Is PDF Solutions (PDFS) stock Halal?

PDF Solutions is a company specializing in software and engineering services that enhance the performance of semiconductor manufacturing processes. The company's key function is to provide analytics and quality control software for integrated circuit producers, striving to improve yield and efficiency in chip production. Pdf Solutions utilizes cutting-edge technology to offer data solutions that streamline manufacturing workflows and reduce production costs. Before any of that matters to a Muslim investor, one question comes first: is PDF Solutions stock Halal?

Is PDF Solutions Shariah compliant?

Yes. In the October 2026 screening PDF Solutions (PDFS) passes AAOIFI Shariah Standard No. 21: the business activity screen and every financial ratio screen hold. The Shariah case on a technology company like PDF Solutions is rarely about the product. What AAOIFI Shariah Standard No. 21 examines is the money around the product: cash parked in instruments that earn Riba, borrowing measured against a market capitalisation that moves daily, and any incidental income from sources Islam prohibits, which must stay below 5% of revenue.

Does PDF Solutions pass the business activity test?

Yes. In the October 2026 screening PDF Solutions 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 PDF Solutions' income Halal?

Yes, within AAOIFI's tolerance. PDF Solutions' 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 99.41% tells holders of PDFS 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 PDF Solutions 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 $2.16B (market data as of 1 October 2026). Because the caps move with the share price, our Shariah Supervisory Board has PDFS re-screened every month, and the result above always shows the latest verdict.

Why do other halal screeners show a different verdict for PDF Solutions?

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.
