Sources: FY2023 Annual Report highlights (FY2021–FY2023), Q4 FY2023 8-K (FY2022–FY2023 detail), Q4 FY2025 8-K (FY2024–FY2025). FY2021 detail beyond ARS highlights NR. Gross profit is computed as net sales less cost of sales (Koppers reports D&A separately, so this is pre-D&A gross profit). Ratios are derived by the analyst.

Income statement: notes and sources

Notes: FY2021 diluted EPS is continuing operations (ARS). FY2021 basic EPS from roic.ai (secondary). FY2024 DPS of 0.29 is consistent with dividends paid (USD 5.9M) but declared-per-share for 2024 is from a secondary source. Management states FY2025 was the sixth consecutive year of adj. EPS above USD 4 (Q4 FY2025 call), implying FY2020–FY2021 adj. EPS also exceeded USD 4 (exact FY2021 figure NR).

Margins (%)

Revenue CAGR FY2021–FY2025: +2.9%; FY2022–FY2025: -1.7%.

Balance sheet

Notes: FY2021 total debt is the ARS "total debt" figure (may be gross of issuance costs). Gross debt outstanding at 31 Dec 2025 was USD 928.3M per the 10-K risk factors (vs USD 919.2M carrying value).

Interim balance sheet, 30 June 2026 (Q2 FY2026 8-K): total assets USD 1,722.3M; cash USD 40.7M; debt USD 897.6M (4.9 current + 892.7 long-term); net debt USD 856.9M; PP&E USD 482.1M (down from 650.9M at FY2025 year-end after impairment); goodwill USD 329.1M; intangibles USD 96.6M; total equity USD 387.0M (down from 574.3M).

Cash flow

H1 FY2026: OCF USD 96.3M (record), capex USD 23.7M, FCF USD 72.6M (record), repurchases USD 43.9M, total shareholder returns USD 47.4M (Q2 FY2026 8-K). LTM to June 2026 (derived): OCF ~USD 191.0M; capex ~USD 52.3M; FCF ~USD 138.7M.

Ratios (derived)

Methodology: ROIC = EBIT x (1 - effective tax rate) / (debt + equity - cash), year-end. CCC uses year-end receivables, inventories and payables against sales and cost of sales (excl. D&A). FY2022 ROE on year-end equity would be 15.7%.

At 30 June 2026 (LTM, derived): net debt/LTM adj. EBITDA = 856.9 / 244.4 = 3.51x; debt/equity = 2.32x (equity reduced by impairment).

Commentary on trends, inflections and drivers

Revenue. FY2021–FY2023 growth (USD 1.68bn to a record USD 2.15bn) was price-led as Koppers passed through raw material inflation (renegotiated PC contracts; crosstie and pole price increases). FY2024 marked the inflection: CMC pitch prices collapsed (Q4 FY2023 pitch prices -24.3% globally) and PC volumes softened. FY2025 sales fell 10.2% to USD 1.88bn as every segment declined; management attributes roughly 4 points of the decline to the phthalic anhydride exit and KRS sale, with the remainder from reduced market share and softer demand (Q4 FY2025 8-K and call). H1 FY2026 sales grew 1.5% with PC volume recovery offsetting RUPS price erosion.

Profitability. The defining feature of FY2025 is margin resilience on lower sales: adj. EBITDA fell only 1.9% while sales fell 10.2%, lifting adj. EBITDA margin to a multi-year high of 13.7%; adjusted SG&A fell 15% (Q4 FY2025 call) and Catalyst delivered ~USD 46M of benefits. Gross margin (pre-D&A) expanded from 17.4% (FY2022) to 23.8% (FY2025). GAAP earnings are noisier: FY2024 net income was depressed by USD 16.9M impairment/restructuring and a USD 10.7M loss on asset sales; FY2025 by USD 51.9M restructuring (phthalic anhydride) and a USD 27.1M pension settlement loss, partly offset by USD 34.2M mark-to-market copper hedge gains. FY2026 GAAP is dominated by the Q2 USD 215.8M impairment, restructuring and plant closure charge, driving a H1 FY2026 net loss of USD 140.4M.

D&A and interest. D&A rose from USD 56.1M (FY2022) to USD 73.6M (FY2025) following heavy FY2021–FY2023 capex (USD 105–125M/year, including North Little Rock and Leesville plant investments). Interest expense peaked at USD 76.2M (FY2024) and fell to USD 66.1M (FY2025) and USD 30.0M in H1 FY2026 (vs 33.9M), reflecting lower SOFR, the 2024 TLB repricing and debt reduction.

Balance sheet. Net debt has been range-bound at USD 775–890M for five years; leverage has hovered at 3.0–3.5x adj. EBITDA. The Brown Wood acquisition (FY2024) pushed net debt up ~USD 113M. Working capital intensity increased in FY2025 (CCC 104.5 days; modified NWC 25.8% of sales vs a 21.0% incentive target, per DEF 14A 2026) as payables fell sharply (USD 179.1M to 122.4M) — reversed in H1 FY2026, when payables rose USD 44.5M and inventories fell USD 19.2M.

Cash flow. FCF inflected as capex normalised (USD 120.5M in FY2023 to 55.0M in FY2025) and pension funding rolled off. FY2026 guidance implies record FCF of USD 110–130M; H1 FY2026 delivered USD 72.6M. Capital allocation has prioritised buybacks (USD 50.8M FY2024, USD 38.2M FY2025, USD 43.9M H1 FY2026) over faster deleveraging — a point of debate given leverage above 3x.

Equity erosion. The Q2 FY2026 impairment reduced total equity from USD 574.3M to USD 387.0M, raising book leverage materially, though covenants are based on net leverage and interest coverage rather than book equity (10-K FY2025).

Management guidance

FY2026 (6 Aug 2026): sales USD 1.9–2.0bn; adj. EBITDA USD 240–250M (toward lower end of prior range); adj. EPS USD 3.80–4.20; OCF USD 165–185M; capex USD 55M; FCF USD 110–130M. Management expects the tougher margin environment (input costs, freight) to persist through 2026 and is positioning for a "step change" in profitability in 2027 from Stickney and footprint actions (Q1 FY2026 8-K). Consensus growth expectations for FY2027: NR.

Bull case

1. Cash inflection is real: H1 FY2026 FCF of USD 72.6M already exceeds full-year FY2025 FCF (USD 67.5M); guided FY2026 FCF of USD 110–130M implies a mid-teens FCF yield at ~USD 50 per share.

2. Self-help into 2027: Stickney (USD 15–20M EBITDA uplift), idling of Vance/Florence, and Catalyst savings could lift adj. EBITDA back above USD 260–270M even without market recovery, while removing CMC's most volatile US asset.

3. Utility and PC momentum: domestic pole volumes +16% and PC volumes +11% in Q2 FY2026, with PC margin at 22.4%, suggest the two higher-quality franchises are gaining share.

Bear case

1. Guidance credibility: two FY2026 EBITDA guidance cuts in six months and a USD 215.8M impairment suggest management's earnings visibility is poor.

2. Rail is structurally weaker: Class I customers have cut tie volumes two years in a row, prices are eroding, and insourcing by at least one Class I (per Stella-Jones) threatens the RUPS core.

3. Leverage and capital allocation: net leverage ~3.5x LTM with book equity down to USD 387M, yet USD 43.9M of buybacks in H1 FY2026; a further downturn could pressure covenants or force asset sales.

Key catalysts and monitorables (next 12 months)

• Q3 FY2026 results (expected early November 2026, date NR): confirmation of FY2026 guidance and Stickney closure costs.

• Completion of Stickney shutdown (target 30 Sep 2026) and Nyborg ramp in Q4 2026.

• FY2027 guidance (expected late February 2027): quantification of 2027 "step change".

• Class I 2027 tie procurement plans and Railway Tie Association data.

• US copper tariff developments (refined copper decision) and COMEX-LME spread.

• Labour contract renewals (three facilities, ~160 employees, 2026).

• CFO Brenner's capital allocation framework: debt reduction vs buybacks; any refinancing of the revolver.

• Potential bolt-on M&A in PC/UIP.

• Further impairments or CMC portfolio actions in Australia/Europe.

Analyst verdict

Koppers enters late 2026 as a company whose reported numbers look worse than its underlying trajectory, but whose underlying trajectory is less robust than management's 2027 narrative implies. On the positive side, the transformation is tangible: Catalyst took USD 46M of cost out in FY2025, adjusted EBITDA margin reached 13.7% on shrinking sales, and cash generation has inflected sharply, with record first-half operating and free cash flow in 2026. The portfolio is being deliberately reshaped toward the two businesses that deserve capital — utility poles, which ride a multi-year grid investment cycle, and Performance Chemicals, which has regained volume and delivered a 22.4% margin in Q2 FY2026. Exiting phthalic anhydride, bridge services and now Stickney distillation removes earnings volatility and capital demands.

Against that, the core railroad business — still the largest single profit pool — faces a genuinely tougher market: customers are buying fewer ties, pricing is falling, and a peer reports at least one Class I treating in-house. CMC remains a drag, with first-half 2026 EBITDA down two-thirds. Leverage around 3.5x, two guidance cuts in six months, a USD 215.8M impairment and continued buybacks ahead of deleveraging all argue for a valuation discount. The stock's ~80% rise from its late-2025 trough has already priced a meaningful part of the recovery: at ~USD 51, the shares trade on ~7.4x guided EBITDA and ~13x adjusted EPS.

Our synthesis is a neutral-to-constructive stance: the risk-reward depends on evidence that 2027 earnings reach the ~USD 270M+ EBITDA run-rate implied by cost actions, and that free cash flow is prioritised toward bringing leverage below 3x. The Q3 FY2026 print, the FY2027 guide and Class I procurement signals are the decisive datapoints. Investors should treat CMC as a declining option rather than a core value driver and underwrite the equity on RUPS utility and PC cash flows.
