Key Q&A
Q:Could you give a little more detail on what segments you expect to contribute and maybe rank order them for your sequential growth through the second half of the year?
A:The biggest contributor is infrastructure, particularly Silicon Germanium (SiGe) and Silicon Photonics (SiPho). SiPho revenue is expected to double in 2025 compared to 2024. Power management is expected to remain strong, and imaging is seeing over a 20% increase in run rate due to machine vision. RFSOI for mobile is rebounding with a strong increase from Q1 to Q2 and an even stronger increase expected in Q3.
Q:Would you consider yourself now fully booked through the end of the year? And if so, do you have any available capacity to support any near-term turns business that could provide any upside to your estimate?
A:There is room for immediate upsides, particularly in Fab 2 and San Antonio Fab 9, which are focused on SiGe and SiPho capacity. The company has a strong worldwide manufacturing footprint and cross-qualifies flows across factories, allowing flexibility to meet customer demands. Immediate-term business is being seen, especially in the Tonami Fab 5 in Japan.
Q:Can you provide more details about supporting transmit and receive functions in Silicon Photonics and the expected growth in content over the next couple of years?
A:The company is innovatively addressing a specific receive function in SiPho, which could add about 20% to the served market. SiPho shipments are expected to double by the end of 2026 compared to Q4 2024 levels. The company is also working on 3.2T capabilities requiring new materials for 400 Gbps modulators.
Q:To what degree is the improvement in RF mobile space cyclical or related to inventory replenishment and/or share gains?
A:The 20% growth in Q2 over Q1 and the 30% targeted growth in Q3 over Q2 are related to inventory consumption from a strong 2024 and share gains by customers. Some growth in Q3 and Q4 is due to increased forecasts and purchase orders from an existing customer.
Q:How do you see your customers evolving in the transition from copper to pluggable and eventually to co-package optics, and how does this impact your capacity planning?
A:Pluggables remain the mainstay, with a shift from EML to SiPho solutions due to cost and performance benefits. SiPho adoption is growing, especially at 1.6T, and is expected to be stronger at higher speeds. Capacity planning aligns with customer demand, with significant growth expected in SiPho and SiGe.
Q:How does integrating the modulator into your process technology help with incremental revenue per wafer?
A:Integrating the modulator into the SiPho process technology simplifies production and reduces costs compared to indium phosphide alternatives. This integration is a key driver for SiPho adoption and incremental revenue.
Q:Do you think RF mobile and infrastructure will come in pretty much the same for the year, or can mobile even beat that?
A:Infrastructure will be substantially bigger than RF mobile, as it includes both SiGe and SiPho products. However, RF mobile is experiencing high run rates similar to past years.
Q:Why has RF mobile come back so much? Is it specific customers or the market?
A:The rebound is due to a combination of customers gaining market share and inventory correction from a strong 2024. Most inventory has been consumed, leading to increased demand.
Q:Should we expect other income to continue increasing?
A:No, the baseline for other income is around $10.6 million per quarter. The recent increase to $14.4 million was due to a specific gain and is not expected to continue.
Q:How is the company tracking towards its revenue and margin goals set in the third quarter of 2023?
A:The company is outperforming on margin expectations and is targeting $2.7 billion in revenue by 2028-2029.
Q:How should we think about depreciation growth and free cash flow given the strong CapEx investment?
A:Depreciation is expected to remain around $70-$75 million per quarter. Free cash flow is currently neutral due to high CapEx but is expected to improve as revenue grows.
Q:Should we assume OpEx in 2025 will trend flat to up on a year-over-year basis?
A:Yes, OpEx is expected to remain flat at around $40 million per quarter.
Q:What are the plans for the company's cash beyond funding CapEx?
A:The company plans to use cash primarily for CapEx growth, which is seen as the best return for shareholders.
Q:Review of Unclear Management Responses
A:Management avoided providing specific details about the transition from copper to pluggable optics and the exact percentage of SiPho versus EML adoption. Additionally, they did not clarify the drivers behind a customer's increased forecast and purchase orders in Q3 and Q4.
