01—Abstract

Summary

Summary of the 8-K filed November 4, 2025. Cited figures are marked; the original filing is the authoritative source.

Arista Networks reported third-quarter 2025 revenue of $2.308 billiona, up 27.5% year over year and 4.7% sequentially.

GAAP diluted EPS was $0.67b and non-GAAP diluted EPS was $0.75, up 25% from $0.60 a year earlier. Operating leverage was strong: non-GAAP operating margin was 48.6%, down slightly from 49.1% a year ago, and GAAP operating income rose 24.6% to $978.2 million. Service revenue grew 38% year over year to $396.6 million, and product revenue grew 25% to $1.91 billion.

Deferred revenue rose sharply to $3.52 billionc in current liabilities (from $1.73 billion at year-end 2024), and total deferred revenue was about $4.69 billion, which suggests strong forward visibility into future revenue. The main investor concern is margin guidance. For Q4 2025, Arista expects revenue of $2.3-$2.4 billion (roughly flat to up about 4% sequentially), non-GAAP gross margin of 62-63% (versus 65.2% in Q3), and non-GAAP operating margin of 47-48%.

The guided gross margin decline of roughly 220-320 basis points signals either mix shift, pricing pressure, or cost pressure, and management did not explain the drivers in this release. Balance sheet strength is solid, with cash and marketable securities of about $10.1 billiond, $983 million of share repurchases year to date, and a $300 million cash acquisition. Inventory ($2.16 billion) and prepaid expenses and other current assets ($1.43 billion, up from $632 million) both grew significantly and merit monitoring.

03—Questions

Frequently Asked Questions

  1. Why is Arista guiding to a lower gross margin for Q4 2025?

    The press release does not explain the guidance drivers. The guided non-GAAP gross margin of 62-63% compares with 65.2% in Q3 2025. Likely contributors include product and customer mix, component cost, or pricing, but investors should review the earnings call commentary for management's explanation.

  2. How strong is demand visibility heading into Q4?

    Deferred revenue rose substantially, with current deferred revenue of $3.52 billion versus $1.73 billion at year-end 2024, and total deferred revenue of about $4.69 billion. Accounts receivable also rose to $1.49 billion from $1.14 billion. Together these suggest strong bookings and backlog, though the increase in receivables and deferred revenue timing should be monitored.

  3. Is the difference between GAAP and non-GAAP results material?

    Yes. For Q3 2025, stock-based compensation was $127.9 million and intangible amortization was $15.8 million in operating expenses. GAAP operating margin was 42.4% versus 48.6% non-GAAP, and GAAP diluted EPS was $0.67 versus $0.75 non-GAAP. Non-GAAP net income also excludes a one-time $34.6 million tax charge from the OBBB Act and tax benefits on stock awards of $49.0 million, which reduce the gap.

  4. How is Arista using its cash and what are the balance sheet risks?

    Arista repurchased $983 million of stock in the first nine months of 2025, versus $299.8 million a year earlier, and paid $300 million in cash for a business combination. Operating cash flow was $3.11 billion for the nine months. Risks include the sharp increase in inventory to $2.16 billion, prepaid and other current assets rising to $1.43 billion from $632 million, and total liabilities rising to $6.14 billion, driven largely by deferred revenue.
