Additional Proxy Soliciting Materials (Form DEFA14A)

On October 3, 2025, the board of directors of Tile Shop Holdings, Inc. (the "Board"), a Delaware corporation (the "Company"), upon the recommendation of the Independent Transaction Committee of the Board (the "Transaction Committee") consisting of independent directors, unanimously approved a "going dark" transaction whereby the Company would effect a reverse and forward stock split of the Company's common stock, par value $0.0001 per share (the "Common Stock") as further described below, in conjunction with delisting and registering the Common Stock from the Nasdaq Capital Market ("Nasdaq") and terminating the Company's public company reporting obligations (collectively, the "Transaction"), subject to obtaining the requisite approval of the Company's stockholders of the Reverse Stock Split at a special meeting of the Company's stockholders (the "Special Meeting"), which is currently expected to occur in December 2025.

Specifically, the Board approved , and recommend that the Company's stockholders approve, a reverse stock split of the Common Stock, at a ratio not less than 1-for-2,000 and not greater than 1-for-4,000 (the "Reverse Stock Split"), followed immediately by a forward stock split of the Common Stock at the same ratio but inverse (i.e., if the Reverse Stock Split were 1-for-2,000, then the Forward Stock Split would be 2,000-for-1) (the "Forward Stock Split," and together with the Reverse Stock Split, the "Stock Split"). Approval of the Reverse Stock Split requires the affirmative vote a majority of the votes cast (in person or by proxy) by the stockholders entitled to vote thereon. As a result of the Reverse Stock Split, each share of Common Stock held by a stockholder of record owning immediately prior to the effective time fewer than the minimum number of shares, which, depending on the Stock Split ratio chosen by the Board, would be between 2,000 and 4,000 shares (the "Minimum Number"), would be converted into the right to receive $6.60 in cash (the "Cash-Out Price"), without interest, and such stockholders would no longer be stockholders of the Company. Stockholders owning a number of shares of Common Stock equal to or greater than the Minimum Number immediately prior to the effective time of the Reverse Stock Split (the "Continuing Stockholders") would not be entitled to receive any cash for their fractional share interests resulting from the Reverse Stock Split, if any. The Forward Stock Split, which would immediately follow the Reverse Stock Split, would reconvert whole shares and fractional share interests held by the Continuing Stockholders back into the same number of shares of the Common Stock held by such Continuing Stockholders immediately prior to the effective time. As a result of the Forward Stock Split, the total number of shares of Common Stock held by a Continuing Stockholder would not change as a result of the Stock Split. The Company estimates that, based on a mid-point Reverse Stock Split ratio of 1-for-3,000, approximately 726.000 shares of Common Stock (or approximately 16% of the Common Stock currently outstanding) would be cashed out in the Transaction and the aggregate cost to the Company of the Transaction would be approximately $4.8 million, plus transaction expenses, which are estimated to be approximately $523,000.

The Cash-Out Price represents a premium above the Common Stock's closing price on October 2, 2025, and is supported by a fairness opinion delivered by GuideCap Partners LLC, whom the Transaction Committee engaged for such purpose. The Company intends to fund the Cash-Out Price using cash on hand together with borrowings under the Company's line of credit, if necessary.

The Transaction Committee and the Board each unanimously determined that it was advisable and substantively and procedurally fair to, and in the best interests of, the Company and its stockholders, that the Company pursue the delisting of the Common Stock from Nasdaq, the termination of the registration of  the Common Stock under Sections 12(d) and 12(g) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the suspension of the Company's duty to file periodic reports and other information with the U.S. Securities and Exchange Commission (the "SEC") under Section 13(a) thereunder. The Transaction Committee and the Board believe that the Company currently realizes none of the traditional benefits of public company status, yet incurs all of the significant annual expenses and indirect costs associated with being a public company.

Without its public company status, the Company would have an ongoing cost structure befitting its current and foreseeable scale of operations and its management would be able to have an increased focus on core operations. The purpose of the Reverse Stock Split is to (i) help the Company reduce and maintain the number of its record holders of its Common Stock below 300, which is the level at which the SEC public reporting obligations are required, (ii) offer liquidity to smaller stockholders at $6.60 per share without a brokerage commission (if applicable), and (iii) provide all stockholders the opportunity to vote on this matter.

Subject to the filing of the Company's proxy statement relating to the proposed Reverse Stock Split and stockholder approval thereof, it is anticipated that the Reverse Stock Split would become effective shortly after the Special Meeting. As of September 25, 2025, the Company's directors and executive officers owned approximately 36.9% of the issued and outstanding shares of Common Stock and are expected to vote "FOR" the approval of the Reverse Stock Split. The terms and contemplated timeline of the Reverse Stock Split, including the manner of determining the fair value for fractional share interests to be cashed out in the transaction, will be set forth in the preliminary proxy statement and a transaction statement on Schedule 13E-3 to be filed by the Company outlining the Transaction. The Transaction may be considered a "going private" transaction as defined in Rule 13e-3 promulgated under the Exchange Act, as it is part of a plan to terminate the registration of the Common Stock under Sections 12(b) and 15(d) of the Exchange Act and suspend the Company's duty to file periodic reports and other information with the SEC under Section 13(a) thereunder, and to delist the Common Stock from Nasdaq.

The Board also retained the right to abandon the Transaction, either before or after the vote of stockholders, if the Board determines that the Transaction is no longer in the best interests of the Company and its stockholders.

On October 6, 2025, the Company issued a press release announcing the Transaction. The press release is filed as Exhibits 99.1 to this Current Report on Form 8-K (this "Form 8-K") and is incorporated by reference herein.

The Company and its directors and executive officers may be deemed to be participants in the solicitation of proxies in connection with the proposed Transaction. Information concerning such participants will be set forth in the proxy statement for the Special Meeting, which will be filed with the SEC on Schedule 14A (the "Proxy Statement"). To the extent that holdings of the Company's securities change since the amounts printed in the Proxy Statement, such changes will be reflected on Statements of Change in Ownership on Form 4 or other filings filed with the SEC. Additional information regarding the interests of such participants in the solicitation of proxies in connection with the proposed Transaction will be included in the Proxy Statement.

Exhibit 99.1

Tile Shop's Board of Directors Approves Plan to Terminate Registration of Its Common Stock

MINNEAPOLIS, October 6, 2025 (GLOBE NEWSWIRE) - Tile Shop Holdings, Inc. (Nasdaq: TTSH) ("Tile Shop" or the "Company"), a specialty retailer of natural stone, man-made and luxury vinyl tiles, setting and maintenance materials and related accessories, today announced that the Independent Transaction Committee (the "Transaction Committee") of the Board of Directors of the Company (the "Board") comprised of independent directors has recommended, and the Board has approved, a plan to delist its shares of common stock from trading on the Nasdaq Capital Market, suspend its duty to file periodic reports and other information with the U.S. Securities and Exchange Commission (the "SEC"), and to terminate the registration of its common stock under the federal securities laws following the completion of a proposed reverse stock split. It is expected that this plan would be effectuated in December 2025, assuming the approval of Tile Shops' stockholders of the proposed reverse split at special meeting of the Company's stockholders (the "Special Meeting"), as described below.

The Company is taking these steps to avoid the substantial cost and expense of being a public reporting company and to focus the Company's resources on enhancing long-term stockholder value. The Company anticipates savings of approximately $2.4 million on an annual basis as a result of the proposed delisting and deregistration transaction.

The proposed reverse stock split will be at a ratio between 1-for-2,000 and 1-for-4,000, in which holders of shares of the Company's outstanding common stock in an amount less than the final determined reverse stock split ratio denominator would be cashed out at a price of $6.60 per share for their fractional shares. Such price represents a premium above the common stock's closing price on October 2, 2025 and is supported by a fairness opinion delivered by GuideCap Partners LLC ("GuideCap"), whom the Transaction Committee engaged for such purpose. Stockholders owning more shares of the Company's common stock than the reverse stock split ratio denominator prior to the reverse stock split would remain stockholders in the Company, which would no longer be encumbered by the expenses and distraction of a public reporting company. The number of shares they would own following the proposed transaction would be unchanged, as immediately after the reverse stock split a forward split would be applied to the continuing stockholders, negating any effects to them. The Company intends to fund the purchase of fractional shares resulting from the reverse stock split using cash-on-hand and, if necessary, with borrowings available under its line of credit.

The members of the Board determined unanimously that the proposed transaction is in the best interests of the Company and its stockholders. The Company currently realizes none of the traditional benefits of public company status, yet incurs all of the significant annual expenses and indirect costs associated with being a public company. Without its public company status, the Company would have an ongoing cost structure befitting its current and foreseeable scale of operations and its management would be able to have an increased focus on core operations. The purpose of the reverse stock split is to (i) help the Company reduce the number of its record holders of its common stock below 300, which is the level at which the SEC public reporting obligations are required, (ii) offer liquidity to smaller stockholders at $6.60 per share without a brokerage commission (if applicable) and (iii) provide all stockholders the opportunity to vote on this matter. Among the factors considered the Board were:

Subject to the filing of the Company's proxy statement relating to the proposed stock split and stockholder approval thereof, it is anticipated that the proposed transaction would become effective shortly after the Special Meeting of the Company's stockholders, which is expected to be held in December 2025.

Subject to receiving such stockholder approval, as soon as practicable after the Special Meeting of the Company's stockholders, the Company expects to delist its common stock from the Nasdaq Capital Market and terminate the registration of its common stock with the SEC. As a result, at such time, (i) the Company would cease to file annual, quarterly, current and other reports and documents with the SEC, except as otherwise required by the SEC, and stockholders would cease to receive annual reports and proxy statements, and (ii) the Company's common stock would no longer be listed on the Nasdaq Capital Market.
