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.

restricted stock award financial

"Common | 02/20/2026 | Restricted Stock Award | Issuer"

A restricted stock award is company shares given to an employee or executive that cannot be sold or fully owned until certain conditions—like staying with the company for a set time or hitting performance targets—are met. Think of it as a gift that only becomes yours after you fulfill specific obligations; for investors, these awards matter because they can increase the total shares outstanding when they vest, reveal how management is being paid and motivated, and create potential selling pressure when restrictions lift.

attorney-in-fact regulatory

"as agent and attorney-in-fact for John Pfeifer"

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.

common financial

"Common | 02/20/2026 | Restricted Stock Award | Issuer"

NYSE market

"61739749 | 09/11/2026 | 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.
