Market Cap: €20.79M

Windon Energy Group AB, with a market cap of €20.79 million, operates in the energy sector and has shown some revenue growth despite its unprofitability. Recent earnings for the second quarter of 2025 reported sales of SEK 9.2 million, marking an increase from SEK 7.82 million a year earlier; however, the company continues to incur net losses (SEK 2.5 million). The stock remains highly volatile with weekly volatility decreasing yet still higher than most German stocks. Windon is debt-free and has sufficient short-term assets to cover liabilities but lacks significant revenue streams and profitability indicators common among penny stocks.
