Grade: F — Major Red Flags
Framework: Schilit *Financial Shenanigans* + Beneish M-Score + forensic accounting principles
Data: SEC EDGAR 10-K (Filed 2026-02-23, FY ended December 31, 2025) + Yahoo Finance
Auditor: PricewaterhouseCoopers LLP — Unqualified opinion (1 critical audit matter: pension projected benefit obligation)
One-line verdict: Ecolab's operating performance is strong — gross margin expanded to 44.5%, adjusted diluted EPS grew 13% to $7.53, and cash flow from operations hit $3.0 billion — but the screening engine flags two structural issues: goodwill plus intangibles at 132% of equity (exceeding total shareholder equity) and cash covering only 7% of $9.0B total debt. These are not signs of fraud or manipulation — the M-Score is clean at -2.51 — but structural features of a company built through serial acquisitions (Nalco, Purolite, Ovivo Electronics) financed predominantly with debt. The business quality is high; the balance sheet structure demands monitoring.

Four Segments, One Business Model
Per the filing, Ecolab operates four reportable segments:
| Segment | FY2025 Sales | FY2024 Sales | Operating Income | Margin |
|---|---|---|---|---|
| Global Water | $7,679.9M | $7,483.4M | $1,263.9M | 16.5% |
| Global Institutional & Specialty | $5,962.0M | $5,979.4M | $1,357.8M | 22.8% |
| Global Pest Elimination | $1,219.2M | $1,140.1M | $237.1M | 19.4% |
| Global Life Sciences | $706.1M | $670.5M | $120.7M | 17.1% |
Per the filing, "Sales of warewashing products were approximately 13% of consolidated net sales in 2025." The business model centers on recurring chemical and service delivery to institutional and industrial customers — a sticky, high-margin business with 48,000 employees including "more than 25,000 sales and service employees."
Profitability: Consistent Expansion
| Metric | FY2023 | FY2024 | FY2025 | Trend |
|---|---|---|---|---|
| Revenue | $15,320M | $15,741M | $16,081M | +5.0% over 3 years |
| Net Income (GAAP) | $1,372M | $2,112M | $2,076M | FY2024 included $127M gains |
| Adjusted Net Income | $1,492M | $1,907M | $2,149M | +13% YoY |
| Gross Margin | 40.2% | 43.5% | 44.5% | Rising 3 consecutive years |
| Adjusted EPS | $5.24 | $6.65 | $7.53 | +13% |
Per the filing: "Adjusted diluted EPS, which excludes the impact of special (gains) and charges, discrete tax items and the Ovivo Electronics acquisition increased 13% to $7.53 in 2025 compared to $6.65 in 2024 which reflected good organic sales growth and robust operating income margin expansion."
GAAP net income dipped 2% because FY2024 included $126.7M in after-tax special gains, while FY2025 had $127.4M in after-tax special charges. The underlying adjusted trend is clearly positive.
The "One Ecolab" restructuring initiative generated charges of $140.2M in special charges plus $7.7M in cost of sales for FY2025.
Cash Flow: Strong and Growing
| Metric | FY2023 | FY2024 | FY2025 |
|---|---|---|---|
| Operating Cash Flow | $2,412M | $2,814M | $2,953M |
| Net Income | $1,372M | $2,112M | $2,076M |
| CFFO / NI | 1.76 | 1.33 | 1.42 |
| CapEx | $775M | $995M | $1,048M |
| Free Cash Flow | $1,637M | $1,819M | $1,904M |
Per the filing: "Cash flow from operating activities was $3.0 billion in 2025, compared to $2.8 billion in 2024. We continued to generate strong cash flow from operations, allowing us to fund our ongoing operations, investments in our business, acquisitions, debt repayments, pension obligations and return cash to our shareholders through share repurchases and dividend payments."
CFFO/NI of 1.42 confirms earnings are backed by cash. FCF of $1.9B represents a 12% margin on revenue — solid for a services-heavy business.
The 18-Point Screening
Revenue Quality
| # | Check | Result | Detail |
|---|---|---|---|
| A1 | DSO Change | ✅ | DSO 74 days, +7 days YoY |
| A2 | AR vs Revenue Growth | ⚠️ | AR growth 13.4% exceeds revenue growth 2.2% |
| A3 | Revenue vs CFFO | ✅ | Revenue +2.2%, CFFO +4.9% |
A2 — AR growing faster than revenue. The gap (13.4% vs. 2.2%) is notable. Part of this is the Ovivo Electronics acquisition, which added $79.4 million in acquired receivables. Part may reflect extended terms for institutional customers. DSO of 74 days is relatively high and increased 7 days year-over-year — the full trend deserves monitoring.
Expense Quality
| # | Check | Result | Detail |
|---|---|---|---|
| B1 | Inventory vs COGS | ✅ | Inventory +1.7% vs COGS +0.3% |
| B2 | CapEx vs Revenue | ✅ | CapEx +5.4% vs revenue +2.2% |
| B3 | SG&A Ratio | ✅ | SG&A/Gross Profit = 59.5%. Normal |
| B4 | Gross Margin | ✅ | 44.5%, +1.0pp expansion |
Cash Flow Quality

|---|---|---|---|
| C1 | CFFO vs Net Income | ✅ | CFFO/NI = 1.42 |
| C2 | Free Cash Flow | ✅ | FCF $1.9B, FCF/NI = 0.92 |
| C3 | Accruals Ratio | ✅ | -3.6%. Clean |
| C4 | Cash vs Debt | ❌ | Cash $0.6B covers only 7% of debt $9.0B |
C4 — Razor-thin cash vs. massive debt. Cash of $646M against total debt of $9.0B is a 7% coverage ratio — the worst in this batch. Per the filing: "Total debt was $8.2 billion as of December 31, 2025 and $7.6 billion as of December 31, 2024." Debt increased by $672M year-over-year, partially to fund the Ovivo Electronics acquisition ($1.6 billion).
However, the filing shows net debt to EBITDA improved, and Ecolab targets "A range ratings metrics over the long-term." With $3.0B annual operating cash flow, the debt is serviceable — but the cash cushion is essentially nonexistent.
Balance Sheet
| # | Check | Result | Detail |
|---|---|---|---|
| D1 | Goodwill + Intangibles | ❌ | $12.9B = 132% of equity |
| D2 | Leverage | ✅ | Debt/EBITDA = 2.3x |
| D3 | Soft Asset Growth | ⚠️ | Other assets grew 30.0% vs revenue 2.2% |
| D4 | Asset Impairment | — | No write-off data |
D1 — Goodwill exceeds total equity. Goodwill of $9,227M plus intangible assets of $3,689M totals $12.9B against equity of approximately $9.8B. This 132% ratio is the highest in this batch. The goodwill comes from three major acquisitions: Nalco (2011), Purolite (2021), and Ovivo Electronics (2025, $1.6B). The filing warns: "We maintain goodwill of $9.2 billion which is maintained in various reporting units, including goodwill from the Nalco, Purolite and Ovivo Electronics transactions."
D3 — Other asset growth. Other noncurrent assets grew from $670M to $783M (+30%), driven by operating lease assets ($766M vs. $723M) and other items. The Ovivo Electronics acquisition contributed to this growth.

Key Risks from the 10-K
1. Acquisition Integration — Ovivo Electronics
The $1.6 billion Ovivo Electronics acquisition adds a fast-growing ultrapure water technology business for semiconductor manufacturing. Per the filing, Ovivo is "a leading and fast-growing global provider of breakthrough ultrapure water technologies for semiconductor manufacturing." Integration risk exists, and the $1.1B in goodwill from this single deal is substantial.
2. Pension Obligations — The Auditor's Critical Audit Matter
PwC identified the "Valuation of Projected Benefit Obligation — U.S. Qualified Pension Plan" as the critical audit matter. Net losses on pension plans were $486 million as of December 31, 2025. The discount rate and return on assets assumptions significantly impact the obligation and future expense.
3. One Ecolab Restructuring Costs
The "One Ecolab" initiative generated $148M in total charges ($7.7M in COGS, $140.2M in special charges). While restructuring to improve efficiency is positive long-term, the multi-year program carries execution risk.
4. International Exposure
Per the filing, a significant portion of net sales were generated from customers outside the United States, exposing the company to currency fluctuations, trade policy changes, and tariff risks.
Summary
Grade: F. Exceptional operating quality masked by an acquisition-built balance sheet where goodwill exceeds total equity and cash covers only 7% of $9B in debt.
Ecolab is a high-quality business by operating metrics: expanding gross margins (44.5%), growing adjusted EPS (+13%), strong CFFO/NI (1.42), and clean M-Score (-2.51). The F grade is structural, not operational — it reflects the cumulative impact of decades of acquisition-driven growth (Nalco, Purolite, Ovivo) financed by debt. Goodwill at 132% of equity means any impairment would exceed the balance sheet's equity cushion. Cash at 7% of debt means the company has zero margin for a liquidity event. For investors, Ecolab's quality is in the income statement; its risk is in the balance sheet.
