Insights

Insider Transactions Analyst

TL;DR: Insider plans a modest sale of restricted shares acquired in 2024, executed through a broker in October 2025.

The transaction involves 8,333 common shares acquired via a restricted stock grant on 06/18/2024 and proposed for sale through Jefferies LLC with an aggregate value of $74,497.02. This is an individual holder sale rather than a company share issuance.

The sale size is small relative to the 62,000,000 shares outstanding, limiting direct market impact; the notice also affirms no other sales in the prior three months. Watch for the actual execution on 10/09/2025 and any 10b5-1 plan adoption date that would clarify whether the sale is pre-planned or discretionary.
