AI Analysis

AI-generated, general educational analysis — not personal investment advice.

Sunrun is a residential solar and battery business with a capital-intensive model, and it does not look like a classic Buffett moat. The recent filed numbers show improvement: in fiscal Q2 2026, the quarter ended 2026-06-30, revenue was $870.0M and net income was $115.2M, or diluted EPS $0.42; in fiscal Q1 2026, the quarter ended 2026-03-31, revenue was $722.2M and net income was $167.6M, or $0.62 per diluted share. In fiscal year 2025, the year ended 2025-12-31, revenue was $3.0B and net income was $449.9M, or $1.71 per diluted share, a sharp reversal from fiscal year 2024, the year ended 2024-12-31, when revenue was $2.0B and net income was $-2.8B. FairStock classifies it as TURNAROUND because it returned to profit after a loss within the last three years. Yet Graham would focus on the balance sheet and cash. The trailing twelve-month free cash flow is $-2.2B and the FairStock FCF yield is -117.9%, while debt-to-equity is 2.93 and the FairStock Altman Z-score is -0.08, both warning signs. FairStock's ROE is -19.86% and ROCE is 0.26%. At the $7.79 close on 2026-10-13, FairStock's P/E is 5.30 and P/B is 0.54; its Graham Number is $21.92, implying a 64.46% margin of safety. That looks statistically cheap, but negative cash flow and a negative Z-score suggest the earnings may not be durable. The FairStock Piotroski F-score of 4/9 confirms mixed quality. I would want evidence that profits convert to cash and that leverage falls before trusting the optical cheapness.

In plain English: Sunrun installs and maintains home solar and battery systems for homeowners. It has recently made money after losses, and sales have been growing, but it still uses more cash than it brings in and carries a lot of debt, so the business looks fragile. At $7.79, the shares look low compared with recent profits and accounting value, though the cash drain makes that cheapness uncertain.
