IMPACT OF COVID-19	NOTE 2 — IMPACT OF COVID-19 The COVID-19 pandemic has disrupted business, trade, commerce, financial and credit markets, in the U.S. and globally. Orion’s business was adversely impacted by measures taken by customers, suppliers, government entities and others to control the spread of the virus beginning in March 2020, the last few weeks of Orion’s 2020 fiscal year, and continuing most significantly into the second quarter of fiscal 2021. During the third quarter of fiscal 2021, Orion experienced a rebound in business as project installations resumed for its largest customer. However, potential future risks remain due to the COVID-19 pandemic. It is not possible to predict the overall impact the COVID-19 pandemic will have on Orion’s business, liquidity, capital resources or financial results, although the economic and regulatory impacts of COVID-19 significantly reduced Orion’s revenue and profitability in the first half of fiscal 2021. If the COVID-19 pandemic becomes more pronounced in Orion’s markets or experiences a resurgence in markets recovering from the spread of COVID-19, Orion’s results of operation would likely be materially adversely affected.
