ALAB Astera Labs Inc

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 fourth quarter and full fiscal year 2024, ended December 31, 2024.

“Astera Labs delivered strong Q4 results, with revenue growing 25% versus the previous quarter, and capped off a stellar 2024 with 242% revenue growth year-over-year,” said Jitendra Mohan, Astera Labs’ Chief Executive Officer. “The revenue growth in 2024 was largely driven by Aries PCIe Retimer products, with Taurus Smart Cable Modules for Ethernet coming in strongly in Q4. We expect 2025 to be a breakout year as we enter a new phase of growth driven by revenue from all four of our product families to support a diverse set of customers and platforms. This includes our flagship Scorpio Fabric products for head-node PCIe connectivity and backend AI accelerator scale-up clustering.”

Full Year Fiscal 2024 Business Highlights

• Introduced new portfolio of Scorpio Smart Fabric Switches purpose-built for AI infrastructure at cloud-scale. The Scorpio Smart Fabric Switch family features two application-specific product lines with a multi-generational roadmap, including the P-Series for GPU-to-CPU/NIC/SSD PCIe Gen 6 connectivity and the X-Series for platform-specific, back-end AI accelerator clustering. Scorpio is currently shipping in pre-production quantities.
• Joined the Ultra Accelerator Link Consortium as a promoting member on the Board of Directors. UALink technology will be used to enable efficient high-speed scale-up connectivity between AI accelerators within large and growing cluster sizes for AI workloads. Astera Labs is well positioned to quickly contribute to this new and compelling industry initiative to develop and advance UALink technology.
• Demonstrated the industry’s first end-to-end PCIe optical connectivity link to provide extended reach for larger, disaggregated GPU clusters. PCIe over optics expands Astera Labs’ widely deployed and field-tested Aries family of Smart DSP retimers and Smart Cable Modules (SCMs) to deliver robust PCIe and CXL connectivity in chip-to-chip, box-to-box, and rack-to-rack topologies throughout the data center.
• Expanded the widely deployed and field-tested Aries PCIe/CXL Smart DSP Retimer portfolio with the introduction and initial shipment of Aries 6 Retimers, the industry’s lowest power PCIe 6.x/CXL 3.x Retimer solution, to achieve higher bandwidth and extended reach across complex AI and compute topologies.
• Shipped Aries PCIe/CXL Smart Cable Modules for Active Electrical Cable applications to enable multi-rack GPU clustering and low-latency memory fabric connectivity within AI infrastructure. The solution drives seven meters of reach over flexible copper cables to seamlessly and affordably interconnect clusters of GPUs across rack enclosures.
• Showcased the first public demonstration of end-to-end interoperability between a PCIe 6.x Switch and a PCIe 6.x SSD at DesignCon 2025. The PCIe 6.x link-up was between an Astera Labs Scorpio P-Series Fabric Switch and Micron’s PCIe 6.x SSDs and showcased remarkable sequential read speeds exceeding 26GB/s.

Discussion of Non-GAAP Financial MeasuresWe use certain non-GAAP financial measures 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. These non-GAAP financial measures include non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income (loss), non-GAAP operating margin, non-GAAP tax rate, non-GAAP net income (loss), non-GAAP diluted earnings (loss) per share, and non-GAAP 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 (loss), non-GAAP operating margin, non-GAAP tax rate, non-GAAP net income (loss), non-GAAP pro forma diluted earnings (loss) 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.

No reconciliation is provided with respect to the forward-looking non-GAAP financial measures included in our non-GAAP financial outlook, as the GAAP measures are not accessible on a forward-looking basis. As a result, we cannot reliably predict all necessary components or their impact to reconcile such financial measures without unreasonable effort. The events necessitating a non-GAAP adjustment are inherently unpredictable and may have a significant impact on our future GAAP financial results.

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 effectThis 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 (loss) and non-GAAP net income (loss) 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 (loss) 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.

It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor(s) may cause actual results or outcomes to differ materially from those contained in any forward-looking statements we may make. Accordingly, you should not rely on any of the forward-looking statements. Astera Labs disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law.
