Welsh semiconductor manufacturer IQE reports a 40% revenue increase amid warnings from CEO Jutta Meier regarding critical supply chain risks for indium phosphide caused by Chinese export controls.

Key Points

• IQE shares have surged 849% this year, driven by high demand for photonics chips used in AI data centers, smartphones, and defense technology.
• CEO Jutta Meier identified indium phosphide as a major industry bottleneck, noting that China currently controls 70% of the global supply.
• The company has raised its full-year growth guidance to over 30% despite ongoing geopolitical uncertainty surrounding export licensing.
• IQE plans to transition from the AIM to the Main Market of the London Stock Exchange to attract institutional capital and improve share liquidity.
• Export restrictions on raw materials are accelerating efforts by Western firms to seek alternative suppliers, though developing new capacity remains a multi-year challenge.

Why it Matters

The reliance on Chinese-controlled materials highlights a significant vulnerability in the European semiconductor supply chain that extends beyond chip design and fabrication. As companies like IQE attempt to hedge against geopolitical volatility, the industry faces a race to develop independent, long-term sources for essential raw materials to sustain the current AI infrastructure boom.
