Key Q&A
Q:You said that the incremental $300 million was already considered in your $2.77 billion total revenue expectations long term. Is that right?
A:Yes, it is included. It may mean achieving the target earlier than expected.
Q:If no incremental upside, then what's the accelerated pace you expect? What's the give and take of that extra CapEx?
A:Acceleration of achievement towards the $500 million net profit run rate, enabling higher profit sooner.
Q:Can you talk about some of the applications driving the aggressive growth in RF infrastructure?
A:The need for build-out, especially AI-driven, with high volumes of 400 gigabit per second, 800 gigabit per second, and 1.6 gigabit platforms. Currently, 30% of starts are dedicated to the 1.6 gigabit platform.
Q:Who do you see as your main competitors in silicon photonics, and are you considering raising prices given the supply-demand imbalance?
A:Competitors exist but breaking into Tower's position is difficult. Tower is not opportunistic with pricing despite tight demand, focusing on long-term partnerships. They are targeting a Q4 SiPho revenue shipment run rate of over $320 million and plan to triple capacity by the second half of 2026.
Q:Do you see any changes in competitive dynamics in silicon photonics?
A:Competitors are trying to take market share, but Tower's strong customer relationships and advanced platforms make it difficult for others to break in.
Q:You mentioned the shift to silicon photonics is permanent. Can you explain what you mean by that?
A:Silicon photonics is cost-effective and offers performance benefits compared to EML, making it a long-term solution for 400, 800, and 1.6T applications.
Q:What kind of mix do you expect to have of 1.6 versus slower speeds in your business next year?
A:Currently, 1.6T is close to 1/3 of starts and is expected to exceed 50% within the first multiple quarters of next year.
Q:What is the time frame to reach full utilization of the 3x capacity increase in silicon photonics?
A:Full installation is expected by the first half of 2026, with full start capability in the second half. Revenue from increased capacity may begin in the second half of 2026.
Q:How do you think about gross margin fall through in the next few quarters, considering silicon photonics as a margin-accretive business?
A:Gross profit in Q3 was 24%. Incremental margin is usually 50%, offset by Newport Beach lease costs and depreciation from additional CapEx. Total additional CapEx is $600 million over 15 years, with a gradual ramp to $10 million per quarter.
Q:Are you baking in increased content opportunities with transceivers, particularly on the receive side?
A:Yes, there is an opportunity to increase volumes with advanced platforms for 300-millimeter receive SiPho, starting in Q4 and expanding in 2026.
Q:How will the SiPho capacity increase by 3x be split into increased content versus units of transceivers shipped?
A:The 3x capacity increase is mostly for transmit, with little receive included currently.
Q:Would you need to increase capacity again as customers migrate to receive SiGe with SiPho?
A:Yes, additional capacity would be needed, and Tower is proactive in addressing this potential demand.
Q:What is the update on R&D for packaging to extend the addressable market?
A:Tower is working with a leading packaging house on CPO and NPO capabilities, including through silicon via and advanced modulation for future generations like 51.2T.
Q:Where are we with 3.2T technology, and is there a risk of needing an entirely new technology?
A:No new technology is needed. Issues like DSP are being addressed, and Tower is working on 400G modulation pathways to support 3.2T.
Q:Is the revenue from SiPho totally gated by capacity?
A:Yes, demand is there if capacity is available.
Q:When will you start reporting Agrate utilization?
A:Reporting could start anytime, as the first ramp is currently underway.
Q:How do you think about acquiring more 300-millimeter capacity for silicon photonics?
A:Tower is focused on organic growth rather than partnerships and will provide more details in the Q4 release.
Q:Review of Unclear Management Responses
A:Management avoided directly addressing the timeline for achieving full 3x shipment capacity in 2026, stating it depends on customer demand and PO sizes. They also did not provide a clear breakdown of how increased SiPho capacity would be split between transmit and receive applications.
