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.

FAQ

What insider transaction did TSM SVP Hou Yung-Chin report on this Form 4?

Hou Yung-Chin reported a small employee-plan purchase of common shares. An administrator of Taiwan Semiconductor’s Employee Stock Purchase Plan bought 61 common shares on his behalf, at $76.62 per share, under predetermined ESPP terms rather than a discretionary open-market decision.

How many Taiwan Semiconductor (TSM) shares were bought for Hou under the ESPP?

A total of 61 common shares were purchased for Hou under the Employee Stock Purchase Plan. These shares were acquired on July 7, 2026, at $76.62 per share and are held indirectly through an ESPP trust associated with Taiwan Semiconductor’s plan structure.

What are Hou Yung-Chin’s total indirect holdings in TSM after this transaction?

After this transaction, Hou’s indirect holdings include 7,397 shares via the ESPP trust, 60,802 shares held by a spouse, and 20,190 shares held by a Long-Term Incentive bonus plan trust, reflecting several indirect ownership channels in addition to his direct share position.

How many Taiwan Semiconductor (TSM) shares does Hou hold directly after the Form 4 transaction?

Following the reported activity, Hou holds 662,403 common shares directly. This direct position is separate from his indirect holdings through his spouse, the Long-Term Incentive bonus plan trust, and the ESPP trust that acquired 61 additional shares on his behalf.

Was the TSM share purchase by Hou Yung-Chin a pre-planned ESPP transaction?

Yes. Footnotes explain the common shares were bought by the Employee Stock Purchase Plan administrator under terms predetermined by Taiwan Semiconductor. This indicates the 61-share acquisition followed preset ESPP rules rather than an opportunistic market-timing decision by Hou.

At what exchange rate was the Taiwan Semiconductor ESPP purchase price translated?

The share price reflects an average purchase price of NT$2,462.6361 translated at NT$32.143 to US$1. This conversion produced the reported $76.62 per share figure for the 61 common shares bought under the Employee Stock Purchase Plan on Hou’s behalf.
