Thalassa Holdings Ltd, a London-listed investment holding company, reported a £0.36 million loss for the first half of 2026, reversing a £0.01 million profit in the same period a year earlier. The results reflect broader operational challenges, including a £0.3 million operating loss compared to an £0.1 million profit in H1 2025. Basic and diluted earnings per share turned negative at £0.02, down from £0.00 in the prior year, while book value per share fell to £0.51 from £0.60, reflecting a decline in net assets to £8.5 million from £10.1 million. Investment holdings excluding cash decreased to £9.0 million from £10.3 million, and cash balances dropped to £0.1 million from £0.3 million. Administrative expenses remained stable at £0.4 million, though the company’s overall financial health has weakened amid operational and strategic shifts.
The company’s subsidiaries have faced notable developments. Autonomous Robotics Limited, developing the Flying Node autonomous underwater vehicle, has delayed its third or fourth quarter 2026 completion due to technical issues related to motherboard condensation. Meanwhile, Thalassa sold its Safetell division to Newmark Security’s CEO for £1, extending a £2 million loan to the buyer. The divestiture aligns with broader portfolio adjustments, including a 23% holding in Surgical Innovations Group PLC, a UK-based medical products firm.
Thalassa Holdings remains focused on its core investment strategy, though the recent results underscore the need for continued operational efficiency and strategic realignment to mitigate losses and improve profitability.
