ArcelorMittal Spain Holding absorbs Powders after closing the metal powders plant

ArcelorMittal Spain Holding, S.L.U. will absorb its subsidiary ArcelorMittal Powders, S.L.U., the company through which the steel group attempted to manufacture metal powders for 3D printing in Asturias. The common merger project was signed on October 30, 2026, and is published in the Official Gazette of the Mercantile Registry (Boletín Oficial del Registro Mercantil) number 215, dated November 10, 2026, under reference BORME-C-2026-5881.

The operation falls under the simplified merger regime for wholly-owned subsidiaries provided for in articles 9 and 53 of Royal Decree-Law 5/2023, of June 28 (RDLME), and is published in compliance with article 55. Since the absorbed company is 100% directly owned by the absorbing company, it does not require approval from general meetings nor a report from independent experts. The announcement occupies the second section, for announcements and legal notices, in the mergers and acquisitions department, on pages 7293 to 7300.

The merger extinguishes ArcelorMittal Powders without liquidation and transfers its assets en bloc to the parent company, which is subrogated by universal succession to all its rights and obligations. The merger balance sheets were closed on September 30, 2026, and the accounting effects are retroactive to January 1 of the same fiscal year.

A failed prototype and the abandonment of additive manufacturing

Until 2025, the group’s additive manufacturing activities in Spain were divided between two wholly-owned subsidiaries of ArcelorMittal Spain Holding: ArcelorMittal Investigación, Innovación e Inversión, S.L.U., focused on R&D regarding new metal powders and the optimization of 3D printing processes, and ArcelorMittal Powders, S.L.U., which made a significant investment in an experimental atomizer prototype to supply raw materials to additive printing manufacturers. After more than two years of testing, the development proved unsuccessful, and the quality and prices demanded by the market were not achieved.

At the beginning of 2026, the group decided to halt the tests due to the accumulation of costs over the last two fiscal years and the uncertainty of achieving technical results within a period of less than twelve months. The experimental equipment, the company’s only asset, was sold for its residual value. The parent company had hired the prototype operators in 2021, who were gradually incorporated into the payroll of ArcelorMittal Powders.

A previous ERE with the termination of most of the workforce

The closure of the activity led to the opening of an employment regulation proceeding in which an agreement was reached for the termination of the employment relationships of most of the workers, with the support of ArcelorMittal Spain Holding. The document specifies that the merger itself “will have no effect on employment”: the absorbed entity retains a single worker, who is transferred to the parent company by business succession in accordance with Article 44 of Royal Legislative Decree 2/2015, of October 23, which approves the Workers’ Statute.

The parent company maintains that the joint management of research and operational personnel allowed for the rationalization of the exit “with the lowest possible global cost” for its Spanish subsidiaries. Some of the researchers have moved to new invested entities in which ArcelorMittal Investigación, Innovación e Inversión has contributed, through non-monetary contributions, the results of its ongoing research, mainly algorithms, through minority stakes in joint ventures.

Creditors, calendar, and shareholders’ rights

• The creditors of ArcelorMittal Powders become creditors of the absorbing company; no additional personal or real guarantees have been presented.

• Shareholders representing at least 1% of the capital may demand the holding of the absorbing company’s general meeting within one month from the publication.
• Formalization by public deed is scheduled for December 15, 2026, with registration in the mercantile registries of Madrid and Asturias.

Two companies and one single decision table

• Absorbing entity: ArcelorMittal Spain Holding, S.L.U., domiciled at carretera de Toledo, km 9.2, 28021 Villaverde (Madrid); registered in the Mercantile Registry of Madrid, volume 20,517, folio 115, page M-363161, CIF B-58597949.
• Absorbed entity: ArcelorMittal Powders, S.L.U., domiciled at Residencia La Granda s/n, 33418 Gozón (Asturias); registered in the Mercantile Registry of Asturias, volume 4511, folio 190, page AS-59895, CIF B72477136.
• Signature: the project was signed by the administrators of both companies on October 30, 2026, and the announcement was signed in Madrid, on November 5, 2026, by the non-director secretary of both, Javier Serra Callejo.

The merger closes the chapter on the group’s bet on additive manufacturing in Spain and concentrates any future results of the knowledge generated by ArcelorMittal Powders within the parent company. For Asturian industrial employment, the announcement certifies a process already completed: activity ceased before the corporate operation, which is part of a global group project to reduce the number of companies. The subsidiary’s creditors now depend on a company domiciled in Madrid, without new guarantees and with the balance sheets closed as of September 2026 as a reference.
