As previously reported, on December 15, 2025, Tile Shop Holdings, Inc. (the “Company”) effected a 1-for-3,000 reverse stock split (the “Reverse Stock Split”) of the Company’s common stock, par value $0.0001 (the “Common Stock”). As a result of the Reverse Stock Split, each stockholder of record owning fewer than 3,000 shares of Common Stock immediately prior to the effective time of the Reverse Stock Split became entitled to receive $6.60, without interest, in cash for each whole share of Common Stock held by such stockholder at the effective time of the Reverse Stock Split (the “Cashed-Out Stockholders”).

Following the completion of the Reverse Stock Split, the Company anticipates that it will pay an aggregate of approximately $32.0 million to the Cashed-Out Stockholders, including to stockholders holding through banks and brokers.
