Ironvine Capital Partners emphasized in its latest investor letter that long-term equity returns are ultimately driven by underlying earnings growth, noting that businesses held across its portfolios increased earnings between 12% and 16% in 2025, while holdings have compounded profits at roughly 15%–18% annually over the past nine years. The firm expects another year of mid-teens earnings growth across its companies in 2026, supported by durable competitive advantages, reinvestment opportunities, and structural industry tailwinds. Performance for the Ironvine Concentrated Equity Composite returned 11.27% in 2025, compared with 17.88% for the S&P 500 Index, while the Ironvine Core Equity Composite gained 9.68% during the year. The letter highlighted several major portfolio holdings benefiting from trends such as cloud computing expansion, aerospace maintenance demand, datacenter and semiconductor growth tied to artificial intelligence, resilient credit markets, the continued digitization of payments, and the global need for enterprise software and risk-management services. Despite acknowledging uncertainties ranging from regulatory developments to cyclical industry conditions, the firm remains confident that owning durable, high-quality businesses with strong reinvestment opportunities can generate double-digit long-term returns even if market valuations moderate.

In its fourth-quarter 2025 investor letter, Ironvine Capital Partners highlighted stocks like Amphenol Corporation (NYSE:APH). Amphenol Corporation (NYSE:APH) designs and manufactures electronic and fiber optic connectors, sensors, and interconnect systems used across communications, automotive, and industrial applications. The one-month return of Amphenol Corporation (NYSE:APH) was -13.50% while its shares traded between $56.45 and $167.4 over the last 52 weeks.

Ironvine Capital Partners stated the following regarding Amphenol Corporation (NYSE:APH) in its Q4 2025 investor letter:
“When the books officially close on 2025 in a few weeks, it will mark a historic year at Amphenol Corporation (NYSE:APH). We estimate revenue will have grown over 50%, operating income north of 80%, and free cash flow by approximately 90%. And that is before considering that Amphenol closed the largest acquisition in its history just last week. The primary growth accelerant has been the explosion in demand for interconnect in AI-focused datacenters where the company is winning outsized market share. Our investment in Amphenol was not based on a surge in AI demand, and we do not know how long the present capital cycle will last. We have confidence, however, that the growing and constantly evolving demands of the electronics industry are likely to continue to produce opportunities for which Amphenol is structurally advantaged to capitalize on to the long-term benefit of shareholders.
