--- title: "Is Merck Stock Halal?" canonical: https://www.halalwallet.ca/is-it-halal/merck-stock publisher: HalalWallet license: CC BY 4.0 verdict: halal verdict_label: Halal entity_type: stock ticker: MRK exchange: NYSE last_reviewed: 2026-06-15 data_as_of: 2026-03-31 standards_disagree: true authorities_with_position: 3 authority_agreement: unanimous --- # Is Merck Stock Halal? **Authority consensus:** All 3 halal screening authorities with a published position rate Merck & Co., Inc. halal. **Verdict: Halal** (Generally permissible) Merck & Co., Inc. (MRK) passes our AAOIFI-based screen. Its core business is permissible, and (data as of 2026-03-31) interest-bearing debt is 16.7% of market cap and cash plus interest-bearing securities 1.9% — both inside the 30% AAOIFI thresholds. Ratios move with the share price, so check the data-as-of date; any incidental interest income should be purified. > HalalWallet is not a Shariah authority and does not issue religious rulings. We compile the most complete public record of what Shariah scholars, screening authorities, and mainstream standards say — reproduced from primary sources with dates and citations — and let you decide. ## How we read the evidence Merck & Co. is one of the world's largest research-based pharmaceutical companies, anchored by its blockbuster cancer immunotherapy Keytruda along with vaccines and a sizeable animal-health business. Developing and selling prescription medicines and vaccines is a permissible healthcare activity, with no alcohol, gambling, tobacco, or conventional-finance exposure — so Zoya, Musaffa, and HalalScreener all classify MRK as halal. The financial ratios are solid: HalalScreener shows debt-to-market-cap at 15.7% and prohibited income at just 0.70% of revenue, both well inside AAOIFI limits, earning a B+ (79/100) compliance grade. A small amount of interest income means routine dividend purification applies, but it is minor. The practical takeaway: MRK passes both screens with a comfortable margin. Some investors apply an ethical-conscience filter to specific pharmaceutical product lines, but that is a personal preference beyond the standard Shariah screen, which MRK clears. Re-check the ratios after new filings and avoid leverage. ## Business activity screen Result: Pass Merck & Co. (known as MSD outside the U.S. and Canada) is a research-driven pharmaceutical company. Its largest products include the oncology drug Keytruda, vaccines, and animal-health products. Revenue is from developing, manufacturing, and selling prescription medicines and vaccines — a permissible healthcare activity. No alcohol, gambling, tobacco, or conventional-finance revenue is disclosed. HalalScreener reports non-compliant (prohibited) income at 0.70% of revenue and debt-to-market-cap at 15.7% — both well under AAOIFI thresholds. Modest dividend purification applies for the small interest-income share. ## Financial ratio screen (AAOIFI) Data as of: 2026-03-31 | Screen | Value | Limit | Result | |---|---|---|---| | Interest-bearing debt / market cap | 16.7% | < 30% | Pass | | Cash + interest-bearing securities / market cap | 1.9% | < 30% | Pass | | Impermissible income / total revenue | 0.5% | < 5% | Pass | Screening basis: AAOIFI Shariah Standard No. 21 — the most widely used and most conservative mainstream standard (interest-bearing debt and securities each < 30% of market cap; impermissible income < 5%). Other standards (Dow Jones Islamic, S&P Shariah, MSCI Islamic, FTSE Yasaar) use ~33% limits or screen against total assets.

The headline label follows AAOIFI (the strictest mainstream standard). | Standard | Debt | Cash & interest securities | Limit / basis | Result | |---|---|---|---|---| | AAOIFI (our standard) | 16.7% | 1.9% | < 30% of market cap | Pass | | Dow Jones Islamic / S&P Shariah threshold | 16.7% | 1.9% | < 33% of market cap | Pass | | MSCI Islamic / FTSE Yasaar basis | 38.2% | 4.4% | < 33.33% of total assets | Fail | HalalWallet computation reproducing each standard's threshold and denominator from public filings (balance sheet as of 2026-03-31) — not the providers' licensed index determinations, which can differ. Debt is interest-bearing borrowings (operating leases excluded); the < 5% impermissible-income screen is common to all and shown above. Dow Jones/S&P use a trailing 24–36-month average market cap; MSCI/FTSE add entry/exit buffers and a receivables screen. ## Scholars' and screeners' positions - **Zoya**: Classifies MRK as Shariah-compliant under its AAOIFI-based methodology.

([source](https://halalscreener.app/en/stock/MRK)) ## Purification Even Shariah-compliant companies typically earn a small amount of incidental interest on corporate cash. The standard practice is to purify: donate the proportion of your dividends (and, per some scholars, capital gains) attributable to impermissible income. Our purification calculator automates the math from your holding and the company's disclosed figures. ## Sources - MRK latest quarterly filing (balance sheet 2026-03-31) (https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&company=Merck%20%26%20Co.%2C%20Inc.&type=10-Q) - AAOIFI Shariah Standards (https://aaoifi.com) - Merck & Co. 10-K filings (SEC EDGAR) (https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=MRK&type=10-K) - Zoya — MRK Shariah compliance status (https://zoya.finance/stocks/mrk) - Musaffa — MRK Shariah status (HALAL) (https://musaffa.com/stock/MRK/) - HalalScreener — MRK (Halal, B+ 79/100) (https://halalscreener.app/en/stock/MRK) ## Frequently asked questions ### Is Merck & Co., Inc.
