- Constellation Energy posts Q1 numbers Monday. Investors zero in on data-center power demand, progress with the Calpine integration, and the timeline for restarting nuclear operations.
- The stock ended Friday at $303.63, marking a second straight day of declines before the earnings release.
- Investopedia figures show options pricing is signaling about a 7% swing after earnings.
Constellation Energy faces Monday’s earnings with the stock still lagging and shareholders waiting to see if its AI-fueled power strategy can translate into real profits instead of just hype. The company plans to release first-quarter 2026 results at 10 a.m. EDT on May 11.
Timing played a role here. Shares of Constellation slipped to $303.63 by Friday, down from $322.78 on Wednesday, according to company market data, as traders trimmed exposure ahead of the report. The nuclear-power trade also lost some steam.
Options traders are pricing in a roughly 7% swing for Constellation shares by the end of next week, according to Investopedia. The estimate, based on options contracts tied to the stock, comes ahead of the company’s results. Visible Alpha figures quoted by Investopedia peg first-quarter adjusted earnings at $2.34 per share, with revenue forecast at $8.66 billion.
It’s also shaping up as an early big test since Constellation wrapped up its Calpine buyout in January—a move the company claims made it the top electricity producer in the U.S. Together, they’re now running about 55 gigawatts of capacity, with Calpine’s natural gas and geothermal assets joining Constellation’s nuclear portfolio.
The company says it’s targeting adjusted operating earnings of $11 to $12 a share for 2026. Growth capital spending is set at $3.9 billion, and there’s a $5 billion buyback in play. Adjusted operating earnings exclude certain items management doesn’t count as core.
Bulls still point to demand from heavyweights with big data centers, particularly those focused on cloud or AI. Microsoft, Meta, and other tech firms keep pushing for nuclear and other reliable power, as their sprawling server hubs tax local grids and make hitting climate goals tricky.
But when it comes to timing, that’s the sticking point. Last month, UBS analyst William Appicelli dropped his price target on Constellation to $388 from $420, keeping his Buy call. He pointed to overhangs like uncertainty around PJM, FERC rule clarity, and looming share lockup expiries. PJM covers much of the Mid-Atlantic and Midwest as grid operator; FERC is the federal regulator.
The restart of the old Three Mile Island reactor—now rebranded as the Crane Clean Energy Center—stands out as a key test, especially with plans to supply Microsoft’s data centers. PJM flagged the possibility of the grid connection slipping to 2031. Still, Chief Executive Joseph Dominguez told investors, “We are working on that with PJM, and we continue to expect to start this unit in 2027.” Melius Research analyst James West put it bluntly to Reuters: “We continue to see PJM clarity as the unlock.” Reuters
Signals from rivals are all over the map. Vistra posted a quarterly profit this week, reversing last year’s loss as power demand and prices climbed. At the same time, Reuters reports U.S. power firms are jacking up rates and boosting capital outlays to handle the load from AI-powered data centers.
NRG Energy fell short of quarterly profit expectations as mild Texas weather and rising costs weighed on results. Still, executives highlighted a pipeline of generation-upgrade projects across their current fleet. The takeaway: demand remains robust, but there’s no escaping the impact of weather, cost of fuel, financing, and execution.
Exelon bumped up its capital-spending outlook this week, pointing to utilities boosting budgets while tech firms ramp up data center construction. That means Constellation stays right in the thick of things—demand is strong, but it’s hardly a calm market. More grid spending can fuel growth, but it’s also sparking new debates about cost burdens.
On Monday, the focus lands on Calpine’s numbers, plant outages, hedging, cash flow, buybacks, and how quickly those long-term power deals are stacking up. If management sticks to the 2026 outlook as-is, that could help the stock find its footing. But if there’s a holdup on grid approvals or softer talk around new contracts, investors might hold off.
