Our results of operations may continue to reflect the adverse impact from the COVID-19 pandemic, including its impact on our supply chain and inflationary pressures.
Reductions in defense, space or homeland security spending by U.S. and/or foreign customers could reduce our revenues.
We are subject to the risks associated with sales to foreign customers, which could harm our business.
