Is Celestica / CLS Halal?

Celestica Inc. (TSX: CLS; also NYSE-listed) is a Toronto-headquartered electronics manufacturing services company — design, engineering and manufacture of complex electronics and data-center infrastructure, plus hardware platform solutions for hyperscalers and cloud providers. But its ATS segment includes a verified Aerospace and Defense business — a FAIL at gate one, re-checked every quarter.

The two-gate Shariah screen

Every screener on this site runs the same two gates: first, the business must be halal (no conventional insurance, banking, alcohol, gambling, weapons manufacturing, and the like); second, the financial ratios must clear (debt under roughly 33% of market cap, non-compliant income under roughly 5%).

Gate one: the business — FAIL

Celestica designs, engineers, manufactures and supplies complex electronics and data-center infrastructure, plus hardware platform solutions (HPS) — its own AI compute/networking hardware platforms sold as-is or customized. It reports two segments: CCS — Connectivity & Cloud Solutions (Communications and Enterprise end markets; hyperscalers, cloud providers, data-center OEMs) and ATS — Advanced Technology Solutions, which the company states comprises Aerospace and Defense (A&D), Industrial, HealthTech and Capital Equipment businesses. The Q2 2026 MD&A notes sequential ATS revenue growth was "primarily driven by increased demand in our Industrial, Capital Equipment and A&D businesses." The A&D business is not disclosed separately — ATS overall was 19% of total revenue in Q2 2026 (US$888.3 million of US$4,698.6 million) — but the defence exposure is verified in the company's own filings. Weapons and defence are excluded by the business screen. Gate one: FAIL.

Gate two: the ratios — both pass

The debt gate passes comfortably. As at June 30, 2026: borrowings under the credit facility US$740.0 million (Term A US$250.0 million + Term B US$490.0 million; US$1,750.0 million revolver undrawn) + finance lease obligations US$75.5 million = US$810.4 million (operating lease liabilities of US$170.8 million are separate; cash US$535.7 million). Market cap is roughly US$46.1 billion (US$365.44 NYSE close on September 25, 2026 × about 126.11 million shares outstanding — the August 7, 2026 equity offering of 11,129,031 shares at US$310 is included). That puts debt at ~1.8% of market cap — far under the ~33% ceiling (~2.1% including operating leases). The interest-income gate also passes: the Q2 2026 Form 10-Q reports standalone interest income of US$3.8 million against US$4,698.6 million of revenue — about 0.08%, far under the ~5% screen. Gate two: both gates pass — the FAIL rests entirely on gate one.

What other screeners say

ShariaPortfolio covers Celestica and states it is "Shariah Compliant" — passing 4 of 5 of its standards — while its own page describes the A&D business. This site applies its own business screen: weapons and defence exposure fails at gate one regardless of third-party ratings, so the FAIL here is independent of ShariaPortfolio's assessment. No Zoya or Musaffa rating for CLS could be verified as of September 2026.

The bottom line

This screener gives Celestica Inc. (TSX: CLS) a FAIL. Its electronics-manufacturing business is fine on its own, and both ratio gates pass (debt ~1.8%, interest income ~0.08%) — but the company-confirmed Aerospace and Defense business inside its ATS segment fails gate one. Snapshot dated September 29, 2026; re-checked quarterly after earnings — exiting the defence business would change this gate.
