Accelleron raises revenue guidance for 2025 after impressive growth in the first half-year

Continued market share gains in turbochargers and high demand for marine services and power generation

• Half-year revenues reached USD 608.0 million, +20.1% year-on-year in constant currency
• Constant currency revenue growth for the full year expected to be in the range of 16-19%
• Guidance for operational EBITA margin¹ confirmed at 25-26%

Baden, Switzerland, July 15, 2025. Accelleron, a global technology leader in turbocharging, fuel injection, and digital solutions in the marine and energy industries, has continued its growth trajectory in the first six months of 2025 and is now increasing its outlook for the full year.

Accelleron’s revenue growth of 20.1% in constant currency (20.3% nominal, reaching USD 608.0 million) was propelled by continued market share gains in turbochargers and high market demand for marine services, especially retrofits, as well as for backup, balancing, and prime power applications. The markets have not cooled down in the first half-year, despite geopolitical disruptions.

The company expects the positive momentum in the marine and energy markets to continue in the second half of the year, assuming no significant negative changes to the current U.S. tariff regime. Based on the impressive revenue growth in the first half-year and the outlook for the second half of 2025, Accelleron is raising its guidance and now expects constant currency revenue growth of 16-19% in 2025.

Accelleron confirms the guidance for the operational EBITA margin provided on March 13, 2025, which is 25-26%.

Accelleron’s Half-Year Report 2025 will be published on August 27, 2025.
