- Filtronic was quoted at 440p, up 7.06%, in delayed Hargreaves Lansdown data, outpacing a 0.20% rise in the FTSE AIM 100.
- A late-Monday RNS showed David and Monique Newlands cut their combined voting-rights position to 7.98% from 8.978%.
- The stock’s rise keeps pressure on valuation after Berenberg lifted its target price to 360p in April, still below Tuesday’s quoted price.
Filtronic shares rose sharply in Tuesday trading, extending a steep run in the AIM-listed radio-frequency specialist as investors continued to price in growth from space and defence contracts. Delayed Hargreaves Lansdown data showed the shares at 440p, up 7.06%, while the FTSE AIM 100 was up just 0.20%.
The move matters now because Filtronic is trading close to a much larger market value than the small-cap tag investors once attached to it. Hargreaves Lansdown put its market capitalisation at about £962 million, with volume above 4.2 million shares and a previous close of 411p.
There was no fresh contract announcement on Tuesday morning. The latest regulatory filing, released late Monday, showed David and Monique Newlands reduced their total holding to 7.98%, including 7.70% in direct voting rights and 0.28% through a spread bet, a derivative wager that gives economic exposure without owning the shares outright.
Filtronic makes advanced radio-frequency, or RF, equipment for space, aerospace and defence, telecoms infrastructure and critical communications. RF refers to technology that sends, receives or conditions radio signals, the kind needed in satellite links, defence sensors and high-capacity wireless networks.
The company’s first-half results in February showed why the stock has drawn more attention. Revenue for the six months to Nov. 30 was £25.3 million, broadly flat on £25.6 million a year earlier, while adjusted EBITDA — earnings before interest, tax, depreciation and amortisation, a measure of operating profit before some non-cash costs — fell to £5.1 million from £8.7 million as the group invested in people, facilities and product development.
The order book carried the story. Filtronic said it had entered the second half with record order cover, including its largest-ever SpaceX contract, valued at $62.5 million, a €7.0 million European space customer contract and a £13.4 million contract with a European defence prime. About 90% of FY2026 revenue was covered by contracted orders, the company said.
Chief Executive Nat Edington said in the February statement that demand across space, aerospace and defence “remains robust” and that the company had entered the second half “confident of continuing our planned growth.” Investegate
Broker interest has helped, though it also sharpens the valuation debate. Berenberg raised its target price on Filtronic to 360p from 213p on April 28 after a site visit, saying the company remained “one of the best-positioned pure-play space names” in the UK market, but Tuesday’s quote was already above that upgraded target.

Cavendish director of research Edward Stacey said after a March $8 million U.S. contract win that the award underpinned forecasts and showed progress in Filtronic’s GaN strategy. GaN, or gallium nitride, is a semiconductor material used in high-power amplifiers; Stacey said the company was “positioned for strong revenue growth in FY27E and over the next 3–5 years.” Edison director Katherine Thompson said the same contract added diversification in satellite communications and could lead to more orders depending on development work.

The share move also came in a firmer UK tape. Reuters reported the FTSE 100 up 0.61% and the FTSE 250 up 0.81% late Tuesday morning after softer labour data eased worries about an immediate Bank of England rate increase.
Among nearby AIM defence and electronics names, Cohort rose 3.68%, Concurrent Technologies gained 3.29% and Gooch & Housego added 2.27%, according to Hargreaves Lansdown’s FTSE AIM 100 table. Filtronic’s larger gain suggests the market was still treating it as a more direct space-and-satellite growth trade, not just another beneficiary of the broader small-cap lift.
The risk is that expectations have moved faster than earnings. Profit fell in the first half as costs rose, the company cited weaker U.S. dollar revenue exposure, and management said reducing customer concentration remains a strategic priority. If a major programme slips, order conversion slows, or investors start to compare the share price more closely with broker targets, Tuesday’s rally could look stretched rather than simply deserved.
