Our measure of profit/loss for segment reporting purposes is Adjusted Operating EBITDA as this is the manner in which our CODM assesses performance and allocates resources. We define Adjusted Operating EBITDA as earnings (i.e., “Income (loss) before income taxes") before interest, depreciation, amortization, non-operating pension / other post-employment benefits (“OPEB”) / charges, and foreign exchange gains / losses, indirect legacy costs, and adjusted for significant items.

SEMICONDUCTOR TECHNOLOGIES

Semiconductor Technologies net sales were $744 million for the three months ended June 30, 2026, up 16% as compared to $644 million for the three months ended June 30, 2025. Net sales increased due to an 18% increase in volume. The increase in sales volume was due to ongoing end-market demand strength related to improved customer utilization rates and growth in AI driven applications, particularly in advanced nodes, including advanced packaging and high bandwidth memory. These increases were partially offset by unfavorable local price and product mix and currency impacts.

Adjusted Operating EBITDA was $253 million for the three months ended June 30, 2026, up 12% as compared to $226 million for the three months ended June 30, 2025, primarily due to volume growth partially offset by investments to support future growth, including R&D and supply chain initiatives.
