Research and Development
Research and development expenses decreased to $2,796,171 for the nine-month period ended June 30, 2023 from $3,013,162 for the nine-month period ended June 30, 2022, a decrease of $216,991 or 7%. This decrease is primarily due to decreased outsourced service contracts and laboratory supplies of approximately $180,000. These costs were to support our continued research and development efforts, primarily related to our ongoing animal vaccine study, as well as next generation sequencing projects. Additional decreases of $46,000 occurred related to development projects in the cannabis market during the prior fiscal year period.

Liquidity and Capital Resources

For the nine-month period ended June 30, 2023, we used cash in operating activities of $3,537,911 consisting primarily of our loss of $6,407,265 net with non-cash adjustments of $1,032,568 in depreciation and amortization charges, $334,700 in unrealized loss on change in fair value of warrants classified as a liability, $692,394 in stock-based compensation expense, $62,000 for the write-off of property and equipment and $255,853 of bad debt recovery. Additionally, we had a gain on the sale of property and equipment of $6,083, a net decrease in operating assets of $3,598,665 and a net decrease in operating liabilities of $1,919,637.

Historically, a majority of our revenue attributable to our MDx Testing Services has been derived from our safeCircle COVID-19 testing solutions. On April 11, 2023, the U.S. National Emergency in response to the COVID-19 pandemic was terminated. While we continue to support several safeCircle customers, we are currently observing a marked decrease in demand for COVID-19 testing, which we believe will continue to result in significantly lower revenues from our safeCircle COVID-19 testing solutions in subsequent quarters. On May 1, 2023, we received notice from CUNY, our largest safeCircle COVID-19 testing solution customer, that CUNY is terminating their COVID-19 testing contract with ADCL effective no later than June 30, 2023. Testing under this contract ceased during June 2023. The CUNY COVID-19 testing contract represented 58% of our revenue for fiscal year 2022. These factors could also have a negative impact on the Company’s future liquidity.
We have recurring net losses, which have resulted in a net loss of $6,407,265 and generated negative operating cash flow of $3,537,911 for the nine-month period ended June 30, 2023. These factors raise substantial doubt about our ability to continue as a going concern for one year from the issuance of the financial statements. The ability of the Company to continue as a going concern is dependent on the Company’s ability to further implement its business plan, raise capital, and generate revenues. The financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.
