First Quarter and Full-Year 2020 Guidance

Rapid7 anticipates annualized recurring revenue, revenue, non-GAAP (loss) income from operations, and non-GAAP net (loss) income per share to be in the following ranges:

First Quarter and Full-Year 2020 Guidance (in millions, except per share data)
           
  First Quarter 2020   Full-Year 2020
Annualized recurring revenue         $ 420.0     $ 426.8  
Year-over-year growth         24 %   26 %
Revenue $ 91.6   to $ 93.2     $ 396.0   to $ 404.0  
Year-over-year growth 25 % to 27 %   21 % to 24 %
Non-GAAP (loss) income from operations $ (6.3 ) to $ (5.3 )   $ 7.0   to $ 11.0  
Non-GAAP net (loss) income per share $ (0.13 ) to $ (0.11 )   $ 0.11   to $ 0.18  
Weighted average shares outstanding     50.2           55.0  

Guidance for the first quarter and full-year 2020 does not include any potential impact of foreign exchange gains or losses. The weighted average shares outstanding for the first quarter of 2020 represent basic shares outstanding given our projected non-GAAP net loss. The weighted average shares outstanding for full year 2020 represent non-GAAP diluted shares outstanding given our projected non-GAAP net income.

Non-GAAP guidance excludes estimates for stock-based compensation expense, amortization of acquired intangible assets, amortization of debt discount and issuance costs, and certain non-recurring items. Rapid7 has provided a reconciliation of  each non-GAAP guidance measure to the most comparable GAAP measures in the financial statement tables included in this press release. The reconciliation does not reflect any items that are unknown at this time, such as acquisition-related expenses, follow-on public offering costs, and litigation-related expenses which we are not able to predict without unreasonable effort due to their inherent uncertainty.

Rapid7 will host a conference call today, February 10, 2020, to discuss its results at 4:30 p.m. Eastern Time. The call will be accessible by telephone at 877-357-4230 (domestic) or 629-228-0721 (international).

Non-GAAP Financial Measures and Other Business Metrics

To supplement our consolidated financial statements, which are prepared and presented in accordance with generally accepted accounting principles in the United States, or GAAP, we provide investors with certain non-GAAP financial measures and other metrics, which we believe are helpful to our investors. We use these non-GAAP financial measures and other metrics for financial and operational decision-making purposes and as a means to evaluate period-to-period comparisons. We also use certain non-GAAP financial measures as performance measures under our executive bonus plan. We believe that these non-GAAP financial measures and other metrics provide useful information about our operating results, enhance the overall understanding of past financial performance and future prospects and allow for greater transparency with respect to metrics used by our management in its financial and operational decision-making.

While our non-GAAP financial measures are an important tool for financial and operational decision-making and for evaluating our own operating results over different periods of time, you should review the reconciliation of our non-GAAP financial measures to the comparable GAAP financial measures included below, and not rely on any single financial measure to evaluate our business.

Non-GAAP Financial Measures
We disclose the following non-GAAP financial measures: non-GAAP gross profit, non-GAAP income (loss) from operations, non-GAAP net income (loss), non-GAAP net income (loss) per share and adjusted EBITDA.

We define non-GAAP gross profit, non-GAAP income (loss) from operations, non-GAAP net income (loss) and non-GAAP net income (loss) per share as the respective GAAP balances excluding the effect of stock-based compensation expense, amortization of acquired intangible assets, amortization of debt discount and issuance costs and certain other items such as acquisition-related expenses, follow-on public offering costs, and litigation-related expenses. Non-GAAP net income (loss) per basic and dilutive share is calculated as non-GAAP net income (loss) divided by the weighted average shares used to compute net income (loss) per share, with the number of weighted average shares decreased to reflect the anti-dilutive impact of the capped call transactions entered into in connection with the 1.25% convertible senior note issued in August 2018.

We believe these non-GAAP financial measures are useful to investors in assessing our operating performance due to the following factors:

Stock-based compensation expense. We exclude stock-based compensation expense because of varying available valuation methodologies, subjective assumptions and the variety of equity instruments that can impact our non-cash expense. We believe that providing non-GAAP financial measures that exclude stock-based compensation expense allows for more meaningful comparisons between our operating results from period to period.

Amortization of acquired intangible assets. We believe that excluding the impact of amortization of acquired intangible assets allows for more meaningful comparisons between operating results from period to period as the intangible assets are valued at the time of acquisition and are amortized over several years after the acquisition.

Amortization of debt discount and issuance costs. In August 2018, we issued $230 million of convertible senior notes, which bear interest at an annual fixed rate of 1.25%. The imputed interest rate of the convertible senior notes was approximately 7.37%. This is a result of the debt discount recorded for the conversion feature that is required to be separately accounted for as equity, and debt issuance costs, which reduce the carrying value of the convertible debt instrument. The debt discount is amortized as interest expense together with the issuance costs of the debt. The expense for the amortization of debt discount and debt issuance costs is a non-cash item, and we believe the exclusion of this interest expense provides a more useful comparison of our operational performance in different periods.

Litigation-related expenses. We exclude certain litigation-related expenses consisting of professional fees and related costs incurred by us related to significant litigation outside the ordinary course of business. We believe it is useful to exclude such expenses because we do not consider such amounts to be part of our ongoing operations.

Acquisition-related expenses and follow-on public offering costs. We exclude acquisition-related expenses and follow-on public offering costs as costs that are unrelated to the current operations and neither are comparable to the prior period nor predictive of future results.

Anti-dilutive impact of capped call transaction. In connection with the issuance of our convertible senior notes, we entered into capped call transactions to offset potential dilution from the embedded conversion feature in the notes. Although we cannot reflect the anti-dilutive impact of the capped call transactions under GAAP, we do reflect the anti-dilutive impact of the capped call transactions in non-GAAP net income (loss) per basic and diluted share to provide investors with useful information in evaluating the financial performance of the company on a per share basis.

Adjusted EBITDA (non-GAAP). Adjusted EBITDA is a non-GAAP measure that we define as net loss before (1) interest income, (2) interest expense, (3) other income (expense), net, (4) provision for income taxes, (5) depreciation expense, (6) amortization of intangible assets, (7) stock-based compensation expense, and (8) certain other items.  We believe that the use of adjusted EBITDA is useful to investors and other users of our financial statements in evaluating our operating performance because it provides them with an additional tool to compare business performance across companies and across periods. Adjusted EBITDA should not be considered as a substitute for other measures of financial performance reported in accordance with GAAP. There are limitations to using this non-GAAP financial measure, including that other companies may calculate this measure differently than we do, that it does not reflect our capital expenditures or future requirements for capital expenditures and that it does not reflect changes in, or cash requirements for, our working capital and excludes some items that are cash based.

Other Metrics
Annualized Recurring Revenue (ARR). ARR is defined as the annual value of all recurring revenue related contracts in place at the end of the period. ARR should be viewed independently of revenue and deferred revenue as ARR is an operating metric and is not intended to be combined with or replace these items. ARR is not a forecast of future revenue and can be impacted by contract start and end dates and renewal rates, and does not include revenue reported as perpetual license or professional services revenue in our consolidated statement of operations.

Number of Customers. We define a customer as any entity that has (1) an active Rapid7 contract or a contract that expired within 90 days or less of the applicable measurement date; and for Logentries products, those customers with a contract value equal to or greater than $2,400 per year, or (2) purchased Rapid7 professional services within the 12 months preceding the applicable measurement date.

ARR per Customer. We define ARR per customer as ARR divided by the number of customers at the end of the period.

Recurring Revenue. We define recurring revenue as revenue from term software licenses, content subscriptions, managed services, cloud-based subscriptions and maintenance and support.

Renewal Rate. We calculate our renewal rate by dividing the dollar value of renewed customer agreements, including upsells and cross-sells of additional products, but excluding professional services, in a trailing 12-month period by the dollar value of the corresponding customer agreements.
