Taiwan Semiconductor Manufacturing Company Limited stock (ISIN US8740391003) closed at USD 417.72 on the New York Stock Exchange on September 16, 2026, up 0.96% from the prior close as investors continued to digest strong Q2 2026 results and an increasingly optimistic full-year outlook. As 24/7 Wall St reported on September 16, 2026, the company raised its full-year 2026 growth guidance to slightly above 40 percent in US dollar terms after a strong second quarter.
Q2 2026 results show strong growth and margin expansion
According to 24/7 Wall St on September 16, 2026, Taiwan Semiconductor Manufacturing generated USD 40.2 billion in revenue in Q2 2026, an increase of 36.0 percent year over year, underscoring the strength of demand for advanced chips. In the same quarter, the company posted earnings per share of USD 4.31, which exceeded the consensus estimate of USD 3.8866 by 10.89 percent, demonstrating TSMC's ability to translate top-line growth into bottom-line outperformance.
The strong revenue and earnings were accompanied by notable margin expansion. As 24/7 Wall St detailed, TSMC reported a gross margin of 67.7% in Q2 2026, up 9.1 percentage points compared with the prior-year quarter, reflecting higher utilization and pricing power at leading-edge nodes. Advanced nodes at 7 nanometers and below contributed 77% of wafer revenue, with 3-nanometer technology accounting for 30%, 5-nanometer for 33% and an initial 2-nanometer offering contributing 3% in its first commercial quarter, a mix that supports premium pricing and higher profitability.
Guidance, monthly revenue and earnings expectations into October
Beyond the quarterly snapshot, management signaled confidence in the trajectory of the business. According to 24/7 Wall St, August 2026 monthly revenue rose 53.3 percent year over year, reinforcing the momentum seen in the second quarter and supporting the decision to raise full-year 2026 revenue growth guidance to slightly above 40 percent in US dollar terms. For investors, that combination of double-digit revenue growth and accelerating margins is a central part of the investment case.
Looking ahead, the next major checkpoint will be the upcoming quarterly report. As AltIndex noted on September 17, 2026, TSMC is scheduled to report its next earnings on October 14, 2026, with analyst consensus expecting earnings per share of USD 3.80 for the quarter. AltIndex's AI score for the stock currently stands at 86, which the service characterizes as leaning bullish into the print, with 5 out of 6 tracked alternative data signals trending positively over the past three months.
