Gerresheimer stock surges 17.77% on Silgan Holdings takeover rumors
Shares in Gerresheimer soared on Friday, jumping 17.77% to close at €20.94. The sudden rise came amid reports of a potential takeover by US firm Silgan Holdings. Despite broader market declines, the packaging specialist's stock defied the downward trend.
The surge follows an informal approach from Silgan Holdings, which has formally expressed interest in acquiring Gerresheimer. While no binding offer has been made, the prospect of a deal has already reshaped how investors value the company. On March 20, 2026, the stock spiked as much as 24% to €22.42 on takeover speculation, rebounding from recent lows tied to accounting concerns and fears of SDAX delisting.
Gerresheimer's shares now lead the SDAX index, buoyed by expectations of sector consolidation. Investors are closely watching the pharmaceutical and healthcare packaging market, where Gerresheimer plays a key role. If Silgan submits a formal bid, shareholders will push for a significant takeover premium.
Meanwhile, the wider market struggled, with the DAX dropping nearly 2% by the end of the week. Since late February, the index has lost over 11%, yet Gerresheimer's stock remained unaffected. Silgan's US shares, however, dipped around 1% on the day the rumors surfaced.
Despite Friday's rally, Gerresheimer's stock is still down 72.75% over the past year. The strategic interest from Silgan has, for now, provided a shield against further declines.
The company's future hinges on whether Silgan submits a concrete offer. Until then, the mere possibility of a deal continues to support Gerresheimer's share price. Analysts will monitor negotiations closely, as any takeover could reshape the packaging sector's competitive landscape.
