Key Terms

weighted average purchase price, beneficial ownership, pecuniary interest, ten percent owner

4 terms

weighted average purchase price financial

"The reported price in Column 4 is a weighted average purchase price."

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

"shall not be construed as an admission that any such Reporting Person is the beneficial owner"

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 of all equity securities reported herein except to the extent of its respective pecuniary interest"

ten percent owner regulatory

"each indicated as a ten percent owner of ProFrac Holding Corp."
