The article lists TSMC’s London Stock Exchange symbol as OLCV, but the London Stock Exchange’s own market page identifies the instrument code as 0LCV (starting with the numeral zero). This is a ticker-code error, not a naming variant.

TSMC’s official 2021 announcement about creating JASM said Sony would participate only as a minority shareholder; it did not describe JASM as a 70/20 venture, and Denso was not part of that original announcement. In February 2022, TSMC announced that Denso would take more than 10% of JASM. Then, in February 2024, TSMC publicly disclosed the post-expansion ownership structure: TSMC 86.5%, Sony 6.0%, Denso 5.5%, Toyota 2.0%. That directly contradicts the article’s claim that JASM was a venture founded with ownership of 70% / 20% / 10%.

The sentence says TSMC’s 100% renewable-energy target is on the same 2050 timeframe as its net-zero target. But TSMC’s 2025 annual report gives different dates: it says the company is targeting 100% renewable energy by 2040 and net-zero emissions by 2050. So tying both goals to the same 2050 deadline is incorrect.

TSMC’s published 2025 annual report states: “In US dollar terms, TSMC generated net income of US$55.21 billion on consolidated revenue of US$122.42 billion.” That directly contradicts the infobox figure of US$55.13 billion.

TSMC’s 2025 annual report says the second Arizona facility has completed construction and that TSMC expects it to enter high-volume manufacturing in the second half of 2027. That contradicts the article’s statement that production is in 2028.
