Wall Street Journal letter) increases transparency about holder views
• Structure detail provided for exchangeable shares and special voting stock improves investor understanding

Negative

• Potential governance pressure from a holder with 8.4% voting influence could lead to activism-driven change
• Public criticism in a widely read letter may create short-term reputational or stock volatility risks

Insights

Activist Investor

Large insider-aligned holder reiterates an 9.97M share position and signals active engagement.

The Reporting Persons together hold 8.4% of common stock, a sizeable minority stake that is explicitly tied to communications with management and other shareholders. That stake includes 4.76M exchangeable shares held by Anamered and 3.40M common shares held by LIPO, which shape voting power and economic exposure.

Engagement could range from public letters to private discussions; near-term items to watch include any follow-up communications, board responses, or proposals that could appear in the next 90-180 days.

Corporate Governance Analyst

Public letter and stated intent to engage raise governance and control considerations for shareholders.

The filing clarifies voting and dispositive arrangements: certain holdings are exchangeable shares paired with special voting stock that carry voting but not economic rights, affecting control mechanics without immediate cash transfer. The aggregate percentages use the issuer's reported capital structure of 113,468,082 common shares plus 5,115,961 special voting shares disclosed as of 08/29/2025.

Monitor whether communications trigger formal proposals, nominee disclosures, or amendments to voting arrangements during typical corporate notice periods for governance actions.

(b)	Name of Issuer: lululemon athletica inc.
(c)	Address of Issuer's Principal Executive Offices: 1818 Cornwall Avenue, Vancouver, BRITISH COLUMBIA, CANADA , V6J 1C7.
Item 1 Comment: This Amendment No. 10 (this "Amendment") is being filed by Dennis J. Wilson, Anamered Investments Inc. ("Anamered"), LIPO Investments (USA), Inc. ("LIPO"), Wilson 5 Foundation ("Wilson 5"), Wilson 5 Foundation Management Ltd. ("Wilson 5 Trustee"), Five Boys Investments ULC ("Five Boys"), Shannon Wilson, and Low Tide Properties Ltd. ("Low Tide") (collectively, the "Reporting Persons") and amends and supplements the Schedule 13D filed with the Securities and Exchange Commission by the Reporting Persons on February 14, 2019 (as amended, the "Schedule 13D") to reflect an update to Item 4 of the Schedule 13D. The Reporting Persons are filing this Amendment to amend Item 4 and Item 7 of the Schedule 13D to reflect statements made by Mr. Wilson in The Wall Street Journal on October 7, 2025. The number of shares of Issuer common stock beneficially owned by the Reporting Persons has not changed since the filing of Amendment No. 9 to the Schedule 13D filed by the Reporting Persons on August 11, 2025 and the cover pages and Item 5 of this Amendment have been amended solely to reflect a change in the number of shares of the Issuer's common stock outstanding as disclosed in the Issuer's most recent periodic report. The Items below amend the information disclosed under the corresponding Items in the Schedule 13D as described below. Capitalized terms used but not defined in this Amendment shall have the same meanings ascribed to them in the Schedule 13D. Except as specifically provided herein, this Amendment does not modify any of the information previously reported in the Schedule 13D
Item 4.	Purpose of Transaction
	Item 4 is hereby amended and supplemented as follows: On October 7, 2025, Mr. Wilson published the letter attached as Exhibit 4 to this Amendment in The Wall Street Journal, which sets forth his views on the Issuer, its management and its future. The information contained in Exhibit 4 of this Amendment is incorporated herein by reference. Each Reporting Person may in the future engage in communications, directly or indirectly, through public or private forums, with one or more shareholders of the Issuer, one or more officers of the Issuer and/or one or more members of the board of directors of the Issuer regarding the Issuer, including but not limited to its operations, prospects, stock performance, governance, management and control.
Item 5.	Interest in Securities of the Issuer
(a)	Item 5(a) is amended and restated in its entirety as follows: Anamered may be deemed to beneficially own 4,755,217 shares of the Issuer's common stock, or 4.0%. LIPO may be deemed to beneficially own 3,401,596 shares of the Issuer's common stock, or 2.9%. Each of Wilson 5 and Wilson 5 Trustee may be deemed to beneficially own 898,016 shares of the Issuer's common stock, or 0.8%. Five Boys may be deemed to beneficially own 91,760 shares of the Issuer's common stock, or 0.1%. Mrs. Wilson may be deemed to beneficially own 1,167,000 shares of the Issuer's common stock, or 1.0%. Low Tide may be deemed to beneficially own 554,122 shares of the Issuer's common stock, or 0.5%. Mr. Wilson may be deemed to beneficially own 9,973,547 shares of the Issuer's common stock, or 8.4%, including the shares held by the other Reporting Persons. The foregoing is based on 113,468,082 shares of the Issuer's common stock and 5,115,961 shares of the Issuer's special voting stock outstanding as of August 29, 2025 as disclosed by the Issuer in its Quaterly Report on Form 10-Q filed with the Securities and Exchange Commission on September 4, 2025. Each share of the Issuer's special voting stock has voting rights equivalent to one share of the Issuer's common stock, but no economic rights. Each share of the Issuer's special voting stock is paired with an exchangeable share (an "exchangeable share") of Lulu Canadian Holding, Inc., a wholly owned subsidiary of the Issuer ("Lulu Canada"). Holders of exchangeable shares may require Lulu Canada to redeem each of its exchangeable shares in exchange for one share of the Issuer's common stock plus a cash payment equal to any accrued and unpaid dividends on the exchangeable shares. When exchangeable shares are exchanged into shares of the Issuer's common stock, the Issuer cancels a corresponding number of shares of special voting stock without consideration. As a result, each exchangeable share, together with its paired share of special voting stock, may be deemed to represent beneficial ownership of one share of the Issuer's common stock.
(b)	Item 5(b) is amended and restated in its entirety as follows: The information set forth in Items 7, 8, 9, 10, and 11 of the cover pages to this Amendment is incorporated herein by reference. Anamered directly holds 4,755,217 exchangeable shares and an equal number of shares of the Issuer's special voting stock. LIPO directly holds 3,401,596 shares of the Issuer's common stock. Wilson 5 directly holds 898,016 shares of the Issuer's common stock. Five Boys directly holds 91,760 exchangeable shares and an equal number of shares of the Issuer's special voting stock. Mrs. Wilson directly holds 268,984 exchangeable shares and an equal number of shares of the Issuer's special voting stock. Low Tide directly holds 554,122 shares of the Issuer's common stock. Mr. Wilson directly holds 3,853 shares of the Issuer's common stock. Mr. Wilson may be deemed to have shared voting or dispositive power over the securities beneficially owned by Anamered, LIPO, Wilson 5, Wilson 5 Trustee, Five Boys. Mrs. Wilson, and Low Tide. Wilson 5 Trustee may be deemed to have shared voting or dispositive power over the securities beneficially owned by Wilson 5. Mrs. Wilson may be deemed to have shares voting or dispositive power over the securities that she holds directly as well as those beneficially owned by Wilson 5.
Item 7.	Material to be Filed as Exhibits.
