3 UK Penny Stocks With Market Caps Over £90M

Simply Wall St

The United Kingdom's stock market recently faced challenges as the FTSE 100 and FTSE 250 indices declined, influenced by weak trade data from China and its impact on commodity prices. Despite these broader market pressures, penny stocks—often representing smaller or newer companies—remain an intriguing area for investors seeking growth opportunities at lower price points. While the term "penny stocks" may seem outdated, these investments can still offer potential when backed by strong financials and solid fundamentals.

Market Cap: £370.51M

Pensana Plc, with a market cap of £370.51 million, operates in mineral exploration and development in the UK and Angola. The company is pre-revenue, making less than US$1m annually. Despite this, it maintains a satisfactory net debt to equity ratio of 31.8% and has sufficient cash runway for over three years even as its free cash flow shrinks slightly each year. However, its short-term liabilities ($27.5M) significantly outweigh short-term assets ($2M). While trading below estimated fair value by 18.3%, Pensana's share price remains highly volatile with negative return on equity at -10.89%.
