3U HOLDING AG: Operational improvement after nine months

– Renewable Energies doubles EBITDA

Marburg (pta012/12.11.2026/08:00 UTC+1)

Marburg, 12 November 2026 – 3U HOLDING AG (ISIN DE0005167902; ticker symbol: UUU) significantly improved its operating result in the first nine months of 2026. Group EBITDA rose to EUR 1.7 million, compared with EUR –1.9 million in the prior-year period, and the EBITDA margin to 4.8 %. Group revenue, on the other hand, declined by 14.5 % to EUR 35.4 million (9M 2025: EUR 41.3 million). This was mainly due to the realignment of the HVAC segment. At EUR –5.8 million, the Group net result was almost on a par with the prior-year figure of EUR –5.7 million.

The improvement in earnings was driven primarily by the Renewable Energies and ITC segments. In addition, personnel expenses and other operating expenses decreased. EBITDA includes restructuring expenses of EUR 0.9 million in the HVAC segment, compared with EUR 0.7 million in the previous year. The Group net result did not improve despite the higher EBITDA, mainly because of higher depreciation and amortisation and higher financing costs for the repowering of the Langendorf wind farm in Saxony-Anhalt. Earnings per share remained unchanged at EUR –0.17.

In the third quarter of 2026, EBITDA was negative at EUR –0.4 million (Q3 2025: EUR –1.6 million). This was due to the restructuring expenses and lower wind yields during the low-wind summer months. As at 30 September 2026, the 3U Group had 166.1 employees (FTE; 31 December 2025: 204.5). The decrease is mainly attributable to the restructuring in the HVAC segment. Headcount was also reduced as a result of efficiency measures in the ITC segment and at 3U HOLDING AG.

"We made significant operational progress in the first nine months," says Christoph Hellrung, Chief Financial Officer (CFO) of 3U HOLDING AG. "Group EBITDA is clearly positive, and the Renewable Energies segment more than doubled its EBITDA following the repowering in Langendorf. In the HVAC segment, we made a clear decision by closing down three companies. Going forward, our focus there will be on the online retail business of Selfio SE."

The ITC segment increased its EBITDA by 14.8 % to EUR 2.7 million (9M 2025: EUR 2.4 million), although revenue fell by 7.5 % to EUR 9.4 million. The EBITDA margin improved significantly from 23.5 % to 29.1 %. In terms of revenue, the expansion of high-margin product and service areas was only able to partially offset the structural decline in the traditional voice business. Efficiency measures led to lower personnel expenses.

The Renewable Energies segment benefited from the repowering of the Langendorf wind farm, which was completed on 2 March 2026. The five new, more powerful wind turbines increased the installed capacity of the Group's own wind and solar portfolio from 53 MW to 73 MW. The wind farms generated 56.1 GWh of electricity in the first nine months, compared with 24.1 GWh in the previous year. Segment revenue rose by 75.6 % from EUR 3.6 million to EUR 6.4 million. Segment EBITDA increased by 114.3 % to EUR 5.2 million, compared with EUR 2.4 million in the prior-year period, while the EBITDA margin rose from 67.2 % to 82.0 %.

In the HVAC segment, revenue decreased by 28.1 % from EUR 28.2 million to EUR 20.3 million. In addition to the weakness of the construction sector and subdued demand for modernisation, this reflected the realignment of Selfio SE, which deliberately scaled back less profitable business. Despite the restructuring expenses, segment EBITDA improved slightly from EUR –4.0 million to EUR –3.6 million. However, as revenue fell more sharply, the EBITDA margin deteriorated from –14.3 % to –17.8 %. The implementation of the decision taken in August 2026 to discontinue business operations at Calefa GmbH, EMPUR Produktionsgesellschaft mbH and EM-PLAN GmbH is proceeding as planned. Going forward, the segment will focus on the online retail business of Selfio SE.

As the Bitcoin price had risen by 30 September 2026, the Group recognised a write-up of EUR 9.6 million on its unchanged holding of 427.1 Bitcoin. This almost fully offsets the impairment of around EUR 9.9 million recognised in the first half of the year. For the first nine months, this results in a net non-cash expense of around EUR 0.3 million. Owing to the write-up, the Group net result for the third quarter amounted to EUR 6.8 million, compared with EUR –3.0 million in the prior-year quarter. The carrying amount is therefore almost equal to the acquisition cost.

As at 30 September 2026, total assets increased to EUR 173.2 million (31 December 2025: EUR 158.6 million). Cash and cash equivalents rose from EUR 12.5 million to EUR 27.5 million, and net debt from EUR 49.1 million to EUR 56.1 million. The equity ratio fell from 49.8 % at the end of 2025 to 42.1 %. However, the equity ratio increased again compared with 39.9 % as at 30 June 2026.

Outlook for 2026

The Management Board confirms the guidance for the 2026 financial year, which was adjusted by way of an ad hoc announcement on 21 August 2026. It continues to expect Group revenue of EUR 46 million to EUR 50 million and Group EBITDA of EUR 2.5 million to EUR 4.5 million. Expectations for the ITC and Renewable Energies segments remain unchanged. In the Renewable Energies segment, the fourth quarter is of particular importance following the low-wind summer months. For the HVAC segment, the Management Board still expects revenue of around EUR 26 million and EBITDA of EUR –3.5 million to EUR –4.5 million. The guidance is subject to overall economic and geopolitical developments remaining essentially unchanged. The move to the Scale segment of the Frankfurt Stock Exchange, resolved on 14 October 2026, is expected to be completed before the end of the 2026 financial year.
