Soitec Performance Under Pressure, But Photonics SOI Outlook Positive

Overview

This report focuses on Soitec's upcoming financial results and conference calls for fiscal years 2025 and 2026. It anticipates that the company's profits for FY2025-2026 will face pressure due to capacity utilization declines and FX headwinds, while noting that its Photonics SOI business may see positive updates. The report states that although the stock price has already risen by 619%, investors should remain cautious during the newly appointed CEO's first earnings call, while considering opportunities to add positions during pullbacks.

Core views

The report expects significant margin compression for Soitec in FY2025-2026, driven primarily by two factors: approx. 600 basis points impact from lower capacity utilization in H2 FY2025, and approx. 300 basis points drag from FX pressures. Its estimated EBITDA is EUR 138 million, corresponding to margins of approx. 24%. This is below consensus but may align with adjustments. For FY2026 Q4 (F4Q26), the company guided for approx. 20% sequential revenue growth, but expects FY2027 Q1 (F1Q27) revenue to decline approx. 45% sequentially, mainly due to seasonality in Mobile Communications. Furthermore, the report deems the earnings call key, especially regarding Photonics SOI performance. While the company maintains a 20-30% TAM growth forecast, given LightCounting's latest industry forecast, this figure could rise. However, management prefers qualitative rather than quantitative updates to avoid over-promising and missing targets.

Analysis framework

The institution adopts a combined approach using financial data and industry trends for analysis. First, assess the company's current profitability and cost structure through historical revenue and profit data, identifying key drivers of margin decline (declining capacity utilization, FX impact). Secondly, starting from an industry perspective, analyze the market prospects of the Photonics SOI business, combining third-party agency (e.g., LightCounting) forecasts to judge whether the company's growth expectations are reasonable. Finally, combining management's statements on market outlook, judge whether the company will communicate actively on the business during the earnings call to enhance investor confidence. The entire analysis process reflects a balanced consideration of short-term earnings pressure and long-term growth potential.
