1. Organization and Description of Business
Bandwidth Inc. (together with its subsidiaries, “Bandwidth” or the “Company”) was founded in July 2000 and incorporated in Delaware on March 29, 2001. The Company’s headquarters are located in Raleigh, North Carolina. The Company is an international cloud-based, software-powered communications platform-as-a-service (“CPaaS”) provider that enables enterprises to create, scale and operate voice or messaging communications services across any mobile application or connected device.

2. Summary of Significant Accounting Policies
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K, filed with the SEC on February 23, 2023.
The condensed consolidated balance sheet as of December 31, 2022, included herein, was derived from the audited financial statements as of that date, but does not include all disclosures, including certain notes required by GAAP on an annual reporting basis.
In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2023 or any future period.
Principles of Consolidation
The condensed consolidated financial statements include the accounts of Bandwidth Inc. and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates
The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and judgments that affect the amounts reported in these financial statements and accompanying notes. These estimates in the condensed consolidated financial statements include, but are not limited to, allowance for doubtful accounts, reserve for expected credit losses, reserve for sales credits, recoverability of long lived and intangible assets, fair value of acquired intangible assets and goodwill, discount rates used in the valuation of right-of-use assets and lease liabilities, the fair value of the liability of the Company’s Convertible Notes (as defined herein), estimated period of benefit, valuation allowances on deferred tax assets, certain accrued expenses and contingencies, economic and demographic actuarial assumptions related to pension and other postretirement benefit costs and liabilities. Although the Company believes that the estimates it uses are
12

Table of Contents
Notes to Condensed Consolidated Financial Statements (continued)






reasonable, due to the inherent uncertainty involved in making these estimates, actual results reported in future periods could differ from those estimates.
Marketable Securities
The Company classifies marketable securities as available-for-sale at the time of purchase and reevaluates such classification as of each balance sheet date. The Company may sell these securities at any time for use in current operations even if they have not yet reached maturity. As a result, the Company classifies investments with maturities greater than 90 days as marketable securities in the accompanying condensed consolidated balance sheets. The Company evaluates its investments to assess whether the amortized cost basis is in excess of estimated fair value and determines what amount of that difference, if any, is caused by expected credit losses. Allowances for credit losses are recognized as a charge in other income (expense), net on the condensed consolidated statements of operations, and any remaining unrealized losses are included in accumulated other comprehensive loss on the condensed consolidated balance sheets. Due to the nature and investment grade of the Company’s marketable securities, there were no credit losses recorded for the three and nine months ended September 30, 2023. There have been no impairment charges for any unrealized losses during the period.
Accounts Receivable and Current Expected Credit Losses
Accounts receivable are stated at realizable value, net of allowances, which includes an allowance for doubtful accounts and a reserve for expected credit losses. The allowance for doubtful accounts is based on management’s assessment of the collectability of its customer accounts. The Company regularly reviews the composition of the accounts receivable aging, historical bad debts, changes in payment patterns, customer creditworthiness, current economic trends, and reasonable and supportable forecasts about the future. Relevant risk characteristics include customer size and historical loss patterns. Management has evaluated the expected credit losses related to trade accounts receivable and determined that an allowance of approximately $1.3 million and $1.2 million for uncollectible accounts and customer balances that are disputed was required as of September 30, 2023 and December 31, 2022, respectively. Refer to Note 4, “Financial Statement Components” to these condensed consolidated financial statements, for a rollforward of the components of the allowances for the three and nine months ended September 30, 2023 and 2022.
The Company includes unbilled receivables in its accounts receivable balance. Generally, these receivables represent earned revenue from services provided to customers, which will be billed in the next billing cycle. All amounts are considered collectible and billable. As of September 30, 2023 and December 31, 2022, unbilled receivables were $39.7 million and $33.9 million, respectively.
Concentration of Credit Risk
Financial instruments that are exposed to concentration of credit risk consist primarily of cash and cash equivalents, marketable securities and trade accounts receivable. The Company maintains its cash, cash equivalents and marketable securities with high credit-quality financial institutions. Certain balances held by such financial institutions exceed insured limits.
With regard to customers, credit evaluation and account monitoring procedures are used to minimize the risk of loss. The Company believes that no additional credit risk beyond amounts provided for by the allowance for doubtful accounts are inherent in accounts receivable. As of September 30, 2023 and December 31, 2022, no individual customer represented more than 10% of the Company’s accounts receivable, net of allowance for doubtful accounts.
For the three and nine months ended September 30, 2023 and 2022, no individual customer represented more than 10% of the Company’s revenue.

Business Interruption Insurance Recovery
Beginning in September 2021, the Company’s communications network was subjected to a distributed denial of service attack (the “DDoS Attack”) that caused intermittent communications services disruptions affecting certain of its markets and customers. During the period of the DDoS Attack, the Company maintained certain insurance coverage, including business interruption insurance, intended to cover such circumstances. In June 2023, the Company resolved its claim with an insurer, pursuant to which the Company was entitled to receive $4.0 million in proceeds from business interruption insurance, which was recorded within gain on business interruption insurance recoveries on the Company’s condensed consolidated statements of operations in the nine months ended September 30, 2023. The proceeds were received in full in July 2023.
Recent Accounting Pronouncements Not Yet Adopted
There were no recent accounting pronouncements not yet adopted during the three and nine months ended September 30, 2023 that were significant to the Company.

3. Fair Value Measurements
The Company uses a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. The hierarchy requires use of observable inputs when available, and to minimize the use of unobservable inputs when determining fair value. The three tiers are defined as follows:
Level 1. Observable inputs based on unadjusted quoted prices in active markets for identical assets or liabilities;
Level 2. Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and
Level 3. Unobservable inputs for which there is little or no market data, which requires the Company to develop its own assumptions.
A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value as of September 30, 2023 and December 31, 2022 because of the relatively short duration of these instruments. Marketable securities consist of time deposits, corporate debt securities, U.S. treasury securities, and commercial paper not otherwise classified as cash equivalents. All marketable securities are considered to be available-for-sale and are recorded at their estimated fair values. Unrealized gains and losses for available-for-sale securities are recorded in accumulated other comprehensive loss.
The Company evaluated its financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level in which to classify them for each reporting period. The following tables
