Meridian Funds, managed by ArrowMark Partners, released its “Meridian Growth Fund” fourth-quarter 2025 investor letter. A copy of the same can be downloaded here. U.S. equity markets experienced a quarter shaped by optimism around potential monetary easing and caution related to economic growth and valuations. Early gains were driven by strong AI-related earnings and the US Federal Reserve’s rate cut in October. However, market sentiment cooled later in the quarter due to mixed signals from the Fed regarding future policy. Despite this moderation, the quarter contributed positively to robust annual results, with large caps rising 17.4% for the year and 2.4% in the quarter, while small caps gained 12.8% for the year and 2.2% in the quarter. Value stocks outperformed growth, returning 3.3% versus 1.2% for the quarter. Market factors and sector effects were mixed in the quarter. Against this backdrop, the Fund delivered a return of -0.39% (net) in the quarter, underperforming the Russell 2500 Growth Index’s 0.33% return. As the market heads into 2026, the firm is closely watching the factors that may affect market returns, including monetary policy changes with a new Fed Chair and the sustainability of AI investments due to high valuations among hyperscalers. The firm continues to focus on high-quality businesses with strong competitive advantages, solid balance sheets, and clear sustainable earnings growth.

Its automated insulin delivery systems are well-positioned to gain share in a sizable and expanding addressable market, where a majority of Type 1 diabetes patients still manage insulin manually.
The stock appreciated during the quarter, supported by revenue that exceeded expectations and an encouraging growth outlook. Performance was bolstered by a higher proportion of sales through the pharmacy channel, which offers more favorable economics.
