Financial report summary

  • Risks Related to Our Business
  • Our operating results have varied and will likely continue to vary significantly from quarter to quarter in the future, causing volatility in our stock price.
  • Our largest customers account for a substantial portion of our revenue, and our revenue and cash flows could decline considerably if one or more of these customers were to purchase significantly fewer of our systems or delay or cancel a large order.
  • Our customers may be unable to pay us for our products and services.
  • Variations in the amount of time it takes for us to sell our systems may cause fluctuations in our operating results, which could cause our stock price to decline.
  • Most of our revenue has been derived from customers outside of the United States, subjecting us to operational, financial and political risks, such as unexpected changes in regulatory requirements, tariffs, political and economic instability, outbreaks of hostilities, natural disasters, climate change and difficulties in managing foreign sales representatives and foreign branch operations, as well as risks associated with foreign currency fluctuations.
  • If we deliver systems with defects, our credibility will be harmed and the sales and market acceptance of our systems will decrease.
  • If we are not successful in developing new and enhanced products for the semiconductor device manufacturing industry, we will lose sales and market share to our competitors.
  • If new products developed by us do not gain general market acceptance, we will be unable to generate revenue and recover our research and development costs.
  • Even if we are able to develop new products that gain market acceptance, sales of these new products could impair our ability to sell existing products.
  • Our integrated metrology systems are integrated with systems sold independently by Wafer Fabrication Equipment Suppliers, and a decrease in sales by these suppliers, or the development of competing systems by these suppliers, could harm our business.
  • We may fail to adequately protect our intellectual property and, therefore, lose our competitive advantage.
  • Protection of our intellectual property rights, or the efforts of third parties to enforce their own intellectual property rights against us, may result in costly and time-consuming litigation, substantial damages, lost product sales and/or the loss of important intellectual property rights.
  • Our efforts to protect our intellectual property may be less effective in certain foreign countries where intellectual property rights are not as well protected as in the United States.
  • Some of our current and potential competitors have significantly greater resources than we do, and increased competition could impair sales of our products or cause us to reduce our prices.
  • Because of the high cost of switching equipment vendors in our markets, it is sometimes difficult for us to win new customers from our competitors even if our systems are superior to theirs.
  • We must attract and retain experienced senior executives and other key personnel with knowledge of semiconductor device manufacturing and inspection, metrology or lithography equipment and related software to help support our future growth, and competition for such personnel in our industry is high.
  • We obtain some of the components and subassemblies included in our systems from a limited group of suppliers, and the partial or complete loss of one of these suppliers could cause production delays and a substantial loss of revenue.
  • Any prolonged disruption in the operations of our manufacturing facilities could have a material adverse effect on our revenue.
  • We may outsource select manufacturing activities to third-party service providers, which decreases our control over the performance of these functions and may result in lower quality and functionality of our products.
  • If our network security measures are breached and unauthorized access is obtained to a customer’s data, to our data, or to our information technology systems, we may incur significant legal and financial exposure and liabilities.
  • Failure to adjust our orders for parts and subcomponents in an accurate and timely manner in response to changing market conditions or customer acceptance of our products could adversely affect our financial position and results of operations.
  • Our ability to fulfill our backlog may have an effect on our long-term ability to procure contracts and fulfill current contracts.
  • If we do not manage our supply chain effectively, our operating results may be adversely affected.
  • We may choose to acquire new and complementary businesses, products or technologies instead of developing them ourselves, and we may be unable to complete these acquisitions or may not be able to successfully integrate an acquired business in a cost-effective and non-disruptive manner.
  • If we cannot effectively manage growth, our business may suffer.
  • Risks Related to Tax Laws, Financial Markets and the Environment
  • Changes in tax rates or tax liabilities could affect results.
  • Turmoil or fluctuations in the credit markets and the financial services industry may negatively impact our business, results of operations, financial condition or liquidity, and our factoring arrangements may expose us to additional risks.
  • We are subject to various environmental laws and regulations that could impose substantial costs upon us and may harm our business, operating results and financial condition.
  • Risks Related to Our Recently Completed Merger
  • Combining the businesses of Rudolph and Nanometrics may be more difficult, costly or time-consuming than expected and we may fail to realize the anticipated benefits of the Merger, which may adversely affect our business results and negatively affect the value of our common stock.
  • The failure to successfully integrate the businesses and operations of Rudolph and Nanometrics in the expected time frame may adversely affect our future results.
  • We may not be able to retain customers or suppliers, or customers or suppliers may seek to modify contractual obligations with us, which could have an adverse effect on our business and operations. Third parties may terminate or alter existing contracts or relationships with Rudolph or Nanometrics.
  • We may be exposed to increased litigation due to the Merger, which could have an adverse effect on our business and operations.
  • We may be unable to retain former Rudolph and Nanometrics personnel successfully.
  • Risks Related to the Global Economy and Semiconductor Industry
  • Cyclicality in the semiconductor device industry has led to substantial decreases in demand for our systems and may, from time to time, continue to do so.
  • Our future rate of growth is highly dependent on the development and growth of the market for microelectronic device inspection, lithography and metrology equipment.
  • Risks Related to our Stock
  • Provisions of our charter documents and of Delaware law could discourage potential acquisition proposals and/or delay, deter or prevent a change in control of our company.
  • Our stock price is volatile.
  • There are various risks related to the legal and regulatory environments in which we perform our operations and conduct our business that may expose us to risk.
