Understand why the debt-to-equity ratio is the most misunderstood stability variable
10x Insight
Debt-to-equity ratio (D/E) = Interest-bearing debt / Equity × 100.
The nature of debt — why it exists
Debt is neither bad nor good — it is a tool. A company borrows money to invest in growth it cannot finance with equity. If the return on the investment exceeds the interest cost, debt creates value for shareholders. If the return is below the interest cost, debt destroys value. This is the fundamental equation: debt is positive leverage when ROIC > WACC, and negative leverage when ROIC < WACC. The debt-to-equity ratio (D/E) measures how much of the company's capital structure comes from liabilities (loans) vs equity. A company with a debt-to-equity ratio of 100% has as much debt as equity — the company is financed 50/50. A company with a debt-to-equity ratio of 50% has one third debt and two thirds equity. The higher the D/E, the more leverage — and the more risk in crises.
📖 DEFINITION
Debt-to-equity ratio (D/E) = Interest-bearing debt / Equity × 100. Measured in percent. AKM1: p1 = >150% (very high), p2 = 100-150% (high), p3 = 50-100% (normal), p4 = 20-50% (low), p5 = <20% or net cash.
Why stability is an AKM1 category
AKM1 has five categories: Valuation, Growth, Profitability, Stability, Moat. Stability is the category that answers the question: 'can the company survive a crisis?'. A company can have fantastic growth, profitability, and valuation — but if it has high debt, low liquidity, and volatile cash flow, it can go under in the next recession. Stability is insurance against catastrophe. The debt-to-equity ratio is the first of three stability variables because it measures the biggest risk: the interest burden. A company with a debt-to-equity ratio of 200% may pay 8% of revenue in interest rate costs — if revenue falls 30%, the interest can exceed gross profit and the company goes bankrupt. A debt-to-equity ratio >150% has historically been the strongest single predictor of bankruptcy among industrial companies.
💡 INSIGHT
A debt-to-equity ratio >150% has historically been the strongest single predictor of bankruptcy among industrial companies. High debt = higher interest cost = higher break-even revenue = less margin for error.
Industry-dependent — not one size for all
The debt-to-equity ratio is always interpreted in industry context. Banks' D/E is normally 8-12x (they have deposits as 'debt' but these are interest-bearing and constitute their business model). Property companies typically have 50-70% debt-to-equity ratio (properties are collateral, long-term operations). Industrial companies should have <50% (cyclical, need a buffer). SaaS companies should have <20% or net cash (low capital base, scalability). Comparing Swedbank (D/E ~10x) with Atlas Copco (D/E ~30%) is meaningless — they have different business models. Industry comparison is the only reasonable interpretation. The AKM1 score is based on these industry reference values: a property company with 60% D/E gets score 4, an industrial company with 60% D/E gets score 3.
⚡ KEY INSIGHTS Debt is positive leverage when ROIC > WACC, negative when ROIC < WACC D/E >150% is the strongest single bankruptcy predictor for industrial companies Industry context is decisive — banks 10x, property 50-70%, industry <50%, SaaS <20% Stability in AKM1 = 'can the company survive a crisis?' — debt is the first risk 2
