Vistra Corp. (VST) has undergone a remarkable financial transformation over the past several years, evolving from a company posting operating losses in 2021 and 2022 into one of the more profitable independent power producers in the U.S. today. Revenue has grown at a steady mid-to-high single-digit pace, margins have expanded dramatically, and the most recent quarter (Q1 2026) shows the momentum continuing — with operating margins above 26% and a healthy EBITDA of nearly $2 billion in just one quarter. The main caveats are a balance sheet that carries meaningful leverage (debt-to-equity near 3.5x), a current ratio consistently below 1.0 in recent periods suggesting tight near-term liquidity, and capital expenditures that are rising sharply as Vistra invests aggressively in capacity — likely tied to the surging demand picture from data centers and AI infrastructure. On balance, Vistra looks like a business in a strong earnings cycle, but investors should keep a close eye on its debt load and escalating reinvestment needs.
Snapshot & Big Picture
Vistra Corp. is a Texas-based integrated retail electricity and power generation company, one of the largest competitive power producers in the United States. Its generation fleet spans natural gas, nuclear, coal, solar, and battery storage assets, giving it diversified exposure to wholesale power markets. After emerging from bankruptcy in 2016, Vistra spent its early years as a public company navigating volatile commodity markets, which showed up in erratic earnings. The 2021–2022 period was particularly painful — operating margins were deeply negative, and EBITDA cratered to just $238 million and $419 million respectively, partly reflecting cost pressures and the aftermath of Winter Storm Uri. Since then, the story has reversed sharply: higher power prices, the acquisition of Energy Harbor (which added significant nuclear capacity), and operational improvements have driven EBITDA from under half a billion dollars to nearly $6 billion at peak in fiscal 2024.
| Fiscal Year | Revenue | EBITDA | Operating Margin | Net Margin |
|---|---|---|---|---|
| 2017 | $5.43B | $897M | 3.6% | -4.7% |
| 2018 | $9.14B | $1.89B | 5.4% | -0.6% |
| 2019 | $11.81B | $3.63B | 16.9% | 7.9% |
| 2020 | $11.44B | $3.26B | 13.3% | 5.6% |
| 2021 | $12.08B | $238M | -12.5% | -10.5% |
| 2022 | $13.73B | $419M | -8.6% | -8.9% |
| 2023 | $14.78B | $4.16B | 18.0% | 10.1% |
| 2024 | $17.22B | $5.92B | 23.7% | 15.4% |
| 2025 | $17.74B | $3.89B | 10.7% | 5.3% |
One notable data point worth flagging: gross margin figures were not available in the filings provided for any period, so profitability analysis here relies on operating and net margins alongside EBITDA.
Latest Quarter Snapshot (Q1 2026)
The most recent data — more current than the annual figures — comes from Vistra's 10-Q filed May 8, 2026, covering the quarter ended March 31, 2026. This single quarter paints a strong picture:
| Metric | Q1 2026 |
|---|---|
| Revenue | $5.64B |
| EBITDA | $1.98B |
| Operating Margin | 26.6% |
| Net Margin | 18.2% |
| Current Ratio | 0.90x |
| Debt-to-Equity | 3.42x |
| Capital Expenditures | $883M |
| CapEx as % of Revenue | 15.7% |
Q1 2026 operating margins of 26.6% are actually higher than the full-year 2025 figure of 10.7%, which signals that fiscal 2025's lower margins may have been weighed down by specific items (such as hedging losses, one-time costs, or seasonal factors) rather than a structural deterioration. The quarterly run rate, if sustained, would imply annualized revenue approaching $22–23 billion — a meaningful step up from the $17.7 billion reported in full-year 2025.
Profitability
Vistra's profitability history is genuinely volatile, reflecting the commodity-driven nature of power markets. The early years (2017–2018) were barely profitable at the operating line and loss-making at the net income level. The company found its footing in 2019–2020, posting respectable margins, only to be hammered in 2021–2022 by extraordinary events and cost headwinds. The recovery since 2023 has been sharp: operating margins went from deeply negative to 18%, then 23.7% in 2024 — a multi-year high. Fiscal 2025 saw a pullback to 10.7% operating margin and 5.3% net margin, which bears watching, though the Q1 2026 data suggests the business may have recovered from whatever weighed on the full-year 2025 results. EBITDA peaked at $5.92 billion in 2024 before declining to $3.89 billion in 2025; the $1.98 billion Q1 2026 EBITDA suggests the year is off to a strong start.
Financial Health
Vistra's balance sheet has shifted meaningfully in recent years. Through 2021, the company carried virtually no net debt relative to equity (debt-to-equity was reported as zero in both 2020 and 2021). That changed with the Energy Harbor acquisition and ongoing capital investment — by fiscal 2025, debt-to-equity stood at 3.70x, and the most recent quarter shows it at 3.42x. This is elevated leverage for any industrial company, though not unusual for capital-intensive utilities and power producers that generate consistent operating cash flow. The more pressing near-term flag is liquidity: the current ratio has slipped below 1.0x in fiscal 2025 (0.78x) and remains there in Q1 2026 (0.90x), meaning current liabilities exceed current assets. This warrants monitoring, particularly if credit markets tighten or commodity markets turn.
Capital Expenditures: CapEx is rising rapidly and is a defining feature of Vistra's current investment phase. Annual capex has climbed from $530 million in 2018 to $1.30 billion in 2022, $1.68 billion in 2023, $2.08 billion in 2024, and $2.75 billion in fiscal 2025 — a more than fivefold increase over seven years. As a share of revenue, capex has risen from roughly 6% in 2018–2019 to over 15% in fiscal 2025 and Q1 2026. This signals that Vistra is in an aggressive reinvestment cycle, almost certainly tied to expanding its generation capacity — nuclear life extensions, battery storage buildout, and potentially new gas or clean energy projects to serve data center and AI-driven power demand. High and rising capex is a double-edged sword: it can drive future earnings if demand materializes as expected, but it also pressures free cash flow and requires continued access to capital markets at manageable rates.
| Period | Capital Expenditures | CapEx / Revenue |
|---|---|---|
| FY 2018 | $530M | 5.8% |
| FY 2019 | $713M | 6.0% |
| FY 2020 | $1.26B | 11.0% |
| FY 2021 | $1.03B | 8.6% |
| FY 2022 | $1.30B | 9.5% |
| FY 2023 | $1.68B | 11.3% |
| FY 2024 | $2.08B | 12.1% |
| FY 2025 | $2.75B | 15.5% |
| Q1 2026 | $883M | 15.7% |
Growth
Vistra has grown revenue consistently over the periods for which CAGR data is available. The 10-year window is not calculable — Vistra's SEC filing history does not extend back a full decade with comparable data, so that figure is unavailable.
| Window | Start Year | End Year | Start Revenue | End Revenue | CAGR |
|---|---|---|---|---|---|
| 3-Year | FY 2022 | FY 2025 | $13.73B | $17.74B | 8.9% |
| 5-Year | FY 2020 | FY 2025 | $11.44B | $17.74B | 9.2% |
| 10-Year | N/A | N/A | N/A | N/A | Not available — insufficient filing history |
The 3-year and 5-year CAGRs are remarkably consistent at roughly 9%, suggesting Vistra has compounded revenue at a solid pace through both the difficult 2021–2022 period and the subsequent recovery. Given the Q1 2026 quarterly run rate, there is a reasonable possibility that the 3-year CAGR measured from fiscal 2023 onward will accelerate further if current earnings momentum holds.
