Bernin (Grenoble), France, November 20^th, 2024 – Soitec (Euronext Paris), a world leader in designing and manufacturing innovative semiconductor materials, today announced its revenue for the second quarter of fiscal year 2025 and its half-year results of fiscal year 2025 (ended on September 30^th, 2024). The interim consolidated financial statements³ were approved by the Board of Directors during its meeting today.
Pierre Barnabé, Soitec’s CEO, commented: "As announced, after reaching the bottom in the first quarter, the rebound of second quarter revenue enabled the first half of the fiscal year to be in line with our expectations. Although sales continued to be impacted by the RF-SOI inventory correction, and the weak Automotive market, we have benefited from the increasing POI penetration and from the fast-growing data center market. The product portfolio diversification provided strong resilience of business strength and enabled the company to continue its growth in diversified end markets.

Despite lower revenue, our cash generation proved solid, allowing us to keep investing both in industrial capacity and in R&D to be ready to capture future growth, while maintaining a healthy balance sheet. We are confident in our ability to extend our rebound in the second part of our fiscal year, notably in the fourth quarter, as the situation of RF-SOI inventory level started to improve, allowing us to achieve our stable full-year revenue guidance together with around 35% EBITDA margin.

For calendar year 2025, we anticipate different dynamics across our three end markets, with Mobile Communications market expected to continue to slightly improve, Automotive & Industrial market weakness persisting through the first half of the year, and Cloud AI investments to remain at elevated levels.

Thereafter, our mid-term ambition to reach 2 billion dollars revenue will continue to be supported by the increasing adoption of engineered substrates, to deliver more powerful and energy-efficient solutions to a higher number of customers across our three end markets”, added Pierre Barnabé.

Second quarter FY’25 consolidated revenue

Soitec revenue reached 217 million Euros in Q2’25, down 11% on a reported basis compared with 245 million Euros achieved in Q2’24. This reflects a 9% year-on-year decline at constant exchange rates and perimeter⁴ and a negative currency impact of -2%. Decline in Mobile Communications, and to a lesser extent in Automotive & Industrial, was partially compensated for by a very strong performance in Edge & Cloud AI (previously named Smart Devices).

The expected rebound performed in Q2’25, with an 89% sequential organic growth, confirmed that Soitec reached the bottom of its cycle in Q1’25.

Mobile Communications

In Q2’25, Mobile Communications revenue reached 124 million Euros, down 25% year-on-year at constant exchange rates compared to Q2’24. It however increased by 76 million Euros against the 48 million Euros achieved in Q1’25, reflecting the progress in inventory correction at Soitec customers.

In the context of a recovering smartphone market, and progressive improvement in Soitec customers’ inventory absorption, volumes of RF-SOI wafers sales have picked up significantly from the weak Q1’25. They remained however much lower than in Q2'24, in line with the Group’s expectations. Soitec remains confident in further inventory absorption to take place in H2’25 and expects growth in RF-SOI sales to resume, supporting the Group’s full-year guidance.

On the other hand, sales of POI (Piezoelectric-on-Insulator) wafers dedicated to RF filters continued to grow sequentially, translating into a sharp year-on-year increase against Q2’24. POI activity benefits from a strong demand in China and from Soitec’s engagement with all leading US fabless companies. Soitec currently has ten active customers, and over ten more are in qualification phase.

Sales of FD-SOI wafers, designed to equip front end modules integrated in both 5G Sub-6 GHz and 5G mmWave smartphones, have picked up from the low level recorded in Q1’25, also showing growth against Q2’24.

Automotive & Industrial

Automotive & Industrial revenue reached 33 million Euros in Q2’25, down 11% year-on-year at constant exchange rates compared to Q2’24, reflecting the softness in the automotive market.

Power-SOI wafer sales increased as compared to the low level recorded in Q1’25 but were lower than Q2’24, driven by lower volumes in a context of the ongoing softness in the automotive market. Power-SOI remains a key component for gate drivers, in vehicle networking and increasingly Battery Management ICs, supported by an increasing number of foundries and IDMs worldwide.

In Q2’25, FD-SOI wafer sales, which continue to be mostly driven by adoption for automotive microcontrollers, radar and wireless connectivity, recorded another good performance, stable against Q1’25 and up compared to Q2’24.

Further SmartSiC^TM samples and prototypes were delivered during Q2’25, paving the way for device qualifications and wafer production ramp-up to gradually intensify, driven by customer demand.

Edge & Cloud AI

Edge & Cloud AI revenue reached 61 million Euros in Q2’25, up 66% at constant exchange rates compared to Q2’24, and up 38% on sequential basis compared to Q1’25.

Sales of FD-SOI wafers, which remain driven by the demand for Edge AI devices across consumer and industrial sectors, were above the level reached in Q2’24, capitalizing on the strong momentum in the build-up of the FD-SOI ecosystem across the industry.

Sales of Photonics-SOI wafers were particularly strong in Q2’25, much higher than in Q2’24 and Q1’25. 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 is now 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 Imager-SOI wafers for 3D imaging applications were higher than in Q2’24, benefitting from a low base effect.

H1’25 consolidated revenue

Consolidated revenue reached 338 million Euros in H1'25, down 16% on a reported basis compared to 401 million Euros in H1'24. This reflects a 15% decline at constant exchange rates and perimeter⁵, in line with Soitec’s guidance, and a slightly negative currency impact of -1%.

The decrease in revenue essentially reflects lower volumes in both RF-SOI and Power-SOI due to persisting inventory digestion across the smartphone value chain and a softer automotive market, partly offset by strong performance in POI, FD-SOI, Imager-SOI and Photonics-SOI. This strong performance from Soitec’s increasingly diversified product portfolio results in a more balanced revenue profile among the three end markets:

• Mobile Communications revenue reached 172 million Euros in H1'25, down 33% on a reported basis and down 32% at constant exchange rates compared to H1'24. Mobile communications represented 51% of total revenue against 64% in H1'24. This lower proportion notably derives from weaker RF-SOI volumes in connection with further inventory adjustment at customers, despite increasing penetration of 5G smartphones. RF-SOI performance was partly offset by a strong acceleration in POI wafer sales and, to a lesser extent, by slightly higher FD-SOI wafer sales.
  
  
• Automotive & Industrial revenue amounted to 59 million Euros in H1'25, down 21% on a reported basis and down 20% at constant exchange rates compared to H1'24. Automotive & Industrial represented 17% of total revenue against 19% in H1'24. This lower performance was essentially driven by a weak automotive market despite increasing adoption and higher content of Soitec’s products per vehicle.
  
  
• Edge & Cloud AI revenue reached 107 million Euros in H1'25, up 56% on a reported basis and up 57% at constant exchange rates compared to H1'24. Edge & Cloud AI represented 32% of total revenue against 17% in H1'24. This increase in revenue was driven by higher sales of Photonics-SOI wafers, which benefit from the rapidly growing needs of data centers to address the expansion of AI-related computing power capabilities, and by an uptick in Imager-SOI sales due to non-linear demand over the year.
  
  
  

EBITDA¹ margin² at a robust level

Consolidated income statement (part 1)

Mainly reflecting lower revenue, but also increased R&D investment, the current operating income went down from 85 million Euros in H1'24 to 28 million Euros in H1'25.

• Gross profit reached 101 million Euros, down from 144 million Euros in H1'24. Gross margin declined by 6 points to 30.0% of revenue. The weaker level of activity recorded in H1'25 resulted in a lower utilization of Soitec industrial capacity. In addition, depreciation costs were up, reflecting the Group’s current investment profile. These factors were partly offset by strong cost management, some agility in resource allocation between plants and higher subsidies.
  
  
• Net R&D expenses increased from 34 million Euros in H1'24 to 43 million Euros in H1'25 (12.6% of revenue). Gross R&D expenses before capitalization went up 19% to 77°million Euros, illustrating Soitec’s ambition to continue to invest in new products development, in the next generation of SOI products, in compound semiconductors (notably POI, SiC and GaN), as well as in the development of new engineered substrates. The lower proportion of capitalized R&D spending was more than offset by the recognition of higher R&D subsidies and higher prototype sales.
  
  
• Selling, general and administrative (SG&A) expenses amounted to 31 million Euros in H1'25 (9.2% of revenue) up from 25 million Euros in H1'24, essentially due to non-recurring positive effects in H1’24 and higher depreciation expenses.
  
  

The EBITDA^1,6 amounted to 113 million Euros in H1'25, down 15% from 132 million Euros in H1'24. EBITDA¹ margin² remained at a robust level, reaching 33.4%, 40 basis points above the level of 33.0% recorded in H1'24. The combination of a lesser absorption of fixed costs due to lower volumes and higher level of R&D investments, as evidenced by the lower current operating margin, was offset by higher non-cash items, notably depreciation costs.

Consolidated income statement (part 2)

Other operating expenses amounted to 4 million Euros in H1’25. They correspond to an impairment of Dolphin Design goodwill.

The net financial result came as an expense of 8 million Euros in H1'25 compared to an income of 2 million Euros in H1'24. Interest on cash investments and other financial income are almost stable at 10 million Euros, as are net financial expenses of 12 million Euros. The change in net financial result essentially reflects the difference between the net foreign exchange loss of 6 million Euros recorded in H1'25 and the foreign exchange gain of 3 million Euros recorded in H1’24.

The income tax expense amounted to 2 million Euros in H1'25 compared to 8 million Euros in H1'24. This reflects an effective tax rate of 12% compared to 9% in H1'24, the enforcement of the global minimum tax rule of 15% (Pillar 2) having an impact of around 1 point.

In line with the decline in operating income, the net profit amounted to 14 million in H1'25.
Solid Free Cash Flow generation after constantly high investments

Consolidated cash-flows

The Group generated a positive Free Cash Flow of 35 million Euros in H1'25, which represents an improvement of 120 million Euros compared to the 85 million Euros negative Free Cash Flow recorded in H1'24. Despite a lower EBITDA^1,6, this strong increase essentially comes as a result of a much-improved change in working capital in H1’25, while capital expenditure was maintained at a high level to support the Group’s current expansion.

The cash inflow from working capital amounted to 27 million Euros in H1'25, compared to a 69 million Euros cash outflow in H1'24. This is essentially reflecting:

• a strong 130 million Euros decrease in trade receivables, explained by the seasonality of sales with a particularly high level of activity recorded in the fourth quarter of FY’24; decrease was even higher than in H1'24 (106 million Euros),
  • the favorable impact of subsidies cashed in during the period.

These were partially offset by:

• a seasonal 65 million Euros increase in inventories built to fuel the expected rebound in the second part of the fiscal year (similar level of increase as in the first half of FY’24),
  • a 48 million Euros decrease in trade payables (compared to a 105 million Euros decrease in H1'24 which included non-recurring downpayments in connection with the signing of new long-term supply agreements).

The net cash used in investing activities amounted to 94 million Euros in H1'25, compared to 129 million Euros in H1'24. It takes into account the 10 million Euros positive impact of financial income from cash investment (8 million Euros in H1'24). Including production equipment under leases (17 million Euros in H1'25), total cash out related to capital expenditure amounted to 120 million Euros, slightly below the 138 million Euros spent in H1'24. Capital expenditure was essentially related to industrial investments, including:

• the ongoing phase 1 of Singapore 300-mm facility extension,
• additional POI and SmartSiC^TM manufacturing tools.

Capital expenditure also included investments supporting the Group’s environmental policy, as well as IT investments.

Net cash used in financing activities amounted to 44 million Euros in H1'25 essentially reflecting a net decrease in borrowings and related interest paid.

In total, including a 4 million Euros negative impact of exchange rate fluctuations (2 million Euros positive impact in H1'24), the net cash outflow was moderate, reaching 13 million Euros in H1'25 (127 million Euros in H1’24) resulting in a steady strong cash position of 696 million Euros on September 30^th, 2024.

Strong balance sheet maintained

Soitec maintained a strong balance sheet as of September 30^th, 2024.

Shareholders’ equity stood at 1.5 billion Euros on September 30^th, 2024. It was stable compared to March 31^st, 2024.

Following the sale of Dolphin Design IP activities finalized in October 2024, and the signing of Dolphin ASIC activities in November 2024, the assets and liabilities of Dolphin Design activities have been classified in the Group’s balance sheet as assets held for sales for 65 million Euros and liabilities associated with assets held for sale for 33 million Euros as of September 30^th, 2024.

Financial debt on September 30^th, 2024, was also stable at 747 million Euros compared to 6 months before. The 49 million Euros net increase in leasing debt was mainly offset by a total of 39°million Euros of debt repayments as well as the 16 million Euros impact of the classification of Dolphin Design liabilities as liabilities associated with assets held for sale. Taking into account the 13 million Euros cash outflow recorded in H1'25, the net debt position⁷ was kept at a moderate level up from 39 million Euros on March 31^st, 2024, to 51 million Euros on September 30^th, 2024.

FY’25 revenue and EBITDA outlook confirmed, capex revised slightly down

Soitec confirms anticipating revenue to rebound in the second half of FY’25, driven by the ongoing recovery of the RF-SOI activity following the progressive end of the inventory correction among customers. Besides, Soitec will continue to benefit from the strong structural demand for Photonics-SOI and FD-SOI and the continued adoption of POI. Consequently, Soitec confirms anticipating a stable year-on-year revenue in FY’25.

Soitec also confirms expecting FY’25 EBITDA¹ margin² to be around 35%

Expected annual capital expenditure has been revised slightly down, at around 230 million Euros, against 250 million Euros initially planned, to reflect slower end market dynamics.

Q2’25 key events

Soitec kicks off European project to develop future high-frequency semiconductors

On September 10^th, 2024, a European research and industry consortium led by Soitec began work to develop a future generation of high-frequency semiconductors based on Indium Phosphide (InP). These technologies are set to address applications ranging from photonics for mega data centers and AI to radio frequency front-ends and integrated antennas critical for 6G mobile communication, Sub-THz radar sensing and beyond. Indium phosphide (InP) devices can operate at frequencies approaching or exceeding 1 terahertz (THz), offering superior speeds and increased energy-efficiency compared to silicon technologies.
