Glaukos is a medical technology company dedicated to the development and commercialization of innovative products for the treatment of glaucoma, corneal disorders, and retinal diseases. Its primary function is to address the substantial unmet medical needs present in ophthalmic healthcare. Glaukos is particularly recognized for pioneering novel micro-invasive glaucoma surgery (MIGS) devices, which are designed to reduce intraocular pressure in glaucoma patients through minimally invasive techniques. For Muslim investors, though, the most pressing question is simpler: is Glaukos a Halal investment?
Is Glaukos Shariah compliant?
Yes. In the October 2026 screening Glaukos (GKOS) passes AAOIFI Shariah Standard No. 21: the business activity screen and every financial ratio screen hold. Medicines and medical devices are permissible, and healthcare companies like Glaukos 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 Glaukos pass the business activity test?
Yes. In the October 2026 screening Glaukos holds an overall PASS, which a stock only earns when its core business clears the activity screen. Treating illness is permissible work; the scrutiny belongs to the financing behind it.
Is Glaukos' income Halal?
Yes, within AAOIFI's tolerance. Glaukos' income from non-permissible sources stays below 5% of revenue in the October 2026 screening, and the small impure portion is handled through purification: the factor of 98.79% tells holders of GKOS what share of each dividend to keep and what remainder to donate to charity. On a dividend yield of around None, the purification amount is modest but real.
Does Glaukos meet AAOIFI's debt and investment ratio requirements?
Yes. Both caps hold this month: interest bearing investments and interest bearing debt each stay below 30% of market capitalisation, measured against a market capitalisation of $9.68B (market data as of 1 October 2026). Because the caps move with the share price, our Shariah Supervisory Board has GKOS re-screened every month, and the result above always shows the latest verdict.
Why do other halal screeners show a different verdict for Glaukos?
Screeners can disagree without either being wrong. AAOIFI Shariah Standard No. 21, which Tabadulat applies, measures interest bearing debt and investments against market capitalisation with a 30% ceiling. MSCI and FTSE measure them against total assets with a 33% ceiling, and S&P and Dow Jones Islamic use a multi year average of market capitalisation. Data dates differ too, because each provider reads filings and prices on its own schedule. The same company can therefore pass one standard and fail another in the same month. Tabadulat publishes one answer, the AAOIFI result as of October 2026, and re-screens it every month.
