Our note on each quarter Acorn Energy files

Where Acorn Energy stands after its latest 10-Q

Revenue for the twelve months to June 2026 was $10m, down 27.5% on a year earlier, a steeper fall than the 11.3% decline a quarter earlier. That puts it 22 of 22 for growth among the research & consulting services companies we cover. Free-cash-flow margin rose to 15.3% from 13.4% a year earlier. Operating margin narrowed to 7.1% from 23.9%. Against its peers on growth, profitability, cash generation and balance sheet, it grades C. It passes 2 of our 2 financial-health checks. Our cash-flow model value is $7.71 a share, against a share price of $17.78. At that price, our model says the market is pricing in about 21.8% a year of cash-flow growth for five years, faster than the 7.2% a year revenue growth it has delivered.

Valuation

Acorn Energy, Inc. valuation models and calculator

What the price is pricing in

The share price implies about 20.4% a year of cash-flow growth for five years.That is faster than the 7.2% a year revenue growth Acorn Energy has delivered.

  • Priced in20.4%
  • Last 12 months-27.5%
  • 3 years a year9.2%
  • 5 years a year7.2%

Our cash-flow model with every input fixed except growth over the next five years, solved for the growth at which the model value equals the share price ($16.80, Nov 3, 2026). Cash-flow growth then fades to 2.5% a year; discount rate 8.5%. Delivered figures are revenue growth from SEC filings.

How we got here: a discounted-cash-flow model of Acorn Energy, Inc.'s free cash flow after stock-based pay with after-tax interest added back ($814,766, FY2026 Q2 TTM), growing 4% a year for five years and fading to 2.5%, discounted at 8.5%. Lower and higher growth cases span ~$6.3–~$9.8 ; that spread sets a 15% margin before we rate Buy or Sell.

Produced by Fundamentalytics' automated valuation model on November 3, 2026, using delayed market prices. Rating meanings, methodology and conflicts: recommendations disclosure and research disclaimer. General research, not personal advice — it does not consider your circumstances. Prices can fall as well as rise.

Our value per share comes from a discounted-cash-flow model of Acorn Energy, Inc.'s free cash flow after stock-based pay ( $814,766, FY2026 Q2 TTM, with after-tax interest added back): growth for five years as below (the first two years from forecasts, guidance and the company's record), fading to 2.5%, discounted at 8.5%, then cash added and debt and other claims subtracted. These are model values under stated assumptions, not price targets or recommendations.

Valuation models

We value Acorn Energy, Inc. as an operating company, with every model that fits that kind of business. Cost of equity 9.1%: the 10-year Treasury yield (4.9%) plus a beta of 0.92 times a 4.5% equity risk premium.

Value per share by model
Model Value per share In the combined value?
Cash-flow model (DCF) Free cash flow to the firm (after stock pay, with after-tax interest added back), grown then faded to 2.5%, discounted at 8.5% as the firm rate, less debt and other claims. ~$7.8 ~$6.3–$9.8 Primary model, counts double
Price-to-earnings vs peers Earnings per share times peers' typical (harmonic-mean) price-to-earnings. ~$12 ~$12–$18 Included
Residual income Book value plus the present value of returns above the cost of equity, fading over ten years. — Does not apply: return on equity above 40%: buybacks or intangibles make book value too small an anchor
Justified price-to-book Book value times (return on equity - growth) / (cost of equity - growth): steady-state returns. ~$11 ~$9.0–$13 Included
Combined value Weighted average of the models that apply: the primary model (cash-flow model (dcf)) counts double. Models more than 5x or less than 0.2x the share price, or more than 3x away from the other models' median, are left out. ~$9.7 ~$7.8–$12 3 models

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Acorn Energy, Inc. with Research & Consulting Services in our coverage, using third-party market data.

Free cash flow is cash from operations minus capital spending. Growth is left blank when last year's figure was a loss or under 2% of revenue. Share counts and EPS are restated for stock splits. A dash means the company didn't report the figure.
