Arista Networks, Inc. — FY2023 Form 10-K
Reporting period: Fiscal year ended December 31, 2023. This is an annual filing; the financial statements presented do not provide a separate Q4 income statement. Unless otherwise noted, amounts are U.S. dollars.
Business context
Arista sells Ethernet switching and routing platforms, networking software and support services, primarily to cloud and data-center customers, with expanding campus, routing and security offerings. Product sales accounted for 85.8% of FY2023 revenue. Microsoft and Meta represented 18% and 21% of revenue, respectively, underscoring customer concentration.
Financial performance and liquidity
| Metric | FY2023 | FY2022 | Change |
|---|---|---|---|
| Revenue | $5.860 billion | $4.381 billion | +33.8% |
| Gross profit / margin | $3.630 billion / 61.9% | $2.676 billion / 61.1% | Margin +0.8 percentage points |
| Operating income | $2.257 billion | $1.527 billion | +47.8% |
| Net income | $2.087 billion | $1.352 billion | +54.3% |
| Diluted EPS | $6.58 | $4.27 | +54.1% |
| Cash from operations | $2.034 billion | $492.8 million | Up from prior year |
Operating margin was approximately 38.5%, versus 34.9% in FY2022; net margin was approximately 35.6%, versus 30.9%. Higher revenue and improved product margins contributed to growth. Operating cash flow increased substantially, while inventory rose $655.5 million and accounts receivable rose $101.5 million, partly offset by higher deferred revenue and payables.
Cash, cash equivalents and marketable securities totaled approximately $5.008 billion at year-end, including $770.3 million held outside the U.S. Current assets were $8.390 billion and current liabilities $1.910 billion. The balance sheet reports no debt borrowings. Management said existing liquidity and operating cash flow should cover working capital and growth plans for at least 12 months.
Material changes versus FY2022
- Product revenue grew 35.3% to $5.029 billion; service revenue grew 24.9% to $830.7 million. Management attributed higher shipments to broader customer demand and improved supply availability, including for enterprise customers.
- Gross margin rose to 61.9% from 61.1%, reflecting lower revenue mix from large customers and better fixed-cost leverage, partly offset by higher inventory-related charges.
- Operating expenses increased 19.5% to $1.373 billion, with R&D up 17.4%, sales and marketing up 22.0%, and G&A up 27.7%.
- Other income increased to $164.8 million, largely because interest income rose to $152.4 million from $27.6 million amid higher rates and larger cash and investment balances.
- Operating cash flow improved from $492.8 million to $2.034 billion. Cash used for share repurchases declined to $112.3 million from $670.3 million.
Outlook, commentary and risks
The filing provides no specific numerical FY2024 revenue or earnings guidance. Management expects shorter customer planning horizons and reduced demand visibility as supply constraints ease; near-term revenue may still benefit from orders and deployment plans previously committed. Inventory and working capital may remain elevated near term, and purchase commitments are expected to decline as supplier lead times shorten.
- Inventory and commitments: Inventory was $1.945 billion, up from $1.290 billion. FY2023 charges included $234.4 million of inventory write-downs and $113.0 million of supplier-liability charges. Non-cancellable purchase commitments were $1.587 billion, of which $1.547 billion were expected within 12 months.
- Customer concentration and demand: Microsoft and Meta together represented 39% of revenue. Changes in their spending, AI investment priorities, project timing or vendor allocations could materially affect results.
- AI and competition: Arista is developing AI Ethernet offerings, but the AI market is evolving and customer adoption is uncertain; Ethernet also competes with established InfiniBand and other interconnects.
- Supply chain and geopolitics: Reliance on contract manufacturers and limited-source components creates exposure to shortages, costs, delivery delays, tariffs, export controls and geopolitical disruption.
- Legal contingency: WSOU patent litigation remains unresolved following a favorable 2023 PTAB ruling on challenged claims. The company said loss was reasonably possible but not probable; any loss range could not be estimated.
- Taxes: Capitalization of R&D costs under IRC Section 174 created an approximately $191.7 million incremental cash-tax impact for FY2023, substantially all paid. The company expects cash tax outlays to exceed income tax expense over the next three years unless legislation changes.
Important facts for investors to verify
- Whether Microsoft and Meta spending and concentration changed after year-end, and how much FY2024 demand reflects previously committed deployments versus new orders.
- Inventory quality, subsequent inventory write-downs, supplier liabilities, and the conversion of $1.587 billion in purchase commitments into shipments and sales.
- Cash-flow sustainability after the unusually large working-capital movements, including inventory and deferred revenue.
- Adoption, competitive position and margins of AI Ethernet and adjacent campus, routing and security products.
- Updates to the WSOU case and the cash-tax implications of IRC Section 174 and other tax changes.
- Capital allocation: the repurchase program had $144.5 million remaining at year-end and expires in Q4 2024; the company does not anticipate paying dividends.
