Insights

Financial Analyst

TL;DR: Significant insider dispositions reported: roughly 1.42 million shares sold across two days at ~ $2.01 weighted average.

The filings show Reprogrammed Interchange LLC sold 611,647 shares on 08/27/2025 and 806,351 shares on 08/28/2025, reducing its reported beneficial holdings from 37.69 million to 36.88 million shares. The disclosed weighted average prices were $2.0053 and $2.0115, with trade price ranges provided for both days. These are material volumes of common stock for a single reporting entity; the report is clear on quantities and price ranges but does not include proceeds totals or intent. For market impact assessment, one would compare the sold volume to daily average volume and outstanding float, information not included in this filing.
