Gerresheimer Faces Forced ETF Sell-Off After SDAX Expulsion

Gerresheimer removed from SDAX index after missing audited report deadline, triggering forced selling. Shelly Group replaces it as the firm faces an accounting probe and restructuring.

The formal removal of Gerresheimer from Germany's SDAX index took effect on April 10, triggering an immediate wave of forced selling. Passive index funds and ETFs that track the index are now compelled to dump the pharmaceutical packaging supplier's shares from their portfolios. The beneficiary of this mandated portfolio reshuffling is Bulgaria's Shelly Group, a smart home device manufacturer, which has taken the vacant spot and will see corresponding buying pressure.

This expulsion was a direct consequence of a missing audited annual report. Index rules require members to publish certified financial statements within four months of their fiscal year-end. For Gerresheimer, whose 2024/25 year closed at the end of November, that deadline passed unmet. The delay stems from a deeper accounting crisis, with German financial watchdog BaFin investigating potential bookkeeping errors. An external audit firm is currently scrutinizing business transactions from 2024 and 2025, pushing the earliest possible completion date for the annual report into June.

The operational fallout is severe. The company has postponed its Q1 2026 results and an Annual General Meeting originally scheduled for early June indefinitely. Concurrently, management is negotiating with creditors for deadline extensions to avoid breaching loan covenants. To shore up its financial position, Gerresheimer is implementing a sharp restructuring. It is selling its US subsidiary Centor Inc., which was valued at nearly 300 million euros at the end of 2024. The plan also includes factory closures in the US, with the glass production site in Chicago Heights slated to shut by the end of 2026, shifting output to Italy and India.

Investors have already borne significant losses. The stock plummeted roughly 30% in a single day on February 11 when new details of the accounting issues emerged. By the end of February, expanded BaFin probes had driven the share price to its lowest level since 2009. The stock closed at 17.17 euros on the day of its SDAX exit, marking a year-to-date decline of over 38%. Over a twelve-month period, the shares have shed approximately 68% of their value and now trade about 43% below their 200-day moving average.

The next opportunity for a potential return to the SDAX is the index's regular review on June 3, 2026. This hinges on two critical conditions: the overdue audited financial statements must be submitted by then, and lenders must grant the necessary waivers. If the audit certification slips further into late June, the company will remain locked out of the passive investment flows tied to the German small-cap index, leaving the market without a reliable basis for valuation.
