Judges Scientific: a tiny AIM listing that became a buy-and-build

What is Judges Scientific and why does it matter to a small holding company?

Judges Scientific plc (AIM: JDG) describes itself as a group that acquires and develops companies in the scientific instrument sector. It buys niche manufacturers at what it calls disciplined multiples of earnings and then lets them run on a decentralised organic growth model. In its 2025 results the outgoing chief executive, David Cicurel, describes its progress as coming from a company with a market capitalisation of only £2 million. The group says it has acquired 25 businesses since 2005.

It matters here because it started tiny, on a junior market, with a very small first deal. Its interim results for 2003 say it was floated on AIM on January 7, 2003, after raising £2 million, or £1.8 million after costs (September 2003 interim results). Its 2003 results describe it then as an investor taking strategic stakes in undervalued quoted companies, with a focus on public-to-private deals (March 2004 results). It shows what a patient buy-and-build can become, and it shows that even a well-run version has bad years.

What did it do, by the numbers?

• January 2003. Floated on AIM as Judges Capital PLC, raising £2 million gross (£1.8 million net). At December 31, 2003 shareholders' funds were about £1.69 million (2003 interims, 2003 results).
• 2005. The company announced on April 29, 2005 that buying Fire Testing Technology (FTT) for about £3.7 million, plus a working capital adjustment, would be a reverse takeover under the AIM Rules (acquisition and placing announcement). Shareholders passed the resolutions on May 23, 2005, and admission of the enlarged share capital of 3,462,356 shares was applied for, with dealings expected from May 24, 2005. The announcement refers to an AIM admission document dated April 29, 2005 (May 2005 announcement). FTT's turnover for the year to May 31, 2004 was about £2.84 million.
• Year to December 2005. Turnover was £2,211,521 (2004: nil) and operating profit was £125,995. A £956,000 placing at 100p helped fund the FTT purchase. The company also bought 51% of PE.fiberoptics and, in February 2006, UHV Design. The results said it had moved away from an earlier role as a catalyst for public-to-private deals (results announced March 21, 2006).
• 2024. Revenue was £133.6 million. Three businesses were acquired that year (Teer Coatings, Luciol and Rockwash). The 2025 announcement's cash flow statement shows £16.5 million spent on acquisitions of subsidiaries in 2024, net of cash acquired.
• 2025. Revenue was £145.8 million (+9.1%) and adjusted operating profit was £28.0 million (2024: £27.9 million). Adjusted basic earnings per share were 275.3p (283.4p). The total dividend was 115.0p (104.5p). Adjusted net debt was £42.6 million (£51.7 million). Return on total invested capital was 17.8% (16.5%). The figures were unaudited when published (2025 results announcement).

Over 19 years the group reports compound annual growth of 19% in revenue, 23% in EBIT and 21% in the dividend, with organic growth of 7% and 8% for revenue and EBIT.

What worked, or what went wrong?

What worked

• A small start. The listed shell raised £2 million in 2003, and the first operating business, FTT, had turnover of about £2.84 million before it was bought.
• Steady additions: 25 businesses since 2005, with management teams left in place under a decentralised model.
• Returns to owners. The group reports total distributions equal to 9.8 times the 2005 re-admission price of 100p.

What the 2025 results show as pressure

• Adjusted operating profit rose only 0.4% in 2025 and adjusted earnings per share fell 2.9%.
• North America revenue fell from £32.9 million to £26.2 million, a drop of about 20%, while the Rest of the World rose from £32.8 million to £43.1 million.
• The cash flow statement shows no spending on new subsidiaries in 2025. The announcement says deals were frustrated by the sector climate and that sellers were not hurrying. The notes say a subsidiary, Geotek Limited, bought the 18% minority stake in Geotek do Brasil on December 3, 2025.
• The results were unaudited because the auditors had not finished in time, and a chief executive succession was announced in November 2025.

None of this says the model failed. It says a buy-and-build depends on a supply of willing sellers as well as on the buyer's capital.

What does and does not transfer to a small holding company?

What transfers

• Start with one small, profitable, owner-run niche business and prove the process.
• Leave management in place and keep the centre small. The group describes its centre as a team that helps the subsidiaries.
• Pay a price you can justify on earnings. The group does not publish its multiples, so there is no number to copy.

What does not transfer

• Two decades. The group's record runs from a 2003 flotation and a 2005 first acquisition, not a quick plan.
• The market. AIM is a London junior market with its own rules. A US holding company faces different listing and reporting rules, covered in Nasdaq listing requirements in 2026.
• The niche. All the businesses make scientific instruments. A holding company in other sectors cannot assume the same margins.

What do the numbers mean in a small-scale example?

Three ratios come straight from the 2025 figures. Adjusted operating profit of £28.0 million on revenue of £145.8 million is a margin of 19.2%. Revenue spread over 25 acquired businesses is about £5.8 million each, which is roughly twice FTT's £2.84 million turnover when it was bought (£145.8 million / 25 = £5.83 million). The 115.0p dividend is about 42% of adjusted basic earnings per share (115.0 / 275.3).

The averages ignore any business that was merged, so treat them as rough. My view is that the useful lesson is the second ratio: the typical unit in this group is small, and the group's size comes from the count and the time, not from big deals.

Where these numbers come from: 2025 and 2024 figures, the 19-year growth rates, the 25 businesses, the £2 million market capitalisation remark, the 100p re-admission price and the Geotek and succession points are from the group's 2025 results announcement, checked against the same announcement on ticker.app. Year-to-December-2005 figures, the £956,000 placing and the early acquisitions are from the results announced March 21, 2006. The January 7, 2003 flotation and £2 million raised are from the September 2003 interim results, and the 2003 business description and shareholders' funds from the March 2004 results. The FTT price and reverse-takeover status are from the April 29, 2005 acquisition and placing announcement. The May 2005 resolutions, the admission of 3,462,356 shares, the admission document date and FTT's 2004 turnover are from the May 23, 2005 announcement. The margin, the average per business and the dividend ratio are this site's arithmetic. I did not open the 2003 or 2005 admission documents themselves, so the 2003 issue price is not given.

Related questions

When did Judges Scientific list on AIM?

Twice, in effect. Its 2003 interim results say it was floated on AIM on January 7, 2003, after raising £2 million. In 2005 the FTT purchase was a reverse takeover under the AIM Rules, so the enlarged share capital was admitted again, with dealings expected from May 24, 2005. The group's 2025 results call this the 2005 re-admission, at 100p.

Does Judges Scientific publish what it pays for acquisitions?

Not as a multiple in the announcement I opened. It says it pays a disciplined multiple of earnings and gives no figure.
