American depositary share financial

"Each American depositary share represents one Class A ordinary share."

An American Depositary Share (ADS) is a U.S.-listed certificate that represents a specified number of shares in a foreign company, held by a custodian bank; it works like a receipt that allows U.S. investors to buy and trade foreign equity on American exchanges without dealing with another country’s markets. Investors care because ADSs make foreign stocks easier to access, improve liquidity and settlement in dollars, and can affect dividend payments, voting rights and regulatory oversight compared with buying the underlying foreign shares directly.

derivative security financial

"Conversion of derivative security"

A derivative security is a financial contract whose value comes from the price or performance of something else, such as a stock, bond, commodity, or market index. For investors it acts like an insurance policy or a wager: it can be used to protect against losses, lock in prices, or amplify gains and losses, so it can change a portfolio’s risk and potential return without owning the underlying asset directly.

Wang Yan acquired 6,250 ADSs on 2026-08-16 through the exercise or conversion of equity awards. Footnotes explain these ADSs were acquired from vested restricted shares, with each ADS representing one Class A ordinary share.

What are Wang Yan’s WEIBO Corp (WB) ADS holdings after the reported transactions?

The filing does not report any sales of ADSs. It shows a derivative conversion of 6,250 restricted shares and an acquisition of 6,250 ADSs, with no sale transaction codes or sell-share amounts disclosed in the structured data.

What is the relationship between WEIBO Corp (WB) ADSs and Class A ordinary shares in this Form 4?

The footnotes state that each American depositary share (ADS) represents one Class A ordinary share. The 6,250 ADSs acquired therefore correspond to 6,250 Class A ordinary shares, providing a one-to-one representation between ADSs and underlying shares.

Was Wang Yan’s WEIBO Corp (WB) transaction made under a Rule 10b5-1 trading plan?

The Rule 10b5-1 checkbox is unchecked, so the filing does not identify these transactions as made under a Rule 10b5-1 trading plan. No footnote indicates reliance on such a pre-arranged trading arrangement for the reported conversions.
