Nabaltec AG: Dirk A. Müller succeeds Günther Spitzer as the new Chief Financial Officer; CEO's contract extended by five years

Schwandorf, 17 March 2026 – Nabaltec AG has announced a change in its Management Board. Günther Spitzer, who has been a member of Nabaltec AG's three-member Management Board as Chief Financial Officer (CFO) since 2017, will not extend his contract, which expires on 31 December 2026, and will retire at his own request after nearly 45 years with the company.

The Supervisory Board has therefore appointed Mr. Dirk A. Müller to the Management Board with a contractual term of four years as of 1 December 2026. "With Dirk A. Müller, Nabaltec has gained a financial manager with many years of experience in management positions and extensive expertise in financial management, capital market processes and corporate organization," said Johannes Heckmann, CEO of Nabaltec AG. "Through his work on Nabaltec's Supervisory Board, Mr. Müller already knows our company, our structures and our business processes very well. This familiarity will enable a quick and smooth transition to the role of CFO and will provide valuable impetus for the further development of Nabaltec."

Dirk A. Müller studied business administration in Münster and started his career at Ernst & Young (EY) in Düsseldorf, including a two-year assignment in Boston. After six years, he moved to Jackstädt GmbH as Head of Accounting and Tax before returning to EY in 1999, where he became a partner in the Equity Capital Markets/Transaction Services Division in 2002. in 2003, he took over responsibility for finance, controlling, taxes, investor relations, IT and logistics as Managing Director and CFO at A.T.U in Weiden. He was then CFO of SiC Processing GmbH and later Group CFO of the Onlineprinters Group. Dirk A. Müller has been Group CFO of the Cologne-based Swash Group since September 2024. He is an auditor, tax consultant and CPA. He has been a member of the Supervisory Board of Nabaltec AG since 2024 and holds no further positions on any other supervisory body. He will step down from the Supervisory Board on 30 November 2026.

As Chief Financial Officer, Dirk A. Müller will assume sole responsibility for Finance/Controlling, Administration and Information Technology from 1 January 2027. Until this date, the Management Board of Nabaltec AG will act as a four-member board for a short transitional period.

In addition, the Management Board contract of Johannes Heckmann, CEO of Nabaltec AG, was extended by five years. Nabaltec's Supervisory Board is thus sending another clear signal of stability and continuity in the company's management, underscoring its confidence in the company's successful strategic direction.

“The Supervisory Board has accepted Mr. Günther Spitzer's decision with great regret. Mr. Spitzer has made a significant contribution to Nabaltec's development in nearly 45 years with the company - as a true home-grown talent - with a high level of expertise, reliability and great personal commitment," explained Gerhard Witzany, Chairman of the Supervisory Board. "We would like to expressly thank him for the extraordinarily long, trustworthy and always very good collaboration."
