According to Snap: "We define Adjusted EBITDA as net income (loss), excluding interest income; interest expense; other income (expense), net; income tax benefit (expense); depreciation and amortization; stock-based compensation expense and related payroll tax expense; and certain other non-cash or non-recurring items impacting net income (loss) from time to time. We consider the exclusion of certain non-cash and non-recurring expenses in calculating Adjusted EBITDA to provide a useful measure for period-to-period comparisons of our business and for investors and others to evaluate our operating results in the same manner as does our management. Additionally, we believe that Adjusted EBITDA is an important measure since we use third-party infrastructure partners to host our services and therefore we do not incur significant capital expenditures to support revenue-generating activities. See “Selected Financial Data — Non-GAAP Financial Measures” for additional information and a reconciliation of net loss to Adjusted EBITDA."
