Deep Value: cash covers more than 100% of the stock price

This company holds roughly $50M in cash and investments — more than its entire stock-market value, based on its latest quarterly filing. You're paying very little for the actual business. Sometimes that's a genuine bargain or a takeover target, sometimes it's cheap for a reason. Not a buy signal on its own — always ask why it's this cheap.

Winston Score History

The full picture

Hydrogène de France (HDF Energy) is a French company that builds large power plants using hydrogen as fuel. These plants take hydrogen and convert it into electricity using fuel cells, which can then power homes, businesses, or remote areas that do not have reliable access to the electrical grid. The company targets customers in developing regions, island territories, and industrial sites that need stable, clean electricity.

HDF makes money by developing, building, and eventually operating these hydrogen power plants, earning revenue from long-term energy supply contracts. The company is based in France and focuses mainly on projects in Africa, the Caribbean, and the Pacific. Its main competitive edge is its proprietary Renewstable technology, which combines renewable energy with hydrogen storage to deliver steady power around the clock. However, the company is still in an early stage and is not yet profitable, as shown by its deeply negative margins, and its key risk is securing enough project financing and customers to scale before it runs out of capital.

Revenue declining

Hydrogène de France S.A.'s revenue is actually shrinking. In a growth stock, that removes the core investment thesis. The low Winston Score here may be warranted — unless there's a turnaround story.

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.
