Kromek Group plc makes detectors that spot radiation and biological threats, used in medical scanners, security screening and defence. In the year to 30 April 2026 its revenue rose 2.3% to £27.1m. Profit after tax fell to £733k, from £3.8m the year before.

The main reason was less income from a highly profitable licensing deal with Siemens Healthineers, which brought in £10.0m of revenue against £16.5m a year earlier. Sales were also helped by a one-off large order from an existing imaging customer. The defence and security detection business grew. Lower costs, including smaller charges for unpaid bills and fewer one-off fees tied to the Siemens deal, softened the fall in profit.

Cash at the year end was £4.2m, up from £1.7m, but borrowings rose to £5.7m, so the company owed more than it held. Almost no new money was raised from shareholders, and no dividend was paid. Management expects revenue to grow for a sixth year running and "significant underlying growth" in the year ahead. The auditor raised no doubt about the company's ability to keep going.

What moved the marginheadwind

Enablement Agreement licensing revenue mix

Gross margin fell to 62.8% (2025: 80.9%) due to revenue mix, including high-margin licensing revenue accounting for a higher proportion of revenue in 2025 vs 2026; management expects margins to return to mid-50s in FY2027 as this reverts to the historical underlying level
