(Sharecast News) - Gerresheimer said on Wednesday that it would delay publication of its 2025 annual results until June after an ongoing investigation into business transactions extended longer than expected, a move that would likely result in the company's removal from Germany's SDAX.

The Düsseldorf-based maker of pharmaceutical packaging and medical products said it would not publish its audited annual and consolidated financial statements by the 31 March deadline after consulting with its auditor.

The delay stemmed from a probe by a second external auditing firm into business transactions during the 2024 and 2025 financial years, which had slowed preparation of documentation required for the audit, the company said in a regulatory disclosure.

Gerresheimer said its management board now aimed to publish the audited results in June.

The postponement was expected to trigger the company's exclusion from the SDAX index maintained by Deutsche Börse.

It would also push back other elements of the company's financial calendar.

Gerresheimer said the publication of its first-quarter 2026 trading update, originally scheduled for 16 April, would be postponed, while its annual general meeting planned for 3 June would also be rescheduled.

The company added that it had started discussions with creditors to secure extensions to reporting deadlines contained in its financing agreements, reflecting potential covenant implications from the delayed accounts.

The disclosure followed growing scrutiny of the company's accounting practices.

According to Reuters, Germany's financial watchdog the Federal Financial Supervisory Authority had launched an audit of Gerresheimer's interim financial statements covering the period from 1 December 2024 to 31 May 2025 and expanded other ad-hoc examinations after identifying "concrete evidence" of possible accounting violations.

The uncertainty had weighed heavily on the company's shares.

Reuters reported the stock had fallen about 28% so far this year after plunging roughly 61% in 2025, while Investing.com said the shares dropped more than 8% following the latest announcement.

At 1244 CET (1144 GMT), shares in Gerresheimer AG were down 5.45% at €18.72.
