Alan S. McKim has watched the value of his holdings fluctuate over the years. In 2019, his holdings peaked near $333 million but saw a substantial drop in early 2020, falling to around $223 million before gradually recovering. By mid-2023, his holdings showed strong growth again, reaching as high as $648 million. This demonstrates Alan’s commitment to the company as his wealth is tied significantly to its stock performance, and he remains heavily invested in Clean Harbors' success. His shares represent about 7.2% of the company, which reinforces his alignment with shareholder interests and highlights his role as a long-term steward of the business.
