基本面分析
基本面核心结论是：盈利能力可观，但必须把增长放缓与估值压力放在一起看。
最近可用期间收入为4,668 亿美元，同比增长6.4%。拉长到三年，收入年均变化为1.8%，自由现金流年均变化为-3.9%。
盈利质量由净利率27.6%、ROIC133.8%和自由现金流利润率29.3%体现。ROIC意味着每投入一元资本，约产生1.34元税后经营利润。
估值是主要压力点：市盈率为34.6倍，市销率为9.5倍，市净率为60.4倍，EV/EBITDA为26.7倍。与自身五年历史相比，市销率、市净率、EV/EBITDA等倍数分别位于第 100、100、100 百分位；其中市销率、市净率、EV/EBITDA处于五年来最贵水平。
DCF在9.33%折现率和2.50%终值增长率假设下给出每股88.41 美元的公允价值。终值现值占企业价值71.70%，因此长期假设对结果影响很大。
下面的7×5敏感性表展示折现率和终值增长率同时变化时，每股DCF公允价值如何变化：
| WACC\g | 1.50% | 2.00% | 2.50% | 3.00% | 3.50% |
| --- | --- | --- | --- | --- | --- |
| 7.83% | 98.77 | 105.49 | 113.47 | 123.10 | 134.95 |
| 8.33% | 91.46 | 97.09 | 103.69 | 111.52 | 120.98 |
| 8.83% | 85.14 | 89.92 | 95.45 | 101.92 | 109.62 |
| 9.33% | 79.64 | 83.73 | 88.41 | 93.84 | 100.20 |
| 9.83% | 74.79 | 78.32 | 82.34 | 86.94 | 92.27 |

| 10.83% | 66.65 | 69.35 | 72.37 | 75.78 | 79.65 |
公允价值由 6 种方法交叉验证得出：DCF、P/E、P/S、P/B、EV/EBITDA、P/FCF。区间为88.41 美元至270.45 美元，分散度为0.78。
质量分数仅作为支持性证据，不进入综合评级。Piotroski F-score（皮奥特罗斯基）为8/9项可测试标准（强）；标准：1 ROA > 0=1（ROA=0.3118）；2 CFO > 0=1（CFO=111,482）；3 ROA improved YoY=1（ROA=0.3118、prior_ROA=0.2568）；4 CFO > net income=0（CFO=111,482、net_income=112,010）；5 total debt / assets fell YoY=1（debt_assets=0.2746、prior_debt_assets=0.2922）；6 current ratio improved YoY=1（current_ratio=0.8933、prior_current_ratio=0.8673）；7 no net new shares issued=1（diluted_shares=15,004,697,000、prior_diluted_shares=15,408,095,000）；8 gross margin improved YoY=1（gross_margin=0.4691、prior_gross_margin=0.4621）；9 asset turnover improved YoY=1（asset_turnover=1.1584、prior_asset_turnover=1.0714）；已排除：无。Altman Z为10.27（安全）；组成项为X1 -0.0492，X2 -0.0397，X3 0.3704，X4 13.3442，X5 1.1584。Altman Z源自1960年代制造业样本；对于市值较大、资产较轻的公司，X4可能显著抬高分数。因此Z=10并不表示其安全性是Z=3公司的三倍。盈利一致性为一致：EPS为正的年度4/4个可比年度（共5个年度，其中1个缺少EPS数据，已排除而非计为亏损），EPS同比上升2/3次，变异系数为0.091。 | Fundamental analysis
Operating quality is the central question: profitability is measurable, but the growth and valuation evidence must be read together.
Revenue remains positive at $466.8B for the latest available period, up 6.4% year on year. Over three years, revenue has grown 1.8% annualised while FCF has changed -3.9%.
Profitability is described by a net margin of 27.6%, ROIC of 133.8%, and FCF margin of 29.3%. ROIC means that each dollar of invested capital produces about 1.34 dollars of after-tax operating profit.
Valuation is the main pressure point: P/E is 34.6 times, P/S is 9.5 times, P/B is 60.4 times, and EV/EBITDA is 26.7 times. Against its own five-year history, P/S, P/B, EV/EBITDA sit at the 100th, 100th, 100th percentiles; P/S, P/B, EV/EBITDA are at their most expensive in five years.
DCF produces a fair value of $88.41 per share using a 9.33% discount rate and 2.50% terminal growth assumption. Terminal value represents 71.70% of enterprise value, so the result is especially sensitive to long-term assumptions.
The following 7×5 sensitivity table shows how the per-share DCF value changes when the discount rate and terminal growth assumption move together:
| WACC\g | 1.50% | 2.00% | 2.50% | 3.00% | 3.50% |
| --- | --- | --- | --- | --- | --- |
| 7.83% | 98.77 | 105.49 | 113.47 | 123.10 | 134.95 |
| 8.33% | 91.46 | 97.09 | 103.69 | 111.52 | 120.98 |
| 8.83% | 85.14 | 89.92 | 95.45 | 101.92 | 109.62 |
| 9.33% | 79.64 | 83.73 | 88.41 | 93.84 | 100.20 |
| 9.83% | 74.79 | 78.32 | 82.34 | 86.94 | 92.27 |
| 10.33% | 70.49 | 73.57 | 77.04 | 80.98 | 85.50 |
| 10.83% | 66.65 | 69.35 | 72.37 | 75.78 | 79.65 |
The fair value triangulates 6 methods: DCF, P/E, P/S, P/B, EV/EBITDA, P/FCF. The range is $88.41 to $270.45, with a dispersion of 0.78.
Quality scores are supporting evidence only and do not enter the rating. Piotroski F-score is 8/9 testable criteria (strong); criteria: 1 ROA > 0=1 (ROA=0.3118); 2 CFO > 0=1 (CFO=111,482); 3 ROA improved YoY=1 (ROA=0.3118, prior_ROA=0.2568); 4 CFO > net income=0 (CFO=111,482, net_income=112,010); 5 total debt / assets fell YoY=1 (debt_assets=0.2746, prior_debt_assets=0.2922); 6 current ratio improved YoY=1 (current_ratio=0.8933, prior_current_ratio=0.8673); 7 no net new shares issued=1 (diluted_shares=15,004,697,000, prior_diluted_shares=15,408,095,000); 8 gross margin improved YoY=1 (gross_margin=0.4691, prior_gross_margin=0.4621); 9 asset turnover improved YoY=1 (asset_turnover=1.1584, prior_asset_turnover=1.0714); excluded: none. Altman Z is 10.27 (safe); components X1 -0.0492, X2 -0.0397, X3 0.3704, X4 13.3442, X5 1.1584. Altman Z was calibrated on 1960s manufacturers; it can be inflated for asset-light companies with large market caps because X4 dominates. Therefore Z=10 does not mean the company is three times safer than a company at Z=3. Earnings consistency is consistent: positive EPS years 4/4 testable (of 5 annual periods; 1 lacking EPS data and excluded, not counted as losses), EPS increases 2/3 comparisons, coefficient of variation 0.091. |
