Employee Stock Purchase Plan financial

"Common Shares purchased by the administrator of the issuer's Employee Stock Purchase Plan ("ESPP") on behalf of the filer"

An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.

Long-Term Incentive ("LTI") Bonus Plan financial

"Represents Common Shares purchased by a trust with cash received under the issuer's Long-Term Incentive ("LTI") Bonus Plan"

Equity Linked Notes financial

"The Equity Linked Notes are issued by UBS AG that reference a basket of equity securities that includes the issuer's American Depositary Shares"

American Depositary Shares financial

"Each American Depositary Share represents five (5) Common Shares."

American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.

initial reference level financial

"The strike price for each basket component equals 70% of its initial reference level."

strike price financial

"If the issuer's American Depositary Shares are determined to be the worst-performing basket component, settlement may result in delivery of up to 636 American Depositary Shares of the issuer at a strike price of 235.697 per American Depositary Share."

The strike price is the fixed price at which an option gives its holder the right to buy or sell an underlying stock. Think of it like a coupon that lets you transact at a pre-agreed price regardless of the market; for investors it determines whether an option will be profitable, influences potential gains or losses, and is a key factor in the option’s market value and risk profile.

FAQ

What insider transaction did TSM executive Yuh-Jier Mii report?

TSMC EVP and Co-COO Yuh-Jier Mii reported a small insider purchase of 75 Common Shares on May 8, 2026 through the company’s Employee Stock Purchase Plan, executed by the ESPP administrator on his behalf at an average price of $71.82 per share.

How many Taiwan Semiconductor (TSM) shares does Yuh-Jier Mii hold after this Form 4?

After the reported transactions, Yuh-Jier Mii directly holds 1,254,057 Common Shares and 25 American Depositary Shares, plus 7,887 Common Shares via the ESPP trust and 63,345 Common Shares via an LTI trust, reflecting a large existing ownership position relative to the new purchase.

What is the nature of the 75 TSM Common Shares recently acquired?

The 75 Common Shares were purchased by the administrator of Taiwan Semiconductor’s Employee Stock Purchase Plan under predetermined terms, on behalf of Yuh-Jier Mii. These ESPP purchases are compensation-related and represent a routine, modest increase in his indirect ownership through the ESPP trust.

What are the Equity Linked Notes disclosed in the TSM Form 4?

The filing shows Equity Linked Notes issued by UBS AG referencing a basket that includes TSM ADRs. Depending on performance and redemption conditions, each note may settle in up to 636 or 703 TSM ADRs or cash at exercisable dates in 2026 and 2027, subject to basket pricing.

How are TSM American Depositary Shares related to its Common Shares?

Each Taiwan Semiconductor American Depositary Share represents five Common Shares, according to the footnotes. This means ADR holdings and potential ADR settlement from the Equity Linked Notes correspond to multiples of underlying TSM Common Shares, linking U.S.-traded and Taiwan-listed securities.

Is the reported TSM insider transaction a buy or sell event?

The Form 4 reflects a net-buy event. It records an open-market style purchase of 75 Common Shares via the Employee Stock Purchase Plan, with no reported open-market sales, so the overall direction of this filing is a small increase in Yuh-Jier Mii’s TSM equity exposure.
