Financial Outlook

As of February 13, 2019, Bandwidth is providing guidance for its first quarter and full year 2019 as follows:

    --  First Quarter 2019 Guidance: CPaaS revenue is expected to be in the
        range of $43.5 million to $44.0 million. Total revenue is expected to be
        in the range of $51.0 million to $51.5 million. Non-GAAP loss per share
        is expected to be in the range of ($0.27) to ($0.30) per share, using
        19.8 million weighted average basic shares outstanding.
    --  Full Year 2019 Guidance: CPaaS revenue is expected to be in the range of
        $201.0 million to $203.0 million. Total revenue is expected to be in the
        range of $231.5 million to $233.5 million. Non-GAAP loss per share is
        expected to be in the range of approximately of ($0.64) to ($0.74) per
        share, using 19.9 million weighted average basic shares outstanding.

Bandwidth has not reconciled its first quarter and full-year guidance related to non-GAAP net loss to GAAP net loss and non-GAAP loss per share to GAAP loss, because stock-based compensation cannot be reasonably calculated or predicted at this time. Accordingly, a reconciliation is not available without unreasonable effort.

Forward-Looking Statements

This press release includes forward-looking statements. All statements contained in this press release other than statements of historical facts, including, without limitation, statements regarding our future financial and business performance for the first quarter 2019 and full-year 2019, attractiveness of our product offerings and platform and the value proposition of our products, are forward-looking statements. The words "anticipate," "believe," "continue," "estimate," "expect," "intend," "guide," "may," "will" and similar expressions and their negatives are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives and financial needs. These forward-looking statements are subject to a number of risks and uncertainties, including, without limitation, risks related to our rapid growth and ability to sustain our revenue growth rate, competition in the markets in which we operate, market growth, our ability to innovate and manage our growth, our ability to expand effectively into new markets, our ability to operate in compliance with applicable laws as well as other risks and uncertainties set forth in the "Risk Factors" section of Form 10-Q for the period ended September 30, 2018, filed with the Securities and Exchange Commission and any subsequent reports that we file with the Securities and Exchange Commission after September 30, 2018. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, we cannot guarantee future results, levels of activity, performance, achievements or events and circumstances reflected in the forward-looking statements will occur. We are under no obligation to update any of these forward-looking statements after the date of this press release to conform these statements to actual results or revised expectations, except as required by law. You should, therefore, not rely on these forward-looking statements as representing our views as of any date subsequent to the date of this press release.

Non-GAAP Financial Measures

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 business metrics, which we believe are helpful to our investors. We use these Non-GAAP financial measures and other business metrics for financial and operational decision-making purposes and as a means to evaluate period-to-period comparisons. We believe that these Non-GAAP financial measures and other business 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.

The presentation of Non-GAAP financial information and other business metrics is not meant to be considered in isolation or as a substitute for the directly comparable financial measures prepared in accordance with GAAP. While our Non-GAAP financial measures and other business metrics are an important tool for financial and operational decision-making and for evaluating our own operating results over different periods of time, we urge investors to review the reconciliation of these financial measures to the comparable GAAP financial measures included above, and not to rely on any single financial measure to evaluate our business.

We define Non-GAAP gross profit as gross profit after adding back depreciation and amortization and stock-based compensation. We add back depreciation and amortization and stock-based compensation because they are non-cash items. We eliminate the impact of these non-cash items, because we do not consider them indicative of our core operating performance. Their exclusion facilitates comparisons of our operating performance on a period-to-period basis. Therefore, we believe that showing gross margin, as adjusted to remove the impact of these non-cash expenses, such as depreciation, amortization and stock-based compensation, is helpful to investors in assessing our gross profit and gross margin performance in a way that is similar to how management assesses our performance. We calculate Non-GAAP gross margin by dividing adjusted gross profit by revenue, expressed as a percentage of revenue.

We define Non-GAAP net income (loss) as net income (loss) adjusted for certain items affecting period to period comparability. Non-GAAP net income (loss) excludes stock-based compensation, change in fair value of shareholders' antidilutive arrangement, amortization of acquired intangible assets related to the Dash acquisition, impairment charges of intangibles assets, loss (gain) on disposal of property and equipment, estimated tax impact of above adjustments, income tax benefit resulting from excess tax benefits associated with the exercise of stock options and vested restricted stock, benefit resulting from the release of the valuation allowance on our deferred tax assets ("DTA"), and impact on remeasurement of DTA as a result of 2017 tax reform.

We define adjusted EBITDA as net income adjusted to reflect the addition or elimination of certain income statement items including, but not limited to: income tax expense (benefit), interest expense, net, depreciation and amortization expense, stock-based compensation expense, impairment of intangible assets, and loss (gain) from disposal of property and equipment. We have presented Adjusted EBITDA because it is a key measure used by our management and board of directors to understand and evaluate our core operating performance, generate future operating plans, and make strategic decisions regarding the allocation of capital. In particular, we believe that the exclusion of certain items in calculating Adjusted EBITDA can produce a useful measure for period-to-period comparisons of our business.

We define Free Cash Flow as net cash provided by or used in operating activities less net cash used in investments of property, plant and equipment activities and capitalized development costs for software for internal use. We believe free cash flow is a useful indicator of liquidity and provides information to management and investors about the amount of cash generated from our core operations that can be used for investing in our business. Free cash flow has certain limitations in that it does not represent the total increase or decrease in the cash balance for the period, it does not take into consideration investment in long-term securities, nor does it represent the residual cash flows available for discretionary expenditures. Therefore, it is important to evaluate free cash flow along with our consolidated statements of cash flows.

We believe that these Non-GAAP financial measures 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 a reconciliation of Non-GAAP guidance measures to corresponding GAAP measures is not available on a forward-looking basis as a result of the uncertainty regarding, and the potential variability of, many of these costs and expenses that we may incur in the future, we have provided a reconciliation of Non-GAAP financial measures and other business metrics to the nearest comparable GAAP measures in the accompanying financial statement tables included in this press release.

We define an active CPaaS customer account at the end of any period as an individual account, as identified by a unique account identifier, for which we have recognized at least $100 of revenue in the last month of the period. We believe that the use of our platform by active CPaaS customer accounts at or above the $100 per month threshold is a stronger indicator of potential future engagement than trial usage of our platform at levels below $100 per month. A single organization may constitute multiple unique active CPaaS customer accounts if it has multiple unique account identifiers, each of which is treated as a separate active CPaaS customer account.

Our dollar-based net retention rate compares the CPaaS revenue from customers in a quarter to the same quarter in the prior year. To calculate the dollar-based net retention rate, we first identify the cohort of customers that generate CPaaS revenue and that were customers in the same quarter of the prior year. The dollar-based net retention rate is obtained by dividing the CPaaS revenue generated from that cohort in a quarter, by the CPaaS revenue generated from that same cohort in the corresponding quarter in the prior year. When we calculate dollar-based net retention rate for periods longer than one quarter, we use the average of the quarterly dollar-based net retention rates for the quarters in such period.
