Soluna Holdings is a company that builds and operates data centers that run on renewable energy, mainly wind and solar power. Its main customers are cryptocurrency miners and, increasingly, artificial intelligence computing companies that need large amounts of cheap electricity. The company focuses on "stranded" renewable energy — power that is generated in remote areas but cannot easily be sent to the grid.

Soluna makes money by selling computing power and electricity capacity to customers who run energy-intensive workloads, essentially acting as a host for their hardware. The company operates primarily in the United States and is relatively small, with a market cap around $300 million. Its competitive angle is locking up low-cost renewable energy that others cannot easily access, but the business currently loses significant money, as shown by its deeply negative operating margin. The main risk is that cryptocurrency prices and AI computing demand are both volatile, which makes revenue unpredictable.

Revenue accelerating

Soluna Holdings grew revenue 58% year-over-year and the growth rate is speeding up. That's the kind of momentum growth investors look for — the question is whether margins can follow.

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
