Where Olin stands after its latest 10-Q

Revenue for the twelve months to June 2026 was $6.70bn, up 0.6% on a year earlier, slower than 2.6% a quarter earlier. That puts it 808 of 931 for growth among all the companies we cover. Free-cash-flow margin fell to 1.5% from 4.1% a year earlier. Operating margin narrowed to -1.6% from 2.1%. The diluted share count is down 2.7% on a year earlier, which lifts each remaining share. Against its peers on growth, profitability, cash generation and balance sheet, it grades D. It passes 1 of our 7 financial-health checks. Our cash-flow model value is $37.12 a share, against a share price of $15.12. At that price, our model says the market is pricing in cash flow shrinking about 5.5% a year for five years, close to the -5.5% a year revenue growth it has delivered.

Olin Corp's trailing-twelve-month revenue fell 0.7% year on year, with a free-cash-flow margin of 3.3%. Where it stands out: change in share count of -2.4% ranks 2 of 12 commodity chemicals companies we cover.

Our discounted-cash-flow model values the business at ~$59 per share in the base case (~$38–$88 across growth scenarios) — model values under stated assumptions, not a price target.

Valuation

Olin Corp valuation models and calculator

What the price is pricing in

The share price implies cash flow shrinking about 8.9% a year for five years.That is close to the -5.4% a year revenue growth Olin has delivered.

Read with care: free cash flow has swung sharply in the past year (often a one-off tax, legal or working-capital item), so the cash-flow base behind this reading may be unusually low or high.

  • Priced in-8.9%
  • Last 12 months-0.7%
  • 3 years a year-2.2%
  • 5 years a year-5.4%

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 ($17.71, 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 Olin Corp's free cash flow after stock-based pay with after-tax interest added back ($565M, FY2026 Q3 TTM), growing 4.5% and 2.7% in the next two years (forecasts, guidance and its record), then back to 2% by year five, and fading to 2.5%, discounted at 8.5%. Lower and higher growth cases span ~$38–~$88 ; that spread sets a 35% 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 Olin Corp's free cash flow after stock-based pay ( $565M, FY2026 Q3 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 Olin Corp as an operating company, with every model that fits that kind of business. Cost of equity 9.3%: the 10-year Treasury yield (4.9%) plus a beta of 0.97 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. ~$59 ~$38–$88 Primary model, counts double
Forward price-to-earnings vs peers Next year's consensus earnings per share times peers' typical (harmonic-mean) forward price-to-earnings. Uses analysts' consensus estimates (third-party data), not our forecasts. ~$5.4 ~$4.0–$8.3 Left out: far from the other models (more than 3x away from their median)
Residual income Book value plus the present value of returns above the cost of equity, fading over ten years. ~$31 ~$22–$43 Included
Justified price-to-book Book value times (return on equity - growth) / (cost of equity - growth): steady-state returns. ~$31 ~$27–$37 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. ~$45 ~$31–$59 3 models

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Olin Corp with Commodity Chemicals in our coverage, using third-party market data.

Moat

Weak moat

How hard Olin'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 0 / 20

    Net income has been a median 1.6% of total assets over 10 years.

  • Durability 0 / 20

    Operating margin has been a median 5.5%; its worst year was -16.0%.

  • Cash conversion 14 / 20

    Free cash flow was positive in 10 of 10 years, at a median 7.2% of revenue.

  • Discipline 20 / 20

    The diluted share count fell 29.7% over five years; stock-based pay has been a median 0.3% of revenue.

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

Options strategies

All options ideas

How Olin Corp’s listed options are priced, and three ways to use them that follow from our valuation. Quotes are delayed, read November 2, 2026. Check the live chain at your broker before trading.

Cash-secured put

Not offered: fundamentals grade C+ (needs B+ or better).

We suggest selling a put only on well-rated companies, at a strike where the price you would pay if assigned (strike less premium) is at or below our fair value.

Covered call

Not offered: no liquid call at or above our price target — the model says the upside is worth more than any listed strike.

For holders: sell a call at a strike at or above our fair value, so the shares are only sold at a price the model calls full value.

Collar

Not offered: the shares trade below our fair value: a collar caps upside the model expects.

For holders of a stock trading at or above our fair value: buy a put for a floor and sell a call to pay for it.

General research, not personal advice. Options can lose you more than you expect and are not suitable for everyone: put sellers can be made to buy shares that keep falling, call sellers give up gains above the strike, and results or news can move prices sharply. Chances shown are approximations from each option’s delta. Spreads, fees and early assignment are not modelled.
