Arista lifts outlook, shares extend rebound

Arista Networks (ANET) shares rallied on November 12, 2026, after the company raised its revenue outlook and highlighted sustained growth momentum following third-quarter results. In U.S. trading, the stock climbed 4.3% in mid-day dealings to $205.20 and was later quoted at $205.62, up 4.55%. The move extended a recovery from a multi-week decline after the third-quarter earnings report and pushed the stock above its 50-day moving average of approximately $192.35. Even after the rebound, the share price remained about 6% below its 52-week high of $217.41, leaving it still off peak levels.

On the European market, Arista traded at 178.40 euros on Lang & Schwarz at 15:39 CET on November 12, up 1.11% from 176.44 euros earlier the same day. The stock thus showed strength across trading venues as investors digested updated guidance and record financial metrics.

Arista reported third-quarter revenue of $3.66 billion on November 3, an increase of 58.5% from the same period a year earlier. Adjusted earnings per share reached $1.20, exceeding a consensus estimate of $1.08. On a GAAP basis, diluted earnings per share were $1.22. The company also reported a GAAP operating margin of 44.9% and a non-GAAP operating margin of 49.1%, underscoring strong profitability alongside rapid top-line expansion.

Building on these results, management raised full-year 2026 revenue guidance to approximately $13.3 billion. The company also provided initial 2027 guidance, targeting revenue growth of 38% to 40%, which would bring revenue to roughly $18.5 billion at the midpoint of the range.

The upgraded outlook and strong quarter prompted a series of analyst price-target increases. Newly cited targets include $291 from UBS, $261 from Piper Sandler, $270 from JPMorgan, $230 from Morgan Stanley, and $305 from Melius. Truist Securities reiterated its Buy rating on Arista shares, viewing the pullback prior to the rebound as a buying opportunity rather than a structural negative.

The stock’s move above its 50-day moving average was viewed as technically significant and came against a backdrop of continued AI-related demand. AI infrastructure spending by hyperscalers such as Microsoft (MSFT) and Meta (META) is supporting uptake of Arista’s networking offerings, and a raised outlook from cloud provider CoreWeave (CRWV) earlier in the week reinforced expectations for ongoing AI data center investment. Management highlighted AI networking and rack-scale architecture expansion as central themes in the company’s growth strategy.

Arista’s record third-quarter growth and higher guidance raise execution demands as the company seeks to sustain its position in AI-centric data center networking. AI networking remains a core focus as Arista expands its rack-scale architecture portfolio, aiming to serve hyperscale and cloud workloads. The combination of rapid revenue growth, high operating margins, and elevated AI demand has set a high bar for future performance as the company approaches its updated 2026 and 2027 revenue targets.
