On March 4, 2026, Wallbox N.V. (the “Company” or “Wallbox”) released information regarding its results of operations for the three months and full year ended December 31, 2025.

WALLBOX N.V. FULL YEAR 2025 RESULTS
 

WALLBOX N.V. FOURTH QUARTER 2025 RESULTS

Definitions and Basis of Presentation

On December 1, 2025, the Company reported on Form 6-K that it had reached a non-binding commercial agreement with its core banking partners and major shareholders regarding a contemplated renewal of its capital structure. As there disclosed, the contemplated transaction includes, among other matters, an extension of existing debt maturities and a proposed liquidity injection through a combination of debt and equity financing, with the objective of establishing a sustainable long-term capital structure.

The Company continues to advance negotiations with its principal lenders and key shareholders and expects to finalize the agreement on the renewed capital structure during the course of March 2026. As part of this process and as previously disclosed on December 1, 2025, the Company and certain of its subsidiaries submitted the corresponding formal communication to the competent Spanish court initiating negotiations with their creditors in order to facilitate the execution of a Spanish restructuring plan. On March 4, 2026, the court authorized an extension of the negotiation period for up to additional three months. The extension has been requested as a procedural measure to ensure sufficient time to complete the negotiations and implement the contemplated transaction. The Company currently expects, however, to finalize the negotiations on the renewed capital structure during the course of March 2026 and file the restructuring plan immediaty thereafter before the Spanish Courts in accordance with applicable law.

In the same context, the Company and certain of its subsidiaries have agreed with the majority of their banking lenders to further extend the standstill agreement dated October 9, 2025 (the “Agreement”). As previously disclosed in the Company’s Forms 6-K filed on October 10, 2025 and November 12, 2025, the Agreement was initially entered into with Banco Santander, S.A., Banco Bilbao Vizcaya Argentaria, S.A., and CaixaBank, S.A., and was subsequently acceded to by Instituto de Crédito Oficial E.P.E., Institut Català de Finances, Mora Banc Grup, S.A., EBN Banco de Negocios, S.A., and Compañía Española de Financiación del Desarrollo, COFIDES, S.A., S.M.E. (collectively, the “Participating Lenders”). The Agreement had previously been extended through January 31, 2026 and March 1, 2026. The Participating Lenders have now agreed to further extend the term of the Agreement through March 31, 2026, with all other terms remaining in full force and effect to facilitate the completion of the negotiations and the filing of the restructuring plan, expected to occur in March 2026.
