核心理念："财报是用来排除企业的"

一句话：Alliant Energy是爱荷华/威斯康星中型受管制公用事业。它是同组中最干净的公用事业——仅1项红旗（现金对债务）、零真正的盈利异常。营收增9.6%至$4.36B，净利润增17.4%至$810M。零商誉、同行最佳净利率（18.6%）和ROE（11.0%）。F评级仅由C4（现金对债务）的单一关键代码未通过驱动，对所有公用事业都是结构性的。实际上更公平的评级应为C级。

Asset valuation charge: IPL recorded a $60M charge for its Lansing Generating Station in FY2025 — a one-time 减值 of a legacy coal/gas plant.
利息费用: Grew from $394M to $512M (+30%) over two years, reflecting the expanding debt load. Alliant Energy and AEF "expect to issue up to $400 million of long-term debt in aggregate" in 2026. AEF has "$500 million ($300 million term loan was retired in January 2026) and $575 million, respectively, of long-term debt maturing in 2026."
分红 increase: 根据10-K年报: "Alliant Energy announced a 5% increase in its targeted 2026 annual common stock 分红 to $2.14 per share."
| Metric | FY2022 | FY2023 | FY2024 | FY2025 | 趋势 |
|---|---|---|---|---|---|
| 营收 | $4.21B | $4.03B | $3.98B | $4.36B | 增长中 |
| 净利润 | $686M | $703M | $690M | $810M | Steadily 增长中 |
| 毛利率 | 40.6% | 43.1% | 44.7% | 45.7% | Expanding |
| 净利率 | 16.3% | 17.5% | 17.3% | 18.6% | 改善中 |
| ROE | 10.9% | 10.4% | 9.9% | 11.0% | 稳定 |
The net margin of 18.6% and ROE of 11.0% are 最强的 in this peer group — reflecting Alliant Energy's efficient operations and favorable regulatory outcomes.
现金流
| Metric | FY2022 | FY2023 | FY2024 | FY2025 |
|---|---|---|---|---|
| 经营现金流 | $486M | $867M | $1,167M | $1,169M |
| CFFO / NI | 0.71 | 1.23 | 1.69 | 1.44 |
| 现金余额 | $20M | $62M | $81M | $556M |
CFFO/NI of 1.44 is lower than the other utilities in this group (typical range 2.0-3.6), which is notable. The lower ratio partly reflects Alliant Energy's lower D&A relative to 净利润. Cash improved significantly to $556M from $81M, the best cash position among this peer group.

收入质量
| # | 检查项 | 结果 | 说明 |
|---|---|---|---|
| A1 | 应收周转天数(DSO) | ✅ 通过 | 11 days, +1 day YoY |
| A2 | 应收 vs 营收增速 | **⚠️ 关注** | AR growth 22.9% vs revenue growth 9.6% |
| A3 | 营收 vs 现金流 | ✅ 通过 | Revenue +9.6%, CFFO +0.2% |
A2: AR growing at 22.9% versus 营收 at 9.6% is a mild anomaly. DSO increased by only 1 day to 11 days, so the absolute AR level remains very low. This could reflect timing of customer billing cycles or seasonal weather-related billing at year-end.

| C4 | 现金覆盖债务 | **❌ 未通过** | Cash $556M covers 5% of $12.1B debt |
C4: The only red flag. Cash of $556M against $12.1B debt is the standard utility capital structure. Alliant Energy has the best cash/debt ratio (5%) in this group, but it still triggers the threshold.
资产负债表
| # | 检查项 | 结果 | 说明 |

D1: Zero 商誉 is 最干净的 balance sheet in this peer group. Alliant Energy grew organically rather than through acquisitions.

德勤关键审计事项: Rate Regulation
根据审计报告: "We identified the impact of rate regulation as a critical audit matter due to the significant judgments made by management to support its assertions about the impact of rate regulation on the financial statements, including management's assertions about impacted account balances, the probability of recovery in future rates of incurred costs, and the probability of a future reduction in rates or refund to customers."
Deloitte also evaluated "the Company's disclosures related to the impacts of rate regulation and regulatory developments, including disclosures related to certain regulatory balances recorded."
关键风险
1. IPL rate moratorium. The 10-K mentions "the impact of IPL's retail electric base rate moratorium" — a period during which IPL cannot increase base electric rates. This constrains 营收 growth while costs continue rising.
2. Lansing Generating Station 减值. The $60M asset valuation charge for Lansing signals ongoing risk from legacy generation asset retirements.
3. Rising 利息费用. 利息费用 grew 30% over two years ($394M to $512M), with $975M+ in debt maturing in 2026 requiring refinancing at likely higher rates.

Grade: F — the mildest F in this utility batch. Borderline C grade.
Alliant Energy is 最干净的 utility in this peer group by far. Only one red flag (cash vs debt), zero 商誉, best net margin (18.6%), best ROE (11.0%), and the only utility with improving cash position. The F grade is driven by the single critical-code fail on C4 (cash vs debt), which is structural for all utilities. In practice, Alliant Energy would more fairly grade as a C — some concerns to investigate, but no genuine earnings quality issues.
