Ocean Power Technologies, Inc.

Item 1.01 Entry into a Material Definitive Agreement. Note Exchange Agreements On September 25, 2026, Ocean Power Technologies, Inc. (the “Company”) entered into exchange agreements (the “Exchange Agreements”) with each of the holders (the “Noteholders”) of its Series C-1 Convertible Notes issued in a registered offering on April 1, 2026 (the “Existing Notes”). Pursuant to the Exchange Agreements, on such date, the Noteholders exchanged their Existing Notes for an equivalent principal amount of Series D Convertible Notes (the “Series D Notes”) in reliance on the exemption from registration provided by Section 3(a)(9) of the Securities Act of 1933, as amended (the “Securities Act”). The Existing Notes were cancelled upon the issuance of the Series D Notes. The Series D Notes are substantially similar to the Existing Notes, except that the conversion price was reduced from $12.00 to $2.45, and an alternative conversion price equal to 93% of the lowest VWAP (as defined in the Series D Notes) of the Company’s common stock, par value $0.001 per share (the “Common Stock”), during the seven trading days prior to the applicable conversion date, as well as certain other conforming and administrative changes. The conversion price is subject to customary adjustments upon any stock split, stock dividend, stock combination, recapitalization or similar event. The Noteholders also agreed to begin any amortization payments otherwise due under the Series D Notes on January 1, 2027. The Series D Notes bear interest at an interest rate of 4.5% per annum except that upon the occurrence and during the continuance of an Event of Default (as defined in the Series D Notes), interest will accrue on the Series D Notes at an interest rate of 13% per annum. Unless earlier converted, the Series D Notes will mature on the eighteen-month anniversary of the date of issuance at a premium to 13% to the face value of the Series D Notes. No Series D Notes may be converted to the extent that such conversion would cause a holder of such Series D Note to become the beneficial owner of more than 4.99% of the then outstanding Common Stock, after giving effect to such conversion (the “Beneficial Ownership Cap”). However, a Noteholder, upon notice to the Company, may increase or decrease the Beneficial Ownership Cap, provided that the Beneficial Ownership Cap in no event exceeds 9.99% of the shares of Common Stock outstanding immediately after giving effect to such conversion. Any increase in the Beneficial Ownership Cap will not be effective until the sixty-first (61st) day after such notice is delivered to the Company. The Noteholders also may not convert any Series D Notes into a number of shares of Common Stock in excess of 19.99% of the outstanding shares of Common Stock as of the date of the Exchange Agreement until the Company obtains stockholder approval for such issuances in accordance with the applicable rules of the NYSE American. The foregoing descriptions of the Exchange Agreement and the Series D Notes are not complete and are qualified in their entirety by reference to the full texts of the forms of Exchange Agreement and the Series D Notes filed as Exhibits 10.1 and 10.2 hereto, respectively. Warrant Amendment Agreement On September 25, 2026, the Company also entered into an Amendment Agreement with each of the holders (the “Warrantholders”) of its common warrants issued on June 8, 2026 (the “Warrants”). Pursuant to the Amendment Agreement, the exercise price of the Warrants was adjusted from $12.00 to $2.45. The foregoing descriptions of the Amendment Agreement is not complete and are qualified in its entirety by reference to the full text of the form of Amendment Agreement filed as Exhibit 10.2 hereto.
