CONTENTS

As previously disclosed on a Form 6-K by Brenmiller Energy Ltd., or the Company, on July 25, 2025 the Company entered into a securities purchase agreement, or the SPA, with Alpha Capital Anstalt, or Alpha, pursuant to which the Company agreed to issue and sell to Alpha, subject to certain conditions, up to an aggregate of $25 million in securities across multiple tranches, consisting of preferred shares, pre-funded warrants, and ordinary warrants. On July 28, 2025, an initial closing, or the PFW Closing, took place for a subscription amount of $1.2 million whereby the Company issued (i) pre-funded warrants to purchase 631,579 ordinary shares at an exercise price of $0.00001 per share, or the Pre-Funded Warrants, and (ii) ordinary warrants to purchase 631,579 ordinary shares at an exercise price of $2.09 per share, or the Ordinary Warrants.

On August 11, 2025, the Company and Alpha entered into an amendment to the SPA, or the Amendment, and agreed, among other things, to amend the aggregate subscription amount of the Pre-Funded Warrants and Ordinary Warrants in connection with the PFW Closing to $1,395,790.

The securities referred to herein were offered pursuant to an exemption from the registration requirements under Section 4(a)(2) of the Securities Act of 1933, as amended, or the Securities Act, and Rule 506(b) of Regulation D promulgated thereunder. The securities have not been registered under the Securities Act or applicable state securities laws. Accordingly, the securities may not be offered or sold in the United States except pursuant to an effective registration statement or an applicable exemption from the registration requirements of the Securities Act and such applicable state securities laws.

The foregoing summary of the Amendment does not purport to be complete and is qualified in its entirety by reference to the Amendment which is attached as Exhibit 10.1 to this Report of Foreign Private Issuer on Form 6-K, or the Report, and is incorporated herein by reference.
