An announcement from Clean Harbors ( (CLH) ) is now available.

Clean Harbors announced on May 20, 2026, that founder and Executive Chairman Alan S. McKim plans to retire from the Board and his role as Chief Technology Officer once an independent chair is appointed, a move expected in summer 2026 as part of a planned leadership transition. The company emphasized that McKim’s decision is not due to any disagreement with management and highlighted his four-decade tenure transforming Clean Harbors into a $6 billion-revenue leader in environmental services and a critical responder to major incidents from 9/11 and Deepwater Horizon to Covid decontamination, with leadership stressing that his technology focus, safety culture and long-term strategic vision have left a durable operational and cultural foundation for the current co-CEOs and board to build on.

McKim’s retirement caps a career that saw Clean Harbors grow from a small startup to an employer of nearly 25,000 people with more than 20,000 vehicles and over 900 branch locations across North America, underscoring the scale and resilience he helped create. Board and executive tributes framed the transition as a milestone rather than a disruption, signaling continuity for customers, employees and investors as the company maintains its mission of using people and technology to deliver safer, cleaner environments while leveraging the strategic and technological framework McKim embedded in the business.

The most recent analyst rating on (CLH) stock is a Hold with a $315.00 price target. To see the full list of analyst forecasts on Clean Harbors stock, see the CLH Stock Forecast page.

Spark’s Take on CLH Stock

According to Spark, TipRanks’ AI Analyst, CLH is a Outperform.

The score is driven primarily by solid fundamentals (growth, resilient margins, and improving cash generation) and a constructive earnings update (raised 2026 guidance and segment momentum). Technicals support the view with an established uptrend, but the overall score is capped by premium valuation (high P/E) and balance-sheet/leverage-related watch items noted in the financial statements.
