Windar Photonics Reports 18% Revenue Growth and Strong H1 2025 Performance

Windar Photonics H1 2025: 18% revenue growth, bigger pipeline, and a busier H2 ahead

Windar Photonics has posted an upbeat set of unaudited interim results for the six months to 30 June 2025. Revenue rose 18% to €2.7 million as demand for its LiDAR-based turbine optimisation and the Nexus software suite broadened across regions and platforms. The business remains loss-making, but management points to a heavy H2 delivery schedule, a stronger order book, and a step-up in capacity to meet it.

If you are new to the story, Windar sells WindEye and WindTimizer LiDAR sensors (laser-based wind measurement), plus the Nexus OS software that optimises blade pitch and yaw to squeeze out more power and reduce wear. The next leg is monitoring – a Nexus TPM (Turbine Performance Monitoring) module due to launch in Q4 2025.

Key numbers at a glance

Metric	H1 2025	H1 2024	Change
Revenue	€2.72 million	€2.30 million	+18%
Gross profit	€1.68 million	€1.39 million	Up €0.29 million
Gross margin	Not disclosed precisely	Not disclosed precisely	+2 percentage points vs H1 2024
EBITDA loss (before warrant/share-based payments)	€0.2 million	€0.1 million	Wider, due to higher marketing spend
Loss after tax	€0.73 million	€0.30 million	Wider
Basic loss per share	0.8 cents per share	0.4 cents per share	Wider
Cash at 30 June 2025	€6.03 million	€2.76 million	Stronger

Further helpful markers: orders scheduled for delivery in H2 2025 stood at €3.6 million as of August 2025, and sales plus orders already equal 138% of 2024 revenue by the end of August.

Operational momentum: more turbines, more regions, more capacity

The commercial story is moving beyond a single niche. Windar says its optimisation solution now controls more than 20% of all installed Vestas V82 turbines in North America as at June, with a large new order signed in August expected to push this beyond 25% when installed in Q3 2025. That is a meaningful beachhead in a well-understood platform.

Testing is underway on a much wider set of turbines, including GE and Senvion in North America and a direct test on a major Goldwind wind farm in China. Early Chinese test results showed “substantial” potential power gains, which the company hopes to convert into a major order. That matters because it points to a broader addressable market and reduced single-platform risk.

Execution capacity has been addressed too. Windar moved into new manufacturing facilities in Copenhagen at the end of June, giving the company the potential to quintuple production. New VP hires for the Americas and Europe should help turn pipeline into purchase orders.

Software shift: higher-margin, recurring revenue on the horizon

Gross margin improved by 2 percentage points versus H1 2024, helped by the first software revenues. Software is attractive because once a client has LiDAR and Nexus OS installed, new features can be added as licence-based modules. The big near-term addition is the Nexus TPM module in Q4 2025, focused on high-precision turbine efficiency monitoring and performance analytics.

In plain English, optimisation boosts output by adjusting the turbine in real time, while TPM should prove whether a turbine is truly performing to spec over its life. If adoption goes to plan, recurring software income could both smooth revenue and lift margins over time.

Costs, FX and tariffs: what’s going on under the bonnet

EBITDA (earnings before interest, tax, depreciation and amortisation) remained in the red at a €0.2 million loss, mainly because management leaned into marketing to drive growth. At the operating level the group posted a €0.49 million loss from operations and a €0.73 million loss after tax.

Two external factors bit in H1. First, currency headwinds: a €0.5 million loss from FX, with roughly half linked to December’s fundraise proceeds being held in sterling and the rest from the US dollar and renminbi dropping 8-9% versus the euro. Second, North American import tariffs briefly slowed customer decisions, though the August US$2.6 million order shows normal service resuming.

Management also notes cost of goods sold at period end was 15% lower than at the end of 2024, which should help offset FX impacts in the coming periods. Cash of €6.0 million gives headroom to keep investing in growth.

Why these results matter for FY25 and beyond

There are two big takeaways. One, demand is broadening – across geographies and turbine platforms – with tangible orders and tests rather than just talk. Two, Windar is quietly building an installed base that can be monetised with software modules, potentially improving gross margins and visibility.

On the flip side, the company is still loss-making, and H2 is doing the heavy lifting for FY25. Working capital is lumpy, finance expenses rose, and currency exposure remains a swing factor. The concentration in V82s is improving but not yet fully diversified.

What could move the share price next

• Conversion of the Chinese Goldwind test into a “major order”.
• Further wins beyond V82s – especially GE and Senvion platforms in North America.
• Smooth delivery of the August US$2.6 million order under the new tariff and tax-credit regime.
• Launch and early uptake of the Nexus TPM module in Q4 2025.
• Evidence that gross margin continues to improve as software scales.

My take: cautiously positive with clear milestones to watch

This reads like a business moving from pilot wins to platform penetration. The 18% revenue growth and stronger order coverage for H2 underpin guidance that Windar is “well placed” to meet market expectations. The expanded factory and beefed-up sales team suggest management is planning for a bigger 2026 as well.

Risks remain – chiefly FX, delivery execution in a second-half weighted year, and the need to convert tests to firm orders. But cash is solid, costs per unit are improving, and the shift to licence-based software is the right strategic move for returns.

Bottom line

Windar Photonics’ H1 2025 shows growing demand, improving margins, and a clearer route to recurring software income. It is not profitable yet, but the order book, new US contract, and pending TPM launch give the second half plenty of catalysts. Delivery now needs to do the talking.
