Business Description

Our Company Qnity is one of the largest global leaders in materials and solutions for the semiconductor and electronics industries. We empower our customers’ technology roadmaps to enable advancements in megatrends such as artificial intelligence, high-performance computing and advanced connectivity. We partner with leading semiconductor and advanced device manufacturers to address complex challenges and develop solutions that facilitate next-generation technological innovations. With over 50 years of experience in systems engineering and material science, a global manufacturing footprint and major application labs across the world, we are well-positioned to capitalize on emerging opportunities across various sectors including data centers, communications infrastructure, industrials, automotive, and consumer electronics. On May 22, 2024, DuPont de Nemours, Inc. ("DuPont" or "Parent") announced its plan to separate Qnity from DuPont into an independent publicly traded company (the “Separation”). On November 1, 2025 (the "Separation and Distribution Date"), DuPont completed the Separation through a pro-rata distribution of one share of Qnity common stock for every two shares of DuPont common stock held at the close of business on the record date of October 22, 2025 (the "Distribution"). As a result of the Distribution, as of the Separation and Distribution Date, Qnity became an independent, publicly traded company, and Qnity common stock commenced trading on the New York Stock Exchange under the symbol "Q" at the start of trading on November 3, 2025. We have aligned our businesses, and report our financial results, across two operating segments: • Semiconductor Technologies: Our Semiconductor Technologies segment provides a portfolio of innovative materials and solutions utilized across multiple stages of the semiconductor manufacturing process. These advanced materials are qualified into customers’ roadmaps, designed to improve chip performance, enhance yield and enable leading-edge node technology. • Interconnect Solutions: Our Interconnect Solutions segment offers what we believe to be a comprehensive range of best-in-class material solutions that address the evolving complexities of signal integrity, thermal and power management and advanced packaging. These solutions are integral for advanced electronics hardware, including complex printed circuit boards and advanced semiconductor packaging. Our broad portfolio of solutions and materials across both Semiconductor Technologies and Interconnect Solutions segments positions us as a comprehensive solutions provider for our customers. We collaborate with key players throughout the electronics value chain, including many of the leading semiconductor device manufacturers, foundries and equipment providers. Additionally, we partner with original equipment manufacturers ("OEMs") who specify our products into their manufacturing process. Qnity is often the partner of choice due to our strong innovation capabilities and extensive materials and engineering expertise. In a fast-paced electronics industry, our customers’ needs are highly performance-driven and our long-standing relationships and strong renewal rates demonstrate our commitment to delivering excellence in a demanding market. Our products are consumable or unit-driven, with over 90% of Qnity’s revenue in 2025 generated from products that are either utilized in the manufacturing process or incorporated into final electronic devices. 6 Table of Contents Semiconductor Technologies Segment Semiconductor Technologies lines of business and applications are as follows: Line of Business Applications Advanced Cleans and CMP Slurries We are a leading provider of CMP slurries and specialty cleaning chemistries for liquid and dry film photoresist removal, post-CMP cleaning, selective etching and post-etch residue cleaning.
