FINANCIAL INFORMATION

LISI Group reported revenue of €468 million in the first quarter of 2026, up 10.9% on a like-for-like basis

The LISI Group’s revenue increased by 5.9% in the first quarter of 2026 compared to the same period in 2025, following the disposal of the LISI MEDICAL division on October 31, 2025. This change reflects a highly unfavorable currency effect (-€24.0 million) linked to the weakening of the average U.S. dollar exchange rate against the euro.

• LISI AEROSPACE : revenue up 10.4% in the first quarter of 2026 compared to a high base of comparison in the first quarter of 2025 (16.6%), reaching a record level of €325.1 million; at constant exchange rates, growth was robust at 17.6%;
• LISI AUTOMOTIVE : revenue down -3.5% amid a contraction in global production among its major customers (down -1.4% compared to 2025).

Consolidated revenue as of the end of March 2026 includes the following items:

• a significant adverse currency effect of -€24.0 million (5.1% of revenue), resulting primarily from the weakening of the average exchange rate of the U.S. dollar against the euro;
• a positive scope-of-consolidation effect of €1.7 million (0.4% of revenue) related to the consolidation of LISI AUTOMOTIVE Hungary in October 2025.

Revenue growth, adjusted for currency fluctuations and changes in scope, amounted to +10.9% over the first three months of the year.

1 The change at constant scope and exchange rates is calculated: • by converting the sales of the companies whose financial statements are denominated in foreign currencies at the average rate of the year N-1 or the month M-1; • by converting the sales invoiced in currencies other than the local currency at the average rate of the previous year or previous month M-1; • by restating the entries into or exits from the scope to ensure comparability of data.

2 The consolidated data for the first quarter of 2025 does not include LISI MEDICAL’s revenue, which amounted to €44.7 million.

• Global air traffic remains strong in the first quarter Air traffic remains strong despite short-term fuel price increases, although airlines could see their costs rise sharply over the long term. Demand for new, more fuel-efficient aircraft remains very strong, and ramp-up targets are being maintained.

The Airbus A320 family continues to grow (64 aircraft per month today, with a target of 75 per month in 2027), as does the A350 program. At Boeing, the ramp-up of production for the B737 MAX and B787 has gained momentum. The strong performance of the helicopter and defense segments, which account for between 10% and 15% of the division’s business, is also helping to support overall demand.

• A record first quarter, despite a gradual start Revenue for the LISI AEROSPACE division reached a record €325.1 million at the end of March 2026, up 10.4% from the already high base of the first quarter of 2025 (up 16.6%).

With a 13.8% increase, first-quarter 2026 revenue for the “Fasteners” business in the United States posted the strongest growth. The “Fasteners” business in Europe and the “Structural Components” business also posted strong growth, up 11.1% and 8.3%, respectively, compared to the first quarter of 2025.

Adjusted for currency effects and excluding changes in scope, the LISI AEROSPACE division’s revenue posted sustained organic growth of +17.6% over the first three months of the year.

• Global automotive market under pressure Global light vehicle registrations fell by -5.2% at the end of February 2026 compared to the same period last year. This decline was widespread across all major geographic regions: China recorded the sharpest drop (-21.6%), followed by the NAFTA region (Canada, United States, Mexico) at -1.6% and Europe at -0.8%.

• Global light vehicle production down Revenue for the LISI AUTOMOTIVE division totaled €143.0 million at the end of March 2026, down 3.5% compared to the same period of the previous fiscal year. Adjusted for currency effects and the change in scope resulting from the integration of LISI AUTOMOTIVE Hungary in October 2025, the LISI AUTOMOTIVE division’s revenue declined by 2.6% compared to the same period of the previous fiscal year, reflecting:  a -1.4% decline in global production of the division’s automotive manufacturer customers;  a clearly stated commitment to continue repositioning the product portfolio toward higher-value-added parts, a process initiated several years ago. This is reflected in consistently strong order intake for new products (9.0% of revenue for the quarter).

The division is pursuing a targeted growth strategy that prioritizes expansion in promising and profitable segments (braking systems, interior trim), agility in adapting product lines, and positioning in electromobility.

OUTLOOK AND COMMENTS ON FINANCIAL IMPACT ACTIVITY

The long-term outlook remains dependent on the evolution of global geopolitical tensions, which could affect demand in the aerospace sector, the overall inflation rate, and the euro/U.S. dollar exchange rate. In this environment of low visibility and high volatility, operational agility will be critical.

LISI AEROSPACE

Market momentum in the aerospace sector remains favorable across all civil platforms. The helicopter and defense segments are also maintaining their positive momentum. Gaining market share with major strategic customers (particularly through the renewal of major contracts in 2025 and 2026) reinforces this momentum.

Furthermore, LISI AEROSPACE’s order backlog for 2026 remains very solid, and capacity expansions are a priority.

The LISI AEROSPACE division is benefiting from higher delivery volumes, which help better absorb fixed costs, and from continuous productivity improvements driven by the implementation of the plan to renew production equipment.

LISI AUTOMOTIVE

In a global automotive market characterized by low visibility, LISI AUTOMOTIVE is continuing the structural initiatives undertaken over the past several years, focused on:  positioning itself in the new vehicle segment and maintaining a high level of new orders for high- -added-value products;  adjusting the fixed-cost structure to maintain competitiveness and support the sector’s profound changes.

Operationally, the LISI AUTOMOTIVE division is benefiting from the ramp-up of new high-added-value products with an industrial footprint in regions with attractive costs.

The priority initiatives for 2026 are as follows:  the implementation of the industrial reorganization project involving the discontinuation of manufacturing activities at its Puiseux-Pontoise site (France), the transfer of production to other sites within the “Clipped Solutions” business, and the relocation of the sales teams and design office to the LISI AEROSPACE site in Saint-Ouen l’Aumône;  the continued operational and functional integration of LISI AUTOMOTIVE Hungary in Györ, as well as the development of targeted industrial capacity at the division’s sites in China, Mexico, and Morocco;  inflation in certain raw material costs will be gradually passed on to prices during the fiscal year.

LISI Group

The aerospace development plan is the Group’s main growth driver, with solid visibility for the current fiscal year. Furthermore, the persistent uncertainty surrounding the global automotive market requires the LISI AUTOMOTIVE division to continue the trend of lowering the break-even point, which has been anticipated since 2023.

With its strengthened financial position, the Group remains confident in its ability to consolidate its position as a global leader in its chosen niche markets. It reaffirms its objective - assuming constant exchange rates and macroeconomic conditions - to improve its key financial indicators, including EBIT, for the fourth consecutive fiscal year and to once again generate positive Free Cash Flow*.

Operational priorities for 2026 include:

 the deployment of capacity resources (“Fasteners” business) and improvements in industrial productivity (“Structural Components” business) to meet rising demand;  continuing the reduction in inventory levels initiated in 2025, particularly for raw materials and work-in-progress, through the acceleration of material flows;  managing delivery priorities to ensure the ramp-up of programs.
