Arista Q3 adjusted EPS is $1.20, below $1.22 under GAAP
Arista's adjustments increase operating profit but reduce net income. Investment gains and tax benefits explain why the two comparisons run in different directions.
Adjusted earnings do not automatically mean bigger earnings. Arista Networks' latest results offer a useful example: its non-GAAP operating profit is higher than the GAAP figure, while adjusted earnings per share are lower.
Arista (NYSE: ANET) disclosed the results in its November 3 release. The unaudited quarter ended September 30, 2026; figures below are U.S. dollars.

Its reconciliation adds $138.1 million of stock-based compensation and $15.3 million of intangible-asset amortization to GAAP operating income, taking it from $1,642.4 million to $1,795.8 million.
At net income, it also removes $134.5 million of strategic-investment gains, $40.0 million of stock-award tax benefits and an $8.5 million tax effect on non-GAAP exclusions.
Net income consequently falls $29.6 million, from $1,560.4 million GAAP to $1,530.8 million non-GAAP. Both diluted EPS calculations use 1,278.2 million weighted-average shares.
That shared denominator matters. The lower adjusted EPS comes from the earnings reconciliation, rather than a different share count between the two measures. The effect is small per share, but the direction is a reminder to read the actual bridge instead of assuming every exclusion boosts the bottom line.
Operating profit asks how the business performed before items further down the income statement. Net income also reflects investment and tax effects. A favorable item included under GAAP can disappear from an adjusted measure just as an expense can.
For investors comparing networking companies, the useful habit is to check both the exclusions and where they enter the statement. These figures do not establish whether an investment gain will recur, when it becomes cash, or what Arista's AI business earns separately. The reconciliation clarifies the reported quarter; it is not a forecast.
