Insights

Financial Analyst

TL;DR Insider sales under a pre-established 10b5-1 plan; transaction sizes are modest relative to institutional levels.

The reporting shows routine disposition of common shares via a 10b5-1 plan adopted June 13, 2025. Two blocks totaling 4,000 shares were sold on September 12, 2025 at weighted-average prices of $68.3618 and $69.1478, reducing direct beneficial ownership to 97,809 shares. The filing discloses participation in the company ESPP and a retirement account which form part of the reported holdings. From a financial-materiality perspective, the sale appears administrative and structured under a trading plan; the filing does not indicate acceleration, option exercises, or derivative activity.
