Summary
Saba Capital Management has secured control of Impax Environmental Markets following a requisitioned general meeting held on 17 June 2026. The activist hedge fund successfully replaced the entire board, with five independent directors not re-elected and four Saba-nominated candidates appointed in their place. The meeting achieved a 44% shareholder turnout, sufficient to execute the governance overhaul despite Saba holding only a minority position in the investment trust.
The takeover outcome aligns with Saba's stated strategy. In a February 2026 statement, the firm signaled its intention to requisition a general meeting to remove IEM's existing board and appoint replacement directors. The company's own board subsequently acknowledged "the likelihood of Saba having effective control of the company" following completion of shareholder exit activity. This represents a case study in activist pressure tactics within the UK regulatory environment, where a minority shareholder leveraged favorable governance rules and deteriorating operational performance to engineer board replacement.
IEM's operational underperformance provided Saba with substantive grounds for intervention. On a three-year basis, IEM's share price returned 7.5%, lagging its benchmark by more than 51 percentage points (benchmark return: 58.8%). This dramatic underperformance, combined with significant shareholder base erosion—with investors selling 78% of trust shares in recent months—created conditions where Saba's nominees could secure sufficient votes to effect the transition.
The board transition follows a similar Saba victory at another FTSE 250 entity, establishing the fund as an active player in UK-listed investment vehicle governance. According to available reporting, Saba is targeting board placements at a third FTSE 250 company, suggesting the activist campaign will continue expanding across the sector. The IEM outcome demonstrates how activist investors can exert control through minority shareholdings when operational performance falters and shareholder composition shifts significantly.
