How it makes money

Sales of connectivity chips, boards, and modules100%

Shares of revenue are estimates for FY2025, not figures from a filing.

Competes with

What it sells5

Aries retimers and smart cable modules
Chips and cable modules that restore weakened high-speed signals so data can travel between processors, storage, and network equipment.
Taurus Ethernet smart cable modules
Modules that extend the reach and increase the speed of Ethernet connections between servers and network switches, including over copper cables.
Leo Compute Express Link (CXL) memory controllers
Chips and boards that let servers add, share, or pool memory for workloads that need more memory capacity or bandwidth.

Show 2 more

Scorpio smart fabric switches
Switches that connect processors and other devices in artificial-intelligence systems, directing data between them.
COSMOS software suite
Software embedded in the company’s chips, boards, and modules that helps customers configure, monitor, troubleshoot, and manage those products.

Who buys it3

Large cloud-computing operators buy products for their data centers, often specifying designs and placing orders for particular products.
Artificial-intelligence accelerator makers work with Astera Labs on designs that connect their processors within computing systems.
Server makers and other system manufacturers incorporate the chips and modules into equipment; orders and invoices may be handled through contract manufacturers or distributors.

What it stands on, and what could break it

What the business leans on

1The three largest end customers accounted for 86% of revenue (FY2025, high).
2Taiwan Semiconductor Manufacturing Company fabricates all of Astera Labs’ integrated circuits.
3A limited number of outside companies handle chip assembly, packaging, and testing, as well as the production of boards and modules.
4Demand depends on cloud data-center and artificial-intelligence infrastructure spending and on customers adopting Astera Labs’ products in their system designs.

What could go wrong

1The three largest end customers accounted for 86% of revenue (FY2025, high), so a loss of a major customer or a reduction in its orders could materially affect sales.
2Astera Labs relies on a small number of outside manufacturers and has no long-term supply contracts with them; supply disruption or manufacturing quality problems could delay product deliveries.
3Export restrictions and changing trade rules, particularly those affecting China, could limit sales to some customers or disrupt access to suppliers.
