Form 144 regulatory

"Form 144 notice for the proposed sale of 6,000 shares"

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.

Rule 144 regulatory

"proposed sale under Form 144 notice (implied regulatory context)"

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.

shares outstanding financial

"51,459,766 as of 06/01/2026"

Shares outstanding are the total number of a company’s stock units held by all shareholders, including institutional investors and company insiders — think of them as the total number of slices of the company’s ownership pie. Investors use this number to calculate how much of the company each share represents, and it directly affects per-share measures like earnings per share, ownership percentage and valuation; when the slice count changes, an investor’s claim and the company’s per-share metrics change too.
