VST Vistra Corp.
Price Chart
Executive Summary
Margaret Montemayor, an officer of Vistra Corp., filed a Form 144 on June 2, 2026, indicating intent to sell 4,600 shares of common stock with an estimated aggregate market value of $736,000. The shares were acquired through restricted stock vesting in November 2025 and March 2026. This is a routine insider sale of a relatively small portion of holdings, and the filing itself is an advance notice of intent, not a completed transaction.
Actionable Insight
This is a routine insider sale by an officer following restricted stock vesting. The dollar amount is immaterial relative to market cap. No immediate trading action warranted; monitor for any pattern of larger or more frequent insider sales in future filings.
