Non-GAAP Financial Measures
To supplement its consolidated financial statements, which are prepared and presented in accordance with GAAP, the company uses the following non-GAAP financial measures: adjusted EBITDA, non-GAAP net income, and non-GAAP EPS (collectively the “non-GAAP financial measures”). The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. The company uses these non-GAAP financial measures for financial and operational decision making and as a means to evaluate period-to-period comparisons. The company believes that they 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 metrics used by management in its financial and operational decision making. 

The company excludes the following items from one or more of its non-GAAP measures:

Stock-based compensation. The company excludes stock-based compensation because it is non-cash in nature and because the company believes that the non-GAAP financial measures excluding this item provide meaningful supplemental information regarding operational performance and liquidity. The company further believes this measure is useful to investors in that it allows for greater transparency to certain line items in its financial statements and facilitates comparisons to competitors’ operating results.

Amortization of acquired intangible assets. The company excludes amortization of acquired intangible assets because it is non-cash in nature and because the company believes that the non-GAAP financial measures excluding this item provide meaningful supplemental information regarding operational performance and liquidity. In addition, excluding this item from various non-GAAP measures facilitates internal comparisons to historical operating results and comparisons to competitors’ operating results. 

Income tax effect of non-GAAP adjustments. Excluding the income tax effect of non-GAAP adjustments from the provision for income taxes assists investors in understanding the tax provision related to those adjustments and the effective tax rate related to ongoing operations.

Assumed preferred stock conversion. As a result of the company’s initial public offering, all outstanding shares of preferred stock were automatically converted into shares of Class B common stock. Consequently, non-GAAP diluted net income per share has been calculated assuming the conversion of all outstanding shares of preferred stock into shares of Class B common stock. 

For more information on the non-GAAP financial measures, please see the “Reconciliation of GAAP to non-GAAP Financial Measures” table in this press release.  This accompanying table has more details on the GAAP financial measures that are most directly comparable to non-GAAP financial measures and the related reconciliations between these financial measures. Additionally, the company has not reconciled adjusted EBITDA guidance to net income guidance because it does not provide guidance for other income (expense) and provision for income taxes, which are reconciling items between net income (loss) and adjusted EBITDA. As items that impact net income (loss) are out of the company’s control and/or cannot be reasonably predicted, the company is unable to provide such guidance. Accordingly, a reconciliation to net income (loss) is not available without unreasonable effort.
