CONTENTS

Convertible Promissory Note and Warrant

 On May 10, 2026 (the “Issuance Date”), Nexera Technologies Ltd (the “Company” or “Nexera”) issued to an institutional investor (the “Holder”) a convertible promissory note (the “Fourth Promissory Note”) in the principal amount of $1,750,000 (the “Principal Amount”), for a purchase price in cash of $1,575,000 (equal to 90% of the Principal Amount). The Fourth Promissory Note was issued pursuant to the previously reported Securities Purchase Agreement, dated as of June 26, 2025 (the “SPA”), by and between the Company and the Holder, pursuant to which the Company may issue and sell, from time to time, convertible promissory notes (the “Promissory Notes”) in an aggregate principal amount of up to $100,000,000 (the “Subscription Amount”). The Company is not obligated to utilize any of the remaining Subscription Amount available under the SPA, which as of the date hereof is $90,750,000, and there are no minimum commitments or minimum use penalties.

On May 10, 2026, the Company entered into a second addendum to the SPA (the “Second Addendum”), pursuant to which the Company agreed to issue to the Holder, a warrant to purchase up to such number of Ordinary Shares representing 100% of the maximum number of Ordinary Shares issuable pursuant to the terms of the Promissory Note purchased by the Holder on May 10, 2026.

On May 10, 2026, Nexera issued to the Holder a warrant to purchase up to 1,119,098 Ordinary Shares (the “Warrant”), representing 100% of the maximum number of Ordinary Shares issuable pursuant to the Fourth Promissory Note. The Warrant was exercisable immediately upon issuance at an exercise price of $1.56376 per Ordinary Share (subject to certain anti-dilution and share combination event protections) and has a term of 5.5 years from the Issuance Date. The number of Ordinary Shares underlying the Warrant is subject to certain adjustments, as described in the Warrant.

The Company intends to use the net proceeds from the issuance of the Fourth Promissory Note and any additional net proceeds from the exercise of the Warrant, to the extent exercised in cash, for working capital and general corporate purposes.

The Fourth Promissory Note matures 28 months from the Issuance Date and is to be repaid, together with accrued and unpaid interest, in ten equal monthly payments, beginning on the eighteen month anniversary of the Issuance Date, unless earlier repaid (partially or in full) at the option of the Company, or extended at the option of the Holder in accordance with its terms. The Fourth Promissory Note accrues interest at annual rate of 4% (which will increase to 14% upon the occurrence and during the continuance of an event of default, as defined in the Fourth Promissory Note).

The Fourth Promissory Note is convertible (partially or in full) into the Company’s ordinary shares, no par value (the “Ordinary Shares”), at the option of the Holder, at any time after the Issuance Date, at a conversion price equal to the lower of (i) $1.73, which was the closing price of the Ordinary Shares on the Nasdaq Capital Market on May 8, 2026, the last trading day immediately prior to the Issuance Date (the “Fixed Price”), and (ii) 88% of the lowest daily volume weighted average price during the 20 consecutive trading days immediately preceding the applicable date of conversion (the “Variable Price”), provided that such Variable Price may not be lower than $0.346 per Ordinary Share (the “Floor Price”), which is equal to 20% of the Fixed Price; subject to certain adjustments as provided in the Fourth Promissory Note. The Holder’s option to convert the principal amount plus accrued and unpaid interest due under the Fourth Promissory Note at any time is subject to the limitation that the conversion may not result in the Holder’s beneficial ownership of Ordinary Shares after giving effect to such conversion exceeding 4.99% of the issued and outstanding Ordinary Shares.

The Fixed Price of any additional Promissory Notes to be issued pursuant to the SPA will be equal to the closing price of the Ordinary Shares on the Nasdaq Capital Market on the last trading day immediately prior to the date of issuance of such Promissory Note, and the Floor Price will be equal to 20% of such Fixed Price. Under the Addendum the Company also agreed that the Holder’s obligation to pay the purchase price for any additional Promissory Notes issued on or following May 10, 2026 shall be conditioned upon, and shall become due and payable upon, the Company’s filing of a resale registration statement with the Securities and Exchange Commission (the “SEC”) covering the resale of the Ordinary Shares issuable pursuant to such Promissory Note.

The exercise of the Warrant constitutes the Holder’s sole recourse against non-payment of the Principal Amount, Interest, and any Payment Premium (as defined in the Promissory Notes), if applicable, regardless of whether the aggregate value realized from the Warrant and/or the Ordinary Shares issued pursuant to the terms of the Fourth Promissory Note is less than the then outstanding Principal Amount, Interest, and, if applicable, the Payment Premium.

The Fourth Promissory Note and the Warrant were, and the Ordinary Shares issuable upon conversion or exercise, as applicable, thereof (the “Securities”) will be, issued pursuant to an exemption from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), and have not been, and will not be, registered under the Securities Act, or applicable state securities laws. Accordingly, the Securities may not be 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 law. Pursuant to the SPA and the Second Addendum, the Company has agreed to file a registration statement with the SEC to register the resale of the Ordinary Shares issuable upon conversion of the Fourth Promissory Note and upon exercise of the Warrant.

This Report of Foreign Private Issuer on Form 6-K (this “Form 6-K”) shall not constitute an offer to sell or the solicitation of an offer to buy the Securities, nor shall there be any sale of these Securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.

The descriptions of the Second Addendum, the Fourth Promissory Note and the Warrant set forth above do not purport to be complete and are qualified in their entirety by reference to the full text of those documents, which are attached hereto as Exhibits 10.1, 4.1 and 4.2, respectively.
