SAN JOSE, Calif., May 26, 2022 (GLOBE NEWSWIRE) -- Zscaler, Inc. (Nasdaq: ZS), the leader in cloud security, today announced financial results for its third quarter of fiscal year 2022, ended April 30, 2022.

"Enterprises continue to consolidate point products in favor of our integrated Zero Trust security platform, resulting in larger, multi-year commitments to Zscaler. We delivered 63% revenue growth and 54% billings growth, while also generating a strong free cash flow margin of 15% for the third quarter. As a result of increasing demand, we are also raising our fiscal year guidance on all financial metrics,” said Jay Chaudhry, Chairman and CEO of Zscaler. “Demanding enterprises look to Zscaler as their strategic partner of choice in their Zero Trust journey, as the world races towards network and security transformation.”

• Released annual Zscaler ThreatLabZ research revealing up to a 400% increase in Phishing-as-a-Service as the key source of attacks across critical industries and consumers globally, underscoring the urgency for businesses and users to adopt a Zero Trust security model.
  
  
• Invested in Zscaler’s hypergrowth strategy with the appointment of Brendan Castle, Chief People Officer. Bringing 30 years of experience from organizations like Google and Citibank, Castle will lead the expansion of Zscaler's global People and Culture organization, including talent acquisition, learning and development, internal business partners, diversity, equity and inclusion, and our workplace experience.

Financial Outlook

For the fourth quarter of fiscal 2022, we expect:

• Total revenue of $304 million to $306 million
• Non-GAAP income from operations of $33 million to $34 million 
• Non-GAAP net income per share of approximately $0.20 to $0.21, assuming approximately 146 million to 147 million common shares outstanding
  

For the full year fiscal 2022, we expect:

• Total revenue of approximately $1.078 billion
• Calculated billings of $1.425 billion to $1.430 billion
• Non-GAAP income from operations of $106 million to $108 million
• Non-GAAP net income per share of $0.64 to $0.65, assuming approximately 147 million to 148 million common shares outstanding

These statements are forward-looking and actual results may differ materially. Refer to the Forward-Looking Statements safe harbor below for information on the factors that could cause our actual results to differ materially from these forward-looking statements.

Guidance for non-GAAP income from operations excludes stock-based compensation expense and related employer payroll taxes, amortization expense of acquired intangible assets, asset impairment related to facility exit, amortization of debt discount and issuance costs and income tax effects generated by intangible assets acquired in business acquisitions. Guidance for non-GAAP net income per share includes the anti-dilutive impact of the capped call transactions entered into in connection with our convertible senior notes. We have not reconciled our expectations to non-GAAP income from operations and non-GAAP net income per share to their most directly comparable GAAP measures because certain items are out of our control or cannot be reasonably predicted. Accordingly, a reconciliation for the guidance for non-GAAP income from operations and non-GAAP net income per share is not available without unreasonable effort.

___________
⁽¹⁾ Consists of asset impairment charges related to the relocation of our corporate headquarters.

⁽²⁾ We use our GAAP provision for income taxes for purposes of determining our non-GAAP income tax expense. The difference between our GAAP and non-GAAP income tax expense represents the effects of stock-based compensation expense recognized in foreign jurisdictions and any income tax benefits associated with business combinations. The income tax benefit related to stock-based compensation expense included in the GAAP provision for income taxes was not material for all periods presented. In the fiscal quarter ended April 30, 2022, we recorded a tax benefit of $1.6 million associated with a refund of certain foreign withholding taxes relating to the prior fiscal year. In the fiscal quarter ended January 31, 2022, we recorded a tax benefit of $0.4 million generated by intangible assets acquired in a business acquisition.

⁽³⁾ The sum of the fully diluted earnings per share impact of individual reconciling items may not total to fully diluted Non-GAAP net income per share due to the weighted-average shares used in computing the GAAP net loss per share differs from the weighted-average shares used in computing the Non-GAAP net income per share and due to rounding of the individual reconciling items. The GAAP net loss per share calculation uses a lower share count as it excludes potentially dilutive shares, which are included in calculating the non-GAAP net income per share.

⁽⁴⁾ We exclude the in-the-money portion of our convertible senior notes for non-GAAP weighted-average diluted shares as they are covered by our capped call transactions. Our outstanding capped call transactions are antidilutive under GAAP, but are expected to mitigate the dilutive effect of our convertible notes and therefore are included in the calculations of non-GAAP diluted shares outstanding.

ZSCALER, INC.
Explanation of Non-GAAP Financial Measures

In addition to our results determined in accordance with generally accepted accounting principles in the United States of America (GAAP), we believe the following non-GAAP measures are useful in evaluating our operating performance. We use the following non-GAAP financial information to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. In particular, free cash flow is not a substitute for cash provided by operating activities. Additionally, the utility of free cash flow as a measure of our liquidity is further limited as it does not represent the total increase or decrease in our cash balance for a given period. In addition, other companies, including companies in our industry, may calculate similarly-titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. A reconciliation of our historical non-GAAP financial measures to their most directly comparable financial measures stated in accordance with GAAP has been included in this press release. Investors are cautioned that there are a number of limitations associated with the use of non-GAAP financial measures and key metrics as analytical tools. Investors are encouraged to review these reconciliations, and not to rely on any single financial measure to evaluate our business.

Expenses Excluded from Non-GAAP Measures

Stock-based compensation expense is excluded primarily because it is a non-cash expense that management believes is not reflective of our ongoing operational performance. Employer payroll taxes related to stock-based compensation, which is a cash expense, are excluded because these are tied to the timing and size of the exercise or vesting of the underlying equity awards and the price of our common stock at the time of vesting or exercise, which may vary from period to period independent of the operating performance of our business. Amortization expense of intangible assets acquired in business acquisitions and related income tax effects, if applicable, are excluded because these are considered by management to be outside of our core business operating performance. Asset impairments related to facility exit costs are excluded because such charges are not reflective of our ongoing operational performance. Amortization of debt discount and issuance costs from our convertible senior notes are excluded because these are non-cash expenses and are not reflective of our ongoing operational performance. We estimate the tax effect of these items on our non-GAAP results and may adjust our GAAP provision for income taxes, if such effects have a material impact to our non-GAAP results.

Non-GAAP Financial Measures

Non-GAAP Gross Profit and Non-GAAP Gross Margin. We define non-GAAP gross profit as GAAP gross profit excluding stock-based compensation expense and related employer payroll taxes and amortization expense of acquired intangible assets. We define non-GAAP gross margin as non-GAAP gross profit as a percentage of revenue.

Non-GAAP Income from Operations and Non-GAAP Operating Margin. We define non-GAAP income from operations as GAAP loss from operations excluding stock-based compensation expense and related employer payroll taxes, amortization expense of acquired intangible assets, asset impairment related to facility exit and certain litigation-related expenses. We define non-GAAP operating margin as non-GAAP income from operations as a percentage of revenue.

Non-GAAP Net Income per Share, Diluted. We define non-GAAP net income as GAAP net loss excluding stock-based compensation expense and related employer payroll taxes, amortization expense of acquired intangible assets, asset impairment related to facility exit, amortization of debt discount and issuance costs, income tax effects generated by the effects of stock-based compensation expense recognized in foreign jurisdictions, any income tax benefits associated with business combinations and refunds of certain foreign withholding taxes related to prior fiscal periods. We define non-GAAP net income per share, diluted, as non-GAAP net income divided by the weighted-average diluted shares outstanding, which includes the effect of potentially diluted common stock equivalents outstanding during the period and the antidilutive impact of the capped call transactions entered into in connection with our convertible senior notes.

Calculated Billings. We define calculated billings as total revenue plus the change in deferred revenue in a period. Calculated billings in any particular period aims to reflect amounts invoiced for subscriptions to access our cloud platform, together with related support services for our new and existing customers. We typically invoice our customers annually in advance, and to a lesser extent quarterly in advance, monthly in advance or multi-year in advance.

Free Cash Flow and Free Cash Flow Margin. We define free cash flow as net cash provided by operating activities less purchases of property, equipment and other assets and capitalized internal-use software. We define free cash flow margin as free cash flow divided by revenue. We believe that free cash flow and free cash flow margin are meaningful indicators of liquidity information to management and investors about the amount of cash generated from our operations that, after the investments in property, equipment and other assets and capitalized internal-use software, can be used for strategic initiatives.
