Routine Form 144 selling notice showing multiple dispositions.

The filing lists successive sales of Common stock recorded as Restricted Stock with transactions clustered between 02/23/2026 and 05/11/2026. The largest single listed disposition is 4,737 shares on 03/17/2026.

Equity Capital Markets Specialist

Multiple small-to-moderate share disposals; no material company-level impact shown.

The sequence of mostly 1,200-share transactions and one 4,737-share trade suggests staged dispositions by the holder. Each row includes a dollar amount tied to the trade but the excerpt does not state aggregated totals or market impact.

Subsequent filings or broker reports would be needed to confirm sale methods and any effect on float.

Restricted Stock financial

"Common | 03/15/2023 | 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.

Form 144 regulatory

"form_type: 144 (header metadata and context)"

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.
