Expected 2026 Cash Usage $23 million Approximate expected decrease in cash, cash equivalents and marketable securities during 2026
constant currency financial
"a decrease of 6% on a constant currency basis"
Constant currency is a way of measuring financial results that removes the effects of changes in currency exchange rates. It allows for a clearer comparison of a company's performance over time by showing what the numbers would look like if exchange rates had stayed the same. This helps investors understand whether growth comes from actual business improvements or just currency fluctuations.
Adjusted EBITDA financial
"Adjusted EBITDA loss in the second quarter of 2026 was $5.1 million"
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
non-GAAP financial measures financial
"Pulmonx provides certain non-GAAP financial measures in this release"
Non-GAAP financial measures are numbers companies use to show their financial performance that exclude certain expenses or income. They help investors see how the company might perform without one-time costs or other unusual items, giving a different perspective from official reports. However, since they can be adjusted, they don’t always tell the full story and should be looked at alongside standard financial figures.
Premarket Approval medical
"received U.S. Food and Drug Administration (FDA) Premarket Approval (PMA)"
Premarket approval is the formal regulatory clearance required before certain medical devices can be sold, based on detailed evidence that the product is safe and effective. For investors, it’s a major milestone because receiving approval typically clears the way for commercial sales and reduces regulatory uncertainty, while failure or delays can block revenue and raise the risk profile; think of it like a safety certificate needed before a new car model can be sold.
breakthrough device medical
"following its designation as a “breakthrough device.”"
'Breakthrough device' is a regulatory designation for a medical device judged to offer a substantial improvement in diagnosing or treating a serious or life‑threatening condition, granting it priority review and more intensive interaction with regulators to accelerate approval. For investors, it matters because the label can shorten time to market and reduce regulatory uncertainty—like putting a product into the fast lane—potentially raising commercial value and lowering development risk.
deferred revenue financial
"Deferred revenue | 16"
Cash a company has already received for goods or services it has promised but not yet delivered; it's recorded as a liability because the company still owes that product, service, or future revenue recognition. For investors, deferred revenue signals upcoming work or deliveries that will convert into reported sales over time and affects short-term obligations, cash flow quality, and how quickly a firm can grow recognized revenue—think of it like prepaid subscriptions or gift cards a business must honor later.
Worldwide revenue $22.8 million 5% decrease year over year
U.S. revenue $14.2 million 4% decrease year over year
International revenue $8.6 million 6% decrease year over year; 9% decrease on a constant currency basis
International revenue excluding China $8.6 million 12% increase year over year; 9% increase on a constant currency basis
Gross margin 78% Up from 72% in the prior-year quarter
Net loss $10.1 million 34% reduction versus prior-year quarter net loss of $15.2 million
Adjusted EBITDA loss $5.1 million 39% reduction versus $8.4 million loss in the prior-year quarter
Guidance

Expects full-year 2026 revenue of $90 million to $92 million, gross margin of approximately 76%, total operating expenses of $109 million to $111 million including about $15 million of stock-based compensation, and an approximately $23 million decrease in cash, cash equivalents and marketable securities.

Webcast and Conference Call Details
Pulmonx will host a conference call today, July 29, 2026, at 1:30 p.m. PT / 4:30 p.m. ET to discuss its second quarter financial results. A live webcast of the conference call will be available on the Investor Relations section of the Company’s website at https://investors.pulmonx.com/. 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, 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.

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 our 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. These forward-looking statements include, but are not limited to, statements regarding our ability to drive improvements in revenue growth, execute against our strategic priorities, and deliver meaningful operating leverage, our possible or assumed future results of operations, including long-term outlook, descriptions of our revenues, total operating expenses, gross margin, balances of cash, cash equivalents, and marketable securities, profitability, guidance for full year 2026, and overall business strategy. 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 4, 2026, available at www.sec.gov. 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. Except to the extent required by law, we undertake no obligation to update or review any estimate, projection, or forward-looking statement.
