Restricted Stock regulatory

"Common | 05/20/2026 | Restricted Stock | ISSUER"

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

Issuer regulatory

"Common | 05/20/2026 | Restricted Stock | ISSUER"

Form 144 regulatory

"144: Filer Information"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

NYSE market

"05/22/2026 | NYSE 144: Securities To Be Sold"

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.
