Accelleron delivers strong half-year results and accelerates investments for future growth

Marine new builds and data centers continue to underpin growth

• Revenues reached USD 737.3 million, +21.3% year-on-year
• Operational EBITA increased to USD 189.7 million (+22.5% YoY)
• Operational EBITA margin increased to 25.7% (+0.2 ppts YoY)
• Net income increased to USD 150.8 million (+31.5% YoY)
• Accelerated investments to capture future growth
• Full-year 2026 organic revenue growth guidance raised to 14–17%

Baden, Switzerland, August 27, 2026 – Accelleron, a global technology leader in turbocharging, fuel injection, and digital solutions in the marine and energy industries, reports another strong set of half-year results, building on the momentum seen in 2025. “Marine continued to develop strongly, while data center expansion in the U.S. led to increasing demand for prime power applications. To capture future growth, especially in data center-related power generation applications, we invested USD 31 million in the first six months of 2026, more than 40% above the first half of 2025,” said Accelleron CEO Daniel Bischofberger. “Given our half-year results and the positive dynamics in our core markets, we are raising our guidance for full-year 2026 organic revenue growth to 14–17%.”

Revenues in the first six months of 2026 reached USD 737.3 million, representing a year-on-year increase of 21.3% (17.2% organic). Accelleron’s Operational EBITA increased by USD 34.8 million, or 22.5%, reaching USD 189.7 million. The Operational EBITA margin rose by 0.2 percentage points to 25.7%. Net income increased by USD 36.1 million, or 31.5%, to USD 150.8 million. Free cash flow conversion stood at 58.4% (H1 2025: 70.3%), mainly reflecting increased investments to support future growth.

Medium & Low Speed segment

Revenues in the Medium & Low Speed segment increased by USD 69.7 million, or 15.2% (11.3% organic), to USD 528.5 million, compared to the first half of 2025.

Growth was driven by continued strong demand in merchant marine new builds. Fuel injection revenues developed in line with expectations.

Service growth in the Medium & Low Speed segment was driven by fuel efficiency upgrades, an increasing number of vessels under full-cover service agreements, and continued high utilization in the merchant marine and cruise segments. Service activity for medium-speed energy applications also contributed to growth, supported by regular maintenance and reliability-driven investments at power plants.

Operational EBITA increased by USD 18.7 million, or 16.1%, to USD 134.9 million, compared to the first half of 2025. Growth in the lower-margin product business was more than offset by structural leverage, resulting in an increased Operational EBITA margin of 25.5%, up by 0.2 percentage points.

High Speed segment

Revenues in the High Speed segment increased by USD 59.7 million, or 40.0% (35.5% organic), to USD 208.9 million, compared to the first half of 2025.

Revenues from turbochargers in gas‑fired prime power applications for data centers in the U.S. continued to grow, supported by capacity expansion at engine OEMs. Revenue growth in diesel‑fired backup power was constrained by OEM capacity allocation. In gas compression, demand in North America remained strong, supported by investments in pipelines due to increasing domestic and export demand for natural gas.

Service revenues in the High Speed segment grew strongly, driven by sustained U.S. natural gas demand, which resulted in continued momentum in turbocharger remanufacturing activity for gas compression applications. Service revenues from stationary power applications remained stable, while the installed base continued to grow.

Operational EBITA increased by USD 16.1 million, or 41.6%, to USD 54.8 million, compared to the first half of 2025. Additional costs along the value chain were more than offset by strong structural leverage, resulting in an increased Operational EBITA margin of 26.2%, up by 0.3 percentage points.

Positive outlook and raised guidance

“Demand remains robust across our core markets, supported by ongoing data center expansion and continued activity in marine new builds. While we expect a steady appetite for full-cover service agreements, growth in upgrade and retrofit solutions is expected to level off due to the postponement of the IMO Net Zero Framework,” said Bischofberger. “We are investing further in capacity, technology, and our people to ensure we can deliver for our customers, while executing on our balanced capital allocation framework, including the share buyback program launched in May.”

Based on the strong half-year results, Accelleron is raising its full-year 2026 organic revenue growth guidance to 14–17% (previously 9–14%). The Operational EBITA margin guidance for 2026 is confirmed at 25–26%.
