Winston Score History

The full picture

NeurAxis is a small medical device company that makes a product called IB-Stim, a nerve stimulation device worn behind the ear. It is designed to help children and teenagers who suffer from a painful stomach condition called irritable bowel syndrome (IBS). The device works by sending gentle electrical signals to the vagus nerve, which can help reduce abdominal pain. NeurAxis sells primarily to pediatric gastroenterologists and clinics across the United States, and IB-Stim holds FDA clearance specifically for use in patients aged 11 to 18.

The company earns revenue by selling the IB-Stim device directly to healthcare providers and through insurance reimbursement pathways. It operates entirely in the United States and is very small, with a market cap around $100 million. The high gross margin reflects the typical medical device model, but the deeply negative operating margin shows the company is spending far more than it earns. The key challenge is expanding insurance coverage and physician adoption broadly enough to reach profitability before the company runs out of cash.

Revenue accelerating

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.
