The company’s growth is driven by strong demand in rack-scale AI infrastructure and hyperscale cloud deployments, with its Taurus PCIe/CXL connectivity solutions seeing a fourfold revenue increase in 2025 and expected to continue growing as 800G switch adoption accelerates.
Scorpio switchable fabric products, including the P-Series and emerging X-Series, contributed significantly, while Leo CXL memory expansion solutions are set for further adoption.

Strong partnerships with hyperscale cloud customers, coupled with high-margin product expansion, position ALAB to capture outsized market share in AI infrastructure.
