TLDR
- CEG closed at $281.99, down 10.9% on the day, far worse than the S&P 500’s 1.51% drop
- Tech hyperscalers are reportedly pulling back from large power deals, hitting demand expectations
- A proposed federal rate cap in the PJM mid-Atlantic market could limit what CEG can charge for electricity
- A chemical leak at one of Constellation’s facilities sent workers to hospital, adding operational concerns
- Analysts still project Q1 EPS of $2.70, up 26% year-over-year, with full-year revenue expected at $38.71 billion
Constellation Energy (CEG) had a rough Thursday, dropping 10.9% to close at $281.99. That’s a steep fall, especially on a day when the broader market was already shaky.
Constellation Energy Corporation, CEG
The selling pressure came from multiple directions at once — and none of them were minor.
The biggest blow came from reports that large tech companies are walking back some of their power purchase commitments. These deals had been a cornerstone of CEG’s growth story, particularly its AI data center narrative.
Without that tailwind, investors started asking harder questions about how much the stock deserved to trade at a premium.
The selloff was then deepened by regulatory news. A proposed federal rate cap in the PJM mid-Atlantic power market — where Constellation operates a large chunk of its nuclear fleet — could put a ceiling on what the company charges for electricity.
That’s a direct hit to revenue potential, and the market priced it in fast.
Chemical Leak Adds to the Pressure
Then came the operational news. A chemical leak at one of Constellation’s facilities sent employees to the hospital, which added a layer of concern that went beyond the financial headlines.
It wasn’t catastrophic in scale, but the timing was bad. When confidence in a growth narrative is already wobbling, an incident like this doesn’t help.
All three pressures — demand uncertainty, regulatory risk, and operational issues — landed on the same day.
Analyst Estimates Still Hold
Despite the selloff, analyst projections for the company haven’t moved dramatically. Q1 EPS is still expected to come in at $2.70, which would be up 26% from the same quarter last year.
Full-year estimates call for earnings of $11.63 per share on revenue of $38.71 billion — a 51.6% revenue jump year-over-year if achieved.
The Zacks consensus EPS estimate has actually risen 2.41% over the past month, and CEG currently holds a Zacks Rank of #3, which is a Hold.
The forward P/E sits at 27.22 — above the industry average of 18.86 — meaning the stock was priced for growth before this week’s events.
The PEG ratio of 1.77 is below the Alternative Energy sector average of 2.0, which gives some cushion.
It’s also worth noting that even after Thursday’s drop, CEG was up 8.51% over the prior month — so the stock had been on a run heading into this.
Year-to-date performance now sits at -10.3%, reflecting just how sharp the reversal has been in 2026.
Investors will be watching the upcoming earnings disclosure closely to see whether the company addresses the power deal situation and provides any update on the facility incident.
