## Ancora Holdings – H.B. Fuller / Advanced Medical Solutions Activist Campaign (2026)
### Overview
Activist investor Ancora Holdings Group is reportedly pushing US adhesives maker H.B. Fuller Co. to abandon a proposed takeover of UK-based Advanced Medical Solutions Group Plc (AMS) (Bloomberg, May 26).
### Key Parties
- **Ancora Holdings Group**: Cleveland-based activist investor known for campaigns against industrial and specialty chemical companies.
- **H.B. Fuller Co.**: US-based adhesives manufacturer (NYSE: FUL); a mid-cap specialty chemicals company.
- **Advanced Medical Solutions Group Plc (AMS)**: UK-listed medical device and wound care company.
### Activist Campaign Details
- Ancora is reportedly pushing H.B. Fuller to drop the AMS acquisition bid (Bloomberg, May 26).
- The specific objections—whether valuation, strategic fit, financing, or capital allocation—have not been fully disclosed (Bloomberg, May 26).
### Strategic Context
Cross-border M&A in specialty chemicals and medical devices has faced increased activist scrutiny in 2025–2026, as acquirers are challenged on premium justification and integration risk. Ancora has a track record of targeting mid-cap industrials where it perceives M&A as value-destructive.
### Legal & Regulatory Considerations
- H.B. Fuller's board has fiduciary duties to evaluate Ancora's position; a public campaign may trigger proxy contest mechanics if the acquisition proceeds.
- UK Takeover Panel rules govern AMS's position in any contested or abandoned offer scenario.
- Ancora's campaign may require disclosure of its ownership stake under Section 13(d) thresholds.
### Outlook
Watch for H.B. Fuller board response, any revised or withdrawn bid, and Ancora's escalation tactics including public letters, proxy solicitation, or board nominations.
