Arista Networks Posts Higher Revenue, Operating Income, and Diluted EPS Year-Over-Year in Filing

Bottom line

The headline conclusion for Arista Networks, Inc. on its interim filing under 10-Q for the three-month reporting period the three months ended March 31, 2026 is straightforward: every top-line and bottom-line measure moved higher than its prior-year comparative, and the company remained profitable on every profitability line, including diluted earnings per share. Specifically, Revenue from Contract with Customer, Excluding Assessed Tax was $2,709,000,000 USD for the three months covered by the three months ended March 31, 2026, higher than the $2,004,800,000 USD reported for the same window in the three months ended March 31, 2025. Operating Income (Loss) was $1,157,800,000 USD versus $858,800,000 USD a year earlier. Net Income (Loss) Attributable to Parent was $1,022,900,000 USD versus $813,800,000 USD, and Earnings Per Share, Diluted was $0.80 per diluted share USD/SHARES versus $0.64 per diluted share USD/SHARES in the prior-year quarter. Both the current and prior-year periods produced profits on each line, so the result remained a profit in the latest quarter rather than slipping to a loss, and the year-over-year direction is upward across the four measures for which comparisons are authorized here. Because the filing evidence provides no cause for the increases, no single driver is asserted: The filing evidence does not attribute this change to any single cause.. The filing evidence also contains no peer or industry comparison, so any cross-company read would require outside data: The filing evidence contains no peer or industry comparison..

The reporting-period identity is the standard Lizely Finance scope for a Form 10-Q style interim: the consolidated statements cover Arista Networks, Inc. (ticker ANET, CIK 0001596532, filing accession 0001596532-26-000078) for the quarterly fiscal period labelled period-ended-2026-03-31. The filing presents unaudited condensed consolidated financial statements that, per management, have been prepared on the same basis as the audited annual statements, include only normal recurring adjustments, and should be read alongside the audited consolidated financial statements and footnotes in the company's prior Annual Report on Form (omitted). Certain prior-period amounts were reclassified to conform to the current presentation, a routine interim disclosure rather than a restatement. Management also notes that the three-month result for the current quarter is not necessarily indicative of the full-year result, which is standard interim language. The source scope for this section is therefore limited to the consolidated income-statement lines captured in the FACT catalog for the three-month window and the prior-year three-month comparative, together with the filing's own basis-of-presentation and use-of-estimates language — not the full notes, segment data, fair-value tiers, the equity note captured by Note 5, or the Part II Items Item 1, Item 1A, Item 2, Item 3, Item 4, Item 5, and Item 6, which fall to other sections of this analysis.

Financial performance

For the three-month reporting period, Arista Networks, Inc. (ANET) reported under 10-Q for period-ended-2026-03-31 (accession 0001596532-26-000078, CIK 0001596532) a top line that widened from the prior-year three-month window. Revenue from Contract with Customer, Excluding Assessed Tax reached $2,709,000,000 USD in the current quarter, compared with $2,004,800,000 USD in the three months ended March 31, 2025, an authorized increase direction on a year-over-year basis.

Profitability moved in step with the top line. Operating Income (Loss) was a profit of $1,157,800,000 USD in the three months ended March 31, 2026, against an operating profit of $858,800,000 USD a year earlier — also an authorized year-over-year increase, with a profit-to-profit transition. Net Income (Loss) Attributable to Parent similarly stayed in profit territory, rising to $1,022,900,000 USD this quarter from $813,800,000 USD in the prior-year quarter. Earnings Per Share, Diluted of $0.80 per diluted share USD/SHARES in the three months ended March 31, 2026 was higher than the prior-year diluted figure of $0.64 per diluted share USD/SHARES, again a profit-to-profit year-over-year shift.

The accounting context that frames these numbers is unchanged in tone. The filing notes that the condensed consolidated balance sheet as of the prior fiscal year-end has been derived from the audited statements but does not include every note or disclosure required by GAAP for a complete set of financial statements, and that certain prior-period amounts were reclassified to conform with the current presentation. Management also flags its reliance on estimates covering inventory valuation, contract manufacturer and supplier liabilities, income taxes, deferred tax assets and liabilities, the valuation allowance on those deferred tax assets, reserves for uncertain tax positions, and revenue recognition and deferred revenue. The filing evidence does not attribute this change to any single cause.

Two new accounting standards are on the horizon but have not yet taken effect. One addresses the disaggregated disclosure of specific income-statement expense categories, including purchases of inventory, employee compensation, depreciation, and amortization, with adoption permitted prospectively or retrospectively. The other updates the form and content of interim financial statements and the principle for disclosing material events since the end of the last annual reporting period. The filing treats both as disclosure-only changes that will, once adopted, simply add further notes to the consolidated financial statements. The filing evidence does not attribute this change to any single cause.

Fair-value measurement remains a Level I and Level II story for cash equivalents, restricted cash, and available-for-sale marketable securities. The company continues to hold no Level III financial assets measured on a recurring basis, invests in debt securities with maximum maturities of three years that it considers low risk, and did not recognize any credit losses or non-credit-related impairments for the three months covered by the report. Unrealized gains and losses flowed through other comprehensive income, while realized gains and losses were immaterial. Marketable debt securities with maturities beyond the shorter operating threshold are classified as current assets. Goodwill carrying value was unchanged over the three months.

Operating drivers and segments

Arista Networks frames itself in this filing as an industry leader in data-driven, client-to-cloud networking for large AI, data center, campus and routing environments, with its cloud networking solutions built around the Extensible Operating System (EOS®), its network applications, and its Ethernet switching and routing platforms. The company notes that its corporate headquarters sit in Santa Clara, California, where it also purchased land and improvements during the year ended December of the referenced period to construct a building for office, lab and data center space. Wholly-owned subsidiaries span North America, Europe, Asia and Australia, so any discussion of operating drivers has to be read against a multi-region cost base rather than a single-country footprint.

On the top line, the company reports Revenue from Contract with Customer, Excluding Assessed Tax of $2,709,000,000 for the three months ended the three months ended March 31, 2026, compared with $2,004,800,000 for the three months ended the three months ended March 31, 2025. That places revenue higher than the prior-year comparative for the three-month reporting period, while both periods remain in positive territory. On operating profitability, the filing shows Operating Income (Loss) of $1,157,800,000 for the three months ended the three months ended March 31, 2026, against $858,800,000 for the three months ended the three months ended March 31, 2025, with operating profit higher than the prior period and the transition again staying profit to profit rather than slipping into a loss.

Because Arista operates as a single reportable segment in this interim filing, there is no separate segment breakout to weigh against the consolidated numbers, so margin commentary cannot be sharpened by product-line or geography splits. The filing evidence does not attribute this change to any single cause. The filing evidence does not attribute the revenue or operating-income movement to any single cause, and management's narrative in the quoted source material is limited to describing the business, the Santa Clara property project, and the upcoming FASB disaggregation standard rather than quantifying price, volume, or mix drivers. Investors therefore have to take the year-over-year improvement as a directional signal without an in-filing explanation of what pulled each line.

Forward-looking standards will reshape how future filings present these drivers. The company highlights ASU (omitted) on the disaggregation of income statement expenses, which will require separate disclosure of purchases of inventory, employee compensation, depreciation, and amortization within relevant income statement captions, plus a selling-expenses total, once adopted. That standard, and the companion ASU on interim disclosure events, will give readers a more granular view of cost behaviour than the current condensed presentation permits. Until those disclosures land, the analytical value of this filing rests on the headline revenue and operating-income comparison, while the underlying drivers — mix, pricing, AI-cycle demand, regional weighting, and the new Santa Clara capacity — remain inferential. The filing evidence contains no peer or industry comparison.

Cash flow and capital

Reported facts — Cash and Cash Equivalents, at Carrying Value stood at $2,789,500,000 USD as of the balance sheet date of March 31, 2026, accompanied by Accounts Receivable, after Allowance for Credit Loss, Current of $1,923,800,000 USD and Accounts Payable, Current of $608,400,000 USD on the same balance sheet date. On the cash flow statement, Net Cash Provided by (Used in) Operating Activities was $1,693,500,000 USD for the three months ended March 31, 2026, compared with $641,700,000 USD for the three months ended March 31, 2025. Net Cash Provided by (Used in) Investing Activities was -$865,300,000 USD for the three months ended March 31, 2026, against -$765,900,000 USD for the three months ended March 31, 2025. Net Cash Provided by (Used in) Financing Activities was $0 USD for the three months ended March 31, 2026, against -$793,800,000 USD for the three months ended March 31, 2025. Within financing, Payments for Repurchase of Common Stock was $0 USD for the three months ended March 31, 2026, against $787,100,000 USD for the three months ended March 31, 2025. Within investing, Payments to Acquire Property, Plant, and Equipment was $54,500,000 USD for the three months ended March 31, 2026, against $28,400,000 USD for the three months ended March 31, 2025.

Management explanations — The filing describes marketable debt securities as short-duration and conservative, with maturities capped at three years, and notes that unrealized gains and losses flow through other comprehensive income while realized amounts were immaterial for the three months covered. Purchase obligations are described as non-cancellable commitments to third-party contract manufacturers covering finished goods, strategic components consigned to those manufacturers, software and technology licenses, property and equipment, and other corporate goods and services; the filing notes limited ability to reschedule. The Stockholders’ Equity narrative describes a board-authorized repurchase program funded from working capital, with repurchases permitted on the open market, via privately negotiated transactions, through investment banking institutions, block purchases, Rule (omitted) trading plans, or a combination, at management's discretion. The filing also discloses an ongoing Santa Clara, California property project for office, lab and data center space.

Analyst inference — The year-over-year movement is consistent with rising operating cash generation and a larger capital expenditure footprint, while the financing line moves from a use of cash in the prior period to roughly flat in the current period. The filing evidence does not attribute this change to any single cause. Capital intensity continues to track property project and capacity build-out, and share repurchases move from active buyback in the prior period to a flat reading in the current period.

Counter-evidence — The filing itself flags that an unfavorable legal outcome, although not currently deemed probable or estimable, could materially affect financial position, results of operations or cash flows in a future period. The filing also discloses indemnification obligations and standby letters of credit that could draw on liquidity, although no related liability has been recorded.

Unknowns — The filing evidence contains no peer or industry comparison.

Peer and historical context

Against the prior-year three-month window, the company's top line moved higher, with Revenue from Contract with Customer, Excluding Assessed Tax rising from $2,004,800,000 USD in the three months ended March 31, 2025 to $2,709,000,000 USD in the three months ended March 31, 2026. Operating Income (Loss) followed the same trajectory, climbing from $858,800,000 USD to $1,157,800,000 USD, and Net Income (Loss) Attributable to Parent expanded from $813,800,000 USD to $1,022,900,000 USD. Each of these three lines remains in profit territory across both windows, so the year-over-year story is one of a larger profit on a larger revenue base, not a swing from loss to gain. Cash from operations tells the same direction: Net Cash Provided by Operating Activities rose from $641,700,000 USD to $1,693,500,000 USD, reinforcing that the income gains are translating into cash rather than just accruals.

- A direct peer set is not disclosed in the cited materials, so no head-to-head comparison against named networking or data-center peers can be drawn from the filing itself. The filing evidence contains no peer or industry comparison. - Long historical series beyond the single prior-year quarter are not provided in the filing evidence, so trend judgments are restricted to the year-over-year pair. - The cited note on stock-based compensation refers to a weighted-average amortization horizon measured in years, but the figure itself is omitted from the quoted passage, limiting any historical comparison of share-based expense.

Scenario analysis

In the base case for Arista Networks, Inc., the company carries forward the profit-to-profit outcome already recorded in 10-Q for period-ended-2026-03-31, with revenue from contract with customer, excluding assessed tax, of $2,709,000,000 USD for the three months ended March 31, 2026 sitting above the $2,004,800,000 USD figure reported for the three months ended March 31, 2025, and net income attributable to parent of $1,022,900,000 USD for the three months ended March 31, 2026 above the $813,800,000 USD figure reported for the three months ended March 31, 2025. The base scenario assumes the conditions that produced those reported results continue without sharp swings in product mix or customer concentration. Stockholders' equity activity captured in Note 5 context continues to be funded from working capital, and the company does not repurchase shares during the next reporting window, consistent with the absence of repurchase activity disclosed for the three months ended March 31, 2026.

The upside case layers the favorable elements already visible in 10-Q: revenue continues higher year over year, and net income remains profitable at a higher level than the prior comparative period. Operating decisions, indemnification provisions, and legal proceedings addressed within Item 1 do not produce an unfavorable outcome, so there is no charge to the provision for contingent losses that management describes as not significant. Unrecognized tax benefits, which the filing treats as not material in the surrounding narrative, remain stable rather than reversing. Under this path, the diluted weighted-average share count captured in the net income per share table drifts modestly because no shares are repurchased, and basic and diluted per-share figures trend with the higher net income base rather than against it.

The downside case keeps revenue and net income at profitable levels but flags the risks already disclosed. Were any of the ordinary-course intellectual property, patent, or contract matters referenced under Item 1 and Item 4 to resolve unfavorably, management warns that there exists the possibility of a material adverse impact on financial position, results of operations, or cash flows for the period in which the unfavorable outcome occurs, and potentially in future periods. Similarly, the indemnification provisions and standby letters of credit discussed in the surrounding narrative could trigger a payout, even though no liability has been recorded to date. Under the downside case, no repurchase activity and an unchanged share count mean basic and diluted share-based figures do not benefit from a reduction in the denominator, leaving any compression in per-share results tied to the income line.

Across all three scenarios, The filing evidence does not attribute this change to any single cause.. The filing evidence contains no peer or industry comparison.. The filing evidence does not disclose segment-level detail for this dimension..

Risks and what to watch

- Reported facts: Arista Networks filed its 10-Q covering period-ended-2026-03-31 under accession 0001596532-26-000078 for Arista Networks, Inc.. The filing's three-month reporting period is the focus of this section, which reviews the three months ended March 31, 2026 against the three months ended March 31, 2025. Net Income (Loss) Attributable to Parent was $813,800,000 USD for the three months ended March 31, 2025 and $1,022,900,000 USD for the three months ended March 31, 2026.

Revenue from Contract with Customer, Excluding Assessed Tax was $2,004,800,000 USD for the three months ended March 31, 2025 and $2,709,000,000 USD for the three months ended March 31, 2026. - Management explanations: The filing's narrative on Stockholders' Equity and Stock-Based Compensation notes that a board-authorized stock repurchase program was renewed in May (omitted) of a prior year. , no shares were repurchased in the current three-month reporting period under that program.

The narrative on Net Income Per Share describes basic and diluted share-count conventions and notes that antidilutive potential common shares are excluded. - Analyst inference: The current-period revenue figure of $2,709,000,000 USD sits above the prior-year $2,004,800,000 USD, and current-period net income of $1,022,900,000 USD sits above the prior-year $813,800,000 USD. Both lines remain profitable year over year, with no period showing a loss.

" That clause is the filing's own risk caveat — not an analyst forecast — and the cited note covers it. - Counter-evidence: No shares were repurchased in the three-month reporting period even though an active authorization was on the books, which can be read as either restraint or as a deliberate use of working capital for other priorities; the filing does not characterize management's intent. The filing evidence does not attribute this change to any single cause.

- Unknowns: The filing evidence does not provide segment-level revenue or income detail, peer or industry comparison figures, customer concentration percentages, backlog size, or any guidance for the next period. Risk-factor text beyond the generic clause, including the substance of Item 1A, is not reproduced in the quoted narrative supplied for this section. Operating cash flow, investing, and financing line items referenced elsewhere in the filing are not quoted here, so any change in those streams cannot be characterized from the supplied evidence.

The filing evidence does not disclose segment-level detail for this dimension. The filing evidence contains no peer or industry comparison. - Metrics to watch next period: (i) whether the share-repurchase pace under the May (omitted) authorization resumes from the zero level recorded in the current three-month reporting period; (ii) the trajectory of revenue relative to the prior-year $2,004,800,000 USD and the current $2,709,000,000 USD; (iii) the trajectory of net income relative to $813,800,000 USD and $1,022,900,000 USD; and (iv) any disclosure of segment-level results or material risk-factor updates in Item 1A or Item 4 of the next interim filing.
