Headquartered in Blaby, Leicestershire, TEK4 Group plc (TEK4) is a UK precision engineering business that designs, manufactures and supports specialist cooling-hole drilling systems used in the production of aero engine and industrial gas turbine components.
TEK4 provides customers with a broad suite of cooling-hole manufacturing solutions from a single supplier, including electrical discharge machining (EDM) drilling, laser ablation and shaped tube electrolytic machining (STEM/ECM). In April 2026, TEK4 acquired Innolas (UK) Limited, adding femtosecond laser and micromachining capabilities and supporting its entry into adjacent medical device and semiconductor applications.
The placement raised approximately £24.75 million, comprising £2.0 million (before expenses) from the issue of new ordinary shares and £22.75 million from the sale of existing shares, giving the company an anticipated market capitalisation of £42.0 million on admission.
