Shares of Partners Group plunged 9.0% to CHF 681.80 on September 1, 2026, after the Swiss private markets giant reported a sharp drop in half-year earnings and announced that CEO David Layton would step down — a double blow that crystallizes mounting investor anxiety about the firm's direction. Partners Group Loses Its CEO and 13% of Its Profits — Is the Private Markets Giant's Growth Model Starting to Crack?

Shares of Partners Group cratered 9.0% to CHF 681.80 on September 1 after the Swiss private markets firm delivered a bruising half-year report: profit fell 13% to CHF 502 million, CEO David Layton announced his departure, and the overhang from a summer of investor withdrawals in open-ended funds continued to weigh on sentiment. For a company that had been one of Europe's most reliable asset-management growth stories, the combination landed like a verdict.

• Performance Fees Collapsed, Dragging the Entire Profit Line Down

Management income rose 12% in constant currency to CHF 905 million, but performance income — the lucrative share of profits Partners Group earns when it sells investments at a gain — dropped 39% to CHF 216 million, comprising just 19% of total revenue.

The firm now guides for performance income at roughly 20–25% of revenues for full-year 2026 , well below its own long-term target of 25–40%, partly because strong 2025 exit activity pulled deals forward. Until exit markets reopen more broadly, the high-margin fee line that turbocharged past earnings will remain muted.

• Open-Ended Fund Withdrawals Turned Into an Industry Headline

Partners Group gated its $8.6 billion flagship evergreen fund after redemption requests hit 9.8% of net asset value — nearly double the 5% quarterly cap.

Across the platform, evergreen redemptions reached $3.8 billion in the first half, with gates activated on five funds total.

Management warned the evergreen drag could slow overall asset growth by 1–2 percentage points in both late 2026 and 2027.

• The CEO Switch Adds Uncertainty at a Delicate Moment

Layton will become chief investment officer from January 1, with Roberto Cagnati and Juri Jenkner appointed co-CEOs. While the firm frames this as a planned rotation, the timing — amid gating headlines and sliding profits — raises the stakes. Layton joined in 2005 and became sole CEO in 2021; historically, Partners Group CEOs serve about eight years.

• Record Fundraising Offers a Counterpoint — For Now

Assets under management rose 7% year-on-year to $186 billion, and record new client commitments reached $16 billion, up from $12.2 billion a year earlier. That institutional demand proves the brand retains pull. But if redemption pressures persist, net growth will shrink even as gross inflows hold. Investors now face a simple question: can two new leaders stabilize a business model caught between record capital-raising and rising liquidity risk?
