Revenue for the twelve months to June 2026 was $1.89bn, down 5.0% on a year earlier, a smaller fall than the 8.4% decline a quarter earlier. That puts it 11 of 11 for growth among the commodity chemicals companies we cover. Free-cash-flow margin rose to 7.3% from 3.6% a year earlier. Operating margin narrowed to -2.2% from 6.1%. The diluted share count is down 2.5% on a year earlier, which lifts each remaining share. Against its peers on growth, profitability, cash generation and balance sheet, it grades C+. It passes 2 of our 7 financial-health checks.

Where it stands out: change in share count of -2.5% ranks 1 of 12 commodity chemicals companies we cover.

Highlights

How we pick these

Strengths

  • Shrinking share count. Diluted shares fell 2.5% in a year, so each share owns more of the business.
  • Beating expectations. Earnings per share beat the analysts' consensus estimate in each of the last four quarters.

Things to watch

  • Results due soon. Results are expected around 6 November; the share price can move sharply on the day.
  • Revenue shrinking. Revenue fell 5.0% over the last 12 months.
  • Loss-making. Operating margin is -2.2%: costs exceed revenue.
  • Margins narrowing. Operating margin is down 8.4 points on a year ago.
  • Below peers: long-term debt as % of assets. Long-term debt as % of assets of 51.8% ranks 10 of 12 commodity chemicals companies we cover (median 37.2%).
  • Below peers: stock pay as % of revenue. Stock pay as % of revenue of 0.6% ranks 8 of 10 commodity chemicals companies we cover (median 0.4%).

Moat

53 /100

Moderate moat

How hard Koppers'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 16 / 20

    Cash operating profit has been a median 12.6% of total assets over 10 years.

  • Pricing power 8 / 20

    Gross margin has been a median 21.5%, moving by 2.2 percentage points (standard deviation) across 10 years.

  • Durability 1 / 20

    Operating margin has been a median 7.6%; its worst year was -2.2%.

  • Cash conversion 8 / 20

    Free cash flow was positive in 7 of 10 years, at a median 2.6% of revenue.

  • Discipline 19 / 20

    The diluted share count fell 7.7% over five years; stock-based pay has been a median 0.7% of revenue.

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