Arista Networks stock falls 18% from record despite no miss; model sees ~$463 target by 2030

Arista Networks shares fell 18.34% in five sessions, from a record close of $216.74 on October 9, 2026, to $176.98 on October 16. The company reported no miss and cut no guidance. Reuters tied the selling to doubts that debt-funded AI infrastructure firms can earn enough to cover their borrowing. Arista held $13,343.3 million in cash and marketable securities and no debt as of June 30, 2026. Its exposure runs through customers, such as neocloud providers, rather than its balance sheet. The stock rebounded 3.37% to $182.95 on October 19. Its forward price-to-earnings ratio dropped to 38.05x from 43.83x on September 30. The next test is November 3, when Arista reports. The Street expects about $3.6 billion in fourth-quarter revenue.

Arista earnings on November 3: Q4 guidance above $3.6B could send the stock soaring

Arista Networks will report third-quarter earnings on November 3, and investors will watch its fourth-quarter outlook most closely. Wall Street expects fourth-quarter revenue of $3.6 billion and earnings of $1.15 per share. The AI networking company makes Ethernet switches that move data between processors in large AI data centres. Analysts expect third-quarter revenue of $3.33 billion and earnings of $1.08 per share, in line with Arista's own forecast of about $3.3 billion. In the second quarter, revenue rose 37.7% from a year earlier to $3.03 billion. Earnings per share were $0.95, up from $0.70. Nvidia and Cisco Systems also compete in AI networking, and Arista relies heavily on spending by major cloud companies.

Arista's 45.4% operating margin dwarfs Vertiv's 19.5%, but Vertiv trades at a lower cash-flow multiple

Arista Networks and Vertiv Holdings both gain as AI data centres come online, but Arista keeps far more of each sales dollar as profit. Arista supplies data-centre networking; Vertiv supplies power and cooling. Arista's second-quarter revenue was $3.036 billion, up 37.7%, with a 45.4% GAAP operating margin. Vertiv reported $3.274 billion in sales, up 24% (18% organic), with a 19.5% GAAP operating margin. A five-point margin drop at constant revenue would cut Arista's operating profit 11.0% and Vertiv's 25.6%. Arista's cushion costs more. Trailing cash-flow multiples were about 45 for Arista and 28 for Vertiv. Vertiv's adjusted free cash flow reached $925 million, helped by favourable working-capital timing.

Arista beat the S&P 500 five years running, a feat only 10 of 484 stocks managed

Arista Networks (ANET), which sells network switches, has beaten the S&P 500 for five straight years. Only 10 of the 484 index members with five years of price data did the same. Chance alone would produce about five such stocks, so luck explains some of the streak. Arista's results suggest more than luck: net income rose in every year, up 416% over the period, while the share price gained 852%. Revenue rose 37.7% year on year in the second quarter of fiscal 2026. Management raised its full-year revenue growth outlook to 40%. Net income growth slowed to 20% in the latest twelve months, from 26% the year before. Arista reports third-quarter results on November 3, 2026.
