A share price tends to move through four phases: moving sideways (stage 1), rising (stage 2), stalling near a high (stage 3) and falling (stage 4). Today Koppers Holdings Inc. is in stage 2. The phase helps read everything below.

Over the past 13 weeks it has done worse than the S&P 500, and it has been behind for 7 weeks running.

This page treats a rise as over when the price closes below its 200-day average on two Fridays in a row.

Koppers Holdings Inc. paid $0.34 per share over the last four reported quarters. The most recent declaration was $0.09 for Jun 2026. At today's price of $42.89 that is a yield of 0.79%, based on dividends already paid, not a forecast.

A dividend is cash paid out for each share. The 12-month total is the four most recent quarters added together.

Koppers Holdings is not in the Nasdaq 100, the S&P 500 or the Dow Jones 30, and is not on the US tech stocks list.

Koppers Holdings Inc. posted a net loss of $148 M in the Jun 2026 quarter. Full-year FY25 profit was $56.0 M. Over 4 years profit has grown −9.9% a year on average. That loss is 28.4% of the quarter's revenue. The same quarter a year earlier earned $16.4 M. 3 of the last 12 reported quarters were loss-making.

Net profit is what is left after every cost, interest and tax. Earnings per share, dividends and book value all grow from it.

Jun 2026 profit was −$148 M, −999.4% on a year earlier. For the full year, FY25 profit was $56.0 M (+15.2% on the year before).

Koppers Holdings Inc. reported $520 M of revenue in the Jun 2026 quarter, +3.0% on the same quarter a year earlier. Over 4 years it has grown 2.9% a year on average. The last full year, FY25, came in at $1.9 B. The last four reported quarters add to $1.9 B.

Revenue is everything the company billed its customers in the period.

FY25 revenue was $1.9 B, −10.2% on the year before.

Recent pace: the last four quarters grew −4.8% on average, against 2.9% a year over the longer run, so this year is growing slower than its own long-run rate.

Is growth speeding up? Revenue over the last 12 months grew −5.0%, against −5.6% a year over the last 8 quarters (stabilising).

Koppers Holdings Inc.'s operating margin was 9.7% in the Jun 2026 quarter, 1.5 percentage points lower than the same quarter a year ago. Its latest full-year margin is the highest it has ever reported. Across 5 years it has been between 6.8% and 11.6%. The latest quarter is within that range.

Operating margin is what is left from every $100 of sales after the costs of running the business, before interest and tax. It shows pricing power and cost control.

Across 5 years it has been between 6.8% and 11.6%, and FY25's 11.6% is the highest of them.

Why the margin moved: operating margin changed −1.5 percentage points on the year while gross margin changed −1.6 points. So the drop came mostly from the gross margin, which means input costs and prices charged.

When margins are at a record, every ratio built on profit looks better than usual, so watch whether they hold.

Over the last 3 years, 200% of Koppers Holdings Inc.'s reported profit came in as cash from its operations, so the profit is backed by cash. In FY25 it brought in $123 M of operating cash against $56.0 M of profit. After $55.0 M of spending on assets, $67.5 M was left over as free cash.

The profit and loss account shows what was earned. The cash-flow statement shows the cash that actually came in. Comparing operating cash flow with profit is one of the best checks that a profit is real.

Cash-flow figures here are yearly, because quarterly cash statements are not published, so this section changes once a year.

Why: the cash figure is clear, but the day counts behind it are not in our data, so we show it without guessing the reason.

What to look at next: the main use of cash is spending on assets. The next section checks what that spending is building.

Koppers Holdings Inc. does not report the customer, stock and supplier day counts a cash cycle needs, so this section looks at its spending on assets instead. It spent $253 M on assets over the last 3 years. Averaged over those years that is 4.5% of FY25 revenue a year.

Working capital is the cash tied up between paying suppliers and getting paid. Debtor days: how long customers take to pay. Inventory days: how long stock sits. The cash cycle: the whole loop, in days of sales.

Nothing is estimated in place of the missing day counts, so no cash-cycle chart is drawn.

Spending on assets: $253 M over the last 3 years.

In short: the cash is going into new capacity, not getting stuck in the daily cycle. The question is whether the new capacity earns.

Koppers Holdings Inc.'s P/E is 13.5×, with too little history to compare. This compares the share price with the company’s own past. It does not say what the business is worth.

P/E is the share price divided by a year's profit per share: how many dollars the market pays for each dollar of yearly profit.

Why the multiple is where it is: over the past year earnings per share moved +11.4% while the price moved +60.6%. The price did better than earnings, which pushed the multiple up within its own range.

Where the price move came from: over 3 years the price moved +4.2% a year; about −3.4% a year came from earnings growth and about +7.6 percentage points from the multiple (the market paying more). The split is approximate (price return minus earnings growth). It shows how much of the move came from the market paying a different multiple.

In short: there is too little history to say whether the multiple is high or low for this company, so the earnings trend underneath matters more than the multiple.

Koppers Holdings Inc.'s business is giving mixed signals. Revenue growth is rising from its low at −5.0% while eps growth is falling at −764.2%, so the lines disagree and each one tells part of the story. This is based on 12 quarters of 4 measures.

Every business is somewhere on a path of getting better or worse, and this section names where. The last 12 quarters of growth in revenue, profit and earnings per share, plus the return the business earns on its capital, are read as lines. Getting worse: the lines are falling. Turning around: a low point has just formed and the last few quarters are rising from it. Getting better: the rise from the low has lasted. Growing steadily: steady growth with healthy returns. Slowing from a peak: still high, but slowing. When the lines disagree the result is mixed; too little history means no reading. CAGR (compound annual growth rate) is the steady yearly rate that would turn the starting value into the latest one. It is the fairest way to compare growth over different periods. If the 1-year figure is much bigger than the 10-year one, recent growth is running faster than the long-run trend. A dash means there is no figure for that period, or the starting year was a loss, where a growth rate means nothing.

Why it matters: when the lines disagree, each line above matters more than any single label.

The latest quarter’s profit includes a one-off item bigger than the normal business, so the profit line is shown but does not count in this reading.

Compound annual growth rate (%)

Compound annual growth rate over each period, %. Revenue, profit and EPS come from yearly figures; the stock price row is price growth over the same periods. A dash means no figure for that period, or the starting year was a loss.

Koppers Holdings Inc. earned a ROE of 10% in FY25. Its return on capital used (ROIC) is 5.6 percentage points above its cost of capital, so growth here adds value, not just size. It comes from a 3.0% net margin and 1.00× asset turnover (sales divided by assets).

Return on equity (ROE) is the profit the business earns on its shareholders’ money. We do not have the full capital split, so ROE is the longest history we can draw here.

Why the return is what it is (FY25): a 3.0% net margin × 1.00× asset turnover × 3.29× leverage (assets divided by equity) ≈ 9.9% on equity. The margin does its share; borrowing is a big part of it.

The key test, return on capital used minus the cost of capital: 13.2% − 7.6% = +5.6 percentage points. The 7.6% is an estimate of this company's own cost of capital. Read the sign and size of the gap, not the decimals. A gap this wide means each dollar put back into the business creates more than a dollar of value.

The 13.2% ROIC above is the latest reading, as reported. The yearly chart below shows FY25 at 9.9%, and the quarterly chart works out each 12-month window from the quarterly figures, so the readings differ by date, not by method.
