“Our record quarterly results reflect the continued traction of our commercial strategy, particularly in the United States where we continue to expand our presence by opening new accounts, preparing to launch new pilot programs to optimize patient workflows, and building local awareness of our Zephyr Valves,” said Steve Williamson, President, and Chief Executive Officer. “Our strategy is demonstrating positive momentum, giving us confidence in our ability to deliver our projected growth through the balance of the year and beyond.”

Second Quarter 2024 Financial ResultsTotal worldwide revenue in the second quarter of 2024 was $20.8 million, a 21% increase from $17.2 million in the second quarter of 2023. U.S. revenue was $13.9 million, a 26% increase from the second quarter of 2023. International revenue was $6.9 million, a 12% increase compared to the second quarter of 2023. The growth in revenue reflects continued commercial momentum and adoption of Zephyr Valve procedures.

Gross profit in the second quarter of 2024 was $15.3 million, compared to $12.7 million for the second quarter of 2023. Gross margin for the second quarter of 2024 was 74%, compared to 74% for the same period in 2023.

Operating expenses in the second quarter of 2024 were $30.9 million, compared to $29.2 million for the second quarter of 2023, representing an increase of 6%. The increase in operating expenses was primarily attributable to a one-time, non-cash charge of $1.7 million to impair internally developed software following a strategic decision to adopt a more efficient solution.

Net loss in the second quarter of 2024 was $15.3 million, or $0.39 per share, compared to a net loss of $16.2 million, or $0.43 per share, for the same period in 2023.

Adjusted EBITDA loss in the second quarter of 2024 was $7.6 million compared to $10.3 million for the same period in 2023.

Cash, cash equivalents, and marketable securities totaled $114.5 million as of June 30, 2024.

2024 Financial OutlookPulmonx continues to expect revenue for the full year 2024 to be in the range of $81 million to $84 million.

The Company continues to expect gross margin for the full year 2024 to fall within the range of 74% to 75%.

Pulmonx continues to expect total operating expenses for the full year 2024 to fall within the range of $127 million to $129 million, inclusive of approximately $25 million of non-cash stock-based compensation.

Use of Non-GAAP Financial MeasuresTo 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, such as impairment charges. 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 these non-GAAP financial measures to the most comparable GAAP measures 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.
