Scorpio Becomes the Largest Product Family in a Record Quarter

Astera Labs (NASDAQ:ALAB) reported third quarter fiscal 2026 results on November 3, 2026 for the quarter ended September 30. Revenue of USD 584.9 million was up 49% sequentially and 154% year over year. Simple arithmetic on those growth rates implies about USD 393 million in the prior quarter and about USD 230 million a year earlier. The company said Scorpio fabric switches became its largest product family, led by Volume production of the Scorpio X-Series 320-lane switch. Astera Labs makes semiconductor-based connectivity products for rack-scale AI infrastructure, linking accelerators, memory and networks inside data centers.

GAAP Versus Non-GAAP: Where the 44.7% Margin Comes From

GAAP Operating Income was USD 179.1 million, a 30.6% margin, while non-GAAP operating income was USD 261.6 million, a 44.7% margin. The roughly USD 82 million gap (own arithmetic) comes from items the company excludes, chiefly stock-based compensation, acquisition-related costs and Fair Value adjustments on Equity investments. GAAP gross margin was 72.3% against 72.4% non-GAAP, so the difference sits mostly in operating expenses. GAAP net income was USD 182.9 million, or USD 0.99 per diluted share, against non-GAAP net income of USD 243.4 million, or USD 1.32. The extract of the release does not include a balance sheet, so cash is not stated here.

Guidance, New Products and the Risks Behind a Steep Ramp

For the fourth quarter the company guides revenue to USD 730 million to USD 750 million, a midpoint about 26% above the third quarter (own arithmetic). It expects a GAAP gross margin near 72%, GAAP operating expenses of USD 273 million to USD 279 million, and non-GAAP diluted EPS of USD 1.62 to USD 1.66 on about 187 million shares. Product milestones include Aries 7 sampling in the fourth quarter of 2026 and Orion rack designs through partners from the first quarter of 2027. Risks include the timing of customer deployments, the pace of PCIe and UALink adoption, competition and the dependence of Demand on AI infrastructure spending. The release mentions a Warrant agreement with Amazon and collaborations with AMD, Intel and NVIDIA without giving financial terms.

Where Things Stand

Revenue grew this quickly because Scorpio switches moved into high-volume production on top of existing Aries and Leo products, and management says design wins are widening across customers. Astera Labs (NASDAQ:ALAB) is guiding to another sequential step-up, though growth from a record base depends on a small number of large AI deployments, and the release does not break out customer concentration. The gap between GAAP and non-GAAP profit is also large, so investors comparing earnings should note the basis. The next checkpoints are Aries 7 sampling this quarter and the first Orion availability in early 2027.
