Previous wording

Historically, large purchases by a relatively limited number of customers have accounted for a significant portion of our revenue. For example, sales to our end customer Microsoft represented 20%, 18% and 16% of our total revenue for the years ended 2024, 2023 and 2022, respectively. And sales to our end customer Meta Platforms represented 15%, 21% and 26% of our total revenue, respectively for the years ended 2024, 2023 and 2022. We have experienced unpredictability in the timing of orders from these large customers primarily due to the overall complexity of these large orders and changes in demand specific to these customers, including reductions in or changes in the mix of capital expenditures by these customers and the impact of cost reduction and other efficiency efforts by these customers. In addition, thevariability in customer concentration is linked to the timing of new product deployments, and spending cycles with these customers, as well as the time it takes these customers to evaluate, test, qualify and accept our products and services, and we expect continued variability in our customer concentration and timing of sales on a quarterly and annual basis. In addition, we typically provide pricing discounts to large customers, which reduces gross margins for the period in which such sales occur.

Current wording

Historically, a limited number of customers have accounted for a significant portion of our revenue. Two of our customers accounted for more than 10% of our total revenue in each of the last three years. Sales to one end customer represented 16%, 15%, and 21% of our total revenue, and sales to the other end customer represented 26%, 20%, and 18% of our total revenue for the years ended December 31, 2025, 2024, and 2023, respectively. We have experienced unpredictability in the timing of orders from our high-volume customers, primarily due to the inherent complexity of large-scale orders and fluctuations in their specific demand. This includes reductions or shifts in their capital expenditure budgets, as well as the impact of their internal cost-reduction and efficiency initiatives. Furthermore, variability in customer concentration is driven by the timing of new product deployments, customer spending cycles, and the extensive periods required for evaluation, testing, and qualification. We expect this variability in concentration and sales timing to continue on both a quarterly and annual basis. Additionally, the pricing discounts typically required for these large-scale orders adversely impact our gross margins.

Previous wording

We believe an increased focus on the deployment of AI-enabled solutions by our large customers has accelerated the need for advanced technology offerings, including some offerings from potential new market entrants. This prioritization and acceleration of AI related infrastructure investment has at times come in conjunction with a reduction or changes in the mix of previously planned purchases and various cost reduction measures by these customers, including optimization and increased efficiency in non-AI related capital expenditures. In addition, although the focus on deployment of AI-enabled solutions has driven increased demand for networking, the long-term trajectory is unknown. As such, demand estimates for our new products are difficult to forecast and can create volatility in our revenue. In some instances, such factors have had, and may continue to have, an impact on certain current or future projects and reduce our visibility to customer demand and may result in a reduction or uncertainty in the timing of orders from these large customers and increase the risk of charges for excess and obsolete inventory. We remain in a period of new product introductions and expanded use cases, particularly in the AI Ethernet market. This has resulted in increased customer trials and contracts with acceptance periods, and an increase in the volatility and magnitude of our product deferred revenue balances, which in turn may create variability in our revenue results on a quarterly and annual basis. In addition, if we are not able to satisfy the requirements under customer trials or contracts with acceptance periods, we may be required to accept product returns from our customers, which would prevent us from recognizing revenue on such transactions and may result in the write-down of inventory.

Global economic and business activities continue to face widespread macroeconomic uncertainties, including the effects of, among other things, inflation, monetary policy shifts, recession risks, potential supply chain disruptions, changes in government administration policy positions, and geopolitical pressures, including escalating international trade measures and tariff uncertainty.

Current wording

Global economic and business activities continue to face widespread macroeconomic uncertainties, including the effects of, among other things, inflation, monetary policy shifts, recession risks, supply constraints and potential supply chain disruptions, changes in government administration policy positions, and geopolitical pressures, including the war in Iran and international trade measures and tariff uncertainty.

Previous wording

We are working closely with our contract manufacturers and suppliers to optimize our supply chain and production efforts in response to the uncertainty around international trade policy and tariff rates to minimize the impact of the tariffs and any impact on the supply chain of components sourced from affected countries. While our supply chain has currently not experienced a significant disruption as a result of the recent trade measures, the extent of such policies and tariffs that will ultimately be implemented is unknown at this time, and the future impact to our supply chain and cost of our products is uncertain. We continue to ship products against previously committed demand/deployment plans and accelerate some deployments where needed, while trying to balance our customers' requirements and lead times with the availability of key components and products and lead times of our key suppliers and contract manufacturers. Given the timing and prioritization of customer orders and shipment patterns, as well as the timing and outcome of customer trials and contracts with acceptance periods, near term revenue trends may not be reflective of current demand levels, and could benefit from demand/deployment plans that have been previously committed. We expect that our inventory and purchase commitments will remain volatile as we ramp new product introductions. The magnitude of these balances and shifting customer product priorities, has resulted in an increased risk that we may not be able to sell all of this inventory, which in turn has resulted in excess and obsolete inventory and may result in additional charges to excess and obsolete inventory and supplier liability. In addition, inflation pressure in our supply chain and scarcity of some materials needed to build our products have increased our cost of revenue and have impacted, and may continue to negatively impact our gross margin. These cost pressures may be increased if escalating tariff and non-tariff international trade measures continue to affect our supply chain. We also may not be able to fully mitigate the cost impacts of escalating tariff and non-tariff international trade measures or be able to pass on the full burden of the increase in trade-related costs to our customers, which could further negatively impact our gross margin. While we have seen improvements in our supply chain and manufacturing operations, any remaining or new supply chain and manufacturing-related constraints could negatively impact our business in future periods.

Current wording

Management is actively collaborating with contract manufacturers and suppliers to optimize our supply chain in response to component constraints, evolving international trade policies, and tariff uncertainties. Ongoing supply constraints and future trade measures have and could continue to adversely affect our supply chain stability and increase our product costs. We are maintaining a disciplined fulfillment cadence to ensure reliable inventory deployment. As we build capacity to meet escalating demand, we are shipping products against previously committed demand/deployment plans and accelerating some shipments as needed. Simultaneously, we are balancing customers’ requirements and lead times against the availability and lead times of key components and products from our suppliers and contract manufacturers. Given the timing and prioritization of customer orders and shipment patterns, as well as the timing and outcome of customer trials and contracts with acceptance periods, near term revenue trends may not be reflective of current demand levels and may benefit from demand/deployment plans that have been previously committed.

The increase in the effective tax rates in the three and nine months ended September 30, 2025, as compared to the same periods in 2024, was primarily associated with a one-time deferred tax provision arising from the remeasurement of our basis difference associated with the U.S. tax effect of foreign deferred tax assets resulting from the enactment of the OBBB Act, and a decrease in tax benefits attributable to equity-based compensation. While some specific provisions of the OBBB Act are not effective until our fiscal 2026 period, our deferred method of accounting policy with respect to U.S. tax on foreign earnings, known as global intangible low tax income, requires us to account for these changes in the period of enactment. In addition, we do not anticipate a material impact to our effective tax rate in future periods as a result of the OBBB Act.

Previous wording

Our cash, cash equivalents and marketable securities are held for general business purposes, including the funding of working capital. Our marketable securities investment portfolio is primarily invested in highly-rated securities, with the primary objective of minimizing the potential risk of principal loss. We plan to continue to invest for long-term growth. We believe that our existing balances of cash, cash equivalents and marketable securities, together with cash generated from operations, will be sufficient to meet our working capital requirements and our growth strategies for at least the next 12 months. Our future capital requirements will depend on many factors, including our growth rate, the timing and extent of our spending to support research and development activities, the timing and cost of establishing additional sales and marketing capabilities, the introduction of new and enhanced product and service offerings, our costs associated with supply chain activities, including access to outsourced manufacturing, our costs related to investing in or acquiring complementary or strategic businesses and technologies, the continued market acceptance of our products, stock repurchases, and capital expenditures, including the ongoing construction of a building for office, lab and data center space. In addition, we expect that our inventory and purchase commitments will remain volatile as we ramp new product introductions. In particular, we have increased our purchase commitments to respond to the rapid deployment of AI networks and reduce overall lead times, which may increase our working capital requirements. If we require or elect to seek additional capital through debt or equity financing in the future, we may not be able to raise capital on terms acceptable to us or at all. If we are required and unable to raise additional capital when desired, our business, operating results and financial condition may be adversely affected.

In addition, we expect that our inventory and purchase commitments to remain elevated and subject to volatility as we ramp new product introductions. In particular, we have increased our purchase commitments to respond to the rapid deployment of AI networks, and to navigate the tightening supply within the memory and silicon markets and reduce overall lead times, which will increase our working capital requirements in the future. We regularly review our liquidity and funding sources to support our long-term growth and capital needs.

These cash inflows were partially offset by a $298.7 million increase in other assets driven by increased deferred cost of sales associated with higher product revenue deferrals, and a $133.0 million increase in inventory. The non-cash adjustments to net income were driven by stock-based compensation of $120.9 million, and offset by a $104.9 million increase in deferred taxes primarily due to the increase in deferred revenue.

Previous wording

During the nine months ended September 30, 2024, cash provided by operating activities was $2.7 billion, consisting of net income of $2.1 billion along with a net decrease in working capital requirements of $744.3 million, offset partially by non-cash adjustments to net income of $118.1 million. The decrease in working capital requirements primarily consisted of an increase in deferred revenue of $1.0 billion resulting from an increase in customer PCS contracts and an increase in product deferred revenue related to customer contracts with acceptance terms, a $175.2 million decrease in inventory resulting from strong product shipments, and a $59.8 million increase in income tax payables, net related to timing of payments. These cash inflows were partially offset by a $226.6 million decrease in accounts payable and accrued liabilities primarily due to timing of inventory-related receipts and payments, as well as a reduction in supplier liabilities, an increase in accounts receivable of $96.5 million due to increased product and service billings, and a $173.1 million increase in other assets driven by increased deferred cost of sales associated with higher product revenue deferrals. The non-cash adjustments to net income were driven by a $376.7 million increase in deferred taxes primarily due to the increase in deferred revenue and the capitalization of research and development costs under Section 174 of the IRC, largely offset by stock-based compensation of $254.6 million and depreciation and amortization.

Current wording

During the three months ended March 31, 2025, cash provided by operating activities was $641.7 million, consisting of net income of $813.8 million, offset by a net increase of $159.7 million in working capital requirements.

In May 2025, our board of directors authorized a $1.5 billion stock repurchase program (the "Repurchase Program"). The Repurchase Program does not obligate us to acquire any of our common stock and may be suspended or discontinued by the Company at any time without prior notice. We did not repurchase any shares during the three months ended March 31, 2026. As of March 31, 2026, the remaining authorized amount for repurchases under the Repurchase Program was $817.9 million. Refer to Note 6. Stockholders' Equity and Stock-Based Compensation of the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1, of this Quarterly Report on Form 10-Q for further discussion.

Previous wording

Purchase obligations not recorded on our balance sheet represent an estimate of all non-cancellable open purchase orders and contractual obligations, made either directly by Arista or by our contract manufacturers on our behalf, in the ordinary course of business for which we have not received the goods or services. As of September 30, 2025, we had $4.8 billion of such purchase obligations, of which $4.3 billion are expected to be received within one year, and $0.5 billion are expected to be received after one year. These open purchase orders are considered enforceable and legally binding, and while we may have some limited ability to reschedule and adjust our requirements based on our business needs prior to the delivery of goods or performance of services, this can only occur with the agreement of the related supplier.

Current wording

We outsource most of our manufacturing and supply chain management operations to third-party contract manufacturers, who procure components and assemble products on our behalf. A significant portion of our purchase orders for finished goods and strategic components, including integrated circuits consigned to contract manufacturers, consists of non-cancellable commitments. Our purchase obligations also encompass software and technology licenses, property and equipment, and other corporate goods and services. As of March 31, 2026, we had $8.9 billion of such purchase obligations, of which $7.6 billion are expected to be received within one year, and $1.3 billion are expected to be received after one year. These open purchase orders are considered enforceable and legally binding, and while we may have some limited ability to reschedule and adjust our requirements based on our business needs prior to the delivery of goods or performance of services, this can only occur with the agreement of the related supplier.

Our management’s discussion and analysis of financial condition and results of operations are based on our unaudited condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these unaudited condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. Actual results may differ from these estimates. To the extent that there are material differences between these estimates and our actual results, our future financial statements will be affected. We believe the critical accounting estimates in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of our Annual Report on Form 10-K filed with the SEC on February 18, 2025 reflect our more significant judgments and estimates used in the preparation of the condensed consolidated financial statements. There have been no significant changes to our critical accounting estimates as disclosed in our Annual Report on Form 10-K.
