RTX vs TSM 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.

Taiwan Semiconductor Manufacturing Co. is the world's largest dedicated chip foundry, with about 70% market share in 2025. TSMC was founded in 1987 as a joint venture of Philips, the government of Taiwan, and private investors. It went public in Taiwan in 1994 and as an ADR in the US in 1997. TSMC's scale and high-quality technology allow the firm to generate solid operating margins, even in the highly competitive foundry business. Furthermore, the shift to the fabless business model has created tailwinds for TSMC. The foundry leader has an illustrious base of customers, including Apple, AMD, and Nvidia, that look to apply its cutting-edge process technologies to their semiconductor designs. TSMC employs more than 83,000 people.
