performance of our core business. Because this non-GAAP financial measure is an important internal measure for us, we believe that the presentation of this non-GAAP financial measure provides analysts, investors, lenders and other third parties insight into our view and assessment of our ongoing operating performance. In addition, we believe that the presentation of this non-GAAP financial measure, when viewed with our results under GAAP and the accompanying reconciliation, provide supplementary information that may be useful to analysts, investors, lenders, and other third parties in assessing our performance and results from period to period. We report this non-GAAP financial measure to portray the results of our major operations prior to considering certain income statement elements. This non-GAAP financial measure should be considered in addition to, and not as a substitute for, or superior to, net income or other financial measures calculated in accordance with GAAP.
Adjusted EBITDA represents GAAP net income adjusted to exclude interest expense, interest income, the benefit from or provision for income taxes, depreciation, amortization, and stock-based compensation. Adjusted EBITDA, as used by us, may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies. Please see the section of this press release titled “Reconciliation of GAAP Net Income to Adjusted EBITDA” for a reconciliation of non-GAAP adjusted EBITDA to its most directly comparable GAAP measure.
There are several limitations related to the use of adjusted EBITDA rather than net income, which is the nearest GAAP equivalent, such as:
| ● | adjusted EBITDA excludes depreciation and amortization, and, although these are non-cash expenses, the assets being depreciated or amortized may have to be replaced in the future, the cash requirements for which are not reflected in adjusted EBITDA; |
| ● | we exclude stock-based compensation expense from adjusted EBITDA although (a) it has been, and will continue to be for the foreseeable future, a significant recurring expense for our business and an important part of our compensation strategy and (b) if we did not pay out a portion of our compensation in the form of stock-based compensation, the cash salary expense included in operating expenses would be higher, which would affect our cash position; |
| ● | adjusted EBITDA does not reflect changes in, or cash requirements for, working capital needs; |
| ● | adjusted EBITDA does not reflect the benefit from or provision for income taxes or the cash requirements to pay taxes; and |
| ● | adjusted EBITDA does not reflect historical cash expenditures or future requirements for capital expenditures or contractual commitments. |
The Company has not provided a reconciliation of its full-year 2021 guidance for non-GAAP adjusted EBITDA to the most directly comparable forward-looking GAAP measure because it is unable to predict, without unreasonable efforts, the timing and amount of items that would be included in such a reconciliation, including, but not limited to, stock-based compensation expense. These items are uncertain and depend on various factors that could have a material impact on GAAP net income for the guidance period.
