[2] | COVID-19 PandemicThe COVID-19 pandemic began to impact our business late in fiscal 2020. The pandemic and related public health recommendations and mandated precautions to mitigate the spread of COVID-19, including deferral of surgical procedures and treatments and shelter-in-place orders or similar measures, negatively affected some of our operations, which impacted our operating results, financial position and cash flows. We have experienced and expect to continue to experience unpredictable fluctuations in demand for certain of our products and services. Also, the COVID-19 pandemic has caused and continues to cause disruptions in our supply chain and labor scarcity resulting in material and labor cost inflation. External factors such as policymaker decisions to remove certain restrictions, as they evaluate the continued infection rate and COVID-19 related deaths, the emergence of new variants of the virus, and the distribution of available vaccines create uncertainty regarding future demand from our Customers and the ability of our suppliers to meet our demands. However, order momentum has continued to improve and increased demand for certain capital equipment products strengthened from the fourth quarter of fiscal 2021.
