1.1 Business Segment Mix & Unlevered Beta
| Segment | % of Segment Earnings | Unlevered Beta | Weighted Contribution |
|---|
Weighted by segment earnings, not revenue — deliberately. Imperial is vertically integrated: Downstream buys almost all of its crude from Upstream, so on an external-revenue basis Downstream is 97% of the company (C$27,603M of C$28,397M) and Upstream is under 1%. That mix would say nothing about where the risk sits. Segment pre-tax earnings for H1 2026 — Upstream C$2,310M, Downstream C$1,829M, Chemical C$118M (10-Q Note 8) — give the split shown above. Not auto-updated when a new filing is dropped in — re-read Note 8 and update here. Betas are judgement: oil-sands production carries direct crude-price exposure, refining margins are counter-cyclical to crude and so damp the swing, and chemicals sit in between. Chemical is under 3% of earnings and barely moves the result.
1.2 Relevering Beta for Imperial Oil's Capital Structure
Total Debt: C$3,988M | Market Value of Equity: C$85,000M | Tax Rate: 23.5%
Levered Beta = Unlevered Beta × [1 + (1 - Tax Rate) × D/E]
= 0.769 × [1 + (1 - 0.23) × (16,593/22,034)]
= 0.769 × [1 + 0.77 × 0.753]
= 0.769 × 1.580
= 1.214
