Share count rising — dilution

+83.2% over 4y

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

Diluted shares outstanding: 117.4M (2021) → 215.0M (2025)

Magna Mining Inc. is a Canadian mining company focused on exploring and developing nickel, copper, and cobalt deposits in the Sudbury Basin of Ontario, Canada. Sudbury is one of the world's most prolific mining regions, and Magna holds several properties there, including the Shakespeare and Crean Hill projects. The company targets metals that are used in electric vehicle batteries and industrial applications.

Magna Mining makes money by eventually selling mined metals, but it is still in the exploration and development stage, meaning it is not yet generating meaningful revenue from production. This explains its negative margins — the company is spending money to advance its projects without significant sales coming in yet. Its competitive position rests on owning properties in a proven mining district with existing infrastructure nearby, which lowers development costs. The key growth driver is advancing its projects toward production, but the main risk is that doing so requires raising additional capital, which can dilute existing shareholders.

Magna Mining is growing revenue at 482% 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.
