Accelleron Industries AG reported strong first-half results, with revenue climbing 21.3% to $737.3 million and net profit rising 31.5% to $150.8 million, prompting an upward revision to its full-year outlook.
The Swiss engineering group, which supplies turbochargers, fuel-injection systems and digital solutions for maritime and energy sectors, said organic revenue growth reached 17.2% in the six months to June 30. Operating EBITA increased 22.5% to $189.7 million, lifting the margin to 25.7% from 25.5% a year earlier.
CEO Daniel Bischofberger attributed the performance to sustained demand in two key areas: ongoing shipbuilding activity in commercial shipping and expanding U.S. data-center construction, which is driving demand for primary energy applications. Accelleron invested $31 million in the first half, up more than 40% from the same period last year, to support future growth, particularly in power-generation applications for data centers.
The Medium & Low Speed segment, which serves marine and power-generation markets, posted revenue of $528.5 million, up 15.2% year-over-year, with organic growth of 11.3%. Growth was supported by upgrades to improve fuel efficiency, a rising number of full-service contracts and high utilization rates in commercial and cruise shipping. Service revenue for medium-speed engines in power generation also contributed, driven by maintenance work and reliability-focused investments in thermal power plants.
Operating EBITA in this segment rose 16.1% to $134.9 million, with the margin improving by 0.2 percentage points to 25.5%, as structural leverage offset margin pressure in lower-margin product lines.
The High Speed segment, focused on turbochargers and related services, reported revenue of $208.9 million, up 40% year-over-year, with organic growth of 35.5%. Demand for gas-fired turbochargers in U.S. data centers continued to expand, supported by engine manufacturer capacity expansions. Revenue from diesel-based standby power applications was constrained by engine manufacturer allocations, while gas compression demand remained robust in North America, driven by pipeline investments to meet rising domestic and export natural-gas demand.
Operating EBITA in the High Speed segment increased 41.6% to $54.8 million, with the margin rising by 0.3 percentage points to 26.2%, as cost pressures along the value chain were outweighed by structural leverage.
Accelleron raised its full-year organic revenue growth guidance to 14-17% from a prior range of 9-14%, while maintaining its 2026 operating EBITA margin forecast of 25-26%. The company also noted that while demand for full-service contracts remains strong, growth in upgrades and retrofits may moderate as the IMO Net-Zero framework shifts focus.
The group’s net debt-to-equity ratio stood at 0.7 at mid-year, down from 0.8 at the end of 2025, and free cash flow conversion declined to 58.4% from 70.3% a year earlier, primarily due to higher growth investments. Unadjusted earnings per share rose 30.8% to $1.53.
Accelleron, listed on the SIX Swiss Exchange under ticker ACLN, employs over 3,200 people across more than 100 locations in 50 countries and has operated for over a century as a technology leader in heavy-duty industrial applications.
