**Pulmonx Reports First Quarter 2026 Financial Results**

**Redwood City, CA – April 29, 2026** – 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 2026 ended March 31, 2026.

**Recent Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Achieved worldwide revenue of $20.6 million in the first quarter of 2026, a 9% decrease over the same period last year and a decrease of 12% on a constant currency basis

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Delivered $13.3 million in U.S. revenue in the first quarter of 2025, representing a 7% year-over-year decrease

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Delivered $7.3 million in international revenue in the first quarter of 2026, representing a 12% year-over-year decrease and a decrease of 21% on a constant currency basis; excluding China, year-over-year international revenue increased 22% and 9% on a constant currency basis

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Realized gross margin of 78% in the first quarter of 2026

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• As previously reported, refinanced prior debt under a new 5-year interest-only credit facility that extends maturity out to 2031

"During the first quarter we initiated our refreshed U.S. commercial strategies and continued to execute in our direct international markets. We are encouraged by early signs of progress from the actions we have taken to refocus our U.S. sales organization and advance our clinical programs," said Glen French, President and Chief Executive Officer of Pulmonx. "With a fully staffed global sales organization, we remain confident in our ability to drive sequential improvement in revenue growth, execute against our strategic priorities, and deliver meaningful operating leverage in 2026."

**First Quarter 2026 Financial Results**

Total worldwide revenue in the first quarter of 2026 was $20.6 million, a 9% decrease from $22.5 million in the first quarter of 2025 and a decrease of 12% on a constant currency basis. U.S. revenue was $13.3 million, a 7% decrease from the first quarter of 2025. International revenue was $7.3 million, a 12% decrease compared to the first quarter of 2025, and a 21% decrease on a constant currency basis. The decrease in international revenue was attributable to a lack of sales into China as we await the renewal of our registration certificate. Excluding China, international revenue grew 22% and 9% on a constant currency basis.

Gross profit in the first quarter of 2026 was $16.0 million, compared to $16.3 million for the first quarter of 2025. Gross margin for the first quarter of 2026 was 78%, compared to 73% for the same period in 2025.

Operating expenses in the first quarter of 2026 were $29.0 million, compared to $30.9 million for the first quarter of 2025, representing a decrease of 6%.

Net loss in the first quarter of 2026 was $13.7 million, or $0.33 per share, compared to a net loss of $14.4 million, or $0.36 per share, for the same period in 2025.

Adjusted EBITDA loss in the first quarter of 2026 was $8.5 million.

Cash and cash equivalents totaled $61.6 million as of March 31, 2026.

**2026 Financial Outlook**

Pulmonx continues to expect revenue for the full year 2026 to be in the range of $90 million to $92 million.

------

The Company continues to expect gross margin for the full year 2026 to be approximately 75%.

Pulmonx continues to expect total operating expenses for the full year 2026 to fall within the range of $113 million to $115 million, inclusive of approximately $19 million of non-cash stock-based compensation.

The Company continues to expect cash, cash equivalents, and marketable securities to decrease by approximately $23 million for the full year 2026 assuming no additional drawdowns under the Company's credit facility.

**Webcast and Conference Call Details**

Pulmonx will host a conference call today, April 29, 2026, 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 <u>https://investors.pulmonx.com/</u>. 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.
