Segment Reporting | In the third quarter of 2023, in order to align its segment financial reporting with a change in its business structure, the Company realigned its segments. Following the segment realignment, the Company’s three reportable segments are as follows: (1) Materials Solutions, (2) Microcontamination Control, and (3) Advanced Materials Handling. The current interim and succeeding annual periods will disclose the reportable segments with prior periods recast to reflect the change. The Company’s financial segment reporting reflects an organizational alignment intended to leverage the Company’s unique breadth of capabilities to create mission-critical advanced materials, microcontamination control products, and advanced materials handling solutions that maximize manufacturing yields, reduce manufacturing costs and enable higher device performance for its customers. While these segments have separate products and technical know-how, they share common business systems and processes, technology centers, and strategic and technology roadmaps. The Company leverages its expertise from these three segments to create new and increasingly integrated solutions for its customers. The Company reports its financial performance in the following segments: • Materials Solutions: MS provides advanced consumable materials, such as chemical mechanical planarization (“CMP”) slurries and pads, deposition materials, process chemistries and gases, formulated cleans, etchants and other specialty materials, that enable our customers’ technical roadmap, improve device performance, lower their total cost of ownership and enhance their yields. • Microcontamination Control: MC offers solutions to filter and purify critical liquid and gaseous chemistries used in semiconductor manufacturing processes and other high-technology industries. • Advanced Materials Handling: AMH develops solutions to monitor, protect, transport and deliver critical liquid chemistries, wafers and other substrates for a broad set of applications in the semiconductor industry, life sciences and other high-technology industries. Summarized financial information for the Company’s reportable segments is shown in the following tables.
