subscription agreement financial

"the issuer entered into a subscription agreement with the reporting person for a $100,000 investment"

A subscription agreement is a legal contract in which an investor agrees to buy a specific number of a company’s shares or other securities under set terms, including price, payment method and conditions for closing the sale. It matters to investors because it legally locks in their purchase and the company’s obligations, determines ownership percentage and any investor rights, and can include conditions or promises that affect future control or returns—like signing a detailed purchase order for equity.

volume-weighted average price (VWAP) financial

"The shares were valued at the volume-weighted average price (VWAP) of the issuer"

Volume-weighted average price (VWAP) is the average price of a security over a trading period where each trade’s price is weighted by how many shares were traded, so larger trades pull the average more than tiny ones. Investors and traders use VWAP as a benchmark to judge whether a trade was executed at a favorable price—similar to checking whether you paid more or less than the typical price when most people were buying or selling.

open-market purchase financial

"transaction_action": "open-market purchase""

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.
