Investor Presentation May 2026

![](a2026bandwidthinvestorpr002.jpg)

Legal disclaimer This presentation includes forward-looking statements. All statements contained in this presentation other than statements of historical facts, including, without limitation, the success of our product offerings and our platform, and the value proposition of our products, and anticipated growth of the addressable market, 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 presentation 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 presentation. This presentation also includes certain guidance on non-GAAP financial measures. These non-GAAP financial measures are in addition to, and not as a substitute for or superior to measures of financial performance prepared in accordance with GAAP. There are a number of limitations related to the use of these non-GAAP financial measures versus their nearest GAAP equivalents. For example, other companies may calculate non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of the Company's non-GAAP financial measures as tools for comparison. The Company provides a reconciliation of certain non-GAAP measures to the most directly comparable GAAP measures, which are available in the earnings press release for the relevant period and in the appendix of this presentation. Market data and industry information used throughout this Presentation are based on management's knowledge of the industry and the good faith estimates of management. Management also relied, to the extent available, upon management's review of independent industry surveys and publications and other publicly available information prepared by a number of third party sources. The market data and industry information used in this presentation involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. Although we believe that these sources are reliable, we cannot guarantee the accuracy or completeness of this information, and we have not independently verified this information. While we believe the estimated market position, market opportunity and market size information included in this presentation are generally reliable, such information, which is derived in part from management's estimates and beliefs, is inherently uncertain and imprecise. No representations or warranties are made by the Company or any of its affiliates as to the accuracy of any such statements or projections. Projections, assumptions and estimates of our future performance and the future performance of the industry in which we operate are necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including those described above. These and other factors could cause results to differ materially from those expressed in our estimates and beliefs and in the estimates prepared by independent parties.

Definitions Adjusted EBITDA: 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. Adjusted EBITDA margin: Adjusted EBITDA margin is calculated by dividing adjusted EBITDA by cloud communications revenue, which excludes pass-through messaging surcharge revenue. Average annual customer revenue: Average annual customer revenue is the trailing twelve month revenue divided by the average [number] of active customers from the current quarter and number of active customers from the same quarter of the prior year. Cloud communications revenue: Total revenue less pass-through messaging surcharge revenue. Customer name retention rate: Customer name retention rate (CNRR) is defined as the percentage of customers with $100k or greater revenue in the prior twelve month period that remain customers in the current twelve month period. Free cash flow: Free cash flow represents 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 of software for internal use. Free cash flow margin: Free cash flow margin is calculated by dividing free cash flow by cloud communications revenue, which excludes pass-through messaging surcharge revenue. Messaging surcharge revenue: Revenue derived from fees imposed by certain carriers within the messaging ecosystem, which are subsequently invoiced and passed through to customers. Net Retention Rate ("NRR"): To calculate the net retention rate, we first identify the cohort of customers that generated revenue in the same quarter of the prior year. The net retention rate is obtained by dividing the revenue generated from that cohort in a quarter, by the revenue generated from that same cohort in the corresponding quarter in the prior year. The net retention rate reported in a quarter is then obtained by averaging the result from that quarter by the corresponding results from each of the prior three quarters. Customers of acquired businesses are included in the subsequent year's calendar quarter of acquisition. Non-GAAP Gross Profit: Gross profit after adding back the following items: depreciation and amortization; amortization of acquired intangible assets related to acquisitions; and stock-based compensation. Non-GAAP Gross Margin: Non-GAAP Gross Margin is calculated by dividing non-GAAP gross profit by cloud communications revenue, which excludes pass-through messaging surcharge revenue. 26
