CEG · Q4 2025 Earnings

Constellation Energy

Reported February 24, 2026

30-second summary

Constellation closed FY2025 with $9.39 non-GAAP EPS — dead-center of the narrowed $9.05–$9.45 guide — and initiated FY2026 at $11–$12, implying ~17–28% YoY growth. The bigger signal is qualitative: management introduced a 20% base-earnings CAGR target through 2029 (base EPS growing from $6.65 in 2026 to $11.40–$11.90 in 2029, a subset of total adjusted operating EPS), reframed PJM regulatory uncertainty as non-blocking ("Constellation constructs deals now…regardless of how the PJM proceedings resolve"), and described Calpine integration as ahead of schedule. Tone shifted from "awaiting clarity" to "executing through it."

Management tone

Q2 commercial positioning (late-inning deal, 20-year PPAs) → Q3 execution patience (deal slips, "not rushing" Calpine sales) → Q4 decisive posture and multi-year framing.

The most material shift is on regulatory dependency. For three quarters, the unannounced data center deal has been gated by external timing — utility interconnection, customer approvals, PJM proceedings. This quarter, Dominguez explicitly cut the chain: "Regardless of how the PJM proceedings resolve, Constellation constructs deals now to power America's growth in AI with our firm and clean nuclear power." Coupled with the acknowledgment that the executive order had required Constellation to "rethink and renegotiate" PPA terms, this is management choosing to absorb regulatory risk rather than wait it out. The posture shift is meaningful because last quarter the deal narrative was already on its second "hope to close" iteration.

The framing of data center demand has also escalated. In Q2 it was the differentiated product (nuclear-adjacent land, 20-year fixed PPAs); in Q3 it was a structural backdrop ($0.75T capex cycle). This quarter Dominguez said "the growth we're seeing is like nothing we've seen before" and paired the superlative with a hard data point — replacement firm-power costs at ~$3,000/kW versus historical $2,500. Demand is now framed as the foundational thesis, with the new 20% base-earnings CAGR-through-2029 target operationalizing that conviction into a number — applied to base EPS, not total EPS.

Calpine framing has compressed from acquisition (Q2) to "not rushing" divestitures (Q3) to "integration is progressing as planned…teams are energizing, and we're ahead of schedule" (Q4). The "ahead of schedule" language is the new piece — Q3 reframed the timeline as a choice, Q4 claims it's beating the choice.

A subtler shift is in the megawatt-addition vocabulary. Q2 distinguished nuclear (the product) from gas (a separate fleet). Q4 explicitly bundles them: "pairing our nuclear power with Constellation's ability to bring incremental capacity through batteries, demand response, upgrades, and gas-fired generation." This is the first quarter where the combined platform is described as a single commercial offering rather than two assets under one roof.

What did not change: management still declined to disclose new-nuclear cost per kW, still framed Westinghouse partnership progress qualitatively without quantitative commitments, and the unannounced data center deal still has no counterparty named on the print.

Recurring themes management leaned on this quarter:

Data center AI demand durability and growth accelerationNuclear fleet as unmatched competitive moat with 147M MWh still availableCalpine integration driving coast-to-coast scale and operational excellenceRegulatory flexibility and customer-specific solutions over one-size-fits-all approachBalance sheet strength enabling M&A, organic growth capex, and aggressive buybacksBase EPS growth 20% CAGR through 2029 with significant embedded optionality

Risks management surfaced:

Data center demand durability questioned despite momentum (acknowledged bumps from DeepSeek, talent, executive order)PJM regulatory proceedings outcome uncertainty and potential delays to interconnection (e.g., Crane to 2030s)Higher inflation creating depreciation headwinds from Calpine purchase accounting fair value marksReplacement megawatt costs rising (now ~$3,000/kW from historical $2,500) pressuring competitiveness for new buildsPotential competitive new supply entering market via utility self-build initiatives (noted as lower risk)

Answers to last quarter's watch list

The high-end EPS cut signal — FY2025 actual EPS of $9.39 landed in the upper half of the $9.05–$9.45 range, $0.14 above the $9.25 midpoint. The Q3 ceiling cut from $9.60 looks conservative in retrospect rather than a real expectation reset. Status: Resolved positively

Data center deal announcement before the Q4 call — No counterparty, MW size, or pricing for the unannounced "late-inning" deal was disclosed on the print. Management's framing has pivoted from a specific deal closing to a broader "constructs deals now…multiple structures" narrative, and Dominguez acknowledged the executive order required Constellation to "rethink and renegotiate some of the terms of the PPAs." This is the third consecutive quarter without an announcement of that specific deal, though the print did include a new 380 MW CyrusOne agreement at Freestone (plus an exclusive on a 380 MW Phase 2). Status: Resolved negatively

Calpine closing or first integrated guidance — The transaction has closed, total generating capacity is now 55 GW, and FY2026 EPS guidance of $11–$12 is the first integrated guide combining gas and nuclear. Management said integration is "ahead of schedule." No divestiture asset list or sale prices were disclosed on the print, though Shane referenced required divestitures of "York 2 and Jack Fusco stations" assumed to close in Q3. Status: Resolved positively

Nuclear capacity factor at 96.8% — does it sustain? Q4 ex-Salem/STP capacity factor came in at 93.1%, down 370bps from Q3's fleet-ceiling reading and below the 95% threshold flagged last quarter. This is within the fleet's normal historical range but does not sustain the Q3 outperformance — the operating leverage from sustained 96%+ availability was not extended into Q4. Status: Resolved negatively

Outer-year power price evidence in PPAs — No specific PPA price points were disclosed. Management did anchor the broader pricing argument with a new data point — replacement firm-power cost now ~$3,000/kW versus historical $2,500 — which supports the directional claim but is not contract-specific. Status: Continue monitoring

Westinghouse partnership milestones — No specific cost-per-kW disclosure or formal new-nuclear capital commitment. The new-nuclear capex framework remains undisclosed. Status: Continue monitoring

What to watch into next quarter

The 20% base-earnings CAGR through 2029 — first-year delivery. The CAGR runs off base EPS ($6.65 in 2026 → $11.40–$11.90 in 2029), not total adjusted EPS. Watch base-EPS trajectory disclosed in interim updates against the $6.65 → $7.98 (+20%) one-year step. The $11–$12 total EPS guide is a separate yardstick; the credibility of the multi-year story specifically depends on base-EPS progression, since enhanced earnings (~40% of 2026 total) are explicitly variable.

A named data center deal counterparty by Q1. Dominguez has shifted from "this year" to "deals now regardless of PJM" — a deliberate decoupling. The credibility of that decoupling requires at least one disclosed counterparty, MW size, and tenor for the long-awaited hyperscaler transaction on the next print. Another "executing multiple structures" framing without a name would mark four quarters of unfulfilled commercial narrative.

Calpine divestiture disclosure. Integration is now "ahead of schedule" and York 2 and Jack Fusco are flagged for Q3 close. Watch for specific sale prices and net-proceeds use, and whether the Q3-close assumption holds.

Nuclear capacity factor reversion. Q4's 93.1% is back in normal range after Q3's 96.8%. Watch whether FY2026 fleet-average sustains above the FY2025 level or signals that Q3 was the cycle peak. The 24-month refueling cycle transition disclosed this quarter is a structural lever but won't show in operating data for several years.

New-nuclear cost disclosure. Multiple quarters of qualitative-only framing with no quantitative anchor. A specific cost-per-kW figure or any uprate program economics would be a step-change disclosure; continued qualitative-only framing is itself a tell.

FCF realization vs the $2B+ incremental target. FY2025 FCF of $1.29B is the baseline. Watch whether Q1/Q2 FY2026 cash conversion tracks toward an incremental $2B+ run rate, or whether Calpine purchase-accounting depreciation continues to compress GAAP-to-cash gaps.
