Use of Non-GAAP Financial Measures

To supplement Pulmonx's condensed consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, Pulmonx provides certain non-GAAP financial measures in this release as supplemental financial metrics. Non-GAAP financial measures reflect an additional way of viewing aspects of the Company's operations that, when viewed with GAAP results, may provide a more complete understanding of factors and trends affecting Pulmonx's business.

Constant currency calculations show reported current period revenues as if the foreign exchange rates remain the same as those in effect in the comparable prior year period. Pulmonx uses results on a constant currency basis as one measure to evaluate its performance. Pulmonx calculates constant currency by calculating current-year results using foreign currency exchange rates from the applicable comparable period in the prior year. Pulmonx generally refers to such amounts calculated on a constant currency basis as excluding the impact of foreign exchange or being on a constant currency basis. Pulmonx believes the presentation of results on a constant currency basis in addition to reported results helps improve investors' ability to understand its operating results and evaluate its performance in comparison to prior periods. Pulmonx generally uses constant currency to facilitate management's financial and operational decision-making, including evaluation of Pulmonx's historical operating results.

The Company defines Adjusted EBITDA as earnings before interest income or expense, taxes, depreciation and amortization and stock-based compensation and may also exclude certain non-recurring, irregular or one-time items not reflective of our ongoing core business operations. Management believes in order to properly understand short-term and long-term financial trends, investors may wish to consider the impact of these excluded items in addition to GAAP measures. Further, management uses adjusted EBITDA for strategic and annual operating planning. We believe these non-GAAP financial measures are useful as a supplement in evaluating our ongoing operational performance and enhancing an overall understanding of our past financial performance.

Reconciliation of non-GAAP financial measures to the most comparable GAAP measures for the fourth quarter and full year ended December 31, 2025 and 2024 is set forth in the tables below.

The non-GAAP financial measures used by Pulmonx should be considered supplemental to, and not a substitute for, financial information prepared in accordance with GAAP. Because non-GAAP financial measures exclude the effect of items that increase or decrease the Company's reported results of operations, management strongly encourages investors to review, when they become available, the Company's consolidated financial statements and publicly filed reports in their entirety. The Company's definition of non-GAAP measures may differ from similarly titled measures used by others.
