Strategy
Planet
In 2025, LISI defined its climate strategy through rigorous scenario modeling, setting a goal that is both ambitious and realistic. The trajectory for reducing greenhouse gas emissions by 2030 is underway. Projects for self-production of renewable energy and continuous optimization of industrial processes have been expanded. Efforts to reduce water consumption have also intensified.

** 100% of sites in water stress zones defined an action plan in 2023, and 67% implemented their action plan in 2025.
Beyond these indicators, it is concrete innovations that embody our trajectory. From reducing the buy-to-fly ratio in aerospace to enabling the electrification of heavy trucks in automotive, LISI translates its environmental commitments into differentiating industrial solutions.
Used in series production for complex titanium parts, the TYX technology is reaching new milestones. First flight applications are expected by 2027.
CUTTING BUY-TO-FLY:
THE TYX CHALLENGE
Initially deployed in series production for titanium structural components (flanges, joining fittings), TYX technology (see box below) is now being extended to aluminum parts. Prototypes of three aluminum part numbers were delivered in 2025, and early customer feedback confirms the relevance of the approach: machining and assembly trials demonstrate highly repeatable geometry. “These tests have shown equivalence, and in some cases improved performance versus forged parts in terms of dimensional conformity,” notes Elisabeth Willocq, R&T Director – Engine and Structural components, LISI AEROSPACE. Current work is focused on fully demonstrating process repeatability and robustness in preparation for qualification and certification phases.
In December 2025, a TRL5* maturity milestone (validation in a representative environment) was achieved with a customer on aluminum parts. The objective is to reach TRL6 (demonstration on an industrial pilot line) in the third quarter of 2026, a prerequisite for the launch of industrialization of an initial part number targeted for entry into service at the end of 2027. The award of an initial serial production contract using this technology marks the beginning of its industrial deployment. “This new approach enables lower material consumption than conventional processes—and therefore a reduced buy-to-fly ratio—as well as improved machinability,” notes Mathieu Minvielle, Industrial Director, LISI AEROSPACE Marmande Beyssac. Beyond material performance, TYX technology also opens up new design possibilities, enabling geometries that are difficult to achieve with conventional processes.

WHAT ARE WE TALKING ABOUT?
Developed by LISI AEROSPACE, TYX technology is based on a simple principle: deform only the material that is strictly necessary. It uses less material and produces metal parts with T-, Y-, or X-shaped sections using low-power hydraulic presses—typically in the 1,000 to 3,000-ton range—where equivalent forged parts may require power levels more than 20 times higher. By concentrating forming forces only where needed, the process significantly reduces applied loads, energy consumption, and stress on tooling.
Compared with conventional methods, the TYX process enables lower material consumption and therefore reduces the buy-to-fly ratio.

ELECTRIFIED HEAVY-DUTY VEHICLES
LISI AUTOMOTIVE DEPLOYS ITS SOLUTIONS
The transition to e-mobility is fundamentally reshaping the commercial vehicle industry. Against this backdrop, LISI AUTOMOTIVE is accelerating the diversification of its product offering to meet the specific needs of the emerging electric heavy-duty vehicle market, a segment with strong technological and industrial potential. Historically recognized for its expertise in fastening solutions and high-voltage cable supports, LISI AUTOMOTIVE also designs and manufactures key components for electrical interface protection, ensuring long-term reliability in environments subject to high vibration and heavy load conditions. “Our high-voltage cable supports are now a benchmark in this market. They meet very high multifunctional requirements and are already in serial production,” explains Bernd Brecheis, Sales Director, LISI AUTOMOTIVE Heidelberg, Germany. “A chassis-mounted cable support design combining multiple materials has already been successfully industrialized.”
DEVELOPMENT OPPORTUNITIES
Beyond this initial achievement, LISI AUTOMOTIVE sees significant development opportunities with other truck manufacturers and major Tier 1 suppliers, for whom equivalent solutions are not yet in serial production. The objective is clear: to leverage this initial technical success to establish a strong and sustainable position in a fast-growing segment.
In parallel, LISI AUTOMOTIVE is developing dedicated fastening solutions for battery systems, a critical challenge for 40-ton electric trucks subject to significant weight and vibration constraints. Steel mounting fastening solutions, designed using optimized architectures, already meet these requirements while remaining cost-competitive.
“Our solutions are capable of withstanding extreme loads while delivering significant economic advantages over low-cost competitors,” explains Christoph Rieger-Bender, Key Account Manager, LISI AUTOMOTIVE Heidelberg. Finite element analysis (FEA), conducted in close collaboration with LISI AUTOMOTIVE’s R&D team in Grandvillars and the relevant customers, has validated component performance under shock loads of up to 21 g in vertical acceleration, as well as the dynamic vibration loads typical of heavy-duty applications.
At a time when the entry of new players—particularly from Asia—is increasing cost pressure, LISI AUTOMOTIVE is confirming the relevance of its three-pronged strategy: a proactive commercial approach, close co-development with customers, and strengthened cross-functional collaboration across the division’s R&D entities. This dynamic now enables the company to deliver differentiated solutions, accelerate development cycles, and establish a sustainable position in new markets.

A MARKET UNDERGOING RAPID TRANSFORMATION
The electrification of the European heavy-duty vehicle market is accelerating. Driven by the European Green Deal, electrification is progressively becoming an industry standard in order to meet the CO₂ reduction targets set by Brussels. Battery electric trucks currently represent the main development pathway, although hydrogen solutions based on fuel cells are emerging as a promising alternative for long-haul applications. In a context where charging infrastructure remains limited, next-generation diesel powertrains continue to play a role as a transitional technology.
