PJM clarity finally unlocks Constellation's 920 MW of nuclear deals — and the stock hasn't budged
Q2 guide raised to $11.50–12.50 as Walmart signs its first nuclear PPA; the tape is still digesting ERCOT risk

The quarter that turned 'behind timeline' into 920 MW
Constellation Energy's Q2 2026 report is the payoff of a bet management placed back in March, when Joe Dominguez admitted contracting had stalled behind a new wave of regulatory uncertainty. Three months later, the company has signed roughly 920 MW of long-term nuclear power purchase agreements, raised full-year guidance by $0.50, and — perhaps most tellingly — brokered Walmart's first-ever nuclear offtake. On the 2026-03-31 call, Dominguez described deal conversations that had grown more complicated: “those conversations grew more complicated after the executive order as we found solutions, and delayed some of the transactions. But I see the momentum resuming.” — Joseph Dominguez, President and Chief Executive Officer · 2026-03-31 By the August 6 call, that resumed momentum had turned into signatures: “Since the last call, we have signed approximately 920 megawatts of long-term nuclear deals… These contracts have an average duration of 18.5 years and are with investment-grade customers.” — Joseph Dominguez, Chairman, President and Chief Executive Officer · 2026-08-06
The catalyst is the sudden pace of PJM and FERC reform — the reliability backstop procurement (RBP), the Interim Resource Adequacy Service, and co-location rules that FERC is forcing forward despite PJM's earlier 2029 target. Management is emphatic: “we are seeing PJM prompted by FERC move at the necessary speed.” — Joseph Dominguez, Chairman, President and Chief Executive Officer · 2026-08-06 The export of that clarity is now visible in the numbers: roughly 30% of clean baseload is contracted under long-term agreements, with the landmark Walmart transaction — “their first nuclear power purchase agreement and the first transaction of its kind for a major retailer” — Joseph Dominguez, Chairman, President and Chief Executive Officer · 2026-08-06 — a symbolic breakthrough.
The strategic spine of the whole story remains stranded capacity — the claim that the grid is over 99% underutilized and the real problem is merely a handful of peak hours:
We have plenty of unused capacity in generation and in the wires grid over 99% of the hours of the year. We have a peak capacity concern, not an energy concern.
The tape hasn't followed the fundamentals
The contrast is sharp. Guidance was raised, with the midpoint now sitting at the previous top of the range. Yet the stock is down roughly 5% over the last 90 days and sits 32% off its October 2025 peak. The market's shrug is understandable: the new contracts and buybacks are accretive but slow-burning — most nuclear PPAs have later start dates and, as Shane Smith noted, only modest 2029 impact so far — while ERCOT weakness in the forwards tempers enthusiasm. Management was already signaling conviction against that tape on the May call: “ERCOT is undervalued, and we do not think that the prices in the outer years in particular make a great deal of sense.” — Joseph Dominguez, President and Chief Executive Officer · 2026-05-11
The fundamentals do support the operational narrative. The latest filing (Q1, period-end April 30) already captures the Calpine consolidation step-change: total revenue rose 64% year over year to $11.1B, and operating margin expanded to 21.0%, up 14.3 points year over year. The thesis is that as contracting activity compounds, the earnings power behind that margin becomes more visible — and the financial strength of an investment-grade balance sheet, plus roughly $5.9B of expected near-term divestiture proceeds, funds the capital return.
Batch Zero: riding a market-wide wave
Not everything here is Constellation-specific. The ERCOT data-center interconnection process, Batch Zero, is the top market-wide keyword for the quarter, and Constellation is one of several names citing it — “some of our sites are in the Batch Zero process.” — Joseph Dominguez, Chairman, President and Chief Executive Officer · 2026-08-06 Fellow reporters this week — CIFR, Galaxy Digital, and Diamondback — all flagged the same process, confirming Batch Zero is a shared industry theme rather than a Constellation-only edge. Management's positioning is that Texas's batch process is a "temporary measure" — the state remains the epicenter of AI growth, and Constellation's Calpine-derived gas fleet plus first-mover site approvals give it optionality. The bet is that once ERCOT and the PUCT provide clarity, the gas fleet's dispatch economics recover.
Capital allocation: the floor is now visible
Shareholder returns are the other pillar. Year-to-date buybacks total roughly $2.2B, and Shane Smith raised the 2029 capital-allocation floor to $0.20 per share with upside above $0.75 not incorporated — above the prior "+$0.50" sensitivity. The PTC strike-price inflation adjustment adds another $0.30 to 2030 base earnings. It is a coherent, well-telegraphed narrative: lock in nuclear energy at premium prices with investment-grade counterparties, harvest the stranded capacity, return the free cash flow. The open question — and the reason the tape remains skeptical — is whether the "bit of a bang" in deal flow that Dominguez predicts actually materializes: “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.” — Joseph Dominguez, Chairman, President and Chief Executive Officer · 2026-08-06 If it does, this quarter's guidance raise will look conservative.
