open-market purchase financial
"The trust bought a total of 78,855 shares in open-market purchase transactions."
An open-market purchase is when an investor or a company buys shares on a public stock exchange at the going market price, rather than through a private deal. It matters to investors because these purchases change how many shares are available, can push the stock price up or signal confidence from large buyers, and often affect per-share metrics like earnings—think of it like someone buying lots of apples off a grocery shelf, reducing supply and potentially raising the price.
indirect ownership financial
"The newly purchased shares are reported as indirect ownership by Ernest Rady Trust."
pecuniary interest financial
"Rady disclaims beneficial ownership except to the extent of his pecuniary interest therein."
disclaims beneficial ownership financial
"The Reporting Person disclaims beneficial ownership of such shares."
Form 4 regulatory
