Altech Advanced Materials AG - Preliminary annual results as at 31.12.2025

Heidelberg - Altech Advanced Materials AG ("AAM / the Company") (ISIN: ) closed its 2025 financial year with an expected net loss (separate financial statements in accordance with the German Commercial Code) of EUR 4,327 thousand (previous year: EUR 840 thousand).

The preliminary annual result includes other operating income of EUR 161 thousand (previous year: EUR 193 thousand) and personnel expenses of EUR 175 thousand (previous year: EUR 408 thousand), other operating expenses of EUR 367 thousand (previous year: EUR 679 thousand) and depreciation and amortisation of financial assets of EUR 3,870 thousand (previous year: EUR 0 thousand). The financial result amounted to EUR -76 thousand (previous year: EUR -40 thousand).

Other operating expenses mainly consist of costs for capital market listing and communication (EUR 113 thousand), legal advice (EUR 72 thousand), Supervisory Board remuneration (EUR 63 thousand) and financial statement/audit costs (EUR 46 thousand).

Depreciation on financial assets of EUR 3,870 thousand resulted from the lower closing price of AUD 0.026 per share in Altech Batteries Ltd., Australia, on 31 December 2025. The company uses the so-called 10-20 rule to determine the lower fair value of fixed assets in order to assess whether the closing price on the balance sheet date has remained permanently below the acquisition price or book value:

1. if, in the six months preceding the balance sheet date, the market price of the security or the net asset value of the fund unit is permanently more than 20% below the book value, the impairment is considered permanent;
2. The same applies if the volume-weighted average value of the daily market price or net asset value has been more than 10% below the book value over the last twelve months.

Even though, according to the 10-20 rule, there was no need to write down the shares held in Altech Batteries Ltd., Australia, the Management Board decided to write down the shares to the lower market price for reasons of caution due to the price development and the capital requirements still existing at Altech Batteries Ltd. to finance the two projects CERENERGY and Silumina Anodes.

The preliminary balance sheet as at 31 December 2025 in accordance with the German Commercial Code (HGB) shows equity of EUR 4,462 thousand (previous year: EUR 8,790 thousand).

In its latest forecast for 2025, the Management Board anticipated a loss of between EUR 2.5 and 3.0 million (see publication dated 29 August 2025). This estimate was missed by around EUR 0.9 million mainly due to write-downs of EUR 3.9 million on the shares held in Altech Batteries Ltd., Australia, which led to additional expenses of around EUR 2.0 million compared to the last forecast.

The preliminary result stated are based on the preliminary assessment of the 2025 financial year carried out by the Management Board on 9 January 2026. The figures stated in this announcement are subject to the final preparation of the annual financial statements, the audit and the approval of the annual financial statements by the Supervisory Board.
