Winston Score History

The full picture

Byrna Technologies makes non-lethal personal security devices. Its main product is a handheld launcher that shoots chemical irritant projectiles — similar to a pepper spray but in a small gun-like form. The company sells to everyday consumers who want home or personal defense options, as well as to law enforcement agencies and security professionals. Byrna operates in the personal defense and non-lethal weapons industry, positioning itself as an alternative to traditional firearms.

Byrna earns money primarily by selling its launchers, projectile ammunition, and accessories directly to consumers through its website and retail partners. The company operates mainly in the United States but has expanded into international markets including Europe and Latin America. Its moat comes from its brand recognition in a niche category and its proprietary projectile chemistry, though it is still unprofitable at the operating level. The key growth driver is rising consumer interest in non-lethal self-defense, while the main risk is competition from both traditional firearms and other less-lethal alternatives.

Revenue declining

Byrna Technologies'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.
