Winston Score History

The full picture

Arq, Inc. is a small industrial company that makes products to reduce pollution. Its main product is activated carbon, a material used to filter harmful chemicals and mercury out of emissions from coal-fired power plants and industrial facilities. Arq also produces a refined coal-based material it calls "Arq powder," which it is working to turn into new products for fuel and other uses.

The company earns revenue by selling activated carbon products to power plants and utilities, primarily in the United States. With a market cap of around $100 million, Arq is a small player in the pollution control industry, and its competitive position depends heavily on environmental regulations that require power plants to limit mercury emissions. The company is currently unprofitable at the operating level, and its biggest risk is that tighter regulations could be rolled back or that demand from coal plants could shrink as the power sector shifts toward cleaner energy sources.

Cash watch

Arq has less than a year of cash at its current burn rate. Growth investors should watch for potential share dilution from future fundraising — that directly reduces your ownership.

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.
