Record quarterly revenue of $230.6 million, up 20% QoQ and 104% YoY Strong Q3 revenue growth driven by new AI platform ramps featuring multiple product familiesScorpio fabric switch design wins expand to several platforms at multiple hyperscaler customers SAN JOSE, Calif., Nov. 04, 2025 (GLOBE NEWSWIRE) -- Astera Labs, Inc. (Nasdaq: ALAB), a leader in semiconductor-based connectivity solutions for rack-scale AI infrastructure, today announced preliminary financial results for the third quarter of fiscal year 2025, ended September 30, 2025. “Astera Labs delivered strong financial results in Q3 with revenue growing by 20% sequentially to a new record level of $230.6 million,” said Jitendra Mohan, Astera Labs’ Chief Executive Officer. “During the quarter, we saw robust demand and upside across our signal conditioning, smart cable module (SCM), and switch fabric portfolios as new AI platforms ramped up production. Looking into Q4, we anticipate continued PCIe 6 momentum alongside robust growth from our Taurus Ethernet SCMs. We remain focused on our rack-scale vision, which is further strengthened by the proposed acquisition of aiXscale Photonics, which we believe will support our customers' technology roadmaps and increase our market reach beyond copper interconnects.” Third Quarter 2025 Financial Highlights GAAP Financial Results: Revenue of $230.6 million, up 20% sequentially and up 104% year-over-yearGAAP gross margin of 76.2%GAAP operating income of $55.4 millionGAAP operating margin of 24.0%GAAP net income of $91.1 millionGAAP diluted earnings per share of $0.50 Non-GAAP Financial Results (excluding the impact of stock-based compensation expense and the income tax effects of non-GAAP adjustments): Non-GAAP gross margin of 76.4%Non-GAAP operating income of $96.1 millionNon-GAAP operating margin of 41.7%Non-GAAP net income of $88.2 millionNon-GAAP diluted earnings per share of $0.49 Q3 2025 and Recent Business Highlights Entered into a definitive agreement to acquire aiXscale Photonics GmbH, a provider of fiber-chip coupling technologies. The evolution to AI Infrastructure 2.0 demands scale-up connectivity solutions that meet aggressive speed, power, reach, and reliability requirements while facilitating high-volume, rack-scale integration. Optical connectivity will be critical to supporting the massive bandwidth needs of scale-up systems with hundreds of accelerators. The acquisition will help enable Astera Labs to develop photonic scale-up solutions by combining aiXscale’s fiber-chip coupling capabilities with Astera Labs’ connectivity and signal processing expertise.Showcased our AI rack-scale vision with a full portfolio of purpose-built connectivity solutions at the 2025 Open Compute Project (OCP) Global Summit built across a multitude of open standards including PCIe, UALink, Ethernet, CXL, and OpenBMC. Live demos highlighted state-of-the-art silicon, hardware, and software solutions enabling an open and collaborative ecosystem for optimizing rack-scale performance and flexibility. Our experts also delivered six technical sessions on topics including UALink deployment strategies and PCIe security.Announced new comprehensive collaborations spanning GPU, CPU, cables, connectors, ODMs, IP design and verification, and software management providers to accelerate AI Infrastructure 2.0 deployment through open standards.

The webcast will be recorded and available for replay on the company’s website for the next six months. Discussion of Non-GAAP Financial MeasuresWe 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 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 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.
