SANTA CLARA, Calif., May 06, 2025 (GLOBE NEWSWIRE) -- Astera Labs, Inc. (NASDAQ:ALAB), a global leader in semiconductor-based connectivity solutions for cloud and AI infrastructure, today announced preliminary financial results for the first quarter of fiscal year 2025, ended March 31, 2025.

"Astera Labs started the year strong, with Q1 revenue growing 13% sequentially and 144% year-over-year, and exceeding our first quarter guidance for gross margin and earnings per share," said Jitendra Mohan, Astera Labs' Chief Executive Officer. "Our design wins across AI platforms, expanding portfolio with increasing value for customers, and significant traction with Scorpio fabric solutions strategically position us as a critical connectivity supplier for the entire AI rack. During the quarter, we saw strong demand for PCIe scale-up and Ethernet scale-out connectivity solutions in custom ASIC platforms, along with initial shipments for Scorpio P-Series and Aries 6 Retimers for merchant GPU-based platforms.

The modular design scales across different NVIDIA MGX configurations to accelerate time-to-market and deliver leading performance for next-generation AI systems. Scorpio-based solutions enable customers to maximize GPU productivity through enhanced data center observability, telemetry, and diagnostics using our COSMOS rack-scale management software.
• Ultra Accelerator Link™ (UALink™) Consortium announced the ratification of the UALink 200G 1.0 Specification which defines a low-latency, high-bandwidth interconnect for communication between accelerators and switches supporting up to 1,024 accelerators within an AI computing pod. As a board member and key contributor, Astera Labs proudly supports this new standard and is uniquely positioned to lead in this space by delivering a complete portfolio of connectivity solutions based on our deep expertise within scalable AI infrastructure.
• Expanded our Cloud-Scale Interop Lab to accelerate time-to-market of PCIe 6 AI platforms powered by Scorpio Smart Fabric Switches. Rigorous interoperability and performance testing of Scorpio P-Series Fabric Switches is accomplished with a wide range of PCIe 6.x exercisers, analyzers, GPUs, CPUs, NICs and SSDs across multiple PCIe generations and topologies. At the GTC 2025 show, we showcased the first end-to-end PCIe 6 interoperability with NVIDIA's Blackwell GPU and Micron's NVMe SSD with both our Aries 6 PCIe Smart Retimer and Scorpio-P PCIe Smart Fabric Switch. The expansion of our Cloud-Scale Interop Lab will enable customers to design with confidence, minimize interoperation risk, and reduce overall development time and costs.

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, non-GAAP net income, non-GAAP pro forma diluted earnings per share, and non-GAAP pro forma weighted-average share count. 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, non-GAAP net income, non-GAAP pro forma diluted earnings per share, and non-GAAP pro forma weighted-average share count 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 stock-based compensation expense, which is a non-cash 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.

Employer payroll taxes related to stock-based compensation resulting from our IPO

We exclude employer payroll taxes related to the time-based vesting and net settlement of restricted stock units in connection with our initial public offering (the "IPO"), because this does not correlate to the operation of our business. We believe that excluding this item provides meaningful supplemental information regarding operational performance given the amount of employer payroll tax-related items on employee stock transactions was immaterial prior to our IPO.

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.

Non-GAAP pro forma weighted-average shares to compute non-GAAP pro forma net income per share

We present non-GAAP pro forma weighted-average shares, assuming our redeemable convertible preferred stock is converted from the beginning of each respective periods presented, to provide meaningful supplemental information regarding EPS trend on a consistent basis. All of our outstanding redeemable preferred stock converted into the equivalent number of shares of common stock in connection with our IPO.
