About

Atonarp is a deep-tech sensing company with headquarters in Osaka, Japan and operations in San Jose, California that develops mass spectrometry-based molecular sensing instruments designed for in-situ, real-time analysis of process gases and chemical environments inside semiconductor fabrication equipment. The company was founded with the premise that semiconductor manufacturing process control is constrained by the inability to measure the actual chemical composition of processes as they occur inside the reactor chamber — current process control relies primarily on indirect sensors like pressure, temperature, and power measurements that correlate with process conditions but do not directly measure the chemical species being deposited or etched. Atonarp's molecular sensing technology provides direct, real-time chemical composition data from inside the process environment, enabling a new class of process control that responds to actual chemical state rather than inferred process conditions.

About

Nucor Corporation is a Charlotte, North Carolina-based steel and steel products manufacturer — publicly traded on the New York Stock Exchange (NYSE: NUE) as an S&P 500 Materials component — operating as the largest steel producer in the United States and the most profitable steelmaker in North America, using electric arc furnace (EAF) technology to produce flat-rolled steel, long steel products, structural steel, and steel products at approximately 25 steel mills and 40+ downstream fabrication facilities, through approximately 32,000 employees. Nucor's EAF-based steelmaking model (melting recycled steel scrap rather than processing iron ore in a blast furnace) produces a lower-carbon-intensity ton of steel at lower operating cost and with significantly more production flexibility than integrated blast furnace producers — making Nucor the cost benchmark against which competing steel technologies are measured. In 2024, Nucor navigated a steel price correction after the 2021-2022 post-pandemic construction and infrastructure demand surge — revenue declined from approximately $36-37 billion at the 2022 peak to approximately $30 billion in 2024 as flat-rolled steel prices normalized. Nucor has invested more than $10 billion in capacity expansion since 2018 — including new sheet mills in Gallatin, Kentucky; Lexington, North Carolina; Nucor Steel West Virginia; and Nucor Steel Brandenburg — dramatically increasing its flat-rolled sheet production capacity to serve automotive, construction, and advanced manufacturing customers. CEO Leon Topalian has led Nucor's strategy of organic capacity expansion, new product development, and shareholder-friendly capital allocation (dividends paid for 200+ consecutive quarters).
