• Record quarterly revenue of $65.3 million driven by expanding AI infrastructure build-out, up 29% QoQ and up 269% YoY
• Sampling third generation Aries Smart DSP Retimers for PCIe 6.x connectivity to leading AI platform providers to support next-generation cloud infrastructure

SANTA CLARA, Calif. — (BUSINESS WIRE) — May 7, 2024 — Astera Labs (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 2024, ended March 31, 2024.

“Astera Labs started the year strong, achieving record revenue in the first quarter, driven by the accelerating deployment of AI infrastructure,” said Jitendra Mohan, Astera Labs’ Chief Executive Officer. “As hyperscalers embark on a significant transformation of their data centers to support AI applications with increased capital investment, we're witnessing the emergence of a multi-year growth cycle. Our Intelligent Connectivity Platform, comprising of the COSMOS software suite and semiconductor-based PCIe, Ethernet, and CXL solutions, is uniquely positioned to support this growth and is foundational to deploying AI infrastructure at scale. In the first quarter, we further extended our connectivity platform and started sampling our third generation of Aries Retimers with support for PCIe 6.x and the industry’s first PCIe/CXL Smart Cable Modules for Active Electrical Cable applications to enable multi-rack GPU clustering.”

Discussion of Non-GAAP Financial Measures

We use certain non-GAAP financial measures to supplement the performance measures in our consolidated financial statements, which are presented in accordance with GAAP. These non-GAAP financial measures include non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income (loss) and 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 income (loss), non-GAAP net income (loss), pro forma non-GAAP diluted earnings (loss) per share, and pro forma non-GAAP 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 certain forward-looking non-GAAP financial measures as the GAAP measures are not accessible on a forward-looking basis. 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 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 comparison 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 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, and 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.

Tax effect

This amount is used to present each of the adjustments described above on an after-tax basis 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 its current operations, provide improved modeling accuracy, and substantially reduce fluctuations caused by GAAP to non-GAAP adjustments.

Pro-forma non-GAAP weighted-average shares to compute non-GAAP net income (loss)

We present pro-forma non-GAAP weighted-average shares, assuming the 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.
