May 2, 2023

REDWOOD CITY, Calif., May 02, 2023 (GLOBE NEWSWIRE) -- Pulmonx Corporation (Nasdaq: LUNG) (“Pulmonx” or the "Company"), a global leader in minimally invasive treatments for lung disease, today reported financial results for the first quarter of 2023 ended March 31, 2023.

Recent Highlights

  • Recorded worldwide revenue of $14.5 million in the first quarter of 2023, a 35% increase over the same period last year and an increase of 37% on a constant currency basis
  • Delivered $9.3 million in U.S. revenue in the first quarter of 2023, representing 55% year-over-year growth
  • Realized gross margin of 73% in the first quarter of 2023
  • Added 15 new U.S. treatment centers for Zephyr Valves in the first quarter 2023

“We are pleased with our first quarter performance. As expected, we saw sustained momentum in a more normalized environment, particularly in the U.S.,” said Glen French, President and Chief Executive Officer. “Our experiences over the last two quarters have validated our commercial focus and we are delighted to see strong early traction and receptivity across our account base. We remain confident in our ability to deliver on our year-end goals as we advance our efforts to address the vast unmet need of patients with severe emphysema.”

First Quarter 2023 Financial Results
Total worldwide revenue in the first quarter of 2023 was $14.5 million, a 35% increase from $10.8 million in the first quarter of 2022 and an increase of 37% on a constant currency basis. U.S. revenue was $9.3 million, a 55% increase from the first quarter of 2022. International revenue was $5.2 million, a 9% increase compared to the first quarter of 2022, and a 15% increase on a constant currency basis. The growth in revenue reflects continued commercial momentum and adoption of Zephyr Valve procedures as we are now operating in a more stabilized environment.

Gross profit in the first quarter of 2023 was $10.6 million, compared to $8.1 million for the first quarter of 2022. Gross margin for the first quarter of 2023 was 73%, compared to 75% for the same period in 2022, reflecting slightly lowered capacity utilization.

Operating expenses in the first quarter of 2023 were $27.0 million, compared to $23.8 million for the first quarter of 2022, representing an increase of 13%. The increase in operating expenses was primarily attributable to an increase in clinical and development investments related to our AeriSeal program, an increase in sales and marketing costs, and an increase in legal and stock-based compensation expenses.  

Net loss in the first quarter of 2023 was $15.9 million, or $0.42 per share, compared to a net loss of $15.8 million, or $0.43 per share, for the same period in 2022.

Adjusted EBITDA loss in the first quarter of 2023 was $11.2 million compared to $11.8 million for the same period in 2022.

Cash, cash equivalents, and marketable securities totaled $155.5 million as of March 31, 2023 and include the $20 million drawdown on our existing term loan which occurred in February of 2023.

2023 Financial Outlook
Pulmonx continues to expect revenue for the full year 2023 to be in the range of $63 million to $65 million.

The Company also continues to expect gross margin for the full year 2023 to fall within the range of 73% to 74%.

Pulmonx continues to expect total operating expenses for the full year 2023 to fall within the range of $112 million to $114 million, inclusive of approximately $22 million of non-cash stock-based compensation.

Webcast and Conference Call Details
Pulmonx will host a conference call today, May 2, 2023, at 1:30 p.m. PT / 4:30 p.m. ET to discuss its first quarter financial results. A live webcast of the conference call will be available on the Investor Relations section of the Company's website at The webcast will be archived on the website following the completion of the call.

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 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.
