Insights

Corporate Insider Trading Analyst

TL;DR: Insider trades under a 10b5-1 plan reduced holdings to 202,641 shares while exercising options at $3.7898.

The reporting person executed a set of planned transactions on 10/06/2025 and 10/07/2025 under a Rule 10b5-1 plan adopted on 02/12/2025, acquiring option rights and selling common shares. The sales were done in multiple tranches at weighted-average prices reported near $18.06.

Execution under an established 10b5-1 plan reduces timing risk and indicates trades were pre-authorized; investors may monitor any subsequent Form 4s for additional planned sales or option exercises and watch vesting milestones tied to the 08/08/2023 vesting schedule for the underlying options.
