Fun facts about Koppers Holdings Inc.

Quirks, history, and lore behind KOP — the kind of stuff that makes a stock memorable.

1
The Basics
U.S. industrials company · small-cap · listed on the NYSE · headquartered in Pittsburgh, Pennsylvania.
2
The Numbers
Annual revenue in the range of roughly $2 billion, with operations spread across North America, Europe, and Australia — a surprisingly global footprint for a company most people have never heard of.

It is one of the world's leading producers of carbon compounds and treated wood products — the stuff that keeps railroad ties in the ground and utility poles standing up.
5
The Lore
The company's carbon black and creosote products are unglamorous but essential: without them, railways would rot and tires would fall apart faster than a bad earnings call.
6

AI Insight: KOP Financial Trends

Debt reduction is the clearest bright spot — total debt fell $72M over four quarters to $933M in Q4 2025 — but Q1 2026 shows renewed margin pressure with op income collapsing to $22M.

• Total debt declined from $1,006M in Q2 2024 to $933M in Q4 2025, a $73M reduction over six quarters.

• Operating income recovered from a trough of $6M in Q4 2024 to $52M in Q3 2025, before dropping sharply to $22M in Q1 2026.

• Revenue has trended downward from $563M in Q2 2024 to $455M in Q1 2026, a roughly 19% decline over the period.

• Operating cash flow improved meaningfully, turning from -$23M in Q1 2025 to $46M in Q1 2026, the same quarter a year later.

⚠ Op income fell from $50M in Q4 2025 to $22M in Q1 2026 — steepest sequential drop since Q3–Q4 2024 deterioration.

⚠ Net income dropped to $7M in Q1 2026 from $30M in Q4 2025, reversing a three-quarter recovery trend.

⚠ Total debt ticked up slightly to $934M in Q1 2026 after reaching a low of $933M in Q4 2025 — watch whether deleveraging stalls.

AI Insight: KOP Ratio Trends

KOP's profitability recovery through Q4 2025 stalled sharply in Q1 2026, with ROIC collapsing to 5.9% from 13.2% the prior quarter.

• Operating margin recovered from a trough of 1.3% in Q4 2024 to 11.5% in Q4 2025, then fell back to 4.8% in Q1 2026.

• Leverage has improved modestly: D/E declined from 2.00 in Q1 2025 to 1.63 in Q4 2025, edging back up to 1.70 in Q1 2026.

• Net profit margin swung from -3.0% in Q1 2025 to 6.9% in Q4 2025, then dropped to 1.6% in Q1 2026.

⚠ Q1 2026 ROIC of 5.9% mirrors the weak Q1 2025 reading of 7.2% — seasonal or structural Q1 weakness warrants monitoring.

⚠ ROE fell to 5.2% in Q1 2026 from 20.7% in Q4 2025 — steepest single-quarter drop since Q4 2024's loss quarter.

⚠ D/E ticking back up to 1.70 in Q1 2026 after reaching 1.63 in Q4 2025 — deleveraging progress may be stalling.
