- Arista delivered its strongest year-over-year revenue growth since its initial public offering.
- AI networking and enterprise demand supported higher sales and profitability.
- Fourth-quarter guidance keeps execution, supply and infrastructure spending in focus.
Arista Networks reported a record third quarter on Tuesday, November 3, as demand for artificial intelligence infrastructure and enterprise networking drove revenue and profitability higher. The company's official results release said revenue reached 3.66 billion US dollars for the period ended September 30, up 58.5 percent from a year earlier and 20.5 percent from the second quarter.
AI demand supports record quarter
GAAP diluted earnings per share rose to 1.22 US dollars from 0.67 US dollars a year earlier. Non-GAAP diluted earnings per share reached 1.20 US dollars, compared with 0.77 US dollars in the prior-year quarter. GAAP operating margin was 44.9 percent, while the non-GAAP margin reached 49.1 percent.
Arista also introduced open Ethernet rack-scale architectures for scale-up and scale-out AI fabrics with AMD, Arm, Broadcom, d-Matrix, Meta, Microsoft and Qualcomm. The company said its liquid-cooled portfolio can support up to 144 accelerators in one rack and scale to 1,024 XPUs through cross-rack topologies.
Higher targets define the next test
For the fourth quarter, management expects revenue of 3.9 billion to 4.0 billion US dollars, a non-GAAP operating margin of 48 percent to 49 percent and non-GAAP diluted earnings per share of 1.26 to 1.30 US dollars. The adjusted outlook excludes stock-based compensation, intangible amortization and related tax effects, so it is not directly comparable with GAAP earnings.
