LISI Reports Record Results in 2025 with a 63% Increase in Operating Income
In 2025, LISI Group recorded a record revenue of 1,747.9 million euros, up 8.7% year-on-year. This performance is accompanied by a significant improvement in operational profitability, driven by the strength of the aerospace sector and the divestiture of its medical division.
Sustained Organic Growth
LISI Group demonstrated organic growth exceeding 10% for the fourth consecutive year in 2025. The consolidated revenue reached 1,747.9 million euros, up 8.7% compared to 2024, reflecting a notable acceleration across all aerospace market segments. The current operating income stood at 161.0 million euros, up 63.2% from the previous year, while the current operating margin improved by 3.1 points to reach 9.2%. This improvement was fueled by a strong volume effect in the aerospace branch, increased industrial productivity, and the pass-through of inflation in sales prices to customers.
Robust Financial Performance
The operating Free Cash Flow was positive at 56.1 million euros after net industrial investments of nearly 100 million euros, evenly distributed between the group's two divisions. The current gross operating surplus increased by 42.5% to 261.5 million euros, while the self-financing capacity reached 198.3 million euros. Net financial debt significantly decreased to 233.7 million euros, or 0.9 times EBITDA compared to 2.3 times as of December 31, 2024, thanks in particular to the early repayment of loans enabled by the sale of the LISI MEDICAL division. The debt-to-equity ratio dropped to 21.4% from 48.6% a year earlier. The net income amounted to 139.7 million euros, representing 8.0% of the revenue, a 2.5-fold increase from 2024.
Strategic Divestiture and Market Recognition
The group sold its entire LISI MEDICAL division to the American investment fund SK CAPITAL on October 31, 2025, for a net price of 270.4 million euros. LISI reinvested 9.988% of the capital in the holding company that includes the acquired entity, valued at 18.1 million euros. The contract also includes additional price elements that could reach up to 20 million euros depending on investment performance. Furthermore, since December 22, 2025, LISI Group has been included in the SBF 120 and CAC Mid 60 indices of Euronext Paris, marking a new milestone as a listed company.
