|---|---|---|---|---|

| Bull | 20 % | 495.69 (+81 %) | 641.19 (+135 %) | 785.53 (+188 %) |
| Weighted | 100 % | 360.17 (+32 %) | 398.00 (+46 %) | 436.40 (+61 %) |
What this means. The weighted row is the probability-based average of the bear, base, and bull cases, not a guaranteed share price.
What has to go right or wrong for Constellation's forecast?
The bear case starts at $6,500M and slips to $6,300M before recovering to $6,700M. The bull case starts at $8,200M, reaches $9,600M, and ends at $11,000M. The anchor is guidance-implied operating profit of about $6,740M, while first-half 2026 operating income was $2,912M. The bear assumes weaker merchant margins and delayed growth; the bull requires strong nuclear availability, uprates, demand, and smooth Calpine integration.
How much cash does Constellation really make?
Free cash flow subtracts capital spending from operating cash flow. A stricter analytical measure also subtracts stock compensation, because employees receive part of shareholders’ claim even though that payment does not consume the same period’s cash. Both measures are useful, but neither proves that all residual cash can be distributed.
| 2025 | 2024 | 2023 | 2022 | 2021 | |
|---|---|---|---|---|---|
| Cash from operations | 4,237 | -2,464 | -5,301 | -2,353 | -1,338 |
| − Capital spending | 2,949 | 2,565 | 2,422 | 1,689 | 1,329 |
| = Free cash flow | 1,288 | -5,029 | -7,723 | -4,042 | -2,667 |
| − Stock pay | 385 | 332 | 178 | 116 | 47 |
| = Real free cash flow | 903 | -5,361 | -7,901 | -4,158 | -2,714 |
| Real free cash flow, % of revenue | 3.5% | -22.7% | -31.7% | -17.0% | -13.8% |
What this means. Some cash collected from customers is shown under investing activities, so it is left out of the operating cash flow and free cash flow calculation.
What does an investor pay for Constellation today?
The P/E ratio compares the share price with earnings per share. The trailing version uses the last twelve months; the forward version uses an estimate for the next twelve. The lower forward multiple therefore assumes earnings will rise. But earnings are accounting results, not a cash meter: power prices, outages, hedges and environmental credits can change them, while fair-value accounting can record contract gains or losses before cash arrives. In the second quarter of 2026, GAAP earnings were $1.42 per share while adjusted operating earnings were $2.55, so the chosen denominator matters.
| Today (Oct 15, 2026) | |
|---|---|
| Share price | 275.00 |
| Market value (calculated) | 97,434.53 |
| Enterprise value (calculated) | 121,437.53 |
| P/E, last 12 months (calculated) | 26.8x |
| P/E, next 12 months (calculated) | 20.7x |
| Real free cash flow yield (calculated) | 0.9% |
What this means. Enterprise value is higher than market value because it includes the company's debt after subtracting its cash.
