Grade: F — Three Red Flags Including Persistent FCF Weakness
Framework: Schilit *Financial Shenanigans* + Beneish M-Score + forensic accounting principles
Data: SEC EDGAR 10-K (Filed January 28, 2026, FY ended December 31, 2025) + Yahoo Finance
Auditor: Ernst & Young LLP — Unqualified opinion (1 critical audit matter: Valuation of goodwill)
One-line verdict: United Rentals grew revenue 4.9% to $16,099M on the back of fleet expansion and pricing, with CFFO of $5,190M and CFFO/NI of 2.08x. But three checks fail: FCF has been below 50% of net income for three consecutive years (the rental fleet CapEx model consumes cash), cash of $459M covers only 3% of $15.7B debt, and goodwill at 85% of equity. The business model explains these numbers — rental companies must continuously invest in fleet to maintain revenue — but the screening framework treats persistent FCF weakness as a signal. The M-Score of -2.84 is very clean, the Z-Score of 3.05 is in the safe zone, and the F-Score fraud probability is low at 0.22%. EY flagged goodwill valuation with discount rate sensitivity for a certain reporting unit.

The Equipment Rental Roll-Up
United Rentals is the world's largest equipment rental company, with approximately 15% North American market share. The company rents construction and industrial equipment to a diversified customer base — no single customer exceeds 1% of revenue, and the top 10 customers represent only 5%.
Equipment rental revenue comprises 86% of total revenue. Per the 10-K performance metrics: "Year-over-year change in average original equipment cost (OEC) 3%." The company's largest supplier represents 11% of CapEx, with the top 10 at 52%.
In early 2025, URI received a $64M break-up fee after the H&E Equipment Services merger agreement was terminated. The 10-K notes: "Our results for the year ended December 31, 2025 include a net $39 merger termination benefit, which reflects this break-up fee, net of related transaction costs."
EY's critical audit matter: goodwill valuation. With $7.1B of goodwill, "the fair value estimates were sensitive to changes in the risk-adjusted discount rate for a certain reporting unit." Small changes in discount rate assumptions could trigger impairment.
Financial Performance: Growth Continues
| Metric | FY2025 | FY2024 | FY2023 | FY2022 |
|---|---|---|---|---|
| Total Revenue | $16,099M | $15,345M | $14,332M | $11,642M |
| Gross Profit | $6,144M | $6,150M | $5,813M | $4,996M |
| Gross Margin | 38.2% | 40.1% | 40.6% | 42.9% |
| Operating Income | $3,974M | $4,068M | $3,855M | $3,232M |
| Net Income | $2,494M | $2,575M | $2,424M | $2,105M |
| EBITDA | $7,162M | $6,982M | $6,627M | $5,464M |
| Interest Expense | $716M | $691M | $635M | $445M |
Revenue grew 4.9%, but gross margin compressed from 40.1% to 38.2% — a 190bp decline. This is the second consecutive year of margin compression (from 40.6% to 40.1% to 38.2%), a cumulative 240bp decline over two years. The MD&A should be watched for comments on rental rate trends and fleet utilization.
Net income dipped 3.1% from $2,575M to $2,494M. Operating income also declined from $4,068M to $3,974M. Revenue is growing but profitability is eroding — a margin compression pattern.
Cash Flow: The Rental CapEx Trap
| Metric | FY2025 | FY2024 | FY2023 | FY2022 |
|---|---|---|---|---|
| Operating Cash Flow | $5,190M | $4,546M | $4,704M | $4,433M |
| CapEx | $(4,528)M | $(4,127)M | $(4,070)M | $(3,690)M |
| Free Cash Flow | $662M | $419M | $634M | $743M |
| Buybacks | $(1,969)M | $(1,571)M | $(1,070)M | $(1,068)M |
| Dividends | $(464)M | $(434)M | $(406)M | $0 |
| D&A | $3,108M | $2,903M | $2,781M | $2,217M |
The C2 fail explained: FCF/NI has been below 50% for three consecutive years: 26.5% ($662M/$2,494M) in FY2025, 16.3% in FY2024, 26.2% in FY2023. This is a structural feature of the equipment rental business — CapEx of $4,528M (89% of CFFO) goes to purchasing rental fleet equipment that generates revenue.
The high D&A ($3,108M) reflects the depreciating fleet. CFFO/NI of 2.08x is excellent because depreciation is a large non-cash charge. But FCF after fleet CapEx is thin.
Buybacks of $1,969M exceed FCF of $662M by $1,307M — funded by debt. Add dividends of $464M, and total shareholder returns of $2,433M are 3.7x FCF. This is aggressive capital allocation for a company with 3% cash-to-debt coverage.
Balance Sheet: Leveraged Rental Fleet
| Item | Dec 31, 2025 | Dec 31, 2024 |
|---|---|---|
| Cash & Equivalents | $459M | $457M |
| Accounts Receivable | $2,510M | $2,357M |
| Inventories | $240M | $200M |
| Total Current Assets | $3,608M | $3,249M |
| Goodwill | $7,119M | $6,900M |
| Other Intangible Assets | $477M | $663M |
| Total Assets | $29,866M | $28,163M |
| Total Debt | $15,670M | $14,789M |
| Total Liabilities | $20,898M | $19,541M |
| Stockholders' Equity | $8,968M | $8,622M |
| Retained Earnings | $15,843M | $13,813M |
Cash of $459M is minimal. Total debt grew $881M to $15.7B. Goodwill of $7.1B at 85% of equity reflects serial acquisitions — URI has built its market position through M&A. EY's CAM notes discount rate sensitivity for a specific reporting unit.
Debt/EBITDA of 2.2x is actually healthy for the sector, and interest coverage of 5.6x provides adequate margin. The leverage is supported by the depreciable rental fleet assets — unlike goodwill, fleet equipment has real liquidation value.

Key Risks from the 10-K
1. Goodwill Valuation — EY's Critical Audit Matter
EY identified goodwill valuation as the CAM, noting that fair value estimates for a certain reporting unit were "sensitive to changes in the risk-adjusted discount rate." The determination of the discount rate "involved significant judgment." A small increase in the discount rate could trigger an impairment of the $7.1B goodwill balance.
2. Construction Cycle Sensitivity
Equipment rental demand is tied to construction and industrial activity. An economic downturn would reduce rental rates and fleet utilization while the fleet continues to depreciate and debt continues to accrue interest. The 240bp gross margin compression over two years may already signal softening demand.
3. Capital Allocation Aggressiveness
Buybacks of $1,969M plus dividends of $464M total $2,433M against FCF of $662M. The $1,771M shortfall is funded by debt. This pattern — returning capital far in excess of free cash flow in a business with compressing margins — is the classic risk for leveraged roll-ups.
4. Tariff and Supply Chain Impact
The 10-K risk factors mention "tariffs, trade wars and sanctions" as factors that could affect results. Fleet equipment procurement costs could rise with tariffs on imported machinery.
Summary
Grade: F. Three red flags: FCF below 50% of NI for three consecutive years, cash covering only 3% of $15.7B debt, and goodwill at 85% of equity.
The M-Score of -2.84 is the cleanest in this batch, confirming no manipulation. The F-Score fraud probability of 0.22% is very low. The earnings are real — the issue is the capital structure and cash flow reinvestment requirements, not earnings quality.
URI's business model requires continuous CapEx to maintain the rental fleet, which structurally consumes most operating cash flow. The company then borrows to fund buybacks and dividends. This works beautifully in an expanding construction market but creates significant risk in a downturn when rental rates and utilization fall while debt obligations remain fixed.
The two-year gross margin compression trend (42.9% to 40.1% to 38.2%) is the most important operating signal. If margins continue to decline while debt grows, the financial structure comes under real pressure.
