Insights

Insider trading and corporate governance analyst

Routine executive option exercise and share sale, with holdings still remaining.

The EVP and Chief Administrative Officer of Vistra Corp. exercised 2020 employee stock options on 11/14/2025 to buy 58,275 options worth of common stock at an exercise price of $22.98 per share, then sold the same number of shares at a weighted-average price of $174.75. This combination of a transaction code M (option exercise) and S (sale) is a common pattern for monetizing vested equity awards.

After the transactions, the executive still held 218,239 shares of common stock directly and no remaining derivative securities from this specific option award, which had vested in three annual installments starting on February 25, 2021. The price disclosure as a weighted average, with trades between $174.62 and $175.19, indicates multiple market trades rather than a single block. As described, this appears to be a standard compensation-related liquidity event rather than a change in control or strategy signal.
