Raleigh, NC - Bandwidth Inc. (NASDAQ: BAND), a leading global enterprise cloud communications company, today announced financial results for the third quarter ended September 30, 2021.

“Bandwidth continues to play a critical role in the enterprise move to the cloud,” stated David Morken, Chief Executive Officer of Bandwidth. “We delivered another solid quarter, with a number of important customer wins, strong momentum from cross-selling on our global network, and continued growth in our API-driven CPaaS products. The DDoS attacks on our network have sharpened our defenses and made us stronger than ever, and we're in a position to leverage what we've learned to help make the ecosystem safer for enterprise communications.”

“We were pleased to deliver another quarter of strong results, with both top and bottom line results exceeding guidance,” said Daryl Raiford, Chief Financial Officer of Bandwidth. “Our CPaaS non-GAAP gross margins continue to expand, achieving a record 54% and enhanced by the inclusion of the higher margin international business. Despite the challenges caused by the DDoS attacks our fundamental growth drivers remain unchanged. We remain well positioned to serve a large and growing global communications market that is benefiting from transformational secular trends.

Third Quarter Customer and Company Highlights
One of Bandwidth's largest and longest-tenured customers signed a contract for global service in the third quarter. This deal was possible only with the global reach we achieved with the Voxbone acquisition. Fourth quarter 2021 testing of voice and messaging in select countries is expected to ramp throughout 2022.
A global leader in electronic signature chose Bandwidth to move its multi-country contact center stack to the cloud. The customer values Bandwidth’s global reach and ability to integrate with nearly every major communications platform an enterprise needs, from UCaaS to CCaaS.
Bandwidth signed a new deal in the third quarter with a $16 billion, Fortune 200 managed care provider. This provider chose Bandwidth because we are uniquely able to power their entire communications stack in the cloud -- both UCaaS and CCaaS. Bandwidth APIs enable the provider to manage its own communications system without specialized telecom expertise.

Financial Outlook
Bandwidth’s outlook assumes current business conditions, current foreign currency exchange rates and includes the estimated impact of the previously disclosed DDoS attacks. Bandwidth is providing guidance for its fourth quarter and full year 2021 as follows:
Q4 2021 Guidance
Full Year 2021 Guidance
CPaaS Revenue ($ millions)94.5 - 99.5407.0 - 412.0
Total Revenue ($ millions)115.7 - 120.7480.5 - 485.5
Non-GAAP earnings per share ($)(0.15) - (0.11)0.74 - 0.78
Weighted Average Diluted Shares Outstanding (millions)25.126.5

Bandwidth has not reconciled its fourth quarter and full-year guidance related to non-GAAP net earnings or loss to GAAP net earnings or loss and non-GAAP earnings or loss per share to GAAP earnings or 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, future financial and business performance for the fourth quarter 2021 and full-year 2021, attractiveness of our product offerings, our platform, the value proposition of our products, and our assessment of the impact of the distributed denial of service ("DDoS") attacks discussed herein and in previous press releases 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, legal, reputational and financial risks which may result from the DDoS attacks or other cybersecurity incidents, risks that the anticipated benefits of the acquisition of Voxbone may not be fully realized or may take longer to realize than expected, 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 and any subsequent reports that we file with the Securities and Exchange Commission. 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
3


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, 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, such as depreciation, amortization of acquired intangible assets related to acquisitions 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 (loss) income as net (loss) income adjusted for certain items affecting period to period comparability. Non-GAAP net (loss) income excludes stock-based compensation, amortization of acquired intangible assets, amortization of debt discount and issuance costs for convertible debt, acquisition related expenses, impairment charges of intangibles assets, loss (gain) on disposal of property and equipment, estimated tax impact of above adjustments, income tax (benefit) provision resulting from excess tax benefits associated with the exercise of stock options, vesting of restricted stock units and equity compensation, and expense resulting from recording the valuation allowance on our deferred tax assets (“DTA”).
We define adjusted EBITDA as net (loss) income 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, 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 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 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.
4


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.
