Neste Oyj has lowered its 2025 EBITDA guidance due to softening refining margins and headwinds facing its renewable product lines. The Finnish energy company, a major producer of sustainable aviation fuel and renewable diesel, is seeing a more challenging pricing environment and delays in customer ramp-ups. This profit warning highlights the volatility of the low-carbon fuel market, where profitability depends heavily on the spread between waste feedstock costs and fossil fuel benchmarks. The shift reflects broader challenges in the European clean-fuels sector as regulatory mandates and market demand evolve.
