Liquidity and Capital Resources
Our liquidity needs consist of our working capital requirements and research and development expenditure funding. As of December 31, 2022, we had working capital of $15,002,349. For the three-month period ended December 31, 2022, we used cash in operating activities of $2,383,106 consisting primarily of our loss of $3,844,246 net with non-cash adjustments of $338,918 in depreciation and amortization charges, $2,637,800 in unrealized loss on change in fair value of warrants classified as a liability, $93,748 in stock-based compensation expense and $290,022 of bad debt recovery. Additionally, we had a gain on the sale of property and equipment of $6,083, a net increase in operating assets of $437,308 and a net decrease in operating liabilities of $875,913. Cash provided by investing activities of $45,000 from the sale of property and equipment.
We have recurring net losses. We have incurred a net loss of $3,844,246 for the three-months ended December 31, 2022. Our current capital resources include cash and cash equivalents, accounts receivable and inventories. Historically, we have financed our operations principally from the sale of equity and equity-linked securities. Through December 31, 2022, we have dedicated most of our financial resources to commercialization of our MDx Testing Services, specifically our COVID-19 Testing Services, as well as to research and development efforts focused on the development of our Therapeutic DNA Productions Services, as well as, advancing our intellectual property, and general and administrative activities. We estimate that we will have sufficient cash and cash equivalents to fund operations for the next twelve months from the date of filing of this quarterly report.
We may require additional funds to complete the continued development of our products, services, product manufacturing, and to fund expected additional losses from operations until revenues are sufficient to cover our operating expenses. If revenues are not sufficient to cover our operating expenses, and if we are not successful in obtaining the necessary additional financing, we will most likely be forced to reduce operations.
