As of March 4, 2025, the Company had cash of $2,800,000. The Company believes that such cash, plus the cash expected to be generated from operations, will provide sufficient liquidity to finance the corporate activities of Acorn and operating activities of OmniMetrix at their current level of operations for at least the twelve-month period from the issuance of these audited consolidated financial statements. The Company may, at some point, elect to obtain a new line of credit or other source of financing to fund additional investments in the business. If the Company decides to pursue additional financing in the future, it may be in the form of a bank line, a new loan or investment by others, an equity raise by Acorn which could then facilitate a loan by Acorn to OmniMetrix, or any combination thereof. Whether alternative funds, such as third-party loans or investments, will be available at the time and on terms acceptable to Acorn and OmniMetrix cannot be determined at this time.
