Closing of Second Tranche Debt Financing

As previously reported on a Form 6-K filed with the U.S. Securities and Exchange Commission (the “Commission”) on May 26, 2026 (the “Prior Form 6-K”), the Company previously entered into the Agreement with the Investor to provide for loans in the aggregate amount of up to $3.5 million, under two tranches, of which the Investor previously funded to the Company an initial tranche of $1.0 million (net of original issue discount of $150,000) (the “First Tranche”) on May 7, 2026. The closing of the First Tranche consisted of the issuance and sale to the Investor, in a private placement, of a convertible promissory note in the aggregate principal amount of $1.165 million (the “Initial Note”) which is convertible into ordinary shares of the Company, no par value, (the “Ordinary Shares”), at a conversion price equal to 93% of the lowest daily volume weighted average price during the five trading days preceding the applicable measurement date, subject to certain adjustments.

On June 26, 2026, the Company, having met each of the closing conditions of the Second Tranche under the Agreement, including the receipt by the Company of the Shareholder Approval, to the satisfaction of the Investor, closed on the Second Tranche, pursuant to which the Company received proceeds of $2.5 million (net of original issue discount of $375,000). In consideration for the Investor’s funding of the Second Tranche, on June 26, 2026, the Company issued and sold to the Investor, in a private placement, of a second convertible promissory note (the “Second Tranche Note”) in the principal amount of $2.875 million which is convertible into Ordinary Shares at a conversion price equal to 93% of the lowest daily volume weighted average price during the five trading days preceding the applicable measurement date, subject to certain adjustments, subject to certain adjustments.

Except with respect to the certain expenses amount paid in connection with the closing of the Initial Note, the terms of the Second Tranche Note are substantially similar to the terms of the Initial Note issued in the First Tranche, which are summarized in the Prior Form 6-K. For more information about the terms of the Agreement, including the terms of the Initial Note, please see the Prior Form 6-K.
