### Business Model

- Constellation generates electricity and sells it, along with natural gas and related energy products, to utilities, municipalities, cooperatives, businesses, public-sector organizations, and households. It owns nuclear, natural-gas, oil, geothermal, hydro, wind, and solar power plants and also sells electricity directly to customers; its scale is 55 GW of generating capacity and about 2.5 million customer accounts, including 80% of the Fortune 100. Since acquiring Calpine in January 2026, it also has a nationwide competitive retail electricity platform and a larger fleet of natural-gas and other dispatchable generation. Its six reporting segments are Mid-Atlantic, Midwest, New York, ERCOT, Other Power Regions, and Calpine; the filing reports about $7.5 billion in revenue for the quarter. (+4 more findings) (NEUTRAL)

### Future Growth

- **[CATALYST] Electric Utilities And Grid Infrastructure M&A and Portfolio Action** (POSITIVE, Trend: NEW_TREND): This March-quarter filing predates the acquisition closing, so it provides no post-acquisition Calpine revenue result. It does confirm the proposed scale of the business: over 27 GW of generation and about 60 TWh of annual retail load. The deal remains a proposed, regulatory-conditioned expansion rather than realized growth in this quarter. (2 new trend, 1 steady across 3 signals)

This comparison is materially distorted by lower mark-to-market gains: $64 million versus $929 million. Meanwhile, reportable electric-segment revenue was nearly unchanged at $4.794 billion, up 0.5%, and regional supply/sales volume rose 4.5% to 68,407 GWh.

### Risk Assessment

- Nuclear capacity factor fell to 93.0% in Q2 2026 from 94.8% a year earlier, while refueling outage days increased to 86 from 41. Lower output can reduce sales or require replacement power, pressuring earnings if outages persist or plant performance falls short of expectations. (NEUTRAL)
- **[CATALYST] Electric Utilities And Grid Infrastructure M&A and Portfolio Action** (NEGATIVE, Risk: HIGH): The acquisition was still pending in Q3 2025: DOJ-related timing and customary closing conditions remained, and the transaction involved 50 million new shares, $4.5 billion cash and assumption of about $12.7 billion debt. The filing records $50 million of acquisition-related costs for the first nine months of 2025. The later baseline confirms that integration remains underway and reports materially higher integration costs and goodwill. This risk intensified from the pending-deal stage to a large, ongoing integration challenge. (3 intensifying, 1 stable, 1 high-severity)
  > Operating revenues attributable to Calpine following the Acquisition Date were $1,907 million and $5,043 million for the three and six months ended June 30, 2026.

- **[TREND] Electric Utilities And Grid Infrastructure Policy and Regulation** (NEGATIVE, Risk: MODERATE): In February 2026, PJM proposed extending its existing capacity-market price collar—about $325/MW-day at the cap and $175/MW-day at the floor—for the 2028/2029 and 2029/2030 auctions. FERC accepted that proposal in April 2026. The June baseline further reported that the 2028/2029 auction cleared at the cap, making the limit’s effect on potential upside concrete. This risk intensified as the cap was both extended and reached in the subsequent auction. (1 intensifying, 4 stable)

- **[TREND] Electric Utilities And Grid Infrastructure Supply Chain Reconfiguration** (NEUTRAL, Risk: MODERATE): Nuclear fuel supply remains exposed to geopolitical restrictions and supplier delivery failures. Three suppliers account for a substantial share of uranium needs over the coming years; replacement material may be available but could cost more than contracted supply, potentially affecting nuclear generation costs or availability. [CONCENTRATION]

In the event of non-performance by these or other suppliers, we believe that replacement uranium concentrate can be obtained, although at prices that may be unfavorab

### Scenario Analysis

- Tariffs could raise the cost of imported equipment, maintenance materials, and construction inputs, while export restrictions can complicate nuclear-fuel procurement; the filing quantifies neither tariff costs nor any resulting loss, and reports supplier diversification, advance contracting, and increased fuel inventory as mitigations. If reshoring adds electricity demand, Constellation could gain sales through its generation and retail platforms, but the benefit depends on securing contracts and serving added load economically rather than buying power or absorbing higher transmission and capacity costs. Its 380 MW data-center agreement and large Calpine platform support the ability to serve growth, but neither is shown to result from reshoring. The potential third-order shift is therefore a larger addressable market for reliable power, not an established migration of tariff-driven profit pools to Constellation. (NEUTRAL)
  > Labor, contracting, and materials(a) $ 228 $ 404
__________
(a) Primarily reflects increased employee-related costs, including labor and other incentives, as well as higher contracting expense, driven in large part by the addition of Calpine's operations beginning in January 2026.
- AI-related data-center expansion increases demand for reliable electricity and grid connections, directly matching Constellation’s generation and site-access offering. The CyrusOne arrangements and Microsoft’s long-term PPA provide concrete routes to serve that demand, while higher large-load forecasts may also tighten capacity markets; Constellation’s units cleared at the PJM auction cap, although the contribution from AI cannot be isolated. Meeting this demand requires substantial investment, and the filing does not disclose co-location costs or returns. If projects connect and earn attractive returns, deliverable power and interconnection access could become strategic advantages; if not, large generation scale alone will not secure customer economics. (POSITIVE)
  > The final regulatory clearance for the merger was the DOJ resolution, which requires the divestiture of five generating assets located in PJM, one in ERCOT, and Calpine's minority interest in the Gregory Power Plant, also in ERCOT. The DOJ resolution requires us to enter into definitive agreement(s)
- The clearest first-order exposure is financing: SOFR-linked Calpine project debt and future borrowing costs can rise or fall with rates, although management’s 50-basis-point sensitivity was not material to first-half earnings and swaps provide partial protection. Persistently high rates or wider spreads could still raise refinancing costs and compete with spending on the Crane restart and data-center infrastructure; rate cuts could ease those pressures, but no project sensitivity or rate-driven change in plans is disclosed. A downturn could also weaken counterparties or increase collateral needs, while rate moves affect the value of fixed-income holdings in the nuclear decommissioning trusts. At the third order, changing discount rates may influence how investors value long-lived generation assets and contracts, but the evidence does not support a specific rate-driven earnings or share-price re-rating. (NEUTRAL)
  > Our access to external financing on reasonable terms depends on our credit ratings and current overall capital market business conditions. If these conditions deteriorate to the extent that we no longer have access to the capital markets at reasonable terms, we have access to credit facilities with
