Taiwan Semiconductor Manufacturing Company stock (ISIN US8740391003) closed at USD 430.26 on the New York Stock Exchange on September 17, 2026, up 3.0 percent from the previous close as investors focused on new 2-nanometer chip orders and ambitious expansion plans in advanced nodes.

MediaTek order and Longtan expansion support growth story

Fresh attention for Taiwan Semiconductor Manufacturing Company came after MediaTek selected the foundry's 2-nanometer process for its new Dimensity 9600 Pro platform, while keeping the broader 9600M line on 3-nanometer technology, according to Yahoo Finance on September 18, 2026.

In parallel, Taiwan Semiconductor Manufacturing Company announced plans to expand its operations in Longtan for processes at 1.4 nanometers and below, underscoring its push deeper into leading-edge manufacturing, as reported by GuruFocus on September 18, 2026.

Over the past year the stock has delivered a 61.47 percent total shareholder return, while year-to-date performance stands at 34.62 percent, illustrating how the long-term momentum remains strong even though the share price slipped 6.89 percent over the last 90 days to the current USD 430.26 level, according to Yahoo Finance.

Record Q2 2026 figures and guidance upgrade

The latest available quarterly figures show that in Q2 2026 Taiwan Semiconductor Manufacturing Company generated revenue of USD 40.20 billion, highlighting the scale of its operations, as summarized by MSN on September 17, 2026.

In that same quarter, gross margin reached 67.7 percent, while high-performance computing accounted for 66 percent of revenue, underlining how advanced compute workloads now dominate the business mix, according to MSN.

Two-nanometer chips already contributed 3 percent of wafer revenue in their commercial debut during Q2 2026, a figure that gives investors a concrete sense of how quickly customers are moving to next-generation nodes, based on the same MSN report.

Management has raised its full-year growth guidance to slightly above 40 percent for 2026, upgrading expectations compared with earlier outlooks and reinforcing the perception of strong demand for advanced manufacturing capacity, according to MSN.

Revenue acceleration and valuation signals

More recent monthly data underline the acceleration in the top line: August 2026 revenue reached a record 514.8 billion New Taiwan dollars, roughly USD 16.1 billion, which represents a 53.3 percent increase versus the same month a year earlier and a 10.1 percent rise compared with July 2026, according to TipRanks on September 17, 2026.

With the stock trading around USD 425 to USD 430, Taiwan Semiconductor Manufacturing Company is valued at about 25 times the 2026 consensus earnings per share estimate of USD 16.93, based on TipRanks.

On a different valuation lens, GuruFocus estimates a GF Value of USD 363.99 for Taiwan Semiconductor Manufacturing Company, meaning that at a current price of USD 430.26 the shares trade about 18.2 percent above that intrinsic value estimate and are therefore flagged as overvalued in that framework, as reported by GuruFocus on September 17, 2026.

Despite that overvaluation signal, TSMC holds a GF Score of 98 out of 100 and a financial strength rank of 9 out of 10, figures that emphasize the company’s robust balance sheet and operating metrics even as investors debate how much of that strength is already reflected in the share price, according to the same GuruFocus article.
