Tower Semi (TSEM) is trading sharply higher after announcing a multi-year agreement with IQE to supply Indium Phosphide (InP) epiwafers used in optical connectivity products for AI-driven data center infrastructure. The deal supports TSEM's planned growth in silicon photonics, an area it has already identified as a key growth driver, while adding minimum purchase and supply commitments that improve visibility around execution. The agreement also resolves prior IP disputes between the companies through a broad royalty-free patent license, removing a legal overhang alongside the commercial agreement.
- Commercial relevance: IQE's InP epiwafers will be used across Tower's advanced silicon photonics platforms, including 200Gb/s-per-lane pluggable transceivers, next-generation 400Gb/s-per-lane modulators, and optical-circuit-switch applications for data centers, which are increasingly needed as AI data centers require faster and more power-efficient optical connectivity.
- Broader operating backdrop: TSEM's most recent update on May 13 already showed strong momentum, with Q1 revenue up 15% yr/yr to $414 mln and Q2 revenue guided to a company-record $455 mln. Management is also targeting sequential revenue and margin growth throughout 2026.
- Fits prior demand signals: The IQE agreement builds on TSEM's announced $1.3 bln of contracted 2027 SiPho revenue and $290 mln of customer prepayments for capacity reservations. TSEM also said 2028 contracts demonstrate substantially higher SiPho capacity reservations, and that full customer demand and shipment forecasts are higher than the initial prepaid commitments.
- Supply visibility: The agreement includes a minimum purchase commitment by TSEM in the first year, a reciprocal supply commitment from IQE, and minimum volume commitments thereafter, supporting execution in a capacity-sensitive growth area.
- What to watch: The IQE agreement supports the silicon photonics roadmap, but TSEM still needs to convert customer commitments, prepayments, and supply agreements into sustained revenue and margin growth, particularly with shares climbing sharply over the past year.

While many semiconductor and tech stocks are stronger today, TSEM's IQE agreement also builds on its silicon photonics momentum and AI data-center connectivity story. The deal supports the roadmap behind TSEM's $1.3 bln of contracted 2027 SiPho revenue and $290 mln of customer prepayments by adding supply visibility for advanced optical connectivity products. It also resolves prior IP disputes, making the agreement cleaner from both a commercial and strategic standpoint.The larger takeaway is that TSEM is adding supply-chain support behind a SiPho ramp already backed by customer commitments, prepayments, and capacity expansion plans. With shares climbing sharply over the past year, investors will still need to see those commitments and capacity investments translate into sustained revenue growth and margin expansion.
