The three available forensic readings need to be read together. The Altman Z″-Score of 1.54 falls in the grey zone, the band the label defines as between 1.10 and 2.60. That places it between the ranges usually labeled distress and safe, so it works as a screening signal rather than a verdict on solvency, and it was computed on 2025 figures that exclude Calpine. The operating cash flow to net income ratio of 1.83 means 2025 operating cash flow of $4.24 billion was well above net income of $2.32 billion, which suggests reported profit was backed by cash in that year. That is a favorable reading, but the five-year table shows operating cash flow negative in 2021, 2022, 2023 and 2024, so one strong year does not establish a pattern. The Beneish M-Score, Piotroski F-Score and Fog Index are not on file for this company, so this synthesis gives no value or reading for them. On the business side, the filing reports 31,676 MWs of owned capacity at December 31, 2025, and a 2025 nuclear capacity factor of 94.7%. The Crane Clean Energy Center restart, supported by a 20-year Microsoft PPA for about 835 MWs, depends on regulatory approvals, interconnection work, permitting and a renewed operating license, and a DOE guarantee of up to $1.0 billion supports it. Readers may want to look at how the Calpine integration will change the 2026 balance sheet, since the 2025 liabilities of $42.4 billion and equity of $14.52 billion do not include it. Equity rose from $13.17 billion in 2024 while long-term debt eased from $7.38 billion to $7.25 billion, a point in the filed balance sheet's favor.

Catalyst.The 10-K describes the January 7, 2026 Calpine acquisition, which added approximately 23 GWs across 72 generation and battery storage assets and about 62 TWhs of annual retail load, as the central change to the company's scale. The 2025 results reported before that closing show revenue of $22.66 billion, up 19.5% from $18.96 billion in 2024, and operating cash flow of $4.24 billion against negative $2.46 billion a year earlier. The filing also cites 4,798 MWs of contracted generation and a nuclear fleet of about 22 GWs that produced 183 TWhs in 2025. Recent news headlines link the company to AI-linked power contracts, including a 380-megawatt deal with CyrusOne announced February 26, 2026.

Hidden risk.Revenue rose 19.5% to $22.66 billion in 2025, yet operating income fell to $3.09 billion from $4.35 billion and net income fell to $2.32 billion from $3.75 billion, a 38.1% decline in net income. The nine-month figures in the 10-Q show purchased power and fuel costs rising to $11.08 billion from $8.83 billion, a 25.5% increase, which squeezed margins while revenue grew. Operating cash flow was negative in each of 2021 through 2024, and the positive $4.24 billion in 2025 is the first positive year since 2020 in the data provided. The Altman grey-zone reading adds caution. Readers may want to look at the MD&A discussion of purchased power and fuel costs, since the excerpts provided do not fully show it.
