3 terms

initial public offering financial

"shares sold by the Reporting Person as a selling stockholder in the Issuer's initial public offering"

An initial public offering (IPO) is when a private company first sells its shares to the public and becomes a stock-listed company. It matters because it allows the company to raise money from a wide range of investors, helping it grow, while giving early shareholders a way to sell some of their ownership.

selling stockholder financial

"shares sold by the Reporting Person as a selling stockholder in the Issuer's initial public offering"

A selling stockholder is an individual or entity that owns shares of a company's stock and chooses to sell some or all of those shares to others. This often occurs when the owner wants to cash in on their investment or reduce their stake. For investors, understanding who the selling stockholder is can provide insights into potential changes in the company's ownership or market activity.

irrevocable trust financial

"Shares are directly held by an irrevocable trust, over which Matthew Alty has voting"

An irrevocable trust is a legal arrangement where an owner transfers assets into a separate entity managed by a trustee and gives up the power to modify or reclaim those assets. For investors it matters because putting stock or other holdings into such a trust can change who controls and benefits from the assets, affect taxes and creditor protection, and influence how easy it is to sell or value those holdings—like placing valuables in a locked safe overseen by someone else.
