Opposing evidence
The profit margin narrowed
The latest quarterly operating margin was 17.2%, -2.5 percentage points from a year earlier. Compare the sales and margin contributions below.
Year-to-date profit is lower
Across 2 completed quarters since 2025-12-31, net income was 5,700.0m versus 14,498.0m in the matching prior-year periods (USD). Check whether the latest quarter changes that direction.
The original scenarios
| Scenario | Sales growth | Profit margin | Model value |
|---|---|---|---|
| Weaker | -5.0% | 15.6% | $45.91 |
| Central | 0.0% | 17.3% | $73.49 |
| Stronger | 5.0% | 19.0% | $111.12 |
Method: Cash flow across the cycle. Loss periods, gaps or differences in the earnings basis make P/E less useful here. This assessment uses operating profit, capital spending and the balance sheet instead. Loss years remain in the margin history. These scenarios are not probability intervals.

Recent price · Passed. Weekly close dated 2026-09-04.
Current financials · Passed. Statements through 2026-06-30; factor prices dated 2026-09-04.
Price risk · Passed. Risk uses the latest 52 weekly price changes.
Operating history · Passed. 5 annual results, retaining operating losses and unusually strong years.
Quarterly operating results · Passed. Four quarters through 2026-06-30.
Cash-flow and ownership inputs · Passed. Capital spending, depreciation estimate, operating capital, debt, cash and other ownership claims are recorded.
Depreciation basis · Passed. Four matching quarters of operating income and reported depreciation are required. An unrelated EBITDA-minus-EBIT difference is not treated as depreciation.
Matching currency · Passed. USD statements and share price.
Operating totals · Passed. Quarterly sales and operating profit agree with the trailing snapshot within 5%.
Operating discount rate · Passed. The operating cash-flow discount rate needs a current USD Treasury rate, at least two years of matching market returns, and dated debt and share inputs. An equity return hurdle is not used as the company's funding cost.
Continuing growth and funding cost · Passed. The funding cost must exceed continuing growth in every valuation scenario.
Scenario consistency · Passed. The weaker, central and stronger assumptions must give an ordered range. When growth costs more capital than it earns, a tailored operating review is required before publishing a target.
Target publication review · Passed. The model estimate is within SM's automatic publication range of one quarter to four times the current price. This is a review threshold, not evidence that the market price is correct.
Cash-flow value dependence · Passed. Cash flows beyond year five account for 83.8% of the absolute present value. This is within SM's 90% automatic publication limit.
