IRVING, Texas, September 5, 2026 at 5:55 a.m. CDT — Vistra Corp. NYSE:VST Chief Executive Jim Burke bought company shares worth $903,069. His 6,665 shares now sit 10.2% above their weighted-average cost.
The timing worked. The scale needs context. Burke’s SEC ownership filing shows that the purchases increased his total reported beneficial holdings by only about 0.54%.
Burke bought 2,200 shares on August 31 at a weighted average of $135.99. He added 4,465 on September 1 at $135.25. Both trades were coded as open-market purchases through JAMEB LP, which Burke and his spouse jointly own.
What Burke actually bought
Two open-market trades reported in the September 2 Form 4
At Friday’s close, the lot carried an estimated $92,015 paper gain. That is price arithmetic, before tax and transaction costs.

The trades followed an unusually weak month. Vistra closed at $155.94 on August 3 and $137.37 on August 31, a decline of 11.9%. Burke paid below the closing price on both purchase days.
Shares then rose for three straight sessions. Friday produced the largest step, a 3.5% gain to $149.30. Volume reached 4.6 million shares, close to recent daily norms.

The rebound has recovered part of the damage. Vistra still sits 32.1% below its 52-week high of $219.82. One well-timed insider trade cannot settle whether that discount is justified.
The ownership filing reports 1,146,352 shares held through the partnership after the purchases. Burke also reported 61,690 direct shares and 34,259 through two trusts. Together, those positions were worth about $185.5 million at Friday’s close.
The company’s buyback is the larger lever

The remaining corporate authorization is roughly 1,329 times Burke’s latest outlay. His trade is a signal; the buyback can alter per-share economics.
Company repurchase figures as of August 3: Vistra second-quarter release. Personal purchase value: SEC filing.
The corporate program carries more financial weight. Vistra said it had repurchased about $6.5 billion of shares since November 2021. Its share count had fallen roughly 30%, while $1.2 billion of authorization remained.
The operating case is substantial too. Vistra reported $1.77 billion of second-quarter adjusted EBITDA from ongoing operations, up 31% from a year earlier. It reaffirmed a 2026 range of $6.8 billion to $7.6 billion.
Management also kept adjusted free cash flow before growth guidance at $3.93 billion to $4.73 billion. The company had hedged almost all expected 2026 generation and 94% for 2027. Coverage falls to 72% for 2028.
Those hedges make the next two years less exposed to every wholesale-price swing. They do not remove execution risk. Vistra is buying Cogentrix and has committed up to $1 billion to Helix Digital Infrastructure.
Helix links Vistra with NVIDIA NASDAQ:NVDA, KKR & Co. NYSE:KKR and Kuwait Investment Authority. Burke said Vistra’s preferred-power role and the partnership “create an exciting opportunity for the company.” The release did not quantify Helix revenue.
The accounting can remain noisy. Second-quarter net income fell $22 million to $305 million, despite stronger adjusted EBITDA. Vistra attributed much of the gap to a $488 million increase in unrealized mark-to-market losses on derivatives.
The quarterly filing also describes exposure to commodity prices, collateral requirements, plant availability and regulation. Hedging shifts some risks across periods; it does not make them disappear.
Monday offers no price test because the NYSE is closed for Labor Day. Trading resumes Tuesday under the exchange’s 2026 holiday calendar. Any weekend power-market or deal news will meet the stock in one opening gap.
Burke’s purchase deserves attention for its timing, not its size. The harder investment evidence remains Vistra’s cash conversion, hedge roll-off and use of the remaining $1.2 billion buyback. Those figures can change value per share.
