SDI Group (LSE:SDI) reported strong results for the year ended 30 April 2026, with revenue increasing 12.6% to £74.5 million, driven by a combination of organic growth and contributions from recently acquired businesses. Adjusted operating profit rose 16.1% to £11.6 million, while operating margins improved as the company benefited from healthy demand across its core markets and increasing collaboration between businesses within the group.
During the year, SDI continued to expand through acquisitions, completing the purchases of Severn Thermal Solutions and PRP Optoelectronics as part of its long-term buy-and-build strategy. The company also renewed its £25 million revolving credit facility, which includes a £15 million accordion option, providing additional financial flexibility to pursue future acquisition opportunities. Management said the group enters the new financial year with strong momentum, supported by a broader market presence, a growing pipeline of opportunities and a strategy designed to deliver sustainable long-term shareholder value.
While SDI’s financial performance and growth strategy remain key strengths, the company noted that technical market indicators continue to be less supportive and valuation appears more balanced. Continued revenue growth, successful acquisitions and positive operational performance provide a solid foundation for future expansion, although competitive market conditions and higher borrowing levels following acquisitions remain factors to monitor.
