SOITEC REPORTS FY’25 THIRD QUARTER REVENUE

SOITEC REPORTS FY’25 THIRD QUARTER REVENUE

• Reaching €226m, Q3’25 revenue was almost stable vs. Q2’25 and down 10% at constant exchange rates and perimeter compared with Q3’24
• 9M’25 revenue reached €564m, down 12% on a reported basis and decreased by 13% at constant exchange rates and perimeter vs. 9M’24
• FY’25 guidance revised: revenue expected to decrease by high single digit year-on-year at constant exchange rates and perimeter (compared to flat previously), and EBITDA¹ margin² expected between 32% and 34% (compared to around 35% previously)
• Given the current lack of visibility on end markets, Soitec expects at this stage quite limited growth for FY’26

Bernin (Grenoble), France, February 5^th, 2025 – Soitec (Euronext Paris), a world leader in designing and manufacturing innovative semiconductor materials, today announced consolidated revenue of 226 million Euros for the third quarter of FY’25 (ended December 29^th, 2024), down 6% on a reported basis compared to the third quarter of FY’24. This reflects a 10% decline at constant exchange rates and perimeter, a positive currency impact of 5% and a negative scope effect³ of 1%.

Pierre Barnabé, Soitec’s CEO, commented: “After a very strong sequential rebound in the second quarter, we maintained the third-quarter revenue at a fairly similar level. The good performance of the Mobile Communications division was driven by sustained momentum in POI, and a seasonal tailwind in RF-SOI sales. Despite seasonal restocking in the second half of the fiscal year, the customers continue to optimize RF-SOI inventory levels based on seasonality and market conditions, which will keep driving fluctuations over the next few quarters. At the same time, we are strengthening our position as a leader, notably with the introduction of new innovative 300mm products. The Automotive and Industrial division continues to be impacted by a weak automotive market. In Edge & Cloud AI, the momentum remains strong, supported by significant investments in cloud infrastructure across the industry to accelerate AI computing power, as well as increasing demand at the edge for lower energy consumption and processing costs.

Due to worsening conditions in the Automotive and Consumer markets, a couple of customers have requested to put some delivery requests on hold. As a consequence, we are adjusting our guidance for fiscal year 2025, with annual revenue expected to decrease by high single digit year-on-year. We are managing our EBITDA margin to be between 32% and 34%.

With the lack of visibility on our end markets for now, it is also too early to provide specific guidance for fiscal year 2026. Given current market conditions, we expect at this stage quite limited growth for fiscal year 2026.

Our fundamentals remain solid and will allow us to accelerate as end markets recover. We continue to enhance our technology leadership, to strengthen our SOI positioning with both existing and new customers, and to deploy our expansion into compound semiconductors with the acceleration of POI volumes and a fifth customer in qualification on SmartSiC^TM.”

Third quarter FY’25 consolidated revenue (unaudited)

Q3’25 revenue reached 226 million Euros. After the sharp sequential increase achieved in Q2’25, it was up 4% versus Q2’25 on a reported basis (down 2% at constant exchange rates and perimeter). Compared to Q3’24, it was down 10% at constant exchange rates and perimeter.

Q3’25 revenue reflected an improved performance in Mobile Communications and a weaker performance in Automotive & Industrial as well as in Edge & Cloud AI which was due to a different phasing in Imager-SOI wafer sales.

Mobile Communications

Mobile Communications revenue reached 154 million Euros in Q3’25, up 11% at constant exchange rates and perimeter compared to Q3’24. In the context of a healthier smartphone market and inventory situation, Mobile Communications revenue continued to recover in Q3’25 after the sharp rebound already experienced in Q2’25.

As expected, growth in RF-SOI wafer sales has resumed. Q3’25 sales were significantly higher than in Q2’25, and also higher than in Q3’24. While reflecting different situations, inventories in the overall supply chain now seem to progressively normalize. Soitec is confident that growth in RF-SOI wafer sales will continue in Q4’25. Soitec continues to reinforce its strong customer intimacy, leveraging state-of-the-art Innovation capabilities to develop leading-edge products, as evidenced by the announcement of its commitment to provide GlobalFoundries with its latest generation of RF-SOI 300mm wafers to support GF’s most advanced 9SW platform.

Sales of POI (Piezoelectric-on-Insulator) wafers dedicated to RF filters continue to grow quarter after quarter, as the adoption of Surface Acoustic Wave (SAW) filters on POI is accelerating with ten active customers in production, and more than ten in qualification. Q3’25 POI wafer sales were significantly higher than in Q2’25 and Q3’24. Soitec is engaged with all leading US fabless companies.

Sales of FD-SOI wafers, the only solution for fully integrated 5G mmWave system-on-chip, have made further progress in Q3’25, showing an increase from Q2’25 as well as growth compared to Q3’24.

Automotive & Industrial

Automotive & Industrial revenue reached 25 million Euros in Q3’25, lower than in Q2’25 and down 47% at constant exchange rates and perimeter compared Q3’24, reflecting the ongoing difficulties of the automotive market.

Power-SOI wafer sales reached a particularly low level in Q3’25, as the ongoing weakness of the automotive market is leading to some inventory adjustments at customer level. Power-SOI remains a key component for gate drivers, in vehicle networking and in Battery Management ICs.

Conversely, FD-SOI wafers recorded a better level of sales in Q3’25 than in Q3’24. Automotive FD-SOI continue to be mostly driven by adoption for microcontrollers, radar and wireless connectivity, delivering on superior performance and power efficiency.

Further SmartSiC^TM samples and prototypes were delivered during Q3’25, paving the way for new qualifications. Soitec has engaged with a fifth customer in a qualification process. The current weakness of the automotive market and the longer than initially anticipated customers’ qualification cycles confirm a delay in the expected wafer production ramp-up, as stated earlier this year.

Edge & Cloud AI

Edge & Cloud AI revenue reached 47 million Euros in Q3’25, down 30% at constant exchange rates and perimeter compared to Q3’24. Performance was however contrasted from one product to another.

Demand in Photonics-SOI wafers continue to benefit from a very positive momentum driven by high investments in Cloud infrastructure. Sales of Photonics-SOI were much stronger in Q3’25 than in Q2’25, and significantly higher than in Q3’24. This reflects the need for more powerful and more energy-efficient data centers to support the exponential growth of AI-related computing power capabilities. Photonics-SOI has become a standard technology platform for high-speed and high bandwidth optical interconnections in data centers, adopted in pluggable optical transceivers, and used for the development of Co-Packaged Optics.

Sales of FD-SOI wafers remained as strong as in Q2’25 but were lower than in Q3’24. FD-SOI technology is a key enabler for AI-driven consumer and industrial IoT applications due to its unique power efficiency, performance, thermal management and reliability advantages.

Sales of Imager-SOI wafers for 3D imaging applications are down year-on-year, reflecting the phase out of this product.

First nine months FY’25 consolidated revenue (unaudited)

Consolidated revenue reached 564 million Euros in 9M’25, down 13% at constant exchange rates and perimeter compared to 641 million Euros in 9M’24.

Overall, the decrease in Soitec’s 9M’25 revenue essentially reflects lower volumes in both RF-SOI and Power-SOI wafers, partly offset by strong performances in POI, Photonics-SOI and Imager-SOI wafers.

Mobile Communications revenue reached 326 million Euros in 9M’25 (58% of total revenue), down 18% at constant exchange rates and perimeter compared to 9M’24, with significant improvement quarter after quarter over FY’25.

Automotive & Industrial revenue amounted to 84 million Euros in 9M’25 (15% of total revenue), down 31% at constant exchange rates and perimeter compared to 9M’24, reflecting the current weakness of the automotive market.

Edge & Cloud AI revenue reached 154 million Euros in 9M’25 (27% of total revenue), up 16% at constant exchange rates and perimeter compared to 9M’24, supported by strong growth of photonics SOI products.

FY’25 outlook

Soitec expects FY’25 revenue to be down high single digit year on year, at constant exchange rates and perimeter (compared to flat revenue previously) as a couple of customers requested to put some deliveries on hold on the back of worsening conditions in the Automotive and Consumer markets. This implies strong sequential growth in Q4’25, primarily driven by the continued recovery in RF-SOI wafer sales supported by some seasonal restocking. Additionally, Soitec will continue to benefit from strong demand for Photonics-SOI products and the growing adoption of POI.

Soitec is managing FY’25 EBITDA¹ margin² to be between 32% and 34%.

FY’26 outlook

With the lack of visibility on our end markets for now, it is too early to provide specific guidance for fiscal year 2026. Given current market conditions, Soitec expects at this stage quite limited growth for fiscal year 2026.
