Use of non-GAAP metrics

In its earnings releases, Pulmonx explains that it uses non-GAAP financial measures such as Adjusted EBITDA and constant currency revenue growth as supplemental metrics. Adjusted EBITDA is defined by the company as earnings before interest income or expense, taxes, depreciation and amortization, stock-based compensation, and certain non-recurring or one-time items not reflective of ongoing core business operations, such as impairment charges. Constant currency calculations are described as showing current period revenues as if foreign exchange rates were the same as in the comparable prior-year period.

The company states that these non-GAAP measures are intended to provide an additional way of viewing aspects of its operations and to help management and investors evaluate performance and financial trends alongside GAAP results.
