Which utility stock is the better choice for your long-term portfolio?
Investors are increasingly looking to the power grid for growth as technology and green energy converge. Deciding between Constellation Energy (NASDAQ:CEG) and NextEra Energy (NYSE:NEE) depends on your preferred flavor of energy production.
Constellation Energy stands out as a pure-play leader in nuclear power, increasingly focused on providing carbon-free electricity to power-hungry data centers. NextEra Energy balances a massive regulated utility business in Florida with a world-class renewable energy development arm. Both companies offer different paths to benefit from the growing electrification of the modern economy.
Constellation Energy generates electricity from various sources including natural gas and hydro, but its crown jewel is the largest nuclear fleet in the nation. The company recently strengthened its position by acquiring Calpine, a move that bolstered its reach among commercial and industrial customers. It currently serves roughly 80% of the Fortune 100, including high-profile tech giants like Microsoft.
In its 2025 fiscal year (FY), revenue reached $25.5 billion, which represented growth of 8.3% over the previous year. The company reported net income of $2.3 billion for the same period. This resulted in a net margin of 9.1%, a decrease from the 15.9% net margin recorded in the prior year.
As of its December 2025 balance sheet, the debt-to-equity ratio was 0.6x. This ratio compares total debt to shareholder equity to show how much a company relies on borrowed money. The current ratio, which measures the ability to pay short-term debts with current assets, was 1.5x. Free cash flow, which is cash from operations minus capital expenditures, totaled $1.3 billion for the year.
NextEra Energy operates through two primary segments, including Florida Power & Light and NextEra Energy Resources. Florida Power & Light is the largest electric utility in Florida, serving more than 6 million customer accounts through long-term franchise agreements. The company is a massive player among electric utility stocks and leads the world in wind and solar generation.
In FY 2025, revenue reached $27.4 billion, an 11% increase compared to the previous year. The company delivered net income of $6.8 billion for the fiscal period. This performance translated to a strong net margin of 24.9%, highlighting the profitability of its regulated and contracted energy businesses.
As of its December 2025 balance sheet, the debt-to-equity ratio was 1.8x. This level of debt is higher than its peer, though common in capital-intensive utility businesses. The current ratio stood at 0.6x, and the company generated free cash flow of $3.2 billion during the year.
Constellation Energy faces significant regulatory and legislative risks, particularly regarding federal market designs and nuclear licensing requirements. Changes in policies like the nuclear production tax credit could impact its financial results. The company also manages operational risks inherent in the nation’s largest nuclear fleet, including radioactive waste storage and potential decommissioning liabilities.
NextEra Energy is highly sensitive to regulatory shifts at both state and federal levels, which can impact its ability to recover costs. The company recently faced challenges related to a proposed acquisition involving Dominion Energy. Additionally, its heavy presence in Florida makes it vulnerable to extreme weather events like hurricanes, which can cause significant property damage.
While NextEra Energy appears to offer a lower multiple on Forward P/E relative to future earnings estimates, Constellation Energy carries a much lower P/S ratio.
| Metric | Constellation Energy | NextEra Energy |
|---|---|---|
| Forward P/E | 22.8x | 20.8x |
| P/S ratio | 3.8x | 6.4x |

The rise of artificial intelligence has led to unprecedented demand for electricity to power the army of computers required for AI. This tailwind makes Constellation Energy and NextEra Energy attractive stocks to own. I would buy both, but picking just one comes down to which is a better fit for your investment goals.
NextEra Energy is the better choice for conservative and income-focused investors. It pays a robust dividend yielding over 3% as of Aug. 31, and its low beta of 0.65 means the stock is not volatile. Its regulated utility business in Florida provides income stability, while its NextEra Energy Resources division is growing as it provides power to data centers. As a result, revenue in the second quarter of 2026 reached $7.5 billion, up from $6.7 billion in the prior year.
Constellation Energy offers a much lower dividend yield of 0.62% and its beta of 1.1 indicates elevated share price volatility. The stock hit a 52-week low of $228.63 on July 1 as its earnings guidance missed Wall Street expectations.
However, the company is seeing strong revenue growth. Q2 sales hit $7.5 billion, up from $6.1 billion and it raised its full-year adjusted (non-GAAP) operating earnings guidance range, although not as high as Wall Street would have liked. Constellation is for investors who want to take advantage of the share price dip and who have a high risk tolerance.
