weighted average purchase price financial

"Represents the weighted average purchase price. The Shares were purchased at prices"

The weighted average purchase price is the average cost per share you paid across multiple buys, calculated so larger purchases count more than smaller ones. Imagine buying apples at different prices: the overall price you effectively paid depends on how many apples you bought at each price. Investors use it to measure true cost basis, calculate gains or losses, decide when to sell, and manage taxes and portfolio performance.

beneficial ownership regulatory

"of which Reporting Person disclaims beneficial ownership except to the extent"

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

"beneficial ownership except to the extent of his pecuniary interest, if any"

immediate family other

"Includes shares of common stock held by certain members of Reporting Person's immediate family"

indirect financial

"HCWG is the direct holder of such shares."
