Consolidated HALF-YEAR RESULTS

In accordance with IFRS 5 “Non-current assets held for sale and discontinued operations”, the discontinued operations are identified in a separate line in the financial statements for the first half of financial year 2024-2025 and for the first half of financial year 2023-2024 for comparison purposes.

Revenue for the first half of financial year 2024-2025 of the continuing operations totalled €7.55M, a 10% increase compared with the same period of last financial year (from April 1 to September 30, 2023). The manufacturing activities have generated €6M of revenue stable compared to the same period of last year. Engineering activities, dedicated to the development and the industrialization of future customized MEMS products, accounted for €1.5M in the first half of financial year 2024-2025 (versus €0.8M in the first half of financial year 2023-2024). That growth is mainly related to inertial projects on the Magelan platform.

Consolidated operating income from the continuing operations for the first half of financial year 2024-2025 amounted to +€0.88M compared to +€0.64M. This improvement is mainly due to the increase in revenue and improved operational performance.

After recognition of a negative financial result of €(0.26)M, the consolidated net income amounted to €0.6M.

Discontinued operations

No result has been generated during the first half of the year. The liquidation of the legal entity Tronics Mems Inc has been postponed to 2025.

BALANCE-SHEET STRUCTURE

As of September 30, 2024, Tronics' equity amounted to €(5.6)M. Cash amounted to €0.1M and gross debt to €11.6M, mainly related to the debt towards TDK Electronics AG.

OUTLOOK

In the second half of financial year 2024-2025, Tronics expects a decrease of its revenue compared to the first half of financial year 2024-2025, but an overall growth of its annual revenue compared to financial year 2023-2024. Tronics will remain focused on the ramp-up of the existing product portfolio and new product launches, which will allow for increased sales of innovative MEMS products for high value-added inertial and industrial applications.
