CAMPBELL, Calif., Jan. 9, 2017 – Barracuda Networks, Inc. (NYSE: CUDA), a leading provider of cloud-enabled security and data protection solutions, today announced results for its third quarter fiscal 2017 that ended Nov. 30, 2016.
"Barracuda delivered a strong third quarter with core product billings outpacing our expectations, driven in part by increasing customer adoption of our cloud-based security and data protection solutions. We continue to execute on our strategy to capitalize on market trends as more customers utilize our solutions as they move applications and workloads to the cloud," said BJ Jenkins, president and CEO. "The threat landscape is complex and constantly evolving. As threats become more sophisticated, security remains a top priority for customers. We continue to drive innovation and deliver easy-to-use products that address our customers’ most pressing security needs across multiple threat vectors, including email, networks, web applications and mobile devices."

Forward-Looking Statements
This announcement contains forward-looking statements related to our strategy and core products, the adoption of our cloud and security and data protection products, potential benefits from newly launched and updated products to customers and partners, and potential results from new initiatives and new channels and go-to-market strategies that involve risks and uncertainties, including statements regarding our expectations regarding financial performance, and the potential impact of our new and updated products. Actual results could differ materially from those projected in the forward-looking statements as a result of certain risk factors, including, but not limited to: fluctuations in demand for our products and services; a highly competitive and evolving business environment for network security and storage solutions; the company’s effectiveness in controlling expenses and timing of infrastructure costs; the effects of significant developments in IT infrastructure deployments, particularly cloud computing; the impact of foreign currency fluctuations; the possibility that we might experience delays in the development of new technology and products; risks related to recent or future acquisitions; customer response to our new technology and products; risks related to pending or future litigation and regulatory matters; a dependency on third parties for certain components of our products and the impact of changes in our management team. The company undertakes no obligation to update the forward-looking information in this release. More information about potential factors that could affect our business and financial results is included in our filings with the Securities and Exchange Commission, including, without limitation, under the captions: "Management’s Discussion and Analysis of Financial Condition and Results of Operations," and "Risk Factors," which are on file with the Securities and Exchange Commission.
Non-GAAP Financial Measures
Barracuda provides all financial information required in accordance with generally accepted accounting principles (GAAP). To supplement our consolidated financial statements presented in accordance with GAAP, we are also providing with this press release and on our conference call with non-GAAP net income, non-GAAP operating income, non-GAAP gross margins, non-GAAP operating expenses, adjusted EBITDA and free cash flow. In preparing our non-GAAP information, we have excluded certain amounts as set forth in the attached financial tables and footnotes. We believe that excluding these items provides both management and investors with additional insight into our current operations and the trends affecting the company. In particular, management finds it useful to exclude these items in order to more readily correlate the company's operating activities with the company's ability to generate cash from operations. Accordingly, management uses these non-GAAP measures, along with the comparable GAAP information, in evaluating our historical performance and in planning our future business activities. Please note that our non-GAAP measures may be different than those used by other companies. The additional non-GAAP financial information we present should be considered in conjunction with, and not as a substitute for, our financial information presented in accordance with GAAP. We have provided reconciliations of these non-GAAP measures to their comparable GAAP measures for the periods presented in this release, which exclude certain amounts as set forth in the attached financial tables and footnotes for these periods. These measures should only be used to evaluate the company's results of operations in conjunction with the corresponding GAAP measures for comparable financial information and understanding of the company's ongoing performance as a business. Barracuda uses both GAAP and non-GAAP measures to evaluate and manage its operations.
Beginning in the third quarter of fiscal 2017, we modified our reporting practices to comply with recent SEC interpretations on the use of non-GAAP measures. As a result, we have modified our historical presentation of adjusted EBITDA and free cash flow. We will no longer adjust for changes in deferred revenue and associated deferred costs in our calculation of adjusted





EBITDA, and for free cash flow we will not adjust for the cash payment impact of acquisition and other charges. Prior period information has been recast to conform to the adjusted calculations.
Forward-looking non-GAAP financial measures included in Barracuda’s guidance exclude amortization of intangible assets, stock-based compensation expense, acquisition and other charges, income tax effects related to such exclusions and other expense (income) adjustments. Barracuda does not provide reconciliations of its forward-looking non-GAAP financial measures to the corresponding GAAP measures due to the high variability of, and difficulty in making accurate forecasts and projections with respect to, the items excluded from these non-GAAP financial measures. In particular, stock-based compensation and related taxes are impacted by the company’s future hiring and retention needs, as well as the future fair market value of its common stock, all of which is difficult to predict and subject to constant change. Accordingly, reconciliations of its forward-looking non-GAAP financial measures to the corresponding GAAP measures are not available without unreasonable effort. The actual amounts of these excluded items will have a significant impact on the company’s GAAP operating income (loss) and net income (loss) per diluted share.

(1) 
Amortization of Intangible Assets. We provide non-GAAP information which excludes expenses for the amortization of intangible assets, as well as certain losses on disposal and impairment of such assets, that primarily relate to purchased intangible assets associated with our acquisitions. We believe that eliminating this expense from our non-GAAP measures is useful to investors because the amortization of intangible assets can be inconsistent in amount and frequency and is significantly impacted by the timing and magnitude of our acquisition transactions, which also vary in frequency from period to period. Accordingly, we analyze the performance of our operations in each period without regard to such expenses.
(2) 
Depreciation Expense. We provide non-GAAP information which excludes depreciation expense related to the amortization of property and equipment, as well as certain losses from disposal of such assets. We believe that eliminating this expense from our non-GAAP measures is useful to investors because the acquisition of property and equipment, and the corresponding depreciation expense, can be inconsistent in amount and can vary from period to period.
(3) 
Stock-Based Compensation Expense. We provide non-GAAP information which excludes expenses for stock-based compensation. We believe the exclusion of stock-based compensation expense allows for financial results that are more indicative of our continuing operations. We also believe that the exclusion of stock-based compensation expense provides for a better comparison of our operating results to prior periods and to our peer companies as the calculations of stock-based compensation vary from period to period and company to company due to different valuation methodologies, subjective assumptions and the variety of award types.
(4) 
Acquisition and Other Charges. We exclude certain expense items resulting from acquisitions and other charges, which we believe are non-recurring, infrequent and/or unusual in nature, can vary significantly in amount and frequency and are unrelated to our ongoing operating performance. We believe that adjusting for these charges allows us to better compare results from period to period in order to assess the ongoing operating results of our business. The charges include: (i) acquisition-related expenses for legal, accounting, and other professional fees, integration costs, fair value remeasurements of contingent consideration obligations and contingent consideration payments made under the terms of acquisition agreements, and (ii) other costs that are non-recurring, infrequent and/or unusual in nature, such as expenses incurred in connection with litigation, export compliance, intellectual property settlement and other matters.
(5) 
Income Tax Effect of Non-GAAP Exclusions. We believe providing financial information with and without the income tax effect of excluding items related to our non-GAAP financial measures provide our management and users of the financial statements with better clarity regarding the ongoing performance and future liquidity of our business. Excluded items include, but are not limited to: (i) amortization expense of intangible assets, (ii) stock-based compensation expense, (iii) acquisition and other charges, and (iv) quarterly changes to the valuation allowance previously established.
(6) 
Other Expense (Income) Adjustments. We provide non-GAAP information that excludes the effect of certain other income and losses. These adjustments consist of realized gains and losses from the sale of marketable securities and foreign currency remeasurement gains and losses. For all non-functional currency account balances, the remeasurement of such balances to the functional currency will result in either a foreign exchange gain or a loss which is recorded in other income (expense), net. We believe that eliminating these items from our non-GAAP measures is useful to investors, because these items can be inconsistent in amount and can vary from period to period.
(7) 
Non-GAAP Diluted Earnings Per Share. We provide non-GAAP diluted earnings per share. Non-GAAP diluted earnings per share is calculated based on our non-GAAP net income divided by the weighted-average diluted shares outstanding for the period.

Adjusted EBITDA. Beginning in the third quarter of fiscal 2017, we modified our reporting practices to comply with recent SEC interpretations on the use of non-GAAP measures. As a result, we have modified our historical presentation of adjusted EBITDA and will no longer adjust for changes in deferred revenue and associated deferred costs in our calculation of adjusted EBITDA. These changes do not impact our current and historical presentation of GAAP results. Prior period information has been recast to conform to the adjusted calculation. We define adjusted EBITDA as net income (loss) plus non-cash and non-operating charges which include: (i) other expense (income), net, (ii) provision for (benefit from) income taxes, (iii) acquisition and other charges, (iv) stock-based compensation expense, (v) amortization of intangible assets, including certain losses on disposal and impairment of intangible assets, and (vi) depreciation expense, including certain losses on disposal of fixed assets. We believe adjusted EBITDA provides an indication of profitability from our operations, and provides a consistent measure of our performance from period to period.
In addition to adjusted EBITDA, we also monitor the changes in deferred revenue and associated deferred costs to facilitate a supplemental comparison of our performance from period to period as set forth in the table below (in thousands):

Free Cash Flow. Beginning in the third quarter of fiscal 2017, we modified our reporting practices to comply with recent SEC interpretations on the use of non-GAAP measures. As a result, we have modified our historical presentation of adjusted free cash flow and will no longer adjust free cash flow for the cash payment impact of acquisition and other charges. These changes do not impact our current and historical presentation of GAAP results. Prior period information has been recast to conform to the adjusted calculation. We define free cash flow as cash flows from operating activities less the purchases of property and equipment. We believe free cash flow is an important liquidity measure that reflects the cash generated by the business after the purchase of property and equipment that can then be used for, among other things, strategic acquisitions, investments in the business and funding ongoing operations.

Gross Billings. We define gross billings as total revenue plus the change in deferred revenue and other adjustments, which primarily consist of returns and reserves with respect to the 30-day right of return we provide to customers, as well as rebates for certain channel partner activities. We believe that gross billings provide insight into the sales of our solutions and performance of our business. The deferred revenue balances for the prior fiscal year's comparable periods exclude amounts related to the deferred revenue assumed in connection with our acquisition of C2C Systems Limited, which closed in the second quarter of fiscal 2015.
(2) 
In order to determine how our business performed exclusive of the effect of foreign currency fluctuations, we compare the percentage change in our gross billings from one period to another using a constant currency. To present this gross billings information, the current and comparative prior period results for entities that operate in other than U.S. dollars are converted into U.S. dollars at constant exchange rates. For example, the rates in effect at November 30, 2015, which was the last day of our prior fiscal year’s comparable quarter, were used to convert current and comparable prior period gross billings rather than the actual exchange rates in effect during the respective period.
