Semiconductor manufacturing, our customers’ business, involves the complete fabrication of multiple dies or integrated circuits on a wafer. This involves the repetition of a set of core processes and can require hundreds of individual steps. Fabricating these devices requires highly sophisticated process technologies to integrate an increasing array of new materials with precise control at the atomic scale. Along with meeting technical requirements, wafer processing equipment must deliver high productivity and be cost-effective.</span></div><div style="margin-top:10pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">The Company sells its products and services primarily to companies involved in the production of semiconductors in the United States, China, Europe, Japan, Korea, Southeast Asia, and Taiwan.</span></div><div style="margin-top:10pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">The semiconductor industry is cyclical in nature and has historically experienced periodic downturns and upturns. Today’s leading indicators of changes in customer investment patterns, such as electronics demand, memory pricing, and foundry utilization rates, may not be any more reliable than in prior years. Demand for the Company’s equipment can vary significantly from period to period as a result of various factors including, but not limited to economic conditions; supply, demand, and prices for semiconductors; customer capacity requirements; and the Company’s ability to develop and market competitive products. For these and other reasons, the Company’s results of operations for fiscal years 2022, 2021, and 2020 may not necessarily be indicative of future operating results.</span></div><div style="margin-top:10pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">Reclassification: Certain amounts for the fiscal year 2021 footnotes have been reclassified to conform to the fiscal year 2022 presentation.</span></div>
