TSEM is down 3.52% while momentum peers like MTSI and RMBS are up about 4.75% and 3.62%, respectively. This divergence versus rising peers points to a stock-specific reaction despite broader positive sector momentum.
Historical Context
| Date | Event | Sentiment | Move | Catalyst |
|---|---|---|---|---|
| May 04 | Investor conferences | Neutral | -1.4% | Participation in multiple investor conferences through May and June 2026. |
| Apr 27 | Defense SiGe products | Positive | +1.4% | Launch of high-power SiGe radar ICs for secure U.S. defense applications. |
| Apr 20 | Earnings timing | Neutral | -0.9% | Announcement of Q1 2026 results release date and conference call details. |
| Mar 25 | Japan fab expansion | Positive | +4.4% | Plan to expand 300mm Fab 7 capacity in Japan and restructure TPSCo. |
| Mar 25 | TPSCo restructuring | Positive | +4.4% | Strategic restructuring with Nuvoton, including ownership changes and $25M payment. |
Strategic manufacturing and restructuring announcements have previously aligned with positive single-day moves, while conference- and scheduling-related news has seen more muted or slightly negative reactions.
Over the last few months, TSEM has highlighted capacity expansion in Japan, strategic restructuring of TPSCo, defense-focused SiGe products, and upcoming investor conferences. The March 2026-03-25 restructuring and 300mm expansion headlines both coincided with about 4.38% gains, suggesting investors previously rewarded capacity and strategy updates. In contrast, neutral items like conference participation and earnings call timing in April–May 2026 saw modest negative to flat reactions. Today’s silicon photonics contracts and 2027–2028 targets build on that capacity- and photonics-focused narrative.
Market Pulse Summary
This announcement details substantial silicon photonics commitments, including $1.3 billion of 2027 contracted revenue and $290 million in prepayments, tied to a broader 2028 model of $2.8 billion revenue and $750 million net profit. It builds on recent filings that cite significant capex plans for SiPho and SiGe capacity and prior TPSCo restructuring steps. Investors may focus on execution of the global capacity ramp, customer concentration, and how quickly these contracts translate into sustained profitability.

2028 Contracts Demonstrate Substantially Higher Sipho Capacity Reservations
Customer Prepayments of
MIGDAL HAEMEK, Israel, May 13, 2026 - Tower Semiconductor (NASDAQ/TASE: TSEM), the leading foundry for high-value analog semiconductor solutions, today announced it has signed Silicon Photonics (SiPho) contracts for
The pre-paid capacity reservation is the customer contractual commitment, with their full demand and Tower shipment forecast being higher. The total 2027 customer demand is further augmented by healthy forecasts from the rich and broad SiPho customer base of over 50 active customers across wide-ranging SiPho based applications.
To support this accelerating demand, Tower is in the midst of substantial capacity ramp to expand its worldwide multi-fab SiPho capacity, the foundation to achieve the targeted model of
“These long-term agreements further strengthen Tower’s strategic position at the center of the rapidly expanding optical connectivity market,” said Russell Ellwanger, Chief Executive Officer of Tower Semiconductor. “These multi-year customer commitments underscore both the depth of our strategic partnerships and our customers’ strong confidence in Tower’s ability to execute on a differentiated, multi-generational silicon photonics technology roadmap addressing the accelerating performance demands driven by AI infrastructure growth. With our unique manufacturing scale, technology breadth, and expanding global capacity, we are well positioned to support the market across today’s high-volume pluggable optical transceivers as well as next-generation Near-Packaged Optics (NPO) and Co-Packaged Optics (CPO) solutions, enabling the continued scaling of data center bandwidth, power efficiency, and connectivity performance.”
Tower is enabling the explosive demand for AI, not only through aforementioned aggressive capacity expansion, but also through strategic investments in capabilities to enable next generation of Scale-out, Scale-across and Scale-up architectures for training and inference AI hardware. A subset of previously announced capabilities include: 400GHz/lane modulator and detector performance demonstrated both in our native SiPho platform as well as in heterogeneously integrated InP/SiPho and TFLN; SiPho based optical circuit switches for ultra-low latency all-optical networks; high-performance high-power DWDM lasers for “wide and slow” CPO architectures; and our hybrid-bonding capability for 3DIC integration.
Furthermore, Tower is actively engaged with key customers on the development of a variety of next-generation modulators, including TFLN, InP, and organic materials for ultra-high bandwidth, as well as Microring Modulators, Si-based Electro-Absorption modulators, and uLEDs for ultra-dense parallel data transmission. Most importantly, Tower continues to partner closely with the industry leading innovators to bring the best of Silicon Photonics technology to market for generations to come.
