S.N. Nuclearelectrica S.A.

The brief

Nuclearelectrica produces electricity and thermal energy from nuclear reactors at the Cernavoda plant in Romania, selling power to the grid and heat to local industrial and municipal customers [Yahoo Finance]. The company also manufactures nuclear fuel bundles and processes uranium domestically [Yahoo Finance].

S.N. Nuclearelectrica S.A. is Romania's state-controlled nuclear electricity producer, operating the Cernavoda nuclear power plant and selling electricity to the national grid [Yahoo Finance]. The company generates extremely high gross margins (88%) and maintains a debt-free balance sheet, though trailing revenue has declined 5.3% year-over-year [Yahoo Finance]. With the Romanian state holding 82.5% of shares and only two analysts covering the stock—both rating it 'underperform'—this is a thinly-followed utility with limited institutional presence [Yahoo Finance].

Debt-free balance sheet and enormous profitability margins, but revenue contracted in the trailing period and operating margin swung wildly quarter-over-quarter.

Figures come from company filings and market data. The Sentinellis health score and the wording attached to it are our interpretation of those figures, not numbers the company reported.

Not investment advice and not a recommendation to buy or sell. Sentinellis holds no positions in the companies it covers, takes no payment from issuers, and has no broker referral arrangements.
