Sunrun (RUN) Flagged for High Risk on Negative Margins, Cash Burn, and $14.85B Debt Load

Sunrun Inc. (RUN) faces elevated risk due to persistent operating losses, negative free cash flow, and high leverage, analysts said on June 2, 2026, urging caution despite the stock’s 14.7% decline over the past six months to $15.52. The S&P 500 gained 11% in the same period. The residential solar company’s five-year average operating margin stands at negative 60.4%, signaling deep unprofitability. Its free cash flow margin averaged negative 30.5% over that stretch, draining resources. Sunrun’s balance sheet carries $14.85 billion in debt against $1.09 billion in cash, resulting in a net-debt-to-EBITDA ratio of 20× based on trailing 12-month EBITDA of $690.5 million. Such leverage raises refinancing risk and potential credit downgrades. Though Sunrun posted positive free cash flow in the latest quarter, the long-term trend of cash incineration persists. The stock trades at a forward price-to-earnings multiple of 30.5 times, which analysts view as unattractive given the fundamental concerns.
