    Constellation Energy Q1 FY26 earnings call CEG

    May 11, 2026 Source

    Executive summary

    Constellation Energy Q1 FY26 — >20% base earnings growth through 2029, full-year guidance affirmed

    Constellation frames itself as a growth-with-optionality story: a highly visible base anchored by the inflation-geared nuclear PTC and long-term C&I contracts, layered with Calpine's gas/retail capabilities and multiple upside levers. The quarter was operationally clean and in line, and management leaned into disciplined capital return and rising free cash flow while awaiting PJM regulatory clarity it expects to firm up by year-end.

    Highlights

    5
    • Q1 GAAP EPS of $4.49 and adjusted operating (non-GAAP) EPS of $2.74, up $0.60 vs Q1 FY25, driven mostly by ~$2/share of full-year Calpine accretion plus higher PJM capacity prices

    • Affirmed full-year 2026 adjusted operating EPS guidance of $11-$12 per share

    • Repurchased ~1.2 million shares at ~$285 average for $335 million under the increased $5B authorization

    • Placed two new generation projects in service post-Calpine: 105 MW Pastoria solar (CA) and the 460 MW Penn Oak Creek gas peaking facility (TX)

    • Strong nuclear operations — 40 million MWh generated at a 92.3% capacity factor; CCGT/cogen fleet forced outage factor of just 5.1%

    Concerns

    4
    • More planned nuclear refueling outage days vs Q1 FY25, lower ZEC pricing across state programs, and higher cost to serve load from winter storm Fern partially offset the quarter's gains

    • Some hyperscaler customers paused contract negotiations awaiting PJM regulatory clarity

    • ERCOT forward power prices weak in the 2028-2029+ period despite a large data-center pipeline; management calls the outer years undervalued

    • Crane full capacity credit and nuclear uprate EPS accretion both remain gated on FERC/interconnection approvals (uprates not accretive until 2030 at earliest)

    Segment performance

    2
    SegmentRevenueYoYQoQMargin
    Nuclear fleet (operated plants)
    Firm, emissions-free generation of 40 million MWh; the 92.3% capacity factor (captured in subsector KPIs) reflected more planned refueling outage days than typical for a first quarter. The nuclear fleet is the primary cash and base-earnings engine, geared to the inflation-growing PTC.
    Nuclear generation output: 40 million MWh (Q1 FY26)
    Combined cycle & cogeneration (thermal) fleet
    Generated 23 million MWh at a 47.1% capacity factor; unlike the base-load nuclear fleet, the thermal fleet is dispatch-driven and varies with weather and system conditions. The 5.1% forced outage factor (in subsector KPIs) means units delivered when called nearly 95% of the time — management positions this reliability as a differentiator as large loads come online.

    Risks & headwinds

    8
    PJM regulatory uncertainty delaying large-load contractingresolution expected — proposal to FERC in June; management expects clarity by year-end 2026

    some hyperscaler customers paused contract negotiations awaiting clarity (unquantified)

    Mitigation: Engaging PJM on the backstop and colocation framework; diverse project set (~5,000 MW queued) aligned with the proposed framework; some customers proceeding now regardless.

    ERCOT forward power-price weakness2028-2029 and beyond

    forwards beyond 2029 appear to price only ~10,000-15,000 MW of load vs a large potential pipeline; near-term weakness

    Mitigation: Company well hedged and protected in the short term; views outer-year prices as undervalued and expects upward pressure as load materializes.

    Higher cost to serve from winter storm FernQ1 FY26

    incremental ancillary charges from grid operator calling on operating reserves (unquantified $)

    Mitigation: Business performed well operationally through the storm; a one-time event partially offsetting the quarter.

    Lower ZEC pricing across state programsQ1 FY26 / ongoing

    unquantified negative to Q1 earnings

    Mitigation: Offset by nuclear PTC construct which grows base earnings with inflation.

    More planned nuclear refueling outage daysQ1 FY26

    reduced Q1 nuclear capacity factor to 92.3%; more outage days than typical for Q1

    Mitigation: Timing of planned outages; strong overall nuclear operations.

    FERC/interconnection approval risk on Crane and nuclear upratesFERC response expected June/July 2026; uprates 2030+

    Crane full capacity credit and uprate EPS accretion gated on approvals (uprates not accretive until 2030 earliest)

    Mitigation: CIR transfer filing submitted; working with utilities to shorten interconnection timelines; PJM acknowledged importance of the waiver.

    PJM market-design / colocation rule uncertainty (Option B legal questions)ongoing; management wants colocation date moved up

    unquantified; colocation implementation date indicated as 2029

    Mitigation: Active engagement; support for energy/reserve market co-optimization; monitoring legal risk around discriminatory reliability treatment of loads.

    Concentration on hyperscaler/data-center large-load customersongoing

    unquantified; growth upside tied to a small set of hyperscaler counterparties

    Mitigation: Diverse solution set (backup generation, curtailability, demand response, retail); customers can shift workloads across regions to manage curtailment.

    Q&A highlights

    8

    Why are ERCOT forwards weak despite strong data-center pipeline activity, and how does the market evolve?

    Joe called it a timing issue — the load isn't on the system yet and interconnection timing is uncertain; he views ERCOT as undervalued, especially outer years. An executive specified focus on 2028-2029+: with >400,000 MW of large loads in queue but the forward market beyond '29 apparently pricing only 10,000-15,000 MW, realized load near 30,000 MW would push prices up; near-term weakness is unsurprising and they are well hedged.

    the forward market beyond '29 to us, appears like something that's only expecting 10,000 to 15,000 megs. So if we see numbers like 30,000 megs, we believe that the market will see upward pressure

    Detailed Narrative

    01

    Long-term outlook and upside levers

    Management reiterated a base EPS growth rate exceeding 20% through 2029, anchored by the nuclear PTC (which grows with inflation), long-term contracts with high-quality counterparties, and durable customer margins from the nation's largest C&I retail platform. They also expressed conviction in a rolling 10%+ long-term base EPS growth rate. The outlook is described as arguably conservative through 2029, with quantified upside levers on Page 13: additional long-term data-center offtakes at nuclear and gas plants, higher gas fleet utilization from around-the-clock demand, positive gearing to >2% inflation via the nuclear PTC, and higher returns on growing free cash flow.

    02

    Free cash flow trajectory

    Constellation expects $8.4 billion of free cash flow before growth across 2026-2027 and, newly disclosed this call, $11.5-$13 billion across 2028-2029 — roughly a 45% increase at the midpoint. Management acknowledged it could have communicated the FCF outlook better at the March business update and provided updated figures on Page 13. On cash conversion, CFO Shane Smith said the EBITDA-to-FCF relationship should not change materially from history given most cash comes from the nuclear fleet, and that upside from the identified levers largely drops to the bottom line as it does not require incremental investment.

    03

    PJM regulatory landscape

    PJM issued a white paper ("Powering Reliability Through Market Design") and a market-based solution for incremental capacity needs driven by large-load growth, with a proposed timeline to vote and submit to FERC in June — faster than Constellation had hoped. Management wants the same speed applied to the colocation document and wants the colocation implementation date (indicated as 2029) moved up. General Counsel David Dardis welcomed co-optimizing energy and reserve markets and reducing reliance on capacity markets, but flagged real legal questions around Option B's differential/discriminatory reliability treatment of loads. Joe expects clarity on these issues by year-end.

    04

    Data-center demand and contracting

    Hyperscaler demand for compute and power has not slowed — projected 2026 spending is nearly 75% higher than last year and still being revised up. Constellation submitted ~5,000 MW of new capacity resources (nuclear uprates, new gas, battery storage) into PJM's interconnection queue. Contracting cadence varies: some customers advance deals now while others pause for regulatory clarity. Management drew a parallel to ERCOT after Texas Senate Bill 6, where transactions resumed once colocation requirements were established, and expects the same in PJM. It declined to name a fixed new-to-existing capacity ratio, expecting a broad mix of curtailment, backup generation, and demand-response solutions.

    05

    Generation development execution

    Post-Calpine, Constellation placed two projects into service this quarter: the 105 MW Pastoria solar project (adjacent to a >750 MW combined-cycle plant, part of a combined solar-and-storage project supporting the California Department of Water Resources' 2035 carbon-neutrality goal) and the 460 MW Penn Oak Creek natural gas peaking facility in Texas, designed for rapid startup and grid reliability. Management highlighted that Calpine's development and commercial capabilities supplement Constellation's fleet, enabling gas, solar, storage, and data-center transactions.

    06

    ERCOT market view and Texas powered-land deals

    On ERCOT, management called recent forward-price weakness a timing issue and the outer years undervalued. An executive noted over 400,000 MW of large loads in the queue; while not expecting anywhere near that, they see the forward market beyond 2029 pricing in only ~10,000-15,000 MW — so 30,000 MW of realized load would create upward price pressure. Constellation has three data-center projects in Texas where customers meet reliability commitments via firm backup generation or full curtailability during grid stress; these gas-adjacent powered-land deals command premium rates and allow full grid access so customers can pair them with firm carbon-free nuclear energy. Last week the company received PUCT approval of the net-metering agreement for the CyrusOne powered-land deal at Freestone Energy Center.
