RTX vs ASML Comparison

RTX is an aerospace and defense manufacturer formed from the merger of United Technologies and Raytheon, with roughly equal exposure across three segments, mostly as a supplier to commercial aerospace and to the defense market: Collins Aerospace, a diversified aerospace supplier; Pratt & Whitney, a commercial and military aircraft engine manufacturer; and Raytheon, a defense prime contractor providing a mix of missiles, missile defense systems, sensors, hardware, and communications technology to the military.

ASML is the leader in lithography systems for manufacturing semiconductors with 90% market share. Lithography is the process in which a light source is used to expose circuit patterns from a photo mask onto a semiconductor wafer. Lithography allows chipmakers to increase the number of transistors on the same area of silicon, with lithography historically representing a high portion of the cost of making cutting-edge chips. ASML outsources the manufacturing of most of its parts, acting like an assembler. ASML's largest clients are TSMC, Samsung, Intel, SK Hynix, and Micron.
