Key Q&A

Q:Has anything changed meaningfully positive or negative on the customer programs or the demand outlook for this year?

A:We have not seen any material impact from tariffs, and hyperscalers have maintained their CapEx. However, we did see an impact from restrictions to China, which we have factored into our guidance.

Q:Can you walk us through the progression of scale up in your participation and set some timing?

A:Scale up presents a good opportunity for us, with significant contributions expected from PCIe scale-up networks and Scorpio X family shipments. We expect UAL to be a multibillion-dollar opportunity.

Q:Can you talk about the growth in Taurus and the diversity of the customer base?

A:We are shipping the 50-gig solution and have multiple designs at our lead customer, with plans to broaden our customer base.

Q:What are you seeing as the changes in the environment on the ASIC side versus the merchant GPU?

A:We are excited about the growing interest in Scorpio X family, which is becoming an anchor socket for AI racks.

Q:Could you describe if there's any differences to what you saw in the ramp of your revenue?

A:Our expectations have largely remained unchanged, and we are confident in our guidance.

Q:Are you seeing tightness in inference markets?

A:We benefit from both training and inference, and the complexity of rack-level systems is creating more opportunities.

Q:Can you elaborate on the Aries 6 upgrade cycle?

A:Aries 6 gearbox products are essential for matching protocol generations, and we have multiple engagements for these products.

Q:What is driving the inflection for custom racks?

A:The timing of custom racks varies, but many hyperscalers will customize to take advantage of their existing infrastructure.

Q:How do you think the market might shake out longer term, Ethernet versus UALink?

A:UALink is purpose-built for AI workloads, while Ethernet is widely deployed. We believe UAL will outperform Ethernet in performance.

Q:Is there any appreciable price difference between the X product and the P product?

A:The X-Series generally has a higher ASP due to its value in interconnecting GPUs.

Q:What are your thoughts on chips versus board-level solutions?

A:We aim to provide a rack-scale solution, and the form factors will depend on customer needs.

Q:Review of Unclear Management Responses

A:Management avoided giving a direct answer regarding the specific impact of China on sales, stating it was a 'modest impact' without providing exact figures. Additionally, there was a lack of clarity on the exact mix assumptions for custom racks going into the second half of the year, as it was described as 'constantly evolving'.
