Electro Optic Systems — Positioned for drone defence
Electro Optic Systems (EOS) is a specialist defence business focused on remote weapons systems (RWS) and counter drone systems. The group is set to benefit from increased defence spend globally along with the rapid emergence of drone warfare and the subsequent requirement for asset protection systems. A strong balance sheet and restructured cost base provide a solid platform through which these opportunities can be leveraged.

DUG Technology — Sorting signal from the noise
DUG Technology (DUG) provides seismic data processing services and software primarily to the oil and gas industry. As a small but innovative player in the field, the recent launch of elastic multi-parameter full waveform inversion (MP-FWI) technology gives the company the opportunity to gain market share despite the uncertain industry outlook. The recent Q325 update confirmed that order intake has returned to growth, supporting our forecasts for a recovery in revenue and profitability from FY26. In our view, this is not factored into the current share price. Uptake of solutions for immersion cooling and mobile high-performance computing (HPC) could provide further upside to our forecasts and valuation.
