AI Analysis

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

Acorn Energy is a $45.5 million market-cap technology company with 26 employees, selling wireless remote monitoring and control systems through power generation and cathodic protection segments. That is a narrow, specialized business, and the filed figures show a bumpy record: fiscal 2023 revenue was $8.1 million with $119,000 net income; fiscal 2024 revenue was $11.0 million with $6.3 million net income; fiscal 2025 revenue was $11.5 million with $2.5 million net income. Profit fell sharply in fiscal 2025 despite slightly higher revenue, and the most recent quarter, fiscal Q2 2026 ended 2026-06-30, showed revenue of $2.5 million and net income of $294,000, down from fiscal Q2 2025 revenue of $3.5 million and net income of $720,000. FairStock lists revenue growth of -32.64% and profit growth of -79.48%. The balance sheet has low debt—D/E 0.11—and Piotroski F-Score 7/9, but Altman Z-Score is -3.00, which warns of financial fragility. Returns are mixed: ROE 19.87% but ROCE only 3.30%, suggesting the equity return may not reflect strong operating capital efficiency. Free cash flow is just $1.2 million, a 2.6% FCF yield. At the 2026-10-13 close of $18.15, FairStock’s P/E is 29.75, P/B 5.19, EV/EBITDA 51.57, and Graham Number $6.93, leaving a margin of safety of -161.90%. In Graham terms, I want to buy well below intrinsic value; here the price is well above several value anchors. The Lynch category is TURNAROUND—returned to profit after a loss within the last three years—but turnarounds require improving sales and durable earnings, and this one is not yet showing that. I would wait for evidence of stable revenue and stronger cash generation before calling it a bargain.

In plain English: Acorn Energy makes wireless monitoring and control equipment, mainly for power generators and industrial protection. The business is very small and recently profitable, but sales and profits have fallen from a year earlier. At $18.15, the stock price looks high compared with the company's recent profits and cash flow.
