The Company continues to evaluate and invest in programs designed to support its employees, communities, and long-term business objectives. Manufacturing Processes Our success in developing and manufacturing many of our products depends on our ability to tailor the optical and physical properties of technically challenging materials, components, and photonics-based solutions across our target markets. The ability to produce these complex materials, and to control their quality and in-process yields, is an expertise of the Company that is critical to our customers. In the markets we serve, there is a limited number of high-quality suppliers of many of the components we manufacture. Aside from datacenter transceivers, there are very few industry-standard products. Our lasers are displacing conventional technologies because they can do the job faster, yield higher quality, provide overall economic benefits, and enable next-generation applications. Overall, our key differentiators are our deep technology expertise and our broad portfolio solutions, combined with our ability to deliver volume solutions at scale. We continue to increase our use of renewable energy to power our operations and lower our greenhouse gas footprint. We have on-site solar systems at several facilities that further contribute to our renewable energy efforts. Our team also works to minimize energy usage, water usage, other raw materials usage, and waste generation. Coherent has set as a top priority to reduce its carbon footprint across its global operations. Additional information on the Company’s sustainability performance can be found on the ESG section of our website at www.coherent.com. The website address is intended to be an inactive textual reference only. None of the information on, or accessible through, our website is part of this Annual Report on Form 10-K, nor is it incorporated herein by reference. 8 Table of Contents Sources of Supply In our production processes, we use certain substrates, along with numerous optical, electrical, and mechanical parts that are sourced from third-party suppliers. These include InP substrates, 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 Industrial 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 continuously work to strengthen and diversify our supply chain, including maintaining buffer inventory and developing multiple sources of supply. 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. Reporting Segments and Business Units For fiscal year 2026, the Company reports its results in two reporting segments: (i) Datacenter & Communications, and (ii) Industrial.
