Is Outset Medical (OM) stock Halal?

Outset Medical is a pioneering company in the medical technology field, primarily focusing on the development and commercialization of innovative dialysis solutions. Its flagship product, the Tablo Hemodialysis System, is designed to simplify dialysis treatments, whether in medical facilities or at home. The system integrates water purification with dialysate production, offering a seamless, all-in-one dialysis solution. This transformative approach aims to make dialysis more accessible and user-friendly for patients and healthcare providers. For Muslim investors, though, the most pressing question is simpler: is Outset Medical a Halal investment?

Is Outset Medical Shariah compliant?

No. In the October 2026 screening Outset Medical (OM) does not pass AAOIFI screening: it fails the interest-bearing investments and interest-bearing debt screens. Medicines and medical devices are permissible, and healthcare companies like Outset Medical 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 Outset Medical pass the business activity test?

The activity screen is only part of the picture this month: Outset Medical 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 Outset Medical's income Halal?

Yes, within AAOIFI's tolerance. Outset Medical's income from non-permissible sources stays below 5% of revenue in the October 2026 screening.

Does Outset Medical meet AAOIFI's debt and investment ratio requirements?

No. Both ratios currently breach the 30% caps, measured against a market capitalisation of $56.4M (market data as of 1 October 2026): 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 OM re-screened every month.

Why do other halal screeners show a different verdict for Outset Medical?

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.
