NIOX Group

Simply Wall St Financial Health Rating: ★★★★★★

Overview: NIOX Group Plc designs, develops, and commercializes medical devices for asthma diagnosis, monitoring, and management globally with a market cap of £258.92 million.

Operations: The company generates revenue primarily from its NIOX® segment, totaling £41.8 million.

Market Cap: £258.92M

NIOX Group, with a market cap of £258.92 million, has seen its earnings decline by 64.2% over the past year despite being profitable over the last five years with annual earnings growth of 60.6%. The company is debt-free and has sufficient short-term assets to cover liabilities, but its net profit margin decreased to 8.1% from 25.8% last year. Recent volatility in share price and a failed acquisition attempt by Keensight Capital highlight potential instability in investor sentiment, though NIOX trades below fair value estimates and forecasts suggest significant future earnings growth at 36.84% annually.
