Use of Non-GAAP Financial Measures BARK reports its financial results in accordance with GAAP. However, BARK's management believes that Adjusted EBITDA and Adjusted EBITDA margin, both non-GAAP financial measures, provide investors with additional useful information in evaluating its performance. Adjusted EBITDA and Adjusted EBITDA margin are financial measures that are not required by, or presented in accordance with GAAP. BARK believe that Adjusted EBITDA and Adjusted EBITDA margin, when taken together with its financial results presented in accordance with GAAP, provides meaningful supplemental information regarding its operating performance and facilitates internal comparisons of its historical operating performance on a more consistent basis by excluding certain items that may not be indicative of its business, results of operations or outlook. In particular, BARK believe that the use of Adjusted EBITDA and Adjusted EBITDA margin are helpful to its investors as it is a measure used by management in assessing the health of its business, determining incentive compensation and evaluating its operating performance, as well as for internal planning and forecasting purposes. Adjusted EBITDA and Adjusted EBITDA margin are presented for supplemental informational purposes only, have limitations as an analytical tool and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. Some of the limitations of Adjusted EBITDA and Adjusted EBITDA margin include that (1) the measures do not properly reflect capital commitments to be paid in the future, (2) although depreciation and amortization are non-cash charges, the underlying assets may need to be replaced and Adjusted EBITDA and Adjusted EBITDA margin do not reflect these capital expenditures, (3) the measures do not consider the impact of stock-based compensation expense, which is an ongoing expense for BARK and (4) the measures do not reflect other non-operating expenses, including interest expense. In addition, its use of Adjusted EBITDA and Adjusted EBITDA margin may not be comparable to similarly titled measures of other companies because they may not calculate Adjusted EBITDA or Adjusted EBITDA margin in the same manner, limiting its usefulness as a comparative measure. Because of these limitations, when evaluating BARK's performance, you should consider Adjusted EBITDA and Adjusted EBITDA margin alongside other financial measures, including its net income (loss) and other results stated in accordance with GAAP.
