Is Twist Bioscience (TWST) stock Halal?

Twist Bioscience is a pioneering biotechnology firm revolutionizing the field of synthetic DNA. The company's primary function is to produce synthetic DNA using a proprietary silicon-based manufacturing platform, enabling the creation of high-quality, accurate, and cost-effective DNA at scale. Twist Bioscience's innovations impact multiple sectors, including pharmaceuticals, industrial chemicals, agriculture, and data storage, offering transformative solutions in drug development, crop protection, and genomic research. For Muslim investors, though, the most pressing question is simpler: is Twist Bioscience a Halal investment?

Is Twist Bioscience Shariah compliant?

Yes. In the October 2026 screening Twist Bioscience (TWST) 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 Twist Bioscience 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 Twist Bioscience pass the business activity test?

Yes. In the October 2026 screening Twist Bioscience 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 Twist Bioscience's income Halal?

Yes, within AAOIFI's tolerance. Twist Bioscience's 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 98.75% tells holders of TWST 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 Twist Bioscience 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 $12.8B (market data as of 1 October 2026). Because the caps move with the share price, our Shariah Supervisory Board has TWST re-screened every month, and the result above always shows the latest verdict.

Why do other halal screeners show a different verdict for Twist Bioscience?

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.

Tabadulat is an ADGM regulated brokerage whose license covers Shari'a Compliant Regulated Activities, as the FSRA permission names them. New to the terminology? Gharar and Maysir, Sukuk, Zakat and purification are all explained in plain English.
