Item 1.01 Entry into a Material Definitive Agreement.

As previously disclosed, on January 28, 2025, Interactive Strength Inc. (the “Company”) entered into that certain securities purchase agreement (the “Purchase Agreement”) with an accredited investor (the “Investor”). Pursuant to the Purchase Agreement, among other securities sold as disclosed in the Current Report on Form 8-K filed on February 3, 2025 (the “February 3rd 8-K”), as amended by an Current Report on Form 8-K/A filed on March 7, 2025 (the “March 7th 8-K/A”), the Company sold and the Investor agreed to purchase, Class A incremental warrants (the “Class A Incremental Warrants”) to purchase (a) senior secured convertible notes (the “Class A Incremental Notes”) in the aggregate principal amount of $13,000,000 and (b) warrants (the “Class A Incremental Common Warrants”) to purchase an aggregate of 269,710 (giving effect to the June 27, 2025 1 for 10 reverse stock split (the “Reverse Split”)) shares of the Company’s common stock, par value $0.0001 per share (“Common Stock”).

As previously disclosed, on March 11, 2025, the Investor elected to exercise Class A Incremental Warrants to purchase Class A Incremental Notes for an aggregate principal amount of $4,000,000 and, as a result, was issued Class A Incremental Common Warrants to purchase an aggregate of 82,988 shares of Common Stock (giving effect to the Reverse Split).

On July 25, 2025, the Investor elected to exercise Class A Incremental Warrants (the “Warrant Exercise”) to purchase Class A Incremental Notes for an aggregate principal amount of $3,000,000 and, as a result, was issued Class A Incremental Common Warrants to purchase an aggregate of 304,428 shares of Common Stock.

Description of the Class A Incremental Notes

The maturity date of the Class A Incremental Notes issued pursuant to the Warrant Exercise is July 25, 2028 (the “Maturity Date”).

The Class A Incremental Notes are convertible (in whole or in part) at any time prior to the Maturity Date into the number of shares of Common Stock equal to (x) 110% of the sum of (i) the portion of the principal amount of the Class A Incremental Note to be converted or redeemed, (ii) accrued and unpaid Interest with respect to such principal amount of the Class A Incremental Note, (iii) the Make-Whole Amount (as defined in the Class A Incremental Note), (iv) accrued and unpaid Late Charges (as defined in the Class A Incremental Note) with respect to such principal amount of the Note, Make-Whole Amount and Interest, and (v) any other unpaid amounts pursuant to the transaction documents, if any, divided by (y) a conversion price of $5.42 per share, subject to adjustment as provided in the Class A Incremental Note (such shares, the “Class A Incremental Note Conversion Shares”).

Description of the Class A Incremental Common Warrants

The Class A Incremental Common Warrants are exercisable for shares of Common Stock at a price of $12.46 per share (the “Class A Incremental Common Warrant Exercise Price”). The Class A Incremental Common Warrants issued pursuant to the Warrant Exercise may be exercised during the period commencing July 25, 2025 and ending July 25, 2032. The Class A Incremental Common Warrant Exercise Price is subject to customary adjustments for stock dividends, stock splits, issuances of additional shares of Common Stock and the like.

Pursuant to the terms of the Class A Incremental Notes and the Class A Incremental Common Warrants, the Company shall not effect the conversion of any portion of the Class A Incremental Notes or exercise of the Class A Incremental Common Warrants, to the extent that after giving effect to such conversion or exercise, as applicable, the Investor would beneficially own in excess of 4.99% (or, at the option of the Investor, 9.99%) of the shares of Common Stock outstanding immediately after giving effect to such conversion. On March 11, 2025, the Company obtained stockholder approval to issue up to (a) 10,242,324 shares of Common Stock (giving effect to the Reverse Split) pursuant to conversions of Class A Incremental Notes and (b) 684,647 shares of Common Stock (giving effect to the Reverse Split) pursuant to exercises of Class A Incremental Common Warrants.

The form of the Class A Incremental Warrant was filed as Exhibit 4.3 to the February 3rd 8-K. The Class A Incremental Notes have substantially the same form as the senior secured convertible note issued by the Company on January 28, 2025 which was filed as Exhibit 4.1 to the February 3rd 8-K. The Class A Incremental Common Warrants have substantially the same form as the warrants to purchase up to an aggregate of 67,427 shares of Common Stock (giving effect to the Reverse Split) issued by the Company on January 28, 2025 which was filed as Exhibit 4.1 to the March 7th 8-K/A.

Item 3.02 Unregistered Sales of Equity Securities.

Information set forth in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 3.02.

The Class A Incremental Notes and the Class A Incremental Common Warrants were offered and sold pursuant to an exemption from the registration requirements under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”) and Rule 506 of Regulation D promulgated thereunder or, in the event of an issuance of the Class A Incremental Note Conversion Shares or the shares of Common Stock underlying the Class A Incremental Common Warrants on a cashless basis, pursuant to the exemption provided in Section 3(a)(9) under the Securities Act.

The Investor is an “accredited investor” as that term is defined in Rule 501 under the Securities Act. The securities described in this Current Report on Form 8-K have not been registered under the Securities Act and may not be offered or sold in the United States in the absence of an effective registration statement or exemption from the registration requirements of the Securities Act. This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state.

Item 5.08 Shareholder Director Nominations.

Since the date of the 2025 Annual Meeting is more than 30 days after the anniversary of the date of the Company’s 2024 Annual Meeting of Stockholders, the Company is filing this Current Report on Form 8-K to inform stockholders of this change and to provide the due date for the submission of any qualified stockholder proposals or qualified stockholder director nominations.

Any such proposal must also meet the requirements set forth in the rules and regulations of the Securities and Exchange Commission in order to be eligible for inclusion in the proxy materials for the 2025 Annual Meeting.

In addition, in accordance with the requirements contained in the Company’s bylaws, stockholders of the Company who wish to bring business before the 2025 Annual Meeting outside of Rule 14a-8 of the Exchange Act or to nominate a person for election as a director must ensure that written notice of such proposal (including all information specified in the Company’s bylaws) is received by the Company’s Secretary at the Company’s principal executive offices no later than the close of business on August 5, 2025.
