Summary
Activist investor Saba Capital Management has moved to seize control of Impax Environmental Markets through a formal board requisition, leveraging a 29.9% stake acquired via the company's exit tender offer. The London-listed investment company now faces shareholder pressure to replace its entire board with directors aligned to Saba's strategic vision.
In a letter dated 20 April 2026 addressed to IEM's board, Saba outlined its intention to requisition a general meeting where shareholders will vote on the removal of all incumbent directors. The firm stated that the new board would comprise solely of qualified, independent directors committed to delivering long-term shareholder value. This represents an escalation of Saba's campaign against the current management structure, occurring just days after the completion of IEM's exit tender offer process that established Saba as the largest shareholder.
The activist's case rests on significant performance underperformance. Over the past five years, IEM's share price has returned -3.3%, a stark divergence from its MSCI ACWI Index benchmark, which posted +72.4% returns over the same period—a cumulative 75 percentage point lag. Saba has characterized the incumbent board's tenure as marked by an inability to execute necessary strategic changes that would improve operational and financial performance.
The formal requisition documents are expected to be filed imminently, initiating the procedural steps required to convene a shareholder meeting. The scale of Saba's stake—approaching 30% of outstanding shares—provides substantial leverage in the proxy contest, though the outcome will ultimately depend on voting by other shareholders and the company's regulatory governance framework for such requisitions.
