NEW YORK, July 1, 2026, 14:12 (EDT)
- Constellation Energy dropped roughly 5.8% by 1:56 p.m. EDT, sliding further than both utilities and the S&P 500 proxy.
- Citigroup lowered its target to $297 from $348 and kept a Neutral rating.
- The stock was down about 16% from the $279 Constellation paid in its June block buyback.
- A post-lockup block of as many as 5.12 million shares is roughly the same as all of CEG’s trading on Wednesday so far.
Shares of Constellation Energy Corporation NASDAQ:CEG slid sharply Wednesday. Still, bulls watching the power market saw PJM, the country’s top grid operator, preparing for what could be new highs in demand and prices as heat, air-conditioning use and data centers ramp up.
Shares fell 5.8% to $233.93 near 1:56 p.m. EDT. Volume came in at 5.23 million shares. The Utilities Select Sector SPDR Fund (NYSEARCA:XLU) slipped 1.3%. The SPDR S&P 500 ETF Trust (NYSEARCA:SPY) was little changed.

Citigroup Inc NYSE:C lowered its target on Constellation to $297 from $348 and kept a Neutral rating, MT Newswires reported, with the data showing up on MarketScreener. At 2:10 p.m. EDT, MarketScreener had CEG off 33.8% since Jan. 1.
The time factor stands out. Reuters said spot wholesale prices in some PJM regions spiked near $300 per megawatt hour early Wednesday, well above the usual $25 to $40 off-peak range. PJM was looking for prices to rise above $1,000 per MWh Wednesday evening near the Virginia data center area, and projected a 166.3-gigawatt demand peak for Thursday, topping its 2006 record.
Grid tightness tends to be the go-to bull case for big generators with flexible plants. Still, CEG shares on Wednesday seemed to move more on selling pressure than any sign of power shortage.
The June prospectus put a number on the overhang. Selling holders were set to offer 11 million shares at $281 each to the public. Constellation itself didn’t get any of the proceeds. Underwriters had a 30-day option to buy another 1.35 million shares. Constellation was also lined up to buy 2 million shares from the underwriters at the same $279 per-share price paid to the sellers.
| Supply marker | Filed amount | Read-through at $233.93 |
|---|---|---|
| June public offering price | $281.00 | CEG is trading 16.8% under that |
| Price paid to selling holders | $279.00 | CEG trades 16.2% lower than this price |
| Company block buyback | 2.0 million shares, about $558 million | Buyback price cleared the market |
| Post-June 30 eligible block | Up to 5,118,402 shares | That’s about 98% of this Wednesday’s volume |
| Eligible block vs shares outstanding | 5.12 million vs 357.10 million | About 1.4% of total shares |
The eligible block is the number that matters for investors. Once the June 30 lockup and the 30-day offering lockup expire, as many as 5,118,402 shares held by selling shareholders and not sold in the offering could hit the public market, along with director and officer shares—less than 1% of outstanding stock. The filing also said that actual sales, or just concern about sales, could drive down the stock price.
Constellation still has cash to fight the pressure. In a filing on June 2, the company said it picked up 2 million shares for around $558 million. After the deal, about $3.5 billion in buyback authority was left.
The stock is stuck with a near-term problem here. The long-run scarcity trade is still there, but on Wednesday the market saw near-term selling pressure. A 5.12 million-share block isn’t large compared to the company as a whole, but it’s almost a full day’s trading for this name, which is now breaking below the June secondary price.
Constellation’s asset story is still mostly about nuclear. Last week, President and CEO Joe Dominguez said Constellation’s four upstate New York nuclear plants “provide nearly half of the state’s clean power.” The company is pushing to renew the licenses for Ginna and Nine Mile Point Unit 1 through 2049.

Constellation’s June 30 sustainability report stuck to its message, linking long-term shareholder value to what it called “the nation’s largest portfolio of always-on, emissions-free generation assets.” The company also said its environmental management system applies to all Constellation-operated Nuclear and Power business units.

Pressure is hitting the power market now. Nikhil Kumar, program director at GridLab, told Reuters that “some coal plants in particular have efficiency issues” when temperatures spike. PJM said it had about 180.2 GW in generation capacity plus another 8 GW available from load-reduction, meeting the projected demand peak. Reuters
