Ariel Investments, an investment management company, released its “Ariel Focus Fund” fourth-quarter 2025 investor letter. A copy of the letter can be downloaded here. Ariel Focus Fund delivered mixed results in the fourth quarter of 2025, declining -0.50% and underperforming both the S&P 500 and Russell 1000 Value indices, which gained +2.66% and +3.81%, respectively, although the fund outperformed both benchmarks over the full year with a +20.97% return. The quarter took place in a resilient U.S. market environment marked by easing inflation, stable corporate earnings, and growing optimism around accommodative monetary policy, alongside continued strength in artificial intelligence and cloud-driven technology stocks, despite volatility stemming from geopolitical risks, labor market softening, and earlier-year disruptions. The fund maintained a disciplined, long-term, bottom-up investment approach, adding selectively to positions such as a security solutions provider while refraining from exits during the quarter. Looking ahead, management remains cautiously optimistic but highlights elevated market concentration, valuation risks in large-cap leaders, and macro uncertainties, emphasizing that increasing dispersion and evolving market leadership should create opportunities for active investors focused on companies with strong balance sheets, durable earnings, competitive advantages, and long-term structural growth potential.

Ariel Focus Fund stated the following regarding ADT Inc. (NYSE:ADT) in its Q4 2025 investor letter:
“Also during the quarter, we added ADT Inc. (NYSE:ADT), a leading provider of automated security solutions for consumers and businesses. With a history spanning more than 140 years, ADT’s brand strength and national footprint are unmatched, supporting its market-leading share, highly recurring revenue base, and attractive free cash flow generation—key drivers for long-term growth. While some investors remain concerned that do-it-yourself (DIY) competitors could erode ADT’s installation and technology-driven advantages, we believe this is a resilient business positioned to benefit from secular smart home adoption trends. We think strategic partnerships with Google and State Farm further enhance ADT’s ability to innovate, expand distribution, and deepen customer engagement. In our view, ADT’s scale, trusted brand and strategic alliances create a durable competitive moat and position the company for sustainable growth and margin expansion over time.”
