Products & services

Astera Labs’ product portfolio includes Aries PCIe/CXL Smart DSP Retimers and Smart Cable Modules, which recover and retransmit high-speed signals to extend interconnect reach and support higher bandwidth, lower-latency connections. Aries cable modules integrate a retimer IC and peripheral components for active electrical cable assemblies; the product line supports PCIe 6.x/CXL 3.x and 8- or 16-lane configurations.[10][11]

Taurus Ethernet Smart Cable Modules use Taurus ICs to extend Ethernet signaling reach and increase bandwidth between servers and switches, with the product page describing 100G-per-lane connectivity.[12][13] Leo CXL Memory Connectivity Controllers and boards expand, share, and pool DRAM over high-speed serial links. Leo 2 E-Series supports CXL 3.2 and PCIe 6 x16 host connectivity with four DDR4/DDR5 controllers; P-Series offers dual-port PCIe 6 2×8 connectivity for memory pooling and sharing.[14][15]

Scorpio Smart Fabric Switches are designed for AI-platform connectivity: P-Series supports mixed-traffic connections among PCIe hosts and endpoints, while X-Series targets GPU-to-GPU connectivity and platform-specific configurations. The product page lists P-Series options from 32 to 320 lanes.[16][17] COSMOS software is integrated with Astera Labs’ connectivity products and customer systems to support configuration, management, monitoring, optimization, troubleshooting, and customization.[18][19] The Q2 2026 filing identifies Aries, Scorpio, and Taurus demand, along with a higher mix of hardware modules and Scorpio products, as contributors to revenue growth; it does not provide revenue percentages by product family.[20] [10]+10

The company describes four product families, but does not disclose revenue or percentage contributions for them separately: Aries provides PCIe/CXL Smart DSP Retimers and Smart Cable Modules; Taurus provides Ethernet Smart Cable Modules; Leo provides CXL Memory Connectivity Controllers; and Scorpio provides Smart Fabric Switches. These are product categories, not separately reported operating segments, and no supported approximate percentage breakdown by family is available.[26][27] [24]+3

Company history

Astera Labs was incorporated in Delaware in October 2017. Its co-founders included Jitendra Mohan and Sanjay Gajendra, who became CEO and COO, respectively; Casey Morrison is also identified as a co-founder.[28][29]

In 2019, the company introduced its Aries Smart Retimer portfolio for PCIe interconnects. By 2020, Aries PCIe 4.0 products were in mass production and PCIe 5.0 products were being sampled; Astera also launched a Cloud-Scale Interop Lab. Over the following years, it broadened its portfolio with Taurus Smart Cable Modules and Leo CXL memory controllers.[30]+2

In March 2024, Astera began trading on Nasdaq under the symbol ALAB and announced Aries 6 products for PCIe 6.x and CXL 3.x. It introduced its Scorpio Smart Fabric Switch portfolio in October 2024. In 2025, the company agreed to acquire and subsequently completed its acquisition of photonics company aiXscale. In 2026, it named Desmond Lynch CFO, succeeding Mike Tate, who moved to a strategic-advisor role.[33]+5 [28]+20
