RVTY

What You Should Know

Revvity, Inc. — the company formed from the former PerkinElmer's life-sciences and diagnostics businesses — provides reagents, instruments, software, and diagnostics used in research, drug discovery, and clinical testing, including newborn screening and immunodiagnostics. Supplying tools and diagnostics that advance science and healthcare is a permissible activity, so the business-activity screen passes. The verdict depends on the balance sheet: Revvity has grown through acquisitions and carries interest-bearing debt, so confirm the total-debt-to-market-cap ratio against the 33% threshold and the receivables ratio against the board's threshold using the latest filings — the deciding screens. Interest income on cash should be checked against the 5% threshold and the corresponding portion of returns purified. Assuming the ratios hold, RVTY is generally screened as halal, with routine purification of minor interest income.
