IQE (LSE:IQE) has entered into a multi-year supply agreement with Tower Semiconductor to provide indium phosphide (InP) epiwafers for advanced silicon photonics applications used in next-generation data centre infrastructure.
The agreement supports the development and deployment of high-speed optical connectivity technologies designed for artificial intelligence and hyperscale computing environments. The supplied materials will be used in silicon photonics platforms enabling 200Gbs and 400Gb optical solutions, including pluggable transceivers and optical circuit switching technologies.
The contract includes minimum supply and purchase commitments, providing greater visibility for both companies as demand for high-performance optical networking solutions continues to grow.
Partnership Targets Expanding AI Data Centre Market
The collaboration positions IQE within a rapidly growing segment of the semiconductor market, where increasing AI workloads are driving demand for faster and more efficient data transmission technologies.
Management believes the agreement strengthens IQE’s exposure to Tier 1 hyperscale cloud operators and AI infrastructure providers, while supporting the broader adoption of silicon photonics in advanced data centre architectures.
For Tower Semiconductor, the arrangement secures access to a reliable source of specialised semiconductor materials required for its photonics manufacturing roadmap.
Intellectual Property Dispute Resolved
Alongside the commercial agreement, the companies have reached a separate intellectual property settlement that resolves all existing disputes between the parties.
Under the terms of the accord, IQE has been granted a worldwide, royalty-free licence to Tower Semiconductor’s porous silicon patent portfolio. The agreement brings an end to all related litigation and removes a source of uncertainty that had previously existed between the two companies.
Management said the resolution allows both parties to focus on expanding their commercial relationship and pursuing future growth opportunities in the photonics market.
Strategic Benefits Extend Beyond Supply Agreement
The combined supply and licensing arrangements are expected to strengthen IQE’s position in advanced optical communications, a market benefiting from rising investment in AI infrastructure and cloud computing.
By securing long-term customer commitments while resolving intellectual property issues, the company believes it is better positioned to capitalise on growing demand for high-performance semiconductor materials.
Financial Challenges Remain a Consideration
Despite the strategic significance of the agreement, IQE continues to face financial headwinds. The company remains affected by ongoing losses, negative gross profit reported in 2025 and continuing free cash flow pressure.
Rising debt levels and lower shareholder equity have also weighed on the investment case. However, technical indicators have improved, with the share price trading above key moving averages and positive momentum signals suggesting stronger market sentiment.
Valuation remains difficult to assess given the company’s negative earnings profile and the absence of a dividend programme.
