Our guidance with respect to non-GAAP financial measures excludes stock-based compensation, amortization of acquired intangible assets and gain on intellectual property matter. We have not reconciled our guidance with respect to non-GAAP financial measures to the corresponding GAAP measures because certain items that impact these measures are uncertain or out of our control, or cannot be reasonably predicted. Accordingly, a reconciliation of these non-GAAP financial measures to the corresponding GAAP measures is not available without unreasonable effort.

This press release contains forward-looking statements that involve risks and uncertainties. These forward-looking statements include statements regarding demand for our products and services, guidance and expectations around future financial results, including guidance and expectations for the second quarter and full year 2021, statements regarding the momentum in our business and future growth expectations and objectives and statements regarding growth in market demand. Although we attempt to be accurate in making forward-looking statements, it is possible that future circumstances might differ from the assumptions on which such statements are based such that actual results are materially different from our forward-looking statements in this release. Important factors that could cause results to differ materially from the statements herein include the following: general economic risks, including those caused by the COVID-19 pandemic; negative impacts from the COVID-19 pandemic on sales, billings, revenue, demand and buying patterns, component supply and ability to manufacture products to meet demand in a timely fashion, and costs such as possible increased costs for shipping and components; global economic conditions, country-specific economic conditions, and foreign currency risks; competitiveness in the security market; the dynamic nature of the security market and its products and services; specific economic risks worldwide and in different geographies, and among different customer segments; uncertainty regarding demand and increased business and renewals from existing customers; uncertainties around continued success in sales growth and market share gains; actual or perceived vulnerabilities in our supply chain, products or services, and any actual or perceived breach of our network or our customers' networks; longer sales cycles, particularly for larger enterprise, service providers, government and other large organization customers; the effectiveness of our salesforce and failure to convert sales pipeline into final sales; risks associated with successful implementation of multiple integrated software products and other product functionality risks; risks associated with integrating acquisitions and changes in circumstances and plans associated therewith, including, among other risks, changes in plans related to product and services integrations, product and services plans and sales strategies; sales and marketing execution risks; execution risks around new product development and introductions and innovation; litigation and disputes and the potential cost, distraction and damage to sales and reputation caused thereby or by other factors; cybersecurity threats, breaches and other disruptions; market acceptance of new products and services; the ability to attract and retain personnel; changes in strategy; risks associated with management of growth; lengthy sales and implementation cycles, particularly in larger organizations; technological changes that make our products and services less competitive; risks associated with the adoption of, and demand for, our products and services in general and by specific customer segments, including those caused by the COVID-19 pandemic; competition and pricing pressure; product inventory shortages for any reason, including those caused by the COVID-19 pandemic; risks associated with business disruption caused by natural disasters and health emergencies such as earthquakes, fires, power outages, typhoons, floods, health epidemics and viruses such as the COVID-19 pandemic, and by manmade events such as civil unrest, labor disruption, international trade disputes, international conflicts, terrorism, wars, and critical infrastructure attacks; tariffs, trade disputes and other trade barriers, and negative impact on sales based on geo-political dynamics and disputes and protectionist policies; any political and government disruption around the world, including the impact of any future shutdowns of the U.S. government; and the other risk factors set forth from time to time in our most recent Annual Report on Form 10-K, our most recent Quarterly Report on Form 10-Q and our other filings with the Securities and Exchange Commission (SEC), copies of which are available free of charge at the SEC's website at www.sec.gov or upon request from our investor relations department. All forward-looking statements herein reflect our opinions only as of the date of this release, and we undertake no obligation, and expressly disclaim any obligation, to update forward-looking statements herein in light of new information or future events.

COVID-19 Impact

While the broader implications of the COVID-19 pandemic on our employees and overall financial performance remain uncertain, we have seen certain impacts on our business and operations, results of operations, financial condition, cash flows, liquidity and capital and financial resources. Going forward, the situation is uncertain, rapidly changing and hard to predict, and the COVID-19 pandemic may have a material negative impact on our future periods, including our results for the three months ending June 30, 2021, our annual results for 2021, and beyond. To highlight the uncertainty remaining for the three month period ending June 30, 2021, it should be noted that, due to customer buying patterns and the efforts of our sales force and channel partners to meet or exceed quarterly quotas, we have historically received a substantial portion of each quarter's sales orders and generated a substantial portion of each quarter's billings and revenue during the last two weeks of the quarter. If we experience significant changes in our billings growth rates, it will impact product revenue in the current quarter and FortiGuard and FortiCare service revenues in subsequent quarters, as we sell annual and multi-year service contracts that are recognized ratably over the contractual service term. In addition, the broader implications of the pandemic on our business and operations and our financial results, including the extent to which the effects of the pandemic will impact future results and growth in the cybersecurity industry, remain uncertain. The duration and severity of the economic downturn from the pandemic may negatively impact our business and operations, results of operations, financial condition, cash flows, liquidity and capital and financial resources in a material way. As a result, the effects of the pandemic may not be fully reflected in our results of operations until future periods.

Non-GAAP Financial Measures

We have provided in this release financial information that has not been prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP). These non-GAAP financial and liquidity measures are not based on any standardized methodology prescribed by GAAP and are not necessarily comparable to similar measures presented by other companies. We use these non-GAAP financial measures internally in analyzing our financial results and believe they are useful to investors, as a supplement to GAAP measures, in evaluating our ongoing operational performance. We believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing our financial results with peer companies, many of which present similar non-GAAP financial measures to investors.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures provided in the financial statement tables below.

Billings (non-GAAP). We define billings as revenue recognized in accordance with GAAP plus the change in deferred revenue from the beginning to the end of the period, less any deferred revenue balances acquired from business combination(s) during the period. We consider billings to be a useful metric for management and investors because billings drive current and future revenue, which is an important indicator of the health and viability of our business. There are a number of limitations related to the use of billings instead of GAAP revenue. First, billings include amounts that have not yet been recognized as revenue and are impacted by the term of security and support agreements. Second, we may calculate billings in a manner that is different from peer companies that report similar financial measures. Management accounts for these limitations by providing specific information regarding GAAP revenue and evaluating billings together with GAAP revenue.

Free cash flow (non-GAAP). We define free cash flow as net cash provided by operating activities minus purchases of property and equipment and excluding any significant non-recurring items, such as proceeds from intellectual property matter. We believe free cash flow to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by the business that, after capital expenditures and net of proceeds from intellectual property matter, can be used for strategic opportunities, including repurchasing outstanding common stock, investing in our business, making strategic acquisitions and strengthening the balance sheet. A limitation of using free cash flow rather than the GAAP measures of cash provided by or used in operating activities, investing activities, and financing activities is that free cash flow does not represent the total increase or decrease in the cash and cash equivalents balance for the period because it excludes cash flows from significant non-recurring items, such as proceeds from intellectual property matter, investing activities other than capital expenditures and cash flows from financing activities. Management accounts for this limitation by providing information about our capital expenditures and other investing and financing activities on the face of the cash flow statement and under the caption "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources" in our most recent Quarterly Report on Form 10-Q and Annual Report on Form 10-K and by presenting cash flows from investing and financing activities in our reconciliation of free cash flow. In addition, it is important to note that other companies, including companies in our industry, may not use free cash flow, may calculate free cash flow in a different manner than we do or may use other financial measures to evaluate their performance, all of which could reduce the usefulness of free cash flow as a comparative measure.

Non-GAAP operating income and operating margin. We define non-GAAP operating income as operating income plus stock-based compensation, impairment and amortization of acquired intangible assets, less gain on intellectual property matter and, when applicable, other significant non-recurring items in a given quarter, such as non-recurring gains or losses on litigation-related matters. Non-GAAP operating margin is defined as non-GAAP operating income divided by GAAP revenue. We consider these non-GAAP financial measures to be useful metrics for management and investors because they exclude the items noted above so that our management and investors can compare our recurring core business operating results over multiple periods. There are a number of limitations related to the use of non-GAAP operating income instead of operating income calculated in accordance with GAAP. First, non-GAAP operating income excludes the items noted above. Second, the components of the costs that we exclude from our calculation of non-GAAP operating income may differ from the components that peer companies exclude when they report their non-GAAP results of operations. Management accounts for these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP operating income and evaluating non-GAAP operating income together with operating income calculated in accordance with GAAP.

Non-GAAP net income and diluted net income per share. We define non-GAAP net income as net income or loss plus the items noted above under non-GAAP operating income and operating margin. In addition, we adjust non-GAAP net income and diluted net income per share for gains or losses on investments in privately held companies and a tax adjustment required for an effective tax rate on a non-GAAP basis, which differs from the GAAP effective tax rate. We define non-GAAP diluted net income per share as non-GAAP net income divided by the non-GAAP diluted weighted-average shares outstanding. We consider these non-GAAP financial measures to be useful metrics for management and investors for the same reasons that we use non-GAAP operating income and non-GAAP operating margin. However, in order to provide a more complete picture of our recurring core business operating results, we include in non-GAAP net income and non-GAAP diluted net income per share, the tax adjustment required resulting in an effective tax rate on a non-GAAP basis, which often differs from the GAAP tax rate. We believe the non-GAAP effective tax rates we use are reasonable estimates of normalized tax rates for our current and prior fiscal years under our global operating structure. The same limitations described above regarding our use of non-GAAP operating income and non-GAAP operating margin apply to our use of non-GAAP net income and non-GAAP diluted net income per share. We account for these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP net income and non-GAAP diluted net income per share and evaluating non-GAAP net income and non-GAAP diluted net income per share together with net income or loss and diluted net income per share calculated in accordance with GAAP.
