SUL is a high turnover low margain business. They carry a lot of stock, but also have a large accounts payable. A portion of their goods are imported from overseas suppliers, not sure what portion of this would be denominated in USD with currency risk. They also have modest long term debts but they have kept under control as they have grown over the last few years. These liablities combined are up around $800~900M.
With an operating margain of ~11%, they wouldn't have to come too far off their revneus of $2.7B before the balance sheet comes under pressure.
If lockdowns and suppressed market continues for more than 6 Months, this business could start to get into trouble depending on access to financing, cost control etc.
