AUTOZONE INC

AutoZone's fiscal 2025 balance sheet, as filed with the SEC and read on August 15, 2026, shows stockholders' equity of negative $3.4 billion — total debt of $8.8 billion against $272 million of cash, inside $19.4 billion of total assets; the normalized series on this page carries $8.8B of total debt. Negative book equity records an accumulated accounting deficit; by itself, it does not establish insolvency or liquidation value. The same page scores AutoZone 81.7 out of 100 — a wide moat, ranked #36 of 487 scored Consumer Discretionary companies. The narrower paradox is useful: a negative owners' equity account beside a wide-moat score, both drawn from the filed financial history.

The accounting line is incomplete as a picture of the operating business. What it cannot show is what the capital still inside the business earns. The returns-on-capital filter gives AutoZone 100 out of 100 — the strongest sub-score on the card — and the registry's own reading is: Median ROIC 60.2%, above the 12% hurdle in 100% of years. A business earning a median 51 cents per invested dollar across 14 filed years doesn't need much book equity. It manufactures the cash equity would otherwise have to supply.

The operating record behind that number is on the same page. Revenue and EPS trend scores 93 (2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue 14629585000.00 to 18938717000.00, increasing; diluted EPS 95.19 to 144.87, increasing.), and pricing power scores 89 on Median gross margin 52.7% over 10y, very stable. EPS growing faster than revenue over the same window is per-share arithmetic, not a separate claim: fewer shares, same profit pool.

Fewer shares is the deliberate part. AutoZone's board has authorized $42.2 billion of share repurchases since the program began in 1998, per the company's own June 16, 2026 press release announcing its latest $1.5 billion addition. Those buybacks are what drove book equity below zero — retiring stock at market prices far above its carrying value drains the equity account even as the business grows. The capital-allocation filter scores the result 86 (Owner earnings +8.1%/yr, share count shrinking (buybacks).).

So how does the balance-sheet filter handle a company with negative book value? It doesn't fail it, and it doesn't ignore the debt either. Balance-sheet safety scores 40 out of 100 — the weakest of the five filters — on Net debt/EBITDA 2.0x, interest coverage 7x. The filter measures whether cash flow services the debt, not whether book equity is positive. The negative equity does surface elsewhere on the page as pure arithmetic noise: return on equity and the equity multiplier both flip sign on a negative denominator rather than on losses. The registry reports it without dressing it up.

The current fiscal year says the machine still runs. In its third-quarter fiscal 2026 release dated May 26, 2026, AutoZone reported net sales of $4.8 billion, up 8.4%, with domestic same-store sales up 4.1% and EPS of $38.07; the company opened 82 stores in the quarter to reach 7,856 worldwide. The commercial side — parts sold to repair shops rather than to weekend mechanics — represented 31.7% of domestic auto-parts sales in fiscal 2025, per the company's Form 10-K for the year ended August 30, 2025.

One thing the registry won't do is price it. The valuation module abstains: the value-if-growth-stopped estimate on this page reads as unavailable for want of owner-earnings data, and against a recent price of $2957.41 the page renders no price-versus-value verdict at all. The registry doesn't guess. An abstention is not an endorsement of the price, and a reader should treat that price as unanchored by any baseline on this page.

That leaves the remainder of the paradox — the part the filed financial history resolves in AutoZone's favor only for as long as two conditions hold. First, the debt structure works because coverage holds; the same obligation sits on a business with no book-equity cushion, so a durable drop in earnings would expose that thin accounting cushion. The 40 is the registry pricing exactly that asymmetry. Second, the demand base: the parts that fill those 7,856 stores serve combustion-engine vehicles, and what an increasingly electric fleet does to per-vehicle parts demand is a question no AutoZone filing on this page answers. Neither risk is hypothetical. Neither is scored away. They're simply outweighed, on the current filed financial history, by returns on capital that a balance-sheet convention was never built to describe.

A company can report negative book equity and still generate strong operating returns. That's the claim this score makes. The filings will keep grading it.
