3U HOLDING AG: closure of three companies in the HVAC segment approved – forecast for financial year 2026 adjusted

Marburg (pta008/21.08.2026/11:35 UTC+2)

Marburg, 21 August 2026 – 3U HOLDING AG (ISIN DE0005167902; ticker: UUU) is completely and permanently closing down the business operations of its group companies Calefa GmbH, EMPUR Produktionsgesellschaft mbH and EM-PLAN GmbH in the HVAC segment. The resolutions of the managing directors were passed today; the Management Board and the Supervisory Board of 3U HOLDING AG have given their approval. The decision is final and is not subject to any condition. Operating activities will be discontinued as of 30 November 2026; the final closure is expected to take effect on 31 March 2027. A total of 47 employees are affected. The remaining activities of the HVAC segment, in particular online retail, are not affected by the resolutions.

The reasons are the structural decline in demand for surface heating and the persistent weakness of the construction sector. For Calefa GmbH and EMPUR Produktionsgesellschaft mbH combined, the Management Board expects negative EBITDA of more than EUR 1.0 million for financial year 2026, compared with a planned figure of around EUR 0.1 million; EM-PLAN GmbH performs its services predominantly for these two companies and will lose the basis for its operations upon their closure. In the Management Board's assessment, there is no viable concept for continuing the business operations.

For financial year 2026, the Management Board expects restructuring expenses of EUR 1.0 million to EUR 1.5 million to arise from the closures. In addition, there will be non-cash impairment losses on the assets of these companies.

Against this background, the Management Board is adjusting the forecast for financial year 2026 published on 29 July 2026. It now expects Group revenue of EUR 46 million to EUR 50 million (forecast of 29 July 2026: EUR 48 million to EUR 53 million) and Group EBITDA of EUR 2.5 million to EUR 4.5 million (forecast of 29 July 2026: EUR 4 million to EUR 6 million).

In the HVAC segment, the Management Board now expects revenue of around EUR 26 million (previously: around EUR 28 million) and EBITDA of minus EUR 3.5 million to minus EUR 4.5 million (previously: minus EUR 2.0 million to minus EUR 3.0 million). For the ITC and Renewable Energies segments, expectations remain unchanged.

The complete integration of the EMPUR group presented in the 2026 half-year financial report will therefore not be continued; going forward, the HVAC segment will focus on the online retail of sanitary, heating and air-conditioning products.
