Business Outlook

Mimecast is providing guidance for the first quarter and fiscal year 2018.

First Quarter 2018 Guidance:

For the first quarter of 2018, constant currency revenue growth is expected to be in the range of 35% to 36% and revenue is expected to be in the range of $54.7 million to $55.3 million. Our guidance is based on exchange rates as of April 30, 2017 and includes an estimated negative impact of $1.0 million resulting from the strengthening of the U.S. dollar compared to the prior year. This resulted from a negative impact related to the British Pound of $2.0 million but was offset by positive impacts from the South African Rand of $1.0 million.  Adjusted EBITDA for the first quarter is expected to be in the range of $3.3 million to $4.3 million. 

Full Year 2018 Guidance:

For the full year 2018, revenue is expected to be the range of $239.4 million to $247.6 million or 28% to 32% revenue growth in constant currency.  Foreign exchange rate fluctuations are positively impacting this guidance by an estimated $0.9 million. Adjusted EBITDA is expected to be in the range of $18.7 million to $20.7 million.

GAAP net loss is the most comparable GAAP measure to Adjusted EBITDA. Adjusted EBITDA differs from GAAP net loss in that it excludes depreciation and amortization, share-based compensation expense, interest income and interest expense, the provision for income taxes and foreign exchange income. 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 loss or a reconciliation of forward-looking Adjusted EBITDA guidance to GAAP net loss.

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 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 operating results. 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 first quarter and full year 2018, expected revenue from entities reporting in foreign currencies will be translated into U.S. dollars using the comparable prior year period's monthly average foreign currency exchange rates.

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 loss, adjusted to exclude: depreciation and amortization, share-based compensation expense, interest income and interest expense, the provision for income taxes and foreign exchange income predominantly related to the elimination of intercompany balances. We define Adjusted EBITDA margin as Adjusted EBITDA over revenue in the period.

Non-GAAP net (loss) income. We define non-GAAP net (loss) income as net loss less share-based compensation expense and the related income tax effects of excluding share-based compensation expense. We consider this non-GAAP financial measure to be a useful metric for management and investors because it excludes the effect of share-based compensation expense 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 (loss) income versus net loss calculated in accordance with GAAP. For example, as noted above, non-GAAP net (loss) income excludes share-based compensation expense and related income tax effects. In addition, the components of the costs that we exclude in our calculation of non-GAAP net (loss) 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 (loss) income and evaluating non-GAAP net (loss) income together with net loss 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, 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 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:

(1) Adjusted EBITDA and revenue constant currency growth rates are non-GAAP measures. For a reconciliation of Adjusted EBITDA and revenue constant currency growth rates to the nearest comparable GAAP measures, see "Reconciliation of Non-GAAP Financial Measures" below.
(2) We calculate our 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. We include add-on, or upsell, revenue from additional employees and services purchased by 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.
