Risk or Challenges
Intel Fab 11X Agreement: Intel has expressed its intention not to perform under the September '23 Fab 11X agreement. This could disrupt operations and customer commitments as flows are being redirected to the Japanese Fab 7.
Utilization Rates: Fab 2 operated at 60% utilization, Fab 5 at 75%, and Fab 9 at 65%, which are below the model full utilization of 85%. This underutilization could impact operational efficiency and profitability.
CapEx Investment: The company announced an additional $270 million CapEx investment on top of the previously announced $650 million. This significant expenditure could strain financial resources if demand projections are not met.
Tax Regulation Changes: The implementation of Pillar 2 regulation will increase the effective tax rate to at least 15% in all manufacturing sites, potentially impacting net profitability.
RF Mobile Revenue Decline: RF mobile revenue declined by 15% year-over-year, influenced by a shift from 200mm to 300mm nodes and reduced exposure to lower-margin offerings. This could affect revenue stability in this segment.
Mixed Signal CMOS and Discrete Revenue Decline: Mixed Signal CMOS and Discrete revenues decreased by 18% and 14% year-over-year, respectively, as part of a strategy to focus on higher-margin platforms. This could lead to short-term revenue challenges.
Customer Prepayment Dependency: Over 70% of the total SiPho capacity is either presently reserved or in the process of being reserved through 2028, backed by customer prepayment. Dependency on these prepayments could pose risks if customer commitments falter.
Currency Fluctuations: While hedging strategies are in place, fluctuations in the Japanese yen and Israeli shekel could still have limited but notable impacts on margins.

Key Q&A
Q:What does the increased collaboration with NVIDIA imply?
A:The collaboration involves the output parameters of photonics, TIA, drivers, pluggable, copper, or optical cable. It focuses on alignments and supply needs through module customers and commitments on supply shipments.
Q:Does the 5x capacity increase for silicon photonics and silicon germanium include incremental demand from NVIDIA and partners?
A:Yes, it refers to total demand and the actual capacity being built. By Q4 2026, the silicon wafer capacity will be 5x the amount shipped in Q4 2025.
Q:Can the company help prospective customers with high voltage requirements for AI server racks requiring 800-volt DC?
A:The company has 800-volt capabilities in fabs but not in ICs. They do have higher voltage IC capabilities with and without SOI.
Q:Is the company shipping directly to NVIDIA?
A:No, the company ships through resellers and module makers or integrators. They do not ship photonics directly to NVIDIA.
Q:Is the company working on R&D for CPUs or end-to-end offerings?
A:The company is not directly packaging CPUs but is working on multiple architectures of CPO and collaborating with XPU makers on CPO strategies.
Q:Can the rollout of additional CapEx be completed sooner than the end of 2026?
A:The capacity qualification ramp will happen throughout the year, with most tools arriving by mid-Q3 2026. Full qualification is targeted by December 2026, but delays of 1-3 months are possible.
Q:What are the expectations for silicon photonics contribution in 2026 and 2027?
A:The demand is solid, and the ramp profile depends on operational execution. Some technical work and customer qualifications are still required, but the company is confident in meeting its targets.
Q:Are there concerns about memory shortages or increased prices affecting the mobile business?
A:Yes, there are concerns as these factors are beyond the company's control. They work closely with customers to plan and have alternatives to backfill capacity if needed.
Q:Is the 2028 financial model based on a run rate or full year?
A:The model targets achieving the financial goals within 2028, either by run rate or full year.
Q:Will the CapEx investments bring fabs to full utilization?
A:No, silicon photonics alone will not bring fabs to full utilization. However, other flows like RFSOI, power, and imaging are fungible and contribute to utilization.
Q:What was the dollar amount for the one-time tax benefit in Q4?
A:The one-time tax benefit was approximately $10 million.
Q:What did the company get for the $105 million lease extension?
A:The company secured an additional 3.5 years of lease for the Newport Beach facility, extending it to the end of 2030.
Q:Did the change in U.S. depreciation rules affect the company's model?
A:No, the change in U.S. depreciation rules had no impact on the company's model.
Q:Review of Unclear Management Responses
A:Management avoided providing specific details about projects or activities with NVIDIA beyond what was stated in the press release. Additionally, there was some vagueness in discussing the exact timeline for achieving full capacity qualification and the potential impact of memory shortages on the mobile business.
