Share count rising — dilution

+20.2% over 4y

The company has issued more shares over this period, which dilutes each existing shareholder’s stake.

Diluted shares outstanding: 102.8M (2021) → 123.6M (2025)

United States Antimony Corporation mines and processes antimony, a metal used to make flame retardants, batteries, and ammunition. It also produces zeolite, a mineral used in water filtration and agriculture. The company is one of the only domestic producers of antimony in the United States, which has become strategically important as China controls most of the world's antimony supply.

The company sells its products to industrial manufacturers and government-linked buyers across North America, and it operates mines and processing facilities in Montana, Idaho, and Mexico. Its competitive position comes largely from being a rare US-based source of a critical mineral rather than from scale or cost advantages. However, the company currently loses money on operations, with a negative operating margin near 42%, and its ability to grow depends heavily on whether antimony demand from defense and energy storage industries expands fast enough to offset its high production costs.

Strong grower

United States Antimony Corporation is growing revenue at 90% year-over-year. The Winston Score penalises unprofitable companies, but revenue at this pace tells a different story — this is a company still in "build mode."

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.
