The Annual General Meeting of Shareholders will be notified during an Extraordinary Meeting of Shareholders to be held on 12 November 2025 in Roermond.

Member of the Executive Board and COO

The Supervisory Board gives notice of its intention to appoint Pepijn Timmermans as a member of the Executive Board, starting 1 December 2025. He will be the new COO of the company, lifting the position of COO to Executive Board level. Frank Kevenaar, the present COO and member of the Management Team of Sif will dedicate all his efforts to the rampup of the new manufacturing plant at Maasvlakte 2 Rotterdam as the Executive Advisor Operations.

Pepijn Timmermans (1973, Dutch nationality) currently is COO at VDL Bus Valkenswaard B.V. Before being appointed at VDL Bus in 2024, he held senior positions from 2013 to 2024 at VDL Nedcar in supply chain management and information technology.

Prior to this, he co-founded and served as managing director at Schleifenbauer Products, a manufacturer of intelligent power distribution units for data centers, and at Atos Origin as program manager. Pepijn Timmermans holds a Master of Science degree in European Automotive Engineering from the University of Hertfordshire and a Bachelor in Automotive Engineering from HAN University of Applied Sciences. Pepijn does not own shares in Sif Holding N.V.

Fred van Beers, CEO: "With the expansion of our Maasvlakte 2 plant, responsibilities for manufacturing, logistics and information technology have increased and justify a representation at Executive Board level. I'm delighted that the Supervisory Board has selected a seasoned manufacturing and information technology professional to join Sif and to assume end-responsibility for these functions. Pepijn will build on the work our present COO Frank Kevenaar has done and it allows Frank to dedicate all his energy to the ramp-up of our new manufacturing plant at Maasvlakte."

An extended resume of Pepijn Timmermans will be available at the Company's offices from 1 October 2025 and will be attached to the Notice of the Extraordinary General Meeting of Shareholders that will be published on 1 October 2025.
