Stock market data

An exceptional year

2025 was marked by an outstanding rise in LISI's share price, which closed the financial year at €53.10, compared to approximately €22.00 at end-2024, representing a year-on-year increase of +141.4%. This performance reflects renewed market confidence in the Group's strategy, the strength of its financial fundamentals, and the resilience of its outlook across all its markets.
This remarkable performance came against a broadly favorable market backdrop for the sector, driven by the recovery in global air traffic, the ramp-up of European defense programs, and the momentum observed in high-value-added automotive activities. LISI was able to fully capitalize on this environment, while confirming the relevance of its strategic positioning built on innovation, competitiveness, and industrial specialization.

Strong increase in trading volumes

The sustained trading activity of the stock throughout the year also reflects strong investor interest. The average volume of shares traded rose significantly to 104,010 shares on average, reflecting a meaningful expansion of the active free float and the Group's growing visibility on financial markets.

LISI joins the SBF120

This momentum was supported by several favorable quarterly results, the announcement of new orders in aerospace and defense, robust cash generation, and the announced exit of Peugeot Invest. At the end of the period, the Group was included in the SBF120 and CAC MID60 indices on the Paris Stock Exchange for the first time in its long history as a listed company.
LISI thus ranked among the top performers in the industrial segment of the Paris Stock Exchange in 2025. This trajectory underscores the renewed confidence of investors in the Group's ability to combine profitable growth, financial discipline, and sustainable value creation.
