Global Economic Considerations

The global macroeconomic environment is uncertain, and could be negatively affected by, among other things, increased U.S. disputes with countries that are existing trade partners, instability in the global capital and credit markets, supply chain weaknesses, instability in the geopolitical environment in Asia, Europe and the Middle East, and other tensions. Deterioration in economic factors arising from trade disputes between the United States and China, in particular, could have an adverse impact on the Company's financial results given its customer concentrations in both countries. Such challenges have caused, and may continue to cause, recession fears, fluctuations in interest rates, foreign exchange volatility and inflationary pressures through the imposition of tariffs on sensitive technologies, including semiconductors.

Despite the uncertainty of these challenges, the Company believes it has considered all appropriate factors when making financial estimates and will continue to evaluate the impact of any significant changes resulting from these and other factors affecting the Company’s business performance.
