Meridian Funds, managed by ArrowMark Partners, released its first-quarter 2026 investor letter for “Meridian Small Cap Growth Fund”. A copy of the letter is available to download here. The US equities market started 2026 with volatility driven by trade policy uncertainty and heightened geopolitical risks. Initial gains were attributed to confidence in domestic companies and the Federal Reserve easing. However, sentiment deteriorated following increased tariffs and military strikes by the U.S. and Israel against Iran. During the quarter, Meridian Small Cap Growth Fund returned -8.37% compared to the Russell 2000 Growth Index’s -2.82% return. The Fund’s relative underperformance was driven by industry allocation effects, while stock selection contributed positively. Despite the market environment, the fund prioritizes high-quality businesses characterized by durable competitive advantages, robust balance sheets, and a clear outlook for sustainable earnings growth.

Meridian Small Cap Growth Fund stated the following regarding Zenas BioPharma, Inc. (NASDAQ:ZBIO) in its Q1 2026 investor letter:

Zenas BioPharma, Inc. (NASDAQ:ZBIO) is a clinical-stage biopharmaceutical company focused on developing treatments for autoimmune diseases, with its lead candidate targeting IgG4-related disease, a rare and underserved inflammatory condition. The company offers a differentiated approach with a potentially safer profile and more convenient at-home dosing compared to existing therapies. Shares declined after Phase 3 clinical data, while meeting statistical significance, showed a flare reduction rate that fell short of market expectations and compared unfavorably to a competing therapy. We continue to evaluate the opportunity but believe the company’s differentiated safety and dosing profile may still support a meaningful role in treatment.”
