Gerresheimer’s €10M Insider Bet Counters a Regulator’s Leasing Probe and a 60% Stock Wipeout
Published on 05/15/2026 at 04:51 | Redaktion boerse-global.de
The strongest vote of confidence in Gerresheimer right now comes from its own corner office — but that support lands against a backdrop of mounting regulatory scrutiny and a persistent short seller siege. In the first week of May, AOC Gecko, an entity tied to major shareholder Active Ownership, scooped up nearly 287,000 shares at an average price of around €25 each, pushing the total outlay to almost €10 million. The buying spree, which positions Active Ownership with a stake well in excess of 15%, tops Germany’s insider transaction rankings for the period. Yet the very same weeks have seen Germany’s financial regulator, BaFin, dig into the company’s books over apparent accounting mismanagement tied to the Bormioli acquisition — a probe that has kept short interest near 11% and the stock 60% below its 52-week high of over €64.
BaFin’s investigation, launched in March, centres on an interim consolidated statement. The regulator is scrutinising allegedly misstated leasing liabilities, incorrect useful-life assumptions for capitalised development costs, and questionable impairment charges within the Advanced Technologies segment, which carried a book value of nearly €197 million. These issues compound earlier revelations from late 2025, when Gerresheimer acknowledged systemic booking errors on bill-and-hold contracts — a mistake that forced it to flag potential impairment charges of up to €240 million. The combined effect has delayed the release of the audited 2025 annual report, leaving the company’s financial integrity in question.
To buy breathing room, Gerresheimer has leaned on its creditors. Holders of Schuldschein loans worth €870 million agreed to extend repayment terms to September 2026, and key leverage covenants have been temporarily suspended. Meanwhile, the group is accelerating asset sales: Morgan Stanley has been mandated to find a buyer for the U.S. subsidiary Centor, a move that should close this year. The proceeds will help fund the closure of the Chicago Heights plant and the migration of production capacity to Italy and India. Management has stood by its 2026 guidance, forecasting revenue of up to €2.4 billion and an adjusted operating margin of roughly 18%.
Should investors sell immediately? Or is it worth buying Gerresheimer?
On the trading floor, the insider buying has injected some life into a stock that had been crushed. Gerresheimer shares have climbed roughly 43% over the past month, recently hovering at €25.20 to €25.30 — though a 4.5% pullback on Thursday trimmed some of those gains. Hedge funds continue to hold substantial short positions; Arrowstreet Capital has made only marginal adjustments to its bet against the company. The elevated short interest, currently at 11% of reportable shares, means the stock remains vulnerable to a sharp squeeze if the next major update goes smoothly — or to a fresh rout if it doesn’t.
That next inflection point arrives in June, when Gerresheimer finally plans to publish its audited 2025 accounts. A clean audit could trigger a wave of short covering, while any further accounting missteps would swiftly erase the recent rally. The half-year financial report, due on July 14, 2026, will then test whether the underlying business can deliver on the promised margin and revenue recovery. For now, Active Ownership’s €10 million wager suggests those closest to the company see value — but the path ahead is lined with regulatory tripwires.
