3 UK Penny Stocks With Market Caps Under £300M To Consider

Simply Wall St

The UK market has recently faced challenges, with the FTSE 100 and FTSE 250 indices slipping due to weak trade data from China, highlighting the interconnectedness of global economies. In such times, investors might consider exploring penny stocks—an investment area that remains relevant despite its somewhat outdated name. These smaller or newer companies can offer hidden value and potential growth, especially when they are built on solid financial foundations.

Kromek Group (AIM:KMK)

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

Overview: Kromek Group plc, with a market cap of £39.95 million, develops, manufactures, and sells radiation detection components and devices for advanced imaging, CBRN detection, and biological threat detection markets.

Operations: Kromek Group generates revenue from two primary segments: Advanced Imaging, contributing £27.83 million, and CBRN/Biological-Threat Detection, contributing £7.66 million.

Market Cap: £39.95M

Kromek Group plc has demonstrated significant financial improvement, transitioning to profitability with a net income of £3.75 million for the year ending April 2025, compared to a loss previously. The company benefits from strong short-term asset coverage over liabilities and reduced debt levels, maintaining more cash than total debt. However, its Return on Equity remains low at 7.2%, and interest coverage by EBIT is slightly below ideal levels. Recent contracts with the UK Ministry of Defence and Siemens Medical Solutions highlight strategic growth in revenue streams across advanced imaging and CBRN detection segments, supporting future revenue expectations despite forecasted earnings decline.

Next 15 Group (AIM:NFG)

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

Overview: Next 15 Group plc provides customer insight, delivery, engagement, and business transformation services across the UK, Africa, the US, Europe, and the Middle East with a market cap of £273.51 million.

Operations: The company's revenue is derived from four main segments: Customer Engage (£340.56 million), Customer Insight (£73.87 million), Customer Delivery (£171.19 million), and Business Transformation (£144.19 million).

Market Cap: £273.51M

Next 15 Group plc, with a market cap of £273.51 million, presents a mixed picture for investors in penny stocks. The company has experienced significant profit growth over the past five years but faced negative earnings growth recently due to a large one-off loss of £16.8 million. Despite trading at 73% below its estimated fair value, it struggles with short-term liabilities exceeding assets and an unstable dividend track record. However, its debt is well covered by operating cash flow and interest payments are adequately managed by EBIT. Recent board changes could impact strategic direction moving forward.

Springfield Properties (AIM:SPR)

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

Overview: Springfield Properties Plc, with a market cap of £117.85 million, operates in the United Kingdom as a house building company through its subsidiaries.

Operations: Springfield Properties does not report distinct revenue segments.

Market Cap: £117.85M

Springfield Properties Plc, with a market cap of £117.85 million, offers potential as a penny stock due to its strong earnings growth of 86.8% over the past year and trading at good value compared to peers. The company reported increased sales of £280.56 million and net income of £14.1 million for the fiscal year ended May 31, 2025. Its debt management is robust, with well-covered interest payments and reduced debt levels over time. However, its Return on Equity remains low at 8.2%, and earnings are forecasted to decline by an average of 5.3% annually over the next three years despite recent dividend increases reflecting financial stability.
