Insights

Securities Analyst

TL;DR: Officer sale of 4,166 shares under a 10b5-1 plan; remaining holding is 1,466,382 shares.

This Form 4 documents a routine disposition by an officer rather than a spontaneous market sale: the transaction was executed under a Rule 10b5-1 trading plan adopted May 16, 2025, and the reported trades occurred on 09/17/2025 at $2.50 per share in multiple executions. The disposed amount (4,166 shares) represents a very small fraction of the reported post-transaction ownership, suggesting the sale is not material to overall insider ownership levels.

Corporate Governance Expert

TL;DR: Disclosure aligns with standard insider-trading compliance; 10b5-1 plan cited.

The filing includes the required disclosure elements: reporting person identity and role, transaction date, transaction code, number of shares sold, execution price, and a statement that the sale was completed under a pre-established 10b5-1 plan. This provides transparency and indicates the transaction followed a pre-approved trading protocol. No indication of amendments or multiple reporting persons is present.
