open-market transactions financial

"The shares were acquired in three separate open-market transactions on September 2, 2026"

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.

per-share purchase price financial

"The price reported in Column 4 represents the actual per-share purchase price"

Rule 10b5-1 trading plan regulatory

"No Rule 10b5-1 trading plan is reported for these transactions"

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.
