Rule 10b5-1 trading plan regulatory

"sales reported in this Form 4 were effected pursuant to a Rule 10b5-1 trading plan"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

weighted average sale price financial

"The price reported above reflects the weighted average sale price."

beneficial ownership regulatory

"The Reporting Person disclaims beneficial ownership except to the extent of his and his spouse's pecuniary interest"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

pecuniary interest financial

"disclaims beneficial ownership except to the extent of his and his spouse's pecuniary interest therein"

indirect ownership financial

"Represents ordinary shares held by the Cheng Huang Family Trust"
