Q1 2026 and Recent Business Highlights

Announced Scorpio X-Series 320-lane Smart Fabric Switch, the largest open, memory-semantic fabric switch, purpose-built for frontier AI lab workloads. The AI fabric switch leverages open and platform specific protocols to deliver infrastructure optionality across diverse accelerators in high-radix scale-up topologies. New capabilities like Hypercast™ and In-Network Compute boost collective operations by up to 2x, reduce latency, and improve token economics for agentic inference workloads. Scorpio X-Series 320-lane is shipping today with expected production ramp in the second half of 2026 targeting the merchant scale-up market projected to reach $20 billion by 2030.
Expanded market-leading Scorpio P-Series PCIe-6 Fabric Switch family that now spans from 32 to 320 lane configurations for flexible switch deployment at any scale. With customer-optimized firmware and COSMOS embedded software, infrastructure fleet management is bolstered with non-disruptive updates and comprehensive in-depth signal, link, and packet diagnostics using a common interface across Astera Labs' complete connectivity portfolio. Shipments to multiple customers across several Scorpio P-Series variants are expected in the second half of this year with broader volume ramps targeted for 2027.
Collaborated with the Ultra Accelerator Link Consortium to publish a new UALink 2.0 specification which introduces additional features and capabilities while maintaining its foundational memory-semantic model. UALink 2.0 enhancements include supporting In-Network Compute for greater efficiency, confidential computing for tighter security and multi-path routing for improved resiliency. UALink 2.0 delivers these advances while maintaining an open, vendor-neutral ecosystem to provide a purpose-built AI compute fabric capable of scaling with industry needs over time.
Showcased portfolio of AI connectivity solutions at NVIDIA GTC 2026 highlighting the broad market opportunity for intelligent networking across a wide variety of merchant-GPU platforms and applications. Astera Labs' connectivity portfolio supports merchant GPU platforms by offering Scorpio P-Series PCIe Smart Fabric Switches and Aries 6 PCIe Smart Retimers for customized scale-out networking, Leo CXL memory controllers to accelerate KV Cache, Taurus SCMs for Ethernet scale-out switches, and custom solutions for NVLink Fusion scale-up connectivity.

Discussion of Non-GAAP Financial Measures

We use certain non-GAAP financial measures, including those concerning our financial outlook, to supplement the performance measures in our consolidated financial statements, which are presented in accordance with GAAP. A reconciliation of these non-GAAP measures to the closest GAAP measure can be found later in this release. The timing and impact of any adjustments to arrive at the corresponding GAAP financial measures concerning our financial outlook are inherently dependent on future events that are typically uncertain or that may be outside of our control. These non-GAAP financial measures include non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income, non-GAAP operating margin, non-GAAP tax rate, and non-GAAP net income. We use these non-GAAP financial measures for financial and operational decision-making and as a means to assist us in evaluating period-to-period comparisons. By excluding certain items that may not be indicative of our recurring core operating results, we believe that, non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income, non-GAAP operating margin, non-GAAP tax rate, and non-GAAP net income provide meaningful supplemental information regarding our performance. Accordingly, we believe these non-GAAP financial measures are useful to investors and others because they allow for additional information with respect to financial measures used by management in its financial and operational decision-making and they may be used by our institutional investors and the analyst community to help them analyze the health of our business. However, there are a number of limitations related to the use of non-GAAP financial measures, and these non-GAAP measures should be considered in addition to, not as a substitute for or in isolation from, our financial results prepared in accordance with GAAP. Other companies, including companies in our industry, may calculate these non-GAAP financial measures differently or not at all, which reduces their usefulness as comparative measures.

We adjust the following items from one or more of our non-GAAP financial measures:

Stock-based compensation expense

We exclude non-cash stock-based compensation expense from certain of our non-GAAP financial measures because we believe that excluding this item provides meaningful supplemental information regarding operational performance. In particular, companies calculate non-cash stock-based compensation expense using a variety of valuation methodologies and subjective assumptions. Moreover, stock-based compensation expense is a non-cash charge that can vary significantly from period to period for reasons that are unrelated to our core operating performance, and therefore excluding this item provides investors and other users of our financial information with information that allows meaningful comparisons of our business performance across periods.

Acquisition-related costs

We exclude acquisition-related costs incurred in connection with our acquisitions, which we generally would have not otherwise incurred in the periods presented as part of our continuing operations. Acquisition-related costs include certain incremental expenses incurred to effect a business combination such as third-party costs: advisory, legal, accounting, valuation, and other professional fees. We believe that providing the non-GAAP measures excluding these costs assists our investors because such costs are not reflective of our ongoing operating results.

Income tax effect

This represents the impact of the non-GAAP adjustments on an after-tax basis and one-off discrete tax adjustments that are unrelated to our core operating performance in connection with the presentation of non-GAAP net income and non-GAAP net income per diluted share. This approach is designed to enhance investors' ability to understand the impact of our non-GAAP tax expense on our current operations, provide improved modeling accuracy, and substantially reduce fluctuations caused by GAAP to non-GAAP adjustments.
