CISCO REPORTS FOURTH QUARTER AND FISCAL YEAR 2016 EARNINGS

SAN JOSE, Calif. — August 17, 2016 — Cisco today reported fourth quarter and fiscal year results for the period ended July 30, 2016. Cisco reported fourth quarter revenue of $12.6 billion, net income on a generally accepted accounting principles (GAAP) basis of $2.8 billion or $0.56 per share, and non-GAAP net income of $3.2 billion or $0.63 per share.

“We had another strong quarter, wrapping up a great year. I am particularly pleased with our performance in priority areas including security, data center switching, collaboration, services as well as our overall performance, with revenues up 2% in Q4 excluding the SP Video CPE business,” said Chuck Robbins, CEO of Cisco. “We continue to execute well in a challenging macro environment. Despite slowing in our Service Provider business and Emerging Markets after three consecutive quarters of growth, the balance of the business was healthy with 5% order growth. This growth and balance demonstrates the strength of our diverse portfolio. Our product deferred revenue from software and subscriptions grew 33% showing the continued momentum of our business model transformation.”

“We delivered another solid quarter and a good fiscal year, expanding both our gross margins and operating margins,” said Kelly Kramer, Cisco executive vice president and chief financial officer. “Our strong operational discipline has enabled us to drive growth and margin improvement as we continue to invest in key priority areas such as security, IoT, collaboration, next generation data center and cloud, while also delivering shareholder value.”

Restructuring Plan

Today’s market requires Cisco and our customers to be decisive, move with greater speed and drive more innovation than we’ve seen in our history. Today, we announced a restructuring enabling us to optimize our cost base in lower growth areas of our portfolio and further invest in key priority areas such as security, IoT, collaboration, next generation data center and cloud. We expect to reinvest substantially all of the cost savings from these actions back into these businesses and will continue to aggressively invest to focus on our areas of future growth. The restructuring will eliminate up to 5,500 positions, representing approximately 7 percent of our global workforce, and we will take action under this plan beginning in the first quarter of fiscal 2017.

Gross Margin — On a GAAP basis, total gross margin and product gross margin were 63.1% and 62.2%, respectively. The increase in the product gross margin compared with 59.0% in the fourth quarter of fiscal 2015 was primarily due to continued productivity improvements, the divestiture of the SP Video CPE Business, and to a lesser extent product mix, partially offset by pricing.

Non-GAAP total gross margin and product gross margin were 64.6% and 63.9%, respectively. The increase in non-GAAP product gross margin compared with 63.2% in the fourth quarter of fiscal 2015 was primarily due to continued productivity improvement and to a lesser extent product mix, partially offset by pricing.

The CloudLock acquisition will further enhance Cisco’s security portfolio and build on Cisco’s Security Everywhere strategy, designed to provide protection from the cloud to the network to the endpoint and also aligns with our strategy to deliver more cloud based subscription services.

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 the impact of the challenging macro environment, our ability to successfully invest in key priority areas such as security, IoT, collaboration, next generation data center and cloud, our ability to deliver shareholder value, profitable growth and strong margins, continued growth of our software and subscriptions business, and the size of the restructuring and the amount and timing of the related charges) and the future financial performance of Cisco (including the business outlook for Q1 FY 2017) 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; man-made problems such as cyber-attacks, data protection breaches, computer viruses or 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 May 24, 2016 and September 8, 2015, 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 months and the year ended July 30, 2016 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 net income per share data, and free cash flow 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. Cisco believes that the presentation of free cash flow, which it defines as the net cash provided by operating activities less cash used to acquire property and equipment, to be a

14

liquidity measure that provides useful information to management and investors because of its intent to return a stated percentage of free cash flow to shareholders in the form of dividends and stock repurchases. Cisco further regards free cash flow as a useful measure because it reflects cash that can be used to, among other things, invest in its business, make strategic acquisitions, repurchase common stock and pay dividends on its common stock, after deducting capital investments.

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, impact to cost of sales from purchase accounting adjustments to inventory, acquisition-related/divestiture costs, significant asset impairments and restructurings, significant litigation and other contingencies, significant gains and losses on 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 the Customer Premises Equipment portion of the Service Provider Video Connected Devices business (“SP Video CPE Business”) during the second quarter of fiscal 2016 on November 20, 2015. This release includes, where indicated, financial measures that exclude the SP Video CPE 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 SP Video CPE Business is no longer part of Cisco and will not be part of Cisco on a go forward basis. Cisco’s management also uses the financial measures excluding the SP Video CPE Business in reviewing the financial results of Cisco.
