SUNNYVALE, Calif., Oct. 25, 2018 (GLOBE NEWSWIRE) -- Proofpoint, Inc. (NASDAQ: PFPT), a leading next-generation security and compliance company, today announced financial results for the third quarter ended September 30, 2018.

“The third quarter marked another compelling example of our team’s disciplined execution and strong customer focus,” stated Gary Steele, chief executive officer of Proofpoint. “We were pleased with our quarterly results, which were again driven by the rapidly evolving threat landscape, the ongoing shift to the cloud, and continued high demand for our advanced threat and compliance capabilities. Given these ongoing trends and our proven ability to identify and block advanced threats, I believe that we are well-positioned to continue to gain share and deliver attractive returns for our shareholders.” 

Third Quarter 2018 Financial Highlights

  • Revenue: Total revenue for the third quarter of 2018 was $184.2 million, an increase of 37%, compared to $134.7 million for the third quarter of 2017.
     
  • Billings: Total billings for the third quarter of 2018 were $221.4 million, an increase of 33%, compared to $166.5 million for the third quarter of 2017.

  • Operating Income (Loss): GAAP operating loss for the third quarter of 2018 was $(26.6) million compared to a loss of $(13.6) million for the third quarter of 2017.  Non-GAAP operating income for the third quarter of 2018 was $22.7 million compared to $15.8 million for the third quarter of 2017. 
  • Net Income (Loss): GAAP net loss for the third quarter of 2018 was $(36.1) million, or $(0.69) per share, based on 52.2 million weighted average shares outstanding.  This compares to a GAAP net loss of $(19.5) million, or $(0.44) per share, based on 44.4 million weighted average shares outstanding for the third quarter of 2017.

  • Cash and Cash Flow: As of September 30, 2018, Proofpoint had cash, cash equivalents, and short term investments of $190.4 million.  The company generated $64.7 million in cash flow from operations for the third quarter of 2018 compared to $44.2 million during the third quarter of 2017.  The company’s free cash flow for the quarter was $58.2 million compared to $32.3 million for the third quarter of 2017.    

“We were pleased with our ability to exceed expectations during the third quarter, highlighted by revenue and billings growth of 37% and 33%, respectively, as well as another quarter of strong free cash flow generation,” stated Paul Auvil, chief financial officer of Proofpoint. “The investments we’re making in our team, and in expanding our product portfolio, represent strong competitive differentiators and further extend our ability to generate attractive top-line growth coupled with strong free cash flow margins.” 

A reconciliation of GAAP to non-GAAP financial measures has been provided in the financial tables included in this press release.  An explanation of these measures and how they are calculated are also included below under the heading “Non-GAAP Financial Measures.”

Computational Guidance on Earnings Per Share Estimates

Accounting principles require that EPS be computed based on the weighted average shares outstanding ("basic"), and also assuming the issuance of potentially issuable shares (such as those subject to stock options, convertible notes, etc.) if those potentially issuable shares would reduce EPS ("diluted").

The number of shares related to options and similar instruments included in diluted EPS is based on the "Treasury Stock Method" prescribed in Financial Accounting Standards Board ("FASB") ASC Topic 260, Earnings Per Share ("FASB ASC Topic 260"). This method assumes a theoretical repurchase of shares using the proceeds of the respective stock option exercise at a price equal to the issuer's average stock price during the related earnings period. Accordingly, the number of shares includable in the calculation of diluted EPS in respect of stock options and similar instruments is dependent on this average stock price and will increase as the average stock price increases.

The number of shares includable in the calculation of diluted EPS in respect of convertible senior notes is based on the "If Converted" method prescribed in FASB ASC Topic 260. This method assumes the conversion or exchange of these securities for shares of common stock. In determining if convertible securities are dilutive, the interest savings (net of tax) subsequent to an assumed conversion are added back to net earnings. The shares related to a convertible security are included in diluted EPS only if EPS as otherwise calculated is greater than the interest savings, net of tax, divided by the shares issuable upon exercise or conversion of the instrument. Accordingly, the calculation of diluted EPS for these instruments is dependent on the level of net earnings. Each series of convertible securities is considered individually and in sequence, starting with the series having the lowest incremental earnings per share, to determine if its effect is dilutive or anti-dilutive.

Non-GAAP Financial Measures

We have provided in this release financial information that has not been prepared in accordance with GAAP. 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 other companies in our industry, 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 below. As previously mentioned, a reconciliation of our non-GAAP financial measures to their most directly comparable GAAP measures has been provided in the financial statement tables included below in this press release.

Non-GAAP gross profit and gross margin. We define non-GAAP gross profit as GAAP gross profit, adjusted to exclude stock-based compensation expense and the amortization of intangibles associated with acquisitions. We define non-GAAP gross margin as non-GAAP gross profit divided by GAAP revenue. We consider these non-GAAP financial measures to be useful metrics for management and investors because they exclude the effect of non-cash charges that can fluctuate for Proofpoint, based on timing of equity award grants and the size, timing and purchase price allocation of acquisitions 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 gross profit and non-GAAP gross margin versus gross profit and gross margin, in each case, calculated in accordance with GAAP. For example, stock-based compensation has been and will continue to be for the foreseeable future a significant recurring expense in our business. Stock-based compensation is an important part of our employees' compensation and impacts their performance. In addition, the components of the costs that we exclude in our calculation of non-GAAP gross profit and non-GAAP gross margin may differ from the components that our peer companies exclude when they report their non-GAAP results.  Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP gross profit and non-GAAP gross margin and evaluating non-GAAP gross profit and non-GAAP gross margin together with gross profit and gross margin calculated in accordance with GAAP.

Non-GAAP operating loss. We define non-GAAP operating loss as operating loss, adjusted to exclude stock-based compensation expense and the amortization of intangibles and costs associated with acquisitions and litigation. Costs associated with acquisitions include legal, accounting, and other professional fees, as well as changes in the fair value of contingent consideration obligations. We consider this non-GAAP financial measure to be a useful metric for management and investors because they exclude the effect of stock-based compensation expense and the amortization of intangibles and costs associated with acquisitions and litigation 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 loss versus operating loss calculated in accordance with GAAP. For example, as noted above, non-GAAP operating loss excludes stock-based compensation expense. In addition, the components of the costs that we exclude in our calculation of non-GAAP operating loss may differ from the components that our peer companies exclude when they report their non-GAAP results of operations, and some of these items are cash-based. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP operating loss and evaluating non-GAAP operating loss together with operating loss calculated in accordance with GAAP.

Non-GAAP net loss. We define non-GAAP net loss as net loss, adjusted to exclude stock-based compensation expense, amortization of intangibles, costs associated with acquisitions and litigation, non-cash interest expense related to the convertible debt discount and issuance costs for the convertible debt offering, loss on conversion of convertible debt, and tax effects associated with these items. We consider this non-GAAP financial measure to be a useful metric for management and investors for the same reasons that we use non-GAAP operating loss. However, in order to provide a complete picture of our recurring core business operating results, we also exclude from non-GAAP net loss the tax effects associated with stock-based compensation and the amortization of intangibles and costs associated with acquisitions and litigation, non-cash interest expense related to the convertible debt discount and issuance costs for the convertible debt offering, and loss on conversion of convertible debt.

In order to provide a complete picture of our recurring core business operating results, we also compute the tax effect of the adjustments used in determining our non-GAAP results by calculating an adjusted tax provision which considers the current and deferred tax impact of the adjustments.  The adjusted tax provision reflects all of the relevant impacts of the adjustments, inclusive of those items that have an impact to the effective tax rate, current provision and deferred provision.  As a result of the varying impacts of each item, the effective tax rate for the adjusted tax provision will vary period over period as compared to the GAAP tax provision. The adjusted tax provision is then compared to the GAAP tax provision, and the difference is reflected as “income tax benefit (expense)” in the reconciliation between GAAP net loss/income and Non-GAAP net loss/income.

Billings. We define billings as revenue recognized plus the change in deferred revenue and customer prepayments less change in unbilled accounts receivable from the beginning to the end of the period, but excluding additions to deferred revenue from acquisitions. Customer prepayments represent billed amounts for which the contract can be terminated and the customer has a right of refund. Unbilled accounts receivable represent amounts for which the Company has recognized revenue, pursuant to its revenue recognition policy, for subscription software already delivered and professional services already performed, but billed in arrears and for which the Company believes it has an unconditional right to payment. We consider billings to be a useful metric for management and investors because billings drive deferred revenue, which is an important indicator of the health and visibility of our business, and has historically represented a majority of the quarterly revenue that we recognize. There are a number of limitations related to the use of billings versus revenue calculated in accordance with GAAP. Billings include amounts that have not yet been recognized as revenue, but exclude additions to deferred revenue from acquisitions. We may also calculate billings in a manner that is different from other companies that report similar financial measures. Management compensates for these limitations by providing specific information regarding GAAP revenue and evaluating billings together with revenues calculated in accordance with GAAP.

Free cash flow. We define free cash flow as net cash provided by operating activities minus capital expenditures. We consider 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 the acquisition of property and equipment, can be used for strategic opportunities, including investing in our business, making strategic acquisitions, and strengthening the balance sheet. Analysis of free cash flow facilitates management's comparisons of our operating results to competitors' operating results. A limitation of using free cash flow versus the GAAP measure of net cash provided by operating activities as a means for evaluating our company is that free cash flow does not represent the total increase or decrease in the cash balance from operations for the period because it excludes cash used for capital expenditures during the period. Management compensates for this limitation by providing information about our capital expenditures on the face of the cash flow statement and in the "Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources" section of our quarterly and annual reports filed with the SEC.

(1) Due to the full valuation allowance on the Company's U.S. deferred tax assets, there were no tax effects associated with the non-GAAP adjustments for stock-based compensation expense, costs associated with acquisitions and litigations, loss on conversion of convertible notes, and non-cash interest expense related to the debt discount and issuance costs for the convertible notes. Only GAAP deferred tax expenses or benefits related to the amortization of intangibles and deferred tax benefits related to changes in the Company's valuation allowance resulting from business acquisitions were excluded from the non-GAAP income tax expense. The Non-GAAP income tax for the nine months ended September 30, 2018, excluded $14,725 of deferred tax benefits related to a reduction in the Company’s deferred tax valuation allowance resulting from the Wombat Acquisition.
 
(2) The Company uses the if-converted method to compute diluted earnings per share with respect to its convertible senior notes. There was no add-back of interest expense or additional dilutive shares related to the convertible senior notes where the effect was anti-dilutive.
 
(3) The Company uses the treasury method to compute the dilutive effect of employee equity incentive plan awards.
