Vistra Corp. (VST) shares climbed sharply during a holiday-shortened trading week, reflecting sustained investor enthusiasm for power producers tied to artificial intelligence data centers. The stock closed at $163.75 on Thursday, up 3.1% for the session, after reaching an intraday high of $170.34. Volume was robust at around 8 million shares. Markets were closed Friday for Juneteenth and remained shut through the weekend, making Thursday the last trading day until Monday.
The week's gains amounted to approximately 10.6% from the prior Friday's close of $148.02, as buyers continued to pile into names benefiting from the surging electricity needs of AI infrastructure. This move aligns with a broader rally in utility and power stocks, with peers such as Constellation Energy rising 2.6% and Talen Energy adding 6.4% in the final session. The broader market also advanced, with the SPDR S&P 500 ETF up 0.8% and the Utilities Select Sector SPDR Fund rising 0.7%.
A key catalyst for Vistra was the launch of Helix Digital Infrastructure, a KKR-backed venture announced last week with over $10 billion in committed capital. Founding partners include KKR, the Kuwait Investment Authority, Nvidia, and Vistra itself. Vistra will serve as the preferred power supplier for the venture, positioning the Texas-based company closer to hyperscale cloud and data-center operators. Helix CEO Adam Selipsky, former head of Amazon Web Services, noted that large digital infrastructure users face an "urgent need" to simplify projects and scale capacity. Vistra CEO Jim Burke described power generation and grid connections as "critical gating factors" for scaling AI operations, while Nvidia's Jensen Huang highlighted extraordinary demand for "AI factories."
Beyond the AI narrative, Vistra's first-quarter financials underscore its operational strength. The company reported net income of $1.03 billion and ongoing operations adjusted EBITDA of $1.49 billion. Adjusted EBITDA, a non-GAAP measure that excludes interest, taxes, depreciation, and other items, is a key metric for the firm. Vistra maintained its full-year 2026 ongoing operations adjusted EBITDA forecast in the range of $6.8 billion to $7.6 billion.
Analysts have remained largely bullish. According to TipRanks, Goldman Sachs' Carly Davenport reiterated a Buy rating on June 18 with a $209 price target. Seaport Global's Angie Storozynski raised her target to $230 on June 15. Morgan Stanley's David Arcaro also maintained a Buy with a $212 target on June 12, citing upside from the Helix partnership.
A notable technical event looms on Monday: Vistra shares will trade ex-dividend. Investors purchasing the stock on or after June 22 will not receive the next quarterly payout of $0.2290 per share, which is scheduled for June 30. To qualify for the dividend, buyers must be on record as of June 22.
Despite the positive momentum, risks remain. Vistra's guidance excludes potential contributions from the Cogentrix acquisition and long-term power contracts with Meta, which could influence actual results. The company noted that performance will depend on power prices, hedging strategies, and other variables. A slowdown in AI spending, permitting challenges, plant outages, or lower power prices could weaken the bullish thesis.
