Gerresheimer stock (DE000A0LD6E6): 59% rally on insider buying

Gerresheimer shares have rallied 59% in the past month amid €9.7M insider purchases and creditor support, though a delayed annual report due in June raises questions about sustainability.

Gerresheimer stock has surged 59% over the past month, climbing from a February low of €15.57 to around €45.19 on BATS Europe, fueled by nearly €9.7 million in insider buying from executives and major shareholders, according to Ad-hoc-News as of May 11, 2026. This rebound follows creditor waivers extending debt maturities into late summer 2026, providing breathing room amid internal investigations that delayed the audited annual report, now expected in June.
