Financial Outlook

Mimecast is providing guidance for the third quarter and fiscal year 2022. Our guidance is based on exchange rates as of October 25, 2021.

Third Quarter 2022 Guidance:

  • For the third quarter of 2022, revenue is expected to be in the range of $149.2 million to $150.7 million and constant currency revenue growth is expected to be in the range of 13% to 14%.
  • Foreign exchange rate fluctuations are positively impacting this guidance by an estimated $2.7 million compared to the rates in effect in the prior year.
  • Adjusted EBITDA for the third quarter is expected to be in the range of $41.0 million to $42.0 million.
  • Operating cash flow for the third quarter is expected to be in the range of $40.5 million to $41.5 million.
  • Free cash flow for the third quarter is expected to be in the range of $33.0 million to $34.0 million.

Fiscal Year 2022 Guidance:

  • For the full year 2022, revenue is expected to be in the range of $589.9 million to $593.6 million and constant currency revenue growth is expected to be in the range of 14% to 15%.
  • Foreign exchange rate fluctuations are positively impacting this guidance by an estimated $17.5 million compared to the rates in effect in the prior year.
  • Full year 2022 Adjusted EBITDA is expected to be between $164.2 million and $165.7 million.
  • Operating cash flow for the full year 2022 is expected to be in the range of $174.6 to $176.1 million.
  • Free cash flow for the full year 2022 is expected to be in the range of $136.1 million to $137.6 million.

GAAP net income is the most comparable GAAP measure to Adjusted EBITDA. Adjusted EBITDA differs from GAAP net income in that it excludes depreciation, amortization, disposals and impairment of long-lived assets, acquisition-related gains and expenses, litigation-related expenses, share-based compensation expense, restructuring expense, interest income and interest expense, the benefit from (provision for) income taxes and foreign exchange income (expense). Mimecast is unable to predict with reasonable certainty the ultimate outcome of these exclusions without unreasonable effort. Therefore, Mimecast has not provided guidance for GAAP net income or a reconciliation of forward-looking Adjusted EBITDA guidance to GAAP net income. The reconciliation between guided net cash provided by operating activities to guided free cash flow for the second quarter 2022 and fiscal year 2022 is provided in the financial tables included at the end of this press release. Revenue growth rate guidance is presented in constant currency reflecting the fact that global currency exchange rates in the multiple jurisdictions in which Mimecast operates are outside of the Company’s control.

The financial guidance provided above includes forward-looking statements within the meaning of U.S. securities laws. While the financial guidance considers the anticipated impact of the Company’s recent security incident and the global COVID-19 pandemic, the future effect of the security incident and the pandemic on Mimecast’s financial results is highly uncertain. Mimecast’s actual results may differ materially. See “Safe Harbor for Forward-Looking Statements” below.

Mimecast will host a conference call to discuss these financial results for investors and analysts at 8:00 am EDT (UTC-05:00) on November 2, 2021.

Non-GAAP Financial Measures

We have provided in this press 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 provided in the financial statement tables included below in this press release.

Revenue Constant Currency Growth Rate. We believe revenue constant currency growth rate is a key indicator of our performance as it measures how we are executing on our strategy exclusive of currency fluctuations, which are beyond our control. We calculate revenue constant currency growth rate by translating revenue from entities reporting in foreign currencies into U.S. dollars using the comparable foreign currency exchange rates from the prior fiscal period. To determine projected revenue growth rates on a constant currency basis for the third quarter and full year 2022, expected revenue from entities reporting in foreign currencies is translated into U.S. dollars using the comparable prior year period’s monthly average foreign currency exchange rates.

Non-GAAP gross profit and Non-GAAP gross profit percentage. We define non-GAAP gross profit as gross profit, adjusted to exclude: share-based compensation expense and amortization of acquired intangible assets. We define non-GAAP gross profit percentage 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 for share-based compensation expense and amortization of acquired intangible assets so that our management and investors can compare our recurring core business net results over multiple periods. There are a number of limitations related to the use of non-GAAP gross profit and non-GAAP gross profit percentage versus gross profit and gross profit percentage calculated in accordance with GAAP. For example, as noted above, non-GAAP gross profit and gross profit percentage excludes share-based compensation expense and amortization of acquired intangible assets. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP gross profit and non-GAAP gross profit percentage and evaluates non-GAAP gross profit and non-GAAP gross profit percentage together with gross profit and gross profit percentage calculated in accordance with GAAP.

Non-GAAP operating expenses and Non-GAAP income from operations. We provide investors with certain non-GAAP financial measures, including non-GAAP research and development expense, non-GAAP sales and marketing expense, non-GAAP general and administrative expense and non-GAAP income from operations (collectively the “non-GAAP operating financial measures”). These non-GAAP operating financial measures exclude the following, as applicable (as reflected in the reconciliation tables that follow): share-based compensation expense; amortization of acquired intangible assets; impairment of long-lived assets; restructuring expense; acquisition-related gains and expenses; and litigation-related expenses. We consider these non-GAAP operating financial measures to be useful metrics for management and investors because it excludes the effect of share-based compensation expense and certain “one-time” charges so that our management and investors can compare our recurring core business net results over multiple periods. There are a number of limitations related to the use of these non-GAAP operating financial measures versus the applicable financial measures calculated in accordance with GAAP. For example, as noted above, the non-GAAP operating financial measures exclude share-based compensation expense and certain “one-time” charges. In addition, the components of the costs that we exclude in our calculation of non-GAAP operating financial measures may differ from the components that our peer companies exclude when they report their non-GAAP results of operations. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP operating financial measures and evaluates non-GAAP operating financial measures together with the applicable financial measures calculated in accordance with GAAP. We use non-GAAP operating income as part of our overall assessment of our performance, to communicate with our board of directors concerning our financial performance, and for establishing incentive compensation metrics for executives and other senior employees.

Non-GAAP net income. We define non-GAAP net income as net income, adjusted to exclude: share-based compensation expense; amortization of acquired intangible assets; impairment of long-lived assets; restructuring expense; acquisition-related gains and expenses; litigation-related expenses; and the income tax effect of non-GAAP adjustments.

Starting April 1, 2021, we changed the calculation of our non-GAAP provision for income taxes by utilizing a long-term projected non-GAAP tax rate in accordance with the Securities and Exchange Commission’s Non-GAAP Financial Measures Compliance and Disclosure Interpretations (C&DI 102.11). We are utilizing a long-term projected non-GAAP tax rate as it will provide a consistent evaluation of our non-GAAP tax position between interim reporting periods.

In our computation of the long-term projected non-GAAP tax rate, we exclude the tax effect of adjustments to non-GAAP net income, as defined above.

The long-term projected non-GAAP tax rate may be subject to change and considers factors such as our current operating structure, geographical earnings mix, existing tax positions in various jurisdictions, current company strategy, and rapidly evolving legislation in major jurisdictions in which we operate. This adoption has no impact on our GAAP consolidated financial statements.

We consider non-GAAP net income to be a useful metric for management and investors because it excludes the effect of share-based compensation expense, certain “one-time” charges and related income tax effects so that our management and investors can compare our recurring core business net results over multiple periods. There are a number of limitations related to the use of non-GAAP net income versus net income calculated in accordance with GAAP. For example, as noted above, non-GAAP net income excludes share-based compensation expense, certain “one-time” charges and related income tax effects. In addition, the components of the costs that we exclude in our calculation of non-GAAP net income may differ from the components that our peer companies exclude when they report their non-GAAP results of operations. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from non-GAAP net income and evaluating non-GAAP net income together with net income calculated in accordance with GAAP.

Adjusted EBITDA and Adjusted EBITDA margin. We believe that Adjusted EBITDA and Adjusted EBITDA margin are key indicators of our operating results. We define Adjusted EBITDA as net income, adjusted to exclude: depreciation; amortization; disposals and impairment of long-lived assets; acquisition-related gains and expenses; litigation-related expenses; share-based compensation expense; restructuring expense; interest income and interest expense; the provision for income taxes; and foreign exchange income (expense). We define Adjusted EBITDA margin as Adjusted EBITDA over GAAP revenue in the period. We use Adjusted EBITDA as part of our overall assessment of our performance, for planning purposes, including the preparation of our annual operating budget, to evaluate the effectiveness of our business strategies, and to communicate with our board of directors concerning our financial performance.

Free cash flow. We believe free cash flow is 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, equipment and capitalized software, can be used for strategic opportunities, including investing in our business, and strengthening the balance sheet. Analysis of free cash flow facilitates management’s comparisons of our operating results to competitors’ operating results. We define free cash flow as net cash provided by operating activities minus purchases of property, equipment and capitalized software. 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 liquidity and capital resources discussion included in our annual and quarterly reports filed with the Securities and Exchange Commission.

Key Performance Indicators

In addition to traditional financial metrics, such as revenue and revenue growth trends, we monitor several other non-GAAP financial measures and non-financial metrics to help us evaluate growth trends, establish budgets, measure the effectiveness of our sales and marketing efforts and assess operational efficiencies. The key performance indicators that we monitor are as follows:

    Three months ended September 30,     Six months ended September 30,  
    2021     2020     2021     2020  
    (dollars in thousands)  
Revenue constant currency growth rate (1)     16 %     19 %     16 %     20 %
Gross profit percentage     77 %     76 %     77 %     76 %
Free cash flow (1)   $ 31,188     $ 21,644     $ 62,793     $ 40,178  
Adjusted EBITDA (1)   $ 46,795     $ 33,604     $ 85,387     $ 59,269  

 

    As of September 30,  
    2021     2020  
Net revenue retention rate (2)     106 %     105 %
Total customers (3)     39,600       39,200  

(1) Revenue constant currency growth rates, free cash flow and Adjusted EBITDA are non-GAAP financial measures. For a reconciliation of revenue constant currency growth rates, free cash flow and to the nearest comparable GAAP measures, see “Reconciliations of Non-GAAP Financial Measures” below.        
(2) We calculate our net revenue retention rate by annualizing constant currency revenue recorded on the last day of the measurement period for only those customers in place throughout the entire measurement period. This revenue includes renewed revenue contracts as well as additional revenue derived from the sale of additional seat licenses as well as additional services sold to these existing customers. We divide the result by revenue on a constant currency basis on the first day of the measurement period for all customers in place at the beginning of the measurement period. The measurement period is the trailing twelve months. The revenue on a constant currency basis is based on the average exchange rates in effect during the respective period.
(3) Reflects the customer count on the last day of the period rounded to the nearest hundred customers. We define a customer as an entity with an active subscription contract as of the measurement date. A customer is typically a parent company or, in a few cases, a significant subsidiary that works with us directly. In determining the number of customers, we do not include customers we acquired from DMARC Analyzer B.V. that transact with us on a credit card basis.
