We rely to a substantial extent on third parties to supply certain raw materials that are critical to the manufacture of our products. Purchase prices and availability of these critical items are subject to volatility, and in some cases, we have supply arrangements with only a limited number of suppliers for a given material. At any given time, we may be unable to obtain an adequate supply of these critical raw materials on a timely basis, on price and other terms acceptable to us, or at all. If suppliers increase the price of critical raw materials, we may not have alternative sources of supply. In addition, to the extent that we have quoted prices to customers and accepted customer orders for products prior to purchasing necessary raw materials, or have existing contracts, we may be unable to raise the price of products to cover all or part of the increased cost of the raw materials. We source some of these materials from China, which has and may in the future continue to impose export controls that could limit or significantly delay our access to such materials and could compel us to identify alternative sources, which we may not be able to do in a timely fashion or at all. The prices for many of the raw materials we use have been volatile during the past several years. Due to the long lead times required to manufacture many of our products, volatility in raw material prices exposes us to cash costs that may not be fully recovered through surcharge and index pricing mechanisms. Recently, due to inflationary trends, certain critical raw material costs, such as nickel, hafnium, titanium sponge, cobalt, chromium, and molybdenum and scrap containing iron, nickel, titanium, chromium, and molybdenum have been volatile and they may continue to be so in the future, including as a result of changes in international trade policy. While we have been able to mitigate some of the adverse impact of volatile raw material costs through various means, including the application of raw material surcharges or pricing indices to customers, rapid changes in raw material costs cause volatility in, and may adversely affect, our results of operations.
The manufacture of some of our products is a complex process and requires long lead times. As a result, we may experience delays or shortages in the supply of raw materials. In particular, we acquire certain important raw materials that we use to produce specialty materials, including nickel, zirconium, niobium, chromium, cobalt, vanadium and titanium sponge, from foreign sources. Some of these sources operate in countries that may be subject to unstable political and economic conditions. These or similar conditions may disrupt supplies or affect the prices of the materials that are necessary to our operations. If unable to obtain adequate and timely deliveries of required raw materials, we may be unable to timely manufacture sufficient quantities of products. This could cause us to lose sales, incur additional costs, delay new product introductions, or suffer harm to our reputation.
