Forward Looking Statements, Non-GAAP Information and Additional Information

This release may be deemed to contain forward-looking statements, which are subject to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, among other things, statements regarding future events (such as our ability to continue to drive innovation, our long-term growth opportunities as we help our customers build out the networks for the future, the continued strength of our ongoing cash flows and our ability to continue to return value to our shareholders) and the future financial performance of Cisco (including the guidance for Q3 FY 2020) that involve risks and uncertainties. Readers are cautioned that these forward-looking statements are only predictions and may differ materially from actual future events or results due to a variety of factors, including: business and economic conditions and growth trends in the networking industry, our customer markets and various geographic regions; global economic conditions and uncertainties in the geopolitical environment; overall information technology spending; the growth and evolution of the Internet and levels of capital spending on Internet-based systems; variations in customer demand for products and services, including sales to the service provider market and other customer markets; the return on our investments in certain priorities, key growth areas, and in certain geographical locations, as well as maintaining leadership in routing, switching and services; the timing of orders and manufacturing and customer lead times; changes in customer order patterns or customer mix; insufficient, excess or obsolete inventory; variability of component costs; variations in sales channels, product costs or mix of products sold; our ability to successfully acquire businesses and technologies and to successfully integrate and operate these acquired businesses and technologies; our ability to achieve expected benefits of our partnerships; increased competition in our product 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; manufacturing and sourcing risks; product defects and returns; litigation involving patents, intellectual property, antitrust, shareholder and other matters, and governmental investigations; our ability to achieve the benefits of the announced restructuring and possible changes in the size and timing of the related charges; cyber-attacks, data breaches or malware; vulnerabilities and critical security defects; terrorism; natural catastrophic events; a pandemic or epidemic; our ability to achieve the benefits anticipated from our investments in sales, engineering, service, marketing and manufacturing activities; our ability to recruit and retain key personnel; our ability to manage financial risk, and to manage expenses during economic downturns; risks related to the global nature of our operations, including our operations in emerging markets; currency fluctuations and other international factors; changes in provision for income taxes, including changes in tax laws and regulations or adverse outcomes resulting from examinations of our income tax returns; potential volatility in operating results; and other factors listed in Cisco’s most recent reports on Forms 10-Q and 10-K filed on November 19, 2019 and September 5, 2019, respectively. The financial information contained in this release should be read in conjunction with the consolidated financial statements and notes thereto included in Cisco’s most recent reports on Forms 10-Q and 10-K as each may be amended from time to time. Cisco’s results of operations for the three and six months ended January 25, 2020 are not necessarily indicative of Cisco’s operating results for any future periods. Any projections in this release are based on limited information currently available to Cisco, which is subject to change. Although any such projections and the factors influencing them will likely change, Cisco will not necessarily update the information, since Cisco will only provide guidance at certain points during the year. Such information speaks only as of the date of this release.

This release includes non-GAAP net income, non-GAAP gross margins, non-GAAP operating expenses, non-GAAP operating income and margin, non-GAAP effective tax rates, non-GAAP interest and other income (loss), net, and non-GAAP net income per share data for the periods presented. It also includes future estimated ranges for gross margin, operating margin, tax provision rate and EPS on a non-GAAP basis.

These non-GAAP measures are not in accordance with, or an alternative for, measures prepared in accordance with generally accepted accounting principles and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. Cisco believes that non-GAAP measures have limitations in that they do not reflect all of the amounts associated with Cisco’s results of operations as determined in accordance with GAAP and that these measures should only be used to evaluate Cisco’s results of operations in conjunction with the corresponding GAAP measures.

Cisco believes that the presentation of non-GAAP measures when shown in conjunction with the corresponding GAAP measures, provides useful information to investors and management regarding financial and business trends relating to its financial condition and its historical and projected results of operations.

For its internal budgeting process, Cisco’s management uses financial statements that do not include, when applicable, share-based compensation expense, amortization of acquisition-related intangible assets, acquisition-related/divestiture costs, significant asset impairments and restructurings, significant litigation settlements and other contingencies, gains and losses on equity investments, the income tax effects of the foregoing and significant tax matters. Cisco’s management also uses the foregoing non-GAAP measures, in addition to the corresponding GAAP measures, in reviewing the financial results of Cisco. In prior periods, Cisco has excluded other items that it no longer excludes for purposes of its non-GAAP financial measures. From time to time in the future there may be other items that Cisco may exclude for purposes of its internal budgeting process and in reviewing its financial results. For additional information on the items excluded by Cisco from one or more of its non-GAAP financial measures, refer to the Form 8-K regarding this release furnished today to the Securities and Exchange Commission.

Cisco divested its Service Provider Video Software Solutions business (SPVSS) during the second quarter of fiscal 2019 on October 28, 2018. This release includes, where indicated, financial measures that exclude the SPVSS business. Cisco believes that the presentation of these measures provides useful information to investors and management regarding financial and business trends relating to its financial condition and its historical and projected results of operations because the SPVSS business will not be part of Cisco on a go forward basis. Cisco’s management also uses the financial measures excluding the SPVSS business in reviewing the financial results of Cisco.
