Key Q&A
Q:How has the transition to more inferencing-based workloads, especially agentic-based workloads, created new opportunities for the team and potentially expanded the SAM opportunity?
A:Inferencing has created significant opportunities in the industry. Astera has been focused on AI applications from the start, supporting both training and inferencing workloads. The KV Cache offload is a key part of AI inferencing, and the newly introduced Scorpio X 320 lane family supports in-network compute and hypercast, reducing networking overhead and improving performance. Additionally, the COSMOS software enables diagnostics, telemetry, and performance improvements for inferencing workloads.
Q:Can you provide details on the Scorpio ramp and its impact on revenue?
A:The Scorpio product family has been a major growth driver, with Scorpio P ramping due to scale-out opportunities and Scorpio X ramping for scale-up connectivity. Scorpio is expected to become the largest product line by the end of the year, surpassing last year's 15% of total revenue. X-Series revenue is expected to exceed P-Series revenue as the year progresses.
Q:What is the time frame for optical scale-up becoming more relevant, and what is required to transition from copper to optical?
A:Astera has been preparing for optical opportunities, with foundational technologies and the aiXscale acquisition. Near-Package Optics (NPO) opportunities are expected to ramp in 2027, with pluggable connector technologies for CPO scaling out in 2027 and mainstream deployments in 2028. The company is working on supply chain commitments to ensure readiness for these transitions.
Q:What is the growth potential of the Leo product line and its impact on memory and CXL demand?
A:There is increased traction for CXL in general-purpose compute and AI inferencing. The Leo product line is on track for deployment with Microsoft Azure's M-Series instances, expected to reach general availability by the end of the year. Astera has also secured a second design win for a custom CXL application, expected to ship for revenue in 2027.
Q:How should we think about the mix between Aries and Scorpio products in 2027?
A:While Scorpio is expected to be the largest and fastest-growing product line, Aries is also expected to see strong growth due to its PCIe 6 portfolio. Both product lines are significant drivers of growth.
Q:Will Scorpio X and Scorpio P switches continue to increase lane counts as clusters grow larger?
A:Astera is heavily investing in AI fabric switches, including current and upcoming generations. Lane counts and radix are determined in close collaboration with customers to meet deployment profiles. Future switches will support both copper and optical connectivity, including NPO and CPO.
Q:What is the NVLink Fusion opportunity for Astera, and how does it fit into the competitive landscape?
A:Astera is developing NVLink Fusion devices for hybrid rack situations, collaborating with NVIDIA and a hyperscaler. The project is progressing well, with revenue expected in 2027. Astera focuses on real customer applications and remains undistracted by competitive press releases.
Q:How should we think about ASPs for higher radix Scorpio switches?
A:ASPs for larger switches are higher, driven by features like in-network compute and hypercast. Astera expects over $1,000 worth of content per accelerator, with continued growth as optical-enabled switches are introduced.
Q:Can you provide details on the KV Cache offload custom design and its potential revenue impact?
A:KV Cache offload is a significant opportunity for AI inferencing. While exact dollar figures are not finalized, the ASP is expected to be meaningful, reflecting the value of the memory and controllers.
Q:What is Astera's approach to Near-Package Optics (NPO) and CPO, and how does XPO fit into the strategy?
A:Astera focuses on NPO and CPO, with NPO providing high egress density and CPO expected to ship in 2027. While XPO is a newer technology, Astera will engage with customers interested in it but remains focused on NPO and CPO.
Q:How does Astera balance standard and custom products in its portfolio?
A:Astera offers software-defined architectures for customization through standard products like Aries and Scorpio. Custom solutions are pursued systematically, focusing on opportunities with manageable risks and margins.
Q:What is the adoption process and expected timeline for UALink-based switches?
A:UALink-based switches are expected to launch in 2027, aligning with announcements from Amazon and AMD. These switches will offer higher complexity, speed, and media attach options, including copper, NPO, and CPO, providing a larger TAM opportunity.
Q:Does Astera have sufficient capacity to meet revenue growth expectations?
A:Astera has sufficient supply in place through the end of the year and is working with supply chain partners to ensure capacity for 2027. Inventory levels are adequate to meet revenue commitments.
Q:Review of Unclear Management Responses
A:Management avoided providing specific dollar figures or detailed metrics for certain opportunities, such as the KV Cache offload custom design and its revenue impact. Additionally, while discussing ASPs for Scorpio switches and UALink-based switches, management used general terms without offering precise data or clear comparisons.
