Notes to Condensed Consolidated Financial Statements

(In Thousands Except Share and per Share Amounts)

(Unaudited)

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 a cloud-based, software-powered communications platform-as-a-service (“CPaaS”) provider that enables enterprises to create, scale and operate voice or text communications services across any mobile application or connected device or enterprises.

The Company has two operating and reportable segments, CPaaS and Other. CPaaS revenue is derived from usage and monthly services fees charged for usage of Voice, Messaging, 911 and Phone Numbers solutions through the Company’s proprietary CPaaS software application programming interfaces. Other revenue consists of fees charged for services provided such as: SIP trunking, data resale, and a hosted Voice-over Internet Protocol (“VoIP”). The Other segment also includes revenue from traffic generated by other carriers (“CABS”), SMS registrations fees and other miscellaneous product lines.

Initial Public Offering

On November 9, 2017, the Company's Registration Statement on Form S-1 relating to the initial public offering (“IPO”) of its Class A common stock was declared effective by the SEC. Immediately prior to the closing of the initial public offering, the Company’s certificate of incorporation was amended such that (i) each share of the Company’s then-outstanding Class A voting common stock (“Old Class A common stock”) was reclassified as one share of Class B common stock (“New Class B common stock”), which has ten votes per share, (ii) each share of the Company’s then-outstanding Class B non-voting common stock (“Old Class B common stock”) was reclassified as one share of Class A common stock ("New Class A common stock"), which has one vote per share and (iii) options and warrants exercisable into the Company’s Old Class A common stock and Old Class B common stock became exercisable into New Class B common stock and New Class A common stock, respectively. In addition, immediately prior to pricing of the IPO, all shares of the Company’s then-outstanding convertible preferred stock were converted into New Class B common stock. In connection with the Company’s IPO 4,000,000 shares of the Company's New Class A common stock were sold at an initial public offering price of $20.00 per share for proceeds of approximately $74,400, net of underwriting discounts and commissions.

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

Table of Contents

applicable rules and regulations of the SEC regarding interim financial reporting. Certain information and note 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 condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the final prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act on November 13, 2017 (the “Prospectus”).

The Company had no components of other comprehensive income during any of the periods presented, and as such, a separate consolidated statement of comprehensive income is not presented.

The condensed consolidated balance sheet as of December 31, 2016, 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 income and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2017 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 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. Although the Company believes the estimates it uses are reasonable, due to the inherent uncertainty involved in making these estimates, actual results reported in future periods could differ from those estimates. These estimates in the condensed consolidated financial statements include, but are not limited to, allowance for doubtful accounts, recoverability of long-lived and intangible assets, customer relationship period, valuation allowances on tax assets, certain accrued expenses, and contingencies.

Concentration of Credit Risk

Financial instruments that are exposed to concentration of credit risk consist primarily of cash and cash equivalents and trade accounts receivable. Cash deposits may be in excess of insured limits. The Company believes that the financial institutions that hold its cash deposits are financially sound and, accordingly, minimal credit risk exists with respect to these balances.

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. No individual customer represented more than 10 percent of accounts receivable as of December 31, 2016 and September 30, 2017.

For the three and nine months ended September 30, 2016 and 2017, no individual customer represented more than 10 percent of the Company’s total revenue.

Significant Accounting Policies

There have been no changes to our significant accounting policies described in the Prospectus.

Recent Accounting Pronouncements Not Yet Adopted

In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-09, Compensation-Stock Compensation (Topic 718), Scope of Modification Accounting, which amends the scope of modification accounting for share-based payment arrangements. The ASU provides guidance on the types of changes to terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718, Compensation-Stock Compensation. ASU 2017-09 is effective for fiscal years and interim periods within those years beginning after December 15, 2017, and early adoption is permitted. The Company is evaluating the impact of this guidance on its consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which simplifies the accounting for goodwill impairment. The ASU requires impairment charges to be based on the first step in today’s two-step impairment test under Accounting Standards Codification (“ASC”) 350. ASU 2017-04 is effective for annual and interim impairment tests performed in periods beginning after December 15, 2021, and early adoption is permitted. The Company is evaluating the impact of this guidance on its consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805) Clarifying the Definition of a Business, which amends the guidance of FASB Accounting Standards Codification Topic 805, “Business Combinations”, adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. This guidance is effective for annual and interim periods beginning after December 15, 2017, and early adoption is permitted under certain circumstances. The adoption of this standard is dependent upon future transactions.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments, which clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. The guidance also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. ASU 2016-15 is effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019, and early adoption is permitted. Entities will have to apply the guidance retrospectively, but if it is impracticable to do so for an issue, the amendments related to that issue would be applied prospectively. The Company is evaluating the impact of this guidance on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases. The standard will affect all entities that lease assets and will require lessees to recognize a lease liability and a right-of-use asset for all leases (except for short- term leases that have a duration of less than one year) as of the date on which the lessor makes the underlying asset available to the lessee. For lessors, accounting for leases is substantially the same as in prior periods. ASU 2016-02 is effective for fiscal years beginning after December 15, 2019, and interim periods within annual periods beginning after December 15, 2020, and early adoption is permitted. For leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, lessees and lessors must apply a modified retrospective transition approach. While the Company expects the adoption of this standard to result in an increase to the reported assets and liabilities, it has not yet determined the full impact that the adoption of this standard will have on its financial statements and related disclosures.

Table of Contents

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. This new guidance will replace most existing. GAAP guidance on this topic. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the effective date, which deferred by one year the effective date for the new revenue reporting standard for entities reporting under GAAP. In accordance with the deferral, this guidance will be effective beginning January 1, 2019. This guidance can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. Early adoption is permitted beginning January 1, 2017. In December 2016, the FASB issued ASU 2016-20, Revenue from Contracts with Customers, Technical Corrections and Improvements to Topic 606, which made twelve additional technical corrections and improvements to the new revenue standard. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) clarifying the implementation guidance on principal versus agent considerations. Specifically, an entity is required to determine whether the nature of a promise is to provide the specified good or service itself (that is, the entity is a principal) or to arrange for the good or service to be provided to the customer by the other party (that is, the entity is an agent). The determination influences the timing and amount of revenue recognition. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers, Identifying Performance Obligations and Licensing, clarifying the implementation guidance on identifying performance obligations and licensing. Specifically, the amendments reduce the cost and complexity of identifying promised goods or services and improve the guidance for determining whether promises are separately identifiable. The amendments also provide implementation guidance on accounting for an entity’s promise to grant a license. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers, Narrow-Scope Improvements and Practical Expedients, clarifying guidance on assessing collectability, presentation of sales taxes, noncash consideration, completed contracts and contract modifications. The effective date and transition requirements for ASU 2016-20, ASU 2016-08 and ASU 2016-10 are the same as the effective date and transition requirements for ASU 2014-09.

The Company is still assessing all potential impacts of the new standard on its consolidated financial statements. Given the comprehensive nature of the standard, the Company has already taken steps to begin assessing the impact on its consolidated financial results. It has completed a preliminary diagnostic, in order to highlight potential differences between current accounting policies and the new standard, and has begun drafting memos to document its accounting positions. Additionally, the Company engaged a third-party service provider to assist in its evaluation of customer contracts and to identify the attributes that could result in a different accounting treatment under ASU 2014-09. From an information technology perspective, the Company has identified a new technology solution which meets its business requirements and will be implemented to comply with ASC 2014-09. The Company has not reached a conclusion as to whether the quantitative effect of the adoption of the new standard on its revenue streams will be material. It will continue to monitor and assess the impact of the changes of the new standard and the related interpretations of its application as they become available.

3. Discontinued Operations

On April 20, 2015, the Company created a wholly owned subsidiary, Republic Wireless, Inc. (“Republic”), which was incorporated in Delaware. On November 30, 2016, the Company completed a pro-rata distribution of the common stock of Republic to its stockholders of record as of the close of business (the “Spin-Off”). Each of its stockholders received one share of Republic common stock for each share of Bandwidth common or redeemable convertible preferred stock held as of the close of business on November 30, 2016.

4. Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value as of December 31, 2016 and September 30, 2017 because of the relatively short duration of these instruments. The carrying value of long-term debt approximates fair value given the interest rates are based on market rates.

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 table summarizes the assets and liabilities measured at fair value as of December 31, 2016 and September 30, 2017:

There were no transfers between Levels 1, 2 or 3 during the year ended December 31, 2016 or the nine months ended September 30, 2017.

The money market account is included in cash and cash equivalents in the consolidated balance sheets as of December 31, 2016 and September 30, 2017.

On February 22, 2011, the Company entered into an agreement with the Principal Non-Founder Stockholders ("Principal Stockholders"). Under the terms of the agreement, the Principal Stockholders received the right (“shareholders' anti-dilutive arrangement”) to purchase a pro-rata number of shares based on their ownership percentage of outstanding shares, when certain option holders exercise his or her stock option. The price at which the Principal Stockholders may purchase their pro-rata shares matches the exercise price of the option exercised. The Principal Stockholders have 90 days from the date of receipt of notice to inform the Company of their intention to purchase stock under the terms of the agreement. On a quarterly basis, the Company adjusts this liability to fair value.

The agreement terminates by one of the following events:


•	closing of a “Qualified Public Offering,” which is defined as one resulting in aggregate net proceeds to the Company equal to or greater than $20 million, or


•	a “true sale” as defined in the Investors’ Rights Agreement.

Upon termination of the agreement, this liability would terminate.

The shareholders’ anti-dilutive arrangement is included in other liabilities in the consolidated balance sheets as of December 31, 2016 and September 30, 2017. The change in fair value of the Level 3 liability resulted in $136 and $689 of additional expense for the three and nine months ended September 30, 2017, respectively, which is recorded in other expense in the condensed consolidated statements of operations and comprehensive income.

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(In Thousands Except Share and per Share Amounts)

The fair value of the shareholders’ anti-dilutive arrangement is estimated using the Black-Scholes-Merton option pricing model. The significant unobservable inputs used in the fair value measurement of the shareholders’ anti-dilutive arrangement are the fair value of the Company’s stock and the expected term of the options. The expected term is calculated as a weighted average of the estimated time to IPO as of the measurement date and the historical average term of options subject to the agreement which were vested and expired or were exercised. Volatility is based on the historical volatility of certain public entities that are similar to the Company as the Company does not have sufficient historical transactions of its own shares on which to base expected volatility. Significant increases (decreases) in the fair value of the Company’s stock price would result in a significantly larger (smaller) fair value liability measurement. Significant increases (decreases) in the expected term would result in a larger (smaller) fair value liability measurement.

5. Financial Statement Components

Accounts receivable, net of allowance for doubtful accounts consisted of the following:



	December 31, 2016			September 30, 2017
Trade accounts receivable	$	31,734		$	40,351
Unbilled accounts receivable	7,368			7,859
Allowance for doubtful accounts	(22,571		)	(30,040		)
Other accounts receivable	307			532
Total accounts receivable, net	$	16,838		$	18,702

Accounts receivable are stated at realizable value, net of an allowance for doubtful accounts. The allowance for doubtful accounts is based on management’s assessment of the collectability of its accounts receivable. The Company regularly reviews the composition of the accounts receivable aging, historical bad debts, changes in payment patterns, customer creditworthiness and current economic trends. If the financial condition of customers were to deteriorate, resulting in their inability to make required payments, additional provisions for doubtful accounts would be required and would increase bad debt expense. Management has evaluated the collectability of trade accounts receivable and determined that allowances of approximately $22,571 and $30,040 for uncollectible accounts and customer balances that are disputed were required as of December 31, 2016 and September 30, 2017, respectively. The allowance for doubtful accounts primarily relates to billings for CABS services where collectability was not probable. A roll forward of the components of the allowance for doubtful accounts for the three and nine months ended September 30, 2016 and 2017 are as follows:

10. Redeemable Convertible Preferred Stock and Stockholders’ Deficit

On October 19, 2017, the Company’s Board of Directors approved, and on October 23, 2017 the Company effected, a 2.50-to-1 split of its common stock. In connection with the common stock split, each share of outstanding common stock, option to purchase common stock and warrant to purchase common stock was increased to 2.50 shares of common stock and the exercise price of each outstanding option or warrant to purchase common stock was proportionately decreased. The stock split has been reflected retrospectively in these condensed consolidated financial statements. In connection with the stock split, the conversion ratio of each share of outstanding redeemable convertible preferred stock was also adjusted such that each share of outstanding redeemable convertible preferred stock converts into 2.50 shares of Old Class A common stock after the 2.50-to-1 split.

Table of Contents

Redeemable Convertible Preferred Stock

As of December 31, 2016 and September 30, 2017, 710,000 shares of redeemable convertible preferred stock ("Series A preferred stock") were issued and outstanding. The holders of Series A preferred stock shall be entitled to cast the number of votes equal to the number of whole shares of common stock into which the shares of Series A preferred stock are convertible as of the record date for determining stockholders entitled to vote on such matter. Holders of Series A preferred stock shall vote together with the holders of common stock as a single class.

Each share of Series A preferred stock shall be convertible, at the option of the shareholder, into such number of fully paid and non-assessable shares of common stock as is determined by dividing the Series A original issue price by the Series A conversion price in effect at the time of the conversion. The Series A conversion price was initially equal to $30.8358 and is subject to adjustment related to dilutive transactions. As a result of the stock split referred to above, the conversion ratio of each share of outstanding preferred stock also was adjusted subsequent to September 30, 2017, such that each share of outstanding preferred stock converts into 2.50 shares of Old Class A common stock at a conversion price of $12.3343.

Common Stock

As of December 31, 2016 and September 30, 2017, the Company had two classes of common stock: (1) Old Class A common stock and (2) Old Class B common stock. The Old Class A common stock had one vote per share and the Old Class B common stock was non-voting.

As of December 31, 2016 and September 30, 2017, 11,779,975 and 11,811,480 shares of Old Class A common stock were issued and outstanding at $0.001 par value per share, respectively.

As of December 31, 2016 and September 30, 2017, 18,590 and 34,840 shares of Old Class B common stock were issued and outstanding at $0.001 par value per share, respectively.

Pursuant to the Company’s second amended and restated certificate of incorporation and the effectiveness of its second amended and restated bylaws, which were effective on November 9, 2017 (i) each share of Old Class A common stock, including those shares of Old Class A common stock issued upon the conversion of then-outstanding Series A preferred stock, was reclassified as one share of New Class B common stock, with each share of New Class B common stock having ten votes per share, (ii) each share of Old Class B common stock was reclassified as one share of New Class A common stock, with each share of New Class A common stock having one vote per share. Subsequent to the effectiveness of the Company’s second amended and restated certificate of incorporation, the Company’s common stock consists of 120,000,000 authorized shares, par value $0.001 per share, of which the authorized New Class A common stock will consist of 100,000,000 shares and the authorized New Class B common stock will consist of 20,000,000 shares.

On November 9, 2017, the Series A preferred stock was converted at the option of the holder into 1,775,000 shares of New Class B common stock.

Stock Purchase Warrants

As of December 31, 2016 and September 30, 2017, a total of 64,691 shares of common stock were reserved for the issuance of stock purchase warrants.

11. Stock Based Compensation

2001 and 2010 Stock Option Plans

During 2001, the Company adopted the Bandwidth Inc. Stock Option Plan (the 2001 Plan). As of July 26, 2010, the Company adopted the 2010 Equity Compensation Plan (the 2010 Plan). On August 24, 2017, the 2010 Plan was amended to provide for a total of 3,466,275 shares of common stock reserved for issuance under the 2010 Plan.

Eligible plan participants include employees, directors and consultants. The 2001 Plan and the 2010 Plan each permit the granting of incentive stock options and non-qualified stock options.

The terms of the stock option grants are determined by the Company’s Board of Directors. The Company’s stock options vest based on terms in the stock option agreements, which is generally over four years. The stock options have a contractual life of ten years.

The fair value of options granted is estimated on the date of grant using the Black-Scholes-Merton option pricing model based on the assumptions in the table below:



	Three Months Ended September 30,		Nine Months Ended September 30,
	2016	2017	2016	2017
Expected dividend yield	0%	0%	0%	0%
Expected stock price volatility	44%	47%-49%	44%	44%-49%
Average risk-free interest rate	1.3%	1.9%	1.3%–1.6%	1.9%–2.3%
Expected life	6.2 years	6.2 years	6.2 years	6.2 years
Fair value of common stock	$9.57	$18.40-$20.83	$9.57	$9.60-$20.83

The Company uses the simplified method for purposes of determining the expected life of the options. The risk-free interest rate is based on the U.S. Treasury rates at the date of grant with maturity dates approximately equal to the expected life at the grant date. Volatility is based on the historical volatility of certain public entities that are similar to the Company, as the Company does not have sufficient historical transactions of its own shares on which to base expected volatility. The Company historically has not issued any dividends and does not expect to in the future.

The following summarizes the stock option activity for the periods presented:

Options vested and expected to vest as of September 30, 2017	3,640,526		$	6.85	4.60	$	51,092

Aggregate intrinsic value represents the total pre-tax intrinsic value, which is computed based on the difference between the option exercise price and the estimated fair value of the Company’s common stock. This amount changes based on the fair value of the Company’s stock.

The weighted average grant-date fair value of stock options granted was $4.03 and $4.04 for the three and nine months ended September 30, 2016, and $9.45 and $7.48 for the three and nine months ended September 30, 2017 respectively.

The total estimated grant date fair value of options vested was $188 and $1,900 for the three and nine months ended September 30, 2016, respectively, and $443 and $1,070 for the three and nine months ended September 30, 2017, respectively.

The Company recognized total stock-based compensation expense in continuing operations as follows:



	Three Months Ended September 30,				Nine Months Ended September 30,
	2016		2017		2016		2017
Cost of revenue	$	17	$	17	$	45	$	57

General and administrative(1)	161		503		804		821
Total	$	245	$	612	$	1,099	$	1,102

________________________

(1) On September 1, 2017, the Company reached a separation agreement with one of its executives. The agreement resulted in a modification of the former employee's 194,234 outstanding options to purchase common stock to accelerate the vesting period and extend the exercise period, which resulted in the recognition of $394 in additional stock compensation expense for the three months and nine months ended September 30, 2017.

The Company will recognize $2,191 of compensation cost in the future for stock-based employee compensation over the weighted-average of 2.7 years for stock options granted before September 30, 2017.

The Company incurred rent expense of $666 and $1,512 for the three and nine months ended September 30, 2016, respectively, and $1,034 and $2,414 for the three and nine months ended September 30, 2017, respectively, which is included in general and administrative expenses in the condensed consolidated statements of operations and comprehensive income.

In conjunction with the Spin-Off, the Company signed a Facilities Service Agreement with Republic in which the Company agreed to sub-lease 40,657 square feet of office space to Republic. The sub-lease is non-cancellable and extends to May 2022. The Company recorded a reduction of rent expense of $251 and $697 for the three and nine months ended September 30, 2017, respectively, which is included in general and administrative expenses in the condensed consolidated statements of operations and comprehensive income. No sub-lease payments were received for the nine months ended September 30, 2016 due to the Spin-Off having an effective date of November 30, 2016.

Contractual Obligations

On October 25, 2015, the Company entered into an agreement with a telecommunications service provider. The service agreement requires the Company to pay a monthly recurring charge beginning on January 1, 2016 associated with the services received. The service agreement is non-cancellable and contains annual minimum commitments of $1,200 to be fulfilled over five years or for as long as the Company continues to receive services from this vendor. In addition, the Company has other non-cancellable purchase obligations totaling $5,308 as of September 30, 2017, which consists primarily of network equipment to be received in less than one year.

Legal Matters

The Company is involved as a defendant in various lawsuits alleging that the Company failed to bill, collect and remit certain taxes and surcharges associated with the provision of 911 services pursuant to applicable laws in various jurisdictions. In August 2016, the Company received a Civil Investigative Demand from the Consumer Protection Division of the North Carolina Department of Justice, though no formal complaint has been filed in connection with that investigation. The North Carolina Department of Justice is investigating the billing, collection and remission of certain taxes and surcharges associated with 911 service pursuant to applicable laws of the State of North Carolina.

In April 2016, the Company filed counterclaims against MCI Communications Services, Inc. d/b/a Verizon Business and Verizon Select Services, Inc. (collectively, “Verizon”) in the United States District Court for the Northern District of Texas. The Company is pursuing collection of unpaid intercarrier compensation charges for providing switched access services related to the exchange of telecommunications traffic with Verizon entities across the United States. As of October 27, 2017, Verizon has asserted a counterclaim against the Company. The Company intends to contest such counterclaim vigorously. Verizon’s prior September 2014 complaint against the Company and other defendants regarding intercarrier compensation charges for providing switched access services related to the exchange of telecommunications traffic has been dismissed without prejudice, but remains subject to appeal.

While the results of these legal proceedings cannot be predicted with certainty, in the opinion of management, the ultimate resolution of these matters will not have a material adverse effect on the Company’s financial position or results of operations.

13. Employee Benefit Plan

The Company sponsors a defined contribution 401(k) plan which allows eligible employees to defer a portion of their compensation. The Company, at its discretion, may make matching contributions. The Company made matching contributions of $161 and $543 for the three and nine months ended September 30, 2016, respectively, and $181 and $596 for the three and nine months ended September 30, 2017, respectively.

14. Income Taxes

At the end of each interim reporting period, the Company determines the income tax provision by using an estimate of the annual effective tax rate, adjusted for discrete items occurring in the quarter. The Company’s effective tax rate was 3.3% and 35.5% for the three months ended September 30, 2016 and September 30, 2017, respectively, compared to 3.4% and 37.2% for the nine months ended September 30, 2016 and September 30, 2017, respectively. The difference in tax rate for the three and nine months ended September 30, 2016, compared to the three and nine months ended September 30, 2017, is because the Company had a full valuation allowance for the nine months ended September 30, 2016. The effective income tax rate reflects the effect of federal and state income taxes and the permanent impacts of differences in book and tax accounting. The Company’s effective tax rate for this period is higher than the U.S. federal statutory rate of 34% primarily due to state taxes.

15. Related Parties

In connection with the Spin-Off on November 30, 2016, the Company and Republic entered into certain agreements in order to govern the ongoing relationships between the two companies after the Spin-Off and to provide for an orderly transition. The agreements include a Transition Services Agreement, Facilities Sharing Agreement, Tax Sharing Agreement, and Master Services Agreement. The equity holders of Bandwidth are comprised of substantially the same individuals and entities that are the equity owners of Republic. The Company has determined the equity owners of Republic are related parties of Bandwidth. The Company has certain involvement with Republic via ongoing services arrangements, with these ongoing services arrangements creating a variable interest in Republic. The Company assessed the relationship with Republic under guidance for variable interest entities. Because investors in Republic have disproportionate voting rights, the Company concluded that Republic is a variable interest entity (“VIE”) but Bandwidth is not a primary beneficiary. The Company’s maximum exposure to loss relating to this variable interest entity is limited to amounts due under the service agreements between the Company and Republic.

For the three and nine months ended September 30, 2017, the Company received net compensation under the Transition Services Agreement of $37 and $548, respectively. In addition, there was approximately $35 due from Republic under the Transition Services Agreement as of September 30, 2017, which was recorded within accounts receivable in the accompanying condensed consolidated balance sheet.

Table of Contents

For the three and nine months ended September 30, 2017, the Company received rental payments under the Facilities Sharing Agreement of $251 and $697, respectively, which is included in general and administrative expenses in the condensed consolidated statements of operations and comprehensive income. No amounts were due to the Company under the Facilities Sharing Agreement as of December 31, 2016 and September 30, 2017.

There are no amounts outstanding or payable under the Tax Sharing Agreement as of December 31, 2016 and September 30, 2017.

During the three and nine months ended September 30, 2017, the Company provided telecommunication service under the Master Services Agreement to Republic of $550 and $1,623, respectively. The Company recognized such amounts as revenue in the accompanying condensed consolidated statement of operations and comprehensive income. In addition, there was approximately $193 due from Republic under the Master Services Agreement as of September 30, 2017, which was recorded within accounts receivable in the accompanying condensed consolidated balance sheet.

16. Basic and Diluted Income (Loss) per Common Share

The Company uses the two-class method to compute net income per common share, because it has issued securities, other than common stock, that contractually entitle the holders to participate in dividends and earnings. These participating securities include the Company’s redeemable convertible preferred stock which have non-forfeitable rights to participate in any dividends declared on the Company’s common stock. The two-class method requires earnings for the period to be allocated between common stock and participating securities based upon their respective rights to receive distributed and undistributed earnings.

Under the two-class method, for periods with net income, basic net income per common share is computed by dividing the net income attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Net income attributable to common stockholders is computed by subtracting from net income the portion of current period earnings that the participating securities would have been entitled to receive pursuant to their dividend rights had all of the period’s earnings been distributed. No such adjustment to earnings is made during periods with a net loss, as the holders of the participating securities have no obligation to fund losses.

Diluted net income (loss) per common share is computed under the two-class method by using the weighted average number of shares of common stock outstanding, plus, for periods with net income attributable to common stockholders, the potential dilutive effects of stock options and warrants. The Company analyzed the potential dilutive effect of any outstanding dilutive securities under the “if-converted” method and treasury-stock method when calculating diluted earnings per share, in which it is assumed that the outstanding participating securities convert into common stock at the beginning of the period or date of issuance, if later. The Company reports the more dilutive of the approaches (two-class or “if-converted”) as its diluted net income per share during the period.

17. Subsequent Events

On October 6, 2017, the Company was notified that certain additional jurisdictions within the state of Georgia intend to initiate legal proceedings against the Company in response to allegations that the Company failed to bill, collect and remit certain taxes and surcharges associated with the provision of 911 services. On October 13, 2017, the Company signed a tolling agreement with certain additional jurisdictions regarding such allegations.

On October 19, 2017, the Company approved, and on October 23, 2017, the Company amended its Certificate of Incorporation allowing the Company to change the number of authorized shares as follows: (i) 30,000,000 shares of common stock, $0.001 par value per share of which 25,000,000 shares were designated as Old Class A common stock, and of which 5,000,000 shares were designated as Old Class B common stock and (ii) 1,200,000 shares of preferred stock, $0.001 par value.

On October 19, 2017, the Company’s Board of Directors approved, and on October 23, 2017, the Company effected, a 2.50-to-1 split of its common stock. In connection with the common stock split, each share of outstanding common stock, option to purchase common stock and warrant to purchase common stock was increased to 2.50 shares of common stock and the exercise price of each outstanding option or warrant to purchase common stock was proportionately decreased. The stock split has been reflected retrospectively in these consolidated financial statements. In connection with the stock split, the conversion ratio of each share of outstanding Series A preferred stock was also adjusted such that each share of outstanding Series A preferred stock converts into 2.50 shares of Old Class A common stock after the 2.50-to-1 split.

On October 27, 2017, the United States District Court for the Northern District of Texas granted Verizon’s motion to permit it to assert counterclaims against the Company in connection with the ongoing complaint related to unpaid intercarrier compensation charges.

On November 9, 2017, the Company filed a second amended and restated certificate of incorporation. As a result of this amendment, the Company’s common stock consists of 120,000,000 authorized shares, par value $0.001 per share, of which the authorized New Class A common stock consists of 100,000,000 shares and the authorized New Class B common stock consists of 20,000,000 shares.

On November 10, 2017, the Company sold 4,000,000 shares of its New Class A common stock at a public offering price of $20.00 per share. The Company received proceeds of $74,400, after deducting underwriting discounts and commissions of $5,600. Immediately prior to the pricing of the IPO on November 9, 2017, all shares of the Company’s then-outstanding Series A preferred stock converted into an aggregate of 1,775,000 shares of New Class B common stock and an aggregate of 11,811,480 shares of Old Class A common stock converted into New Class B common stock for a total of 13,586,480 shares outstanding of New Class B common stock. In addition, an aggregate of 34,840 shares of Old Class B common stock converted into New Class A common stock and warrants exercisable into shares of Old Class A common stock became exercisable into shares of New Class B common stock.

On November 10, 2017 as a result of the Company's IPO the liability related to the Shareholders' anti-dilutive arrangement was terminated under the original terms of the agreement.

Table of Contents

On November 14, 2017, the Company paid in full its outstanding term loan of $38,500 with the proceeds from the IPO and wrote-off the unamortized loan fees associate with the term loan. The revolving loan remains in effect.

On November 28, 2017, the Underwriters exercised their option to sell 162,991 shares of the Company's Class A common stock under the options granted to them under the Underwriting Agreement. As a result of this transaction, shares of New Class B common stock held by selling stockholders were converted into New Class A common stock. There were no additional proceeds to the Company as a result of the shares of New Class A common stock sold by the selling stockholders.

Item 2.	Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and related notes that are included elsewhere in this Quarterly Report Form 10-Q. This discussion contains forward-looking statements based upon current plans, expectations and beliefs that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under “Risk Factors” in this Quarterly Report Form 10-Q. Our fiscal year ends on December 31.

Overview

We are a leading cloud-based communications platform for enterprises in the United States. Our solutions include a broad range of software application programming interfaces ("APIs') for voice and text functionality and our owned and managed, purpose- built internet protocol ("IP') voice network, one of the largest in the nation. Our sophisticated and easy-to-use software APIs allow enterprises to enhance their products and services by incorporating advanced voice and text capabilities. Companies use our platform to more frequently and seamlessly connect with their end users, add voice calling capabilities to residential Internet of Things ("IoT') devices, offer end users new mobile application experiences and improve employee productivity, among other use cases. By owning and operating a capital-efficient, purpose-built IP voice network, we are able to offer advanced monitoring, reporting and analytics, superior customer service, dedicated operating teams, personalized support, and flexible cost structures. Over the last ten years, we have pioneered the CPaaS space through our innovation-rich culture and focus on empowering enterprises with end-to-end communications solutions.

Our voice software APIs allow enterprises to make and receive phone calls and create advanced voice experiences. Integration with our purpose-built IP voice network ensures enterprise-grade functionality and secure, high-quality connections. Our messaging software APIs provide enterprises with advanced tools to connect with end users via messaging. Our customers also use our solutions to enable 911 response capabilities, real-time provisioning and activation of phone numbers and toll-free number messaging.

We are the only CPaaS provider in the industry with our own nationwide IP voice network, which we have purpose-built for our platform. Our network is capital-efficient and custom-built to support the applications and experiences that make a difference in the way enterprises communicate. Since a communications platform is only as strong as the network that backs it, we believe our network provides a significant competitive advantage in the control, quality, pricing power and scalability of our offering. We are able to control the quality and provide the support our customers expect, as well as efficiently meet scalability and cost requirements.

For the three months ended September 30, 2017 and 2016, total revenue was $41.3 million and $38.6 million, respectively. CPaaS revenue for the three months ended September 30, 2017 and 2016 was $33.4 million and $30.2 million, respectively, representing a growth rate of 10%. Net income for the three months ended September 30, 2017 and 2016 was $1.6 million and $3.3 million, respectively. The number of active CPaaS customer accounts increased to 918 as of September 30, 2017, up 18% from 781 active CPaaS customer accounts as of September 30, 2016.

Key Performance Indicators

We monitor the following KPIs to help us evaluate our business, identify trends affecting our business, formulate business plans, and make strategic decisions. We believe the following KPIs are useful in evaluating our business:



	Three Months Ended September 30,
	2016			2017
	(Dollars in thousands)
Number of Active CPaaS customers (as of period end)	781			918
Dollar-based net retention rate	112		%	105		%
Net income	$	3,288		$	1,634
Adjusted EBITDA	$	6,201		$	5,180
Net Cash provided by operating activities from continuing operations	$	2,174		$	4,766
Free cash flow	$	1,317		$	2,652

Number of Active CPaaS Customer Accounts

We believe that the number of active CPaaS customer accounts is an important indicator of the growth of our business, the market acceptance of our platform and our future revenue trends. 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. Customers who pay after using our platform and customers that have credit balances are included in the number of active CPaaS customer accounts. Customers from our Other segment are excluded in the number of active CPaaS customer accounts, unless they are also CPaaS customers.

In the three months ending September 30, 2016 and 2017 revenue from active CPaaS customer accounts represented approximately 99% of total CPaaS revenue in each period.

Dollar-based Net Retention Rate

Our ability to drive growth and generate incremental revenue depends, in part, on our ability to maintain and grow our relationships with our existing customers that generate CPaaS revenue and seek to increase their use of our platform. We track our performance in this area by measuring the dollar-based net retention rate for our customers who generate CPaaS revenue. 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.

Table of Contents

Our dollar-based net retention rate increases when such customers increase usage of a product, extend usage of a product to new applications or adopt a new product. Our dollar-based net retention rate decreases when such customers cease or reduce usage of a product or when we lower prices on our solutions. As our customers grow their business and extend the use of our platform, they sometimes create multiple customer accounts with us for operational or other reasons. As such, when we identify a significant customer organization (defined as a single customer organization generating more than 1% of CPaaS revenue in a quarterly reporting period) that has created a new CPaaS customer, this new customer is tied to, and CPaaS revenue from this new customer is included with, the original CPaaS customer for the purposes of calculating this metric.

Key Components of Statements of Operations

Revenue

We generate a majority of our revenue from our CPaaS segment. CPaaS revenue is derived from voice usage, phone number services, 911-enabled phone number services, messaging services and other services. We generate a portion of our CPaaS revenue from usage-based fees which include voice calling and messaging services. For the three months ended September 30, 2016 and 2017, we generated 57% and 58% of our CPaaS revenue, respectively, from usage-based fees. We also earn monthly fees from services such as phone number services and 911 access service. For the three months ended September 30, 2016 and 2017, we generated 40% of our CPaaS revenue in each period from monthly per unit fees.

The remainder of our revenue is generated by our Other segment. Other revenue is composed of revenue earned from our legacy services and indirect revenue. Other revenue as a percentage of total revenue is expected to continue to decline over time.

We recognize accounts receivable at the time the customer is invoiced. Additionally, we record a receivable and revenue for unbilled revenue if the services have been delivered and are billable in subsequent periods. Unbilled revenue made up 44% and 42% of outstanding accounts receivable, net of allowance for doubtful accounts as of September 30, 2016 and September 30, 2017, respectively.

Cost of Revenue and Gross Margin

CPaaS cost of revenue consists primarily of fees paid to other network service providers from whom we buy services such as minutes of use, phone numbers, messages, porting of customer numbers and network circuits. Cost of revenue also contains costs related to support of our IP voice network, web services, cloud infrastructure, capacity planning and management, rent for network facilities, software licenses, hardware and software maintenance fees and network engineering services. Personnel costs (including non-cash stock-based compensation expenses) associated with personnel who are responsible for the delivery of services, operation and maintenance of our communications network, and customer support as well as, third-party support agreements and depreciation of network equipment, amortization of internally developed software and gain (loss) on disposal of property and equipment are also included in cost of revenue.

Table of Contents

Other cost of revenue consists of costs supporting non-CPaaS services including leased circuit costs paid to third party providers, internet connectivity expenses, minutes of use, direct operations, contractors, regulatory fees, surcharges and other pass-through costs and software and hardware maintenance fees.

Gross margin is calculated by subtracting cost of revenue from revenue, divided by total revenue, expressed as a percentage. Our cost of revenue and gross margin have been, and will continue to be, affected by several factors, including the timing and extent of our investments in our network, our ability to manage off-network minutes of use and messaging costs, the product mix of revenue, the timing of amortization of capitalized software development costs and the extent to which we periodically choose to pass on any cost savings to our customers in the form of lower usage prices.

Operating Expenses

The most significant components of operating expenses are personnel costs, which consist of salaries, benefits, bonuses, and stock-based compensation expenses. We also incur other non-personnel costs related to our general overhead expenses, including facility expenses, software licenses, web services, depreciation and amortization of assets unrelated to delivery of our services. We expect that our operating expenses will increase in absolute dollars.

Research and Development

R&D expenses consist primarily of personnel costs (including non-cash stock-based compensation expenses), outsourced software development and engineering service and cloud infrastructure fees for staging and development of outsourced engineering services. We capitalize the portion of our software development costs in instances where we invest resources to develop software for internal use. We plan to continue to invest in R&D to enhance current product offerings and develop new services.

Sales and Marketing

Sales and marketing expenses consist primarily of personnel costs, including commissions for our sales employees and non-cash stock-based compensation expenses. Sales and marketing expenses also include expenditures related to advertising, marketing, our brand awareness activities, sales support and professional services fees.

We focus our sales and marketing efforts on creating sales leads and establishing and promoting our brand. We plan to continue to invest in sales and marketing in order to expand our CPaaS customer base by growing headcount, driving our go-to-market strategies, building brand awareness, advertising and sponsoring additional marketing events.

Table of Contents

General and Administrative

General and administrative expenses consist primarily of personnel costs, including stock-based compensation, for our accounting, finance, legal, human resources and administrative support personnel and executives. General and administrative expenses also include costs related to product management and reporting, customer billing and collection functions, information services, professional services fees, credit card processing fees, rent associated with our headquarters in Raleigh, North Carolina and our other offices, and depreciation and amortization. We expect that we will incur increased costs associated with supporting the growth of our business and to meet the increased compliance requirements associated with our transition to, and operation as, a public company.

Income Taxes

Our effective tax rate was 3.3% and 35.5% for the three months ended September 30, 2016 and September 30, 2017, respectively. The increase in our effective tax rate is due to the release of our valuation allowance against deferred tax assets in the fourth quarter of 2016.

Non-GAAP Financial Measures

We use adjusted EBITDA, Non-GAAP gross profit, Non-GAAP gross margin, Non-GAAP net income and free cash flow for financial and operational decision making and to evaluate period-to-period differences in our performance. Adjusted EBITDA, Non-GAAP gross profit, Non-GAAP gross margin, Non-GAAP net income and free cash flow are non-GAAP financial measures, which we believe are useful for investors in evaluating our overall financial performance. We believe these measures provide useful information about operating results, enhance the overall understanding of past financial performance and future prospects and allow for greater transparency with respect to key performance indicators used by management in its financial and operational decision making. For a reconciliation of each of the non-GAAP financial measures described below, see “Reconciliation of Non-GAAP Financial Measures.”

Adjusted EBITDA

We define adjusted EBITDA as net income or losses from continuing operations, 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, if any;


•	loss (gain) from disposal of property and equipment; and


•	change in fair value of financial instruments, including any change in shareholders’ anti-dilutive arrangements.

Table of Contents

Adjusted EBITDA is a key measure used by management to understand and evaluate our core operating performance and trends, to generate future operating plans and to make strategic decisions regarding the allocation of capital. In particular, the exclusion of certain expenses in calculating adjusted EBITDA facilitates comparisons of our operating performance on a period-to-period basis.

Non-GAAP Gross Profit and Non-GAAP Gross Margin

GAAP defines gross profit as revenue less cost of revenue. Cost of revenue includes all expenses associated with our various service offerings as more fully described under the caption “Key Components of Statement of Operations-Cost of Revenue and Gross Margin.” We define Non-GAAP gross profit as gross profit after adding back the following items:


•	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 Non-GAAP 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 Non-GAAP gross profit by revenue, expressed as a percentage of revenue.

Management uses Non-GAAP gross profit and Non-GAAP gross margin to evaluate operating performance and to determine resource allocation among our various service offerings. We believe that Non-GAAP gross profit and Non-GAAP gross margin provide useful information to investors and others to understand and evaluate our operating results in the same manner as our management and board of directors and allows for better comparison of financial results among our competitors. Non-GAAP gross profit and Non-GAAP gross margin may not be comparable to similarly titled measures of other companies because other companies may not calculate Non-GAAP gross profit and Non-GAAP gross margin or similarly titled measures in the same manner as we do.

Non-GAAP Net Income

We define Non-GAAP net income as net income adjusted for certain items affecting period-to-period comparability. Non-GAAP net income excludes:


•	stock-based compensation;


•	change in fair value of shareholders’ antidilutive arrangement;


•	amortization of acquired intangible assets related to the Dash acquisition;

We believe Non-GAAP net income is a meaningful measure because by removing certain non-cash and other expenses we are able to evaluate our operating results in a manner we believe is more indicative of the current period's performance. We believe the use of Non-GAAP net income may be helpful to investors because it provides consistency and comparability with past financial performance, facilitates period-to-period comparisons of results of operations and assists in comparisons with other companies, many of which may use similar non-GAAP financial information to supplement their GAAP results.

Free Cash Flow

Free cash flow represents net cash provided by (used in) operating activities from continuing operations less net cash used in investing activities from continuing operations. 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, 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.

Table of Contents

For the three months ended September 30, 2017, total revenue increased by $2.7 million, or 7%, compared to the same period in 2016. CPaaS revenue increased by $3.1 million, or 10%, compared to the same period in 2016. As a percentage of total revenue, CPaaS revenue increased from 78% to 81% from the three months ended September 30, 2016 to September 30, 2017. The increase in CPaaS revenue was primarily attributable to an increase in the usage of all our service offerings, particularly our voice and messaging usage, which accounted for $5.6 million of the increase in CPaaS revenue, and additionally our phone number services and 911-enabled phone number services, which accounted for $0.6 million of the increase in CPaaS revenue. This overall increase in CPaaS revenue was partially offset by $3.1 million related to pricing decreases that we have implemented over time with our customers in the form of lower usage prices to increase the reach and scale of our platform. The changes in usage and price in the three months ended September 30, 2017 were reflected in our dollar-based net retention rate of 105%. The decline in the dollar-based net retention rate in the three months ended September 30, 2017 was primarily due to a strategic decision to no longer service a particular customer. The increase in usage was also attributable to an 18% increase in the number of active CPaaS customer accounts, from 781 as of September 30, 2016 to 918 as of September 30, 2017. In addition, revenue from new CPaaS customers contributed $1.5 million, or 5%, to CPaaS revenue for the three months ended September 30, 2017 compared to $1.1 million, or 4%, to CPaaS revenue in the same period in 2016. Other revenue decreased by $0.4 million, driven by the expected decline in legacy services of $0.7 million, partially offset by an increase in indirect revenue of $0.3 million.

Total gross margin	44%		45%		1%

For the three months ended September 30, 2017, total cost of revenue increased by $1.1 million and total gross margin increased by 1% due to improved CPaaS gross margin. CPaaS cost of revenue increased by $1.1 million, or 6%. This increase in cost of revenue was attributable to increased customer usage and network costs, partially offset by a decline in unit costs for 911, phone numbers and voice services. CPaaS cost of revenue increases were comprised of $0.5 million increase in cost of voice minutes, $0.4 million increase in network costs, $0.1 million increase in cost of phone numbers, and a $0.1 million increase in cost of messaging. CPaaS gross margin increased from 40% for the three months ended September 30, 2016 to 42% for the three months ended September 30, 2017. Excluding the impact of depreciation of $1.2 million for the three months ended September 30, 2016 and depreciation of $1.2 million for the three months ended September 30, 2017, CPaaS Non-GAAP gross margin would have been 44% and 46% for the three months ended September 30, 2016 and 2017, respectively, and total Non-GAAP gross margin would have been 47% and 48% for the three months ended September 30, 2016 and 2017, respectively.

This increase was partially due to an increase in headcount costs due to severance related to a separation agreement with one of the company's executives. The other portion of the increase was due to increased non-headcount expenses for hosted software costs, increased bad debt expense, and increased taxes.

Interest Expense, Net

For the three months ended September 30, 2017 interest expense increased by $0.2 million, compared to the same period in 2016 due to an increased balance outstanding under our credit facility that we entered into in November 2016.

As a percentage of total revenue, CPaaS revenue increased from 77% to 80% from the nine months ended September 30, 2016 to September 30, 2017.

Critical Accounting Policies and Significant Judgments and Estimates

Our condensed consolidated financial statements are prepared in accordance with GAAP. The preparation of these financial statements requires our management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs, and expenses and related disclosures. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these judgments and estimates under different assumptions or conditions and any such differences may be material.

We believe that the assumptions and estimates associated with revenue recognition and deferred revenue, stock-based compensation, the valuation of goodwill and intangible assets, internal-use software development costs, income taxes and other contingencies have the greatest potential impact on our condensed consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates.

There have been no material changes to our critical accounting policies and significant judgments and estimates as compared to the critical accounting policies and significant judgments and estimates disclosed in the final prospectus for our IPO filed with the SEC on November 13, 2017 pursuant to Rule 424(b)(1) under the Securities Act.

Recently Issued Accounting Guidance

See Note 2 of the notes to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for a summary of recent accounting pronouncements not yet adopted.

JOBS Act Accounting Election

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”).

Section 107 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to use the extended transition period for complying with new or revised accounting standards under Section 102(b)(1) of the JOBS Act. This election allows us to delay the adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private companies. As a result of this election, our financial statements may not be comparable to companies that comply with public company effective dates.

We also intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,” including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We may take advantage of these exemptions for so long as we are an “emerging growth company.”

We will remain an emerging growth company until the earlier of (1) December 31, 2022 (the last day of the fiscal year following the fifth anniversary of our initial public offering), (2) the last day of the fiscal year in which we have total annual gross revenue of at least $1.07 billion, (3) the last day of the fiscal year in which we are deemed to be a “large accelerated filer,” as defined in the Exchange Act, and (4) the date on which we have issued more than $1.0 billion in nonconvertible debt during the prior three-year period. Any reference herein to “emerging growth company” has the meaning ascribed to it in the JOBS Act.

Item 3.	Quantitative and Qualitative Disclosures about Market Risk

We are exposed to certain market risks in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily the result of fluctuations in interest rates and, to a lesser extent, inflation.

Interest Rate Risk

Our primary exposure to market risk relates to interest rate changes. We had cash and cash equivalents totaling $5.4 million as of September 30, 2017, which were held for working capital purposes. Our cash and cash equivalents are comprised primarily of interest bearing checking accounts.

Such interest-earning instruments carry a degree of interest rate risk. To date, fluctuations in interest income have not been significant. The primary objective of our investment activities is to preserve principal while maximizing income without significantly increasing risk. We do not enter into investments for trading or speculative purposes and have not used any derivative financial instruments to manage our interest rate risk exposure. Due to the short-term nature of our investments, we have not been exposed to, nor do we anticipate being exposed to, material risks due to changes in interest rates.

We had debt totaling $38.5 million as of September 30, 2017. Our debt is comprised of $38.5 million outstanding under our term loan and no amount outstanding on the revolving line of credit. The revolving line of credit had an interest rate based on the 1-month LIBOR rate plus 225 basis points as of September 30, 2017. The term loan had an interest rate based on the 3-month LIBOR rate plus 225 basis points. A one-eighth percentage point increase or decrease in the applicable rate for our credit facility (assuming the revolving portion of the credit facility is fully drawn) would have an annual impact of $0.1 million on cash interest expense.

Foreign Currency Risk

Our customers consume our services primarily in the United States. Our revenue and expenses are denominated in U.S. dollars and as a result we have no foreign currency risk.

Inflation

We do not believe inflation has had a material effect on our business, financial condition or results of operations. We continue to monitor the impact of inflation in order to minimize its effects through pricing strategies, productivity improvements and cost reductions. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm our business, financial condition and results of operations.

Item 4. Controls and Procedures

Evaluation of disclosure controls and procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, have evaluated our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures are designed at a reasonable assurance level and are effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in internal control over financial reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act during the quarter ended September 30, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent limitation on the effectiveness of internal control

The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, any system of internal control over financial reporting, including ours, no matter how well designed and operated, can only provide reasonable, not absolute assurances. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business, but cannot assure you that such improvements will be sufficient to provide us with effective internal control over financial reporting.

PART II -- OTHER INFORMATION

Item 1. Legal Proceedings

In April 2014, Phone Recovery Services, LLC (“Phone Recovery Services”) filed a complaint against us in the Superior Court of the District of Columbia. The complaint alleges that we failed to bill, collect and remit certain taxes and surcharges associated with the provision of 911 services pursuant to applicable laws of the District of Columbia. In November 2015, the Superior Court of the District of Columbia dismissed Phone Recovery Services’ complaint with prejudice. Phone Recovery Services subsequently appealed, and we are currently awaiting a decision regarding Phone Recovery Services’ appeal.

Phone Recovery Services, acting or purporting to act on behalf of applicable jurisdictions, or the applicable county or city itself, has filed similar lawsuits against us and/or one of our subsidiaries in the Superior Court of the State of Rhode Island, the Court of Common Pleas of Allegheny County, Pennsylvania and the District Court of Ramsey County, Minnesota that are currently in various stages of litigation. The case in Ramsey County, Minnesota was dismissed in November 2016; in August 2017, the Minnesota Court of Appeals affirmed that dismissal. On September 5, 2017, Phone Recovery Services filed a notice of appeal to the Minnesota Supreme Court. To date, we have not received any material adverse decision in connection with those matters.

We face similar lawsuits brought directly by various state and local governments alleging underpayment of 911 taxes and surcharges, although we understand that Phone Recovery Services is working in conjunction with each state or local government as a consultant on a contingency basis. The following county or municipal governments have named us in lawsuits associated with the collection and remittance of 911 taxes and surcharges: Birmingham Emergency Communications District, Alabama (the "Alabama Case"); Clayton County, Cobb County, DeKalb County, Fulton County, Gwinnett County, Macon-Bibb County, Georgia and Columbus Consolidated Government, Georgia (collectively, the “Georgia Cases”); Cook County and Kane County Illinois; City of Chicago, Illinois; the State of Illinois (collectively, the “Illinois Case”); Beaver County, Berks County, Bucks County, Butler County, Chester Co., Clarion County, Cumberland County, Dauphin County, Delaware County, Lancaster County, Lebanon County, Mercer County, Somerset County, Washington County, Westmoreland County, and York County, Pennsylvania (collectively, the “Pennsylvania Cases”); and Charleston County, South Carolina. The complaints allege that we failed to bill, collect and remit certain taxes and surcharges associated with 911 service pursuant to applicable laws. A claim in the Alabama Case was partially dismissed in December 2017; Birmingham Emergency Communications District may timely appeal the partial dismissal of the claim. The Georgia Cases have been closed administratively during the appeal of a related case in the Georgia courts; the Georgia Cases may be reopened. We understand that Augusta-Richmond County, Bartow County, Chatham County, Cherokee County, City of Atlanta, City of Savannah, Forsyth County, Houston County and Spalding County, Georgia each intends to initiate legal proceedings against us with allegations substantially similar to those in the Georgia Cases. The Pennsylvania Case in Butler County, Pennsylvania was dismissed in August 2016; the Pennsylvania Cases have been stayed until the appeal of the dismissal of the Butler County, Pennsylvania Case is resolved. The Illinois Case was dismissed in December 2016; Phone Recovery Services timely filed a notice of appeal and the appeal is underway.

In August 2016, we received a Civil Investigative Demand from the Consumer Protection Division of the North Carolina Department of Justice, though no formal complaint has been filed in connection with that investigation. The North Carolina Department of Justice is investigating the billing, collection

and remission of certain taxes and surcharges associated with 911 service pursuant to applicable laws of the State of North Carolina.

We also have ongoing litigations against MCI Communications Services, Inc. d/b/a Verizon Business and Verizon Select Services, Inc. (collectively, “Verizon”) in the United States District Court for the Northern District of Texas. In April 2016, we filed counterclaims against Verizon. We are pursuing collection of unpaid intercarrier compensation charges for providing switched access services related to the exchange of telecommunications traffic with Verizon entities across the United States. Verizon has asserted counterclaims against us. We intend to contest the counterclaims vigorously. Verizon’s prior September 2014 complaint against us and other defendants regarding intercarrier compensation charges for providing switched access services related to the exchange of telecommunications traffic has been dismissed without prejudice, but remains subject to appeal.

Item 1A. Risk Factors

RISK FACTORS

In addition to the other information set forth in this quarterly report, you should carefully consider the factors discussed in “Risk Factors” in our registration statement on Form S-1 filed with the SEC on October 12, 2017, which could materially affect our business, financial condition or future results. There have been no material changes from the risk factors previously disclosed in that prospectus.

Item 2. Unregistered Sales of Equity Securities

Recent Sales of Unregistered Securities

On November 28, 2017, the Underwriters exercised their option to sell 162,991 shares of our Class A common stock under the options granted to them under the Underwriting Agreement. As a result of this transaction, shares of Class B common stock held by the selling stockholders were converted to Class A common stock resulting in 4,197,831 outstanding shares of Class A common stock and 13,423,489 of Class B common stock.

Use of Proceeds

On November 9, 2017, the Registration Statement on Form S-1 (File No. 333-220945) for our initial public offering of our Class A common stock was declared effective by the SEC. Shares of our Class A common stock began trading on the New York Stock Exchange on November 10, 2017.

The underwriters of our initial public offering were Morgan Stanley, KeyBank Capital Markets, Baird, Canaccord Genuity and JMP Securities. We paid to the underwriters of our initial public offering an underwriting discount totaling approximately $5.6 million. In addition, we incurred expenses of approximately $5.3 million which, when added to the underwriting discount, amount to total expenses of approximately$10.9 million. Thus, the net offering proceeds, after deducting underwriting discounts and offering expenses, were approximately $69.1 million. No payments were made to our directors or officers or their associates, holders of 10% or more of any class of our equity securities or any affiliates.

There has been no material change in the planned use of proceeds from the IPO from that described in the final prospectus filed with the SEC pursuant to Rule 424(b)(1) under the Securities Act on November
