InterAlpen Partners and Hale Capital Partners Complete $25 Million Investment in Acutronic Group to Accelerate Global Defense Technology Leadership

Investment backs a rare transatlantic defense technology company — supplying mission-critical propulsion, simulation, and motion control systems to the world’s leading defense primes — as the US and NATO allies undertake the most significant military build-up since the end of the Cold War.

ZURICH, SWITZERLAND & AUSTIN, TEXAS — InterAlpen Partners, a private equity firm specializing in founder-led growth companies in mission critical industries, announced the first close of a strategic investment in the Acutronic Group (Acutronic), the global leader in Simulation & Test solutions for the aerospace and defense sector and a rapidly-scaling supplier of Aerospace Components for drones, missiles, and autonomous platforms. Hale Capital Partners, a New York-based investment firm with nearly two decades of defense technology experience, participated in the investment as an industry-specialist investor.

Founded over 50 years ago and dual-headquartered in Zurich, Switzerland and Austin, Texas, Acutronic operates three specialized lines of business: its Aerospace Components Division manufactures micro-turbine engines, power systems, and actuation solutions; its Simulation & Test Division produces rate tables, hardware-in-the-loop simulators, and shaker tables; and its Stabilized Platform team engineers gimbaled and related positioning systems. The company operates facilities in Austin, Texas, Pittsburgh, Pennsylvania, Switzerland, Germany, France, and India, representing a genuinely global delivery capability with local production and engineering. Acutronic’s product lines serve as the invisible backbone behind countless drone, missile, space, and transportation platforms.

The company enters this partnership from a position of sustained operational strength. Acutronic achieved significant growth in 2025 — its fourth consecutive year of record revenue, bookings, and profitability — and has expanded adjusted EBITDA margins for four straight years. Its blue-chip customer base includes almost all aerospace and defense primes in the US, Europe, and allied nations globally, with new purchase orders recently received in support of the latest industry programs.

The investment arrives at a structural inflection-point for global defense. The age of a small number of expensive, exquisite platforms has given way to higher volume “attritable” systems, loitering munitions, air launched effects, and one-way attack drones - that require precisely the kind of reliable micro-turbine propulsion, electric power systems, and precision actuation that Acutronic manufactures. The company’s Austin, Texas facility is one of the only facilities in the United States capable of mass-producing small jet engines at the scale required to match the “affordable mass” strategies being fielded by adversaries.

Simultaneously, Europe faces its most consequential defense build-up in a generation: NATO allies have committed to raising defense spending toward five percent of GDP over the coming decade. Acutronic, as the dominant European supplier of hardware-in-the-loop simulators, is uniquely positioned to capture this historic demand.

“The structural shift in how nations fight and deter adversaries is not a passing trend — it is a generational transformation. Acutronic sits at the absolute center of it: supplying the propulsion, simulation infrastructure, and autonomous systems hardware that turns defense policy into operational reality. We are proud to partner with the Acutronic leadership team to accelerate their global growth at this critical moment for Western security.”

— Stephen George, Founding Partner, InterAlpen Partners

Acutronic’s momentum across U.S. defense programs has accelerated materially over the last year. Acutronic has been selected to deliver jet engines for a number of market-leading platforms, with demand for follow-on production orders seen as substantial. Specialized test equipment and stabilized platforms for next-generation missiles, directed-energy systems, and electro-optic sensors are currently in assembly at the company’s Pittsburgh facility.

“Hale Capital has spent nearly two decades building deep relationships across the national security community — and we recognize exceptional defense technology assets when we see them. Acutronic has built exactly the kind of trusted, proven, mission-critical platform that the defense industrial base needs more of: reliable, transatlantic, and purpose-built for the era of autonomous and attritable systems. We are delighted to support InterAlpen and the Acutronic team as this company enters its next chapter of growth.”

— Martin M. Hale Jr., Chief Executive Officer, Hale Capital Partners

Europe and partner countries in Asia represent a critical growth vector for Acutronic. With deep operational roots in Switzerland, Germany, France, and India, Acutronic is uniquely positioned as a trusted supplier for aerospace & defense procurement — providing hardware-in-the-loop simulators, rate tables, and vibration test systems that cannot be readily sourced elsewhere. As governments commit to significant and sustained increases in defense budgets, Acutronic’s installed base, customer relationships, and product suite place it ahead of competitors in its core markets.

“For more than fifty years, Acutronic has been the partner of choice when quality, precision, and customer service are non-negotiable. I am immensely grateful for all members of the Acutronic team, who have been through countless challenges over the years and have positioned the company where it sits today. The investment and strategic partnership with InterAlpen and Hale Capital infuses our company with the capital and strategic backing to do what the moment demands: build the world’s best micro-turbines, expand our European commercial footprint, and invest in next-generation technology to meet our customers’ needs.”

— Florian Aigrain, Chief Executive Officer, Acutronic Group

Proceeds from the investment will be deployed across three priorities: realizing new product development, across aerospace components, shaker tables, and stabilized platforms; financing capital expenditures to expand production capacity; and providing working capital for growth activities. Acutronic’s strategic growth plan targets strong revenue growth in the coming years, through organic expansion of the core Simulation & Test business, high-growth scaling of the Aerospace Components Division, and a disciplined M&A program targeting complementary defense technology businesses.
