- Expected Volume Impact: Negligible.
- Sentiment Indicator: Neutral. Sales of founder shares for diversification are standard practice and do not necessarily indicate a lack of confidence in the company.

Transaction Notes
- 10b5-1 Plan: The reporting person adopted a trading plan on May 30, 2025, providing an affirmative defense against insider trading allegations.
- History: The filing notes multiple recent sales in late 2025 and early 2026 from various trusts (2020 Remainder Trust, 2015 Grat Remainder Trust), indicating a structured liquidation schedule.
