Pulmonx's overall stock score reflects a mix of strong revenue growth and product innovation, but significant challenges in profitability and valuation. While international expansion and the resolution of legal concerns are promising, the company's financial struggles and valuation issues weigh heavily on the score.

Positive Factors

Financial Performance

Product Launch

LungTrax platform is in full launch, with some hospitals already seeing increased throughput and reduced time-to-procedure.

Negative Factors

Market Penetration

The main bear case includes greater than anticipated tariff impact and lack of growth reacceleration, with the exact formula to penetrate the end market still being explored.

Tariff Impact

Tariffs could impact the business through component sourcing cost inflation and other countries' reciprocal tariffs, potentially harming gross margins.

Pulmonx Business Overview & Revenue Model

Company Description

Pulmonx Corporation, a medical technology company, provides minimally invasive devices for the treatment of chronic obstructive pulmonary diseases. It offers Zephyr Endobronchial Valve, a solution for the treatment of bronchoscopic in adult patients with hyperinflation associated with severe emphysema; and Chartis Pulmonary Assessment System, a balloon catheter and console system with flow and pressure sensors that are used to assess the presence of collateral ventilation. The company also provides StratX Lung Analysis Platform, a cloud-based quantitative computed tomography analysis service that offers information on emphysema destruction, fissure completeness, and lobar volume to help identify target lobes for the treatment with Zephyr Valves. It serves emphysema patients in the United States, Europe, the Middle East, Africa, the Asia-Pacific, and internationally. The company was formerly known as Pulmonx and changed its name to Pulmonx Corporation in December 2013. Pulmonx Corporation was incorporated in 1995 and is headquartered in Redwood City, California.

How the Company Makes Money

Pulmonx generates revenue through the sale of its medical devices, particularly the Zephyr Endobronchial Valve, to hospitals and healthcare providers. The company earns money by marketing and distributing these devices in various geographical markets, including the United States, Europe, and Asia. Revenue is also supported by Pulmonx's efforts in training healthcare professionals to effectively use their products, thus enhancing the adoption rate of their technologies. Furthermore, strategic partnerships with medical institutions and ongoing clinical trials help to validate and promote the efficacy of the company's products, which in turn drives sales and revenue growth.
