Third Quarter Customer and Operational Highlights
Introduced the next-generation Universal Platform bringing the power of Bandwidth in one consistent global experience for all real-time communications needs, with new features, upgraded capabilities, and a modernized global network underpinning the platform to make it easier to consolidate and expand into new markets around the world.
Bandwidth announced it now offers the largest ecosystem of bring-your-own-carrier (BYOC) integrations of any provider in the world within the Maestro communications platform – giving enterprises more ways to solve complex communications challenges.
Bandwidth has registered as an RBM (RCS Business Messaging) partner with Google, setting itself up to enable RCS (Rich Communication Services) across all key markets.
Bandwidth announced Number Reputation Management is coming soon as a solution to correct false “spam” labels and make sure enterprise’s urgent and important calls are displayed correctly so they can be answered.
A high-volume patient engagement platform switched to Bandwidth for text messaging. They needed message deliverability assurance and message performance insights to ensure timely patient communications.
A large, diversified credit union chose Bandwidth to provide voice services for its new, modernized on-premise contact center. Bandwidth’s all-IP network and Maestro platform made it easy for the customer to integrate with a modern tech stack and enables them to add new services in the future.

Financial Outlook
Bandwidth’s outlook is based on current indications for its business, which are subject to change. Bandwidth is providing guidance for its fourth quarter and full year 2024 as follows (in millions):
4Q 2024 Guidance
Full Year 2024 Guidance
Revenue
$198 - $208
$737 - $747
Adjusted EBITDA
$19 - $21
$78 - $80
Bandwidth has not reconciled its fourth quarter and full year 2024 guidance related to Adjusted EBITDA to GAAP net income or loss, because stock-based compensation cannot be reasonably calculated or predicted at this time. Accordingly, a reconciliation is not available without unreasonable effort.

Upcoming Investor Conference Schedule
Barclays Global Technology Conference in San Francisco, CA. Meetings with John Bell, Chief Product Officer and Shiv Hira, EVP Finance on Wednesday, December 11th, 2024.

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, future financial and business performance for the quarter and year ending December 31, 2024, the success of our product offerings and our platform, and the value proposition of our products, are forward-looking statements. The words “anticipate,” “assume,” “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, macroeconomic conditions both in the U.S. and globally, legal, reputational and financial risks which may result from ever-evolving cybersecurity threats, our ability to operate in compliance with applicable laws, as well as other risks and uncertainties set forth in the “Risk Factors” section of our latest Form 10-K filed with the Securities and Exchange Commission (the “SEC”) and any subsequent reports that we file with the SEC. 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 condensed 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 below, 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, amortization of acquired intangible assets related to acquisitions and stock-based compensation. We add back depreciation, amortization of acquired intangible assets related to acquisitions 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, is helpful to investors in assessing our gross profit and gross margin
3


performance in a way that is similar to how management assesses our performance. We calculate Non-GAAP gross margin by dividing Non-GAAP gross profit by cloud communications revenue, which is revenue less pass-through messaging surcharges.
We define Non-GAAP net income (loss) as net income or loss adjusted for certain items affecting period to period comparability. Non-GAAP net income (loss) excludes stock-based compensation, amortization of acquired intangible assets related to acquisitions, amortization of debt discount and issuance costs for convertible debt, acquisition related expenses, impairment charges of intangibles assets, net cost associated with early lease terminations and leases without economic benefit, (gain) loss on sale of business, net (gain) loss on extinguishment of debt, gain on business interruption insurance recoveries, non-recurring items not indicative of ongoing operations and other, and estimated tax impact of above adjustments, net of valuation allowances.
We define Adjusted EBITDA as net income or losses from continuing operations, adjusted to reflect the addition or elimination of certain statement of operations items including, but not limited to: income tax (benefit) provision, interest (income) expense, net, depreciation and amortization expense, acquisition related expenses, stock-based compensation expense, impairment of intangible assets, (gain) loss on sale of business, net cost associated with early lease terminations and leases without economic benefit, net (gain) loss on extinguishment of debt, gain on business interruption insurance recoveries, and non-recurring items not indicative of ongoing operations and other. 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 and trends, 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 the acquisition of property, plant and equipment 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 condensed 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.

(2) The estimated tax-effect of adjustments is determined by recalculating the tax provision on a Non-GAAP basis. The Non-GAAP effective income tax rate was 15.5% and 11.0% for the nine months ended September 30, 2024 and 2023, respectively. For the nine months ended September 30, 2024, the Non-GAAP effective income tax rate differed from the federal statutory tax rate of 21% in the U.S. primarily due to the research and development tax credits generated in 2024. We analyze the Non-GAAP valuation allowance position on a quarterly basis. In the fourth quarter of 2022, we removed the valuation allowance against all U.S. deferred tax assets for Non-GAAP purposes as a result of cumulative Non-GAAP U.S. income over the past three years and a significant depletion of net operating loss and tax credit carryforwards on a Non-GAAP basis. As of September 30, 2024, we have no valuation allowance against our remaining deferred tax assets for Non-GAAP purposes.
(3) Non-GAAP net income is increased for interest expense as part of the calculation for diluted Non-GAAP earnings per share.
