AI snapshot
Six angles, distilled from the data.
The stock is in a constructive recovery regime, holding above its 200-day average of 1.155 and near the upper end of its 52-week range of 1.00 to 1.29. The setup still needs follow-through, but the longer-term trend has improved versus the prior base.
Street coverage is effectively absent, with no consensus rating or target price on file. There have been no recent rating changes, so the shares are being driven more by fundamentals and market structure than by analyst sentiment.
Next results are set for 2026-12-03, and the forward path points to steady improvement. Revenue estimates rise from 75.5 million for 2026 to 80.6 million for 2027, while EPS is modeled to edge up from 0.070 to 0.076, so shareholders should watch margin discipline and conversion of sales into cash.
No notable insider activity. There have been no recent transactions, so there is no visible discretionary buying or selling signal to read into.
Profitability is solid for a small-cap industrial technology name, with gross margin at 66.0% and operating margin at 12.27%. Growth is still healthy, with revenue up 14.7% year over year and earnings up 10.1%, while free cash flow of 8.14 million supports the business.
SDIIF sits in the scientific and technical instruments niche, where product breadth and niche applications can support pricing power. At 18.77 times earnings, valuation looks moderate rather than stretched for a profitable niche hardware business.

SDI Group posted record FY26 revenue growth, improved margins and cash generation, and said FY27 should be in line with market expectations.· July 29, 2026
- Group revenue reached circa GBP 75 million, the highest in SDI’s history, with about 13% growth and over 5% organic growth for the full year.
- All three divisions grew in FY26, led by Industrial & Scientific Sensors up 23% to GBP 21 million and Laboratory Equipment up more than 12% to GBP 27 million.
- Adjusted EBITDA improved to GBP 14.1 million and adjusted operating profit to GBP 11.6 million, while net operating margin rose to 15.5%.
- Cash generated from operations exceeded GBP 10 million, but year-end net debt increased to GBP 24 million after the PRP acquisition.
- Management said FY27 has started strongly and expects full-year performance in line with market expectations, with a smoother H1/H2 profile than FY26.
SDI said FY26 group revenue was circa GBP 75 million, up circa 13% year over year, with organic revenue growth of 5.3% on a constant-currency basis for the year and 6.7% in the second half alone. Adjusted EBITDA improved to GBP 14.1 million, adjusted operating profit rose to GBP 11.6 million, gross profit margin increased to 66% on materials only, and like-for-like gross margin improved from 64.9% to 65.7%. Net operating margin rose from 15% to 15.5%, adjusted tax rate was unchanged at 22.7%, and cash generated by operations was GBP 10.2 million versus GBP 12.9 million last year. Year-end net debt was GBP 24 million, leverage was 1.7x net debt to EBITDA, and the company said it has GBP 25 million of committed funding through November 2028 plus a GBP 15 million accordion, with GBP 9 million still available after funding PRP. Looking ahead, management expects FY27 performance to be in line with market expectations; they also said the first half of FY27 has started strongly and is looking like a smoother split than last year.
Stephen Brown framed FY26 as a year of momentum, saying SDI moved beyond resilience to delivering growth and that the strategy is working. He emphasized the compounding buy-and-build model, operational excellence, cross-selling, ERP investment, and expanded management capacity as key pillars for future growth. On the outlook, he said the group entered FY27 with strong momentum, a robust acquisition pipeline, and confidence in sustainable long-term value creation.
Ami Sharma highlighted that the year was second-half weighted, driven by the timing of deliveries on large contracts. He noted adjusted EBITDA of GBP 14.1 million, adjusted operating profit of GBP 11.6 million, margins improving to 15.5%, and gross margin improvement to 66% on materials only, with pricing remaining a focus. On cash and debt, he said operations generated GBP 10.2 million, working capital absorbed GBP 3 million, net debt ended at GBP 24 million, leverage was 1.7x, and the bank facility was refinanced to provide GBP 25 million committed funding through November 2028 plus a GBP 15 million accordion option, of which GBP 6 million was used for PRP.
Analysts asked about the new 13% shareholder, bigger acquisition sizes, AI risk, receivable days, acquisition funding, debt levels, and how sustainable the second-half momentum is. Management said the new shareholder appears supportive and engaged, that future acquisitions are more likely to stay in the GBP 1 million to GBP 1.5 million EBIT range rather than get bigger, and that acquisitions are currently funded with debt and then paid down through cash flow. On AI, Stephen Brown said SDI’s niche manufacturing businesses are not easily replaceable by AI, but the group is actively adopting AI where it adds product or operational value. On momentum and debt, management said debtor days remained at 44, leverage is below the 2.5x limit, and FY27 should have a more even H1/H2 split than FY26, with a strong start to the year.
The call showed broad-based growth across all three divisions, record revenue, improving margins, and solid cash generation. Management also signaled confidence in FY27, citing a strong start to the year, a healthy order book, renewed financing capacity, and a pipeline of bolt-on acquisitions.
FY26 cash generation was down from GBP 12.9 million to GBP 10.2 million, and year-end net debt rose to GBP 24 million after the PRP deal. Management also noted pressure from higher employee costs, minimum wage, and the apprenticeship levy, while some businesses such as Synoptics and Scientific Vacuum Systems faced softer trading or a slower period.
