Notes to Financial Statements
Subsequent Events [Text Block]	16. Subsequent Events The Company evaluates and discloses subsequent events as required by ASC Topic No. 855, Subsequent Events. The Topic establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before the financial statements are issued or are available to be issued. On February 3, 2026, the Company entered into a Note Purchase Agreement (the “Note Agreement”) with the Smith Living Trust, for which William W. Smith, Jr., the Company’s Chairman, President and Chief Executive Officer, and his wife, Dieva L. Smith, serve as co-trustees (“Smith”). Pursuant to the Note Agreement, Smith agreed to loan funds to the Company in return for one or more secured promissory notes (in each case, a “Note”) and accompanying unregistered common stock purchase warrants (in each case, a “Warrant”). The Note Agreement provides that each Note will be secured by the Company’s accounts receivable and certain other assets, will bear interest at a rate of 15.0% per annum, and will be due on or before March 31, 2026 (the “Maturity Date”), unless otherwise mutually agreed by the parties. Pursuant to the Note Agreement, each Note will be accompanied by the issuance of a Warrant to purchase shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), which will be exercisable at any time beginning six months following its original issuance, will expire five years from the initial exercise date and will have an exercise price equal to the greater of (a) $0.68 and (b) the greater of the market price of the Company’s Common Stock on the date of the Note Agreement or on the date of issuance. On February 3, 2026, the Company and Smith completed a closing of a loan transaction under the Note Agreement, and the Company issued a Note and a Warrant to Smith pursuant to the terms of the Note Agreement. The Warrant has an exercise price of $0.68 and will be exercisable during the period beginning August 3, 2026 and ending August 3, 2031. The gross proceeds to the Company from the closing totals approximately $1,000,000 (comprised of approximately $814,979 as a loan and approximately $185,021 for the purchase of the accompanying Warrant), before deducting transaction expenses payable by the Company. The Company expects to use the net proceeds from the transaction for working capital and general corporate purposes. The transaction was approved by the Company’s Board of Directors and the Company’s Audit Committee. On March 4, 2026, the Company entered into a Securities Purchase Agreement for the sale of Secured Convertible Notes (the “2026 Convertible Notes”) with an aggregate original principal amount of $4.9 million and an initial conversion price of $0.68 per share, subject to adjustment, and warrants to acquire up to an aggregate amount of approximately 9.4 million additional shares of the Company's common stock. The Smith Living Trust, for which William W. Smith, Jr., the Company’s Chairman, President and Chief Executive Officer, and his wife, Dieva L. Smith serve as co-trustees, and Timothy C. Huffmyer, the Company’s Chief Operating Officer, Chief Financial Officer and Treasurer, are among the buyers in the offering. The Company has agreed to use the proceeds of the offering (i) to repay in full the principal and interest outstanding under those certain notes due on March 31, 2026 in the aggregate amount of up to $2.2 million plus any additional interest amounts that may accrue in connection with the extension of the maturity date under the existing notes and (ii) for general corporate purposes. The 2026 Convertible Notes will mature on March 31, 2029; however, this date may be extended at the option of the holder. The 2026 Convertible Notes will accrue interest at the rate of 8.0% per annum, which will be payable in full upon the Maturity Date. Upon the occurrence and during the continuance of an Event of Default (as defined in the 2026 Convertible Notes), the 2026 Convertible Notes will accrue interest at the rate of 12.0% per annum. At any time after the sixth month anniversary of the issuance of the 2026 Convertible Notes, each 2026 Convertible Note will be convertible, at the option of the holder, into shares of our common stock at an initial conversion price equal to $0.68, which is subject to standard adjustments. The offering was approved by the Company’s Board of Directors and the Company’s Audit Committee and is expected to close on or about March 6, 2026, subject to customary closing conditions. The aggregate gross proceeds from the offering are expected to be approximately $4.9 million, before deducting offering expenses payable by the Company. On March 3, 2026, the Company's Board of Directors approved the appointments of William W. Smith Jr. as Executive Chairman of the Board of Directors, Timothy C. Huffmyer as President and Chief Executive Officer, and Bethany M. Braund as Chief Financial Officer and Treasurer, each effective as of the close of business on March 31, 2026. F-32
