Rule 144 regulatory

"See the definition of "person" in paragraph (a) of Rule 144."

Rule 144 is a U.S. securities regulation that sets conditions under which restricted or insider-held shares can be legally resold to the public, such as required holding periods, availability of public information, limits on how much can be sold at once, and certain filing requirements. For investors it matters because it determines when previously locked-up shares can enter the market — like a release valve that can increase supply, affect share price, and signal insider intent.

aggregate market value financial

"Common | Merrill Lynch ... | 3000 | 74818 | 156125679 | 08/26/2026"

Aggregate market value is the combined price you would pay to buy all outstanding shares of a company or all companies in a group at current market prices — essentially the sum of each stock’s market capitalization. It matters to investors because it shows the overall size and weight of an investment or sector (like the total cost to buy every piece of a puzzle), helps compare scale across companies or markets, and influences index composition and risk exposure.

Stock Plan Activity financial

"Common | 08/24/2025 | Stock Plan Activity | Issuer | | | 347"

NYSE market

"156125679 | 08/26/2026 | NYSE"

A large, regulated marketplace where stocks and other securities are listed and traded, acting like a global auction house that matches buyers and sellers and helps determine share prices. It matters to investors because listing and trading there provide liquidity, price discovery, and regulatory oversight—making it easier to buy or sell holdings and giving companies a visible platform that can affect credibility and access to capital.
