Is Silicon Laboratories (SLAB) stock Halal?

Silicon Laboratories specializes in the design and development of semiconductors and software solutions. Primarily, it focuses on the Internet of Things (IoT) market, providing high-performance microcontrollers, wireless standards including Bluetooth and Wi-Fi, and sensors that enable connectivity and communication between devices. The company also offers timing devices and power isolation products, which are critical in ensuring the seamless operation of various electronic systems. For Muslim investors, though, the most pressing question is simpler: is Silicon Laboratories a Halal investment?

Is Silicon Laboratories Shariah compliant?

Yes. In the October 2026 screening Silicon Laboratories (SLAB) 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 Silicon Laboratories 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 Silicon Laboratories pass the business activity test?

Yes. In the October 2026 screening Silicon Laboratories 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 Silicon Laboratories' income Halal?

Yes, within AAOIFI's tolerance. Silicon Laboratories' 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 100% tells holders of SLAB 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 Silicon Laboratories 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 $7.39B (market data as of 1 October 2026). Because the caps move with the share price, our Shariah Supervisory Board has SLAB re-screened every month, and the result above always shows the latest verdict.

Why do other halal screeners show a different verdict for Silicon Laboratories?

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.
