Koppers Cuts 2026 Adjusted EBITDA Guide to $220-225M

Koppers Holdings Inc. (NYSE: KOP) reported third-quarter 2026 net sales of $499.1 million and net income of $14.7 million, or $0.75 per diluted share, the Pittsburgh-based treated wood and carbon compounds maker announced on 6 November 2026. Adjusted EBITDA fell to $58.0 million from $70.9 million a year earlier, and the company lowered its full-year 2026 adjusted EBITDA forecast to a $220-225 million range from a prior $240-250 million range. Adjusted EPS guidance dropped to $3.10-$3.25 from $3.80-$4.20.

Context — Why Koppers Cut Its 2026 Profit Outlook

The revision lands against a prior forecast the company issued earlier in 2026, when it still expected adjusted EBITDA of $240-250 million and net sales of $1.9-2.0 billion. Koppers now expects net sales of roughly $1.9 billion, the low end of that earlier range, and 2025 actuals of $257 million adjusted EBITDA and $4.07 adjusted EPS frame the size of the downgrade.

Management tied the miss to input costs rather than demand. "Higher raw material and logistics costs are more than offsetting those benefits in the near term," Chief Executive Officer and Chair Leroy Ball said, referring to volume growth and cost actions.

Koppers operates three segments: Railroad and Utility Products and Services, or RUPS, which supplies crossties and utility poles; Performance Chemicals, which makes wood preservatives; and Carbon Materials and Chemicals, or CMC, which sells carbon pitch and carbon black feedstock. Each faces a different cost curve, and the third quarter showed the divergence clearly.

The timing matters because Koppers sells into infrastructure and industrial end markets where contract pricing resets slowly. When scrap copper, energy and freight costs spike mid-year, the company absorbs the gap until commercial terms roll over. Ball said commercial actions taking effect in 2027 will help reset earnings to a meaningfully higher level.

Broader industrial cost pressure has been a theme across materials producers in 2026, though the report does not name peer results. Koppers frames its own fix through the Catalyst transformation program, an internal initiative aimed at changing how the company drives performance improvement.

Data — What Koppers' Q3 2026 Numbers Show

Segment results explain where the $12.9 million adjusted EBITDA decline came from. Performance Chemicals was the only unit to grow profitability, while RUPS and CMC both contracted.

Segment	Q3 2026 Adj. EBITDA	Q3 2025 Adj. EBITDA	Change
Railroad and Utility Products and Services	$22.3M	$29.2M	-23.6%
Performance Chemicals	$29.6M	$26.1M	+13.4%
Carbon Materials and Chemicals	$6.1M	$15.6M	-60.9%
Total	$58.0M	$70.9M	-18.2%

Net sales rose 2.8 percent to $499.1 million, helped by a $6.1 million favorable currency effect. Performance Chemicals sales climbed 11.9 percent to $161.5 million on ten percent volume growth, mainly in the Americas, driven by market share gains and inventory restocking.

CMC sales fell 3.2 percent to $104.8 million. Carbon pitch prices were roughly four percent higher globally, but volumes dropped, and adjusted EBITDA absorbed $9.0 million of higher raw material costs plus $1.7 million of lower utilization tied to feedstock quality issues and the accelerated closure of the Stickney facility.

RUPS sales were flat at $232.8 million. Crosstie price declines, particularly for Class I, and roughly $6.3 million lost from a railroad services business sold in the third quarter of 2025 offset volume gains, including a five percent rise in domestic utility pole volumes.

Cash generation ran counter to earnings. Operating cash flow for the nine months ended 30 September 2026 hit a record $126.9 million versus $77.4 million a year earlier, and free cash flow reached $92.0 million against $39.0 million. Koppers returned $56.2 million to shareholders and cut total debt by $31.0 million, or net debt by $35.8 million, year to date.

Analysis — What the Guidance Cut Means for KOP and Industrials

The split between falling profit and record cash flow is the central tension in this report. Koppers held its operating cash flow guidance at $165-185 million and raised free cash flow guidance to $115-135 million from $110-130 million, even while cutting adjusted EBITDA by roughly $20 million at the midpoint. That implies working capital, not earnings, is carrying the cash story.

The margin math is unforgiving. Adjusted EBITDA margin at CMC fell to 5.8 percent from 14.4 percent, a 8.6 percentage point drop, while RUPS slipped to 9.6 percent from 12.5 percent. Only Performance Chemicals held steady near 18 percent. A company that historically earned mid-teens margins at CMC now earns low single digits there, which pressures the blended multiple investors apply to KOP.

Counter-argument: the accelerated Stickney closure and the idling of the Florence treating plant are self-help actions that remove cost from the network. If those savings land as planned, 2027 could show a step-change in margins that the current quarter does not capture. The risk is that raw material and logistics inflation persists past the point where commercial price increases catch up.

Positioning follows the cash. Investors screening for free cash flow yield may find KOP more attractive than the headline earnings decline suggests, while earnings-focused funds may stay on the sidelines until segment margins stabilize. The company did not disclose the terms of the railroad services business sale or the size of expected 2027 commercial actions.

Outlook — What to Watch for Koppers in 2027

The company's updated 2026 forecast is the near-term benchmark: net sales around $1.9 billion, adjusted EBITDA of $220-225 million, adjusted EPS of $3.10-$3.25, an effective tax rate of 31 percent on adjusted net income, capital expenditures of $50 million, operating cash flow of $165-185 million and free cash flow of $115-135 million. The prior forecast had assumed a 28 percent tax rate and $55 million of capex.

Koppers does not provide reconciliations of its adjusted EBITDA, free cash flow or adjusted EPS guidance to comparable GAAP measures, citing the unreasonable efforts exception. Items it cannot forecast include restructuring and impairment charges, acquisition-related costs, mark-to-market commodity hedging and LIFO adjustments.

Watch the fourth-quarter report for evidence that raw material and logistics costs are moderating, and for any detail on the 2027 commercial actions Ball referenced. The nine-month impairment and restructuring line of $233.4 million, versus $47.8 million a year earlier, also warrants attention, since it reflects the production network changes now underway.

Frequently Asked Questions

Why did Koppers cut its 2026 adjusted EBITDA guidance?

Koppers said higher raw material and logistics costs, partly influenced by elevated energy prices, created margin pressure expected to persist through the remainder of 2026. The company also cited weaker end market demand and noted that planned production network optimization would not fully offset those headwinds in the near term. The cut took adjusted EBITDA guidance to $220-225 million from $240-250 million.

How did Koppers generate record free cash flow while profit fell?

Operating cash flow reached a record $126.9 million for the nine months ended 30 September 2026, up from $77.4 million. The company credited improved working capital, including the timing of customer receipts and vendor payments plus lower inventory, and noted the prior-year period included roughly $14 million of pension funding. Free cash flow of $92.0 million came after $34.9 million of capital expenditures.

What does the CMC segment weakness mean for Koppers?

Carbon Materials and Chemicals adjusted EBITDA fell 60.9 percent to $6.1 million, with margin dropping to 5.8 percent from 14.4 percent. Koppers attributed the decline to $9.0 million of higher raw material costs and $1.7 million of lower utilization from feedstock quality issues and the accelerated Stickney closure. Carbon pitch prices were about four percent higher globally, but reduced volumes outweighed that pricing.

Bottom Line

Koppers cut 2026 adjusted EBITDA guidance by roughly $20 million at the midpoint, betting record cash flow and 2027 commercial resets can bridge the margin gap.
