Vistra Operations Company LLC has transformed from a money-losing power generator into one of the most profitable independent electricity producers in the United States. After posting net losses in 2021 and 2022 — years scarred by extreme weather events and commodity volatility — the company staged a dramatic recovery, generating over $2.6 billion in net income in 2024 on $17.2 billion in revenue. Revenue has grown at roughly 9% annually over both three- and five-year horizons, and the most recent quarter (ending June 2026) shows the business continuing to earn solid margins. The catch: Vistra is capital-hungry and increasingly leveraged, with debt-to-equity climbing sharply in recent years as the company invests heavily in new generation capacity — capex consumed over 22 cents of every revenue dollar in the latest quarter. Investors should weigh a genuinely strong earnings recovery and growing power demand tailwinds against rising financial leverage and aggressive reinvestment requirements.
Snapshot & Big Picture
Vistra Operations Company LLC is the operating subsidiary of Vistra Corp., one of the largest competitive power generators in the U.S. The company operates a diverse fleet of natural gas, nuclear, coal, and increasingly renewable generation assets, serving retail and wholesale electricity markets primarily in Texas (through TXU Energy) and across several other deregulated states. Its scale — nearly $18 billion in annual revenue — places it among the largest independent power producers in North America.
The financial story across the past nine years is one of dramatic swings. The early years (2017–2018) reflected a still-maturing business emerging from Dynegy's bankruptcy reorganization, with thin or negative margins. A period of decent profitability followed in 2019–2020, only to be crushed in 2021 by Winter Storm Uri and again in 2022 by adverse commodity and hedging outcomes. The rebound since 2023 has been sharp and sustained, fueled by higher power prices, improved hedging, the acquisition of Energy Harbor's nuclear assets, and surging demand from data centers and electrification trends.
| Fiscal Year | Revenue | EBITDA | Operating Margin | Net Margin |

Latest Quarter Snapshot
The most recent data — the quarter ending June 30, 2026, filed August 10, 2026 — is more current than the annual figures and offers the freshest read on operating momentum. Vistra generated $4.02 billion in revenue for the quarter, with EBITDA of $998 million. Operating margin came in at 13.8% and net margin at 7.6%, both healthy by historical standards for a power generator, though below the peak margins seen in full-year 2024.
| Metric | Q2 2026 (Period End June 30, 2026) |
|---|---|
| Revenue | $4.02B |
| EBITDA | $998M |
| Operating Margin | 13.8% |
| Net Margin | 7.6% |
| Current Ratio | 0.97x |
| Debt-to-Equity | 3.57x |
| Capital Expenditures | $883M |
| CapEx-to-Revenue | 21.8% |
The current ratio of 0.97x signals that short-term liabilities modestly exceed short-term assets — a pattern that has persisted over the past two years and warrants monitoring. Leverage remains elevated at 3.57x debt-to-equity.
Profitability
Vistra's profitability trend is striking in its volatility and recent recovery. Operating and net margins turned deeply negative in 2021 and 2022 as extraordinary weather events and commodity dislocations hammered earnings. The company then executed a powerful turnaround: operating margin climbed to 18% in 2023 and peaked at nearly 24% in 2024 — exceptional for a capital-intensive utility-adjacent business. Full-year 2025 shows some margin compression (operating margin pulled back to 10.7%, net margin to 5.3%), partly due to higher depreciation and interest costs tied to the Energy Harbor nuclear acquisition and ongoing capital investment. EBITDA of $3.89 billion in 2025 remains healthy in absolute terms, though down from the $5.92 billion peak in 2024. The Q2 2026 data suggests margins are stabilizing in the low-to-mid teens range. Gross margin data was not available in any of the 10-K filings reviewed.
Financial Health
Vistra's balance sheet has undergone a dramatic structural shift. Through 2021, the company carried virtually no net debt relative to equity (debt-to-equity ratios were at or near zero in 2020 and 2021). That changed materially with the 2023 acquisition of Energy Harbor and the associated financing: by year-end 2023, debt-to-equity had risen to 2.71x, and it continued climbing to 2.93x at end-2024 and 3.70x at end-2025. The most recent quarter shows the ratio at 3.57x. This is a meaningfully leveraged capital structure for a company whose earnings can swing sharply with power prices and weather — and it represents the single most important financial risk to monitor.
Liquidity, measured by the current ratio, has drifted below 1.0x in the most recent periods (0.96x at end-2024, 0.78x at end-2025, 0.97x in Q2 2026), meaning current liabilities exceed current assets. For a large power company with access to credit facilities this is not immediately alarming, but it does underscore that Vistra is running lean on short-term liquidity while funding heavy capital programs.
Capital Expenditures: Capex is rising substantially in both dollar terms and as a share of revenue — a hallmark of a business in aggressive growth and reinvestment mode. From $530 million (5.8% of revenue) in 2018, capex climbed to $1.26 billion in 2020, $1.68 billion in 2023, $2.08 billion in 2024, and $2.75 billion in full-year 2025 (15.5% of revenue). The Q2 2026 single-quarter capex of $883 million — representing 21.8% of that quarter's revenue — signals the investment pace is accelerating further into 2026. This reflects Vistra's significant buildout of new natural gas peaking capacity, nuclear uprates, battery storage, and solar projects to meet surging power demand. High capex intensity means free cash flow is materially lower than reported net income, and investors should account for this when assessing cash generation quality.
| Fiscal Year | Capital Expenditures | CapEx-to-Revenue |
|---|---|---|
| 2017 | $114M | 2.1% |
| 2018 | $530M | 5.8% |
| 2019 | $713M | 6.0% |
| 2020 | $1,259M | 11.0% |
| 2021 | $1,033M | 8.6% |
| 2022 | $1,301M | 9.5% |
| 2023 | $1,676M | 11.3% |
| 2024 | $2,078M | 12.1% |
| 2025 | $2,752M | 15.5% |
| Q2 2026 (single quarter) | $883M | 21.8% |
Growth
Vistra has delivered consistent top-line growth across measurable windows, driven by a combination of organic volume and price gains, retail customer growth, and transformative M&A (most notably Energy Harbor in 2023). The 10-year CAGR window is not available because SEC filing history for this entity does not extend back a full decade from the most recent fiscal year end — the earliest annual filing in the dataset begins with fiscal year 2017, which is insufficient to compute a reliable 10-year figure anchored at 2015.
| CAGR Window | Start Fiscal Year | End Fiscal Year | Start Revenue | End Revenue | CAGR |
|---|---|---|---|---|---|
| 3-Year | 2022 | 2025 | $13.73B | $17.74B | 8.9% |
| 5-Year | 2020 | 2025 | $11.44B | $17.74B | 9.2% |
| 10-Year | N/A | N/A | N/A | N/A | Not available — insufficient filing history |
Both the three- and five-year revenue CAGRs cluster tightly around 9%, suggesting that Vistra's top-line growth has been remarkably consistent once the severe loss years of 2021–2022 are included in the base. Given the acceleration in capital spending and strong power demand signals from AI data center buildouts and industrial electrification, management is clearly betting that this growth trajectory can be sustained or accelerated — though execution risk and commodity price exposure remain meaningful variables.
