Is Puma Biotechnology (PBYI) stock Halal?

Puma Biotechnology is a biopharmaceutical company dedicated to the development and commercialization of innovative therapies aimed at treating cancer. Its primary focus centers on enhancing cancer treatment through advanced pharmaceutical interventions, particularly targeting breast cancer and other tumors that overexpress the HER2 protein. A key product in Puma Biotechnology's portfolio is neratinib, an oral medication designed to inhibit cancer cell proliferation by interfering with the HER2/neu and EGFR kinases. For Muslim investors, though, the most pressing question is simpler: is Puma Biotechnology a Halal investment?

Is Puma Biotechnology Shariah compliant?

Yes. In the October 2026 screening Puma Biotechnology (PBYI) passes AAOIFI Shariah Standard No. 21: the business activity screen and every financial ratio screen hold. Technology companies rarely fail AAOIFI screening on what they sell. Software, hardware and digital services are permissible business activities, so for a company like Puma Biotechnology the Shariah question moves to the balance sheet: how much of its market value sits in interest bearing debt, how much of its cash earns Riba in conventional deposits, and whether incidental income from impermissible sources creeps past 5% of revenue. These are exactly the ratios AAOIFI Shariah Standard No. 21 polices, and they move every month with the share price.

Does Puma Biotechnology pass the business activity test?

Yes. In the October 2026 screening Puma Biotechnology holds an overall PASS, which a stock only earns when its core business clears the activity screen. The watch item for technology names is incidental: cash returns and platform content can carry impermissible elements, which AAOIFI tolerates only below the thresholds.

Is Puma Biotechnology's income Halal?

Yes, within AAOIFI's tolerance. Puma Biotechnology'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 98.55% tells holders of PBYI 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 Puma Biotechnology 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 $513M (market data as of 1 October 2026). Because the caps move with the share price, our Shariah Supervisory Board has PBYI re-screened every month, and the result above always shows the latest verdict.

Why do other halal screeners show a different verdict for Puma Biotechnology?

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.
