Shaanxi Energy Investment Co., Ltd.

Coal is sold under individually agreed contracts and recognized once it ships and the buyer accepts it, while electricity and heat are billed monthly from metered or grid-confirmed volumes at agreed tariffs. Electricity is by far the largest source of revenue, coal sales are a secondary source and heat a minor one, and the company has recorded a profit in every year on record.

It scales mainly by adding new generating units and mines, projects that take years to build and must clear government approval before they add to revenue, rather than by simply running existing plants harder. Among the wide group of similarly structured companies CompanyGraph tracks, its returns on capital and operating margin sit toward the higher end over a multi-year view, and it turns sales into cash, and that cash into free cash flow, at an unusually high rate both against that group and against its own past.

It depends on coal, part of which comes from its own mines through direct mine-to-plant pairings and part of which it buys externally from a short list of large, named coal and energy suppliers, alongside power-generation equipment bought from named equipment manufacturers. CompanyGraph's mapping of the industries that feed into it shows only a small number of such upstream industries, fewer than the number it supplies outward.

A single buyer, the national grid operator, accounts for the large majority of its sales in the year disclosed, well beyond any other named customer, with a handful of other named industrial and utility buyers making up the rest. CompanyGraph's mapping shows it supplying several downstream industries overall, but its actual revenue is concentrated in that one counterparty far more than a simple count of downstream industries would suggest.

Its profitability and cash conversion sit toward the top of a wide group of other companies that CompanyGraph reads as running the same kind of coal-extraction-to-power system, which reflects a shared way of operating rather than evidence that these companies move together or compete directly. The company itself attributes this position to its location within Shaanxi's coal-producing area, the coordination between its own mines and its own power plants, and the size of the coal reserves it has retained there.

CompanyGraph's default expectation for a coal-extraction business is that the binding limit is the cost of replacing depleted reserves. This company's own account points elsewhere: it describes its retained coal reserves as ample and ranking among the largest in the province, and instead names government approval of new mines and power plants, access to well-located project allocations, and a demand-side ceiling from renewable capacity outgrowing electricity demand, as what actually shapes how much it can add.

The company's own disclosures show the large majority of a year's sales flowing through a single buyer, the national grid operator, so that buyer's purchasing and payment behavior has an outsized effect on the business even though the company describes that counterparty's credit as reliable. It also names safety incidents in coal mining as its foremost risk, a concern its own filings corroborate with an actual safety penalty in the same year, alongside a separately named risk from the shift toward market-based electricity pricing and renewable competition.

The company's own risk disclosures name safety regulation in coal mining as its first-listed pressure, followed by the wider energy system's shift toward non-fossil generation, the volatility of coal prices as an input cost, and the move toward market-based rather than fully administered electricity pricing. It specifically describes renewable generation capacity growing faster than electricity demand as pressure on how many hours its coal-fired plants run, and its own filings record an actual safety penalty during the year alongside the general safety risk it names.
