COVID-19

The travel and other restrictions that began in March 2020 in response to the COVID-19 global pandemic resulted in a significant slowdown in our field studies and sales efforts. We were able to resume some projects by mid-year 2020, however, we still have delays on certain projects that might remain on hold until businesses and government entities return to more normal operations. These continued delays have impacted our results of operations and could impact our results in future quarters. In addition, extended stay at home orders and other social distancing initiatives severely limited our ability to communicate with current and potential commercial and governmental customers. While many restrictions were lifted during our second and third fiscal quarters of 2021, we have not returned to full scope pre-pandemic activities, and are uncertain as to when or if, with potential further restrictions, that may occur. The COVID-19 pandemic is also placing a significant budgetary burden on federal, state and local governments, which may impede or delay their ability to purchase our products.

The Company has evaluated subsequent events from the balance sheet date through November 12, 2021, the date at which the financial statements were issued, and determined that there were no other items that require adjustment to or disclosure in the financial statements.
