Heidelberg Materials shares are down about 24% over the past year even after record 2025 results and a fresh buyback. The stock trades around EUR 144 after starting the period at EUR 195. Simply Wall St lays out two fair value scenarios: a bullish EUR 234 case built on 6.1% annual revenue growth and margins rising to 12% by 2028, and a bearish EUR 91 case where carbon costs and competition hold margins near 10.3%. The H1 2026 numbers show revenue of EUR 10.6 billion, up from EUR 10.4 billion, with net income at EUR 743 million. Net margin improved only slightly to 7.0%. That leaves the core question unresolved: whether decarbonization and efficiency programs can lift profitability enough to offset rising carbon costs and weaker construction demand. For investors tracking climate exposure, Heidelberg is a useful case study. The gap between the bull and bear cases is mostly a bet on carbon pricing and whether cleaner cement production can be priced into the market. Buyers are paying for execution on automation, cost cuts, and portfolio reshaping, not for a rebound in cement volumes.
