The Stock That Became a Proxy for the AI Power Trade

Vistra (VST) operates one of the largest competitive power generation fleets in the United States, with natural gas, nuclear, coal, and solar assets concentrated in Texas and the PJM interconnection region covering the mid-Atlantic and Midwest.

It sells electricity into wholesale markets, runs a retail electric business serving millions of customers, and has been expanding its nuclear capacity as a long-term growth investment. A year ago, most investors outside the energy sector could not have told you what Vistra was.

What changed is that the AI infrastructure buildout created a power problem, and Vistra happened to be sitting on part of the solution.

Data centers running AI workloads need enormous, continuous electricity, and nuclear generation produces exactly the kind of around-the-clock carbon-free power that technology companies are increasingly willing to pay premium prices to secure.

The stock ran from around $16 in early 2023 to a peak above $219 by late 2025, a move that reflected both a genuine shift in how the market values clean baseload power and a meaningful amount of enthusiasm getting priced in well ahead of the contracts.

The pullback has been real. VST hit a max drawdown of 25% in May and currently sits about 22% below the year’s high and 36% below the all-time peak. Some of that is normal multiple compression after an extraordinary run.

Some of it reflects genuine 2025 headwinds: the Moss Landing battery storage fire created operational disruptions and insurance accounting noise, and aggressive growth capital spending compressed reported free cash flow even while the underlying power business held up.

The Cash Flow Picture Is Messier Than the Story Suggests

Vistra’s reported free cash flow history looks volatile enough to give anyone pause. It was negative in 2021 and 2022 during heavy infrastructure investment, surged to $3.8 billion in 2023 when power prices were strong and margins were exceptional, then declined to $2.5 billion in 2024 and $1.3 billion in 2025 as growth capex accelerated and the Moss Landing situation created noise in the financials.

The 2026 guidance reframes the picture. Management is targeting adjusted free cash flow before growth of $3.76 to $4.56 billion for the full year, a substantial recovery from the 2025 figure.

Full-year adjusted EBITDA guidance sits at $6.72 to $7.52 billion, with the nuclear PTC benefit deliberately excluded from those numbers. A business generating $3.76 to $4.56 billion in adjusted FCF at a $47 billion market cap is not unreasonably priced if the guidance holds.

The Texas and East segments have both been strong, and the retail electricity business provides some earnings floor against the volatility of wholesale power prices.

Vistra is also in active discussions with data center customers around long-term power purchase agreements. The Comanche Peak nuclear facility adds generation capacity over time, and locking in PPAs at premium pricing above current spot rates would change the forward cash flow profile meaningfully.

What the TIKR Model Says About VST From Here

The TIKR valuation model mid case puts a price target of around $203 on VST over the next four years, implying roughly 9% annualized returns from current levels.

Revenue growth assumptions run at around 5% annually, net income margins expand toward 16%, and modest P/E compression of around 1% annually is baked in to account for the stretched multiple VST carried at its peak.

Nine percent annualized deserves to be said plainly for a stock that ran the way VST did. The model says the business keeps generating strong cash flow, the multiple compresses modestly, and investors earn a reasonable but unspectacular return.

The Street’s mean target of around $218 implies about 55% upside, a far more optimistic view that prices in additional data center contract wins and nuclear capacity value that the base model does not capture. The gap between the two reflects genuine disagreement about how much of the AI power narrative will translate into contracted revenue.

The longer-horizon mid-case forecasted return to 2034 reaches around 63% at roughly a 6% IRR.

Should You Buy VST Stock?

The bull case comes down to whether those data center PPAs get signed. If Vistra locks in long-term contracts at premium pricing with investment-grade technology customers, the adjusted FCF profile improves materially, the Street’s $218 target becomes more defensible, and the current price looks like an obvious entry.

At 14 times forward earnings with nuclear assets that are genuinely scarce, the stock is not expensive if the contracts come through.

The bear case is the gap between the narrative and what the model actually produces. A roughly 9% annualized mid-case return is not compelling for a stock with a beta of 1.43 and real operational complexity across multiple generation types, markets, and regulatory environments.

Moss Landing was a useful reminder that physical assets carry physical risks, and the FCF decline from $3.8 billion in 2023 to $1.3 billion in 2025 shows how fast the story can change.

Vistra is a real business riding a real trend, but the trade still depends on execution that has not fully materialized yet.
