The Company is further unable to accurately predict the full impact that the COVID-19 pandemic will have on its results of operations or financial condition due to numerous factors that are not within its control, including the duration and severity of the outbreak together with any potential statewide closures if cases increase, the spread of COVID-19 variants, including the Delta variant, and the widespread adoption of vaccination measures including recently approved booster regimens.
