Marsh & McLennan Companies (MMC) reported Q1 2025 results with a slight dip in net income to $1.38 billion, but increases in operating income (to $2 billion) and revenue (up 9% to $7.1 billion) [1]. Subsidiaries Marsh and Guy Carpenter experienced strong revenue growth of 15% and 5% respectively [1]. The company also repurchased $300 million in stock and repaid $500 million in debt [1]. Prior to earnings, some analysts held a slightly negative outlook [3], but the actual results demonstrated growth in key metrics like underlying revenue, adjusted operating income, and adjusted EPS [1]. MMC continues its strategy of acquisitions, recently acquiring Arthur Hall Insurance, which expands its presence in Delaware and Pennsylvania [9], [10]. A shareholder proposal raises corporate governance concerns regarding the chair of the Governance Committee [11], while an insider stock sale by an officer was also reported [13]. Marsh also launched a new cyber insurance facility in Bermuda [2].

Republic Services (RSG) saw a 5.3% stock price increase driven by strong pricing and technological advancements, including the RISE digital platform [1]. Despite this, analysts slightly lowered EPS estimates for the upcoming quarter, even with projected 5.5% year-over-year revenue growth [1]. The company reported Q4 2024 revenue of $4.05 billion, slightly missing expectations but exceeding EPS estimates [2]. While facing mandated odor mitigation improvements at its Sunshine Canyon Landfill due to air quality violations [4], RSG also announced $3 million in community grants [3] and showcased its performance at the Gabelli Funds' Waste & Sustainability Symposium [5]. Strong Q4 2024 results, including 7% revenue growth and $6.46 EPS, along with new recycling and natural gas projects, suggest a positive long-term outlook [6].

Ecolab (ECL) is implementing a 5% surcharge on U.S. products and services to offset rising raw material costs [2], but the market impact remains uncertain. Despite this, the company shows strong financial performance, outperforming its sector and industry peers with positive earnings revisions and a high return on equity [3], [4], [10]. Ecolab secured a $2 billion credit facility for corporate purposes [5] and exceeded its 2024 water conservation goals [8], reinforcing its commitment to sustainability and leadership in water treatment. While a director acquired shares [11], the sale of US$1.5 million in stock by an executive [9] introduces a note of caution. Ecolab will hold its annual meeting virtually [1] and announce Q1 2025 results on April 29th [7]. Long-term growth is projected, driven by a strong product portfolio, strategic acquisitions, and focus on high-growth sectors [4], [6].
