Sources of Supply

In our production processes, we use numerous optical, electrical, and mechanical parts that are sourced from third-party suppliers. These include ICs, DSPs, mechanical housings, and optical components, and we commonly refer to them as raw materials. Raw materials or subcomponents required in the manufacturing process are generally available from several sources. However, in the Lasers segment, we currently purchase several key components and materials used in the manufacture of our products, including exotic materials, crystals, and optics, from sole-source or limited-source suppliers. We also purchase assemblies and turnkey solutions from contract manufacturers, based on our proprietary designs. We rely on our own production and design capability to manufacture and specify certain strategic components, crystals, fibers, semiconductor lasers, and laser-based systems. We use rare-earth materials in some of our production processes. Like with other materials, we are constantly working to strengthen and diversify our supply chain for resilience. These strategies include maintaining additional buffer stocks and securing multiple sources to ensure resilience.

The continued high quality of and access to these raw materials are critical to the stability and predictability of our manufacturing yields. We specify and test these raw materials at the onset of and throughout the production process. Additional research and capital investment are sometimes needed to better define future raw materials specifications. We continue to develop strategic second sources as part of our overall business continuity planning, and occasionally experience problems associated with raw materials not meeting contract specifications for quality or purity. Risks associated with reliance on third parties for the timely and reliable delivery of raw materials are discussed in greater detail in Item 1A. Risk Factors of this Annual Report on Form 10-K.
