Item 1.01. Entry into a Material Definitive Agreement.

 

On June 30, 2025, Sonnet BioTherapeutics Holdings, Inc. (the “Company”) completed a sale to certain accredited investors of convertible notes in the aggregate principal amount of $2.0 million (the “Convertible Notes”) in an offering priced “at the market” under the rules of the Nasdaq Stock Market. In addition to the Convertible Notes, the investors also received warrants (the “Warrants”) to purchase an aggregate of 865,052 shares of common stock of the Company and received an aggregate of approximately $50,000 additional proceeds from the sale of the Warrants. The Warrants will be exercisable for five years at an exercise price of $1.156 per share.

 

The Convertible Notes bear no interest and will mature on June 30, 2026. The investors may elect to convert all or part of their Convertible Notes at any time into an aggregate of up to 1,730,104 shares of common stock of the Company at a conversion price of $1.156. Additionally, if at any time while the Convertible Notes remain outstanding, the Company issues shares of common stock or common stock equivalents in an offering for gross proceeds of at least $5.0 million (a “Subsequent Issuance”), the entire then unpaid principal amount of the Convertible Notes shall convert automatically into the same securities issued in the Subsequent Issuance upon the closing of the Subsequent Issuance. In the event a Subsequent Issuance does not occur within 90 days of the issuance of the Convertible Note, (i) the investors shall be entitled to purchase additional warrants with the same terms as the Warrants for up to 3,460,208 shares of common stock at a price of $0.25 per share of common stock and (ii) the Company shall file and use commercially reasonable efforts to have declared effective a registration statement for the Convertible Notes, the Warrants and the common stock issuable upon any conversion of the Convertible Notes or exercise of the Warrants.

 

Each investor agreed to restrict their ability to convert their Convertible Notes and exercise their Warrants to the extent that, after giving effect to such exercise or conversion, such investor would beneficially own in excess of 4.99%, 9.99% or 19.99%, as elected by each investor, of the then issued and outstanding shares of common stock of the Company.

 

The Convertible Notes and Warrants were sold in reliance upon an exemption from the registration requirement of the Securities Act of 1933, as amended, pursuant to Section 4(a)(2) thereof and/or Rule 506(b) of Regulation D promulgated thereunder.
