Insights

Securities Compliance Analyst

Form 144 lists multiple resale notices and past sales by the reporting address.

The filing records proposed resale(s) and reported sales of common stock, including a 4,737‑share sale on 03/17/2026 and many 1,200‑share transactions. These entries are formatted as resale notices and historical sales amounts.

Regulatory context: Form 144 is a notice required when restricted or control securities are sold in reliance on Rule 144; subsequent trading activity and timing depend on the holder and market mechanics, not disclosed here.

Equity Markets Specialist

Transaction pattern shows frequent, similarly sized dispositions over a three‑month span.

The sequence of many 1,200‑share entries plus one 4,737‑share block suggests staged sales rather than a single large block. Each row includes gross proceeds (e.g., $192,384.00), providing traceable per‑trade values.

Cash‑flow recipients and whether sales were brokered or private are not specified in the excerpt; subsequent filings would be required for execution method details.

Form 144 regulatory

"lists proposed and recent sales of restricted/common securities"

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.

Restricted Stock financial

"Common | 12/15/2022 | 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
