FAQ

What insider transaction did TSM VP Shyue-Shyh Lin report?

Shyue-Shyh Lin, a vice president of Taiwan Semiconductor, reported buying 3,000 common shares on July 19, 2026. The purchases were split into three 1,000-share open-market or private transactions, each reported with a specific U.S. dollar price translated from New Taiwan dollars.

How many TSM (TSM) shares did Lin buy and at what prices?

Lin acquired 3,000 common shares in three separate 1,000-share trades. The reported per-share prices were US$72.10, US$71.32, and US$71.94, each translated from New Taiwan dollar amounts using a stated foreign exchange rate.

Does Shyue-Shyh Lin hold any TSM shares indirectly?

Yes. The filing reports 5,000 common shares held indirectly "By Spouse" and an additional 249 common shares held indirectly "By ESPP Trust." These positions are separate from the directly purchased shares and reflect different forms of beneficial ownership.

Were Shyue-Shyh Lin’s TSM trades under a Rule 10b5-1 plan?

The filing’s Rule 10b5-1 checkbox is not marked, and no footnote states the trades were made under a Rule 10b5-1 trading plan. The transactions are therefore reported without affirmation that they followed a pre-arranged trading program.

What FX rate was used for Lin’s TSM share purchases?

For each transaction, prices in New Taiwan dollars were translated at NT$32.248 to US$1. Footnotes specify NT$2,325, NT$2,300, and NT$2,320 per share for the three trades, which correspond to the reported U.S. dollar per-share prices.
