Insights

Corporate Insider Transactions Analyst

Planned sale by an insider after multiple recent disposals; material to short-term supply.

The filing records a proposed sale of 193,905 shares on 10/08/2025 and lists recent open-market sales by the same person totaling 581,715 shares across five trades. Large, sequential insider sales can increase available float and add selling pressure in the near term if executed on market.

Dependencies include actual execution timing and whether sales are part of a pre-arranged plan; the filing affirms the signer does not possess undisclosed material information. Watch trading notices and market volume over the coming days for observable price impact.

Equity Compensation Specialist

Equity awards supplied shares for sale; two award dates and amounts are disclosed.

The table shows shares acquired via equity awards: 124,107 on 04/01/2024 and 69,799 on 09/29/2025, with payment indicated as cash. This documents the provenance of the securities being offered and satisfies disclosure of acquisition dates and amounts.

Key items to monitor are additional filings that would show whether future awards are subject to similar dispositions and any planned-trading statements that would clarify execution mechanics within Rule 144 compliance timelines.
