Swiss industrial group Accelleron Industries (SIX: ACLN) posted H1 2026 revenue of $737 million, a 21.3% increase from the prior-year period, as demand from data centers and marine sectors accelerated.
Operational EBITA climbed 22.5% to $190 million, lifting the EBITA margin by 20 basis points to 25.7%. Net income rose 31.5% to $151 million, while free cash flow increased to $88 million. CEO Daniel Bischofberger attributed the growth to strong order intake, particularly in data center prime power applications where deliveries more than doubled to about 5 gigawatts of installed capacity.
The company’s high-speed turbocharger segment surged 40% year-over-year to $209 million, driven by 35.5% organic growth, while the medium and low-speed segment grew 15.2% to $529 million with 11.3% organic expansion. Bischofberger noted that data center-related revenues now account for nearly 9% of total sales, up from about 5% a year earlier, and are projected to reach roughly 10% for the full year.
Accelleron also highlighted strategic milestones, including cumulative orders of over 10,000 units for its A100-L and A200-L series, representing an installed power base of about 110 gigawatts. The company secured a long-term service agreement with the City of Denton, Texas, for fast-start power generation tailored to peaking operations, and its ACCX300-L platform received initial orders for more than 50 vessels.
Capital expenditure rose over 40% to $31 million, with management indicating plans to allocate roughly 20% of 2026–2028 investments to manufacturing and R&D upgrades in Switzerland, 50% to equipment replacement, and 30% to additional production capacity. Nearly two-thirds of total investments are earmarked for Switzerland, with the remainder distributed across China, Italy, and the service network.
The company raised its full-year organic revenue growth guidance to 14–17%, up from the prior 9–14% range, while maintaining its operational EBITA margin target of 25–26%. Shares rose 3.34% to $80.45 following the presentation, within a 52-week range of $60.70 to $90.50.
