RYTHM, Inc.

The Green Thumb Note was amended on May 8, 2025 to issue pre-funded warrants in lieu of cash interest with 18,614 pre-funded warrants issued on May 8, 2025 and an additional 11,373 pre-funded warrants to be issued on September 1, 2025, replacing the previously defined cash interest payment dates. The number of pre-funded warrants is equal to the cash interest amount otherwise payable on the Green Thumb Note divided by the closing share price on May 8, 2025, which is the effective date of the amendment. No changes were made to the conversion price of the principal amount of the Green Thumb Note. The pre-funded warrants have an exercise price of $0.001 per share, will be exercisable upon issuance, will expire when the applicable warrant is exercised in full, and are exercisable on a cash basis or, if there is no effective registration statement registering the resale of the underlying shares of common stock, on a cashless exercise basis at the holder’s discretion. The pre-funded warrants and the shares of common stock underlying the pre-funded warrants (collectively, the “Securities”) were, and will be, offered and sold in transactions exempt from registration under the Securities Act in reliance on Section 4(a)(2) thereof and Rule 506(b) of Regulation D thereunder. The holder of the pre-funded warrants is an “accredited investor,” as defined in Regulation D, and is acquiring the Securities for investment only and not with a view towards, or for resale in connection with, the public sale or distribution thereof. Accordingly, the Securities will not be registered under the Securities Act and the Securities may not be offered or sold in the United States absent registration or an exemption from registration under the Securities Act and any applicable state securities laws.
