Forward-Looking Statements

This press release contains “forward-looking statements” regarding our future performance, including statements in the section entitled “Financial Outlook,” such as estimates regarding revenue, non-GAAP gross margin and non-GAAP operating margin for the fourth quarter of fiscal 2017, and statements regarding the benefits from the introduction of new products. Forward-looking statements are subject to known and unknown risks, uncertainties, assumptions and other factors that could cause actual results, performance or achievements to differ materially from those anticipated in or implied by the forward-looking statements including risks associated with: Arista Networks’ dispute with Cisco Systems, Inc. including the ITC remedial orders which prohibit the importation of Arista products (or components thereof) into the U.S., or the sale of previously imported products, that are covered by those remedial orders, Arista Networks’ ability to redesign its products in a manner not covered by such remedial orders and obtain appropriate governmental approvals for those redesigned products, any penalties assessed by the ITC if Arista’s redesigned products are covered by such remedial orders and Arista Networks’ ability to manage our manufacturing and supply chain including the sourcing of components on commercially reasonable terms; Arista Networks’ limited operating history; Arista Networks’ rapid growth; Arista Networks’ customer concentration; our customer’s adoption of our redesigned products and services; requests for more favorable terms and conditions from our large end customers; declines in the sales prices of our products and services; changes in customer demand for our products and services, customer order patterns or customer mix; the timing of orders and manufacturing and customer lead times; increased competition in our products and service markets; dependence on the introduction and market acceptance of new product offerings and standards; rapid technological and market change; the evolution of the cloud networking market and the adoption by end customers of Arista Networks’ cloud networking solutions; Arista Networks’ dispute with OptumSoft; and general market, political, economic and business conditions. Additional risks and uncertainties that could affect Arista Networks can be found in Arista’s most recent Quarterly Report on Form 10-Q filed with the SEC on August 4, 2017, and other filings that the company makes to the SEC from time to time. You can locate these reports through our website at and on the SEC’s website at All forward-looking statements in this press release are based on information available to the company as of the date hereof and Arista Networks disclaims any obligation to publicly update or revise any forward-looking statement to reflect events that occur or circumstances that exist after the date on which they were made.

Non-GAAP Financial Measures

The company reports certain non-GAAP financial measures that exclude stock-based compensation expense and related excess tax benefits, expenses associated with the OptumSoft and Cisco litigation, other non-recurring charges or benefits, and the income tax effect of these non-GAAP exclusions. The company uses these non-GAAP financial measures internally in analyzing its financial results and believes that the use of these non-GAAP financial measures is useful to investors as an additional tool to evaluate ongoing operating results and trends. In addition, these measures are the primary indicators management uses as a basis for its planning and forecasting for future periods.

Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP net income, net income per diluted share, gross margin, or operating margin. Non-GAAP financial measures are subject to limitations, and should be read only in conjunction with the company's consolidated financial statements prepared in accordance with GAAP. A description of these non-GAAP financial measures and a reconciliation of the company’s non-GAAP financial measures to their most directly comparable GAAP measures has been provided in the financial statement tables included in this press release, and investors are encouraged to review the reconciliation.

The Company’s guidance for non-GAAP financial measures excludes stock-based compensation expense and related excess tax benefits, expenses associated with the OptumSoft and Cisco litigation, and other non-recurring items. The Company has not reconciled its non-GAAP gross margin or its non-GAAP operating margin guidance to GAAP gross margin or GAAP operating margin, because we do not provide guidance on GAAP gross margin or GAAP operating margin or the various reconciling items between GAAP gross margin and GAAP operating margin and non-GAAP gross margin and non-GAAP operating margin. Stock-based compensation expense is impacted by the Company’s future hiring and retention needs and the future fair market value of the Company’s common stock. In addition, excess tax benefits on stock-based awards will fluctuate based on these same factors, as well as the timing of exercise or vesting of such awards, all of which are difficult to predict and subject to constant change. The actual amount of stock-based compensation expense and excess tax benefits will have a significant impact on the Company’s GAAP gross margin and GAAP operating margin. Accordingly, a reconciliation of the non-GAAP financial measure guidance to the corresponding GAAP measure is not available without unreasonable effort.
