Is Pacific Biosciences of California (PACB) stock Halal?

Pacific Biosciences of California is a biotechnology company that specializes in developing and commercializing innovative sequencing systems to assist in scientific research and genetic analysis. Its flagship technology, the Single Molecule, Real-Time (SMRT) sequencing platform, enables detailed and accurate exploration of genetic structures, making it invaluable to researchers in genomics, epigenetics, and personalized medicine. For Muslim investors, though, the most pressing question is simpler: is Pacific Biosciences of California a Halal investment?

Is Pacific Biosciences of California Shariah compliant?

No. In the October 2026 screening Pacific Biosciences of California (PACB) 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 Pacific Biosciences of California 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 Pacific Biosciences of California pass the business activity test?

The activity screen is only part of the picture this month: Pacific Biosciences of California 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 Pacific Biosciences of California's income Halal?

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

Does Pacific Biosciences of California meet AAOIFI's debt and investment ratio requirements?

No. Both ratios currently breach the 30% caps, measured against a market capitalisation of $737M (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 PACB re-screened every month.

Why do other halal screeners show a different verdict for Pacific Biosciences of California?

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.
