Vistra Corp. stock (NYSE: VST) finished Friday, December 19, 2025 at $164.10, down 1.25% on the day, capping a volatile stretch in which investors have been repricing “AI power demand” winners and losers almost in real time. In the last few sessions alone, VST swung from a sharp selloff to a rebound and then back to a modest pullback—an illustration of how crowded (and headline-sensitive) the independent power producer trade has become. [1]
But under the surface, Vistra remains in the spotlight for reasons that go beyond day-to-day market noise:
- A record-setting PJM capacity auction has improved forward revenue visibility for owners of existing generation, including Vistra.
- A major federal regulatory move on data center “co-location” in PJM could reshape how hyperscalers and power plant owners contract for electricity.
- Investment-grade credit status and higher 2026 earnings guidance have reinforced the company’s “scale + cash flow + capital returns” narrative.
Here’s the full picture of the latest Vistra stock news, forecasts, and key catalysts as of 19.12.2025.
Vistra stock price today: where VST stands on Dec. 19, 2025
VST closed at $164.10 on Dec. 19, with an intraday range of roughly $164.01 to $171.41 and volume near 3.8 million shares, according to historical pricing data. [2]
Even after the pullback, Vistra is still trading below its recent peak: MarketWatch data earlier this week showed a 52-week high around $219.82, underscoring how far the stock had run before the latest bout of profit-taking and narrative whiplash. [3]
What Vistra does—and why investors care about its asset mix
Vistra describes itself as a Fortune 500 integrated retail electricity and power generation company headquartered in Irving, Texas, serving customers across multiple U.S. markets. The company operates a diversified generation fleet that includes natural gas, nuclear, coal, solar, and battery energy storage, alongside a retail electricity business. [4]
That combination matters right now because Wall Street is paying a premium for power platforms that can offer:
- Dispatchable generation (especially gas and nuclear) to meet rising load,
- Regional exposure to the tightest power markets, and
- Contracting pathways to monetize demand growth from data centers and electrification.
Catalyst 1: PJM capacity auction shocker boosts forward revenue visibility
The single biggest near-term headline driver for many PJM-exposed power producers has been PJM Interconnection’s latest Base Residual Auction (BRA) for the 2027/2028 delivery year.
PJM auction results: record price at the cap, and a supply shortfall
PJM announced it procured 134,479 MW of unforced capacity generation and demand response. The clearing price hit $333.44/MW-day, which PJM stated was the FERC-approved cap for the entire PJM footprint. PJM also said cleared capacity was short of its reliability requirement by 6,623 MW, and noted that forecast peak load for 2027/2028 was about 5,250 MW higher than the prior year’s forecast—nearly 5,100 MW of that increase tied to data center demand. [5]
Reuters separately reported that PJM capacity prices have surged by roughly 1,000% over about two years, intensifying affordability concerns even as the high prices aim to attract new supply. [6]
Vistra’s PJM “clear” is big—and the company disclosed the exact numbers
In a Dec. 17 Form 8‑K filing, Vistra reported it cleared approximately 10,566 MW in the PJM auction at a weighted average clearing price of $333.44/MW-day, with cleared MW broken out across PJM zones. [7]
Industry analysts quickly translated that into a major forward cash flow opportunity. Utility Dive reported that Vistra’s cleared capacity “will generate” about $1.3 billion in capacity revenue for the 2027/2028 capacity year, based on SEC filings and the auction price. [8]
Why this matters for VST stock: capacity payments are not the same as energy sales, but they can provide durable, forward-committed revenue that improves planning confidence—especially valuable in a market where demand growth is racing ahead of new supply.
The catch: the same auction outcomes that help generators can feed a political and regulatory backlash if customer bills rise sharply. Reuters highlighted concerns about affordability and referenced governors pushing for continued price limits. [9]
Catalyst 2: FERC’s data center co-location order could change the game in PJM
On the regulatory front, Vistra is also tied to a major Washington story unfolding right now: how the grid should handle data centers and other large loads co-located at power plants.
What FERC ordered
On Dec. 18, 2025, the Federal Energy Regulatory Commission (FERC) said it directed PJM to establish transparent rules to facilitate service of AI-driven data centers and other large loads co-located with generating facilities, emphasizing consumer protection and reliability across PJM’s footprint (serving more than 67 million people across 13 states and D.C.). [10]
FERC also said it found PJM’s tariff unjust and unreasonable due to lack of clarity around rates, terms, and conditions for customers serving co-located load, and directed PJM to revise its tariff so eligible customers serving co-located load choose among several transmission service options. FERC further directed PJM to report by Jan. 19, 2026 on proposals to speed new capacity additions, including expedited interconnection for shovel-ready projects and enhanced load forecasting. [11]
Reuters characterized the decision as a step aimed at protecting consumers while addressing reliability and cost concerns tied to AI-driven load growth. [12]
Why this matters for Vistra (and why it’s showing up in analyst notes)
Utility Dive reported the decision was viewed as a win for independent power producers with gas and nuclear plants in PJM, explicitly naming Vistra among the beneficiaries cited by Capstone analysts. The article described FERC directing PJM to develop three transmission services for co-located loads and giving PJM 60 days to propose them. [13]
Bloomberg Law similarly reported Capstone analysts called the order a “major positive” for Vistra and other independent generators, pointing to pathways for expedited connections and revised tariffs for co-located loads. [14]
Investor takeaway: If co-location becomes more standardized and financeable inside PJM, owners of existing nuclear and gas assets could gain more direct routes to monetize hyperscale demand—potentially via contracts that improve cash flow visibility without waiting years for traditional interconnection queues to clear.
Catalyst 3: S&P upgrade to investment grade strengthens the “de-risking” narrative
Another key December tailwind: Vistra’s credit profile.
Investing.com reported that S&P Global Ratings upgraded Vistra to investment grade, raising its issuer credit rating to BBB- from BB+ with a stable outlook, citing improved long-term cash flow visibility through contracted cash flows and capacity revenues. The report also said S&P expected Vistra’s adjusted debt-to-EBITDA to be in the mid‑3x range by year-end 2025, falling to 2.6x–2.8x by 2026–2027. [15]
The same report linked the upgrade to Vistra’s Comanche Peak PPA announcement and the completion of the Lotus gas asset acquisition, and highlighted Vistra’s hedging and integrated retail model as mitigants to wholesale volatility. [16]
Why investment grade matters to VST stock: lower borrowing costs and wider investor eligibility can support a higher valuation multiple—especially for a capital-intensive power business that wants to keep building, contracting, and buying back stock.
Earnings outlook: Vistra’s 2026 guidance step-up is the backbone of the bull case
While auctions and regulation move the stock day-to-day, Vistra’s 2026 guidance remains the core fundamental anchor many investors are underwriting.
The latest guidance ranges
In its Nov. 6, 2025 earnings release, Vistra initiated 2026 Ongoing Operations Adjusted EBITDA guidance of $6.8 billion to $7.6 billion and Ongoing Operations Adjusted Free Cash Flow before Growth (FCFbG) of $3.925 billion to $4.725 billion. It also provided a 2027 midpoint opportunity for Ongoing Operations Adjusted EBITDA of $7.4 billion to $7.8 billion (not formal guidance, but framed as an opportunity). [17]
The company also said that as of Oct. 31, 2025 it had hedged about 98% of expected generation volumes for 2025, 96% for 2026, and 70% for 2027—supporting the guidance ranges and increasing visibility. [18]
Reuters reported the same 2026 EBITDA range and highlighted Vistra’s confidence in rising U.S. power demand, tying the outlook to portfolio expansion and growing load from AI and other electrification drivers. [19]
Q3 performance snapshot
For the quarter ended Sept. 30, 2025, Vistra reported net income of $652 million and Ongoing Operations Adjusted EBITDA of $1.581 billion, with the company attributing year-over-year improvement in part to higher realized energy/capacity prices and nuclear production tax credit revenue, partially offset by an outage impact. [20]
Growth plan: nuclear contracting + gas expansion to meet load growth
Vistra’s strategy has been to lock in longer-duration cash flows while expanding dispatchable capacity in constrained markets.
Comanche Peak nuclear PPA
Reuters reported Vistra signed a 20-year deal to supply 1,200 MW from its Comanche Peak nuclear plant, a deal that fits the “AI power demand” theme and also supports longer-term asset life economics. [21]
Vistra’s own earnings release similarly highlighted a 20-year PPA for 1,200 MW from Comanche Peak with an investment-grade counterparty. [22]
Natural gas build in the Permian Basin
Reuters reported Vistra planned to build two new natural gas units totaling 860 MW at its Permian Basin plant in West Texas, more than tripling the site’s capacity to 1,185 MW, in response to booming demand tied to households, businesses, and energy-intensive industries like data centers. [23]
Vistra reiterated that plan in its earnings release. [24]
Lotus acquisition adds 2,600 MW across multiple markets
Vistra’s expansion hasn’t been limited to greenfield builds. Reuters reported earlier in 2025 that Vistra agreed to acquire seven natural gas generation facilities totaling nearly 2,600 MW from Lotus Infrastructure Partners for $1.9 billion, aiming to meet rising power demand. [25]
By Q3, Vistra said it had completed the acquisition and characterized it as adding about 2,600 MW and expanding capabilities across Midwest, Northeast, and California markets. [26]
Capital returns: buybacks remain central, and the dividend is set for Dec. 31
Vistra has leaned heavily on capital returns as part of the equity story.
Buybacks
Vistra said that as of Oct. 31, 2025 it had executed about $5.6 billion in share repurchases since Nov. 2021, reducing shares outstanding by about 30% versus Nov. 2021 levels. The board also authorized an additional $1.0 billion in repurchases, and the company said roughly $2.2 billion remained available under authorization, expected to be completed by year-end 2027. [27]
Dividend
Vistra announced a quarterly dividend of $0.2270 per share of common stock, payable Dec. 31, 2025 to stockholders of record as of Dec. 22, 2025, with an ex-dividend date of Dec. 22, 2025. [28]
For income-focused investors, the dividend is still relatively modest compared with Vistra’s buyback program—but it adds another layer of shareholder return that can matter for certain mandates.
Vistra stock forecast: what analysts are projecting for VST
Analyst targets have remained notably bullish even after the stock’s big run—though dispersion is wide, reflecting uncertainty over how quickly demand growth converts to durable contracts.
- A Nasdaq/Fintel write-up tied to a KeyBanc initiation noted an average one-year price target around $236 (as of mid-November) and described a wide target range. [29]
- MarketBeat reported JPMorgan cut its price target to $233 from $249 while maintaining an overweight rating (as reported by other outlets), and said consensus targets clustered in the low-to-mid $200s. [30]
- StockAnalysis’ aggregated analyst page also placed the average target in the low $200s (with a broad high/low spread). [31]
How to interpret the “VST stock forecast” headline numbers:
Right now, the forecast debate is less about whether electricity demand is rising (most sources agree it is) and more about who pays, how fast new supply arrives, and how much of the upside Vistra can contract or hedge versus leaving exposed to volatile merchant pricing.
The biggest risks for Vistra stock going into 2026
Even with supportive catalysts, investors following Vistra Corp stock should keep a close eye on these pressure points:
- Affordability backlash in PJM: Record auction prices may boost generator economics, but they also raise the odds of political intervention and rule changes if consumer bills spike. [32]
- Regulatory complexity around data centers: FERC’s order is significant, but it initiates a process—PJM still has to propose and implement new tariff structures, and stakeholders will fight over cost allocation. [33]
- Texas grid policy is evolving too: Texas’ Senate Bill 6 and ERCOT’s posture on large loads underscore that data center growth can come with curtailment and compliance requirements—not just upside demand. [34]
- Operational risk: Outages (especially for nuclear) and execution risk on new builds can reshape earnings outcomes quickly in power markets. [35]
- Sentiment risk after a massive run: Reuters has noted how dramatically Vistra’s stock surged over the last two years, which raises the bar for “perfect execution” and can amplify drawdowns on any disappointment. [36]
What to watch next for VST stock
If you’re tracking Vistra into year-end and early 2026, the next major catalysts are likely to be:
- PJM’s implementation timeline following FERC’s Dec. 18 order (including PJM filings and next steps). [37]
- Follow-through from the PJM auction: how quickly the market capitalizes the 2027/2028 capacity economics and whether policy pushback grows. [38]
- Updates on contracting for large loads (data centers) and additional PPAs. [39]
- Capital allocation cadence: buybacks, balance sheet priorities post-upgrade, and any shift in dividend trajectory. [40]
