Wesco International Inc. (NYSE: WCC) has announced its inaugural inclusion in the Dow Jones North America Best-in-Class Index. This index, formerly known as the Dow Jones Sustainability Index North America, is designed to select the top 20% of companies from the largest 600 North American corporations based on their performance across long-term environmental, social, and governance (ESG) criteria.

The Dow Jones Best-in-Class Index, launched in 1999 and utilizing a free-float market capitalization weighting methodology, is one of the world's earliest series of sustainability benchmarks. John Engel, Chairman, President, and CEO of Wesco International, stated that this inclusion represents a significant recognition for the company, reflecting its focus and commitment to robust governance, standardized processes, and consistent, high-quality management on a global scale.

The company's previously released first-quarter 2026 financial results showed record net sales of $6.1 billion, a 14% year-over-year increase. Data center sales reached $1.4 billion, representing an approximate 70% year-over-year growth. Adjusted earnings per share were $3.37, marking a 52.5% increase compared to the previous year.
