Arista’s board of directors has approved a four-for-one forward stock split to make Arista’s common stock more accessible to a broader base of investors.

The four-for-one forward stock split will be effected through the filing of an amendment to Arista’s Amended and Restated Certificate of Incorporation that will proportionately increase the authorized shares of common stock.

Our stockholders will receive an additional three shares of common stock for each share held as of the effective time of the filing of the amendment on December 3, 2024. Prior to market open on December 4, 2024, trading is expected to commence on a split-adjusted basis.

For the fourth quarter of 2024, we expect:

•Revenue between $1.85 billion to $1.90 billion

•Non-GAAP gross margin of approximately 63% - 64%; and

•Non-GAAP operating margin of approximately 44%.

Guidance for non-GAAP financial measures excludes certain items, including stock-based compensation expense, intangible asset amortization, and potential non-recurring charges or benefits. A reconciliation of non-GAAP guidance measures to corresponding GAAP measures is not available on a forward-looking basis without unreasonable effort because these exclusions can be uncertain or difficult to predict, including stock-based compensation expense which is impacted by the timing of employee stock transactions, the company’s future hiring and retention needs and the future fair market value of the company’s common stock. The actual amount of these exclusions will have a significant impact on the company’s GAAP gross margin and GAAP operating margin.

Arista's executives will discuss the third quarter 2024 financial results on a conference call at 1:30 p.m. Pacific time today. To listen to the call via telephone, dial (888) 330-2502 in the United States or +1 (240) 789-2713 from international locations. The Conference ID is 5655862.

The financial results conference call will also be available via live webcast on Arista's investor relations website at https://investors.arista.com/. Shortly after the conclusion of the conference call, a replay of the audio webcast will be available on Arista’s investor relations website.

This press release and accompanying table contain certain non-GAAP financial measures including non-GAAP gross profit, non-GAAP gross margin, non-GAAP income from operations, non-GAAP operating margin, non-GAAP net income and non-GAAP diluted net income per share. These non-GAAP financial measures exclude stock-based compensation expense, intangible asset amortization, gains/losses on strategic investments, and the income tax effect of these non-GAAP exclusions. In addition, non-GAAP financial measures exclude net tax benefits associated with stock-based awards, which include excess tax benefits, and other discrete indirect effects of such awards. The company uses these non-GAAP financial measures internally in analyzing its financial results and believes that these non-GAAP financial measures are 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 the comparable GAAP financial measures. 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. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similarly titled measures presented by other companies. 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 have been provided in the financial statement tables included in this press release, and investors are encouraged to review the reconciliation.
