Fourth Quarter Business Highlights:

• We announced the addition of Impersonation Protect to Mimecast Targeted Threat Protection product line. Impersonation Protect is the first service available to tackle the growing threat from business email compromise attacks, also called CEO Fraud or whaling. This attack, which bypasses traditional security gateways as there is no malware to detect, uses social engineering to target individual employees within specific departments responsible for the data or finances that criminals are targeting.

• 14% of customers are using Mimecast in conjunction with Microsoft® Office 365™ compared to 12% in the third quarter.  Office 365™ continues to be a catalyst for growth for the Company as more than 600 new customers in the fourth quarter improved their security protection, data archiving and service continuity by combining these two cloud-only services.
• We extended our leadership team with the addition of two experienced executives: Alex Bender, Senior Vice President of Global Marketing and Mark Basler, Senior Vice President of Product Management.
• We passed an independent Health Insurance Portability and Accountability Act (HIPAA) Security Compliance Assessment and Service Organization Control 2 Type 1 (SOC 2 Type 1) Independent Service Audit allowing Mimecast to better serve covered entities.

Business Outlook

Mimecast is providing guidance for the first quarter and full year 2017

First Quarter 2017 Guidance:

For the first quarter of 2017, we expect constant currency revenue growth to be between 24% and 26% and revenue to be between $39.5 million to $39.9 million.  Exchange rates in certain currencies we operate in have weakened in the period due to the strengthening of the US dollar compared to the same period in the prior year.  Fluctuations in these rates have impacted our revenue guidance by $1.8 million. Approximately $1.0 million of this impact relates to the translation of South African Rand based revenue and the remainder relates to British Pound based revenue. We believe that constant currency revenue growth is a useful way to measure the underlying strength of our business as it excludes these short term fluctuations.  Adjusted EBITDA is expected to be in the range of $0.3 million to $1.4 million.

Full Year 2017 Guidance:

For the full year 2017, we expect constant currency revenue growth to be between 22% and 26% and revenue to be between $170.2 million to $175.9 million.  Foreign exchange rate fluctuations are impacting this guidance by $3.2 million of which $1.0 million relates to the South African Rand and $2.2 million relates to the British Pound.

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 first quarter and full year 2017, expected revenue from entities reporting in foreign currencies was 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) income, adjusted to exclude: depreciation and amortization, share-based compensation expense, restructuring expense, interest income and interest expense, the provision for income taxes and foreign currency exchange (expense) 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) income less 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 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) income calculated in accordance with GAAP. For example, as noted above, non-GAAP net (loss) income excludes share-based compensation expense. 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) income 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 "Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources" section of our reports filed with the SEC.

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 up 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.
