Is Pulmonx (LUNG) stock Halal?
Under AAOIFI Shariah Standard No. 21, a Halal stock keeps non-permissible income below 5% of revenue and interest-bearing debt and investments each below 30% of market capitalisation. Pulmonx Corp. (LUNG) does not meet the threshold for the interest-bearing investments and interest-bearing debt screens as of September 2026, so it is not Shariah compliant.
Pulmonx is a leading medical technology company specializing in minimally invasive treatments for chronic obstructive pulmonary disease (COPD). The company focuses on developing and commercializing advanced technologies that offer new options for patients suffering from lung disorders. One of its flagship products, the Zephyr Valve, is a tiny device designed for bronchoscopic lung volume reduction in severe emphysema patients, providing an alternative to invasive surgical procedures. For Muslim investors, though, the most pressing question is simpler: is Pulmonx a Halal investment?
Is Pulmonx Shariah compliant?
Medicines and medical devices are permissible, and healthcare companies like Pulmonx usually clear the activity screen comfortably. What AAOIFI Shariah Standard No. 21 watches is the financing behind the pipeline: drug development is expensive, and the 30% interest bearing debt cap decides the verdict more often than the science does.
Does Pulmonx pass the business activity test?
The activity screen is only part of the picture this month: Pulmonx currently fails the interest-bearing investments and interest-bearing debt screens, so the overall verdict is not compliant regardless of the business itself. Treating illness is permissible work; the scrutiny belongs to the financing behind it.
Is Pulmonx's income Halal?
Yes, within AAOIFI's tolerance. Pulmonx's income from non-permissible sources stays below 5% of revenue in the September 2026 screening.
Does Pulmonx meet AAOIFI's debt and investment ratio requirements?
No. Both ratios currently breach the 30% caps: interest bearing investments and interest bearing debt each exceed the limit AAOIFI permits for a Halal investment. The ratios move with the share price as well as the balance sheet, and our Shariah Supervisory Board has LUNG re-screened every month.
