Qnity plays a critical role in the semiconductor value chain and is uniquely positioned to collaborate with leading global technology players to solve challenges across the industry. As an integrated end-to-end solutions provider, Qnity delivers products from chip fabrication and advanced packaging to high-end printed circuit boards, assembly and display solutions.

“This week we successfully launched Qnity as an independent, pure-play company focused on making tomorrow’s technologies possible,” said Jon Kemp, Qnity’s Chief Executive Officer. “We have delivered six consecutive quarters of strong organic growth, reflecting the breadth of our portfolio and the power of our innovation partnerships with customers. Our performance reflects our position as a Partner of Choice with a broad range of offerings, deep application engineering expertise, and robust system integration capabilities.”

Overview of Third Quarter 2025 Results

Net sales¹ of $1.3 billion increased 11% from the prior year period. Growth was driven by increased AI demand across advanced nodes, advanced packaging, and thermal management solutions.

Estimated GAAP Net Income² of approximately $220 million and Pro Forma and Management Adjusted Net Income³ of $155 million increased 6% and 16%, respectively, from the prior year period. Higher volumes were partially offset by unfavorable mix and currency as well as selective growth investments.

Estimated Adjusted Pro Forma Operating EBITDA⁴ was up approximately 6% from the prior year period with margin⁵ of approximately​ 29%. Higher volumes were partially offset by unfavorable mix and currency as well as selective growth investments.

“We have a clear strategic path, operating model and capital allocation plan to deliver above-market growth and strong profitability,” commented Matt Harbaugh, Qnity’s Chief Financial Officer. “Our strong third quarter estimated results are a testament to the team’s continued focus on execution, driving consistent performance throughout the spin process.”
