Despite significantly evolving market leadership in the first quarter, US equities entered 2026 with continued momentum. Prior to geopolitical challenges, initial support in equities was disrupted by tariff uncertainty, doubts about AI-driven growth sustainability and emerging private credit concerns. US equities were the lowest performer this quarter in a volatile environment driven by rising oil prices, inflation and changing interest rate expectations due to the Middle East conflict. The Mar Vista US Quality Strategy returned -7.24% net-of-fees in the quarter, compared to -4.18% of the Russell 1000® Index and -4.33% of the S&P 500® Index. The firm believes that the market is moving towards higher quality businesses with strong competitive advantages. Please review the strategy’s top five holdings to get an insight into their key picks for 2026.

Mar Vista US Quality Strategy wrote Ecolab Inc. in its Q1 2026 investor letter. (NYSE:ECL) said the following:
“During the quarter, we initiated new investments Ecolab Inc. (NYSE:ECL), GE Vernova Inc. (GEV) and QXO Incorporated (QXO). Ecolab (ECL) provides water, sanitation and infection prevention solutions to industrial, healthcare and institutional end markets. Its offerings are embedded in customer operations and are often linked to regulatory requirements, safety standards and efficiency objectives. Delivered through a global service network, these solutions contribute to high customer retention and recurring revenue profile. We believe that the company’s scale, technical capabilities and long-standing customer relationships support a sustainable competitive position.
The company’s model combines consumable products with service and monitoring, contributing to revenue visibility and flexibility. Because its solutions are integral to maintaining uptime and compliance, demand is less discretionary. Ecolab has also expanded its capabilities through digital tools and analytics we believe can enhance client outcomes and deepen integration within client operations. These factors can support pricing and strengthen its role as a value-added partner.
As Ecolab continues to invest in areas such as water management, energy efficiency and sustainability, we believe this enhances its growth opportunities while leveraging its existing platform. The company has demonstrated a history of operating discipline and capital allocation, contributing to attractive returns on invested capital. While macro and execution risks remain, we believe long-term demand drivers, including water scarcity and regulatory requirements, support the sustainability of the business model and can contribute to stable growth and margin improvement over time.
