New or increased economic and trade sanctions, including tariffs, may create economic and political uncertainties and could potentially impact the cost of our raw materials and subassemblies having an adverse effect on our business, operations and profitability. Although our supply chain predominantly consists of US based suppliers, and our material costs are established on issued purchase orders, future procurements may be impacted by economic and political uncertainties including tariffs, and may directly affect the Company’s profitability on previously negotiated Firm Fixed Price contracts.
