CONTENTS

On September 3, 2026, Polyrizon Ltd. (the “Company”), entered into a securities purchase agreement (the “Securities Purchase Agreement”) with investors for the purchase and sale of 232,500 of the Company’s ordinary shares, no par value per share (the “Ordinary Shares”) and 30,000 pre-funded warrants (the “RDO Pre-Funded Warrants”) to purchase up to 30,000 Ordinary Shares, in a registered direct offering (the “Registered Direct Offering”) at purchase price of $12.00 per Ordinary Share and $11.99999 per RDO Pre-Funded Warrant, respectively. The RDO Pre-Funded Warrants will be exercisable upon issuance at an exercise price of $0.00001 per Ordinary Share, subject to adjustment as set forth therein, and will not expire until exercised in full. The RDO Pre-Funded Warrants may be exercised on a cashless basis.

In a concurrent private placement (the “Private Placement” and together with the Registered Direct Offering, the “Offerings”), the Company also agreed to issue to the same investors a total of 70,833 pre-funded warrants (the “PIPE Pre-Funded Warrants” and together with the RDO Pre-Funded Warrants, the “Pre-Funded Warrants”) to purchase up to 70,833 Ordinary Shares and 333,333 ordinary share warrants to purchase up to 333,333 Ordinary Shares (the “Ordinary Share Warrants”). The PIPE Pre-Funded Warrants will be exercisable immediately (subject to registration) at an exercise price of $0.00001 per Ordinary Share, subject to adjustment as set forth therein, and will not expire until exercised in full. The PIPE Pre-Funded Warrants may be exercised on a cashless basis. The Ordinary Share Warrants will be exercisable upon issuance at an exercise price of $12.00 per Ordinary Share and will have a 5-year term from the issuance date.

A holder of the Ordinary Share Warrants and the Pre-Funded Warrants will not have the right to exercise any portion of its Ordinary Share Warrants or Pre-Funded Warrants if the holder (together with such holder’s affiliates, and any persons acting as a group together with such holder or any of such holder’s affiliates or any other persons whose beneficial ownership of Ordinary Shares would be aggregated with the holder’s or any of the holder’s affiliates), would beneficially own Ordinary Shares in excess of 9.99% of the number of the Ordinary Shares outstanding immediately after giving effect to such exercise.

The Offerings are expected to close on or about September 4, 2026, subject to the satisfaction of customary closing conditions. The aggregate gross proceeds to the Company are expected to be approximately $4.0 million. The Company expects to use the net proceeds from the Offerings, together with its existing cash, for general corporate purposes, which include financing our operations, capital expenditures and business development, technology development, and pursuing strategic opportunities, including but not limited to, strategic acquisitions.

The Securities Purchase Agreement also contain representations, warranties, indemnification and other provisions customary for transactions of this nature. In addition, pursuant to the Securities Purchase Agreement, the Company agreed to abide by certain customary standstill restrictions for a period of thirty (30) days following the effectiveness of a resale registration statement (the “Resale Registration Statement”) providing for the resale of the Ordinary Shares issuable upon the exercise of the PIPE Pre-Funded Warrants and the Ordinary Share Warrants (the “Release Date”), subject to permitted exceptions. The Company also agreed not to effect or agree to effect any Variable Rate Transaction (as defined in the Securities Purchase Agreement) for a period of sixty (60) days following the Release Date, subject to permitted exceptions.

In connection with the Private Placement, the Company entered into a registration rights agreement with the Purchasers on September 3, 2026 (the “Registration Rights Agreement”), pursuant to which the Company is required to file the Resale Registration Statement within 15 calendar days of the closing of the Private Placement.

The Company also entered into a letter agreement (the “Placement Agent Agreement”) with Aegis Capital Corp., as sole placement agent (the “Placement Agent”), dated September 3, 2026, pursuant to which the Placement Agent agreed to serve as the placement agent in connection with the Offerings. The Company agreed to pay the Placement Agent a cash placement fee equal to 8.0% of the gross proceeds received in the Offerings and $75,000 for reasonable legal fees and disbursements for the Placement Agent’s counsel.

The securities described above and to be issued in the Registered Direct Offering are being issued pursuant to a prospectus supplement dated as of September 3, 2026, which will be filed with the Securities and Exchange Commission, in connection with a takedown from the Company’s shelf registration statement on Form F-3 (File No. 333-291368) (the “Registration Statement”), which became effective on December 3, 2025, and the base prospectus dated as of December 3, 2025 contained in such Registration Statement. The securities offered in the concurrent Private Placement are being offered pursuant to the exemption provided in Section 4(a)(2) under the Securities Act of 1933, as amended, and/or Regulation D promulgated thereunder, and they are not being offered pursuant to the shelf registration statement. This Report on Form 6-K (this “Report”) shall not constitute an offer to sell or the solicitation to buy, nor shall there be any sale of, any of the securities described herein 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.
