Our note on each quarter Tantech Holdings files

Where Tantech stands after its latest Filing

Revenue for the twelve months was $38m, down 10.7% on a year earlier, a steeper fall than the 3.8% decline a quarter earlier. That puts it 35 of 42 for growth among the specialty chemicals companies we cover. Free-cash-flow margin held at -15.2%. Operating margin narrowed to -31.8% from -15.4%. The diluted share count is up 444.4% on a year earlier, which dilutes existing holders. Against its peers on growth, profitability, cash generation and balance sheet, it grades E. It passes 2 of our 3 financial-health checks. Our cash-flow model value is $27.66 a share, against a share price of $12.28.

The Fundamentalytics view

Tantech Holdings LTD's trailing-twelve-month revenue fell 10.7% year on year, with a free-cash-flow margin of -15.2%. Where it stands out: long-term debt as % of assets of 0.1% ranks 3 of 36 specialty chemicals companies we cover. Where it lags: days sales outstanding of 264 days ranks 30 of 30 specialty chemicals companies we cover.

Our discounted-cash-flow model values the business at ~$28 per share in the base case (~$24–$32 across growth scenarios) — model values under stated assumptions, not a price target.

Current signal Share count rising (dilution): Diluted shares outstanding rose 444.4% year over year.

Valuation

Tantech Holdings LTD valuation models and calculator

What the price is pricing in

The share price implies cash flow shrinking more than 30% a year in our model.

  • Last 12 months-10.7%
  • 3 years a year-10.2%
  • 5 years a year-1.9%

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 ($12.19, 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. This is a model exercise, not investment advice or a forecast of the share price. All companies

How we got here: a discounted-cash-flow model of Tantech Holdings LTD's free cash flow after stock-based pay with after-tax interest added back ($1.6M, FY2025 Q4 TTM), growing 4% a year for five years and fading to 2.5%, discounted at 8.5%. Lower and higher growth cases span ~$24–~$32 ; 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 Tantech Holdings LTD's free cash flow after stock-based pay ( $1.6M, FY2025 Q4 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 Tantech Holdings LTD as an operating company, with every model that fits that kind of business. Cost of equity 8.4%: the 10-year Treasury yield (4.9%) plus a beta of 0.78 times a 4.5% equity risk premium.
