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 | Fidelity Brokerage Services LLC ... | 10000 | 227200.00 |"

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.

Open Market Purchase market

"Common | 02/13/2026 | Open Market Purchase | Issuer |"

An open market purchase is when a company buys its own shares on public stock exchanges the same way any investor would, rather than through a private deal. Investors care because these purchases reduce the number of shares available, can boost earnings per share and share price, signal that management thinks the stock is undervalued, and use company cash that might otherwise go to reinvestment or dividends — like a business quietly buying back its own tickets at the box office.

attorney-in-fact regulatory

"as attorney-in-fact for Joseph F. Casey"

An attorney-in-fact is the person or entity given legal authority through a power of attorney to act on behalf of another for specific tasks, such as signing documents, voting shares, or handling transactions. For investors, this matters because it lets a trusted representative make timely decisions or complete paperwork when the owner cannot, much like handing keys to someone to run errands on your behalf—so checks on scope and limits of that authority are important.
