DOUBTFUL — SCREEN DOES NOT PASSstock

Is TNDM Halal?

Insulin-pump and diabetes-management devices are permissible healthcare products, but current debt/assets and liquidity/assets fail the examined asset-based screens.

What You Should Know

Tandem Diabetes Care, Inc. designs and sells insulin-delivery systems including t:slim X2 and Mobi pumps and related software. Its March 31, 2026 Form 10-Q reports $1,153.394 million of assets, $601.768 million of convertible debt, $179.325 million of cash, $390.931 million of short-term investments, $140.672 million of accounts receivable and $247.221 million of first-quarter revenue. Debt/assets is 52.17%, liquidity/assets is 49.44% and receivables-plus-cash/assets is 27.74%; gross interest income is not separately disclosed. The medical-device activity is generally permissible, but the current quantitative result is doubtful.

⚠️ Concerns

  • Debt/assets is 52.17%, above the examined 33.333% asset-based limit
  • Liquidity/assets is 49.44%, above the examined asset-based limit
  • Convertible debt and short-term investments are material
  • Gross interest income is unavailable; no purification amount is inferred
  • Re-screen after debt paydown, refinancing or a new filing

Overall
Fails

A licensed historical market-cap series is not stored; the asset-based screens fail on debt and liquidity.

Business-activity disclosure

Tandem designs and sells insulin pumps, diabetes-management systems and related software. Healthcare devices are generally permissible, while product, customer and end-use disclosure remains methodology-dependent.

Limitation: The filing does not allocate every product, customer or end use into a universal prohibited-activity numerator, and gross interest income is unavailable.

Purification

Gross interest income is unavailable and no purification amount is inferred from net investment-income amortization.

Inputs, assumptions and primary sources
  • Amounts are USD millions from Tandem Diabetes Care's March 31, 2026 Form 10-Q.
  • Debt is $601.768 million of noncurrent convertible debt; operating leases are excluded.
  • Cash and cash equivalents are $179.325 million. Short-term available-for-sale investments are $390.931 million and are included as identifiable interest-bearing securities.
  • Accounts receivable, net is $140.672 million and first-quarter revenue is $247.221 million.
  • Gross interest income is not separately disclosed; net investment-income amortization is not substituted, and the filing does not provide a universal prohibited-revenue numerator.

This is a reproducible financial screen, not a fatwa. A failed total-assets screen can coexist with a pass under a market-cap methodology. ZakatInvest keeps the qualitative assessment separate so numerical thresholds do not erase material context.
