Insights

Securities Analyst

TL;DR: Substantial insider selling disclosed over recent weeks; planned sale is smaller and stems from option exercise.

The filing reports a proposed sale of 24,000 shares acquired by stock option exercise on 09/04/2025 for cash, valued at $1.44 million. Material context comes from prior disposals: four sales between 07/22/2025 and 08/28/2025 totaling 400,000 shares with gross proceeds of $22,902,000. While the current planned sale is routine following option exercise, the pattern of concentrated dispositions by the same individual over a short period can be relevant to market participants evaluating insider activity and share supply dynamics.

Corporate Governance Expert

TL;DR: Disclosure complies with Rule 144 format; signer affirms absence of undisclosed material information.

The Form 144 contains the required seller, broker and transaction details: broker identity, method of acquisition
