Partners Group Escalates Legal Fight Against Grizzly Research While Tightening Portfolio Rules

Swiss PE firm Partners Group recovers 9% from trough after Grizzly Research attack; launches lawsuit and adopts more selective investing in sensitive sectors.

The Swiss private equity firm Partners Group has seen its shares claw back roughly nine percent from a March trough, yet the stock remains under heavy pressure—trading near 938 euros, down about 23 percent from its August 2025 peak and 14 percent lower year-to-date. The recovery has been fueled by two parallel responses to a devastating short-seller attack in late April: a formal lawsuit and a strategic pivot toward more cautious investing in socially sensitive sectors.

In late April, US-based Grizzly Research published allegations against Partners Group, including an explicit comparison with the collapsed payments company Wirecard. The accusations sent the stock tumbling, but the company has now struck back. Board chairman Steffen Meister confirmed to the NZZ am Sonntag that legal proceedings have been initiated against the short seller, branding the claims as "defamatory and misleading."

The firm's portfolio, which controls more than 150 businesses and has deployed over $260 billion since inception, is also undergoing a strategic refinement. Partners Group will now invest more cautiously in what it calls "socially exposed areas"—a move prompted partly by reputational risks highlighted during the Grizzly episode. Management has acknowledged that in normal market conditions, five to ten percent of its holdings can be expected to face operational difficulties, a candid admission that sets the stage for the new, more selective approach.

For income-focused investors, the near-term outlook remains anchored by the dividend pipeline. The 2025 payout of 46.00 Swiss francs per share was approved at the annual general meeting and is scheduled for distribution on May 27, 2026. Analysts currently forecast earnings per share of 48.51 francs for the current fiscal year, with the dividend expected to rise to 48.66 francs for 2026, reflecting modest but steady growth.

The next major test for Partners Group's credibility comes on September 1, 2026, when it publishes its half-year report. Investors will scrutinize whether the new investment guidelines are already bearing fruit and whether the fundamentals of the portfolio can definitively rebut the short seller's allegations. Until then, the legal battle with Grizzly Research will remain the dominant narrative for the stock, with any court victory potentially helping to erase a meaningful portion of the accumulated losses.
