[144] Vistra Corp. SEC Filing

Rhea-AI Filing Summary

Vistra Corp. (VST) submitted a Form 144 notice describing a proposed sale of 21,376 shares of common stock by a holder with broker Fidelity Brokerage Services LLC, with an aggregate market value of $4,307,029.31 and an approximate sale date of 10/07/2025. The filing shows the securities were acquired under an option granted on 04/09/2018 and that payment at sale is expected in cash.

The filing also lists multiple prior disposals by the same seller, James A. Burke, between 09/10/2025 and 10/06/2025, with daily lot sizes generally around 21,000–43,000 shares and gross proceeds per trade in the multi‑million dollar range. The seller certifies no undisclosed material adverse information and references Rule 10b5‑1 language in the remarks.

Positive

• Full disclosure of proposed sale including share count 21,376 and market value $4,307,029.31
• Acquisition details provided: securities were from an option granted 04/09/2018
• Broker identified as Fidelity Brokerage Services LLC, supporting traceability of the trade

Negative

• No explicit Rule 10b5‑1 adoption date is provided, so it is unclear whether sales follow a documented trading plan
• Frequent recent insider sales (multiple disposals from 09/10/2025 to 10/06/2025) increase near‑term share supply

Insights

Insider Transactions Specialist

Insider plans continued structured sales over recent weeks, indicating systematic liquidation.

The filing documents a proposed sale of 21,376 shares valued at $4,307,029.31 on 10/07/2025

Multiple prior sales by the same individual between 09/10/2025 and 10/06/2025 show recurring daily dispositions in similar lot sizes, consistent with a programmed or rule‑based selling approach. Investors should note this pattern when assessing potential share supply over the near term.

Corporate Governance Analyst

Disclosure complies with Rule 144 mechanics and includes required representations.

The filer identifies the acquisition as an option grant dated 04/09/2018 and certifies the absence of undisclosed material adverse information. The notice names the executing broker as Fidelity Brokerage Services LLC.

Signatures and the explicit Rule 10b5‑1 language are present; absent are any statements about a formal trading plan adoption date, so the filing does not confirm a documented plan date.
