Trends and Uncertainties
The following is a discussion of certain trends and uncertainties that we believe have influenced, and may continue to influence, our results of operations.
Coronavirus Pandemic. The coronavirus disease 2019 (“COVID-19”) pandemic has dramatically impacted the global health and economic environment, with millions of confirmed cases, business slowdowns and shutdowns, and market volatility. The COVID-19 pandemic has caused, and may continue to cause, significant economic disruptions and has impacted, and may continue to impact, our operations and the operations of our suppliers, logistics providers and customers as a result of supply chain disruptions and delays, as well as labor challenges. During the early stages of the pandemic, our Healthcare division experienced increased demand for certain products as a result of COVID-19. However in our Security division, throughout and primarily as a result of the pandemic, receipt of certain orders was delayed, most notably with respect to our aviation and cargo products, and our revenues were adversely impacted. If customers of our Security division continue to be impacted by the pandemic, we could receive further requests to delay deliveries of equipment and modify service arrangements or the scheduling of factory or site acceptance tests, which could further impact timing of revenue recognition. While we have been able to broadly maintain our operations, we experienced some disruption in our supply chain in certain markets due primarily to materials shortages, longer lead times on deliveries and transportation constraints. If these business interruptions resulting from COVID-19 were to be prolonged or expanded in scope, our business, financial condition, results of operations and cash flows would be materially and adversely impacted. We intend to continue to actively monitor the situation and may take further actions that alter our business operations as may be required by federal, state or local authorities or that we determine are in our best interests and the best interests of our employees, suppliers and customers. The ultimate impact of COVID-19 on our operations and financial performance in future periods remains uncertain and will depend on future pandemic-related developments, including the duration of the pandemic, potential subsequent waves of COVID-19 infection or potential new variants, the effectiveness and adoption of COVID-19 vaccines and therapeutics, impacts on suppliers and related government actions to prevent and manage disease spread such as the implementation of any federal, state, local or foreign vaccine mandates. The long-term impacts of COVID-19 on government budgets and other funding priorities, including international priorities, that impact demand for our products and services are also difficult to predict, but could negatively affect our future results and performance.
Global Economic Considerations. Our products and services are sold in numerous countries worldwide, with a large percentage of our sales generated outside the United States. Therefore, we are exposed to and impacted by global macroeconomic factors, U.S. and foreign government policies and foreign exchange fluctuations. There is uncertainty surrounding macroeconomic factors in the U.S. and globally characterized by the supply chain environment, inflationary pressure, rising interest rates, and labor shortages. In addition to the COVID-19 pandemic, these other global macroeconomic factors, coupled with the U.S. political climate and political unrest internationally, have created uncertainty and impacted demand for certain of our products and services. Also, the continued conflict between Russia and Ukraine and the sanctions imposed in response to this conflict have increased global economic and political uncertainty. While the impact of these factors remains uncertain, we will continue to evaluate the extent to which these factors will impact our business,
