The Fundamentalytics view

Next results ~November 3, 2026 (estimated)

Otter Tail Corp's trailing-twelve-month revenue fell 0.2% year on year, with a free-cash-flow margin of -6.1%. Where it stands out: change in share count of -0.0% ranks 2 of 23 electric utilities companies we cover. Where it lags: revenue growth of -0.2% ranks 25 of 25 electric utilities companies we cover.

Our discounted-cash-flow model values the business at ~$5.2 per share in the base case (—–$14 across growth scenarios) — model values under stated assumptions, not a price target.

Current signal Capital expenditure surging: TTM capex grew 59% year over year and now absorbs 37.4% of revenue.

Valuation

Otter Tail Corp valuation models and calculator

Fundamentalytics rating

model v1.6 · 2026-11-03

Not rated: held for review: our cash-flow value ($5.19) was left out of our combined valuation (it is 0.06x the share price, outside the 0.2-5x range we accept), so it can't be the basis of a rating.

Our value per share comes from a discounted-cash-flow model of Otter Tail Corp's free cash flow after stock-based pay ( $69.3M, 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.

The inputs used by the models below have passed source checks. Individual model values are available below and in the interactive valuator. Their differences are shown explicitly; the platform combined value and recommendation remain withheld.

Valuation models

We value Otter Tail Corp as an utility or power producer, with every model that fits that kind of business. Cost of equity 7.4%: the 10-year Treasury yield (4.9%) plus a beta of 0.54 times a 4.5% equity risk premium.

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. ~$5.2 Left out: out of range vs price (0.06x)
Utility earnings model Net income growing 3% a year, discounted at 8%: for regulated investment that makes free cash flow negative. ~$96 ~$79–$120 Included

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Otter Tail Corp with utilities and power producers in our coverage, using third-party market data.

Moat

57 /100

Moderate moat

How hard Otter Tail's competitive advantage looks for rivals to wear away, judged from 10 years of its own filings: returns on capital, pricing power, profit durability, cash conversion and discipline.

  • Returns on capital 5 / 20

    Net income has been a median 4.6% of total assets over 10 years.

  • Durability 15 / 20

    Operating margin has been a median 17.8%; its worst year was 13.9%.

  • Cash conversion 9 / 20

    Free cash flow was positive in 7 of 10 years, at a median 4.5% of revenue.

  • Discipline 16 / 20

    The diluted share count rose 1.4% over five years; stock-based pay has been a median 0.6% of revenue.

AI disruption exposure: Low. In this industry, the business rests on physical assets, regulated networks or products AI itself depends on.
