Filtronic Full-Year Results: Profits Retreat as Investment Sets Up FY2027 Growth

Filtronic's full-year results tell two contrasting stories. Reported revenue was broadly stable, but profits fell sharply as the radio-frequency technology specialist invested in people, products and manufacturing capacity.

Look beyond the immediate earnings decline, however, and there are signs that Filtronic PLC is building a broader and potentially more scalable business. New space and defence contracts have reduced its dependence on its largest customer, while the order book already covers approximately 90% of current market expectations for FY2027 revenue.

The central question for investors is whether those investments can translate into stronger revenue and profit growth from here.

Filtronic's key FY2026 figures

Financial measure	FY2026	FY2025	Change
Revenue	£55.5 million	£56.3 million	Down 1%
Adjusted EBITDA	£11.3 million	£17.0 million	Down 34%
Operating profit	£4.0 million	£13.4 million	Down 70%
Profit before tax	£3.8 million	£13.4 million	Down 72%
Basic earnings per share	2.07p	6.42p	Down 68%
Cash at bank	£12.9 million	£14.5 million	Down 11%
Net cash	£7.3 million	£10.8 million	Down 33%
Operating cash generation	£11.8 million	£13.8 million	Down 15%

Adjusted EBITDA means earnings before interest, tax, depreciation, amortisation, share-based payments and exceptional items. It is intended to show underlying operating performance before several accounting and non-cash charges.

No dividend has been proposed for FY2026, unchanged from the previous year.

Why did Filtronic's profits fall?

Headline revenue slipped only marginally from £56.3 million to £55.5 million. Management said that underlying organic sales increased by 6% to £59.7 million before two specific headwinds.

The first was a £3.5 million non-cash charge against revenue relating to the SpaceX share warrant agreement, up from £1.3 million in FY2025. The warrants are accounted for as consideration payable to a customer, effectively operating like a deferred volume rebate.

The second was a £2.0 million currency headwind from the weaker US dollar. A significant proportion of Filtronic's revenue is denominated in dollars, meaning each dollar of sales translated into fewer pounds.

Profitability also came under pressure from a deliberate pricing strategy designed to secure higher production volumes and from investment in the organisation. Operating costs increased by 19% to £25.1 million, with total headcount rising from 186 to 236.

Engineering numbers increased from 72 to 92, while manufacturing headcount rose from 89 to 109. Research and development spending reached £9.3 million, compared with £6.7 million the previous year.

This was not an accidental cost overrun. Filtronic is choosing to spend ahead of expected demand. Even so, investors will want evidence that the higher cost base can produce stronger revenue and margins in future periods.

Customer diversification is a meaningful positive

Filtronic's relationship with SpaceX remains strategically important. During the year, the company secured a $62.5 million contract, equivalent to £47.3 million, covering the deployment of next-generation gallium nitride E-band products.

Gallium nitride, or GaN, is a semiconductor material suited to high-power and high-frequency applications. The contract represents Filtronic's largest single order to date and moves the technology from development towards volume production.

The concentration risk has not disappeared, but it is reducing. Revenue from Filtronic's largest customer fell to 68% of group revenue from 83% in FY2025. Management said this reflected the addition of new programmes and customers rather than a reduction in its engagement with the lead customer.

Other wins included:

• An $8.0 million development contract with a US-based customer for high-performance amplifier systems.
• A further post-year-end contract from the same US customer for a high-frequency transmit and receive module.
• A €7.0 million multi-year agreement with a European space customer.
• A £13.4 million contract with a leading European defence prime contractor.

Revenue from aerospace and defence increased by 135%, while critical communications revenue rose by 28%. Space revenue declined by 12%, despite increased volumes, because of currency movements, the warrant charge and pricing decisions.

This diversification matters. A wider customer base should make Filtronic less exposed to the spending decisions or programme timing of any single organisation. However, two customers still represented 78% of FY2026 revenue, so concentration remains an important risk.

Investment is creating substantial capacity

Capital expenditure increased from £4.0 million to £10.3 million, mainly reflecting the completion of Filtronic's new Sedgefield headquarters and manufacturing facility, automated testing equipment and additional production lines.

Management says the facility can support annual revenue above £200 million. That figure describes production capacity, not a revenue forecast, but it shows the scale of the company's ambition.

The investment consumed cash, with net investing outflows of £12.6 million exceeding the £11.8 million generated from operations. Cash at bank consequently declined to £12.9 million.

The balance sheet nevertheless remains in a net cash position. Filtronic also has an undrawn £10.0 million revolving credit facility, increased from £5.0 million in January 2026. This gives management additional financial flexibility if working-capital or investment requirements increase.

For another example of a UK engineering business balancing near-term performance with growth expectations, see how Senior PLC upgraded its full-year outlook following a strong first half.

What to expect in FY2027

Filtronic entered FY2027 with a record order book covering approximately 90% of current market expectations for full-year revenue. The actual market forecast figure was not disclosed.

The board expects FY2027 trading to be weighted towards the second half. This reflects the transition from gallium arsenide supply to the ramp-up of next-generation GaN production.

That phasing creates execution risk. Production must scale as planned, customer programmes need to remain on schedule and the company must manage a larger number of concurrent contracts. Any delay could have a disproportionate effect when so much revenue and profitability is expected later in the year.

Currency exposure is another consideration, given the importance of US dollar revenue. Filtronic uses hedging contracts where future cash flows are considered highly probable, but exchange-rate movements can still affect reported results.

Investors should also monitor the potential dilution from the SpaceX warrant arrangements. The original agreement gives SpaceX the right to acquire up to 21.7 million shares at 33.0p, while a second arrangement covers up to 10.9 million shares at 92.8p, subject to relevant conditions.

The order book now needs to deliver

FY2026 was a weaker year for reported earnings, and the scale of the decline should not be overlooked. Operating profit fell by 70%, basic earnings per share dropped to 2.07p and no dividend is being paid.

The more encouraging part of the story is what Filtronic has built around those results. The company has secured major multi-year contracts, reduced its largest customer's revenue share, expanded into higher-value GaN technology and created manufacturing capacity well beyond its current sales level.

Management remains confident of meeting FY2027 market expectations, supported by substantial order-book coverage. The next test is converting that visibility into revenue while recovering profitability from a much larger operating cost base.
