Is CEG a good stock to buy? We came across a bullish thesis on Constellation Energy Corporation on Astute Optics – US’s Substack. The thesis was published on September 12th, when the stock was trading at $284.75, and CEG gained 3.87% since then. The gain appears to reflect optimism around long-term nuclear power agreements with Google and Amazon, strengthening revenue visibility as AI data centers drive electricity demand. In this article, we will summarize the bulls’ thesis on CEG. Constellation Energy Corporation’s share was trading at $295.79 as of October 13th 2026. CEG’s trailing and forward P/E were 27.83 and 20.66 respectively according to Yahoo Finance.
This isn’t the first time we see a power generation company pitched as a great investment. Power generation stocks have declined over the past year, with Vistra (VST) losing 23.00% amid softer Texas power prices and regulatory uncertainty, while NRG Energy (NRG) fell 37.44% amid disappointing earnings and higher financing costs following its LS Power acquisition. But does CEG’s recent recovery make this a good time to buy?

In July, we published an article about the 10 Best Pick and Shovel AI Stocks to Invest In and CEG ranked #2 in that article. CEG returned 23.63% since then. This article discusses Constellation Energy’s long-term nuclear power purchase agreement with Walmart. Before getting into our analysis, let’s take a look at the business and why some investors like the stock so much.
Constellation Energy Corporation (NASDAQ:CEG) generates and sells electricity, natural gas, and other energy products across the U.S., using a mix of nuclear, natural gas, geothermal, wind, solar, and hydroelectric power. Right now, its biggest growth opportunity is the rising demand for electricity from AI data centers, and this is the key thing to understand about the stock: massive data centers need constant, reliable power, and Constellation Energy Corporation’s nuclear plants can supply that without carbon emissions.

Over the past year, revenue grew 26% to $31.3 billion and earnings per share reached $10.23, though much of that growth came from the company’s January 2026 acquisition of Calpine rather than organic improvement. The stock trades at about 28 times trailing earnings, notably higher than the peer median of 21.1 times, showing that investors are paying a premium in the belief that the larger, combined company will deliver stronger earnings down the road. You can check out whether Constellation or Vistra is the better AI power stock to buy here.
The bullish argument centers on AI infrastructure: the idea that data centers will keep needing more dependable electricity, not less. Industry estimates cited in the report suggest data centers could drive over half of all power-demand growth through 2030, with U.S. data-center power needs potentially reaching 134.4 gigawatts by then, which would make scarce, always-on power sources like nuclear even more valuable. That trend is already playing out: Constellation Energy Corporation has locked in a 20-year power supply deal with Microsoft (NASDAQ:MSFT) tied to its Crane Clean Energy Center, the former Three Mile Island site.
Adding to that momentum, Constellation Energy Corporation secured a $1 billion federal loan to help restart a reactor at Three Mile Island, a sign of government backing for expanding nuclear power. The Calpine deal also added natural gas and geothermal plants to its portfolio, though it came at a cost of diluting shareholders, with the share count rising from 314 million to 360 million. If the larger, combined business can generate strong returns, there’s a long runway of growth ahead: the company already earns a healthy 15.1% return on equity and is guiding for 2026 earnings of $11.50 to $12.50 per share. Its power plants have also locked in strong future pricing, clearing a major capacity auction at $333, while the company plans to invest $3.9 billion in growth this year and has expanded its stock buyback program to $5 billion, both signs of management’s confidence in the business.
Wall Street mostly agrees with the bullish case, with the average analyst price target at $348.30, roughly 22% above the report’s reference price of $285.97, and estimates ranging as high as $441. However, that average target essentially assumes earnings will grow beyond what management itself has guided for this year, meaning the stock’s upside partly depends on either stronger-than-expected profits or investors being willing to pay an even higher premium for the shares. Adding a note of caution, the company’s most recent quarterly earnings actually fell 46.8% from a year earlier, so investors will want to watch whether growth from the larger, combined business shows up in the numbers soon.
That said, profitability and debt remain real concerns. The company’s margins run well below its peers, a sign that the business converts less of its revenue into actual profit than competitors do, and margins narrowed further in the most recent quarter compared to a year earlier. Cash generated from operations also declined by roughly a quarter in the latest quarter, and after accounting for the company’s heavy spending on power plants and infrastructure last year, free cash flow was a relatively modest $1.3 billion. The company also carries a sizable net debt load of about $24 billion, which limits financial flexibility. On top of this, risks around uranium supply tied to Russia, potential changes to a key federal nuclear tax credit, and the cost of protecting critical infrastructure from cyber threats all add uncertainty for a business that requires heavy ongoing investment.
Another risk for the stock is unplanned nuclear plant outages. Long-term power contracts provide revenue visibility but do not guarantee uninterrupted generation. Equipment failures or extended maintenance could leave Constellation producing less electricity than expected. Its nuclear fleet recorded 57 non-refueling outage days in 2025, up from 36 in 2024. Meeting contracted deliveries during outages could require buying replacement electricity at higher market prices. That could squeeze profi
