Forward-looking statements are subject to a number of uncertainties and risks that could cause actual results to differ materially from those anticipated in the forward-looking statements including: Arista Networks’ limited operating history; risks associated with Arista Networks’ rapid growth; Arista Networks’ customer concentration; 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 order patterns or customer mix; increased competition in our products and service markets, including the data center market; dependence on the introduction and market acceptance of new product offerings and standards; rapid technological and market change; the dispute with Cisco Systems, Inc. and OptumSoft, Inc.; the evolution of the cloud networking market and the adoption by end customers of Arista Networks’ cloud networking solutions; and general market, political, economic and business conditions. Additional risks and uncertainties that could affect Arista Networks can be found in Arista’s Annual Report on Form 10-K that was filed with the SEC on March 12, 2015 for the year ended December 31, 2014, 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 non-GAAP results for gross margins, net income and net income per share in addition to, and not as a substitute for, financial measures calculated in accordance with GAAP. 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.

Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP financial measures, and should be read only in conjunction with the company's consolidated financial statements prepared in accordance with GAAP. 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. Arista Networks defines non-GAAP gross margins as total gross profit, excluding stock-based compensation expenses, divided by total revenue.

Arista Networks defines non-GAAP net income as net income, excluding stock based compensation expense, expenses associated with the OptumSoft and Cisco litigation and the related income tax effect of these exclusions. Arista Networks defines non-GAAP net income per share as non-GAAP net income divided by the diluted weighted average shares outstanding on a pro forma basis. In order to evaluate per share information on a comparative basis, the company believes it is meaningful to provide a non-GAAP financial measure that gives pro forma effect to the conversion of the preferred shares and notes payable into common shares and the issuance of common shares in connection with the company’s initial public offering as if each happened at the beginning of each period presented.
