[SCHEDULE 13D] TILE SHOP HOLDINGS, INC. SEC Filing

Rhea-AI Filing Summary

Fund 1 Investments, LLC disclosed a significant stake in Tile Shop Holdings, Inc. by reporting beneficial ownership of 12,859,012 shares, equal to approximately 28.8% of the outstanding common stock. The reporting person states the aggregate purchase cost was approximately $76,358,266, funded with the Funds' working capital.

The filer says the shares were acquired because they were believed to be undervalued and that it may engage with the Board and management about the company's proposed plan to delist and deregister following an expected special meeting in December 2025.

Positive

• Substantial ownership: direct beneficial ownership of 12,859,012 shares representing 28.8% of the class
• Significant capital commitment: aggregate purchase price of approximately $76,358,266, indicating investment conviction
• Intent to engage: plans to discuss the proposed Deregistration Plan and strategic/operational opportunities with the Board

Negative

• Deregistration/delisting risk: the company’s Board approved a plan to delist and deregister pending stockholder approval expected in December 2025
• Limited voting reach from derivatives: cash-settled swaps cover 902,113 notional shares (~2.0%) but provide no voting power
• Concentration risk: holding nearly 28.8% of shares creates exposure to share-price volatility and potential liquidity constraints

Insights

Activist Engagement Specialist

Large minority stake positions the investor to press governance and strategic changes.

The filing shows a 28.8% economic and voting stake through direct holdings, funded at an aggregate cost of $76,358,266, indicating a meaningful ownership position that typically justifies direct engagement with directors and management on strategy and corporate governance.

The investor explicitly intends to discuss the proposed deregistration/delisting plan and other strategic matters. Near-term items to monitor include the December 2025 special meeting outcome and any announced changes to Board composition or corporate actions within the following 1–3 months.

Capital Structure & Risk Analyst

Stake concentration and derivative exposure create both influence and certain economic risks.

The direct holdings equal 28.8% of outstanding shares while cash-settled swaps add economic exposure to roughly 2.0% more shares; the swaps do not confer voting rights, which limits total governance control to the directly held shares.

Key near-term risks include potential reduction in market liquidity if the Deregistration Plan proceeds and the investor’s concentrated position which could be affected by share-price moves or margin financing terms; watch for any disclosed financing changes or additional purchases over the next quarter.

Item 4.	Purpose of Transaction
	The Reporting Person purchased the Shares based on the Reporting Person's belief that the Shares, when purchased, were undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Person, and the availability of Shares at prices that would make the purchase or sale of Shares desirable, the Reporting Person may endeavor to increase or decrease its position in the Issuer through, among other things, the purchase or sale of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Person may deem advisable. On October 6, 2025, the Issuer announced that a committee of independent directors has recommended, and the Issuer's Board of Directors (the "Board") has approved, a plan to delist the Shares from trading on the Nasdaq Capital Market, suspend the Issuer's duty to file periodic reports and other information with the U.S. Securities and Exchange Commission, and to terminate the registration of the Shares under the federal securities laws following the completion of a proposed reverse stock split, assuming receipt of stockholder approval at special meeting of the Company's stockholders expected to be held in December 2025 (the "Deregistration Plan"). The Reporting Person intends to engage in discussions with the Board and the Issuer's management team regarding the Deregistration Plan, the Issuer's corporate governance and stockholder rights, and operational and strategic opportunities for the Issuer to enhance stockholder value (including following implementation of the Deregistration Plan, if approved by stockholders), among other matters. The Reporting Person does not have any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Person intends to review its investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer's financial position, results and strategic direction, actions taken by the Issuer's management team and the Board, price levels of the Shares, conditions in the securities markets, general economic and industry conditions, and other investment opportunities available to the Reporting Person, the Reporting Person may in the future take such actions with respect to its investment in the Issuer as it deems appropriate including, without limitation, engaging in additional communications with management and the Board, engaging in discussions with the Issuer, stockholders of the Issuer or other third parties about the Issuer and the Reporting Person's investment, including potential business combinations or dispositions involving the Issuer or certain of its businesses or assets, including transactions in which the Reporting Person may seek to participate and potentially engage in, making recommendations or proposals to the Issuer concerning changes to the capitalization, ownership structure, Board structure (including Board composition), or suggestions for improving the Issuer's financial and/or operational performance, purchasing additional Shares, selling some or all of its Shares, engaging in short selling of or any hedging or similar transaction with respect to the Shares, including swaps and other derivative transactions, or changing its intention with respect to any and all matters referred to in Item 4.

As of the date hereof, the Reporting Person beneficially owned 12,859,012 Shares, constituting approximately 28.8% of the outstanding Shares.

Item 6.	Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer
	The Reporting Person has entered into certain cash-settled total return swap agreements (the "Cash-Settled Swaps") with an unaffiliated third-party financial institution, which provide the Reporting Person with economic exposure to an aggregate of 902,113 notional Shares, representing approximately 2.0% of the outstanding Shares. The Cash-Settled Swaps provide the Reporting Person with economic results that are comparable to the economic results of ownership, but do not provide the Reporting Person with the power to vote or direct the voting or dispose of or direct the disposition of the Shares that are the subject of the Cash-Settled Swaps.
