  1. Each American Depositary Share represents five (5) Common Shares. Common Shares purchased and held under the issuer's Employee Stock Purchase Plan ("ESPP"). The Equity Linked Notes are issued by Goldman Sachs International that reference a basket of equity securities that includes the issuer's American Depositary Shares. The principal amount of the notes is US$20,000. The notes are exercisable and expire on June 3, 2026 (the "Exercisable Date"). Under the terms of the notes, if the notes are not redeemed early and the closing price of the worst-performing basket component is below its strike price on the Exercisable Date, the notes may be settled by delivery of shares or American Depositary Shares of that worst-performing basket component plus cash in lieu of any fractional share. [Continued in footnote 4] [Continued from footnote 3] The strike price for each basket component equals 72.30% of its initial reference level. If the issuer's American Depositary Shares are determined to be the worst-performing basket component, settlement may result in delivery of up to 71 American Depositary Shares of the issuer at a strike price of US$278.8973 per American Depositary Share. In addition, the notes may be redeemed for cash, (i) if, during the observation period prior to the Exercisable Date, the closing price of each basket component has reached its initial reference level at least once, or (ii) if the notes are not redeemed early and the closing price of the worst-performing basket component is at or above its strike price on the Exercisable Date. [Continued in footnote 5] [Continued from footnote 4] On April 24, 2026, during the observation period prior to the Exercisable Date, the notes were redeemed early for cash.

American Depositary Shares financial
"The Equity Linked Notes are issued by Goldman Sachs International that reference a basket of equity securities that includes the issuer's American Depositary 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.
Employee Stock Purchase Plan financial
"Common Shares purchased and held under the issuer's Employee Stock Purchase Plan ("ESPP")."
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.

"If the issuer's American Depositary Shares are determined to be the worst-performing basket component, settlement may result in delivery of up to 71 American Depositary Shares of the issuer at a strike price of US$278.8973 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 did TSM VP Bor-Zen Tien report in this Form 4 filing?

Bor-Zen Tien reported his current holdings and an early cash redemption of Equity Linked Notes. The filing lists direct and indirect positions in Common Shares and American Depositary Shares, and confirms the derivative notes tied partly to TSM ADS were redeemed for cash before expiration.

How many TSM shares does Bor-Zen Tien hold after the reported transactions?

The filing shows Tien directly holds 9,051 Common Shares and 70 American Depositary Shares. Indirectly, 53 Common Shares are held by an immediate family member and 101 Common Shares are held through an ESPP trust, reflecting a mix of personal and related-party ownership positions.

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

The Equity Linked Notes are instruments issued by Goldman Sachs International with a principal of US$20,000, referencing a basket of equities including TSM American Depositary Shares. They allowed potential share settlement depending on performance, but were ultimately redeemed early for cash instead of delivering any shares.

Were any TSM American Depositary Shares delivered under the Equity Linked Notes?

The notes could have been settled by delivering up to 71 American Depositary Shares of TSM if certain price conditions were met at expiration. Instead, the notes were redeemed early for cash on April 24, 2026, so no TSM ADS were delivered under this structure.

What does the Form 4 reveal about TSM’s Employee Stock Purchase Plan (ESPP)?

The filing notes that 101 Common Shares are held under TSM’s Employee Stock Purchase Plan through an ESPP trust. This indicates Tien has accumulated some of his stake by purchasing and holding shares via the company’s employee-focused share purchase program.

What is the relationship between TSM Common Shares and American Depositary Shares in this filing?

The footnotes state that each American Depositary Share represents five Common Shares. Tien’s position includes both Common Shares listed in Taiwan and American Depositary Shares, providing exposure through local shares and U.S.-traded depositary receipts backed by underlying equity.
