SINTX Technologies is a prominent player in the advanced ceramics industry, mainly focused on developing, manufacturing, and commercializing its proprietary silicon nitride ceramics. The company applies its expertise in this material for biomedical, industrial, and antipathogenic applications. Notably, silicon nitride is renowned for its strength, durability, and resistance to microbial growth, making it ideal for surgical implants and medical devices. For Muslim investors, though, the most pressing question is simpler: is SINTX Technologies a Halal investment?
Is SINTX Technologies Shariah compliant?
No. In the October 2026 screening SINTX Technologies (SINT) does not pass AAOIFI screening: it fails the interest-bearing investments screen. Medicines and medical devices are permissible, and healthcare companies like SINTX Technologies 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 SINTX Technologies pass the business activity test?
The activity screen is only part of the picture this month: SINTX Technologies currently fails the interest-bearing investments screen, 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 SINTX Technologies' income Halal?
Yes, within AAOIFI's tolerance. SINTX Technologies' income from non-permissible sources stays below 5% of revenue in the October 2026 screening.
Does SINTX Technologies meet AAOIFI's debt and investment ratio requirements?
Not in full. Interest bearing investments currently exceed the 30% cap, measured against a market capitalisation of $14.9M (market data as of 1 October 2026), while the other ratio stays within it. One breach is enough to fail the screening; the ratios are reassessed monthly under our Shariah Supervisory Board.
Why do other halal screeners show a different verdict for SINTX Technologies?
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.
