Mar Vista Investment Partners, LLC, an investment management company, released its “Mar Vista U.S. Quality Strategy” first-quarter 2026 investor letter. A copy of the letter can be downloaded here. U.S. equities entered 2026 with sustained momentum, despite market leadership evolving significantly over the first quarter. Initial support in equities was hampered by tariff uncertainty, doubts about AI-driven growth sustainability, and emerging private credit concerns, before geopolitical challenges. The quarter saw the lowest performance for U.S. equities in this volatile environment, influenced by rising oil prices due to the Middle East conflict, altering inflation and interest rate expectations. The Mar Vista U.S. Quality strategy returned -7.24% net-of-fees in the quarter vs Russell 1000® Index’s -4.18% and the S&P 500® Index’s -4.33% returns. The firm believes the market is transitioning towards high-quality businesses with strong competitive advantages. Please review the Strategy’s top five holdings to gain insights into their key selections for 2026.

Mar Vista U.S. Quality Strategy stated the following regarding Ecolab Inc. (NYSE:ECL) in its Q1 2026 investor letter:
“During the quarter, we initiated new investments in Ecolab Inc. (NYSE:ECL), GE Vernova Inc (GEV) and QXO Incorporated (QXO). Ecolab (ECL) provides water, hygiene, and infection prevention solutions across industrial, healthcare, and institutional end markets. Its offerings are embedded in customer operations and often linked to regulatory requirements, safety standards, and efficiency objectives. Delivered through a global service network, these solutions contribute to high customer retention and a recurring revenue profile. We believe the company’s scale, technical capabilities, and long-standing customer relationships support a durable competitive position.
The company’s model combines consumable products with service and monitoring, which contributes to revenue visibility and resilience. Because its solutions are integral to maintaining uptime and compliance, demand tends to be less discretionary. Ecolab has also expanded its capabilities through digital tools and analytics, which we believe can enhance customer outcomes and deepen integration within client operations. These factors may support pricing and reinforce its role as a value-added partner.
Ecolab continues to invest in areas such as water management, energy efficiency, and sustainability, which we believe extend its growth opportunities while leveraging its existing platform. The company has demonstrated a history of operational 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 durability of the business model and may contribute to steady growth and margin improvement over time.”
