Item 4 — Purpose of Transaction
Item 4 of the Schedule 13D is hereby amended and supplemented as follows: Additional Loan. On June 30, 2026, the Issuer borrowed an additional $1,000,000 from Kaufman Kapital pursuant to a Third Amended and Restated Senior Secured Promissory Note in the principal amount of $4,000,000 (the "Amended Non-Convertible Note"), which amends and restates the Second Amended and Restated Senior Secured Promissory Note issued by the Issuer to Kaufman Kapital dated May 15, 2026. The Issuer disclosed the Additional Loan in a Current Report on Form 8-K filed on July 1, 2026. The Issuer stated in that Current Report that it intends to use the proceeds of the Additional Loan for working capital purposes for the production of customer orders. The Amended Non-Convertible Note matures on January 28, 2027 and bears interest at 8% per annum. The Amended Non-Convertible Note is not convertible into Common Stock and no equity securities, warrants, registration rights or other equity-linked consideration were issued to Kaufman Kapital in connection with the Additional Loan. The Amended Non-Convertible Note does not amend the conversion price, conversion ratio, underlying security, maturity date, beneficial ownership limitation or conversion mechanics of the Convertible Note. Share Sales. Following Amendment No. 5, Kaufman Kapital sold an aggregate of 55,000 shares of Common Stock in open market transactions pursuant to the Issuer's effective resale registration statement. Following such sales, the Reporting Persons' remaining direct common stock holdings consist of 445,000 shares acquired upon exercise of the $1.50 Warrant on May 7, 2026. Current Plans and Purposes. The Reporting Persons currently hold the securities of the Issuer for investment purposes. The Reporting Persons continuously evaluate their investment in the Issuer based on a variety of factors, including the Issuer's financial condition, results of operations, business prospects, general market and economic conditions, and other factors. Depending on such evaluation, the Reporting Persons may from time to time acquire additional securities of the Issuer, including through conversion of outstanding Convertible Note principal and accrued interest, subject to the Beneficial Ownership Limitation described below, dispose of some or all of the securities of the Issuer, including through open-market sales, privately negotiated transactions, block trades, registered offerings or otherwise, or take any other action with respect to their investment in the Issuer as they may deem appropriate. Any such transactions may be effected at any time and from time to time, subject to applicable law, and will depend upon a variety of factors, including those described above. Sales of directly held Common Stock may increase the number of shares issuable upon conversion of the Convertible Note that may be acquired without exceeding the Beneficial Ownership Limitation, without increasing the Reporting Persons' aggregate beneficial ownership above the Maximum Percentage. Except as otherwise described in this Amendment, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the matters described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.
