Insights

Insider Transactions Analyst

Insider selling is ongoing; 13,390 shares planned, 82,100 sold in prior 3 months.

Reported planned sale of 13,390 shares for $1,588,589.60 on 10/07/2025 follows four recent sales totaling 82,100 shares across 09/12/2025–10/06/2025. The shares were originally acquired as compensation on 05/27/2016 and will be sold via a broker, indicating standard liquidity transactions rather than purchases.

Primary dependency is market execution and share count; monitor aggregate insider sales against outstanding 49,901,487 shares for near-term float impact and any further scheduled filings over the next 30 days.

Compliance Counsel

Form 144 disclosure follows Rule 144 mechanics and includes a 10b5-1 attestation clause.

The filing documents the acquisition method (stock options) and a cashless exercise/same-day sale payment, and includes the signature representation that no material nonpublic information is known. The form references Rule 10b5-1 plan adoption or instructions but does not list a plan adoption date in the shown fields.

Given those entries, confirm whether a written trading plan exists and its adoption date if relying on 10b5-1; any plan date would clarify affirmative safe-harbor reliance within the filing record.
