Value Olin yourself

Olin's revenue rose 3.7% to $6.8 billion in fiscal 2025. Its operating margin was 0.1%, down from 4.5% a year earlier. Free cash flow was $248 million, down 19.5%. It paid out $142 million in dividends and buybacks, 57% of free cash flow. The diluted share count fell 4.1%.

Operating margin is operating income as a share of revenue. Free cash flow is cash from operations minus capital spending. Return on capital is after-tax operating income as a share of the money invested in the business: debt plus equity, minus cash. Market cap is the last closing share price times the latest diluted share count, so it is approximate. P/E is the last close divided by diluted earnings per share over the last four quarters, or the latest fiscal year where the quarters aren't available; there is none when the company made a loss.

Net income and earnings per share

From fiscal 2017 to 2024, earnings per share fell 16.7% a year and net income 21.1% a year, while buybacks cut the share count by 29%. Olin then lost money in fiscal 2025.

Valuation

Two ways to value Olin yourself, both starting from its filings: a discounted cash flow model and the price-to-earnings method.

Discounted cash flow (DCF)

A discounted cash flow (DCF) model values a business as the cash it may generate in future, discounted back to today. The starting figures come from Olin's 10-K (or, for net cash and shares, its latest 10-Q) and the assumptions are yours: start from one of three example scenarios, then change any figure to see what it implies for a share, and how that compares with the last share price.

Value per share on three example scenarios, from Olin's fiscal 2025 free cash flow of $248M, net cash of −$2.7B at December 31, 2025 and 115 million diluted shares, from its filings. The scenarios are fitted to Olin: the base scenario's growth in years 1 to 5 is its revenue growth over the last 3 years, -10.2% a year, kept between 0% and 20%; the cautious and optimistic ones are lower and higher, and growth in years 6 to 10 is halfway to the long-run rate. The base scenario's discount rate is 13%: 11% for a cyclical or higher-risk business (Diversified Chemicals), plus 1 point as a smaller company, worth $1.8B, plus 1 point for unsteady results (a loss in fiscal 2025); the cautious and optimistic ones use a point more and a point less. Select one to load it into the calculator. These are the model's arithmetic on those assumptions, not a forecast or a price target. A negative value means Olin's net debt is larger than what that scenario's cash flows are worth today.

From the filings
Cash from operations minus capital spending in fiscal 2025.
Cash and short-term investments minus debt and finance leases at December 31, 2025. Negative means net debt.
Weighted-average diluted shares in fiscal 2025.
Your assumptions
Start from
Fitted to Olin's own revenue growth, as above. Cautious: growth of -2% then 0% a year, 2% after year 10, a 14% discount rate. Base: growth of 0% then 1% a year, 2.5% after year 10, a 13% discount rate. Optimistic: growth of 2% then 2.5% a year, 3% after year 10, a 12% discount rate.
Long-run growth forever after year 10. Usually close to inflation, and always below the discount rate.
The yearly return an investor wants for the risk. A higher rate gives a lower value.

How the value changes with two assumptions

Value per share in US$, with the growth rates above. The highlighted cell matches the current assumptions.
How the model works. Free cash flow grows at the first rate for five years and the second rate for five more, and each year is discounted at the discount rate. Everything after year 10 is valued as year-10 cash flow × (1 + growth after year 10) ÷ (discount rate − growth after year 10), discounted back ten years. Net cash is added and the total is divided by diluted shares. The result depends entirely on the assumptions. It is not a forecast, a price target or a recommendation. The last close is the consolidated US closing price, from Databento.

Price-to-earnings (P/E) method

Another common way to value a company is to multiply its earnings per share by a price-to-earnings (P/E) multiple: the number of years of today's earnings an investor pays for a share. A higher multiple usually means investors expect earnings to grow. Choose a multiple, for example from similar companies, to see the value it gives.

The P/E method needs positive earnings, and Olin's latest diluted earnings per share were negative or zero.

US$ millions unless stated, at each fiscal year end. Net debt to EBITDA is debt minus cash, divided by operating income before depreciation and amortization: roughly how many years of those earnings the net debt equals. Debt to equity is debt as a multiple of shareholders' equity. Interest coverage is operating income divided by interest expense. The current ratio is current assets over current liabilities; the quick ratio leaves out inventory.

Grants, option exercises and shares withheld for tax aren't counted. Insiders buy and sell for many reasons, such as taxes, spreading their savings or a plan set up months earlier, so a trade on its own says little about where a company is heading.

Piotroski F-score

The F-score counts how many of nine simple tests of profitability, funding and efficiency a company passed in a year (Piotroski, 2000). The more tests passed, the stronger the year: 8 or 9 is strong, 0 to 2 weak. Companies that report no gross profit are scored on the other eight.
