John Barr of Needham Funds presented his in-depth investment thesis on Clean Harbors (US: CLH) at Best Ideas 2023.

Thesis summary:

Clean Harbors is a leading hazardous waste environmental services firm in the US and may benefit from the reshoring of manufacturing. The company collects and refines used motor oil, roughly 16,000 barrels daily, and has advantages such as scarce hazardous waste incinerators and landfills not replicated by competitors in two decades. The industry is consolidating, offering the potential for improved efficiency and margins. Clean Harbors’ margins are lower compared to non-hazardous waste management peers but may expand due to economies of scale and entry barriers.

About the instructor:

John Barr is a Co-Manager of the Needham Growth Fund (NEEGX). He has been its Co-Manager since January 2010. He also manages the Needham Aggressive Growth Fund (NEAGX). John started on Wall Street in 1995 with Needham as a sell-side analyst following technical software companies, including electronic design automation (EDA) companies. John rejoined Needham in 2009 because of the culture, which lives and breathes growth companies and long-term investing.

From 2000 – 2002, John was a managing director and senior analyst at Robertson Stephens, following semiconductor technology companies. He was an Institutional Investor All-Star and was ranked by Reuters as leader of one of the top software teams. In 2002 John moved to the buy-side and joined Buckingham Capital Management where he served as a portfolio manager and analyst for their diversified industry long/short domestic equity hedge fund.

John’s first career was outside of Wall Street, where he spent 14 years in sales, marketing and management, primarily in the EDA industry. Working in these small companies makes him think like an owner and to look for that trait in his investments. John loves the challenge of identifying businesses with compounding characteristics and getting to know the companies over the course of years. From his industry experience, he looks to invest in companies that he would have liked to have been part of.
