Item 3 is amended and restated as follows: On September 16, 2026, at the closing under the Share Purchase and Option Agreement dated August 5, 2026 between the Issuer and the LLC, as amended by Amendment No. 1 dated September 16, 2026 (as amended, the "SPA"), the LLC sold to the Issuer 486,860 shares of M.E.A. Testing Systems Ltd., an Israeli private company ("MEA"), representing 15% of MEA's share capital on a fully diluted basis. As consideration, the LLC became entitled at the closing to receive 130,000 shares of Common Stock for the initial 10% interest (the 1,300,000 shares provided for in the original agreement, as adjusted for the reverse stock split), and 65,000 additional shares of Common Stock for the additional 5% interest, subject to authorization by the NYSE American of the listing of the additional shares.

No cash was paid by the LLC for the shares. In connection with the SPA, the Issuer also made available to the LLC a loan facility of up to $475,000, bearing interest at 12% per annum and convertible at the Issuer's election into shares of MEA only.
