Exhibit 99.1
Pulmonx Reports Second Quarter 2022 Financial Results

Redwood City, CA – August 2, 2022 – Pulmonx Corporation (Nasdaq: LUNG) (“Pulmonx” or the "Company"), a global leader in minimally invasive treatments for lung disease, today reported financial results for the second quarter ended June 30, 2022.

Recent Highlights
Achieved a new high in worldwide revenue of $14.0 million in the second quarter of 2022, a 14% increase over the same period last year and an increase of 19% on a constant currency basis
Realized gross margin of 75% in the second quarter of 2022 as compared to 74% in the same period last year
Added 18 new U.S. treatment centers for Zephyr Valves in the second quarter 2022, increasing total U.S. treatment centers to 248
Study published in the American Journal of Respiratory and Critical Care Medicine showing that a reduction in hyperinflation using Zephyr Valves was shown to improve cardiac function in severe COPD/emphysema patients
“We are pleased with our performance, which reflects our strongest quarter of U.S. sales to date, driven by procedure volumes, new account openings, and our patient engagement initiatives,” said Glen French, President & Chief Executive Officer. “We remain confident in our full year outlook and continue to prudently manage our business to ensure long-term growth and success.”

Second Quarter 2022 Financial Results
Total worldwide revenue in the second quarter of 2022 was $14.0 million, a 14% increase from $12.2 million in the second quarter of 2021 and an increase of 19% on a constant currency basis. U.S. revenue was $8.6 million, a 31% increase from the second quarter of 2021. International revenue was $5.3 million, a 5% decrease compared to the second quarter of 2021, and a 4% increase on a constant currency basis. The increase in U.S. revenue reflects continued commercial momentum and growth of Zephyr Valve procedure volumes, while the change in international revenue reflects negative impact from foreign currency exchange rates.

Gross profit in the second quarter of 2022 was $10.4 million, a 15% increase compared to $9.0 million for the second quarter of 2021. Gross margin for the second quarter of 2022 was 75%, up from 74% for the same period in 2021. The improvement in gross margin reflects benefits from production efficiencies.

Operating expenses in the second quarter of 2022 were $24.8 million, compared to $21.7 million for the second quarter of 2021, representing an increase of 14%. The increase in operating expenses was driven primarily by an increase in spending on commercial infrastructure and activity, and an increase in non-cash stock-based compensation.

Net loss in the second quarter of 2022 was $14.6 million, or $0.40 per share, compared to a net loss of $13.0 million, or $0.36 per share, for the same period in 2021.

Cash, cash equivalents, and marketable securities totaled $166.8 million as of June 30, 2022.

2022 Financial Outlook
Pulmonx continues to expect revenue for the full year 2022 to be in the range of $55 million to $60 million.

The Company also continues to expect total operating expenses for the full year 2022 to fall within the range of $100 million to $105 million inclusive of stock-based compensation.

Use of Non-GAAP Financial Measures
Pulmonx has presented constant currency percentage change in revenues, a non-GAAP financial measure, in this press release. 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. Reconciliation of this non-GAAP financial measure to the most comparable GAAP measure is set forth in the tables below.

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. 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.

This non-GAAP financial measure 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.

Forward-Looking Statements
This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements are based on management’s current assumptions and expectations of future events and trends, which affect or may affect the Company’s business, strategy, operations or financial performance, and actual results may differ materially from those expressed or implied in such statements due to numerous risks and uncertainties.

Forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified. Factors that could cause actual results to differ materially from those contemplated in this press release can be found in the Risk Factors section of Pulmonx’s public filings with the Securities and Exchange Commission (“SEC”), including the Quarterly Report on Form 10-Q filed with the SEC on May 9, 2022, available at Because forward-looking statements are inherently subject to risks and uncertainties, you should not rely on these forward-looking statements as predictions of future events. All statements other than statements of historical fact are forward-looking statements.
