Activist Tremors: GAM Shakes Up UK Asset Management with Liontrust Stake

LONDON, UK – July 14, 2026

The simmering tensions within the UK's embattled asset management sector have boiled over into public view. In a move signaling a sharp escalation of shareholder activism, GAM's special situations managers, Albert Saporta and Randel Freeman, have declared a stake of over 5% in Liontrust Asset Management PLC. The announcement, which follows a contentious open letter in March, is a direct challenge to Liontrust's leadership and strategy. Simultaneously, the duo revealed a new 2.2% position in sustainability-focused Impax Asset Management, branding both firms as deeply undervalued and ripe for a shake-up.

This two-pronged assault is more than just a boardroom drama; it's a stark reflection of the immense pressures squeezing the UK's mid-sized fund managers. With declining assets, plunging share prices, and a relentless consolidation wave, GAM's activist playbook may be the opening chapter of a much larger story of forced transformation in a sector struggling to find its footing.

The Gauntlet Thrown Down at Liontrust

GAM's public criticism of Liontrust is unflinching. The press release from Saporta and Freeman’s team reiterates their March assertion that management has presided over a “value destruction enterprise.” The numbers, drawn from public records, paint a grim picture. Since its peak in 2021, Liontrust’s stock has cratered by over 80%, while its assets under management (AUM) have been nearly halved, falling from a high of £42.3 billion to a recent figure of approximately £21.4 billion.

For GAM’s managers, the blame lies squarely with strategic missteps and a perceived disconnect between executive compensation and shareholder returns. They previously highlighted the CEO’s compensation package, which totaled roughly £17 million over five years, as unconscionable for a firm experiencing such a precipitous decline. The letter sent in March bluntly stated that management had “failed to deliver shareholder value over the last few years” through a series of “wrong strategic choices.”

Liontrust's board has pushed back against this narrative. In response to the initial activist pressure, the company affirmed its commitment to “clear strategic objectives” designed to deliver long-term value. It pointed to the recent acquisition of River Global’s asset management business as a step toward diversifying its product range and enhancing future earnings. The board also highlighted its resilient performance in a difficult market, citing a share buyback program, strong capital reserves, and new institutional mandates as signs of underlying strength. However, for GAM’s team, these moves are “way too little too late,” a minor course correction when a fundamental strategic overhaul is needed.

A Sector Under Siege: Consolidation and the Hunt for Value

GAM's targeting of Liontrust and Impax is not happening in a vacuum. It is a calculated move within a UK asset management industry facing a perfect storm of challenges. Intense M&A activity has become the new norm, driven by the relentless pressure to gain scale. Rising regulatory costs, the need for significant technology investment, and fierce fee compression from low-cost passive funds are forcing firms to either grow or be acquired.

Recent blockbuster deals, such as Nuveen's acquisition of a division of Schroders and NatWest's purchase of Evelyn Partners, underscore the trend. The market is increasingly bifurcating between massive, diversified players who can leverage scale and niche, specialist boutiques with unique offerings. Mid-sized firms like Liontrust, which lack the heft of the giants and a sufficiently differentiated focus, are caught in the “squeezed middle” and are becoming prime targets.

Activist investors like Saporta and Freeman thrive in this environment. They hunt for companies whose market valuation has become detached from their intrinsic potential, often due to perceived management failures or an inability to adapt. By taking a significant stake and publicly agitating for change—be it a strategic review, cost-cutting, or an outright sale—they aim to force the board’s hand and unlock that trapped value for shareholders. The liquidation of a record number of UK investment trusts in 2025, often under activist pressure, demonstrates the effectiveness of this strategy in the current climate.

The Sustainability Paradox and the Impax Opportunity

The investment in Impax Asset Management adds another fascinating layer to GAM’s strategy, highlighting a key paradox in modern finance. Impax, a pioneer in sustainability-focused investing, has seen its share price collapse by roughly 90% from its 2021 high, with AUM falling 42% in the same period. The market has punished the firm as investor appetite for ESG-themed funds cooled amid broader economic turbulence.

Yet, GAM’s managers see this downturn not as a failure but as a temporary dislocation. They argue that Impax is “extremely undervalued,” trading at just 0.31% of its AUM after accounting for its substantial cash reserves. In their view, the company’s deep expertise in sustainability, which has been a “liability in the recent past, represents… a valuable asset.”

This perspective is forward-looking. While short-term flows have been volatile, the long-term structural trend towards sustainable investing is undeniable. The UK ESG market is projected to more than double by 2034, driven by both investor demand and a wave of new regulations from the Financial Conduct Authority (FCA). For a larger asset manager without a strong ESG franchise, acquiring a specialist like Impax could be a powerful strategic shortcut. GAM is betting that Impax’s green credentials will make it a prime “target in the consolidation of the UK fund management industry,” transforming its current weakness into a highly coveted strength.

A Pattern of Engagement: The Activist Playbook

The challenge to Liontrust and Impax is not an impulsive act but a deliberate execution of a well-honed strategy by Albert Saporta and Randel Freeman. With over 70 years of combined experience in global special situations, their GAM-managed portfolios are designed to capitalize on complex corporate events and significant change. Their track record reveals a pattern of assertive engagement to protect shareholder interests.

Previous campaigns include challenging the terms of a tender offer for Japanese auto-parts maker Yutaka Giken, where they took their case to a Japanese court, and publicly urging SBI Holdings to provide greater transparency around its cryptocurrency assets to maximize shareholder value. This history suggests their engagement with Liontrust and Impax will be persistent and methodical.

By publicly building their stakes and articulating their thesis, Saporta and Freeman have fired a clear warning shot. They have not only put the management teams of two prominent UK firms on notice but have also cast a spotlight on the vulnerabilities and opportunities coursing through an entire industry in transition. For the boards of Liontrust and Impax, the pressure to deliver a convincing response is now immense.
