§Winston Score History

The full picture

The Mosaic Company mines and sells two key nutrients that farmers use to grow crops: potash and phosphate. These minerals go into fertilizers that help plants grow faster and produce more food. Mosaic is one of the largest producers of both potash and phosphate in the world, selling mostly to farmers and agricultural distributors across North and South America.

Mosaic makes money by mining these minerals and selling them by the ton to fertilizer blenders, distributors, and large farming operations. The company operates mines and processing plants mainly in the United States, Canada, and Brazil, with Brazil being a growing part of its business. Its competitive edge comes from owning large, long-life mineral deposits that are expensive and difficult for competitors to replicate. The main risk the company faces is that fertilizer prices are highly volatile and tied to global supply, natural gas costs, and crop commodity prices — all factors largely outside Mosaic's control.

Revenue declining

The Mosaic Company'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.
