TSM Research Update — September 18, 2026 (Updated)
Updated Thesis
Taiwan Semiconductor Manufacturing Company is the world's largest contract chipmaker, manufacturing advanced logic, mixed-signal, RF, and embedded memory wafers for high-performance computing, smartphones, IoT, and automotive customers from a base of 65,152 employees headquartered in Hsinchu, Taiwan. The business quality is exceptionally high: TTM gross margin is 64.2%, TTM operating margin is 56.0%, TTM net margin is 50.4%, and ROE is 39.3%, while revenue grew 36.0% and earnings grew 77.4% in the most recent quarter on a year-over-year basis. Despite that profitability, the shares trade at a P/S of 0.53, a trailing P/E of 1.05, and a P/FCF of 2.1, with EV/EBITDA of 19.23, a combination that screens as cheap on the historical-multiple regime even though the EV/EBITDA multiple is not low in absolute terms.
The investment grade as of this refresh is B — solid business quality. A-tier business, B-tier valuation with 13.9% upside to $515 fair value.
