Constellation Energy raises EPS outlook to $12 on strong nuclear performance and 920 MW of new clean power PPA deals.
Constellation Energy delivered a strong second quarter that prompted management to elevate its full-year 2026 adjusted operating earnings guidance to $11.50–$12.50 per share, with the midpoint of $12.00 now matching the previous upper bound. The company reported adjusted operating earnings of $2.55 per share for Q2, up $0.64 year-over-year, driven by accretion from the Calpine acquisition, firmer PJM capacity prices, and robust commercial execution.
"Strong results, an increase in guidance, positive regulatory developments, good progress on strategic transactions," said Chairman, President and CEO Joe Dominguez. "Our team delivered."
GAAP earnings reached $1.42 per share in the quarter, partially offset by a $115 million negative swing in Illinois ZEC revenue recognition—$85 million recognized in Q2 2026 versus $200 million in Q2 2025—though this timing item had no impact on full-year guidance. The raise at mid-year reflects confidence that management may revisit the outlook again following the third-quarter earnings call after the summer peak demand period.
The nuclear fleet demonstrated operational excellence amid a heavy refueling schedule, maintaining a 93% capacity factor and generating 40 TWh of carbon-free electricity despite six planned outages averaging 23 days. A major turbine upgrade at Byron Unit 1 was completed during this period, and the fleet's average outage duration beat the industry average by 40 percent. CFO Shane Smith highlighted the "consistency, discipline, and expertise" of the nuclear operations team, a capability that Dominguez linked to the company's safety culture and community trust.
The most significant commercial development was the signing of approximately 920 megawatts of long-term nuclear power purchase agreements with an average duration of 18.5 years. Counterparties are investment-grade customers, and the deals reflect the company's conviction about long-term value for the nuclear fleet. While Constellation declined to disclose specific pricing or customer identities beyond what customers publicly reveal, Walmart's first-ever nuclear PPA stood out as a landmark transaction—the first such agreement for a major retailer.
"Walmart is helping to define how corporate customers think about nuclear energy, reflecting a growing recognition that achieving ambitious decarbonization goals requires access to around-the-clock carbon-free generation," Dominguez said. "This transaction is only the beginning of a wonderful partnership with this iconic American company."
These agreements bring roughly 30 percent of Constellation's clean baseload output under long-term contract, positioning the nuclear fleet as a premium product for hyperscalers and large corporates requiring 24/7 clean power.
Regulatory clarity has begun to accelerate deal flow. Dominguez, who had cautioned in March that contracting was lagging due to regulatory uncertainty, struck a notably more optimistic tone on PJM and FERC progress. "The worst thing for deal execution is ambiguity and uncertainty," he said. "I believe that once we do get clarity, we're going to see here in PJM what we've seen in many places where deal flow will kick off with a bit of a bang."
Key developments include FERC's order requiring every regional transmission operator to justify how existing tariffs serve large loads, PJM's reliability backstop procurement target of 6.8 GW, and the launch of a bilateral matchmaking process for interconnection. Constellation expects clarity on co-location rules by Q1–Q2 2027 after PJM files its response around November 2026.
On the capital front, Constellation has deployed approximately $2.2 billion in share repurchases year to date, with $2.8 billion remaining under authorization. CFO Smith revised the 2029 capital allocation sensitivity to include a floor of $0.20 per share from completed purchases and upside beyond $0.75 per share.
The Crane Clean Energy Center restart achieved critical regulatory milestones: the Nuclear Regulatory Commission approved the new fuel licensing amendment, and the Federal Energy Regulatory Commission granted a waiver to transfer capacity injection rights from the retiring Eddystone facility, clearing an initial deliverability hurdle. The plant remains on track for a second-half 2027 return. Constellation also filed subsequent license renewal applications for Ginna and Nine Mile Point 1 in New York.
Separately, the agreement to sell the Brazos Valley Energy Center to LS Power for $860 million—approximately $1,420 per kilowatt—will satisfy the final Department of Justice divestiture requirement linked to the Calpine acquisition. "The fact that smart private equity buyers with long track records in competitive power markets are willing to pay over $1,400 a kW for Texas assets in a soft ERCOT market should tell you everything you need to know about the value of the efficient gas fleet that we now own," Dominguez said.
The nuclear production tax credit received a modest but meaningful boost: the Internal Revenue Service's 2025 inflation adjustment lifts the projected 2030 PTC strike price from $49.88 to $50.88 per megawatt-hour, adding approximately $0.30 per share to 2030 base earnings. Combined with the growing long-term contract backlog and remaining buyback optionality, this foundation supports management's confidence in sustaining double-digit base earnings growth into the 2030s.
