Rhea-AI Filing Summary

Vistra Corp (VST) EVP and CFO Kristopher E. Moldovan executed multiple transactions on June 17, 2025, as part of a pre-planned Rule 10b5-1 trading plan established on December 17, 2024.

• Exercise of 20,775 stock options at $22.98/share (2020 grant)

Following these transactions, Moldovan holds 167,154 shares directly. Both exercised option grants had previously vested in three equal annual installments from their respective grant dates. The transactions demonstrate a significant realization of gains given the substantial difference between the option exercise prices ($22.98-$26.56) and the sale price ($180.00).

Positive

• None.

Negative

• CFO Kristopher Moldovan executed a significant share sale of 34,944 shares at $180 per share (approximately $6.3 million), after exercising options at much lower prices ($22.98-$26.56), potentially indicating reduced confidence in near-term upside
