Investor Relations

Letter from the CEO and Chairman

Dear Investors:

Clean Harbors is the leading provider of environmental, energy and industrial services throughout North America.  Founded in 1980, Clean Harbors provides a comprehensive suite of services to more than 50,000 customers in 37 U.S. states, seven Canadian provinces, Mexico and Puerto Rico.  The Company also operates international locations in Bulgaria, China, Sweden, Singapore, Thailand and the United Kingdom.

For the past several years, the Company has grown substantially as we’ve successfully executed our corporate strategy which includes: expanding our service offerings and geographic coverage; cross-selling across segments; capturing large-scale projects; expanding throughput capacity; pursuing selective acquisitions; and implementing cost, pricing and productivity improvement initiatives.

2010 was another year of growth and achievement for Clean Harbors.  As the North American economy began to recover from the global recession, we generated record revenue of $1.73 billion and EBITDA of $315 million.  Demand steadily increased for our Environmental and Energy & Industrial Services as the year progressed.  We also benefitted from our participation in the major oil spill response efforts in the Gulf region and in Michigan.

Looking ahead, we see many reasons for optimism as the world economy continues its recovery.  We are maintaining an active pipeline of potential new projects within both our Environmental and Energy & Industrial businesses.  We also are excited about the prospects for additional strategic acquisition opportunities.  I invite you to return to our website frequently for updates on our progress.  Thank you for your interest in Clean Harbors.
