Key Highlights

  • Constellation agreed on Sept. 10 to buy the 609-MW Rhode Island State Energy Center from Shell for $715 million, or about $580 million net of expected first-year tax benefits.
  • The company expects the deal to be immediately accretive, to beat its 10% unlevered return threshold and to leave its $5 billion buyback plan through 2027 intact.
  • CEG raised 2026 adjusted operating EPS guidance to $11.50-$12.50 on Aug. 6, yet shares fell about 13% from Sept. 9 to Sept. 18 amid Calpine-related selling.
  • CEG shares closed at $263.46 on Sept. 22, down about 25% year to date, with a mean analyst price target of about $349 among the 20 analysts tracked.

Constellation Energy Corporation (NASDAQ:CEG) agreed on Sept. 10 to buy the Rhode Island State Energy Center from a Shell (NYSE:SHEL) Subsidiary for $715 million. The deal is a modest but pointed bet on dispatchable Natural Gas generation in New England. The company says the 609-megawatt plant will be immediately accretive to operating earnings, will earn returns above its 10% unlevered hurdle, and will not affect its plan to complete $5 billion of authorized share Buybacks by the end of 2027.

For shareholders, the deal matters less for its size than for what it signals. Constellation is using its Balance Sheet to add reliable power where its retail customer Business is growing, even as it divests other plants to meet regulatory conditions from its Calpine acquisition. The deal has done little for the stock so far. CEG shares fell about 13% between Sept. 9 and Sept. 18, a slide tied to Calpine-related share sales and sector-wide pressure rather than to the Acquisition itself. The stock closed at $263.46 on Sept. 22.

Inside the RISEC Deal

Under the Sept. 10 agreement, Constellation will acquire 100% of RISEC Holdings, LLC from Shell Energy North America (US), L.P., a subsidiary of Shell plc, for $715 million, subject to customary purchase-price adjustments. The company said the price equals about $580 million net of expected first-year tax benefits.

The Rhode Island State Energy Center, in Johnston, R.I., is a natural gas-fired combined-cycle plant with two combustion turbines and one steam turbine. It has served the New England grid since 2002 and sells electricity and capacity into the competitive ISO New England wholesale market. It will join Constellation's merchant generation portfolio. Based on the headline price, Constellation is paying roughly $1,170 per kilowatt of capacity, or about $950 per kilowatt net of the expected tax benefits.

"RISEC checks all of these boxes and will be immediately accretive to Constellation's business plan," Chairman and CEO Joe Dominguez said, citing the plant's position on both the electric grid and the natural gas pipeline system. Closing requires customary regulatory approvals. The transaction is expected to close in the first quarter of 2027. Until then, RISEC will continue to operate under Shell's ownership.

Recycling Capital After Calpine

The Rhode Island purchase comes weeks after Constellation agreed in August to sell the Brazos Valley Energy Center, a 606-megawatt gas plant in Texas's ERCOT market, to LS Power for $860 million before closing adjustments. The company said that sale is the last divestiture required under its regulatory commitments for the Calpine acquisition, which closed in January 2026. It expects the Brazos Valley sale to close by year-end, subject to Department of Justice approval.

Taken together, the two transactions swap a Texas plant for a similar-sized New England asset at a lower headline price. They also concentrate capacity in a region where Constellation says its customer business is growing. Constellation describes itself as the largest U.S. nuclear operator, with about 55 gigawatts of total capacity, so the Rhode Island plant adds only around 1% to its fleet. Management has framed the plant as a reliable, well-located asset to support its expanding New England customer base.

Second-Quarter Results and Raised Guidance

In its Aug. 6 release, Constellation reported second-quarter GAAP Net Income of $1.42 per share, down from $2.67 a year earlier, largely because of unrealized fair-value losses and Calpine-related items. Adjusted operating Earnings rose to $2.55 per share from $1.91, which the company attributed mainly to the addition of Calpine and favorable market conditions, partly offset by nuclear outages. The adjusted figure beat a $2.33 consensus.

Constellation raised its full-year 2026 adjusted operating earnings guidance to $11.50 to $12.50 per share. It also signed about 920 megawatts of new long-term nuclear power purchase agreements with investment-grade customers, running 15 to 20 years and starting between 2029 and 2032. Those include a 176-megawatt deal with Walmart (NYSE:WMT). The nuclear fleet produced 44,160 gigawatt-hours in the quarter and ran at a 93.0% capacity factor, excluding Salem and South Texas Project.

Regulatory progress continued at the Crane Clean Energy Center, the former Three Mile Island Unit 1. FERC approved a Waiver to transfer interconnection rights to the plant, and the NRC approved its fuel license amendment, keeping a 2027 restart on track, the company said. More recently, on Sept. 21, Constellation and Toyota Motor North America (NYSE:TM) announced a 15-year renewable energy agreement supporting new solar generation developed by Ferrovial (NASDAQ:FER).

Why the Stock Has Lagged

Despite the stronger outlook, CEG shares are down about 25% year to date and well below their October 2025 closing high near $404. The latest drop has been linked to shares issued as Calpine deal consideration reaching the market, as well as rising bond yields that pressured nuclear and Utility stocks. Institutional holder Reaves Asset Management described the selling as "a transfer of shares from a motivated seller to long term holders." Among the 20 analysts tracked with price targets, the mean target is $349.

Risks to the Thesis

  • Merchant exposure: RISEC sells into a competitive wholesale market, so its earnings depend on New England power and capacity prices, as well as natural gas costs.
  • Regulatory timing: Both the Rhode Island purchase and the Brazos Valley sale require approvals, and delays could shift the expected financial benefits.
  • Share overhang: Continued sales of Calpine consideration shares could keep pressure on the stock regardless of operating results.
  • Nuclear operations and policy: Outages, the Crane restart schedule and federal energy policy remain key swing factors for a company whose fleet is dominated by nuclear power.

Milestones Ahead for the RISEC Deal

Investors will watch for regulatory filings and approvals tied to RISEC, and for the Brazos Valley sale to close by year-end. Constellation's third-quarter results, which the company has historically reported in early November, should show whether it is tracking toward its $11.50 to $12.50 guidance. They should also bring updates on new data-center power agreements and on the Crane restart. The pace of share repurchases under the $5 billion authorization will also be closely followed.
