Sentiment and the balance of points

Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

Cash and cash equivalents were $52.690 million as of September 30, 2026.

For full-year 2026, Pulmonx expects revenue of $90 million to $92 million, gross margin of approximately 77%, and operating expenses of $108 million to $109 million, including approximately $14 million of non-cash stock-based compensation. It expects cash, cash equivalents and marketable securities to decrease approximately $22 million, assuming no additional drawdowns under its credit facility.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

constant currency financial
"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 was $3.5 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-cash stock-based compensation financial
"approximately $14 million of non-cash stock-based compensation"
Non-cash stock-based compensation is pay given to employees or directors in the form of company shares or rights to buy shares instead of cash; it shows up on financial statements as an accounting charge even though no cash leaves the company. It matters to investors because it can lower reported profits and increase the number of shares outstanding—like paying with coupons instead of cash—affecting earnings per share and ownership dilution even though the company keeps its cash.
credit facility financial
"no additional drawdowns under the Company’s credit facility"
A credit facility is a flexible loan arrangement that allows a borrower to access funds up to a set limit whenever needed, similar to a company having an overdraft option on a bank account. It matters to investors because it indicates how easily a business can secure cash when required, affecting its ability to manage expenses, invest, or respond to financial challenges.

Webcast and Conference Call Details
Pulmonx will host a conference call today, October 27, 2026, at 1:30 p.m. PT / 4:30 p.m. ET to discuss its third quarter financial results.

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 that, 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.

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 August 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.
