Future Outlook

Koppers forecasts 2026 net sales between $1.9 billion and $2.0 billion, Adjusted EBITDA between $250 million and $270 million, and Adjusted EPS between $4.20 and $5.00. The company expects to drive significant improvement in adjusted EPS and free cash flow in 2026, attributing this to benefits from the Catalyst program, moderate sales recovery, a tighter operating footprint, lower interest costs, a lower effective tax rate, and a lower share count. Normalized capital expenditures and the lack of major pension contributions are expected to lead to record free cash flow generation.

Key Dates

Recommendation

Koppers reported mixed financial results for Q4 and full-year 2025, with sales and adjusted profitability declining but GAAP net income and diluted EPS showing strong recovery from the prior year. The company's 'Catalyst' transformation program is yielding benefits, and the 2026 outlook projects significant improvements in adjusted EPS and free cash flow, driven by strategic cost reductions and network optimization. However, market share shifts, competitive pricing, and raw material cost increases remain headwinds. Given the strategic initiatives are in progress and the future outlook is positive but not without challenges, a 'hold' recommendation is appropriate for investors to observe the execution of the 2026 plan and its impact on sustained profitability and market share.
