Chip interconnect specialist Astera Labs has reported a spectacular third quarter, with revenue surging 154 per cent as demand for high-speed data centre connections accelerates.
The company posted record sales of $584.9 million for the three months ending 30 September 2026, up 49 per cent from the previous quarter. Apparently, connecting thousands of increasingly expensive processors has become a rather lucrative occupation.
GAAP net income reached $182.9 million, with operating income of $179.1 million and a gross margin of 72.3 per cent. Non-GAAP net income came in at $243.4 million, while diluted earnings per share reached $1.32, comfortably illustrating how much money can be extracted from the bits of silicon that keep other chips talking.
Astera’s Scorpio fabric switches were the biggest contributors to growth, becoming the company’s largest product family by revenue. The Scorpio X-Series 320-lane switches have entered high-volume production, helping manufacturers connect large numbers of processors and accelerators without turning their expensive computing installations into elaborate traffic jams.
Astera Labs chief executive Jitendra Mohan said: “Astera Labs delivered outstanding Q3 2026 results, with record quarterly revenue of $584.9 million, up 49 per cent sequentially and up 154 per cent year-over-year, with broad-based growth led by Scorpio, which ramped to high-volume production and became our largest product family by revenue.”
The company claims it is expanding beyond conventional PCIe connectivity into memory expansion, optical communications and complete rack-scale computing architectures. This lets it sell more components for each accelerator installed, increasing revenue without having to manufacture the processors itself.
Its recently announced Aries 7 family supports PCIe 7 signal conditioning across copper and optical connections. The technology includes retimers, redrivers and optical components designed to maintain signal integrity across everything from centimetres of circuit-board traces to optical links extending more than 50 metres. Initial customer sampling is expected during the fourth quarter.
Astera has introduced its Orion rack-scale reference architecture, which supports configurations containing between eight and 160 accelerators per pod. The design lets customers choose their preferred CPUs and GPUs, potentially avoiding the vendor dependency that makes purchasing departments reach for the emergency whisky.
The Orion platform combines Scorpio switching technology with memory connectivity and management software. Astera expects OEM and ODM partners to begin offering reference and system designs during the first quarter of 2027, targeting companies building large-scale computing infrastructure.
Memory connectivity is becoming another significant opportunity. Astera’s expanded Leo controller family supports PCIe 6 and CXL 3.2, allowing processors to access additional DDR4 and DDR5 memory. The company claims its latest controllers can double memory bandwidth and capacity compared with the previous generation.
Its Leo X-Series can provide memory access across accelerator fabrics, which Astera claims improves performance in workloads requiring substantial amounts of accessible memory. Internal testing showed up to 62 per cent faster time-to-first-token and 22 per cent more tokens per second, although customers will have to see whether those figures hold up in real-world installations.
The growth comes as data centre operators increasingly confront the limitations of moving information between processors, memory and storage. Faster chips are of limited use when the connections between them cannot keep pace, creating opportunities for specialist suppliers such as Astera to charge healthy margins for removing bottlenecks.
Astera expects fourth-quarter revenue between $730 million and $750 million, representing another substantial sequential increase. The company forecasts a GAAP gross margin of approximately 72 per cent and non-GAAP diluted earnings per share between $1.62 and $1.66, suggesting its extraordinarily profitable run could continue well into the end of the year.
