3 terms

weighted average price financial

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

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

open-market transactions financial

"These shares were purchased in multiple transactions at prices ranging"

Open-market transactions are purchases or sales of a company’s securities that take place on public exchanges rather than through private agreements. They matter to investors because these trades change the number of shares available, can move the stock price, and often signal management’s view of the company’s value—like a store restocking or clearing shelves, altering supply and the price shoppers see.

beneficial ownership financial

"full information regarding the number of shares purchased at each"

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.
