Arista Networks Financial Performance: Revenue, EPS, and Margins
The central result in this Arista Networks, Inc. earnings analysis is the size of the top-line beat. Revenue of $3.66B exceeded consensus by $330M. EPS of $1.20 topped the $1.08 estimate by $0.12. That combination gives the report more weight than a narrow earnings beat because sales also cleared the market's target.
The quarterly financial series shows revenue rising from $2.31B in September 2025 to $2.49B in December, $2.71B in March, $3.04B in June, and $3.66B in September 2026. Net income followed the same path, moving from $0.85B to $0.96B, $1.02B, $1.21B, and $1.56B across those periods. The figures show a business expanding both sales and earnings in each listed quarter.
The earnings surprise history adds another layer. Actual EPS was $0.75 on Nov. 4, 2025, $0.82 on Feb. 12, 2026, $0.87 on May 5, $1.02 on Aug. 4, and $1.20 in the latest report. Arista has therefore posted a steady sequence of higher reported EPS figures across the five listed reports.
Arista's latest annual segment figures provide the clearest product and service view. For the year ended Dec. 31, 2025, product revenue was $7.5769B and service revenue was $1.4288B. In 2024, product revenue was $5.8840B and service revenue was $1.1191B. Product remains the larger revenue stream, while both reported categories increased year over year.
The preceding quarter's financial detail also provides a useful margin baseline. CFO Chantelle Breithaupt reported gross margin of 63.4%, compared with 65.6% in the prior year and 62.4% in the prior quarter. She cited customer mix and tariff refunds as factors behind the sequential improvement, while end-customer mix pressured the year-over-year comparison.
That quarter also included $411M of operating expenses, equal to 13.5% of revenue, and $278.1M of research and development spending, or 9.2% of revenue. Operating income reached $1.5B, or 49.9% of revenue, while net income reached $1.3B, or 42.9%. The spending profile shows Arista funding liquid cooling, high-Radix switching, and AI software while maintaining a large operating profit.

ANET finished at $169.91, up 3.52%, with 12,233,896 shares changing hands against an average volume of 5,977,884. The regular-session move and heavier trading activity gave the earnings beat a supportive market response.
Analyst positioning was already favorable before the report. Evercore ISI reiterated Outperform with a $250 price target on Nov. 3, when the stock traded at $168.86. The firm noted that ANET had fallen 4.7% over the prior week, setting a relatively demanding test for the earnings report.
The most notable positive target action came from Citi analyst Atif Malik, who maintained a Buy rating and raised the price target from $215 to $248. Bernstein analyst Daniel Zhu initiated coverage with an Outperform rating and a $250 target. Those actions place fresh analyst targets well above the $169.91 closing price.
The recent tape also includes a valuation caution. TD Cowen analyst Sean O'Loughlin cut the target from $250 to $205 on Oct. 19 while keeping a Buy rating. The change lowered the target without changing the underlying rating. A Benzinga ratings snapshot showed four upgrades, zero downgrades, and seven initiations, while the broader consensus remained Buy.
Analyst commentary after the report focused on AI networking demand, share gains in cloud and data-center networking, raised guidance, and margin strength. The split between Citi's target increase and TD Cowen's target cut captures the current debate around ANET: the operating thesis remains strong, but valuation still sets a high bar.
Management Commentary: AI Scale and Supply Chain Execution
CEO Jayshree Ullal framed Arista's opportunity around the rapid expansion of AI fabrics and the limits of power, space, and compute capacity. Her message was strategic rather than promotional: network design becomes more important when customers need higher accelerator utilization without adding unnecessary tiers or power demand.
"Our AI fabrics momentum with Etherlink switches now exceeds 100 cumulative customers from the initial 4 to 5 customers I spoke of in 2024." - Jayshree Ullal, Chairperson and CEO, Earnings Call
Ullal also placed a number on the opportunity. She said Scale-Across switching and routing represented a forecasted $15B to $20B total addressable market in 2030. She added that Scale-Across represented about 30% of Arista's overall AI target of at least $3.6B in 2026.
"We are now projecting 40% annual growth, which is an incremental $2.1 billion over our Analyst Day goal of $10.5 billion." - Jayshree Ullal, Chairperson and CEO, Earnings Call
The CEO also addressed supply constraints. Arista's multiyear purchase commitments reached approximately $9.7B by the end of the second quarter, compared with $3.6B a year earlier. Chief Operating Officer Todd Nightingale said the company had three contract manufacturers and three distribution facilities across the U.S., Asia, and Mexico.
"The overall gross margin in Q2 was 63.4%, down from 65.6% in the prior year, driven by end customer mix and up from 62.4% in the prior quarter." - Chantelle Breithaupt, CFO, Earnings Call
Breithaupt's financial detail showed where management is spending to support the next phase. Research and development totaled $278.1M in the preceding quarter, with investment directed toward liquid cooling, high-Radix switching, and AI-optimizing software. International revenue reached $697.8M, equal to 23% of total revenue, compared with 15.5% in the prior quarter.
"It's great to see the supply chain ecosystem gaining traction to meet our customers' demand." - Chantelle Breithaupt, CFO, Earnings Call
That comment connects the financial numbers to the guidance increase. Arista is not describing demand as the constraint. The stated focus is converting demand into shipments through supplier commitments, manufacturing capacity, and inventory planning. For a networking company serving AI deployments, that execution point matters as much as the product roadmap.
ANET delivered the combination investors want from a growth hardware company: a $3.66B revenue beat, $1.20 EPS, rising net income, and higher 2026 guidance. AI fabric adoption, supply-chain investment, and a Buy analyst consensus support the growth narrative, while the $205 to $250 range in recent targets shows that valuation remains part of the debate.
The next phase of the Arista Networks story rests on execution. The $12.6B revenue target gives the market a clear benchmark, and the latest gains show that the earnings beat has strengthened confidence in the company’s AI networking position.
